DR. NIGHTINGALE: It is one minute after 8:00 in
the morning. Good morning. I'm Dr. Stephen Nightingale,
the Executive Secretary of the Advisory Committee on Blood
Safety and Availability and welcome to our Sixth Meeting.
The following announcement is made as part of the
public record to preclude even the appearance of a conflict
of interest at this meeting. General applicability has been
approved for all Committee members. This means that unless
a particular matter is brought before this Committee that
deals with a specific product or firm, it has been
determined that all interests reported by the Committee
members present no potential conflict of interest when
evaluated against the official agenda.
In particular, as specified in Title XVIII of the
US Code at Chapter 208(b)(2), a Special Government Employee--which all voting Committee members are--may participate in
a matter of general applicability even if they are presently
employed or have the prospect of being employed by an entity
that might be affected by a decision of the Committee,
provided that the matter will not have a special or distinct
effect on the employee or the employer, other than as a part
of the class. The example given in 5 CFR 2640.203, which
implements Title XVIII of the US Code, is as follows:
A chemist employed by a major pharmaceutical
company has been appointed to serve on an advisory committee
established to develop recommendations for new standards for
AIDS vaccine trials involving human subjects. Even though
the chemist's employer is in the process of developing an
experimental AIDS vaccine and therefore will be affected by
the new standards, the chemist may participate in
formulating the advisory committee's recommendations. The
chemist's employer will be affected by the new standards
only as part of the class of all pharmaceutical companies
and other research entities that are attempting to develop
an AIDS vaccine.
Committee members have been given a copy of this
section of the Code. Additional copies are available at the
desk.
In the event the discussions involve a specific
product or a specific firm in which a member has a financial
interest, that member should exclude him- or herself from
the discussion, and that exclusion will be noted for the
public record.
With respect to the other meeting participants, I
ask in the interest of fairness that they disclose any
current or previous financial arrangements with any specific
product or specific firm upon which they plan to comment.
Finally, I will make every effort to see that the
transcript and the summary of this meeting and the final
draft of any recommendations will be posted on our Web site
by the close of business Monday, November 30th. The Web
address is www.hhs.gov/partner/Blood Safety.

DR. NIGHTINGALE: Thank you. The agenda for
today's meeting is the Seventh Report of the House Committee
on Government Reform and Oversight titled "Hepatitis C:
Silent Epidemic, Mute Public Health Response." Dr. Caplan,
the Chairman of the Advisory Committee, will preside.
Dr. Caplan?
CHAIRMAN CAPLAN: Well, we have a busy day this
morning. I want to remind the Committee that we've really
been asked by the Surgeon General to take a look at this
Seventh Report of the House Committee on Government Reform
and Oversight from October 15th. We've sent it to the
Committee, I think, at least four times, in my memory of
mails that have come. So I hope that the message was clear
to pay attention to this.
I want to just look at three findings and three
recommendations in brief. You know, when we've met in the
past, we've had to scramble to the slides and the overheads,
concocting language as we drive toward consensus on certain
matters pertaining to blood safety and availabilty. But in
this case, we've got something to respond to by the end of
the day. It doesn't limit us, but there are some things
we're supposed to say something about.
The findings of this report were as follows: The
Federal response to the hepatitis C epidemic has lacked
focus and energy. Secondly, the proposed HCV lookback is
too limited. Third, private organizations with some Federal
assistance have taken the lead in HCV public education
efforts. I can say that if you read the report, that was
said with a critical edge to it, that private organizations
should not be taking the lead on this. And there are a
series of recommendations, and I'm inside the report on page
2 of it, just to remind you again.
The Secretary of HHS should take the lead in
coordinating the Federal public health response to the
hepatitis C epidemic, including implementation of a research
plan. The Department of Defense should test recruits,
active-duty personnel, and those about to be discharged for
hepatitis C infection. The Department of Veterans Affairs
should conduct additional studies of the prevalence of
hepatitis C in veterans' populations. The hepatitis C
lookback plan should be expanded, and the Federal education
campaign for HCV infection should be launched immediately.
What this report wound up concluding, arguing, was
that they were not convinced that the Government was making
the public health response to the hepatitis C epidemic that
was required, and so we've been asked to think about, listen
to testimony today on those matters, and then to reaffirm or
add or come back and change what we've been told by that
particular subcommittee of the House about this particular
problem.
I want to just note something else that caught my
eye. I collected a couple of things since our last meeting.
Some of them, again, Dr. Nightingale, Mac, did a great job
getting materials out to you. Some of you know there were
articles in the New England Journal last week on combination
therapy for hepatitis C. While far from a cure, they were
optimistic. I'm not going to go through those articles or
the editorial ran, but things are moving fast in the area of
intervention for hepatitis C. That means, I think
personally, that the ante is raised about the importance of
lookback. The ante is raised about the importance of public
education campaigns.
I have a friend who has hepatitis C, and he's been
trying very hard to get access to different forms of
therapy, combination therapies. He believes that the right
response for him with his infection is to try and clear the
virus from his body. And I asked him if he felt that this
Government and our country was doing what we should to
respond to hepatitis C epidemic, and he said no, because
every day he meets people who didn't realize that they might
be infected.
That is not a good situation. So it is, I think,
our mandate to the American people to make sure that if this
problem is out there and if there are steps they can take,
either through the cessation of drinking, watching what they
do with ibuprofen, getting themselves vaccinated against
other forms of hepatitis, not sharing razors, or moving
towards some of these emerging interventions, we have to
make sure that people are aware of what they need to be
aware of, that medical and health communities are able to
answer questions and inform them.
So that's how I see our task, as against that
backdrop of saying, well, if there are steps that can be
taken to reduce infection, if there are steps that might be
taken to reduce the burden of the disease, if, as other
statistics show, we've got 4 million people infected and an
explosion in the number of people getting liver transplants
due to this particular virus, we have to make sure we're
doing all that we can do in terms of a response, both public
and private, to hepatitis C.
I'd just mention one last comment, and then we'll
go to the first witness.
This is a statement from the American Association
for the Study of Liver Diseases. They had a meeting in
Chicago and thoughtfully sent me a statement about one of
the things they are bothered about. And they reported at
that meeting about the challenge of hepatitis C, what it was
doing in terms of cost and burden to the American people.
But this statement caught my eye.
The main reason for the drastic increase in severe
hepatitis C-related liver disease--that means leading to
transplant, leading to death--is that 90 percent of people
with chronic hepatitis C don't know they have it.
Well, that's not an acceptable situation. If
that's what the problem is, then we've got to make sure we
are vigilant in pushing to make sure that that number is
much smaller.
So I'll stop there. That's our charge. We want
to be mindful of the fact that by the end of the day we have
to say something about this report and what we want to tell
the Surgeon General and, through indirection, the other
Federal agencies here and even Congress. I suspect we might
even say if we want them to spend some more money, we might
say they should spend some more money. What the heck? It's
not ours. Well, indirectly. It's so far distant.
So we can move now to the first witness, having
reminded you why we're here and what we're trying to do. I
think we're going to hear from CDC first?
DR. NIGHTINGALE: Hear from CDC.
CHAIRMAN CAPLAN: I don't know who we've got from
CDC. Oh, Dr. Alter?
DR. ALTER: Thank you. Good morning. I'm Miriam
Alter from the Hepatitis Branch of the Centers for Disease
Control and Prevention in Atlanta, and you should all have a
hard copy--most of you should have a hard copy of the
presentation. There may be one or two of you who do not
because we may not have brought enough copies. But if
that's the case, I'll be showing the exact same information
on the slides, and we will get you a hard copy if you need
it.
As the first presentation today, we would like to
review the guiding principles which underlie the
recommendations made by this Committee last year.
Identifying transfusion recipients at potential
risk for HCV infection can be accomplished with two
approaches: targeted lookback, which is the direct
notification of prior recipients of donors who later tested
positive for HCV, and how we define positive may, in fact,
be the major crux of all the issues we're dealing with; and
general lookback, which includes public notification through
broad education campaigns about the need to be tested, as
well as education of health care professionals to routinely
ascertain transfusion histories of their patients and test
those with such a history.
Targeted lookback for transfusion recipients at
potential risk for HCV infection has several advantages. It
focuses on a specific group known to be at risk. It reaches
persons unaware they were transfused. And it is perceived
as proactive.
This approach also has several disadvantages.
Many notifications may be based on false positive results
because supplemental or confirmatory testing is not
available on donors who tested repeat reactive for the anti-HCV. This approach will not reach recipients from donors
testing falsely negative unless sensitive tests or donors
who were never tested because they donated before testing
was available. Records might not be available as far back
as 1988, which is the current time frame for the lookback.
Many individuals are untraceable, and based on limited
evaluation, there has been a poor response on the part of
recipients to programs such as this in the past as well as
in other locations.
General lookback or notification for transfusion
recipients at potential risk for HCV infection also has
several advantages. It is not dependent on donor status or
record availability, and it reaches at-risk persons who
would not otherwise be identified--that is, recipients who
receive blood from donors who tested falsely negative on the
less sensitive test or who received blood from potentially
infected donors before testing was available.
The disadvantages of this approach is it might not
reach some individuals who are unaware they were transfused,
it is perceived as not proactive, and there is no
substantial data on its effectiveness.
In order to maximize the advantages and minimize
the disadvantages of notifying transfusion recipients at
potential risk for HCV infections, the Committee made its
current recommendations for identifying these individuals,
which includes a combination of both approaches:
Direct notification of prior recipients of donors
who later tested confirmed positive by multiantigen assays,
which were widely implemented by July 1992. In the guidance
provided by FDA, this is further clarified, and, in fact, it
will include a small number of recipients who received blood
from donors who had repeat reactive antibody tests that were
not confirmed in order to include the entire time period
that encompasses multiantigen testing.
The current recommendation also provides for
general notification of all persons transfused before July
1992.
By using both of these--this slide illustrates the
components of this comprehensive strategy using both
approaches. Now, if we start--actually, Jean, can I borrow
your...
If we start here in 1998, for donors who have
donated previously and come back to be tested--and have come
back to be tested after multiantigen tests were widely
implemented, which is from July 1992 forward, lookback will
be triggered for their recipients if they donated
previously, those previous donations--if they donated
previously, back to 1988 or as far as--or as far back as
records are available.
So keep in mind that if a donor who is--let's say
a donor donated in 1992 and was negative on the first
generation--first-version screening test, this donor then
comes back to donate again in June of 1996 and is now found
to be positive on both the multiantigen screening and
supplemental assays, lookback will be triggered for the
prior donations from that individual. This individual might
have donated not only back in 1992, but perhaps back in 1989
as well.
So that the time period actually refers to when
the donor is tested, not when the recipient was transfused.
So that the targeted lookback refers to prior transfusion
recipients of donors who donated previously and came back to
be tested with a multiantigen assay.
General lookback will encompass all individuals
transfused prior to 1992, which will include recipients of
donors, of repeat donors who tested repeat reactive but
unconfirmed on the first version of the assay. So you'll
notice that, in fact, there is considerable overlap between
the two approaches.
In discussing the public health issues of these
approaches, we are not considering costs or any other
measures of outcome other than the immediate impact of the
notification on the recipient. This slide shows the
estimated number of transfusion recipients for notification
using the time period specified in the recommendation made
by this Committee last year.
We have updated the numbers based on our
understanding of the availability of supplemental or
confirmatory results on a small percentage of donors testing
repeat reactive on the first version assay. Although the
absolute numbers may have changed from previous versions,
the magnitude of the relationship between each category has
not.
Now, let's look at the column labeled single
antigen. Single antigen testing was first introduced in May
of 1990 and spanned about a two-year time frame. The total
number of recipients for notification based on repeat donors
who tested repeat reactive for anti-HCV by the single
antigen assay has been reduced by about 30 percent from the
previous estimate because we have recently been informed
that about 30 percent of these were tested by RIBA, and
those results are available, and about 25 percent of those
are expected to be positive--are estimated to be positive by
RIBA, and that's why--and that reflects this number of those
who have been tested by RIBA and found to be positive as
well as those who have not been tested.
So of the 500,000-plus recipients estimated that
will require notification based on single antigen testing,
about a third will be recipients of true positive donors.
This includes donors who were tested by RIBA and found
positive, plus the estimated number of RIBA positive donors
among those not tested. So a true positive donor for the
purposes of this presentation is defined as someone whose
antibody is a true positive.
The percentage of individuals who receive a false
notification--that is, their donor was not infected with HCV
and their antibody was not a true positive--is about 68
percent, or over 300,000. Now, of all those notified, we
expect, based on survival rates for persons transfused five
to ten years ago, about 10 percent of these individuals will
be alive. We will miss through a targeted lookback about
43,000 individuals because their donors tested falsely
negative on this assay.
Now, if we look at the second version--I'm sorry.
If we look at the second time period, which is after
multiantigen testing was widely implemented, we find that a
little over 300,000 recipients will be triggered for
notification. Of these, because most have RIBA testing
results, 90 percent of the notifications will be based on a
true positive donor and only 10 percent on a false positive.
Again, based on survival rates for individuals
transfused in the past, about 18 percent of these are
expected to be alive, and because the sensitivity of these
tests were greater, only about 10,000 individuals would be
missed through a direct notification.
Based on these calculations, we can summarize the
consequences of performing targeted lookback for all
recipients since screening was implemented in 1990 based on
their anti-HCV screening results, without regard for whether
or not confirmatory testing was done--that is, if
confirmatory testing is done, the notification would be
based on that. If confirmatory testing was not done, then
the notification would be based on the screening test
results.
The estimated target population, which is a
combination of the two groups I showed you on the previous
slide, is about 850,000. An average of 53 percent of these
notifications would be made to recipients at potential risk--that is, their donors were truly anti-HCV positive. This
ranges from a low of 32 percent for recipients of donors
tested by single antigen assays to a high of 90 percent for
recipients of donors tested by multiantigen assays.
Now, as we stated previously, this approach
fulfills the right to know. It provides the opportunity for
the individual to determine their infection status and to
obtain, if they're positive, follow-up or evaluation for
clinical disease and possible treatment, recognizing that
most, or 80 to 90 percent of these individuals, are already
deceased from other causes.
On the other hand, 47 percent of these
notifications will be made to recipients not at risk. Only
10 percent would be falsely notified using multiantigen
assays, but as many as 68 percent would be falsely notified
if we based notification on single antigen testing.
These false notifications would be made to as many
as 400,000 individuals or their families, and certainly the
right to know is an underlying principle of this program.
But this principle also demands that the information
provided have a high level of diagnostic certainty so that
this activity does not generate more harm than good.
Providing false information might be detrimental
and will certainly require additional counseling for
reassurance. Furthermore, an additional 50,000 recipients
at risk would not be notified through this approach because
their donors tested falsely negative.
As I said before, these estimates have been
revised based on the availability of supplemental or
confirmatory testing of a small proportion of version 1.0
donors, information that was not known a year ago.
Keeping with the guiding principles of trying to
notify as many recipients as possible who received blood
from a true positive donor, we can estimate the number of
transfusion recipients for notification based only on donor
testing status without regard specifically for the time
frame in which the donor was tested, not when the recipient
was transfused.
If we look at the number of notified recipients--the number of recipients who will be triggered for lookback
based on donors tested by the single antigen screening assay
with no supplemental or RIBA testing, then we have about
480,000-plus recipients, of whom about 25 percent are
estimated to have received a donation from a donor who later
tested truly positive. Seventy-five percent did not receive
a unit from a donor who was infected. Again, the rest of
the calculations remain the same as previously.
If we base targeted lookback on both single and
multiantigen-tested donors who were also tested by RIBA,
then about 360,000 recipients would be notified directly, of
whom 91 percent received blood from a donor who later tested
truly positive, and only 9 percent would be notified when
they were--would be notified but had received blood from a
donor whose test result was later--was actually a false
positive.
Thus, we believe that by modifying slightly the
original recommendation that this Committee made for
identifying transfusion recipients at risk for HCV infection
will retain the spirit of the original recommendation,
maximize the direct notification of individuals at risk, and
minimize the number of false notifications. This would
include targeted notification based on supplemental testing
results without regard for time period, including all of the
provisions that are currently included in the FDA guidance.
General notification for all persons transfused
before July 1992, and this would accomplish reducing the
false notifications from a potential high of 400,000 to a
low of 32,000, and minimizes the number of recipients missed
due to donors testing falsely negative.
This approach differs very little from the
previous one, except to take advantage of all the
supplemental or confirmatory testing that's available,
thereby minimizing the number of false notifications; so
that recipients transfused from donors who later came back
to be tested and tested positive using either single or
multiantigen screening assays, plus the results of
supplemental assays, would be directly notified. This would
include all recipients of multiantigen-tested donors as well
as about 30 percent--as well as a small proportion of
recipients from donors who came back during first version
testing.
In addition, we again go even further with general
lookback to include all recipients tested before--who
received blood before July of 1992.
Now, in order to encourage individuals with a
history of transfusion to be tested, as well as to ensure
that these individuals receive the right follow-up, our
major focus in terms of education has been the health care
professional because they need to be able to adequately
address the patient's needs. Education of the health care
professional started well before the Committee's
recommendations for lookback for transfusion recipients.
In March of 1996, the NIH issued a consensus
statement on the management of hepatitis C. In November
1997, the CDC, in collaboration with the Hepatitis
Foundation International, broadcast an interactive, live
teleconference by satellite on diagnosis, clinical
management, and prevention of hepatitis C, targeting primary
care physicians, which was broadcast to more than 2,000
downlink sites.
Then in January 1998, Secretary Shalala agreed
with the recommendations of this Committee calling for
lookback--two approaches, targeted and general--to identify
recipients of HCV-infected blood.
In February of 1998, a Hepatitis Summit was
sponsored by the American Digestive Health Foundation and
focused on providing health education messages to minorities
as well as information to health care professionals on
hepatitis C.
In March of 1998, and revised in September of
1998, the FDA issued guidance for industry for both
quarantine of units found to be positive for anti-HCV as
well as notification of blood collection--as well as
notification in order to carry out directed or targeted
lookback.
In April of 1998, the CDC convened a meeting of
representatives from the American Red Cross, America's Blood
Centers, the American Association of Blood Banks, and the
Council of State and Territorial Epidemiologists to discuss
implementation issues for lookback and coordination of
efforts.
The American Association of Blood Banks formed its
Interorganizational Task Force on HCV Lookback to coordinate
efforts nationwide, and the CDC updated its Web site in
order to include current information on this effort as well
as information in general about hepatitis C.
Between June and September 1998, educational
materials and screening guidelines were mailed to more than
250,000 physicians and other health care professionals,
including members of the American Academy of Family
Practitioners, the American Academy of Pediatrics, the
American College of Physicians, the American College of
Obstetricians and Gynecologists, and the American College of
Surgeons.
A similar mailing was made when the
recommendations for prevention and control of HCV infection
and HCV-related chronic disease was published in an MMWR in
October of 1998. These guidelines, a copy of which should
have been--either you received by mail from us or was
provided to you by Steve Nightingale, includes guidelines
for preventing transmission of HCV, identification,
counseling, and testing of persons at risk, including
transfusion recipients, and providing appropriate medical
evaluation and management.
Between October 1998 and January of next year, we
will be distributing education materials to transfusion
services, including a brochure or pamphlet for transfusion
recipients specifically which is entitled "Get Tested for
Hepatitis C," and you have a copy of it that I provided to
you this morning.
These educational materials include letters that
CDC has worked with the AABB Interorganizational Task Force
on that transfusion services can use to notify both patients
and physicians, which explains the risks involved, why
they're being notified, what they can do about it, and where
they can get tested.
Early next year, we will be finalizing the
protocol to evaluate the effectiveness of our lookback
activities, and we'll also be providing software to
transfusion services to assist in targeted lookback.
By March of 1999, CDC's public advertising
campaign will be launched to notify the public about the
need for testing of transfusion recipients for hepatitis C.
We will also have established a Web-based training site for
health care professionals on HCV prevention, including
testing of transfusion recipients. And by the middle of
next year, we hope to begin evaluation of the effectiveness
of these lookback efforts.
As promised, in the January 1998 memo from
Secretary Shalala, we have gone forward in collaboration
with the Agency for Health Care Policy Research and FDA with
the development of a plan to evaluate the effectiveness of
both the targeted and general lookback efforts. The
objectives of this plan are to evaluate the effectiveness of
both approaches for identifying persons infected with HCV,
encouraging persons found positive to obtain appropriate
medical follow-up, and its effectiveness for promoting
healthy lifestyles and behaviors among those found to be
infected, such as decreasing or eliminating alcohol
consumption. In addition, we will collect cost data in
terms of dollars and personnel resources so that we can
evaluate the cost-effectiveness of these programs.
This evaluation plan includes two national
surveys, one of blood collection establishments and the
other of transfusion services, to collect the basic
information about all of the donors who are triggering
lookback as well as the recipients who are eligible for
notification. It will also include follow-up studies of a
sample of transfusion recipients presumed to have been
notified and/or who have obtained HCV testing to determine
the outcome and impact of the notification process on the
transfusion recipient, including those who test negative;
and for the general notification efforts will include a
survey and study of private and public health care services
to determine the extent of HCV testing of persons with
transfusion history.
As a result of this evaluation, we will determine
if our efforts need to be expanded in order to more--to
identify a larger number of transfusion recipients who may
be at risk of HCV infection.
We believe that, with a slight modification, the
recommendations that this Committee made represent good
public health practice and minimize the negative impact on
individuals who are not at risk of acquiring this infection.
We also believe and feel have demonstrated that the
Department of Health and Human Services has actively gone
forward with a variety of programs to achieve this
important--to achieve a successful outcome to this important
public health program.
Thank you.
CHAIRMAN CAPLAN: Thank you, Miriam.
First, let's take some time for questions. I
wanted to lead off with just one question about the public
health campaign that you've undertaken for physicians and
health care professionals, which I've been following very
closely and I think is great.
I noticed an editorial in the British medical
journal, The Lancet, although I've seen these around, too,
and I just wanted to get your opinion about the public
health campaign. Basically what it said is how much money
would be needed to do a thorough public health campaign.
The current CDC budget for HCV is about $10 million. It's
far too little. It's far smaller than the amount to do the
job than the CDC asked Congress for, which you'll recall we
had some discussion here about it being more than a $48
million level. It's only a portion of what the American
Liver Foundation has told us might be necessary for a
campaign.
What I'm asking is, as we get the materials out,
begin the education campaign, are the resources there, in
your opinion, to really push the materials that are being
developed aggressively, adequately, to the health care
community? Can we get the message out given what the
commitment is?
DR. ALTER: I think given--do you want to, Kris--
DR. MOORE: Go ahead, but I have a comment on
that, too. Go ahead.
DR. ALTER: Although Hal Margolis might want to
add to this, I think we have actually very widely
disseminated this information. In terms of the education of
health care professional, I don't know how much more we
could saturate the market with our current materials. What
I think would be important is resources to evaluate whether
or not what we have done is effective and whether or not we
need to do something additional.
DR. MOORE: As someone who works in a state health
department, I think CDC has really done an excellent job in
trying to get information out; but I also think that there's
this conception that if you put out an MMWR article, people
read it, people absorb it, people learn that information.
And having worked with community--
CHAIRMAN CAPLAN: Is that not true?
DR. MOORE: Well, I'm beginning to believe it's
probably not fully true, with work in this area but also in
a number of other areas related to immunizations, and take
pneumococcal vaccination, for example, where we're doing a
number of other kinds of projects, or GBS guidelines. I
mean, there are so many different levels where this has been
demonstrated over and over again.
But I really think there is a very strong need to
have people at the state level that can really help to push
this information. For example, in Minnesota, because we've
been interested in this, we've done four or five provider
conferences. We've met with the Association for
Practitioners in Infection Control several times. We've
sent information to all the hospitals in the state. We've
worked with the blood banks, and we've done a lot of other
steps that I think if you really want providers to change
practice, you have to have somebody at the local level at
them, you know, just kind of putting the messages out over
and over again.
And I would really advocate for resources to CDC
so that they could then put some categorical funding out to
states. I just think without those resources, it just
doesn't happen to the level that we would like to see. And
I know that this is something that's been discussed at CDC,
and the resources just simply haven't been there. I'd
strongly advocate for that.
DR. ALTER: You're absolutely right, Kris, and the
resources that Dr. Caplan referred to were part of the CDC's
overall nationwide campaign--excuse me, nationwide plan for
HCV prevention and control, which includes not only primary
prevention activities but the identification of everyone at
risk, of which, as we all understand, the transfusion
recipients are very important, but as small component of
that. So Kris' comment is well taken and extremely
important.
In terms of some of the broader issues, however,
the resources--we have actually dedicated--I think had
sufficient resources to deal with both the--at least the
educational programs directed at the health care
professional and will have for the public. But we need to
direct some of those efforts at a very local level in order
to get the message across.
DR. EPSTEIN: Miriam, I have a technical
questions. When you looked at EIA 1.0 RIBA tested to
develop the numbers for recipients, were you including
indeterminate results of RIBA 2?
DR. ALTER: For the purposes of these estimates, I
didn't. I assumed an overall rate of positivity of about 25
percent, recognizing that RIBA 2.0 indeterminates might be
included in there. I looked at some of the--Steve
Kleinman's publication, looked at the percentage who were
indeterminate in that group, and I imagine since that was a
relatively--it's only 40,000 or so donors, you know, that
the range of indeterminates probably varies widely. But I
didn't include them because it was a little too difficult to
estimate.
DR. EPSTEIN: But it would drive the numbers up?
DR. ALTER: The number who would get notified,
yes, it would, and it would drive the number of false
notifications up as well. But the magnitude of the
relationships, again, would remain the same, and I think
that that's--in principle, the principle here are the number
of individuals who would be falsely notified, and since we
have an approach to deal with that, the numbers could change
tomorrow of next week, but the magnitude would remain the
same.
DR. PENNER: With respect to the first-generation
hepatitis C antigen testing, that was the 1990 to 1992--the
1990 to '92 assays?
DR. ALTER: That's correct.
DR. PENNER: If I'm reading this correctly, you're
saying that you'll have to notify 54,000 live recipients, to
let about a third of them know that they were truly exposed
to the live virus?
DR. ALTER: No. The number of notifications that
would have to be made is over 500,000.
DR. PENNER: However, 54,000 of those are alive,
you're saying?
DR. ALTER: Expected to be alive, right. But a
lot of them, they won't know that at the time that they send
out the notification.
DR. PENNER: So it's really 54,000 that you're
concerned about who--
DR. ALTER: No, because--I'm sorry.
DR. PENNER: About two-thirds of those which would
be receiving false positive testing.
DR. ALTER: You could look at it that way. On the
other hand, keep in mind their families receive these
notifications as well.
DR. PENNER: And so the agency is saying that you
prefer to make the decisions for them so they don't get
upset by this?
DR. ALTER: No--
DR. PENNER: And those individuals who happen to
have been--really received the live virus would not be
notified in this way.
DR. ALTER: We feel that it's just as important
for people not to receive false notification as it is for
people to receive notifications based on a high level of
certainty. And since these individual--since we're using
two approaches of notification--it isn't that we're not
notifying people. It's that we're using two different
approaches. And everyone who was transfused before July of
1992 will be encouraged to be tested through very aggressive
public education campaigns. The fact that they won't
receive a specific letter of notification will need to be
evaluated to determine whether or not we need to go further
with efforts to get individuals tested.
DR. PENNER: We already heard from an expert that
spoke at this Committee that direct notification by mail
would be much more effective than a general announcement to
the public.
DR. ALTER: If I remember correctly, it was a
marketing individual who spoke and who did an excellent job
at presenting that. And, yes, this--that might be a slight
overstatement of what he said, and you know what? To be
quite honest, I don't think we know what the impact of these
two approaches is going to be. I think in the next
presentation you're going to see some examples of other
notification programs and the responses to them. And I
think that our plans for evaluation will help us answer
that.
DR. PENNER: There's one other issue, though.
Many patients do not know that they've been transfused,
including those who are in prenatal situations or at least
newborns, as well as a number of patients who have undergone
surgical procedures. They're completely unaware that
they've ever received any blood transfusion. What about
those individuals?
DR. ALTER: Well, as I mentioned early on, there
are advantages and disadvantages to each approach, and
neither of them is perfect. And, yes, you can miss some of
the individuals who are not aware that they were transfused.
I think in some studies of HIV it was estimated
it's about 12 percent of those transfused. However--and
some of them, you're right, will be missed.
However, you know, to somewhat alleviate that
number, we will be encouraging--we will be--part of our
messages will be risk factors for transfusion so that people
will be made aware that they could have had a transfusion,
they should find out about it, as well as the same types of
messages to physicians when they're looking at their
patients' histories. Neither of these approaches is
perfect. We feel that the combination of the two maximizes
the advantages of both of them and minimizes the
disadvantages of both of them.
DR. PENNER: The disadvantage is being frightened
by the fact you received the letter and it may not--
DR. ALTER: And you're not at risk.
DR. PENNER: And you're not at risk.
DR. ALTER: That's correct.
DR. PENNER: And despite the fact the British and
the Canadians have already gone through this and have
accepted the fact that the first-generation testing was
worthwhile notifying the individual recipients?
DR. ALTER: You're going to hear some of those
results, I think in Dr. Mied's presentation.
CHAIRMAN CAPLAN: We're going to take two more
comments. We'll do one from Marian, and then I think I have
one pressing question that I was holding in reserve, and
then we've got to get to the FDA testimony, but the themes
will stay here.
DR. SECUNDY: I want to try to bring this down to
the level of the most simplistic. As I heard you--
CHAIRMAN CAPLAN: Hit that mike a little.
DR. SECUNDY: You indicated that at some point in
time--and I guess I need to know what time period would be
involved--that you would look at your results using these
approaches and make a determination of whether or not they
had worked sufficiently or if you were going to need to step
up efforts.
I've got one comment and a question related to
that. It would appear to me, from what I'm understanding,
that with the exception of some minor incremental changes,
we've been at this for two years, and we have looked at
those results, and it seems to be somewhat mixed in terms of
a sense of whether or not any of that has worked.
But the question that I have is: What time frame
are you suggesting for this approach to be used and at what
point will you evaluate and what criteria are you using to
determine whether or not it has worked? And then, finally,
what do you anticipate might be involved in stepping up
efforts?
DR. ALTER: Okay. Everything that's been done in
the last two years has led up to the notification process,
whichever approach is involved, because the education had to
be laid as groundwork before we could aggressively pursue
testing of individuals at risk. That's number one.
As provided for in the current FDA guidance,
transfusion--notification of transfusion services of
recipients who need to be notified must begin by March of
'99. Some of this has begun already, as I imagine you'll
hear from some of the other speakers today.
However, the bulk of the notification will begin
in March of next year, and it is an ongoing process. Given
the hundreds of thousands of people involved, it will take
time to complete notification of everyone. In the same
month, we will begin our public education campaign.
We will need to give both the public education
campaign, as well as the notification process, time to
settle in, time for people to hear the message or receive
the message in the mail and take some action. So I would
think that in terms of evaluation, we wouldn't begin to
really look at it until, let's say, the end of '99. In
other words, we'd have to implement the procedures to look
at it at the time the notification--both the public and
direction notification begins, and then at the end of the
year or the beginning of 2000, we might have sufficient data
to take a preliminary look at it.
DR. SECUNDY: Well, what will you--
DR. ALTER: Okay. What will we be measuring? We
will be specifically measuring the proportion of recipients
identified who are ultimately tested, the proportion of
those tested who are identified as positive, the reasons
persons do not receive notifications, and the reasons
persons, upon being notified, do not get tested. That will
be some of the basic information upon which we will
initially evaluate both approaches.
We will compare them and see if we think one has
had a substantial impact over the other based just on the
differences in the percentage of individuals we can estimate
got tested using both approaches.
CHAIRMAN CAPLAN: Dr. Alter, let me--I said I was
going to take one more question, but you're hitting an area
that's got Dr. AuBuchon and myself ready to ask a question.
I'm going to ask you to be as succinct as possible because
we've got to get over to the FDA testimony. But, quickly,
just two quick questions from me, and then Jim, and then
we'll let you out of there. You've been up there a while.
Do you think it's possible to send out a
notification to these 54,000 people, risking--
DR. ALTER: It's not 54--
CHAIRMAN CAPLAN: --false notification of many
people to find them that won't frighten people? In other
words, is the issue as we look at this gap of the single
antigen testing, can we avoid a panic? Can we avoid undue
distress? Is there a way to reach out to that 'tweener
group as we try to do a lookback without unduly frightening
them, saying you've got a problem, perhaps, but you'd better
come in, or there's a reason for concern? Is the issue
really--
DR. ALTER: Some individuals are going to get
letters like that because there is a certain percentage of
individuals who received blood from donors who came back to
be tested by multiantigen assays where the donor was not
confirmed, and they're included in the guidance issued by
FDA, and that's fine. You know, it does represent a small
percentage, and we have constructed what we think are
reasonable letters to these individuals explaining what this
means.
But you're talking about doing that to 400,000
people or their families, and although I can't predict what
an individual's reactions will be, I can tell you
anecdotally--well, I'd rather not. The Canadians have some
experience with this, but I--
CHAIRMAN CAPLAN: The reason I ask--
DR. ALTER: I don't--you know, it's just our
opinion on whether that letter frightens you or not.
CHAIRMAN CAPLAN: The reason I ask this, in part,
is I'm sitting at an institution that has ties to many
outfits that are proposing to do general population
screening for breast cancer, gene testing for depression,
and they're saying we're going to look at entire ethnic
groups or X, Y, and Z, and they're not hesitating because
the yield will be tiny, much less than what we're talking
about here. They are trying to be careful how they market,
let's say, genetic testing, looking for probability and risk
factors.
So I'm a little--you don't have to answer this.
I'm just watching sort of--
DR. ALTER: But keep in mind that we're not
notifying one group in favor of another.
CHAIRMAN CAPLAN: I understand that.
DR. ALTER: I think that's a very important
principle. We're notifying everyone, but in different ways.
And I don't know that there's really an answer for your
question.
CHAIRMAN CAPLAN: Back-of-the-envelope
calculation, if there's 50,000 people out there in, again,
this 'tweener group who might be benefited by a direct
notification, perhaps might be found as opposed to a general
lookback, general notification, public education campaign,
if we figure that there's $100,000 per head on a liver
transplant and--I don't know--a tenth of them convert to
liver failure and maybe 30 to 40 percent of them could have
been helped by available or emerging therapies, that's a
pretty good chunk of change on the therapy end, forgetting
the education campaign and so on. So if I just do a quick
back-of-the-envelope, I come out with a question that says:
Isn't it cost-effective to find some percentage of those
50,000 if we are now moving toward a position where we could
prevent morbidity and mortality?
DR. ALTER: Dr. Caplan, I appreciate that
perspective. I think, however, that we've been criticized
in the past for even the perception that we might be
considering cost as an issue here. And since cost--if you
want to look at cost-effectiveness, you would also have to
look at the resources required to notify the over 500,000
people or, you know, the almost 500,000 people that would
result in the 50,000 alive getting testing. Okay? Of which
only a small percentage of them would actually get tested.
So it's not that you're identifying 50,000 people who are
alive. Then you have to take into account how many of them
can be found, how many of them will respond to the test--to
the call to be tested, and all of that. And we did not go
into those calculations because we did not feel that that
should be a part of this particular decision.
CHAIRMAN CAPLAN: Jim, you're going to get the
last question.
DR. AuBUCHON: A comment, Mr. Chairman. I just
wanted to take this opportunity to publicly thank the
Centers for Disease Control and Prevention, and particularly
Dr. Alter, for their efforts and for her efforts in making
information available to the blood banking community and
making materials available for us to use in this
notification process.
As a physician in a transfusion service who's
deeply embroiled at the moment in conducting these
notifications, I greatly appreciate having this information
available, Miriam, and I thank you and the CDC for all of
the efforts, because without this information, blood bankers
who are not hepatologists, who are not counselors, who are
not public health experts, would not have the information
that we need to conduct this in the most thorough manner
possible and to have the greatest possible outcome.
Thank you.
DR. ALTER: Thank you, Jim.
CHAIRMAN CAPLAN: Thanks, Dr. Alter.
We're going to watch the time carefully because we
do have--I know that many on the Committee want to ask
questions, and I'm going to ask people to try and keep their
prepared remarks succinct so that they leave time for
questions. Otherwise, Steve will be breaking off various
appendages of mine in unseemly fashion here if we go way off
schedule.
So let's try and keep our prepared formal
presentation as brief as possible because I know the
Committee wants to put questions. Who do we have? Dr.
Mied?
DR. NIGHTINGALE: Yes.
CHAIRMAN CAPLAN: From the FDA.
DR. MIED: Thank you, Dr. Caplan.
I am Paul Mied from the Division of Transfusion
Transmitted Diseases in the Office of Blood in the Center
for Biologics Evaluation and Research, or CBER. I'm going
to summarize the actions taken by FDA to implement HCV
lookback following the statement of a Department position by
Dr. Shalala in January 1998, and I'll focus especially on
the sequence of events that led to the change from the March
guidance to the September guidance:
On September 23, 1998, FDA issued a Revised
Guidance for Industry Document on HCV lookback. The FDA
recommendations contained in this revised guidance document--and I think you'll find this in Tab E--are provided to
enable quarantine and disposition of units from prior
collections from donors with repeatedly reactive screening
tests for anti-HCV. Additionally, FDA recommends that
consignees of certain blood and blood component units
collected since January 1, 1988, which were anti-HCV
negative or untested, be notified when donors subsequently
test repeatedly reactive for anti-HCV in a licensed
multiantigen screening test and reactive in a licensed or
investigational supplemental test. This notification would
enable recipients to be informed that they had been
transfused with units that may have contained HCV so that
they may obtain further medical counseling. This document
was provided on the CBER home page for comment and
implementation on September 23rd and published in the
Federal Register with a notice of availability on October
21st. Additionally, this guidance document was mailed to
all blood establishments on November 20, 1998.
Now, since the comment period never really closes
on guidance documents, comments on the revised guidance will
be evaluated by FDA as they are received and changes made as
warranted.
The September 23rd revised guidance document
replaced the March 20, 1998, Guidance for Industry
supplemental testing and the notification of consignees of
donor test results for anti-HCV, which had undergone major
revision by FDA in response to comments received from the
industry and the public during the 60-day comment period
following its issuance in March.
Now, as a result of these significant changes in
the guidance, FDA made known its intention to reissue
comprehensive guidance on HCV lookback at a public meeting
of the Blood Products Advisory Committee in June 1998, and
these significant changes encompass several major issues.
First of all, due to difficulties surrounding the
availability of the investigational RIBA 3 supplemental
test, the blood banking community requested that the time
frame to complete prospective notification of consignees be
lengthened from within 30 days to within 45 days following
the donor's repeatedly reactive screening test.
Secondly, since the retrospective lookback is
expected to involve an estimated 500,000 components and
difficult lookback situations may be anticipated for some
blood establishments, the blood organizations requested an
extension of the time period to complete the retrospective
lookback from within 18 months to within two years from the
date of the original guidance. The revised guidance states
that consignee notifications should be completed within 18
months of the date of publication of this guidance or by
March 23, 2000, thus providing a full two years from the
date of the original guidance as requested.
The time frame to complete recipient notification
by transfusion services has been clarified. Due to the
large number of notifications which are anticipated,
industry requested that transfusion services be given a year
to carry out notifications of recipients identified in the
retrospective review of records rather than eight weeks, as
provided for prospective notifications.
In the revised guidance, FDA recommends that
prospective notifications be completed within a maximum of
12 weeks and that retrospective notifications be completed
within one year of the date on which the hospital or
transfusion service received notification from the blood
establishment.
The use of an EIA 3.0 test following an
indeterminate RIBA 2 test result is another significant
change.
Now, due to difficulties surrounding the
availability of investigational RIBA 3 kits, the blood
banking community suggested, for RIBA 2 indeterminates, that
the lookback be waived if an EIA 3.0 test is performed and
the result is negative. Data has been obtained to confirm
the validity of this approach, and so the revised guidance
document permits the use of the EIA 3.0 to resolve RIBA 2
indeterminates if the original screen had been performed
with an EIA 2.0.
Now, I'd like to emphasize that the revised
guidance document was ready for CBER clearance when these
changes were completed in July. However, additional
comments and suggestions for changes were received
belatedly. These includes the recommendation that FDA, in
accordance with good guidance practices, incorporate the
previous recommendations on product retrieval from the July
1996 memo to blood establishments. Thus, the revised
guidance document supersedes that memo. This major
revision, which brought the agency's recommendations
regarding the two parts of lookback--product retrieval and
recipient notification--into one comprehensive guidance
document necessitated a major rewrite of the guidance
document in August.
Now, other change which were made following the
June BPAC meeting included the extension of the time frame
for beginning notification of consignees. The March
guidance recommended that notification of consignees
following the retrospective review of records should begin
within six months of publication of the guidance, that is,
by September 20, 1998. The revised guidance states that
blood establishments should begin notification of consignees
as soon as feasible and no later than six months from the
date of issuance of this guidance, that is, the revised
guidance, or by March 23, 1999.
Now, I'll address the need for this extension in
just a moment.
The revised guidance document includes specific
recommendations on labeling of products released from
quarantine for consistency with existing regulations on
product labeling. Flow chart diagrams were also provided to
assist industry in implementing the complex set of
procedures which are specified in the recommendations.
To permit easier, more rapid notification of the
recipient, the blood organizations requested that
establishments be permitted the option of notifying the
patient directly as an alternative to notifying the
patient's physician of record that the patient was
transfused with a unit that potentially contained HCV. The
revised guidance states that when the patient is notified
directly, the physician should be informed concurrently.
Now, in addition, during this time, June through
July, we were quite heavily involved in the process of
drafting a proposed rule on HCV lookback, and the
bureaucratic process of reconciling the proposed rule with
the revised guidance document and getting it cleared through
general counsel was a major accomplishment during this time
period.
The March 20th guidance was withdrawn on September
8th by a notice on the CBER Web site. The revised guidance
was issued on September 23rd, 15 days later. FDA withdrew
the September--excuse me. FDA withdrew the March 20th
guidance so that blood establishments would not be compelled
to implement the previous outdated guidance which
recommended that notification start by September 20, 1998.
And I should point out that the blood industry was aware
that this action did not signal discontinuation of the
lookback initiative.
The reasons we extended the implementation
deadline for consignee notifications to start were, first of
all, that the wholesale changes we had made in the guidance
required time to implement and that such an extension was
necessary to allow time for the physician education to be
completed. The six-month period from the date of issuance
of the revised guidance for blood establishments to begin
notification of consignees was provided to more closely
coincide with the rollout program for physician education,
ensuring that counseling messages would be available for use
in notification of recipients.
Indeed, now that the MMWR recommendations for
prevention and control of HCV infection and HCV-related
chronic disease, which contains guidelines on counseling and
treatment, was issued on October 16, 1998, some of the
larger and independent blood banks are beginning to notify
consignees.
So you can see that the first nine months of this
year has been a period of intense, basically non-stop effort
at FDA in the implementation of HCV lookback, with the
development of the initial guidance document, the revised
guidance document, and rulemaking on HCV lookback. And
FDA's role in HCV lookback implementation is going to
continue.
Here's an outline of FDA's plan with the time
frame for accomplishing each part of that plan.
Now that the revised guidance document has been
published, we will continue to establish policy by guidance
by responding to comments on the revised guidance document
and conducting inspectional surveillance of lookback
activities. We're also going to be assisting other DHHS
components in evaluating the effectiveness of the public
outreach and the targeted lookback programs.
FDA is also committed to establishing requirements
for HCV lookback through the rulemaking process. As I
mentioned, a draft proposed rule is awaiting DHHS and OMB
clearance. FDA will respond to public comments on the
proposed rule, issue a final rule, and conduct oversight of
implementation of HCV lookback procedures by the industry.
Now, with respect to implementation of HCV
lookback by the industry, the time frames for the
retrospective lookback and the revised guidance document
issued on September 23, 1998, are as follows:
Blood establishments should begin notification of
consignees as soon as feasible and within six months from
the date of issuance of the revised guidance, that is, by
March 23, 1999.
Blood establishments should complete all
notifications of consignees within 18 months of the date of
issuance of the revised guidance, that is, by March 23,
2000.
A transfusion service should begin notification of
the recipient when notified by the blood establishment and
should complete all notifications of recipients within one
year following receipt of notification from the blood
establishment, that is, by March 23, 2001, for the last of
the notifications received.
I'm going to shift gears a little bit and share
with you some of the operational experience with HCV
lookback driven by EIA 2.0 and 3.0, that is, what people are
doing now and how effective it's been.
According to AABB, now that the MMWR has been
issued, some of the larger and independent blood banks are
just beginning to notify consignees. The American Red Cross
is preparing to begin notifying consignees. I should point
out that some of the smaller blood banks actually had
started to notify consignees before the MMWR was issued.
Some blood establishments are doing the lookback and the
notifications in stages: first, the RIBA 2 positives, then
RIBA 2 indeterminates, with additional testing as needed.
At the AABB meeting earlier this month, Dr. Mindy
Goldman presented the experience of the Province of Quebec
with HCV lookback. They initiated targeted lookback in
March 1995. Out of 1.75 million donations collected from
March 1990 to March 1997, they identified 561 repeat donors
who were anti-HCV positive. Their prior donations totaled
3,197 components. The information they received from the
consignees on 2,329 of these components was that, for many
of the components, the patient had died or was not
traceable, but that 355 recipients, or 11 percent, were
located and were tested for anti-HCV. Of these, 217, or 61
percent, were positive, and of those, 103, or 47 percent,
learned of their infection for the first time.
Surprisingly, 114, a little more than half,
already had been tested and knew they were positive.
However, in the preceding six months, there had been a lot
of publicity and special education efforts in Canada about
hepatitis C and blood transfusion. So one lesson here is
that public outreach messages do work.
Also, they found more cases than expected. The
yield rate after three and a half years of the lookback
effort was 355, or 11 percent, of the target population that
was tested.
Contrast this with the experience of the blood
center of southeastern Wisconsin as presented at the AABB
meeting by Drs. Becker and McFarland. They initiated
lookback in August 1997 on 304 RIBA 2 positive donations,
which were traceable to 34 repeat donors, with prior
donations made after January 1987 which were not discarded;
319 products from prior collections were identified that
required notification. Information was obtained on 120 of
those components, leading the tracing and notification of 9
recipients, of whom 5, or 56 percent, tested positive. A
comparable percentage to that in the Canadian study.
However, the yield rate of 2.8 percent of tracing
living recipients who were willing to be tested was about
one-fourth of the 11 percent found in the Canadian study.
Now, there currently are evaluations underway to
determine the utility of first-generation EIA lookback,
going back to EIA 1.0 in the targeted lookback effort. The
military and some private sector blood banks have indicated
they are considering doing lookback on EIA 1.0 repeatedly
reactive donors.
Now, there's divided opinion over whether
attempting to locate and recall EIA 1.0 repeatedly reactive
donors is appropriate. Most feel if you have a sample, do a
RIBA to determine whether to notify. I'd like to emphasize
that while there are no outcome data available yet from any
of these efforts.
I'm going to just be summarizing the limited
information that we've been able to obtain so far. You will
see, though, that lookback based on EIA 1.0 is being
approached in a variety of different ways.
The military's experience is that many of their
donors are first-time donors, with no prior donations to go
back and look for, so the number of lookbacks they have to
do is considerably lower compared to the civilian
population. They are doing lookback based on unconfirmed
1.0 repeatedly reactives. They have no supplemental test
results.
Now, the services have been given the option to do
additional testing if they want to, that is, RIBA 2 or RIBA
3 with the Red Cross or EIA 3.0 if they want to, but none of
them have taken that option because they don't have frozen
samples back that far, and it's difficult to call donors
back in for additional testing. Most of their facilities
have begun the retrospective review of records.
The American Red Cross presently intends to do
lookback for EIA 1.0 repeatedly reactives, but only for
those with supplemental test results, investigational RIBA
2. Their projections are that, because of extending the
lookback to first-generation EIA, the number of repeat
donors to do lookback on will increase from 28,000 to
37,000, an increase of about a third; the number of
components will increase from 242,000 to 320,000, an
increase of about a third; and the number of recipients to
be traced and notified will increase from 50,000 to 60,000.
Blood Systems, Inc., of Scottsdale, Arizona, is
doing lookback for all unconfirmed EIA 1.0 repeatedly
reactives. They no longer have stored samples, but they're
searching records and they're sending out letters to
consignees covering 14,000 donations.
The Community Blood Center in Kansas City,
Missouri, has stored samples for their EIA 1.0 repeatedly
reactives, and they are preparing to do consignee
notifications based on EIA 2.0 and RIBA 2 results on those
stored samples. Extending the lookback to first-generation
EIA has nearly doubled the volume of their lookback effort.
If we would attempt to answer the question of what
should be the scope of lookback for HCV, we may be able to
draw on the experience from the Canadian and the Wisconsin
studies I've cited and from previous lookback efforts. One
option that we might discuss would be a lookback effort of
contacting and testing all transfusion recipients.
In the general lookback effort for HIV in the San
Francisco area, the number of persons who could be
recontacted after 6 to 12 months was very low, and only 4.4
percent of the 17,331 persons notified by individual letter
who were transfused during the risk period prior to
screening for HIV actually sought testing.
Now, shortly after anti-HCV kits were licensed in
1990, one blood center initiated a pilot study of general
HCV lookback, a transfusion recipient education program
about hepatitis C. Following the widely publicized, large-scale targeted community education and notification
campaign, a very small proportion, only an estimated 1 to 5
percent, of the transfused population living in the area
were tested, and only 6.2 percent of recipients who actually
sought testing had a positive test result on a supplement
test.
Therefore, based on these two studies, targeted
and general efforts to notify all transfusion recipients
have limitations similar to targeted lookback based on donor
testing.
I think I'll stop there and take any questions you
might have.
CHAIRMAN CAPLAN: Thanks, Dr. Mied.
Let's open the floor up for questions, comments?
MS. O'CONNOR: With the two studies you cited
here, were there any general education efforts that went
along with that?
DR. MIED: I think there certainly was in the Zuck
study, the HCV study. There was a widespread community
education and notification campaign. The first study is Dr.
Busch's study. Maybe he can comment on the scope of the
education that was--
DR. BUSCH: Right. These are two different
formats. The first study involved particularly UCSF, but
also several other regions in the Bay area. The hospitals
searched their transfusion records and sent letters,
individual letters, to all patients who they had information
they had been transfused in the prior risk period. And you
see that only about 5 percent of those letters ended up
triggering recipients to come in and get tested.
The second study did not include specific letters
to recipients. It was exclusively a large general public
education campaign approach with free testing available.
DR. PENNER: No combined?
DR. BUSCH: Right. There was no--to my knowledge,
in the states there's no experience where--I mean, there
was--in addition at the same time San Francisco sent
letters. That was coincident with when CDC put out their
broad recommendation that transfused recipients should be
tested for HIV.
CHAIRMAN CAPLAN: Yes?
DR. GOMPERTS: This is a question for Dr. Mied as
well as Dr. Alter. To what extent has the procedure for
testing been evaluated as a barrier to this overall public
health campaign?
DR. MIED: The procedure for testing?
DR. GOMPERTS: Yes. Where is testing being done?
DR. MIED: Where is testing--testing is being done
by the blood establishments, or oftentimes they will send
samples out and receive back the results.
Are you talking about the donors or the
recipients?
DR. GOMPERTS: I'm talking about recipients.
DR. ALTER: My understanding is that the American
Red Cross and many--I know that the American Red Cross plans
to, in their letter to the recipient, offer testing to them
at whatever each local area sets up as a testing site, free
of charge. That's my understanding. And other blood
centers I think will be varying their approaches, but in the
letter of notification it will tell the recipient where they
can be tested and under, you know, what conditions.
So I don't think that testing, at least for the
targeted recipient, is--is an issue that will be very
clearly stated in their notification letter. In terms of
general notification, these individuals will be told to go
to their regular source of medical care for such testing.
DR. GOMPERTS: Do you see this as a barrier?
DR. ALTER: For people who lack any source of
medical care, it could be. It will be important that our
current programs, such as Medicare and Medicaid, cover this
testing.
DR. GOMPERTS: Can I just ask one additional
question? Any possibility, any thoughts from a point of
view of opening up the HIV testing centers to HCV?
DR. ALTER: In terms of our overall plan for
testing people at high risk for HCV, which would include
transfusion recipients, we have taken a variety of
approaches for testing, including the use of HIV counseling
and testing sites, to provide HCV follow-up as well. I
don't know that those are the best places for people with a
history of transfusion to seek testing. In fact, they might
not--they might be discouraged from seeking testing if that
were the designated place, and one of the areas that we're
working on with state and local health departments is to
establish testing places in which people who fall outside,
you know, high-risk groups for HIV would be comfortable to
be tested, and that's part of the plan that we submitted
last April to the Department.
CHAIRMAN CAPLAN: Dr. AuBuchon?
DR. AuBUCHON: I would just note, without comment
that to my knowledge the last statement from Health Care
Financing Administration was that they had not yet decided
whether or not to require the Medicare carriers to pay for
HCV testing subsequent to notification as part of targeted
lookback.
A question. Can you give us an update on the
status of the licensure, potential licensure of RIBA 3.0?
This supplemental test would correspond to the most
sensitive EIA testing that's available and the one that is
generally used blood-collecting agencies but for which there
is not a corresponding licensed supplemental test.
DR. MIED: I wish I could give you an update.
Unfortunately, I'm not able to do that. We would like to
see the test get licensed. We recognize the benefits of
having it out there, and we hope that licensure can be
accomplished soon.
DR. BUSCH: Paul, just one clarification and then
one issue. The clarification, you reported for Blood
Systems, Incorporated, that they were triggering lookback on
all first-gen repeat reactives, and I know for a fact that
is not correct. Their program is similar to the Red Cross'
proposed program, triggering lookback on first-gen repeat
reactives for which confirmatory data was available and
which were confirmed positive. And that began approximately
a year and a half into screening. So they have confirmatory
data beginning basically when the Chiron (ph) reference lab
opened in July of, I believe, '91.
DR. MIED: I don't know how many samples they do
have prior confirmatory results for. The impression I got
was that it was a very small proportion of the total number
of the 1.0 repeat reactives, and that when they changed
their facility, many of the samples they had that they could
now go back and retest were not stored properly, and they
had to discard them all. So I think you're correct, but
it's probably a small proportion of the total repeat
reactives from 1.0 that they have.
DR. BUSCH: If they have confirmatory, again. So
the only program that's actually proposed to trigger
lookback on repeat reactives in the absence of confirmatory
data is the military program.
The other point is extending the first gen--for
those samples for which one has confirmation on first gen,
extending it to indeterminates I don't think is warranted.
And the numbers that result are dramatically increased. You
nearly double the number of notifications that would be
triggered if you include RIBA 2 indeterminates. And I think
we know, similar to the policies that are currently approved
by FDA, if you have a better confirmatory assay, such as the
third-gen RIBA for second-gen reactives, you're not
requiring notification of indeterminates. And I would think
that same policy could and should apply here. If we have
first-gen repeat reactives and we have second-generation
RIBA, among the second-generation RIBA indeterminates only a
very small fraction would be confirmed positive. I think
that's a group that there's a very, very low probability of
true infection.
DR. MIED: But you're absolutely right, Mike.
Point well taken. There's quite a difference in doing it on
positives versus positives and indeterminates.
CHAIRMAN CAPLAN: Let me try a different line of
questioning to you about speed of lookback and
implementation of policy. Let's see. What are we in?
We're at the end of November. I think the Committee was
hoping at one point that lookback would have started. I
remember a lot of discussion here of not worrying too much
about the pre-'92 group in the hope that we'd be underway.
And I understand, Dr. Mied, that the revisions and reactions
and input from other sources led to the revised rule and
rulemaking as well.
I guess what troubles me a little bit is, as I
look out there and see some lookback campaigns, some are
going to be launched in a different direction, and some are
out there by private companies, which are now able to
directly market things they think might be efficacious, and
you can see a certain kind of education campaign. I've seen
some advertising copy and some ads that have me worried that
the American people will find out that if they're breathing
and have blood they ought to go out and have a hepatitis C
test. I would rather hear that message coming from
government agencies, authoritative sources, physicians,
health care professionals. So that leads me to be nervous
about speed.
The question that I have for you is: Can we be
assured, given that we're in November, that we are going to
start in March, that the timetable will be firm, that we're
not going to see ourselves set back further? I mean, the
context here is not simply one of letting people know about
their risks, about ways to reduce morbidity or harm and
infectivity, but also that as you look on the therapy side,
the ante goes up and messages are going to start to be
coming out from many sources, some of which may--how can I
put this?--have a spin on that message.
So what I'm looking for is some assurance that we
were here once before and we're not looking back yet, and I
know we're getting ready to look back again. I saw the
slide. I understood what the story was. But I'd like to
have some assurance that we won't be sitting here in April
wondering what's up.
DR. MIED: Dr. Caplan, I think that the good news
is that many small blood establishments have begun their
notification process, and no doubt some of them have
completed their notifications. The larger and independent
blood establishments or blood organizations are notifying
consignees now, and I think that our recommendations state
that you don't have to wait until March, that blood
establishments should begin notification of consignees as
soon as feasible, and for many blood establishments, that's
now.
In fact, it has been feasible for them to notify,
and they have done so, but that they complete all
notifications by March 23, 1999, and that's a firm date,
that they begin notifying by that time. So that's a firm
date, and certainly the counseling materials are out there.
CDC has done a wonderful job in getting those out, and now
that they're widely available, you know, I think that that
can proceed and that date is easily accomplishable.
CHAIRMAN CAPLAN: David, I see your--
DR. FEIGAL: I just wanted to comment that I think
as soon as this Committee made its recommendations, even
before Secretary Shalala made her statement, we're aware of
the fact that the blood centers were beginning to identify
the products that needed to be traced. And one of the
things that's difficult to appreciate in terms of the
magnitude of this is the amount of it that's invisible
before the letter goes out.
You saw some of the trees that start with the
millions of units, and then whittle it down to the number of
recipients, and then expand back up to the number of
components. So I think it's that first part that is well
under way.
Some of the comments will adjust some of that, but
I think the industry knew that there were certain people
that were going to be part of the lookback no matter what.
We're arguing about some of the margins. And I think that
process is well under way.
DR. SECUNDY: The congressional report made
comments about the failure--the lack of a monitoring or
enforcement mechanism for FDA relative to the industry and
the lookback. Can you speak to that issue relative to what
you have presented? How are you going to know that it's
being done? What processes exist formally or informally?
DR. MIED: We have inspectional surveillance of
blood establishments. Now that the revised guidance is out
there with its firm dates by which they need to begin
notification and complete notification, our inspectional
surveillance activity of blood establishments will see that
that, in fact, is accomplished.
Once the regulation is out there, then we will
conduct surveillance to see that the regulation is complied
with, not just the guidance. So we have that oversight now
with the guidance by inspections, and we will have it with
the rule when it is published.
DR. GUERRA: A couple of comments. I think, you
know, as we have seen in our own community and in other
communities around at least the State of Texas, the initial
efforts are certainly underway with any number of the blood
centers that have initiated that in their communities and I
think are being very good about trying to be appropriate in
the way they have taken the information to the recipients of
those units where they have identified individuals that have
been positive.
The greater concern for us has been that there is
certainly some lag in reporting to us, at least from a
public health standpoint where we're trying to maintain some
surveillance in the community, and the other is that we are
getting now an increased number of calls from the people
that are worried because they have had some contact with
those that have been found to have received a blood
transfusion from somebody that's hepatitis C positive.
So I think that somehow we have to bring those two
systems together of public health at the local and state
level and the blood center industry.
CHAIRMAN CAPLAN: All right. Thank you, Dr. Mied.
Let's go right into our next presentation. This
is the Interorganizational Task Force on HCV Lookback. It's
the AABB, America's Blood Centers, ARC. I'm not sure who
actually is doing the presentation on this one. All right.
xx DR. TRIULZI: Thank you, Dr. Caplan. Good
morning.
My name is Dr. Darrell Triulzi, and I am an
associate professor of pathology and medicine at the
University of Pittsburgh and medical director of a large
multi-hospital transfusion service in Pittsburgh that
supports the largest liver transplant program in the nation.
Since our transfusion service does account for
two-thirds of all the blood transfused in Pittsburgh, I have
abundant experience in the lookback process for HIV, HTLV,
and CJD, and it is anticipated that our transfusion service
alone will receive a list of more than 3,000 components
implicated in the HCV lookback in its current form.
From this background, as one in the trenches, I'm
speaking to you this morning on behalf of the AABB
Interagency Task Force on HCV Lookback, and I'm thankful to
have the opportunity to speak to you on this important
issue.
Following the recommendation of this Committee to
conduct targeted lookback for recipients of prior components
from donors determined by testing after May of '92 to be HCV
antibody positive, the AABB formed an interagency work force
to coordinate efforts with the health care community. This
task force is comprised of representatives from the American
Association of Blood Banks, America's Blood Centers, the
American Red Cross, and has liaisons with the FDA, CDC, and
HCFA. The task force represents all facets of blood
banking, including blood collection centers and also
hospital transfusion services.
This task force has taken a very active role in
seeing that HCV lookback is effectively implemented and that
state-of-the-art information about HCV is immediately
available not only to blood banks and transfusion services,
but also to physicians and patients.
The Advisory Committee has received updates from
Dr. Jim AuBuchon, who is a member of your Committee, and has
also been provided with a copy of a letter from the AABB to
Representative Shays which discussed some of the task force
activities in detail.
Targeted lookback is a massive endeavor. The time
and effort required by the entire health care community
should not be underestimated. In the Canadian HCV lookback
experience, they reported two hours of physician time and 12
hours of technologist time were necessary to identify the
recipient of each blood component. Three years into the
process in the Canadian experience, they are only one-third
of the way to completion of their HCV notification effort.
There have been several key developments in the
HCV lookback effort in the United States. First, the CDC,
with input from the blood banking and transfusion medicine
community, has developed sample letters for both patients
and physicians and a patient brochure to be used nationwide
in the HCV lookback program. Second, on September 23rd, the
FDA issued a revised comprehensive guidance document. And,
finally, recipients obviously cannot be notified in a
vacuum, and we have worked diligently to provide education
and counseling materials for notifying the physician and the
recipient.
The task force developed a physician script for
use by the notifying physician and also the CDC published an
MMWR on recommendations for prevention and control of
hepatitis C on October 16th. These educational materials
were provided to all AABB members.
HCFA has not yet published guidance for hospitals,
and we remain concerned that the hospital community is not
aware of the significant resources needed to conduct HCV
lookback. Further, HCFA has not acted to ensure
reimbursement for testing of Medicare recipients. A
specific recommendation from this Committee may be helpful
in accomplishing those actions.
Since the publication of the draft FDA guidance
document, blood-collecting agencies have been working
diligently to identify involved donors and work toward
notification of hospitals. We appreciate the FDA's
understanding of the importance of coordinating the patient
notification effort from hospitals and physicians with
public and physician education about the importance of this
effort.
We estimate that the approximately 300,000
components are subject to lookback investigation in the
current form of guidance document. Records for many of
these units have been identified, and consignee letters are
now going out. Now that all the educational pieces have
been provided, including the recent MMWR, we anticipate that
hospital notification of individuals will proceed at a rapid
pace.
We support the concept of recipient notification
and the extension of previous recommendations to include
donations from donors found to be repeat reactive with the
1.0 HCV test who have been subsequently confirmed with RIBA
2.0. New information indicates that there are some blood
banks that do, in fact, have such confirmatory test records,
and this extension will provide useful information to some
individuals.
On the basis of information presented to this
Committee, including the problems associated with false
positive tests, lack of sensitivity, and the Canadian
experience with HCV lookback, we believe that the most
effective way of notifying recipients with repeat reactive
HCV 1.10 and confirmatory test has not been done is the
general notification plan presented by the CDC.
However, if lookback is extended to HCV 1.0, the
Committee should understand it would be impossible to
accomplish the targeted notification of an additional
536,000 individuals within the current time frames and that,
in fact, it would be years.
At the same time, we support the CDC evaluation of
the effectiveness of targeted and general notification and
stand ready to assist in these efforts.
In closing, I would ask that the Committee
consider the following five points to increase the
effectiveness of HCV lookback:
One, that if the Committee elects to recommend HCV
lookback to 1.0, that adequate time be allowed to perform
this task;
That there be licensure of the confirmatory test,
meaning RIBA 3.0, to resolve donor status in regard to
infectivity, so that way we may minimize unnecessary
notification of recipients;
Three, that there be assistance from the Social
Security locator service to find patients so that we may,
indeed, in the shortest time frame possible get notification
to those individuals;
Four, that there be assistance from the state
government, such as Bureau of Vital Statistics, in sharing
information on patient vital status, such as whether they
are alive or dead, so that we don't need to unnecessarily
notify families;
And, five, that there be coverage of testing costs
by HCFA for Medicare and Medicaid patients.
Thank you for the opportunity to speak today. The
Interagency Task Force remains committed to the public
health effort embodied in the HCV targeted lookback and
general education campaigns.
CHAIRMAN CAPLAN: Thank you. That was a paradigm
of succinct presentation.
DR. PENNER: Since there's a reliance on the
Canadian data, as I recall, the Canadians did not use the--or apply ALT elimination of donors prior to their lookback,
and this I think would eliminate a lot of the repeat donors
that would be applying. So I don't know that their data
really is applicable here.
DR. TRIULZI: Okay.
DR. BUSCH: Just to respond to that, it, in fact,
goes the other direction; i.e., that in the States where we
introduced anti-core and ALT, that resulted in deferral of a
large number of infected donors who would have presented and
been found in triggered lookback. So the Canadian program,
in fact, would have a much higher yield because they didn't
defer those doors. They were detected in the context of
first-generation and second-generation screening.
DR. PENNER: What I'm proposing, though, is that
many of those ALT donors that would have been repeat donors
are now excluded, so, therefore, you have a population of
more single donors who are first-time donors.
CAPTAIN RUTHERFORD: Concerning changing the law
to allow us to go to the Social Security Administration, I
know that the DOD has tried unsuccessfully, wants to have
the law changed to allow us to do that. For those of you
who do not know, there is a law written using the Social
Security Administration and the IRS to allow the state
health departments and the District of Columbia and
commonwealths to go to the Social Security Administration.
Well, if your state health department does not sign the MOU,
then you are blocked from going to the Social Security
Administration.
So the law is really written to allow us to do
that, but it neuters us if you do not sign the agreement
from the local health department. So I think it's an
outstanding idea. If we are really sincere on trying to
locate recipients, then this is one way to do it.
CHAIRMAN CAPLAN: We've flagged an issue here that
is near and dear to my heart. Remember the recent debate,
too, that took place when Congress mandated the identifier
number be put forward, and I don't think the American people
understand the public health consequences of not being able
to trace through public records identifier numbers that
face--that challenge people who want to do this kind of
lookback or other similar sorts of public health
interventions. So maybe the Committee will be able to speak
on that in the discussion period later.
I think it's quite possible to protect privacy
without sacrificing public health, but I don't think we've
made a good case about that, and these kinds of things are
obstacles. So I understood what you were asking for about
help in that area.
DR. TRIULZI: Can I just make a comment? That's
especially true, because going back to 1.0, you're talking
about donations between '90 and '92 and may extend back into
the '80s when people have moved two and three times, and
their vital status and their location may be unknown.
DR. AuBUCHON: Dr. Penner's comments about the
inapplicability of the Canadian experience may be true, but
in a different direction related to being able to find
recipients. In the Canadian health care system and also in
Finland, where they have reported a similar experience with
HCV lookback, they have universal health care; they know
where their recipients are; they know where their patients
are; and they provide them free testing and free follow-up
service. So any concerns about insurability would not deter
someone from getting tested. Therefore, the issue of
establishing some system to identify patients over time is
extremely important. Unfortunately, it did not begin 15
years ago in such a way that it would allow us better
probability of finding recipients we're looking for in HCV
targeted lookback.
DR. GILCHER: Darrell, have you considered
recalling the HCV 1.0 donors and retesting them and then
with a 3.0 test? That's what we intend to do, and that
actually will eliminate a lot of the false positives that we
first found.
DR. TRIULZI: Right. Did everybody hear the
question? It was about recalling the donors who were tested
with 1.0.
The blood center that provides us with blood
recalled the donors from the 1992, the 2.0, on. About 20
percent was the response, the ability to recall donors. So
80 percent, you could not get them back. I suspect that
number of 20 percent would be even lower for people who
donated between 1990 and '92.
The other problem is that RIBA 3 is not widely
available to all blood centers in this country, and I think
that's a problem. It's not a licensed test, and there are
availability issues, and that's one of the reasons why we
bring that up to the Committee, that at least having the 3.0
would allow us to resolve as many of these donors as
possible.
DR. GILCHER: My comment is not RIBA 3. My
comment is EIA 3.0.
DR. TRIULZI: That would be widely available. EIA
3.0 could be used to the same intent.
CHAIRMAN CAPLAN: All right. Why don't we push
on? Maybe the thing to do at this point is to take a break.
We can go to the recipient blood group organizations, COTT,
Hemophilia, IDF and so on, after the break. We can also
hear from the American Liver Foundation at that point.
So let's break for 15 minutes and reassemble
pretty promptly at about 10:15.
[Recess.]
CHAIRMAN CAPLAN: We are going to hear next from
representatives of some of the blood recipient
organizations; following them the American Liver Foundation,
Alan Brownstein.
Terry, why don't you launch us?
MR. RICE: Good morning. My name is Terry Rice,
and I'm a member of the Board of Directors at the Committee
of Ten Thousand.
I had a few overheads for us to enjoy today which
would have made my presentation a little longer, but they
ended up in Manhattan somewhere yesterday, and I haven't
gotten them back yet. So I put together a little bit of
what I could recollect my presentation was, and I'll present
it to you today. It'll be shorter, so it's probably better
for everybody.
First, I'd like to thank the Blood Safety and
Availability Committee for inviting us to speak today on the
subject concerning HCV lookback. We are pleased that the
Federal Government and the blood banking industry are
finally taking the initiative and moving to notify those
exposed to hepatitis C through blood transfusions.
The history of HIV and HCV is one of regulatory
failure and industry inaction, an explosive combination that
resulted in the devastating AIDS epidemic in the hemophilia
community, as well as the HCV infection of potentially
hundreds of thousands of American citizens, a history that
is in large part preventable and avoidable. It is from this
perspective that we address the proposed lookback
initiative.
Prior to the availability of early inactivated
factor concentrates and improved donor screening techniques,
virtually all persons with hemophilia were infected with the
hepatitis C virus. While today we may view this as some
historical matter of fact, it still gives me pause to
reflect that this reality emerged within the world's best
medical care delivery system and regulatory structure.
Believe it or not, there was a time when the medical
community and the regulatory structure considered it normal
or acceptable for persons with hemophilia to be infected
with non-A/non-B hepatitis and for the industry to ship
knowingly lot after lot of adulterated product. Simply put,
there may not be another community more devastated by
hepatitis C than the hemophilia community.
Suffice it to say we've experienced the emotional
and physical suffering which accompanies chronic HCV
infection, as well as a sense of abandonment from those
responsible to warn and inform.
Recently, CDC estimates indicate that some 4
million Americans are now infected with HCV, and this number
is growing. HHS has estimated that the yearly total society
cost of hepatitis C approximates $600 million. Since an
estimated one million of these infections are considered a
result of blood and blood product transfusions, it would be
reasonable to rationalize that society is bearing some $150
million in negative externalities from the production
processes of these products. That's not a bad subsidy for
industry. Society seems to have made a substantial down
payment on whatever it may cost to carry out a humane and
ethical lookback initiative.
One might ask why are we here. Why is hepatitis C
lookback important? At the core of a free society is the
right to self-determination. Americans have a right to know
critical medical information that can substantially impact
the quality of life as well as one's longevity. It is
commensurate with an individual's right to informed consent.
Treatment options are available to persons infected with
HCV. Many of these therapies work best if intervention
occurs in the early stages of disease.
Changes in lifestyle, such as eliminating alcohol
intake, can have a positive effect on an infected person's
well-being and disease progression. Americans should be
informed if they are at risk so that they might seek
diagnosis and treatment options. One would hope that we
would try to reach as many people at risk as possible
through the most effective method of communication--direct
notification.
The scope of the current lookback is too limited.
Proponents of this plan want to begin notification with the
introduction of the second-generation HCV antibody test in
1992. This test was not only more sensitive than its
predecessor, but had an increased specificity. It also
coincided with an available confirmatory test to eliminate
more false positives. While supporters advocate saving
these dollars by limiting this lookback, we would be leaving
out a number of Americans who might benefit from this
notification.
We support at the Committee of Ten Thousand
extending the lookback cutoff date to 1990 with the
availability of the first-generation HCV antibody screening
test, as other countries who have already carried out their
HCV lookback initiatives have done. It is estimated that if
we do carry this HCV lookback back to 1990 and the first-generation test, an additional 700,000 persons might be
identifiable as potentially at risk. Although there will be
a number of reductions in that number based on mortality and
perhaps only 10 percent of these individuals still being
alive today, still there may be as many as 50,000 to 70,000
individuals who can benefit from this additional public
health lookback and information for their own personal
health.
Essentially, if the current lookback proceeds with
the 1992 cutoff date, we will limit our availability to
notifying approximately 300,000 of the one million
potentially infected Americans. To coin a phrase, if it's
good enough to screen with, it's good enough to look back
for.
Another troubling exclusion is that users of blood
products which were made from donors who were infected with
HCV have not been included in this lookback. Although I am
troubled by this, I am not surprised. The hemophilia
community is still waiting for an HIV lookback to be carried
out by industry, as we would presume is required by law.
This statute was ignored with respect to blood products
users although it was carried out with respect to whole
blood recipients who had a lookback conducted in the late
'80s.
But in the lookback, users of plasma products,
such as hemophilic factor, we're being expressly exempted.
Decisionmakers have explained that this exemption was based
on good economic cost/benefit considerations. Since all
persons with hemophilia typically have good medical care,
they would already be advised that it's time to be tested,
and there may not be a serious benefit in identifying those
individuals.
I think that from our perspective it just seems
that every time there is a lookback, persons with hemophilia
are excluded. Is it just because we happen to have such a
breadth of infection that we all just assume that we should
be tested? But we think that there is a pattern that's
developing, and we hope that every time there is a lookback
that we're not expressly exempted from that particular
initiative.
Let's not be naive. We feel that industry is--although I'm sure that the leaders in industry want to do
the right, moral, and ethical thing and are probably
committed to notifying as many persons as possible, we have
to realize that in most cases the decisionmaking is led by
legal advice. And that legal advice is going to in most
cases try to restrict the potential exposure and legal
liability that notification processes can create for
organizations.
Therefore, we believe that the leadership for this
entire initiative must rest with and be carried out by the
HHS since we believe that leaving it to industry to take it
upon themselves to conduct this would not be in the best
public interest.
Lastly, I'd like to thank the Committee and the
Secretary for taking the time to address this issue.
Special thanks should be given to Chairman Shays of the
Human Resources Subcommittee for continuing to make this
issue a forefront issue, and I'm sure that there are going
to be many lives not only preserved but enhanced by his
efforts and the efforts of the members of that committee.
Finally, we strongly support the seven
recommendations as published by the Government Reform and
Oversight Committee.
Thank you.
CHAIRMAN CAPLAN: Jan, do you want to go next?
MS. HAMILTON: Good morning. Thank you for
inviting us once again. My name is Jan Hamilton. I'm
Executive Director of the Hemophilia Federation of America.
I'd like to thank the Chairman and Dr. Nightingale and
everyone for allowing us this opportunity.
If Hollywood were having a casting call for a new
superhero to portray the watchman for safety in the blood
industry, they might look no farther than Congressman
Christopher Shays. Congressman Shays has kept his finger on
the pulse of the blood products industry for quite some time
now and usually points out shortcomings of government and
industry in this field with startling clarity and accuracy.
Congressman Shays has once again sounded the
trumpet for concern and, yes, even alarm in the shortcomings
regarding the silent epidemic of hepatitis C infection
posing a threat to the public health in our country.
However, it has seemed to fall on deaf ears in some of our
Federal public health arenas.
The Centers for Disease Control and Prevention
sources tell us that HCV has now spread to an estimated 4
million Americans. Eighty-five percent of those infected
develop chronic liver disease, and about 10 to 20 percent
develop cirrhosis of the liver within about 20 years after
the onset of infection, to say nothing of those who convert
to cancer. Deaths from hepatitis C are amounting to be
8,000 and 10,000 per year in the United States and within a
decade or so should triple, without more effective programs
for prevention and treatment.
In July of 1995, after an almost two-year study,
the Institute of Medicine released a comprehensive report
entitled "HIV and the Blood Supply: An Analysis of Crisis
Decisionmaking." This report doesn't address problems of
hepatitis in our population, but it does address with great
detail and clarity what needed to be done to prevent another
health crisis like the one with which we have become all too
familiar in regards to HIV.
Some of the recommendations that you will find in
this comprehensive report are: establishment by the Public
Health Service of a Blood Safety Council with a Blood Safety
Director, and we know that's been done; a call for other
Federal agencies to understand, support, and respond to
CDC's responsibility to serve as the nation's early-warning
system for threats to the health of the public. Is anyone
listening? The FDA should periodically review important
decisions made when uncertain about the value of key
decision variables. Who is reviewing these HCV decisions?
In response to lookback, the IOM determined that
earlier action on lookback in regards to HIV might have
reduced secondary transmission of HIV. We have to ask if
we're falling into the same trap here.
When issues instructions to regulated entities,
the FDA should specify clearly whether it is demanding
specific compliance with legal requirements or merely
providing advice for careful consideration. The FDA should
tell its advisory committees what it expects from them and
should independently evaluate their agendas and their
performance. The FDA should develop reliable sources of the
information it needs to make decisions about the blood
supply. The FDA should have its own capacity to analyze
this information and predict the effects of regulatory
decisions, and an expert panel should be created to inform
the providers of care and the public about the risks
associated with blood and blood products, about alternatives
to using them, and about treatments that have the support of
the scientific record. And this is all from the IOM report
recommendations.
It is true that only 25 percent of hepatitis C
transmissions occur through the blood supply. However,
attention to these could and would spill over to other areas
of concern, and the educational component can certainly
apply to all.
Additionally, infection in 40 percent of the cases
cannot be attributed to a known risk factor which alerts us
to the fact that there could be another road to transmission
of HCV of which we are unaware. What is it? Where are
these dangers? And why isn't more being done to find these
answers?
Of the some 4 million Americans now infected with
HCV, as previously stated, 85 percent develop chronic liver
diseases and between 10 and 20 percent of those develop
cirrhosis of the liver and up to 10,000 a year will die from
this so-called silent epidemic. Most of those who have been
infected are unaware of their infection. While there is no
vaccine against hepatitis C, there are effectiveness
treatments of which patients should be made aware. Of
course, they must know to be tested for HCV first in order
to avail themselves of treatment.
A look at the time line of discussion and
decisions, or lack thereof, on the part of our government
agencies is frightening at best. In 1996, Congressman
Shays' committee recommended HHS take steps to notify
300,000 or more Americans known to have been infected with
HCV through blood before 1990. To date, this has not been
done. More than two years have passed, and the numbers have
skyrocketed, and now we're told we're up to a million.
On seven occasions between October 31, 1989, and
December 16, 1994, BPAC considered whether patients
receiving HCV-infected units of blood or blood products
should be notified. Even though treatment options were
available, BPAC chose on each occasion not to act.
October 12, 1995, Donna Shalala committed that HCV
lookback notification would be the first issue considered by
this new committee. This issue was reviewed and discussed
two years later, in April and August of 1997. At the August
meeting, the Committee recommended lookback on patients
testing positive on second generation screening, though some
Committee members wanted more.
There was a steady line of Committee and agency
discussion leading to a statement on March 5th by Surgeon
General David Satcher, who announced an HCV lookback and
education plan and stated his intention to reach
"effectively as many people at risk as we can."
March 20, 1998, the FDA responded with publication
of a guidance to industry in the Federal Register
recommending that blood banks identify past donors of blood
who tested positive for HCV on the 1992 second generation
test and notify hospital blood banks and transfusion
services that they should notify either at-risk patients or
their doctors by September 20, 1998, more meetings and more
workshops on plans for education and implementation of
lookback procedures, and then on September 8, 1998, FDA
withdrew the March 20, 1998, guidance for industry and
didn't say anything about another guidance being issued.
The very next day, September 9, 1998, at a hearing
of Congressman Shays' committee, both Acting FDA
Commissioner Michael Friedman and Jay Epstein gave answers
to questions posed by the Congressman regarding the lookback
campaign and at no time indicated that the lookback had been
withdrawn the day before.
Blood collection organizations were notified by
FDA of the impending withdrawal by telephone on August 28,
1998. However, consumer groups were not notified in
advance, and no written notices were sent by the FDA to
blood banking organizations and no written records kept of
these exchanges.
While on September 23, 1998, FDA issued a revised
guidance for industry, current good manufacturing practice
for blood and blood components, the guidance suggests but
does not require that individuals who receive potentially
HCV-infected blood and blood products should be notified by
March 23, 2000.
Of the almost 1.2 million persons who have
received potentially HCV-infected blood or blood products,
only 25 percent would be directly informed with the lookback
program instituted by HHS. Why? Because HHS has decided
the first generation test had a high false positive rate,
even though the sensitivity rate was 84 to 89 percent, while
the second generation test was 92 to 95 percent.
Estimates are that only 22 percent received units
from an individual with a false positive test. This doesn't
seem to be a number significant enough to leave this at-risk
group uninformed.
The CDC has developed a comprehensive, nationally
focused plan for prevention and control of HCV infection
entitled "A Prevention and Control Plan for Hepatitis C
Virus Infection," referred to earlier today. Components
include counseling and testing, professional and public
education, surveillance, epidemiology and laboratory
investigation and evaluation. The plan was submitted to HHS
on April 14, 1998, but was not discussed by HHS's Blood
Safety Committee due to HHS' refusal to commit requested
funds to this CDC program; and since HHS didn't include the
plan in its budget, Congress was never given the opportunity
to review it.
I would like to refer once again to the Institute
of Medicine report, "An Analysis of Crisis Decisionmaking."
This prestigious panel stated that management of a public
health risk requires an evolving process of decisionmaking
under uncertainty. It includes interpretive judgment in the
presence of scientific uncertainty and disagreement about
values. Public health officials must characterize and
estimate the magnitude of the risk which involves
considering both the likelihood that infection might occur
in various circumstances and the costs and benefits
associated with each of the possible uncertain outcomes.
They must also communicate with the public about the risk
and strategies for reducing it.
We at the Hemophilia Federation of America highly
recommend reviewing the pages of the Institute of Medicine
report. Learn from the mistakes of the past. Help us to
protect our citizens from additional risks.
The powers that be need to build energy, obtain
focus, expand the lookback to a more realistic depth, and
increase the educational components several-fold. Take
advantage of all the consumer agencies that wish to be of
assistance in spreading the word. If we join the hands of
government, industry, and consumer advocacy organizations in
providing education and utilize all the resources that are
available, the silence can be removed from this epidemic.
Thank you for listening to our concerns.
CHAIRMAN CAPLAN: Thank you. Let's hold on to
questions until we get all the presentations. Then we'll
come back to the Committee.
Let's see. Don? Don Colburn is up next.
MR. COLBURN: Good morning, everyone. My name is
Don Colburn. I'm a volunteer for the National Hemophilia
Foundation, and I'm pleased to be here before you again.
I wish I was here on a little bit better of a
topic, though, because as I reviewed the material for this
meeting and we looked at our concerns, we have a number of
issues that everyone thinks the hemophilia community is all
wrapped tightly and secure and everything is okay.
We have approximately 25 to 30 percent of people
with hemophilia who are not seen by our hemophilia treatment
centers. They are outside that wrapped system. These folks
may not know--they're usually mild folks with hemophilia or
von Willebrand's disease. If we take a look at those folks
who have been treated with a plasma product or whole blood
product at that point, you're talking about a large number
of people.
There is a real concern we have when we listen to
things that were said this morning. I cannot believe that
it actually takes 14 hours of a tech and a doctor's time to
discover whether or not someone has actually become a
recipient of a transfusion product. I guess my world of
computerization is a little bit better.
There's also some other concerns that we have,
too. I guess the economic concerns I've heard expressed
here, I can understand it, I can agree with. But it strikes
me that it might be a fair task, easier, just to notify
everyone who's received a transfusion and let them be
notified that they need to have a test for hepatitis C.
Now, one of the biggest challenges we have in the
United States is the collection of blood. There are
seminars held constantly on how to increase donors. What a
better way to educate the public and let them know that they
may have been infected and at the same time, when they do
come in for their test, they can be told about the
importance of blood.
We have opportunities here that we don't seize
upon, and when we talk about a disease, one cannot help but
go back to the early 1980s. And I guess all of you are
going to have the opportunity this weekend for probably a
long weekend, and I am certainly not comparing you to this
group, but I would just ask you to draw your own
conclusions. I might ask that you rent "The Band Played On"
and watch the section where the government panel debates
what they should do with HIV. It's kind of scary. We have
read the same type of things for HCV.
Now, the reasons that we were given back then were
a little bit different. Well, we don't know what causes
AIDS. Well, we know what causes hep C. Well, we don't have
any treatment for AIDS. Well, we have treatments for hep C.
You know, there are just some parallels here that
I'll ask you in your wisdom to give stronger consideration
to and not to give consideration to the economic concerns of
those who feel that reaching out and touching past
transfusion recipients is bad to do.
The other thing that I'm concerned about is I
guess I feel very lucky as I approach Thanksgiving because
when I was a youngster, I received a lot of whole blood
transfusions, and based on the statistic I heard this
morning, if you go in a hospital and have a transfusion, you
have a 90 percent chance of being dead in ten years. I feel
very good.
With that, I would just like to encourage the
Committee to go for a more direct approach and insist upon
it, that people be notified, and, you know, let's not worry
about the false negatives. What better gift a person could
have than to be notified you might have a viral disease and
then to receive the information that you don't.
Thank you.
CHAIRMAN CAPLAN: And Miriam O'Day.
MS. O'DAY: Good morning. I'm Miriam O'Day, and
I'm Vice President of the Immune Deficiency Foundation, and
if you'll bear with me, I'll give the overview of the
organization once again.
The primary immunodeficiency diseases are a group
of nearly 80 different disorders that are intrinsic to the
immune system and result in immunodeficiency. Most patients
present clinically with an increased susceptibility to
infection. These infections are marked by unusual severity
and are generally chronic or unremitting, a point especially
relevant to today's discussions since patients with primary
immunodeficiency diseases may suffer severe complications
from liver viral infections such as hepatitis C.
The Immune Deficiency Foundation was founded in
1980 to further education and research into the primary
immunodeficiencies and thereby improve clinical care and
prognosis of these patients. The foundation is comprised of
over 20 chapters and represents nearly 50,000 U.S. patients.
The foundation's medical advisory committee is comprised of
20 leading clinical immunologists who specialize in the care
of patients with primary immunodeficiencies. Their function
is to advise the foundation on its many medical programs and
develop position statements on issues related to the care
and treatment of this disease. It is on behalf of the IDF
medical advisory committee that I'm making today's
statement.
Of the nearly 50,000 U.S. patients who have
primary immunodeficiency diseases, we have estimated from
our survey data that some 20,000 to 30,000 currently receive
IGIV antibody replacement therapy. Since the introduction
of these products, these patients can look forward to a
normal or near-normal life span. However, adverse events
associated with the administration of IGIV have occurred and
have forever changed or ended the lives of some of our
patients.
Most recently, some of our patients have
experienced an outbreak of hepatitis C due to the use of
IGIV. In July 1994, there were 112 reported cases of
hepatitis C, but this was just the first wave within this
community. Because of the lack of surveillance, we do not
yet know how many people were ultimately infected.
This has obviously been a tragedy for the
individual patients, but it's also unfortunate that we have
not learned anything about the management and natural
history of hepatitis C in the vulnerable population. And as
recently as October of 1998, the CDC's MMWR Volume 47
neglected to mention IGIV recipients during the period from
1993 to 1994 as high-risk individuals who should be screened
for HCV, although the MMWR does mention the transmission via
IGIV.
The establishment of a national registry of these
cases would allow for comprehensive surveillance and, thus,
we could learn about the natural history of hepatitis C
within the primary immunodeficiency diseases. Physicians
are currently unable to counsel their patients concerning
the best treatment, relate the disease severity to immune
function, give an estimate of the number of cases who have
needed liver transplantation, or give any results about the
outcome of this procedure and for which patients it proved
the most useful.
A national registry would be the most valuable
scientific resource for physicians who are dealing with the
aftermath of this outbreak and for scientists who want to
learn more about this common disease.
While it is presumed that transmission of
hepatitis C through IGIV is no longer a threat to our
patient population due to additional viral screening and
viral inactivation steps, we should not fail patients who
may be unaware that they have contracted this disease or to
improve the management of those already diagnosed.
In summary, the IDF medical advisory committee
makes the following recommendations:
Number one, the FDA, NIH, or CDC should establish
a sufficient lookback and registry program to determine how
many cases of hepatitis C occurred in the United States in
recipients, both with and without primary immunodeficiency
disease, of intravenou |
