Hepatitis C
Growing chorus of concern over the ‘silent’ epidemic

Nearly 25 years have passed since Paul McVetty, now 44,
roamed the streets of San Francisco, shooting drugs, sharing
needles, embracing havoc with fellow runaways.
McVetty hit bottom, got clean, got married, launched a
career in the gourmet coffee business and moved to Marin
County. The wild times, it seemed, had left no scars.
Until now.
McVetty is in the final stages of liver disease, a
victim of the quiet rampage of hepatitis C: a devilish
blood-borne virus that infects an estimated 4 million people
nationwide—four times the number of Americans infected with
the AIDS virus.
Although hepatitis C is hardly as fearsome a killer as
HIV, it cuts a much broader swath. Intravenous drug users are
its primary victims, but it has also hit such celebrities as
singer Naomi Judd and actor Larry Hagman. Baseball great
Mickey Mantle died of cancer after liver failure attributed to
both alcohol and Hepatitis C Virus, as it is known.
So quietly does the virus take its toll, it has long
been called "the silent epidemic." But the number of
deaths from Hepatitis C Virus is expected to triple within the next 10
years. And as the death count rises, so have the voices of
people like McVetty, one among thousands of recent recruits in
a swelling grassroots movement. The volume can only increase:
- One in every 65 Americans
harbors Hepatitis C Virus, which is spread through contact with infected
blood. Hepatitis C is the No. 1 cause of liver failure
leading to transplant; it is also a significant factor in
liver cancer and big trouble for those also infected with
HIV or the other hepatitis viruses, A and B.
- Officials in charge of the
nation’s blood supply have been sending alerts this year
to some of the 300,000 Americans who may have received Hepatitis C Virus-tainted
blood transfusions before 1992, when the first effective
screens against the virus were implemented.
- At least one class action
lawsuit is in the works amid complaints that the blood
supply warnings should have been sounded years ago.
- Hepatitis C Virus-related legislation has
been introduced everywhere from Washington, D.C., to state
capitols and city halls—including Sacramento and San
Francisco. Measures typically call for more government-led
research and public education, but big money has not been
forthcoming.
- Although Hepatitis C Virus infections can
be treated, drugs are expensive, difficult to take and
help fewer than half of all patients.
- There’s no cure in sight.
"It’s a very dangerous virus," said state
Senator Richard Polanco, D-Los Angeles, sponsor of a
California measure, SB 694, that would direct state health
officials to set up Hepatitis C Virus-education programs. Against this
backdrop, doctors are reeling from an onslaught of public
concern, which they say has been veering dangerously close to
panic in recent months.
"It’s unbelievable," said Dr. Teresa Wright,
chief of gastroenterology at the San Francisco Veterans
Affairs Medical Center, where a large number of patients test
positive for Hepatitis C Virus. "I feel as if there’s a tsunami wave
about to land on my head."
One expert, Dr. Leonard Seeff, senior scientist at the
National Institutes of Health in Bethesda, Md., is calling for
a step back from "mass hysteria."
"I don’t believe for one moment that this is a
benign disease," Seeff said. "But my concern is, we
are going to provoke an enormous amount of potentially
unwarranted anxiety."
Many organizers in the hepatitis C movement agree.
"We don’t need hype," said Ron Duffy, 46, a
substance-abuse counselor in Oakland who contracted Hepatitis C Virus from a
1972 transfusion while serving in Vietnam, and who now needs a
liver transplant.
What activists say they do need, however, is troop
strength. And they’re getting it.
"People are finally waking up," said Brian D.
Klein, 40, an Hepatitis C Virus carrier helping to organize the fledgling
Hepatitis C Action and Advocacy Coalition, a group based in
San Francisco and inspired by the success of AIDS
organizations such as ACT UP. The group plans to protest what
members call price-gouging by the pharmaceutical industry.
In California alone, at least 40 patient-advocacy and
support groups have sprung up in recent years; group leaders
hope to forge a statewide coalition. Duffy, who in 1995
founded the Hepatitis C Virus Global Foundation in Oakland, expects to draw
about 1,000 people to a hepatitis C conference August 23-25 at
the Oakland Marriott City Center.
By all accounts, the state, with about half a million
Hepatitis C Virus carriers, is at the forefront of the grassroots response
to the disease. "It’s the next big epidemic," said
Bill Remak, a recent liver- transplant recipient and
coordinator of a Marin County support group sponsored by the
American Liver Foundation. "Every month, it seems a new
support group is starting up somewhere."
For years, hepatitis C did not even have a name. It was
known only as "non-A, non-B" hepatitis until the
late 1980s, when scientists at Chiron Corp., in Emeryville,
and the Centers for Disease Control and Prevention in Atlanta
managed to clone the virus.
Detectable only through antibody and genetic tests,
"hepC" was discovered to be a fast-changing
"survival machine," as one researcher called it.
Some people’s immune systems kill the virus. But an
estimated 85 percent of those exposed to Hepatitis C Virus become
chronically infected—almost invariably from a contaminated
needle or long ago blood transfusion. Over a 20-year period,
about 20 percent of the chronically infected develop
cirrhosis, scarring of the liver that can lead to liver
failure. A smaller number, perhaps 1 to 2 percent of those
infected, develop liver cancer. The rest die of something
unrelated.
People can contract Hepatitis C Virus from microscopic flecks of blood
left on a communal straw used for snorting cocaine. The virus
can linger on razors and toothbrushes.
It’s been found in small quantities in semen and other
body fluids besides blood, although most researchers say
it’s difficult to transmit through sexual activity unless
there’s blood contact: a possibility from rough sex, anal
intercourse or sex during menstruation or herpes outbreaks.
The only treatments available are the drug interferon, which
often has debilitating side effects, and an anti-viral called
ribavirin, recently approved for use in combination with
interferon. The treatments are costly—at least $700 a month
for interferon alone, and up to $1,440 a month for the
combination. Treatments often manage to quell the virus, but
it returns in the majority of patients. The overall success
rate for the new state-of-the-art combination therapy,
marketed by Schering-Plough Corp., under the brand name
Rebetron, is only about 45 percent.
Nor is there any vaccine for hepatitis C, as there is
for the other main viral culprits in liver disease, hepatitis
A and B. Chiron scientists are in the early stages of testing
one vaccine candidate, but Michael Houghton, the company’s
top Hepatitis C Virus expert, and one of the discoverers of the virus,
cautioned against getting hopes too high.
In the meantime, most carriers are not aware they harbor
the virus: symptoms typically do not appear for years, even
decades, while the microbe quietly destroys the liver.
It is this insidiousness—and the vast numbers of
people carrying Hepatitis C Virus --that has health experts concerned.
Up to 90 percent of intravenous drug users, for example,
test positive for the virus. Hepatitis C Virus infects close to half of the
California state prison population. The chance of contracting
it from a single accidental needle-stick is as high as 1 in
10, far worse odds than contracting HIV, making it one of the
biggest occupational threats faced by health-care and
emergency workers.
In San Francisco, the AIDS virus is still a worse health
problem by far. It infects about twice as many people as the
13,000 estimated to carry Hepatitis C Virus. But deaths from hepatitis C are
rising while AIDS deaths are in decline throughout the United
States. Coinfections are increasingly common. "These are
both health crises, and Hepatitis C Virus is now becoming a major public
health threat," said Supervisor Gavin Newsom, sponsor of
a San Francisco resolution that directs local public-health
officials to devise a plan to deal with the growing crisis.
"We need to be much more aggressive in reaching out to
people who might be affected," Newsom said. That
sentiment was also expressed by former Surgeon General C.
Everett Koop, who during recent congressional testimony warned
of a surge in liver disease for which the medical
establishment is woefully unprepared. "We are at the edge
of a very significant public health challenge," said Koop,
who called for a high-profile public-education effort and
coordinated federal attack. The response so far has been
disappointing, activists say. Leaders of frontline
organizations like the American Liver Foundation are lobbying
for a $56 million increase this year in the $46 million
National Institutes of Health budget for hepatitis A, B and C
research. Other organizers are directing their energies at
persuading more people likely to carry the virus to get tested
for Hepatitis C Virus, both to limit spread of the disease and improve their
chances with drug treatments, ineffective though they may be.
If they hadn’t been pressured, meanwhile, federal
authorities might never have started the "lookback"
study, in which local blood banks around the country are
digging through donor records and attempting to notify anyone
who might have received tainted blood in long-ago
transfusions. The effort marks the first time authorities have
gone out looking for those who may be infected.
Blood Centers of the Pacific in San Francisco, for
example, which provides blood to 35 hospitals in Northern
California, was able to identify about 400 possibly
contaminated units of blood.
Dr. Nora Hirschler, the blood bank’s medical director,
defends the seemingly long time it took health authorities to
send out the notices. For one thing, she said, it was not
clear that much could be done, since there are no surefire
treatments for the disease.
"Before you embark on something like this, you need
to be sure you can do something to help people," she
said.
Such rationales do not wash with those warring in the
trenches. "People should have been notified long ago that
they may be a walking time bomb," said Carol Craig, an
Orange County organizer who believes she became infected with
Hepatitis C Virus while working as a medical assistant. She noted that virus
carriers may be unwittingly infecting members of their family
by such innocuous behavior as sharing razors with teenage
children or having sex during menstrual periods, although
statistics suggest the risk of household transmission is not
very high.
"It’s hard to be urgent without being shrill, but
right now we need to make a strong and urgent point about this
disease," she said. For many years, Hepatitis C Virus inspired little
urgency. The disease moved too slowly. It did damage too
discretely. It affected too wide a populace: People who did
not easily coalesce into a social movement. By comparison,
contracting HIV was almost immediately seen as a virtual death
sentence. Healthy young people became wasted shells. The
disease devastated a politically active gay community.
Now, the Hepatitis C Virus picture is similarly finding focus. A vast
group of carriers contracted the virus in the freewheeling
‘60s and early ‘70s, when it was unknown and the culture
fostered high-risk behavior. "Those are the people now
beginning to get ill," said Alan P. Brownstein, president
of the American Liver Foundation. "Those are the people
dying, and given the vast reservoir of carriers, more and more
people are going to die unless something is done now."
Which is why so many people, from still-healthy carriers
to those near death, are joining the Hepatitis C Virus movement. Like
McVetty, who four years ago began reeling from depression and
fatigue that his doctors could not explain, they now know what
they have: a war on their hands. "We need to get out
there and fight," said Alan Franciscus, 49, a leader of
the HepC Support Project in San Francisco. "Because
nothing’s going to happen if we don’t."
