Risk Not Limited to Injection Drug Users
A study in New York City has found a higher than
expected prevalence of hepatitis C infection among
non-injecting drug users. In this study, as many as 17
percent of the subjects who denied a history of injection
drug use were found to be infected, compared to a 2
percent infection rate in the general population. Among
women from one of the study sites in East Harlem who
reported use of non-injection heroin, the rate of
infection was as high as 26 percent. The findings,
published in the May 1 issue of Substance Use &
Misuse, may indicate that use of needles and syringes is
not the only drug-related risk factor for Hepatitis C Virus. Currently,
about 60 percent of all new cases of Hepatitis C Virus infection in the
U.S. are attributable to syringe and needle-sharing with
an infected individual. Dr. Alan I. Leshner, National
Institute on Drug Abuse (NIDA) Director, says this study
demonstrates that "We need to look closer for other
routes of Hepatitis C Virus transmission among non-injecting drug-users.
If hepatitis C can be transmitted through the sharing of
non-injecting drug paraphernalia such as straws or pipes,
we need to include this information in public health
messages targeted to this population."

Augments Effect of Interferon in Clearing Hepatitis C
Virus
(Philadelphia) – In a study involving previously
untreated patients with chronic hepatitis C, the
combination of histamine dihydrochloride (Ceplene™
Injection, Maxim Pharmaceuticals, San Diego, CA) plus
interferon-alfa-2b (IFN) produced a sustained viral
response that was approximately twice that usually seen
with IFN alone. This phase 2 study tested various doses of
histamine plus a fixed dose of interferon for 48 weeks.
Results at 72 weeks (24 weeks after the end of therapy)
showed a sustained viral response in 40% of evaluable
patients in all four histamine dosage groups combined. At
the highest dose of histamine–10 milligrams per
week–44% of the patients had a sustained viral response.
These results compare favorably to the 16% sustained
complete response at 72 weeks commonly observed for
patients treated with IFN alone. The results were
presented this week at the meeting of the European
Association for the Study of the Liver (EASL) in Prague,
Czech Republic. “The end-of-study results presented
today suggest that histamine… contributed to a much
higher rate of sustained response in patients infected
with hepatitis C,” said Yoav Lurie, M.D., principal
investigator in the study and Liver Clinic Director,
Kaplan Medical Center, Rehovot, Israel. In addition, he
said, “During the initial 12 weeks of the study we saw a
substantially higher percentage of rapid responders to
combination therapy with [histamine] than would be
expected under treatment with interferon alone."
- April 4, 2001 -- Tattooing
A Major Route Of Hepatitis C Infection
Getting a tattoo could be a key infection route for
hepatitis C, the most common chronic viral infection
affecting almost 2 percent of the United States
population, according to a study by a UT Southwestern
Medical Center at Dallas researcher. Dr. Robert Haley,
chief of epidemiology, writes in the March issue of the
journal Medicine that tattooing has been previously
overlooked as a widespread source of hepatitis C, a
potentially fatal disease that attacks the liver, leading
to cirrhosis and liver cancer. The study found that people
who had received a tattoo in a commercial tattoo parlor
were nine times more likely to be infected with hepatitis
C than people who did not have a tattoo.
