Should you take maintenance interferon if you are a
nonresponder?
More than half of American patients treated for hepatitis C do
not respond to any antiviral therapy. They have
a partial fall in their HCV-RNA that is temporary. We cannot
cure the infection in these patients using current
therapy. Many years ago, Dr. Mitchell Shiffman
proposed that some nonresponders obtain

from interferon even without viral eradication. This led to
the
.
This large study sponsored by
the NIH was reported at AASLD 2007. It did not show any survival benefit from
maintenance interferon. This was
a large multicenter trial that was designed by excellent
hepatologists. Since the risk of death, liver cancer and
liver failure was the same whether a patient was given
maintenance interferon or not, very few nonresponders
will choose this treatment. Instead, they will wait for new
drugs to be available.
Another trial called
has reported similar findings.I presented
at EASL on 4/14/2005. My data was from patients at the Louisville VAMC. The
patients who achieved sustained viral response had excellent
survival, even those with liver failure. The
patients who did not achieve sustained viral response had poor
survival. Patients with a temporary response
had no survival benefit. There was no survival benefit to
patients who had received more interferon compared
with those who received less interferon. My VA data shows that
if you cure the infection you improve survival
and treatment without cure does not help survival at all.
My current thoughts on maintenance interferon are that nonresponders
with cirrhosis should make certain
that they have tried everything FDA approved to attempt cure, specifically Pegasys, Infergen 15 mcg daily, and
PegIntron. Many of my patients have failed all three of these medicines.
I hope that HCV protease inhibitors
and other new drugs will cure these patients.
