ABSTRACT
The antiviral and immunomodulatory effects of interferon were assessed in the treatment of chronic Hepatitis C in multi-ethnic patients to prevent viral replication and chronic liver damage. Three million units of recombinant interferon alpha-2b were administered three times a week for 48 weeks to a group of 9 active Hepatitis C patients. A clinical response was defined as normalization of serum ALT values. Serum was frozen and stored for Hepatitis C viral assays. Four patients normalized their liver functions. When viral levels were measured only two patients had unmeasurable levels of HCV RNA after treatment. Therapeutic results were observed and much work needs to be done to improve therapy because a serious epidemic is predicted for the future.

The antiviral and immunomodulatory effects of interferon were assessed in the treatment of chronic hepatitis B in multi-ethnic patients to prevent viral replication and chronic liver damage. Five million units of recombinant interferon alpha-2b were administered three times a week for 48 weeks to a group of 18 chronic active hepatitis B patients. A complete response was defined as seroconversion to anti-HBe and/or loss of HBe antigen. Seroconversion to anti-HBe in 5 of 12 (42%) chronic active hepatitis B patients occurred after 48 weeks of therapy. HBV-DNA decreased to undetectable levels in 8 of 12 (67%) patients. This chronic low-dose interferon administration regimen demonstrated responses comparable to other studies.
