title: Effects of interferon therapy in "non responder" patients with chronic hepatitis C.
abstract: We reviewed the impact of interferon treatment on viral load, transaminase serum activity and histological features in patients with chronic hepatitis C in whom treatment did not result in a sustained virus eradication. As patients with cirrhosis are often called non responders, we also reviewed the impact of interferon on these end points as well as on hepatocellular carcinoma incidence and survival. This overview provides evidence that interferon in patients who have not cleared hepatitis C virus (HCV) significantly reduces viral load, serum ALT activity, improves histological activity and blocks progression of fibrosis compared to the natural history of the disease. Thus, patients who still have a positive HCV PCR should no longer be called non responders to interferon. Although the number of randomized trials is limited, there is also cumulative data suggesting that interferon could reduce the incidence of hepatocellular carcinoma incidence and mortality.
