Abstract
Background/Aim: To evaluate the utility of early testing for hepatitis C viremia as a predictor of treatment outcome during interferon or combination therapy. Methods: We studied 184 patients with chronic hepatitis C who received interferon and were monitored for HCV RNA. Sixty-two patients received interferon alone for 12 months and 122 patients, who were still HCV RNA positive at 2 months, received an additional 12-month course of interferon and ribavirin combination therapy. Results: Using this strategy, sustained response occurred in a total of 34 patients (18.5%). Independent variables associated with sustained response were HCV genotype ( p=0.06), viral load ≤5.1 logs/ml ( p= 0.005) and negative HCV RNA at 1 month ( p<0.0001) in the interferon group, and female sex ( p=0.04), genotype ( p=0.03), viral load ≤5.5 logs/ml ( p=0.01), normal ALT ( p=0.001) and decline in viral load ≥1.2 logs/ml after 2 months of interferon monotherapy ( p<0.001) and negative viremia at 5 months of ribavirin onset ( p<0.0001) in the combination therapy group. Persistence of viremia at 1 month of interferon monotherapy and at 5 months of combination therapy were the strongest predictors of non-response (negative predictive value of 100% and 99%, respectively). Conclusions: Qualitative assessment of HCV RNA during treatment is the strongest predictor of sustained response during interferon or combination therapy for chronic hepatitis C.
