Abstract

To determinate the viral variables (viremia and genotype) and patients variables (route and years of infection, histology, etc) related with response to the treatment with alpha intefferon in patients with chronic hepatitis C. We have studied 50 patients with chronic hepatitis C that received an intefferon treatment during a year. In all them it was accomplished a hepatic biopsy before of the beginning of treatment and it was studied the viral load by quantitative PCR (Monitor, Roche) at the beginning of treatment, at four weeks and at the end of treatment. It was determined the HCV genotype by method INNO-LIPA (Boehringer Inghelheim). 8 patients (16%) achieved a complete sustained response during all the follow-up period (13.8 + 1.6 months); 8 patients responded but relapsed when the intefferon was interrupted and 34 patients not responded. The responders had lower viremia (p < 0.032) and HCV RNA negative at the fourth treatment week (p < 0.0082). The genotype 1b was the most frequent, the one which was presenting a smaller percentage of response and it was associated with a higher viremia. Cirrhotic patients were the worse responders. Ex-lDAs were better responders than the others groups, however this difference did not show ...Continue Reading
