title: The follow-up of the efficacy of antiviral therapy at patients with chronic hepatitis C.
abstract: Hepatitis C virus infection can cause progressive liver injury and lead to fibrosis and eventually cirrhosis. Peginterferon alfa-2a represents a significant advance in the treatment of patients with chronic hepatitis C. The aim of the study was to investigate the efficacy, safety and tolerability of the therapy with Peginterferon alfa-2a plus Ribavirin in patients with chronic hepatitis C. The study was made on a number of 37 patients with chronic hepatitis C, admitted in Medical Clinic no. 1, Emergency County Hospital Craiova. The diagnosis of chronic hepatitis was established by means of clinical, biological and morphological investigations. Patients received 180 mug subcutaneously of Pegasys, once weekly, along with either 1000 or 1200 mg/day of Copegus, depending on their weight, for 48 weeks, with 24 weeks of treatment -- free follow-up. We evaluated: sustained virological response, histological response and adverse events. All patients were monitored using blood tests, control of viremia and liver functional tests. Analysis viral response revealed that 11 patients (29.72%) achieved sustained virological response. Histological response was obtained in 20 cases (54.05%) with chronic hepatitis C. The adverse events for Pegasys and Copegus combination therapy were reported in 21 cases (56.72%). Antiviral therapy had positive effect on subjective symptoms in almost half of patients included in our study. An improvement of liver functional tests was noted in the most cases. A third of patients who received Peginterferon alfa-2a plus Ribavirin had sustained virological response. Histological response was noted both at patients with sustained virological response and with unsustained virological response. The side effects of the antiviral treatment are frequent and the severe ones, which require dose reduction, are present at a low number of patients.
