ABSTRACT
This study was planned to investigate whether the decrease in the hepatitis C virus (HCV) RNA levels at the first week of combined pegylated interferon and ribavirin treatment of naive genotype 1 patients with HCV was predicting sustained virologic response (SVR). Fifty-two patients were enrolled into the study. HCV RNA levels were measured at the baseline, first, fourth, and 12th weeks of treatment. Thirty-four patients achieved SVR, which basal, first week, and fourth week HCV RNA levels were log 5.57, log 3.65, and log 1.92, respectively. Eighteen patients could not achieve SVR, which basal, first week, and fourth week HCV RNA levels were log 6.22, log 5.45, and log 3.84, respectively (P < 0.05). Patients were distributed in 2 groups according to the amount of decrease in HCV RNA levels at the first week as less or more than 1.5 log. There were 20 patients with ≥1.5 log decrease in the HCV RNA levels at the first week. They were named as patients with very rapid virologic response (VRVR). All patients (100%) with VRVR were achieved SVR. In only 14 (44%) of the 32 patients without VRVR, SVR was achieved. In 16 (84%) of the 19 patients with rapid virologic response and 33 (79%) of the 42 patients with early virologic response, SVR was achieved. A ≥1.5 log decrease (VRVR) in HCV RNA levels of patients with HCV at the first week of combined pegylated interferon and ribavirin treatment predicts SVR very strongly.
