Treatment of anicteric acute hepatitis C with peginterferon alpha-2a plus ribavirin

Abstract

Background. Hepatitis C virus (HCV) infection is the most frequent cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma in the world. Acute hepatitis C is the most commonly asymptomatic liver disease with the development of chronic HCV infection in the majority of infected patients. Studies of the natural history of HCV infection suggest that only 15-30% of patients with acute infection recover spontaneously. Others, up to 85% of the infected patients develop chronic hepatitis C. Acute hepatitis C is so uncommon and with the unpredictable occurrence, and of the low frequency, that it is difficult to determine the optimal treatment of this disease. There have been many randomized, controlled trials of the therapy in patients with chronic hepatitis C, but none of an adequate size or rigor in patients with acute hepatitis C. Therefore, the causal treatment of patients with acute hepatitis C aimed at the prevention of chronic liver disease is necessary. Case report. We have treated a patient with anicteric form of acute hepatitis C after a three-month outpatient follow-up using a combined therapy: pegylated interferon-alpha 2a, 180 μg, subcutaneously, once a week plus ribavirin 1000 mg orally once a day. The treatment lasted 24 weeks. Stable biochemical and virological response was achieved both at the end of the treatment and 6 months after the completion of the therapy. Conclusion. We believe that the above mentioned might be one of the approaches to the treatment of acute hepatitis C. However, further prospective studies with significantly larges number of patients are necessary for the definite conclusions about the treatment of HCV infections.
