Abstract
We have studied the prevalence of hepatitis C virus (HCV) infection in Rwandan patients with histologically proven liver cirrhosis (LC) or primary hepatocellular carcinoma (HCC). Anti-HCV antibodies were determined by using a second-generation test, with a line immunoassay for structural and non-structural antigens as confirmation. Seventy-nine patients with LC, 26 with HCC, and 54 voluntary blood donors as controls were evaluated. Anti-HCV antibodies were more prevalent in LC patients (48%) and in HCC patients (38%) than in the controls (17%; difference, p = 0.0001 and p = 0.03, respectively). Eighty-four per cent of LC patients and 54% of HCC patients were HBsAg-negative. The prevalence of anti-HCV antibodies was significantly higher for LC and HCC patients who had been in contact with HBV but who had no persistent HBV infection (p < 0.05). We conclude that HCV infection is common in Rwanda and is linked to LC and HCC.
