[Case-control study of hepatitis C HBs Ag and antivirus antibodies in chronic hepatopathies]. / Etude de l'antigène HBs et des anticorps antivirus de l'hépatite C au cours des hépatopathies chroniques.

The aim of this study is to establish the prevalence of hepatitis C HBs Ag and of anti-virus antibodies in chronic hepatopathies. The prospective case-control study was carried out on 91 patients who needed to be treated for chronic hepatopathies and 92 occasional blood donors. The search for hepatitis C HBs Ag and anti-virus antibodies was done using third generation ELISA screening. At the end of the study, HBs Ag was found in 54% of the patients vs. 4.3% of the control (p=0.0006). The two markers were present more frequently in cirrhosis than in hepatocellular carcinoma (HCC) and their association was more frequent in the case of cirrhosis. In Mali, hepatitis B and C viruses play an important part in chronic hepatopathies.
