Hepatitis C virus infection in chronic liver disease in Bombay.

To find out the prevalence of antibody of hepatitis C virus (anti-HCV) in patients with chronic liver disease in Bombay, sera from 126 patients (93 men, 33 women; aged 9-70 years, mean 39.7) with chronic liver disease (cirrhosis 103, cirrhosis with hepatocellular carcinoma 3, chronic active hepatitis 20) were tested for HBsAg and anti-HCV antibody. HBsAg positive sera were tested for anti-delta antibody and IgM anti-HBc. All the tests were carried out by ELISA. Of 126 patients, 51 (40.5%) were HBsAg positive, 49 (38.8%) alcoholic and 21 (16.6%) anti-HCV positive. The prevalence of anti-HCV in HBsAg positive, alcoholic and cryptogenic (HBV negative and no alcohol) liver disease patients was 13.7%, 14.7% and 20.5% respectively. Of 21 anti-HCV antibody positive patients, 8 (38%) had received blood transfusions previously. HCV is present in 15-20% of patients with chronic liver disease in Bombay.
