    Abstract:
    We assessed the prevalence of anti-hepatitis C virus (anti-HCV) antibodies and markers of hepatitis B virus (HBV) infection in patients of three haemodialysis centres before initiating anti-HBV vaccinations. Of the 94 patients, 39 (41.5%) were anti-HCV positive (+) and 81 (86.2%) were anti-hepatitis B core antigen (HBc) positive. There was a high rate of anti-HBc positivity among anti-HCV (+) patients (92.3%), although the presence of anti-HCV and anti-HBc antibodies were not significantly related to each other. Multiple blood transfusions (> 5 units) was a risk factor for development of HCV infection (P < 0.02), while none of our patients admitted intravenous drug abuse. Although 53.8% of anti-HCV (+) patients have had moderate serum alanine aminotransferase (ALT) elevations during the study period, none has had considerable liver disease, nor did the increased ALT correlate with the presence of anti-HCV. Only two of 17 staff members participating in the survey were anti-HCV (+), though almost every one gave a history of accidental needlestick exposure. All the study subjects were human immunodeficiency virus (HIV) negative. Our results, obtained with the second-generation, highly specific enzyme immunoassay and verified by the immunoblot assay for anti-HCV antibodies, support a recent suggestion that earlier reports might have underestimated the true prevalence of anti-HCV antibodies in haemodialysis patients.
