In order to evaluate the incidence of hepatitis C virus (HCV) infection in haemodialysis, we studied the population of three dialysis units without segregation of anti-HCV positive patients. An anti-HCV test (2nd generation Elisa) was prospectively performed on 88 patients on RDT every 4 months from April 1991 to October 1994. Second generation Riba and HCV-RNA by PCR were used in positive subjects. General precautions, as in Center for Disease Control Recommendations, were applied in avoiding nosocomial transmission, but no special measure was set up. Mean follow-up was 37.2 months. Anti-HCV Ab were initially detected in 32 (35.2%) patients; during the follow-up HCV seroconversion was observed in 1 of 56 (1.7%), 2 of 55 (3.6%) and 2 of 53 (3.7%): thus the mean incidence in the follow-up period was 2.79% years. All seroconverted patients were HCV-RNA positive and 4/5 had a Riba positive test. 3/5 were dialyzed on the same monitor of anti-HCV positive subjects, one was transfused 15 months before seroconversion and one was dialyzed next to a positive patient. Despite a high prevalence of HCV infection, general precautions without segregation showed a fairly good efficacy in limiting nosocomial HCV transmission. Seroconversion seems to be either horizontal, patient-patient, and vertical, through monitors. Simple measure, such as monitors' disinfection after each dialysis session, may improve these results.
