Hepatitis C virus (HCV) is transmitted parenterally, and antibody to HCV (antiHCV) is frequently found in patients on hemodialysis. The prevalence of anti-HCV in hemodialysis patients has been reported to range from 1% in the UK [l] to 50% in Brazil [2]. The frequencyofanti-HCVpositivityhas been correlated both to the durationof dialysis and number of blood transfusions received [3]. However, the relative importance of these two possible modesof transmissionis not clear. We have assessed the prevalence of antiHCV (ELISA, second generation, Abbott, Chicago, Ill., USA) in blood donors and patients on hemodialysis with a view to determine the relative importance of blood transfusion and duration of hemodialysis in acquiring anti-HCV. Only repeatedly reactive samples were defined as truly positive. 14,548 blood donors and 94 patients, on hemodialysis for 1-144 months (m), were studied between April and October 1992 (table 1). Anti-HCV was positive in 67/94 (71%) patients. 40/67 (60%) anti-HCV-positive patients and 18/27 (67%) anti-HCV-negative patients received 1-13 blood transfusions (x2 = 0.4, NS). Among the 58 patients who received blood transfusions, there was no difference in the number of blood transfusions received between anti-HCV positive (3.052.2) and anti-HCV negative (2.2k1.4) patients. Anti-HCV positive patients were on dialysis for longer duration (46+37m, MkSD) than anti-HCV negative patients (22+22 m) t = 3.7, p<O.Ol. 35/67 (52%) had elevation of ALT and positive anti-HCV while only 3127 (11%) had elevation of ALTin the absence of anti-HCV (x’= 13.5; p<O.Ol). Gamma globulin levels were similar in antiHCV positive (32+6 g/l) and negative (31k5 g/l) patients. The prevalence of anti-HCV found in our patients on hemodialysis is the highest reported. Several factors may have contributed to the high seroprevalence. Some patients may have acquired anti-HCV through blood transfusions. The seroprevalence among blood donors in Kuwait was found to be 2.4%, which is higher than in Europe and the USA. However, since the receipt of blood transfusions was not correlated to seroprevalence of anti-HCV, other factors must have been more important. Furthermore, 40% of the anti-HCV positive patients had never received blood transfusion. Patients who were anti-HCV positive were on hemodialysis for significantly longer period than patients who
