[Studies on hepatitis C virus infection in haemodialysis patients].
To examine the prevalence of hepatitis C virus (HCV) in haemodialysis patients without blood transfusion in Hiroshima Prefecture, antibody to HCV (anti-HCV) was studied by the Ortho ELISA Kit in sera from 393 consecutive haemodialysis patients and in sera from 510 age and sex matched healthy members of the general population (control). An additional confirmatory test was done by a recombinant immunoblot assay. 1) Anti-HCV was detected in 70 of the 393 dialysis patients and 3 of the 510 healthy controls (17.8% vs 0.6%, p less than 0.01). Prevalence of anti-HCV in haemodialysis patients sera was increased by the volume of blood transfusion, and even in dialysis patients who had no blood transfusion, the frequency of anti-HCV positivity (9.2%) was greater than the healthy controls (p less than 0.01). Thus, the major route of HCV transmission in haemodialysis patients without blood transfusion may be via the haemodialysis treatment. 2) The prevalence of anti-HCV increased significantly with the ALT level and abnormal ALT activity of the anti-HCV positive group were significantly greater than that of the negative group. Thus, it is suggested that HCV infection may be an etiologic factor of liver dysfunction in haemodialysis patients.
