A high prevalence of hepatitis G virus (HGV) infection has been noted in patients receiving chronic hemodialysis (HD) therapy, yet the incidence rate and transmission route have rarely been reported. Serum samples from 160 chronically uremic patients in a HD unit were initially collected at the time chronic HD therapy was begun, and thereafter annually in July and, finally, in November 1999. Serum HGV RNA was detected using nested reverse transcription polymerase chain reaction, and HGV E2 antibody was determined using an enzyme immunoassay. Nucleotide sequences of the 5′-noncoding region were studied in the HD patients with HGV viremia. Forty healthy staff members were also enrolled as control subjects. Three of the 40 (7.5%) healthy staff members were positive for HGV RNA or HGV E2 antibodies, in contrast to 40 of the 160 (25%) HD patients, including 14 (8.8%) who were positive for HGV RNA only, 25 (15.6%) who were positive for HGV E2 antibody only, and 1 (0.6%) who had both markers. HGV exposure did not correlate with gender, age, duration of HD therapy, or history of blood transfusions. At least 20 of the 40 (50%) patients with HGV exposure had been infected before the start of chronic HD therapy. Nevertheless, at least nine (22.5%) patients acquired new HGV infections after starting chronic HD therapy, with an incidence rate of ≥2.6% per year. Three patients with newly acquired HGV viremia after HD therapy was started and two with pre-existing HGV viremia before HD therapy was started had the same nucleotide sequences. HGV and HCV infections (with a prevalence of 14.4%) might have been transmitted independently in HD patients. In addition, HGV infection was not found to cause significant elevation of alanine aminotransferase levels in the group exposed to HGV. To conclude, the incidence of new HGV infections was at least 2.6% per year. In addition to transmission through blood transfusion, HGV may have been transmitted nosocomially patient-to-patient within the HD unit. The compliance with standard universal precautions should be carefully re-examined, but it is not necessary to routinely screen for HGV infection among patients on chronic HD.
