Background. Prevalence and pathogenicity of hepatitis G virus infection in long-term renal transplant recipients, are not fully known. Aim. To evaluate long-term impact of HGV infection on liver disease of renal transplanted patients. Patients and Methods. A total of 155 hepatitis B surface antigen negative kidney transplant recipients, followed for a mean of 11 years after renal transplantation, were studied. Of these 48 (31%) patients had persistently elevated serum aminotransferase values. Frozen serum samples were tested for HGV-RNA and HCV-RNA by nested reverse transcribed polymerase chain reaction, and for anti-hepatitis G virus and anti-hepatitis C virus by enzyme-linked immunosorbent assay. Hepatitis C virus-RNA was typed by a line probe assay and quantified by a branched DNA signal amplification assay. Results. Hepatitis G virus-RNA was detected in 37 (24%) patients and anti-hepatitis G virus in another 26 (17%). Seventy (45%) patients had serum anti-hepatitis C virus and 63 of these (90%) had serum hepatitis C virus-RNA. Hepatitis G virus-RNA positive and negative patients were similar in terms of age, sex, duration of dialysis, rate of transfusion, chronic liver disease, rate of hepatitis C virus infection and immunosuppressive therapy. Fifteen (41%) hepatitis G virus-RNA seropositive patients were hepatitis C virus co-infected. Hepatitis C virus-RNA levels were significantly lower in the 15 hepatitis C virus/hepatitis G virus co-infected patients than in the 48 patients with hepatitis C virus infection only (2.2 vs 10.8 MEq/ml, p=0.02). Only 3 hepatitis G virus carriers had persistently elevated alanine aminotransferase compared to 29 hepatitis C virus carriers (14% vs 60%, p
