AbstractThis study focuses on the prevalence of hepatitis G virus (GBV-C/HGV) in hemodialysis patients and blood donors in Denizli (located at Aegean region of Turkey). A total of 100 patients (mean age: 56.8 +/- 13.3 years; 46 female) receiving hemodialysis and 100 blood donors (mean age: 31.3 +/- 8.1 years; 8 female) were included in the study. The presence of GBV-C/HGV RNA was determined in all patients by reverse transcriptase-PCR and the presence of GBV-C/HGV anti-E2 antibodies was determined by a commercial enzyme immunoassay (Diagnostic Automation, INC). Viral RNA positivity was determined in 14 (14%) of the hemodialysis patients and 2 (2%) of the blood donors, the difference being statistically significant (p < 0.05). GBV-C/HGV anti-E2 antibodies were detected in 1 (1%) of the hemodialysis patients and 3 (3%) of the blood donors. Anti-E2 positive patient also revealed positive result for viral RNA. There was no statistically significant difference between the two groups in terms of anti-E2 positivity. The prevalence of GBV-C/HGV was 14% in hemodialysis patients and 5% in blood donors (p < 0.05). There was no significant difference in terms of duration of hemodialysis, serum ALT levels, age or gender between GBV-C/HGV positive and negative hemodialysis patients. In conclusion, since hemodialysis patients are at an increased risk of parenteral transmission, they have significantly higher GBV-C/HGV viremia rates and prevalence when compared to blood donors. However, the prevalence of GBV-C/HGV and coexistence between GBV-C/HGV and hepatitis C virus have been decreasing in our region owing to increased hygienic precautions in hemodialysis units, avoidance of unnecessary blood transfusions and more widespread use of erythropoietin.
