Transfusion-transmitted virus (TTV) is a single-stranded DNA virus that was identified in patients with post-transfusion hepatitis of non-A-to-G type. Patients with chronic renal failure on maintenance hemodialysis (HD) have a higher risk of viral infections, and the prevalence of TTV infection is common. The aim of our study was to detect TTV-DNA and its genotype in HD patients. A case-control study compromising of 63 patients on maintenance HD therapy at the Nephrology Center of Central Arar Hospital and 100 healthy individuals who were tested for TTVDNA and its genotype by semi nested-polymerase chain reaction with primers derived from the conserved open reading frame 1 (ORF1) region followed by digestion with NdeI and PstI restriction enzyme. The results show that the prevalence of TTV in HD patients was high and statistically significant; 42.9% compared with 19% in the control group. History of blood transfusion was the only significant predictor, and we found that age of patients, duration of HD, hepatitis B and C infection, aspartate aminotransferase and alanine aminotransferase levels were not significant predictors of TT virus positivity in HD patients. TTV genotype 1 (G1) was found to be the most common genotype among both HD and healthy controls. The prevalence of TTV among HD patients was significantly higher than that in healthy individuals. History of blood transfusion was the only significant predictor of TTV positivity among them. Genotype 1 was the most predominant type among HD and healthy individuals. Further studies on TTV in peritoneal dialysis patients and transplant patients are needed.
