Recently a newly discovered DNA virus, transfusion transmitted virus (TTV), was introduced as a cause of post-transfusion hepatitis. We studied the frequency of TTV viremia in 60 hemodialysis patients in Yamaguchi, Japan. TTV DNA was detected by heminested PCR, using primers described by Okamoto et al. TTV DNA was detected in 18 patients (30%). There was no differences in clinical characteristics, including age, gender, history of blood transfusion, and double infection of other hepatitis viruses, between TTV DNA positive patients and negative patients. Also the frequency of TT viremia was not associated with the duration of hemodialysis. These results suggest that the routes of TTV infection may be different from those of infection by HBV, HCV, or HGV. |
