[The prevalence of TTV infection and the route of TTV transmission in hemodialysis patients--compared with HCV infection].
Recently a novel virus named TT virus (TTV), associated with posttransfusion hepatitis, was isolated. The prevalence of TTV infection and the route of TTV transmission in HD units was investigated. TTV was detected in 51.3% of patients on HD (59/115), as compared with 16.5% of healthy blood donors (15/91). The prevalence rate of TTV in the patients without history of blood transfusion was similarly high (51.6%), compared with that of those with history of blood transfusion (51.2%). The prevalence rate of TTV did not differ according to the duration of HD. These suggest that the risk of TTV infection is very high in HD units and there is another major route of TTV transmission than blood transfusion.
