title: [Incidence of TT virus infection in patients with non-A to G liver disease].
abstract: The sera of patients with liver disease associated with non-A to G hepatitis were examined for the presence of TTV DNA. These patients included 18 cases with AH, 8 cases with CH, 6 cases with LC, 4 cases with HCC, and 36 cases with blood donors. The detection of TTV DNA was performed as described by Nishizawa et al. TTV DNA was detected in 60.0%, 62.5%, 66%, 50%, 28% of the patients with AH, CH, LC and HCC, respectively. Among the patients with AH, the aminotransferases and total bilirubin values were lower in the TTV DNA-positive than -negative patients. Among the patients with chronic liver disease, however, there were no differences in the blood chemistry results between the TTV DNA-positive and -negative patients. The histological study of the liver tissues from a TTV positive patient with CH showed no evidence of necro-inflammatory reaction, although there was evidence of irregular regeneration in the TTV DNA-positive a patient. These results suggest that TTV infection may modify the pathological condition of the liver disease.
