Previous reports documented the recovery of a DNA virus from a patient with posttransfusion non-A-G hepatitis and named TT virus (TTV). Although the virus was initially detected as a causative agent of hepatitis, there is doubt about its pathogenicity. The aim of this study was to clarify the relationship between TTV and liver diseases. Histopathological examination of liver biopsies from 14 patients with TTV genotype 1 positive non-B, non-C and non-G chronic hepatitis showed mild fibrosis and periportal/piecemeal necrosis. Using the real-time detection (RTD)-PCR method, we found that TTV DNA levels of genotype 1 in liver samples from 3 such patients were 100- to 1,000-fold higher than those in the paired serum samples. Further investigation using various tissues from 2 autopsies of patients with hepatitis C with hepatocellular carcinoma revealed that the concentrations of TTV DNA in the liver were also higher than in serum samples. However, the highest TTV DNA concentrations in these 2 autopsies were found in the lung and bone marrow, respectively. Our results suggest that TTV may replicate in various tissues including the liver and may cause only mild liver damage.
