title: [Involvement of TTV, a new infectious factor in post-transfusion hepatitis, non A-non G].
abstract: Post-transfusion hepatitis developed in 6 of 447(1.3%) patients who received transfusion even after 1992 when HCV screening by PHA method was started. The six patients were suggested as hepatitis, non-B, non-C, non-G type. Of the six patients, 4 were found to be infected with TTV, which was identified in one of the patients. The patients became positive for TTV DNA before or almost the same time as the development of hepatitis and their amounts of TTV DNA were varied depending on the ALT level, suggesting that their hepatitis might be caused by TTV. The patients who presented hepatitis became positive for TTV DNA in the 6-10th week after transfusion, whereas more than half of the patients with a slight hepatic disorder became positive in the 2-4th week after transfusion. In addition, prolonged infection with TTV was only observed in nearly half of 23 patients.
