LACK OF EVIDENCE FOR HEPATITIS-B VIRUS (HBV) INFECTION IN FULMINANT NON-A, NON-B-HEPATITIS

We studied eight patients who had orthotopic liver transplantation for fulminant hepatic failure in the course of acute non-A, non-B hepatitis. HBV DNA was searched for extensively in the liver tissue by PCR using several sets of primers in conventional and heminested reactions. All patients were negative for HBV DNA in liver tissue by all assays employed; furthermore, they were negative for HEV RNA, HCV RNA, and HBV DNA in serum. Although the causative role of HEV and HCV in fulminant non-A, non-B hepatitis cannot be excluded, our data do not support a causative association between this syndrome and HBV infection.
