Abstract
A 19-year-old male healthy hepatitis B virus (HBV) carrier developed fulminant hepatitis following allogenic bone marrow transplantation (BMT) from his brother, who was also a healthy HBV carrier, during the first complete remission of acute myelogenic leukemia (M1, FAB classification). Serum markers related to both HBV and hepatitis C virus (HCV) were elevated during active liver injury when a point mutation in the precore (pre-C) region occurred in the HBV. The patient received low-dose interferon alpha (IFN-α), while the dose of cyclosporin A was tapered; the patient eventually recovered from the liver injury. Fulminant hepatitis due to HBV and/or HCV following BMT is rare, and it is considered to have a very poor prognosis. The rationale for the use of low-dose IFN-α with cyclosporin A (CyA) is discussed.
