Fulminant adenovirus hepatitis after allogeneic bone marrow transplantation

Adenoviruses may cause severe infections in bone marrow transplant recipients. We report the case of a patient who developed fulminant hepatitis 5 months after bone marrow transplantation. Adenovirus type 2 was cultured from stool and blood samples. The patient died from liver failure. Histologic examination of post-mortem liver samples showed extensive necrosis with nuclear inclusions. Adenovirus was identified in liver cells by electron microscopy and immunohistochemical staining using a monoclonal anti-adenovirus antibody. No other pathogen was identified.
