[Adenovirus-induced liver failure in adults following allogeneic hematopoietic stem cell transplantation: a report of two cases and literature review].

Human adenovirus (HAdV) hepatitis is a rare but rapidly progressive and often fatal complication following allogeneic hematopoietic stem cell transplantation. The present study reported the management of two patients with lymphoproliferative disease who developed HAdV infection after haploidentical hematopoietic stem cell transplantation and subsequently died of liver failure. These cases highlight the importance of early multi-site screening, dynamic monitoring, and timely intervention for HAdV in high-risk patients to reduce mortality risk and improve prognosis.
