Transfusion associated graft versus host disease.

ABSTRACT

Transfusion-associated graft-versus-host disease (TA-GVHD) is a dreaded complication in immunocompromized hosts. The diagnosis is often delayed because of lack of awareness and the non-specific clinical features. More than 90% patients succumb to refractory infections. The only effective preventive measure is administration of irradiated blood products, which must be made available in centers managing immunocompromised patients. We report three cases and discuss pathophysiology and preventive strategies in this communication.
