Graft-versus-host disease (GVHD) is a common complication following an allogeneic tissue transplant. It is commonly associated with stem cell or bone marrow transplant but the term also applies to other forms of tissue graft. Immune cells (white blood cells) in the tissue (the graft) recognize the recipient (the host) as foreign. The transplanted immune cells then attack the host’s body cells. GVHD can also occur after a blood transfusion if the blood products used have not been irradiated.
