Chronic graft versus host disease

Chronic graft versus host disease (GVHD) is a complication that can occur after a stem cell or bone marrow transplant in which the newly transplanted donor cells attack the transplant recipient's body. Symptoms may include skin rash, mouth sores, dry eyes, liver inflammation, development of scar tissue in the skin and joints, and damage to the lungs. The exact cause of chronic GVHD is unknown. It likely results from a complex immune-mediated interaction between the donor and recipient cells. Chronic GVHD is treated with prednisone or other similar anti-inflammatory or immunosuppressive medications.
