Acute graft-versus-host disease in pancreas transplantation: a comparison of two case presentations and a review of the literature.

As a complication of solid organ transplantation, acute graft-versus-host disease (GVHD) is most associated with small bowel and liver transplants. We present two cases of acute GVHD following pancreas transplantation. Case 1 was a 27-year-old female who underwent cadaveric pancreas transplant 9 months after a successful live donor kidney transplant. Case 2 was a 38-year-old male who received a simultaneous cadaveric pancreas and live donor kidney transplant. Both patients presented within 30 days of transplant with nonspecific symptoms. Rejection and infection were ruled out. Both subjects had progressive decline in mentation associated with pancytopenia and hyperbilirubinemia. Rash was not present until late in their hospital course. Skin biopsies demonstrated mixed chimerism with pancreas donor DNA diagnostic of GVHD. Acute GVHD is a rare, often fatal, complication of pancreas transplantation, and its presentation appears to differ from acute GVHD associated with stem cell transplantation.
