Graft-Versus-Host Disease After Pancreatic Transplantation

Transplantation for type 1 diabetes: radiologist's primer on islet, pancreas and pancreas-kidney transplantation imaging

Whole-organ pancreas, pancreatic-kidney and islet transplantation are surgical therapeutic options for the treatment of type 1 diabetes. They can enable effective glycemic control, improve quality of life and delay/reduce the secondary complications of type 1 diabetes mellitus. Radiologists are integral members of the multidisciplinary transplantation team involved in these procedures, with multimodality imaging serving as the mainstay for early recognition and management of transplant related complications. This review highlights the transplantation procedures available for patients with type 1 Diabetes Mellitus with a focus on the imaging appearance of transplantation-related complications.

Acute Graft Versus Host Disease After Kidney-Pancreas Transplant

Acute graft vs. host disease (aGVHD) results from newly transplanted donor immune cells recognizing recipient tissues as foreign, leading to end-organ damage. Diagnosing aGVHD typically involves a combination of clinical evaluation, histological examination, laboratory tests, and imaging studies. Although typically associated with allogeneic stem cells transplant and less frequently with liver or small bowel transplants, solid organ transplant GVHD (SOT-GVHD) associated with kidney-pancreas transplants is exceedingly rare. Our patient presented with pancytopenia unexplained by typical causes. He developed classical aGVHD findings of fever, diarrhea, rash, and abnormal liver tests. Our case underscores the importance of keeping a broad differential when evaluating solid organ transplant patients.
