Abstract
We report a case of graft intolerance syndrome in which transplant nephrectomy was performed 11 years after kidney transplantation. A 46-year-old man was admitted to our hospital in February 2018 with a mild fever, left lower abdominal pain, and gross hematuria with enlargement of the transplanted kidney. Urinary tract infection was ruled out. Because the symptoms developed after the immunosuppressants had been stopped after kidney graft loss, graft intolerance syndrome was suspected. He had lost his graft in 2016 and had stopped all immunosuppressants since January of 2017. Immunosuppressive therapy was intensified, and steroid half-pulse therapy was added for 3 days. After the steroid pulse therapy, the C-reactive protein (CRP) decreased from 6.47 mg/dL to 0.76 mg/dL, but there was little improvement in the symptoms, and the CRP then increased to 4.44 mg/dL. Transplant nephrectomy was performed in March 2018. Postoperatively, the symptoms disappeared without the administration of immunosuppressants, and the CRP decreased. Pathologically, the resected kidney graft showed persistent active allograft rejection with severe endarteritis, transplant glomerulopathy, and diffuse interstitial fibrosis. Massive thrombi occluded the large arteries, and there was extensive hemorrhagic cortical necrosis. Transplant nephrectomy is uncommon in patients >6 months after transplantation. However, even if more time has passed since transplantation, as in this case, transplant nephrectomy may be a valid option in some cases of severe graft intolerance syndrome.Keywords
