Long-term Results of Kidney Transplantation in Patients With Familial Mediterranean Fever and Amyloidosis.

Introduction: Amyloid A amyloidosis is most commonly caused by familial Mediterranean fever (FMF) in Turkey. Amyloidosis secondary to FMF is an important cause of end-stage renal failure, and kidney transplantation (KT) in these cases can be complicated, with long-term results oftentimes inferior compared with organ transplant in patients without FMF. The present study aims to show the long-term results of patients with secondary amyloidosis caused by FMF undergoing KT .
Methods: We enrolled 27 patients with a history of FMF amyloidosis undergoing KT and a control group of 614 patients undergoing KT between 2005 and 2018 at Ankara University Medical School. All data were recorded retrospectively from patients files.
Results: Twenty-two patients (81.5%) were treated with triple immunosuppressive therapy consisting of mycophenolate mofetil, tacrolimus, and a steroid; 5 patients (18.5%) were treated with tacrolimus, azathioprine, and prednisolone. Acute cellular rejection was seen in 3 patients (11.1%), and acute cellular- and antibody-mediated rejection occurred in 1 patient (3.7%). During the follow-up period, graft loss due to acute cellular rejection was observed in only 1 patient. One patient was lost to follow-up.
