Risk Factors for Amyloidosis and Impact of Kidney Transplantation on the Course of Familial Mediterranean Fever

    Summary

    Background: Amyloidosis of familial Mediterranean fever (FMF) may lead to end-stage renal failure, culminating in kidney transplantation in some patients.
    Objectives: To assess demographic, clinical and genetic risk factors for the development of FMF amyloidosis in a subset of kidney-transplanted patients and to evaluate the impact of transplantation on the FMF course.
    Methods: Demographic, clinical and genetic data were abstracted from the files, interviews and examinations of 16 kidney-transplanted FMF amyloidosis patients and compared with the data of 18 FMF patients without amyloidosis.
    Results: Age at disease onset and clinical severity of the FMF amyloidosis patients prior to transplantation were similar to FMF patients without amyloidosis. Compliance with colchicine treatment, however, was much lower (50% vs. 98 %). Post-transplantation, FMF amyloidosis patients experienced fewer of the typical serosal attacks than did their counterparts (mean 2214 days since last attack vs. 143 days). Patients with FMF amyloidosis carried only M694V mutations in the FMF gene, while FMF without amyloidosis featured other mutations as well.
    Conclusions: Compliance with treatment and genetic makeup but not severity of FMF constitutes major risk factors for the development of amyloidosis in FMF. Transplantation seems to prevent FMF attacks. The protective role of immunosuppressive therapy cannot be excluded.
