Long-Term Outcomes of Kidney Transplantation in Fabry Disease


Ersözlü, Sara; Desnick, Robert J; Huynh-Do, Uyen; Canaan-Kühl, Sima; Barbey, Frédéric; Genitsch, Vera; Müller, Thomas; Cheetham, Marcus; Flammer, Andreas; Schaub, Stefan; Nowak, Albina (2018). Long-Term Outcomes of Kidney Transplantation in Fabry Disease. Transplantation, 102(11):1924-1933.

Abstract

BACKGROUND: Fabry disease is a rare X-linked lysosomal storage disorder caused by mutations in the α-galactosidase A gene that obliterate or markedly reduce α-galactosidase A activity. This results in the systemic accumulation of its glycosphingolipid substrates in body fluids and organs, including the kidney. Fabry nephropathy can lead to end-stage renal disease requiring kidney transplantation. Little is known about its long-term outcomes and the overall patient survival after kidney transplantation. METHODS: Here, we report 17 Fabry patients (15 males, 2 females) who received kidney transplants and their long-term treatment and follow-up at 4 specialized Fabry centers. RESULTS: The posttransplant follow-up ranged to 25 years, with a median of 11.5 [range 0.8-25.5] years. Graft survival was similar and death-censored graft survival was superior to matched controls. Fabry patients died with functioning kidneys, mostly from cardiac causes. In 2 males 14 and 23 years posttransplant, the grafts had a few typical FD lamellar inclusions, presumably originating from invading host macrophages and vascular endothelial cells. CONCLUSIONS: We conclude that kidney transplantation has an excellent long-term outcome in Fabry disease.
