Abstract

Evidence regarding long term effectiveness of enzyme replacement therapy (ERT) in Fabry disease (FD) is needed. The aim of this study was to analyze in a cohort of FD patients in Argentina, the long term effectiveness of ERT on renal, cardiac and cerebrovascular parameters.

METHODS:

Patients with genetically proven FD were included from GADYTEF (Argentinean group for the treatment of FD) between 2001 and 2014. Renal, cardiac, and cerebral outcomes were prospectively studied in patients treated with ERT. Additionally, the occurrence of major cardiac complications, stroke, end-stage renal disease and death was analyzed during follow up.

RESULTS:

During the follow-up 8 major complications occurred in 5 patients (n = 2 deaths, n = 4 cases of end stage renal disease and n = 1 atrial fibrillation), 4 of them males and only 1 female who suffered an atrial fibrillation. Sudden death or stroke did not occur. Four (40%) of 10 males with baseline left ventricular hypertrophy (LVH) reduced left ventricular mass index (LVMI) from 163.1 ± 64.7 to 123.4 ± 49.8 g/m2, 2 stabilized LVMI and 4 increased LVMI from157.9 ± 32.3 to 261.6 ± 48.6 g/m2. Estimated glomerular filtration was stable in 30 patients (17 males and 13 females).

CONCLUSIONS:

We observed a few major complications during the follow up. Future studies are necessary to show the effectiveness of ERT in affected patients.
