ESRD is a major cause of morbidity and premature mortality in Fabry disease, particularly in classically affected males. The decline of renal function in Fabry nephropathy is adversely affected by male gender, advanced chronic kidney disease (CKD), and severe proteinuria. The diagnosis of Fabry nephropathy may be missed if not specifically addressed in progressive CKD and patients have been first identified in screening programs of dialysis patients. Fabry patients have worse 3-year survival rates on dialysis as compared with nondiabetic controls. The 5-year survival rate of transplanted Fabry patients is also lower than that of controls. However, because Fabry nephropathy does not recur in the allograft and transplanted Fabry patients appear to have better overall outcomes than those maintained on dialysis, kidney transplantation should be recommended as a first choice in renal replacement therapy (RRT) for Fabry disease. Appropriately designed and powered studies are not available to answer the question whether enzyme replacement therapy (ERT) influences outcomes, the course of cardiomyopathy, events, or survival in Fabry patients on RRT. The authors are not aware of compelling indications for ERT in RRT patients because progression of cardiomyopathy was documented during ERT. Whether the excess mortality risk of Fabry patients on RRT can be prevented by ERT is unknown. Despite observational reports of symptomatic improvement, the available evidence supporting ERT for such patients is not compelling enough. To clarify this issue, studies are needed to test the effectiveness of agalsidases in preventing cardiac and cerebrovascular complications in Fabry patients with ESRD.

Background and objectives: This open, prospective, randomized trial aimed to assess the effects of statins in chronic kidney disease patients on optimized antiproteinuric treatment with combined angiotensin-converting enzyme inhibition and angiotensin receptor blockade.

Design, setting, participants, & measurements: After 1-month benazepril therapy followed by 1-month benazepril-valsartan combined therapy (run-in), 186 consenting patients with residual proteinuria >0.5 g/24 h were randomized to 6-month benazepril-valsartan therapy alone or combined with fluvastatin. Between-groups changes in proteinuria (primary outcome), serum lipids, and GFR were compared by ANCOVA. Analyses were blinded and by intention to treat.

Results: During the run-in, proteinuria decreased more on benazepril-valsartan than on benazepril alone. Proteinuria reduction correlated with concomitant reduction in total, LDL, and HDL cholesterol, and apolipoprotein B and apolipoprotein A levels. After randomization, median proteinuria similarly decreased from 1.2 (0.6 to 2.2) to 1.1 (0.5 to 1.7) g/24 h on fluvastatin and from 1.5 (0.8 to 2.7) to 1.0 (0.5 to 2.4) g/24 h on benazapril-valsartan therapy alone. Fluvastatin further reduced total and LDL cholesterol and apolipoprotein B versus benazepril-valsartan alone, but did not affect serum triglycerides and GFR. Treatment was well tolerated.

Conclusions: In chronic kidney disease patients with residual proteinuria despite combined angiotensin-converting enzyme inhibitor and angiotensin receptor blockade therapy, add-on fluvastatin does not affect urinary proteins, but further reduces serum lipids and is safe. Whether combined angiotensin-converting enzyme inhibitor, angiotensin receptor blockade, and statin therapy may improve cardiovascular outcomes in this high-risk population is worth investigating.
