Effect of fluvastatin and dipyridamole on proteinuria and renal function in childhood IgA nephropathy with mild histological findings and moderate proteinuria.

AIM: In recent reports, some kinds of HMG-CoA reductase inhibitors were able to decrease proteinuria and to improve renal function. Here we aimed to clarify the effect of fluvastatin (an HMG-CoA reductase inhibitor) on proteinuria and renal function in children with mild IgA nephropathy. PATIENTS AND METHODS: We conducted a prospective controlled study of 30 children who had been recently diagnosed with normocholesterolemic IgA nephropathy following the detection of a minor lesion or of focal mesangial proliferation and moderate proteinuria. The 30 patients were randomly assigned to receive both of 20 mg of fluvastatin and 5 mg/kg of dipyridamole (group 1), or 5 mg/kg of dipyridamole only (group 2) for 1 year.
RESULTS: By the end of the trial, urinary protein, hematuria, BUN and serum creatinine levels had significantly decreased in the patients of group 1 as compared to baseline. Serum total cholesterol, triglyceride and LDL cholesterol levels had significantly decreased, while serum total protein and albumin, and creatinine clearance had significantly increased in group 1 as compared to baseline and group 2. The urinary protein level had significantly decreased in the group 2 patients as compared to baseline, but only slightly.
CONCLUSIONS: The results of this study suggest that fluvastatin and dipyridamole treatment yields an antiproteinuric effect and leads to the amelioration of renal function in moderately proteinuric patients with mild histological IgA nephropathy.
