Effect of Dipyridamole Treatment on Proteinuria in Pediatric Renal Disease

Abstract

The effect of dipyridamole on proteinuria was studied in 60 children with various renal diseases. A significant decrease in 24-hour urine protein excretion was observed within a few months after treatment in 32 (53%) of the patients with minimal or moderate mesangial proliferation. The effect was reproducible and parallelled by a reduction in plasma levels of beta-thromboglobulin. Renal function in patients significantly improved with the therapeutical effect. The appropriate dosage was 4-10 mg/kg daily and no serious toxicity was seen despite large dosage and even in long-term application. The data suggest that dipyridamole treatment appears safe and has a beneficial effect on proteinuria dependent on its effect on platelets in renal disease.
