Özet

Background: The aim of this study was to find out whether the beneficial effects of the renin-angiotensin-aldosterone system (RAS) blockage in chronic kidney disease (CKD) has any relation with the alteration of asymmetric dimethylarginine (ADMA) levels. Methods: Sixty-six nondiabetic patients with CKD and proteinuria and 36 healthy subjects were enrolled. Patients were treated with either ramipril 5 mg daily or valsartan 160 mg daily for 3 months. Proteinuria, ADMA, symmetric dimethyl arginine (SDMA), flow-mediated dilatation (FMD) and HOMA index measurements were performed both before and after the treatment. Results: ADMA, SDMA, hsCRP levels, HOMA index and proteinuria of patients were significantly higher (p < 0.001 for all) and FMD, L-arginine and L-arginine/ADMA ratio in CKD were significantly lower than controls. According to the multiple regression analysis, proteinuria levels were independently related to ADMA and SDMA levels. Conclusion: Both drugs were equally effective in reducing elevated ADMA levels and improving endothelial dysfunction in CKD patients. Copyright © 2007 S. Karger AG.
