Diabetic Nephropathy Can Be Treated with Calcium Dobesilate by Alleviating the Chronic Inflammatory State and Improving Endothelial Cell Function
Abstract
BACKGROUND/AIMS: Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease. However, no effective treatments for this disease are available. Calcium dobesilate (CaD) is widely used to treat diabetic retinopathy. DKD and retinopathy often co-exist and have similar mechanisms of pathogenesis. The aim of the present study was to elucidate the safety and efficacy of CaD in the treatment of DKD.
METHODS: In the prospective randomised controlled study, 100 DKD from Type 2 diabetes mellitus (DM) patients with a urinary albumin/ creatinine ratio (ACR) ≥30 mg/g and urinary protein level between 150 mg/24 h and 2 g/24 h with GFR> 90ml/min were enrolled. The patients were randomly divided into the treatment group (500 mg of CaD, administered orally, 3 times per day) and the control group. DKD patients were treated for 3 months. In the case control study, DM patients without proteinuria and healthy individuals were also enrolled. Clinical data and related biochemical parameters were collected. Endothelial function markers (VEGF, ET-1, eNOS, NO) and inflammatory markers (MCP-1, ICAM, PTX3) were detected by ELISA.
RESULTS: In the prospective randomised controlled study, the 24 h urinary albumin and 24 h urinary protein levels significantly decreased after three months of treatment with CaD in the patients with DKD, but the cystatin C-based glomerular filtration rate (GFR) remained unchanged. In addition, the levels of inflammatory markers (PTX3, MCP-1, hsCRP, ICAM) and…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
