  • Title: Effect of captopril on renal hemodynamics and renal prostaglandins in early type II diabetic patients with normo-or microalbuminuria.

    Abstract:
    In this study, we investigated the effect of captopril (CPT) on glomerular filtration rate (GFR), effective renal plasma flow (ERPF), filtration fraction (FF), urinary albumin excretion (UAE) and daily urinary excretion of thromboxane B2 (TXB2) and 6-keto- prostaglandin F1a (6-keto-PGF1a) in 29 normotensive non-insulin-dependent diabetes (NIDDM) patients without clinically discernible nephropathy. Before treatment, urinary excretion 6-keto-PGF1a was significantly increased (P < 0.05) in 29 NIDDM patients compared with 25 health subjects matched for age and sex. The values of GFR and FF were significantly higher (P < 0.01 and P < 0.005, respectively) in NIDDM than in normal volunters, whereas ERPF was comparable in both groups. Meanwhile we observed that UAE of early NIDDM was increased before treatment. After CPT treatment, GFR, FF, UAE and urinary excretion of 6-keto-PGF1a were significantly reduce (all P < 0.005) compared with those of NIDDM before treatment. These data indicated that CPT is effective in lowering glomerular filtration pressure and ameliorating microalbuminuria in the normotensive early NIDDM.
