Delaying the Progression of Diabetic Nephropathy in Pima Indians
In Brief
An observational study for Diabetic Nephropathy. Completed, enrolled 25 participants across 1 site.
Detailed Summary
A clinical intervention will be performed in adult diabetic Pima Indians with proteinuria to determine if an angiotensin converting enzyme (ACE) inhibitor is effective in slowing the progression of renal disease in persons with overt diabetic nephropathy attributable to type 2 diabetes mellitus (NIDDM). The study will be conducted in the Gila River Indian Community and include proteinuric subjects selected from the Diabetic Renal Disease Study (DRDS; NIH Protocol Number 88-DK-79) in whom glomerular function has been measured at six-monthly intervals for the past 48 months. Twenty-five subjects (12 men, 13 women) aged 31-64 years are eligible for this study. These subjects all have urinary albumin-to-creatinine rations \>=300 mg/g (equivalent to 300 mg albumin/day), serum creatinine concentrations \< 3.0 mg/dl, and no evidence of nondiabetic renal diseases. Their GFR slopes average -0.49 ml/min/month (95% confidence interval, -0.91 to -0.07), and 11 of them (8 men, 3 women) are hypertensive (systolic blood pressure \>=140 mm Hg, diastolic blood pressure \>=90 mm Hg). Subjects will be treated with an ACE inhibitor, and measurements of glomerular filtration rate (GFR) and renal plasma flow (RPF) will be made at six monthly intervals until the subjects' progress to renal failure. GFR slope (ml.min/month) will be computed, and the slope prior to the initiation of an ACE inhibitor will be compared with that obtained during treatment.
