Chicken-Diet vs. Enalapril to Reduce Albuminuria

Status Completed

Clinical Trial Summary

Diabetic nephropathy (DN) is a chronic diabetic complication and affects up to 40% of patients. The first line treatment for DN is angiotensin blockers drugs that are used to reduce the protein concentration in urine.Previous data showed that this protein, namely albuminuria, could also be reduced in a short term-period by the replacement of red meat in the diet with chicken. The aim of this study is to compare the effects of this chicken diet with enalapril on albuminuria in a long-term period( 12 months)in type 2 diabetic patients.

Clinical Trial Description

Replacement of red meat in the diet with chicken reduces urinary albumin excretion rate (UAER) and improves lipid profile in type 2 diabetic patients with micro- and macroalbuminuria in short term studies. The aim of this study was to compare the long-term effect of a chicken-based diet (CD) versus enalapril treatment on renal function and lipid profile in microalbuminuric type 2 diabetic patients. In this 12-month controlled clinical trial 28 patients were randomized to an experimental diet (CD plus active placebo) or enalapril treatment (enalapril 10 mg/day plus patient’s usual diet). UAER (immunoturbidimetry), blood pressure levels, anthropometric indices, and compliance with the diet were evaluated monthly. Glomerular filtration rate (51Cr-EDTA), lipid, glycemic, and nutritional indices were measured at baseline, and quarterly. UAER was reduced after CD [n=13; 62.8 (38.4-125.1) to 49.1 (6.2-146.5) mcg/min; P<0.001] and after enalapril treatment [n=15; 55.8 (22.6-194.3) to 23.1 (4.0-104.9) mcg/min; P<0.001]. The reduction of UAER was already significant at 4th month, and there was no difference between the UAER reduction after CD [32% (95% CI: 6.7-57.6) and after enalapril treatment [44.7% (95% CI: 28.3-61.1); P=0.366]. In conclusion, CD and the ACE inhibitor enalapril promoted similar UAER reduction in patients with type 2 diabetes and microalbuminuria. A chicken-based diet might represent an additional therapeutic approach to management of diabetic nephropathy. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
