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… Read more about this study

About this study

Official title: Effect of Chicken-Based Diet Versus Enalapril on Albuminuria in Patients With Type 2 Diabetes and Microalbuminuria: a One-Year Randomized Controlled Study

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.

Read the detailed 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.

Questions about this trial

What is this clinical trial studying?

A study testing enalapril and chicken diet in people with Microalbuminuria and Diabetic Nephropathy, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jun 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

urinary albumin excretion (time frame: during study). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00484068, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2007.
