Effect of Angiotensin Converting Enzyme Inhibitor, Lisinopril, on Renal Blood Flow and Its Correlation With Proteinuria Reduction in Subjects With Type 2 Diabetes and Kidney Disease

2014-08-27 03:14:39 | BioPortfolio

Summary

The purpose of the study is to investigate the effect of a blood pressure medication, Lisinopril, or similiar drugs in that class, on the flow of blood to the kidneys. In this study, we will compare blood flow to the kidneys in healthy people that do not have diabetes or kidney disease with people that have diabetes and evidence of kidney disease.

Description

Blockers of renin angiotensin aldosterone system (RAAS) are considered the standard of care in treatment of diabetic nephropathy. Their effects are thought to be through multiple mechanisms, including reducing intraglomerular pressure. However, due to the lack of a sensitive, practical and noninvasive method of monitoring renal hemodynamics, the magnitude of hemodynamic effects of these agents and its contribution to proteinuria reduction has not been studied in humans. At the same time, it is not clear if treatment with blockers of the RAAS have similar renal hemodynamic effects in individuals with and without diabetes and kidney disease.

Up to 36 subjects with type 2 diabetes and more than 500 mg of proteinuria who are on stable doses of ACE inhibitors or angiotensin receptor blockers (ARBs) and up to 18 healthy volunteers will be enrolled in this study. Subjects with type 2 diabetes will be asked to stop their ACE inhibitor or ARB medications for 10 days. Between 7 to 10 days after stopping these medications renal blood flow (RBF) will be measured using contrast enhanced ultrasound (CEU) and urine protein will be measured as well for comparison to baseline. Subjects' ACE inhibitors or ARB will be restarted and RBF measurement using CEU and measurement of urine protein excretion will be repeated after 7 days. For comparison, RBF will be measured by CEU in up to 18 healthy volunteers. They will then be started on Lisinopril 10 mg orally once a day for 7 days. On day 7 RBF measurement will be repeated to assess the effect of ACE inhibitors on RBF in healthy individuals as compared to those with diabetic nephropathy.

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
