Effects of Curcumin Supplementation on Gut Barrier Function in Patients With Metabolic Syndrome

Not Applicable

Completed

• Conditions: Obesity; High Cholesterol; Heart Diseases; High Blood Pressure; Type2 Diabetes
• Interventions: Dietary Supplement: Curcumin

• Registration Number: NCT03542240
• Lead Sponsor: Virginia Commonwealth University

Brief Summary

This study will investigate the effects of curcumin on the structure/function of the body by investigating whether targeted improvement of intestinal barrier function by supplementation with oral curcumin will result in attenuation of lipopolysaccharide (LPS) translocation and/or intestinal inflammation.

Detailed Description

A typical diet in the United States, also known as Western diet, is very high in sugars and saturated fat, and poor in food such as fruits, vegetables, fish and whole grains. This type of diet is associated with higher risk to develop obesity and other health problems such as high blood pressure, high cholesterol, Type 2 diabetes, and heart disease. Western diet can also cause changes in the gut that allow bacteria that are typically only present in the gut to leak out into the bloodstream. It is thought that having gut bacteria in the bloodstream may play a role in the development of diseases like Type 2 diabetes and heart disease.

Curcumin is a dietary supplement that comes from the root of the turmeric plant, and it may have an effect on the function of the gut and the leakage of gut bacteria into the bloodstream. The purpose of this research study is to evaluate the effects of daily curcumin dietary supplements on the function of the gut in subjects who are at risk for cardiovascular and metabolic diseases, for example they have increased blood pressure, increase waist circumference and high triglycerides (fat in the blood).

Primary Outcome Measures

Name	Time	Method
Change inintestinal permeability	Baseline to 12 months	Measured by level plasma lipopolysaccharide (LPS). A reduction in LPS suggests a reduction in intestinal permeability
Change in intestinal barrier function	Baseline to 12 months	Measured by level of excreted Zonulin in stool samples. A reduction in Zonulin suggests a reduction in intestinal barrier function
