1 Metabolic and Cardiovascular Impact of CD36 Deficiency in African Americans

CD36, a protein that facilitates tissue uptake of fat, as a common link between blood fat concentrations and metabolic disease states such as diabetes mellitus. Genetic variants in the CD36 gene are more common in African Americans compared to Whites and it may confer protection against metabolic diseases by altering the amount of fat in the blood. The purpose of this study is to compare the levels of fat in the blood and to assess endothelial dysfunction among carriers versus non-carriers of the coding SNP, rs3211938 of the CD36 gene after a high fat meal challenge

NCT02126735 Obesity

The purpose of this study is to compare the levels of fat in the blood and to assess endothelial dysfunction among carriers versus non-carriers of the coding SNP, rs3211938 of the CD36 gene after a high fat meal challenge Area Under the Concentration-Time Curve triglycerides levels after high fat meal.

We expect that subjects heterozygous for the minor allele of CD36 rs3211938 (G/T) would have an increase of 250 units in the area under the curve for triglycerides which is ~50% of the observed difference between patients with CD36 deficiency and normal controls.

Primary Outcomes

Description: We expect that subjects heterozygous for the minor allele of CD36 rs3211938 (G/T) would have an increase of 250 units in the area under the curve for triglycerides which is ~50% of the observed difference between patients with CD36 deficiency and normal controls. Assuming that the common standard deviation is 199, using a two group t-test with a type I error of 0.05, a total of 28 subjects (14 carriers and 14 non-carriers) would provide 90% power to detect a difference in our primary endpoint between carriers versus non-carriers of genotype

Measure: Area Under the Concentration-Time Curve triglycerides levels after high fat meal

Time: Baseline values prior to high fat meal and at 10, 20, 30, 60, 120, 240 & 360 minutes

Secondary Outcomes

Description: our primary outcome will be the percent change in flow mediated dilation at baseline and 4 hours after a high fat meal (peak effect). Assuming a conservative estimate of standard deviation of 3.19 our proposed study with a total of 28 subjects (14 carriers and 14 non-carriers) would have at least 80% power with type I error of 0.05 to detect a minimum difference in the mean response of 3.5 %.

Measure: percent change in flow mediated dilation at baseline and 4 hours after a high fat meal

Time: Change from baseline in flow mediated dilation at 4 hours after high fal meal

2 Role of CD36 in Nutrient Delivery and Its Dysfunction in African Americans

This proposal will test the hypothesis that chronic treatment with sildenafil with and without the use of nitric oxide substrate, L-arginine, protects against fatty acid induced impairment of endothelial function, improves insulin-stimulated microvascular recruitment, insulin sensitivity and glucose uptake in CD36 rs3211938 G-allele carriers.

NCT03012386 Insulin Resistance Endothelial Dysfunction Drug: Sildenafil Citrate
MeSH: Insulin Resistance
HPO: Insulin resistance

CD36 in Nutrient Delivery and Its Dysfunction This proposal will test the hypothesis that chronic treatment with sildenafil with and without the use of nitric oxide substrate, L-arginine, protects against fatty acid induced impairment of endothelial function, improves insulin-stimulated microvascular recruitment, insulin sensitivity and glucose uptake in CD36 rs3211938 G-allele carriers.

- Hematocrit < 34% - Any underlying or acute disease requiring regular medication which could possibly pose a threat to the subject or make implementation of the protocol or interpretation of the study results difficult - Treatment with chronic systemic glucocorticoid therapy (more than 7 consecutive days in 1 month) - History of alcohol or drug abuse - Treatment with any investigational drug in the one month preceding the study - Mental conditions rendering a subject unable to understand the nature, scope and possible consequences of the study - Inability to comply with the protocol, e.g., uncooperative attitude, inability to return for follow-up visits, unlikelihood of completing the study, and investigator discretion Insulin Resistance Endothelial Dysfunction Insulin Resistance Subjects carrying the G-allele of CD36 coding SNP rs3211938 that results in 50% reduction of CD36 levels in ~25% of African Americans have endothelial dysfunction.

Primary Outcomes

Description: The primary endpoint is the change in microvascular blood volume (ΔMBV) during insulin infusion from baseline, an index of insulin-stimulated microvascular recruitment.

Measure: insulin-stimulated microvascular recruitment.

Time: 4 weeks

Secondary Outcomes

Description: Glucose infusion rate during hyperinsulinemic euglycemic clamp

Measure: Insulin sensitivity

Time: 4 weeks
