NCT ID: NCT01107808 Withdrawn - Obesity Clinical Trials

Calcium, Vitamin D and Metformin to Treat Insulin Resistance in Obese African American Adolescent Females

Start date: June 2009
Phase: N/A
Study type: Interventional

This is a feasibility study to examine the treatment with Metformin, vitamin D with calcium supplement for insulin resistance in obese, black, female teens. The association of low vitamin D levels and decreased insulin sensitivity has been established. Thus, the specific aims of this study are: Specific aim 1: To examine the effect of an 8-week treatment with vitamin D and calcium supplementations on diabetes-related risk factors in obese, black, female teens. Hypothesis 1a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to controls not receiving vitamin D and calcium. Hypothesis 1b: In obese, black teen females with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of cardiovascular disease (decreased BMI and improved triglycerides and LDL) when compared to controls not receiving vitamin D and calcium. Specific aim 2: To determine if the addition of Metformin to the 8-week treatment with vitamin D and calcium supplementations improves diabetes-related risk factors in obese, black, female teens. Hypothesis 2a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium. Hypothesis 2b: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of cardiovascular disease risk (as determined by the decreased BMI, improved triglycerides and LDL) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium.

NCT ID: NCT01106313 Completed - Depression Clinical Trials

Insulin Resistance in Patients With Major Depression

Start date: July 2009
Phase: N/A
Study type: Observational

The purpose of this study is to study the relationship between insulin and glucose action and neuropsychological functioning (memory, attention, general thinking abilities) in persons with depression.

NCT ID: NCT01105143 Completed - Obesity Clinical Trials

Effects of Negative Energy Balance on Muscle Mass Regulation

Start date: March 2012
Phase: N/A
Study type: Interventional

The investigators here propose to perform a prospective randomized intervention trial in post-menopausal women to investigate the endocrine network, which contributes to the changes in skeletal muscle mass during weight loss.

NCT ID: NCT01103921 Completed - Metabolic Syndrome Clinical Trials

The Metabolic Effects of Consuming Sugar-Sweetened Beverages for Two Weeks

DRS
Start date: October 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to examine the effects of consumption of sugar-sweetened beverages on blood triglycerides and cholesterol, cholesterol concentrations, and the body's sensitivity to insulin.

NCT ID: NCT01093651 Completed - Diabetes Clinical Trials

Dipeptidyl Peptidase-4 Inhibition and Immune Function in HIV

DPPIVinHIV
Start date: June 2010
Phase: Phase 2/Phase 3
Study type: Interventional

We will test the safety of a new class of anti-diabetes compounds (DPPIV-inhibitors) in people living with HIV. Future trials will examine efficacy for treating diabetes and reducing cardiovascular disease risk in people living with HIV.

NCT ID: NCT01093417 Completed - HIV Infections Clinical Trials

Study of Vitamin D and Effect on Heart Disease and Insulin Resistance

Start date: January 2010
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate how Vitamin D affects endothelial function, inflammation, lipids, insulin resistance, vitamin D levels, and PTH.

NCT ID: NCT01087632 Completed - Metabolic Syndrome Clinical Trials

Armolipid Plus and Metabolic Syndrome

Start date: September 2009
Phase: N/A
Study type: Interventional

Metabolic syndrome is a highly prevalent condition characterized by visceral obesity, abnormalities of glucidic and lipid metabolism, and increased risk for cardiovascular events. Such findings appear to be associated with a decrease in insulin sensitivity. Management of metabolic syndrome is currently aimed at treating individual components of the disease without addressing this underlying pathophysiologic mechanism; this translates into multidrug regimens, high costs and patient compliance issues. Armolipid Plus (an association of berberine 500 mg, red yeast rice titled in 3 mg monacolin K,policosanol 10 mg,coenzyme Q10 2 mg,astaxanthin 0,5 mg,folic acid 0,2 mg) has been found to be effective at reducing blood cholesterol and triglycerides, and at improving endothelial function; subgroup analyses also suggested a benefit on indices of insulin resistance. Aim of the study is to evaluate the effects of Armolipid Plus on insulin sensitivity and on the diagnostic parameters of metabolic syndrome. 60 patients will be enrolled in this randomized, double-blind, placebo-controlled trial; active treatment will consist of Armolipid Plus (1 tbl qd). Primary end point will be the reduction of the insulin/glucose ratio, both after overnight fast (HOMA index) and after an oral glucose tolerance test (OGTT).

NCT ID: NCT01080339 Terminated - Insulin Resistance Clinical Trials

Substudy of Change in Cardiometabolic Disease (CMD) Risk Factors During an Interactive Fitness Program

EXCEL
Start date: February 2010
Phase: N/A
Study type: Observational

Substudy examining cardiovascular and metabolic risk factor change in children at high risk for future atherosclerosis who are enrolled in a pilot intervention using novel gaming and exercise activities to increase physical activity.

NCT ID: NCT01077479 Completed - Metabolic Syndrome Clinical Trials

Metformin in Preventing Androgen Deprivation Therapy Induced Insulin Resistance and Metabolic Syndrome

MVENT
Start date: February 2010
Phase: Phase 2
Study type: Interventional

The main purpose of this study is to assess the efficacy of metformin in abrogating androgen deprivation therapy (ADT) induced insulin resistance as measured by homeostasis model assessment (HOMAIR) in men with non-metastatic prostate cancer.

NCT ID: NCT01075022 Enrolling by invitation - Insulin Resistance Clinical Trials

Effect of a Single Colecalciferol Dose on Insulin Resistance

Start date: May 2009
Phase: N/A
Study type: Interventional

A Prospective Double-Blinded, Placebo Controlled, Randomized Trial comparing a single dose of Vitamin D (Colecalciferol) 300.00UI to placebo on patients with insulin resistance. Primary Outcome: Blood glucose and homeostasis model assessment for insulin resistance (HOMA-R) after 90 days. Study hypothesis: Vitamin D treatment may improve insulin resistance and decrease glucose level, since there is an association between hypovitaminosis D and increased insulin resistance.
