Insulin Resistance clinical trials at UC Health
6 in progress, 4 open to eligible people

  • A Study of the Effect of Orange Juice or Sugar-Sweetened Beverages on Risk Factors for Type 2 Diabetes and Cardiovascular Disease

    “In this study, the study team will provide meals and either sugar-sweetened beverages or orange juice.”

    open to eligible people ages 18-50

    The objectives of this proposal are to address the gaps in knowledge regarding the metabolic effects of consuming orange juice, the most frequently consumed fruit juice in this country, compared to sugar-sweetened beverage.

  • Metformin, Vitamin D, and Depression in Polycystic Ovary Syndrome (PCOS) Trial

    open to eligible females ages 18-45

    Open-label randomized clinical trial assessing the efficacy of Metformin versus Vitamin D in improving symptoms of depressed mood in polycystic ovary syndrome.

  • Study of Time-restricted Eating on Weight Loss.

    open to eligible people ages 18-64

    This is a randomized controlled trial studying the effects of time-restricted feeding (TRF) on weight loss in obese humans. Obesity is the number one risk factor for type 2 Diabetes Mellitus (T2DM), and numerous studies demonstrate that weight loss is an effective strategy to prevent T2DM and improve the metabolic health of people diagnosed with T2DM. Unfortunately, classical calorie restriction diets often fail to produce long-term weight loss due to low compliance, reduced resting metabolic rate (RMR), and other factors. Therefore, novel dieting techniques must be explored in order to successfully treat obesity and prevent T2DM. Studies in mice provide compelling evidence that feeding/fasting cycles can be altered to produce beneficial effects on weight loss and metabolic health markers in the absence of calorie restriction. Limited research in human subjects suggests that this feeding paradigm may translate to human health as well, however, more research needs to be done in order to confirm this hypothesis. This study will determine if TRE can lead to weight loss in obese human subjects. Secondary outcomes include changes in body composition, HOMA-IR, hormonal and biochemical serum markers, RMR, and total energy expenditure (TEE).

  • Tissue-specific Insulin Resistance in Obstructive Sleep Apnea: Role of Hypoxia

    open to eligible people ages 40-70

    Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.

  • Insulin Resistance in HCV Infection

    Sorry, in progress, not accepting new patients

    The study hypothesis is that the means by which HCV induces glucose intolerance is through impairment of B-cell function and compensatory hyperinsulinemia in predisposed Latinos with insulin resistance and that HCV eradication improves these abnormalities. It is also hypothesized that moderate alcohol consumption impact insulin sensitivity and secretion with Latinos with or without HCV infection.

  • Study of the Relationship Between Body Composition, Insulin Resistance and HDL Levels

    “HDL Study”

    Sorry, accepting new patients by invitation only

    Approximately 20 million people in the United States have some form of kidney failure. People with kidney failure have an increased chance of having low levels of high density lipid (HDL), so called "good cholesterol." Patients who are overweight or obese also have low levels of HDL. The investigators are trying to find out whether causes of low HDL are the same in people who are overweight and in patients with kidney failure so that in the future doctors can better treat low HDL cholesterol levels. People with low levels of HDL are more likely to have heart attacks and strokes and are more likely to lose kidney function. This study hope to learn more about how kidney failure causes low HDL cholesterol levels.
