Metabolic Abnormalities in HIV-infected Persons
This purpose of this study is to examine the relationship between insulin resistance and changes in body fat distribution in HIV-infected persons. This study measures insulin sensitivity, abdominal fat, and intramuscular fat in HIV-infected persons and examines the effect of an anti-diabetic drug (metformin or pioglitazone) on insulin sensitivity and body fat in this population.

Metformin at a dose of one 500mg tablet twice a day with meals for one week, after which the dose will increase to 500 mg three times a day with meals for the remaining 11 weeks of the study.
Pioglitazone at a dose of one 30 mg tablet once per day for the 12 weeks of the study.

Although HIV antiretroviral medications have helped patients live longer, they have also been associated with side effects including insulin resistance and changes in body fat distribution. Changes in body fat distribution associated with HIV antiretroviral medications may result in increased fat in the abdomen, neck, and upper back, which is often called central fat deposition. HIV antiretroviral medications may also result in loss of fat in legs, arms, and face, which is often called peripheral fat atrophy.
Insulin resistance is a pre-disease condition that often leads to diabetes after 10 to 20 years. Insulin is a hormone made by the body that tells the body to store glucose in muscle and fat. People with insulin resistance often need more insulin to store the same amount of glucose. Both insulin resistance and changes in fat distribution in HIV-infected persons are areas of active research because they are both associated with an increased risk of heart disease.
This study examines the relationship between insulin resistance and changes in body fat distribution in HIV-infected persons. This study will recruit both HIV-infected and uninfected persons. The investigators will compare findings between HIV-infected persons with central fat deposition and HIV-infected persons with peripheral fat atrophy, as well as between HIV-infected and uninfected persons.
This study involves taking a drug that has been approved by the U.S. Food and Drug Administration (FDA) for use in humans for a period of 3 months.
