Rosiglitazone and Exercise Training: Effects on HIV-Infected People With Insulin Resistance, Hypertriglyceridemia, and Adipose Tissue Maldistribution

Summary
Several complications have become prevalent in people living with HIV/AIDS, including increased blood sugar, increased blood fats and cholesterol, and fat tissue redistribution. The causes of these complications are not well understood and effective treatments have not been identified. We propose to test the efficacy and safety of 2 treatments for these complications in people living with HIV/AIDS: aerobic, weight lifting exercise training, and a new insulin-sensitizing agent called rosiglitazone (Avandia). Exercise and rosiglitazone have been effective and moderately safe when used in HIV-seronegative people with diabetes, but a specific trial is needed to test efficacy and safety in people living with HIV/AIDS.

Criteria
The research volunteers will consist of HIV-infected men and women treated with PI-based
HAART who have developed insulin resistance of impaired glucose homeostasis:

- fasting (8h) plasma glucose 110-126 mg/dL (6.1-7.1 mM) OR

- plasma glucose >140 (7.8 mM) 2 hours after a 75g-oral glucose load.

Although not required for enrollment, many of these volunteers will also have developed
trunk adipose tissue redistribution (defined as): trunk/appendicular adipose ratio using
whole-body DEXA >1.1 (men), >0.9 (women), or visceral adipose/total abdominal adipose
tissue (VAT/TAT) >0.40 using 1H-MRI imaging at the level of the umbilicus (~L3-L4
inter-vertebral space). Many will also have developed fasting hypertriglyceridemia
(>300mg/dL, >3.4 mM).

- Plasma viremia (Roche Amplicor assay) <5000 copies/ml OR a CD4 T-cell county >= 200
cells/ul for at least 3 months prior to enrollment.

- Stable on a PI-containing HAART regimen for at least 3 months prior to enrollment.

- 18-65 years of age

- Body mass index <= 34kg/m*2, total body fat <=35% of weight
