Purpose

HIV-infection and its treatment are often associated with an increase in belly fat, as well as abnormal cholesterol and problems metabolizing sugar. People with HIV infection and increased belly fat often have decreased growth hormone (GH) levels. Low GH levels may contribute independently to increased belly fat and to increased cardiovascular risk through effects on sugar metabolism, inflammation, and other mechanisms. Tesamorelin, a growth hormone releasing hormone (GHRH) analogue, has been shown to to reduce belly fat in patients with HIV-associated abdominal fat accumulation. However, the effects of tesamorelin on fat accumulation in the liver and muscle, sugar metabolism, and cardiovascular health are not yet known. The current study is designed to determine the effects of tesamorelin treatment on fat accumulation in the muscle and liver, insulin sensitivity and sugar metabolism, and markers of cardiovascular health including blood vessel thickness (carotid intima media thickness [cIMT]) and markers of inflammation in the body. The investigators hypothesize that tesamorelin will decrease fat accumulation in the liver and muscle and will decrease markers of inflammation, with either neutral or beneficial effects on glucose metabolism.

Primary Outcome Measures

  • Liver Fat [ Time Frame: 6 months ]
    Hepatic fat as measured by magnetic resonance (MR) spectroscopy, and expressed by normalizing lipid to water and expressing as a percent (lipid-to-water percent).
  • Visceral Adipose Tissue [ Time Frame: 6 months ]
    Change in visceral adipose tissue area as measured by single-slice computed tomography (CT) scan at the L4 vertebra.
Secondary Outcome Measures:
  • Intramyocellular Lipid [ Time Frame: 6 months ]
    Intramyocellular lipid (IMCL) as measured by magnetic resonance (MR) spectroscopy of the calf. Soleus IMCL normalized to creatinine (IMCL/Cr based on areas determined by spectroscopy) was measured. The change over 6 months is reported.
  • Endogenous Growth Hormone Secretion [ Time Frame: 6 months ]
    Endogenous growth hormone (GH) concentrations measured by overnight frequent blood sampling every 20 minutes. Mean overnight GH concentration is given.
  • Insulin Sensitivity [ Time Frame: 6 months ]
    In a subgroup of 1/2 of the subjects, euglycemic hyperinsulinemic clamp will be performed to assess insulin-stimulated glucose uptake. Insulin stimulated glucose uptake (M) calculated using the method of DeFronzo is shown.
  • HbA1c [ Time Frame: 6 months ]
    Hemoglobin A1c.
  • Insulin Like Growth Factor 1 (IGF-I) [ Time Frame: 6 months ]
    Insulin Like Growth Factor 1 (IGF-I).
  • Lipid Panel [ Time Frame: 6 months ]
    Fasting lipids. Triglyceride value is given.
  • Carotid Intimal Medial Thickness (cIMT) [ Time Frame: 6 months ]
    Carotid Intimal Medial Thickness (cIMT).
  • Glucose Tolerance [ Time Frame: 6 months ]
    Glucose tolerance as measured by standard oral glucose tolerance test. 2-hour glucose is given.
  • Adiponectin [ Time Frame: 6 months ]
    adiponectin.
  • Hemostatic Markers [ Time Frame: 6 months ]
    Tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) measured in serum.
