  • 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 (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.

    adiponectin.
  • Hemostatic Markers [ Time Frame: 6 months ]
    Tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) measured in serum.
  • Intramyocellular Lipid [ Time Frame: 6 months ]
    Intramyocellular lipid as measured by magnetic resonance (MR) spectroscopy of the calf.
  • Endogenous Growth Hormone Secretion [ Time Frame: 6 months ]
    Endogenous growth hormone concentrations will be measured by overnight freqent blood sampling, and a deconvolution algorithm will be used to characterize the pulsatility of secretion.
  • 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.
  • 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 as well as lipoprotein (a), Apoprotein B, Apoprotein A1, LDL particle size, LP-PLA2.
  • 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.
  • 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.

Effects of Growth Hormone Releasing Hormone in HIV
Effects of Growth Hormone Releasing Hormone on Fat Redistribution, Cardiovascular Indices, and Growth Hormone Secretion in HIV Lipodystrophy
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.
