  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 ] [ Designated as safety issue: No ]
    Hepatic fat as measured by magnetic resonance (MR) spectroscopy.

  • Visceral Adipose Tissue [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    Intramyocellular lipid as measured by magnetic resonance (MR) spectroscopy of the calf.

  • Endogenous growth hormone secretion [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: Yes ]
    Hemoglobin A1c.

  • Insulin Like Growth Factor 1 (IGF-I) [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    Insulin Like Growth Factor 1 (IGF-I).

  • Lipid panel [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Fasting lipids as well as lipoprotein (a), Apoprotein B, Apoprotein A1, low density lipid (LDL) particle size, lipoprotein-associated phospholipase A2 (Lp-PLA2).

  • Carotid Intimal Medial Thickness (cIMT) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Carotid Intimal Medial Thickness (cIMT).

  • Glucose tolerance [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Glucose tolerance as measured by standard oral glucose tolerance test.

  • adiponectin [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    adiponectin.

  • hemostatic markers [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) measured in serum.
