Effects of Short-term Growth Hormone in HIV-infected Patients - Full Text View

Purpose

The purpose of this study is to examine the short-term effects of two different doses of growth hormone, compared to treatment with growth hormone releasing hormone, on the brain's secretion of growth hormone and the body's glucose metabolism. We hypothesize that growth hormone administration will alter the body's endogenous pulsatile growth hormone secretion and that higher dose growth hormone may decrease insulin sensitivity. We hypothesize that growth hormone releasing hormone will augment endogenous GH pulsatility and be neutral to insulin sensitivity.

Primary Outcome Measures:

Overnight Mean Growth Hormone Secretion After 2 Weeks of Study Drug [ Time Frame: after 2 weeks treatment ]
Serum was sampled for growth hormone concentrations every 20 minutes between 20:00 (8pm) and 07:40 (7:40am). Subjects in GH 6mcg/kg/day and GH 2mg daily groups received their final dose of study drug approximately 36 hours prior to start of sampling. Subjects in Growth Hormone Releasing Hormone group received their final dose of study drug approximately 8 hours prior to start of sampling.

Secondary Outcome Measures:

Insulin Sensitivity [ Time Frame: after two weeks treatment ]
insulin-stimulated glucose uptake as measured by euglycemic hyperinsulinemic clamp; "M" value (infusion rate with space correction, using method of DeFronzo) for the steady state between 100-120 minutes of clamp is given

Experimental: GH 2mg daily Recombinant human growth hormone 2mg SC once daily	Drug: Growth hormone Recombinant Human Growth Hormone (Teva pharmaceuticals), with one arm receiving 6mcg/kg SC once daily for two weeks and the other arm receiving 2mg SC once daily for two weeks Other Name: rhGH from Teva Pharmaceuticals
Experimental: Growth Hormone Releasing Hormone Growth Hormone Releasing Hormone (Tesamorelin) 2mg daily, injected subcutaneously, x 2 weeks	Drug: Growth Hormone Releasing Hormone Tesamorelin (GHRH) 2mg SC QD x 2 weeks

Detailed Description:

The primary objective of this study is to determine the differential effects of growth hormone releasing hormone (GHRH) vs. low dose physiologic growth hormone (GH) vs. higher dose GH treatment and withdrawal on endogenous overnight growth hormone secretion and pulsatility, as well as insulin-stimulated glucose uptake. Subjects with HIV-infection will be randomized to receive one of three treatments: GHRH 2mg/day, or growth hormone 6mcg/kg/day (physiologic "low" dose), or growth hormone 2mg/day ("higher" dose) for 2 weeks. At baseline and after two weeks of treatment, we will assess overnight growth hormone by frequent sampling as well as insulin stimulated glucose uptake by clamp. Subjects will then stop the treatment and will return for an identical assessment after a 2 week withdrawal period.
