| 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.

| Study Summary: |
|
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.
