[Is it reasonable to prescribe growth hormones in the elderly?].
During normal aging, there is a +/- 60% decrease of the endogenous GH secretion ("somatopause"). However it is safe to prescribe GH therapy only to those people who show a clear cut decrease of GH release as evidenced by low integrated 24 hr secretion and/or low plasma IGF-1. In our view, a complete clinical check up must also show, on the one hand, an abnormal decrease of the optimal quality of life and, on the other hand a willing to maintain a reasonable intellectual and physical activity in the absence of major clinical and biological abnormalities. The benefits are likely to be an increase of muscular strength and of exercise tolerance, a decrease of trabecular osteopenia, a decrease of abdominal obesity, an increase of immunocompetence and a general improvement of the "quality of life". A "pharmacological" prescription is contra-indicated whereas very low dose regimen could induce, through feed back mechanism, a putative decrease of endogenous GH-RH (and GHRPs?) function whose deleterious psychoneuroendocrine effects remain to be demonstrated.
