New GH secretagogues and potential usefulness in thalassemia.
Thalassemic patients today undergo intensive transfusion and chelation regimes that offer them prolonged survival and improved quality of life. Nevertheless, they face the consequences of chronic illness and therapies which affect multiple bodily functions. Endocrine derangements involve, among others, the GH-IGF-I axis with consequent impairment of growth. In such cases, GH release, as assessed with stimulation tests, may be normal whereas ultradian GH secretion seems to be subnormal. New GH secretagogues (GHRs) are agents that stimulate pituitary GH release by acting upon different receptors than the endogenous hypothalamic secretagogue, growth hormone-releasing hormone (GHRH). Examples are the growth hormone releasing peptides (GHRPs) GHRP-6, GHRP-1, GHRP-2, Hexarelin and the nonpeptidyl MK-0677. These can be administered by multiple routes, even per os or intranasally, thus obviating the need for injections. Their GH releasing capacity is more pronounced and prolonged than that of GHRH and their use is devoid of serious side effects. The most recently developed GHRs seem to be capable of producing sustained GH release in many cases and can thus be viewed as therapeutic candidates in cases of reduced GH secretion with intact pituitary, as seems to be the case in a group of thalassemic patients.
