Growth hormone deficiency and human immunodeficiency virus.
Editor's note
This is a clinical review of growth-hormone deficiency in HIV, examining how the GH/IGF-1 axis is altered by HIV infection and its therapies, and tesamorelin is discussed substantively as a therapeutic option. The authors describe reduced spontaneous and stimulated GH secretion in HIV, especially with lipodystrophy, and note that tesamorelin (a GHRH analog) is associated with reduced visceral fat and is safer than high-dose recombinant human growth hormone. As a narrative review it frames rather than tests, but its treatment discussion is directly relevant to tesamorelin's mechanism and positioning. Read it as useful background on why the growth-hormone axis is disturbed in HIV and where tesamorelin fits, rather than as new efficacy data.
Plain-language abstract
This review examines how the growth-hormone system works in people with HIV. It explains that HIV, its treatments, and related body changes are linked to disrupted growth-hormone signaling, and that roughly a third of patients meet the definition of growth-hormone deficiency, especially those with abnormal fat distribution (lipodystrophy). The authors review why growth-hormone release is blunted and how fat accumulation contributes. They then discuss treatment approaches aimed at the growth-hormone/IGF-1 system, describing tesamorelin — a growth-hormone-releasing hormone analog — as a way to reduce excess deep belly fat that is safer and better tolerated than high-dose synthetic growth hormone. Because this is a summary of existing knowledge rather than a new experiment, it is best used to understand the biology and where tesamorelin fits, not as fresh proof of how well it works.
