Editor's note

This is a two-patient case report contrasting therapeutic paths for excess visceral abdominal fat in people living with HIV. Researchers described one non-obese patient whose increased waist circumference and lipids improved on tesamorelin (a GHRH analog that selectively lowers visceral fat), and a second, higher-BMI patient whose visceral fat persisted on an intermittently used GLP-1 receptor agonist until tesamorelin was added. Case reports are the weakest design tier — no control group, no randomization, and outcomes reflect individual clinical narratives rather than population estimates. Still, the cases illustrate a clinically meaningful point consistent with the broader tesamorelin evidence base: visceral adiposity can persist independent of BMI and may respond differently to a visceral-fat-selective agent than to a generalized weight-loss agent. Read it as illustrative context, not evidence of comparative efficacy.

Plain-language abstract

Doctors describe two adults with well-controlled HIV who both had extra fat around the abdomen but very different body types. The first, who was not obese, had a larger waistline and abnormal cholesterol; treatment with tesamorelin (a drug that selectively shrinks deep belly fat) was associated with a smaller waist, better lipids, and improved wellbeing. The second, who was obese, took a GLP-1 weight-loss medication only intermittently and kept fluctuating weight and stubborn belly fat; adding tesamorelin gave a more targeted reduction in deep abdominal fat. The authors use these two stories to argue that deep belly fat can exist regardless of overall weight and may need treatment aimed specifically at it rather than at general weight loss. Because this is just two patients with no comparison group, it illustrates a point rather than proving one approach works better than another.
