Plain Language Summary
Systematic review and meta-analysis of randomized controlled trials of tesamorelin versus placebo in adults with HIV, synthesizing outcomes across body composition (visceral fat, trunk fat), hepatic fat fraction, metabolic parameters (lipids, insulin resistance, IGF-1), and adverse events. Provides the highest-quality quantitative synthesis of tesamorelin's efficacy and safety in HIV lipodystrophy. Establishes the effect size estimates for tesamorelin's visceral fat reduction, hepatic fat improvement, and metabolic benefits in HIV—providing the most rigorous evidence base for clinical decision-making about tesamorelin use in HIV-associated lipodystrophy and informing its consideration for expanded indications.
Abstract
BACKGROUND: HIV-associated lipodystrophy leads to visceral fat accumulation, metabolic complications, body image concerns, medication non-adherence, and increased cardiovascular risks. We thought to assess the effects of Tesamorelin, a synthetic growth hormone-releasing hormone analogue, that has been proposed as a targeted therapy.
METHODS: We systematically searched PubMed, Embase, Scopus, Web of Science, and CENTRAL through July 2025 for randomized controlled trials (RCTs) evaluating Tesamorelin versus placebo in adults with HIV. Random-effects meta-analysis was applied. Outcomes included changes in body composition, hepatic and metabolic parameters, hormonal markers, and adverse events. Risk of bias was assessed with RoB 2.0, and certainty of evidence with GRADE.
RESULTS: Five RCTs evaluating Tesamorelin were included in the analysis. Tesamorelin was associated with significant reduction in visceral adipose tissue (MD=-27.71 cm², 95 % CI [-38.37, -17.06]; P < 0.001), trunk fat (MD=-1.18 kg, 95 % CI [-1.40, -0.96]; P < 0.001), limb fat (MD=-0.22 kg, 95 % CI [-0.35, -0.08]; P = 0.001), hepatic fat percentage (MD=-4.28 %, 95 % CI [-6.31, -2.24]; P < 0.001), and waist circumference (MD=-1.61 cm, 95 % CI [-2.28, -0.95]; P < 0.001). A significant increase in lean body mass was observed (MD=1.42 kg, 95 % CI [1.13, 1.71]; P < 0.001). However, no significant reductions in subcutaneous adipose tissue or BMI were observed. Tesamorelin showed no significant change in CD4 + T-cell counts. Tesamorelin was associated with adverse events, including arthralgia, myalgia, paresthesia, and injection-site reactions like erythema.
CONCLUSION: Tesamorelin improves body composition, hepatic fat, lean body mass, and IGF-1 levels in HIV-associated lipodystrophy, without serious side effects or perturbation of glucose.
