Glucagon-like Peptide 1 Receptor Agonists Promote Weight Loss Among People With HIV.

Abstract

Weight gain and associated metabolic complications are increasingly prevalent among people with human immunodeficiency virus (PWH). Glucagon-like peptide 1 receptor agonists (GLP-1RAs) are incretin-based therapies for diabetes and weight management that have been shown to result in substantial weight loss; however, studies of their effects in PWH are limited. A retrospective single-center cohort study was conducted among PWH who were taking GLP-1RAs at the University of California, San Diego Owen Clinic between 1 February 2021 and 1 February 2023. Baseline clinical data were collected and changes in weight, body mass index (BMI), and hemoglobin A1C (A1C) before starting GLP-1RAs compared to the most recent clinic visit were calculated (with a minimum of 3 months follow-up time required). Logistic regression was performed to identify variables associated with >5% of total body weight loss. A total of 225 patients received on average 13 months of GLP-1RA therapy, with 85 (37.8%) achieving the maximum GLP-1RA dose. GLP-1RA therapy resulted, on average, in a weight loss of 5.4 kg, decrease in BMI by 1.8 kg/m2, and decrease in A1C by 0.6%. In the multivariable analysis, higher baseline BMI (odds ratio [OR], 1.10 [95% confidence interval {CI}, 1.03-1.16]), treatment duration of GLP-1RA therapy >6 months (OR, 3.12 [95% CI, 1.49-6.49]), and use of tirzepatide (OR, 5.46 [95% CI, 1.44-20.76]) were significantly more likely to be associated with >5% weight loss. Use of GLP-1RAs led to declines in weight, BMI, and A1C among PWH and offers an additional strategy to address weight gain and diabetes.
