Impact of Glucagon-like Peptide 1 Receptor Agonists on Body Weight in People with HIV and Diabetes Treated with Integrase Inhibitors

Background/Objectives: We evaluated the effects of glucagon-like peptide-1 receptor agonists (GLP1-RAs) on body weight and metabolic parameters in people with HIV and diabetes (PWHD) receiving maintenance therapy with integrase inhibitor, using a real-world study design. Methods: PWHD on integrase inhibitors-based antiretroviral therapies for at least 6 months, and treated with GLP1-RAs for at least 3 months, were included in this retrospective study. The primary study outcome was the absolute and relative change in body weight, as assessed during routine outpatient visits. Secondary analyses included evaluating the impact of GLP1-RAs on additional metabolic parameters, such as serum glucose, glycated hemoglobin, and LDL-cholesterol. Results: A total of 25 PWHD (74% males, mean age 65 ± 7 years, with 16% having a body mass index > 30 Kg/m2) receiving GLP1-RAs-based antihyperglycemic therapy were identified from our hospital database. No significant effects of GLP1-RAs on body weight were observed (absolute reduction −1.9 ± 3.0 Kg; relative reduction −2.2 ± 3.7%). Treatment with GLP1-RAs was associated with a progressive and significant reduction in serum glucose and glycated hemoglobin, with no observed impact on LDL cholesterol. Conclusions: Long-term GLP1-RA treatment significantly reduced serum glucose and glycated hemoglobin in overweight PWHD with no effects on body weight.
