How HIV integrase drugs affect weight and heart health differently by sex

SPPACE INSTI Study: Sex-specific Predictors, Pathways, And Cardiometabolic Effects of Weight Gain Associated with Integrase Strand-Transfer Inhibitors

NIH-funded research Emory University · NIH-11046593

This work looks at why people with HIV—especially women—often gain weight on integrase-based HIV medicines and how that weight gain may harm heart and metabolic health.

What this research studies

If you join, researchers will use long-running HIV cohort data and biological samples to compare people who switch to integrase strand-transfer inhibitors (INSTIs) with those who stay on other HIV medicines. They will track weight, body fat measures, blood pressure, blood sugar, and heart disease risk over time and analyze blood biomarkers and metabolites linked to insulin resistance and inflammation. The team will pay special attention to differences between women and men and how long weight changes last. Results aim to explain mechanisms and the longer-term cardiometabolic consequences of INSTI-associated weight gain.

Who could benefit from this research

Good fit: People living with HIV who are on antiretroviral therapy—particularly women considering switching to or already taking integrase inhibitor drugs—are the ideal candidates.

Not a fit: People without HIV or those not taking or switching to INSTI-class HIV drugs are unlikely to receive direct benefit from this work.

Why it matters

Potential benefit: Could help clinicians choose HIV medicines and manage weight, diabetes risk, and heart health more effectively for people with HIV, especially women.

How similar studies have performed: Prior clinical observations have consistently reported weight gain after starting INSTIs, but the sex-specific biological mechanisms and long-term cardiometabolic effects remain incompletely understood.
