Integrase Strand Transfer Inhibitors Play the Main Role in Greater Weight Gain Among Men With Acute and Early HIV Infection.

ABSTRACT:

Background

The predictors of weight gain remain unclear in people with acute and early HIV infection (AEH).

Methods

Eligible antiretroviral-naïve men diagnosed with AEH from January 1, 2000, to December 31, 2019, were enrolled in an observational cohort study at the University California, San Diego. The study used multivariable mixed-effect linear regression models to analyze differences in the rate of weight gain over time between participants receiving early vs deferred antiretroviral therapy (ART) treatment, low vs high baseline CD4 count and HIV RNA, and different classes of ART.

Results

A total of 463 participants were identified, with mean CD4 cell count of 507 cells/?L and log HIV RNA of 5.0 copies/mL at study entry. There was no difference in the rate of weight gain between participants who did and did not receive ART within 96 weeks of incident HIV infection. Neither a baseline CD4 count of <350 cells/?L nor a baseline HIV RNA of >100 000 copies/mL was a predictor of weight gain. Compared with persons taking non-nucleoside reverse transcriptase inhibitor-based regimens, those who received integrase strand transfer inhibitor (INSTI)-based regimens showed greater weight gain over time.

Conclusions

Neither baseline CD4 count and HIV RNA nor early ART was associated with weight change in the first 96 weeks following incident HIV infection. Use of INSTI-based regimens represented a major driver of weight gain in men who initiated ART with relatively higher CD4 cell counts.

Project description:BackgroundStudies have shown an increase in weight among people living with human immunodeficiency virus (PLWH) who have also initiated integrase strand transfer inhibitors (INSTI). However, limited data are available regarding comparison of these changes with other antiretroviral regimens.ObjectiveTo assess differences in weight gain after initiating INSTI- versus protease inhibitor (PI)-based regimens among treatment-naïve PLWH overall, and among a subpopulation of females only.MethodsThis retrospective, observational cohort study included data from the Optum ® deidentified Electronic Health Record (EHR) database. Adult PLWH who initiated INSTI- or PI-based regimens between March 1, 2016 and June 30, 2018 (index date was the first INSTI or PI prescription in this period) with ≥12-month baseline and follow-up periods, ≥1 weight measure during each period, and no prior antiretroviral use were included. The last weight measure between 12 months pre- and 30 days post-index was defined as baseline weight; the last measure between the months 4 and 12 of follow-up was defined as post-weight. Weight change was reported as absolute change and proportion of patients with increased weight. Cohorts were balanced using propensity score (PS) matching. Multivariable models were used to compare outcomes of interest.ResultsAfter matching, 1588 patients were included (794 per cohort). At baseline, 46% were <50 years old, 26% were females, 12% had Type II diabetes and 30% had hypertension (mean baseline weight: INSTI: 83 kg (183 lb), PI: 82 kg (181 lb); P = 0.3). The mean time to follow-up weight measure was 9.3 months; INSTI initiators had a 1.3 kg (2.9 lb) greater mean weight gain (95% CI: 0.5-2.0), and a higher proportion with ≥5% weight gain (30.7% vs 26.1%; [OR=1.3, 95% CI: 1.0-1.6]) than PI initiators. Differences in weight gain between regimens were larger among females; female INSTI initiators had a 2.5 kg (5.3 lb) greater mean weight gain (95% CI: 0.7-4.2) and a higher proportion with ≥5% weight gain (37.5% vs 26.4%; OR=1.7; 95% CI [1.1-2.6]) than PI initiators.ConclusionIn a real-world setting, compared to PI-based regimens, INSTI-based regimens are associated with greater weight gain for treatment-naïve PLWH. This study may inform HIV treatment choice for health care providers.
