Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75. This item has not been peer reviewed.

[Auto, unreviewed; last sentences of abstract] This observational study demonstrated that the use of GLP-1 RAs, compared with DPP-4i, was associated with a lower incidence of tuberculosis, all-cause mortality, and gastrointestinal adverse events. These findings may have important implications for public health policy.

Abstract

Diabetes mellitus (DM) significantly increases the risk of developing active tuberculosis (TB). Poorly controlled diabetes, particularly with sustained hyperglycemia, is associated with higher TB incidence. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have become an important therapeutic option in the management of type 2 diabetes mellitus. GLP-1 RAs may also have immunomodulatory effects. Our study aims to evaluate the incidence of pulmonary TB among diabetic patients, and to examine whether GLP-1 RAs control modifies TB risk and mortality. We conducted a retrospective cohort study using the Global Collaborative Network of the TriNetX™ research platform from 152 participating health care organizations across the United States. We identified adult patients with diabetes mellitus who received either oral hypoglycemic agents (OHAs) containing GLP-1RA or dipeptidyl peptidase-4 inhibitor (DPP-4i) between January 1, 2016, and December 31, 2024. Diabetic patients receiving OHAs containing GLP-1 RA treatment had a significantly lower incidence of TB (HR: 0.55, 95% CI: 0.45-0.69), significantly reduced risk of death (HR: 0.52, 95% CI: 0.51-0.54), and significantly reduced risk of gastrointestinal and hepatobiliary disorders (HR: 0.77, 95% CI: 0.75-0.78), compared to those receiving DPP-4 inhibitor treatment. This observational study demonstrated that the use of GLP-1 RAs, compared with DPP-4i, was associated with a lower incidence of tuberculosis, all-cause mortality, and gastrointestinal adverse events. These findings may have important implications for public health policy.
