Newer Glucose-Lowering Drugs and Risk of Gout: A Network Meta-Analysis of Randomized Outcomes Trials.

ABSTRACT

PURPOSE: Previous studies have shown that newer glucose-lowering drugs (GLDs), such as sodium-glucose transport protein 2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs), and dipeptidyl peptidase 4 (DPP-4) inhibitors, may decrease the risk of gout, however, the evidence remains inconclusive. This study aimed to assess the association between newer GLDs and risk of gout. METHODS: We systematically searched electronic databases up to August 2023 to include randomized, placebo-controlled outcome trials that reported gout-related outcomes in participants with and without type 2 diabetes. A random effects network meta-analysis was conducted to estimate the risk ratio (RR) with 95% confidence interval (CI) to compare the effects of SGLT2 inhibitors, GLP-1RAs, and DPP-4 inhibitors on risk of gout. FINDINGS: This study included 22 trials involving 173,498 patients. Compared with placebo, SGLT2 inhibitors were significantly associated with decreased risk of gout (RR, 0.51; 95% CI, 0.29-0.91) while both GLP-1RAs and DPP-4 inhibitors have no significant effects on gout risk. There were no significant differences between SGLT2 inhibitors and GLP-1RAs (RR, 0.75; 95%CI, 0.31-1.82) and between GLP-1RAs and DPP-4 inhibitors (RR, 0.39; 95%CI, 0.14-1.10). IMPLICATIONS SGLT2 inhibitors may potentially prevent the risk of gout, however, both GLP-1RAs and DPP-4 inhibitors have neutral effects.
