Comparative Effectiveness of Sodium–Glucose Cotransporter-2 Inhibitors for Recurrent Gout Flares and Gout-Primary Emergency Department Visits and Hospitalizations : A General Population Cohort Study

Ann Intern MedPublished Propensity score-matched, new-user cohort study

Authors' conclusion

Among patients with gout, SGLT2is may reduce recurrent flares and gout-primary ED visits and hospitalizations and may provide cardiovascular benefits.

Study context

Population
Patients with gout and type 2 diabetes, general population database, 1 January 2014 to 30 June 2022
Exposure
SGLT2i initiation vs DPP-4i initiation
Outcome
Recurrent gout flare counts ascertained by emergency department (ED), hospitalization, outpatient, and medication dispensing records
Methodological detailsoverlap weighting (sensitivity analysis), Poisson and Cox proportional hazards regressions
  • Overlap weighting (sensitivity analysis)
  • Poisson and Cox proportional hazards regressions

Main finding

As reported in the abstract

Recurrent gout flare rate (events per 1000 person-years)
SGLT2i vs DPP-4iRelative risk (95% CI)
After propensity score matching
0.66(0.57–0.75)
SGLT2i vs DPP-4iRate difference, per 1000 person-years (95% CI)
Recurrent gout flare rate (events per 1000 person-years)
−27.4(−36.0 to −18.7)

Observational data: associations, not effects.
