BACKGROUND: Sodium Glucose Transporter 2 inhibitor (SGLT-2i) medications reduce inflammation, improve glycemic control, and impart weight loss, all of which may play a role in chronic obstructive pulmonary disease (COPD) pathophysiology.
OBJECTIVES: The primary objective of our study was to explore the incidence of COPD exacerbation in patients with diabetes and COPD on SGLT-2i medications. The secondary objective was to assess the impact of SGLT-2i medications on COPD exacerbations needing hospitalization, ICU admission, and mechanical ventilation.
METHODS: This was a retrospective cohort analysis of COPD patients with diabetes enrolled in the COPD registry at a Mid-west Tertiary care teaching hospital from January 1, 2022, to December 31, 2022. We used Slicer-Dicer, a self-service cohort exploration tool embedded in EPIC for data extraction.
RESULTS: We had 31,411 patients registered with the COPD registry during the study period. Of these, 18,713 had diabetes, and 1295 patients were on SGLT-2i medication. The incidence of COPD exacerbation, including severe COPD exacerbation needing hospitalization, was significantly lower in the SGLT-2i medication group (3.16% vs 18.3%, p < 0.05; 1.2% vs 5.04%, p < 0.05). Also, there was a non-significant trend suggesting that the incidence of COPD exacerbation needing intensive care unit admission and intubation was lower in the SGLT-2i medication group (0.07% vs 3.4%; 0 vs 0.04%). SGLT-2i medication use was associated with reduced incidence of COPD exacerbation irrespective of underlying control of diabetes.
CONCLUSIONS: Our study suggests possible role of SGLT-2i in preventing COPD exacerbation. Randomized trials are needed in the future to confirm or refute these findings.
