We aim to investigate cardiovascular effectiveness and safety of SGLT2i vs dipeptidyl peptidase-4 inhibitors (DPP4i) in older community-dwelling adults with diabetes by dementia status.<\/p>\n<p><strong>Methods<\/strong> \u2014 This population-based, target trial emulation cohort study used linkable administrative datasets of residents of Ontario, Canada. Eligible initiators of SGLT2i or DPP4i with diabetes aged \u226566 years (2016\u20132022) were stratified by dementia status and matched 1:1 on propensity score. The primary cardiovascular effectiveness outcome was composite of all-cause mortality or hospitalisation for ischaemic stroke, myocardial infarction or heart failure. We also investigated eight safety outcomes potentially related to SGLT2i. Incidence rate differences (IRDs) per 1000 person-years and the 95% CIs were estimated. Homogeneity in IRDs between strata was assessed using the Cochran\u2019s Q statistic. One year number needed to treat (NNT) or harm (NNH) was also estimated using the Aalen-Johansen estimator with death as a competing risk.<\/p>\n<p><strong>Results<\/strong> \u2014 We analysed 2481 pairs with dementia and 52,196 pairs without dementia. The absolute reduction in the composite effectiveness endpoint with SGLT2i vs DPP4i initiation was greater among those with dementia (IRD [95% CI] \u221261.1 [\u221278.2, \u221243.9]; NNT: 20), compared to no dementia (IRD \u221221.7 [\u221223.7, \u221219.7]; NNT: 43; homogeneity: p&lt;0.001). Across the individual effectiveness endpoints, SGLT2i vs DPP4i initiation in people with dementia was associated with reduced all-cause mortality (IRD \u221251.2 [\u221265.7, \u221236.7]; NNT: 25) and hospitalisation for heart failure (IRD \u221216.4 [\u221224.6, \u22128.2]; NNT: 99). For safety outcomes, SGLT2i vs DPP4i initiators with dementia showed less acute kidney injury (IRD \u221239.7 [\u221255.0, \u221224.4]; NNT: 76) and increased genital infection (IRD 9.7 [3.7, 15.6]; NNH: 64). The absolute increase in diabetic ketoacidosis (IRD 1.1 [0.7, 1.6] vs 5.9 [2.1, 9.8]; NNH: 785 vs 109; homogeneity: p=0.015) with SGLT2i was greater among those with dementia vs no dementia.<\/p>\n<p><strong>Conclusions\/interpretation<\/strong> \u2014 While SGLT2i might provide cardiorenal protection among those with dementia, closer monitoring may be warranted due to greater susceptibility to diabetic ketoacidosis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aims\/hypothesis \u2014 People with dementia are at a higher risk of inappropriate medication use; however, limited data inform clinical outcomes of sodium\u2013glucose cotransporter 2 inhibitor (SGLT2i) use in people with diabetes and comorbid dementia.
