Background: Sodium glucose transporter 2 inhibitors (SGLT2-i) reduce renal and cardiovascular events in patients with type 2 diabetes (T2D) and their use is recommended by the 2020 KDIGO guidelines in patients with T2D and chronic kidney disease (CKD). The aim of this study is to estimate the proportion of patients with T2D and CKD in the US that should be treated with these agents for renal and cardiovascular protection.
Methods: We conducted a retrospective analysis of 2005-2018 National Health and Nutrition Examination Survey (NHANES) data. We focused on participants with a prior diagnosis of diabetes or that met diagnostic criteria for diabetes during the survey, with the exclusion of probable type 1 diabetic patients. Inclusion criteria for completed and ongoing renal and cardiovascular outcome trials in patients with CKD were applied.
Results: We estimated that 35.3% of patients with T2D in the US (projected to 8.96 million) should be treated with SGLT2-i according to the 2020 KDIGO guidelines. Moreover, 2.9-10.1% (projected to 0.75-2.55 million) met the inclusion criteria for dedicated kidney outcome trials, which were focused on a population of individuals with proteinuria.
Conclusions: About a third of patients with T2D in the US should be treated with an SGLT2-i. While compelling evidence of renal protection is present for patients with proteinuria, all patients with CKD obtain a cardiovascular benefit with this class of drugs.
