There is an ongoing discussion regarding the impact of different antidiabetic drug classes on outcomes of interest among affected subjects. Dipeptidyl peptidase-4 (DPP-4) inhibitors have been placed at the epicenter, since the DPP-4 enzyme seems to be implicated in the disease pathogenesis. Herein we present an updated meta-analysis of observational studies addressing the risk of COVID-19 death among patients with T2DM on prior DPP-4 inhibitor treatment. We pooled data from 10 observational studies, showing that DPP-4 inhibitors produce a non-significant decrease in the risk for COVID-19-related death. However, when administered in the inpatient setting, DPP-4 inhibitors decrease the risk for COVID-19-related death by 50%.
