Core Tip

Core Tip: Our study illuminated that there were no significant associations between in-hospital use of dipeptidyl peptidase-4 (DPP4) inhibitor (DPP4i) and 28-d all-cause mortality or multiorgan injury. In addition, the glucose control effects, inflammatory response, and associated adverse events were also comparable between patients in the DPP4i and non-DPP4i groups. These data provided direct clinical evidence to support the continuation of DPP4i therapy in diabetic patients with coronavirus disease 2019 (COVID-19). Moreover, this work paves the way for prospective studies and randomized controlled clinical trials on DPP4 inhibitor therapy for COVID-19.
