The Effect of Empagliflozin and Metformin on Oxidative Capacity and Microvascular Reactivity of Skeletal Muscle in Patients With Type 2 Diabetes Mellitus
The purpose of the study is to compare the effect of empagliflozin, metformin, and the combination of both on the oxidative capacity of skeletal muscle and its microvascular reactivity in individuals with newly diagnosed type 2 diabetes. As the primary outcome, the investigators selected the change in skeletal muscle oxidative capacity and posed the following scientific question: Does empagliflozin significantly improve the oxidative capacity of skeletal muscle? The study will enroll 54 individuals with type 2 diabetes in a prospective, randomized, interventional, open-label study. Participants will be randomized into 3 equally sized groups: 1) a group receiving empagliflozin; 2) a group receiving metformin; and 3) a group receiving a combination of both drugs (empagliflozin and metformin). The investigators will analyze the clinical variables of the subjects, near-infrared spectroscopy (NIRS) measurements over the flexor digitorum superficialis muscle of the non-dominant arm at rest, after submaximal muscular work, and during transient brachial artery occlusion at specified time intervals (14 days, 1 month, 3 months, 6 months), as well as body composition, physical performance, and glycemic control following the pharmacological intervention.
