Proteomic Signatures and Blood Adenosine Triphosphate Levels as Markers of Empagliflozin Efficacy in Type 2 Diabetes Mellitus and Heart Failure
Abstract
Abstract Empagliflozin, a sodium-glucose cotransporter 2 inhibitor, is approved for the treatment of type 2 diabetes mellitus and heart failure. Its known ability to enhance mitochondrial adenosine triphosphate production and improve cardiac function led us to investigate whether blood adenosine triphosphate levels could serve as a predictive biomarker for treatment response. This prospective study included 120 patients from Kyrgyzstan: 49 with type 2 diabetes mellitus, 43 with heart failure, and 28 with both type 2 diabetes mellitus and heart failure. The mean age of the study population was 63.9±7.1 years, with no significant age difference between groups. Patients received oral empagliflozin at a dose of either 10 or 25 mg daily for 12 weeks. Adenosine triphosphate activity was measured in erythrocytes from whole blood samples before and after treatment. In vitro assays were also performed, incubating patient blood samples with empagliflozin at concentrations of 0.1, 1, and 10 µM. In patients with type 2 diabetes mellitus, empagliflozin significantly reduced body mass index ( p =0.001), though HbA1c levels remained unchanged. Among heart failure patients, treatment resulted in a significant increase in left ventricular ejection fraction ( p =0.028) and a decrease in B-type natriuretic peptide levels ( p =0.01). Blood adenosine triphosphate concentrations increased significantly following empagliflozin treatment in both type 2 diabetes mellitus and heart failure groups.…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 120 participants or records.
