SGLT-2 inhibitors(SGLT-2Is)have significantly improved cardio-renal outcomes and are preferred agents in people with cardiovascular diseases,heart failure,and diabetic kidney disease.Similarly,GLP-1 receptor agonists(...SGLT-2 inhibitors(SGLT-2Is)have significantly improved cardio-renal outcomes and are preferred agents in people with cardiovascular diseases,heart failure,and diabetic kidney disease.Similarly,GLP-1 receptor agonists(GLP-1RAs)have significantly improved atherosclerotic cardiovascular outcomes.To this end,DPP-4 inhibitors(DPP-4Is)are cardiac-neutral drugs.While long-acting GLP-1RAs have shown a favorable HbA1c lowering compared to DPP-4Is,there is no clinically meaningful HbA1c lowering difference between SGLT-2Is vs DPP-4Is.Moreover,the glucose-lowering potential of SGLT-2Is gets compromised with a progressive decline in renal functions,unlike DPP-4Is.Furthermore,the HbA1c lowering potential of DPP-4Is is favorable in people with T2DM having a modest baseline HbA1c(8.0%-8.5%)compared with SGLT-2Is which lowers HbA1c larger in a background of higher baseline HbA1c(>8.5%-9.0%).These findings suggest that the role of DPP-4Is in the management of type 2 diabetes mellitus cannot be completely ignored even in the era of SGLT-2Is.展开更多

Material and Methods: In this research we have retrospectively reviewed the records of 80 patients who had added dipeptidyl peptidase-4 inhibitors (40 sitagliptin and 40 vildagliptin) to their ongoing therapies. Patients’ values of inflammation at the beginning of this process were taken as initial values, while values at the end of this process were considered as final values. Results: A total of 80 patients [38.8% (n = 31) of the patients were male, while 61.3% (n = 49) were female] enrolled in the study. When the whole group was evaluated, the mean age was 56.1 ± 9.7 years. The median follow-up time of the patients with DPP-4 inhibitors was 18 (2 - 64) months. The mean MPV value was measured as 8.79 ± 1.71 fL before DPP-4 inhibitors and it was 10.06 ± 1.42 fL after the follow-up period (p < 0.001). The median value serum GGT was 30.5 (13 - 194) U/L before DPP-4 inhibitor and 29.5 (12 - 112) U/L at the end (p = 0.048). The mean uric acid level before the use of di-peptidyl peptidase-4 inhibitors was 4.7 ± 1.6 mg/dL, and this level was 5.0 ± 1.5 mg/dL after the follow-up period (p = 0.048). Conclusion: In this study, it was observed that MPV and GGT levels were improved by dipeptidyl peptidase-4 inhibitors in long-term.展开更多

文摘This editorial introduces the potential of targeting macrophage function for diabetic cardiomyopathy(DCM)treatment by dipeptidyl peptidase-4(DPP-4)inhibitors.Zhang et al studied teneligliptin,a DPP-4 inhibitor used for diabetes management,and its potential cardioprotective effects in a diabetic mouse model.They suggested teneligliptin administration may reverse established markers of DCM,including cardiac hypertrophy and compromised function.It also inhibited the NLRP3 inflammasome and reduced inflammatory cytokine production in diabetic mice.Macrophages play crucial roles in DCM pathogenesis.Chronic hyperglycemia disturbs the balance between pro-inflammatory(M1)and antiinflammatory(M2)macrophages,favoring a pro-inflammatory state contributing to heart damage.Here,we highlight the potential of DPP-4 inhibitors to modulate macrophage function and promote an anti-inflammatory environment.These compounds may achieve this by elevating glucagon-like peptide-1 levels and potentially inhibiting the NLRP3 inflammasome.Further studies on teneligliptin in combination with other therapies targeting different aspects of DCM could be suggested for developing more effective treatment strategies to improve cardiovascular health in diabetic patients.
