The dipeptidyl peptidase-4 inhibitor alogliptin improves glycemic control in type 2 diabetic patients undergoing hemodialysis.

摘要

The potent and selective dipeptidyl peptidase-4 (DPP-4) inhibitor alogliptin improves glycemic control in patients with type 2 diabetes through incretin hormone-mediated increases in both α- and β-cell responsiveness to glucose. In this study, the efficacy and safety of alogliptin in type 2 diabetic patients undergoing hemodialysis (HD) were evaluated.A prospective, open-label study of 30 patients (male/female: 24/6; mean age: 69.7 ± 1.7 years) with type 2 diabetes who were undergoing HD without insulin injection therapy was conducted. Patients were administered 6.25 mg/day alogliptin and efficacy and safety were determined by monitoring clinical and laboratory parameters during the 48-week study period.After 48 weeks, alogliptin had decreased postprandial plasma glucose levels from 212 ± 8 mg/dL baseline to 156 ± 7 mg/dL, hemoglobin A1c levels from 7.1 ± 0.2% baseline to 6.3 ± 0.2% and glycated albumin (GA) levels from 25.6 ± 0.6% baseline to 20.7 ± 0.4% (all p < 0.0001). Alogliptin efficacy did not differ according to median age or body mass index, but the GA reduction was significantly greater in the antidiabetic agents-na?ve group. The magnitude of GA reduction was baseline GA-dependent, being greater at higher baseline GA levels. No serious adverse effects, such as hypoglycemia or liver impairment, were observed in any patient.Alogliptin as monotherapy or in combination with other oral antidiabetic agents improved glycemic control and was generally well tolerated in patients with HD over a 48-week period.
