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

Abstract

Objectives: 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.

Methods: 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.

Results: 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-naïve 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.

Conclusion: 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.
