Effect of Saxagliptin on Endothelial Function in Patients with Type 2 Diabetes: A Prospective Multicenter Study.

ABSTRACT: The dipeptidyl peptidase-4 inhibitor saxagliptin is a widely used antihyperglycemic agent in patients with type 2 diabetes. The purpose of this study was to evaluate the effects of saxagliptin on endothelial function in patients with type 2 diabetes. This was a prospective, multicenter, interventional study. A total of 34 patients with type 2 diabetes were enrolled at four university hospitals in Japan. Treatment of patients was initially started with saxagliptin at a dose of 5?mg daily. Assessment of endothelial function assessed by flow-mediated vasodilation (FMD) and measurement of stromal cell-derived factor-1? (SDF-1?) were conducted at baseline and at 3 months after treatment with saxagliptin. A total of 31 patients with type 2 diabetes were included in the analysis. Saxagliptin significantly increased FMD from 3.1?±?3.1% to 4.2?±?2.4% (P?=?0.032) and significantly decreased total cholesterol from 190?±?24?mg/dL to 181?±?25?mg/dL (P?=?0.002), glucose from 160?±?53?mg/dL to 133?±?25?mg/dL (P?

Project description:IntroductionDulaglutide, a long-acting glucagon-like peptide-1 receptor agonist (GLP-1RA), became available in Italy in April 2016. The aim of ANDREW (Active Notes on Dulaglutide in the REal World), a multicenter, prospective, observational study, was to evaluate glycemic control and weight (co-primary outcomes) for up to 24 months in the real-life setting in consecutive outpatients with type 2 diabetes (T2D) who initiated dulaglutide. Co-secondary outcomes were durability of treatment effects on both glycated hemoglobin (HbA1c) and body weight.MethodsOverall, 1584 subjects (696 women, 888 men) with T2D (mean age [± standard deviation] 61.7 ± 10.2 years; mean T2D duration 9.9 ± 6.9 years) were treated with dulaglutide (0.75 or 1.5 mg once weekly) between April 2016 and December 2019.ResultsA total of 1130 patients completed 12 months of follow-up, while 170 patients interrupted treatment before the 12-month endpoint. At 12 months, average HbA1c and average fasting plasma glucose (FPG) were significantly lower compared to baseline levels (- 10 mmol/mol and - 24.9 mg/dL, respectively), as were body weight (- 3.4 kg) and waist circumference (- 3.3 cm) values (all p < 0.0001). Among subjects that completed 24 months of follow-up (n = 270), the rapid decline in HbA1c and FPG values in the first 12 months was followed by stabilization in the following 12 months (p value for 12-24 months trend: 0.4 and 0.6, respectively).ConclusionsDulaglutide is an effective drug for the treatment of T2D that is administered once weekly using a simple auto-injector device. Real-life data confirm the observations in randomized controlled trials that persistent treatment with dulaglutide may help patients with T2D achieve an improvement in some metabolic features and in body weight. It is important that the benefits of therapy with dulaglutide, i.e., the effects of the "glycemic" and the so-called "extra-glycemic" actions of GLP-1RAs, are supported by diabetes care teams emphasizing the need for patients to maintain a healthy lifestyle.

Project description:AimsType 2 diabetes is associated with endothelial dysfunction leading to cardiovascular disease. CD34+ endothelial Progenitor Cells (EPCs) are responsible for endothelial repair and neo-angiogenesis and can be used as a cardiovascular disease risk biomarker. This study investigated whether the addition of saxagliptin, a DPP-IV inhibitor, to metformin, may reduce cardiovascular disease risk in addition to improving glycemic control in Type 2 diabetes patients.MethodsIn 12 week, double-blind, randomized placebo-controlled trial, 42 subjects already taking metformin 1-2 grams/day were randomized to placebo or saxagliptin 5 mg. Subjects aged 40-70 years with diabetes for < 10 years, with no known cardiovascular disease, BMI 25-39.9, HbA1C 6-9% were included. We evaluated EPCs number, function, surface markers and gene expression, in addition to arterial stiffness, blood biochemistries, resting energy expenditure, and body composition parameters. A mixed model regression to examine saxagliptin vs placebo, accounting for within-subject autocorrelation, was done with SAS (p < 0.05).ResultsAlthough there was no significant increase in CD34+ cell number, CD31+ cells percentage increased. Saxagliptin increased migration (in response to SDF1α) with a trend of higher colony formation count. MNCs cytometry showed higher percentage of CXCR4 double positivity for both CD34 and CD31 positive cells, indicating a functional improvement. Gene expression analysis showed an upregulation in CD34+ cells for antioxidant SOD1 (p < 0.05) and a downregulation in CD34- cells for IL-6 (p < 0.01). For arterial stiffness, both augmentation index and systolic blood pressure measures went down in saxagliptin subjects (p < 0.05).ConclusionSaxagliptin, in combination with metformin, can help improve endothelial dysfunction in early diabetes before macrovascular complications appear. Trial registration Trial is registered under clinicaltrials.gov, NCT02024477.
