INTRODUCTION: Dipeptidyl peptidase-4 (DPP-4) inhibitors reduce blood glucose in a dose-dependent manner, but the dose-dependent effect relationship between DPP-4 inhibitors and atherosclerosis has not been investigated. METHODS: Patients with type 2 diabetes mellitus (T2DM) treated with insulin were randomized to the sitagliptin (n = 137) or conventional treatment group (n = 137). In the sitagliptin group, each investigator was allowed to adjust the sitagliptin dose to avoid hypoglycemia...

Recent studies have demonstrated that stromal derived factor-1α (SDF-1α) is a substrate of dipeptidyl-peptidase-4 (DPP-4) inhibitors. It has also been shown that SDF-1α shares anti-apoptotic as well as nephroprotective properties and exerts a beneficial effect in the cardiovascular system. Therefore, the aim of this study was to estimate the effect of treatment with the DDP-4 inhibitor sitagliptin on SDF-1α levels in subjects with type 2 diabetes mellitus (T2D). Overall, 32 patients (16 males) with T2D, mean age (±SD) 67...

INTRODUCTION: We tested the hypothesis that dipeptidyl peptidase-4 (DPP-4) inhibitors are effective in preserving the β-cell function for long-term periods in patients with slowly progressive type 1 diabetes (SPIDDM) or latent autoimmune diabetes in adults (LADA). METHODS: In the present open-label, randomized, controlled trial, 14 non-insulin-requiring diabetic patients with glutamic acid decarboxylase autoantibodies (GADAb) were randomly assigned to receive either sitagliptin (S group) or pioglitazone (P group)...

PURPOSE: The objective of this clinical trial was to assess the efficacy and safety of omarigliptin monotherapy in young adult patients with type 2 diabetes mellitus (T2DM). Unexpected efficacy results in this trial led to a series of investigations that identified the use of prohibited medication by a substantial number of trial patients. METHODS: Patients with T2DM who were ≥18 to <45 years of age and either drug-naive or not on an antihyperglycemic agent for ≥12 weeks with inadequate glycemic control were randomized in a double-blind manner to receive omarigliptin 25 mg once weekly (n = 102) or placebo once weekly (n = 101) for 24 weeks...

Dipeptidyl peptidase-4 (DPP-4) inhibitors are relatively new class of anti-diabetic drugs. Some protective effects of DPP-4 on cardiovascular disease have been described independently from glucose-lowering effect. However, the detailed mechanisms by which DPP-4 inhibitors exert on endothelial cells remain elusive. The purpose of this research was to determine the effects of DPP-4 inhibitor on endothelial barrier function. Human umbilical vein endothelial cells (HUVECs) were cultured and exposed to hypoxia in the presence or absence of Diprotin A, a DPP-4 inhibitor...

Glucagon like peptide-1 (GLP-1) stimulates glucose-dependent insulin secretion. Dipeptidyl peptidase-4 (DPP-4) inhibitors, which block inactivation of GLP-1, are currently in clinical use for type 2 diabetes mellitus. Recently, GLP-1 has also been reported to have neuroprotective effects in cases of cerebral ischemia. We therefore investigated the neuroprotective effects of GLP-1 receptor (GLP-1R) agonist, exendin-4 (ex-4), after cerebral ischemia-reperfusion injury. Transient middle cerebral artery occlusion (tMCAO) was induced in rats by intracerebroventricular (i...

BACKGROUND: The association between dipeptidyl-peptidase IV inhibitors (DPP-4i) and heart failure (HF) remains unclear. In 1 randomized controlled trial and some observational studies, DPP-4i reportedly increased the risk of HF, but 2 other randomized controlled trials and observational studies have shown no such risk. Here, we evaluated the risk of HF and cardiovascular outcomes of DPP-4i compared with sulfonylureas. METHODS AND RESULTS: A population-based retrospective cohort study was conducted using the Korean Health Insurance Review and Assessment Service database from January 1, 2009, to December 31, 2015...

In randomized controlled trials (RCTs), more intensive glucose control in patients with type 2 diabetes leads to a modest (9%) reduction in major cardiovascular events (MACE), associated with a 20% reduction of kidney events and 13% reduction of eye events. The FDA issued guidance in 2008 led to the conduct of numerous cardiovascular outcomes (CVOT) trials to assess cardiovascular safety of new antihyperglycemic therapies in patients with type 2 diabetes. The results of these trials show that insulin glargine, three different dipeptidyl peptidase-4 (DPP-4) inhibitors (saxagliptin, alogliptin, and sitagliptin) and lixisenatide (a glucagon like peptide-1 receptor agonist) produce no significant difference in CVOT when compared with usual care or placebo...

The assessment of the cardiovascular safety profile of any newly developed antihyperglycemic drug is mandatory before registration, as a meta-analysis raised alarm describing a significant increase in myocardial infarction with the thiazolidinedione rosiglitazone. The first results from completed cardiovascular outcome trials are already available: TECOS, SAVOR-TIMI, and EXAMINE investigated dipeptidyl peptidase 4 (DPP-4) inhibitors, ELIXA, LEADER, and SUSTAIN-6 investigated glucagon-like peptide 1 (GLP-1) receptor agonists, and EMPA-REG OUTCOME and CANVAS investigated sodium-dependent glucose transporter 2 (SGLT-2) inhibitors...

BACKGROUND: Omarigliptin is a once-weekly (q.w.) oral DPP-4 inhibitor that is approved for the treatment of patients with type 2 diabetes mellitus (T2DM) in Japan. To support approval of omarigliptin in the United States, the clinical development program included a cardiovascular (CV) safety study. Subsequently, a business decision was made not to submit a marketing application for omarigliptin in the United States, and the CV safety study was terminated. Herein we report an analysis of data from that early-terminated study...

BACKGROUND: Clinical trials assessing the combination therapy of metformin plus dipeptidyl peptidase-4 inhibitors versus metformin plus Sulfonylureas on risk of cardiovascular disease, cardiovascular mortality and/or all-cause mortality in type 2 diabetes have shown conflicting results. We therefore evaluated the combination therapy on the risk of cardiovascular disease, cardiovascular mortality and/or all-cause mortality in type 2 diabetes. METHODS: A systematic search of Medline/PubMed (from 2000 to September 2015), EMBASE (from 2000 to September 2015), and Web of Knowledge (from 2000 to September 2015) for research articles published in English was carried out to examine how combination therapy affects the risk of CVD mortality and/or all-cause mortality in T2DM patients...

Objective The administration of glucocorticoids usually causes a mild increase in fasting glucose levels and a greater dose-dependent increase in postprandial values in patients without pre-existing diabetes mellitus. Patients with persistent hyperglycemia due to glucocorticoid therapy sometimes require insulin therapy, which might result in increased weight gain and more episodes of hypoglycemia, some of which are severe. On the other hand, scant evidence is available on the efficacy of oral hypoglycemic agents in treating glucocorticoid-induced diabetes...

Objective We investigated the efficacy, safety, and patient satisfaction of once-weekly DPP-4 inhibitors (DPP-4Is). Methods Either of two once-weekly DPP-4Is, trelagliptin or omarigliptin, was administered alone or in combination with other antidiabetic drugs in 80 outpatients with type 2 diabetes mellitus for 3 months. The HbA1c, glycoalbumin (GA), body weight, and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) scores were evaluated. Results Patients switching from other daily DPP-4Is (n=29) showed no significant changes in the HbA1c or GA levels...

Insulin secretagogues including sulfonylureas, glinides and incretin-related drugs such as dipeptidyl peptidase 4 (DPP-4) inhibitors and glucagon-like peptide-1 receptor agonists are widely used for treatment of type 2 diabetes. In addition, glucokinase activators and G-protein-coupled receptor 40 (GPR40) agonists also have been developed, although the drugs are not clinically usable. These different drugs exert their effects on insulin secretion by different mechanisms. Recent advances in β-cell signalling studies have not only deepened our understanding of insulin secretion but also revealed novel mechanisms of insulin secretagogues...

Introduction Novelties in the management of type 2 diabetes are dominated by the commercialisation of new glucose-lowering agents, which offer alternatives to older antidiabetic medications, and by the publication of several prospective placebo-controlled outcome trials, which demonstrated not only cardiovascular safety but also cardiovascular and renal protection with some new medications. Areas covered Updates regarding the use of glucose-lowering agents are discussed from a clinical point of view. Some new viewpoints concern older antidiabetic agents such as metformin, sulfonylureas and glitazones whose benefit-risk balance has been revisited, especially in high risk patients...

Incretins are hormones secreted into the blood stream from the gut mucosa in response to nutrient intake. They have been characterized based on their capacity to lower blood glucose levels. The more potent reduction of blood glucose coupled to a more intensive stimulation of insulin secretion, in response to oral glucose uptake, as compared to intravenous glucose infusion has further been termed the "incretin effect." As a prototype incretin hormone, the biology of glucagon-like peptide 1 (GLP-1) has been intensively studied...

The gastrointestinal tract - the largest endocrine network in human physiology - orchestrates signals from the external environment to maintain neural and hormonal control of homeostasis. Advances in understanding entero-endocrine cell biology in health and disease have important translational relevance. The gut-derived incretin hormone glucagon-like peptide 1 (GLP-1) is secreted upon meal ingestion and controls glucose metabolism by modulating pancreatic islet cell function, food intake and gastrointestinal motility, amongst other effects...

After failure of a monotherapy with metformin, dipeptidyl peptidase-4 inhibitors (gliptins) and sodium-glucose cotransporters type 2 (gliflozins) offer an alternative to the add-on of a sulphonylurea, especially in diabetic patients at risk of hypoglycaemia. The choice between a gliptin and a gliflozin may be guided by the individual patient characteristics : rather a gliptin in a patient without obesity or severe hyperglycaemia, in an elderly patient, with a frailty profile or with renal impairment; rather a gliflozin in an obese patient, with hypertension, hyperuricaemia, antecedents of cardiovascular disease (especially heart failure), without advanced renal insufficiency and with a low risk of urinary/genital infections or events linked to dehydration such as hypotension...
