Dipeptidyl peptidase-4 (DPP-4) is known as a highly conserved type II transmembraneous glycoprotein widely distributed in a variety of tissues and cells, and expressed in the peripheral blood as a soluble form. It has been reported that DPP4 play a distinct role in the physiological and pathological processes, such as immune regulation, inflammatory reaction, cell adhesion, and cell apoptosis. DPP4 inhibitor showes an incredible effect on the control of blood glucose and it is thought as a newly-developed drug for diabetes, especially in regulation of post-prandial glycemia...

Little is known about the relationships between patient factors and the antihyperglycemic agents that have been prescribed as initial therapy by diabetes specialists for patients with type 2 diabetes. Moreover, there has been little clarification of the subsequent usage patterns and related factors that influenced the continuation or discontinuation of the drug or the addition of another drug. To provide information on these issues, we evaluated the clinical characteristics of Japanese patients with type 2 diabetes for whom different types of oral hypoglycemic agents (i...

OBJECTIVE: Randomized placebo-controlled trials have examined the cardiovascular (CV) effects of dipeptidyl peptidase-4 inhibitors (DPP-4i), but data on incidence relative to therapeutic alternatives are limited in the older US Medicare population. We compared the CV risk with DPP-4i relative to sulfonylureas (SU) and thiazolidinediones (TZD). METHODS: During 2007-2013, using Medicare beneficiaries >65 years we identified two new-user cohorts without the use of drugs being compared in the 6 months before initiation: DPP-4i versus SU and DPP-4i versus TZD...

BACKGROUND: Use of dipeptidyl peptidase-4 inhibitors (DPP4-i) for the treatment of type 2 diabetes (T2D) has been associated with a possible increase in the risk for heart failure (HF). B-type natriuretic peptide (BNP), which is both a biomarker of HF and a hemodynamically active hormone, is a substrate of DPP-4. We herein tested the acute effects of the DPP-4i linagliptin on BNP and NT-proBNP in a cross-over placebo-controlled trial in patients with T2D with and without chronic kidney disease (CKD)...

INTRODUCTION: A high hemoglobin glycation index (HGI) and glycated hemoglobin (HbA1c) level are associated with greater inflammatory status, and dipeptidyl peptidase-4 (DPP-4) inhibitors can suppress inflammation. We aimed to evaluate the relationship between HGI and the therapeutic effect of DPP-4 inhibitors. METHODS: This retrospective cohort study followed 468 patients with type 2 diabetes receiving DPP-4 inhibitor treatment for 1 year. Estimated HbA1c was calculated using a linear regression equation derived from another 2969 randomly extracted patients with type 2 diabetes based on fasting plasma glucose (FPG) level...

OBJECTIVE: Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) possess multiple bioactive isoforms that are rendered non-insulinotropic by the enzyme dipeptidyl peptidase-4 (DPP-4). Recently, some ELISA kits have been developed to specifically measure "active" GIP and GLP-1, but it is unclear if these kits can accurately quantify all bioactive forms. Therefore, it remains uncertain to what extent treatment with a DPP-4 inhibitor boosts levels of biologically active GIP and GLP-1...

Background -Calcification of the aortic valve leads to increased leaflet stiffness, and consequently to the development of calcific aortic valve disease (CAVD); however, the underlying molecular and cellular mechanisms of calcification remain unclear. Here, we identified that dipeptidyl peptidase-4 (DPP-4, also known as CD26) increases valvular calcification and promotes CAVD progression. Methods -We obtained the aortic valve tissues from humans and murine models (wild type and eNOS(-/-) mice), and cultured the valvular interstitial cells (VICs) and valvular endothelial cells (VECs) from the cusps...

BACKGROUND: Chronic kidney disease (CKD) is common in patients with type 2 diabetes mellitus (T2DM) and limits therapeutic options. Dipeptidyl peptidase-4 (DPP-4) inhibitors represent a novel class of oral glucose-lowering agents and are known to be safe and effective in the general population. METHODS: We searched Cochrane, EMBASE, and PubMed from the time of their inception until March 2015. We included randomized controlled trials analyzing the efficacy (change in hemoglobin A1C [HbA1C]) and safety of DPP-4 agents in individuals with reduced kidney function (estimated glomerular filtration rate <60 mL/min/1...

BACKGROUND AND PURPOSE: Dipeptidyl-peptidase (DPP)4 is expressed by resident renal cells, including glomerular cells. Dipeptidyl-peptidase 4 inhibitors (gliptins) exert albuminuria lowering effects, but the role of renal DPP4 as a pharmacological target has not been elucidated. To better understand the actions of gliptins, the effects of linagliptin on behaviour of immortalized human podocytes and mesangial cells have been evaluated. EXPERIMENTAL APPROACH: Expression of DPP4 was measured at both the mRNA and protein levels...

Saxagliptin/dapagliflozin fixed-dose combination tablets (Qtern(®)) are indicated in the EU for the improvement of glycaemic control in adults with type 2 diabetes mellitus (T2DM), either when treatment with metformin and/or a sulfonylurea plus a monocomponent of saxagliptin/dapagliflozin provides inadequate glycaemic control, or when the patient is already being treated with the free combination of saxagliptin + dapagliflozin. This narrative review summarizes pharmacological, efficacy and tolerability data relevant to the use of saxagliptin/dapagliflozin in this indication...

BACKGROUND: Dipeptidyl peptidase-4 (DPP-4) inhibitors improve glycemic control, and sitagliptin has been associated with a reduction in cardiovascular events. In vivo data suggest reduced platelet activation, and aggregation may play a role, and therefore, increased bleeding risk is possible. OBJECTIVE: Comparatively assess bleeding risks associated with DPP-4 inhibitors against standard treatment. METHODS: Exploratory analyses of adverse event reports (AERs) from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database (2004-2012 periods) were conducted...

Dipeptidyl peptidase-4 (DPP-4) inhibitors are oral anti-hyperglycemic drugs enabling effective glycemic control in type 2 diabetes (T2D). Despite DPP-4 inhibitors' advantages, the patients' therapeutic response varies. In this retrospective cohort study, 171 Taiwanese patients with T2D were classified as sensitive or resistant to treatment based on the mean change in HbA1c levels. Using an assumption-free genome-wide association study, 45 single nucleotide polymorphisms (SNPs) involved in the therapeutic response to DPP-4 inhibitors (P < 1 × 10-4) were identified at or near PRKD1, CNTN3, ASK, and LOC10537792...
