Canagliflozin (CAN) regulates intracellular glucose metabolism by targeting sodium-glucose co-transporter 2 (SGLT2) and intracellular glucose metabolism affects inflammation. In this study, we hypothesized that CAN might exert anti-inflammatory effects. The anti-inflammatory effects and action mechanisms of CAN were assayed in lipopolysaccharide (LPS)-induced RAW264.7 and THP-1 cells and NIH mice. Results showed that CAN significantly inhibited the production and release of interleukin (IL)-1, IL-6, or tumor necrosis factor-α (TNF-α) in the LPS-induced RAW264...

INTRODUCTION: In the SAVOR-TIMI trial, the risk of heart failure (HF) was increased by 27% in T2D patients randomized to the dipeptidyl peptidase-4 inhibitor (DPP4i) saxagliptin. Other studies have provided inconsistent results regarding this association. Herein, we performed a pharmacovigilance analysis of the rate of HF associated with DPP4is, focusing on stimulated reporting and moderation by drug-drug interactions. METHODS: We mined the FDA adverse event (AE) reporting system (FAERS) from 2004q1 to 2017q3, including a total of 9906,642 AE reports...

The final goal in the management of patients with type 2 diabetes (T2D) is reduction in cardiovascular (CV) complications and total mortality. Various factors including hyperglycemia contribute to these complications and mortality directly and indirectly. In recent years, large-scale CV outcome trials with new antidiabetic medications, such as dipeptidyl peptidase-4 (DPP4) inhibitors, glucagon-like peptide-1 (GLP1) receptor agonists, and sodium glucose cotransporter-2 (SGLT2) inhibitors, have been completed...

BACKGROUND: Diabetic ketoacidosis (DKA) is a serious complication of diabetes seen commonly in autoimmune Type 1 diabetes mellitus (DM), however patients with Type 2 diabetes are also at risk. Diabetic ketoacidosis may be precipitated by the catabolic stress of acute illness such as trauma, surgery, or infections. Recent studies have suggested that sodium glucose cotransporter-2 (SGLT-2) inhibitors precipitate DKA in Type 2 diabetes. We present a case series of four patients on SGLT-2 inhibitors who presented with DKA...

Sodium glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP4) inhibitors have complementary mode of action. For the meta-analysis comparing the efficacy and safety between SGLT2 inhibitor plus DPP4 inhibitor (SGLT2i/DPP4i) and placebo plus DPP4 inhibitor (PCB/DPP4i) in patients with type 2 diabetes mellitus (T2DM), we selected randomized controlled trials from electronic databases by predefined criteria. The primary outcome of interest was the change in glycated hemoglobin A1c (HbA1c) from baseline...

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are an emerging class of oral hypoglycaemic agents with therapeutic benefits beyond better glycaemic control. A major concern of the sodium-glucose co-transporter 2 inhibitors is their propensity to cause euglycaemic ketoacidosis in the peri-operative period and the potential for this critical diagnosis to be delayed or missed entirely. This review attempts to collate the case reports of sodium-glucose co-transporter 2 inhibitor ketoacidosis associated with surgery to highlight and put a perspective on this peri-operative issue...

A novel glucose transporter, the sodium glucose cotransporter 2 (SGLT2), has been demonstrated to contribute to the demand for glucose by pancreatic and prostate tumors, and its functional activity has been imaged using a SGLT specific PET imaging probe, α-methyl-4-[F-18]fluoro-4-deoxy-D-glucopyaranoside (Me-4FDG). In this study, Me-4FDG PET was extended to evaluate patients with high-grade astrocytic tumors. Me-4FDG PET scans were performed in four patients diagnosed with WHO Grade III or IV astrocytomas and control subjects, and compared with 2-deoxy-2-[F-18]fluoro-D-glucose (2-FDG) PET and magnetic resonance imaging (MRI) of the same subjects...

Obesity-related heart failure with a preserved ejection fraction (HFpEF) is an important phenotype prevalent in the community, especially in people with metabolic disorders (e.g., dyslipidemia, diabetes). These individuals exhibit a marked expansion of plasma volume, but ventricular distensibility is limited, most likely as a result of cardiac microvascular rarefaction acting in concert with myocardial and pericardial fibrosis. Consequently, the increase in plasma volume causes a disproportionate increase in cardiac filling pressures, leading to heart failure, even though systolic ejection is not impaired...

The prevalence of heart failure (HF) in the diabetic population has rapidly increased over the past 2 decades, triggering research about the impact of oral anti-diabetic medications on it. Unfortunately, not all success at the bench in preclinical experiments has translated to success at the bedside. On the other hand, recent promising clinical data from oral SGLT2 inhibitors mainly lack mechanistic explanation from experimental studies. Hence, it is critical to understand the lessons learned from prior translational studies to gain a better knowledge of the mechanisms of oral anti-diabetic drugs in HF...

The coexistence of type 2 diabetes mellitus (T2DM) and heart failure (HF), either with reduced (HFrEF) or preserved ejection fraction (HFpEF), is frequent (30-40% of patients) and associated with a higher risk of HF hospitalization, all-cause and cardiovascular (CV) mortality. The most important causes of HF in T2DM are coronary artery disease, arterial hypertension and a direct detrimental effect of T2DM on the myocardium. T2DM is often unrecognized in HF patients, and vice versa, which emphasizes the importance of an active search for both disorders in the clinical practice...

BACKGROUND AND AIMS: Leukocytosis, particularly monocytosis, has been shown to promote atherosclerosis in both diabetic and non-diabetic mouse models. We previously showed that hyperglycemia independently promotes monocytosis and impairs the resolution of atherosclerosis. Since patients with chronic diabetes often develop dyslipidemia and also have increased risk for atherosclerosis, we sought to examine how controlling blood glucose affects atherosclerosis development in the presence of severe hyperlipidemia...

Cardiac fibrosis is a major pathological manifestation of diabetic cardiomyopathy (DCM), which leads to cardiac remodeling, dilated cardiomyopathy and congestive heart failure. Human cardiac fibroblasts (HCF) constitute the predominant cell type in the heart and matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are also involved in cardiac fibrosis. However, it is unclear whether high glucose levels affect the expression of MMPs and TIMPs in HCF. Sodium‑glucose cotransporter (SGLT) inhibitors have been developed as therapeutic agents and the anti‑DCM effect of SGLT inhibitors has been demonstrated by previous studies...

Human sodium-dependent glucose co-transporter 2 (hSGLT2) is a crucial therapeutic target in the treatment of type 2 diabetes. In this study, both comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were applied to generate three-dimensional quantitative structure-activity relationship (3D-QSAR) models. In the most accurate CoMFA-based and CoMSIA-based QSAR models, the cross-validated coefficients (r2 cv ) were 0.646 and 0.577, respectively, while the non-cross-validated coefficients (r2 ) were 0...

BACGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 inhibitors (DPP4I) are used to treat type 2 diabetes (T2DM). DPP4 inhibitors (DPP4) attenuate Nlrp3 inflammasome activation in the kidney. SGLT2 inhibition reduces inflammation and attenuates the progression of diabetic nephropathy (DN). The effects of dapagliflozin (Dapa) on the activation of the Nlrp3 inflammasome and the combined effect of SGLT2 and DPP4 on T2DM-induced inflammasome activation and progression of DN have not been previously studied...

Background: The benefits of sodium glucose cotransporters 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus include plasma glucose control, reduction in body weight and blood pressure, and low risk of hypoglycemia, although they may also cause genitourinary infections, polyuria, or volume depletion. It is not clear whether dapagliflozin, an SGLT2 inhibitor, improves treatment satisfaction among patients in a comprehensive way despite the negative side effects. This study assessed the effect of dapagliflozin on glycosylated hemoglobin (HbA1c), body weight, and treatment satisfaction in overweight patients with type 2 diabetes mellitus treated with oral hypoglycemic agents...

Clinical and experimental studies have shown that sodium glucose co-transporter 2 inhibitors (SGLT2i) contribute to the prevention of diabetic kidney disease progression. In order to clarify its pharmacological effects on the molecular mechanisms underlying the development of diabetic kidney disease, we administered different doses of the SGLT2i, ipragliflozin, to type 2 diabetic mice. A high-dose ipragliflozin treatment for 8 weeks lowered blood glucose levels and reduced urinary albumin excretion. High- and low-dose ipragliflozin both inhibited renal and glomerular hypertrophy, and reduced NADPH oxidase 4 expression and subsequent oxidative stress...
