Project description:In a healthy person, the kidney filters nearly 200 g of glucose per day, almost all of which is reabsorbed. The primary transporter responsible for renal glucose reabsorption is sodium-glucose cotransporter-2 (SGLT2). Based on the impact of SGLT2 to prevent renal glucose wasting, SGLT2 inhibitors have been developed to treat diabetes and are the newest class of glucose-lowering agents approved in the United States. By inhibiting glucose reabsorption in the proximal tubule, these agents promote glycosuria, thereby reducing blood glucose concentrations and often resulting in modest weight loss. Recent work in humans and rodents has demonstrated that the clinical utility of these agents may not be limited to diabetes management: SGLT2 inhibitors have also shown therapeutic promise in improving outcomes in heart failure, atrial fibrillation, and, in preclinical studies, certain cancers. Unfortunately, these benefits are not without risk: SGLT2 inhibitors predispose to euglycemic ketoacidosis in those with type 2 diabetes and, largely for this reason, are not approved to treat type 1 diabetes. The mechanism for each of the beneficial and harmful effects of SGLT2 inhibitors-with the exception of their effect to lower plasma glucose concentrations-is an area of active investigation. In this review, we discuss the mechanisms by which these drugs cause euglycemic ketoacidosis and hyperglucagonemia and stimulate hepatic gluconeogenesis as well as their beneficial effects in cardiovascular disease and cancer. In so doing, we aim to highlight the crucial role for selecting patients for SGLT2 inhibitor therapy and highlight several crucial questions that remain unanswered.

Project description:As the first cardiovascular (CV) outcome trial of a glucose-lowering agent to demonstrate a reduction in the risk of CV events in patients with type 2 diabetes mellitus (T2DM), the EMPAgliflozin Removal of Excess Glucose: Cardiovascular OUTCOME Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME®) trial, which investigated the sodium glucose cotransporter 2 (SGLT2) inhibitor empagliflozin, has generated great interest among health care professionals. CV outcomes data for another SGLT2 inhibitor, canagliflozin, have been published recently in the CANagliflozin CardioVascular Assessment Study (CANVAS) Program, as have CV data from the retrospective real-world study Comparative Effectiveness of Cardiovascular Outcomes in New Users of Sodium-Glucose Cotransporter-2 Inhibitors (CVD-REAL), which compared SGLT2 inhibitors with other classes of glucose-lowering drugs. This review discusses the results of these three studies and, with a focus on EMPA-REG OUTCOME, examines the possible mechanisms by which SGLT2 inhibitors may reduce CV risk in patients with T2DM.

Project description:Acute myocardial infarction (AMI) is the leading cause of mortality worldwide. Dapagliflozin (DAPA), a sodium-glucose cotransporter-2 inhibitor (SGLT2i), is a new type of oral antidiabetic agent. Here, we examined the effects of DAPA on AMI and investigated the potential mechanisms.Heart tissue specimens were collected from C57BL/6J mice induced by ligation of the left anterior descending coronary artery and treated with DAPA at 1 mg/kg/day dose for 4 weeks after surgery. Echocardiography, histological staining, and RNA sequencing (RNA-seq) of these specimens were performed. The differentially expressed genes of interest were confirmed by qualitative RT-PCR (RT-qPCR) and western blotting (WB). In vitro experiments were performed to evaluate the effect of DAPA on myosin light-chain 4 (Myl4) upregulation and reduction of autophagy following hypoxic treatment. As a result, DAPA could improve cardiac function post MI by upregulating Myl4 and reducing autophagy; this finding suggests that the molecular regulation associated with Myl4 might be an important mechanism of AMI treatment by SGLT2i.

Project description:In addition to showing antidiabetic effects, sodium-glucose cotransporter 2 (SGLT2) inhibitors also reduce cardiovascular events in patients with type 2 diabetes mellitus. In major trials of cardiovascular outcomes, SGLT2 inhibitors have been shown to improve cardiovascular and renal outcomes, including reduced rehospitalization in patients with heart failure, regardless of the presence of diabetes. A recent report showed that the benefits of SGLT2 inhibitors in terms of cardiovascular deaths/admissions caused by heart failure and reduced ejection fraction were greater in Asians than in Whites. In this review, the first part demonstrates the results of recent clinical trials and their clinical implications and outlines current trials and upcoming research areas. The second part provides a general overview of the current understanding of the mechanisms of the cardiovascular benefits of SGLT2 inhibitors.

Project description:ObjectiveTo compare the risk of cardiovascular events between sodium glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors among people with type 2 diabetes in a real world context of clinical practice.DesignMulti-database retrospective cohort study using a prevalent new user design with subsequent meta-analysis.SettingCanadian Network for Observational Drug Effect Studies (CNODES), with administrative healthcare databases from seven Canadian provinces and the United Kingdom, 2013-18.Population209 867 new users of a SGLT2 inhibitor matched to 209 867 users of a DPP-4 inhibitor on time conditional propensity score and followed for a mean of 0.9 years.Main outcome measuresThe primary outcome was major adverse cardiovascular events (MACE, a composite of myocardial infarction, ischaemic stroke, or cardiovascular death). Secondary outcomes were the individual components of MACE, heart failure, and all cause mortality. Cox proportional hazards models were used to estimate site specific adjusted hazards ratios and 95% confidence intervals, comparing use of SGLT2 inhibitors with use of DPP-4 inhibitors in an as treated approach. Site specific results were pooled using random effects meta-analysis.ResultsCompared with DPP-4 inhibitors, SGLT2 inhibitors were associated with decreased risks of MACE (incidence rate per 1000 person years: 11.4 v 16.5; hazard ratio 0.76, 95% confidence interval 0.69 to 0.84), myocardial infarction (5.1 v 6.4; 0.82, 0.70 to 0.96), cardiovascular death (3.9 v 7.7; 0.60, 0.54 to 0.67), heart failure (3.1 v 7.7; 0.43, 0.37 to 0.51), and all cause mortality (8.7 v 17.3; 0.60, 0.54 to 0.67). SGLT2 inhibitors had more modest benefits for ischaemic stroke (2.6 v 3.5; 0.85, 0.72 to 1.01). Similar benefits for MACE were observed with canagliflozin (0.79, 0.66 to 0.94), dapagliflozin (0.73, 0.63 to 0.85), and empagliflozin (0.77, 0.68 to 0.87).ConclusionsIn this large observational study conducted in a real world clinical practice context, the short term use of SGLT2 inhibitors was associated with a decreased risk of cardiovascular events compared with the use of DPP-4 inhibitors.Trial registrationClinicalTrials.gov NCT03939624.

Project description:BackgroundThree large cardiovascular outcome trials have investigated the safety of sodium glucose cotransporter 2 (SGLT2) inhibitors.ObjectiveTo analyze the nationwide dispensing of SGLT2 inhibitors before and after the publication of these trials.MethodsA cross-sectional study was conducted of monthly prescription dispensing of SGLT2 inhibitors from May 23, 2014, to April 30, 2019, using nationwide data for Canada. An autoregressive integrated moving average (ARIMA) model was fitted to the monthly number of tablets dispensed for each SGLT2 inhibitor; the model included a ramp intervention function at the publication dates of interest to estimate the impact on SGLT2 inhibitor dispensing patterns.ResultsThe rate of canagliflozin and dapagliflozin dispensing declined after publication of results of the empagliflozin cardiovascular trial in September 2015. After publication of results of the canagliflozin trial in June 2017, which indicated a reduction in cardiovascular events and an increase in the risk of lower-limb amputation, canagliflozin remained the most commonly dispensed SGLT2 inhibitor, but its rate of dispensing declined further. In contrast, the rate of empagliflozin dispensing increased, while the rate of dapagliflozin dispensing was unchanged. After publication of the dapagliflozin trial in November 2018, which indicated no clear reduction in cardiovascular events, short-term trends in dispensing of canagliflozin, empagliflozin, and dapagliflozin were largely unaffected.ConclusionsThe cardiovascular outcome trials appeared to have an important impact on the dispensing of SGLT2 inhibitors in Canada.

Project description:SGLT2 inhibitors are glucose-lowering agents used to treat type 2 diabetes mellitus (T2DM). These agents target the kidney to promote urinary glucose excretion, resulting in improved blood glucose control. SGLT2-inhibitor therapy is also associated with weight loss and blood pressure (BP) lowering. Hypertension is a common comorbidity in patients with T2DM, and is associated with excess morbidity and mortality. This review summarizes data on the effect of SGLT2 inhibitors marketed in the US (namely canagliflozin, dapagliflozin, or empagliflozin) on BP in patients with T2DM. Boolean searches were conducted that included terms related to BP or hypertension with terms for SGLT2 inhibitors, canagliflozin, dapagliflozin, or empagliflozin using PubMed, Google, and Google Scholar. Data from numerous randomized controlled trials of SGLT2 inhibitors in patients with T2DM demonstrated clinically relevant reductions in both systolic and diastolic BP, assessed via seated office measurements and 24-hour ambulatory BP monitoring. Observed BP lowering was not associated with compensatory increases in heart rate. Circadian BP rhythm was also maintained. The mechanism of SGLT2 inhibitor-associated BP reduction is not fully understood, but is assumed to be related to osmotic diuresis and natriuresis. Other factors that may also contribute to BP reduction include SGLT2 inhibitor-associated decreases in body weight and reduced arterial stiffness. Local inhibition of the renin-angiotensin-aldosterone system secondary to increased delivery of sodium to the juxtaglomerular apparatus during SGLT2 inhibition has also been postulated. Although SGLT2 inhibitors are not indicated as BP-lowering agents, the modest decreases in systolic and diastolic BP observed with SGLT2 inhibitors may provide an extra clinical advantage for the majority of patients with T2DM, in addition to improving blood glucose control.
