AbstractSodium-glucose cotransporter 2 (SGLT2) inhibitors include a relatively new class of glucose-lowering drugs that reduce plasma glucose concentrations by inhibiting proximal tubular reabsorption of glucose in the kidney, while increasing its excretion in urine. Recent large randomised controlled trials have demonstrated that many of these agents reduce the occurrence of major adverse cardiovascular events, hospitalisation for heart failure, cardiovascular death and/or chronic kidney disease progression in patients with and without type 2 diabetes mellitus (DM2). Given their unique insulin-independent mode of action and favourable efficacy and adverse-event profile, SGLT2 inhibitors are promising and they offer an interesting therapeutic approach for the cardiologist to incorporate into routine practice. However, despite accumulating data supporting this class of therapy, cardiologists infrequently prescribe SGLT2 inhibitors, potentially due to a lack of familiarity with their use and the reticence to change DM medication. Here, we provide an up-to-date practical guide highlighting important elements of treatment initiation based on real-world evidence and expert opinion. We describe how to change DM medication, including insulin dosing when appropriate, and how to anticipate any adverse events based on real-world experience in patients with DM2 in the Meander Medical Centre in Amersfoort, the Netherlands. This includes a simple algorithm showing how to initiate SGLT2 inhibitor treatment safely, while considering the consequence of the glucosuric effects of these inhibitors for the individual patient.

Abstract Objective To 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. Design Multi-database retrospective cohort study using a prevalent new user design with subsequent meta-analysis. Setting Canadian Network for Observational Drug Effect Studies (CNODES), with administrative healthcare databases from seven Canadian provinces and the United Kingdom, 2013-18. Population 209 867 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 measures The 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. Results Compared 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). Conclusions In 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.

Abstract BackgroundHeart failure (HF) has become a healthcare challenge worldwide. Recently, certain trials on sodium-glucose co-transporter-2 (SGLT2) inhibitor showed benefits for patients with HF. This study aimed to systematically review the literature and investigate the clinical efficacy of SGLT2 inhibitors in cardiovascular events among patients with and without HF. Methods We searched randomized controlled trials (RCTs) in PubMed, Cochrane databases, Embase, and ClinicalTrials.gov registry form inception to October 2020. Dichotomous variables were pooled using a random-effects model and presented with a risk ratio (RR) and 95% confidence interval (CI). Subgroup meta-analyses were carried out by high/low SGLT2/SGLT1 selectivity and individual SGLT2 inhibitor.ResultsA total of 10 RCTs comprised of 52,607 patients were eligible for the analyses. SGLT2 inhibitors reduced the risk of total cardiovascular death or hospitalization for HF (RR 0.79, [95% CI: 0.74 to 0.84]; p < 0.01, I2 = 31%). Apart from stroke, SGLT2 inhibitors contributed to a risk reduction in major adverse cardiovascular events (MACE, RR 0.93, [95% CI: 0.88 to 0.99]; p = 0.03, I2 = 0), all-cause mortality (RR 0.92, [95% CI: 0.85 to 0.99]; p = 0.03, I2 = 0), cardiovascular death (RR 0.91, [95% CI: 0.83 to 0.99]; p = 0.03, I2 = 0), hospitalization for HF (RR 0.72, [95% CI: 0.66 to 0.79]; p < 0.01, I2 = 0), and myocardial infarction (RR 0.89, [95% CI: 0.80 to 0.99]; p = 0.03, I2 = 0). For HF patients, SGLT2 inhibitors had more clinical benefits in terms of all-cause mortality and cardiovascular death, while advantages were observed in MACE and myocardial infarction for non-HF patients. Furthermore, SGLT2 inhibitors with low SGLT2/SGLT1 selectivity have better efficacy for hospitalization of HF, compared with high-selectivity inhibitors (RR 0.51 [95% CI: 0.35-0.75] versus 0.73 [95% CI: 0.66-0.81] for HF patients). ConclusionsSGLT2 inhibitors significantly mitigate hospitalization for HF. Between HF and non-HF populations, this regimen reduce mortality for HF patients and improve MACE and myocardial infarction for non-HF patients. The SGLT2 inhibitor, mixed with the effect of SGLT1 inhibitors, may lead to a lower risk of hospitalization for HF.

ObjectiveTo investigate the change of chronic diabetic macular oedema (DMO) in vitrectomised eyes when the administration of sodium–glucose cotransporter 2 (SGLT2) inhibitors is initiated as a systemic medical treatment.Methods and analysisThis study involved 10 eyes of five patients with chronic DMO lasting more than 6 months who had previously undergone vitrectomy and whose systemic medical treatments were newly changed to SGLT2 inhibitors. In this study, chronic DMO was defined as persistent diffuse macular oedema despite ophthalmic treatment in patients with diabetes. Patients who received antivascular endothelial growth factor therapy or steroids administration, or change of eye-drop medication from at 3 months before and after the initiation of SGLT2 inhibitors, were excluded. In this study, visual acuity (VA) and central retinal thickness (CRT, μm) prior to and at 3, 6 and 12 months after the initiation of SGLT2 inhibitors were retrospectively compared. The Wilcoxon signed-rank test was used for statistical analysis.ResultsIn the 10 treated eyes, from at baseline to at 3, 6 and 12 months after the initiation of SGLT2 inhibitor, median VA (logMAR) improved from 0.35 to 0.15 (p=0.038), 0.2 (p=0.157) and 0.2 (p=0.096), respectively, and median CRT significantly reduced from 500.5 µm to 410 µm (p<0.01), 378 µm (p<0.01) and 339 µm (p<0.01), respectively.ConclusionAlthough this study involved only five patients, our findings indicate that SGLT2 inhibitors might have structural efficacy for chronic DMO in vitrectomised eyes.

Abstract Background We compared the effects of sodium–glucose cotransporter 2 (SGLT2) inhibitors on renal function in participants with type 2 diabetes and chronic kidney disease (CKD) classified by degree of albuminuria. Methods A retrospective review of the clinical records of Japanese participants with type 2 diabetes (age > 20 years; SGLT2 inhibitor treatment > 2 years; estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2) was conducted. Based on the urinary albumin-to-creatinine ratio (UACR) or urinary protein-to-creatinine ratio (UPCR) at the start of SGLT2 inhibitor administration, participants were categorized into three groups: normoalbuminuria (A1; UACR < 30 mg/g Cr or UPCR < 0.15 g/g Cr), microalbuminuria (A2; UACR 30 to < 300 mg/g Cr or UPCR 0.15 to < 0.50 g/g Cr), and macroalbuminuria (A3; UACR ≥ 300 mg/g Cr or UPCR ≥ 0.50 g/g Cr). The study outcome was a comparison of the rates of change in renal function evaluated by eGFR at 2 years after starting SGLT2 inhibitor among the three groups. Results A total of 87 participants (40 females, 47 males) were categorized into three groups: A1 (n = 46), A2 (n = 25), and A3 (n = 16). eGFR was similarly decreased at 2 years before starting SGLT2 inhibitor in all three groups. However, the decline in eGFR was ameliorated at 2 years after starting SGLT2 inhibitor, and eGFR was rather increased in the A1 and A2 groups. Interestingly, the rate of change in eGFR at 2 years after starting SGLT2 inhibitor in the A1 group was significantly higher than that in the A3 group. Conclusions These results demonstrate that more favorable effects of SGLT2 inhibitors on renal function were observed in participants with type 2 diabetes and CKD with normoalbuminuria compared with those with macroalbuminuria.

AbstractSodium–glucose cotransporter 2 (SGLT2) inhibitors are increasingly prescribed for the treatment of patients with type 2 diabetes to reduce the risk of cardiovascular events, including heart failure (HF). The mechanisms by which SGLT2 inhibitors reduce such risk are likely to be independent of diabetes status and improvement of glycemic control. In this commentary, based on recent mediation analyses of cardiovascular outcome trials with SGLT2 inhibitors, we discuss the prognostic role of a well-known HF-related biomarker, amino-terminal pro-B-type natriuretic peptide (NT-proBNP), in patients receiving SGLT2 inhibitors. Interestingly, the NT-proBNP concentration had a relatively small impact on the SGLT2 inhibitor-associated benefit on HF events, suggesting a limited value in measuring NT-proBNP concentrations to monitor effects on cardiovascular outcomes after initiation of SGLT2 inhibitor therapy. Instead, clinical factors, such as body weight and volume status, were prognostic for cardiovascular outcomes. As shown in some biomarker studies, short-term SGLT2 inhibitor treatment significantly improved volume and HF-related health status, despite the absence of a significant change in NT-proBNP concentration. Given the early and continuous risk reduction in HF events seen in the cardiovascular outcome trials with SGLT2 inhibitors, changes in these fundamental clinical parameters after initiation of SGLT2 inhibitor therapy, independent of NT-proBNP, could be more prognostic and could represent key determinants to identify responders or non-responders to SGLT2 inhibitors for cardiovascular outcomes. Thus, this commentary highlights the clinical importance of establishing how clinicians should monitor patients initiating SGLT2 inhibitor therapy to predict the expected cardiovascular benefit. Further detailed investigations and discussion to better understand this ‘‘black box’’ are urgently warranted.

Abstract Background Sodium glucose cotransporter 2 (SGLT2) inhibitors are antidiabetic drugs that control plasma glucose levels by inhibiting reabsorption of glucose in kidney. Recent clinical trials have suggested a class effect of SGLT2 inhibitors in preventing hospitalization due to heart failure. However, the underlying mechanism has not been fully elucidated. Purpose We investigated the direct effect of the SGLT2 inhibitor, Canagliflozin (Cana), on myocardial redox state in humans. Methods The study included 48 patients undergoing cardiac surgery. Fresh myocardial tissues were incubated ex vivo with or without Cana and then used for superoxide quantification and Western immunoblotting. NADPH-oxidases activity was evaluated with NADPH 100μM stimulation, while nitric oxide synthase (NOS) coupling was assessed by using N(ω)-nitro-L-arginine methyl ester (L-NAME, a NOS inhibitor). A human cardiomyocyte (HCM) cell line was also used for in vitro validation of the effects of Cana on myocardium. Results Ex vivo incubation of myocardium with Cana significantly reduced baseline (A) and NADPH-oxidase-derived O2·− (B) and improved NOS coupling reflected by positive L-NAME delta O2·− values (C). Regulation of NADPH-oxidases activity by Cana was found to result from reduced GTP-activation (D) and consequent membrane translocation (E) of Rac1, a key subunit of NADPH-oxidases. Cana also reduced tetrahydrobiopterin (BH4) oxidation, increasing its bioavailability (F), which is a key mechanism to improve NOS coupling. Incubation with Cana enhanced phosphorylation of AMPK, and the downstream signalling, ACC (not shown). Additional Compound C, which is inhibitor of AMPK, significantly reversed these effects of Cana (A, B, C, D, E, F). These findings were replicated in HCM (not shown). In line with these, Cana increased the ADP/ATP ratio of cytoplasm in HCM, which could provide an upstream mechanism for AMPK activation. Conclusions We demonstrate for the first time in humans, that Cana suppresses myocardial NADPH-oxidases activity and improves NOS coupling through an AMPK-mediated pathway. This could be an underlying mechanism for the cardioprotective effects of SGLT2 inhibitors.

BackgroundThe association between early changes in albuminuria and kidney and cardiovascular events is primarily based on trials of renin-angiotensin system blockade. It is unclear whether this association occurs with sodium-glucose cotransporter 2 inhibition.MethodsThe Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial enrolled 4401 patients with type 2 diabetes and CKD (urinary albumin-creatinine ratio [UACR] >300 mg/g). This post hoc analysis assessed canagliflozin’s effect on albuminuria and how early change in albuminuria (baseline to week 26) is associated with the primary kidney outcome (ESKD, doubling of serum creatinine, or kidney death), major adverse cardiovascular events, and hospitalization for heart failure or cardiovascular death.ResultsComplete data for early change in albuminuria and other covariates were available for 3836 (87.2%) participants in the CREDENCE trial. Compared with placebo, canagliflozin lowered UACR by 31% (95% confidence interval [95% CI], 27% to 36%) at week 26, and significantly increased the likelihood of achieving a 30% reduction in UACR (odds ratio, 2.69; 95% CI, 2.35 to 3.07). Each 30% decrease in UACR over the first 26 weeks was independently associated with a lower hazard for the primary kidney outcome (hazard ratio [HR], 0.71; 95% CI, 0.67 to 0.76; P<0.001), major adverse cardiovascular events (HR, 0.92; 95% CI, 0.88 to 0.96; P<0.001), and hospitalization for heart failure or cardiovascular death (HR, 0.86; 95% CI, 0.81 to 0.90; P<0.001). Residual albuminuria levels at week 26 remained a strong independent risk factor for kidney and cardiovascular events, overall and in each treatment arm.ConclusionsIn people with type 2 diabetes and CKD, use of canagliflozin results in early, sustained reductions in albuminuria, which were independently associated with long-term kidney and cardiovascular outcomes.

Selective sodium–glucose cotransporter 2 (SGLT2) inhibitors reduced the risk of hospitalization for heart failure in patients with or without type 2 diabetes (T2DM) in large-scale clinical trials. The exact mechanism of action is currently unclear. The dual SGLT1/2 inhibitor sotagliflozin not only reduced hospitalization for HF in patients with T2DM, but also lowered the risk of myocardial infarction and stroke, suggesting a possible additional benefit related to SGLT1 inhibition. In fact, several preclinical studies suggest that SGLT1 plays an important role in cardiac pathophysiological processes. In this review, our aim is to establish the clinical significance of myocardial SGLT1 inhibition through reviewing basic research studies in the context of SGLT2 inhibitor trials.

IntroductionSodium-glucose cotransporter 2 (SGLT2) inhibitors are a new class of antihyperglycaemic agents that promote urinary glucose excretion in the renal proximal tubule and have cardio-protective and renal-protective properties. However, there are several safety concerns related to increased risks of hypoglycaemic, urinary tract infections and ketoacidosis. Ketoacidosis is a potentially fatal complication that often presents as euglycaemic ketoacidosis during SGLT2 inhibitor treatment. Furthermore, invasive treatment and related surgical stress may increase the risk of ketogenesis. Therefore, this study aims to clarify the incidence of SGLT2 inhibitor-associated postoperative ketoacidosis (SAPKA) among patients who are receiving SGLT2 inhibitors and undergoing surgery under general anaesthesia.Methods and analysisThis multicentre, prospective, observational study will recruit 750 adult Japanese patients with diabetes who are receiving SGLT2 inhibitors and undergoing surgery under general anaesthesia. Urine samples will be collected on postoperative days 0, 1, 2 and 3. Blood gas analysis will be performed when urine ketone positivity is detected. The incidence of postoperative ketoacidosis will be identified based on urine ketone positivity and a blood pH of ≤7.3. The study will also collect data to identify risk factors for SAPKA.Ethics and disseminationThe study protocol has been approved by the ethics committee of Kyorin University (approval number: 785, 26 October 2020) and local ethical approval will be required at each participating centre. Study findings will be submitted to peer-reviewed journals and abstracts will be submitted to relevant national and international meetings.Trial registration numberUMIN000042795

Background: Heart failure with preserved ejection fraction (HFpEF) is a complex disease which accounts for more than half of all HF hospital admissions with high prevalence and lack of effective evidence-based management. Sodium-glucose cotransporter 2 (SGLT2) inhibitor is a new antidiabetic drug that recently gained a new role in the management of heart failure with reduced ejection fraction but its role in HFpEF had yet to be studied.Study and results: EMPEROR-Preserved trial set out to evaluate the effects of SGLT2 inhibition with empagliflozin on major heart failure outcomes in patients with HFpEF. The patients were randomized in a 1:1 fashion into two groups; to receive either empagliflozin 10 mg per day (n = 2,997) or placebo (n = 2,991) in addition to usual therapy. Empagliflozin led to a 21% risk reduction of the composite of cardiovascular death or hospitalization for heart failure, which was mainly related to a 29% lower risk of hospitalization for heart failure rather than effect on cardiovascular death empagliflozin. The effects SGLT2 inhibitors were consistent in all patients.
