International audience; Aims: In the EMPA-REG OUTCOME trial, empagliflozin reduced risk of death from heart failure (HF) or hospitalization for heart failure (HHF) versus placebo in patients with type 2 diabetes mellitus (T2DM) and established cardiovascular (CV) disease. We evaluated post hoc the degree to which covariates mediated the effects of empagliflozin on HHF or HF death.Methods and results: A mediator had to fulfil the following criteria: (i) affected by active treatment, (ii) associated with the outcome, and finally (iii) adjustment for it results in a reduced treatment effect compared with unadjusted analysis. Potential mediators were calculated as change from baseline or updated mean and evaluated in univariable analyses as time-dependent covariates in Cox regression of time to HHF or HF death; those with the largest mediating effects were then included in a multivariable analysis. Increases in heart rate, log urine albumin-to-creatinine ratio (UACR), waist circumference, and uric acid were associated with increased risk of HHF or HF death; increases in high-density lipoprotein cholesterol, estimated glomerular filtration rate, haematocrit, haemoglobin, and albumin were associated with reduced risk of HHF or HF death. In univariable analyses, change from baseline in haematocrit, haemoglobin, albumin, uric acid, and logUACR mediated 51%, 54%, 23%, 24%, and 27% of the risk reduction with empagliflozin versus placebo, respectively. Multivariable analysis including haemoglobin, logUACR, and uric acid mediated 85% of risk reduction with similar results when updated means were evaluated.Conclusions: Changes in haematocrit and haemoglobin were the most important mediators of the reduction in HHF and death from HF in patients with T2DM and established CV disease treated with empagliflozin. Albumin, uric acid, and logUACR had smaller mediating effects in this population.

OBJECTIVE To determine the association of adipose tissue insulin resistance with longitudinal changes in biomarkers of adipose tissue function, circulating lipids, and dysglycemia. RESEARCH DESIGN AND METHODS Adults at risk for type 2 diabetes in the Prospective Metabolism and Islet Cell Evaluation (PROMISE) cohort had up to four assessments over 9 years (n = 468). Adipose tissue insulin resistance was determined using a novel validated index, Adipo-IR, calculated as the product of fasting insulin and nonesterified fatty acids measured at baseline. Fasting serum was used to measure biomarkers of adipose tissue function (adiponectin and soluble CD163 [sCD163]), circulating lipids (total cholesterol, HDL, LDL, triglyceride [TG]), and systemic inflammation (interleukin-6 [IL-6] and tumor necrosis factor-α [TNF-α]). Incident dysglycemia was defined as the onset of impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes at follow-up. Generalized estimating equation (GEE) models were used to assess the relationship of Adipo-IR with longitudinal outcomes. RESULTS GEE analyses showed that elevated Adipo-IR was longitudinally associated with adipose tissue dysfunction (adiponectin −4.20% [95% CI −6.40 to −1.95]; sCD163 4.36% [1.73–7.06], HDL −3.87% [−5.15 to −2.57], TG 9.26% [5.01–13.69]). Adipo-IR was associated with increased risk of incident dysglycemia (odds ratio 1.59 [95% CI 1.09–2.31] per SD increase). Associations remained significant after adjustment for waist circumference and surrogate indices for insulin resistance. There were no significant longitudinal associations of Adipo-IR with IL-6, TNF-α, total cholesterol, or LDL. CONCLUSIONS Our findings demonstrate that adipose tissue insulin resistance is prospectively associated with adipose tissue function, HDL, TG, and incident dysglycemia.

Heart failure is prevalent in those with type 2 diabetes and chronic kidney disease, and is associated with significant mortality and morbidity. In the CREDENCE trial, canagliflozin reduced the risk of hospitalization for heart failure (HHF) or cardiovascular (CV) death by 31%. In the current analysis we sought to determine whether the effect of canagliflozin on HHF/CV death differed in subgroups defined by key baseline participant characteristics. Cox regression models were used to estimate hazard ratios and 95% confidence intervals. Canagliflozin was associated with a reduction in the relative risk of HHF/CV death regardless of age, sex, history of heart failure or CV disease, and the use of loop diuretics or glucagon-like peptide-1 receptor agonists (all p(interaction) > .114). The absolute benefit of canagliflozin was greater in those at highest baseline risk, such as those with CV disease (50 fewer events/1000 patients treated over 2.5 years vs. 20 fewer events in those without CV disease) or advanced kidney disease (estimated glomerular filtration rate [eGFR] 30-45 mL/min/1.73m(2): 61 events prevented/1000 patients treated over 2.5 years vs. 23 events in eGFR 60-90 mL/min/1.73m(2)). Canagliflozin consistently reduces the proportional risk of HHF/CV death across a broad range of subgroups with greater absolute benefits in those at highest baseline risk.

The discovery of insulin in 1921 and the progress achieved in the ensuing century highlight the promise and challenge of biochemically modifying the molecule to achieve optimization of its delivery and therapeutic efficacy. Normal endogenous insulin secretion consists of a highly orchestrated physiologic loop wherein multiple metabolic signals trigger the pancreatic β cells to secrete the precise amount of insulin into the portal system required to maintain euglycemia. Accordingly, in the treatment of diabetes, attempting to replicate this complex physiology with exogenous insulin therapy given subcutaneously presents a clinical challenge. In this context, recombinant DNA-based technology has enabled the development of insulin analogs that have been specifically designed to confer advantageous pharmacodynamic features that can better mimic endogenous insulin secretion. In this review, we discuss the development of the most widely available insulin preparations and provide evidence-based insight into their use in clinical practice.

Aim To determine the relationship between polyvascular disease and risk of hospitalization for heart failure (HHF) and cardiovascular (CV) death in the EMPA‐REG OUTCOME population, and the relationship of kidney dysfunction co‐existent with polyvascular disease on CV/heart failure (HF) outcomes. Materials and Methods Patients with type 2 diabetes and atherosclerotic CV (ASCVD) received empagliflozin 10, 25 mg or placebo. Post hoc, subgroups were analyzed by one versus two or more vascular beds, and the estimated glomerular filtration rate ([eGFR] < vs. ≥60 mL/min/1.73 m2) at baseline. The empagliflozin arms were pooled. Time to CV death, HHF, CV death (excluding fatal stroke) or HHF, all‐cause mortality (ACM) and 3‐point major adverse CV events (3P‐MACE) were assessed using multivariable Cox regression models. Results Baseline characteristics (N = 6959) within subgroups were balanced between treatment groups. In the placebo group, two or more versus one vascular bed increased HHF risk (1.59 [95% confidence interval 1.02, 2.49]), CV death (2.17 [1.52, 3.09]), CV death/HHF (1.79 [1.32, 2.43]), ACM (1.95 [1.44, 2.64]) and 3P‐MACE (1.76 [1.36, 2.27]). Hazard ratios for those with polyvascular disease/kidney dysfunction (vs. 1 vascular bed/eGFR ≥60 mL/min/1.73 m2) were HHF 2.80 (1.46, 5.36), CV death 3.10 (1.87, 5.13), CV death/HHF 2.71 (1.74, 4.23), ACM 2.59 (1.67, 4.02) and 3P‐MACE 2.62 (1.82, 3.77). Empagliflozin reduced the risk of all outcomes across subgroups. Conclusions Polyvascular disease with/without kidney dysfunction markedly increases the risk of HF/CV events. Empagliflozin consistently reduces risk, regardless of vascular bed and kidney function status.

Aims/hypothesis Type 2 diabetes, particularly with concomitant CVD, is associated with an increased risk of cognitive impairment. We assessed the effect on accelerated cognitive decline (ACD) of the DPP-4 inhibitor linagliptin vs the sulfonylurea glimepiride in individuals with type 2 diabetes. Methods The CAROLINA-COGNITION study was part of the randomised, double-blind, active-controlled CAROLINA trial that evaluated the cardiovascular safety of linagliptin vs glimepiride in individuals with age ≥40 and ≤85 years and HbA1c 48–69 mmol/mol (6.5–8.5%) receiving standard care, excluding insulin therapy. Participants were randomised 1:1 using an interactive telephone- and web-based system and treatment assignment was determined by a computer-generated random sequence with stratification by center. The primary cognitive outcome was occurrence of ACD at end of follow-up, defined as a regression-based index score ≤16th percentile on either the Mini-Mental State Examination (MMSE) or a composite measure of attention and executive functioning, in participants with a baseline MMSE score ≥24. Prespecified additional analyses included effects on ACD at week 160, in subgroups (sex, age, race, ethnicity, depressive symptoms, cardiovascular risk, duration of type 2 diabetes, albuminuria), and absolute changes in cognitive performance. Participants, caregivers, and people involved in measurements, examinations or adjudication, were all masked to treatment assignment. Results Of 6033 participants recruited from hospital and primary care sites, 3163 (38.0% female, mean age/diabetes duration 64/7.6 years, MMSE score 28.5, HbA1c 54 mmol/mol [7.1%]) represent the CAROLINA-COGNITION cohort. Over median 6.1 years, ACD occurred in 27.8% (449/1618, linagliptin) vs 27.6% (426/1545, glimepiride), OR 1.01 (95% CI 0.86, 1.18). Also, no differences in ACD were observed at week 160 (OR 1.07 [0.91, 1.25]), between treatments across subgroups, or for absolute cognitive changes. Conclusions/interpretation In a large, international outcome trial in people with relatively early type 2 diabetes at elevated cardiovascular risk, no difference in risk for ACD was observed between linagliptin and glimepiride over 6.1 years.

There has been a great deal of controversy regarding priority of discovery of insulin. Indeed, many scientists made important and, in some cases, seminal contributions to identifying the endocrine role of the pancreas and the potential for pancreatic extracts to have a glucose-lowering effect. The purpose of this article is to describe the early experiences with respect to research leading to the discovery of insulin in Toronto (ON, Canada). The experiments conducted at the University of Toronto resulted in the first demonstration that a pancreatic extract could be prepared that would consistently lower glucose, reverse ketosis and arrest the catabolic effects of type 1 diabetes. The remarkably rapid commercial production of insulin soon followed. The Toronto story begins on 17 May 1921, when Frederick Banting and Charles Best began their summer research project in the laboratory of John James Rickard Macleod, and we are now celebrating the 100th anniversary of this landmark achievement. The article herein outlines the steps leading up to the discovery of insulin and provides an overview of some of the key developments in insulin therapy over the past 100 years.

Background Nephrotic-range proteinuria (NRP) is associated with rapid kidney function loss and increased cardiovascular (CV) disease risk. We assessed the effects of linagliptin (LINA) on CV and kidney outcomes in people with Type 2 diabetes (T2D) with or without NRP. Methods Cardiovascular and renal microvascular outcome study with LINA randomized participants with T2D and CV disease and/or kidney disease to LINA 5 mg or placebo (PBO). The primary endpoint [time to first occurrence of 3-point major adverse cardiac events (3P-MACE)], and kidney outcomes, were evaluated by NRP status [urinary albumin:creatinine ratio (UACR) ≥2200 mg/g] at baseline (BL) in participants treated with one or more dose of study medication. Results NRP was present in 646/6979 [9.3% (LINA/PBO n = 317/n = 329); median UACR 3486 (Q1: 2746/Q3: 4941) mg/g] participants, who compared with no-NRP were younger (62.3/66.1 years) and had lower estimated glomerular filtration rate (eGFR) (39.9/56.1 mL/min/1.73 m2). Over a median of 2.2 years, 3P-MACE occurred with a 2.0-fold higher rate in NRP versus no-NRP (PBO group), with a neutral LINA effect, regardless of NRP. The composite of time to renal death, end-stage kidney disease (ESKD) or decrease of ≥40 or ≥50% in eGFR, occurred with 12.3- and 13.6-fold higher rate with NRP (PBO group); evidence of heterogeneity of effects with LINA was observed for the former [NRP yes/no: hazard ratio 0.80 (0.63–1.01)/1.25 (1.02–1.54); P-interaction 0.005], but not the latter [0.83 (0.64–1.09)/1.17 (0.91–1.51), P-interaction 0.07]. No heterogeneity was observed for renal death or ESKD [0.88 (0.64–1.21)/0.94 (0.67–1.31), P-interaction 0.79]. Glycated haemoglobin A1c (HbA1c) was significantly reduced regardless of NRP, without increasing hypoglycaemia risk. Regression to normoalbuminuria [1.20 (1.07–1.34)] and reduction of UACR ≥50% [1.15 (1.07–1.25)] from BL, occurred more frequently with LINA, regardless of NRP status (P-interactions >0.05). Conclusions Individuals with T2D and NRP have a high disease burden. LINA reduces their albuminuria burden and HbA1c, without affecting CV or kidney risk., Graphical Abstract

Patients with type 2 diabetes and atherosclerotic cardiovascular disease are at high clinical risk. We assessed the effect of the sodium-glucose co-transporter-2 inhibitor, empagliflozin, on total cardiovascular events and admissions to hospital in the EMPA-REG OUTCOME trial.The EMPA-REG OUTCOME trial was a randomised, double-blind, non-inferiority trial of patients (aged ≥18 years) with type 2 diabetes and atherosclerotic cardiovascular disease done between August, 2010, and April, 2015. Participants were randomly assigned (1:1:1) to empagliflozin 10 mg or 25 mg, or placebo. The primary outcome was major adverse cardiovascular events: a composite of cardiovascular death, non-fatal stroke, or non-fatal myocardial infarction. As prespecified, the effects of pooled empagliflozin versus placebo were assessed on total (first plus recurrent) events of major adverse cardiovascular events, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, and admission to hospital for heart failure. We also did post-hoc analyses on additional cardiovascular and admission to hospital outcomes. We used statistical models that preserve randomisation and account for correlation of recurrent events, including negative binomial regression, as prespecified for the primary analyses. The EMPA-REG OUTCOME trial is registered with ClinicalTrials.gov, NCT01131676, and is closed to accrual.In the EMPA-REG OUTCOME trial, 7020 patients were randomly assigned and treated with empagliflozin 10 mg (n=2345), empagliflozin 25 mg (n=2342), or placebo (n=2333) and followed up for a median of 3·2 years (IQR 2·2 to 3·6) in the pooled empagliflozin group and 3·1 years (2·2 to 3·5) in the placebo group. Analysing total (first plus recurrent) events, empagliflozin versus placebo reduced the risk of major adverse cardiovascular events (rate ratio [RR] 0·78 [95% CI 0·67 to 0·91]; p=0·0020; 12·88 [95% CI 3·74 to 22·02] events prevented per 1000 patient-years); fatal or non-fatal myocardial infarction (0·79 [0·62 to 0·998]; p=0·049; 4·97 [-0·68 to 10·61] events prevented per 1000 patient-years); the composite of fatal or non-fatal myocardial infarction, or coronary revascularisation (0·80 [0·67 to 0·95]; p=0·012; 11·65 [1·25 to 22·05] events prevented per 1000 patient-years); admission to hospital for heart failure (0·58 [0·42 to 0·81]; p=0·0012; 9·67 [3·07 to 16·28] events prevented per 1000 patient-years); and all-cause admission to hospital (0·83 [0·76 to 0·91]; p0·0001; 50·41 [26·20 to 74·63] events prevented per 1000 patient-years). For outcomes significantly reduced with empagliflozin, risk reductions were numerically larger for total events than for first events. Total fatal or non-fatal stroke was not significantly different between treatment groups (RR 1·10 [95% CI 0·82 to 1·49]; p=0·52).Empagliflozin reduced the total burden of cardiovascular complications and all-cause admission to hospital in patients with type 2 diabetes and atherosclerotic cardiovascular disease.The Boehringer Ingelheim and Lilly Alliance.

BACKGROUND AND OBJECTIVES: The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial demonstrated that the sodium glucose cotransporter 2 (SGLT2) inhibitor canagliflozin reduced the risk of kidney failure and cardiovascular events in participants with type 2 diabetes mellitus and CKD. Little is known about the use of SGLT2 inhibitors in patients with eGFR 300–5000 mg/g, and an eGFR of 30 to 0.20). The estimate for kidney failure in participants with eGFR 0.12). CONCLUSIONS: This post hoc analysis suggests canagliflozin slowed progression of kidney disease, without increasing AKI, even in participants with eGFR

BackgroundPatients with type 2 diabetes (T2D) and metabolic syndrome (MetS) are at greater cardiovascular risk than those with T2D without MetS. In the current report we aim to study the characteristics, cardio-renal outcomes and the effect of empagliflozin in patients with MetS enrolled in the EMPA-REG OUTCOME trial.MethodsA total of 7020 patients with T2D and atherosclerotic cardiovascular disease were treated with empagliflozin (10 mg or 25 mg) or placebo for a median of 3.1 years. The World Health Organization MetS criteria could be determined for 6985 (99.5%) patients. We assessed the association between baseline MetS and multiple cardio-renal endpoints using Cox regression models, and we studied the change in the individual component over time of the MetS using mixed effect models.ResultsMetS at baseline was present in 5740 (82%) patients; these were more often white and had more often albuminuria and heart failure, had lower eGFR and HDL-cholesterol, and higher blood pressure, body mass index, waist circumference, and triglycerides. In the placebo group, patients with MetS had a higher risk of all outcomes including cardiovascular death: HR = 1.73 (95% CI 1.01–2.98), heart failure hospitalization: HR = 2.64 (95% CI 1.22, 5.72), and new or worsening nephropathy: HR = 3.11 (95% CI 2.17–4.46). The beneficial effect of empagliflozin was consistent on all cardio-renal outcomes regardless of presence of MetS.ConclusionsA large proportion of the EMPA-REG OUTCOME population fulfills the criteria for MetS. Those with MetS had increased risk of adverse cardio-renal outcomes. Compared with placebo, empagliflozin improved cardio-renal outcomes in patients with and without MetS.Trial registrationClinical Trial Registration: URL:https://www.clinicaltrials.gov.

Aims:\ud The EMPA‐REG OUTCOME trial demonstrated reductions in cardiovascular (CV) death and heart failure (HF) outcomes with empagliflozin, a sodium–glucose co‐transporter 2 inhibitor, in patients with type 2 diabetes and established CV disease over a study period of 3 years. We aimed to investigate the early benefit–risk profile of empagliflozin in patients enrolled in the EMPA‐REG OUTCOME trial according to HF status at baseline.\ud \ud Methods and results:\ud The effects of treatments on glycated haemoglobin, systolic blood pressure and body weight, and on the HF endpoints of hospitalization for HF (HHF), HHF or CV death, and HHF or all‐cause mortality were evaluated at 12 weeks, 6 months, and 1 year after randomization. Occurrence of adverse events (AEs) during these time points was also evaluated. Compared with placebo, empagliflozin lowered glycated haemoglobin, systolic blood pressure, and body weight and rates of all the HF endpoints, as early as at 12 weeks, regardless of HF status at baseline. Favourable clinical and metabolic effects were maintained over time. AEs were generally higher in those with HF than without HF; however, compared with placebo, empagliflozin did not increase risk of developing AEs over the first year of treatment.\ud \ud Conclusions:\ud In the EMPA‐REG OUTCOME trial, the use of empagliflozin led to early and beneficial effects on clinical, metabolic, and HF outcomes in patients with type 2 diabetes with or without HF at baseline, which were already apparent within 12 weeks from initiation of treatment. Over the first year of treatment, no safety concern was detected with the use of empagliflozin.

Associations between body mass index (BMI) and the cardiovascular (CV) and kidney efficacy of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in patients with type 2 diabetes (T2D) are uncertain; therefore, data analysed separately from the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial and the Trial to Evaluate Cardiovascular and Other Long-term Outcomes with Semaglutide in Subjects with Type 2 Diabetes (SUSTAIN 6) were examined. These international, randomized, placebo-controlled trials investigated liraglutide and semaglutide (both subcutaneous) in patients with T2D and at high risk of CV events. In post hoc analyses, patients were categorized by baseline BMI (

The randomized, double‐blind, cardiovascular outcomes trials LEADER (NCT01179048) and SUSTAIN 6 (NCT01720446) showed cardiovascular risk reduction in patients with type 2 diabetes treated with liraglutide and semaglutide, respectively, compared with placebo. This post hoc analysis examined the impact of microvascular disease at baseline on cardiovascular outcomes in these trials, and the efficacy of liraglutide (1.8 mg) and once‐weekly semaglutide (0.5‐1.0 mg) in patients with and without microvascular disease. In total, 9340 patients from LEADER and 3297 patients from SUSTAIN 6 were included in this analysis; of these, 5761 and 2356 had a history of microvascular disease at baseline and 3835 and 1640 had a history of both microvascular and macrovascular disease, respectively. Patients with microvascular disease were shown to have an increased risk of major adverse cardiovascular events compared with patients without microvascular disease (hazard ratio [95% confidence interval] in LEADER: 1.15 [1.03; 1.29], P = .0136; SUSTAIN 6: 1.56 [1.14; 2.17], P = .0064). Liraglutide and semaglutide consistently reduced cardiovascular risk in patients with and without microvascular disease.

Context Control of multiple cardiovascular (CV) risk factors reduces CV events in individuals with type 2 diabetes. Objective To investigate this association in a contemporary clinical trial population, including how CV risk factor control affects the CV benefits of empagliflozin, a sodium-glucose cotransporter-2 inhibitor. Design Post hoc analysis. Setting Randomized CV outcome trial (EMPA-REG OUTCOME). Participants Type 2 diabetes patients with established CV disease. Intervention Empagliflozin or placebo. Main Outcome Measures Risk of CV outcomes—including the treatment effect of empagliflozin—by achieving 7 goals for CV risk factor control at baseline: (1) glycated hemoglobin Results In the placebo group, the hazard ratio (HR) for CV death was 4.00 (95% CI, 2.26–7.11) and 2.48 (95% CI, 1.52–4.06) for patients achieving only 0–3 or 4–5 risk factor goals at baseline, respectively, compared with those achieving 6–7 goals. Participants achieving 0–3 or 4–5 goals also had increased risk for the composite outcome of hospitalization for heart failure or CV death (excluding fatal stroke) (HR 2.89 [1.82–4.57] and 1.90 [1.31–2.78], respectively) and 3-point major adverse CV events (HR 2.21 [1.53–3.19] and 1.42 [1.06–1.89]). Empagliflozin significantly reduced these outcomes across all risk factor control categories (P > 0.05 for treatment-by-subgroup interactions). Conclusions Cardiovascular risk in EMPA-REG OUTCOME was inversely associated with baseline CV risk factor control. Empagliflozin’s cardioprotective effect was consistent regardless of multiple baseline risk factor control.

OBJECTIVE The Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial (ClinicalTrials.gov reg. no. NCT01179048) demonstrated a reduced risk of cardiovascular (CV) events for patients with type 2 diabetes who received the glucagon-like peptide 1 receptor agonist liraglutide versus placebo. The mechanisms behind this CV benefit remain unclear. We aimed to identify potential mediators for the CV benefit observed with liraglutide in the LEADER trial. RESEARCH DESIGN AND METHODS We performed exploratory analyses to identify potential mediators of the effect of liraglutide on major adverse CV events (MACE; composite of CV death, nonfatal myocardial infarction, or nonfatal stroke) from the following candidates: glycated hemoglobin (HbA1c), body weight, urinary albumin-to-creatinine ratio (UACR), confirmed hypoglycemia, sulfonylurea use, insulin use, systolic blood pressure, and LDL cholesterol. These candidates were selected as CV risk factors on which liraglutide had an effect in LEADER such that a reduction in CV risk might result. We used two methods based on a Cox proportional hazards model and the new Vansteelandt method designed to use all available information from the mediator and to control for confounding factors. RESULTS Analyses using the Cox methods and Vansteelandt method indicated potential mediation by HbA1c (up to 41% and 83% mediation, respectively) and UACR (up to 29% and 33% mediation, respectively) on the effect of liraglutide on MACE. Mediation effects were small for other candidates. CONCLUSIONS These analyses identify HbA1c and, to a lesser extent, UACR as potential mediators of the CV effects of liraglutide. Whether either is a marker of an unmeasured factor or a true mediator remains a key question that invites further investigation.

Background There is uncertainty on how empagliflozin (EMPA) reduces blood pressure (BP), and in particular the potential role for changes in weight and haematocrit in mediating these effects. Purpose To assess the contributions of changes in weight and haematocrit on EMPA induced changes in BP in patients with type 2 diabetes mellitus (T2DM) in the EMPA-BP and EMPA-REG OUTCOME trials. Methods Patients received placebo (PBO), EMPA 10 mg or EMPA 25 mg. In EMPA-BP (12-week study), 823 patients with T2DM and hypertension (mean [SD] age 60.2 [9.0] years, HbA1c 7.90 [0.74] %, BMI 32.6 [5.1] kg/m2) were studied. In EMPA-REG OUTCOME, of the 7,020 treated patients with T2DM and cardiovascular disease (mean [SD] age 63.1 [8.6] years, HbA1c 8.07 [0.85] %, BMI 30.6 [5.3] kg/m2), 95.0% were on anti-hypertensive treatment at baseline. ANCOVA/MMRM models were applied to assess changes in systolic BP (SBP) at week 12 associated with, and independent of, changes in weight and haematocrit (Hct). SBP measurements are based on mean 24-h measurements from an ambulatory blood pressure monitoring (ABPM) device in EMPA-BP and seated office measurements in EMPA-REG OUTCOME. Results Mean (SD) baseline SBP was 131.7 (11.8), 131.3 (13.0) and 131.2 (12.1) mmHg in the PBO, EMPA 10 mg and EMPA 25 mg groups, respectively in EMPA-BP (mean 24-h SBP) and 135.8 (17.2), 134.9 (16.8) and 135.6 (17.0) mmHg (office SBP), respectively in EMPA-REG OUTCOME. In these relatively young patients with T2DM and mildly elevated mean SBP, EMPA reduced mean SBP by 3.4–4.2 mmHg compared with PBO (table) at week 12. Mean (SE) weight was reduced with EMPA (10 and 25mg) vs PBO treatment by −1.5 (0.2) kg and −2.0 (0.2) kg in EMPA-BP and by −1.2 (0.1) kg and −1.5 (0.1) kg in EMPA-REG OUTCOME at week 12. Mean (SE) haematocrit was increased by 2.1 (0.2) % and 1.8 (0.2) % versus placebo in EMPA-BP and by 2.2 (0.1) % and 2.5 (0.1) % in EMPA-REG OUTCOME with EMPA 10 mg and EMPA 25 mg, respectively. Weight loss accounted for 21–24% of the SBP reduction with EMPA treatment in EMPA-BP and 9–11% in EMPA-REG OUTCOME. Changes in Hct accounted for negligible (between −10% to 1%) SBP reduction with EMPA. Conclusion The reduction in SBP is modestly mediated through a reduction in weight. There was no meaningful effect of EMPA induced changes in Hct on SBP. Results were consistent using ABPM or office SBP. These findings suggest that EMPA's effects on SBP are likely mediated through other mechanisms such as natriuresis or reduction in arterial stiffness.

Aims Atrial fibrillation (AF) is common in patients with diabetes and heart failure (HF) and increases the future risk of adverse cardiovascular (CV) outcomes. This analysis from the EMPA-REG OUTCOME trial explores CV and renal outcomes in patients with vs. without AF at baseline and assesses the benefits of empagliflozin. Methods and results Analyses were conducted on patients distinguished by the presence (n = 389) or absence (n = 6631) of AF at baseline. Outcome events were more frequent in patients with AF than those without AF. Empagliflozin compared to placebo reduced CV death or HF hospitalisation consistently in patients with AF [hazard ratio (HR) 0.58, 95% confidence interval (CI) 0.36-0.92] and without AF (HR 0.67, 95% CI 0.55-0.82, Pinteraction = 0.56). Similar results were observed for the components of this endpoint, all-cause mortality, new or worsening nephropathy, first introduction of loop diuretics, or occurrence of oedema. The absolute number of prevented events was higher in patients with AF, resulting in larger absolute treatment effects of empagliflozin. New loop diuretics or oedema were associated with increased rates of subsequent events, and rates appeared lower in those randomised to empagliflozin. Conclusions In patients with type 2 diabetes mellitus and established CV disease, those with AF at baseline had higher rates of adverse HF outcomes than those without AF. Irrespective of the presence of AF, empagliflozin reduced HF-related and renal events. The absolute number of prevented events is higher in patients with AF than without AF. Patients with diabetes, CV disease and AF may especially benefit from use of empagliflozin.

Objectives Serum markers of iron storage have been linked to type 2 diabetes; however, the mechanism underlying this association is unclear. In pregnancy, increased serum ferritin has been reported in women with gestational diabetes (GDM), a patient population at high risk of future type 2 diabetes. However, in the years after pregnancy, it is not known if ferritin relates to their diabetes risk or the pathophysiologic determinants thereof (insulin sensitivity and beta-cell function). Therefore, we sought to characterize the relationship between ferritin and glucose homeostasis in the early postpartum years in women with and without recent GDM. Methods At both 1 and 3 years postpartum, 340 women (105 with recent GDM) underwent serum ferritin measurement and an oral glucose tolerance test that enabled assessment of insulin sensitivity and/or resistance (Matsuda index and Homeostasis Model Assessment [HOMA-IR]), beta-cell function (Insulin Secretion-Sensitivity Index-2 and insulinogenic index/HOMA-IR) and glucose tolerance. Results Serum ferritin did not differ between women who had GDM and their peers at either 1 or 3 years postpartum. Baseline-adjusted change in ferritin between 1 and 3 years correlated with the concomitant change in C-reactive protein (r=0.21, p=0.0002) but was not associated with measures of insulin sensitivity and/or resistance, beta-cell function or glycemia. On adjusted analyses, neither baseline ferritin nor its change from 1 to 3 years was independently associated with any of the following metabolic outcomes at 3-years postpartum: Matsuda index, HOMA-IR, Insulin Secretion-Sensitivity Index-2, insulinogenic index/HOMA-IR, fasting glucose, 2-h glucose or glucose intolerance. Conclusions Serum ferritin is not associated with glucose homeostasis in the early years after a GDM pregnancy.

Background: SGLT2 (sodium-glucose cotransporter 2) inhibitors lower cardiovascular events in type 2 diabetes mellitus but whether they promote direct cardiac effects remains unknown. We sought to determine if empagliflozin causes a decrease in left ventricular (LV) mass in people with type 2 diabetes mellitus and coronary artery disease. Methods: Between November 2016 and April 2018, we recruited 97 individuals ≥40 and ≤80 years old with glycated hemoglobin 6.5% to 10.0%, known coronary artery disease, and estimated glomerular filtration rate ≥60mL/min/1.73m 2 . The participants were randomized to empagliflozin (10 mg/day, n=49) or placebo (n=48) for 6 months, in addition to standard of care. The primary outcome was the 6-month change in LV mass indexed to body surface area from baseline as measured by cardiac magnetic resonance imaging. Other measures included 6-month changes in LV end-diastolic and -systolic volumes indexed to body surface area, ejection fraction, 24-hour ambulatory blood pressure, hematocrit, and NT-proBNP (N-terminal pro b-type natriuretic peptide). Results: Among the 97 participants (90 men [93%], mean [standard deviation] age 62.8 [9.0] years, type 2 diabetes mellitus duration 11.0 [8.2] years, estimated glomerular filtration rate 88.4 [16.9] mL/min/1.73m 2 , LV mass indexed to body surface area 60.7 [11.9] g/m 2 ), 90 had evaluable imaging at follow-up. Mean LV mass indexed to body surface area regression over 6 months was 2.6 g/m 2 and 0.01 g/m 2 for those assigned empagliflozin and placebo, respectively (adjusted difference −3.35 g/m 2 ; 95% CI, −5.9 to −0.81g/m 2 , P =0.01). In the empagliflozin-allocated group, there was significant lowering of overall ambulatory systolic blood pressure (adjusted difference −6.8mmHg, 95% CI −11.2 to −2.3mmHg, P =0.003), diastolic blood pressure (adjusted difference −3.2mmHg; 95% CI, −5.8 to −0.6mmHg, P =0.02) and elevation of hematocrit ( P =0.0003). Conclusions: Among people with type 2 diabetes mellitus and coronary artery disease, SGLT2 inhibition with empagliflozin was associated with significant reduction in LV mass indexed to body surface area after 6 months, which may account in part for the beneficial cardiovascular outcomes observed in the EMPA-REG OUTCOME (BI 10773 [Empagliflozin] Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) trial.

ContextSerum uric acid has been linked to risk of type 2 diabetes (T2DM), but debate persists as to whether it plays a causal role. Indeed, it is unclear if changes in uric acid relate to the pathophysiologic determinants of T2DM (insulin resistance, beta-cell dysfunction), as would be expected if causal.ObjectiveTo evaluate the impact of changes in uric acid over 2 years on changes in insulin sensitivity, beta-cell function, and glycemia in women with and without recent gestational diabetes (GDM), a model of the early natural history of T2DM.Design/Setting/ParticipantsAt both 1 and 3 years postpartum, 299 women (96 with recent GDM) underwent uric acid measurement and oral glucose tolerance tests that enabled assessment of insulin sensitivity/resistance (Matsuda index, homeostasis model assessment of insulin resistance [HOMA-IR]), beta-cell function (insulin secretion-sensitivity index-2 [ISSI-2], insulinogenic index/HOMA-IR [IGI/HOMA-IR]), and glucose tolerance.ResultsWomen with recent GDM had higher serum uric acid than their peers at both 1 year (281 ± 69 vs 262 ± 58 µmol/L, P = 0.01) and 3 years postpartum (271 ± 59 vs 256 ± 55 µmol/L, P = 0.03), coupled with lower insulin sensitivity, poorer beta-cell function, and greater glycemia (all P < 0.05). However, on fully adjusted analyses, neither uric acid at 1 year nor its change from 1 to 3 years was independently associated with any of the following metabolic outcomes at 3 years postpartum: Matsuda index, HOMA-IR, ISSI-2, IGI/HOMA-IR, fasting glucose, 2-hour glucose, or glucose intolerance.ConclusionSerum uric acid does not track with changes over time in insulin sensitivity, beta-cell function, or glycemia in women with recent GDM, providing evidence against causality in its association with diabetes.

Context Chronic inflammation arising from adipose tissue macrophage (ATM) activation may be central in type 2 diabetes etiology. Our objective was to assess the longitudinal associations of soluble CD163 (sCD163), a novel biomarker of ATM activation, with insulin sensitivity, β-cell function, and dysglycemia in high-risk subjects. Methods Adults at risk for type 2 diabetes in the Prospective Metabolism and Islet Cell Evaluation (PROMISE) study had 3 assessments over 6 years (n = 408). Levels of sCD163 were measured using fasting serum. Insulin sensitivity was assessed by HOMA2-%S and the Matsuda index (ISI). β-cell function was determined by insulinogenic index (IGI) over HOMA-IR and insulin secretion-sensitivity index-2 (ISSI-2). Incident dysglycemia was defined as the onset of impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes. Generalized estimating equations (GEE) evaluated longitudinal associations of sCD163 with insulin sensitivity, β-cell function, and incident dysglycemia adjusting for demographic and lifestyle covariates. Areas under receiver-operating-characteristic curve (AROC) tested whether sCD163 improved dysglycemia prediction in a clinical model. Results Longitudinal analyses showed significant inverse associations between sCD163 and insulin sensitivity (% difference per standard deviation increase of sCD163 for HOMA2-%S (β = −7.01; 95% CI, −12.26 to −1.44) and ISI (β = −7.60; 95% CI, −11.09 to −3.97) and β-cell function (ISSI-2 (β = −4.67; 95 %CI, −8.59 to −0.58) and IGI/HOMA-IR (β = −8.75; 95% CI, −15.42 to −1.56)). Increased sCD163 was associated with greater risk for incident dysglycemia (odds ratio = 1.04; 95% CI, 1.02-1.06; P < 0.001). Adding sCD163 data to a model with clinical variables improved prediction of incident dysglycemia (AROC=0.6731 vs 0.638; P < 0.05). Conclusions sCD163 was longitudinally associated with core disorders that precede the onset of type 2 diabetes.

Objective The risks of cardio-renal complications of diabetes increase with age. In the EMPA-REG OUTCOME® trial, empagliflozin reduced cardiovascular (CV) mortality by 38% in patients with type 2 diabetes (T2D) and CV disease. Here we compare outcomes with empagliflozin in older patients in EMPA-REG OUTCOME. Methods Patients with T2D and CV disease were randomised to empagliflozin 10 or 25 mg, or placebo plus standard of care. In post hoc analyses, risks of 3-point major adverse CV events (3P-MACE: composite of CV death, non-fatal myocardial infarction (MI) or non-fatal stroke), CV death, hospitalisation for heart failure, all-cause mortality, all-cause hospitalisation and incident/worsening nephropathy were evaluated for empagliflozin versus placebo by baseline age ( Results Effect of empagliflozin on all outcomes was consistent across age categories (P ≥ 0.05 for interactions) except 3P-MACE. The 3P-MACE hazard ratios (HRs) were 1.04 (95% confidence interval [CI] 0.84, 1.29), 0.74 (0.58, 0.93) and 0.68 (0.46, 1.00) in patients aged Conclusions In the EMPA-REG OUTCOME trial, empagliflozin reduced risks of CV mortality, heart failure and renal outcomes, supporting its cardio-renal benefits in older patients.

Objective: apoA1 (apolipoprotein A-1) is the main lipoprotein associated with HDL (high-density lipoprotein) cholesterol. It was recently reported that intravenous infusion of apoA1 could lower insulin resistance in pregnant rats, leading to the suggestion that apoA1 could provide a target for reducing pregnancy-induced insulin resistance and the risk of gestational diabetes mellitus (GDM) in humans. However, the effects of apoA1 on insulin resistance and risk of GDM in human pregnancy are not known. Thus, we sought to systematically evaluate the relationships of apoA1 with glucose homeostasis and metabolic function in pregnant women. Approach and Results: In this study, 870 pregnant women were recruited in late second trimester and underwent metabolic characterization, including an oral glucose tolerance test on which 214 were diagnosed with GDM. Metabolic characterization included assessment of glucose tolerance, insulin sensitivity/resistance (Matsuda index, homeostasis model assessment of insulin resistance), pancreatic β-cell function, lipids (LDL [low-density lipoprotein] cholesterol, HDL cholesterol, triglycerides, apoB [apolipoprotein B], and apoA1), CRP (C-reactive protein), and adiponectin. Serum apoA1 was strongly correlated with HDL (r=0.79, P P =0.0004) but showed no association with measures of insulin sensitivity/resistance, β-cell function, glycemia, or CRP. There were no significant differences across apoA1 tertiles in mean adjusted Matsuda index ( P =0.24), homeostasis model assessment of insulin resistance ( P =0.08), or area under the glucose curve on the oral glucose tolerance test ( P =0.96). Moreover, there were no differences in risk of GDM across tertiles of apoA1, both before ( P =0.67) and after covariate adjustment ( P =0.78). Conclusions: Serum apoA1 is not associated with insulin resistance or the risk of GDM in human pregnancy.

In patients with type 2 diabetes mellitus (T2DM) and cardiovascular (CV) disease, empagliflozin (EMPA) decreased progression of chronic kidney disease (CKD), likely via a reduction in intraglomerular pressure. Due to prevalent comorbidities, such as hypertension and albuminuria, patients often receive other agents that alter intrarenal hemodynamics, including angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARBs), calcium channel blockers (CCBs) and diuretics. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also be used by some individuals. In this exploratory, non-prespecified analysis, we investigated whether the kidney benefits of EMPA are altered in individuals already using the medications in these categories. In the BI 10773 (Empagliflozin) Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME®) trial, 7020 patients were essentially equally randomized to EMPA 10 mg, 25 mg or placebo added to their standard care. Differences in risk of incident or worsening nephropathy for pooled EMPA vs placebo across subgroups by baseline background medications (to which patients were not randomized) were assessed using a Cox proportional hazards model. Risk reductions in incident or worsening nephropathy with EMPA were consistent across medication subgroups, with no heterogeneity of treatment effect. As a representative example, the risk for acute renal failure was overall slightly increased in patients using ACEi/ARBs in all groups (placebo, EMPA 10 mg or EMPA 25 mg) but incidence rates were numerically lower in those assigned to EMPA. Similar patterns were observed for other medications included in this analysis. Thus, EMPA may assist to prevent CKD progression in patients with T2DM with CV disease, irrespective of common background medications that alter intrarenal hemodynamics, and without increasing acute renal adverse events.

OBJECTIVE To investigate the efficacy, safety, and tolerability of oral semaglutide added to insulin with or without metformin. RESEARCH DESIGN AND METHODS Patients with type 2 diabetes uncontrolled on insulin with or without metformin were randomized to oral semaglutide 3 mg (N = 184), 7 mg (N = 182), or 14 mg (N = 181) or to placebo (N = 184) in a 52-week, double-blind trial. End points were change from baseline to week 26 in HbA1c (primary) and body weight (confirmatory secondary). Two estimands were defined: treatment policy (effect regardless of trial product discontinuation or rescue medication) and trial product (effect assuming trial product continuation without rescue medication) in randomized patients. RESULTS Oral semaglutide was superior to placebo in reducing HbA1c (estimated treatment difference [ETD] –0.5% [95% CI –0.7, –0.3], –0.9% [–1.1, –0.7], and –1.2% [–1.4, –1.0] for 3, 7, and 14 mg, respectively; P < 0.001) and body weight (ETD −0.9 kg [95% CI −1.8, −0.0], −2.0 kg [−3.0, −1.0], and −3.3 kg [−4.2, −2.3]; P = 0.0392 for 3 mg, P ≤ 0.0001 for 7 and 14 mg) at week 26 (treatment policy estimand). Significantly greater dose-dependent HbA1c and body weight reductions versus placebo were achieved with oral semaglutide at weeks 26 and 52 (both estimands). The most frequent adverse event with oral semaglutide was nausea (11.4–23.2% of patients vs. 7.1% with placebo; mostly mild to moderate). CONCLUSIONS Oral semaglutide was superior to placebo in reducing HbA1c and body weight when added to insulin with or without metformin in patients with type 2 diabetes. The safety profile was consistent with other glucagon-like peptide 1 receptor agonists.

Recent phase 3 clinical trials have evaluated the impact of adding sodium-glucose co-transporter (SGLT) inhibitors to the type 1 diabetes armamentarium. These trials studied SGLT2 inhibitors (dapagliflozin and empagliflozin) and a dual SGLT1 and SGLT2 inhibitor (sotagliflozin), and demonstrated that these oral non-insulin antihyperglycaemic medications are able not only to improve glycaemic control, but also to reduce body weight and extend time in range without increasing rates of hypoglycaemia in type 1 diabetes. Diabetic ketoacidosis (DKA) is a feature of type 1 diabetes and the risk is increased when SGLT inhibitors are used in type 1 diabetes. To minimize the risk of DKA and still gain the multiple benefits, we developed the "STOP DKA Protocol ", an easily accessible and practical tool, that provides a risk mitigation strategy for reducing DKA in patients with type 1 diabetes being treated with SGLT inhibitors.

Background and objectives Glomerular hyperfiltration has been considered to be a contributing factor to the development of diabetic kidney disease (DKD). To address this issue, we analyzed GFR follow-up data on participants with type 1 diabetes undergoing 125 I-iothalamate clearance on entry into the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications study. Design, setting, participants, & measurements This was a cohort study of DCCT participants with type 1 diabetes who underwent an 125 I-iothalamate clearance (iGFR) at DCCT baseline. Presence of hyperfiltration was defined as iGFR levels ≥140 ml/min per 1.73 m 2 , with secondary thresholds of 130 or 150 ml/min per 1.73 m 2 . Cox proportional hazards models assessed the association between the baseline hyperfiltration status and the subsequent risk of reaching an eGFR 2 . Results Of the 446 participants, 106 (24%) had hyperfiltration (iGFR levels ≥140 ml/min per 1.73 m 2 ) at baseline. Over a median follow-up of 28 (interquartile range, 23, 33) years, 53 developed an eGFR 2 . The cumulative incidence of eGFR 2 at 28 years of follow-up was 11.0% among participants with hyperfiltration at baseline, compared with 12.8% among participants with baseline GFR 2 . Hyperfiltration was not significantly associated with subsequent risk of developing an eGFR 2 in an unadjusted Cox proportional hazards model (hazard ratio, 0.83; 95% confidence interval, 0.43 to 1.62) nor in an adjusted model (hazard ratio, 0.77; 95% confidence interval, 0.38 to 1.54). Application of alternate thresholds to define hyperfiltration (130 or 150 ml/min per 1.73 m 2 ) showed similar findings. Conclusions Early hyperfiltration in patients with type 1 diabetes was not associated with a higher long-term risk of decreased GFR. Although glomerular hypertension may be a mechanism of kidney injury in DKD, higher total GFR does not appear to be a risk factor for advanced DKD.

Aims To evaluate the short‐term cost‐effectiveness of insulin degludec (degludec) vs insulin glargine 100 units/mL (glargine U100) from a Canadian public healthcare payer perspective in patients with type 2 diabetes (T2D) who are at high risk of cardiovascular events and hypoglycaemia. Materials and methods A decision analytic model was developed to estimate costs (2017 Canadian dollars [CAD]) and clinical outcomes (quality‐adjusted life years [QALYs]) with degludec vs glargine U100 over a 2‐year time horizon. The model captured first major adverse cardiovascular event, death, severe hypoglycaemia and insulin dosing. Clinical outcomes were informed by a post hoc subgroup analysis of the DEVOTE trial (NCT01959529), which compared the cardiovascular safety of degludec and glargine U100 in patients with T2D who are at high cardiovascular risk. High hypoglycaemia risk was defined as the top quartile of patients (n = 1887) based on an index of baseline hypoglycaemia risk factors. Results In patients at high hypoglycaemia risk, degludec was associated with mean cost savings (CAD 129 per patient) relative to glargine U100, driven by a lower incidence of non‐fatal myocardial infarction, non‐fatal stroke and severe hypoglycaemia, which offset the slightly higher cost of treatment with degludec. A reduced risk of cardiovascular death and severe hypoglycaemia resulted in improved effectiveness (+0.0132 QALYs) with degludec relative to glargine U100. In sensitivity analyses, changes to the vast majority of model parameters did not materially affect model outcomes. Conclusion Over a 2‐year period, degludec improved clinical outcomes at a lower cost as compared to glargine U100 in patients with T2D at high risk of cardiovascular events and hypoglycaemia.

Cardiovascular risk reduction with liraglutide and semaglutide in patients with type 2 diabetes was demonstrated in the LEADER (ClinicalTrials.gov: {"type":"clinical-trial","attrs":{"text":"NCT01179048","term_id":"NCT01179048"}}NCT01179048) and SUSTAIN 6 (ClinicalTrials.gov: {"type":"clinical-trial","attrs":{"text":"NCT01720446","term_id":"NCT01720446"}}NCT01720446) cardiovascular outcome trials. This post hoc analysis assessed the impact of diabetes duration (

The evolution of basal insulin therapy over the past 100 years since the discovery of insulin is a testimony to the biomedical bench-to-bedside process, wherein incremental advances in the basic sciences are progressively translated over time into a series of enhancements in clinical care, each building upon the success of its predecessors. The emergence of recombinant DNA technology and the resultant biosynthesis of human insulin in the 1980s provided the critical capacity to bioengineer designer insulin analogues with pharmacokinetic and pharmacodynamic properties that can better mimic, although not fully replicate, the effects of endogenous insulin secretion. Through these efforts, basal insulin therapy has progressed over this time from first-generation analogues (glargine U-100, detemir) to second-generation analogues (glargine U-300, degludec) to ultra-long-acting formulations that are suitable for administration once weekly (icodec). Each iteration in this progression has represented a step closer towards the goal of replicating the continuous secretion of insulin that normally comprises the basal output of the pancreatic beta-cells between meals, during episodes of fasting and overnight. However, it may be that we may have reached the achievable limit in the context of an "open-loop" approach, such that only with the addition of closed loop control will we be able to achieve physiologic basal insulin replacement. In this review, we will examine the evolution of basal insulin therapy over the past 100 years and its implications for patient care and outcomes in current practice and the future.

AIM To evaluate the effects of empagliflozin versus placebo on subsequent insulin initiation or dosing changes in a large cardiovascular outcomes trial. MATERIALS AND METHODS In EMPA-REG OUTCOME, 7020 patients with type 2 diabetes and cardiovascular disease received empagliflozin 10 mg, 25 mg, or placebo. Median follow-up was 3.1 years. After 12 weeks of treatment, changes in background antihyperglycaemic therapy were permitted. Among insulin-naive patients, we assessed the effects of pooled empagliflozin arms versus placebo on time to initiation of insulin. Among insulin-treated patients, we assessed effects on time to an increase or decrease in insulin dose of more than 20%. RESULTS In 3633 (52%) participants not treated with insulin at baseline, empagliflozin reduced new use of insulin versus placebo by 60% (7.1% vs. 16.4%; adjusted HR 0.40 [95% CI 0.32-0.49]; P

Background Recent studies have suggested that gestational diabetes (GDM) is a heterogeneous condition with distinct subtypes determined by whether the predominant metabolic abnormality is impaired insulin sensitivity or deficient insulin secretion. However, it is not known if the elevated future risk of pre-diabetes/diabetes associated with GDM varies according to these subtypes. Thus, we sought to evaluate maternal metabolic function in the 1st year postpartum in relation to GDM subtypes. Methods In this prospective cohort study conducted in Toronto, Canada, 613 women underwent GDM screening by oral glucose tolerance test (OGTT) in pregnancy, followed by repeat OGTT at both 3-months and 12-months postpartum between 09/2003 and 03/2016. The antepartum OGTT identified 3 groups of women: GDM with predominant sensitivity defect (GDM-sensitivity), GDM with predominant secretion defect (GDM-secretion), and non-GDM. Findings Antepartum findings persisted after pregnancy, with lower insulin sensitivity in GDM-sensitivity (Matsuda index; HOMA-IR) and lower insulin secretion in GDM-secretion (Stumvoll first-phase; insulinogenic index (IGI)) at both 3-months and 12-months (all p

Treatment with empagliflozin (EMPA) improves cardiorenal outcomes, but also reduces liver fat content in individuals with both type 2 diabetes (T2D) and nonalcoholic fatty liver disease (NAFLD). Thus, we evaluated the effects of EMPA vs. placebo (PLAC) on NAFLD-related steatosis and fibrosis risks and the relation of fibrosis risk to cardiorenal outcomes in individuals with T2D in the randomized controlled trial EMPA-REG OUTCOME. The trial enrolled 7020 people with T2D and cardiovascular disease for treatment with 10 or 25 mg daily EMPA or PLAC. Post-hoc, we derived the Dallas Steatosis Index (DSI) and NAFLD fibrosis score (NFS) to assess the risks of steatosis and fibrosis from baseline to week 164 of treatment, respectively. Changes from baseline in DSI and NFS were examined by mixed model repeated measures analysis, and effects on cardiovascular and all-cause death, hospitalization for heart failure and nephropathy by Cox regression across fibrosis risk categories. At baseline, 72% of participants had high risk of steatosis (DSI probability of >50%; mean, 0.74±0.00 and 23% had high risk of advanced fibrosis (NFS >0.675; mean, 1.26±0.01. Overall DSI (logit) decreased with EMPA compared to PLAC at all timepoints (p In conclusion, EMPA may attenuate NAFLD-related steatosis as well as fibrosis progression specifically in individuals at risk of advanced fibrosis, and improves cardiorenal outcomes as well as all-cause mortality independent of fibrosis risk category.

Background: Sodium-glucose cotransporter 2 inhibitors reduce the risk, and progression, of diabetic kidney disease. We hypothesized that sodium-glucose cotransporter 2 inhibitors could similarly improve the microvascular complication of neuropathy. Methods: The CREDENCE trial randomized participants with type 2 diabetes and albuminuria to canagliflozin or placebo. Neuropathy events were defined as any reported adverse event with a Medical Dictionary for Regulatory Activities (MedDRA) term consistent with peripheral or autonomic neuropathy. The effect of canagliflozin on neuropathy events was calculated by Cox regression. In secondary analyses the endpoint was restricted to sensorimotor polyneuropathy, diabetic neuropathy, or non-autonomic neuropathy events, and subgroups were analysed. P-values adjusted for multiplicity using the Holm-Bonferroni correction were derived for the subgroup analyses. Results: Half (48.8%) of the 4401 participants had a diagnosis of neuropathy at baseline. Over a median of 2.45 years follow up, 657 people experienced a neuropathy event (63.2 per 1000 patient-years). The incidence of neuropathy events was similar in people randomized to canagliflozin and placebo (334/2202 vs. 323/2199; HR 1.04, 95% CI 0.89 to 1.21, p=0.66). Canagliflozin had no impact on sensorimotor polyneuropathy (HR 0.93, 95% CI 0.69 to 1.25, p=0.63), diabetic neuropathy (HR 0.91, 95% CI 0.68 to 1.22, p=0.52), or non-autonomic neuropathy (HR 1.03, 95% CI 0.87 to 1.21, p=0.77). The lack of effect on neuropathy events was consistent in subgroup analyses. Conclusions: Canagliflozin did not affect the risk of neuropathy events in the CREDENCE trial despite clear benefits for nephropathy, cardiovascular disease and glycemic control. Disclosure J.

Background: Diabetes is the most common cause of kidney disease in people requiring renal replacement therapy (RRT). RRT is projected to dramatically increase globally, with the greatest increase in Asia. CREDENCE showed canagliflozin reduces kidney and cardiovascular (CV) events in individuals with type 2 diabetes (T2DM) and chronic kidney disease (CKD). Methods: We explored canagliflozin efficacy across geographic regions. A Cox proportional-hazards model was used to analyze the primary outcome (composite of end-stage kidney disease [dialysis, transplantation, or a sustained eGFR of Results: A total of 4401 participants were enrolled across North America (n=1182, 27%), Central and South America (n=941, 21%), Eastern Europe (n=947, 21%), Western Europe (n=421, 10%), Asia (n=749, 17%), and Other (n=161, 4%). Placebo event rates ranged widely, with 32 and 77 events/1000 patient-years in Western Europe and Asia, respectively. Canagliflozin consistently reduced the risk of the primary outcome in all geographic regions (see Figure, previously reported data on race also included). Conclusions: Event rates varied two-fold across regions and needs further study. Canagliflozin reduces the risk of kidney and CV events in all geographic regions. Disclosure K. Cardoza: None. B.

Background: Canagliflozin reduces the incidence of kidney and cardiovascular events in people with type 2 diabetes and chronic kidney disease (CKD). We assessed the effects of canagliflozin according to age and sex in a randomized, placebo-controlled trial. Methods: The CREDENCE study randomized participants with type 2 diabetes and albuminuric CKD. The effects of canagliflozin on the primary outcome (a composite of kidney failure, a doubling of the serum creatinine level, or death from kidney or cardiovascular causes), and secondary outcomes were evaluated by age at baseline ( Results: Of the 4401 participants, 33.5%, 42.1%, and 24.4% were Conclusion: Canagliflozin reduces the risk of kidney and cardiovascular events in people with type 2 diabetes and CKD with consistent effects and no differences in safety outcomes across subgroups defined by age and sex.

Aims Loop diuretics (LD) relieve symptoms and signs of congestion due to heart failure (HF), but many patients prescribed LD do not have such a diagnosis. We studied the relationship between HF diagnosis, use of LD, and outcomes in patients with type 2 diabetes mellitus (T2DM) enrolled in the EMPA-REG OUTCOME trial. Methods and results The relationship between HF diagnosis, use of LD, and outcomes was evaluated in four patient subgroups with T2DM: (i) investigator-reported HF on LD, (ii) investigator-reported HF not on LD, (iii) no HF on LD, and (iv) no HF and not on LD, and we assessed their risk of cardiovascular events. Of 7020 participants, 706 (10%) had a diagnosis of HF at baseline, of whom 334 were prescribed LD. However, 755 (11%) patients who did not have a diagnosis of HF were prescribed LD. Compared to those with neither HF nor prescribed LD (reference group; placebo), those with both HF and receiving LD had the highest rates for all-cause [hazard ratio (HR) (95% confidence interval) 3.19 (2.03-5.01)] and cardiovascular mortality [3.83 [(2.28-6.44)], and HF hospitalizations [9.51 (5.61-16.14)]. Patients without HF but prescribed LD had higher rates for all three outcomes [1.62 (1.10-2.39); 1.97 (1.26-3.08); 3.20 (1.90-5.39)], which were similar to patients with HF who were not receiving LD [1.42 (0.78-2.57); 1.56 (0.78-3.11); 3.00 (1.40-6.40)]. Empagliflozin had similar benefits regardless of subgroup (P for interaction >0.1 for all outcomes). Conclusion Patients with T2DM prescribed LD are at greater risk of cardiovascular events even if they are not reported to have HF; this might reflect under-diagnosis. Empagliflozin was similarly effective in all subgroups investigated.
