Sodium-Glucose Cotransporter 2 Inhibitors, All-Cause Mortality, and Cardiovascular Outcomes in Adults with Type 2 Diabetes: A Bayesian Meta-Analysis and Meta-Regression

Atherothrombotic Outcomes After Sodium-Glucose Cotransporter 2 Inhibitors Versus Dipeptidyl Peptidase-4 Inhibitors in Patients With Type 2 Diabetes: A Territory-Wide Retrospective Cohort Study

BACKGROUND

This study compared the risks of atherothrombotic major adverse cardiovascular events in patients with type 2 diabetes taking SGLT2 (sodium-glucose cotransporter 2) inhibitors to those taking DPP-4 (dipeptidyl peptidase-4) inhibitors.

METHODS AND RESULTS

All adult patients (≥18 years of age) with type 2 diabetes and newly prescribed with SGLT2 inhibitors or DPP-4 inhibitors across all public hospitals in Hong Kong between January 2015 and December 2019 were included. Patients were propensity matched in a 1:1 ratio using a caliper distance of 0.2 without replacement. The primary outcome was atherothrombotic major adverse cardiovascular events as a composite outcome of cardiovascular mortality, nonfatal stroke, and nonfatal myocardial infarction. Time-to-first event analysis was conducted using a univariable Cox proportional hazards model. Primary and secondary analyses were repeated using stabilized inverse probability weighting and propensity score adjustment in the complete case cohort. A total of 20 642 patients (10 321 SGLT2 inhibitors versus 10 321 DPP-4 inhibitors) were included in the final analysis. The mean age was 59±11 years, and 13 142 (63.7%) were men. The median follow-up period was 2.9 years. The use of SGLT2 inhibitors was associated with a significant reduction in atherothrombotic major adverse cardiovascular events (453 [4.4%] versus 719 [7.0%]; hazard ratio, 0.64 [95% CI, 0.57-0.72]; P<0.001) compared with DPP-4 inhibitors. SGLT2 inhibitors were independently associated with reduced all-cause mortality, cardiovascular mortality, stroke, myocardial infarction, and incident dialysis (all P values <0.001).

CONCLUSIONS

SGLT2 inhibitors in patients with diabetes were independently associated with reduction in atherothrombotic major adverse cardiovascular events, all-cause mortality, cardiovascular mortality, myocardial infarction, stroke, and incident dialysis, compared with DPP-4 inhibitors.

Effect of sodium glucose cotransporter-2 inhibitors (SGLT-2is) on the clinical outcomes of patients with diabetic atrial fibrillation

BACKGROUND

Diabetes mellitus (DM) and atrial Fibrillation (AF) are among the most common health issues. They are responsible for the highest rates of morbidity and mortality. The importance of sodium glucose cotransporter-2 inhibitors (SGLT-2is) in treating DM has increased significantly in recent years. In our article, we aimed to evaluate the effect of SGLT-2i on the clinical outcomes of AF patients with DM.

METHODS

Our study is a retrospective, observational study. The patients with AF and DM were divided into two groups: those using SGLT-2i or not using SGLT-2i, and 3-year follow-up results were examined. The endpoints of the study were defined as all-cause death, the development of myocardial infarction (MI), major bleeding requiring hospitalization, and an ischemic cerebrovascular event (CVE). Differences between groups according to SGLT-2i use were analyzed.

RESULTS

The study included 485 patients, 205 (42.3%) of whom were male and had an average age of 70.7 ± 9.7 years. A total of 138 of 485 patients (28.5%) received SGLT-2i. All-cause mortality was lower in the group receiving SGLT-2i (p < 0.001). Similarly, a significant reduction in major bleeding events was observed among those who received SGLT-2i treatment (p = 0.009). The incidence of CVEs was lower among SGLT-2i recipients, but the difference was not statistically significant (p = 0.066). SGLT2i usage did not mitigate the risk of MI development (p = 0.317).

CONCLUSIONS

In our study, SGLT-2i treatment was associated with a significant reduction in all-cause mortality and major bleeding in diabetic AF patients. Our study provides evidence of the clinical benefit of SGLT-2i in AF patients.

Expanding access to sodium-glucose cotransporter 2 inhibitors (SGLT2i) in the Ministry of Health Malaysia - a multiple HTA approach

OBJECTIVES

Ministry of Health (MOH) Malaysia stakeholders seek primary care access to sodium-glucose cotransporter 2 inhibitor (SGLT2i). Addressing this required a complex decision, selecting among three SGLT2i for two different indications and two practice settings. The options include expanding the existing SGLT2i (empagliflozin) in the MOH Medicines Formulary to primary care and/or having dapagliflozin and/or luseogliflozin as alternatives. This study aimed to conduct a multiple health technology assessment (HTA) to determine the SGLT2i of choice for the MOH setting.

METHODS

The clinical benefits of SGLT2i were assessed through a systematic literature review and affordability was assessed through the development of three budget impact analysis models simulating seventy scenarios. Each model varied by prescribing indications, restrictions, and SGLT2i involved (M1: glycemic control, HbA1c between 6.5 percent and 10 percent, empagliflozin-dapagliflozin-luseogliflozin; M2: cardiovascular benefits, HbA1c less than 10 percent, empagliflozin-dapagliflozin; M3: a composite of M1 and M2). The outcome of the HTA was presented to the MOH decision-makers.

RESULTS

Although there was no significant difference in glycemic control between the SGLT2i, differences exist in cardiovascular benefits conferred. Despite having scenarios with lower net budget impact (NBI) in the M1, M2, and M3 models, decision-makers decided to expand empagliflozin use to primary care setting and add dapagliflozin for hospital-only setting for both indications [NBI of $4.38 mil] due to empagliflozin's advantage in reducing risk for cardiovascular death and prior experience of its use in MOH.

CONCLUSIONS

The multiple HTA approach guided the complex decision-making process by providing a holistic understanding of the decision's impact.

Is There a Role for SGLT2 Inhibitors in Patients with End-Stage Kidney Disease?

PURPOSE OF REVIEW

Chronic kidney disease and end-stage kidney disease (ESKD) are well-established risk factors for cardiovascular disease (CVD), the leading cause of mortality in the dialysis population. Conventional therapies, such as statins, blood pressure control, and renin-angiotensin-aldosterone system blockade, have inadequately addressed this cardiovascular risk, highlighting the unmet need for effective treatment strategies. Sodium-glucose transporter 2 (SGLT2) inhibitors have demonstrated significant renal and cardiovascular benefits among patients with type 2 diabetes, heart failure, or CKD at risk of progression. Unfortunately, efficacy data in dialysis patients is lacking as ESKD was an exclusion criterion for all major clinical trials of SGLT2 inhibitors. This review explores the potential of SGLT2 inhibitors in improving cardiovascular outcomes among patients with ESKD, focusing on their direct cardiac effects.

RECENT FINDINGS

Recent clinical and preclinical studies have shown promising data for the application of SGLT2 inhibitors to the dialysis population. SGLT2 inhibitors may provide cardiovascular benefits to dialysis patients, not only indirectly by preserving the remaining kidney function and improving anemia but also directly by lowering intracellular sodium and calcium levels, reducing inflammation, regulating autophagy, and alleviating oxidative stress and endoplasmic reticulum stress within cardiomyocytes and endothelial cells. This review examines the current clinical evidence and experimental data supporting the use of SGLT2 inhibitors, discusses its potential safety concerns, and outlines ongoing clinical trials in the dialysis population. Further research is needed to evaluate the safety and effectiveness of SGLT2 inhibitor use among patients with ESKD.

Addressing disparities in the long-term mortality risk in individuals with non-ST segment myocardial infarction (NSTEMI) by diabetes mellitus status: a nationwide cohort study

AIMS/HYPOTHESIS

The aim of this study was to investigate how diabetes mellitus affects longer term outcomes in individuals presenting to hospital with non-ST segment elevation myocardial infarction (NSTEMI).

METHODS

We analysed data from 456,376 adults hospitalised between January 2005 and March 2019 with NSTEMI from the UK Myocardial Ischaemia National Audit Project (MINAP) registry, linked with Office for National Statistics death reporting. We compared outcomes and quality of care by diabetes status.

RESULTS

Individuals with diabetes were older (median age 74 vs 73 years), were more often of Asian ethnicity (13% vs 4%) and underwent revascularisation (percutaneous coronary intervention or coronary artery bypass graft surgery) (38% vs 40%) less frequently than those without diabetes. The mortality risk for those with diabetes compared with those without was significantly higher at 30 days (HR 1.19, 95% CI 1.15, 1.23), 1 year (HR 1.28, 95% CI 1.26, 1.31), 5 years (HR 1.36, 95% CI 1.34, 1.38) and 10 years (HR 1.39, 95% CI 1.36, 1.42). In individuals with diabetes, higher quality inpatient care, assessed by opportunity-based quality indicator (OBQI) score category ('poor', 'fair', 'good' or 'excellent'), was associated with lower mortality rates compared with poor care (good: HR 0.74, 95% CI 0.73, 0.76; excellent: HR 0.69, 95% CI 0.68, 0.71). In addition, compared with poor care, excellent care in the diabetes group was associated with the lowest mortality rates in the diet-treated and insulin-treated subgroups (diet-treated: HR 0.64, 95% CI 0.61, 0.68; insulin-treated: HR 0.69, CI 0.66, 0.72).

CONCLUSION/INTERPRETATION

Individuals with diabetes experience disparities during inpatient care following NSTEMI. They have a higher risk of long-term mortality than those without diabetes, and higher quality inpatient care may lead to better long-term survival.

Disparities in Use of Novel Diabetes Medications by Insurance: A Nationally Representative Cohort Study

BACKGROUND

Minority racial and ethnic populations have the highest prevalence of type 2 diabetes mellitus but lower use of sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1ra), novel medications that reduce morbidity and mortality. Observed disparities may be due to differences in insurance coverage, which have variable cost-sharing, prior authorization, and formulary restrictions that influence medication access.

OBJECTIVE

To assess whether racial/ethnic differences in SGLT2i and GLP1ra use differ by payer.

DESIGN

Cross-sectional analysis of 2018 and 2019 Medical Expenditure Panel Survey data.

PARTICIPANTS

Adults ≥ 18 years old with diabetes.

MAIN MEASURES

We defined insurance as private, Medicare, or Medicaid using ≥ 7 months of coverage in the calendar year. We defined race/ethnicity as White (non-Hispanic) vs non-White (including Hispanic). The primary outcome was use of ≥ 1 SGLT2i or GLP1ra medication. We used multivariable logistic regression to assess the interaction between payer and race/ethnicity adjusted for cardiovascular, socioeconomic, and healthcare access factors.

KEY RESULTS

We included 4997 adults, representing 24.8 million US adults annually with diabetes (mean age 63.6 years, 48.8% female, 38.8% non-White; 33.5% private insurance, 56.8% Medicare, 9.8% Medicaid). In our fully adjusted model, White individuals with private insurance had significantly more medication use versus non-White individuals (16.1% vs 8.3%, p < 0.001), which was similar for Medicare beneficiaries but more attenuated (14.7% vs 11.0%, p = 0.04). Medication rates were similar among Medicaid beneficiaries (10.0% vs 9.0%, p = 0.74).

CONCLUSIONS

Racial/ethnic disparities in novel diabetes medications were the largest among those with private insurance. There was no disparity among Medicaid enrollees, but overall prescription rates were the lowest. Given that disparities vary considerably by payer, differences in insurance coverage may account for the observed disparities in SGLT2i and GLP1ra use. Future studies are needed to assess racial/ethnic differences in novel diabetes use by insurance formulary restrictions and out-of-pocket cost-sharing.

Effectiveness of Fludrocortisone Plus Hydrocortisone versus Hydrocortisone Alone in Septic Shock: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials

Rationale: The use of hydrocortisone in adult patients with septic shock is controversial, and the effectiveness of adding fludrocortisone to hydrocortisone remains uncertain. Objectives: To assess the comparative effectiveness and safety of fludrocortisone plus hydrocortisone, hydrocortisone alone, and placebo or usual care in adults with septic shock. Methods: A systematic review and a Bayesian network meta-analysis of peer-reviewed randomized trials were conducted. The primary outcome was all-cause mortality at last follow-up. Treatment effects are presented as relative risks (RRs) with 95% credible intervals (CrIs). Placebo or usual care was the reference treatment. Measurements and Main Results: Among 7,553 references, we included 17 trials (7,688 patients). All-cause mortality at last follow-up was lowest with fludrocortisone plus hydrocortisone (RR, 0.85; 95% CrI, 0.72-0.99; 98.3% probability of superiority, moderate-certainty evidence), followed by hydrocortisone alone (RR, 0.97; 95% CrI, 0.87-1.07; 73.1% probability of superiority, low-certainty evidence). The comparison of fludrocortisone plus hydrocortisone versus hydrocortisone alone was based primarily on indirect evidence (only two trials with direct evidence). Fludrocortisone plus hydrocortisone was associated with a 12% lower risk of all-cause mortality compared with hydrocortisone alone (RR, 0.88; 95% CrI, 0.74-1.03; 94.2% probability of superiority, moderate-certainty evidence). Conclusions: In adult patients with septic shock, fludrocortisone plus hydrocortisone was associated with lower risk of all-cause mortality at last follow-up than placebo and hydrocortisone alone. The scarcity of head-to-head trials comparing fludrocortisone plus hydrocortisone versus hydrocortisone alone led our network meta-analysis to rely primarily on indirect evidence for this comparison. Although we undertook several sensitivity analyses and assessments, these findings should be considered while also acknowledging the heterogeneity of included trials.

Sotagliflozin and Kidney Outcomes, Kidney Function, and Albuminuria in Type 2 Diabetes and CKD: A Secondary Analysis of the SCORED Trial

BACKGROUND

In the initial analysis of the Effect of Sotagliflozin on Cardiovascular and Renal Events in Patients with Type 2 Diabetes and Moderate Renal Impairment Who Are at Cardiovascular Risk (SCORED) trial, because of early trial termination and suspension of adjudication, reconciliation of eGFR laboratory data and case report forms had not been completed. This resulted in a small number of kidney composite events and a nominal effect of sotagliflozin versus placebo on this outcome. This exploratory analysis uses laboratory eGFR data, regardless of case report form completion, to assess the effects of sotagliflozin on the predefined kidney composite end point in the SCORED trial and additional cardiorenal composite end points.

METHODS

SCORED was a multicenter, randomized trial evaluating cardiorenal outcomes with sotagliflozin versus placebo in 10,584 patients with type 2 diabetes and CKD. This exploratory analysis used laboratory data to derive the eGFR components and case report form data for the non-laboratory-defined components that together made up the kidney and cardiorenal composites. AKI was also assessed in this dataset.

RESULTS

Using laboratory data, 223 events were identified, and sotagliflozin reduced the risk of the composite of first event of sustained ≥50% decline in eGFR, eGFR <15 ml/min per 1.73 m 2 , dialysis, or kidney transplant with 87 events (1.6%) in the sotagliflozin group and 136 events (2.6%) in the placebo group (hazard ratio [95% confidence interval], 0.62 [0.48 to 0.82]), P < 0.001). Sotagliflozin reduced the risk of a cardiorenal composite end point defined as the abovementioned composite plus cardiovascular or kidney death with 239 events (4.5%) in the sotagliflozin group and 306 events (5.7%) in the placebo group (hazard ratio [95% confidence interval], 0.77 [0.65 to 0.91], P = 0.0023). The results were consistent when using different eGFR decline thresholds and when only including kidney death in composites (all P < 0.01). The incidence of AKI was similar between treatment groups.

CONCLUSIONS

In this exploratory analysis using the complete laboratory dataset, sotagliflozin reduced the risk of kidney and cardiorenal composite end points in patients with type 2 diabetes and CKD.

SGLT2 Inhibitors in Management of Severe Hypomagnesemia in Patients Without Diabetes: A Report of 4 Cases

Sodium/glucose cotransporter 2 (SGLT2) inhibitors have demonstrated a class effect in improving serum magnesium levels in patients with diabetes. Additionally, recent reports have shown their promising beneficial effects in the treatment of refractory hypomagnesemia in patients with diabetes. However, their role in treating hypomagnesemia in patients without diabetes remains unexplored. Here, we report 4 cases of severe and refractory hypomagnesemia that showed dramatic improvement after initiating SGLT2 inhibitors in patients without diabetes. Case 1 had calcineurin inhibitor-associated severe hypomagnesemia. Cases 2, 3, and 4 had refractory hypomagnesemia associated with platinum-based chemotherapy with or without gastrointestinal losses. Case 1 was able to withdraw from high-dose oral magnesium supplementation. Cases 2 and 3 achieved independence from intravenous magnesium supplementation, whereas case 4 had decreased intravenous magnesium requirements. All the cases demonstrated sustainably improved serum magnesium levels. Withdrawal of SGLT2 inhibitors in case 4 resulted in worsening serum magnesium levels and intravenous magnesium requirements. The extraglycemic benefit of this group of medications not only suggests the need for further studies to better understand the effect of SGLT2 inhibitors on magnesium homeostasis but also supports expanded use in a larger patient population.

Cardiovascular Diseases: Therapeutic Potential of SGLT-2 Inhibitors

Cardiovascular diseases (CVD) are a global health concern, affecting millions of patients worldwide and being the leading cause of global morbidity and mortality, thus creating a major public health concern. Sodium/glucose cotransporter 2 (SGLT2) inhibitors have emerged as a promising class of medications for managing CVD. Initially developed as antihyperglycemic agents for treating type 2 diabetes, these drugs have demonstrated significant cardiovascular benefits beyond glycemic control. In our paper, we discuss the role of empagliflozin, dapagliflozin, canagliflozin, ertugliflozin, and the relatively recently approved bexagliflozin, the class of SGLT-2 inhibitors, as potential therapeutic targets for cardiovascular diseases. All mentioned SGLT-2 inhibitors have demonstrated significant cardiovascular benefits and renal protection in clinical trials, in patients with or without type 2 diabetes. These novel therapeutic approaches aim to develop more effective treatments that improve patient outcomes and reduce the burden of these conditions. However, the major scientific achievements of recent years and the many new discoveries and mechanisms still require careful attention and additional studies.

The risk of all-cause death with dapagliflozin versus placebo: a systematic review and meta-analysis of phase III randomized controlled trials

BACKGROUND

Dapagliflozin has proven cardioprotective and nephroprotective effects. However, the risk of all-cause death with dapagliflozin remains unclear.

RESEARCH DESIGN AND METHODS

We performed a meta-analysis of phase III randomized controlled trials (RCTs) for the risk of all-cause death and safety events with dapagliflozin compared to placebo. PubMed and EMBASE were searched from inception to 20 September 2022.

RESULTS

Five trials were included in the final analysis. Compared with the placebo, dapagliflozin demonstrated an 11.2% reduction in the risk of all-cause death (OR 0.88, 95% CI 0.81-0.94). No statistically significant difference in urinary tract infection (OR: 0.95, 95% CI: 0.78 to 1.17), bone fracture (OR: 1.06, 95% CI: 0.94 to 1.20), and amputation (OR: 1.01, 95% CI: 0.82 to 1.23) was observed between patients treated with dapagliflozin and placebo. Compared with placebo, dapagliflozin was associated with a significant reduction in acute kidney injury (OR: 0.71, 95% CI: 0.60 to 0.83), and increased the risk of genital infection (OR: 8.21, 95% CI: 4.19 to 16.12).

CONCLUSIONS

Dapagliflozin was associated with significantly reduced all-cause death and increased genital infection. Dapagliflozin was safe concerning urinary tract infection, bone fracture, amputation, and acute kidney injury, compared with the placebo.

Effects of Dapagliflozin in Combination with Metoprolol Sustained-Release Tablets on Prognosis and Cardiac Function in Patients with Acute Myocardial Infarction after PCI

Objective

To find the effects of dapagliflozin in combination with metoprolol sustained-release tablets on cardiac function and prognosis in acute myocardial infarction patients after PCI.

Methods

A total of 84 patients with myocardial infarction who experienced PCI from February 2020 to February 2022 were included and allocated into 3 groups: groups A, B, and C (n = 28/per group). Group A was given dapagliflozin combined with metoprolol sustained-release tablets, group B was given dapagliflozin, and group C was given the placebo. Left ventricular end diastolic diameter (EDD), left ventricular ejection fraction (LVEF), and end systolic diameter (ESD) were measured before and after treatment in all groups; myocardial infarction areas were matched among all three groups at 3 months posttreatment. The serum concentrations of interleukin-6 (IL-6), hypersensitive C-reactive protein (hs-CRP), superoxide dismutase (SOD), and malondialdehyde (MDA) were detected in all three groups before and after treatment. The levels of N-terminal probrain natriuretic peptide (NT-pro BNP), lipoprotein (a) (Lp(a)), ischemia-modified albumin (IMA), and secreted frizzled-related protein 5 (SFRP5) were also detected in the serum of all groups. Adverse reactions and cardiovascular adverse events were matched between all groups.

Results

The levels of LVEF in groups A and B were increased after treatment, while the levels of EDD and ESD were decreased. The improvement degree of LVEF and EDD levels in groups A and B was found greater compared to group C (P < 0.05). No significant difference was found in myocardial infarction area among the three groups at 3 months postoperation (P > 0.05). Serum concentrations of MDA, hs-CRP, IL-6, IMA, NT-proBNP, and Lp(a) were found to decrease in all three groups after treatment, while the levels of SOD and SFRP5 were increased. The improvement degree of serum hs-CRP, IL-6, SOD, MDA, IMA, NT-proBNP, Lp(a), and SFRP5 levels was greater in both groups A and B compared to group C. The improvement degree of serum hS-CRP, SOD, MDA, IMA, Nt-probNP, Lp(a), and SFRP5 levels was significantly greater in group A compared to group B (P < 0.05). No adverse effect was observed in all three groups (P > 0.05). Total occurrence of cardiovascular adverse effects such as stent thrombosis, heart failure, ventricular fibrillation, and death was 10.71% in group A, 25.00% in group B, and 53.75% in group C. There was statistical significance in the onset of cardiovascular adverse effects 3 months postoperation among all three groups (P < 0.05).

Conclusion

Dapagliflozin with metoprolol sustained-release tablets can be effective in improving the heart function, inflammatory response, oxidative stress response, and prognosis in patients after PCI.

New Therapeutic Options for Type 2 Diabetes Mellitus and Their Impact Against Ischemic Heart Disease

Type 2 diabetes mellitus (T2DM) greatly increases risk for cardiovascular disease, including ischemic heart disease and myocardial infarction. With the completion of several cardiovascular outcomes trials (CVOTs) for new glucose-lowering therapies, including the sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor (GLP-1R) agonists, we now have strong evidence alluding to the cardioprotective nature of these agents in people with T2DM. These agents have frequently been observed to reduce rates for 3-point major adverse cardiovascular events, which encompass death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. Herein we will provide an overview on whether reductions in nonfatal myocardial infarction and ischemic heart disease status are a key component of the improved cardiovascular outcomes in people with T2DM treated with either SGLT2 inhibitors or GLP-1R agonists. Observations from preclinical studies will be compared to their clinical counterparts, while being further interrogated to define potential mechanisms that may account for SGLT2 inhibitor or GLP-1R agonist-induced cardioprotection against ischemic heart disease. A better understanding of the role these agents have in impacting the progression of ischemic heart disease in individuals with T2DM will have a substantial impact in our management of this patient population.

Empagliflozin in the treatment of heart failure and type 2 diabetes mellitus: Evidence from several large clinical trials

Heart failure coexists with type 2 diabetes mellitus, which seriously affects the clinical treatment and prognosis. At present, the treatment for patients with established heart failure and type 2 diabetes mellitus is usually combined with two treatment strategies for heart failure and type 2 diabetes mellitus. Recently, increasing studies showed that empagliflozin, a sodium-glucose co-transporter-2 inhibitor, has a positive effect on the treatment of patients with established heart failure and type 2 diabetes mellitus. Here, we summarize the latest and current understanding of the management for patients with established heart failure and type 2 diabetes mellitus and further present contemporary treatment options, sodium-glucose co-transporter-2 inhibitor, for these particular populations.
