Use of Sodium-Glucose Cotransporter 2 Inhibitors in Hospitalized Patients.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have noted benefits in the treatment of type 2 diabetes, cardiovascular disease, heart failure, and chronic kidney disease. Despite these benefits, the adoption of SGLT2i in clinical practice has been slow. Early initiation of SGLT2i during hospitalization has been proposed to address this gap for 2 important reasons: 1) it provides early clinical benefit in multiple disease states; and 2) hospitalization presents an opportunity for medication optimization and patient education, thereby overcoming clinical inertia. Challenges in SGLT2i adoption necessitate innovative strategies for integration into clinical practice. Ongoing trials and novel care delivery models are anticipated to further elucidate effective strategies for SGLT2i implementation and adherence. This review synthesizes the accrued evidence of SGLT2i across various chronic diseases. It emphasizes the rationale for early in-hospital initiation and discusses barriers and potential solutions for widespread implementation of SGLT2i in hospitalized patients.

Comparing clinical outcomes in patients with type 2 diabetes mellitus after ischaemic stroke: Sodium-glucose cotransporter 2 inhibitors users versus non-users. A propensity score matching National Cohort Study.

AIM: This nationwide cohort study evaluated the impact of sodium-glucose co-transporter-2 inhibitors (SGLT2i) on patients with type 2 diabetes mellitus (T2DM) after ischaemic stroke (IS), aiming to compare clinical outcomes between SGLT2i-treated patients and those not receiving SGLT2i. MATERIALS AND METHODS: Utilizing Taiwan's National Health Insurance Research Database, we identified 707 patients with T2DM treated with SGLT2i and 27 514 patients not treated with SGLT2i after an IS, respectively, from 1 May 2016 to 31 December 2019. Propensity score matching was applied to balance baseline characteristics. The follow-up period extended from the index date (3 months after the index acute IS) until the independent occurrence of the study outcomes, 6 months after discontinuation of the index drug, or the end of the study period (31 December 2020), whichever came first. RESULTS: After propensity score matching, compared with the non-SGLT2i group (n = 2813), the SGLT2i group (n = 707) exhibited significantly lower recurrent IS rates (3.605% per year vs. 5.897% per year; hazard ratio: 0.55; 95% confidence interval: 0.34-0.88; p = 0.0131) and a significant reduction in all-cause mortality (5.396% per year vs. 7.489% per year; hazard ratio: 0.58; 95% confidence interval: 0.39-0.85; p = 0.0058). No significant differences were observed in the rates of acute myocardial infarction, cardiovascular death, heart failure hospitalization, or lower limb amputation. CONCLUSIONS: Our findings indicate significantly lower risks of recurrent IS and all-cause mortality among patients with T2DM receiving SGLT2i treatment. Further studies are required to validate these results and investigate the underlying mechanisms behind the observed effects.

Glucagon-like peptide-1 receptor agonists and risk of sight-threatening retinopathy in Taiwanese population: A propensity based cohort study.

AIMS: To compare the risk of vision-threatening retinopathy between glucagon-like peptide-1 receptor agonists (GLP-1 RA) use and no use in patients with type 2 diabetes. METHODS: Using propensity score matching, we identified 27,506 pairs of GLP-1 RA users and non-users, 3904 pairs of GLP-1 RA and dipeptidyl peptidase-4 inhibitors (DPP-4i) users, 10,985 pairs of GLP-1 RA and sodium-glucose cotransporter-2 inhibitors (SGLT2i) users, 2542 pairs of GLP-1 RA and sulfonylurea, respectively, from Taiwan's National Health Insurance Research Database from January 1, 2009 to December 31, 2018. We used Cox proportional hazards models to compare the risk of vision-threatening retinopathy between GLP-1 RA use and other matched groups. RESULTS: In the matched cohorts, the time-varying exposure analysis showed that GLP-1 RA use was not associated with an increased risk of vision-threatening retinopathy compared to GLP-1 RA non-use (aHR 0.96, 95 % CI 0.89-1.03). New-user and active-comparator analyses showed that GLP-1 RA was associated with a significantly lower risk of vision-threatening retinopathy than DPP-4i (aHR 0.8, 95 % CI 0.66-0.97) but had no significant association with this risk compared to SGLT2i (aHR 1.09, 95 % CI 0.96-1.24) or sulfonylureas (aHR 0.79, 95 % CI 0.49-1.06). CONCLUSIONS: This nationwide cohort study showed that GLP-1 RA use was not associated with an increased risk of vision-threatening retinopathy compared to non- GLP-1 RA use, and GLP-1 RA could significantly lower the risk of vision-threatening retinopathy than DPP-4i.

Prescription Patterns for Sodium-Glucose Cotransporter 2 Inhibitors in U.S. Health Systems.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce heart failure (HF) hospitalizations, recurrent cardiovascular events, and chronic kidney disease (CKD) progression, and thus constitute a Class 1a recommendation in people with diabetes and atherosclerotic cardiovascular disease, HF, or CKD and in people with severe albuminuria or HF, regardless of diabetes status. OBJECTIVES: The purpose of this study was to comprehensibly characterize the rate of SGLT2 inhibitor prescriptions among people with a Class 1a recommendation for SGLT2 inhibitor use. METHODS: Among 3,189,827 adults from 28 U.S. health systems within Optum Labs Data Warehouse between April 1, 2022, and March 31, 2023, we assessed SGLT2 inhibitor prescription rates, stratified by presence of diabetes and Class 1a recommendation. RESULTS: Among 716,387 adults with diabetes, 63.4% had a Class 1a recommendation for SGLT2 inhibitor therapy. There was little difference by Class 1a recommendation status (present: 11.9%; 95% CI: 11.9%-12.0% vs absent: 11.4%; 95% CI: 11.3%-11.6%; standardized mean difference: 1.3%). Among 2,473,440 adults without diabetes, 6.2% had a Class 1a recommendation for SGLT2 inhibitor therapy, and 3.1% (3.0%-3.2%) of those received a prescription. Internists/family practitioners initiated SGLT2 inhibitor prescriptions most commonly among people with diabetes, whereas specialists initiated SGLT2 inhibitor prescriptions most commonly among people without diabetes. No health system had >25% SGLT2 inhibitor prescription rate among people with a Class 1a recommendation. Health systems with higher proportions of patients with commercial insurance and lower proportions with Medicare had higher SGLT2 inhibitor prescription rates. CONCLUSIONS: In this analysis of U.S. data from 2022 to 2023, SGLT2 inhibitor prescription among people with a Class 1a recommendation is low. Interventions are needed to increase uptake of guideline-recommended SGLT2 inhibitor use.

Kidney and Cardiovascular Effectiveness of SGLT2 Inhibitors vs GLP-1 Receptor Agonists in Type 2 Diabetes.

BACKGROUND: Emerging data suggest that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improve kidney outcomes for people with type 2 diabetes (T2D). Direct comparisons of the kidney and cardiovascular effectiveness of GLP-1 RA with sodium-glucose cotransporter 2 inhibitors (SGLT2i), a first-line therapy for this population, are needed. OBJECTIVES: The authors compared kidney and cardiovascular outcomes for new users of SGLT2i and GLP-1 RAs with T2D. METHODS: Using propensity score overlap weighting, we analyzed electronic health record data from 20 U.S. health systems contributing to PCORnet between 2015 and 2020. The primary kidney outcome was a composite of sustained 40% estimated glomerular filtration rate (eGFR) decline, incident end-stage kidney disease, or all-cause mortality over 2 years or until censoring. In addition, we examined cardiovascular and safety outcomes. RESULTS: The weighted study cohort included 35,004 SGLT2i and 47,268 GLP-1 RA initiators. Over a median of 1.2 years, the primary outcome did not differ between treatments (HR: 0.91; 95% CI: 0.81-1.02), although SGLT2i were associated with a lower risk of 40% eGFR decline (HR: 0.77; 95% CI: 0.65-0.91). Risks of mortality (HR: 1.08; 95% CI: 0.92-1.27), a composite of stroke, myocardial infarction, or death (HR: 1.03; 95% CI: 0.93-1.14), and heart failure hospitalization (HR: 0.95; 95% CI: 0.80-1.13) did not differ. Genital mycotic infections were more common for SGLT2i initiators, but other safety outcomes did not differ. The results were similar regardless of chronic kidney disease status. CONCLUSIONS: SGLT2i and GLP-1 RAs led to similar kidney and cardiovascular outcomes in people with T2D, though SGLT2i initiation was associated with a lower risk of 40% eGFR decline.

Trends in utilization patterns of newer glucose-lowering drugs in US adults with type 2 diabetes and a history of coronary heart disease or heart failure: 2005-2019.

BACKGROUND: The newer glucose-lowering drugs (GLDs), including Glucagon-like peptide-1 receptor agonists (GLP-1RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i), have demonstrated superior cardio- and renal protective benefits compared to older GLDs in individuals with type 2 diabetes (T2D) at high risk for cardiovascular disease (CVD). OBJECTIVE: This study examined the trends of the newer GLDs use in people with T2D who had a history of coronary heart disease or heart failure in the United States. METHOD: We used 2005-2019 data from the Medical Expenditure Panel Survey (MEPS). Individuals with self-reported diabetes and CVD history were identified. RESULTS: There was a steady increase in the use of GLP-1RA only from 2008 (3 %) to 2019 (21 %) and SGLT2i only from 2014 (5 %) to 2019 (12 %). Individuals with dual use of both newer GLD classes increased from 0.62 % in 2015 to 6 % in 2019. The overall uptake of these two newer drugs in 2019 was less than 40 %. In other words, 60 % of individuals who can substantially benefit from these newer treatments did not use the treatments. CONCLUSION: The use of GLP-1RA and SGLT2i among individuals with T2D and a history of CVD was low and varied by insurance type. Policy-level interventions are needed to improve the use of these newer treatments further. SUMMARY: We examined how newer glucose-lowering drugs are used among individuals with type 2 diabetes and at high risk for coronary heart disease or heart failure in the US. We found that 60 % of individuals who can substantially benefit from these newer treatments did not use the treatments due to the variation of insurance type.

Patient-important outcomes in type 2 diabetes: The paradigm of the sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists.

The newfound knowledge in type 2 diabetes (T2D) during the past decade for the sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) is wealthy in favorable results for key patient-important outcomes including morbidity, mortality and health-related quality of life (HRQoL). The SGLT-2i and GLP-1RA offer cardiovascular and renal protection beyond their glucose lowering effect, reduce body weight and hypoglycemia and improve diabetes-related distress, physical function and HRQoL. Along with the fixed-ratio combinations of basal insulin/GLP-1RA, they make feasible a regimen simplification and de-escalation from high dose and multiple injections of insulin reducing treatment burden. Besides cardiorenal risk reduction, the SGLT-2i and GLP-1RA reduce the incidence of depression, cognitive decline, respiratory disease, gout, arrhythmias and other co-occurring conditions of T2D, namely multimorbidity, which frequently complicates T2D and adversely affects HRQoL. The alleviation of multimorbidity by the pleiotropic effects of the SGLT-2i and GLP-1RA, could improve patients' HRQoL. The use of the SGLT-2i and GLP-1RA should be increased within a shared decision-making in which they are reframed as cardiorenal risk-reducing medications with the potential to lower blood glucose. By improving outcomes that patients may highly perceive and value, the SGLT-2i and GLP-1RA may facilitate the contemporary person-centered management of T2D.

SGLT-2 inhibitors and nephrolithiasis risk: a meta-analysis.

BACKGROUND AND AIM: Sodium-glucose cotransporter (SGLT)-2 inhibitors are novel anti-diabetic medications with potential beneficial effects on cardiovascular and renal outcomes, metabolic parameters, and body weight. In addition to the beneficial effects on renal functions, including estimated glomerular filtration rate and reduction in proteinuria, recent studies have investigated the potential role of SGLT-2 inhibitor therapy on nephrolithiasis development. Nephrolithiasis, a condition affecting almost 10% of the general population at least once during a lifetime, is a common disorder with considerable risk for acute and chronic kidney injury and relatively few effective therapeutic options. MATERIALS AND METHODS: We have performed a literature search through multiple databases, including PubMed, Ovid/Medline, Web of Science, Scopus, and Cochrane Library. We have followed the systematic review and meta-analysis guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses.We have included a total of 11 635 698 patients who experienced nephrolithiasis from six clinical trials to conduct this meta-analysis study. In the pooled analysis, nephrolithiasis occurred in 1,27% of patients from the SGLT2i group (n = 739 197), compared to 1,56% of patients (n = 10 896 501) from the control arm (active control, placebo or no therapy). RESULTS: We have included a total of 11 635 698 participants who experienced nephrolithiasis from a total of six clinical studies with nephrolithiasis rates of 1,27% in the SGLT2i group (n = 739 197), compared to 1,56% in the control arm (n = 10 896 501). SGLT-2 inhibitor therapy has been associated with a lower risk for nephrolithiasis compared to placebo (OR 0.61, 95% CI, 0.53-0.70, p < 0.00001) or active therapy such as glucagon-like peptide 1 and dipeptidyl peptidase-IV inhibitors (OR 0.66, 95% CI, 0.47-0.93, p = 0.02). CONCLUSION: We have demonstrated a lower risk of nephrolithiasis risk with SGLT-2 inhibitor therapy compared to placebo or active control. Potential underlying mechanisms include osmotic diuresis leading to a reduction in the concentration of lithogenic substances, anti-inflammatory and anti-fibrotic effects, and an increase in urine pH. There is a clear need for future large-scale randomized clinical trials evaluating such associations for better understanding.

Sodium-glucose cotransporter 2 inhibitors and renin-angiotensin-aldosterone system, possible cellular interactions and benefits.

Sodium glucose cotransporter 2 inhibitors (SGLT2is) are a newly developed class of anti-diabetics which exert potent hypoglycemic effects in the diabetic milieu. However, the evidence suggests that they also have extra-glycemic effects. The renin-angiotensin-aldosterone system (RAAS) is a hormonal system widely distributed in the body that is important for water and electrolyte homeostasis as well as renal and cardiovascular function. Therefore, modulating RAAS activity is a main goal in patients, notably diabetic patients, which are at higher risk of complications involving these organ systems. Some studies have suggested that SGLT2is have modulatory effects on RAAS activity in addition to their hypoglycemic effects and, thus, these drugs can be considered as promising therapeutic agents for renal and cardiovascular disorders. However, the exact molecular interactions between SGLT2 inhibition and RAAS activity are not clearly understood. Therefore, in the current study we surveyed the literature for possible molecular mechanisms by which SGLT2is modulate RAAS activity.

Dapagliflozin Use in Children with Advanced Heart Failure Undergoing Heart Transplantation: A Matched Case-Control Study.

Dapagliflozin has been associated with euglycemic ketoacidosis in adults with diabetes contributing to poor outcomes when continued prior to surgery. It is unknown if preoperative use of dapagliflozin may lead to adverse events (AE) in nondiabetic children with advanced heart failure (HF) undergoing heart transplantation (HTx). We performed a single-center, matched case-control analysis of nondiabetic primary pediatric HTx recipients < 21 years-old who underwent HTx and followed through postoperative day (POD) 3. Cases who received dapagliflozin leading up to HTx (n = 22) were matched by age and cardiac diagnosis to two historical controls who did not receive dapagliflozin (n = 44). Median age at HTx was 13.8 years (range 0.36-20.7) and 48% were female. Cardiac diagnoses included cardiomyopathy (45%), Fontan failure (41%), and single ventricle status post stage I palliation (14%). Cases received median dapagliflozin dose of 0.17 mg/kg once daily; therapy was stopped one day prior to HTx. There were no significant differences in blood glucose nadirs, arterial blood gas indices including nadirs of pH, bicarbonate, or peaks of arterial blood lactic acid POD0-3. Vasopressor, inotrope, and insulin infusion usage were not different. No patients were treated for severe hypoglycemia, euglycemic ketoacidosis, or urinary tract infections. There were no deaths. Length of stay in ICU and time from HTx to hospital discharge did not differ between cohorts. Use of dapagliflozin in children with advanced HF until HTx is not associated with AE in the immediate postoperative period nor increased length of hospitalization post-HTx. Potential cardiovascular benefits of dapagliflozin in patients awaiting HTx should be prioritized.

Sodium-Glucose Cotransporter-2 Inhibitors in Patients With Acute Coronary Syndrome: A Modern Cinderella?

PURPOSE: Atherosclerotic cardiovascular disease remains a prominent global cause of mortality, with coronary artery disease representing its most prevalent manifestation. Recently, a novel class of antidiabetic medication, namely sodium-glucose cotransporter-2 (SGLT2) inhibitors, has been reported to have remarkable cardiorenal advantages for individuals with type 2 diabetes mellitus (DM), and they may reduce cardiorenal risk even in individuals without pre-existing DM. Currently, there is no evidence regarding the safety and efficacy of these drugs in acute coronary syndrome (ACS), regardless of diabetes status. This review aims to comprehensively present the available preclinical and clinical evidence regarding the potential role of SGLT2 inhibitors in the context of ACS, as adjuncts to standard-of-care treatment for this patient population, while also discussing potential short- and long-term cardiovascular benefits. METHODS: A literature search was performed through MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials, and Scopus until February 26, 2024. Eligible were preclinical and clinical studies, comprising randomized controlled trials (RCTs), real-world studies, and meta-analyses. FINDINGS: Evidence from preclinical models indicates that the use of SGLT2 inhibitors is associated with a blunted ischemia-reperfusion injury and decreased myocardial infarct size, particularly after prior treatment. Although RCTs and real-world data hint at a potential benefit in acute ischemic settings, showing improvements in left ventricular systolic and diastolic function, decongestion, and various cardiometabolic parameters such as glycemia,body weight, and blood pressure, the recently published DAPA-MI (Dapagliflozin in Myocardial Infarction without Diabetes or Heart Failure) trial did not establish a clear advantage regarding surrogate cardiovascular end points of interest. SGLT2 inhibitors appear to provide a benefit in reducing contrast-induced acute kidney injury events in patients with ACS undergoing percutaneous coronary intervention. However, data on other safety concerns, such as treatment discontinuation because of hypotension, hypovolemia, or ketoacidosis, are currently limited. IMPLICATIONS: Despite the well-established cardiovascular benefits observed in the general population with type 2 DM and, more recently, in other patient groups irrespective of diabetes status, existing evidence does not support the use of SGLT2 inhibitors in the context of ACS. Definitive answers to this intriguing research question, which could potentially expand the therapeutic indications of this novel drug class, require large-scale, well-designed RCTs.

Relationship between sodium-glucose cotransporter 2 inhibitors and atrial fibrillation recurrence after pulmonary vein isolation in patients with type 2 diabetes and persistent atrial fibrillation.

BACKGROUND: The impact of sodium-glucose cotransporter 2 (SGLT2) inhibitors on the postoperative recurrence of atrial fibrillation (AF) in patients with persistent AF undergoing an initial radiofrequency ablation is not yet established. The objective of this study is to assess the impact of SGLT2 inhibitors on the recurrence of AF after radiofrequency ablation in patients with type 2 diabetes complicated persistent AF. METHODS: A total of 182 patients with type 2 diabetes and persistent AF, who underwent their first radiofrequency ablation for AF at our center, were enrolled and divided into two groups: the SGLT2 inhibitor group and the non-SGLT2 inhibitor group. The main outcome of the follow-up was the postoperative recurrence of AF. RESULTS: A total of 49 participants experienced AF recurrence. The use of SGLT2 inhibitors in patients with type 2 diabetes who underwent AF ablation was associated with a significantly lower risk of AF recurrence (adjusted hazard ratio: 0.65; 95% confidence interval: 0.28-0.83; p < .01). CONCLUSIONS: The use of SGLT2 inhibitors is associated with a decreased risk of arrhythmia recurrence after AF ablation in patients with type 2 diabetes complicated with persistent AF.

Sodium-glucose cotransporter-2 inhibitors protect tissues via cellular and mitochondrial pathways: Experimental and clinical evidence.

Mitochondrial dysfunction is a key driver of cardiovascular disease (CVD) in metabolic syndrome and diabetes. This dysfunction promotes the production of reactive oxygen species (ROS), which cause oxidative stress and inflammation. Angiotensin II, the main mediator of the renin-angiotensin-aldosterone system, also contributes to CVD by promoting ROS production. Reduced activity of sirtuins (SIRTs), a family of proteins that regulate cellular metabolism, also worsens oxidative stress. Reduction of energy production by mitochondria is a common feature of all metabolic disorders. High SIRT levels and 5' adenosine monophosphate-activated protein kinase signaling stimulate hypoxia-inducible factor 1 beta, which promotes ketosis. Ketosis, in turn, increases autophagy and mitophagy, processes that clear cells of debris and protect against damage. Sodium-glucose cotransporter-2 inhibitors (SGLT2i), a class of drugs used to treat type 2 diabetes, have a beneficial effect on these mechanisms. Randomized clinical trials have shown that SGLT2i improves cardiac function and reduces the rate of cardiovascular and renal events. SGLT2i also increase mitochondrial efficiency, reduce oxidative stress and inflammation, and strengthen tissues. These findings suggest that SGLT2i hold great potential for the treatment of CVD. Furthermore, they are proposed as anti-aging drugs; however, rigorous research is needed to validate these preliminary findings.

Glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, anti-diabetic drugs in heart failure and cognitive impairment: potential mechanisms of the protective effects.

Heart failure and cognitive impairment emerge as public health problems that need to be addressed due to the aging global population. The conditions that often coexist are strongly related to advancing age and multimorbidity. Epidemiological evidence indicates that cardiovascular disease and neurodegenerative processes shares similar aspects, in term of prevalence, age distribution, and mortality. Type 2 diabetes increasingly represents a risk factor associated not only to cardiometabolic pathologies but also to neurological conditions. The pathophysiological features of type 2 diabetes and its metabolic complications (hyperglycemia, hyperinsulinemia, and insulin resistance) play a crucial role in the development and progression of both heart failure and cognitive dysfunction. This connection has opened to a potential new strategy, in which new classes of anti-diabetic medications, such as glucagon-like peptide-1 receptor (GLP-1R) agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors, are able to reduce the overall risk of cardiovascular events and neuronal damage, showing additional protective effects beyond glycemic control. The pleiotropic effects of GLP-1R agonists and SGLT2 inhibitors have been extensively investigated. They exert direct and indirect cardioprotective and neuroprotective actions, by reducing inflammation, oxidative stress, ions overload, and restoring insulin signaling. Nonetheless, the specificity of pathways and their contribution has not been fully elucidated, and this underlines the urgency for more comprehensive research.

Skin-Related Adverse Reactions Induced by Oral Antidiabetic Drugs-A Review of Literature and Case Reports.

Type 2 diabetes (T2DM) is a chronic metabolic disease with a steadily increasing prevalence worldwide. Diabetes affects the function of many organs, including the skin. Pharmacotherapy for T2DM is mainly based on oral hypoglycemic drugs. The therapeutic strategy is chosen taking into account the individual patient's characteristics, among other comorbidities. Antidiabetic drugs can induce cutaneous adverse reactions (CADRs) ranging in severity from mild erythema to serious disorders such as DRESS or Stevens-Johnson syndrome. CADRs can result from hypersensitivity to the drug but can also be related to the mechanism of action of the drug or cross-reactivity with drugs of similar structure. This paper reviews CADRs induced by oral antidiabetic drugs, considering their dermatological manifestations and possible pathomechanisms. Particular attention was paid to specific dermatological conditions such as dipeptidylpeptidase 4 inhibitor-associated bullous pemphigoid or Fournier's gangrene associated with sodium-glucose cotransporter 2 inhibitor therapy. Knowledge of the dermatological manifestations of CADRs is important in clinical practice. Recognition of a skin lesion resulting from an adverse drug reaction allows for appropriate management, which in this case is primarily related to drug discontinuation. This is particularly important in the treatment of T2DM since this disease has a high prevalence in the elderly, who are at higher risk of adverse drug reactions.

Sodium-Glucose Cotransporter Inhibitors: Cellular Mechanisms Involved in the Lipid Metabolism and the Treatment of Chronic Kidney Disease Associated with Metabolic Syndrome.

Metabolic syndrome (MetS) is a multifactorial condition that significantly increases the risk of cardiovascular disease and chronic kidney disease (CKD). Recent studies have emphasized the role of lipid dysregulation in activating cellular mechanisms that contribute to CKD progression in the context of MetS. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have demonstrated efficacy in improving various components of MetS, including obesity, dyslipidemia, and insulin resistance. While SGLT2i have shown cardioprotective benefits, the underlying cellular mechanisms in MetS and CKD remain poorly studied. Therefore, this review aims to elucidate the cellular mechanisms by which SGLT2i modulate lipid metabolism and their impact on insulin resistance, mitochondrial dysfunction, oxidative stress, and CKD progression. We also explore the potential benefits of combining SGLT2i with other antidiabetic drugs. By examining the beneficial effects, molecular targets, and cytoprotective mechanisms of both natural and synthetic SGLT2i, this review provides a comprehensive understanding of their therapeutic potential in managing MetS-induced CKD. The information presented here highlights the significance of SGLT2i in addressing the complex interplay between metabolic dysregulation, lipid metabolism dysfunction, and renal impairment, offering clinicians and researchers a valuable resource for developing improved treatment strategies and personalized approaches for patients with MetS and CKD.

Case report: A case of Rabson-Mendenhall syndrome: long-term follow-up and therapeutic management with empagliflozin.

Background: Rabson-Mendenhall syndrome (RMS), a rare disorder characterized by severe insulin resistance due to biallelic loss-of-function variants of the insulin receptor gene (INSR), presents therapeutic challenges (OMIM: 262190). This case study explores the efficacy of adjunctive therapy with sodium-glucose cotransporter 2 inhibitors (SGLT2is) in the management of RMS in an 11-year-old male patient with compound heterozygous pathogenic variants of INSR. Methods: Despite initial efforts to regulate glycemia with insulin therapy followed by metformin treatment, achieving stable glycemic control presented a critical challenge, characterized by persistent hyperinsulinism and variable fluctuations in glucose levels. Upon the addition of empagliflozin to metformin, notable improvements in glycated hemoglobin (HbA1c) and time in range (TIR) were observed over a 10-month period. Results: After 10 months of treatment, empagliflozin therapy led to a clinically meaningful reduction in HbA1c levels, decreasing from 8.5% to 7.1%, along with an improvement in TIR from 47% to 74%. Furthermore, regular monitoring effectively averted normoglycemic ketoacidosis, a rare complication associated with SGLT2 inhibitor therapy. Conclusion: This case highlights the potential of SGLT2i as adjunctive therapy in RMS management, particularly in stabilizing glycemic variability. However, further research is warranted to elucidate the long-term efficacy and safety of this therapeutic approach in RMS and similar insulin resistance syndromes.

Adjunctive therapy with an oral H2S donor provides additional therapeutic benefit beyond SGLT2 inhibition in cardiometabolic heart failure with preserved ejection fraction.

BACKGROUND AND PURPOSE: Sodium glucose cotransporter 2 inhibitors (SGLT2i) have emerged as a potent therapy for heart failure with preserved ejection fraction (HFpEF). Hydrogen sulphide (H2S), a well-studied cardioprotective agent, could be beneficial in HFpEF. SGLT2i monotherapy and combination therapy involving an SGLT2i and H2S donor in two preclinical models of cardiometabolic HFpEF was investigated. EXPERIMENTAL APPROACH: Nine-week-old C57BL/6N mice received L-NAME and a 60% high fat diet for five weeks. Mice were then randomized to either control, SGLT2i monotherapy or SGLT2i and H2S donor, SG1002, for five additional weeks. Ten-week-old ZSF1 obese rats were randomized to control, SGLT2i or SGLT2i and SG1002 for 8 weeks. SG1002 monotherapy was investigated in additional animals. Cardiac function (echocardiography and haemodynamics), exercise capacity, glucose handling and multiorgan pathology were monitored during experimental protocols. KEY RESULTS: SGLT2i treatment improved E/e' ratio and treadmill exercise in both models. Combination therapy afforded increases in cardiovascular sulphur bioavailability that coincided with improved left end-diastolic function (E/e' ratio), exercise capacity, metabolic state, cardiorenal fibrosis, and hepatic steatosis. Follow-up studies with SG1002 monotherapy revealed improvements in diastolic function, exercise capacity and multiorgan histopathology. CONCLUSIONS AND IMPLICATIONS: SGLT2i monotherapy remediated pathological complications exhibited by two well-established HFpEF models. Adjunctive H2S therapy resulted in further improvements of cardiometabolic perturbations beyond SGLT2i monotherapy. Follow-up SG1002 monotherapy studies inferred an improved phenotype with combination therapy beyond either monotherapy. These data demonstrate the differing effects of SGLT2i and H2S therapy while also revealing the superior efficacy of the combination therapy in cardiometabolic HFpEF.
