Review on sodium-glucose cotransporter 2 inhibitor (SGLT2i) in diabetes mellitus and heart failure

Endothelial Senescence in Neurological Diseases

Endothelial cells, which are highly dynamic cells essential to the vascular network, play an indispensable role in maintaining the normal function of the body. Several lines of evidence indicate that the phenotype associated with senescent endothelial cells causes or promotes some neurological disorders. In this review, we first discuss the phenotypic changes associated with endothelial cell senescence; subsequently, we provide an overview of the molecular mechanisms of endothelial cell senescence and its relationship with neurological disorders. For refractory neurological diseases such as stroke and atherosclerosis, we intend to provide some valid clues and new directions for clinical treatment options.

Practical Recommendations for the Use of Angiotensin Receptor-Neprilysin Inhibitors (ARNI) in Heart Failure: Insights from Indian Cardiologists

Heart failure is a significant public health concern characterized by notable rates of morbidity and mortality. Despite the presence of guideline-directed medical therapy (GDMT), its utilization remains inadequate. This practical recommendation paper focuses on the utilization of angiotensin receptor-neprilysin inhibitor (ARNI) as a pivotal treatment for heart failure with reduced ejection fraction (HFrEF), heart failure with preserved ejection fraction (HFpEF), and heart failure with improved ejection fraction (HFimpEF). The recommendations presented in this paper have been developed by a group of cardiologists in India who convened six advisory board meetings to discuss the utilization of ARNI in the management of heart failure. The paper emphasizes the importance of accurate biomarkers for diagnosing heart failure, particularly N-terminal pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP), which are commonly used. Additionally, the paper advocates the use of imaging, specifically echocardiography, in diagnosing and monitoring heart failure patients. Moreover, the paper highlights the role of ARNI in heart failure management, with numerous clinical trials that have demonstrated its effectiveness in reducing cardiovascular death or heart failure hospitalization, enhancing quality of life, and diminishing the risk of ventricular arrhythmias. This practical recommendation paper offers valuable insights into the utilization of ARNI in the management of heart failure, aiming to enhance the implementation of GDMT and ultimately alleviate the burden of heart failure on society.

Early Identification and Management of Heart Failure in Patients with Diabetes Mellitus in the United Arab Emirates: A Call to Action

Heart failure (HF) is a common and serious complication of diabetes mellitus (DM) that remains widely under-recognized. Multidisciplinary management protocols for patients with concurrent DM and HF are not widely utilized in the Middle East/Gulf region, particularly in the United Arab Emirates. Since early identification of patients with DM and HF will likely lead to initiation of therapies known to prevent adverse cardiovascular events and subsequently improve patient prognosis, we aim to highlight the importance of early recognition of HF in diabetic patients. We will also describe existing management challenges in the region, especially the lack of multidisciplinary care and emphasize the role of newer anti-diabetic therapies in preventing and treating HF. Most importantly, this call-to-action proposes a collaborative approach to the care of diabetic patients with HF involving primary care physicians, endocrinologists, and cardiologists.

A Systematic Review Exploring the Cardiovascular and Renal Effects of Empagliflozin in Patients With Heart Failure With Reduced Ejection Fraction

The major cause of death in the United States is heart disease. The global burden of illness and mortality from heart failure is substantial. Despite recent innovations in the treatment of heart failure, the prognosis is still poor. To identify, evaluate, and summarize the findings of all relevant studies of a drug that is equally efficacious but rather cost-effective, empagliflozin compared to the other sodium-glucose cotransporter-2 (SGLT2) inhibitors was studied. It is licensed by the Food and Drug Administration (FDA), acts by preventing the reabsorption of glucose from the kidney, and exhibits promising advantages in heart failure. We systematically explored PubMed, PubMed Central (PMC), and Medical Literature Analysis and Retrieval System Online (MEDLINE) for randomized controlled trials (RCTs) and observational studies related to cardiovascular and renal outcomes of empagliflozin in patients with heart failure with reduced ejection fraction (HFrEF). After performing scoping search and search strategy, studies were screened for quality assessment using the Cochrane risk of bias assessment tool. We screened 60 articles by titles, abstract, and exclusion and inclusion criteria, after which eight final randomized controlled trials (RCTs) with 18,659 participants treated with empagliflozin and placebo were used for the systematic review. This systematic review's objective is to investigate and explore the full range of empagliflozin's effects and advantages on cardiac structure, function, and hemodynamics and renal function in patients with heart failure with reduced ejection fraction (EF) in order to better understand the drug's effects and related mechanisms.

Application of Angiotensin Receptor–Neprilysin Inhibitor in Chronic Kidney Disease Patients: Chinese Expert Consensus

Chronic kidney disease (CKD) is a global public health problem, and cardiovascular disease is the most common cause of death in patients with CKD. The incidence and prevalence of cardiovascular events during the early stages of CKD increases significantly with a decline in renal function. More than 50% of dialysis patients die from cardiovascular disease, including coronary heart disease, heart failure, arrhythmia, and sudden cardiac death. Therefore, developing effective methods to control risk factors and improve prognosis is the primary focus during the diagnosis and treatment of CKD. For example, the SPRINT study demonstrated that CKD drugs are effective in reducing cardiovascular and cerebrovascular events by controlling blood pressure. Uncontrolled blood pressure not only increases the risk of these events but also accelerates the progression of CKD. A co-crystal complex of sacubitril, which is a neprilysin inhibitor, and valsartan, which is an angiotensin receptor blockade, has the potential to be widely used against CKD. Sacubitril inhibits neprilysin, which further reduces the degradation of natriuretic peptides and enhances the beneficial effects of the natriuretic peptide system. In contrast, valsartan alone can block the angiotensin II-1 (AT1) receptor and therefore inhibit the renin–angiotensin–aldosterone system. These two components can act synergistically to relax blood vessels, prevent and reverse cardiovascular remodeling, and promote natriuresis. Recent studies have repeatedly confirmed that the first and so far the only angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril/valsartan can reduce blood pressure more effectively than renin–angiotensin system inhibitors and improve the prognosis of heart failure in patients with CKD. Here, we propose clinical recommendations based on an expert consensus to guide ARNI-based therapeutics and reduce the occurrence of cardiovascular events in patients with CKD.

Risk of hospitalization and death associated with sodium glucose cotransporter-2 inhibitors: A comparison with five other classes of antidiabetic drugs

AIM

We assessed the risk of all-cause hospitalization and all-cause death associated with the use of Sodium Glucose Cotransporter-2 inhibitors (SGLT2i).

METHODS

Population-based propensity scores-matched cohort study of new users of metformin who subsequently initiated SGLT2i compared to those who initiated dipeptidyl peptidase-4 inhibitors (DPP4i) (primary comparison), sulfonylureas, thiazolidinediones, GLP1-Receptors agonists, and insulin, respectively. Alberta (Canada) health administrative data and United Kingdom Clinical Practice Research Datalink (CPRD) data were used to assess the study outcomes. Conditional Cox regressions were performed to assess the risk of each outcome, separately for each dataset and then results were combined using random-effects meta-analysis.

RESULTS

For SGLT2i versus DPP4i, 7531 and 1647 SGLT2i-DPP4i matched pairs were analyzed in Alberta and CPRD data respectively. The mean age of patients was 56 and 57 years, and 39% and 43% were females, respectively in Alberta and CPRD cohorts. Compared with DPP-4-i, SGLT2i use was associated with a significant lower risk of all-cause hospitalization (combined hazard ratio (HR): 0.84, 95% confidence interval (95%CI): 0.75-0.95), and all-cause death (0.56, 0.38-0.83). SGLT2i use was also associated with a significant lower risk of all-cause hospitalization and all-cause death when compared to sulfonylureas (HRs: 0.80, 95%CI: 0.71-0.90 and 0.56, 95%CI: 0.38-0.82, respectively) and insulin (HRs: 0.55, 95%CI: 0.41-0.74, and 0.33, 95%CI: 0.24-0.46, respectively).

CONCLUSIONS

SGLT2i initiation was associated with a decreased risk of all-cause hospitalization and all-cause death when compared to DPP4i, sulfonylureas, and insulin.

Optimal Type 2 Diabetes Mellitus Management and Active Ageing

Type two diabetes mellitus (T2DM) represents a chronic condition with increasing prevalence worldwide among the older population. The T2DM condition increases the risk of micro and macrovascular complications as well as the risk of geriatric syndromes such as falls, fractures and cognitive impairment. The management of T2DM in the older population represents a challenge for the clinician, and a Comprehensive Geriatric Assessment should always be prioritized, in order to tailor the glycated hemoglobin target according to functional and cognitive status comorbidities, life expectancy and type of therapy. According to the most recent guidelines, older adults with T2DM should be categorized into three groups: healthy patients with good functional status, patients with complications and reduced functionality and patients at the end of life; for each group the target for glycemic control is different, also according to the type of treatment drug. The therapeutic approach should always begin with lifestyle changes; after that, several lines of therapy are available, with different mechanisms of action and potential effects other than glucose level reduction. Particular interest is growing in sodium-glucose cotransporter-2 inhibitors, due to their effect on the cardiovascular system. In this review, we evaluate the therapeutic options available for the treatment of older diabetic patients, to ensure a correct treatment approach.

[Impact of dapagliflozin on cardiovascular risk factors. Beyond glycemic control]

Sodium-glucose transport protein 2 (SGLT2) inhibitors are a new class of oral hypoglycemic agents that increase urinary glucose excretion independently of insulin secretion, although an apparently simple mechanism, but with multiple metabolic effects. Dapagliflozin was the first SGLT2 inhibitor marketed in Europe in 2012 for the treatment of patients with type 2 diabetes, and consequently, with the greatest clinical experience. The results of different clinical trials and real-life studies have demonstrated its effectiveness in glycemic control, as they reduce glycosylated hemoglobin, while achieving a decrease in body weight and blood pressure, among others, providing a comprehensive metabolic protection.

The Role of SGLT2 Inhibitors in Vascular Aging

Vascular aging is defined as organic and functional changes in blood vessels, in which decline in autophagy levels, DNA damage, MicroRNA (miRNA), oxidative stress, sirtuin, and apoptosis signal-regulated kinase 1 (ASK1) are integral thereto. With regard to vascular morphology, the increase in arterial stiffness, atherosclerosis, vascular calcification and high amyloid beta levels are closely related to vascular aging. Further closely related thereto, at the cellular level, is the aging of vascular endothelial cells (ECs) and vascular smooth muscle cells (VSMCs). Vascular aging seriously affects the health, economy and life of patients, but can be delayed by SGLT2 inhibitors through the improvement of vascular function. In the present article, a review is conducted of recent domestic and international progress in research on SGLT2 inhibitors,vascular aging and diseases related thereto, thereby providing theoretical support and guidance for further revealing the relationship between SGLT2 inhibitors and diseases related to vascular aging.

Which drug is best for a patient with type 2 diabetes and heart failure?

ABSTRACT

Heart failure is twice as common in men with type 2 diabetes than those without it and is almost five times greater in women with diabetes. Ideally, effective treatment for one condition also will help with the other; certainly, clinicians should not prescribe a medication that will potentially worsen one of the conditions, if avoiding it is at all possible. This article reviews the effects of diabetes medications on heart failure outcomes.

Reducing the need for carbohydrate counting in type 1 diabetes using closed-loop automated insulin delivery (artificial pancreas) and empagliflozin: A randomized, controlled, non-inferiority, crossover pilot trial

AIM

To assess whether adding empagliflozin to closed-loop automated insulin delivery could reduce the need for carbohydrate counting in type 1 diabetes (T1D) without worsening glucose control.

MATERIALS AND METHODS

In an open-label, crossover, non-inferiority trial, 30 adult participants with T1D underwent outpatient automated insulin delivery interventions with three random sequences of prandial insulin strategy days: carbohydrate counting, simple meal announcement (no carbohydrate counting) and no meal announcement. During each sequence of prandial insulin strategies, participants were randomly assigned empagliflozin (25 mg/day) or not, and crossed over to the comparator. Mean glucose for carbohydrate counting without empagliflozin (control) was compared with no meal announcement with empagliflozin (in the primary non-inferiority comparison) and simple meal announcement with empagliflozin (in the conditional primary non-inferiority comparison).

RESULTS

Participants were aged 40 ± 15 years, had 27 ± 15 years diabetes duration and HbA1c of 7.6% ± 0.7% (59 ± 8 mmol/mol). The system with no meal announcement and empagliflozin was not non-inferior (and thus reasonably considered inferior) to the control arm (mean glucose 10.0 ± 1.6 vs. 8.5 ± 1.5 mmol/L; non-inferiority p = .94), while simple meal announcement and empagliflozin was non-inferior (8.5 ± 1.4 mmol/L; non-inferiority p = .003). Use of empagliflozin on the background of automated insulin delivery with carbohydrate counting was associated with lower mean glucose, corresponding to a 14% greater time in the target range. While no ketoacidosis was observed, mean fasting ketones levels were higher on empagliflozin (0.22 ± 0.18 vs. 0.13 ± 0.11 mmol/L; p < .001).

CONCLUSIONS

Empagliflozin added to automated insulin delivery has the potential to eliminate the need for carbohydrate counting and improves glycaemic control in conjunction with carbohydrate counting, but does not allow for the elimination of meal announcement.

Sodium-glucose co-transporter-2 inhibitors in patients with type 2 diabetes mellitus without established cardiovascular disease: Do they have a role in primary prevention?

Most guidelines and cardiovascular outcome trials (CVOTs) focus on secondary prevention of cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM). Patients with T2DM without established CVD (eCVD) also form a critical cohort, for whom primary prevention with timely pharmacological and non-pharmacological interventions can effectively prevent or delay the onset of CVD. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have demonstrated a promising role for primary prevention of CVD in CVOTs and real-world studies. The 2019 American College of Cardiology/American Heart Association guidelines on primary prevention of CVD recommend SGLT2i as one of the add-on treatment options to metformin for adults with T2DM and glycated hemoglobin >7% who have cardiovascular (CV) risk factors. The outcomes with maximal response to SGLT2i use in primary prevention are hospitalization for heart failure and chronic kidney disease. The cardiorenal benefits with SGLT2i are attributed to pleiotropic effects on CV risk factors, and interference with glucose and sodium handling in kidneys, independent of their glycemic benefits. Results therefore support a role for SGLT2i not only in patients with T2DM and eCVD but also in patients with T2DM without eCVD. This review examines the evidence for potential role of SGLT2i for primary prevention of CVD in T2DM.

Empagliflozin Effectively Attenuates Olanzapine-Induced Body Weight Gain in Female Wistar Rats

Atypical antipsychotic drugs are commonly associated with undesirable side effects including body weight gain (BWG) and metabolic deficits. Many pharmacological interventions have been tested in an attempt to minimize or prevent these side effects. Preliminary evidence suggests that antidiabetic drugs may be effective in attenuating antipsychotic-induced BWG. In the current study, we examined the effect of an antidiabetic drug empagliflozin (EMPA) on BWG induced by anatypical antipsychotic drug olanzapine (Ola) in female and male Wistar rats. Rats were divided into six groups based on the dose they received: group 1 (female control), group 2 (female EMPA, 20 mg/kg; IG), group 3 (female Ola, 4 mg/kg; IP), group 4 (female Ola, 4 mg/kg; IP + EMPA, 20 mg/kg; IG), group 5 (male control), and group 6 (male Ola, 4 mg/kg; IP). Ola induced sustained increase in BWG. The subsequent treatment of Group 3 and 4 with EMPA attenuated the Ola-induced BWG in female Wistar rats. In terms of the gender difference between female and male Wistar rats, the male control group 5 gained more weight throughout the study as compared to the female control group 1. Similarly, the male Ola group 6 gained more weight throughout the study as compared to the female Ola group 3. However, Ola did not cause any weight difference between male rats treated with Ola in comparison with male control group, thus showing a significant gender difference regarding body weight between male and female Wistar rats regardless of Ola administration. In addition, the present findings showed that EMPA effectively attenuates the Ola induced BWG in female Wistar rats. These novel findings should help to better understand the underlying molecular and behavioral mechanisms contributing to the observed increase in body weight after treatment with Ola and other atypical antipsychotic drugs across male and female rats.

Standardizing the Effective Correlated Dosage of Olanzapine and Empagliflozin in Female Wistar Rats

AIM

The primary aim of this study was to standardize the correlated effective dosage of the antidiabetic drug empagliflozin (EMPA) and the antipsychotic drug olanzapine (Ola).

BACKGROUND

Atypical antipsychotics are associated with BWG and metabolic disturbances for which many approaches have been used to minimize these issues, including antidiabetic drugs. The antidiabetic drugs have been quite effective in reversing BWG induced by the administration of antipsychotic drugs in patients who have psychosis, schizophrenia and bipolar disorder.

OBJECTIVE

The objective of this study was to standardize the correlated effective dosage of EMPA and Ola.

METHODS

The study was carried out for 28 days to represent the chronic effect of Ola on female Wistar rats. Rats were divided into three groups based on the dose they received: control (vehicle), Ola-4 and Ola-8 (4 and 8 mg/kg/OD, respectively), and EMPA-10 and EMPA-20 (10 and 20 mg/kg/OD, respectively).

RESULTS

Both doses of Ola produced a significant increase in the percentage of BWG, however, Ola-4 produced a higher BWG. Also, both the doses of EMPA were able to reverse the effect of Ola-induced BWG; however, EMPA-20 produced a higher reversal in BWG and normalized the rat's body weight.

CONCLUSION

We conclude that Ola-4 and EMPA-20 were the most effective dosage for experimental purposes in female Wistar rats. The findings of this study standardized the effective correlated dosage of olanzapine and empagliflozin in female Wistar rats that will help understand the underlying molecular and behavioral mechanisms.

A Clinical Study on the Association of Sodium-Glucose Cotransporter 2 Inhibitors and Acute Kidney Injury Among Diabetic Chinese Population

PURPOSE

To investigate the association of Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitors and acute kidney injury in comparison to other classes of drugs.

PATIENTS AND METHODS

A total of 4966 diabetes mellitus patients were investigated for developing Acute Kidney Injury (AKI) who were under prescription with the following class of drugs viz. SGLT2 Inhibitors, Dipeptidyl peptidase-4 (DDP4) inhibitors, Nonsteroidal anti-inflammatory drugs (NSAIDs), first-line drugs and anti-biotics. The primary outcome was based on the hospital encounter and Kidney Disease Improving Global Outcome (KDIGO) threshold values were used to assess the serum creatinine concentration. The secondary outcome was assessed based on the concentration level of serum creatinine after 90 days of hospital admission and evaluation of the KDIGO threshold values.

RESULTS

The study observed that the risk of causing AKI for SGLT2 inhibitors was 5.59% which was comparatively low compared to other class of the investigated drugs (DPP4 inhibitors = 6.47%, antibiotics = 6.30%, first-line drugs = 6.82% and NSAIDs = 10.65%). The multivariate analysis observed that ibuprofen, celecoxib, indomethacin, insulin, cephalexin, and alogliptin were mostly associated with an increased rate of AKI. SGLT2 inhibitors have the lowest risk for developing AKI compared to other drugs and control.

CONCLUSION

AKI incidence is relatively low after initiation of SLGT2 inhibitors and concludes that regulatory warnings from certain health agencies about its risk for AKI on prescription are unwarranted.

Drug-drug interactions when treating HIV-related metabolic disorders

Introduction: Drug-drug interactions (DDI) between antiretroviral drugs and drugs for the treatment of metabolic disturbances in people living with human immunodeficiency virus (HIV) (PLWH) have represented a problem of paramount importance in the recent times. The problem has been mainly driven by sharing common metabolizing pathways. This problem has classically been worsened by the frequent use of pharmacokinetic boosters to enhance protease inhibitors and some integrase inhibitors plasma levels. Areas covered: This article focuses on the interactions between antiretroviral drugs and those drugs used to treat metabolic disturbances which frequently appear in PLWH. These include dyslipidemia, diabetes mellitus, hyperuricemia, and finally, drugs for the treatment of overweight and clinical obesity. References from PubMed, Embase, or Web of Science, among others, were reviewed. Expert opinion: The advent of safer drugs, in terms of DDI, in the antiretroviral and the metabolic field,such as non-boosted antiretrovirals and drugs with divergent metabolizing paths. Besides, learning by the caregivers on how to decrease and manage DDI, together with the extensive use of online updated DDI databases, has undoubtedly minimized the problem. The foreseeable increase in the burden of HIV-associated comorbidities and their associated treatments anticipates further complexities in the management of DDI in PLWH.
