Empagliflozin as add-on to metformin plus sulfonylurea in patients with type 2 diabetes: a 24-week, randomized, double-blind, placebo-controlled trial

SGLT2-inhibition increases total, LDL, and HDL cholesterol and lowers triglycerides: Meta-analyses of 60 randomized trials, overall and by dose, ethnicity, and drug type

BACKGROUND AND AIMS

Sodium glucose co-transporter 2 (SGLT2)-inhibitors were developed as glucose-lowering drugs. Surprisingly, SGLT2-inhibitors also reduced risk of cardiovascular disease. The impact of SGLT2-inhibitors on lipids and lipoproteins is unclear, but an effect might contribute to the observed lower cardiovascular risk. We conducted a meta-analysis to examine this, overall and by dose, ethnicity, and drug type.

METHODS

PubMed, EMBASE and Web of Science were searched for randomized controlled trials examining all available SGLT2-inhibitors. Studies with available lipid measurements were included. Quantitative data synthesis was performed using random and fixed effects models.

RESULTS

We identified 60 randomized trials, including 147,130 individuals. Overall, using random effects models, SGLT2-inhibitor treatment increased total cholesterol by 0.09 mmol/L (95% CI: 0.06, 0.13), low-density lipoprotein (LDL) cholesterol by 0.08 mmol/L (0.05, 0.10), and high-density lipoprotein (HDL) cholesterol by 0.06 mmol/L (0.05, 0.07), while it reduced triglycerides by 0.10 mmol/L (0.06, 0.14). Fixed effects estimates were similar but with smaller effect sizes for HDL cholesterol and triglycerides. For higher SGLT2-inhibitor doses, there was a nominally higher non-significant effect on lipids and lipoproteins. In Asian compared to non-Asian populations, a slightly larger increase in HDL cholesterol and a decrease in triglycerides were observed, but with similar results for total and LDL cholesterol. Treatment effects on lipids and lipoproteins were generally robust across different SGLT2-inhibitor drugs.

CONCLUSION

In meta-analyses, SGLT2-inhibition increased total, LDL, and HDL cholesterol and decreased triglycerides. Effect sizes varied slightly by drug dose and ethnicity but were generally robust by drug type.

Sodium-glucose co-transporter protein 2 (SGLT2) inhibitors for people with chronic kidney disease and diabetes

BACKGROUND

Diabetes is associated with high risks of premature chronic kidney disease (CKD), cardiovascular diseases, cardiovascular death and impaired quality of life. People with diabetes are more likely to develop kidney impairment, and approximately one in three adults with diabetes have CKD. People with CKD and diabetes experience a substantially higher risk of cardiovascular outcomes. Sodium-glucose co-transporter protein 2 (SGLT2) inhibitors have shown potential effects in preventing kidney and cardiovascular outcomes in people with CKD and diabetes. However, new trials are emerging rapidly, and evidence synthesis is essential to summarising cumulative evidence.

OBJECTIVES

This review aimed to assess the benefits and harms of SGLT2 inhibitors for people with CKD and diabetes.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 17 November 2023 using a search strategy designed by an Information Specialist. Studies in the Register are continually identified through regular searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Randomised controlled studies were eligible if they evaluated SGLT2 inhibitors versus placebo, standard care or other glucose-lowering agents in people with CKD and diabetes. CKD includes all stages (from 1 to 5), including dialysis patients.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the study risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The primary review outcomes were all-cause death, 3-point and 4-point major adverse cardiovascular events (MACE), fatal or nonfatal myocardial infarction (MI), fatal or nonfatal stroke, and kidney failure.

MAIN RESULTS

Fifty-three studies randomising 65,241 people with CKD and diabetes were included. SGLT2 inhibitors with or without other background treatments were compared to placebo, standard care, sulfonylurea, dipeptidyl peptidase-4 (DPP-4) inhibitors, or insulin. In the majority of domains, the risks of bias in the included studies were low or unclear. No studies evaluated the treatment in children or in people treated with dialysis. No studies compared SGLT2 inhibitors with glucagon-like peptide-1 receptor agonists or tirzepatide. Compared to placebo, SGLT2 inhibitors decreased the risk of all-cause death (20 studies, 44,397 participants: RR 0.85, 95% CI 0.78 to 0.94; I2 = 0%; high certainty) and cardiovascular death (16 studies, 43,792 participants: RR 0.83, 95% CI 0.74 to 0.93; I2 = 29%; high certainty). Compared to placebo, SGLT2 inhibitors probably make little or no difference to the risk of fatal or nonfatal MI (2 studies, 13,726 participants: RR 0.95, 95% CI 0.80 to 1.14; I2 = 24%; moderate certainty), and fatal or nonfatal stroke (2 studies, 13,726 participants: RR 1.07, 95% CI 0.88 to 1.30; I2 = 0%; moderate certainty). Compared to placebo, SGLT2 inhibitors probably decrease 3-point MACE (7 studies, 38,320 participants: RR 0.89, 95% CI 0.81 to 0.98; I2 = 46%; moderate certainty), and 4-point MACE (4 studies, 23,539 participants: RR 0.82, 95% CI 0.70 to 0.96; I2 = 77%; moderate certainty), and decrease hospital admission due to heart failure (6 studies, 28,339 participants: RR 0.70, 95% CI 0.62 to 0.79; I2 = 17%; high certainty). Compared to placebo, SGLT2 inhibitors may decrease creatinine clearance (1 study, 132 participants: MD -2.63 mL/min, 95% CI -5.19 to -0.07; low certainty) and probably decrease the doubling of serum creatinine (2 studies, 12,647 participants: RR 0.70, 95% CI 0.56 to 0.89; I2 = 53%; moderate certainty). SGLT2 inhibitors decrease the risk of kidney failure (6 studies, 11,232 participants: RR 0.70, 95% CI 0.62 to 0.79; I2 = 0%; high certainty), and kidney composite outcomes (generally reported as kidney failure, kidney death with or without ≥ 40% decrease in estimated glomerular filtration rate (eGFR)) (7 studies, 36,380 participants: RR 0.68, 95% CI 0.59 to 0.78; I2 = 25%; high certainty) compared to placebo. Compared to placebo, SGLT2 inhibitors incur less hypoglycaemia (16 studies, 28,322 participants: RR 0.93, 95% CI 0.89 to 0.98; I2 = 0%; high certainty), and hypoglycaemia requiring third-party assistance (14 studies, 26,478 participants: RR 0.75, 95% CI 0.65 to 0.88; I2 = 0%; high certainty), and probably decrease the withdrawal from treatment due to adverse events (15 studies, 16,622 participants: RR 0.94, 95% CI 0.82 to 1.08; I2 = 16%; moderate certainty). The effects of SGLT2 inhibitors on eGFR, amputation and fracture were uncertain. No studies evaluated the effects of treatment on fatigue, life participation, or lactic acidosis. The effects of SGLT2 inhibitors compared to standard care alone, sulfonylurea, DPP-4 inhibitors, or insulin were uncertain.

AUTHORS' CONCLUSIONS

SGLT2 inhibitors alone or added to standard care decrease all-cause death, cardiovascular death, and kidney failure and probably decrease major cardiovascular events while incurring less hypoglycaemia compared to placebo in people with CKD and diabetes.

Effectiveness and Safety of Sodium-Glucose Cotransporter 2 Inhibitors Added to Dual or Triple Treatment in Patients with Type 2 Diabetes Mellitus

INTRODUCTION

We evaluated the effectiveness and safety of sodium-glucose cotransporter 2 inhibitor (SGLT2i) add-on treatment in patients with type 2 diabetes mellitus (T2DM) in the real-world setting.

METHODS

This single-center retrospective study used the clinical database of Seoul National University Hospital in South Korea. Patients who received metformin monotherapy or combination therapy with ≥ 1 other oral hypoglycemic medication and had a baseline glycosylated hemoglobin (HbA1c) between 7.0% and 10.5% were included. Propensity score matching was applied between patients treated with and without SGLT2 inhibitors (SGLT2i and non-SGLT2i groups, respectively). Changes in HbA1c from baseline to week 26 were compared between the SGLT2i and non-SGLT2i groups, and risk of adverse events (AE) were also assessed.

RESULTS

A total of 1106 patients were included. At week 26, HbA1c was significantly more reduced by 0.35 percentage points in the SGLT2i group than in the non-SGLT2i group (95% CI 0.30-0.41, P < 0.001). Likewise, the proportion of patients achieving HbA1c < 7% was also significantly higher (51.9% vs. 37.6%, P < 0.05) in the SGLT2i group than in the non-SGLT2i group. The risk of adverse events in the SGLT2i group was mostly comparable with those in the non-SGLT2i group except for diseases of the liver, pain, hypertensive diseases, and metabolic disorders, which showed significantly higher odds in the SGLT2i group.

CONCLUSIONS

SGLT2i add-on treatment is an effective and safe therapeutic option for patients with T2DM in the real-world practice setting.

Randomized Trial Comparing SGLT2 Inhibition and Hydrochlorothiazide on Sympathetic Traffic in Type 2 Diabetes

Introduction

Reductions in sympathetic nervous system activity may contribute to beneficial effects of sodium glucose cotransporter 2 (SGLT2) inhibition on cardiovascular outcomes. Therefore, we tested the hypothesis that SGLT2 inhibition with empagliflozin (Empa) lowers muscle sympathetic nerve activity (MSNA) in patients with type 2 diabetes mellitus (T2DM) compared with hydrochlorothiazide (HCT) to discern SGLT2-specific actions from responses to increased natriuresis.

Methods

We randomized patients with T2DM on metformin monotherapy to either 25 mg/d Empa (n = 20) or 25 mg/d HCT (n = 21) for 6 weeks in a parallel, double-blind fashion. We assessed MSNA by peroneal microneurography, blood pressure, cardiovascular and metabolic biomarkers at baseline and at the end of treatment.

Results

Both drugs elicited volume depletion, as indicated by increased thoracic impedance. Compared with HCT, Empa caused 1.23 kg more body weight loss (P = 0.011) and improved glycemic control. Seated systolic blood pressure decreased with both treatments (P < 0.002). MSNA did not change significantly with either treatment; however, MSNA changes were negatively correlated with changes in body weight on Empa (P = 0.042) and on HCT(P = 0.001). The relationship was shifted to lower MSNA on Empa compared with HCT (P = 0.002).

Conclusion

Increased renal sodium excretion eliciting body weight loss may promote sympathetic activation. However, sympathetic excitation in the face of increased sodium loss may be attenuated by SGLT2 inhibitor-specific actions.

Dose-dependent renoprotection efficacy of sglt2 inhibitors in type 2 diabetes: systematic review and network meta-analysis

AIM

To compare the relative effects of different dosages of sodium-glucose cotransport inhibitors (SGLT2i) for renoprotection in Type 2 diabetes mellitus.

METHODS

The study searched different databases (PubMed, Embase, Scopus, and Web of Science) for studies comparing dose-dependent renoprotective efficacy defined as a decline in eGFR with the different "-flozins namely Empagliflozin, Canagliflozin, Dapagliflozin, Ertugliflozin, Ipragliflozin, Luseogliflozin, Remogliflozin and Sotagliflozin. The studies were compared with the Bayesian approach of network meta-analysis coupled with the random-effect model using the Cochrane risk of bias tool (RoB 2.0), and the surface under the cumulative ranking curve (SUCRA) score was allotted to each dosage of different SGLT-2i.

RESULTS

A total of 43,434 citations were identified, out of which forty-five randomized trials with 48,067 patients, mentioning the flozin dose and eGFR as an endpoint, were found to be eligible for further analysis. The median duration of the follow-up in the trials was 12 months (IQR 5.5-16 months). Canagliflozin 100 mg demonstrated distinct eGFR benefit with an odds ratio of 2.3 (CI 0.72-3.9) compared to placebo. A statistically non-significant eGFR benefit was observed with all other "-flozins." Canagliflozin 100 mg drug dose category showed the highest sucra rank probability score of 93%, followed by the Canagliflozin 300 mg and Dapagliflozin 5 mg with sucra rank probability scores of 69% and 65%, respectively. The Flozin-dose assessment against eGFR was similar to the albumin-creatinine ratios as the secondary endpoint in the SUCRA ranking.

CONCLUSION

The renoprotective efficacy of SGLT2i is independent of the incremental doses suggesting lower doses may suffice for renal outcomes.

Glucometabolic control of once-weekly dulaglutide switched from DPP4 inhibitor versus daily empagliflozin add-on in patients with type 2 diabetes inadequately controlled with metformin, sulfonylurea, and DPP4 inhibitor: A randomised trial

AIMS

To compare the effectiveness and safety of empagliflozin and dulaglutide in patients with type 2 diabetes (T2D) inadequately controlled by oral triple therapy.

METHODS

In this 24-week, multi-center, randomized trial, patients with T2D and HbA1c level ≥7.5% (58 mmol/mol) on metformin, sulfonylurea, and dipeptidyl peptidase 4 inhibitor (DPP4-i) were randomly assigned into two groups: daily empagliflozin add-on or once-weekly dulaglutide switched from DPP4-i. The primary endpoint was changes from baseline HbA1c at 24 weeks.

RESULTS

In total, 152 patients were recruited to the empagliflozin-added quadruple group (n = 76) or the switched-to-dulaglutide triple group (n = 76). At week 24, both groups showed significant reduction in HbA1c level from baseline with greater reduction with empagliflozin (the mean treatment difference: -0.27% [95% CI -0.50 to -0.04, p = 0.024]) (-2.88 mmol/mol [95% CI -5.37 to -0.39], p = 0.024). Empagliflozin significantly reduced body weight from baseline to week 24 (-1.72 kg [95% CI -1.98 to -0.59, p < 0.001]). No serious adverse events were reported with either empagliflozin or dulaglutide.

CONCLUSIONS

Empagliflozin, compared with once-weekly dulaglutide switched from DPP4-i, demonstrated greater HbA1c reduction and weight loss in patients with T2D inadequately controlled with metformin, sulfonylurea, and DPP4-i.

Safety and effectiveness of empagliflozin in clinical practice as monotherapy or with other glucose-lowering drugs in Japanese patients with type 2 diabetes: subgroup analysis of a 3-year post-marketing surveillance study

BACKGROUND

Sodium-glucose co-transporter-2 (SGLT2) inhibitors such as empagliflozin are increasingly prescribed as initial glucose-lowering drugs for type 2 diabetes (T2D), based on their cardiorenal benefits. However, information regarding the safety and the effectiveness of monotherapy with SGLT2 inhibitors in routine clinical practice is limited.

RESEARCH DESIGN AND METHODS

We analyzed data from a prospective, 3-year, post-marketing surveillance study of empagliflozin in Japan. We evaluated adverse drug reactions (ADRs) (the primary endpoint) and glycemic effectiveness with or without other glucose-lowering drugs.

RESULTS

7931 T2D patients were treated with empagliflozin. At baseline, mean age was 58.7 years, 63.0% were male, and 1835 (23.14%) were not receiving other glucose-lowering drugs. ADRs occurred in 141 (7.68%) and 875 (14.62%) patients initiating empagliflozin as monotherapy or combination therapy, respectively. The most frequent ADRs of special interest with empagliflozin as monotherapy or combination therapy were urinary tract infections (0.82% and 1.14% of patients, respectively) and excessive/frequent urination (0.65%, 1.50%). At last observation, glycated hemoglobin level was reduced by a mean of 0.78% with empagliflozin monotherapy (from baseline mean of 7.55%) and 0.74% with combination therapy (baseline 8.16%).

CONCLUSIONS

Empagliflozin is well tolerated and effective in clinical practice in Japan when initiated as monotherapy or combination therapy.

Emphysematous Kidney Related to the Use of Empagliflozin in a Diabetic Woman

Background/Objective

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are part of the treatment for hyperglycemia in patients with diabetes. These drugs have shown important benefits including cardiovascular and renal protection among people with diabetes.

Case Report

We report a case of a 60-year-old woman with diabetes who presented to the emergency department complaining of left flank pain radiating to the groin. The patient was on multiple antidiabetic medications, including a recently added empagliflozin, considering the difficulty in controlling hyperglycemia. She quickly developed severe sepsis with shock, and imaging studies of the abdomen revealed the presence of encapsulated gas in the left kidney compatible with emphysematous pyelonephritis (EPN). There was no presence of nephrolithiasis or other anatomical or structural abnormality that could have precipitated this focal renal infection.Besides antimicrobials, fluid resuscitation, and vasopressor agents, an emergent surgical nephrectomy, as well as intensive care, was required until the patient fully recovered. Escherichia coli was isolated from the initial blood cultures, and ceftriaxone was administered. The patient was subsequently discharged home in stable condition. Two months later, the patient was readmitted with near-syncope and abdominal pain, which was found to be related to small bowel obstruction. The patient decompensated rapidly and had a cardiac arrest even before surgical evaluation. She was resuscitated and admitted to the intensive care unit but showed no signs of neurologic recovery after the anoxic event. She did not survive this hospitalization.

Discussion

The exposure of SGLT2 inhibitors in this patient seemed to have been the precipitating factor for development of complicated pyelonephritis with gas gangrene. EPN is a consequence of a severe renal parenchymal infection, which carries high mortality even with prompt treatment.

Conclusion

Use of SGLT2 inhibitors has expanded worldwide as there are clear clinical benefits, but we need to recognize their uncommon yet potentially fatal complications, such as EPN.

Risk of diabetic ketoacidosis of SGLT2 inhibitors in patients with type 2 diabetes: a systematic review and network meta-analysis of randomized controlled trials

Background: Sodium-glucose cotransporter-2 (SGLT2) inhibitors have proven to be effective in improving glycemic control in patients with type 2 diabetes mellitus (T2DM). However, the risk of diabetic ketoacidosis (DKA) in patients remains unclear. The purpose of this study is to conduct this systematic review and network meta-analysis for the risk of DKA of SGLT2 inhibitors in patients with T2DM. Methods: We searched for randomized controlled trials (RCTs) concerning SGLT2 inhibitors in patients with T2DM in PubMed, EMBASE (Ovid SP), Cochrane Central Register of Controlled Trials (Ovid SP), and ClinicalTrials.gov from inception to January 2022. The primary outcomes were the risk of DKA. We assessed the sparse network with a fixed-effect model and consistency model in a frequentist framework with a graph-theoretical method by the netmeta package in R. We assessed the evidence quality of evidence of outcomes according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: In total, 36 studies involving 52,264 patients were included. The network showed that there was no significant difference observed among SGLT2 inhibitors, other active antidiabetic drugs, and placebo in the risk of DKA. There was no significant difference in the DKA risk between different doses of SGLT2 inhibitors. The certainty of the evidence ranged from very low to moderate. The probabilities of rankings and P-score showed that compared to placebo, SGLT2 inhibitors might increase the risk of DKA (P-score = 0.5298). Canagliflozin might have a higher DKA risk than other SGLT2 inhibitors (P-score = 0.7388). Conclusion: Neither SGLT2 inhibitors nor other active antidiabetic drugs were associated with an increased risk of DKA compared to placebo, and the risk of DKA with SGLT2 inhibitors was not found to be dose-dependent. In addition, the use of canagliflozin was less advisable than other SGLT2 inhibitors according to the rankings and P-score.

A Comprehensive Review on Weight Loss Associated with Anti-Diabetic Medications

Obesity is a complex metabolic condition that can have a negative impact on one's health and even result in mortality. The management of obesity has been addressed in a number of ways, including lifestyle changes, medication using appetite suppressants and thermogenics, and bariatric surgery for individuals who are severely obese. Liraglutide and semaglutide are two of the five Food and Drug Administration (FDA)-approved anti-obesity drugs that are FDA-approved agents for the treatment of type 2 diabetes mellitus (T2DM) patients. In order to highlight the positive effects of these drugs as anti-obesity treatments, we analyzed the weight loss effects of T2DM agents that have demonstrated weight loss effects in this study by evaluating clinical studies that were published for each agent. Many clinical studies have revealed that some antihyperglycemic medications can help people lose weight, while others either cause weight gain or neutral results. Acarbose has mild weight loss effects and metformin and sodium-dependent glucose cotransporter proteins-2 (SGLT-2) inhibitors have modest weight loss effects; however, some glucagon-like peptide-1 (GLP-1) receptor agonists had the greatest impact on weight loss. Dipeptidyl peptidase 4 (DPP-4) inhibitors showed a neutral or mild weight loss effect. To sum up, some of the GLP-1 agonist drugs show promise as weight-loss treatments.

Neutral effects of SGLT2 inhibitors in acute coronary syndromes, peripheral arterial occlusive disease, or ischemic stroke: a meta-analysis of randomized controlled trials

BACKGROUND

Patients with type 2 diabetes are at increased risk for cardiovascular diseases. Sodium-glucose transport 2 inhibitors (SGLT2i) have been shown to enhance cardiovascular health since their debut as a second-line therapy for diabetes. Acute coronary syndrome (ACS), peripheral arterial occlusive disease (PAOD), and ischemic stroke (IS) are types of atherosclerotic cardiovascular disease (ASCVD), although the benefits of treating these disorders have not been shown consistently.

METHODS

We searched four databases (PubMed, Embase, the Cochrane library, and clinicaltrial.gov) for randomized clinical trials (RCTs) until November of 2022. Comparisons were made between SGLT2i-treated and control individuals with type 2 diabetes. Primary outcomes were ACS, PAOD, and IS; secondary outcomes included cardiovascular mortality and all-cause mortality. Risk ratio (RR) and 95% confidence intervals (CI) were determined using a fixed effects model. Cochrane's risk-of-bias (RoB2) instrument was used to assess the validity of each study that met the inclusion criteria.

RESULTS

We enrolled 79,504 patients with type 2 diabetes from 43 RCTs. There was no difference in the risk of ACS (RR = 0.97, 95% CI 0.89-1.05), PAOD (RR = 0.98, 95% CI 0.78-1.24), or IS (RR = 0.95, 95% CI 0.79-1.14) among patients who took an SGLT2i compared to those who took a placebo or oral hypoglycemic drugs. Subgroup analysis revealed that none of the SGLT2i treatments (canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin) significantly altered outcomes when analyzed separately. Consistent with prior findings, SGLT2i reduced the risk of cardiovascular mortality (RR = 0.85, 95% CI 0.77-0.93) and all-cause mortality (RR = 0.88, 95% CI 0.82-0.94).

CONCLUSION

Our results appear to contradict the mainstream concepts regarding the cardiovascular effects of SGLT2i since we found no significant therapeutic benefits in SGLT2i to reduce the incidence of ACS, PAOD, or IS when compared to placebo or oral hypoglycemic drugs.

Comparative efficacy of sodium-glucose co-transporter-2 inhibitors, glucagon-like peptide-1 receptor agonists and non-steroidal mineralocorticoid receptor antagonists in chronic kidney disease and type 2 diabetes: A systematic review and network meta-analysis

AIM

To compare the relative efficacy of sodium-glucose co-transporter 2 inhibitors (SGLT-2is), glucagon-like peptide-1 receptor agonists (GLP-1RAs) and non-steroidal mineralocorticoid receptor antagonists (nsMRAs) in improving the cardiovascular and renal outcomes in patients with type 2 diabetes (T2D) and chronic kidney disease (CKD).

MATERIALS AND METHODS

We searched PubMed, Embase and Cochrane Library from inception through 25 November 2022. We selected randomized controlled trials that studied patients with CKD and T2D with a follow-up of at least 24 weeks and compared SGLT-2is, GLP-1RAs and nsMRAs with each other and with placebo. Primary outcomes were major adverse cardiovascular events (MACE) and composite renal outcomes (CRO). Secondary outcomes were cardiovascular death, all-cause death, stroke, myocardial infarction and heart failure hospitalization (HFH). A frequentist approach was used to pool risk ratios (RRs) with 95% confidence intervals (CIs).

RESULTS

Twenty-nine studies with 50 938 participants for MACE and 49 965 participants for CRO were included. SGLT-2is did not significantly reduce MACE but were associated with significantly lower risks of CRO compared with GLP-1RAs (RR, 0.77; 95% CI, 0.64-0.91; P = .003) and nsMRAs (RR, 0.78; 95% CI, 0.68-0.90; P = .001). Compared with GLP-1RAs and nsMRAs, SGLT-2is significantly reduced risks of HFH by 31% (RR, 0.69; 95% CI, 0.55-0.88; P = .002) and 22% (RR, 0.78; 95% CI, 0.63-0.95; P = .016), respectively, but did not significantly reduce other secondary outcomes. There were no significant differences between GLP-1RAs and nsMRAs in lowering all outcomes.

CONCLUSIONS

SGLT-2is were associated with better cardiorenal protection than GLP-1RAs and nsMRAs in patients with CKD and T2D.

Empagliflozin in Adults with Chronic Kidney Disease (CKD): Current Evidence and Place in Therapy

Chronic kidney disease guidelines and disease modifying therapy have seen a dramatic shift in the last 5 years. The SGLT2 inhibitor class of medications has been catapulted from hyperglycemia management medications, to cardiovascular and kidney disease improvement therapies. Multiple trials looking at dedicated cardiovascular and kidney endpoints have resulted in favorable results. This review will target empagliflozin and the exciting journey that it has taken along this path. Empagliflozin has been studied for hyperglycemia, cardiovascular, and kidney hard outcome endpoints. Both patients with diabetes and without have been rigorously studied and shown surprising results. The major implications for patients on empagliflozin will be shown. Future studies and directions are highly anticipated to add to the growing knowledge of the SGLT2 inhibitor class, as well as discover possibilities for new disease states to benefit from empagliflozin.

Mechanisms underlying the blood pressure-lowering effects of empagliflozin, losartan and their combination in people with type 2 diabetes: A secondary analysis of a randomized crossover trial

AIM

To study the effects of the sodium-glucose co-transporter-2 (SGLT2) inhibitor empagliflozin, the angiotensin receptor blocker (ARB) losartan, and their combination on blood pressure, while studying the mechanisms potentially involved.

METHODS

A total of 24 people with type 2 diabetes (T2D) (age: 66 ± 6 years; body mass index: 31.0 ± 3 kg/m² ; estimated glomerular filtration rate: 90 ml/min/1.73m² ) received a 1-week treatment with empagliflozin 10 mg once daily, losartan 50 mg once daily, their combination, and placebo, in a randomized double-blind crossover design, with 4-week washout periods in between. Blood pressure, arterial stiffness, autonomic nervous system activity and plasma volume, extracellular fluid and serum albumin were assessed.

RESULTS

Versus placebo (139 mmHg), empagliflozin reduced systolic blood pressure (SBP) by 8 mmHg (P = .001), losartan by 12 mmHg (P = .001) and empagliflozin + losartan by 15 mmHg (P < .001). Combination therapy had a larger SBP-lowering effect versus empagliflozin monotherapy (-7 [95% CI -12; -2] mmHg) and numerically larger effects versus losartan monotherapy (-3 [-8; 2] mmHg). Empagliflozin reduced sympathetic nervous system (SNS) activity, arterial stiffness and extracellular fluid, while increasing serum albumin. Losartan reduced SNS activity and arterial stiffness. Combination therapy induced volume contraction variables, together with a reduction in SNS activity and arterial stiffness.

CONCLUSION

In people with T2D, SGLT2 inhibition in combination with an ARB had a larger blood pressure-lowering effect versus placebo than either of the drugs alone. Our data further suggest that the mechanisms underlying these blood pressure reductions at least partially differ between these agents.

Budget Impact Analysis of Empagliflozin in the Treatment of Patients With Type 2 Diabetes With Established Cardiovascular Disease in South Africa

OBJECTIVES

This study aimed to estimate the budget impact and affordability of empagliflozin added to usual care compared with usual care alone, in a diabetic population with established cardiovascular disease, from a private healthcare payer perspective in South Africa.

METHODS

A budget impact model was adapted and localized. Epidemiological data were obtained from the South African Council for Medical Schemes. Clinical event rates were sourced from the EMPA-REG OUTCOME trial and drug costs from list prices. Clinical event costs were derived from a claims data analysis of the South African private healthcare sector and microcosting. Scenario analyses were performed on select inputs. The modeled outcomes included annual budget impact of empagliflozin, the incremental cost per life per month, cardiovascular deaths averted, and incremental cost per life saved, over 3 years.

RESULTS

A total of 9 503 patients were eligible for empagliflozin (year 1), 12 670 (year 2), and 16 947 (year 3). The incremental cost was $1 272 297, $1 764 705, and $2 455 235, for years 1 to 3, respectively. The incremental cost per beneficiary per month was calculated as $0.012 (year 1), $0.016 (year 2), and $0.023 (year 3). The model estimated a 38.6% reduction in cardiovascular deaths, 305 lives saved, and an incremental cost per life saved of $17 999.

CONCLUSIONS

Adding empagliflozin to usual care has a marginal budget implication and is highly affordable for private healthcare payers, with an acceptable incremental cost based on clinical outcomes.

Recommendations for Early and Comprehensive Management of Type 2 Diabetes and Its Related Cardio-Renal Complications

Type 2 diabetes (T2D) is a global health problem accompanied by an elevated risk of complications, the most common being cardiac and renal diseases. In Lebanon, the prevalence of T2D is estimated at 8-13%. Local medical practice generally suffers from clinical inertia, with gaps in the yearly assessment of clinical manifestations and suboptimal screening for major complications. The joint statement presented here, endorsed by five Lebanese scientific medical societies, aims at providing physicians in Lebanon with a tool for early, effective, and comprehensive care of patients with T2D. Findings from major randomized clinical trials of antidiabetic medications with cardio-renal benefits are presented, together with recommendations from international medical societies. Optimal care should be multidisciplinary and should include a multifactorial risk assessment, lifestyle modifications, and a regular evaluation of risks, including the risks for cardiovascular (CV) and renal complications. With international guidelines supporting a shift in T2D management from glucose-lowering agents to disease-modifying drugs, the present statement recommends treatment initiation with metformin, followed by the addition of sodium-glucose cotransporter 2 inhibitors or glucagon-like peptide-1 receptor agonists due to their CV and renal protection properties, whenever possible. In addition to the selection of the most appropriate pharmacological therapy, efforts should be made to provide continuous education to patients about their disease, with the aim to achieve a patient-centered approach and to foster self-management and adherence to the medical plan. Increasing the level of patient engagement is expected to be associated with favorable health outcomes. Finally, this statement recommends setting an achievable individualized management plan and conducting regular follow-ups to monitor the patients' glycemic status and assess their risks every 3-6 months.

Efficacy and safety of empagliflozin: a "real-world" experience from Saudi Arabia

BACKGROUND

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are new agents for treating type 2 diabetes. In addition to the glycemic benefits, these agents provide cardiorenal protection in patients with diabetes and without diabetes. There is consistent evidence that these agents increase the risk of genitourinary infections and dehydration, but randomized controlled trials have not included patients from the Middle East.

OBJECTIVES

Determine the efficacy and safety of empagliflozin, specifically whether the genitourinary infection risk differs in our population and whether there is an increased risk of dehydration, ketoacidosis, hypoglycemia, and hospitalization with fasting.

DESIGN

Retrospective review of medical records.

SETTINGS

Department of medicine at tertiary care center.

PATIENTS AND METHODS

We reviewed the electronic records of patients with type 2 diabetes who took empagliflozin from 1 December 2018 to 30 November 2019. We collected safety and efficacy data for 12 months from the initiation of treatment.

MAIN OUTCOMES MEASURES

Glycemic and weight loss efficacy, risk of hospitalization due to hypoglycemia, dehydration, and genitourinary infections.

SAMPLE SIZE

637 patients.

RESULTS

We observed an improvement in glycated hemoglobin, a 4.2% weight loss, improved left ventricular function, stable serum creatinine, and reduced albuminuria. Our patients did not have an increased risk of genitourinary infections, hypoglycemia, dehydration, ketoacidosis, or hospitalizations. Fasting did not increase the incidence of adverse events.

CONCLUSIONS

Empagliflozin is safe and effective in our local population. We hypothesize that glycosuria induced by empagliflozin is not the sole contributor to the increased risk of genitourinary infections. Local hygiene and circumcision might reduce this risk. Empagliflozin can be used safely during fasting.

LIMITATIONS

Retrospective design.

CONFLICT OF INTEREST

None.

New Insights into the Use of Empagliflozin-A Comprehensive Review

Empagliflozin is a relatively new drug that, as an inhibitor of the sodium−glucose cotransporter 2 (SGLT2), causes increased urinary glucose excretion and thus contributes to improved glycemic control, better glucose metabolism, reduced glucotoxicity and insulin resistance. Although its original use was to induce a hypoglycemic effect in patients with type 2 diabetes mellitus (T2DM), empagliflozin has also shown a number of other beneficial effects by demonstrating a nephroprotective effect, and it has proven to be a breakthrough in the treatment of heart failure (HF). Empagliflozin has been shown to reduce hospitalizations for HF and the number of deaths from cardiovascular causes. Empagliflozin treatment also reduces the incidence of renal events, including death from renal causes, as well as the risk of end-stage renal failure. Empagliflozin appears to be a fairly well-tolerated and safe drug. In patients with inadequate glycemic control, empagliflozin used in monotherapy or as an adjunct to therapy effectively lowers fasting blood glucose, postprandial blood glucose, average daily glucose levels, glycated hemoglobin A1C (HbA1C) and also leads to significant weight reduction in patients with T2DM. Unfortunately, there are some limitations, e.g., severe hypersensitivity reaction to the drug and a glomerular filtration rate (GFR) < 30 mL/min/1.73 m2. As with any drug, empagliflozin is also characterized by several side effects among which symptomatic hypotension, troublesome genital fungal infections, urinary tract infections and rare ketoacidosis are characteristic.

Assessment of the Safety, Efficacy, and Benefit of Empagliflozin in Patients With Type 2 Diabetes Mellitus (T2DM) and Heart Failure With Reduced Ejection Fraction (HFrEF) at High Risk for Cardiovascular Events

Background Since the increasing prevalence of type 2 diabetes mellitus (T2DM), heart failure coexisting with it has had a significant impact on clinical management and prognosis. Patients with T2DM and heart failure with reduced ejection fraction (HFrEF) have increased mortality and morbidity. Empagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, is widely acknowledged to reduce cardiovascular risk in T2DM patients. We wanted to assess the composite outcomes of heart failure, cardiovascular death, and hospitalization following the start of empagliflozin therapy in the Saudi population. Methods This is a retrospective observational study conducted at King Fahad Armed Forces Hospital-Jeddah. We included patients aged 18 or older, male or female, with T2DM with HFrEF <40% and with a risk of cardiovascular events who were treated with empagliflozin 25 mg once daily as combination therapy and patients using other diabetic agents without empagliflozin as the comparative group. Results A total of 195 patients with T2DM and HFrEF who were at high risk for cardiovascular (CV) events were included in the study. Regarding gender, most of the patients (82.1%) were male with an average age of 61.28 ± 9.92. The patients were divided into 71 individuals who received empagliflozin and 124 who did not. When comparing the surgical procedure and comorbid status of the patients, coronary artery bypass graft (1.4%), coronary artery disease (5.6%), dyslipidemia (5.6%), and ischemic cardiomyopathy (0%) were found compared to the non-empagliflozin group. Meanwhile, hypertension was found to be 71.8% and ischemic heart disease was 50.7% in empagliflozin patients. Furthermore, only dyslipidemia differed significantly (p <0.001) between the empagliflozin and non-empagliflozin groups of patients. However, no significant differences were observed between the average low-density lipoprotein (p = 0.990) and high-density lipoprotein (p = 0.399). There was no significant difference observed in the primary outcome of CV deaths or hospital admission of patients between empagliflozin and non-empagliflozin. No deaths were reported in either of the comparative groups in our study. Conclusion In this study, there was no significant difference observed in hospital admission of the patients between the empagliflozin and non-empagliflozin groups. No cardiovascular mortality was reported in the study population. Further matched group comparative studies or placebo-controlled studies are required to compare the existing evidence of the impact of empagliflozin on T2DM patients with HFrEF and at high risk for CV deaths or hospital admission.

Efficacy and Safety of Sodium Glucose Cotransporter-2 (SGLT2) Inhibitors in Patients With Diabetes and Chronic Kidney Disease (CKD): A Meta-analysis of Randomized Control Trials

The current meta-analysis aims to assess the efficacy and safety of sodium glucose cotransporter 2 (SGLT2) inhibitors in individuals with diabetes and chronic kidney disease (CKD). The current meta-analysis was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was conducted to identify all relevant studies related to the efficacy and safety of SGLT2 inhibitors in individuals with diabetes and CKD. The search was undertaken in PubMed, EMBASE, and Cochrane Library from January 2000 to September 2022. The primary efficacy outcome assessed in the current meta-analysis included major adverse cardiovascular events (MACE). Other efficacy outcomes included all-cause mortality and change in hemoglobin A1c (HbA1c) (%). Safety outcomes included serious adverse events, acute kidney injury, hypoglycemia, and hyperkalemia. In total 11 articles met the inclusion criteria and were included in the final analysis enrolling 27520 patients (14491 in the SGLT2 inhibitors and 13029 in the placebo group). The findings of this meta-analysis have shown that the risk of MACE and all-cause mortality was significantly lower in patients receiving SGLT2 inhibitors. Additionally, Hb1AC change was also significantly greater in SGLT2 inhibitors group. In relation to safety outcomes, serious adverse events, risk of acute kidney injury, and hyperkalemia were significantly lower in the SGLT2 inhibitors group. The SGLT2 inhibitors significantly decreased the risk of major cardiovascular events and all-cause mortality in patients with CKD and diabetes. Furthermore, SGLT2 inhibitor is also effective in reducing Hb1Ac levels in patients.

SGLT2 Inhibitors: New Hope for the Treatment of Acute Myocardial Infarction?

Among all of the new antidiabetic drugs, an increasing number of studies have evaluated the relationship between the sodium-glucose cotransporter 2 inhibitors (SGLT2i) and acute myocardial infarction (AMI). Since SGLT2i like empagliflozin, canagliflozin, and recently, dapagliflozin have shown impressive positive effects in patients with chronic heart failure with reduced ejection fraction (HFrEF), it has increased research interest to explore the cardiac molecular mechanisms underlying the clinical benefits and attracted more attention to the effects of SGLT2i on a series of cardiovascular events. Experimental and clinical data on SGLT2i treatment after AMI is limited. This is a review of the clinical and preclinical effects of SGLT2i, focusing on available data on the effects of SGLT2i in AMI patients with a brief overview of ongoing trials.

Carbohydrate-based drugs launched during 2000-2021

Carbohydrates are fundamental molecules involved in nearly all aspects of lives, such as being involved in formating the genetic and energy materials, supporting the structure of organisms, constituting invasion and host defense systems, and forming antibiotics secondary metabolites. The naturally occurring carbohydrates and their derivatives have been extensively studied as therapeutic agents for the treatment of various diseases. During 2000 to 2021, totally 54 carbohydrate-based drugs which contain carbohydrate moities as the major structural units have been approved as drugs or diagnostic agents. Here we provide a comprehensive review on the chemical structures, activities, and clinical trial results of these carbohydrate-based drugs, which are categorized by their indications into antiviral drugs, antibacterial/antiparasitic drugs, anticancer drugs, antidiabetics drugs, cardiovascular drugs, nervous system drugs, and other agents.

Clinical Benefit of Switching from Low-Dose to High-Dose Empagliflozin in Patients with Type 2 Diabetes

INTRODUCTION

Sodium-dependent glucose cotransporter 2 (SGLT2) inhibitors ameliorate blood glucose levels in patients with type 2 diabetes mellitus (T2DM) by inhibiting the reabsorption of glucose from the kidneys, thus increasing urinary glucose excretion. Most SGLT2 inhibitors have been reported to exert dose-dependent effects. However, little is known about the benefits of increasing the dose of SGLT2 inhibitors in clinical use. The aim of the present study was to investigate the effect of increasing the dose of the SGLT2 inhibitor empagliflozin in T2DM.

METHODS

We collected 52 subjects with T2DM with inadequate glycemic control. The dose of empagliflozin was increased from 10 to 25 mg, taken once daily, and the alterations in glycemic control and several other clinical parameters were evaluated.

RESULTS

The increased dose of empagliflozin significantly ameliorated glycemic control. In addition, body weight (BW), body mass index (BMI), triglyceride (TG), and γ-glutamyltranspeptidase (GGT) were significantly decreased and hematocrit (Hct) was increased. Multivariate logistic regression analyses revealed that baseline diastolic blood pressure (DBP) (odds ratio 1.093, 95% CI 1.019-1.156, P = 0.012) and baseline TG (odds ratio 1.012, 95% CI 1.001-1.023, P = 0.026) were retained as independent predictors for the improvement of hemoglobin A1c (HbA1c) levels. Moreover, multivariate stepwise regression analyses revealed that changes in high-density lipoprotein cholesterol (β - 0.264, 95% CI - 1.217 to 0.000, P = 0.049) and HbA1c (β 0.302, 95% CI 0.077-1.096, P = 0.025) were retained as independent predictors for changes in BMI.

CONCLUSION

Increasing the dose of empagliflozin significantly ameliorated BW, BMI, GGT, TG, fasting plasma glucose and HbA1c and increased Hct in patients with T2DM. Moreover, baseline DBP and TG were independent predictors for the improvement of HbA1c. These findings may provide useful information when considering increasing the dosage of SGLT2 inhibitors in patients with T2DM who have inadequate glycemic control.

The dual role of empagliflozin: Cardio renal protection in T2DM patients

Empagliflozin (Jardiance®) is an insulin independent antihyperglycemic agent used in treatment of T2D.The drug is a sodium glucose cotransporter-2 (SGLT2) inhibitor approved in USA and Europe and other countries of the world. As empagliflozin demonstrates cardioprotective and Reno protective properties its prime target are patients having CVD and CKD complicated by T2D.

This review sheds light on mechanism of action of the drug and with the help of clinical outcomes establishes the use of empagliflozin in T2D patients.

Although empagliflozin is a well-tolerated and easy to administer drug, it has some side effects and contraindications which are discussed in the article to help the reader weigh its beneficial effects against its adverse effect and understand its use in clinical medicine.

Sodium–Glucose Cotransporter 2 Inhibitors in Heart Failure with Preserved Ejection Fraction: Rationale for and Practical Use of a Successful Therapy

Heart failure (HF) with preserved left ventricular ejection fraction is a common disease with a poor prognosis and rising prevalence in the community. The current paradigm of treatment includes symptomatic therapy, such as diuretics, and risk factor control and treatment of comorbidities. According to European guidelines, there is no effective therapy for patients with HF with left ventricular ejection fraction (LVEF) ≥50%, while drugs normally used in HF with reduced LVEF might also be effective for patients with mildly reduced LVEF (40–50%), with a IIB class of recommendation. The recently published EMPEROR-Preserved trial has challenged current guidelines, demonstrating improved outcomes in patients with HF and LVEF >40% with the sodium–glucose cotransporter 2 inhibitor (SGLT2I) empagliflozin, compared with placebo. This result was consistent in patients with and without diabetes as well as in those with LVEF below and above 50%. The authors describe the rationale for this therapy, presenting the main results of the EMPEROR-Preserved trial, and provide some recommendations for the everyday clinical management of HF with preserved left ventricular ejection with an SGLT2I.

Short-Term Treatment with Empagliflozin Resulted in Dehydration and Cardiac Arrest in an Elderly Patient with Specific Complications: A Case Report and Literature Review

Empagliflozin is a sodium-glucose cotransporter-2 inhibitor widely used in the treatment of diabetes mellitus and heart failure. Our case study involved a 68-year-old patient who was admitted to the hospital because of a cerebral infarction. The patient was simultaneously diagnosed with diabetes mellitus and heart failure, for which empagliflozin was initiated. However, food and fluid intake were reduced due to poor appetite. In addition to the side effects of empagliflozin, the patient developed severe dehydration and cardiac arrest. Careful assessment of dehydration and preventive water intake is recommended in elderly patients and those with neurological deficits, especially when receiving empagliflozin.

Semaglutide Initiation in a Type 2 Diabetes Mellitus, Post-Liver Transplant Patient

Objective To describe the process of initiation of semaglutide for complex management of type 2 diabetes mellitus (T2DM) in a patient after liver transplantation. Setting Family medicine clinic. Practice Description A family medicine clinic comprising six physicians with an ambulatory care pharmacist. The pharmacist has direct interaction with patients and providers within the clinic assisting in the management of chronic disease states under a collaborative practice agreement. Practice Innovation A 63-year-old White male with a history of liver transplantation in the context of T2DM, treated with basal-bolus insulin therapy, was referred by his family medicine provider to the ambulatory care pharmacist for diabetes management because of a hemoglobin A1c (HbA1c) level greater than 10%. Semaglutide was initiated and titrated to improve blood glucose control in combination with basal-bolus insulin adjustments taking disease states, cost, and health literacy into consideration. Results The addition of semaglutide, over an eight-month period, assisted with glycemic control to an HbA1c of less than 7%. Conclusion Semaglutide, in addition to basal-bolus insulin therapy, allowed for overall improved glycemic control; however, further studies are needed to evaluate efficacy because of the complexity of diabetes management in this patient population. Throughout the course of treatment of patients with T2DM and organ transplantation, dual monitoring of antidiabetic therapy and antirejection medications is essential to reduce the risk of organ rejection.

Defining the Role of SGLT2 Inhibitors in Primary Care: Time to Think Differently

Disease burden in people with diabetes is mainly driven by long-term complications such as cardiovascular disease, heart failure and chronic kidney disease. This is a consequence of the interconnection between the cardiovascular, renal and metabolic systems, through a continuous chain of events referred to as 'the cardiorenal metabolic continuum'. Increasing evidence suggests that sodium-glucose cotransporter 2 inhibitors (SGLT2is) have beneficial effects across all stages of the cardiorenal metabolic continuum, reducing morbidity and mortality in a wide range of individuals, from those with diabetes and multiple risk factors to those with established heart failure and chronic kidney disease, regardless of the presence of diabetes. Despite this robust evidence base, the complexity of label indications and misconceptions concerning potential side effects have resulted in a lack of clear understanding in primary care regarding the implementation of SGLT2is in clinical practice. With this in mind, we provide an overview of the clinical and economic benefits of SGLT2is across the cardiorenal metabolic continuum together with practical considerations in order to help address some of these concerns and clearly define the role of SGLT2is in primary care as a holistic outcomes-driven treatment with the potential to reduce disease burden across the cardiorenal metabolic spectrum.

Effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors on serum urate levels in patients with and without diabetes: a systematic review and meta-regression of 43 randomized controlled trials

Objectives

Sodium-glucose cotransporter-2 (SGLT2) inhibitors have been found to reduce serum urate in patients with type 2 diabetes mellitus. To evaluate if this effect applies to both patients with and without diabetes, we conducted a systematic review and meta-analysis of SGLT2 inhibitors on serum urate levels in this population.

Methods

Four electronic databases (PubMed, Embase, Cochrane and SCOPUS) were searched on 25 September 2021 for articles published from 1 January 2000 up to 25 September 2021, for studies that examined the effect of SGLT2 inhibitors on serum urate in study subjects. Random-effects meta-analysis was performed, with subgroup analyses on the type of SGLT2 inhibitor agent administered, presence of type 2 diabetes mellitus, presence of chronic kidney disease and drug dose.

Results

A total of 43 randomized controlled trials, with a combined cohort of 31,921 patients, were included. Both patients with [-31.48 μmol/L; 95% confidence interval (CI): -37.35 to -25.60] and without diabetes (-91.38 μmol/L; 95% CI: -126.53 to -56.24) on SGLT2 inhibitors had significantly lower urate levels when compared with placebo. This treatment effect was similarly observed across different types of SGLT2 inhibitors. However, in type 2 diabetes mellitus (T2DM) patients with chronic kidney disease, the reduction in serum urate with SGLT2 inhibitors became insignificant (95% CI: -22.17 to 5.94, p < 0.01).

Conclusion

This study demonstrated that SGLT2 inhibitors are beneficial in reducing serum urate in patients with and without diabetes. SGLT2 inhibitors could therefore contribute to the general treatment of hyperuricaemia.

Comparison of the effects of empagliflozin and glimepiride on endothelial function in patients with type 2 diabetes: A randomized controlled study

Patients with type 2 diabetes who have cardiovascular disease and are receiving empagliflozin have a lower rate of primary composite cardiovascular outcomes. In contrast, glimepiride increases cardiovascular hospitalization when combined with metformin. Here, we assessed the effects of empagliflozin and glimepiride on endothelial function using flow-mediated dilation (FMD). In this prospective, open-label, randomized, parallel-group study, 63 patients with type 2 diabetes received metformin and insulin glargine U100 for 12 weeks. This was followed by additional treatment with empagliflozin or glimepiride for 12 weeks. The primary outcome was the change in the FMD measurement (ΔFMDs) at 24 weeks of additional treatment. Secondary outcomes comprised changes in metabolic markers and body composition. The empagliflozin group (n = 33) and glimepiride group (n = 30) showed no significant differences in ΔFMDs (empagliflozin, −0.11 [95%CI: -1.02, 0.80]%; glimepiride, −0.34 [95%CI: -1.28, 0.60]%; P = 0.73). Additionally, changes in glycated hemoglobin were similar between the two groups. However, a significant difference in body weight change was observed (empagliflozin, −0.58 [95%CI: -1.60, 0.43] kg; glimepiride, 1.20 [95%CI: 0.15, 2.26] kg; P = 0.02). Moreover, a body composition analysis revealed that body fluid volume significantly decreased after empagliflozin treatment (baseline, 35.8 ± 6.8 L; after 12 weeks, −0.33 ± 0.72 L; P = 0.03). Hence, although empagliflozin did not improve endothelial function compared with glimepiride for patients with type 2 diabetes, it did decrease body fluid volumes. Thus, the coronary-protective effect of empagliflozin is not derived from endothelial function protection, but rather from heart failure risk reduction.

Trial registration: This trial was registered on September 13, 2016; UMIN000024001.

Pharmacokinetics and Bioequivalence of Two Empagliflozin, with Evaluation in Healthy Jordanian Subjects under Fasting and Fed Conditions

The current study is a randomized, open-label, two-period, two-sequence, two-way crossover pharmacokinetic study in healthy Jordanian subjects to evaluate the pharmacokinetics and bioequivalence profile of two cases of empagliflozin 10 mg under fasting and fed conditions. The plasma concentrations of empagliflozin were determined using an HPLC-MS/MS method. Tolerability and safety were assessed throughout the study. This study included 26 subjects, 26 in both fasting and fed groups.The pharmacokinetic parameters, which included the area under the concentration–time curve from time zero to infinity (AUC_0–inf) and the final quantifiable concentration (AUC_0–last), maximum serum concentration (C_max), and time to reach the maximum drug concentration (T_max) were found to be within an equivalence margin of 80.00–125.00%. The pharmacokinetic profiles show that the empagliflozin test and parent reference cases were bioequivalent in healthy subjects. The two treatments’ safety evaluations were also comparable.

Impacts of Sodium/Glucose Cotransporter-2 Inhibitors on Circulating Uric Acid Concentrations: A Systematic Review and Meta-Analysis

BACKGROUND

Several trials have assessed the antihyperglycemic effects of sodium/glucose cotransporter-2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2DM). We conducted a quantitative analysis to assess the impact of SGLT2is on serum uric acid (SUA) in patients with T2DM.

METHODS

Placebo-controlled trials published before 13 August 2021 were identified by searching PubMed, Embase, Web of Science, and Scopus. The intervention group received SGLT2i as monotherapy or add-on treatment, and the control group received a placebo that was replaced with SGLT2i. Clinical trials providing changes in SUA were included. The mean change of SUA, glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and body weight were calculated (PROSPERO CRD42021287019).

RESULTS

After screening of 1172 papers, 59 papers were included in the systematic review. A total of 55 trials (122 groups) of 7 types of SGLT2i on patients with T2DM were eligible for meta-analysis. All SGLT2is significantly decreased SUA levels compared with the placebo groups: empagliflozin mean difference (MD) = -40.98 μmol/L, 95% CI [-47.63, -34.32], dapagliflozin MD = -35.17 μmol/L, 95% CI [-39.68, -30.66], canagliflozin MD = -36.27 μmol/L, 95% CI [-41.62, -30.93], luseogliflozin MD = -24.269 μmol/L, 95% CI [-33.31, -15.22], tofogliflozin MD = -19.47 μmol/L, 95% CI [-27.40, -11.55], and ipragliflozin MD = -18.85 μmol/L, 95% CI [-27.20, -10.49]. SGLT2i also decreased FPG, body weight, and HbA1c levels. SUA reduction persisted during long-term treatment with SGLT2i (except for empagliflozin), while the SUA reduction was affected by the duration of diabetes.

CONCLUSIONS

SGLT2i can be a valid therapeutic strategy for patients with T2DM and comorbid hyperuricemia. Besides reducing FPG, body weight, and HbA1c, SGLT2i can significantly decrease SUA levels compared to placebo (Total MD = -34.07 μmol/L, 95% CI [-37.00, -31.14]).

Efficacy and Safety of Empagliflozin in Patients with Type 2 Diabetes Mellitus Fasting During Ramadan: A Real-World Study from Bangladesh

AIM

In Bangladesh, there is a large population of Muslims with type 2 diabetes mellitus (T2DM) who fast during Ramadan. Changes in the pattern of meal and fluid intake during this long-fasting hours may increase the risk of hypoglycaemia, hyperglycaemia, and dehydration. Our key point of focus was to evaluate the efficacy and safety of Empagliflozin, a sodium-glucose co transporter 2 inhibitor (SGLT2i), in patients with T2DM while fasting during Ramadan.

METHODS

This was a 24-weeks, multi-centre, open-label, two-arm parallel-group study. In this prospective type of observational study, we enrolled patients taking Empagliflozin and Metformin with or without a DPP-4 inhibitor in one group (n = 274) and a parallel group (n = 219) who were treated with Metformin with or without a DPP-4 inhibitor. The primary endpoint of this study was HbA1c reduction, weight loss and the number of reported or symptomatic hypoglycemic events. In secondary endpoints, we evaluated the changes from baseline in blood pressure, estimated glomerular filtration rate (eGFR), serum creatinine, and serum electrolyte, the proportion of volume depletion (≥1 event) and incidence of other adverse events (AEs) of interest potentially related to SGLT2 inhibitor.

RESULTS

During Ramadan, HbA1c reduction was significant in Empagliflozin arm (-0.49% vs -0.12%); [p < 0.001]. From before to the end of the study, significant weight reduction was seen in the Empagliflozin arm (-1.4 kg vs -0.09 kg); [p < 0.001]. We observed no significant increase in the incidence of hypoglycemia (0.7% vs 0.4%, p = 0.267) and volume depletion (2.6% vs 1.8%; p = 0.55) in both arm. All these milder forms events did not require any hospital admission. There was no report of serious adverse events or any discontinuation, or reduction of prescribed doses of empagliflozin during Ramadan.

CONCLUSION

Empagliflozin is efficacious and safe for treating adults with T2DM during Ramadan.

Effects of Sodium-Glucose Cotransporter-2 Inhibitors on Weight in Type 2 Diabetes Mellitus and Therapeutic Regimen Recommendation

AIMS

The present study is aimed at exploring the effects of sodium-glucose cotransporter-2 (SGLT-2) inhibitors on weight in type 2 diabetes mellitus (T2DM) and therapeutic regimen recommendations.

METHODS

20,019 patients with T2DM were enrolled. The maximal effect (E _max) models, whose evaluation index was change rate of body weight from baseline value, were used to analyze data using nonlinear mixed effect modeling (NONMEM).

RESULTS

For SGLT-2 inhibitors, canagliflozin, empagliflozin, ertugliflozin, ipragliflozin, luseogliflozin and tofogliflozin, the E _max, and treatment duration to reach half of the maximal effects (ET₅₀) were -3.72% and 3.35 weeks, -5.59% and 16.8 weeks, -2.84% and 3.42 weeks, -3.43% and 3.09 weeks, -3.04% and 4.38 weeks, and -2.45% and 3.16 weeks, respectively. In addition, for T2DM patients, 100 mg/day canagliflozin needs to be taken 13.4 weeks for the plateau of effect on weight; 10 mg/day empagliflozin needs to be taken 67.2 weeks for the plateau of effect on weight; 5 mg/day ertugliflozin needs to be taken 13.68 weeks for the plateau of effect on weight; 50 mg/day ipragliflozin needs to be taken 12.36 weeks for the plateau of effect on weight; 2.5 mg/day luseogliflozin needs to be taken 17.52 weeks for the plateau of effect on weight; 20 mg/day tofogliflozin needs to be taken 12.64 weeks for the plateau of effect on weight.

CONCLUSIONS

This was the first study to explore effects of SGLT-2 inhibitors on weight in T2DM; meanwhile, the optimum dosages and treatment durations on weight from canagliflozin, empagliflozin, ertugliflozin, ipragliflozin, luseogliflozin, and tofogliflozin were recommended, respectively.

Management of Hyperglycemia in Older Adults with Type 2 Diabetes

The increasing incidence of type 2 diabetes in the general population as well as enhanced life expectancy has resulted in a rapid rise in the prevalence of diabetes in the older population. Diabetes causes significant morbidity and impairs quality of life. Managing diabetes in older adults is a daunting task due to unique health and psychosocial challenges. Medical management is complicated by polypharmacy, cognitive impairment, urinary incontinence, injurious falls, and persistent pain. Health care providers now have several traditional and contemporary pharmacologic agents to manage diabetes. Avoidance of hypoglycemia is critical; however, evidence-based guidelines are lacking due to the paucity of clinical trials in older adults. For many in this population, maintaining independence is more important than adherence to published guidelines to prevent diabetes complications. The goal of diabetes care in older adults is to enhance the quality of life without subjecting these patients to intrusive and complicated interventions. Recent technological advancements such as continuous glucose monitoring systems can have crucial supplementary benefits in the geriatric population.

Potential contribution of haemoconcentration to changes in lipid variables with empagliflozin in patients with type 2 diabetes: A post hoc analysis of pooled data from four phase 3 randomized clinical trials

AIM

To examine the association between changes in lipids and markers of haemoconcentration (haematocrit and serum albumin) with empagliflozin, a sodium-glucose co-transporter-2 inhibitor, in patients with type 2 diabetes (T2D) using pooled data from four phase 3 randomized trials.

Patients with T2D received placebo (n = 825), empagliflozin 10 mg (n = 830) or 25 mg (n = 822) for 24 weeks. In post hoc mediation analyses, we assessed total changes in LDL-cholesterol, HDL-cholesterol, triglycerides, apolipoprotein (Apo) B, and Apo A-I, and changes in these variables associated with, and independent of, changes in haematocrit and serum albumin at week 24 using ANCOVA models.

RESULTS

Empagliflozin versus placebo increased serum LDL-cholesterol, HDL-cholesterol, and Apo A-I, decreased triglycerides (empagliflozin 10 mg only), and (non-significantly) increased Apo B. Empagliflozin modestly increased haematocrit and serum albumin. In mediation analyses, haematocrit changes (increases) with empagliflozin were associated with significant changes (increases) in all lipid variables, including Apo B. Except for triglycerides (non-significant), similar lipid variable associations were observed with serum albumin changes. Haematocrit- and serum albumin-independent changes in lipids with empagliflozin were significant for HDL-cholesterol (increases), mostly significant for triglycerides (decreases), and less so for other lipid fractions.

CONCLUSION

Haematocrit and serum albumin increases were associated with increases in lipid fractions with empagliflozin. Empagliflozin-associated changes in serum lipids, particularly LDL-cholesterol increases, may be partly attributable to haemoconcentration resulting from increased urinary volume and subsequent volume contraction.

Empagliflozin Induces White Adipocyte Browning and Modulates Mitochondrial Dynamics in KK Cg-Ay/J Mice and Mouse Adipocytes

Background: White adipose tissue (WAT) browning is a promising target for obesity prevention and treatment. Empagliflozin has emerged as an agent with weight-loss potential in clinical and in vivo studies, but the mechanisms underlying its effect are not fully understood. Here, we investigated whether empagliflozin could induce WAT browning and mitochondrial alterations in KK Cg-Ay/J (KKAy) mice, and explored the mechanisms of its effects.

Methods: Eight-week-old male KKAy mice were administered empagliflozin or saline for 8 weeks and compared with control C57BL/6J mice. Mature 3T3-L1 adipocytes were treated in the presence or absence of empagliflozin. Mitochondrial biosynthesis, dynamics, and function were evaluated by gene expression analyses, fluorescence microscopy, and enzymatic assays. The roles of adenosine monophosphate–activated protein kinase (AMPK) and peroxisome proliferator–activated receptor-γ coactivator-1-alpha (PGC-1α) were determined through AICAR (5-Aminoimidazole-4-carboxamide1-β-D-ribofuranoside)/Compound C and RNA interference, respectively.

Results: Empagliflozin substantially reduced the bodyweight of KKAy mice. Mice treated with empagliflozin exhibited elevated cold-induced thermogenesis and higher expression levels of uncoupling protein 1 (UCP1) and other brown adipose tissue signature proteins in epididymal and perirenal WAT, which was an indication of browning in these WAT depots. At the same time, empagliflozin enhanced fusion protein mitofusin 2 (MFN2) expression, while decreasing the levels of the fission marker phosphorylated dynamin-related protein 1 (Ser616) [p-DRP1 (Ser616)] in epididymal and perirenal WAT. Empagliflozin also increased mitochondrial biogenesis and fusion, improved mitochondrial integrity and function, and promoted browning of 3T3-L1 adipocytes. Further, we found that AMPK signaling activity played an indispensable role in empagliflozin-induced browning and mitochondrial biogenesis, and that PGC-1α was required for empagliflozin-induced fusion. Whether empagliflozin activates AMPK by inhibition of SGLT2 or by independent mechanisms remains to be tested.

Conclusion: Our results suggest that empagliflozin is a promising anti-obesity treatment, which can immediately induce WAT browning mitochondrial biogenesis, and regulate mitochondrial dynamics.

Sodium-glucose cotransporter 2 inhibitors for the management of type 2 diabetes

INTRODUCTION

Sodium-glucose cotransporter (SGLT) 2 inhibitors reduce glucose reabsorption in the kidney, increase glucosuria, and improve glycemia. Besides glycemic efficacy, the class also lowers risk of cardiovascular and renal disease.

AREAS COVERED

The authors describe late phase trials of empagliflozin, canagliflozin, dapagliflozin, and ertugliflozin. Safety and efficacy endpoints in monotherapy, combination therapy, cardiovascular, and renal outcomes trials have been identified and presented.

EXPERT OPINION

SGLT2 inhibitors appear to be safe and effective agents that improve glycemia when used alone or in combination with any other approved antihyperglycemic medications. Other beneficial effects include reductions in body weight and blood pressure, improvements in renal outcomes, all-cause mortality, cardiovascular mortality, and worsening heart failure.

Effect of sodium-glucose cotransporter 2 inhibitors on hemoglobin and hematocrit levels in type 2 diabetes: a systematic review and meta-analysis

BACKGROUND

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) improve outcomes of patients with type 2 diabetes at high cardiovascular risk and chronic kidney disease. Recent studies showed an increase in hemoglobin and hematocrit after SGLT2i treatment.

MATERIALS AND METHODS

We did a systematic review and meta-analysis of randomized, double-blind, placebo-controlled studies of SGLT2i in patients with type 2 diabetes. We searched through PubMed/Medline, Web of Science, Embase (Elsevier), and the Cochrane Central Register of Controlled Trials (Wiley) from January 2010 to January 2021.

RESULTS

We included seventeen randomized, double-blind, placebo-controlled studies. The total number of evaluated patients was 14,748. The treatment arm consisted of canagliflozin, dapagliflozin, empagliflozin and ipragliflozin. SGLT2i therapy significantly increased hemoglobin levels when compared to placebo (MD 5.60 g/L, 95% CI 3.73-7.47 g/L, P < 0.00001, considerable heterogeneity-I² = 94%). Each SGLT2i also led to a significant increase in the hematocrit level when compared to placebo (MD 1.32%, 95% CI 1.21-1.44, P < 0.00001, considerable heterogeneity-I² = 99%).

CONCLUSIONS

SGLT2i led to significant increases in hemoglobin and hematocrit levels when compared to placebo. In addition to their cardiovascular effect, SGLT2i also increases hemoglobin and hematocrit levels.

Combined medical strategies for the management of type 2 diabetes mellitus and obesity in adults

INTRODUCTION

Given the relationship between the pathogenesis of obesity and type 2 diabetes mellitus (T2DM) as well as their significant health consequences, treatment strategies that can induce weight loss while achieving glycemic control are needed. Novel weight-reducing anti-diabetic agents along with anti-obesity medications (AOMs) can help medical providers address both conditions simultaneously and effectively.

AREAS COVERED

This review summarizes and compares weight loss efficacy and glycemic control of weight-reducing anti-diabetic medications, AOMs and emerging pharmacologic agents that help treat both obesity and T2DM.

EXPERT OPINION

Management of obesity and T2DM can be challenging to achieve and sustain in the presence of obesogenic anti-diabetic agents. Utilizing weight-reducing anti-diabetic agents, AOMs, and endobariatric or surgical procedures, either separately or in combination, can help achieve better clinical outcomes in patients with obesity and T2DM. Some agents in development, such as tirzepatide and bimagrumab, are promising pharmacotherapy options that may change the standards of care for cardiometabolic disease management.

Efficacy and Safety of Ertugliflozin in Patients with Type 2 Diabetes Inadequately Controlled by Metformin and Sulfonylurea: A Sub-Study of VERTIS CV

INTRODUCTION

VERTIS CV is the cardiovascular outcome trial for the sodium-glucose cotransporter 2 (SGLT2) inhibitor ertugliflozin. A sub-study was conducted to assess the efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus (T2DM) inadequately glycemic-controlled on metformin and a sulfonylurea (SU).

METHODS

Patients with T2DM, established atherosclerotic cardiovascular disease (ASCVD), and an HbA1c of 7.0-10.5% on stable metformin (≥ 1500 mg/day) and moderate to high SU doses were randomly assigned to once-daily ertugliflozin (5 or 15 mg) or placebo. The primary sub-study objectives were to assess the effect of ertugliflozin on HbA1c compared with placebo and to evaluate safety following 18 weeks of treatment. Key secondary endpoints included changes in fasting plasma glucose (FPG), body weight (BW), blood pressure (BP), and the proportion of patients achieving HbA1c < 7%.

RESULTS

Of the 8246 patients enrolled in VERTIS CV, 330 were eligible for this sub-study (ertugliflozin 5 mg, n = 100; ertugliflozin 15 mg, n = 113; placebo, n = 117). This subgroup had a mean (SD) age of 63.2 (8.4) years and T2DM duration of 11.4 (7.4) years. At week 18, ertugliflozin 5 mg and 15 mg were each associated with significantly greater least squares (LS) mean reductions from baseline in HbA1c relative to placebo (placebo-adjusted LS mean [95% CI] - 0.66% [- 0.89, - 0.43] and - 0.75% [- 0.98, - 0.53], respectively, p < 0.001 for each dose vs placebo). Ertugliflozin significantly reduced FPG and BW compared with placebo (p < 0.001), but not systolic BP. Adverse events were reported in 48.0%, 54.9%, and 47.0% of patients in the ertugliflozin 5 mg and 15 mg, and placebo groups. The incidences of symptomatic hypoglycemia were 11.0% (5 mg), 12.4% (15 mg), and 7.7% (placebo), and of severe hypoglycemia 2.0% (5 mg), 1.8% (15 mg), and 0.9% (placebo).

CONCLUSIONS

In patients with T2DM and ASCVD, ertugliflozin added to metformin and SU improved glycemic control, reduced BW, and was generally well tolerated.

Eligibility for dapagliflozin in unselected patients hospitalised with decompensated heart failure

Patients with heart failure with reduced ejection fraction (HFrEF) who received the sodium-glucose co-transport 2 inhibitor, dapagliflozin, in the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) study have a significant reduction in worsening heart failure (HF) and cardiovascular death. It is uncertain what proportion of patients admitted to a large regional cardiac centre with decompensated heart failure would be eligible for dapagliflozin post-discharge based on their characteristics at discharge. The DAPA-HF study criteria were retrospectively applied to a cohort of 521 consecutive patients referred to the inpatient HF service in a tertiary cardiac centre in South West Wales between April 2017 and April 2018. Inclusion criteria: left ventricular ejection fraction (LVEF) < 40%, New York Heart Association (NYHA) class II-IV symptoms and an elevated N-terminal pro-B-type naturietic peptide (NT-proBNP). Exclusion criteria: systolic blood pressure (SBP) < 95 mmHg, estimated glomerular filtration rate (eGFR) < 30 ml/min/1.73 m2 or type 1 diabetes mellitus. We did not have complete NTproBNP data for the cohort, as it was not routinely measured at the time in our institute. There were 478 patients, mean age 78 ± 13 years, 57% male and 91% NYHA class II-IV symptoms, were included in the analysis. Of these, 247 patients had HFrEF, 219 (46%) patients met the inclusion criteria, 231 (48%) were excluded as LVEF was > 40%, and 48 (10%) were excluded with NYHA class I symptoms. Of the 219 patients who met the inclusion criteria, 13 (5.9%) had a SBP < 95 mmHg, 48 (22%) had eGFR < 30 ml/min/1.73 m2, leaving 136 (28.5% of total and 55% of those with HFrEF) who met DAPA-HF study criteria. In our study, 28.5% of all heart failure admissions and 55% of patients with HFrEF would be eligible for dapagliflozin post-discharge according to the DAPA-HF study entry criteria.

Towards Better Drug Repositioning: Targeted Immunoinflammatory Therapy for Diabetic Nephropathy

Diabetic nephropathy (DN) is one of the most common and important microvascular complications of diabetes mellitus (DM). The main clinical features of DN are proteinuria and a progressive decline in renal function, which are associated with structural and functional changes in the kidney. The pathogenesis of DN is multifactorial, including genetic, metabolic, and haemodynamic factors, which can trigger a sequence of events. Controlling metabolic risks such as hyperglycaemia, hypertension, and dyslipidaemia is not enough to slow the progression of DN. Recent studies emphasized immunoinflammation as a critical pathogenic factor in the progression of DN. Therefore, targeting inflammation is considered a potential and novel treatment strategy for DN. In this review, we will briefly introduce the inflammatory process of DN and discuss the anti-inflammatory effects of antidiabetic drugs when treating DN.

Association of SGLT2 inhibitors with arrhythmias and sudden cardiac death in patients with type 2 diabetes or heart failure: A meta-analysis of 34 randomized controlled trials

BACKGROUND

Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reduce hospitalizations and death from heart failure (HF), but their effect on arrhythmia expression has been poorly investigated.

OBJECTIVE

The purpose of this study was to evaluate the association of SGLT2is with arrhythmias in patients with type 2 diabetes mellitus (T2DM) or HF.

METHODS

We searched PubMed and ClinicalTrials.gov. Two independent investigators identified randomized double-blind trials that compared SGLT2is with placebo or active control for adults with T2DM or HF. Primary outcomes were incident atrial arrhythmias, ventricular arrhythmias (VAs), and sudden cardiac death (SCD).

RESULTS

We included 34 randomized (25 placebo-controlled and 9 active-controlled) trials with 63,166 patients (35,883 SGLT2is vs 27,273 control: mean age 53-67 years; 63% male). Medications included canagliflozin, dapagliflozin, empagliflozin, or ertugliflozin. Except for 1 study of HF, all patients had T2DM. Follow-up ranged from 24 weeks to 5.7 years. The cumulative incidence of events was low: 3.6, 1.4, and 2.5 per 1000 patient-years for atrial arrhythmias, VAs and SCD, respectively. SGLT2i therapy was associated with a significant reduction in the risk of incident atrial arrhythmias (odds ratio 0.81; 95% confidence interval 0.69-0.95; P = .008) and the "SCD" component of the SCD outcome (odds ratio 0.72; 95% confidence interval 0.54-0.97; P = .03) compared with control. There was no significant difference in incident VA or the "cardiac arrest" SCD component between groups.

CONCLUSION

SGLT2is are associated with significantly reduced risks of incident atrial arrhythmias and SCD in patients with T2DM. Prospective trials are warranted to confirm the antiarrhythmic effect of SGLT2is and whether this is a class or drug-specific effect.

Thymoquinone with Metformin Decreases Fasting, Post Prandial Glucose, and HbA1c in Type 2 Diabetic Patients

OBJECTIVE

Antihyperglycemic activity of Thymoquinone (TQ) was evaluated in diabetic mouse model and patients.

METHODS

TQ (50 mg/kg) was orally administered daily for 21 days in combination with metformin in diabetic mice and a reduction on blood glucose level was monitored. In human, a 90-day randomized study was carried out in 60 Type 2 Diabetes mellitus patients to evaluate safety and efficacy of TQ administration with metformin in a 3-arm study. Patients in arm 1 (T1) received 1 tablet of metformin SR 1000 mg and 1 tablet of TQ 50 mg once daily. The second arm (T2) patients received 1 tablet of metformin SR 1000 mg and 2 tablets of TQ 50 mg once daily. Patients in arm 3 (R) received 1 tablet of metformin SR 1000 mg only.

RESULTS

The diabetic mice treated with combination of TQ and metformin showed significant decrease in blood sugar compared to those treated with only metformin. In patients who completed the study, the glycated hemoglobin (HbA1c) values in T1, T2 and R decreased after 3 months from 7.2, 7.2 and 7.3 to 6.7, 6.8, and 7.1, respectively. A greater reduction in Fasting Blood Glucose and Post Prandial Blood Glucose was also observed in T1 and T2 arms compared to R.

CONCLUSION

At dose levels of 50 and 100 mg of TQ combined with a daily dose of 1000 mg Metformin demonstrated a reduction in the levels of HbA1c and blood glucose compared to the standard treatment of diabetic patients with metformin alone.

Does SGLT2 Inhibition Affect Sympathetic Nerve Activity in Type 2 Diabetes?

SGLT2 inhibitors increase renal glucose excretion and thus decrease both fasting and postprandial plasma glucose levels. The effects of SGLT2 inhibition outweigh those on glycemic control and are also associated with the induction of hemodynamic changes that improve cardiovascular and renal function in people with type 2 diabetes. The exact mechanisms have not yet been completely clarified. This review is focused on the potential relationship between SGLT2 inhibition and sympathetic nerve activity. There is accumulating evidence for a suppressive effect of SGLT2 inhibitors on the sympathetic nerve tone, which might be a putative mechanism for cardiovascular protection in subjects with type 2 diabetes.

Pancreatic safety of sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes mellitus: A systematic review and meta-analysis

PURPOSE

This study aimed to systematically evaluate the association between sodium-glucose cotransporter 2 (SGLT2) inhibitors and pancreatic safety in patients with type 2 diabetes mellitus (T2DM).

METHODS

Electronic databases were searched before September 2019 to include randomized controlled trials (RCTs) of SGLT2 inhibitors that reported any event on pancreatitis or pancreatic cancer among patients with T2DM. Peto odds ratio (OR) with 95% confidence interval (CI) was used to pool the data. The GRADE framework was introduced to assess the quality of evidence.

RESULTS

Of the 35 trials involving 44 912 patients with T2DM included, 41 events of acute pancreatitis (19 trials; 32 932 patients), 72 events of overall pancreatitis (including acute pancreatitis, chronic pancreatitis, or nonspecific pancreatitis; 26 trials; 36 688 patients), and 40 events of pancreatic cancer (18 trials; 27 806 patients) were reported during a median follow-up of 52 weeks. SGLT2 inhibitors were not associated with an increased risk of acute pancreatitis compared to controls (placebo or other active drugs; Peto OR, 1.13; 95% CI, 0.60-2.13; moderate quality evidence). A similar result was found for risk of overall pancreatitis (Peto OR, 1.08; 95% CI, 0.67-1.75; moderate quality evidence) and pancreatic cancer (Peto OR, 1.34; 95% CI, 0.71-2.54; very low-quality evidence).

CONCLUSIONS

Moderate quality evidence from RCTs shows no significantly increased risk of acute pancreatitis associated with SGLT2 inhibitors, while there is very low-quality evidence suggesting no significant association between SGLT2 inhibitors and pancreatic cancer among patients with T2DM.

Adding Sodium-Glucose Co-Transporter 2 Inhibitors to Sulfonylureas and Risk of Hypoglycemia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Hypoglycemia is an important event that could be related to increased mortality in patients with diabetes. The risk of hypoglycemia is not clearly illustrated to increase when Sodiumglucose co-transporter 2 (SGLT-2) inhibitors are used concomitantly with sulfonylureas. The present study will assess the risk of hypoglycemia associated with the concomitant use of SGLT-2 inhibitors and sulfonylureas compared with placebo and sulfonylureas.

METHOD

We searched Medline, EMBASE, Cochrane Central Register of Controlled Trials, and Clinicaltrial.gov and identified the randomized trials comparing SGLT-2 inhibitors with placebo for type 2 diabetes treated with sulfonylureas. The risk of bias in each trial was assessed using the Cochrane tool. The risk ratio of hypoglycemia was measured using the Mantel Haenszel method. We also performed subgroup analysis to examine the dosage effects. The number needed to harm (NNH) was measured according to the duration of intervention.

RESULTS

A total of 12 studies, including 3761 participants, were enrolled in our systematic review and meta-analysis. The risk ratio of hypoglycemia was 1.67 (95% CI 1.42 to 1.97). The NNH was 13 (95% CI 9 to 21) for a treatment duration of 24 weeks or less, 11 (8 to 18) for 25 to 48 weeks, and 7 (5 to 10) for more than 48 weeks. Subgroup analysis showed that no difference was found between higher and lower doses of SGLT-2 inhibitors. The risk ratio related to lower dose SGLT-2 inhibitors was 1.56 (95% CI 1.30 to 1.88), and the risk ratio related to higher dose SGLT-2 inhibitors was 1.70 (95% CI 1.42 to 2.04).

CONCLUSIONS

The risk of hypoglycemia was significantly increased in subjects treated with SGLT-2 inhibitors compared with placebo. Addition of SGLT-2 inhibitors to sulfonylureas would lead to one more case of hypoglycemia in every 13 patients with a treatment duration less than 24 weeks. This suggests that a decrease in sulfonylureas dose may be an important recommendation when adding SGLT-2 inhibitors to sulfonylureas.

The Impact of Empagliflozin on Obstructive Sleep Apnea and Cardiovascular and Renal Outcomes: An Exploratory Analysis of the EMPA-REG OUTCOME Trial

OBJECTIVE

To explore the effects of empagliflozin on the incidence of obstructive sleep apnea (OSA) and its effects on metabolic, cardiovascular (CV), and renal outcomes among participants with or without OSA in the EMPA-REG OUTCOME trial.

RESEARCH DESIGN AND METHODS

Participants with diabetes and CV disease were randomized to empagliflozin (10 and 25 mg) or placebo daily in addition to standard of care. OSA was assessed by investigator report using Medical Dictionary for Regulatory Activities version 18.0, and CV outcomes were independently adjudicated. Analyses were performed using multivariable-adjusted Cox regression models.

RESULTS

OSA was reported in 391 of 7,020 (5.6%) participants at baseline. Those with OSA were more likely to be male (83% vs. 71%) and to have moderate to severe obesity (BMI ≥35 kg/m²; 55% vs. 18%). Over a median of 3.1 years, empagliflozin had similar placebo-adjusted reductions in HbA_1c, waist circumference, and systolic blood pressure, regardless of OSA status, but a larger effect on weight (adjusted mean ± SE difference at week 52: OSA vs. no OSA -2.9 ± 0.5 vs. -1.9 ± 0.1 kg). Incidence of 3-point major adverse CV events, CV death, heart failure hospitalization, and incident or worsening nephropathy in the placebo group was 1.2- to 2.0-fold higher for those with baseline OSA compared with those without. Empagliflozin significantly reduced the risk for outcomes regardless of OSA status (P-interaction all >0.05). Fifty patients reported a new diagnosis of OSA through 7 days after medication discontinuation, and this occurred less often with empagliflozin treatment (hazard ratio 0.48 [95% CI 0.27, 0.83]).

CONCLUSIONS

In EMPA-REG OUTCOME, participants with OSA had greater comorbidity and higher frequency of CV and renal events. Empagliflozin had favorable effects on risk factors and CV and renal outcomes regardless of preexisting OSA and may also reduce the risk for new-onset OSA.

Adipose Tissue Immunomodulation: A Novel Therapeutic Approach in Cardiovascular and Metabolic Diseases

Adipose tissue is a critical regulator of systemic metabolism and bodily homeostasis as it secretes a myriad of adipokines, including inflammatory and anti-inflammatory cytokines. As the main storage pool of lipids, subcutaneous and visceral adipose tissues undergo marked hypertrophy and hyperplasia in response to nutritional excess leading to hypoxia, adipokine dysregulation, and subsequent low-grade inflammation that is characterized by increased infiltration and activation of innate and adaptive immune cells. The specific localization, physiology, susceptibility to inflammation and the heterogeneity of the inflammatory cell population of each adipose depot are unique and thus dictate the possible complications of adipose tissue chronic inflammation. Several lines of evidence link visceral and particularly perivascular, pericardial, and perirenal adipose tissue inflammation to the development of metabolic syndrome, insulin resistance, type 2 diabetes and cardiovascular diseases. In addition to the implication of the immune system in the regulation of adipose tissue function, adipose tissue immune components are pivotal in detrimental or otherwise favorable adipose tissue remodeling and thermogenesis. Adipose tissue resident and infiltrating immune cells undergo metabolic and morphological adaptation based on the systemic energy status and thus a better comprehension of the metabolic regulation of immune cells in adipose tissues is pivotal to address complications of chronic adipose tissue inflammation. In this review, we discuss the role of adipose innate and adaptive immune cells across various physiological and pathophysiological states that pertain to the development or progression of cardiovascular diseases associated with metabolic disorders. Understanding such mechanisms allows for the exploitation of the adipose tissue-immune system crosstalk, exploring how the adipose immune system might be targeted as a strategy to treat cardiovascular derangements associated with metabolic dysfunctions.
