Cardiovascular and Renal Outcomes with Efpeglenatide in Type 2 Diabetes

Beyond glycemic control: Roles for sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists in diabetic kidney disease

The global prevalence of diabetes has surged in recent years, with diabetic kidney disease (DKD) emerging as a major complication. Traditional therapies have had limited success in slowing progression to end-stage kidney disease. However, novel therapies, particularly sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists, which were initially developed for hyperglycemia management, have transformed the treatment of obesity, heart failure, cardiovascular disease, and more recently, DKD. SGLT2 inhibitors have consistently and significantly reduced cardiovascular events, albuminuria, and glomerular filtration rate, highlighting their efficacy across diverse clinical presentations for patients with kidney impairment. Although fewer studies have specifically investigated GLP-1 receptor agonists in patients with kidney disease, existing evidence underscores their potential to slow renal disease progression, reduce albuminuria, and improve clinically relevant outcomes. However, further research is needed to better identify patients most likely to benefit from treatment. Together, these therapies represent valuable advancements for DKD, offering significant reductions in morbidity and mortality and shifting the management of the disease by becoming essential pillars for the treatment of these patients.

Oral Semaglutide and Cardiovascular Outcomes in People With Type 2 Diabetes, According to SGLT2i Use: Prespecified Analyses of the SOUL Randomized Trial

BACKGROUND

Both GLP-1 (glucagon-like peptide-1) receptor agonists and SGLT2 (sodium-glucose cotransporter-2) inhibitors (SGLT2i) improve cardiovascular outcomes in people with type 2 diabetes and cardiovascular or chronic kidney disease. However, there are limited data about the effect of combining these agents on cardiovascular and safety outcomes.

METHODS

The SOUL trial (Semaglutide Cardiovascular Outcomes Trial; NCT03914326) randomized 9650 participants with type 2 diabetes and atherosclerotic cardiovascular disease and/or chronic kidney disease to oral semaglutide or placebo. As prespecified, participants were analyzed according to baseline use of SGLT2i (yes, n=2596; no, n=7054), and subsequently for any use of SGLT2i during the trial (yes, n=4718; no, n=4932). The primary outcome was time to first major adverse cardiovascular event, defined as cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Safety was evaluated by comparing the incidence of serious adverse events.

RESULTS

Over a mean follow-up of 47.5±10.9 months, the risk of the primary outcome in the overall trial population was 14% lower for oral semaglutide versus placebo (hazard ratio, 0.86; 95% CI, 0.77-0.96). In those taking SGLT2i at baseline, there were 143 of 1296 (semaglutide) versus 158 of 1300 (placebo) primary outcome events (hazard ratio, 0.89; 95% CI, 0.71-1.11); and 436 of 3529 versus 510 of 3525, respectively, in participants not taking SGLT2i at baseline (hazard ratio, 0.84; 95% CI, 0.74-0.95; P-interaction, 0.66). An analysis of major adverse cardiovascular events by any in-trial SGLT2i use versus no use also showed no evidence of heterogeneity in the effects of oral semaglutide. The adverse event profiles of oral semaglutide with or without concomitant SGLT2i were similar.

CONCLUSIONS

Oral semaglutide reduced major adverse cardiovascular event outcomes independently of concomitant SGLT2i treatment, and this combination appeared to be safe.

Semaglutide, central retinal thickness and continuous glucose monitoring in persons with type 2 diabetes: A post-hoc analysis from a randomised trial

AIMS

Glycemic control is important for preventing diabetic retinopathy (DR), but rapid improvements could deteriorate the disease. In some, but not all studies, semaglutide is speculated to worsen DR, but the mechanism is unknown. Central retinal thickness (CRT) is an early marker of DR. Therefore, the objective was to investigate whether increased Time in Range (TIR (3.9-10.0 mmol/L)), was associated with reduced CRT in persons treated with semaglutide.

METHODS

Forty participants with type 2 diabetes were included in this post-hoc analysis of a 32-week randomised, placebo-controlled, partly open-label trial investigating the separate and combined effects of semaglutide and empagliflozin on target organ damage in 120 participants with type 2 diabetes. Individuals were randomised into four groups: i) semaglutide, ii) empagliflozin, iii) the combination or iv) placebo, n = 30 for each group). In the present study, 10 participants from each of the 4 arms participated. TIR was assessed using Continuous Glucose Measurement for 7-8 days and CRT was assessed using ocular coherence tomography.

RESULTS

In the 10 individuals treated with semaglutide, CRT increased ~1 % (3.76 μm, 95%CI [-0.32; 7.85], p = 0.065) compared to placebo. This was attenuated with adjustment for TIR (p = 0.21). Independently of the four interventions, increased TIR remained associated with increased CRT (0.07 μm, 95%CI[0.03; 0.12]μm, p = 0.002).

CONCLUSION

Semaglutide treatment did not impact CRT beyond what could be explained by changes in glycaemia. Across all interventions, increased TIR was associated with increases in CRT, thus supporting the link between rapid improved glycemia and DR.

Cardiovascular-Kidney-Metabolic (CKM) Syndrome: A Case-Based Narrative Review

These 4 hypothetical cases highlight new features of the American Heart Association cardiovascular-kidney-metabolic (CKM) health construct. The cases incorporate the CKM staging system, estimates from the PREVENT risk calculator, and clinical approaches related to CKM stages and individual risk profiles. Topics include management considerations for (1) a patient with stage 1 obesity and impaired glucose tolerance, (2) a patient with metabolic risk factors and moderate-risk chronic kidney disease (CKD), (3) a patient with subclinical atherosclerotic cardiovascular disease and multiple comorbid conditions, and (4) a patient with metabolic risk factors, prior myocardial infarction, new-onset heart failure, atrial fibrillation, and CKD.

Guideline-Recommended Disease-Modifying Therapies for Patients with Cardiorenal Disease: A Call-to-Action Narrative Review

Substantial gaps exist between recommendations for guideline-directed medical therapy (GDMT) for chronic kidney disease (CKD) and its use in real-world clinical practice. This includes suboptimal dosing of renin-angiotensin system inhibitors (RASi), low uptake of sodium-glucose co-transporter 2 inhibitors (SGLT2i) for CKD, and low uptake and/or transient use of potassium binders to manage RASi-induced hyperkalemia. Suboptimal RASi therapy deprives patients of the full cardiorenal benefits associated with RASi, and increases the risk of cardiorenal adverse events and mortality. Hyperkalemia can be managed and optimal RASi dosing can be continued by using novel potassium binders, such as sodium zirconium cyclosilicate or patiromer. Similarly, low uptake of SGLT2i might be associated with the concern of an accelerated decline in estimated glomerular filtration rate and, therefore, disease progression when initiating SGLT2i. Numerous clinical trials have demonstrated that adding SGLT2i to RASi therapy can improve clinical outcomes and prolong patient survival in CKD. The recently published Kidney Disease: Improving Global Outcomes (KDIGO) 2024 clinical practice guideline for the evaluation and management of CKD extends the recommendation of SGLT2i to individuals with CKD without diabetes, reinforces the cardiorenal benefits of optimized RASi, recommends the addition of newer drug classes in suitable patients with CKD, and notes the use of novel potassium binders to manage hyperkalemia and enable optimal use of GDMT. In doing so, the guideline targets achievement of the "quadruple aim" of GDMT in CKD, i.e., enabling optimal use of RASi and SGLT2i in most patients, along with nonsteroidal mineralocorticoid receptor antagonists, and glucagon-like peptide-1 receptor agonists in diabetic kidney disease. This manuscript constitutes a call to action to raise awareness of the growing clinical and economic burdens of CKD and to promote a united approach to the early detection and optimal treatment of CKD through stricter adherence to GDMT.

Refining the link between obesity and heart failure: insights from GLP-1 receptor agonist trials and studies adopting direct adiposity measures

Overweight and obesity are major risk factors for heart failure (HF), contributing to its development through metabolic, neurohormonal, haemodynamic, and inflammatory alterations. While overweight/obesity increases the risk of developing HF, its impact on patient outcomes remains complex. The "obesity paradox" suggests that a higher BMI may be associated with improved survival in patients with established HF. However, recent GLP-1 receptor agonist (GLP-1 RA) trials suggest that intentional weight loss positively influences outcomes in overweight/obese patients with HF. This seemingly contradictory evidence highlights the need for a deeper understanding of the mechanisms linking adiposity to HF outcomes. A more precise characterization of adiposity phenotypes using alternative and accurate measures of pathological fat accumulation is crucial in identifying individuals who may benefit most from anti-obesity treatments. In this context, recent research underscores the role of epicardial adipose tissue (EAT) in HF pathophysiology, as it directly influences cardiac function and structure through inflammatory, metabolic, and mechanical effects. This narrative review summarises current evidence on the impact of weight loss on HF outcomes, focusing on recent GLP-1 RA trial results. Additionally, it highlights epidemiological and molecular data supporting EAT as a novel adiposity measure that might allow refining patient selection for pharmacological weight-loss treatments. Finally, it emphasizes the need for future research to identify causal pathways linking alternative measures of visceral fat accumulation to HF outcomes. These efforts will be essential in optimizing the benefits of novel weight-loss treatments, ensuring effective and individualized therapeutic strategies for overweight or obese patients with HF.

The effect of GLP-1 receptor agonists on cardiac remodeling in heart failure patients with preserved and reduced ejection fraction: a systematic review and meta-analysis

BACKGROUND

Glucagon-like peptide-1 receptor agonists (GLP-1RA) have shown promising effects on heart failure (HF) outcomes, particularly in phenotype-specific populations. However, their impact on cardiac structure and function in HF with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF) remains unclear.

METHODS

Medline, Cochrane Library, and Scopus were queried through December 2024 for primary and secondary analyses of randomized controlled trials comparing GLP-1RA with placebo in HF patients. Outcomes included changes in left ventricular ejection fraction (LVEF), end-diastolic volume (LVEDV), end-systolic volume (LVESV), global longitudinal strain (GLS), left ventricular mass, left atrial volume (LAV), and NT-proBNP levels. Random-effects models were used to calculate weighted mean differences (WMDs) or hazard ratios (HRs).

RESULTS

Six trials (n = 1,195) were included, with three each evaluating HFpEF and HFrEF populations. In patients with HFpEF, GLP-1RA significantly reduced the LV mass (WMD: -8.6 g; 95% CI: -14.6, -2.6; p = 0.005) and LAV (WMD: -5.4 ml; 95% CI: -8.8, -2.0; p = 0.002) and lowered NT-proBNP concentration throughout (HR: 0.85; 95% CI: 0.8, 0.9; p < 0.001). A decrease in LAV was observed in the HFrEF population (WMD: -5.4 ml [95% CI: -8.8, -2.0]; p = 0.002). However, no significant improvements were observed in LVEF, LVEDV, LVESV, or GLS. There were significant differences between HFpEF and HFrEF for LVEDV (p = 0.01) and LVESV (p = 0.04).

CONCLUSIONS

GLP-1RA demonstrated phenotype-specific benefits, improving structural remodeling in HFpEF but showing limited effects in HFrEF. These findings highlight the importance of targeted therapeutic strategies based on HF phenotypes. Further research is warranted to elucidate underlying mechanisms and optimize patient selection.

Effects of GLP-1 receptor agonists on incidence and outcomes of ischemic stroke and myocardial infarction: A systematic review and meta-analysis

INTRODUCTION

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) demonstrate cardiovascular benefits beyond glycemic control, but the benefits of protection across cerebrovascular and cardiovascular territories remain incompletely studied in the literature. We aim to evaluate whether GLP-1 RAs provide balanced protection against stroke and myocardial infarction (MI) and identify factors that modify this protection.

METHODS

We conducted a systematic review and meta-analysis of randomised controlled trials comparing GLP-1 RAs with placebo that reported cerebrovascular and cardiovascular outcomes. We calculated hazard ratios (HRs) for stroke and MI and developed a novel Territorial Benefit Ratio (TBR = HR stroke/HR MI) to quantify relative cerebrovascular versus coronary protection. Meta-regression analyses identified factors modifying territorial protection.

RESULTS

Eleven trials with 85 373 participants met inclusion criteria. GLP-1 RAs significantly reduced stroke (HR 0.88, 95% CI 0.80-0.96) and MI (HR 0.87, 95% CI 0.79-0.97), resulting in an overall balanced TBR of 1.01 (95% CI 0.89-1.15). Protection patterns varied significantly by patient subgroups: prior stroke history provided better stroke protection (HR 0.73, NNT 54), while prior MI history provided better MI protection (HR 0.79, NNT 55). MI protection emerged earlier within the first six months (HR 0.81), while stroke protection strengthened over time (over 24 months: HR 0.80). Renal dysfunction, atrial fibrillation, and hypertension shifted protection towards stroke, while dyslipidemia provided better MI protection.

CONCLUSIONS

GLP-1 RAs demonstrate a protection-in-territory-at-risk pattern with important temporal findings and results translated. These findings support a personalised approach to GLP-1 RA therapy that considers patients' vascular history and risk profiles. The earlier emergence of MI protection and later strengthening of stroke protection deliver significant highlights for clinical expectations and treatment persistence.

Risk of Hearing Loss in Patients Treated with Exendin-4 Derivatives: A Network Meta-Analysis of Glucagon-like Peptide-1 Receptor Agonists and Sodium-Glucose Cotransporter 2 Inhibitors

Background/Objectives: Emerging evidence suggests an association between glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose co-transporter 2 (SGLT2) inhibitors with altered risk of damage in the inner ear system. However, limited research exists on the relationship between these medications and subsequent irreversible hearing loss. We conducted this network meta-analysis (NMA) to evaluate the comparative risk of hearing loss associated with such medications. Methods: In this NMA, we used a confirmatory approach to specifically focus on particular adverse effects of interest (i.e., incidence of hearing loss here) based on the Cochrane recommendation. A Bayesian-based NMA of randomized controlled trials (RCTs) of GLP-1 receptor agonists or SGLT2 inhibitors was conducted. The primary outcome was the hearing loss events. Results: Our NMA of 29 RCTs with 145,895 participants found that only two exendin-4 derivatives-lixisenatide and high-dose efpeglenatide (i.e., 6 mg/week)-showed increased hearing loss events compared to controls. No other GLP-1 receptor agonists or SGLT2 inhibitors demonstrated significantly elevated hearing loss risk. Lixisenatide ranked highest in risk among all investigated regimens. Conclusions: This comprehensive NMA identifies a significant association between exendin-4 derivatives (lixisenatide and efpeglenatide) and potential ototoxicity. Clinicians should carefully consider this potential ototoxicity when prescribing exendin-4 derivatives, particularly in patients with pre-existing hearing loss risk factors.

Impact of glp-1 receptor agonists on hospitalization for heart failure and all-cause death in patients with diabetes with and without heart failure: a real-world study

OBJECTIVE

Evidence on the impact of GLP-1 RAs on HF hospitalization (HHF) and mortality has been inconsistent across clinical trials in patients with diabetes. We investigated the association between GLP-1 RAs and these outcomes in a real-world setting.

METHODS

We selected individuals aged 45 years and older already treated with metformin living in Lombardy, Italy, and then split them into two groups if they initiated GLP-1 RAs or other antidiabetic drugs, between 2019 and 2021. A multivariable Cox proportional hazard regression model was performed to assess the association of GLP-1 RAs on HHF and all-cause death as hazard ratios (HRs) with 95% CI compared to the Other ADs group, stratifying by history of HF. The role of GLP-1 RAs was also investigated using the Inverse Probability Treatment Weighting (IPTW) and in the subgroup analyses.

RESULTS

In total, 9795 patients in the GLP-1 RAs group (302 with HF; 9493 without) and 6018 in the Other ADs group (405 with HF; 5613 without) were included in the analysis. GLP-1 RAs use was significantly associated with a lower risk of HHF in patients with a history of HF (HR 0.65; CI 95% 0.426-0.987) and in those without (HR 0.52; CI 95% 0.371-0.733). A lower risk for all-cause death was also observed in GLP-1 RAs users (with HF: HR 0.45; CI 95% 0.320-0.638; without HF: HR 0.44; CI 95% 0.383-0.514). The results of the IPTW and subgroup analyses confirmed those of the main analysis.

CONCLUSION

Our findings showed a benefit of GLP-1 RAs on HHF and all-cause death in patients with diabetes regardless of HF history. Although, our study presents several limitations, if confirmed through dedicated randomized trial, this could further expand the role of GLP-1RAs in cardiovascular prevention".

Role of Residual Inflammation as a Risk Factor Across Cardiovascular-Kidney-Metabolic (CKM) Syndrome: Unpacking the Burden in People with Type 2 Diabetes

Type 2 diabetes mellitus (T2DM) is a global health crisis, with cardiovascular disease (CVD) accounting for 75% of mortality in this population. Despite advances in managing traditional risk factors, such as low-density lipoprotein cholesterol (LDL) cholesterol reduction (IMPROVE-IT, FOURIER), antithrombotic therapies (PEGASUS, COMPASS), and triglyceride-lowering agents (REDUCE-IT), a substantial residual cardiovascular risk persists, driven in part by chronic low-grade systemic inflammation. Chronic low-grade inflammation is a central driver of cardiovascular-kidney-metabolic (CKM) syndrome in T2DM, perpetuating residual cardiovascular risk despite optimal management of traditional risk factors. This narrative review synthesizes evidence on how inflammation accelerates coronary heart disease (CHD), heart failure (HF), stroke, diabetic kidney disease (DKD), and peripheral artery disease (PAD). We evaluate the anti-inflammatory mechanisms of current therapies such as statins, sodium-glucose cotransporter 2 (SGLT2) inhibitors, and glucagon-like peptide 1 (GLP-1) receptor agonists, as well as emerging agents like colchicine and interleukin (IL)-1β/IL-6 inhibitors, emphasizing their differential efficacy across CKM traits. By integrating pathophysiological insights with clinical trial data, we propose biomarker-guided strategies to target inflammation as a modifiable risk factor, offering a roadmap to bridge the gap in diabetes-related cardiovascular care.

Liver function effects of SGLT2 inhibitor and GLP-1 receptor agonist combination treatment in patients with type 2 diabetes (post hoc analysis of RECAP study)

AIM

The favor effect on liver disease by odium-glucose cotransporter inhibitor (SGLT2i) and GLP-1 receptor agonist (GLP1Ra) was reported; however, the effect of the combination treatment of these drugs was not well known.

METHODS

We retrospectively analyzed data for 643 patients with type 2 diabetes receiving SGLT2i + GLP1Ra combination treatment for at least 1 year (331 and 312 patients in the GLP1Ra- and SGLT2i-preceding groups, respectively). Propensity score (PS) matching was used to compare the effects of the preceding drugs on liver function.

RESULTS

The mean AST and ALT values at baseline, at the initiation of combination treatment, and at final observation were 29.8 ± 20.0 and 37.7 ± 29.5, 28.7 ± 17.3 and 35.3 ± 6.0, 26.0 ± 14.6 and 30.1 ± 21.6 IU/L, respectively, indicative of significant improvements in liver function (P < 0.001). Conversely, significant progress in the fibrosis-4 (FIB-4) index category was observed even after the combination treatment (P = 0.03). Subgroup analysis revealed that a significant decrease in ALT was observed only in patients with a baseline ALT ≥30 IU/L after the combination treatment (P = 0.005). Improvement of the FIB-4 index category was observed in patients in the baseline FIB-4 index ≥2.6 group and in the 1.3 ≤FIB-4 index <2.6 group (46% and 19%, respectively). The matched model showed no significant differences in liver function after combination treatment between the SGLT2i- and GLP1Ra-preceding groups.

CONCLUSIONS

SGLT2i + GLP1Ra combination treatment significantly improved liver dysfunction and prevented the progression of FIB-4 index category among patients with an FIB-4 index ≥1.3.

Influence of glucagon-like peptide-1 receptor agonists on renal parameters: a meta-analysis of randomized controlled trials

AIMS

To verify the influence of glucagon-like peptide-1 receptor agonists (GLP-1 RA) on renal function parameters in type 2 diabetes based on well-known randomized controlled trials (RCTs).

METHODS

PubMed, Cochrane, Web of Science, Embase, and grey literature were searched for RCTs published until December 24, 2024. The quality of the RCTs was assessed using the Cochrane risk-of-bias tool. Weighted mean differences (WMD) and 95% confidence intervals (CIs) were calculated for continuous variables using meta-analysis. The primary outcomes were composite renal function parameters, including serum creatinine (Cr) levels, estimated glomerular filtration rate (eGFR), urinary albumin excretion (UAE), and urinary albumin-to-creatinine ratio (UACR).

RESULTS

Pooled data from 24 studies revealed that GLP-1 RA positively influenced renal outcomes in the type 2 diabetes group to some extent compared with that in the control group. GLP- 1 RA decreased serum creatinine levels (WMD=-0.10, 95%CI -0.19 to -0.01, I2 = 33%, P < 0.05), eGFR(WMD = 0.54, 95% CI 0.19 to 0.90, I2 = 27%, P < 0.05), UAE (WMD=-11.92, 95% CI - 23.50 to - 0.33, I2 = 0%, P < 0.05) and UACR (WMD: -1.01 mg/g, 95% CI:-1.68, -0.34, I2 = 15%, P < 0.05) in the type 2 diabetes group.

CONCLUSION

GLP-1 RA treatment significantly elevated eGFR, decreased the UACR, and positively influenced renal function outcomes in the type 2 diabetes group.

CVOT summit report 2024: new cardiovascular, kidney, and metabolic outcomes

The 10th Cardiovascular Outcome Trial (CVOT) Summit: Congress on Cardiovascular, Kidney, and Metabolic Outcomes was held virtually on December 5-6, 2024. This year, discussions about cardiovascular (CV) and kidney outcome trials centered on the recent findings from studies involving empagliflozin (EMPACT-MI), semaglutide (STEP-HFpEF-DM and FLOW), tirzepatide (SURMOUNT-OSA and SUMMIT), and finerenone (FINEARTS-HF). These studies represent significant advances in reducing the risk of major adverse cardiovascular events (MACE) and improving metabolic outcomes in heart failure with preserved ejection fraction (HFpEF), chronic kidney disease (CKD), and obstructive sleep apnea (OSA). The congress also comprised sessions on novel and established therapies for managing HFpEF, CKD, and obesity; guidelines for managing CKD and metabolic dysfunction-associated steatotic liver disease (MASLD); organ crosstalk and the development of cardio-kidney-metabolic (CKM) syndrome; precision medicine and person-centered management of diabetes, obesity, cardiovascular disease (CVD) and CKD; early detection of type 1 diabetes (T1D) and strategies to delay its onset; continuous glucose monitoring (CGM) and automated insulin delivery (AID); cardiovascular autonomic neuropathy (CAN) and the diabetic heart; and the role of primary care in the early detection, prevention and management of CKM diseases. The contribution of environmental plastic pollution to CVD risk, the increasing understanding of the efficacy and safety of incretin therapies in the treatment of CKM diseases, and the latest updates on nutrition strategies for CKM management under incretin-based therapies were also topics of interest for a vast audience of endocrinologists, diabetologists, cardiologists, nephrologists and primary care physicians, who actively engaged in online discussions. The 11th CVOT Summit will be held virtually on November 20-21, 2025 ( http://www.cvot.org ).

GLP-1 receptor agonists, are we witnessing the emergence of a paradigm shift for neuro-cardio-metabolic disorders?

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have emerged as groundbreaking therapeutic agents in managing a spectrum of metabolic disorders, demonstrating remarkable efficacy across multiple organ systems and disease states. These compounds are not only well-established in the treatment of type 2 diabetes (T2D) and obesity-conditions for which they have received widespread approval-but also exhibit promising potential in addressing cardiovascular disease (CVD) and Metabolic dysfunction-associated steatotic liver disease (MASLD). Recent investigations have begun to illuminate the utility of GLP-1RAs in the management of type 1 diabetes (T1D), as well as neurodegenerative disorders such as Alzheimer's and Parkinson's disease and various behavioral disorders. A plethora of clinical trials have consistently validated the capacity of GLP-1RAs to improve glycemic control, promote weight loss, and mitigate cardiovascular risk factors in individuals with T2D and obesity. While their application in T1D remains limited due to safety concerns-particularly regarding the risks of hypoglycemia and hyperglycemic ketoacidosis-emerging data suggest that GLP-1RAs may offer hepatoprotective benefits, potentially reducing liver fat content and decelerating the progression of MASLD. The neuroprotective attributes of GLP-1 RAs have garnered significant interest, with research indicating their potential to alleviate cognitive decline associated with neurodegenerative diseases. Furthermore, preliminary findings highlight the role of GLP-1 RAs in addressing behavioral disorders, emphasizing their extensive therapeutic promise. This comprehensive review synthesizes the current evidence supporting the diverse therapeutic applications of GLP-1RAs, positioning them as "magic drug" therapies for metabolic and neurological disorders. As ongoing research continues to explore innovative applications and combinations of GLP-1RAs, the landscape of disease management in metabolic and neurological contexts is poised for transformative advancements. This review will also critically assess safety considerations and underscore the need for personalized treatment strategies to optimize patient outcomes in these complex and often comorbid conditions.

Renoprotective mechanisms of glucagon-like peptide-1 receptor agonists

Glucagon-like peptide-1 (GLP-1) is an incretin hormone, secreted from gut endocrine cells, which acts to potentiate nutrient-induced insulin secretion. Activation of its receptor, GLP-1R, decreases glucagon secretion and gastric emptying, thereby decreasing blood glucose and body weight. It is largely through these mechanisms that Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have transformed the treatment of type 2 diabetes. More recently, preclinical and clinical studies have reported that these agents have potent extra-pancreatic effects, exhibiting cardioprotective and renoprotective actions. The recent FLOW trial was the first multicentre clinical trial investigating the effect of GLP-1RAs on a primary renal outcome and reported robust evidence that GLP-1RAs are renoprotective. Studies in rodent models of renal injury have shown that gain and loss of GLP-1R signalling improves or deteriorates kidney function. However, the precise mechanisms responsible for renal benefits of GLP-1RAs are not yet fully understood. While prolonged activation of GLP-1 receptors (GLP-1R) has been shown to reverse diabetes-related disruptions in gene expression across various renal cell populations, GLP-1R expression in both rodent and human kidneys is thought to be primarily confined to certain vascular smooth muscle cells. This review discusses recent advances in our understanding of the effects of GLP-1 medicines on the kidney with a focus on indirect and direct mechanisms of action.

Cardioprotective Glucose-Lowering Agents and Dementia Risk: A Systematic Review and Meta-Analysis

Importance

Although diabetes is a risk factor for dementia, the effect of glucose-lowering therapy for prevention of incident dementia is uncertain.

Objective

To determine whether cardioprotective glucose-lowering therapy (sodium-glucose cotransporter-2 inhibitors [SGLT2is], glucagon-like peptide-1 receptor agonists [GLP-1RAs], metformin, and pioglitazone), compared with controls, was associated with a reduction in risk of dementia or cognitive impairment, and among primary dementia subtypes.

Data Sources

The PubMed and Embase databases were searched for studies published from inception of the database to July 11, 2024.

Study Selection

Randomized clinical trials comparing cardioprotective glucose-lowering therapy with controls that reported dementia or change in cognitive scores. Cardioprotective glucose-lowering therapies were defined as drug classes recommended by guidelines for reduction of cardiovascular events, based on evidence from phase III randomized clinical trials. Inclusion criteria were assessed independently and inconsistencies were resolved by consensus.

Data Extraction and Synthesis

Data were screened and extracted independently by 2 authors adhering to the PRISMA guidelines in August 2024. Random-effects meta-analysis models were used to estimate a pooled treatment effect.

Main Outcomes and Measures

The primary outcome measure was dementia or cognitive impairment. The secondary outcomes were primary dementia subtypes, including vascular and Alzheimer dementia, and change in cognitive scores.

Results

Twenty-six randomized clinical trials were eligible for inclusion (N = 164 531 participants), of which 23 trials (n = 160 191 participants) reported the incidence of dementia or cognitive impairment, including 12 trials evaluating SGLT2is, 10 trials evaluating GLP-1RAs, and 1 trial evaluating pioglitazone (no trials of metformin were identified). The mean (SD) age of trial participants was 64.4 (3.5) years and 57 470 (34.9%) were women. Overall, cardioprotective glucose-lowering therapy was not significantly associated with a reduction in cognitive impairment or dementia (odds ratio [OR], 0.83 [95% CI, 0.60-1.14]). Among drug classes, GLP-1RAs were associated with a statistically significant reduction in dementia (OR, 0.55 [95% CI, 0.35-0.86]), but not SGLT2is (OR, 1.20 [95% CI, 0.67-2.17]; P value for heterogeneity = .04).

Conclusions and Relevance

While cardioprotective glucose-lowering therapies were not associated with an overall reduction in all-cause dementia, this meta-analysis of randomized clinical trials found that glucose lowering with GLP-1RAs was associated with a statistically significant reduction in all-cause dementia.

Kidney and Cardiovascular Outcomes Among Patients With CKD Receiving GLP-1 Receptor Agonists: A Systematic Review and Meta-Analysis of Randomized Trials

RATIONALE & OBJECTIVE

Glucagon-like peptide 1 (GLP-1) receptor agonists improve cardiac and kidney outcomes in patients with diabetes; however, their efficacy in individuals with reduced estimated glomerular filtration rate (eGFR) is uncertain. This study evaluated the effects of GLP-1 receptor agonists on kidney and cardiovascular (CV) outcomes in patients with chronic kidney disease (CKD).

STUDY DESIGN

Systematic review and meta-analysis of randomized controlled trials (RCTs) reported through May 25, 2024.

SETTING & STUDY POPULATIONS

Adult participants in RCTs with baseline eGFR<60mL/min/1.73m2.

SELECTION CRITERIA FOR STUDIES

RCTs including adults (≥18 years old) with varying degrees of kidney function, including individuals with CKD characterized by a baseline eGFR of<60mL/min/1.73m2, that compared GLP-1 receptor agonists with control treatments with respect to a composite kidney outcome, all-cause mortality, or a composite CV disease outcome. From among 212 screened studies, 12 trials involving that included participants with baseline eGFR<60mL/min/1.73m2 were included.

DATA EXTRACTION

Two independent investigators extracted the data.

ANALYTICAL APPROACH

Pooled odds ratios (ORs) for composite kidney outcome, all-cause mortality, and composite CV outcome were estimated using random-effects models. Evidence certainty was assessed using the GRADE system.

RESULTS

The analyses included 17,996 RCT participants with baseline eGFR<60mL/min/1.73m2. GLP-1 receptor agonists were significantly associated with a reduced risk of the composite kidney outcome (OR, 0.85 [95% CI, 0.77-0.94]; P=0.001) with low heterogeneity (I2<0.01%). GLP-1 receptor agonists were also associated with a reduced the risk of a>30% eGFR decline (OR, 0.78; P=0.004), a>40% decline (OR, 0.76; P=0.01), and a>50% decline (OR, 0.72; P<0.001). Risk of all-cause mortality was also lower in the GLP-1 receptor agonist group (OR, 0.77 [95% CI, 0.60-0.98], P=0.03), though there was high heterogeneity (I2=71.6%). Composite CV outcomes were also lower with the use of a GLP-1 receptor agonist (OR, 0.86 [95% CI, 0.74-0.99], P=0.03; I2=40.3%). Sensitivity analyses restricted to human GLP-1 backbone agents showed enhanced benefits.

LIMITATIONS

Inconsistent kidney outcome definitions, focus on diabetic populations in most studies, and potential publication bias.

CONCLUSIONS

GLP-1 receptor agonists improved kidney and CV outcomes, and survival in patients with CKD enrolled in an array of clinical trials.

PLAIN-LANGUAGE SUMMARY

Glucagon-like peptide 1 (GLP-1) receptor agonists reduce body weight and improve glycemic control. They also have been shown to protect the heart and kidney in people with diabetes. However, the extrapolation of these findings to those with chronic kidney disease (CKD) is uncertain. This study meta-analyzed data from clinical trials focusing on patients with CKD and noted that GLP-1 receptor agonists may slow kidney disease progression and lower the risk of heart disease, stroke, and death. These findings suggest that GLP-1 receptor agonists offer multiple kidney and cardiovascular benefits to people with CKD.

Effect of glucagon-like peptide-1 receptor agonists on the risk of major adverse limb events in patients with type 2 diabetes mellitus: A systematic review and meta-analysis of randomized clinical trials

OBJECTIVE

To evaluate the effect of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on the risk of major adverse limb events (MALE).

METHODS

We conducted a systematic review and meta-analysis of randomized clinical trials assessing the effects of GLP-1RAs therapy on peripheral arterial disease (PAD)-related outcomes in patients with type 2 diabetes mellitus (T2DM). This meta-analysis was performed according to PRISMA guidelines. The random-effects model was performed.

RESULTS

A total of 6 randomized clinical trials were considered eligible for this systematic review. On the other hand, 4 clinical trials were included for the meta-analysis. A total of 15,427 subjects were allocated to the GLP-1RAs group, and 15,476 to the placebo group. Overall, this meta-analysis showed that the use of GLP-1RAs is associated with a lower risk of PAD-related events (OR, 0.78; 95%CI, 0.62-0.98, I2=39%) vs the placebo group. The analytical evaluation did not suggest publication bias, and the sensitivity analysis demonstrated that the result was robust.

CONCLUSION

This meta-analysis demonstrated that the use of GLP-1RAs is associated with fewer PAD-related clinical events. Of note, despite the clinical significance of PAD, most analyzed studies did not specifically report on these events. Future studies should include PAD as a key endpoint.

SGLT2 Inhibitors and GLP-1 Receptor Agonists in Diabetic Kidney Disease: Evolving Evidence and Clinical Application

Diabetic kidney disease (DKD) is a leading cause of end-stage kidney disease and significantly increases cardiovascular risk and mortality. Despite conventional therapies, including renin-angiotensin-aldosterone system inhibitors, substantial residual risk remains. The emergence of sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists has reshaped DKD management. Beyond glycemic control, these agents provide distinct and complementary cardiorenal benefits through mechanisms such as hemodynamic modulation, anti-inflammatory effects, and metabolic adaptations. Landmark trials, including CREDENCE, DAPA-CKD, EMPA-KIDNEY, and FLOW, have demonstrated their efficacy in preserving kidney function and reducing adverse outcomes. SGLT2 inhibitors appear more effective in mitigating glomerular hyperfiltration and lowering heart failure risk, whereas GLP-1 receptor agonists are particularly beneficial in reducing albuminuria and atherosclerotic cardiovascular events. Although indirect comparisons suggest that SGLT2 inhibitors may offer greater protection against kidney function decline, direct head-to-head trials are lacking. Combination therapy holds promise, however further studies are needed to define optimal treatment strategies. This review synthesizes current evidence, evaluates comparative effectiveness, and outlines future directions in DKD management, emphasizing precision medicine approaches to enhance clinical outcomes. The integration of these therapies represents a paradigm shift in diabetes care, expanding treatment options for people with diabetes mellitus at risk of kidney failure.

Real-World Comparisons Between Glucagon-Like Peptide-1 Receptor Agonists and Other Glucose-Lowering Agents in Type 2 Diabetes: Retrospective Analyses of Cardiovascular and Economic Outcomes in England

INTRODUCTION

Clinical trials have demonstrated that glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduce the risk of major adverse cardiovascular events (MACE) in adults with type 2 diabetes (T2D) who have established cardiovascular disease (CVD) or a high risk of CVD. Nevertheless, GLP-1RAs remain underutilized. This real-world, retrospective study compared cardiovascular and economic outcomes between individuals treated with GLP-1RAs and other glucose-lowering agents in England.

METHODS

Clinical Practice Research Datalink-registered people indexed on GLP-1RAs, dipeptidyl peptidase-4 (DPP4) inhibitors, or basal insulin between January 1, 2014 and December 31, 2018 for their fourth line of T2D treatment were stratified into six cohorts based on their: (1) cardiovascular risk (high or very high risk) and (2) indexed therapy. Cox proportional hazards regression was used to compare the risk of MACE and all-cause death between GLP-1RA and other treatment cohorts. Generalized linear regression was used to quantify differences in healthcare resource use (HCRU) and costs between groups.

RESULTS

Of 63,237 subjects, 10,607 were at high cardiovascular risk (GLP-1RA: 2709; DPP4 inhibitor: 2673; basal insulin: 5225) and 52,630 at very high cardiovascular risk (GLP-1RA: 14,692; DPP4 inhibitor: 18,461; basal insulin: 19,477). The crude incidence of all outcomes was lower in the GLP-1RA versus other treatment cohorts, regardless of cardiovascular risk. Among very-high-risk individuals treated with GLP-1RA, the adjusted risk of MACE was 33% (24-40%) and 23% (13-23%) lower versus DPP4 inhibitor and basal insulin cohorts, respectively. The adjusted total cardiovascular-related cost among very-high-risk individuals was £208.14 (£155.81-£260.47) and £151.74 (£110.69-£192.79) lower in the GLP-1RA versus DPP4 inhibitor or basal insulin cohorts, respectively.

CONCLUSIONS

In a real-world setting, GLP-1RAs may be associated with a lower risk of MACE and reduced HCRU and costs than DPP4 inhibitors or basal insulin in individuals with T2D, particularly among those at very high cardiovascular risk.

Glucagon-like peptide-1 receptor agonists to improve cardiorenal outcomes: data from FLOW and beyond

PURPOSE OF REVIEW

Glucagon-like peptide-1 receptor agonists (GLP1RA), initially approved for glycemic control in type 2 diabetes mellitus (T2DM), have emerged as agents for weight loss, cardiovascular and kidney protection. This review summarizes the evidence supporting the benefits of these therapies on cardiorenal outcomes.

RECENT FINDINGS

Clinical trials have consistently demonstrated reductions in major adverse cardiovascular events with GLP1RA treatments. Recently, the FLOW trial revealed that semaglutide reduced the composite outcome of kidney failure, at least 50% decline in estimated glomerular filtration rate, kidney or cardiovascular mortality by 24% in patients with T2DM, thereby establishing GLP1RA as a pillar of therapy in this population. New evidence suggests favorable effects on kidney endpoints in nondiabetic individuals with overweight or obesity. Dedicated trials have also provided evidence for reduction in the risk for heart failure hospitalization and improvement in symptoms in individuals with heart failure with preserved ejection fraction. Subgroup analyses have suggested that GLP1RAs confer additive cardiorenal benefits irrespective of background medication use.

SUMMARY

There is increasing evidence that GLP1RA reduces the risk for cardiovascular events, chronic kidney disease progression, and heart failure hospitalizations. Further data on the effect of dual and triple GLP1-based therapies on cardiorenal outcomes is required.

Evolving Role of Double and Triple Therapy With GLP-1 Receptor Agonists in Obesity and Cardiovascular Disease

Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have emerged as a transformative class of therapies, expanding their clinical utility far beyond glycemic control. Initially developed for the treatment of diabetes, these agents are now recognised as potent therapies for managing overweight and obesity, atherosclerosis, and heart failure. This review explores the evolution of GLP-1RA-based therapies, with a focus on novel advances such as dual GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists ("double G") and triple receptor agonists incorporating glucagon modulation ("triple G"). We also provide an overview of completed and ongoing clinical trials investigating the role of GLP-1RAs in atherosclerosis and heart failure. These developments underscore the expanding therapeutic landscape of GLP-1RAs and their growing significance in cardiometabolic medicine.

Diabetes and calcific aortic valve disease: implications of glucose-lowering medication as potential therapy

Calcific aortic valve disease (CAVD) is a progressive disease, of which the 2-year mortality is >50% for symptomatic disease. However, there are currently no pharmacotherapies to prevent the progression of CAVD unless transcatheter or surgical aortic valve replacement is performed. The prevalence of diabetes among CAVD has increased rapidly in recent decades, especially among those undergoing aortic valve replacement. Diabetes and its comorbidities, such as hypertension, hyperlipidemia, chronic kidney disease and ageing, participated jointly in the initiation and progression of CAVD, which increased the management complexity in patients with CAVD. Except from hyperglycemia, the molecular links between diabetes and CAVD included inflammation, oxidative stress and endothelial dysfunction. Traditional cardiovascular drugs like lipid-lowering agents and renin-angiotensin system blocking drugs have proven to be unsuccessful in retarding the progression of CAVD in clinical trials. In recent years, almost all kinds of glucose-lowering medications have been specifically assessed for decelerating the development of CAVD. Based on the efficacy for atherosclerotic cardiovascular disease and CAVD, this review summarized current knowledge about glucose-lowering medications as promising treatment options with the potential to retard CAVD.

Glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter-2 inhibitors combination therapy for adults with type 2 diabetes mellitus: a network meta-analysis

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: Primary objective To evaluate the relative benefits and harms of therapy with glucagon-like peptide-1 receptor agonists (GLP-1RA), sodium-glucose co-transporter-2 inhibitors (SGLT2i), and their combination in adults with type 2 diabetes mellitus. Secondary objectives To determine the relative rankings of GLP-1RA, SGLT2i, and their combination, according to their comparative efficacy for the critical outcomes identified in this review through a network meta-analysis.

Emerging Biomarkers and Innovative Therapeutic Strategies in Diabetic Kidney Disease: A Pathway to Precision Medicine

Diabetes mellitus (DM) has emerged as the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally in recent years. Diabetic nephropathy (DN), or diabetic kidney disease (DKD) that occurs as a direct consequence of DM, has complex pathophysiological mechanisms, such as various inflammatory processes and genetic and epigenetic factors, often accentuated by comorbid illnesses like hypertension and dyslipidemia. Therefore, management of DKD involves targeting these etio-pathological processes. Various medications with remarkable disease modifying properties have been introduced for treatment of DN in recent years. We update the current and future diagnostic and therapeutic landscapes against DKD in this article.

Cardiovascular disease in chronic kidney disease

Individuals with chronic kidney disease (CKD) exhibit an increased risk for the development of cardiovascular disease (CVD) with its manifestations coronary artery disease, stroke, heart failure, arrhythmias, and sudden cardiac death. The presence of both, CVD and CKD has a major impact on the prognosis of patients. This association likely reflects the involvement of several pathophysiological mechanisms, including shared risk factors (e.g. diabetes and hypertension), as well as other factors such as inflammation, anaemia, volume overload, and the presence of uraemic toxins. Identifying and characterizing CKD is crucial for appropriate CVD risk prediction. Mitigating CVD risk in patients with CKD mandates a multidisciplinary approach involving cardiologists, nephrologists, and other health care professionals. The present State-of-the-Art Review addresses the current understanding on the pathophysiological link between CVD and CKD, clinical implications and challenges in the treatment of these patients.

The pharmacodynamics-based prophylactic benefits of GLP-1 receptor agonists and SGLT2 inhibitors on neurodegenerative diseases: evidence from a network meta-analysis

BACKGROUND

Glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors represent a new generation of antihyperglycemic agents that operate through mechanisms distinct from conventional diabetes treatments. Beyond their metabolic effects, these medications have demonstrated neuroprotective properties in preclinical studies. While clinical trials have explored their therapeutic potential in established neurodegenerative conditions, their role in disease prevention remains unclear. We conducted a network meta-analysis (NMA) to comprehensively evaluate the prophylactic benefits of these agents across multiple neurodegenerative diseases and identify the most promising preventive strategies.

METHODS

We systematically searched PubMed, Embase, ClinicalKey, Cochrane CENTRAL, ProQuest, ScienceDirect, Web of Science, and ClinicalTrials.gov through October 24th, 2024, for randomized controlled trials (RCTs) of GLP-1 receptor agonists or SGLT2 inhibitors. Our primary outcome was the incidence of seven major neurodegenerative diseases: Parkinson's disease, Alzheimer's disease, Lewy body dementia, multiple sclerosis, amyotrophic lateral sclerosis, frontotemporal dementia, and Huntington's disease. Secondary outcomes included safety profiles assessed through dropout rates. We performed a frequentist-based NMA and evaluated risk of bias with Risk of Bias tool. The main result of the primary outcome in the current study would be re-affirmed via sensitivity test with Bayesian-based NMA.

RESULTS

Our analysis encompassed 22 RCTs involving 138,282 participants (mean age 64.8 years, 36.4% female). Among all investigated medications, only dapagliflozin demonstrated significant prophylactic benefits, specifically in preventing Parkinson's disease (odds ratio = 0.28, 95% confidence intervals = 0.09 to 0.93) compared to controls. Neither GLP-1 receptor agonists nor other SGLT2 inhibitors showed significant preventive effects for any of the investigated neurodegenerative conditions. Drop-out rates were comparable across all treatments.

CONCLUSIONS

This comprehensive NMA reveals a novel and specific prophylactic effect of dapagliflozin against Parkinson's disease, representing a potential breakthrough in preventive neurology. The specificity of dapagliflozin's protective effect to Parkinson's disease might rely on its highly selective inhibition to SGLT2. These findings provide important direction for future research and could inform preventive strategies for populations at risk of Parkinson's disease.

Effect of oral semaglutide on remnant-like lipoprotein cholesterol in patients with ischemic heart disease receiving statin therapy

Objectives

High remnant-like lipoprotein (RLP) cholesterolemia has been reported as a risk factor for cardiovascular events in stable angina patients receiving statin therapy. However, there are no established treatments for lowering RLP cholesterol in patients on statins. Glucagon-Like Peptide-1 (GLP-1) receptor agonists are known to reduce cardiovascular events, but the underlying mechanism is not fully understood. We hypothesized that the lipid profile-improving effects of GLP-1 receptor agonists may also contribute to lowering RLP cholesterol.The purpose of this study was to investigate whether oral semaglutide, a GLP-1 receptor agonist, exerts a cholesterol-lowering effect on RLP cholesterol.

Methods

This study was designed as a single-center, single-group, before-and-after comparison trial. The study population consisted of patients with ischemic heart disease who were receiving statin therapy, had initiated oral semaglutide for diabetes, and had an RLP cholesterol level of 3.9 mg/dL or higher before starting semaglutide (N = 41). RLP cholesterol levels were measured in all patients 3 months after initiating semaglutide therapy. RLP cholesterol levels before and after semaglutide treatment were compared.

Results

After initiating semaglutide, RLP cholesterol levels were significantly lower compared to baseline levels (before 8.52 ± 3.96 mg/dL After 5.46 ± 2.88 mg/dL, P < 0.001). In 21 patients who switched from DPP-4 inhibitors to semaglutide, RLP cholesterol levels also significantly decreased (7.33 ± 1.03 mg/dL → 6.75 ± 0.95 mg/dL, P < 0.001). Additionally, among 30 patients who were already on SGLT-2 inhibitors, RLP cholesterol levels significantly decreased after starting semaglutide (8.01 ± 3.37 mg/dL → 5.42 ± 2.37 mg/dL, P < 0.001). No correlation was observed between the reduction in RLP cholesterol and weight loss.

Conclusions

Oral semaglutide significantly reduced RLP cholesterol levels in patients with ischemic heart disease who were receiving statin therapy.

Clinical Practice Guideline for detection and management of diabetic kidney disease: A consensus report by the Spanish Society of Nephrology

To address all the changes in the management of people with diabetes (DM) and chronic kidney disease (CKD), under the auspices of the Spanish Society of Nephrology (SEN), the Spanish Diabetic Nephropathy Study Group (GEENDIAB) decided to publish an updated Clinical Practice Guideline for detection and management of diabetic kidney disease (DKD). It is aimed at a wide audience of clinicians treating diabetes and CKD. The terminology of kidney disease in diabetic patients has evolved toward a more inclusive nomenclature that avoids underdiagnosis of this entity. Thus, the terms "diabetes and kidney disease" and "diabetic kidney disease" are those proposed in the latest KDIGO 2022 guidelines to designate the whole spectrum of patients who can benefit from a comprehensive therapeutic approach only differentiated according to eGFR range and albuminuria. Recommendations have been divided into five main areas of interest: Chapter 1: Screening and diagnosis of diabetic kidney disease, Chapter 2: Metabolic control in people with diabetes and CKD, Chapter 3: Blood pressure control in people with diabetic kidney disease, Chapter 4: Treatment targeting progression of CKD in people with diabetic kidney disease, and Chapter 5: Antiplatelet or anticoagulant therapy in people with diabetes and CKD. World Health Organization (WHO) recommendations for guideline development were followed to report this guideline. Systematic reviews were carried out, with outcome ratings and summaries of findings, and we reported the strength of recommendations following the "Grading of Recommendations Assessment, Development and Evaluation" GRADE evidence profiles.

2025 ACC/AHA/ACEP/NAEMSP/SCAI Guideline for the Management of Patients With Acute Coronary Syndromes: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines

AIM

The "2025 ACC/AHA/ACEP/NAEMSP/SCAI Guideline for the Management of Patients With Acute Coronary Syndromes" incorporates new evidence since the "2013 ACCF/AHA Guideline for the Management of ST-Elevation Myocardial Infarction" and the corresponding "2014 AHA/ACC Guideline for the Management of Patients With Non-ST-Elevation Acute Coronary Syndromes" and the "2015 ACC/AHA/SCAI Focused Update on Primary Percutaneous Coronary Intervention for Patients With ST-Elevation Myocardial Infarction." The "2025 ACC/AHA/ACEP/NAEMSP/SCAI Guideline for the Management of Patients With Acute Coronary Syndromes" and the "2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization" retire and replace, respectively, the "2016 ACC/AHA Guideline Focused Update on Duration of Dual Antiplatelet Therapy in Patients With Coronary Artery Disease."

METHODS

A comprehensive literature search was conducted from July 2023 to April 2024. Clinical studies, systematic reviews and meta-analyses, and other evidence conducted on human participants were identified that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline.

STRUCTURE

Many recommendations from previously published guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Cardioprotective benefits of metabolic surgery and GLP-1 receptor agonist-based therapies

Individuals with excessive adipose tissue and type 2 diabetes mellitus (T2DM) face a heightened risk of cardiovascular morbidity and mortality. Metabolic surgery is an effective therapy for people with severe obesity to achieve significant weight loss. Additionally, metabolic surgery improves blood glucose levels and can lead to T2DM remission, reducing major adverse cardiovascular outcomes (MACE). Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RAs) are a class of medication that effectively reduce body weight and MACE in patients with T2DM. This review explores the potential mechanisms underlying the cardioprotective benefits of metabolic surgery and GLP-1RA-based therapies and discusses recent evidence and emerging therapies in this dynamic area of research.

Efficacy of glucagon-like peptide-1 receptor agonists for prevention of stroke among patients with and without diabetes: A meta-analysis with the SELECT and FLOW trails

Background

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown a reduction in major adverse cardiovascular events (MACE) among patients with type 2 diabetes mellitus (T2DM). However, its efficacy on cerebrovascular events is yet to be well established among diabetic and non diabetic patients.

Objective

We sought to evaluate the efficacy of GLP-1 RAs on stroke risk among its different types in patients with and without Diabetes.

Methods

We performed a systematic literature search on PubMed, EMBASE, and ClinicalTrials.gov for relevant randomized controlled trials (RCTs) from inspection until 15th July 2024, without any language restrictions. Odds ratios (OR) and 95 % confidence intervals (CI) were pooled using a random-effect model, and a p-value of < 0.05 was considered statistically significant.

Results

A total of 11 RCTs with 85,373 patients were included (43,339 in GLP-1 RA and 42,034 in the placebo group) in the analysis. The mean age of the patients in GLP-1 RAs and the placebo groups was 63.5 and 63.1 years, respectively. Pooled analysis of primary and secondary endpoints showed that GLP-1 RAs significantly reduced the risk of incidence of stroke by 15 % (OR, 0.85(95 %CI: 0.77-0.93), P < 0.001) and nonfatal stroke by 13 % (OR, 0.87(95 %CI: 0.79-0.95), P < 0.001) compared with placebo. However, the risk of fatal stroke (OR, 0.94(95 %CI: 0.75-1.17), P = 0.56) was comparable between both groups of patients. Similarly, the risk of serious adverse events such as cerebrovascular accident (OR, 0.75(95 %CI: 0.57-1.00), P = 0.05), hemorrhagic stroke (OR, 0.82(95 %CI: 0.42-1.60), P = 0.57, and ischemic stroke (OR, 0.85(95 %CI: 0.64-1.13), P = 0.26) was comparable between GLP-1RAs and placebo.

Conclusion

Treatment with GLP-1 receptor agonists has beneficial effects in reducing the risk of stroke, and nonfatal stroke in patients with and without diabetes. However, no such effect was observed for fatal stroke.

Association Between the Magnitude of Glycemic Control and Body Weight Loss With GLP-1 Receptor Agonists and Risk of Atherosclerotic Cardiovascular Disease: A Systematic Review and Meta-analyses of Randomized Diabetes Cardiovascular Outcomes Trials

PURPOSE

Reduction of major atherosclerotic cardiovascular events (MACE) has not been consistent among different glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in patients with type 2 diabetes mellitus (T2DM). The aim of this study was to assess the association between the magnitude of glycemic control, body weight loss, and reductions in systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) achieved through GLP-1 RA therapy and MACE.

METHODS

Electronic databases (MEDLINE, CENTRAL, SCOPUS) were searched through March 2023. Studies were eligible if they were cardiovascular outcome trials (CVOTs) comparing GLP-1 RAs versus placebo in T2DM patients. The outcome of interest was 3-point MACE - cardiovascular death, myocardial infarction, or stroke. Random-effects meta-regression analyses evaluated the associations between reductions of HbA1c, body weight, SBP and LDL-C and reduction of MACE.

RESULTS

Overall, 8 CVOTs were included (60079 patients, 30693 with GLP-1 RAs). Reductions of HbA1C were associated with the reduction of 3P-MACE (Log RR -0.290 [95% CI -0.515;-0.064], p = 0.012), with an estimated RR reduction of 25% for each 1% absolute reduction in HbA1C levels. Body weight loss was associated with the reduction of 3P-MACE (Log RR -0.068 [95% CI -0.135;-0.001], p = 0.047), with an estimated RR reduction of 7% for each 1 kg reduction in body weight. Reductions of SBP (Log RR -0.058 [95% CI -0.192;0.076], p = 0.396) and LDL-C (Log RR -0.602 [95% CI -4.157;2.953], p = 0.740) were not associated with the reduction of 3P-MACE.

CONCLUSIONS

In T2DM patients, more potent GLP-1 RAs in reducing HbA1c and body weight were associated with greater reductions of MACE.

Discovery of non-peptide GLP-1r natural agonists for enhancing coronary safety in type 2 diabetes patients

This study explores the computational discovery of non-peptide agonists targeting the Glucagon-Like Peptide-1 Receptor (GLP-1R) to enhance the safety of major coronary outcomes in individuals affected by Type 2 Diabetes. The objective is to identify novel compounds that can activate the GLP-1R pathway without the limitations associated with peptide agonists. Type 2 diabetes mellitus (T2DM) is associated with an increased risk of cardiovascular disease (CVD) and mortality, which is attributed to the accumulation of fat in organs, including the heart. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are frequently used to manage T2DM and could potentially offer cardiovascular benefits. Therefore, this study examines non-peptide agonists of GLP-1R to improve coronary safety in type 2 diabetes patients. After rigorous assessments, two standout candidates were identified, with natural compound 12 emerging as the most promising. This study represents a notable advancement in enhancing the management of coronary outcomes among individuals with type 2 diabetes. The computational methodology employed successfully pinpointed potential GLP-1R natural agonists, providing optimism for the development of safer and more effective therapeutic interventions. Although computational methodologies have provided crucial insights, realizing the full potential of these compounds requires extensive experimental investigations, crucial in advancing therapeutic strategies for this critical patient population.

Comparison of the efficacy and safety of GLP-1 receptor agonists on cardiovascular events and risk factors: A review and network meta-analysis

OBJECTIVE

This study aims to systematically evaluate and perform a systematic review and network meta-analysis comparing the comprehensive cardiovascular protective effects of various glucagon-like peptide-1 receptor agonists (GLP-1RAs), focusing on cardiovascular events and risk factors.

METHODS

We searched PubMed, Embase, Cochrane Library and Web of Science from inception to December 15, 2024. Included studies were published randomized controlled trials (RCTs) comparing GLP-1RAs to placebo or other GLP-1RAs. Missing data were standardized, and network meta-analysis was performed using Stata 17.0. Study heterogeneity, publication bias and evidence quality were assessed using the Cochrane Risk of Bias tool and Confidence in Network Meta-Analysis (CINeMA).

RESULTS

As of December 15, 2024, a total of 18 313 articles were retrieved. Based on the inclusion and exclusion criteria, 156 high-quality studies were included, incorporating 144 782 patients and 14 different GLP-1RAs. The network meta-analysis demonstrated low heterogeneity, ensuring the reliability of the results. Comprehensive analysis revealed the following: Efpeglenatide was the most effective in reducing major adverse cardiovascular events. Oral semaglutide shows more significant advantages in reducing all-cause mortality and cardiovascular mortality. Orforglipron excelled in glycaemic control and weight reduction. SC-Semaglutide showed the greatest efficacy in lowering both systolic blood pressure and diastolic blood pressure, Liraglutide showed the greatest efficacy in lowering total cholesterol, Noiiglutide in triglycerides and Taspoglutide in low-density lipoprotein cholesterol, but no GLP-1RAs in high-density lipoprotein cholesterol. GLP-1RAs did not significantly increase the incidence of adverse events, but Orforglipron and Taspoglutide significantly increased the incidence of gastrointestinal adverse events compared with placebo.

CONCLUSION

This study compared the cardiovascular benefits of different GLP-1RAs, including reductions in cardiovascular events and improvements in multiple cardiovascular risk factors. However, due to limitations in the quantity and quality of the included studies, the conclusions should be interpreted with caution. Future large-scale, high-quality clinical trials are needed to validate these findings and further optimize comprehensive cardiovascular management strategies for patients.

Novel Antidiabetic Drugs and Risk of Venous Thromboembolism: A Literature Review

Novel antidiabetic drugs, particularly sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists, have significantly transformed the management landscape for type 2 diabetes mellitus, cardiovascular diseases, and chronic kidney diseases, owing to their well-established cardiorenal protective effects. Given the shared risk factors and comorbidities, it is relevant to consider the potential risk of venous thromboembolism (VTE) in individuals prescribed these novel antidiabetic medications. This literature review aims to summarize currently available evidence on VTE risk associated with novel antidiabetic drugs, including GLP-1 receptor agonists, dipeptidyl-peptidase IV (DPP-4) inhibitors, and SGLT2 inhibitors. Following a comprehensive search on PubMed using relevant keywords and backward reference searching, we identified 25 publications that directly reported on associations between these medications and VTE risk. Findings from these studies, including seven meta-analyses, reveal inconsistent results: some studies suggest that GLP-1 receptor agonists or DPP-4 inhibitors may be associated with increased risk of VTE, whereas SGLT2 inhibitors do not appear to be associated with VTE and may even be a protective factor. A notable limitation of the existing studies is the significant challenge posed by confounding in observational studies, while the randomized controlled trials (RCTs) often concluded with a limited number of VTE events, if it was studied. Furthermore, all identified studies focused on the risk of primary VTE, leaving an important knowledge gap regarding whether these novel antidiabetic drugs may influence the efficacy or safety of anticoagulants used for preventing VTE recurrence. Addressing these gaps presents an important avenue for future research.

Age and Sex Differences in Efficacy of Treatments for Type 2 Diabetes: A Network Meta-Analysis

Importance

Sodium-glucose cotransporter 2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and dipeptidyl peptidase 4 (DPP4) inhibitors improve hyperglycemia, and SGLT2 inhibitors and GLP-1 receptor agonists reduce the risk of major adverse cardiovascular events (MACEs) among individuals with type 2 diabetes. It is not clear whether efficacy varies by age or sex.

Objective

To assess whether age or sex are associated with differences in the efficacy of SGLT2 inhibitors, GLP-1 receptor agonists, and DPP4 inhibitors.

Data Sources and Study Selection

The MEDLINE and Embase databases and US and Chinese clinical trial registries were searched for articles published from inception to November 2022; in August 2024, the search was updated to capture the trial results. Two reviewers screened for randomized clinical trials of SGLT2 inhibitors, GLP-1 receptor agonists, or DPP4 inhibitors vs a placebo or active comparator in adults with type 2 diabetes.

Data Extraction and Synthesis

Individual participant data and aggregate data were used to estimate age × treatment interactions and sex × treatment interactions in multilevel network meta-regression models.

Main Outcome and Measures

Hemoglobin A1c (HbA1c) and MACEs.

Results

Of the 601 eligible trials identified (592 trials with 309 503 participants reported HbA1c; mean age, 58.9 [SD, 10.8] years; 42.3% were female and 23 trials with 168 489 participants reported MACEs; mean age, 64.0 [SD, 8.6] years; 35.3% were female), individual participant data were obtained for 103 trials (103 reported HbA1c and 6 reported MACEs). The use of SGLT2 inhibitors (vs placebo) was associated with less HbA1c lowering with increasing age for monotherapy (absolute reduction [AR], 0.24% [95% credible interval {CrI}, 0.10% to 0.38%] per 30-year increment in age), for dual therapy (AR, 0.17% [95% CrI, 0.10% to 0.24%]), and for triple therapy (AR, 0.25% [95% CrI, 0.20% to 0.30%]). The use of GLP-1 receptor agonists was associated with greater HbA1c lowering with increasing age for monotherapy (AR, -0.18% [95% CrI, -0.31% to -0.05%] per 30-year increment in age) and for dual therapy (AR, -0.24% [95% CrI, -0.40% to -0.07%]), but not for triple therapy (AR, 0.04% [95% CrI, -0.02% to 0.11%]). The use of DPP4 inhibitors was associated with slightly better HbA1c lowering in older people for dual therapy (AR, -0.09% [95% CrI, -0.15% to -0.03%] per 30-year increment in age), but not for monotherapy (AR, -0.08% [95% CrI, -0.18% to 0.01%]) or triple therapy (AR, -0.01% [95% CrI, -0.06% to 0.05%]). The relative reduction in MACEs with use of SGLT2 inhibitors was greater in older vs younger participants per 30-year increment in age (hazard ratio, 0.76 [95% CrI, 0.62 to 0.93]), and the relative reduction in MACEs with use of GLP-1 receptor agonists was less in older vs younger participants (hazard ratio, 1.47 [95% CrI, 1.07 to 2.02]). There was no consistent evidence for sex × treatment interactions with use of SGLT2 inhibitors and GLP-1 receptor agonists.

Conclusions and Relevance

The SGLT2 inhibitors and GLP-1 receptor agonists were associated with lower risk of MACEs. Analysis of age × treatment interactions suggested that SGLT2 inhibitors were more cardioprotective in older than in younger people despite smaller reductions in HbA1c; GLP-1 receptor agonists were more cardioprotective in younger people.

Comparative cardiovascular effectiveness of glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors in atherosclerotic cardiovascular disease phenotypes: a systematic review and meta-analysis

BACKGROUND

Atherosclerotic cardiovascular disease (ASCVD) encompasses various phenotypes with elevated risks of major adverse cardiovascular events (MACEs). This study aimed to assess the comparative cardiovascular effectiveness of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT2is) across diverse ASCVD phenotypes.

METHODS AND RESULTS

We conducted a systematic review and meta-analysis of randomized controlled trials evaluating GLP-1 RAs or SGLT2is against placebo or standard care in ASCVD patients. Primary outcomes included MACE, defined as cardiovascular mortality, non-fatal myocardial infarction, and non-fatal stroke. Risk ratios (RRs) with 95% confidence interval (CI) were calculated using a random-effects model.Twenty-six trials (151 789 patients) were included. Both GLP-1 RAs and SGLT2is significantly reduced MACE rates in ASCVD patients (RR 0.85; 95% CI 0.80-0.91 for both). GLP-1 RAs showed significant effectiveness in peripheral artery disease (RR 0.86; 95% CI 0.76-0.98) and post-acute cardiovascular events (RR 0.90; 95% CI 0.83-0.97). In ASCVD with heart failure, both drug classes reduced MACE (GLP-1 RAs: RR 0.73; 95% CI 0.63-0.84; SGLT2is: RR 0.86; 95% CI 0.78-0.95). SGLT2is significantly reduced MACE in ASCVD with chronic kidney disease (RR 0.84; 95% CI 0.72-0.99), particularly in severe albuminuria (RR 0.61; 95% CI 0.37-0.99).

CONCLUSION

GLP-1 RAs and SGLT2is exhibit distinct cardiovascular effectiveness profiles across ASCVD phenotypes. GLP-1 RAs show particular benefits in peripheral artery disease and post-acute cardiovascular events, while SGLT2is demonstrate unique advantages in ASCVD with comorbid chronic kidney disease. Both are effective in heart failure. These findings support tailored treatment strategies for diverse ASCVD participants based on specific comorbidities and risk factors.

GLP-1 receptor agonists-another promising therapy for Alport syndrome?

Alport syndrome (AS) is a progressive monogenic glomerular kidney disease characterised by kidney function decline, hearing loss, and ocular abnormalities, often leading to early-onset kidney failure (KF). While current therapies, such as renin-angiotensin system inhibitors (RASi), offer some benefits, many patients still experience KF at a young age, highlighting the need for additional treatment options. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as promising agents with demonstrated cardiovascular and nephroprotective effects in type 2 diabetes (T2D) and chronic kidney disease (CKD) patients. Evidence from several major clinical trials has shown that GLP-1 RAs can reduce cardiovascular events and slow CKD progression by reducing albuminuria. Their potential mechanisms of action include anti-inflammatory, anti-fibrotic, and antioxidative effects, making them particularly relevant for the treatment of AS, where inflammation and fibrosis play crucial roles in disease progression. This review explores the therapeutic potential of GLP-1 RAs in AS, summarising pre-clinical and clinical data and elucidating the pathways through which GLP-1 RAs might offer renoprotective benefits. We advocate for further research into their application in AS and recommend the inclusion of AS patients in future clinical trials to better understand their impact on disease progression and patient outcomes.

Comparative Cardiovascular and Renal Outcomes of Sodium-Glucose Cotransporter-2 Inhibitors and Glucagon-Like Peptide-1 Receptor Agonists in Type 2 Diabetes: A Systematic Review

This systematic review evaluates the cardiovascular and renal outcomes associated with sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists in patients with type 2 diabetes, focusing on findings from randomized controlled trials. A comprehensive search was conducted across PubMed, Embase, and the Cochrane Library, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Seven high-quality trials met the inclusion criteria, with a combined focus on major adverse cardiovascular events (MACE), heart failure hospitalizations, all-cause and cardiovascular mortality, and renal function decline. SGLT2 inhibitors demonstrated superior efficacy in reducing heart failure and renal outcomes, while GLP-1 receptor agonists were more effective in preventing MACE and improving glycemic control. Combination therapy showed potential additive benefits, particularly in improving myocardial and arterial function. The findings highlight the complementary roles of these drug classes, underscoring the importance of personalized therapy based on individual patient profiles. Further research, including long-term head-to-head trials, is warranted to validate these results and optimize treatment strategies.

Assessing the benefit-risk profile of newer glucose-lowering drugs: A systematic review and network meta-analysis of randomized outcome trials

AIM

To comprehensively evaluate the benefits and risks of glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl peptidase 4 inhibitors (DPP4i), and sodium-glucose cotransporter 2 inhibitors (SGLT2i).

MATERIALS AND METHODS

A systematic search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 2023 to identify randomized cardiovascular and kidney outcome trials that enrolled adults with type 2 diabetes, heart failure, or chronic kidney disease and compared DPP4i, GLP-1RAs, or SGLT2i to placebo. Twenty-one outcomes (e.g., major adverse cardiovascular events [MACE], stroke, and hospitalization for heart failure [HHF]) were assessed. Data were pooled using population-averaged odds ratios (ORs) with 95% CIs.

RESULTS

Twenty-six trials enrolling 198 177 participants were included. GLP-1RAs were most effective in lowering the risks of MACE (OR, 0.85, [95% CI, 0.79 to 0.92]) and stroke (0.84 [0.77, 0.91]), but increased the risk of thyroid cancer (1.58 [1.36, 2.50]). SGLT2i showed the greatest benefits in reducing the risk of HHF (0.68 [0.64, 0.73]) and improving composite renal outcomes (0.67 [0.58, 0.77]), but increased the risk of genital infections (3.11 [2.15, 4.50]). DPP4i were associated with a lower risk of certain psychiatric disorders, Parkinson's disease (0.54 [0.32, 0.92]), and amputation (0.70 [0.86, 0.93]), but an increased risk of neuropathy (1.10 [1.02, 1.18]) and pancreatitis (1.63 [1.40, 1.91]). The weighted origami plot suggested that GLP-1RAs were more suitable for reducing macrovascular and microvascular outcomes, while DPP4i might be better for neurodegenerative diseases and cancer concerns.

CONCLUSIONS

Given the distinct benefit-risk profiles, the selection of glucose-lowering drugs should be individualized based on patient characteristics and risk factors.

Mapping the effectiveness and risks of GLP-1 receptor agonists

Glucagon-like peptide 1 receptor agonists (GLP-1RAs) are increasingly being used to treat diabetes and obesity. However, their effectiveness and risks have not yet been systematically evaluated in a comprehensive set of possible health outcomes. Here, we used the US Department of Veterans Affairs databases to build a cohort of people with diabetes who initiated GLP-1RA (n = 215,970) and compared them to those who initiated sulfonylureas (n = 159,465), dipeptidyl peptidase 4 (DPP4) inhibitors (n = 117,989) or sodium-glucose cotransporter-2 (SGLT2) inhibitors (n = 258,614), a control group composed of an equal proportion of individuals initiating sulfonylureas, DPP4 inhibitors and SGLT2 inhibitors (n = 536,068), and a control group of 1,203,097 individuals who continued use of non-GLP-1RA antihyperglycemics (usual care). We used a discovery approach to systematically map an atlas of the associations of GLP-1RA use versus each comparator with 175 health outcomes. Compared to usual care, GLP-1RA use was associated with a reduced risk of substance use and psychotic disorders, seizures, neurocognitive disorders (including Alzheimer's disease and dementia), coagulation disorders, cardiometabolic disorders, infectious illnesses and several respiratory conditions. There was an increased risk of gastrointestinal disorders, hypotension, syncope, arthritic disorders, nephrolithiasis, interstitial nephritis and drug-induced pancreatitis associated with GLP-1RA use compared to usual care. The results provide insights into the benefits and risks of GLP-1RAs and may be useful for informing clinical care and guiding research agendas.

BACKGROUND

Cardiovascular outcome trials (CVOTs) suggest glucagon-like peptide 1 receptor agonists (GLP-1RAs) provide greater cardiovascular (CV) benefits in Asian compared with White individuals.

PURPOSE

Compare CV efficacy of GLP-1RAs between Asian and White individuals.

DATA SOURCES

Systematic review of PubMed and ClinicalTrials.gov (1 January 2015 to 1 November 2024).

STUDY SELECTION

Randomized placebo-controlled CVOTs of GLP-1RAs. Risk of bias was assessed (RoB 2).

DATA EXTRACTION

Ethnicity-specific hazard ratios (HRs) for major adverse cardiovascular events (MACE).

DATA SYNTHESIS

Random-effects meta-analyses per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines included eight trials (5,909 Asian individuals, 55,855 White individuals). GLP-1RA-associated MACE HR was 0.69 (95% CI 0.58, 0.83) in Asian people and 0.85 (95% CI 0.79, 0.91) in White people (Pinteraction = 0.045). Absolute MACE risk reduction was 2.9% (95% CI 1.5, 4.2) in Asian people versus 1.4% (0.9, 1.9) in White people.

LIMITATIONS

Lack of individual patient-level data precluded detailed subclassification of the Asian group.

CONCLUSIONS

GLP-1RAs may offer greater MACE reductions in Asian compared with White individuals.

The Close Link Between Obesity and Cardiovascular Disease: Current Insights and Remaining Challenges

Obesity is a global public health crisis, contributing to chronic disease development and poor prognosis. A large body of evidence consistently demonstrates that increased adiposity leads to many cardiovascular diseases (CVDs) and complications, such as coronary artery disease, heart failure, and arrhythmias, via direct and indirect mechanisms. Therefore, weight management is crucial to reduce and prevent cardiovascular risk. The recent emergence of glucose-like peptide-1 receptor agonists shows remarkable weight reduction and cardiovascular prevention. Despite the clear benefits, controversies and challenges on obesity-related CVD remain. This review aims to provide a comprehensive understanding of obesity-related CVD and explore current remaining tasks.

The pleiotropic effects of glucagon-like peptide-1 receptor agonists in patients with metabolic dysfunction-associated steatohepatitis: a review for gastroenterologists

INTRODUCTION

Glucagon-like peptide-1 receptor agonists (GLP-1RAs), and dual GLP-1/glucose-dependent insulinotropic peptide (GIP) or glucagon receptor agonists have emerged as promising agents to treat metabolic dysfunction-associated steatotic liver disease (MASLD)/metabolic dysfunction-associated steatohepatitis (MASH). Although the beneficial effects of GLP-1RAs on glycemic control and weight are well-established, clinicians may be unfamiliar with other potential benefits of this class.

AREAS COVERED

We examined the pleiotropic effects of GLP-1RAs and how they relate to gastroenterologists for MASLD/MASH treatment. Our narrative review of English articles included four GLP-1RAs (subcutaneous semaglutide, liraglutide, dulaglutide, and efpeglenatide), a dual GLP-1/GIP agonist (tirzepatide), a dual GLP-1/glucagon receptor agonist (survodutide), MASLD/MASH, related disorders, clinical management, treatment outcomes and landscape.

EXPERT OPINION

In Phase I - III trials, GLP-1RAs are associated with clinically relevant hepatic improvements including MASH resolution, liver fat reduction, and preventing worsening fibrosis. Effects on cardiometabolic parameters align with type 2 diabetes/obesity Phase III data, comprising substantial improvements in glycemic, weight, and cardiovascular outcomes. Promising data also suggest benefits in common comorbidities, including obstructive sleep apnea, polycystic ovary syndrome, chronic kidney disease, and heart failure with preserved ejection fraction.GLP-1RAs represent a valuable pharmacotherapeutic option for gastroenterologists managing individuals with MASLD/MASH and cardiometabolic comorbid conditions.

Safety, efficacy, and cardiovascular benefits of combination therapy with SGLT-2 inhibitors and GLP-1 receptor agonists in patients with diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

The potential benefits and risks of combination therapy with sodium-glucose co-transporter-2 inhibitors (SGLT-2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) versus monotherapy remain a subject of debate to optimize metabolic and cardiovascular outcomes in patients with type 2 diabetes mellitus. This study aims to systematically review and meta-analyze the available evidence from randomized controlled trials.

METHODS

A comprehensive search identified relevant randomized controlled trials comparing combination therapy with SGLT-2i and GLP-1RA to monotherapy or treatment as usual (TAU). The main outcome was the incidence of hospitalization for heart failure. Other outcomes included major adverse cardiovascular events (MACE) (cardiovascular mortality, all-cause mortality, stroke, and myocardial infarction), changes in metabolic parameters, and adverse events. Random-effects meta-analysis estimated risk ratios (RRs), mean difference (MD), and 95% confidence intervals (CIs). We assessed the risk of bias in included studies using the Cochrane ROB 2.0 tool.

RESULTS

The meta-analysis included 10 randomized controlled trials with 42,651 participants, of which 2,820 were on combination therapy and the rest on SGLT-2i (37.1%), GLP-1RA (20.1%) monotherapies or TAU (42.8%). Combination therapy had a lower risk of hospitalization for heart failure versus GLP-1RA monotherapy (RR = 0.37, 95% CI 0.22; 0.65), SGLT-2i monotherapy (RR = 0.37, 95% CI 0.19; 0.75), and TAU (RR = 0.43, 95% CI 0.24; 0.75), respectively. Combination therapy also had a significantly lower risk of MACE versus TAU (RR = 0.73, 95% CI 0.61; 0.88). Combination therapy showed greater weight loss and hemoglobin A1c reduction versus SGLT-2i monotherapy (MD = -2.20, 95% CI -3.09; -1.31 and MD = -0.74, 95% CI -1.21; -0.27), respectively, while no difference was noted versus GLP-1RA monotherapy. The incidence of nausea and diarrhea was higher with combination therapy versus SGLT-2i monotherapy (MD = 3.34, 95% CI 1.74; 6.43 and MD = 1.75, 95% CI 1.10; 2.77), respectively.

CONCLUSION

Combination therapy with SGLT-2i and GLP-1RA may provide superior cardiovascular, weight, and Hemoglobin A1c outcomes versus monotherapy despite higher gastrointestinal adverse events. These results may impact the management of patients with metabolic and cardiovascular diseases and highlight the need for further research on combination therapy to optimize outcomes.

Association of glucagon-like peptide-1 receptor agonists with cardiovascular and kidney outcomes in type 2 diabetic kidney transplant recipients

BACKGROUND

Cardiovascular disease is a leading cause of post-transplant mortality in kidney transplant recipients (KTRs), especially those with diabetes. Although glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated cardiovascular and kidney benefits in the general population with type 2 diabetes mellitus (T2DM), evidence regarding their effects in diabetic KTRs is limited.

METHODS

This retrospective cohort study utilized data from the Global Collaborative Network in TriNetX, spanning January 1, 2006, to June 1, 2023. Propensity score matching (PSM) with 1:1 ratio was employed to create balanced cohorts. Adult KTRs with T2DM who received GLP-1 RAs within 3 months post-transplant were compared to a matched cohort of KTRs who did not. The primary outcome was all-cause mortality, with secondary outcomes including major adverse cardiovascular events (MACEs) and major adverse kidney events (MAKEs).

RESULTS

A total of 35,488 adult KTRs with T2DM (mean [SD] age, 57.7 [12.2] years; 57.7% men) were identified and 9.8% patients used GLP-1 RAs among 3 months post-transplant. Following PSM, 3564 GLP-1 RAs users were matched with an equal number of nonusers. After a median follow-up of 2.5 years, GLP-1 RAs users had lower risks of mortality (adjusted hazard ratio (aHR), 0.39; 95% CI 0.31-0.50), MACEs (aHR 0.66; 95% CI 0.56-0.79), and MAKEs (aHR 0.66; 95% CI 0.58-0.75). Adverse effects included higher risks of nausea, vomiting and diarrhea, while risks of suicide, hypoglycemia, retinopathy, and pancreatitis were not increased.

CONCLUSIONS

In KTRs with T2DM, GLP-1 RAs use was associated with substantial reductions in all-cause mortality, MAKEs, and MACEs compared to nonuse without increasing complications. However, the underutilization of GLP-1 RAs represents a significant opportunity to improve post-transplant outcomes in this high-risk population.
