The article "Do nonglycaemic effects such as weight loss account for HbA1c lowering with efpeglenatide?: Insights from the AMPLITUDE‐O trial" published in Diabetes, Obesity & Metabolism explores the impact of the GLP‐1 RA efpeglenatide on HbA1c levels in individuals with type 2 diabetes. The study found that efpeglenatide significantly reduced HbA1c levels by 1.46% within 3 months, along with other positive effects on weight, blood pressure, cholesterol levels, and other health markers. However, the analysis revealed that less than 12% of efpeglenatide's effect on HbA1c could be explained by its impact on weight loss and other nonglycaemic factors. The study suggests that the glycaemic effect of efpeglenatide is primarily due to its incretin-related effects, with weight loss playing a modest role. [Extracted from the article]

Aims Materials and Methods Results Conclusion GLP‐1 receptor agonists (GLP‐1 RAs) are proven therapies for type 2 diabetes mellitus (T2DM) and overweight or obesity. We performed non‐clinical and first‐in‐human (FIH) evaluation of ECC5004/AZD5004, an oral small‐molecule GLP‐1 RA.ECC5004 was profiled in cell lines overexpressing human GLP‐1R, in glucose‐stimulated insulin secretion (GSIS) assays in a human β‐cell line and non‐human primates (NHPs). To evaluate safety, ECC5004 was orally administered to NHPs for 9 months and a phase I, double‐blind, placebo‐controlled FIH study was conducted. This study evaluated single doses of ECC5004 (1–300 mg) in healthy volunteers, and multiple daily doses (5, 10, 30 and 50 mg) in patients with T2DM for 28 days.ECC5004 bound to the hGLP‐1R (IC50 = 2.4 nM) augmented cAMP signalling without β‐arrestin‐2 recruitment or receptor internalization. ECC5004 potentiated GSIS in both EndoC‐βH5 cells (EC50 = 5.9 nM) and in vivo in NHPs (EC50 = 0.022 nM). Dose‐dependent body weight changes compared to control were seen in the 9‐month NHP toxicity study. In the first‐in‐human study, ECC5004 was well tolerated with no serious adverse events. Dose‐dependent reductions in glucose and body weight were observed with a dose‐proportional exposure at doses ≥25 mg.ECC5004 engaged the GLP‐1R across the therapeutic dose range tested and had a safety and tolerability profile consistent with other GLP‐1 RAs, along with a pharmacokinetic profile compatible with once‐daily oral dosing. These data support continued development of ECC5004 as a potential therapy for T2DM and overweight or obesity. Clinical trial registration: NCT05654831. [ABSTRACT FROM AUTHOR]

Background: Limited evidence exists to support any specific medication over others to prevent dementia in older patients with type 2 diabetes (T2D). We investigated whether treatment with sodium‐glucose cotransporter 2 (SGLT‐2) inhibitors is associated with a lower risk of incident dementia and all‐cause mortality, relative to dipeptidyl peptidase‐4 (DPP‐4) inhibitors and glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA). Methods: In this retrospective, active‐comparator cohort study, we used data from the TriNetX electronic health records network. Our primary cohort comprised patients with T2D aged ≥50 years, registered between January 2012 and December 2022. Patients with a history of dementia were excluded. We used Kaplan–Meier survival analysis to estimate the incidence of dementia and all‐cause mortality in our cohort after they had used glucose‐lowering drugs for at least 12 months. Propensity score matching was performed to balance the SGLT‐2 inhibitor, DPP‐4 inhibitor and GLP‐1 RA cohorts. Subgroup analyses for sex and age were also conducted. Results: Our first cohort comprised 193 948 patients treated with metformin and SGLT‐2 inhibitors and an equal number of patients treated with metformin and DPP‐4 inhibitors. In this cohort, the risk of dementia and all‐cause mortality was lower in patients treated with SGLT‐2 inhibitors than in those treated with DPP‐4 inhibitors (hazard ratio [HR]: 0.62, 95% confidence interval [CI]: 0.59–0.65, for dementia; HR: 0.54, 95% CI: 0.52–0.56, for all‐cause mortality). Our second cohort comprised 165 566 patients treated with metformin and SGLT‐2 inhibitors and an equal number of patients treated with metformin and GLP‐1 RAs. In this cohort, the risk of dementia and all‐cause mortality was lower in those treated with SGLT‐2 inhibitors than in those treated with GLP‐1 RAs (HR: 0.92, 95% CI: 0.87–0.98, for dementia; HR: 0.88, 95% CI: 0.85–0.91, for all‐cause mortality). Conclusions: The use of SGLT‐2 inhibitor was associated with a lower risk of incident dementia and all‐cause mortality in older adults with T2D compared to DPP‐4 inhibitor and GLP‐1 RA.

This large community-based cohort study investigates the impact of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), specifically Liraglutide and Semaglutide, on the risk of developing psychiatric conditions such as depression, anxiety, and suicidal behaviors in patients with obesity. Utilizing post-marketing data, this research compares patients prescribed GLP-1 RAs (cases) with those not taking these medications (controls). The analysis spanned data from January 1, 2015, to December 31, 2023. To minimize selection bias, we employed 1:1 propensity score matching to account for demographic factors such as age, sex, race, and comorbidities. After matching, the study included 162,253 case and control patients. This study showed a significant association between GLP-1 RA treatment and an 98% increased risk of any psychiatric disorders. Notably, patients on GLP-1 RAs exhibited a 195% higher risk of major depression, a 108% increased risk for anxiety, and a 106% elevated risk for suicidal behavior. These findings underscore the critical need for physicians to thoroughly assess patient history before prescribing GLP-1 RAs and highlight the urgent requirement for further prospective clinical trials to fully understand the implications of GLP-1 RA use on mental health in the obese patient population.

Background: Digital weight loss services (DWLSs) that use Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated potential in contributing to a shift in global obesity rates. However, reasonable concerns have been raised about the prescribing safety of these services. Prior to this study, electronic prescribing safety had only been investigated in hospital settings and community clinics. Methods: This study retrospectively analyzed prescribing errors committed over a 6-month period in 2023 at Australia's largest GLP-1 RA-supported DWLS. Results: The analysis found that 1654 (4.4%) of the 37323 audited GLP-1 RA prescriptions contained an error. Most errors pertained to insufficient safety counselling (49.15%) and inadequate investigations of potential contraindications (30.29%). Although a large portion of prescribing errors were detected via the automated query method (64.9%), the other three auditing methods all detected a significant number of true errors (>100). Patients from the highest body mass index category (40+ kg/m2) were overrepresented in the service's prescribing error data. Conclusions: These findings lay a vital foundation in the emerging literature on GLP-1 RA-supported DWLSs. [ABSTRACT FROM AUTHOR]

Quality glucose-like peptide-1 receptor agonist (GLP-1 RA)-supported digital weight-loss services (DWLSs) have the potential to play a significant role in shifting the alarming global obesity rate. Previous studies have demonstrated various aspects of their utility in Australian and British populations, but nothing has hitherto been investigated in real-world European settings, where GLP-1 RA weight therapy and digital healthcare are widely used. This study retrospectively analysed the 5-month (Mean = 160.14 days) weight-loss outcomes in a cohort of patients who received email-based health coaching and Semaglutide therapy via the Juniper Germany DWLS (n = 833). Mean weight loss was 9.52 (±5.46) percent, with 81.51% of the cohort losing a ‘meaningful’ (5% or more) amount of weight. Females (Mean = 9.75) tended to lose more weight than males (Mean = 8.41) and patients from the lowest two BMI categories (27.5–29.99 kg/m2 Mean = 10.1; 30–34.99 kg/m2 Mean = 9.74) lost significantly more weight than those in the highest BMI category (≥40 kg/m2 Mean = 8.11). These findings indicate that GLP-1 RA-supported DWLSs can contribute to meaningful weight loss in Germany. Future research should seek to conduct a dedicated adherence analysis of the Juniper Germany DWLS and measure the effect of subsidisation and baseline body mass index on general DWLS effectiveness.

Introduction: The efficacy and safety of oral semaglutide, the first glucagon-like peptide 1 receptor agonist available in tablet form for the treatment of type 2 diabetes, were established in the phase 3a PIONEER program. However, evidence regarding the titration of oral semaglutide in real-world clinical settings remains insufficient. This study aimed to elucidate the therapeutic advantages of escalating the dose of oral semaglutide from 7 to 14 mg through clinical data analysis. Methods: This retrospective observational study was conducted at a single center in Japan, focusing on adults with type 2 diabetes who were initiated on 14 mg oral semaglutide. The primary endpoint was the alteration in HbA1c levels 24 weeks after the initial prescription of 14 mg oral semaglutide. Secondary endpoints included changes in metabolic parameters and the incidence of adverse events. Results: Data from 66 patients who met the inclusion criteria were analyzed. The mean change in HbA1c levels from baseline to 24 weeks following dose escalation was − 0.5 ± 0.8% [from 7.4 ± 1.0% at baseline to 7.0 ± 0.9% at 24 weeks (p < 0.01)]. Moreover, a significant reduction in body weight of − 2.0 ± 4.4 kg was observed at 24 weeks [from 90.0 ± 20.5 kg at baseline to 88.2 ± 21.4 kg at 24 weeks (p < 0.01)], with 41% of patients achieving at least a 3% reduction compared to baseline. Gastrointestinal disorders emerged as the most prevalent adverse event (10.6%), particularly nausea (7.6%), although predominantly of mild or moderate severity, with no instances of serious adverse events necessitating drug discontinuation. Conclusion: Escalating the dose of oral semaglutide to 14 mg could be an effective approach for enhancing glycemic control and managing body weight in individuals with type 2 diabetes.

Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are novel antihyperglycemic agents. By acting through the central nervous system, they increase satiety and reduce food intake, thus lowering body weight. Furthermore, they increase the secretion of insulin while decreasing the production of glucagon. However, recent studies suggest a more complex metabolic impact through the interaction with various other tissues. In our present review, we aim to provide a summary of the effects of GLP-1 RA on serum lipids, adipose tissue, and muscle metabolism. It has been found that GLP-1 RA therapy is associated with decreased serum cholesterol levels. Epicardial adipose tissue thickness, hepatic lipid droplets, and visceral fat volume were reduced in obese patients with cardiovascular disease. GLP-1 RA therapy decreased the level of proinflammatory adipokines and reduced the expression of inflammatory genes. They have been found to reduce endoplasmic reticulum stress in adipocytes, leading to better adipocyte function and metabolism. Furthermore, GLP-1 RA therapy increased microvascular blood flow in muscle tissue, resulting in increased myocyte metabolism. They inhibited muscle atrophy and increased muscle mass and function. It was also observed that the levels of muscle-derived inflammatory cytokines decreased, and insulin sensitivity increased, resulting in improved metabolism. However, some clinical trials have been conducted on a very small number of patients, which limits the strength of these observations. [ABSTRACT FROM AUTHOR]

Context There has been growing recognition of the need for considering weight-loss strategies following metabolic bariatric surgery (MBS) to limit the magnitude of potential weight regain. The use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in this setting remains uncertain. Objective We conducted a systematic review and meta-analysis to evaluate the effect of GLP-1RAs on weight changes in patients who previously underwent MBS. Methods We examined the effect of GLP-1RAs on weight changes by calculating pooled estimates (random-effects model) of the absolute differences in body weight (kg) compared to baseline for observational studies and compared to a control group for randomized controlled trials (RCTs). A total of 17 studies (1164 participants) met our inclusion criteria. Pooling the data from the 14 observational studies evaluating the effect of GLP-1RAs post bariatric treatment demonstrated a reduction of 7.83 kg compared to pre treatment (before the use of GLP-1RA) (weight—7.83 kg [95% CI, −9.27 to −6.38]). With respect to tolerability, 23% (95% CI, 10%-36%) of participants reported any adverse event but only 7% discontinued treatment. Data from RCTs showed that the use of GLP-1RAs induced weight reduction of 4.36 kg (95% CI, −0.42 to −8.30) compared to placebo with a similar safety profile. Conclusion Our findings suggest that the use of liraglutide and semaglutide in patients who previously underwent MBS can promote significant weight reduction with an acceptable safety profile.

Abstract Objective and results description The study objective was to investigate the potential of quantitative measures of pulmonary inflammation by [18 F]Fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) as a surrogate marker of inflammation in COPD. Patients treated with anti-inflammatory Liraglutide were compared to placebo and correlated with inflammatory markers. 27 COPD-patients (14 receiving Liraglutide treatment and 13 receiving placebo) underwent 4D-respiratory-gated FDG-PET/CT before and after treatment. Two raters independently segmented the lungs from CT images and measured activity in whole lung, mean standard uptake values (SUVmean) corrected for lean-body-mass in the phase-matched PET images of the whole segmented lung volume, and total lesion glycolysis (TLG; SUVmean multiplied by volume). Inter-rater reliability was analyzed with Bland-Altman analysis and correlation plots. We found no differences in metabolic activity in the lungs between the two groups as a surrogate of pulmonary inflammation, and no changes in inflammation markers. The purpose of the research and brief summary of main findings. The degree of and changes in pulmonary inflammation in chronic obstructive pulmonary disease (COPD) may be difficult to ascertain. Measuring metabolic activity as a surrogate marker of inflammation by FDG-PET/CT may be useful, but data on its use in COPD including reproducibility is still limited, especially with respiration-gated technique, which should improve quantification in the lungs. We assessed several quantitative measures of metabolic activity and correlated them with inflammation markers, and we assessed reproducibility of the methods. We found no differences in metabolic activity between the two groups (before and after 40 weeks treatment with Liraglutide vs. placebo). Bland-Altman analysis showed good agreement between the two raters. Trial registration The study was conducted between February 2018 and March 2020 at the Department of Pulmonary Diseases at Hospital South West Jutland and Lillebaelt Hospital, Denmark, and registered from March 2018 at clinicaltrials.gov with trial registration number NCT03466021.

Aim: To compare the cardiovascular preventive effect associated with glucagon‐like‐peptide‐1 receptor agonists (GLP‐1 RA) versus dipeptidyl peptidase‐4 inhibitors (DPP‐4i) according to the achieved target level of glycated hemoglobin (HbA1c). Methods: We used retrospective Danish registries to include type 2 diabetes patients already in metformin treatment initiating GLP‐1 RA or DPP‐4i between 2007 and 2021. Patients were included 6 months after GLP‐1 RA or DPP‐4i initiation. The last available HbA1c measurement before inclusion was collected. The achieved HbA1c level was categorized according to a target level below or above 53 mmol/mol (7%). The primary outcome was a composite of nonfatal myocardial infarction, nonfatal stroke, and all‐cause death. We used a multivariable Cox proportional hazard model to estimate the effect of HbA1c levels on the outcome among GLP‐1 RA users compared to DPP‐4i users. Results: The study included 13 634 GLP‐1 RA users (median age 56.9, interquartile range [IQR]: 48.5–65.5; 53% males) and 39 839 DPP‐4i users (median age 63.4, IQR: 54.6–71.8; 61% males). The number of GLP‐1 RA and DPP‐4i users according to achieved HbA1c levels were as follows: HbA1c ≤ 53 mmol/mol (≤7.0%): 3026 (22%) versus 4824 (12%); HbA1c > 53 mmol/mol (>7.0%): 6577 (48%) versus 17 508 (44%); missing HbA1c: 4031 (30%) versus 17 507 (44%). During a median follow‐up of 5 years (IQR: 2.6–5.0), 954 GLP‐1 RA users experienced the primary outcome compared to 7093 DPP‐4i users. The 5‐year risk (95% confidence interval [CI]) of the outcome associated with GLP1‐RA versus DPP‐4i according to HbA1c categories was as follows: HbA1c ≤ 53 mmol/mol: 10.3% (8.2–12.3) versus 24.3% (22.7–25.8); HbA1c > 53 mmol/mol: 16.0% (14.3–17.6) versus 21.1% (20.3–21.9); missing HbA1c: 17.1% (15.7–18.5) versus 25.6% (24.9–26.3). The preventive effect associated with GLP‐1 RA versus DPP‐4i was significantly enhanced when achieving lower HbA1c levels: HbA1c ≤ 53 mmol/mol: 0.65 (0.52–0.80); HbA1c > 53 mmol/mol: 0.92 (0.83–1.03); missing HbA1c: 0.92 (0.84–1.02) (p value for interaction <.001). Conclusion: GLP‐1 RA use was associated with a lower rate of major adverse cardiovascular outcomes. The association was stronger in patients achieving the target glycemic level and weaker in patients not achieving the target glycemic level, suggestive of an interaction between achieved HbA1c level and GLP‐1 RA.

Purpose: The purpose of this study was to evaluate patient, prescriber, and dose characteristics and evaluate changes in glycated hemoglobin (HbA1c) for patients prescribed once weekly semaglutide for diabetes (OW sema T2D). Methods: This study was a retrospective claims-based study using the Optum Research Database. The sample included adult patients who had at least one claim for OW sema T2D between Jan 1, 2018, and Dec 31, 2019, were continuously enrolled in the health plan and had a diagnosis of type 2 diabetes (T2DM) during the pre-index or post-index periods. Demographic and clinical characteristics of patients using OW sema T2D were collected, as were the dose and prescriber specialty and the change between pre-index and post-index HbA1c measures was calculated. Results were stratified by the latest pre-index HbA1c measurement (HbA1c greater than or equal to 9.0%, uncontrolled vs. HbA1c less than 9%, controlled). Statistical comparisons between HbA1c groups were conducted. Results: Most patients, 76.3%, were prescribed a 0.25/0.50 mg dose of OW sema T2D. Patients had an overall decrease in HbA1c of 0.8% and patients with uncontrolled diabetes had a greater reduction in mean HbA1c compared to those with controlled diabetes (-2.1% vs. -0.3%, p < 0.001). Most patients had their index dose of OW sema T2D prescribed by endocrinologists (27.6%) primary care providers (24.6%) and internal medicine providers (21.6%). Conclusions: OW sema T2D is an effective real-world T2DM treatment. Future research should further investigate real-world use patterns of this medication. [ABSTRACT FROM AUTHOR]

Early initiation of intensive insulin therapy has been demonstrated to be effective in controlling glycemia and possibly preserving beta-cell function. Innovations in insulin formulations and delivery systems continue. However, we have seen an acceleration in the development of new classes of diabetes medications for individuals with type 2 diabetes and obesity, such as, for example, glucagon-like peptide-1 receptor agonists (GLP-1 RAs). These formulations have been shown to confer significant benefits in achieving good glycemic control with reduced hypoglycemia risk, weight loss, and cardiorenal protection. Therefore, it is reasonable to question whether there is still a role for insulin therapy in the management of type 2 diabetes. However, there are clear limitations inherent to GLP-1 RA therapy, including high rates of suboptimal adherence and treatment discontinuation due to high cost and side effects, which diminish long-term efficacy, and supply issues. In addition, newer formulations have shown improvements in convenience and tolerability, and have been shown to be even more effective when used in conjunction with basal insulin. In this narrative review, we discuss current evidence that supports GLP-1 RA use in combination with insulin therapy and the potential pitfalls of reliance on GLP-1 RAs as a substitute for insulin therapy.

Obesity is the modern world's current epidemic, with substantial health and economic impact. This study aimed to provide a narrative overview of the past, currently available, and future treatment options that offer therapeutic and preventive advantages for obesity management. Historically, rimonabant, and lorcaserin, were approved and used for managing non-syndromic obesity. Currently, orlistat, naltrexone/bupropion, glucagon-like peptide-1 receptor agonist (GLP-1 RA), and a few promising therapeutic agents are under investigation, including retatrutide, cagrilintide and orforglipron, which show promising weight reduction effects. We have developed a search string of the Medical Subject Headings (MeSH), including the terms GLP-1 RAs, obesity, and weight loss. This string was then used to perform a systematic literature search in the database including PubMed, EMBASE, MEDLINE, and Scopus up to January 31st, 2024. Managing obesity often requires medical interventions, particularly in cases of severe obesity or obesity-related comorbidities. Thus, it is important to approach obesity management holistically, considering individual needs and circumstances. In our opinion, consulting with healthcare professionals is crucial to developing a personalized plan that addresses both weight loss and overall health improvement. [ABSTRACT FROM AUTHOR]

Aim: Novel long‐acting drugs for type 2 diabetes mellitus may optimize patient compliance and glycaemic control. Exendin‐4‐IgG4‐Fc (E4F4) is a long‐acting glucagon‐like peptide‐1 receptor agonist. This first‐in‐human study investigated the safety, tolerability, pharmacokinetic, pharmacodynamic and immunogenicity profiles of a single subcutaneous injection of E4F4 in healthy subjects. Methods: This single‐centre, randomized, double‐blind, placebo‐controlled phase 1 clinical trial included 96 subjects in 10 sequential cohorts that were provided successively higher doses of E4F4 (0.45, 0.9, 1.8, 3.15, 4.5, 6.3, 8.1, 10.35, 12.6 and 14.85 mg) or placebo (ChinaDrugTrials.org.cn: ChiCTR2100049732). The primary endpoint was safety and tolerability of E4F4. Secondary endpoints were pharmacokinetic, pharmacodynamic and immunogenicity profiles of E4F4. Safety data to day 15 after the final subject in a cohort had been dosed were reviewed before commencing the next dose level. Results: E4F4 was safe and well tolerated among healthy Chinese participants in this study. There was no obvious dose‐dependent relationship between frequency, severity or causality of treatment‐emergent adverse events. Cmax and area under the curve of E4F4 were dose proportional over the 0.45‐14.85 mg dose range. Median Tmax and t1/2 ranged from 146 to 210 h and 199 to 252 h, respectively, across E4F4 doses, with no dose‐dependent trends. For the intravenous glucose tolerance test, area under the curve of glucose in plasma from time 0 to 180 min showed a dose‐response relationship in the 1.8‐10.35 mg dose range, with an increased response at the higher doses. Conclusion: E4F4 exhibited an acceptable safety profile and linear pharmacokinetics in healthy subjects. The recommended phase 2 dose is 4.5‐10.35 mg once every 2 weeks. [ABSTRACT FROM AUTHOR]

Introduction: Semaglutide, the only glucagon-like peptide-1 receptor agonist (GLP-1 RA) available in subcutaneous and oral formulation for treatment of type 2 diabetes (T2D), has demonstrated clinically significant improvements in glycaemic control and weight in clinical trials. This study aimed to gain insights into the use of both formulations and evaluate their clinical effectiveness in a secondary care clinic in Wales. Methods: This was a retrospective observational analysis of adults with T2D initiated on oral or subcutaneous semaglutide. Changes from baseline in glycated haemoglobin (HbA1c), weight and other metabolic parameters were evaluated. Results: At baseline, participants (n = 103) had a mean age of 57.3 years, mean HbA1c of 79.1 mmol/mol (9.38%), mean weight of 111.8 kg and body mass index (BMI) of 39.6 kg/m2 (no statistically significant differences between oral and subcutaneous groups). At 6-month follow-up, statistically significant improvements in HbA1c (− 19.3 mmol/mol [− 1.77%] and − 20.8 mmol/mol [− 1.90%]), body weight (− 9.0 kg and − 7.2 kg), and BMI (− 3.3 kg/m2 and − 2.5 kg/m2) were observed for oral and subcutaneous semaglutide, respectively. No statistically significant differences between the formulations were observed, and safety profiles were comparable. Conclusions: Both formulations of semaglutide provided clinically and statistically significant reductions in HbA1c and weight in real-world practice. Oral GLP-1 RA may offer a practical and effective option for the management of T2D. [ABSTRACT FROM AUTHOR]

Purpose: The prevalent new user design extends the active comparator new user design to include patients switching to a treatment of interest from a comparator. We examined the impact of adding "switchers" to incident new users on the estimated hazard ratio (HR) of hospitalized heart failure. Methods: Using MarketScan claims data (2000–2014), we estimated HRs of hospitalized heart failure between patients initiating GLP‐1 receptor agonists (GLP‐1 RA) and sulfonylureas (SU). We considered three estimands: (1) the effect of incident new use; (2) the effect of switching; and (3) the effect of incident new use or switching, combining the two population. We used time‐conditional propensity scores (TCPS) and time‐stratified standardized morbidity ratio (SMR) weighting to adjust for confounding. Results: We identified 76 179 GLP‐1 RA new users, of which 12% were direct switchers (within 30 days) from SU. Among incident new users, GLP‐1 RA was protective against heart failure (adjHRSMR = 0.74 [0.69, 0.80]). Among switchers, GLP‐1 RA was not protective (adjHRSMR = 0.99 [0.83, 1.18]). Results in the combined population were largely driven by the incident new users, with GLP‐1 RA having a protective effect (adjHRSMR = 0.77 [0.72, 0.83]). Results using TCPS were consistent with those estimated using SMR weighting. Conclusions: When analyses were conducted only among incident new users, GLP‐1 RA had a protective effect. However, among switchers from SU to GLP‐1 RA, the effect estimates substantially shifted toward the null. Combining patients with varying treatment histories can result in poor confounding control and camouflage important heterogeneity. [ABSTRACT FROM AUTHOR]

Type 2 diabetes mellitus (T2DM) is a chronic medical condition affecting millions of individuals worldwide. The burden of disease is significant, as demonstrated by high morbidity and mortality and billions of healthcare dollars spent. The pathophysiology of T2DM is complex, with eight primary deficits. In recent years, an increased focus has been placed on incretin hormones, such as glucagonlike peptide-1 (GLP-1) for its glucose-lowering benefits. Several FDA-approved short-acting and long-acting GLP-1 receptor agonists (GLP-1 RAs) are available in the United States for the treatment of T2DM. These are liraglutide, exenatide, dulaglutide, and semaglutide, all administered via subcutaneous injection. Semaglutide is also available in an oral formulation. A newer dual glucose-dependent insulinotropic peptide (GIP) and GLP-1 RA, tirzepatide, is available as a subcutaneous injectable. In addition to improving glycemic control, GLP-1 RAs have been shown to lower total body weight, BP, and cholesterol as well as to improve renal function and beta-cell proliferation. These agents should be considered in every patient with T2DM due to their substantial clinical benefits and potential to help reduce disease burden. [ABSTRACT FROM AUTHOR]

IntroductionGlucagon-like peptide 1 receptor agonists (GLP-1 RA) have been extensively used to treat obesity in recent years. These novel drugs are effective at reducing body weight and also the risk of major adverse cardiovascular events in individuals with type 2 diabetes. However, the data of its efficacy in reducing cardiovascular events in individuals without type 2 diabetes is not as robust. We aim to update and conduct a systematic review and meta-analysis to assess the same.MethodsThe study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guideline. Researchers searched PubMed, EMBASE, and Clinicaltrails.gov for English literature from inception to 2024. Randomized Controlled trails enrolling adult participants (age ≥ 18 years) who are overweight or obese (BMI > 25 Kg/m2) with a comparison of all cardiovascular events between patients taking GLP1-RA and placebo were included. The analysis was done by Revman version 5.4.ResultsA total of 17 RCTs among 34,419 participants were included in the analysis. The pooled risk ratio from 17 studies illustrated that patients with GLP-1 RA had a significantly lower risk of cardiovascular events compared to patients who had a placebo (RR = 0.75; 95% confidence interval 0.64–0.89, p-value = 0.0008). Semaglutide was found to have a statistically significant greatest risk reduction than other drug types.ConclusionsThis meta-analysis found that GLP-1 RA significantly reduced all types of cardiovascular events in overweight and obese patients without diabetes. Semaglutide was found to be superior to others in CV event reductions. But still, the results of ongoing trials are needed.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=553048, PROSPERO (CRD42024553048).

Summary: Background: The benefit of Glucagon-like Peptide-1 (GLP-1) receptor agonists (RAs) in weight reduction against potential harms remains unclear. This study aimed at evaluating the benefit-harm balance of initiating GLP-1 RAs versus placebo for weight loss in people living with overweight and obesity but without diabetes. Methods: We performed benefit-harm balance modelling, which will be updated as new evidence emerges. We searched for randomised controlled trials (RCTs) in PubMed, controlled trials registry, drug approval and regulatory documents, and outcome preference weights as of April 10, 2024. We synthesize data using pairwise meta-analysis to estimate the effect of GLP-1 RAs to inform the benefit-harm balance modelling. We predicted the absolute effects of the positive and negative outcomes over 1 and 2 years of treatment using exponential models. We applied preference weights to the outcomes, ranging from 0 for least concerning to 1.0 for most concerning. We then calculated whether the benefit of achieving 5% and 10% weight loss outweighed the harms on a common scale. The analyses accounted for the statistical uncertainties of treatment effects, preference weights, and outcome risks. Findings: We included 8 RCTs involving 8847 participants. The pooled average age was 46.7 years, with the majority being women (74%) and people living with obesity (96%). Of 1000 persons treated with GLP-1 RAs for 2 years, 375 (95% confidence interval 352 to 399) achieved a 10% weight loss, and 318 (296 to 339) achieved a 5% weight loss compared to those treated with placebo. Several harm outcomes were more frequent in the GLP-1 RA group, including 41 abdominal pain events per 1000 persons over 2 years (19 to 69), cholelithiasis (8, 1 to 21), constipation (118, 78 to 164), diarrhoea (100, 42 to 173), alopecia (57, 10 to 176), hypoglycaemia (17, 1 to 68), injection site reactions (4, −3 to 19), and vomiting (110, 80 to 145) among others. Achieving a 10% weight loss with GLP-1 RA therapy outweighed the cumulative harms, with a net benefit probability of 0.97 at year 1 and 0.91 at year 2. The absolute net benefit was equivalent to 104 (100 to 112) per 1000 persons achieving a 10% weight loss over 2 years without experiencing any worrisome harm. A 5% weight loss did not show a net benefit, with probabilities of 0.13 and 0.01 at year 1 and year 2, respectively. However, these benefits were sensitive to preference weights, suggesting that even a 5% weight loss could be net beneficial for individuals with less concern about harm outcomes. The net benefit for a 10% weight loss was highest for semaglutide, followed by liraglutide and tirzepatide, with 2-year probabilities of 0.96, 0.72, and 0.60, respectively. Interpretation: The benefit of GLP-1 RAs exceeded the harms for weight loss in the first 2 years of treatment, yet the net benefit was dependent on individual’ treatment goals (10% or 5% weight loss) and willingness to accept harms in pursuit of weight loss. This implies that treatment decisions have to be personalized to individuals to optimize benefits and reduce harms and overuse of treatments. Due to varying evidence, especially regarding harm outcomes across studies, it is necessary to continuously update and monitor the benefit-harm balance of GLP-1 RAs. Funding: SNSF and LOOP Zurich.

Abstract The 9th Cardiovascular Outcome Trial (CVOT) Summit: Congress on Cardiovascular, Kidney, and Metabolic Outcomes was held virtually on November 30-December 1, 2023. This reference congress served as a platform for in-depth discussions and exchange on recently completed outcomes trials including dapagliflozin (DAPA-MI), semaglutide (SELECT and STEP-HFpEF) and bempedoic acid (CLEAR Outcomes), and the advances they represent in reducing the risk of major adverse cardiovascular events (MACE), improving metabolic outcomes, and treating obesity-related heart failure with preserved ejection fraction (HFpEF). A broad audience of endocrinologists, diabetologists, cardiologists, nephrologists and primary care physicians participated in online discussions on guideline updates for the management of cardiovascular disease (CVD) in diabetes, heart failure (HF) and chronic kidney disease (CKD); advances in the management of type 1 diabetes (T1D) and its comorbidities; advances in the management of CKD with SGLT2 inhibitors and non-steroidal mineralocorticoid receptor antagonists (nsMRAs); and advances in the treatment of obesity with GLP-1 and dual GIP/GLP-1 receptor agonists. The association of diabetes and obesity with nonalcoholic steatohepatitis (NASH; metabolic dysfunction-associated steatohepatitis, MASH) and cancer and possible treatments for these complications were also explored. It is generally assumed that treatment of chronic diseases is equally effective for all patients. However, as discussed at the Summit, this assumption may not be true. Therefore, it is important to enroll patients from diverse racial and ethnic groups in clinical trials and to analyze patient-reported outcomes to assess treatment efficacy, and to develop innovative approaches to tailor medications to those who benefit most with minimal side effects. Other keys to a successful management of diabetes and comorbidities, including dementia, entail the use of continuous glucose monitoring (CGM) technology and the implementation of appropriate patient-physician communication strategies. The 10th Cardiovascular Outcome Trial Summit will be held virtually on December 5–6, 2024 ( http://www.cvot.org ).

The factors determining the response to treatment with glucagon-like peptide-1 receptor agonists (GLP-1- RAs) have not been clarified. The present study investigated the association between polymorphisms in TCF7L2, CTRB1/2, and GLP-1 R genes and response to GLP-1 RAs regarding glycemic control and weight loss among Greek patients with type 2 diabetes mellitus (T2DM). Patients (n = 191) treated with GLP-1 RAs for at least 6 months were included. Participants were genotyped for TCF7L2 rs7903146 (C>T), CTRB1/2 rs7202877 (T>G) and GLP-1 R rs367543060 (C>T) polymorphisms. Clinical and laboratory parameters were measured before, 3, and 6 months after treatment initiation. The patients were classified into responders and non-responders according to specific criteria. Carriers of at least one rs7903146 'T' allele and rs7202877 'G' allele presented similar glucose control and weight loss response to GLP-1 RAs with the respective homozygous wild-type genotypes [odds ratio (OR): 1.08, 95% confidence interval (CI): 0.5, 2.31, p = 0.85 and OR: 1.35, 95% CI: 0.66, 2.76, p = 0.42; OR: 1.4, 95% CI: 0.56, 3.47, p = 0.47 and OR: 1.28, 95% CI: 0.55, 2.98, p = 0.57, respectively]. Regarding the GLP-1 R polymorphism, all participants were homozygous for the wild-type allele; thus, no comparisons were feasible. Female sex (p = 0.03) and lower baseline weight (p = 0.024) were associated with an improved glycemic and weight loss response, respectively. There is no evidence suggesting a role for the variants studied in response to GLP-1 RA therapy in people with T2DM. However, specific demographic and clinical factors may be related to a better response to treatment with these agents. [ABSTRACT FROM AUTHOR]

Infertility is a modern health problem. Obesity is another expanding health issue associated with chronic diseases among which infertility is also included. This review will focus on the effects of weight loss by medical therapy on fertility regarding reproductive hormonal profile, ovulation rates, time to pregnancy, implantation rates, pregnancy rates, normal embryo development, and live birth rates. We comprised medicine already used for weight loss, such as orlistat and metformin, and emerging medical treatments, such as Glucagon-Like Peptide-1 receptor agonists (GLP-1 RA). Their use is not recommended during a planned pregnancy, and they should be discontinued in such cases. The main outcomes of this literature review are the following: modest weight loss after medication and the duration of the treatment are important factors for fertility improvement. The fecundity outcomes upon which medical-induced weight loss provides significant results are the female reproductive hormonal profile, menstrual cyclicity, ovulation and conception rates, and pregnancy rates. Regarding the male reproductive system, the fertility outcomes that feature significant alterations after medically induced weight loss are as follows: the male reproductive hormonal profile, sperm motility, movement and morphology, weight of reproductive organs, and sexual function. The newer promising GLP-1 RAs show expectations regarding fertility improvement, as they have evidenced encouraging effects on improving ovulation rates and regulating the menstrual cycle. However, more human studies are needed to confirm this. Future research should aim to provide answers about whether medical weight loss therapies affect fertility indirectly through weight loss or by a possible direct action on the reproductive system.

Abstract Aim To compare the cardiovascular preventive effect associated with glucagon‐like‐peptide‐1 receptor agonists (GLP‐1 RA) versus dipeptidyl peptidase‐4 inhibitors (DPP‐4i) according to the achieved target level of glycated hemoglobin (HbA1c). Methods We used retrospective Danish registries to include type 2 diabetes patients already in metformin treatment initiating GLP‐1 RA or DPP‐4i between 2007 and 2021. Patients were included 6 months after GLP‐1 RA or DPP‐4i initiation. The last available HbA1c measurement before inclusion was collected. The achieved HbA1c level was categorized according to a target level below or above 53 mmol/mol (7%). The primary outcome was a composite of nonfatal myocardial infarction, nonfatal stroke, and all‐cause death. We used a multivariable Cox proportional hazard model to estimate the effect of HbA1c levels on the outcome among GLP‐1 RA users compared to DPP‐4i users. Results The study included 13 634 GLP‐1 RA users (median age 56.9, interquartile range [IQR]: 48.5–65.5; 53% males) and 39 839 DPP‐4i users (median age 63.4, IQR: 54.6–71.8; 61% males). The number of GLP‐1 RA and DPP‐4i users according to achieved HbA1c levels were as follows: HbA1c ≤ 53 mmol/mol (≤7.0%): 3026 (22%) versus 4824 (12%); HbA1c > 53 mmol/mol (>7.0%): 6577 (48%) versus 17 508 (44%); missing HbA1c: 4031 (30%) versus 17 507 (44%). During a median follow‐up of 5 years (IQR: 2.6–5.0), 954 GLP‐1 RA users experienced the primary outcome compared to 7093 DPP‐4i users. The 5‐year risk (95% confidence interval [CI]) of the outcome associated with GLP1‐RA versus DPP‐4i according to HbA1c categories was as follows: HbA1c ≤ 53 mmol/mol: 10.3% (8.2–12.3) versus 24.3% (22.7–25.8); HbA1c > 53 mmol/mol: 16.0% (14.3–17.6) versus 21.1% (20.3–21.9); missing HbA1c: 17.1% (15.7–18.5) versus 25.6% (24.9–26.3). The preventive effect associated with GLP‐1 RA versus DPP‐4i was significantly enhanced when achieving lower HbA1c levels: HbA1c ≤ 53 mmol/mol: 0.65 (0.52–0.80); HbA1c > 53 mmol/mol: 0.92 (0.83–1.03); missing HbA1c: 0.92 (0.84–1.02) (p value for interaction

Summary: Background: Sodium-Glucose Cotransporter 2 Inhibitors (SGLT2i) and Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RA) improve cardiorenal outcomes in patients with type 2 diabetes. Equitable use of SGLT2i and GLP-1 RA has the potential to reduce racial and ethnic health disparities. We evaluated trends in pharmacy dispensing of SGLT2i and GLP-1 RA by race and ethnicity. Methods: Retrospective cohort study of patients (≥18 years) with type 2 diabetes using 2014–2022 electronic health record data from six US care delivery systems. Entry was at earliest pharmacy dispensing of any type 2 diabetes medication. We used multivariable logistic regression to evaluate the association between pharmacy dispensing of SGLT2i and GLP1-RA and race and ethnicity. Findings: Our cohort included 687,165 patients (median 6 years of dispensing data; median 60 years; 0.3% American Indian/Alaska Native (AI/AN), 16.6% Asian, 10.5% Black, 1.4% Hawaiian or Pacific Islander (HPI), 31.1% Hispanic, 3.8% Other, and 36.3% White). SGLT2i was lower for AI/AN (OR 0.80, 95% confidence interval 0.68–0.94), Black (0.89, 0.86–0.92) and Hispanic (0.87, 0.85–0.89) compared to White patients. GLP-1 RA was lower for AI/AN (0.78, 0.63–0.97), Asian (0.50, 0.48–0.53), Black (0.86, 0.83–0.90), HPI (0.52, 0.46–0.57), Hispanic (0.69, 0.66–0.71), and Other (0.78, 0.73–0.83) compared to White patients. Interpretation: Dispensing of SGLT2is, and GLP-1 RAs was lower in minority group patients. There is a need to evaluate approaches to increase use of these cardiorenal protective drugs in patients from racial and ethnic minority groups with type 2 diabetes to reduce adverse cardiorenal outcomes and improve health equity.

Summary: Background: Type 2 diabetes (T2DM) remains a challenge to treat despite the expansion of various therapeutic classes. Visepegenatide (PB-119) is a once a week, subcutaneous, glucagon-like peptide-1 receptor agonist (GLP-1 RA) injection without the requirement of dose titration that has shown glycaemic control and safety profile in two phase 2 studies conducted in China and the United States, respectively. The aim of this study was to evaluate the efficacy and safety of visepegenatide as a monotherapy in treatment-naïve patients with T2DM. Methods: This was a multicentre, double-blind, parallel, placebo-controlled, phase 3 trial conducted in 30 centres in China. Adult participants (aged 18–75 years) with T2DM, glycated haemoglobin (HbA1c) of 7.5%–11.0% [58.47–96.73 mmol/mol], body mass index (BMI) of 18–40 kg/m2, and who had been treated with diet and exercise alone for at least 8 weeks before the screening visit were eligible for enrolment. After a 4-week placebo injection run-in period, participants with HbA1c of 7.0%–10.5% [53.0–91.3 mmol/mol] and fasting plasma glucose (FPG)

How do we assess the overall benefit and value of GLP1-RAs? Current clinical trials often focus narrowly on individual atherosclerotic cardiovascular endpoints like MACE, potentially missing broader GLP-1 RA benefits across multiple comorbidities. Herein, we set out a framework for expanding outcome analyses in large trials that we believe will provide a more holistic understanding of GLP-1 RA benefits across the cardio-kidney-metabolic (CKM) spectrum, guiding patient care, guidelines, and insurance coverage decisions.

Studies have shown that antidiabetic drugs can alter the gut microbiota. The hypoglycemic effects of the drugs can be attributed in part to certain species in the gut microbiome that help the drugs work more effectively. In addition, increasing energy expenditure via the induction of adipose tissue browning has become an appealing strategy to treat obesity and associated metabolic complications. Currently, glucagon‐like peptide‐1 receptor agonist (GLP‐1 RA) treatment for metabolic disorders such as obesity and type 2 diabetes has been widely studied. To determine the mechanism of a long‐acting GLP‐1 RA affects adipose tissue browning and the gut microbiome, we treated high‐fat diet mice with GLP‐1 RA and demonstrated that the drug can regulate adipose tissue browning. 16S rRNA and untargeted metabolomics assays suggested that it increased the abundance of bacterium Lactobacillus reuteri and decreased serum ceramide levels in mice. L. reuteri was negatively correlated with ceramide. We found that the mechanism of ceramide decline was alkaline ceramidase 2 (Acer2) overexpression. Moreover, L. reuteri can play a therapeutic synergistic role with GLP‐1 RA, suggesting that gut microbiota can be used as a part of the treatment of diabetes. [ABSTRACT FROM AUTHOR]

The glucagon-like peptide 1 receptor agonists, together with sodium-glucose cotransporter-2 inhibitors, are antidiabetic drugs known for their beneficial effects on the cardiovascular system; many phase 3 trials also support this conclusion. However, it can be thought that they may cause an increase in the risk of tachyarrhythmia due to the stimulation of their receptors in the sympathetic nervous system and sinoatrial cells. We report a case of a 71-year-old woman with no history of arrhythmia who presented with new-onset atrial fibrillation after an exenatide injection during clinical follow-up. [ABSTRACT FROM AUTHOR]

Aims/hypothesis: Insulin is the primary treatment for type 1 diabetes. However, alternative glucose-lowering therapies are used adjunctively, but importantly are off-label in type 1 diabetes. Little work has previously been undertaken to evaluate safety with long-term efficacy and cardio-renal benefits of such therapies. We sought to investigate the real-world impact of sodium–glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy in individuals with type 1 diabetes in relation to effect on blood glucose levels, adverse events and cardio-renal outcomes. Methods: We performed a retrospective cohort study of all patients aged 18 or over with type 1 diabetes on the TriNetX platform, a global collaborative network providing access to real-time, anonymised medical records. We included patients who had been treated with an SGLT2i or GLP-1 RA for at least 6 months and analysed the efficacy, safety and cardio-renal outcomes 5 years after initiation of therapy. Results: We identified 196,691 individuals with type 1 diabetes, 13% of whom were treated with adjunctive glucose-lowering therapy in addition to insulin. Included in the core analysis were 1822 patients treated with a GLP-1 RA and 992 individuals treated with an SGLT2i. Both agents provided clinically meaningful reductions in HbA1c (−2.6 mmol/mol [−0.2%] with SGLT2i and −5.4 mmol/mol [−0.5%] with GLP-1 RA). The SGLT2i treated cohort showed preservation of eGFR over a 5-year period compared with the GLP-1 RA treated cohort (+3.5 ml/min per 1.73 m2 vs −7.2 ml/min per 1.73 m2, respectively), including patients with established chronic kidney disease (CKD). The SGLT2i treated cohort experienced higher rates of diabetic ketoacidosis (DKA) (RR 2.08 [95% CI 1.05, 4.12] p=0.0309) and urinary tract infection/pyelonephritis (RR 2.27 [95% CI 1.12, 4.55] p=0.019) compared with the GLP-1 RA treated cohort. However, the SGLT2i treated cohort were less likely to develop heart failure (RR 0.44 [95% CI 0.23, 0.83] p=0.0092), CKD (RR 0.49 [95% CI 0.28, 0.86] p=0.0118) and be hospitalised for any cause (RR 0.59 [95% CI 0.46, 0.76] p≤0.0001) when compared with the GLP-1 RA treated cohort. Conclusions/interpretation: Both SGLT2is and GLP-1 RAs have potential benefits as adjunctive agents in type 1 diabetes. SGLT2is provide cardio-renal benefits, despite an increase in the risk of DKA and urinary tract infection compared with GLP-1 RA therapy. Long-term evaluation of the efficacy and safety of these adjunctive therapies is required to guide their use in individuals with type 1 diabetes. [ABSTRACT FROM AUTHOR]

Abstract Background In clinical trials enrolling patients with type 2 diabetes (T2D) at high cardiovascular risk, many glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improved albuminuria status and possibly mitigated kidney function loss. However, limited data are available regarding the effects of GLP-1 RAs on albuminuria status and kidney function in real-world settings, including populations with a lower baseline cardiovascular and kidney risk. We assessed the association of GLP-1 RAs initiation with long-term kidney outcomes in the Maccabi Healthcare Services database, Israel. Methods Adults with T2D treated with ≥ 2 glucose-lowering agents who initiated GLP-1 RAs or basal insulin from 2010 to 2019 were propensity-score matched (1:1) and followed until October 2021 (intention-to-treat [ITT]). In an as-treated (AT) analysis, follow-up was also censored at study-drug discontinuation or comparator-initiation. We assessed the risk of a composite kidney outcome, including confirmed ≥ 40% eGFR loss or end-stage kidney disease, and the risk of new macroalbuminuria. Treatment-effect on eGFR slopes was assessed by fitting a linear regression model per patient, followed by a t-test to compare the slopes between the groups. Results Each propensity-score matched group constituted 3424 patients, 45% women, 21% had a history of cardiovascular disease, and 13.9% were treated with sodium-glucose cotransporter-2 inhibitors at baseline. Mean eGFR was 90.6 mL/min/1.73 m2 (SD 19.3) and median UACR was 14.6 mg/g [IQR 0.0–54.7]. Medians follow-up were 81.1 months (ITT) and 22.3 months (AT). The hazard-ratios [95% CI] of the composite kidney outcome with GLP-1 RAs versus basal insulin were 0.96 [0.82–1.11] (p = 0.566) and 0.71 [0.54–0.95] (p = 0.020) in the ITT and AT analyses, respectively. The respective HRs for first new macroalbuminuria were 0.87 [0.75–0.997] and 0.80 [0.64–0.995]. The use of GLP-1 RA was associated with a less steep eGFR slope compared with basal insulin in the AT analysis (mean annual between-group difference of 0.42 mL/min/1.73 m2/year [95%CI 0.11–0.73]; p = 0.008). Conclusion Initiation of GLP-1 RAs in a real-world setting is associated with a reduced risk of albuminuria progression and possible mitigation of kidney function loss in patients with T2D and mostly preserved kidney function.

Objective: Type 2 diabetes (T2D) is linked to metabolic, mitochondrial and inflammatory alterations, atherosclerosis development and cardiovascular diseases (CVDs). The aim was to investigate the potential therapeutic benefits of GLP-1 receptor agonists (GLP-1 RA) on oxidative stress, mitochondrial respiration, leukocyte-endothelial interactions, inflammation and carotid intima–media thickness (CIMT) in T2D patients. Research design and methods: Type 2 diabetic patients (255) and control subjects (175) were recruited, paired by age and sex, and separated into two groups: without GLP-1 RA treatment (196) and treated with GLP-1 RA (59). Peripheral blood polymorphonuclear leukocytes (PMNs) were isolated to measure reactive oxygen species (ROS) production by flow cytometry and oxygen consumption with a Clark electrode. PMNs were also used to assess leukocyte-endothelial interactions. Circulating levels of adhesion molecules and inflammatory markers were quantified by Luminex's technology, and CIMT was measured as surrogate marker of atherosclerosis. Results: Treatment with GLP-1 RA reduced ROS production and recovered mitochondrial membrane potential, oxygen consumption and MPO levels. The velocity of leukocytes rolling over endothelial cells increased in PMNs from GLP-1 RA-treated patients, whereas rolling and adhesion were diminished. ICAM-1, VCAM-1, IL-6, TNFα and IL-12 protein levels also decreased in the GLP-1 RA-treated group, while IL-10 increased. CIMT was lower in GLP-1 RA-treated T2D patients than in T2D patients without GLP-1 RA treatment. Conclusions: GLP-1 RA treatment improves the redox state and mitochondrial respiration, and reduces leukocyte-endothelial interactions, inflammation and CIMT in T2D patients, thereby potentially diminishing the risk of atherosclerosis and CVDs.

(1) Background: Oral semaglutide represents the first oral GLP-1 RA approved for the treatment of type 2 diabetes mellitus (T2DM). This real-world retrospective study aimed at evaluating its effectiveness and tolerability in the treatment of patients with T2DM when patients switched from a glucose-lowering agent to it and when it was added to the usual therapy. (2) Methods: Adult patients with T2DM taking oral semaglutide and followed in the ASUGI Diabetes Center were identified with the use of electronic medical records between October 2022 and May 2023. (3) Results: A total of 129 patients were recruited. The median follow-up was 6 months. Be it as a switchover or as an add-on therapy, oral semaglutide significantly reduced HbA1c and BMI. Switching from DPPIV inhibitors to oral semaglutide was associated with a significant reduction in HbA1c and BMI, switching from SGLT2 inhibitors was associated with a significant reduction in HbA1c, and switching from sulphonylureas was associated with a significant reduction in BMI. The median HbA1c change was associated with baseline HbA1c. SBP significantly decreased in the add-on group. Oral semaglutide was well tolerated. (4) Conclusions: This study shows that in the real-world setting, oral semaglutide is effective and safe as a switchover or as an add-on therapy for the treatment of T2DM. [ABSTRACT FROM AUTHOR]

Introduction: As new glucagon-like peptide 1 receptor agonist (GLP-1 RA) formulations are available, the aim of this study was to understand dulaglutide and subcutaneous (s.c.) semaglutide dosing patterns in people with type 2 diabetes mellitus (T2DM) in the UK and Germany as well as oral semaglutide in the UK. Methods: Adults with evidence of T2DM and a prescription of dulaglutide or semaglutide between August 2020 and December 2021 were identified using the IQVIA Longitudinal Prescription Data (LRx). Patients were divided into cohort 1 (incident users) and cohort 2 (prevalent users) based on previous exposure to GLP-1 RAs and were followed up to 12 months post-index. Results: During the patient selection window in Germany and the UK, 368,320 and 123,548 patients respectively received at least one prescription of a study GLP-1 RA. Among dulaglutide users in Germany at 12 months post-index, the 1.5-mg dosage formulation was the most common for both cohort 1 (65.6%) and 2 (71.2%). Among s.c. semaglutide users at 12 months post-index, 39.2% and 58.4% of cohort 1 received 0.5 mg and 1.0 mg, respectively. In the UK, at 12 months post-index, the most common dulaglutide dosage formulation was 1.5 mg (71.7% cohort 1 and 80.9% cohort 2). Among s.c. semaglutide users at 12 months post-index, 0.5- and 1.0-mg formulations were the most common for both cohort 1 (38.9% and 56.0%, respectively) and cohort 2 (29.5% and 67.1%, respectively). Prescribing of the more recently introduced 3.0- and 4.5-mg formulations for dulaglutide and oral semaglutide was also reported in the study. Conclusion: Dosing patterns of GLP-1 RAs, although similar between the UK and Germany, were heterogeneous over time. Given that the higher dulaglutide doses and oral semaglutide were recently introduced to the market, additional real-world evidence studies which include clinical outcomes is required.

Background: The management of antidiabetic therapy in people with type 2 diabetes (T2D) has evolved beyond glycemic control. In this context, Brazil and Portugal defined a joint panel of four leading diabetes societies to update the guideline published in 2020. Methods: The panelists searched MEDLINE (via PubMed) for the best evidence from clinical studies on treating T2D and its cardiorenal complications. The panel searched for evidence on antidiabetic therapy in people with T2D without cardiorenal disease and in patients with T2D and atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), or diabetic kidney disease (DKD). The degree of recommendation and the level of evidence were determined using predefined criteria. Results and conclusions: All people with T2D need to have their cardiovascular (CV) risk status stratified and HbA1c, BMI, and eGFR assessed before defining therapy. An HbA1c target of less than 7% is adequate for most adults, and a more flexible target (up to 8%) should be considered in frail older people. Non-pharmacological approaches are recommended during all phases of treatment. In treatment naïve T2D individuals without cardiorenal complications, metformin is the agent of choice when HbA1c is 7.5% or below. When HbA1c is above 7.5% to 9%, starting with dual therapy is recommended, and triple therapy may be considered. When HbA1c is above 9%, starting with dual therapyt is recommended, and triple therapy should be considered. Antidiabetic drugs with proven CV benefit (AD1) are recommended to reduce CV events if the patient is at high or very high CV risk, and antidiabetic agents with proven efficacy in weight reduction should be considered when obesity is present. If HbA1c remains above target, intensification is recommended with triple, quadruple therapy, or even insulin-based therapy. In people with T2D and established ASCVD, AD1 agents (SGLT2 inhibitors or GLP-1 RA with proven CV benefit) are initially recommended to reduce CV outcomes, and metformin or a second AD1 may be necessary to improve glycemic control if HbA1c is above the target. In T2D with HF, SGLT2 inhibitors are recommended to reduce HF hospitalizations and mortality and to improve HbA1c. In patients with DKD, SGLT2 inhibitors in combination with metformin are recommended when eGFR is above 30 mL/min/1.73 m2. SGLT2 inhibitors can be continued until end-stage kidney disease.

Highlights This study demonstrates that initiation of glucagon‐like peptide‐1 receptor agonists among individuals with type 2 diabetes (T2D), including those with concomitant atherosclerotic cardiovascular disease (ASCVD), has remained low in the United States between 2014 and 2019, despite clinical evidence supporting their use for cardiovascular risk reduction. These findings add to the existing literature to highlight a gap in adherence to current practice guidelines, which suggests that most patients with T2D and ASCVD in the United States may not be receiving optimal risk‐reducing therapies.

The occurrence and development of coronary heart disease (CHD) are closely linked to fluctuations in blood glucose levels. While the efficacy of intensified treatment guided by HbA1c levels remains uncertain for individuals with diabetes and CHD, this review summarizes the findings and conclusions regarding HbA1c in the context of CHD. Our review showed a curvilinear correlation between regulated level of HbA1c and therapeutic effectiveness of intensified glycemic control among patients with type 2 diabetes and coronary heart disease. It is necessary to optimize the dynamic monitoring indicators of HbA1c, combine genetic profiles, haptoglobin phenotypes for example and select more suitable hypoglycemic drugs to establish more appropriate glucose-controlling guideline for patients with CHD at different stage of diabetes.

Background: In clinical trials enrolling patients with type 2 diabetes (T2D) at high cardiovascular risk, many glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improved albuminuria status and possibly mitigated kidney function loss. However, limited data are available regarding the effects of GLP-1 RAs on albuminuria status and kidney function in real-world settings, including populations with a lower baseline cardiovascular and kidney risk. We assessed the association of GLP-1 RAs initiation with long-term kidney outcomes in the Maccabi Healthcare Services database, Israel. Methods: Adults with T2D treated with ≥ 2 glucose-lowering agents who initiated GLP-1 RAs or basal insulin from 2010 to 2019 were propensity-score matched (1:1) and followed until October 2021 (intention-to-treat [ITT]). In an as-treated (AT) analysis, follow-up was also censored at study-drug discontinuation or comparator-initiation. We assessed the risk of a composite kidney outcome, including confirmed ≥ 40% eGFR loss or end-stage kidney disease, and the risk of new macroalbuminuria. Treatment-effect on eGFR slopes was assessed by fitting a linear regression model per patient, followed by a t-test to compare the slopes between the groups. Results: Each propensity-score matched group constituted 3424 patients, 45% women, 21% had a history of cardiovascular disease, and 13.9% were treated with sodium-glucose cotransporter-2 inhibitors at baseline. Mean eGFR was 90.6 mL/min/1.73 m2 (SD 19.3) and median UACR was 14.6 mg/g [IQR 0.0–54.7]. Medians follow-up were 81.1 months (ITT) and 22.3 months (AT). The hazard-ratios [95% CI] of the composite kidney outcome with GLP-1 RAs versus basal insulin were 0.96 [0.82–1.11] (p = 0.566) and 0.71 [0.54–0.95] (p = 0.020) in the ITT and AT analyses, respectively. The respective HRs for first new macroalbuminuria were 0.87 [0.75–0.997] and 0.80 [0.64–0.995]. The use of GLP-1 RA was associated with a less steep eGFR slope compared with basal insulin in the AT analysis (mean annual between-group difference of 0.42 mL/min/1.73 m2/year [95%CI 0.11–0.73]; p = 0.008). Conclusion: Initiation of GLP-1 RAs in a real-world setting is associated with a reduced risk of albuminuria progression and possible mitigation of kidney function loss in patients with T2D and mostly preserved kidney function.

Alterations of endothelial function, inflammatory activation, and nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway are involved in the pathophysiology of heart failure. Metabolic alterations have been studied in the myocardium of heart failure (HF) patients; alterations in ketone body and amino acid/protein metabolism have been described in patients affected by HF, as well as mitochondrial dysfunction and other modified metabolic signaling. However, their possible contributions toward cardiac function impairment in HF patients are not completely known. Recently, sodium-glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) have emerged as a new class of drugs designed to treat patients with type 2 diabetes (T2D), but have also been shown to be protective against HF-related events and CV mortality. To date, the protective cardiovascular effects of these drugs in patients with and without T2D are not completely understood and several mechanisms have been proposed. In this review, we discuss on vascular and metabolic effects of SGLT2i and GLP-1 in HF patients. [ABSTRACT FROM AUTHOR]

As the pathophysiologic mechanisms of type 2 diabetes mellitus (T2DM) are discovered, there is a switch from glucocentric to a more comprehensive, patient-centered management. The holistic approach considers the interlink between T2DM and its complications, finding the best therapies for minimizing the cardiovascular (CV) or renal risk and benefitting from the treatment's pleiotropic effects. Sodium-glucose cotransporter 2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) fit best in the holistic approach because of their effects in reducing the risk of CV events and obtaining better metabolic control. Additionally, research on the SGLT-2i and GLP-1 RA modification of gut microbiota is accumulating. The microbiota plays a significant role in the relation between diet and CV disease because some intestinal bacteria lead to an increase in short-chain fatty acids (SCFA) and consequent positive effects. Thus, our review aims to describe the relation between antidiabetic non-insulin therapy (SGLT-2i and GLP-1 RA) with CV-proven benefits and the gut microbiota in patients with T2DM. We identified five randomized clinical trials including dapagliflozin, empagliflozin, liraglutide, and loxenatide, with different results. There were differences between empagliflozin and metformin regarding the effects on microbiota despite similar glucose control in both study groups. One study demonstrated that liraglutide induced gut microbiota alterations in patients with T2DM treated initially with metformin, but another failed to detect any differences when the same molecule was compared with sitagliptin. The established CV and renal protection that the SGLT-2i and GLP-1 RA exert could be partly due to their action on gut microbiota. The individual and cumulative effects of antidiabetic drugs on gut microbiota need further research. [ABSTRACT FROM AUTHOR]

Obesity remains a major public health problem, affecting almost half of adults in the United States. Increased risk of cardiovascular disease (CVD) and CVD mortality are major obesity‐related complications, and management guidelines now recommend weight loss as a key strategy for the primary prevention of CVD in patients with overweight or obesity. The recently demonstrated efficacy of some pharmacologic therapies for chronic weight management may encourage health care professionals to recognize obesity as a treatable serious chronic disease and motivate patients to re‐engage with weight loss when previous attempts have been ineffective or unsustainable. This review article summarizes the benefits and challenges associated with lifestyle changes, bariatric surgery, and historical pharmacologic interventions in the treatment of obesity, and focuses on the current evidence for the efficacy and safety of the newer glucagon‐like peptide‐1 receptor agonist medications in the management of obesity and potential reduction of CVD risk. We conclude that the available evidence demonstrates glucagon‐like peptide‐1 receptor agonists should be strongly considered in clinical practice for the treatment of obesity and reduction of CVD risk in people with type 2 diabetes. If ongoing research proves glucagon‐like peptide‐1 receptor agonists to be effective in reducing the risk of CVD onset in patients with obesity, irrespective of type 2 diabetes status, it will herald a new treatment paradigm in this setting, and now is the time for health care professionals to better recognize the benefits of these agents.
