RESUMEN
Obesity and type 2 diabetes mellitus (T2DM) present major global health challenges, with an increasing prevalence worldwide. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have emerged as a pivotal treatment option for both conditions, demonstrating efficacy in blood glucose management, weight reduction, cardiovascular disease prevention, and kidney health improvement. GLP-1, an incretin hormone, plays a crucial role in glucose metabolism and appetite regulation, influencing insulin secretion, insulin sensitivity, and gastric emptying. The therapeutic use of GLP-1RAs has evolved significantly, offering various formulations that provide different efficacy, routes of administration, and flexibility in dosing. These agents reduce HbA1c levels, facilitate weight loss, and exhibit cardiovascular protective effects, making them an integral component of T2DM and obesity management. This review will discuss the currently approved medication for T2DM and obesity, and will also highlight the advent of novel agents which are dual and triple hormonal agonists which represent the future direction of incretin-based therapy.

RESUMEN
Type 2 Diabetes (T2D) is a chronic disease with increasing incidence and prevalence and serious chronic complications, especially from cardiovascular system. However, other organs can be affected too. Several studies have associated T2D, especially when poorly controlled, with multiple pulmonary diseases. T2D is a common comorbidity among patients with asthma, Chronic Obstructive Pulmonary Disease (COPD), and Obstructive Sleep Apnea Syndrome (OSAS), and it is related to higher respiratory infection incidence, prevalence and severity. Glucagon-like peptide-1 receptor agonists (GLP-1RA) and Sodium-glucose co-transporter-2 inhibitors (SGLT-2i) are novel antihyperglycaemic agents with established cardiovascular benefits. There are also limited studies indicating their potential benefit in respiratory function. The aim of this article is to review data on the impact of GLP-1RA and SGLT-2i on respiratory function and describe the possible clinical benefits. Key findings indicate that GLP-1RA significantly improve lung function in patients with COPD, evidenced by improvements in spirometry measurements. Additionally, both GLP-1RA and SGLT-2i are associated with a decreased risk of severe and moderate exacerbations in COPD patients and have shown potential in reducing the incidence of respiratory disorders, including asthma and pneumonia. The mechanisms underlying these benefits are not yet fully understood and include multiple effects, such as anti-inflammatory action and oxidative stress reduction.
RESUMEN
Cardiovascular disease (CVD) claims millions of lives every year, with atherosclerotic cardiovascular disease (ASCVD) being the main cause. ASCVD treatment includes drug therapy, lifestyle intervention, and Percutaneous Coronary Intervention (PCI) all of which significantly enhance cardiovascular function and reduce mortality. However, hyperplasia can lead to vascular obstruction, worsen angina symptoms, or even cause heart disease, affecting patients' long-term prognosis. Therefore, finding effective ways to combat hyperplasia is crucial for cardiovascular therapy. In recent years, ferroptosis has gained attention as a new form of cell death closely associated with several diseases, including cardiovascular diseases. It involves complex metabolic processes critical for cellular homeostasis and normal function. Abnormal proliferation and phenotypic transformation of vascular smooth muscle cells (VSMC) are crucial mechanisms underlying cardiovascular disease development. Inhibiting ferroptosis in VSMC has the potential to significantly reduce neointima proliferation. Glucagon-like peptide-1 receptor agonist (GLP-1RA) constitutes a widely employed class of hypoglycemic agents with direct implications for the cardiovascular system, mitigating adverse cardiovascular events. Research indicates that the stimulation of GLP-1 holds promise as a therapeutic strategy in mitigating cardiovascular events such as restenosis. Hence, investigating the potential of GLP-1RA as a treatment option for cardiovascular ailments carries immense clinical significance.
RESUMEN
Cardiovascular risks and complications remain elevated in patients with type 2 diabetes even after appropriate control of contributing factors like glycemic control, hypertension, and lipid profile. More efficient methods are needed to address this issue in type 2 diabetics. Newer drugs like glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown a cardioprotective effect in addition to glycemic control. This systematic review aims to study the latest literature findings on the cardiovascular effects of GLP-1 RAs in patients with type 2 diabetes. We used PubMed, Google Scholar, Science Direct, and Biomed Central databases for our data collection. Our review adheres to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The outcomes evaluated in the review include major adverse cardiovascular events (MACE), heart failure, stroke, all-cause mortality, and effects on cardiovascular risk factors. After careful inspection and quality check, we included 14 articles in the systematic review. GLP-1 RAs were associated with a significant reduction in cardiovascular mortality, all-cause mortality, nonfatal myocardial infarction (MI), and nonfatal stroke, especially in patients with existing cardiovascular risk factors. However, more evidence is required to determine if these benefits extend to those without such risk factors. Limited data suggest that GLP-1 RAs might have a protective effect on arrhythmias, but this area needs further investigation. Despite their potential, several barriers hinder the widespread use of GLP-1 RAs. In conclusion, GLP-1 RAs significantly reduce cardiovascular mortality, all-cause mortality, nonfatal MI, and stroke, with minor effects on hospitalization due to heart failure. Benefits are greater in patients with cardiovascular risk factors. A comprehensive, multilevel approach to policy development and implementation is necessary to optimize the use of these medications in eligible populations.
RESUMEN
BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), particularly semaglutide, have become the leading anti-obesity drugs for adults, and a similar trend may follow in adolescents with its recent approval for this age group. However, there is a lack of comparative analysis on the weight loss effects and safety of GLP-1 RAs in obese or overweight pediatric and adolescent populations, especially those who are non-diabetic. This systematic review and meta-analysis aim to provide current evidence on the efficacy and safety of GLP-1 RAs as an anti-obesity treatment in obese or overweight non-diabetic pediatric and adolescent populations. METHOD: We searched electronic databases from inception until January 2024 for randomized controlled trials (RCTs) that analyzed the weight loss effect of GLP-1 receptor agonists in adolescents with obesity or overweight without diabetes mellitus. Search results were screened, and eligible studies were included to perform a systematic review and meta-analysis using the Review Manager (RevMan) computer program Version 5.4.1 (The Cochrane Collaboration, 2020) with a random-effects model. The primary efficacy outcomes were changes in body weight, BMI, and BMI Z-score, while the secondary outcomes were the incidence of gastrointestinal adverse events, treatment discontinuation rate due to adverse events, and incidence of serious adverse events. The mean difference, odds ratio, and 95% confidence interval (CI) were used to present the meta-analysis results. Publication bias was visualized using a funnel plot. The quality of the studies was analyzed using Cochrane's Risk of Bias tool (RoB2). RESULTS: A total of seven RCTs with 576 adolescent participants were included in the analysis. GLP-1 RAs significantly achieved greater weight loss than placebo, with a mean difference of -4.98 kg (-8.49, -1.46), I² = 99%, p = 0.006. Subgroup analysis showed that semaglutide had the most pronounced anti-obesity effect (mean difference of -17.70 kg (-18.89, -16.51), p < 0.00001), compared to liraglutide (mean difference of -2.26 kg (-5.17, 0.65), I² = 99%, p = 0.13) and exenatide (mean difference of -3.17 kg (-4.45, -1.90), I² = 0%, p < 0.0001). Similar results were obtained for other efficacy parameters such as BMI and BMI z-score. However, GLP-1 RA was associated with more gastrointestinal adverse events (such as nausea and vomiting) than placebo (3.06 (2.12, 4.42), I² = 0%, p < 0.00001), with incidence comparable among all GLP-1 RAs in the subgroup analysis. The overall risk of bias among included studies was either of 'some concern' or 'high risk.' CONCLUSIONS: Our meta-analysis demonstrated that GLP-1 RAs had a superior anti-obesity effect compared to placebo or lifestyle modification in obese or overweight non-diabetic adolescents, particularly semaglutide, which had a more pronounced anti-obesity effect than liraglutide and exenatide, with tolerable gastrointestinal adverse effects.
RESUMEN
Background Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are gaining popularity in the management of diabetes mellitus and obesity. It has been suggested that this class of medications causes delayed gastric emptying which raised concerns about the potential for aspiration of gastric contents in patients undergoing sedation. This led to a statement by the American Society of Anesthesiologists about their preoperative use. Nevertheless, there is minimal evidence regarding the effects of GLP-1RAs on the risk of aspiration post-esophagogastroduodenoscopy (EGD). In this study, we sought to evaluate the incidence of aspiration and pneumonia in patients receiving GLP-1RAs who underwent EGD. Methodology We performed a retrospective cohort study in TriNetX, a global federated research network of electronic health records. The primary outcome was the development of aspiration post-EGD. Secondary outcomes were the development of aspiration pneumonia and requiring antibiotics post-EGD. One-to-one propensity score matching was performed for age, sex, diabetes mellitus, obesity, and other comorbidities between the cohorts. Results Our analysis showed a small but significant risk of aspiration pneumonitis in patients on GLP-1RAs undergoing elective EGD compared to non-GLP-1RA-receiving patients. However, there was no increased risk of the composite outcome of respiratory failure or intensive care unit (ICU) admission; however, this did not reach statistical significance. Conclusions GLP-1RA use was associated with an increased risk of aspiration in patients undergoing elective upper endoscopy. However, this did not translate to an increased risk of respiratory failure or ICU admission. Our findings highlight the importance of following an individualized approach to preoperative management that takes into consideration GLP-1RA indications and other aspiration risk factors, including advanced age, impaired gag reflex, and gastrointestinal symptoms such as nausea and abdominal distention.
RESUMEN
Purpose Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are an increasingly prevalent class of drugs for managing overweight/obesity and type 2 diabetes mellitus. Postmarket surveillance is essential for characterizing their risk profiles in real-world patient populations as clinical use increases. This study investigated the association of GLP-1RAs with mortality and serious adverse events (AEs) reported to the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). Methods A disproportionality analysis was conducted utilizing FAERS data from Q2 2005 to Q1 2024 to identify AEs listing an approved GLP-1RA as the primary suspect drug. The reporting odds ratio (ROR) was calculated for mortality and serious AEs associated with each GLP-1RA compared to the combined group of all other GLP-1RAs. A signal of disproportionate reporting indicating a potential safety concern was defined as a lower bound of the 95% CI for the ROR exceeding 1.0. Results The analysis identified 287,201 AEs associated with GLP-1RAs during the study period. Disproportionality analyses revealed statistically significant elevated signals for mortality with the earliest approved GLP-1RAs: Byetta (ROR = 2.20, 95% CI: 2.06-2.34) and Victoza (ROR = 2.12, 95% CI: 1.98-2.28). Significant elevated signals for serious AEs were identified with the semaglutide products Ozempic (ROR = 2.77, 95% CI: 2.69-2.85), Rybelsus (ROR = 2.42, 95% CI: 2.26-2.60), and Wegovy (ROR = 1.30, 95% CI: 1.22-1.39); the liraglutide products Victoza (ROR = 2.10, 95% CI: 2.04-2.15) and Saxenda (ROR = 2.21, 95% CI: 2.09-2.33); and Byetta (ROR = 1.11, 95% CI: 1.08-1.14) compared to other GLP-1RAs. The newer GLP-1RAs were associated with a higher proportion of serious AEs reported in younger patients (p < 0.001) and females (p < 0.001). Conclusion This pharmacovigilance study utilizing the FAERS database identified potential safety signals of increased mortality and serious AE reporting associated with certain GLP-1RAs, particularly the earlier approved liraglutide agents Byetta and Victoza. These findings highlight the importance of proactive postmarket surveillance to characterize the real-world safety profiles of individual GLP-1RA drugs.
RESUMEN
PURPOSE OF REVIEW: Body fat distribution plays a significant role in the cardiometabolic consequences of obesity. We review the impact of visceral and hepatic fat and highlight important interventions. RECENT FINDINGS: Several epidemiologic studies have established a clear association between visceral fat and cardiovascular disease. The association between hepatic fat and cardiovascular disease is less clear with discordant results. Novel evidence demonstrates sodium glucose co-transporter-2 (SGLT2) inhibitors facilitate modest weight loss and reductions in ectopic fat depots in patient with type 2 diabetes. Glucagon-like peptide-1 (GLP-1) receptor agonists have been associated with decreased visceral/hepatic fat and reductions in MACE in populations with type 2 diabetes and with overweight/obesity. Clear associations between visceral fat and cardiometabolic outcomes have been established, whereas the impact of hepatic fat remains less clear. Lifestyle modification and pharmacologic interventions remain the initial therapies, while surgical intervention is associated with improved long-term outcomes. Emerging therapies have demonstrated a profound impact on body fat distribution and cardiometabolic risk.
RESUMEN
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.
RESUMEN
AIMS/HYPOTHESIS: Regulators worldwide are reviewing safety data on glucagon-like peptide-1 receptor agonists (GLP-1RA), following reports by the Icelandic Medicines Agency in July 2023 of suicidal ideation and self-injury (SIS) in individuals taking liraglutide and semaglutide. We aimed to assess the risk of SIS in new users of GLP-1RA when compared with sodium-glucose cotransporter 2 inhibitors (SGLT-2i) users, prescribed to treat type 2 diabetes in individuals with obesity. METHODS: This is a cohort study combining several population-wide databases and covering a Spanish population of five million inhabitants, including all adults with obesity who initiated treatment with either GLP-1RA or SGLT-2i for type 2 diabetes from 2015 to 2021. To estimate the comparative effect of GLP-1RA on the risk of SIS, we employed a new user, active comparator design and we carried out multivariable Cox regression modelling with inverse probability of treatment weighting (IPTW) based on propensity scores. We performed several stratified and sensitivity analyses. RESULTS: We included 3040 patients initiating treatment with GLP-1RA and 11,627 with SGLT-2i. When compared with patients treated with SGLT-2i, those in the GLP-1RA group were younger (55 vs 60 years old, p<0.001), had more anxiety (49.4% vs 41.5%, p<0.001), sleep disorders (43.2% vs 34.1%, p<0.001) and depression (24.4% vs 19.0%, p<0.001), and were more obese (35.1% of individuals with BMI ≥40 vs 15.1%, p<0.001). After propensity score weighting, standardised mean differences between groups were <0.1 for all covariates, showing adequate balance between groups at baseline after adjustment. In the main per-protocol analyses we found no evidence that GLP-1RA increased the incidence of SIS (HR 1.04; 95% CI 0.35, 3.14). Intention-to-treat analyses resulted in an HR of 1.36 (95% CI 0.51, 3.61). In analyses excluding individuals with no BMI information and using imputation for BMI missing values, respective HRs were 0.89 (95% CI 0.26, 3.14) and 1.29 (95% CI 0.42, 3.92). Stratified analyses showed no differences between subgroups. CONCLUSIONS/INTERPRETATION: Our findings do not support an increased risk of SIS when taking GLP-1RA in individuals with type 2 diabetes and obesity; however, the rarity of SIS events and the wide uncertainty of effect size (although null, effect may be compatible with a risk as high as threefold) calls for a cautious interpretation of our results. Further studies, including final evaluations from regulatory bodies, are called for to discard a causal link between GLP-1RA and suicidality.
RESUMEN
Background: Cardiovascular outcome trials indicate renal benefits of glucagon-like peptide-1 receptor agonists (GLP-1RAs); however, real-world efficacy and safety studies in Diabetic kidney disease (DKD) are scarce. Methods: This retrospective, single-arm real-world trial involved adults with DKD treated with GLP-1RA for at least 6 months. The primary endpoint was hemoglobin A1c (HbA1c) levels after 6 months. Results: This study included a total of 364 patients with DKD, 153 (42.0%) of whom were female. The median disease duration was 8.0 years, and the mean values of age, HbA1c level, body mass index, and the urinary albumin-to-creatinine ratio (UACR) were 52.1 years, 8.6%, 27.8 kg/m2, and 88.0 mg/g, respectively. Additionally, 73.6% and 26.4% of patients had mild and moderate DKD, respectively. Following 6 months of GLP-1RA treatment, the mean HbA1c level and UACR declined by 1.77% and 40.3%, respectively (both p < 0.001). Compared to their baseline values, patients exhibited significant improvements in 24-h urinary protein, estimated glomerular filtration rate (eGFR), fasting blood glucose, body weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (all p < 0.001). Patients with a disease duration of <10 years had more pronounced changes in the HbA1c level, UACR, and eGFR (all p < 0.001) than those with a disease duration of ≥10 years. Changes in SBP and DBP were more pronounced in patients also taking angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEis/ARBs) than in those not taking ACEis/ARBs, whereas the changes in UACR and eGFR did not significantly differ. Conclusion: Six-month GLP-1RA treatment improves glucose, blood pressure, lipids, and body weight in patients with mild-to-moderate DKD while slowing down kidney disease progression. It independently reduces proteinuria beyond ACEi/ARB impact, with early use yielding faster outcomes, supporting evidence-based practice.
RESUMEN
Background Dyslipidemia is a common complication of type 2 diabetes mellitus (T2DM), which is the leading cause of morbidity and mortality in developed countries, including Saudi Arabia. Injectable glucagon-like peptide-1 receptor agonists (GLP-1RA) are recent therapies found to be effective in treating dyslipidemia in diabetic patients by acting similarly to the body's internal glucagon peptide hormone, regulating blood sugar levels and reducing triglycerides and low-density lipoprotein (LDL) levels. Aim of the study This retrospective cohort study aimed to investigate the effect of GLP-1RA on the lipid profile of dyslipidemia diabetic patients who were not controlled using statins. Methods Data were collected from the medical records of male and female diabetic patients with dyslipidemia (uncontrolled by statins) who were administered to the diabetic center of King Salman Bin Abdulaziz Hospital in Riyadh, Saudi Arabia, and received GLP-1RA (dulaglutide) from June 2023 to August 2023. The primary endpoint was the change in triglycerides and LDL-C levels after three months of using dulaglutide, and the secondary endpoints included the change in body weight, BMI, and HbA1c%. Descriptive analysis was conducted to present numerical and categorical data. The Wilcoxon signed-rank test was used to compare numerical data before and after using dulaglutide. Ethical considerations were taken into account by ensuring anonymous data collection and obtaining IRB approval before data collection. Results The study included 102 patients with a median (interquartile range (IQR)) age of 59 (14) years. Females constituted 55.2% of the population. Obesity (96.1%), hypertension (71.6%), and retinopathy (13.7%) were the most commonly reported comorbidities. The study showed a significant reduction in body weight, BMI, HbA1c, hemoglobin, mean corpuscular volume (MCV), serum LDL-C, and triglyceride concentrations after three months of using dulaglutide (p<0.001). Conclusion Our study results confirm the positive effect of the GLP-1RA (dulaglutide) on the lipid profile of diabetic patients with dyslipidemia uncontrolled by statins.
RESUMEN
Glucagon-like peptide-1 receptor agonist (GLP-1RA) medications have been shown to be effective in achieving optimal glucose control and reducing all-cause death, cardiovascular death, nonfatal myocardial infarction, hospitalization for heart failure, and end-stage kidney disease in individuals with type 1 (T1D) and type 2 diabetes (T2D). However, use of these medications has been associated with increased hypoglycaemia risk in patients treated with concomitant antihyperglycaemic medications. The risk is particularly high in patients with T1D due to their loss of glucagon counter-regulatory response. This article reviews the effect of GLP-1RA formulations on the development of hypoglycaemia in individuals with T1D and T2D treated with insulin therapy, discusses the benefits of continuous glucose monitoring with GLP-1RA treatment, and presents strategies for safely initiating GLP-1RA therapy in these individuals.
RESUMEN
BACKGROUND: Previous studies have suggested that glucagon-like peptide-1 receptor agonists (GLP-1RAs) may have a disease-modifying effect in the development of Parkinson's disease (PD), but population studies yielded inconsistent results. OBJECTIVE: The aim was to compare the risk of PD associated with GLP-1RAs compared to dipeptidyl peptidase 4 inhibitors (DPP4i) among older adults with type 2 diabetes (T2D). METHODS: Using U.S. Medicare administrative data from 2016 to 2020, we conducted a population-based cohort study comparing the new use of GLP-1RA with the new use of DPP4i among adults aged ≥66 years with T2D. The primary endpoint was a new diagnosis of PD. A stabilized inverse probability of treatment weighting (sIPTW)-adjusted Cox proportional hazards regression model was employed to estimate the hazard ratio (HR) and 95% confidence intervals (CI) for PD between GLP-1RA and DPP4i users. RESULTS: This study included 89,074 Medicare beneficiaries who initiated either GLP-1RA (n = 30,091) or DPP4i (n = 58,983). The crude incidence rate of PD was lower among GLP-1RA users than DPP4i users (2.85 vs. 3.92 patients per 1000 person-years). An sIPTW-adjusted Cox model showed that GLP-1RA users were associated with a 23% lower risk of PD than DPP4i users (HR, 0.77; 95% CI, 0.63-0.95). Our findings were largely consistent across different subgroup analyses such as sex, race, and molecular structure of GLP-1RA. CONCLUSION: Among Medicare beneficiaries with T2D, the new use of GLP-1RAs was significantly associated with a decreased risk of PD compared to the new use of DPP4i. © 2024 International Parkinson and Movement Disorder Society.
RESUMEN
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.
RESUMEN
INTRODUCTION: Over half of Americans and up to 78% of US Veteran population meet criteria for obesity. Perioperatively placed intragastric balloon (IGB) can accelerate weight loss goals for safe surgical candidacy, however weight regain is common after removal. Glucagon-like peptide-1-receptor agonists (GLP1RA) may provide a more sustainable weight loss solution after surgery. We hypothesize that weight regain will be less at 1 year after initiation of GLP1RA than IGB placement in Veterans. METHODS: Retrospective review of prospective databases of perioperatively placed intragastric balloon cohort from 1/2019-1/2023 compared to patients who received initiatory GLP1RA from 6/2021-8/2022 at a VA Medical Center(VAMC). All patients were enrolled in the VAMC MOVE! multidisciplinary weight management program for a minimum of 12 weeks. Outcomes measured were patients' weights at 0, 3, 6, and 12 months and weight change for these intervals. Exclusion criteria included history of bariatric surgery and incomplete weight loss data. RESULTS: Two-hundred-twenty-three patients met inclusion criteria; 110 (49%) patients excluded. Mean age was 54 ± 11 years, the majority (78, 69%) were male, and the mean initial BMI was 37 ± 5.9 kg/m2. Seventeen (15%) patients underwent IGB placement and 96 (85%) patients received semaglutide. Weight (kg) change was measured at intervals: 0-3 months:- 11.8(- 17,- 9.5) IGB vs. - 5.1(- 7.4,- 2.3) semaglutide, p < 0.0001; 0-6 months:- 12.7(- 18.4,- 9.9) vs. - 9.4(- 12.6,- 6.1), p = 0.03; 3-6 months:- 0.5(- 2.3,2.3) vs. - 4.3(- 6.8,- 1.6), p < 0.0001; 6-12 months:3(0,7.3) vs. - 1.9(- 4.7,1), p = 0.0006. CONCLUSION: Weight loss occurs more rapidly in the first 6 months after intragastric balloon placement compared to semaglutide (- 12.7 vs. - 9.4 kg, p = 0.03). Despite ongoing attendance in a comprehensive weight loss program, weight regain is common after IGB removal by an average of 3 kg (23.6%) at 1 year. In contrast, patients on GLP1RA (semaglutide) continue to lose weight during this period. Further studies are needed to determine if optimal long-term outcomes may result from combination therapy with intragastric balloon and semaglutide.
RESUMEN
BACKGROUND: We evaluated the prevalence of "heart stress" (HS) based on NT-proBNP cut-points proposed by the 2023 Consensus of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in asymptomatic patients with T2DM and hypertension or high-normal blood pressure (BP) eligible for SGLT2 inhibitors (SGLT2i) and/or GLP-1 receptor agonists (GLP1-RA), drugs with proven benefits on reducing the incidence of HF, hospitalizations, cardiovascular events and mortality. METHODS: A cross-sectional multicentric study was conducted on 192 consecutive outpatients, aged ≥ 55 years, with hypertension or high-normal BP, referred to three diabetology units. NT-proBNP was collected before starting new anti-diabetic therapy. Patients with known HF were excluded, and participants were classified based on the age-adjusted NT-proBNP cut-points. RESULTS: Mean age: 70.3 ± 7.8 years (67.5% males). Patients with obesity (BMI ≥ 30 Kg/m2): 63.8%. Median NT-proBNP: 96.0 (38.8-213.0) pg/mL. Prevalence of chronic kidney disease (CKD, eGFR < 60 mL/min/1.73m2): 32.1%. Mean arterial BP: 138.5/77.0 ± 15.8/9.9 mmHg. The NT-proBNP values, according to the proposed age-adjusted cut-points, classified 28.6% of patients as "HS likely" (organize elective echocardiography and specialist evaluation), 43.2% as "HS not likely" (a grey area, repeat NT-proBNP at six months) and 28.2% as "very unlikely HS" (repeat NT-proBNP at one year). The presence of CKD and the number of anti-hypertensive drugs, but not glycemic parameters, were independently associated with HS. CONCLUSIONS: According to NT-proBNP, over a quarter of T2DM patients with hypertension/high-normal BP, among those eligible for SGLT2i and/or GLP1-RA, were already at risk of cardiac damage, even subclinical. Most would receive an indication to echocardiogram and be referred to a specialist, allowing the early implementation of effective strategies to prevent or delay the progression to advanced stages of cardiac disease and overt HF.

Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are two incretins that bind to their respective receptors and activate the downstream signaling in various tissues and organs. Both GIP and GLP-1 play roles in regulating food intake by stimulating neurons in the brain's satiety center. They also stimulate insulin secretion in pancreatic ß-cells, but their effects on glucagon production in pancreatic α-cells differ, with GIP having a glucagonotropic effect during hypoglycemia and GLP-1 exhibiting glucagonostatic effect during hyperglycemia. Additionally, GIP directly stimulates lipogenesis, while GLP-1 indirectly promotes lipolysis, collectively maintaining healthy adipocytes, reducing ectopic fat distribution, and increasing the production and secretion of adiponectin from adipocytes. Together, these two incretins contribute to metabolic homeostasis, preventing both hyperglycemia and hypoglycemia, mitigating dyslipidemia, and reducing the risk of cardiovascular diseases in individuals with type 2 diabetes and obesity. Several GLP-1 and dual GIP/GLP-1 receptor agonists have been developed to harness these pharmacological effects in the treatment of type 2 diabetes, with some demonstrating robust effectiveness in weight management and prevention of cardiovascular diseases. Elucidating the underlying cellular and molecular mechanisms could potentially usher in the development of new generations of incretin mimetics with enhanced efficacy and fewer adverse effects. The treatment guidelines are evolving based on clinical trial outcomes, shaping the management of metabolic and cardiovascular diseases.

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.
