Clinical Recommendations to Manage Gastrointestinal Adverse Events in Patients Treated with Glp-1 Receptor Agonists: A Multidisciplinary Expert Consensus

On the Frontlines of Cardiovascular-Kidney-Metabolic Syndrome: A Review of GLP-1 and Dual GLP-1/GIP Receptor Agonists in Cardiovascular and Kidney Health

PURPOSE

The purpose of this review is to highlight the role of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonists (GLP-1/GIP RAs) in managing cardiovascular-kidney-metabolic (CKM) syndrome, focusing on their cardiovascular (CV) and kidney-protective effects beyond glycemic control.

SUMMARY

In multiple randomized controlled trials, GLP-1 RAs were demonstrated to confer significant benefits in reducing CV events and preserving kidney function in patients with preexisting atherosclerotic cardiovascular disease (ASCVD) and those at high CV risk. Current guidelines, including those from the Kidney Disease: Improving Global Outcomes (KDIGO) initiative and the American Diabetes Association (ADA), underscore the therapeutic potential of these agents for managing chronic kidney disease (CKD), type 2 diabetes mellitus (T2DM), and metabolic syndrome. Additionally, emerging data suggests their utility beyond T2DM. This review summarizes the evidence supporting these guidelines, along with newer findings not yet fully integrated into clinical practice. It also examines the role of pharmacists and multidisciplinary teams, safety considerations, and practical strategies for managing common adverse effects.

CONCLUSION

The integration of GLP-1 RAs and dual GLP-1/GIP RAs into clinical practice offers substantial benefits for patients, both with and without diabetes. Pharmacists play a pivotal role in recommending evidence-based treatments for those at high CV and kidney risk, educating patients, addressing social determinants of health, and bridging gaps across multidisciplinary care teams.

Discontinuing glucagon-like peptide-1 receptor agonists and body habitus: A systematic review and meta-analysis

Research on Glucagon-like peptide 1 receptor agonist (GLP-1RA) has mainly focused on the efficacy of weight loss and not the long-term efficacy of weight loss maintenance. This systematic review and meta-analysis aims to evaluate the sustainability of weight loss of patients taking GLP-1RAs following the discontinuation of the drug. EBSCOhost was used to simultaneously search Academic Search Premier, CINHAL Ultimate, Cochrane Central Register of Controlled Trials, MEDLINE with full text, Cochrane Database of Systematic Reviews, and separate PubMed search was systematically investigated using a predetermined search strategy from inception to February 1st, 2024. The authors extracted data regarding body weight change from baseline on treatment and off treatment, change in waist circumference from baseline on and off treatment, and change in BMI from baseline on and off treatment. Meta-analysis was conducted using RevMan (version 5.4) to calculate pooled mean differences using a Der Simonian-Laird Random Effects model. ResultsThe initial search yielded 497 relevant articles and, after screening, retained 8 randomized controlled trials comprised of 2372 participants, all with a BMI ≥ 27 kg/m2. After discontinuing GLP-1RA therapy, weight regain was proportional to the original weight loss. Participants who took liraglutide regained 2.20 kg (95% CI 1.69 to 2.70, P < 0.00001), and participants taking semaglutide/tirzepatide regained 9.69 kg (95% CI 5.78 to 13.60, P < 0.00001). This systematic review and meta-analysis show that significant weight is regained after discontinuing GLP-1RA treatment, which should be discussed when stopping therapy. PRACTITIONER POINTS: Question: Does discontinuation of Glucagon-like peptide 1 receptor agonist (GLP-1RA) treatment lead to significant weight gain? Findings: In this systematic review and meta-analysis, discontinuing GLP-1RA treatment led to a pooled overall mean weight regain of 2.20 kg in participants taking liraglutide and 9.69 kg in those patients prescribed semaglutide/tirzepatide. The proportion of weight regained was proportional to the amount originally lost. Meaning: Discontinuation of GLP-1RA treatment leads to weight regain, regardless of lifestyle interventions, and should therefore be considered a chronic therapy to prevent weight regain and associated undesirable outcomes related to obesity.

Real-world evidence on the utilization, clinical and comparative effectiveness, and adverse effects of newer GLP-1RA-based weight-loss therapies

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have emerged as key agents for weight management, based on their marked efficacy as observed in randomized controlled trials. While still limited, real-world studies on GLP-1RA use in populations with obesity are increasingly available. This narrative review discusses contemporary real-world evidence demonstrating the utilization, clinical and comparative effectiveness, and adverse effects of the currently approved GLP-1RA-based weight-loss therapies, that is, liraglutide, semaglutide and tirzepatide. The observed weight reduction in clinical practice overall tends to be lower than in randomized controlled trials; however, outcomes approach those seen in trials when focusing on highly adherent patients. Real-world studies demonstrate high discontinuation rates of GLP-1RAs (20%-50%) within the first year, and the use of much lower doses than those evaluated in clinical trials. Evidence from observational studies within type 2 diabetes or obesity populations suggests frequent gastrointestinal disturbances in GLP-1RA users, as also observed in trials, but no clear increase in risks of severe events like pancreatitis or pancreatic cancer, thyroid disorders, or depression and self-harm. Further evidence is needed to understand possible real-world associations of GLP-1RAs with eye disease and other rare outcomes. We provide 10 areas of particular importance for further research on GLP-1RA within the real-world space, including improved understanding of the exact drivers of early discontinuation and suboptimal dosing, studies of the effects of stopping GLP-1RA treatment, and investigations of clinical and cost-effectiveness for hard clinical outcomes in real-world settings, including not only cardio-reno-metabolic outcomes but also obesity-induced diseases like neuropsychiatric disease, cancer, musculoskeletal disease, and infections. PLAIN LANGUAGE SUMMARY: Recent advancements in weight-loss medications have sparked a lot of interest. The so-called GLP-1 receptor agonist medications (GLP-1RAs) have gained a lot of attention, because they have shown to be very effective, leading to significant weight loss in patients participating in clinical trials. GLP-1RAs, like liraglutide, semaglutide, and tirzepatide, help manage weight by mimicking hormones that control blood sugar and appetite. However, how these medications perform in real life can be different from the controlled settings of clinical trials, in which patients are carefully selected and their treatment plans closely followed. This literature review looks at how these medications are used and their effectiveness and safety in real-world settings. In real-life practice, GLP-1RAs are often less effective than in clinical trial conditions. This is usually because patients don't follow their medication plans as strictly as in trials. Real-world data shows that many patients use lower doses and do not stick to their treatment as strictly as participants in a controlled trial might, leading to less weight loss. However, those who do follow their plans closely can achieve results similar to those in trials. A major issue with GLP-1RAs is that many patients stop using them within the first year due to side effects or high costs of the medications, especially if not covered by insurance. Common side effects include nausea and digestive problems, which are the main reasons patients stop taking these treatments. These side effects are often manageable and decrease over time, and this reviews found no strong real-world evidence that GLP-1RAs cause severe side effects in many users. Despite these challenges, when GLP-1RAs are used effectively and consistently, they show substantial benefits in weight loss, most so the newest medications semaglutide and tirzepatide. These medications are also likely to help manage and prevent weight-related health conditions like type 2 diabetes and cardiovascular disease, but evidence for these beneficial outcomes is still scarce in real-world settings. The review emphasizes the need for more research to understand why many patients stop using these medications and how to improve dosing. It also calls for studies on the long-term effects of these therapies on various health outcomes, including mental health, cardiometabolic health, cancer, and rare conditions like eye diseases. Overall, while GLP-1RAs are a valuable tool for weight management, their real-world use requires careful consideration of individual patient factors, such as the ability to stick to treatment plans, manage side effects, and afford the medications. Further research will help make these treatments more effective for a wider range of people that need them.

The safety, tolerability, pharmacokinetics and pharmacodynamics of an optimized dual GLP-1/GIP receptor agonist (BGM0504) in healthy volunteers: A dose-escalation Phase I study

OBJECTIVE

Previous experiments have demonstrated that BGM0504, a GLP-1R/GIPR dual agonist drug by molecular dynamics-guided optimization, had enhanced agonistic activity compared to tirzepatide. This study aims to investigate its safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) in Chinese healthy volunteers.

METHODS

A randomized, double-blind, placebo-controlled and dose-escalation Phase I study was conducted as follows: a single dose (2.5 mg) and once-weekly administration for 2 weeks to reach target doses (5, 10 and 15 mg) by titration.

RESULTS

A total of 40 volunteers received at least one dose of BGM0504 or placebo. The PK profile of BGM0504 was investigated over a wide dose range and supported once-weekly administration. It was observed that Cmax and AUC of BGM0504 were linearly proportional to the dose from 2.5-15 mg. The change in body weight (%) from baseline in BGM0504 groups was greater than that in the placebo group, with -3.24%, -6.26%, -7.09% and - 8.30% in 2.5, 5, 10 and 15 mg groups, respectively, indicating a certain dose correlation. Meanwhile, the potential roles of BGM0504 in glycaemic control were also observed. The most frequent adverse events reported were gastrointestinal (vomiting, nausea, decreased appetite, diarrhoea and abdominal distension).

CONCLUSION

BGM0504 was generally safe and well tolerated with favourable PK profile and potential role in weight loss was also confirmed. These findings support subsequent development of BGM0504 for type 2 diabetes mellitus (T2DM) and obesity.

How 'miracle' weight-loss semaglutide promises to change medicine but can we afford the expense?

Obesity is a complex and growing global concern, affecting one in eight individuals and compromising health, quality of life and life expectancy. It carries significant metabolic, cardiovascular, oncological, hepatorenal, skeletal and psychiatric risks, imposing substantial costs on health-care systems. Traditional treatments have often been ineffective or have led to relapse after lifestyle changes. Whereas bariatric surgery is effective, it also involves risks such as mortality and hospitalisation. Semaglutide, licensed in 2018, is a synthetic analogue of glucagon-like peptide 1 which regulates glucose metabolism and gastrointestinal (GI) motility. Studies show that semaglutide, administered either weekly and subcutaneously, or daily orally, induces an average weight loss of -11.62 kg compared to placebo and reduces waist circumference by up to -9.4 cm. It also improves blood pressure, fasting glucose levels, C-reactive protein levels and lipid profiles. The most common adverse events are mild-to-moderate GI complaints occurring more frequently with daily administration than weekly doses; hypoglycaemia is more common without lifestyle intervention. Weight regain often follows semaglutide withdrawal. Furthermore, semaglutide offers cardiovascular benefits for patients with established atherosclerotic cardiovascular disease (CVD), lowers the risk of kidney outcomes and cardiovascular-related death, resolves nonalcoholic steatohepatitis in many cases, and positively impacts mental health and quality of life. In conclusion, semaglutide therapy could significantly benefit many adults regarding CVD and mortality if made widely accessible. Ethical and financial considerations must be addressed for personalised obesity treatment approaches.

Exploring glucagon-like peptide-1 receptor agonists as potential disease-modifying agents in autoimmune diseases

BACKGROUND

Glucagon-like peptide-1 receptor (GLP-1R) agonists are emerging with therapeutic agents for the treatment of two of the most prevalent metabolic disorders: diabetes and obesity. However, the causal relationship between GLP-1R agonists and autoimmune diseases is still unclear.

METHODS

The available cis-eQTLs for drug target genes (GLP-1Rs) were used as proxies for exposure to GLP-1R agonists. Obesity and type 2 diabetes mellitus (T2DM) were used as positive controls to ensure the reliability of the genetic instrument. Mendelian randomization (MR) was performed to reveal the causal association of genetic proxy GLP-1R agonists with 18 autoimmune diseases from the IEU OpenGwas database and FinnGen database. Finally, the results of the two databases were analyzed via meta-analysis.

RESULTS

A total of 22 significant cis-eQTL single-nucleotide polymorphisms were included as genetic instruments. Positive control analysis revealed that GLP-1R agonists were significantly associated with obesity (OR = 0.826, p = 0.021) and T2DM (OR = 0.886, p < 0.001), which is consistent with the meta-analysis. MR analysis revealed that increased expression of the GLP-1R gene has a significant protective effect on type 1 diabetes mellitus (T1DM), hypothyroidism, primary biliary cholangitis (PBC) and rheumatoid arthritis (RA). However, the MR analysis suggested that increased expression of GLP-1R agonists may increase the risk of Graves' disease (GD), ulcerative colitis (UC) and psoriasis. Our findings were consistent with those of the meta-analysis.

CONCLUSIONS

This study provides new insights into potential adjuvant treatments for autoimmune diseases from the perspective of genetic variation and provides evidence for the safety of GLP-1R agonists.

GLP-1 Receptor Agonists in Pediatric and Adolescent Obesity

Obesity remains highly prevalent among children in the United States and is associated with an ever-increasing burden of obesity-related diseases. Effective pediatric obesity prevention and treatment will require both societal interventions and health care system innovation. One recent advancement is the approval of glucagon-like peptide-1 receptor agonists (GLP-1RAs) for use in adolescents. GLP-1RAs are notable for their effectiveness in weight management and in their ability to ameliorate obesity-related diseases. GLP-1RAs can be an important part of a comprehensive treatment plan for pediatric patients seeking obesity care, and we will review the pediatric clinician's considerations for their effective use. We discuss the history of obesity pharmacology and development of GLP-1RAs. We review the indications for use and common adverse reactions. We highlight the importance of mental health care for obesity treatment, with a focus on disordered eating behaviors and their intersection with obesity and pharmacologic treatment of obesity. Nutrition remains an important issue for obesity prevention and management, and we highlight nutritional concerns during GLP-1RA therapy. Finally, we discuss health inequities in obesity, the dangers of perpetuating these inequities if GLP-1RA access remains biased, and the opportunities for improvement.

Oral Semaglutide and Cardiovascular Outcomes in High-Risk Type 2 Diabetes

BACKGROUND

The cardiovascular safety of oral semaglutide, a glucagon-like peptide 1 receptor agonist, has been established in persons with type 2 diabetes and high cardiovascular risk. An assessment of the cardiovascular efficacy of oral semaglutide in persons with type 2 diabetes and atherosclerotic cardiovascular disease, chronic kidney disease, or both is needed.

METHODS

In this double-blind, placebo-controlled, event-driven, superiority trial, we randomly assigned participants who were 50 years of age or older, had type 2 diabetes with a glycated hemoglobin level of 6.5 to 10.0%, and had known atherosclerotic cardiovascular disease, chronic kidney disease, or both to receive either once-daily oral semaglutide (maximal dose, 14 mg) or placebo, in addition to standard care. The primary outcome was major adverse cardiovascular events (a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke), assessed in a time-to-first-event analysis. The confirmatory secondary outcomes included major kidney disease events (a five-point composite outcome).

RESULTS

Among the 9650 participants who had undergone randomization, the mean (±SD) follow-up was 47.5±10.9 months, and the median follow-up was 49.5 months. A primary-outcome event occurred in 579 of the 4825 participants (12.0%; incidence, 3.1 events per 100 person-years) in the oral semaglutide group, as compared with 668 of the 4825 participants (13.8%; incidence, 3.7 events per 100 person-years) in the placebo group (hazard ratio, 0.86; 95% confidence interval, 0.77 to 0.96; P = 0.006). The results for the confirmatory secondary outcomes did not differ significantly between the two groups. The incidence of serious adverse events was 47.9% in the oral semaglutide group and 50.3% in the placebo group; the incidence of gastrointestinal disorders was 5.0% and 4.4%, respectively.

CONCLUSIONS

Among persons with type 2 diabetes and atherosclerotic cardiovascular disease, chronic kidney disease, or both, the use of oral semaglutide was associated with a significantly lower risk of major adverse cardiovascular events than placebo, without an increase in the incidence of serious adverse events.

Unmasking Gastroparesis in Diabetes During Ramadan: Challenges and Management Strategies

Gastroparesis, characterized by delayed gastric emptying without mechanical obstruction, is a recognized complication of long-standing diabetes. Its pathophysiology involves, amongst other mechanisms, autonomic dysfunction due to vagal nerve damage, impaired smooth muscle contractility, and hormonal dysregulation of intestinal motility. During Ramadan, fasting causes significant dietary changes due to prolonged fasting and the consumption of large meals for Iftar (breaking of fast), which may unmask or worsen gastroparesis symptoms in individuals with diabetes. Symptoms such as early satiety, bloating, nausea, and glycemic fluctuations can further complicate diabetes management during fasting. This paper highlights the relationship between Ramadan fasting and gastroparesis in individuals with diabetes, exploring underlying mechanisms, clinical manifestations, diagnostic approaches, and management strategies. A multidisciplinary approach involving dietary modifications, medication adjustments, lifestyle changes, and individualized medical counseling is essential for safe fasting, alongside the option to avoid fasting in individuals who are deemed too high at risk for fasting. Further research is needed to assess the prevalence of subclinical gastroparesis in fasting individuals with diabetes and to optimize risk stratification and management in these patients.

Weight Reduction with GLP-1 Agonists and Paths for Discontinuation While Maintaining Weight Loss

Worldwide, nearly 40% of adults are overweight and 13% are obese. Health consequences of excess weight include cardiovascular diseases, type 2 diabetes, dyslipidemia, and increased mortality. Treating obesity is challenging and calorie restriction often leads to rebound weight gain. Treatments such as bariatric surgery create hesitancy among patients due to their invasiveness. GLP-1 medications have revolutionized weight loss and can reduce body weight in obese patients by between 15% and 25% on average after about 1 year. Their mode of action is to mimic the endogenous GLP-1, an intestinal hormone that regulates glucose metabolism and satiety. However, GLP-1 drugs carry known risks and, since their use for weight loss is recent, may carry unforeseen risks as well. They carry a boxed warning for people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2. Gastrointestinal adverse events (nausea, vomiting, diarrhea) are fairly common while pancreatitis and intestinal obstruction are rarer. There may be a loss of lean body mass as well as premature facial aging. A significant disadvantage of using these medications is the high rate of weight regain when they are discontinued. Achieving success with pharmacologic treatment and then weaning to avoid future negative effects would be ideal.

Role of Incretin Mimetics in Cardiovascular Outcomes and Other Classical Cardiovascular Risk Factors beyond Obesity and Diabetes Mellitus in Nondiabetic Adults with Obesity: a Meta-analysis of Randomized Controlled Trials

BACKGROUND

Emerging data on cardiovascular outcomes, specifically major adverse cardiovascular events (MACE), are being reported from various trials involving incretin mimetics, such as glucagon-like peptide-1 receptor agonists (GLP-1 RA) and glucose-dependent insulinotropic polypeptide (GIP), especially among patients with obesity and diabetes. Our aim was to evaluate this matter, while also involving various traditional cardiovascular risk factors [e.g., several body weight (BW) parameters, blood pressure (BP), lipid profile].

METHODS

A search of PubMed, Europe PMC, ScienceDirect, Cochrane, and ClinicalTrials.gov up to September 2024 was performed to identify GLP-1 RA and GIP trials in MACE risk reduction as a primary endpoint. Our secondary endpoints included a reduction in BW, waist circumference (WC), body mass index (BMI), BP changes, and lipid modifying effects, while also yielding safety concerns surrounding the use of these pharmaceutical agents. Mean differences (MD) and risk ratios (RR) were summarized using random-effects model.

RESULTS

A total of 11 eligible randomized controlled trials (RCTs) comprising 8 GLP-1 RA trials and 3 dual GLP-1 RA/GIP (tirzepatide) trials were included. Compared with control groups, GLP-1 RA significantly reduced the MACE risk by 32% [RR 0.68 (95% CI 0.53-0.87); P = 0.002; I2 = 73%, P-heterogeneity < 0.001] and 59% for tirzepatide [RR 0.41 (95% CI 0.18-0.92); P = 0.03; I2 = 0%, P-heterogeneity = 0.96]. Incretin mimetics also substantially reduced BW, BP, and improved lipid panel measures. However, there was an increased risk of adverse events, specifically gastrointestinal disorders within the incretin mimetics subset.

CONCLUSIONS

Incretin mimetics have shown promise in reducing MACE risk while also enhancing cardiovascular risk factors, including blood pressure and lipid profile, in adults with obesity without diabetes.

Impact of Preoperative Glucagon-Like Peptide-1 Receptor Agonist on Outcomes Following Major Surgery

BACKGROUND

Glucagon-like peptide-1 receptor agonists (GLP-1RA) are increasingly being used for the management of diabetes mellitus and obesity. We sought to define the impact of preoperative GLP-1RA use on outcomes following major surgical procedures.

METHODS

Patients who underwent a major surgical procedure between 2013 and 2021 were identified using the IBM MarketScan database. Patients who took GLP-1RA within a year before surgery were categorized as "exposed." After propensity score matching (PSM), multivariable regression analysis was used to define the association of GLP-1RA exposure with postoperative complications.

RESULTS

Among 138,980 patients (coronary artery bypass graft: n = 39,516, 28.4%; pneumonectomy: n = 4,881, 3.5%; abdominal aortic aneurysm repair: 4,459, 3.3%; pancreatectomy: n = 15,873, 11.4%; and colectomy: n = 74,251, 53.4%), most individuals were male (n = 80,871, 58.2%) with a median age of 58 (IQR 53-61) years. 2944 (2.2%) individuals had GLP-1RA exposure before surgery. Overall incidence of complications was 36.5% (n = 50,724); complications included sepsis (n = 6,385, 4.6%), surgical site infections (n = 7,431, 5.3%), thromboembolism (n = 3,609, 2.6%), pneumonia (n = 4,783, 3.4%), renal (n = 9,017, 6.5%), or cardiopulmonary failure (n = 26,661, 19.2%). On unmatched analysis, patients on GLP-1RA had a higher risk of complications (no GLP-1RA: 36.3% vs. GLP-1RA: 44.5% p < 0.001); however, after PSM to account for measured confounders, GLP-1RA exposure was not associated with the odds of surgical complications (OR 0.99 95% CI 0.91-1.08; p > 0.05). Among patients using GLP-1RA during the 2 weeks before surgery (n = 522, 17.7%), there was no association of GLP-1RA with risk of complications (nonrecent GLP-1RA: 44.7% vs. recent GLP-1RA: 44.1%; p = 0.992).

CONCLUSIONS

GLP-1RA use was not associated with an increased risk of complications following major surgical procedures.

Mechanisms and treatment of obesity-related hypertension-Part 2: Treatments

Hypertension is a frequent comorbidity of obesity that significantly and independently increases the risk of cardiovascular and renal events. Obesity-related hypertension is a major challenge to the healthcare system because of the rapid increase in obesity prevalence worldwide. However, its treatment is still not specifically addressed by current guidelines. Weight loss (WL) per se reduces blood pressure (BP) and increases patient responsiveness to BP-lowering medications. Thus, a weight-centric approach is essential for the treatment of obesity-related hypertension. Diet and physical activity are key components of lifestyle interventions for obesity-related hypertension, but, in real life, their efficacy is limited by poor long-term patient adherence and frequently require pharmacotherapy implementation to achieve target BP. In this context, first-generation anti-obesity drugs such as orlistat, phentermine/topiramate, and naltrexone/bupropion are poorly effective, whereas second-generation incretin receptor agonists, including the GLP-1 receptor agonists liraglutide and semaglutide, and in particular the dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) co-agonist tirzepatide, substantially contribute to effective WL and BP control in obesity. SGLT2 inhibitors are weak body weight and BP-lowering medications, but clearly synergize the benefits of these medications. Bariatric surgery remains the gold standard treatment for severe "pathological" obesity and related life-threatening complications. Renal denervation is a valuable rescue treatment for drug-resistant hypertension, commonly related to obesity. Integrating a multifaceted weight-based approach with other strategies, such as antihypertensive drugs and renal denervation, could specifically target the main neuro-hormonal and renal pathophysiological mechanisms of obesity-related hypertension, including sympathetic-nervous and renin-angiotensin-aldosterone systems overactivity, salt retention, and volume expansion. This comprehensive strategy can provide a personalized algorithm for managing hypertension in obesity within the context of "precision medicine" principles.

Unveiling the Therapeutic Potential of the Second-Generation Incretin Analogs Semaglutide and Tirzepatide in Type 1 Diabetes and Latent Autoimmune Diabetes in Adults

Type 1 diabetes mellitus (T1D) is a chronic autoimmune disease caused by the immune-mediated destruction of insulin-producing pancreatic beta cells, resulting in the lifelong need for exogenous insulin. Over the last few years, overweight and obesity have recently emerged as growing health issues also afflicting patients with T1D. In this context, the term "double diabetes" has been coined to indicate patients with T1D who have a family history of type 2 diabetes mellitus (T2D) and/or patients with T1D who are affected by insulin resistance and/or overweight/obesity and/or metabolic syndrome. At the same time, the use of second-generation incretin analogs semaglutide and tirzepatide has substantially increased on a global scale over the last few years, given the remarkable clinical benefits of these drugs (in terms of glucose control and weight loss) in patients with T2D and/or overweight/obesity. Although the glucagon-like peptide-1 (GLP-1) receptor agonists and the novel dual GIP (glucose-dependent insulinotropic polypeptide)/GLP-1 receptor agonist tirzepatide are currently not approved for the treatment of T1D, a growing body of evidence over the last few years has shown that these medications may serve as valid add-on treatments to insulin with substantial efficacy in improving glucose control, promoting weight loss, preserving residual beta-cell function and providing other beneficial metabolic effects in patients with T1D, double diabetes and latent autoimmune diabetes in adults (LADA). This manuscript aims to comprehensively review the currently available literature (mostly consisting of real-world studies) regarding the safety and therapeutic use (for different purposes) of semaglutide and tirzepatide in patients with T1D (at different stages of the disease), double diabetes and LADA.

Survodutide for treatment of obesity: rationale and design of two randomized phase 3 clinical trials (SYNCHRONIZE™-1 and -2)

OBJECTIVE

The objective of this study was to describe the rationale and design of two multinational phase 3 clinical trials of survodutide, an investigational glucagon and glucagon-like peptide-1 receptor dual agonist for the treatment of obesity with or without type 2 diabetes (T2D; SYNCHRONIZE-1 and -2).

METHODS

In these ongoing double-blind trials, participants were randomized to once-weekly subcutaneous injections of survodutide or placebo added to lifestyle modification. Survodutide doses are uptitrated to 3.6 or 6.0 mg, and dose flexibility is permitted. Participants (n = 726) in SYNCHRONIZE-1 (NCT06066515) have a baseline BMI ≥ 30 kg/m2 or ≥27 kg/m2 with at least one obesity-related complication but without T2D; participants (n = 755) in SYNCHRONIZE-2 (NCT06066528) have a baseline BMI ≥ 27 kg/m2 and T2D. The primary endpoints are percentage change in body weight and proportion of participants achieving ≥5% body weight reduction from baseline to week 76. Secondary endpoints include change in systolic blood pressure and measures of glycemia. A SYNCHRONIZE-1 substudy is evaluating changes in body composition and liver fat content using magnetic resonance imaging.

CONCLUSIONS

These trials are designed to provide robust evaluation of the efficacy, safety, and tolerability of survodutide for the treatment of obesity in the presence or absence of T2D.

Glucagon-like-peptide-1 agonist therapy in adults with cystic fibrosis

Glucagon-like-peptide-1 (GLP-1) agonists are commonly used to improve glycemic control and promote weight loss in individuals with type 2 diabetes mellitus (T2DM) and/or obesity. However, there is a paucity of evidence regarding GLP-1 agonist use in people with cystic fibrosis (pwCF). We present 11 people with CF (males: 3, females: 7; age range 24-47; BMI range 25.7-43.7) treated with GLP-1 agonists (semaglutide: 9,tirzepatide: 2) for variable duration (1-50 months). All experienced weight loss on GLP- 1 agonist therapy (median change in weight = -7.2 kg; change in BMI [kg/m2] = -0.9 to -8.1). Eight pwCF showed improvement in percent predicted forced expiratory volume in 1 second (ppFEV1) [change = -5 to + 18] and nine pwCF showed improvement in percent predicted forced vital capacity (ppFVC) [change= +1 to + 26]. Of the 7 pwCF with CFRD, all reduced their insulin quantity (mean, 31.5 % decrease in total daily insulin dose), and glucose time in range improved for most (mean, +11 % increase from baseline). Four pwCF stopped using GLP-1 agonists: 2 due to severe nausea/vomiting, 1 due to lack of perceived benefit, and 1 due to change in insurance coverage. This report is the largest published series to date of pwCF treated with GLP-1 agonist therapy. With the addition of GLP-1 agonists, all individuals experienced weight loss and a reduction in daily insulin dose, and most had improvement in pulmonary function. Future multi-center studies are needed to corroborate the efficacy and safety of these agents in the CF population.

Effects of elevated body mass index on the success of total knee and total hip arthroplasty: a comprehensive overview

INTRODUCTION

The average body mass index (BMI) in the United States has tripled over the last five decades despite concerted population-based efforts for weight management. Elevated BMI and, in particular, obesity are risk factors for osteoarthritis. This trend has led to increased demands for total knee (TKA) and total hip arthroplasty (THA), necessitating an in-depth understanding of how elevated BMI impacts TKA and THA.

AREAS COVERED

This paper reviews the literature investigating the effects of elevated BMI, primarily obesity, on TKA and THA, focusing on preoperative, intraoperative, and postoperative considerations. It describes the associated risks, economic implications, and ethical considerations of patients with high BMIs undergoing TKA or THA. To ensure all relevant literature was included, Ovid Medline and Google Scholar databases were searched for the following terms, 'body mass index,' 'obesity,' 'knee,' 'hip,' and 'arthroplasty' for articles published from January 2019 through July 2024.

EXPERT OPINION

Despite the challenges of high BMI in TKA and THA, a deeper understanding of obesity as a chronic illness, coupled with advances in surgical techniques, can improve patient outcomes. A multidisciplinary approach and further research will optimize the care of patients with elevated BMIs undergoing total joint arthroplasty (TJA).

Acute Functional Gastric Outlet Obstruction Associated With Low-Dose Tirzepatide

Obesity has become a significant global challenge, highlighting the need for effective weight loss strategies. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as a promising solution, with tirzepatide gaining significant popularity for its efficacy in promoting weight loss. This case report highlights a 57-year-old male patient with type 2 diabetes on a low dose of tirzepatide who initially presented with severe abdominal pain and vomiting, with symptoms resembling those of acute functional gastric outlet obstruction. Despite initial suspicion of an anatomical obstruction, no abnormalities were found on esophagogastroduodenoscopy. The symptoms resolved following the discontinuation of tirzepatide, suggesting a causative link. This case underscores the importance of physician awareness and patient education regarding potential severe gastrointestinal side effects associated with tirzepatide, even at low doses.

Characterization of Interchanging Incretin Analogs in Clinical Practice: A Descriptive Report

OBJECTIVE

To characterize the tolerability associated with incretin analog interchanges to equipotent or higher strengths based on an interchange process in an adult outpatient setting.

METHODS

This was a retrospective chart review of adult patients receiving care through a participating family medicine or endocrinology clinic between January 1, 2022, and November 30, 2022 at a major academic medical center. An incretin analog equivalency table and protocol for interchange was created in response to ongoing shortages and need for therapy adjustments to different medications within the same class. Patients were included if a recommended incretin analog interchange was initiated and a tolerability assessment was conducted. Patients were excluded if they did not meet inclusion criteria or if they were unreachable for tolerability assessments for interchanged agents.

RESULTS

There were 156 patients included for characterization and response to tolerability of interchange. It was determined that 96% of patients tolerated the incretin analog interchange. A dose escalation occurred in 58% of patients, 41% were transitioned to an equipotent dose, and a dose decrease was considered in 1 patient. Prior authorizations were required 74% of the time for the new therapy. The most common interchanges were dulaglutide 4.5 mg to tirzepatide 7.5 mg, dulaglutide 4.5 mg to tirzepatide 10 mg, and dulaglutide 3 mg to tirzepatide 7.5 mg. These interchanges made up 37.3% of the total population and were observed to have 93% tolerability. Seven patients did not tolerate incretin analog interchange. Five experienced gastrointestinal effects and 2 experienced injection site reactions. The interchange of incretin analog was estimated to reduce time to maximum dose by a median of 3 months. During this study, no patients experienced interruption of therapy defined as missing a dose of incretin analog.

CONCLUSION

This characterization report demonstrates an effective approach to addressing incretin analog interchanges. A high level of tolerability is evident with the defined interchange process. Future studies should continue to confirm effective and safe interchanges of incretin analogs from outcomes and tolerability reports.

Pharmacological management of pediatric metabolic dysfunction-associated steatotic liver disease

Pediatric obesity, characterized by a body mass index (BMI) at or above the 95th percentile for age, affects a substantial number of children and adolescents worldwide. Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease, represents a prominent hepatic manifestation of obesity and metabolic syndrome, emerging as the most prevalent hepatic disorder among pediatric patients and a significant contributor to liver transplantation in adults. The escalating prevalence of pediatric MASLD mirrors the alarming rise in childhood obesity rates over recent decades. While lifestyle modifications focusing on dietary changes and increased physical activity constitute the cornerstone of MASLD management, achieving and maintaining significant weight reduction remains challenging. Moreover, disease progression often persists despite standard-of-care interventions, warranting exploration into alternative therapeutic strategies. Pharmacological interventions, particularly, glucagon-like peptide-1 receptor agonists (GLP-1RA), have shown promise in addressing pediatric obesity and its associated comorbidities, including MASLD. Recent studies have demonstrated the efficacy of GLP-1RA in inducing weight loss and improving liver enzyme levels, suggesting a potential role in halting disease progression, and reducing the risk of major adverse liver outcomes. This review provides a comprehensive overview of the current pharmacotherapy landscape for pediatric MASLD, with a focus on novel agents such as GLP-1RA. Furthermore, the manuscript proposes a practical algorithm to assist in integrating GLP-1RA into the clinical management of pediatric patients with obesity and MASLD. Despite promising results, further research is warranted to elucidate the long-term efficacy and safety of GLP-1RA in pediatric populations.

Dietary Recommendations for the Management of Gastrointestinal Symptoms in Patients Treated with GLP-1 Receptor Agonist

GLP-1 receptor agonist (GLP-1RA) have been developed to address the global burden of obesity and are renowned for their safety and efficacy. These medications influence hunger and satiety, reducing energy intake and promoting weight loss. Despite their benefits, GLP-1RAmay cause a slowed gastric emptying, leading to gastrointestinal symptoms. This study examines how food properties and meal composition affect these symptoms. Dietary recommendations are provided, particularly for evening meals, focusing on how different foods and nutrients can influence the rate of gastric emptying, to improve patient compliance and prevent interruption in weight loss.

Glucagon-like Peptide-1 Receptor Agonists and Diabetic Kidney Disease: From Bench to Bed-Side

Glucagon-like peptide-1 (GLP-1) receptor agonists are currently available for the management of type 2 diabetes mellitus. They have been shown to help with diabetic kidney diseases through multiple mechanisms. In this review, we will shed light on the different mechanisms of action through which GLP-1 receptor agonists may achieve their roles in renal protection in diabetics, both in animal and human studies, as well as review the renal outcomes when using these drugs and their safety profile in diabetic patients.

The relative risk of clinically relevant cholelithiasis among glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes mellitus, real-world study

BACKGROUND AND AIM

The association between biliary disorders with weight reduction enhanced by GLP-1RAs was observed frequently, nevertheless, the relative risk of the clinically relevant cholelithiasis was not specified clearly among different GLP-1RAs.

METHODS

308 patients with type 2 diabetes mellitus (T2D) were recruited and divided into 4 groups; liraglutide, dulaglutide, semaglutide, versus control group; comprised of 69, 76, 71, and 92, respectively. Clinical history, examination, laboratory, and radiology tests were implemented.

RESULTS

Cholelithiasis significantly associates GLP1-RAs (p = 0.033). Overall cholelithiasis was evident in 31.2% of our participants. Symptomatic cholelithiasis prevails in 60.4% of patients with cholelithiasis. Symptomatic complicated cholelithiasis prevailed in 33.3%; distributed in 28.1%, 28.1%, 21.9%, and 21.9% in liraglutide, semaglutide, dulaglutide, and control groups, respectively. Meanwhile, symptomatic uncomplicated cholelithiasis was observed in 27.1%; distributed in 34.6%, 30.8%, 15.4%, and 19.2% in Liraglutide, semaglutide, dulaglutide, and control groups, respectively. Asymptomatic cholelithiasis was noted in 36.8%, 21.1%, 10.5%, and 31.6% of patients with dulaglutide, semaglutide, liraglutide, and control groups, respectively. Specifically, 81.1%, 68%, and 44% of patients with liraglutide, semaglutide, and dulaglutide experienced symptomatic cholelithiasis. The relative risk of cholelithiasis was 1.2, 1.3, and 1.4 in liraglutide, dulaglutide, and semaglutide with number needed to harm of 17.25, 14.69, and 10.96, respectively. The relative risk of symptomatic cholelithiasis was 1.6, 0.9, and 1.4 in liraglutide, dulaglutide, and semaglutide with number needed to harm of 3.14, 16.67, and 5.56, respectively.

CONCLUSION

Liraglutide was associated with the highest risk of clinically relevant cholelithiasis than semaglutide, and dulaglutide in patients with T2D.

Glucagon-like Receptor-1 agonists for obesity: Weight loss outcomes, tolerability, side effects, and risks

Background

This review investigates the side effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) like liraglutide, semaglutide, and tirzepatide, medications known for their efficacy in promoting weight loss among individuals with obesity. The rationale is rooted in understanding the balance between their therapeutic benefits and associated risks.

Methods

This was a comprehensive clinical review, including systematic reviews, meta-analyses, randomized controlled trials (RCTs), and cohort studies. Data were extracted from databases such as PubMed, Scopus, Embase, MEDLINE, and Google Scholar, focusing on the tolerability, severity, and risks of these medications.

Results

GLP-1RAs demonstrated significant weight loss outcomes. In clinical trials, liraglutide showed a placebo-corrected weight loss of around 5 %, semaglutide 12 %, and tirzepatide 18 %. Common side effects were predominantly gastrointestinal, including nausea, diarrhea, constipation, and vomiting. Rare serious adverse events included gallbladder disorders and acute pancreatitis. In, addition, multiple studies identify new risks associated with GLP-1RAs including increased aspiration risk during anesthesia due to delayed gastric emptying and challenges with bowel preparation for colonoscopies.

Conclusion

While GLP-1RAs are effective in managing obesity, their use is associated with gastrointestinal side effects and rare but serious adverse events. The findings underscore the importance of individualized dosing and thorough patient assessment. Continuous research and vigilant monitoring are essential to optimize their safe use. Further studies are needed to refine guidelines, particularly regarding new concerns such as delayed gastric emptying and its implications for anesthesia.

Management of Overweight and Obesity in Patients With Inflammatory Bowel Disease

Increasing evidence has linked obesity to complications of inflammatory bowel disease (IBD); however, data are limited on the efficacy and impact of weight management strategies on the disease course. There are a strikingly limited number of interventional studies on weight management in patients with IBD, and the recent nutrition and IBD guidelines published in the United States do not mention weight management strategies. Overweight and obesity management in patients with IBD should follow a stepwise approach to assessment and treatment, including lifestyle modification, anti-obesity medications such as glucagon-like peptide-1 agonists, endobariatric procedures, and bariatric surgery (if deemed appropriate). This article reviews the management of overweight and obesity in patients with IBD, examines the efficacy of currently available interventions and their impact on the IBD course, and proposes a stepwise approach to the assessment and treatment of overweight or obesity for the IBD provider.

Optimizing nutrition, diet, and lifestyle communication in GLP-1 medication therapy for weight management: A qualitative research study with registered dietitians

Background

This qualitative study used semi-structured interviews to examine registered dietitians' perspectives on diet, nutrition, and lifestyle communication for patients on GLP-1 medications for obesity management.

Methods

Through in-depth interviews with registered dietitians, this research identifies elements that could improve both the efficacy of GLP-1 medication therapies and patient adherence.

Results

indicate that a comprehensive approach, integrating patient communication with proactive management of side effects and ongoing lifestyle counseling, is essential for optimizing treatment outcomes.

Conclusion

Key findings include the importance of using visual and metaphorical aids to improve understanding, the necessity for structured lifestyle programs, and the pivotal role of personalized diet plans. These insights offer valuable directions for enhancing patient care and formulating clinical practices around the use of GLP-1 receptor agonist medications.

Health and Well-Being Coaching Adjuvant to GLP-1 Induced Weight Loss

Glucagon-like peptide agonists (GLP-1) are highly effective anti-obesity medications. However, sustained effectiveness is potentially plagued by lack of adherence to the drug and resumption of pre-weight loss behaviors. Side effects are primarily severe gastrointestinal distress but can occasionally be more serious. Health and well-being coaching (HWC) is an important obesity intervention that can be used alongside GLP-1 prescription. HWC is documented to improve medication adherence and promote healthy behavior change. A coach who understands the complexities of rapid weight loss, specifically with GLP-1, can help the patient persist with the treatment. Moreover, the coach can assist in navigating GLP-1 side effects including undesirable loss of skeletal muscle during the weight loss period. A patient-centric and collaborative relationship seem essential to the HWC process. Specific coaching techniques are suggested for working with patients losing weight. The logical, but yet to be tested, expectation is that HWC as an adjuvant intervention to GLP-1 prescription will improve medication adherence and encourage sustained weight loss and health benefits in patients with obesity.

Liraglutide ameliorates diabetic kidney disease by modulating gut microbiota and L-5-Oxoproline

The gut microbiome-metabolites-kidney axis is a potential target for treating diabetic kidney disease (DKD). Our previous study found that Liraglutide attenuated DKD in rats by decreasing renal tubular ectopic lipid deposition (ELD) and serum metabolites levels, including L-5-Oxoproline (5-OP). However, the response of gut microbiome-metabolites-kidney axis to Liraglutide in DKD rats and the effect of 5-OP on ELD remain unknown. In this study, Sprague-Dawley rats were used as an animal model of DKD. They were subjected to a high fat diet, streptozotocin and uninephrectomy, followed by Liraglutide treatment (0.4 mg/kg d). Additionally, HK-2 cells were incubated with 30 mM glucose and 200 μM palmitate for 24h, and exposed to different concentrations of 5-OP. In DKD rats, Liraglutide dramatically improved the renal tubule structure. It increased the Simpson index (F = 4.487, p = 0.035) and reduced the Actinobacteria-to-Bacteroidetes ratio (F = 6.189, p = 0.014). At the genus level, Liraglutide increased the relative abundance of Clostridium, Oscillospira, Sarcina, SMB53, and 02d06 while decreasing that of Allobaculum. Meanwhile, 13 metabolites were significantly altered after Liraglutide treatment. Multi-omics analysis found that 5-OP levels were positively correlated with Clostridium abundance but negatively correlated with renal injury related indicators. In HK-2 cells, 5-OP significantly reduced the ELD in a dose-dependent manner through inhibiting the expression of SREBP1 and FAS. Overall, the renoprotective effect of Liraglutide in DKD rats is linked to the improvement of the gut microbiota composition and increased serum 5-OP levels, which may reduce ELD in renal tubular cells by lowering lipid synthesis.

Glucagon-like peptide-1 (GLP-1) receptor agonists for weight management: A review for the gynecologic oncologist

The use of glucagon-like peptide-1 receptor agonists (GLP-1RA) has experienced rapid growth amidst the obesity epidemic in the United States. While originally developed for glucose control in Type 2 Diabetes Mellitus, the scope of these agents now extends to encompass weight loss and cardiovascular risk reduction. GLP-1RAs have the potential to induce significant weight loss, in combination with lifestyle modifications, among adults who are overweight or obese. Furthermore, these agents demonstrate efficacy in ameliorating hyperglycemia, enhancing insulin sensitivity, regulating blood pressure, improving cardiometabolic parameters, mitigating kidney dysfunction, and potentially reducing the risk of several obesity-related cancers. Drug-related toxicity is primarily gastrointestinal and active management can prevent drug discontinuation. Obesity is associated both with an increased incidence of malignancy but also with decreased survival. More research is needed to evaluate the potential use of GLP-1RA to modify the endocrine function of adipocytes, regulate the chronic inflammatory state associated with obesity, and prospective applications in oncology. These agents can impact patients with gynecologic malignancies both through their direct mechanism of action as well as potential drug toxicity.

Effect of GLP-1 receptor agonists on weight and cardiovascular outcomes: A review

Diet and lifestyle modifications remain the foundation of obesity treatment, but they have historically proven insufficient for significant, long-term weight loss. As a result, there is a high demand for new pharmacologic treatments to promote weight loss and prevent life-threatening diseases associated with obesity. Researchers are particularly interested in 1 type of drug, glucagon-like peptide 1 receptor agonists (GLP-1 RAs), because of its promising potential in addressing the limitations of non-pharmacologic treatments. In addition to their role in weight loss, these drugs have shown promising early evidence of cardiovascular benefits in obese patients, further enhancing their clinical relevance. Semaglutide and liraglutide, which were initially approved for the treatment of type 2 diabetes, have since been approved by the Food and Drug Administration as weight loss medications due to their effectiveness in promoting significant and sustained weight loss. In this narrative review, we will explore the mechanism of GLP-1 RAs, their effects on weight loss, cardiovascular risk factors and outcomes, common adverse effects, and strategies for managing these effects.

Effects of Chicken Egg Powder, Bovine Colostrum, and Combination Therapy for the Treatment of Gastrointestinal Disorders

Natural-based products are of interest to the pharmaceutical industry as potential sources of novel medicinal compounds. They are also used by consumers/patients as standalone therapies or as an adjunct to Western medicines. Two natural-based products of interest are chicken egg and bovine colostrum (the milk produced in the first few days following calving). Both products are rich in immunoglobulins, antimicrobial peptides, growth factors, and macro- and micro-nutrients. In vitro, in vivo, and a limited number of clinical studies suggest therapeutic benefits of both components given alone and together. Combination therapy is of particular interest, as preclinical studies suggest synergistic effects on growth, repair, and gut protection, including microbiome-induced damage. This article describes the main constituents of egg and bovine colostrum, studies of their use alone and together for a wide range of conditions, highlights areas requiring further research, and describes novel indications such as GLP-1-associated gut symptoms. While well placed in the food supplement arena, additional high-quality clinical trials are required to establish their benefits in clinical practice.

Comparative analysis of semaglutide induced adverse reactions: Insights from FAERS database and social media reviews with a focus on oral vs subcutaneous administration

Background

Compared to alternative weight-loss strategies and medications, semaglutide stands out for its convenience and efficacy, resulting in a significant increase in prescriptions and raising public safety concerns. Furthermore, the safety profiles of its oral and subcutaneous formulations require further examination.

Objective

Our goal is to investigate the potential safety risks associated with semaglutide by analyzing data from the FAERS database and social media. Additionally, we aim to compare the adverse drug reaction (ADR) signals between the oral and subcutaneous administration routes of semaglutide.

Methods

We collected semaglutide-related reports from the FAERS database spanning Q1 2018 to Q2 2023, and patient reviews on WebMD and AskaPatient up to 20 July 2023. Following data extraction and cleansing, we conducted descriptive analyses of demographic characteristics. Subsequently, we calculated adverse drug reaction (ADR) signals using the reporting odds ratio (ROR).

Results

We identified 19,289 and 422 semaglutide-related adverse drug events (ADEs) reported in the FAERS database and online patient reviews, respectively. Gastrointestinal disorders emerged as the most commonly reported System Organ Class (SOC) in both datasets. Predominant Preferred Terms (PTs) included nausea, vomiting, and diarrhea. Serious outcomes constituted 3.07% and 2.25% of all cases for oral and subcutaneous semaglutide, respectively. At the SOC level, gastrointestinal disorders accounted for 30.19% of total ADEs in oral semaglutide, slightly surpassing the 27.76% in subcutaneous semaglutide. The median onset for gastrointestinal PTs was 4 days in both oral (Q1: 1, Q3: 32) and subcutaneous (Q1: 1, Q3: 35) formulations. Noteworthy, new serious adverse event (AE) signals were identified, including hemorrhagic diarrhea (ROR: 3.69), hepatic pain (ROR: 4.20), abnormal hormone levels (ROR: 6.51), and pancreatic failure (ROR: 36.34) in subcutaneous semaglutide, and Dupuytren's contracture (ROR: 46.85) in oral semaglutide.

Conclusion

Our study delineates the safety profile of semaglutide using data from the FAERS database and social media. And identified novel ADR signals specific to oral and subcutaneous forms of semaglutide.

Health Benefits Beyond the Scale: The Role of Diet and Nutrition During Weight Loss Programmes

INTRODUCTION

Obesity management strategies such as caloric restriction, very-low-calorie diets (VLCDs), and meal replacements can lead to moderate short-term weight loss. However, many patients face significant challenges in maintaining these results. Personalized interventions, including behavioral counseling and physical activity, have been shown to improve long-term adherence and success. Current clinical guidelines emphasize the pivotal role of dietitians in enhancing patient outcomes through nutritional therapy. When combined with pharmacotherapy and bariatric surgery, the focus shifts from mere weight loss to broader health improvements.

METHODS

This review explores the evolving role of dietitians in obesity management, advocating for a shift from a weight-centric approach to a more holistic model that prioritizes overall health gains. Key areas of interest include dietetic interventions' impact on metabolic health, cardiovascular function, gut microbiome balance, inflammation, and psychological well-being.

RESULTS

Dietetic interventions have been shown to provide significant health improvements beyond weight loss. These include enhanced metabolic and cardiovascular health, better gut microbiome balance, reduced inflammation, improved sleep quality, mental well-being, and overall quality of life. By focusing on non-scale victories such as improved insulin sensitivity, lipid profiles, and mental health, dietitians play a crucial role in driving long-term success in obesity management. These outcomes highlight the need to shift the focus from short-term weight loss to a more comprehensive view of health gains.

CONCLUSIONS

The role of dietitians in obesity management is expanding to encompass a more comprehensive and individualized approach. Moving beyond a focus on weight reduction, this paradigm promotes long-term, patient-centered strategies that address the multifactorial nature of obesity. By combining dietary changes with regular physical activity and behavioral support, dietitians can contribute to sustained health improvements, treating obesity as a chronic, complex disease.

Exploring the clinical effectiveness of glucagon-like peptide-1 receptor agonists in managing cardiovascular complications: an updated comprehensive review and future directives

The possible cardiovascular advantages of glucagon-like peptide-1 receptor agonists (GLP-1RAs), a class of drugs predominantly used to treat type 2 diabetes (T2D), have garnered increasing attention in recent years. Clinical trials have looked into the possibility that GLP-1RAs have extra cardioprotective benefits in addition to their ability to manage T2D, demonstrating significant major adverse cardiovascular events (MACE) reduction and a favorable safety profile. GLP-1 RAs improve cardiovascular outcomes, especially in those with existing cardiovascular disease. MACE has been steadily declining with this class of drugs, which results in a noticeable rise in cardiovascular outcome trials (CVOTs). GLP-1 RAs have a variety of impacts on the cardiovascular system beyond their function in glycemic control. They offer direct cardioprotection, vasodilation, promotion of salt excretion, reduction of weight, improved lipid profile, and anti-inflammatory qualities through a variety of mechanisms. Thus, this review focuses on GLP-1RAs, its mechanism of action, its clinical effectiveness in CVOTs, the mechanism behind its cardiovascular benefits, its potential role in heart failure, cardiovascular outcomes, its underutilization, and future directives. In conclusion, GLP-1 RAs shows potential in controlling T2D while also lowering cardiovascular risk, but warrants further study into long-term results and real-world data to optimize treatment regimens, ultimately increasing patient outcomes and lowering the burden of cardiovascular disease in T2D populations.

The Use of Semaglutide in Patients With Renal Failure-A Retrospective Cohort Study

OBJECTIVE

Semaglutide, a glucagon-like peptide-1 receptor agonist is approved for weight loss and diabetes treatment, but limited literature exists regarding semaglutide use in patients with advanced chronic kidney disease (CKD). Therefore, this project assessed the safety and efficacy of semaglutide among patients with estimated glomerular filtration rate (eGFR) 15-29 mL/min/1.73 m2 (CKD stage 4), eGFR<15 mL/min/1.73 m2 (CKD stage 5) or on dialysis.

METHODS

This is a retrospective electronic medical record based analysis of consecutive patients with advanced CKD (defined as CKD 4 or greater) who were started on semaglutide (injectable or oral). Data was collected between January 2018 and January 2023. Investigators verified CKD diagnosis and manually extracted data. Data were analyzed using Fisher's exact test, paired t test, linear mixed effects models and Wilcoxon signed rank test.

RESULTS

Seventy-six patients with CKD 4 or greater who initiated semaglutide were included. Most patients had a history of type 2 diabetes mellitus (96.0%), and most were males (53.9%). The mean age was 66.8 y (SD 11.5) with the mean body mass index was 36.2 (SD 7.5). The initial doses were 3 mg orally and 0.25 mg by injection. Maximum prescribed dose was 1 mg (injectable) in 28 (45.2%) patients and 14 mg (orally) in 2 (14.2%) patients. Patients received semaglutide for a median duration of 17.4 (IQR 0.43, 48.8) months. Forty-eight (63.1%) patients reported no adverse effects associated with the therapy. Mean weight decreased from 106.2 (SD 24.2) to 101.3 (SD 27.3) kg (P < .001). Eight patients (16%) with type 2 diabetes mellitus T2DM discontinued insulin after starting semaglutide. Mean hemoglobin A1c (HbA1c) decreased from 8.0% (SD 1.7) to 7.1% (SD 1.3) (P < .001). Adverse effects were the primary reason for semaglutide discontinuation (37.0%), with nausea, vomiting, and abdominal pain being the most common complaints.

CONCLUSIONS

Based on this retrospective study semaglutide appears to be tolerated by most individuals with CKD 4 or greater despite associated gastrointestinal side effects similar to those observed in patients with better kidney function and leads to an improvement of glycemic control and insulin discontinuation in patients with T2DM. Modest weight loss (approximately 4.6% of the total body weight) was observed on the prescribed doses. Larger prospective randomized studies are needed to comprehensively assess the risks and benefits of semaglutide in patients with CKD 4 or greater and obesity.

Gastrointestinal adverse effects of old and new antidiabetics: How do we deal with them in real life?

Diabetes is a public health problem with an estimated worldwide prevalence of 10% and a prevalence of 12% in Mexico. The costs resulting from this chronic-degenerative disease are significant. Treatment for diabetes involves different medication groups, some of which can cause significant gastrointestinal adverse effects, such as dyspepsia, nausea, vomiting, bloating, diarrhea, and constipation. The medications most frequently associated with said adverse effects are metformin, acarbose, and GLP-1 agonists. Gastrointestinal adverse effects negatively impact the quality of life and management of patients with diabetes. The factors of visceral neuropathy, acute dysglycemia, dysbiosis, and intestinal bacterial overgrowth contribute to the gastrointestinal symptoms in patients with diabetes, making it necessary to consider multiple etiologic factors in the presence of gastrointestinal symptoms, and not exclusively attribute them to the use of antidiabetics. Personalized treatment, considering gastrointestinal comorbidity and the type of drug utilized, is essential for mitigating the adverse effects and improving the quality of life in patients with diabetes. The aim of the present narrative review was to describe the gastrointestinal adverse effects of the antidiabetic drugs, their pathophysiologic mechanisms, and the corresponding therapeutic measures.

A review of serious adverse events linked with GLP-1 agonists in type 2 diabetes mellitus and obesity treatment

Glucagon-like peptide-1 (GLP-1) agonists play a crucial role in treating type 2 diabetes mellitus and obesity by providing glycemic control and aiding weight management. Despite their widespread use, concerns about serious adverse events have prompted extensive research. This review aims to describe the current understanding of serious adverse events associated with GLP-1 agonists. A comprehensive search of PubMed, Google Scholar and Embase databases was performed starting from 2010. Studies reporting evidence of an association between GLP-1 agonists and serious adverse events from 22 articles (5 case reports, 5 randomized controlled trials (RCTs), 9 real-world data cohort analyses, 2 meta-analyses and 1 systematic review and meta-analysis) were included and categorized by the type of adverse event. While some studies reported risks, including anaphylaxis, cardiovascular, gastrointestinal, psychiatric and thyroid-related events, others found no significant associations. The evidence remains mixed, necessitating further research to fully understand the safety profile of GLP-1 agonists and inform clinical practice.

A Case Report of Acute Pancreatitis in Food-Induced Anaphylaxis

Food allergy-induced pancreatitis is a rare condition that presents unique diagnostic challenges. While acute pancreatitis (AP) is typically linked to factors such as gallstones, alcohol consumption, metabolic issues, medications, and autoimmune conditions, food allergies are seldom considered a potential cause. Diagnosing food allergy-induced pancreatitis often requires a high index of suspicion and the exclusion of more common causes of pancreatitis. Here we report a 54-year-old female patient who presented at the emergency department (ED) experiencing an anaphylactic reaction to food. After receiving treatment for anaphylaxis, she developed acute abdominal pain 12 hours later. A CT scan of the abdomen indicated AP. The patient was managed with supportive care, including analgesics and intravenous fluids, and did not experience any further complications. Other potential causes and risk factors for AP were ruled out or deemed unlikely. This case highlights the significance of diagnosing AP, particularly food allergy-induced pancreatitis in patients with anaphylaxis. Early detection and early initiation of therapy can subsequently reduce morbidity and mortality.

Recommendations for the management of patients with type 2 diabetes at hospital discharge after an ischaemic cardiovascular event

The document outlines recommendations for the management of patients with type 2 diabetes (T2D) at hospital discharge following an ischaemic cardiovascular event. Diabetes significantly increases the risk of cardiovascular events, and a high proportion of patients in coronary units have this condition. The discharge process is crucial for optimising treatments and reducing the risk of recurrent complications such as reinfarction, stroke, and hospitalisations for heart failure. Strategies include rigorous control of lipid levels, recommending potent statins combined with ezetimibe and, if necessary, other drugs such as inclisiran, evolocumab, alirocumab, or bempedoic acid. Optimal antihypertensive treatment is also suggested as secondary prevention. For patients already on insulin, it is essential to adjust the dosage when adding SGLT-2 inhibitors (SGLT2i) or GLP-1 receptor agonists (GLP-1RA) to avoid hypoglycaemia, with structured glucose monitoring. In cases where HbA1c is not available during hospitalisation, the algorithm guides treatment, highlighting that GLP-1RA and SGLT2i do not cause hypoglycaemia. The combination of these drugs is safe and effective, improving several cardiovascular risk factors. The document emphasises the importance of education on nutrition and healthy habits, as well as the follow-up and adjustment of pharmacological treatments to achieve adequate metabolic control and reduce cardiovascular risks. Nutritional evaluation and control are essential, considering obesity as a critical factor in T2D and its association with the risk of recurrent cardiovascular events.

Achieving equitable access to incretin-based therapies in cardiovascular care

The role of incretin-based therapies, including glucagon-like peptide-1 receptor agonists (GLP1RAs) and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonists, in the management of type 2 diabetes mellitus (T2DM) and obesity has been increasingly recognized, along with significant cardiovascular (CV) benefits. Despite the clinical efficacy of incretin-based therapies, high costs, suboptimal access, limited insurance coverage, and therapeutic inertia present substantial barriers to widespread adoption. Overcoming these obstacles is essential for the equitable initiation, access, and utilization of incretin-based therapies. Clinicians must make targeted efforts to ensure health equity in the use of these and other advanced therapies.

Risk of Suicide, Hair Loss, and Aspiration with GLP1-Receptor Agonists and Other Diabetic Agents: A Real-World Pharmacovigilance Study

PURPOSE

With the increasing popularity of glucagon-like peptide 1 receptor agonists (GLP1-RAs), numerous safety concerns arose pertaining to suicide, hair loss, and aspiration risks. We attempted to validate these concerns.

METHODS

We queried four pharmacovigilance databases to compare GLP1-RAs to sodium-glucose transporter 2 inhibitors (SGLT2is) with respect to these adverse events (AE): the FDA Adverse Event Reporting System (FAERS), the Australian Database of Adverse Event Notifications (DAEN), the European Medicines Agency's (EudraVigilance), and the World Health Organization-Vigibase. OpenVigil 2.1 was utilized to perform a disproportionality analysis for GLP1-RAs, SGLT2is, dipeptidyl peptidase 4 inhibitors (DPP4is), sulfonylureas, metformin, and insulin. The following indices were extracted from the FAERS database from Q4/2003 until Q3/2023: relative reporting ratio (RRR), proportional reporting ratio (PRR), reporting odds ratio (ROR), and chi-squared (χ2). A positive signal was detected if PRR > 2 and χ2 > 4 for any drug-event pair.

RESULTS

No positive signals were observed between GLP1-RAs and either suicide, hair loss, or aspiration risks. Semaglutide [ROR = 0.60 (0.51-0.71)] and liraglutide [ROR = 0.28 (0.23-0.35)] had higher suicidal events than DPP4is and SGLT2is. GLP1-RAs were the most reported class with hair loss [ROR = 0.61 (0.60-0.64)], and semaglutide, liraglutide, and dulaglutide were the three leading medications. GLP1-RAs ranked lower with aspiration events, which were led by sitagliptin and DPP4is as a group.

CONCLUSION

GLP1-RAs exhibit higher reporting of suicide, hair loss, and aspiration events when compared to several other antidiabetic medications despite not meeting the criteria for positive signals yet. This warrants intensive monitoring and reporting.

Comparative efficacy and safety of weekly tirzepatide versus weekly insulin in type 2 diabetes: A network meta-analysis of randomized clinical trials

AIM

To compare the efficacy and safety profiles of recent innovations in type 2 diabetes mellitus (T2DM), which include once-weekly formulations such as tirzepatide, a dual glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptor agonist, and once-weekly insulin options such as icodec and basal insulin Fc.

METHODS

A systematic search of the PubMed, Scopus, Cochrane, and Web of Science databases was conducted. The network meta-analysis protocol was registered at OSF registries (https://osf.io/gd67x). The primary outcome of interest was change in glycated haemoglobin (HbA1c), with change in fasting plasma glucose (FPG), body weight, incidence of hypoglycaemia, and treatment discontinuation as secondary outcomes.

RESULTS

Tirzepatide exhibited superior efficacy in reducing HbA1c levels compared with insulin therapies, with the 15-mg dose showing the most significant reduction (mean difference [MD] -1.27, 95% confidence interval [CI] -1.49; -1.0). In terms of FPG reduction, tirzepatide 15 mg ranked highest (MD -0.70, 95% CI -1.05; -0.34), followed by tirzepatide 10 mg and 5 mg. Additionally, tirzepatide led to substantial weight loss, with the 15-mg dose exhibiting the most pronounced effect (MD -12.13, 95% CI -13.98; -10.27). However, a higher incidence of adverse events (AEs) and treatment discontinuation were associated with tirzepatide, particularly at higher doses.

CONCLUSION

Tirzepatide, particularly at higher doses, demonstrates superior efficacy in lowering HbA1c and reducing hypoglycaemia risk compared with weekly insulin. However, its use is also associated with a higher incidence of AEs and treatment discontinuation.
