Glucagon-like peptide 1 agonists are potentially useful drugs for treating metabolic dysfunction-associated steatotic liver disease

In this editorial,we comment on Yin et al’s recently published Letter to the editor.In particular,we focus on the potential use of glucagon-like peptide 1 receptor agonists(GLP-1RAs)alone,but even more so in combination therapy,as one of the most promising therapies in metabolic dysfunction-associated steatotic liver disease(MASLD),the new definition of an old condition,non-alcoholic fatty liver disease,which aims to better define the spectrum of steatotic pathology.It is well known that GLP-1RAs,having shown outstanding performance in fat loss,weight loss,and improvement of insulin resistance,could play a role in protecting the liver from progressive damage.Several clinical trials have shown that,among GLP-1RAs,semaglutide is a safe,well-studied therapeutic choice for MASLD patients;however,most studies demonstrate that,while semaglutide can reduce steatosis,including steatohepatitis histological signs(in terms of inflammatory cell infiltration and hepatocyte ballooning),it does not improve fibrosis.Combinations of therapies with different but complementary mechanisms of action are considered the best way to improve efficiency and slow disease progression due to the complex pathophysiology of the disease.In particular,GLP-1RAs associated with antifibrotic drug therapy,dual glucose-dependent insulinotropic polypeptide(GIP)/GLP-1RA or GLP-1 and glucagon RAs have promoted greater improvement in hepatic steatosis,liver biochemistry,and non-invasive fibrosis tests than monotherapy.Therefore,although to date there are no definitive indications from international drug agencies,there is the hope that soon the therapeutic lines in the most advanced phase of study will be able to provide a therapy for MASLD,one that will certainly include the use of GLP-1RAs as combination therapy.

Glucagon-like peptide 1 receptor activation:anti-inflammatory effects in the brain

The glucagon-like peptide 1 is a pleiotropic hormone that has potent insulinotropic effects and is key in treating metabolic diseases such as diabetes and obesity.Glucagon-like peptide 1 exerts its effects by activating a membrane receptor identified in many tissues,including diffe rent brain regions.Glucagon-like peptide 1 activates several signaling pathways related to neuroprotection,like the support of cell growth/survival,enhancement promotion of synapse formation,autophagy,and inhibition of the secretion of proinflammatory cytokines,microglial activation,and apoptosis during neural morphogenesis.The glial cells,including astrocytes and microglia,maintain metabolic homeostasis and defe nse against pathogens in the central nervous system.After brain insult,microglia are the first cells to respond,followed by reactive astrocytosis.These activated cells produce proinflammato ry mediators like cytokines or chemokines to react to the insult.Furthermore,under these circumstances,mic roglia can become chro nically inflammatory by losing their homeostatic molecular signature and,consequently,their functions during many diseases.Several processes promote the development of neurological disorders and influence their pathological evolution:like the formation of protein aggregates,the accumulation of abnormally modified cellular constituents,the formation and release by injured neurons or synapses of molecules that can dampen neural function,and,of critical impo rtance,the dysregulation of inflammato ry control mechanisms.The glucagonlike peptide 1 receptor agonist emerges as a critical tool in treating brain-related inflammatory pathologies,restoring brain cell homeostasis under inflammatory conditions,modulating mic roglia activity,and decreasing the inflammato ry response.This review summarizes recent advances linked to the anti-inflammato ry prope rties of glucagon-like peptide 1 receptor activation in the brain related to multiple sclerosis,Alzheimer’s disease,Parkinson’s disease,vascular dementia,or chronic migraine.

Glucagon-like peptide 1 receptor agonist:A potential game changer for cholangiocarcinoma

Glucagon-like peptide-1 receptor(GLP-1R)agonist,a subgroup of incretin-based anti-diabetic therapies,is an emerging medication with benefits in reducing blood glucose and weight and increasing cardiovascular protection.Contrarily,concerns have been raised about GLP-1R agonists increasing the risk of particular cancers.Recently,several epidemiological studies reported contradictory findings of incretin-based therapy on the risk modification for cholangiocarcinoma(CCA).The first cohort study demonstrated that incretin-based therapy was associated with an increased risk of CCA.Later studies,however,showed a null effect of incretinbased therapy on CCA risk for dipeptidyl peptidase-4 inhibitor nor GLP-1R agonist.Mechanistically,glucagon-like peptide 1 receptor is multifunctional,including promoting cell growth.High GLP-1R expressions were associated with progressive phenotypes of CCA cells in vitro.Unexpectedly,the GLP-1R agonist showed anti-tumor effects on CCA cells in vitro and in vivo with unclear mechanisms.Our recent report also showed that GLP-1R agonists suppressed the expression of GLP-1R in CCA cells in vitro and in vivo,leading to the inhibition of CCA tumor growth.This editorial reviews recent evidence,discusses the potential effects of GLP-1R agonists in CCA patients,and proposes underlying mechanisms that would benefit from further basic and clinical investigation.

Impact of glucagon-like peptide receptor agonists on endoscopy and its preoperative management: Guidelines, challenges, and future directions

Glucagon-like peptide receptor agonists(GLP-1RA)are used to treat type 2 diabetes mellitus and,more recently,have garnered attention for their effect-iveness in promoting weight loss.They have been associated with several gastrointestinal adverse effects,including nausea and vomiting.These side effects are presumed to be due to increased residual gastric contents.Given the potential risk of aspiration and based on limited data,the American Society of Anesthesi-ologists updated the guidelines concerning the preoperative management of patients on GLP-1RA in 2023.They included the duration of mandated cessation of GLP-1RA before sedation and usage of“full stomach”precautions if these medications were not appropriately held before the procedure.This has led to additional challenges,such as extended waiting time,higher costs,and increased risk for patients.In this editorial,we review the current societal guidelines,clinical practice,and future directions regarding the usage of GLP-1RA in patients undergoing an endoscopic procedure.

A Retrospective Analysis of Glucagon-Like Peptide 1 Receptor Agonists in Treating Type 2 Diabetes Mellitus Complicated by Nonalcoholic Fatty Liver Disease

Background: The objective of this study was to compare and analyze the variations in clinical indices before and after treatment of type 2 mellitus (T2DM) combined with nonalcoholic fatty liver disease (NAFLD) that were treated with glucagon-like peptide 1 receptor agonists (GLP-1RAs). Methods: The electronic medical record system was utilized to search for a total of 16 patients with type 2 diabetes complicated by NAFLD who were hospitalized at the First Affiliated Hospital of Yangtze University from October 2022 to April 2023 and treated with GLP-1RA for the first time. The clinical indices were compared before and after 12 weeks of treatment with GLP-1RA. Results: The liver-spleen CT ratio (L/S), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) in all patients treated with GLP-1RA after 12 weeks were significantly different (P 0.05). The patients were categorized into two groups based on the types of GLP-1RAs. The changes in L/S, TC, TG, and LDL-C in the long-acting group after treatment were statistically significant (P Conclusions: GLP-1RAs can improve liver function, regulate lipid metabolism, and reduce the severity of fatty liver in patients with T2DM complicated by NAFLD, which demonstrates the importance of clinical applications.

Potential therapeutic targets for nonalcoholic fatty liver disease:Glucagon-like peptide 1

Nonalcoholic fatty liver disease(NAFLD)is the most rapidly growing contributor to liver mortality and morbidity.Hepatocellular injury in nonalcoholic steatohepatitis(NASH)is caused by an increase in metabolic substrates(glucose,fructose,and fatty acids),leading fatty acids to participate in pathways that cause cellular injury and a poor response to injury.The pathogenesis of this disease is largely associated with obesity,type 2 diabetes,and increasing age.To date,there are no Food and Drug Administration-approved treatments for NAFLD/NASH or its associated fibrosis.Since one of the pathogenic drivers of NASH is insulin resistance,therapies approved for the treatment of type 2 diabetes are being evaluated in patients with NASH.Currently,the glucagon-like peptide-1 receptor agonist(GLP-1RA)semaglutide is a safe,well-studied therapeutic for NAFLD/NASH patients.Existing research demonstrates that semaglutide can increase the resolution of NASH but not improve fibrosis.However,improving the fibrosis of NAFLD is the only way to improve the long-term prognosis of NAFLD.Given the complex pathophysiology of NASH,combining therapies with complementary mechanisms may be beneficial.Researchers have conducted trials of semaglutide in combination with antifibrotic drugs.However,the results have not fully met expectations,and it cannot be ruled out that the reason is the short trial time.We should continue to pay increasing attention to GLP-1RAs.

Glucagon-like peptide-2 analogues for Crohn’s disease patients with short bowel syndrome and intestinal failure

Short bowel syndrome(SBS)with intestinal failure(IF)is a rare but severe complication of Crohn’s disease(CD),which is the most frequent benign condition that leads to SBS after repeated surgical resections,even in the era of biologics and small molecules.Glucagon-like peptide-2 analogues have been deeply studied recently for the treatment of SBS-IF.These drugs have a significant intestinotrophic effect and the potential to reduce the chronic dependence of SBSIF patients on parenteral support or nutrition.Teduglutide has been approved for the treatment of SBS-IF,and apraglutide is currently in clinical development.The use of these drugs was examined with a focus on their use in CD patients.

Postprandial glucagon-like peptide 1 secretion is associated with urinary albumin excretion in newly diagnosed type 2 diabetes patients

BACKGROUND Microalbuminuria is an early and informative marker of diabetic nephropathy.Our study found that microalbuminuria developed in patients with newly diagnosed type 2 diabetes mellitus(T2DM).AIM To investigate the association between glucagon-like peptide 1(GLP-1)and microalbuminuria in newly diagnosed T2DM patients.METHODS In total,760 patients were recruited for this cross-sectional study.The GLP-1 levels during a standard meal test and urinary albumin-creatinine ratio(UACR)were determined.RESULTS Patients with microalbuminuria exhibited lower GLP-1 levels at 30 min and 120 min during a standard meal test than patients with normal albuminuria(30 min GLP-1,16.7±13.3 pmol vs 19.9±15.6 pmol,P=0.007;120 min GLP-1,16.0±14.1 pmol vs 18.4±13.8 pmol,P=0.037).The corresponding area under the curve for active GLP-1(AUCGLP-1)was also lower in microalbuminuria patients(2257,1585 to 3506 vs 2896,1763 to 4726,pmol×min,P=0.003).Postprandial GLP-1 levels at 30 min and 120 min and AUCGLP-1 were negatively correlated with the UACR(r=0.159,r=0.132,r=0.206,respectively,P<0.001).The prevalence of microalbuminuria in patients with newly diagnosed T2DM was 21.7%,which decreased with increasing quartiles of AUCGLP-1 levels(27.4%,25.3%,18.9%and 15.8%).After logistic regression analysis adjusted for sex,age,hemoglobin A1c,body mass index,systolic blood pressure,estimated glomerular filtration rate,homeostasis model assessment of insulin resistance,AUC_(glucose)and AUC_(glucagon)patients in quartile 4 of the AUCGLP-1 presented a lower risk of microalbuminuria compared with the patients in quartile 1(odds ratio=0.547,95%confidence interval:0.325-0.920,P=0.01).A consistent association was also found between 30 min GLP-1 or 120 min GLP-1 and microalbuminuria.CONCLUSION Postprandial GLP-1 levels were independently associated with microalbuminuria in newly diagnosed Chinese T2DM patients.

Is Glucagon-like peptide-1, an agent treating diabetes, a new hope for Alzheimer's disease?

Glucagon-like peptide- 1 （GLP- 1） has been endorsed as a promising and attractive agent in the treatment of type 2 diabetes mellitus （T2DM）. Both Alzheimer＇s disease （AD） and T2DM share some common pathophysiologic hallmarks, such as amyloid β （Aβ）, phosphoralation of tau protein, and glycogen synthase kinase-3. GLP-1 possesses neurotropic properties and can reduce amyloid protein levels in the brain. Based on extensive studies during the past decades, the understanding on AD leads us to believe that the primary targets in AD are the Aβ and tau protein. Combine these findings, GLP- 1 is probably a promising agent in the therapy of AD. This review was focused on the biochemistry and physiology of GLP- 1, communities between T2DM and AD, new progresses of GLP - 1 in treating T2MD and improving some pathologic hanmarks of AD.

Effects of glucagon-like peptide-1 receptor agonists on renal function

Glucagon-like peptide-1(GLP-1)receptor agonists result in greater improvements in glycemic control than placebo and promote weight loss with minimal hypoglycemia in patients with type 2 diabetes mellitus.A number of case reports show an association of GLP-1receptor agonists,mainly exenatide,with the development of acute kidney injury.The present review aims to present the available data regarding the effects of GLP-1 receptor agonists on renal function,their use in subjects with chronic renal failure and their possible association with acute kidney injury.Based on the current evidence,exenatide is eliminated by renal mechanisms and should not be given in patients with severe renal impairment or end stage renal disease.Liraglutide is not eliminated by renal or hepatic mechanisms,but it should be used with caution since there are only limited data in patients with renal or hepatic impairment.There is evidence from animal studies that GLP-1 receptor agonists exert protective role in diabetic nephropathy with mechanisms that seem to be independent of their glucose-lowering effect.Additionally,there is evidence that GLP-1 receptor agonists influence water and electrolyte balance.These effects may represent new ways to improve or even prevent diabetic nephropathy.

Glucagon-like peptide 1 in the pathophysiology and pharmacotherapy of clinical obesity

Though the pathophysiology of clinical obesity is un-doubtedly multifaceted, several lines of clinical evidence implicate an important functional role for glucagon-like peptide 1(GLP-1) signalling. Clinical studies assessing GLP-1 responses in normal weight and obese subjects suggest that weight gain may induce functional deficits in GLP-1 signalling that facilitates maintenance of the obesity phenotype. In addition, genetic studies implicate a possible role for altered GLP-1 signalling as a risk factor towards the development of obesity. As reductions in functional GLP-1 signalling seem to play a role in clinical obesity, the pharmacological replenishment seems a promising target for the medical management of obesity in clinical practice. GLP-1 analogue liraglutide at a high dose(3 mg/d) has shown promising results in achieving and maintaining greater weight loss in obese individuals compared to placebo control, and currently licensed antiobesity medications. Generally well tolerated, provided that longer-term data in clinical practice supports the currently available evidence of superior short- and longterm weight loss efficacy, GLP-1 analogues provide promise towards achieving the successful, sustainable medical management of obesity that remains as yet, an unmet clinical need.

Effects of Glucagon-Like Peptide 1 on PDX-1, PAX-6 and NKx2.2 Gene Expressions in Isolated Pancreatic Islets

Objective： To observe the effect of glucagon-like peptide 1 （GLP-1） on the gene expressions of transcription factors （PDX-1, PAX-6 and NKx2.2 ） in freshly isolated rat pancreatic islets and investigate the associated physiological and therapeutic implication of GLP-1. Methods： The isolated rat islets were incubated with 10 nmol/L GLP-1 for 1, 3 and 5 days, respectively. Total cellular RNA was extracted and the expressions of PDX-1, PAX-6 and NKx2.2 gene were detected by semiquantity RT-PCR. Results： Compared with the control group, the PDX-1, PAX-6 and NKx2.2 gene expressions were significantly increased after co-cultured with GLP-1 for 1 day （P 〈 0.05）. The effect was shown in a time-dependent manner. All three gene expressions reached the peak on the 5th day. Conclusion： GLP-1 can improve the function of pancreatic islet by regulating the gene expressions of transcription factors in β cells.

Glucagon-like peptide 1 receptor governs Wnt signaling to promote bone formation

Our previous investigation found that exendin-4 （Ex-4） , a peptide analogue of glucagon-like peptide 1 （GLP-1） , induced bone formation probably by osteoblast activation. Nevertheless, previous investigations did not observe any expression of GLP-1 receptors in osteoblasts, indicating that the direct cell target of GLP-1 and its ana- logues might not be osteoblasts but some other types of cells yet to be identified. To elucidate the underlying mecha- nisms, we performed further investigation in the present study and found that GLP-1 receptor was only identified in bone marrow mesenchymal stem cells （BMSCs）. Furthermore, activation of GLP-1 receptor by Ex-4 promoted the differentiation of B MSCs into osteoblast, which was associated with activation of PKA, nuclear translocation of [5- catenin, activation of PI3K/AKT and inhibition of GSK3β. Ex-4 also inhibited the adipocyte differentiation of BM- SCs, as evidenced by inhibition of PPARγ, lipoprotein lipase expression and lipid production. Blockade of GLP-1 receptor, PKA, PI3K or Wnt pathway, or respective knock-down of GLP-1 receptor and β-catenin in BMSCs inhib- ited the Ex-4 mediated effects. The results indicated that the GLP-1 receptor mediated osteoblastic differentiation and bone formation through stimulation of PKA/β-catenin signaling and inhibition of PKA/PI3IC/AKT/GSK3β？ signaling pathway in BMSCs. The findings reveal a new role of GLP-1 receptor for regulating osteoblastic differentia- tion of B MSCs and may provide a molecular basis for novel anabolic therapeutics against osteoporosis.

Antihypertensive Effect of Sodium-Glucose Cotransporter 2 Inhibitors and Glucagon-like Peptide 1 Receptor Agonists

An increasing body of evidence shows that new antidiabetic drugs—particularly sodium-glucose cotransporter 2(SGLT2)inhibitors and glucagon-like peptide 1(GLP-1)receptor agonists—have a beneficial effect on cardiovascular outcome.The majority of these studies have been performed in patients with heart failure and the results have shown first positive effect on blood pressure(BP)reduction.These effects are more pronounced with SGLT2 inhibitors than with GLP-1 receptor agonists.However,the reasons and mechanisms of action inducing BP reduction are still not sufficiently clear.Proposed mechanisms of SGLT2 inhibitors involve the natriuretic effect,modification of the renin-angiotensin-aldosterone system,and/or the reduction in the sympathetic nervous system.GLP-1 receptor agonists have several mechanisms that are related to glycemic,weight,and BP control.Current data show that SGLT2 inhibitors have a stronger antihypertensive effect than GLP-1 receptor agonists,which is mainly related to their renal effect.Briefly,SGLT2 inhibitors increase the response to diuretics and decrease the meal-related antinatriuretic pressure by lowering post-prandial hyperglycemia and hyperinsulinemia and prevent proximal sodium reabsorption.SGLT2 inhibitors can be used as second-line therapy in patients with diabetes mellitus or heart disease and concomitant hypertension.This article aims to summarize current knowledge regarding the antihypertensive effect of SGLT2 inhibitors and GLP-1 receptor agonists.

Pharmacological inhibition of diacylglycerol acyltransferase-1 and insights into postprandial gut peptide secretion

AIM To examine the role that enzyme Acyl-CoA:diacylglycerol acyltransferase-1(DGAT1) plays in postprandial gut peptide secretion and signaling.METHODS The standard experimental paradigm utilized to evaluate the incretin response was a lipid challenge.Following a lipid challenge,plasma was collected via cardiac puncture at each time point from a cohort of 5-8 mice per group from baseline at time zero to 10 h.Incretin hormones [glucagon like peptide-1(GLP-1),peptide tyrosine-tyrosine(PYY) and glucose dependent insulinotropic polypeptide(GIP)] were then quantitated.The impact of pharmacological inhibition of DGAT1 on the incretin effect was evaluated in WT mice.Additionally,a comparison of loss of DGAT1 function either by genetic ablation or pharmacological inhibition.To further elucidate the pathways and mechanisms involved in the incretin response to DGAT1 inhibition,other interventions [inhibitors of dipeptidyl peptidase-IV(sitagliptin),pancreatic lipase(Orlistat),GPR119 knockout mice] were evaluated.RESULTS DGAT1 deficient mice and wildtype C57/BL6J mice werelipid challenged and levels of both active and total GLP-1 in the plasma were increased.This response was further augmented with DGAT1 inhibitor PF-04620110 treated wildtype mice.Furthermore,PF-04620110 was able to dose responsively increase GLP-1 and PYY,but blunt GIP at all doses of PF-04620110 during lipid challenge.Combination treatment of PF-04620110 and Sitagliptin in wildtype mice during a lipid challenge synergistically enhanced postprandial levels of active GLP-1.In contrast,in a combination study with Orlistat,the ability of PF-04620110 to elicit an enhanced incretin response was abrogated.To further explore this observation,GPR119 knockout mice were evaluated.In response to a lipid challenge,GPR119 knockout mice exhibited no increase in active or total GLP-1 and PYY.However,PF-04620110 was able to increase total GLP-1 and PYY in GPR119 knockout mice as compared to vehicle treated wildtype mice.CONCLUSION Collectively,these data provide some insight into the mechanism by which inhibition of DGAT1 enhances intestinal hormone release.

Oral peptide therapeutics for diabetes treatment: State-of-the-art and future perspectives

Diabetes,characterized by hyperglycemia,is a major cause of death and disability worldwide.Peptides,such as insulin and glucagon-like peptide-1(GLP-1)analogs,have shown promise as treatments for diabetes due to their ability to mimic or enhance insulin's actions in the body.Compared to subcutaneous injection,oral administration of anti-diabetic peptides is a preferred approach.However,biological barriers significantly reduce the efficacy of oral peptide therapeutics.Recent advancements in drug delivery systems and formulation techniques have greatly improved the oral delivery of peptide therapeutics and their efficacy in treating diabetes.This review will highlight(1)the benefits of oral anti-diabetic peptide therapeutics;(2)the biological barriers for oral peptide delivery,including pH and enzyme degradation,intestinal mucosa barrier,and biodistribution barrier;(3)the delivery platforms to overcome these biological barriers.Additionally,the review will discuss the prospects in this field.The information provided in this review will serve as a valuable guide for future developments in oral anti-diabetic peptide therapeutics.

Metabolic disorders in prediabetes:From mechanisms to therapeutic management

Diabetes,one of the world's top ten diseases,is known for its high mortality and complication rates and low cure rate.Prediabetes precedes the onset of diabetes,during which effective treatment can reduce diabetes risk.Prediabetes risk factors include high-calorie and high-fat diets,sedentary lifestyles,and stress.Consequences may include considerable damage to vital organs,including the retina,liver,and kidneys.Interventions for treating prediabetes include a healthy lifestyle diet and pharmacological treatments.However,while these options are effective in the short term,they may fail due to the difficulty of long-term implementation.Medications may also be used to treat prediabetes.This review examines prediabetic treatments,particularly metformin,glucagon-like peptide-1 receptor agonists,sodium glucose cotransporter 2 inhibitors,vitamin D,and herbal medicines.Given the remarkable impact of prediabetes on the progression of diabetes mellitus,it is crucial to intervene promptly and effectively to regulate prediabetes.However,the current body of research on prediabetes is limited,and there is considerable confusion surrounding clinically relevant medications.This paper aims to provide a comprehensive summary of the pathogenesis of prediabetes mellitus and its associated therapeutic drugs.The ultimate goal is to facilitate the clinical utilization of medications and achieve efficient and timely control of diabetes mellitus.

New perspectives in the management of diabetic nephropathy

Diabetic nephropathy(DN)is the leading cause of end-stage renal disease and is also associated with increased risk for cardiovascular events.Until recently,strict glycemic control and blockade of the renin-angiotensin system(RAS)constituted the mainstay of treatment of DN.However,randomized controlled trials showed that sodium-glucose cotransporter 2 inhibitors further reduce the progression of DN.Therefore,these agents are recommended in all patients with DN regardless of DN stage and HbA1c levels.Moreover,additional blockade of the RAS with finerenone,a selective non-steroidal mineralocorticoid receptor antagonist,was also shown to prevent both the decline of renal function and cardiovascular events in this population.Finally,promising preliminary findings suggest that glucagon-like peptide 1 receptor agonists might also exert reno-and cardioprotective effects in patients with DN.Hopefully,this knowledge will improve the outcomes of this high-risk group of patients.

Semaglutide for the management of diabesity:The real-world experience

BACKGROUND Diabesity(diabetes as a consequence of obesity)has emerged as a huge healthcare challenge across the globe due to the obesity pandemic.Judicious use of antidiabetic medications including semaglutide is important for optimal management of diabesity as proven by multiple randomized controlled trials.However,more real-world data is needed to further improve the clinical practice.AIM To study the real-world benefits and side effects of using semaglutide to manage patients with diabesity.METHODS We evaluated the efficacy and safety of semaglutide use in managing patients with diabesity in a large academic hospital in the United States.Several parameters were analyzed including demographic information,the data on improvement of glycated hemoglobin(HbA1c),body weight reduction and insulin dose adjustments at 6 and 12 months,as well as at the latest follow up period.The data was obtained from the electronic patient records between January 2019 to May 2023.RESULTS 106 patients(56 males)with type 2 diabetes mellitus(T2DM),mean age 60.8±11.2 years,mean durations of T2DM 12.4±7.2 years and mean semaglutide treatment for 2.6±1.1 years were included.Semaglutide treatment was associated with significant improvement in diabesity outcomes such as mean weight reductions from baseline 110.4±24.6 kg to 99.9±24.9 kg at 12 months and 96.8±22.9 kg at latest follow up and HbA1c improvement from baseline of 82±21 mmol/mol to 67±20 at 12 months and 71±23 mmol/mol at the latest follow up.An insulin dose reduction from mean baseline of 95±74 units to 76.5±56.2 units was also observed at the latest follow up.Side effects were mild and mainly gastrointestinal like bloating and nausea improving with prolonged use of semaglutide.CONCLUSION Semaglutide treatment is associated with significant improvement in diabesity outcomes such as reduction in body weight,HbA1c and insulin doses without major adverse effects.Reviews of largescale real-world data are expected to inform better clinical practice decision making to improve the care of patients with diabesity.
