Abstract
Importance Thirteen human malignant neoplasms have been identified as obesity-associated cancers (OACs), ie, the presence of excess body fat is associated with increased risk of developing cancer and worse prognosis in patients with these specific tumors. The glucagon-like peptide receptor agonist (GLP-1RA) class of pharmaceuticals are effective agents for the treatment of type 2 diabetes (T2D) and for achieving weight loss, but the association of GLP-1RAs with the incident risk of 13 OACs is unclear. Objective To compare the incident risk of each of the 13 OACs in patients with T2D who were prescribed GLP-1RAs vs insulins or metformin. Design, Setting, and Participants This retrospective cohort study was based on a nationwide multicenter database of electronic health records (EHRs) of 113 million US patients. The study population included 1 651 452 patients with T2D who had no prior diagnosis of OACs and were prescribed GLP-1RAs, insulins, or metformin during March 2005 to November 2018. Data analysis was conducted on April 26, 2024. Exposures Prescription of GLP-1RAs, insulins, or metformin. Main Outcomes and Measures Incident (first-time) diagnosis of each of the 13 OACs occurring during a 15-year follow-up after the exposure was examined using Cox proportional hazard and Kaplan-Meier survival analyses with censoring applied. Hazard ratios (HRs), cumulative incidences, and 95% CIs were calculated. All models were adjusted for confounders at baseline by propensity-score matching baseline covariates. Results In the study population of 1 651 452 patients with T2D (mean [SD] age, 59.8 [15.1] years; 827 873 [50.1%] male and 775 687 [47.0%] female participants; 5780 [0.4%] American Indian or Alaska Native, 65 893 [4.0%] Asian, 281 242 [17.0%] Black, 13 707 [0.8%] Native Hawaiian or Other Pacific Islander, and 1 000 780 [60.6%] White participants), GLP-1RAs compared with insulin were associated with a significant risk reduction in 10 of 13 OACs, including in gallbladder cancer (HR, 0.35; 95% CI, 0.15-0.83), meningioma (HR, 0.37; 95% CI, 0.18-0.74), pancreatic cancer (HR, 0.41; 95% CI, 0.33-0.50), hepatocellular carcinoma (HR, 0.47; 95% CI, 0.36-0.61), ovarian cancer (HR, 0.52; 95% CI, 0.03-0.74), colorectal cancer (HR, 0.54; 95% CI, 0.46-0.64), multiple myeloma (HR, 0.59; 95% CI, 0.44-0.77), esophageal cancer (HR, 0.60; 95% CI, 0.42-0.86), endometrial cancer (HR, 0.74; 95% CI, 0.60-0.91), and kidney cancer (HR, 0.76; 95% CI, 0.64-0.91). Although not statistically significant, the HR for stomach cancer was less than 1 among patients who took GLP-1RAs compared with those who took insulin (HR, 0.73; 95% CI, 0.51-1.03). GLP-1RAs were not associated with a reduced risk of postmenopausal breast cancer or thyroid cancer. Of those cancers that showed a decreased risk among patients taking GLP-1RAs compared with those taking insulin, HRs for patients taking GLP-1RAs vs those taking metformin for colorectal and gallbladder cancer were less than 1, but the risk reduction was not statistically significant. Compared with metformin, GLP-1RAs were not associated with a decreased risk of any cancers, but were associated with an increased risk of kidney cancer (HR, 1.54; 95% CI, 1.27-1.87). Conclusions and Relevance In this study, GLP-1RAs were associated with lower risks of specific types of OACs compared with insulins or metformin in patients with T2D. These findings provide preliminary evidence of the potential benefit of GLP-1RAs for cancer prevention in high-risk populations and support further preclinical and clinical studies for the prevention of certain OACs.

Obes Res Clin Pract 2024; 18:15-20. [PMID: 38199930 DOI: 10.1016/j.orcp.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 10/18/2023] [Accepted: 12/22/2023] [Indexed: 01/12/2024]
Abstract
AIMS To assess the long-term risk of developing type 2 diabetes in patients with obesity who have undergone gastric bypass surgery compared to non-operated patients with obesity and the general population. METHODS This study included 71,495 patients aged 20-65 years with a principal diagnosis of obesity in the Swedish Patient Register in 2001-2013. Of these, 23,099 had undergone gastric bypass and 32,435 had not. Each patient was matched by age, sex and geographic region with two controls from the general population without obesity diagnosis, i.e., 44,735 controls for the gastric bypass cohort and 62,522 controls for the non-operated cohort with obesity. Operated and non-operated patients with obesity were also directly compared using Cox regression analysis, providing hazard ratios (HR) with 95% confidence intervals (CI) adjusted for age, education, and sex. RESULTS During a median follow-up of 4.3 years (interquartile range [IQR] 2.4, 7.0 years), 3792 (11.7%) non-operated patients with obesity developed type 2 diabetes (incidence rate 22.8/1000 person-years, 95% CI 22.1-23.6) compared to 394 (1.7%) among gastric bypass patients (incidence rate 4.0/1000 person-years, 95% CI 3.6-4.5). The latter incidence was comparable to population controls (3.5/1000 person-years, 95% CI 3.2-3.8). Gastric bypass patients had 85% lower risk of diabetes compared to non-operated patients with obesity during the first six years of follow-up (HR 0.15; 95% CI 0.13-0.17). CONCLUSION Gastric bypass surgery for obesity seems to reduce the risk of developing type 2 diabetes to levels similar to that of the general population during the first six years of follow-up but not thereafter.

Obes Facts 2023; 16:457-464. [PMID: 37579738 PMCID: PMC10601677 DOI: 10.1159/000531459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 05/23/2023] [Indexed: 08/16/2023] Open
Abstract
INTRODUCTION Bariatric surgery is a safe and effective treatment for obesity, although in super-obese patients (BMI ≥50 kg/m2) it can become challenging for anatomical and anesthesiologic issues. Several bridging therapies have been proposed to increase preoperative weight loss and decrease perioperative morbidity and mortality. The aim of this study was to compare the efficacy and safety of different two-stage approaches in super-obese patients: laparoscopic sleeve gastrectomy (LSG) following preoperative liraglutide therapy versus LSG with preoperative intragastric balloon (IGB) during a 1-year follow-up. METHODS Clinical records of 86 patients affected by super-obesity who underwent two-stage approach between January 2019 and January 2022 were retrospectively reviewed using a prospectively maintained database. Patients were separated into two groups: those managed with preoperative IGB and those with liraglutide 3.0 mg prior to LSG. Weight (kg), BMI (kg/m2), %EWL, and %EBWL were reported and compared between the two groups at the end of bridging therapy, at 6th month and 12th month postoperatively. Postoperative complications were recorded. RESULTS Forty-four patients underwent IGB insertion prior to LSG, while 42 were treated with liraglutide. There were no statistical differences in baseline weight and BMI. At the end of preoperative treatment, the group treated with IGB reported a significant reduction in BMI (47.24 kg/m2 vs. 53.6 kg/m2; p < 0.391) compared to liraglutide group. There were no differences recorded between the two groups concerning postoperative complications. At 6 months, the liraglutide group had lower %EWL (15.8 vs. 29.84; p < 0.05) and %EBWL (27.8 vs. 55.6; p < 0.05) when compared to IGB group. At 12 months, the IGB preserved with higher %EWL (39.9 vs. 25; p < 0.05) and %EBWL (71.2 vs. 42; p < 0.05). CONCLUSION A two-stage therapeutic approach with IGB prior to LSG in super-obese patients could be considered an attractive alternative to liraglutide as bridging therapy before bariatric surgery.

Abstract
Background Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RA) are frequently used for the management of diabetes. The impact of GLP-1 RA on cardiovascular outcomes is unclear. We aim to assess the effect of GLP-1 RA on mortality, atrial and ventricular arrhythmias, and sudden cardiac death in patients with type II diabetes. Methods We searched databases including Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar and CINAHL, from inception to May 2022, for randomized controlled trials reporting the relationship between GLP-1 RA (including albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, and semaglutide) and mortality, atrial arrhythmias, and the combined incidence of ventricular arrhythmias and sudden cardiac death. The search was not restricted to time or publication status. Results A total of 464 studies resulted from literature search, of which 44 studies, including 78,702 patients (41,800 GLP-1 agonists vs 36,902 control), were included. Follow up ranged from 52 to 208 weeks. GLP-1 RA were associated with lower risk of all-cause mortality (odds ratio 0.891, 95% confidence interval 0.837-0.949; P < 0.01) and reduced cardiovascular mortality (odds ratio 0.88, 95% confidence interval 0.881-0.954; P < 0.01). GLP-1 RA were not associated with increased risk of atrial (odds ratio 0.963, 95% confidence interval 0.869-1.066; P 0.46) or ventricular arrhythmias and sudden cardiac death (odds ratio 0.895, 95% confidence interval 0.706-1.135; P 0.36). Conclusion GLP-1 RA are associated with decreased all-cause and cardiovascular mortality, and no increased risk of atrial and ventricular arrhythmias and sudden cardiac death.

Abstract
INTRODUCTION An association between glucagon-like peptide-1 receptor agonists (GLP1-RA) and risk of pancreatitis and pancreatic cancer has been suggested. Since its first description, several new trials (including three cardiovascular outcome trials) have been published, substantially increasing the available data set. This suggests the need for an update of the previous meta-analysis. EVIDENCE ACQUISITION A Medline search for GLP-1 receptor agonists (exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide, or semaglutide) was performed, collecting all randomized clinical trials, with duration ≥52 weeks, enrolling patients with type 2 diabetes, and comparing a GLP-1 receptor agonist with placebo or any other non-GLP-1 receptor agonist drug. The endpoints were pancreatitis, pancreatic cancer reported as serious adverse events. Mantel-Haenszel Odds Ratio (MH-OR) with 95% confidence interval (95% CI) was calculated for all outcomes defined above, on an intention-to-treat basis. EVIDENCE SYNTHESIS A total of 43 trials fulfilling inclusion criteria (all reporting data on pancreatitis and pancreatic cancer) was identified. GLP-1 RA showed no association with pancreatitis (MH-OR 1.24 [0.94, 1.64]; P=0.13) and pancreatic cancer (MH-OR 1.28 [0.87, 1.89]; P=0.20). CONCLUSIONS No clear evidence of risk for pancreatitis was observed, whereas data on pancreatic cancer are too scarce to draw any conclusion.

Abstract
AIM To clarify the effects of glucose-dependent insulinotropic polypeptide (GIP) receptor agonists (GIPRAs) on feeding and body weight. MATERIALS AND METHODS Acute and subchronic effects of subcutaneous GIPFA-085, a long-acting GIPRA, on blood glucose, food intake, body weight, respiratory exchange ratio and plasma leptin levels were measured in diet-induced obese (DIO) mice and/or functional leptin-deficient ob/ob mice. The effects of GIPFA-085 on the hypothalamic arcuate nucleus (ARC) neurons from lean and DIO mice were studied by measuring cytosolic Ca2+ concentration ([Ca2+ ]i ). RESULTS Single bolus GIPFA-085 (30, 300 nmol/kg) dose-dependently reduced blood glucose in glucose tolerance tests, elevated plasma leptin levels at 0.5-6 hours and inhibited food intake at 2-24 hours after injection in DIO mice. Daily GIPFA-085 (300 nmol/kg) inhibited food intake and increased fat utilization on day 1, and reduced body weight gain on days 3-12 of treatment in DIO, but not ob/ob, mice. GIPFA-085 increased [Ca2+ ]i in the ARC leptin-responsive and proopiomelanocortin (POMC) neurons. GIPFA-085 and leptin cooperated to increase [Ca2+ ]i in ARC neurons and inhibit food intake. CONCLUSIONS GIPFA-085 acutely inhibits feeding and increases lipid utilization, and sustainedly lowers body weight in DIO mice via mechanisms involving rises in leptin and activation of ARC leptin-responsive and POMC neurons. This study highlights the therapeutic potential of GIPRAs for treating obesity and diabetes.

Abstract
Abstract
Type two diabetes has become a civilization disease in the recent years, and the accompanying obesity, metabolic syndrome and non-alcoholic fatty liver are often the inseparable components of the clinical presentation in patients with diabetes of this type. The treatment of each of these elements is important for optimal metabolic control of the patients, as well as directly affecting their life expectancy. However, The ideal solution would be to take as few drugs as possible, preferably drugs that have a beneficial effect on several coexisting diseases at the same time. In the recent years, there have been more and more reports about the pleiotropic effect of drugs affecting the incretin axis - GLP-1 analogues. The presented paper provides an overview of the latest knowledge on the effect of GLP-1 receptor agonists on weight reduction and reduction of changes in the course of non-alcoholic fatty liver disease.

Abstract
AIMS To explore the effect of glucagon-like peptide-1 receptor agonist (GLP-1 RAs) on glycemic control and weight reduction in adults. METHODS Databases were searched from August 2021 to March 2022. Data were analyzed using mean difference (MD) values with 95% confidence intervals (CIs). Both random-and fixed-effect models were employed. Heterogeneity was explored using pre-specified subgroup analyses and meta-regression. Structural equation modeling fitting was used for the multivariate meta-analysis. RESULTS A total of 31 double-blind randomized controlled trials with 22,948 participants were included in the meta-analysis. The MD and 95% CI of the pooled GLP1-RA-induced change in the glycated hemoglobin level was -0.78% (-0.97%, -0.60%) in the random-effects model and -0.45% (-0.47%, -0.44%) in the fixed-effect model, with a high heterogeneity (I2 = 97%). The pooled body weight reduction was -4.05 kg (-5.02 kg, -3.09 kg) in the random-effects model and -2.04 kg (-2.16 kg, -1.92 kg) in the fixed-effect model (I2 = 98%). The standardized pooled correlation coefficient between HbA1c levels and body weight was -0.42. A negative correlation between glycemic control and weight reduction was obtained. CONCLUSION Long-acting GLP-1 RAs significantly reduced the glycated hemoglobin level and body weight in adults.

Abstract
Objectives: This study aims to explore the weight loss effect and safety of semaglutide as a conventional anti-obesity drug systematically in obese or overweight patients without diabetes. Methods: The randomized controlled trials (RCTs) of semaglutide in obese or overweight patients without diabetes were retrieved from PubMed, Cochrane Library, EMBASE, and ClinicalTrials.gov from database inception until 2 May 2022. Data extraction and quality assessment of studies meeting the inclusion criteria were performed, and statistical analysis was conducted by Review Manager 5.3 and Stata 14. Results: Eight studies involving 4,567 patients were enrolled in the meta-analysis. Compared with placebo, semaglutide induced a significant body weight loss (MD: −10.09%; 95% CI: −11.84 to −8.33; p ˂ 0.00001), elicited a larger reduction in body mass index (MD: −3.71 kg/m2; 95% CI: −4.33 to −3.09; p ˂ 0.00001) and waist circumference (MD: −8.28 cm; 95% CI: −9.51 to −7.04; p ˂ 0.00001), achieved weight loss of more than 5, 10, 15, and 20% with a higher proportion of participants. Semaglutide exhibited a positive effect on blood pressure, C-reactive protein, and lipid profiles, expressed more adverse effects than placebo, mainly gastrointestinal reactions. The results were stable and reliable with dose-dependence. Conclusion: Semaglutide indicated a significant weight loss with an acceptable safety for obese or overweight patients without diabetes.

Abstract
Nonalcoholic steatohepatitis (NASH), as a severe form of nonalcoholic fatty liver disease (NAFLD), is characterized by liver steatosis, inflammation, hepatocellular injury and different degrees of fibrosis. The pathogenesis of NASH is complex and multifactorial, obesity and type 2 diabetes mellitus (T2DM) have been implicated as major risk factors. Glucagon-like peptide-1 receptor (GLP-1R) is one of the most successful drug targets of T2DM and obesity, and its peptidic ligands have been proposed as potential therapeutic agents for NASH. In this article we provide an overview of the pathophysiology and management of NASH, with a special focus on the pharmacological effects and possible mechanisms of GLP-1 mimetics in treating NAFLD/NASH, including dual and triple agonists at GLP-1R, glucose-dependent insulinotropic polypeptide receptor or glucagon receptor.

Abstract
CONTEXT Glucagon-like peptide 1 (GLP-1) and α-tocopheryl quinone can promote the growth of intestinal flora and affect the pathogenesis of non-alcoholic steatohepatitis (NASH). OBJECTIVE This study determines the molecular mechanism of the effect of tocopheryl quinone in the treatment of high cholesterol and cholate diet (HFCC)-induced NASH. MATERIALS AND METHODS Thirty-two male Sprague Dawley (SD) rats grouped as lean control (LC), LC + tocopheryl quinone (1 mL of 3 × 106 dpm tocopheryl quinone via i.p. injection), HFCC (5.1 kcal/g of fat diet), and HFCC + tocopheryl quinone. Profiles of intestinal flora were assessed by 16S ribosomal ribonucleic acid-based analysis. Levels and activity of GLP-1, interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α) in intestinal tissues were detected by immunohistochemistry (IHC), Western blot and enzyme-linked immunosorbent assay (ELISA). RESULTS HFCC rats presented higher levels of cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL), while tocopheryl quinone reversed the effects of HFCC. HFCC dysregulated malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), Vitamin E, 12-hydroxyeicosatetraenoic acid (12-HETE), 13-hydroxyoctadecadienoic acid (13-HODE) and nuclear factor kappa B (NF-κB), and the effects of HFCC were reversed by the treatment of tocopheryl quinone. Also, GLP-1 in the HFCC group was down-regulated while the IL-6 and TNF-α activity and endotoxins were all up-regulated. HFCC significantly decreased the number and diversity of bacteria, whereas tocopheryl quinone substantially restored the balance of intestinal flora and promoted the growth of both Bacteroides and Lactobacilli in vitro. DISCUSSION AND CONCLUSIONS α-Tocopheryl quinone relieves HFCC-induced NASH via regulating oxidative stress, GLP-1 expression, intestinal flora imbalance, and the metabolism of glucose and lipids.

Int J Gen Med 2021; 14:8643-8650. [PMID: 34849008 PMCID: PMC8627262 DOI: 10.2147/ijgm.s336904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Accepted: 11/08/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Unmanaged cases of obesity might lead to serious conditions and complications, which impair patients' lives. The aim of this study was to assess the effectiveness and safety of daily 3 mg subcutaneous (s/c) Liraglutide amongst obese non-diabetic patients in Eastern Province, Saudi Arabia. METHODS A retrospective cohort study of obese non-diabetic Saudi patients with obesity managed with s/c Liraglutide 3.0 mg who visited the outpatient clinic in Al Mashfa Hospital, Al Khobar, KSA during 2019-2021. We collected patient data from the electronic reporting system for different parameters. Body weight, hemoglobin A1c %, systolic and diastolic blood pressure mmHg were obtained at baseline and after the intervention. RESULTS Records of 258 patients who were using a daily dose of Liraglutide 3.0 mg s/c for at least four months have been reviewed. The body weight loss of patients who used Liraglutide for four months was 8.1±0.8 kg. Moreover, around 204 patients continued for up to six months. Meanwhile, the mean body weight loss was 13 kg. There was a significant reduction of hemoglobin A1c (HbA1c) % by 0.43%. The majority of patients (94.5%) reported satisfaction with the treatment, while adverse events were mainly nausea, vomiting and constipation. CONCLUSION Daily s/c Liraglutide of 3.0 mg is effective in producing significant body weight reduction in obese non-diabetic Saudi patients with tolerable minimal side effects and may provide health benefits in terms of reduced risk of obesity and its related outcomes.

Abstract
Bariatric surgery has been shown to have a variety of metabolically beneficial effects for patients with type 2 diabetes (T2D), and is now also called metabolic surgery. At the 2nd Diabetes Surgery Summit held in 2015 in London, the indication for bariatric and metabolic surgery was included in the “algorithm for patients with type T2D”. With this background, the Japanese Society for Treatment of Obesity (JSTO), the Japan Diabetes Society (JDS) and the Japan Society for the Study of Obesity (JASSO) have formed a joint committee to develop a consensus statement regarding bariatric and metabolic surgery for the treatment of Japanese patients with T2D. Eventually, the consensus statement was announced at the joint meeting of the 38th Annual Meeting of JSTO and the 41st Annual Meeting of JASSO convened in Toyama on March 21, 2021. In preparing the consensus statement, we used Japanese data as much as possible as scientific evidence to consider the indication criteria, and set two types of recommendation grades, “recommendation” and “consideration”, for items for which recommendations are possible. We hope that this statement will be helpful in providing evidence-based high-quality care through bariatric and metabolic surgery for the treatment of obese Japanese patients with T2D.

Efficacy and safety of glucose-lowering agents in patients with type 2 diabetes: A network meta-analysis of randomized, active comparator-controlled trials. Nutr Metab Cardiovasc Dis 2021; 31:1027-1034. [PMID: 33618919 DOI: 10.1016/j.numecd.2020.12.030] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 12/15/2020] [Accepted: 12/24/2020] [Indexed: 01/27/2023]
Abstract
AIM Aim of the present network meta-analysis (NMA) is the comparison across glucose-lowering drugs (GLA) concerning their effects on glucose control, body weight, hypoglycemia, gastrointestinal adverse events, and quality of life. DATA SYNTHESIS This NMA includes randomized clinical trials comparing different head-to-head comparison trials with EMA-approved GLA in type 2 diabetes, with a duration of ≥52 weeks. All drugs have to be administered at the maximal approved dose. Primary endpoints were HbA1c at 12, 52, and 104+ weeks. Secondary endpoints were body weight, quality of life, hypoglycemia, and gastrointestinal disorders. Indirect comparisons of different GLA were performed by NMA choosing metformin as reference. The standardized difference in means (SDM) and Mantel-Haenzel Odds Ratio [MH-OR] (using random-effect models) with 95% Confidence Intervals were calculated for categorical and continuous variables, respectively. We included 68 trials fulfilling all inclusion criteria. At 12 weeks, when considering indirect comparisons, insulin secretagogues (IS) were associated with a significantly greater reduction in comparison with metformin (SDM, -0.3 [-0.4;-0.2]%); a significantly lower efficacy was observed for pioglitazone. At 52 weeks, IS were no longer associated with a greater reduction of HbA1c; whereas a significant decrease in HbA1c was observed for GLP-1 RA (SDM, -0.2 [-0.1;-0.3]%). At 104+ weeks, only SGLT-2 inhibitors showed a significantly greater HbA1c reduction (SDM, -0.2 [-0.1;-0.3]%), whereas sulfonylureas and insulin showed a significantly lower efficacy (SDM, 0.1 [0.0; 0.2]%), and 0.4 [0.3; 0.5]%, respectively). CONCLUSIONS The results of this meta-analysis should be considered together with evidence on long-term outcomes for selecting the most appropriate drugs for individual patients.

Abstract
Weight loss has been shown to improve metabolic parameters and cardiovascular risk in people with type 2 diabetes mellitus (T2DM). This phase 2 study evaluated the safety and efficacy of JNJ-64565111, a dual agonist of GLP-1 and glucagon receptors, in individuals with T2DM and class II/III obesity. In this randomized, double-blind study, participants with T2DM (HbA1c 6.5%-9.5%), body mass index of 35 to 50 kg/m2 and stable weight were randomly assigned (1:1:1:1) to placebo or JNJ-64565111 (5.0 mg, 7.4 mg or 10.0 mg). The primary endpoint was percent change from baseline in body weight at week 12. Of 195 dosed participants, 144 (73.8%) completed treatment. At week 12, placebo-subtracted body weight changes were -4.6%, -5.9% and -7.2% with JNJ-64565111 5.0 mg, 7.4 mg and 10.0 mg, respectively. All JNJ-64565111 doses were associated with no change in HbA1c and slight numerical elevation of fasting insulin. Numerical increases in fasting plasma glucose were observed with JNJ-64565111 5.0 mg and 7.4 mg. Incidence of treatment-emergent adverse events, especially nausea and vomiting, was higher with JNJ-64565111 vs placebo. Overall, JNJ-64565111 significantly reduced body weight in a dose-dependent manner vs placebo but was associated with greater incidence of treatment-emergent adverse events, no HbA1c reductions, and increased fasting plasma glucose and fasting insulin.

Abstract
Individuals with obesity have a heightened risk of developing serious comorbidities, and pharmacological treatments for people with obesity are limited. This phase 2 study assessed the safety and efficacy of JNJ-64565111, a dual agonist of glucagon-like peptide-1 and glucagon receptors, in individuals with class II/III obesity without type 2 diabetes. In this randomized, double-blind, placebo-controlled and open-label active-controlled, parallel-group, multicentre study, participants aged 18 to 70 years with a body mass index of 35 to 50 kg/m2 and stable weight were randomly assigned in a 1:1:2:2:2 ratio to blinded treatment with placebo; JNJ-64565111 (5.0, 7.4 or 10.0 mg, each with no dose escalation), or open-label liraglutide 3.0 mg. The primary efficacy endpoint was percent change from baseline in body weight at week 26. Four-hundred seventy four participants were randomized and 343 (72.4%) completed treatment. At week 26, placebo-subtracted body weight changes (adjusted for multiplicity) were -6.8%, -8.1% and -10.0% for the JNJ-64565111 5.0 mg, 7.4 mg and 10.0 mg groups, respectively, and -5.8% for the liraglutide group. Incidence of treatment-emergent adverse events, especially nausea and vomiting, was higher in each JNJ-64565111 treatment group compared to placebo and liraglutide. JNJ-64565111 significantly reduced body weight in a dose-dependent manner vs placebo but was associated with greater incidence of treatment-emergent adverse events.

Abstract
INTRODUCTION A meta-analysis was carried out to systematically evaluate the effects of liraglutide on waist circumference, BMI, weight, insulin resistance (IR), Follicle-Stimulating Hormone (FSH), and Luteinizing hormone (LH) levels in obese women with polycystic ovarian syndromes (PCOS). EVIDENCE ACQUISITION Randomized and non-randomized control trials of liraglutide monotherapy and add-on therapy were searched through PUBMED, Web of Science, Cochrane Library, EBSCO, CNKI (China National Knowledge Infrastructure), the Wanfang database, and Google Scholar databases up to May 30, 2020. Information about the impact of liraglutide on polycystic ovarian syndromes (PCOS) related to obese patients was extracted by two reviewers independently, and Revman 5.3 was used for meta-analysis. EVIDENCE SYNTHESIS A total of six studies with 401 women were included in this research. Waist circumference, BMI, weight was significantly reduced by -6.28 cm (95%CI = -7.89, -4.67; P < 0.00001), -2.53 kg/m2 (95%CI = -2.79, -2.27; P < 0.00001) and -4.33 kg (95%CI = -6.05, -2.61; P < 0.00001) after treatment with liraglutide monotherapy or add on therapy. There was a moderate declination in HOMA-IR scores following liraglutide treatment with -0.81 (95%CI = -0.97, -0.64; P < 0.00001). FSH and LH show a decline in the liraglutide group with high heterogeneity (I2 > 95%). CONCLUSIONS For women with PCOS, BMI, weight, and waist circumference were significantly decreased after 12~24 weeks of treatment with liraglutide monotherapy and add-on therapy. Insulin resistance might be improved with the use of liraglutide. Nevertheless, large scale randomized control trials should be carried out to elucidate the long-term outcome in improving the insulin sensitivity of liraglutide treatment.

Abstract
Metformin remains the first-line drug treatment for type 2 diabetes (T2D) in most guidelines not only because it achieves significant reduction in HbA1c but also because of a wealth of clinical experience regarding its safety and observational data that has shown that metformin use is associated with lower mortality rates when compared to sulphonylureas or insulin. Recently other diabetes drugs, particularly SGLT2 inhibitors (SGLT2i) and GLP1 receptor agonists (GLP1RA), have attracted considerable attention for their cardioprotective benefits reported in cardiovascular outcome trials (CVOTs). Randomised control trials on these newer drugs are on a larger scale but have shorter follow-up than UKPDS, the main study supporting metformin use. In a recent change to the European Society of Cardiology guidelines, metformin was replaced by SGLT2i and GLP1RA as first-line for T2D with atherosclerotic cardiovascular disease, whereas American Diabetes Association and UK-wide guidelines maintain metformin as first choice drug pharmacotherapy for all T2D. A definitive evidence-base for prioritisation of these drugs is currently missing because there are no head-to-head clinical trial data. Without such trials being forthcoming, innovative, pragmatic and low-cost 'real-world' trial approaches based on electronic health records may need to be harnessed to determine the correct priority, combinations of drugs and/or identify-specific patient populations most likely to benefit from each one.

Abstract
Obesity is a complex condition that interweaves biological, developmental, environmental, behavioral, and genetic factors; it is a significant public health problem. The most common cause of obesity throughout childhood and adolescence is an inequity in energy balance; that is, excess caloric intake without appropriate caloric expenditure. Adiposity rebound (AR) in early childhood is a risk factor for obesity in adolescence and adulthood. The increasing prevalence of childhood and adolescent obesity is associated with a rise in comorbidities previously identified in the adult population, such as Type 2 Diabetes Mellitus, Hypertension, Non-alcoholic Fatty Liver disease (NAFLD), Obstructive Sleep Apnea (OSA), and Dyslipidemia. Due to the lack of a single treatment option to address obesity, clinicians have generally relied on counseling dietary changes and exercise. Due to psychosocial issues that may accompany adolescence regarding body habitus, this approach can have negative results. Teens can develop unhealthy eating habits that result in Bulimia Nervosa (BN), Binge- Eating Disorder (BED), or Night eating syndrome (NES). Others can develop Anorexia Nervosa (AN) as they attempt to restrict their diet and overshoot their goal of "being healthy." To date, lifestyle interventions have shown only modest effects on weight loss. Emerging findings from basic science as well as interventional drug trials utilizing GLP-1 agonists have demonstrated success in effective weight loss in obese adults, adolescents, and pediatric patients. However, there is limited data on the efficacy and safety of other weight-loss medications in children and adolescents. Nearly 6% of adolescents in the United States are severely obese and bariatric surgery as a treatment consideration will be discussed. In summary, this paper will overview the pathophysiology, clinical, and psychological implications, and treatment options available for obese pediatric and adolescent patients.

Abstract
Type 2 diabetes (T2D) has a complex pathophysiology composed of multiple underlying defects that lead to impaired glucose homeostasis and the development of macrovascular and microvascular complications. Of the currently available glucose-lowering therapies, sodium-glucose cotransporter-2 inhibitors (SGLT-2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) both provide effective glycemic control and have been shown to reduce cardiovascular (CV) events in patients with T2D and a high CV risk or established CV disease. Because these agents have complementary mechanisms of action, they are able to act on multiple defects of T2D when used in combination. This review discusses the rationale for and potential benefits of SGLT-2i plus GLP-1RA combination therapy in patients with T2D. A search of the PubMed database was conducted for studies and reviews describing the combined use of SGLT-2is and GLP-1RAs, with a specific focus on identifying clinical studies of combination therapy in patients with T2D. In clinical studies, glycated hemoglobin (A1c) was significantly reduced over 28-52 weeks with SGLT-2i plus GLP-1RA therapy versus the individual agents or baseline. Several CV risk factors, including body weight, blood pressure, and lipid parameters, were also improved. SGLT-2i plus GLP-1RA therapy was generally well tolerated, with a low risk of hypoglycemia and no unexpected findings. Taken together with results from large CV outcomes trials of SGLT-2is and GLP-1RAs, combination therapy with these agents potentially provides effective durable glycemic control and CV benefits due to their complementary actions on the defects of T2D.

Abstract
Sodium glucose cotransporter (SGLT)-2 inhibitors are the newest addition to our treatment armamentarium for the management of hyperglycemia in type 2 diabetes. Glucose-lowering per se reduces the risk of microvascular complications, but not the risk of cardiovascular disease, including heart failure and cardiovascular mortality. Also, even when embedded in optimal cardiovascular prevention, a large residual risk remains with respect to progression of diabetic kidney disease. SGLT-2 inhibitors lower blood glucose levels by inducing glucosuria. Through various proposed mechanisms, among which diuretic and natriuretic effects, SGLT-2 inhibitors decrease heart failure hospitalization, reduce cardiovascular mortality, and mitigate progression of diabetic kidney disease. In this perspective, we will discuss the glucose-lowering and other protective effects of SGLT-2 inhibitors on the cardiorenal axis, both in primary and secondary prevention. By comparing the glycemic and pleiotropic effects of these agents to other glucose-lowering drugs, we will address questions around whether SGLT-2 inhibitors should be considered primarily as glucose-lowering agents, cardiorenal drugs or both.

Thromboxane-Dependent Platelet Activation in Obese Subjects with Prediabetes or Early Type 2 Diabetes: Effects of Liraglutide- or Lifestyle Changes-Induced Weight Loss. Nutrients 2018; 10:nu10121872. [PMID: 30513818 PMCID: PMC6315606 DOI: 10.3390/nu10121872] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Revised: 11/20/2018] [Accepted: 11/26/2018] [Indexed: 12/17/2022] Open
Abstract
Thromboxane (TX)-dependent platelet activation and lipid peroxidation, as reflected in vivo by the urinary excretion of 11-dehydro-TXB2 and 8-iso-prostaglandin (PG)F2α, play a key role in atherothrombosis in obesity and type 2 diabetes mellitus (T2DM) since the earlier stages. Thirty-five metformin-treated obese subjects with prediabetes or newly-diagnosed T2DM were randomized to the glucagon-like peptide receptor agonist (GLP-RA) liraglutide (1.8 mg/day) or lifestyle counseling until achieving a comparable weight loss (−7% of initial body weight), to assess whether changes in subcutaneous (SAT) and visceral (VAT) adipose tissue distribution (MRI), insulin sensitivity (Matsuda Index) and beta-cell performance (multiple sampling OGTT beta-index), with either intervention, might affect TX-dependent platelet activation, lipid peroxidation and inflammation. At baseline, Ln-8-iso-PGF2α (Beta = 0.31, p = 0.0088), glycosylated hemoglobin (HbA1c) (Beta = 2.64, p = 0.0011) Ln-TNF-α (Beta = 0.58, p = 0.0075) and SAT (Beta = 0.14, p = 0.044) were significant independent predictors of 11-dehydro-TXB2. After achievement of the weight loss target, a comparable reduction in U-11-dehydro-TXB2 (between-group p = 0.679) and 8-iso-PGF-2α (p = 0.985) was observed in both arms in parallel with a comparable improvement in glycemic control, insulin sensitivity, SAT, high-sensitivity C-reactive protein (hs-CRP). In obese patients with initial impairment of glucose metabolism, the extent of platelet activation is related to systemic inflammation, isoprostane formation and degree of glycemic control and abdominal SAT. Successful weight loss, achieved with either lifestyle changes or an incretin-based therapy, is associated with a significant reduction in lipid peroxidation and platelet activation.

Abstract
INTRODUCTION Based on existing data regarding the durability of liraglutide in type 2 diabetes, this study aimed to assess its long-term effectiveness at 5 years and its overall impact on cardiovascular (CV) risk. METHODS This was a multicenter retrospective observational study. Liraglutide was used under routine clinical practice conditions. Changes from baseline to 60 months in HbA1c, fasting plasma glucose (FPG), body weight, blood pressure, and lipid profile were assessed. United Kingdom Prospective Diabetes Study (UKPDS) scores were calculated at baseline and after 60 months to assess changes in the estimated 5- and 10-year risk for fatal and nonfatal coronary heart disease (CHD) and fatal and nonfatal stroke. RESULTS Overall, 103 patients (age 59.0 ± 7.9 years, diabetes duration 10.4 ± 6.8 years) were involved in the study. After 60 months, HbA1c levels were reduced by - 1.0 ± 1.2%, FPG levels by - 24.5 ± 43.4 mg/dl, body weight by - 5.3 ± 6.4 kg, systolic blood pressure by - 6.5 ± 18.5 mmHg, diastolic blood pressure by - 3.6 ± 11.8 mmHg, and total cholesterol by - 16.9 ± 37.4 mg/dl. The proportion of patients achieving HbA1c levels of < 7% increased from 12.7% to 39.8% (p = 0.02). Based on the UKPDS scores, statistically significant reductions in the 5- and 10-year risk of nonfatal CHD and fatal CHD were found, with no change in the 5- and 10-year risk of fatal and nonfatal stroke. CONCLUSION In patients prolonging treatment with liraglutide for 5 years, the benefits in relation to metabolic control and CV risk factors are maintained. The UKPDS risk scores suggest that liraglutide is associated with a reduced CHD risk, but not with a reduced stroke risk.

Identification of therapeutic effect of glucagon-like peptide 1 in the treatment of STZ-induced diabetes mellitus in rats by restoring the balance of intestinal flora.

Abstract
OBJECTIVE The objective of this study was to identify the therapeutic effect and the underlying mechanism of glucagon-like peptide 1 (GLP-1) in the treatment of STZ-induced diabetes mellitus (DM). METHODS Mice were treated with STZ to establish an animal model of DM, which was further treated with a GLP-1 receptor agonist. Subsequently, the status of glucose, insulin, nitric oxide, inflammatory and oxidative factors was evaluated and compared among Sham, STZ, and STZ + GLP-1 groups. In addition, the intestinal flora spectrum in each group was also evaluated. RESULTS In this study, it was found that the administration of STZ increased the level of glucose and glycosylated hemoglobin but reduced the level of insulin. It was also found that the levels of inflammation and oxidative stress in STZ-induced DM were both enhanced, as evidenced by a decreased level of catalase, superoxide dismutase, glutathione peroxidase, as well as increased levels of malonyldialdehyde, interleukin-1β (IL-1β), and IL-6. Meanwhile, the expression of nitric oxide, a factor associated with both oxidative stress and inflammation, was also suppressed in STZ-induced DM. More importantly, the imbalance of intestinal flora was observed in STZ-induced DM, as shown by a decreased level of both total bacteria and that of some strains including Clostridium, Bacteroides, Lactobacilli, and Bifidobacteria. CONCLUSION In summary, the findings of this study confirmed the antihyperglycemic effect of GLP-1 and demonstrated that the therapeutic effect of GLP-1 in the treatment of STZ-induced DM was mediated, at least partially, by its ability to restore the balance of intestinal flora.

Abstract
The incretin therapies glucagon-like peptide-1 receptor agonists (GLP-1 RA) and dipeptidyl peptidase-IV (DPP-IV) inhibitors are now well-established as second and third-line therapies and in combination with insulin for the treatment of type 2 diabetes. Over the last decade, there is accumulating evidence of their efficacy and safety from both large multicentre randomized clinical trials (RCT) and observational studies. Cardiovascular outcome trials have confirmed that several of these agents are also non-inferior to placebo with the GLP-1 RA liraglutide and semaglutide recently found to be superior in terms of major adverse cardiovascular events. Observational studies and post-marketing surveillance provide real world evidence of safety and effectiveness of these agents and have provided reassurance that signals for pancreatitis and pancreatic cancer seen in clinical trials are not of major concern in large patient populations. Well-designed real world studies complement RCTs and systematic reviews but appropriate data and methodologies, which are constantly improving, are necessary to answer appropriate clinical questions relating to the use of incretin therapies.

Abstract
The glucagon-like peptide-1 receptor agonists (GLP-1RAs) were recommended as a monotherapy or combination therapy with oral hypoglycemic agents or basal insulin in the position statement of the Korean Diabetes Association 2017 for pharmacological therapy. Many randomized clinical trials and systematic reviews report that GLP-1RAs have considerable glucose-lowering effect and lead to weight reduction and low risk of hypoglycemia when used as a monotherapy or combination therapy. The cardiovascular safety of GLP-1RAs has been assessed in several randomized clinical trials and systematic reviews. The results of cardiovascular outcome trials of long-acting GLP-1RAs (liraglutide, semaglutide) demonstrated cardiovascular benefits in subjects with type 2 diabetes mellitus and a high risk of cardiovascular disease. The GLP-1RA may be a choice of therapy when weight control and avoidance of hypoglycemia are important, and patients with high risk of cardiovascular disease might also favor choosing GLP-1RA.

Abstract
AIMS Results with GLP1-receptor agonists (GLP-1RA) on microvascular complications of diabetes are contrasting. In trials designed for cardiovascular outcomes, both liraglutide and semaglutide were associated with a relevant reduction in the incidence and progression of nephropathy. On the other hand, in the same trials, semaglutide was associated with an increased progression of retinopathy, and a similar trend was observed for liraglutide. This meta-analysis is aimed at assessing the effects of GLP-1RA on retinopathy and nephropathy. METHODS A Medline search for GLP-1 receptor agonists (exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide, or semaglutide) was performed, collecting all randomized clinical trials with a duration >11 weeks, enrolling patients with type 2 diabetes, and comparing a GLP-1 receptor agonist with placebo or any other non-GLP-1 receptor agonist drug. RESULTS Of the 113 trials fulfilling the inclusion criteria, 78 and 62 did not report information on retinopathy and nephropathy, respectively. Treatment with GLP1-RA was not associated with a significant increase in the incidence of retinopathy (MH-OR [95% CI] 0.92 [0.74-1.16]. p = 0.49). In subgroup analyses, GLP1-RA were associated with a lower risk of retinopathy in comparison with sulfonylureas. Cases of macular edema were reported only in nine trials with no sign of increased risk. GLP1-RA reduced the incidence of nephropathy with respect to comparators (MH-OR [95% CI] 0.74 [0.60-0.92]. p = 0.005). This difference was significant versus placebo, but not versus any class of active comparators. CONCLUSIONS GLP1-RA appear to reduce the incidence and/or progression of nephropathy and to have no specific effect on retinopathy-with the notable exception of semaglutide, which could have a negative impact on the retina.

Abstract
Potentiation of glucagon-like peptide-1 (GLP-1) action through selective GLP-1 receptor (GLP-1R) agonism or by prevention of enzymatic degradation by inhibition of dipeptidyl peptidase-4 (DPP-4) promotes glycemic reduction for the treatment of type 2 diabetes mellitus by glucose-dependent control of insulin and glucagon secretion. GLP-1R agonists also decelerate gastric emptying, reduce body weight by reduction of food intake and lower circulating lipoproteins, inflammation, and systolic blood pressure. Preclinical studies demonstrate that both GLP-1R agonists and DPP-4 inhibitors exhibit cardioprotective actions in animal models of myocardial ischemia and ventricular dysfunction through incompletely characterized mechanisms. The results of cardiovascular outcome trials in human subjects with type 2 diabetes mellitus and increased cardiovascular risk have demonstrated a cardiovascular benefit (significant reduction in time to first major adverse cardiovascular event) with the GLP-1R agonists liraglutide (LEADER trial [Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Ourcome Results], -13%) and semaglutide (SUSTAIN-6 trial [Trial to Evaluate Cardiovascular and Other Long-term Outcomes with Semaglutide], -24%). In contrast, cardiovascular outcome trials examining the safety of the shorter-acting GLP-1R agonist lixisenatide (ELIXA trial [Evaluation of Lixisenatide in Acute Coronary Syndrom]) and the DPP-4 inhibitors saxagliptin (SAVOR-TIMI 53 trial [Saxagliptin Assessment of Vascular Outcomes Recorded in Patients With Diabetes Mellitus-Thrombolysis in Myocardial Infarction 53]), alogliptin (EXAMINE trial [Examination of Cardiovascular Outcomes With Alogliptin Versus Standard of Care in Patients With Type 2 Diabetes Mellitus and Acute Coronary Syndrome]), and sitagliptin (TECOS [Trial Evaluating Cardiovascular Outcomes With Sitagliptin]) found that these agents neither increased nor decreased cardiovascular events. Here we review the cardiovascular actions of GLP-1R agonists and DPP-4 inhibitors, with a focus on the translation of mechanisms derived from preclinical studies to complementary findings in clinical studies. We highlight areas of uncertainty requiring more careful scrutiny in ongoing basic science and clinical studies. As newer more potent GLP-1R agonists and coagonists are being developed for the treatment of type 2 diabetes mellitus, obesity, and nonalcoholic steatohepatitis, the delineation of the potential mechanisms that underlie the cardiovascular benefit and safety of these agents have immediate relevance for the prevention and treatment of cardiovascular disease.

Abstract
AIM Glucagon-like peptide 1 receptor agonists (GLP1-RA) have been associated with an increased risk of pancreatitis and pancreatic cancer. Prior meta-analyses of randomized controlled trials failed to show any significant increase of risk; however, those meta-analyses did not include the recently published cardiovascular outcome trials (CVOT) with GLP1-RA, which provide a substantial additional body of data. The aim of the present meta-analysis is to assess the effect of GLP1-RA on pancreatitis, pancreatic cancers and cholelithiasis. MATERIALS AND METHODS A Medline search for GLP-1 receptor agonists (exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide or semaglutide) was performed, collecting all randomized clinical trials with a duration >11 weeks, enrolling patients with type 2 diabetes and comparing a GLP-1 receptor agonist with placebo or any other non-GLP-1 receptor agonist drug. RESULTS Of the 113 trials fulfilling inclusion criteria, 13 did not report information on pancreatitis, whereas 72 reported no events in all treatment groups. The incidence of pancreatitis and pancreatic cancer with GLP1-RA was not significantly different from that observed in comparator arms (MH-OR [95% CI] 0.93 [0.65-1.34], P = .71, and 0.94 [0.52-1.70], P = .84, respectively), whereas, a significantly increased risk of cholelithiasis (MH-OR [95% CI] 1.30 [1.01-1.68], P = .041) was detected. CONCLUSIONS Presently available data confirm the safety of GLP-1 receptor agonists for pancreatitis. Conversely, therapy with those drugs is associated with an increased risk of cholelithiasis, which deserves further investigation.

Abstract
AIMS To compare efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in people with type 2 diabetes. MATERIALS AND METHODS We electronically searched, up to June 3, 2016, published randomized clinical trials lasting between 24 and 32 weeks that compared a GLP-1RA (albiglutide, dulaglutide, twice-daily exenatide and once-weekly exenatide, liraglutide, lixisenatide, semaglutide and taspoglutide) with placebo or another GLP-1RA. Data on cardiometabolic and safety outcomes were analysed using a mixed-treatment comparison meta-analysis. RESULTS A total of 34 trials (14 464 participants) met the inclusion criteria; no published data for semaglutide were available. Compared with placebo, all GLP-1RAs reduced glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) levels (reductions ranged from -0.55% and -0.73 mmol/L, respectively, for lixisenatide to -1.21% and -1.97 mmol/L, respectively, for dulaglutide). There were no differences within short-acting (twice-daily exenatide and lixisenatide) or long-acting (albiglutide, dulaglutide, once-weekly exenatide, liraglutide and taspoglutide) groups. Compared with twice-daily exenatide, dulaglutide treatment was associated with the greatest HbA1c and FPG reduction (0.51% and 1.04 mmol/L, respectively), followed by liraglutide (0.45% and 0.93 mmol/L, respectively) and once-weekly exenatide (0.38% and 0.85 mmol/L, respectively); similar reductions were found when these 3 agents were compared with lixisenatide. Compared with placebo, all GLP-1RAs except albiglutide reduced weight and increased the risk of hypoglycaemia and gastrointestinal side effects, and all agents except dulaglutide and taspoglutide reduced systolic blood pressure. When all GLP-1RAs were compared with each other, no clinically meaningful differences were observed in weight loss, blood pressure reduction or hypoglycaemia risk. Albiglutide had the lowest risk of nausea and diarrhoea and once-weekly exenatide the lowest risk of vomiting. CONCLUSIONS The RCTs in the present analysis show that all GLP-1RAs improve glycaemic control, reduce body weight and increase the risk of adverse gastrointestinal symptoms compared with placebo. Although there were no differences when short-acting agents were compared with each other or when long-acting agents were compared with each other, dulaglutide, liraglutide and once-weekly exenatide were superior to twice-daily exenatide and lixisenatide at lowering HbA1c and FPG levels. There were no differences in hypoglycaemia between these 3 agents, whilst once-weekly exenatide had the lowest risk of vomiting. These results, along with patient's preferences and individualized targets, should be considered when selecting a GLP-1RA.

A meta-analysis comparing clinical effects of short- or long-acting GLP-1 receptor agonists versus insulin treatment from head-to-head studies in type 2 diabetic patients. Diabetes Obes Metab 2017; 19:216-227. [PMID: 27717195 DOI: 10.1111/dom.12804] [Citation(s) in RCA: 107] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2016] [Revised: 09/07/2016] [Accepted: 09/16/2016] [Indexed: 12/25/2022]
Abstract
AIMS To study differences in clinical outcomes between initiating glucagon-like peptide-1 receptor agonist (GLP-1 RAs) vs insulin treatment in patients with type 2 diabetes treated with oral glucose-lowering medications (OGLM). METHODS Prospective, randomized trials comparing GLP-1 RA and insulin treatment head-to-head as add-on to OGLM were identified (PubMed). Differences from baseline values were compared for HbA1c, fasting plasma glucose, bodyweight, blood pressure, heartrate and lipoproteins. Proportions of patients reporting hypoglycaemic episodes were compared. RESULTS Of 712 publications identified, 23 describing 19 clinical trials were included in the meta-analysis. Compared to insulin, GLP-1 RAs reduced HbA1c more effectively (Δ -.12%, P < .0001). Basal insulin was more effective in reducing fasting plasma glucose (Δ -1.8 mmol/L, P < .0001). GLP-1 RAs reduced bodyweight more effectively (Δ -3.71 kg; P < .0001). The proportion of patients experiencing hypoglycaemic episodes was 34% lower with GLP-1 RAs ( P < .0001), with a similar trend for severe hypoglycaemia. Systolic blood pressure was lower and heartrate was higher with GLP-1 RAs ( P < .0001). Triglycerides and LDL cholesterol were significantly lower with GLP-1 RAs. Long-acting GLP-1 RAs were better than short-acting GLP-1 RAs in reducing HbA1c and fasting glucose, but were similar regarding bodyweight. CONCLUSIONS Slightly better glycaemic control can be achieved by adding GLP-1 RAs to OGLM as compared to insulin treatment, with added benefits regarding bodyweight, hypoglycaemia, blood pressure and lipoproteins. These differences are in contrast to the fact that insulin is prescribed far more often than GLP-1 RAs.

Abstract
Introduction Regulatory requirements mandate that new drugs for treatment of patients with type 2 diabetes mellitus (T2DM), such as dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists, are evaluated to show that they do not increase cardiovascular (CV) risk. Methods A systematic review was undertaken to evaluate the association between DPP-4 inhibitor and GLP-1 receptor agonist use and major adverse cardiac events (MACE). The National Institutes of Health Medline database was searched for pooled analyses, meta-analyses, and randomized controlled trials (RCTs) of DPP-4 inhibitors and GLP-1 receptor agonists that included CV endpoints. Results Thirty-six articles met the inclusion criteria encompassing 11 pooled analyses, 17 meta-analyses, and eight RCTs (including secondary analyses). Over the short term (up to 4 years), patients with T2DM exposed to a DPP-4 inhibitor or GLP-1 receptor agonist were not at increased risk for MACE (or its component endpoints) compared with those who received comparator agents. Two meta-analyses showed a significant reduction in the incidence of MACE associated with DPP-4 inhibitor therapy as a drug class, but this beneficial effect was not observed in other meta-analyses that included large RCT CV outcome studies. In four RCTs that evaluated alogliptin, saxagliptin, sitagliptin, or lixisenatide, there was no overall increased risk for MACE relative to placebo in T2DM patients at high risk for CV events or with established CV disease, although there was an increased rate of hospitalization for heart failure associated with saxagliptin. A fifth RCT showed that liraglutide reduced MACE risk by 13% versus placebo. Conclusion Overall, incretin therapy does not appear to increase risk for MACE in the short term.

Abstract
Objective To review the efficacy, safety, and clinical applicability of liraglutide for weight management from phase III clinical trials. Methods A search of the English language literature was performed using PubMed search terms: “liraglutide”, “glucagon‐like peptide‐1 receptor agonist”, and “randomized clinical trial”. Articles and bibliographies relevant to the subject were reviewed and additional references known to the authors were included. Results Five randomized, placebo‐controlled trials of liraglutide for weight management were identified. In addition to recommended diet and physical activity, liraglutide consistently resulted in a 4 to 6 kg weight loss, with a greater proportion of patients achieving at least 5 and 10% weight loss compared with placebo. The most common adverse effects were gastrointestinal and primarily occurred early in the treatment course. Comparative data suggest that weight loss with liraglutide is greater than that seen with orlistat or lorcaserin, but slightly less that seen with phentermine/topiramate. Liraglutide 1.8 mg was recently shown to have cardiovascular benefit in a large outcomes trial; applicability of these results for the 3.0 mg formulation in a more diverse weight loss population at high cardiovascular risk is not currently known. Barriers to real‐world clinical use as a first‐line agent include gastrointestinal side effects, high cost, and need for injection. Conclusions Liraglutide helps to induce and sustain weight loss in patients with obesity. Its efficacy is comparable to other available agents but it offers the unique benefit of improved glycemic control. Additional studies are needed to determine its long term efficacy and safety profile.

Abstract
Though the pathophysiology of clinical obesity is undoubtedly 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 anti-obesity medications. Generally well tolerated, provided that longer-term data in clinical practice supports the currently available evidence of superior short- and long-term 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.

Abstract
Combining insulin with glucagon-like peptide-1 (GLP-1) receptor agonists or dipeptidyl peptidase-4 (DPP-4) inhibitors as glucose-lowering therapy for type 2 diabetes is a promising strategy that has gained considerable interest over the past few years. One advantage of this combination is the complementary mechanistic actions of insulin and GLP-1. Insulin increases glucose utilization and retards hepatic glucose production through direct actions in muscle, adipose tissue and the liver. On the other hand, GLP-1 stimulates insulin secretion, inhibits glucagon secretion and retards gastric emptying. Combining these effects results in powerful reductions in both fasting and postprandial glucose through diminished glucose entry into the bloodstream after food consumption, reduced hepatic production of glucose and increased glucose utilization. In addition, GLP-1 receptor agonists induce satiety, leading to decreases in food intakes and body weight, thereby preventing the weight gain often seen with insulin therapy. Clinical trials have verified that these physiological effects as a result of combining insulin with GLP-1 receptor agonists or DPP-4 inhibitors can indeed result in improved glycaemia, with limited risks of hypoglycaemia and weight gain.

Abstract
The incretin hormone glucagon-like peptide-1 (GLP-1) binds to and activates its G-protein-coupled-receptor GLP-1R to reduce glycaemia through the stimulation of insulin and suppression of pancreatic glucagon secretion. Recently, GLP-1 effects unrelated to glucose homeostasis have been discovered in myocardium, bone, adipose tissue, and other target organs, which appear to be mainly mediated by GLP-1R-independent pathways. Here, we summarize knowledge on GLP-1R agonists (GLP-1RAs) as they relate to the improvement of glucose control, and focus on the most recently described effects, discussing the preclinical evidence of the involvement of alternative receptors and signalling mechanisms. It is now evident that the universe of GLP-1RAs is expanding further from the initial incretin effect, opening new unforeseen avenues for research and clinical applications.

Efficacy and safety of dulaglutide in patients with type 2 diabetes: a meta-analysis and systematic review. Sci Rep 2016; 6:18904. [PMID: 26742577 PMCID: PMC4705511 DOI: 10.1038/srep18904] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2015] [Accepted: 10/12/2015] [Indexed: 02/05/2023] Open
Abstract
A meta-analysis was conducted to assess the clinical efficacy and safety of dulaglutide in patients with type 2 diabetes mellitus (T2DM). Medline, Embase, Cochrane Library and www. clinicaltrials. gov (up to February 15th, 2015) were searched. Randomized controlled trials comparing dulaglutide to other drugs for T2DM were collected. Twelve RCTs were included, and the overall bias was low. As the monotherapy, compared with control (placebo, metformin and liraglutide), dulaglutide resulted in a significant reduction in HbA1c (WMD, −0.68%; 95% CI, −0.95 to −0.40), FPG (WMD, −0.90 mmol/L; 95% CI, −1.28 to −0.52), a similar risk of hypoglycemia (7.8% vs. 10.6%), less body weight loss (WMD, 0.51 kg; 95% CI, 0.27 to 0.75). As an add-on intervention with oral antihyperglycemic medication (OAM) and insulin, compared with control (placebo, sitagliptin, exenatide, liraglutide and glargine), dulaglutide lowered HbA1c (WMD, −0.51%; 95% CI, −0.68 to −0.35) and body weight significantly (WMD, −1.30 kg, 95% CI, −1.85 to −1.02) notably, and elicited a similar reduction in FPG (WMD, −0.19 mmol/L; 95% CI, −1.20 to 0.82), an similar incidence of hypoglycemia (24.5% vs. 24.5%). This meta-analysis revealed the use of dulaglutide as a monotherapy or an add-on to OAM and lispro appeared to be effective and safe for adults with T2DM.

Abstract
INTRODUCTION Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly being used for the treatment of type 2 diabetes mellitus, but consideration of benefits and potential adverse events is required. This review examines the state of glycemic control, weight loss, blood pressure, and tolerability, as well as the current debate about the safety of GLP-1 RAs, including risk of pancreatitis, pancreatic cancer, and thyroid cancer. METHODS A MEDLINE search (2010-2015) identified publications that discussed longer-acting GLP-1 RAs. Search terms included GLP-1 receptor agonists, liraglutide, exenatide, lixisenatide, semaglutide, dulaglutide, albiglutide, efficacy, safety, pancreatitis, pancreatic cancer, and thyroid cancer. Abstracts from the American Diabetes Association, European Association for the Study of Diabetes, and American Association of Clinical Endocrinologists from 2010 to 2015 were also searched. Efficacy and safety studies, pooled analyses, and meta-analyses were prioritized. RESULTS Research has confirmed that GLP-1 RAs provide robust glycemic control, weight loss, and blood pressure re-duction. Current studies do not prove increased risk of pancreatitis, pancreatic cancer, or thyroid cancer but more trials are needed since publications that indicate safety or suggest increased risk have methodological flaws that prevent firm conclusions to be drawn about these rare, long-term events. CONCLUSION GLP-1 RA therapy in the context of individualized, patient-centered care continues to be supported by current literature. GLP-1 RA therapy provides robust glycemic control, blood pressure reduction, and weight loss, but studies are still needed to address concerns about tolerability and safety, including pancreatitis and cancer.

Abstract
Pediatric obesity is highly prevalent in developed countries globally (and worsening in developing countries) and threatens to shorten the lifespan of the current generation. At highest risk for weight-related comorbidities including Type 2 diabetes mellitus, non-alcoholic fatty liver disease and dyslipidemia is a sub-set of children with severe obesity, often defined as a body mass index (BMI) percentile ≥99th percentile for age and sex. The pathophysiology of severe obesity in childhood is complex, resulting from the dynamic interplay of a myriad of individual and societal factors including genetic predisposition and health behaviors contributing to energy imbalance. Approximately 4–6% of children have severe obesity, representing a common scenario encountered by providers, and intervention is critical to halt ongoing weight gain and, when possible, reverse the trend. Clinical approaches promoting behavioral weight loss may result in modest, albeit clinically significant, reductions in BMI; however, such changes are often difficult to maintain long-term. Data regarding the impact of targeted pharmacotherapy including agents such as orlistat are limited in the pediatric population and again only suggest modest results. However, increasing evidence suggest that surgical treatment, as an adjunct to ongoing lifestyle changes, may be a promising option in carefully-screened adolescents with severe obesity and weight-related comorbidities who are motivated to adhere to the long-term treatment needs.

Abstract
BACKGROUND The high prevalence of obesity (24% of the adult population) and its adverse effects on health call for effective prevention and treatment. METHOD Pertinent articles were retrieved by a systematic literature search for the period 2005 to 2012. A total of 4495 abstracts were examined. 119 publications were analyzed, and recommendations were issued in a structured consensus procedure by an interdisciplinary committee with the participation of ten medical specialty societies. RESULTS Obesity (body-mass index [BMI] ge;30 kg/m2) is considered to be a chronic disease. Its prevention is especially important. For obese persons, it is recommended that a diet with an energy deficit of 500 kcal/day and a low energy density should be instituted for the purpose of weight loss and stabilization of a lower weight. The relative proportion of macronutrients is of secondary importance for weight loss. If the BMI exceeds 30 kg/m2, formula products can be used for a limited time. More physical exercise in everyday life and during leisure time promotes weight loss and improves risk factors and obesity-associated diseases. Behavior modification and behavioral therapy support changes in nutrition and exercise in everyday life. With respect to changes in lifestyle, there is no scientific evidence to support any particular order of the measures to be taken. Weight-loss programs whose efficacy has been scientifically evaluated are recommended. Surgical intervention is more effective than conservative treatment with respect to reduction of bodily fat, improvement of obesity-associated diseases, and lowering mortality. Controlled studies indicate that, within 1 to 2 years, a weight loss of ca. 4 to 6 kg can be achieved by dietary therapy, 2 to 3 kg by exercise therapy, and 20 to 40 kg by bariatric surgery. CONCLUSION There is good scientific evidence for effective measures for the prevention and treatment of obesity.

Abstract
A small library of truncated/lipid-conjugated neuromedin U (NmU) analogs was synthesized and tested in vitro using an intracellular calcium signaling assay. The selected, most active analogs were then tested in vivo, and showed potent anorexigenic effects in a diet-induced obese (DIO) mouse model. The most promising compound, NM4-C16 was effective in a once-weekly-dose regimen. Collectively, our findings suggest that short, lipidated analogs of NmU are suitable leads for the development of novel anti-obesity therapeutics.

Abstract
AIMS/HYPOTHESIS Canagliflozin, a sodium glucose co-transporter 2 inhibitor, reduces HbA1c, body weight and systolic BP (SBP) in patients with type 2 diabetes. As weight loss is known to reduce both HbA1c and SBP, these analyses were performed to evaluate the contribution of weight loss resulting from treatment with canagliflozin to HbA1c and SBP reductions in patients with type 2 diabetes. METHODS Pooled data from four placebo-controlled Phase 3 studies (N = 2,250) in patients with type 2 diabetes were used in the analyses. In each study, patients were treated with placebo, canagliflozin 100 mg or canagliflozin 300 mg, once daily for 26 weeks. Changes from baseline in body weight, HbA1c and SBP were measured at week 26, and the contribution of weight loss to the lowering of HbA1c and SBP was obtained using ANCOVA. RESULTS Canagliflozin 100 and 300 mg reduced mean body weight, HbA1c and SBP compared with placebo (p < 0.001 for each), and more patients had body-weight reductions >0%, ≥5% and ≥10% with canagliflozin treatment than with placebo. Weight-loss-independent and weight-loss-associated mechanisms contributed to HbA1c and SBP lowering with canagliflozin: ~85% of HbA1c lowering and ~60% of SBP lowering was independent of weight loss. CONCLUSIONS/INTERPRETATION In patients with type 2 diabetes, canagliflozin provided clinically meaningful body-weight reductions, and the weight loss contributed to reductions in HbA1c and SBP.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists (GLP-1RAs) benefit weight maintenance for diabetic patients. We performed a systematic review to evaluate its weight loss effect on obese/overweight patients without diabetes in randomized controlled trials (RCTs). METHODS Literature updated to May 5, 2014 from Cochrane Library, MEDLINE, EMBASE and reference lists from relevant articles were identified. RCTs with GLP-1 mimetics treating obese/overweight adults without diabetes for at least 12 weeks were assessed. Studies lacking primary measurements were excluded. Three authors extracted data independently. Either fixed-effect or random-effect models were used to calculate weighted mean differences (WMDs), combined relative risks (RR) and 95% confidence interval (CI) in meta-analyses. Intertrial heterogeneity across studies was examined by I(2) and Q statistics. RESULTS A total of 1345 individuals retrieved from eight studies were involved and all included trials were of mild-to-moderate bias risks. Participants in GLP-1RA groups achieved a larger weight loss than those in control groups (-2.85 kg, 95%CI -3.55 to -2.14), and liraglutide may work in a dose-dependent fashion. GLP-1RAs also reduced body mass index (BMI) and waist circumferences (WC) and benefited systolic blood pressure and triglyceride regulation. But GLP-1RAs were associated with increased nausea and vomiting events. CONCLUSIONS GLP-1 mimetics induce a weight loss in addition to BMI and WC reduction in obese/overweight adults without diabetes. Further long-term randomized trials and basic studies are required to investigate the mechanisms.

Abstract
Diabetes is associated with the development of premature atherosclerotic disease, including coronary heart disease and acute coronary syndromes. A late consequence of this process is the development of chronic heart failure, which contributes to the increased cardiovascular (CV) morbidity and mortality associated with diabetes. Reduction of cholesterol with statins and intensive blood pressure control significantly reduce vascular events in people with diabetes. Intensive treatment of glycaemia reduces microvascular complications, especially retinopathy and nephropathy, but has only a modest effect in reducing macrovascular complications. Attention has therefore focused on individual antidiabetic drugs or drug classes to determine if these have effects in reducing CV events beyond the reduction of blood glucose. Glucagon-like peptide 1 (GLP-1) receptor agonists are a class of injected therapies that enhance the incretin effect, increasing insulin release from the pancreas and reducing glucagon production. They also have a central effect, increasing satiety, and in routine clinical use are associated with reductions in body weight. Another possibly beneficial effect of these drugs is a slight but significant reduction in systolic blood pressure. Data from cohort studies have indicated no increase in CV events with GLP-1 receptor agonists, and perhaps some reductions in CV events. The safety and possible CV benefit of these drugs is now being tested in large, multicentre, randomized, placebo-controlled trials.

Abstract
The prevalence of obesity worldwide has nearly doubled since 1980 with current estimates of 2.1 billion in 2013. Overweight and obesity lead to numerous adverse conditions including type 2 diabetes, cardiovascular disease, stroke, and certain cancers. The worldwide spread of obesity and associated comorbidities not only threatens quality of life but also presents a significant economic burden. While bariatric surgery has proven to be a viable treatment option for the morbidly obese, there is clearly a need for less invasive alternatives. Recent research has suggested that long-acting analogs of the gut hormone, glucagon-like peptide 1 (GLP-1), may have potential as an antiobesity treatment. The GLP-1 receptor agonist, liraglutide (trade name Saxenda), was recently approved by the US Food and Drug Administration as an obesity treatment option and shown in clinical trials to be effective in reducing and sustaining body weight loss. This review presents the basis for GLP-1-based therapies with a specific focus on animal and human studies examining liraglutide's effects on food intake and body weight.

Abstract
PURPOSE Treatment with liraglutide in randomized controlled trials is associated with significant reductions in glycated hemoglobin (HbA1c) and weight loss in type 2 diabetes patients. The aim of this retrospective observational study was to investigate correlations of glycemic control and weight outcomes with baseline characteristics of patients starting liraglutide in outpatient clinics in Italy. METHODS Type 2 diabetes patients were followed from baseline to 4, 8, and 12 months. Changes in glycemic parameters, weight, blood pressure, and lipids were assessed. Subanalyses were performed according to baseline characteristics. Multivariate linear and logistic regressions were used to assess correlations between glycemic efficacy, weight reduction, and liraglutide discontinuation after 12 months and baseline characteristics. FINDINGS Four hundred and eighty-one patients were included. Mean (SD) age at baseline was 57.3 (9.2) years, diabetes duration was 9.5 (6.8) years, weight was 106.7 (20.8) kg, body mass index (BMI; calculated as kg/m(2)) was 37.1 (6.6), HbA1c was 8.7% (1.3%), fasting plasma glucose was 168.5 (45.3) mg/dL; 38.2% were treated previously with insulin and 52.2% were treated with metformin alone. After 12 months, mean (SD) changes were HbA1c -1.2% (1.4%), fasting plasma glucose -28.3 (41.1) mg/dL, weight -3.5 (5.8) kg, BMI -1.3 (2.1), waist circumference -2.6 (6.7) cm (all, P < 0.001). Drop in weight and HbA1c did not differ between baseline BMI classes ≤30 or >30. Weight loss was unchanged among diabetes duration quartiles, and HbA1c reduction was significantly greater in patients with ≤4 years of diabetes duration (P = 0.01). Non-insulin-treated patients reached HbA1c ≤7% significantly more often than treated patients (44.2% vs 21.2%; odds ratio = 2.94; P < 0.001) and had significantly greater weight loss (-4.5 [8.2] kg vs -2.6 [5.4] kg; P = 0.03). Patients on metformin reached HbA1c target more frequently than others (43.1% vs 29.7%; odds ratio = 1.80; 95% CI, 1.05-3.07). Significant positive determinants for HbA1c reduction after 12 months were baseline HbA1c, age, and prior metformin monotherapy, and weight loss at 12 months was positively correlated with baseline weight, and negatively correlated with prior insulin treatment. Overall, 5.0% of patients interrupted liraglutide before the 12th month due to lack of glycemic control; they were less frequently treated with metformin only before liraglutide (29.2% vs 50.2%; P = 0.04). IMPLICATIONS Treatment with liraglutide in a real-world setting is associated with low therapy failure, good glycemic response, weight loss, and improvement in systolic blood pressure and lipid profile. The HbA1c drop did not differ among baseline BMI classes, indicating that efficacy is maintained in patients with lower BMI. The probability of reaching HbA1c ≤7% was significantly higher in patients previously treated with metformin alone and without any previous insulin. This could reinforce the hypothesis that better results with liraglutide could be achieved in patients after early metformin failure.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disease of women in reproductive age. It is characterized by anovulation and hyperandrogenism. Most often patients with PCOS have metabolic abnormalities such as dyslipidemia, insulin resistance, and glucose intolerance. It is not surprising that obesity is high prevalent in PCOS. Over 60 % of PCOS women are obese or overweight. Modulation of appetite and energy intake is essential to maintain energy balance and body weight. The gastrointestinal tract, where nutrients are digested and absorbed, plays a central role in energy homeostasis. The signals from the gastrointestinal tract arise from the stomach (ghrelin release), proximal small intestine (CCK release), and distal small intestine (GLP-1 and PYY) in response to food. These hormones are recognized as "appetite regulatory hormones." Weight loss is the key in the treatments of obese/overweight patients with PCOS. However, current non-pharmacologic management of body weight is hard to achieve. This review highlighted the gastrointestinal hormones, and discussed the potential strategies aimed at modifying hormones for treatment in PCOS.
