313-OR: The Efficacy and Safety of Glucagon-Like-Peptide-1 Agonists in Patients with Familial Partial Lipodystrophy

Familial partial lipodystrophy (FPLD) syndromes are a rare group of conditions with abnormal fat distribution and deposition of fat in ectopic tissues such as liver and muscle, leading to challenging metabolic abnormalities. Glucagon-like peptide-1 receptor agonists (GLP1R-A) are used for management of other metabolic dysfunction, but their efficacy in FPLD syndromes is not known. In this retrospective EMR review, we evaluate the effect of GLP1R-A for DM management in patients with FPLD for whom there are no approved treatments in the US. We collected data from 17 patients with FPLD (age 58 ± 12; 76.47 % females) and 17 patients with type 2 DM (age 58 ± 13; 71% females) before and 6 months after starting GLP1R-A. Only cases where the sole change was the addition of GLP1R-A were included in the analyses. Reduction in weight (p=0.002), BMI (p=0.001), HbA1c (p=0.02), and fasting glucose (p=0.04) (Figure 1A-D) were observed in patients with FPLD. Only the change in triglycerides after six months of treatment was greater in patients with FPLD compared to patients with DM (p=0.02, 95%CI: 13.6 to 215.8) (Figure 1E). Overall, there were no differences in changes in other parameters, and no serious events were reported. However, we observed acute pancreatitis in two cases with FPLD with longer therapy. Our study demonstrates the relative safety and effectiveness of GLP1R-A in patients with FPLD for the first time. Disclosure S.K.Imam: None. M.C.Foss-freitas: None. R.Meral: None.

Evaluation of effects of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter-2 inhibitors on estimated glomerular filtration rate, albuminuria and weight in diabetic kidney disease: A prospective cohort study

Introduction: Albuminuria and baseline estimated glomerular filtration rate (eGFR) are the main predictors for progression of diabetic kidney disease (DKD). Objectives: The objectives of the study were to assess the effects of GLP1-RA (glucagon-like peptide-1 receptor agonists) and SGLT2i inhibitors therapy on estimated GFR, albuminuria, and weight in patients with DKD stage 3 and 4. Patients and Methods: This was a prospective cohort study of patients with stage 3 and 4 DKD over 6 months at Basra teaching hospital from November 1, 2020, to May 1, 2020. Baseline weight, UACR (urine albumin creatinine ratio), and eGFR were measured, and 6-months values were assessed between and within the group. Results: The baseline characteristics for the GLP-1 RA (GLP-1 receptor agonists) versus SGLT2i (sodium-glucose co-transporter-2 inhibitors) groups were mean ages 65 years versus 62.5 years, male (54.5% versus 50%), median weight (75 versus 80 kg), median eGFR (23.5 versus 39 ml/min/1.73 m2 ) and median UACR (925 mg/g versus 327 mg/g). In the GLP-1 RA group, after 6-months of therapy, there was 32% increase in eGFR (P<0.001), 29% decrease in UACR (P<0.001) and 4.5% decrease in weight while in the SGLT2i group, there was 4.5% decrease in eGFR (P=0.345), 34% decrease in UACR (P<0.001) and 2.8% decrease in weight (P=0.005). With cox-regression analysis, the HR for eGFR decline with SGLT2i therapy was 3.25 (95% CI: 1.1-9.97; P=0.039). Conclusion: GLP-1 RA, compared to SGLT2i therapy, caused an increase in eGFR in stages 3 and 4 CKD and caused more weight reduction but slightly less albuminuria reduction.

Renoprotective effects of GLP-1 receptor agonists and SGLT-2 inhibitors-is hemodynamics the key point?

Two novel treatments for diabetic kidney disease have emerged after decades with little progression. Both agents were developed for improved glycemic control in patients with type-2 diabetes. However, large clinical trials showed renoprotective effects beyond their ability to lower plasma glucose levels, body weight, and blood pressure. How this renal protection occurs is unknown. We will discuss their physiological effects, with special focus on the renal effects. We discuss how these drugs affect the function of the diabetic and nondiabetic kidneys to elucidate mechanisms by which the renoprotection could arise. Diabetic kidney disease affects the glomerular capillaries, which are usually protected by the renal autoregulatory mechanisms, the myogenic response, and the tubuloglomerular feedback mechanism. Animal models with reduced renal autoregulatory capacity develop chronic kidney disease. Despite different cellular targets, both drugs are suspected to affect renal hemodynamics through changes in the renal autoregulatory mechanisms. The glucagon-like peptide-1 receptor agonists (GLP-1RAs) exert a direct vasodilatory effect on the afferent arteriole (AA) positioned just before the glomerulus. Paradoxically, this effect is expected to increase glomerular capillary pressure, causing glomerular injury. In contrast, the sodium-glucose transporter-2 inhibitors (SGLT2i) are believed to activate the tubuloglomerular feedback mechanism to elicit vasoconstriction of the afferent arteriole. Because of their opposing effects on the renal afferent arterioles, it appears unlikely that their renoprotective effects can be explained by common effects of renal hemodynamics, but both drugs appear to add protection to the kidney beyond what can be obtained with classical treatment targeted at lowering blood glucose levels and blood pressure.

Time-dependent effect of GLP-1 receptor agonists on cardiovascular benefits: a real-world study

BackgroundGlucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown cardiovascular benefits in cardiovascular outcome trials in type 2 diabetes mellitus. However, the most convincing evidence was obtained in subjects with established cardiovascular (CV) disease. We analyzed the determinants of GLP-1 RA-mediated CV protection in a real-world population of persons with type 2 diabetes with and without a history of CV events with long-term follow-up.MethodsRetrospective cohort study of 550 individuals with type 2 diabetes (395 in primary CV prevention, 155 in secondary CV prevention), followed at a single center after the first prescription of a GLP-1 RA between 2009 and 2019. CV and metabolic outcomes were assessed.ResultsMedian duration of follow-up was 5.0 years (0.25–10.8) in primary prevention and 3.6 years (0–10.3) in secondary prevention, with a median duration of treatment of 3.2 years (0–10.8) and 2.5 years (0–10.3) respectively. In the multivariable Cox regression model considering GLP-1 RA treatment as a time-dependent covariate, in the primary prevention group, changes in BMI and glycated hemoglobin did not have an impact on MACE risk, while age at the time of GLP-1 initiation (HR 1.08, 95% CI 1.03–1.14, p = 0.001) and GLP-1 RA cessation by time (HR 3.40, 95% CI 1.82–6.32, p < 0.001) increased the risk of MACE. Regarding the secondary prevention group, only GLP-1 RA cessation by time (HR 2.71, 95% CI 1.46–5.01, p = 0.002) increased the risk of MACE. With respect to those who withdrew treatment, subjects who continued the GLP-1 RA had significantly greater weight loss and lower glycated hemoglobin levels during follow-up.ConclusionsIn this real-world type 2 diabetes population, discontinuation of GLP-1 RA treatment was associated to a higher risk of major cardiovascular events, in both subjects with and without a history of CV events.

Comparison of glucagon-like peptide-1 receptor agonists and thiazolidinediones on treating nonalcoholic fatty liver disease: A network meta-analysis.

Previous studies have revealed that glucagon-like peptide-1 receptor agonist (GLP-1RA) and thiazolidinedione (TZD) can improve nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). However, comprehensive research comparing the effects of GLP-1RA and TZD is limited. Thus, this study aimed to compare the effects of GLP-1RA and TZD on NAFLD or NASH through a network meta-analysis. The PubMed, Embase, Web of Science, and Scopus databases were searched for randomized controlled trials (RCTs) that explored the efficacy of GLP-1RAs or TZDs in adult patients with NAFLD or NASH. The outcomes were liver biopsy-based (NAFLD activity score [NAS], fibrosis stage, and NASH resolution), noninvasive technique-based (liver fat content on proton magnetic resonance spectroscopy [1H-MRS] and controlled attenuation parameter [CAP]), biological, and anthropometric indicators. A random effects model was used to calculate the mean difference (MD) and relative risk with 95% confidence interval (CI). Twenty-five RCTs with 2,237 overweight or obese patients were included. GLP-1RA was significantly superior in reducing liver fat content evaluated using 1H-MRS (MD -2.42, 95% CI -3.84 to -1.00), body mass index (MD -1.60, 95% CI -2.41 to -0.80), and waist circumference (MD -4.89, 95% CI -8.17 to -1.61) than TZD. In liver biopsy-based evaluation and liver fat content assessment using CAP, GLP-1RA tended to surpass TZD, albeit not significantly. Sensitivity analysis showed consistent results with the main results. Compared with TZD, GLP-1RA had better effects on liver fat content, body mass index, and waist circumference in overweight or obese patients with NAFLD or NASH.

Glucagon-Like Peptide-1 Receptor Agonist Protects Against Diabetic Cardiomyopathy by Modulating microRNA-29b-3p/SLMAP.

Our aims were to investigate the pathogenesis of diabetic cardiomyopathy (DCM) and to explore the protective effect of glucagon-like peptide-1 receptor agonist (GLP-1RA) on DCM. After 12 weeks of treatment with exenatide-loaded microspheres, a long-acting GLP-1RA, in DCM mice, cardiac structure and function were evaluated by plasma B-type natriuretic peptide (BNP), echocardiography, H&E, oil red and Sirius staining. The expression of glucagon-like peptide-1 receptor in mouse heart tissue was determined by immunofluorescence staining. The label-free proteomic analysis of cardiac proteins was conducted among control, DCM and DM+GLP-1RA groups. Then, quantitative real-time PCR, Western blotting and dual-luciferase reporter assay were performed to verify the regulation of target protein by the upstream microRNA (miRNA). GLP-1RA treatment obviously improved serum BNP, myocardial fibrosis, lipid deposition of the myocardium and echocardiography parameters in DCM mice. Sarcolemmal membrane-associated protein (SLMAP) was one of 61 differentially expressed cardiac proteins found in three groups by proteomic analysis. Up-regulation of microRNA-29b-3p (miR-29b-3p) and down-regulation of SLMAP were found in the ventricular myocardium of GLP-1RA-treated DCM mice. SLMAP was a target of miR-29b-3p, while GLP-1RA regulated SLMAP expression through miR-29b-3p. Furthermore, inhibition of glucagon-like peptide-1 receptor (GLP-1R) in cardiomyocytes reversed the effects of GLP-1RA on miR-29b/SLMAP. SLMAP may play roles in the pathogenesis of DCM and may be a target of GLP-1RA in protecting against DCM. After binding to myocardial GLP-1R, GLP-1RA can regulate the expression of myocardial SLMAP through miR-29b-3p.

Glucagon-like peptide 1 receptor agonists in patients with type 2 diabetes with and without chronic heart failure: A meta-analysis of randomized placebo-controlled outcome trials.

Glucagon-like peptide 1 receptor agonists (GLP1-RA) reduce atherosclerotic events in patients with type 2 diabetes (T2D) and a high cardiovascular risk. The effect of GLP1-RA to reduce heart failure (HF) has been inconsistent across T2D trials, and individual trials were underpowered to assess the effect of GLP1-RA according to HF history. In this meta-analysis we aim to assess the effect of GLP1-RA in patients with and without HF history in stable ambulatory patients with T2D. Random-effects meta-analysis of placebo-controlled trials. The hazard ratio (HR) and 95% confidence intervals (95% CI) were extracted from the treatment effect estimates of HF subgroup analyses reported in each individual study. The primary outcome was a composite of HF hospitalization or cardiovascular death. In total, 54 092 patients with T2D from seven randomized controlled trials were included, of whom 8460 (16%) had HF history. Compared with placebo, GLP1-RA did not reduce the composite of HF hospitalization or cardiovascular death in patients with HF history: HR 0.96, 95% CI: 0.84-1.08, but reduced this outcome in patients without HF history: HR 0.84, 95% CI: 0.76-0.92. GLP1-RA did not reduce all-cause death in patients with HF history: HR 0.98, 95% CI: 0.86-1.11, but reduced mortality in patients without HF history: HR 0.85, 95% CI: 0.79-0.92. GLP1-RA reduced atherosclerotic events regardless of HF history: HR 0.85, 95% CI: 0.75-0.97 with HF, and HR 0.88, 95% CI: 0.83-0.93 without HF. Treatment with GLP1-RA did not reduce HF hospitalizations and mortality in patients with concomitant T2D and HF, but may prevent new-onset HF and mortality in patients with T2D without HF. The reduction of atherosclerotic events with GLP1-RA was not influenced by HF history status.

GLP-1 receptor agonists for the treatment of obesity: Role as a promising approach.

Obesity is a complex disease characterized by excessive fat accumulation which is caused by genetic, environmental and other factors. In recent years, there has been an increase in the morbidity, disability rate,and mortality due to obesity, making it great threat to people's health and lives, and increasing public health care expenses. Evidence from previous studies show that weight loss can significantly reduce the risk of obesity-related complications and chronic diseases. Diet control, moderate exercise, behavior modification programs, bariatric surgery and prescription drug treatment are the major interventions used to help people lose weight. Among them, anti-obesity drugs have high compliance rates and cause noticeable short-term effects in reducing obese levels. However, given the safety or effectiveness concerns of anti-obesity drugs, many of the currently used drugs have limited clinical use. Glucagon-like peptide-1 receptor (GLP-1R) agonists are a group of drugs that targets incretin hormone action, and its receptors are widely distributed in nerves, islets, heart, lung, skin, and other organs. Several animal experiments and clinical trials have demonstrated that GLP-1R agonists are more effective in treating or preventing obesity. Therefore, GLP-1R agonists are promising agents for the treatment of obese individuals. This review describes evidence from previous research on the effects of GLP-1R agonists on obesity. We anticipate that this review will generate data that will help biomedical researchers or clinical workers develop obesity treatments based on GLP-1R agonists.

GLP-1 analogues in the treatment of obesity and non-alcoholic fatty liver disease

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.

Acute Cholesterol-Lowering Effect of Exendin-4 in Ldlr-/- and C57BL/6J Mice.

We previously reported that glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduced serum low-density lipoprotein cholesterol (LDL-C) levels in patients with type 2 diabetes mellitus receiving statins, which increased LDL receptor (LDLR) expression. Nevertheless, it remains unclear how much LDLR expression contributes to the LDL-C-lowering effect of GLP-1RAs. We examined the effect of a GLP-1RA, namely, exendin-4, on serum LDL-C levels and its mechanism in Ldlr-/- and C57BL/6J mice. Ten-week-old Ldlr-/- and C57BL/6J mice received exendin-4 or saline for 5 days, and serum lipid profiles and hepatic lipid levels were examined. Cholesterol metabolism-related gene expression and protein levels in the liver and ileum and the fecal bile acid (BA) composition were also examined. Exendin-4 treatment significantly decreased serum very-low-density lipoprotein cholesterol (VLDL-C) and LDL-C levels and mature hepatic SREBP2 levels and increased hepatic Insig1/2 mRNA expression in both mouse strains. In Ldlr-/- mice, exendin-4 treatment also significantly decreased hepatic cholesterol levels and fecal BA excretion, decreased hepatic Cyp7a1 mRNA expression, and increased small intestinal Fgf15 mRNA expression. In C57BL/6J mice, exendin-4 treatment significantly decreased small intestinal NPC1L1 levels. Our findings demonstrate that exendin-4 treatment decreased serum VLDL-C and LDL-C levels in a manner that was independent of LDLR. Exendin-4 treatment might decrease serum cholesterol levels by lowering hepatic SREBP2 levels and cholesterol absorption in Ldlr-/- and C57BL/6J mice. Exendin-4 treatment might decrease cholesterol absorption by different mechanisms in Ldlr-/- and C57BL/6J mice.

Design and rationale for the SIB trial: a randomized parallel comparison of semaglutide versus placebo on intestinal barrier function in type 2 diabetes mellitus

Objective: To describe the rationale and design of the SIB trial, an interventional clinical trial testing the hypothesis that subcutaneous (s.c.) once-weekly semaglutide can improve intestinal permeability and reduce systemic inflammation in participants with type 2 diabetes (T2D) and obesity. Methods: SIB (NCT04979130) is an investigator-initiated, single-center randomized, double-blinded, placebo-controlled clinical study being conducted at the University of Colorado Anschutz Medical Campus. The primary objective of this novel trial is to test the hypothesis that subcutaneous (s.c.) once-weekly semaglutide could improve intestinal permeability and reduce systemic inflammation in participants with T2D and obesity. Eligible participants had a diagnosis of type 2 diabetes, elevated body mass index, and evidence of systemic inflammation. Participants were randomized 1:1 to s.c. semaglutide or placebo. Participants were assessed for intestinal permeability and markers of inflammation at baseline, mid-study, and at the end of the study. Efficacy assessments were based on the analysis of the following: lactulose:mannitol ratio test, serum lipopolysaccharide-binding protein (LBP), fecal calprotectin, inflammatory biomarkers (IL-6, TNF, IL-1, IL-8, hs-CRP), and HbA1c. All participants who enrolled in the trial provided written informed consent after having received written and oral information on the trial. The risks of semaglutide use were minimized by administration according to FDA-labeled use and close monitoring for adverse events. Discussion: SIB is the first study to examine the effects of GLP-1 receptor agonists on intestinal permeability in humans and will provide important data on their impact on systemic inflammation and intestinal permeability in the setting of T2D and obesity.

769 EFFECT OF GLUCOSE LOWERING AGENTS ON CARDIAC AUTONOMIC FUNCTION AND STRUCTURE IN TYPE 2 DIABETES MELLITUS

Effects of novel glucose-lowering agents on cardiac autonomic function and structure in type 2 diabetes Ilaria Cavallari, Ernesto Maddaloni, Francesco Veneziano, Carla Indennidate, Maria Valeria Giaccari, Dario Tuccinardi, Silvia Pieralice, Nicola Napoli, Raffaella Buzzetti, Francesco Grigioni Background Novel glucose-lowering agents, such as sodium glucose co-transporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists, have the potential to reduce major adverse cardiovascular events among people with type 2 diabetes. However, mechanisms behind their cardiovascular protection and the implications of positive chronotropic effects of GLP-1 receptor agonists are not fully understood. Purpose To elucidate and compare the effects of novel glucose-lowering agents on cardiac autonomic function and structure. Methods This prospective observational study included subjects with type 2 diabetes and either a history of established cardiovascular disease or multiple risk factors and early initiation (within 2 weeks) of a SGLT-2 inhibitor or a GLP-1 receptor agonist on top of standard of care. Patients were followed for a median of 2 months. As per study protocol, background medical therapy should have remained stable for the entire duration of the study. Cardiac autonomic reflex tests (heart rate response to a deep breathing and to standing) and echocardiography were performed in all patients at baseline and at the end of follow-up. Endpoints were changes from baseline of E/I ratio, 30:15 ratio and indices of cardiac structure and function. Results A total of 37 patients completed follow-up, of whom 20 were on SGLT-2 inhibitors and 17 on GLP-1 receptor agonists. Mean age was 69 years, mean disease duration was 14 years and mean HbA1c value was 7.5%. Cardiac autonomic dysfunction, defined as at least an abnormal test, was found in 19% of patients (n=7). At a median follow-up of 2 months, there were no differences from baseline in heart rate response to a deep breathing test (p=0.92) and to standing (p=0.86). No differences were found when patients were stratified according to drug class. Among echocardiographic parameters, significant reductions of left ventricular mass (300.5±73.3 vs 280.4±68.3 g/m2, p=0.048) and left atrial volume (61.3±29.4 vs 54.7±18.0 ml, p=0.034) were found with no interaction by drug class. Left ventricular end-diastolic and systolic volumes, ejection fraction, filling pressures and pulmonary artery pressure did not substantially change. Conclusions In a population of patients with type 2 diabetes, short-term treatment with novel glucose-lowering agents significantly reduced left ventricular mass and left atrial volume but did not affect cardiac autonomic function.

Pharmacogenomics of GLP-1 receptor agonists: a genome-wide analysis of observational data and large randomised controlled trials

In the treatment of type 2 diabetes, GLP-1 receptor agonists lower blood glucose concentrations, body weight, and have cardiovascular benefits. The efficacy and side effects of GLP-1 receptor agonists vary between people. Human pharmacogenomic studies of this inter-individual variation can provide both biological insight into drug action and provide biomarkers to inform clinical decision making. We therefore aimed to identify genetic variants associated with glycaemic response to GLP-1 receptor agonist treatment. In this genome-wide analysis we included adults (aged ≥18 years) with type 2 diabetes treated with GLP-1 receptor agonists with baseline HbA1c of 7% or more (53 mmol/mol) from four prospective observational cohorts (DIRECT, PRIBA, PROMASTER, and GoDARTS) and two randomised clinical trials (HARMONY phase 3 and AWARD). The primary endpoint was HbA1c reduction at 6 months after starting GLP-1 receptor agonists. We evaluated variants in GLP1R, then did a genome-wide association study and gene-based burden tests. 4571 adults were included in our analysis, of these, 3339 (73%) were White European, 449 (10%) Hispanic, 312 (7%) American Indian or Alaskan Native, and 471 (10%) were other, and around 2140 (47%) of the participants were women. Variation in HbA1c reduction with GLP-1 receptor agonists treatment was associated with rs6923761G→A (Gly168Ser) in the GLP1R (0·08% [95% CI 0·04-0·12] or 0·9 mmol/mol lower reduction in HbA1c per serine, p=6·0 × 10-5) and low frequency variants in ARRB1 (optimal sequence kernel association test p=6·7 × 10-8), largely driven by rs140226575G→A (Thr370Met; 0·25% [SE 0·06] or 2·7 mmol/mol [SE 0·7] greater HbA1c reduction per methionine, p=5·2 × 10-6). A similar effect size for the ARRB1 Thr370Met was seen in Hispanic and American Indian or Alaska Native populations who have a higher frequency of this variant (6-11%) than in White European populations. Combining these two genes identified 4% of the population who had a 30% greater reduction in HbA1c than the 9% of the population with the worse response. This genome-wide pharmacogenomic study of GLP-1 receptor agonists provides novel biological and clinical insights. Clinically, when genotype is routinely available at the point of prescribing, individuals with ARRB1 variants might benefit from earlier initiation of GLP-1 receptor agonists.

#1302161: Mechanism Behind GLP1RA-Induced Refractory Tachycardia: A Case and Literature Review

Sinus tachycardia is a known adverse effect of GLP1 receptor agonists (GLP1 RA). We present a case of a patient who developed symptomatic tachycardia resistant to beta-blockers administration, after starting liraglutide for type 2 diabetes mellitus (T2DM).

The mechanism and efficacy of GLP-1 receptor agonists in the treatment of Alzheimer's disease.

Since type 2 diabetes mellitus (T2DM) is a risk factor for Alzheimer's disease (AD) and both have the same pathogenesis (e.g., insulin resistance), drugs used to treat T2DM have been gradually found to reduce the progression of AD in AD models. Of these drugs, glucagon-like peptide 1 receptor (GLP-1R) agonists are more effective and have fewer side effects. GLP-1R agonists have reducing neuroinflammation and oxidative stress, neurotrophic effects, decreasing Aβ deposition and tau hyperphosphorylation in AD models, which may be a potential drug for the treatment of AD. However, this needs to be verified by further clinical trials. This study aims to summarize the current information on the mechanisms and effects of GLP-1R agonists in AD.
