Semaglutide reduces fat accumulation in the tongue: A randomized single-blind, pilot study
2021
Abstract Aim We evaluated the effect of the latest GLP-1 RA semaglutide on tongue fat storage in obese women. Design. We conducted a randomized single-blind, pilot study. Methods Twenty-five obese women with polycystic ovary syndrome (PCOS) (33.7 ± 5.3 years, body mass index (BMI) 36.1 ± 3.9 kg/m2, mean ± SD) were randomized to semaglutide 1.0 mg or placebo for 16 weeks. We quantified tongue volume and its fat tissue and fat proportion by magnetic resonance imaging. Results Tongue fat tissue and fat proportion significantly reduced after semaglutide vs placebo (-1.94 ± 5.51 vs. + 3.12 ± 4.87 cm3, p = 0.022, and −0.02 ± 0.07 vs. 0.04 ± 0.06, p = 0.010, respectively). Correlation analysis rev…
Exploiting the Pleiotropic Antioxidant Effects of Established Drugs in Cardiovascular Disease.
2015
Cardiovascular disease is a leading cause of death and reduced quality of life worldwide. Arterial vessels are a primary target for endothelial dysfunction and atherosclerosis, which is accompanied or even driven by increased oxidative stress. Recent research in this field identified different sources of reactive oxygen and nitrogen species contributing to the pathogenesis of endothelial dysfunction. According to lessons from the past, improvement of endothelial function and prevention of cardiovascular disease by systemic, unspecific, oral antioxidant therapy are obviously too simplistic an approach. Source- and cell organelle-specific antioxidants as well as activators of intrinsic antiox…
GLP-1 receptor agonists and reduction of cardiometabolic risk: Potential underlying mechanisms
2018
Type 2 diabetes mellitus (T2DM) is a metabolic condition with an elevated impact on cardiovascular (CV) risk. The innovative therapeutic approaches for T2DM - incretin-based therapies (IBTs), including glucagon-like peptide 1 (GLP-1) receptor agonists, have become popular and more widely used in recent years. The available scientific data from clinical studies and clinical practice highlights their beyond glucose-lowering effects, which is achieved without any increase in hypoglycaemia. The former effects include reduction in body weight, lipids, blood pressure, inflammatory markers, oxidative stress, endothelial dysfunction, and subclinical atherosclerosis, thus reducing and potentially pr…
Effects of GLP-1 receptor agonists on myokine levels and pro-inflammatory cytokines in patients with type 2 diabetes mellitus.
2021
Background and aims: To evaluate the change in circulating serum irisin and interleukin-6 (IL-6), in patients with type 2 diabetes mellitus (T2DM) after 6 and 12 months of GLP-1 treatment. Methods and results: Eighty-five patients with T2DM inadequately controlled with insulin or other hypoglycaemic drugs were added to dulaglutide (N° = 44) and liraglutide (N° = 41) treatment. After 6 months of GLP-1 analogues a significant decrease in BMI (p < 0.001), waist circumference (WC) (p < 0.001), fasting blood glucose (p < 0.001), HbA1c (p < 0.001), total cholesterol (p < 0.001), LDL-cholesterol (p = 0.003), triglycerides (p = 0.017), IL-6 (p = 0.045) and a significant increase in s…
Efficacy of dulaglutide on vascular health indexes in subjects with type 2 diabetes: a randomized trial
2021
Abstract Background Recent cardiovascular outcome trials have shown significant reductions in major cardiovascular (CV) events with glucagon-like peptide (GLP)-1 receptor agonists. Additionally, adjunctive surrogates for cardiovascular risk validated by some studies include arterial stiffness and endothelial function indexes. To date, no randomized trial has addressed the possible effects of antidiabetic interventional drugs such as GLP1 agonists on endothelial and arterial stiffness indexes as surrogate markers of vascular damage. Aims We aimed to evaluate metabolic efficacy and surrogate vascular efficacy endpoints of once-weekly dulaglutide (1.5 mg) plus traditional antidiabetic treatmen…

Efficacy of GLP-1 RA Approved for Weight Management in Patients With or Without Diabetes: A Narrative Review
2022
The approval of once daily liraglutide, 3.0 mg, and once weekly semaglutide, 2.4 mg, for chronic weight management provides a novel effective strategy against obesity. The reliable models that might predict weight reducing potential at the individual level have not been identified yet. However, the coexistence of diabetes has been consistently related with less effective response than in people without this comorbidity. We aimed to review the efficacy of GLP-1 RAs approved for weight management in individuals with and without diabetes and discuss some potential mechanisms for consistently observed differences in efficacy between these two populations. The mean weight loss difference between…
Oral Semaglutide Versus Empagliflozin in Patients With Type 2 Diabetes Uncontrolled on Metformin: The PIONEER 2 Trial
2019
OBJECTIVE Efficacy and safety of the glucagon-like peptide 1 (GLP-1) analog oral semaglutide and the sodium–glucose cotransporter 2 inhibitor empagliflozin were compared in patients with type 2 diabetes uncontrolled on metformin. RESEARCH DESIGN AND METHODS Patients were randomized to once-daily open-label treatment with oral semaglutide 14 mg (n = 412) or empagliflozin 25 mg (n = 410) in a 52-week trial. Key end points were change from baseline to week 26 in HbA1c (primary) and body weight (confirmatory secondary). Two estimands addressed efficacy-related questions: treatment policy (regardless of trial product discontinuation or rescue medication) and trial product (on trial product with…
Receptor identification and physiological characterisation of glucagon-like peptide-2 in the rat heart.
2010
Abstract Background and aims The anorexigenic glucagon-like peptide (GLP)-2 is produced by intestinal L cells and released in response to food intake. It affects intestinal function involving G-protein-coupled receptors. To verify whether GLP-2 acts as a cardiac modulator in mammals, we analysed, in the rat heart, the expression of GLP-2 receptors and the myocardial and coronary responses to GLP-2. Methods and results GLP-2 receptors were detected on ventricular extracts by quantitative real-time polymerase chain reaction (Q-RT-PCR) and Western blotting. Cardiac GLP-2 effects were analysed on Langendorff perfused hearts. Intracellular GLP-2 signalling was investigated on Langendorff perfuse…
