The potential of glucose management indicator for the estimation of glucose disposal rate in people with type 1 diabetes. Nutr Metab Cardiovasc Dis 2024; 34:2344-2352. [PMID: 39069471 DOI: 10.1016/j.numecd.2024.06.013] [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: 04/08/2024] [Revised: 06/02/2024] [Accepted: 06/17/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND AND AIMS Insulin resistance is a growing feature in type 1 diabetes (T1D). It can be quantified by calculating the estimated glucose disposal rate (eGDR) with the Epstein's formula, which includes laboratory-measured glycated hemoglobin (HbA1c). We aimed the current research to assess the agreement between the conventional eGDR formula and an alternative one (eGDR-GMI) incorporating the glucose management indicator (GMI) derived from continuous glucose monitoring (CGM). We also explored the relationship between eGDR-GMI, cardiovascular risk factors, and the prevalence of diabetes-related complications. METHODS AND RESULTS We designed a cross-sectional study that included adults with T1D. eGDR-GMI and eGDR (mg/kg/min) were calculated using GMI or HbA1c, waist circumference, and hypertensive state. Clinical data were collected from electronic medical records. The analyses encompassed 158 participants with a mean age of 39 ± 13 years. The Bland-Altman analysis showed a good agreement between eGDR-GMI and eGDR. When we divided participants in eGDR-GMI tertiles we found a higher prevalence of diabetes-related complications and a less favorable metabolic profile in the lowest eGDR-GMI tertile. The relative risk of retinopathy, nephropathy, and neuropathy significantly increased by approximately 1 unit with each decrease in eGDR-GMI, regardless of age, sex, disease duration, lipids, and smoking habit. CONCLUSIONS eGDR-GMI represents a valid and robust alternative to the eGDR to assess insulin resistance in T1D. Low eGDR-GMI is associated with diabetes complications and a less favorable metabolic profile. Incorporating the eGDR-GMI into clinical practice can enhance the characterization of T1D people and allow for a more personalized treatment approach.

Abstract
INTRODUCTION GLP-1 receptor agonists provide multiple benefits for patients with type 2 diabetes. Nonetheless, there are also several significant adverse effects associated with these agents. A thorough understanding of both therapeutic and toxicological profiles of GLP-1 receptor agonists is crucial for appropriate utilization of this medication class. A literature search of PubMed and ClinicalTrials.gov was carried out to inform discussion on the topic. AREAS COVERED This review article discusses the key advantages and disadvantages derived from the use of GLP-1 receptor agonists in the treatment of type 2 diabetes. Landmark trials which helped characterize the cardiovascular and renal benefits of GLP-1 receptor agonists are highlighted. We also discuss key studies still in progress and new formulations under investigation. EXPERT OPINION GLP-1 receptor agonists provide glycemic and complication-risk reduction benefits for individuals with type 2 diabetes. Current data suggests there is a lot of potential for further applications, even outside of type 2 diabetes management. It would be of particular interest to see the range of benefits conferred from GLP-1 receptor agonists in individuals without type 2 diabetes. Broader application of these medications could be expected given the ongoing development of new oral formulations and combination agents.

Abstract
Glucagon-like peptide-1 receptor agonist (GLP-1RA) medications have been shown to be effective in achieving optimal glucose control and reducing all-cause death, cardiovascular death, nonfatal myocardial infarction, hospitalization for heart failure, and end-stage kidney disease in individuals with type 1 (T1D) and type 2 diabetes (T2D). However, use of these medications has been associated with increased hypoglycaemia risk in patients treated with concomitant antihyperglycaemic medications. The risk is particularly high in patients with T1D due to their loss of glucagon counter-regulatory response. This article reviews the effect of GLP-1RA formulations on the development of hypoglycaemia in individuals with T1D and T2D treated with insulin therapy, discusses the benefits of continuous glucose monitoring with GLP-1RA treatment, and presents strategies for safely initiating GLP-1RA therapy in these individuals.

Liraglutide enhances insulin secretion and prolongs the remission period in adults with newly diagnosed type 1 diabetes (the NewLira study): A randomized, double-blind, placebo-controlled trial. Diabetes Obes Metab 2024. [PMID: 39192527 DOI: 10.1111/dom.15889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 07/29/2024] [Accepted: 08/05/2024] [Indexed: 08/29/2024]
Abstract
AIM To test the effect of the glucagon-like peptide-1 receptor agonist, liraglutide, on residual beta-cell function in adults with newly diagnosed type 1 diabetes. MATERIALS AND METHODS In a multicentre, double-blind, parallel-group trial, adults with newly diagnosed type 1 diabetes and stimulated C-peptide of more than 0.2 nmol/L were randomized (1:1) to 1.8-mg liraglutide (Victoza) or placebo once daily for 52 weeks with 6 weeks of follow-up with only insulin treatment. The primary endpoint was the between-group difference in C-peptide area under the curve (AUC) following a liquid mixed-meal test after 52 weeks of treatment. RESULTS Sixty-eight individuals were randomized. After 52 weeks, the 4-hour AUC C-peptide response was maintained with liraglutide, but decreased with placebo (P = .002). Six weeks after end-of-treatment, C-peptide AUCs were similar for liraglutide and placebo. The average required total daily insulin dose decreased from 0.30 to 0.23 units/kg/day with liraglutide, but increased from 0.29 to 0.43 units/kg/day in the placebo group at week 52 (P < .001). Time without the need for insulin treatment was observed in 13 versus two patients and lasted for 22 weeks (from 3 to 52 weeks) versus 6 weeks (from 4 to 8 weeks) on average for liraglutide and placebo, respectively. Patients treated with liraglutide had fewer episodes of hypoglycaemia compared with placebo-treated patients. The adverse events with liraglutide were predominantly gastrointestinal and transient. CONCLUSIONS Treatment with liraglutide improves residual beta-cell function and reduces the dose of insulin during the first year after diagnosis. Beta-cell function was similar at 6 weeks postliraglutide treatment.

Abstract
Adiposity, synonymous with obesity, is prevalent among both children and adults with type 1 diabetes in China. Recent literature underscored the patho-physiological and socioeconomic factors associated with adiposity, and consistently highlighted its impact on cardiovascular, kidney, and metabolic diseases among Chinese individuals with type 1 diabetes. Addressing and managing adiposity in individuals with type 1 diabetes are complicated and entail comprehensive approaches including lifestyle modifications, cognitive-behavioral therapy, insulin dose titration, and other diabetes treatment medications. The condition calls for coordination among policymakers, researchers, clinicians, and patients.

Abstract
Aims: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are employed extensively in the management of type 2 diabetes and obesity. However, there is a paucity of real-world data on their safety and tolerability for metabolic and nutritional adverse events in large sample populations. This study aimed to analyse the metabolic and nutritional safety signatures of different GLP-1 RAs by exploring the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). Methods: AEs data were extracted from the FDA Adverse Event Reporting System database for each GLP-1 RA from the time of its launch until the second quarter of 2023. The reported odds ratio (ROR), proportional reporting ratio (PRR), Empirical Bayesian Geometric Mean and Bayesian Confidence Propagation Neural Network were employed to identify AE signals. Results: A system organ class of metabolism and nutrition disorders was employed to filter AE reports, resulting in the identification of 10,450 reports for exenatide, 2,860 reports for liraglutide, 240 reports for albiglutide, 4,847 reports for dulaglutide, 2,905 reports for semaglutide, 1,089 reports for tirzepatide, and 13 reports for lixisenatide. Semaglutide (ROR, 3.34; 95%CI, 3.22), liraglutide (ROR, 2.78; 95%CI, 2.69), and exenatide (ROR, 2.15; 95%CI, 2.11) were associated with metabolism and nutrition disorders. The number of AE signals detected were as follows: albiglutide (n = 1), lixisenatide (n = 2), tirzepatide (n = 11), exenatide (n = 12), liraglutide (n = 16), semaglutide (n = 20), dulaglutide (n = 22). Dehydration was the most frequent AE contributing to serious outcomes for liraglutide (n = 318, 23.93%), dulaglutide (n = 434, 20.90%), semaglutide (n = 370, 25.10%) and tirzepatide (n = 70, 32.86%). The time to onset (TTO) of AE was statistically different between exenatide and the other GLP-1 RAs (p < 0.001), and the Weibull parameters for dehydration for liraglutide, dulaglutide, and semaglutide analyses all showed an early failure-type profile. Conclusion: Our study suggests that exenatide, liraglutide, and semaglutide are more susceptible to metabolic and nutritional AEs than other GLP-1 RAs. Liraglutide, dulaglutide, semaglutide, and tirzepaptide's potential to induce dehydration, necessitates special attention. Despite certain deficiencies, GLP-1 RAs have considerable potential for the treatment of eating disorders.

Abstract
Type 1 diabetes is an autoimmune condition resulting in insulin deficiency and eventual loss of pancreatic β cell function requiring lifelong insulin therapy. Since the discovery of insulin more than 100 years ago, vast advances in treatments have improved care for many people with type 1 diabetes. Ongoing research on the genetics and immunology of type 1 diabetes and on interventions to modify disease course and preserve β cell function have expanded our broad understanding of this condition. Biomarkers of type 1 diabetes are detectable months to years before development of overt disease, and three stages of diabetes are now recognized. The advent of continuous glucose monitoring and the newer automated insulin delivery systems have changed the landscape of type 1 diabetes management and are associated with improved glycated hemoglobin and decreased hypoglycemia. Adjunctive therapies such as sodium glucose cotransporter-1 inhibitors and glucagon-like peptide 1 receptor agonists may find use in management in the future. Despite these rapid advances in the field, people living in under-resourced parts of the world struggle to obtain necessities such as insulin, syringes, and blood glucose monitoring essential for managing this condition. This review covers recent developments in diagnosis and treatment and future directions in the broad field of type 1 diabetes.
