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.

Abstract
Diabetic ketoacidosis is a serious diabetes-related consequence that occurs in type 1 diabetes and less commonly in type 2 diabetes and is a major cause of death. It results from the metabolic consequences due to a lack of insulin secretion or impaired insulin activity in diabetes leading to dysregulated pathophysiologic pathways resulting in excessive ketone body formation. While ketone bodies are physiologic molecules, their high levels reduce the physiological pH of the blood and induce ketoacidosis, leading to increasing metabolic dysfunction. Glucagon-like peptide-1 (GLP-1) mimetics are a class of recently developed diabetes therapy that do not lead to hypoglycemic, but some reports have suggested a relationship between GLP-1 mimetics and ketogenesis. To clarify the possible interactions between GLP-1 mimetics and ketogenesis in diabetes, this review was undertaken to collate and interpret the literature.

Abstract
Objectives: Sodium-glucose transporter-2 inhibitors (SGLT2i) are commonly used for the treatment of Type 2 Diabetes Mellitus, offering additional benefits in non-diabetic patients with conditions such as chronic kidney disease and heart failure. However, SGLT2i have been associated with an increased risk of euglycemic diabetic ketoacidosis (DKA). This case series describes three cases of patients who developed euglycemic DKA while taking SGLT2i. Key Findings: Each of the three patients with euglycemic DKA were taking SGLT2i for the treatment of diabetes and all had additional risk factors for the development of DKA. These factors included reduced oral intake, major acute illness, chronic pancreatitis, and a history of previous DKA episodes. Unfortunately, the absence of hallmark symptoms like hyperglycemia, polyuria, and polydipsia led to delayed diagnosis of euglycemic DKA in two of the three patients. Conclusion: Early recognition of risk factors and a high level of suspicion are critical in identifying euglycemic DKA in patients taking SGLT2i. Healthcare providers should conduct thorough medication reconciliation upon admission and closely monitor patients for concurrent issues, especially in cases of minimal oral intake, acute illnesses, and chronic pancreatitis. Prompt diagnosis and management of euglycemic DKA can significantly improve patient outcomes.

Abstract
The current study focuses on the importance of Protein-Protein Interactions (PPIs) in biological processes and the potential of targeting PPIs as a new treatment strategy for diseases. Specifically, the study explores the cross-links of PPIs network associated with obesity, type 1 diabetes mellitus (T1DM), and cardiac disease (CD), which is an unexplored area of research. The research aimed to understand the role of highly connected proteins in the network and their potential as drug targets. The methodology for this research involves retrieving genes from the NCBI online gene database, intersecting genes among three diseases (type 1 diabetes, obesity, and cardiovascular) using Interactivenn, determining suitable drug molecules using NetworkAnalyst, and performing various bioinformatics analyses such as Generic Protein-Protein Interactions, topological properties analysis, function enrichment analysis in terms of GO, and Kyoto Encyclopedia of Genes and Genomes (KEGG), gene co-expression network, and protein drug as well as protein chemical interaction network. The study focuses on human subjects. The results of this study identified 12 genes [VEGFA (Vascular Endothelial Growth Factor A), IL6 (Interleukin 6), MTHFR (Methylenetetrahydrofolate reductase), NPPB (Natriuretic Peptide B), RAC1 (Rac Family Small GTPase 1), LMNA (Lamin A/C), UGT1A1 (UDP-glucuronosyltransferase family 1 membrane A1), RETN (Resistin), GCG (Glucagon), NPPA (Natriuretic Peptide A), RYR2 (Ryanodine receptor 2), and PRKAG2 (Protein Kinase AMP-Activated Non-Catalytic Subunit Gamma 2)] that were shared across the three diseases and could be used as key proteins for protein-drug/chemical interaction. Additionally, the study provides an in-depth understanding of the complex molecular and biological relationships between the three diseases and the cellular mechanisms that lead to their development. Potentially significant implications for the therapy and management of various disorders are highlighted by the findings of this study by improving treatment efficacy, simplifying treatment regimens, cost-effectiveness, better understanding of the underlying mechanism of these diseases, early diagnosis, and introducing personalized medicine. In conclusion, the current study provides new insights into the cross-links of PPIs network associated with obesity, T1DM, and CD, and highlights the potential of targeting PPIs as a new treatment strategy for these prevalent diseases.

Abstract
Background/Objective Allergic reactions to insulin have decreased significantly since the introduction of human insulin preparation, but up to 2.4% of insulin-treated patients can still be affected. Rituximab is a monoclonal antibody against the surface antigen CD20 on B lymphocytes, and it is largely used to treat lymphoproliferative and rheumatological conditions. In a very few published case reports, rituximab has been used as an investigational drug to treat severe insulin allergy refractory to conventional therapy. Here, we present an unusual case of a 40-year-old woman with T1DM and severe insulin allergy that was successfully treated with rituximab. Case Report The patient was diagnosed with T1DM at age 37. Three years later, skin reactions developed at insulin administration sites. These consisted of pruritic and painful erythema and wheals that appeared within 1 to 4 h of insulin administration, followed by induration, subcutaneous nodules, and surrounding lipodystrophy that lasted several days with spontaneous resolution in 1 to 2 weeks. Extensive immunologic evaluation suggested the reaction was related to insulin allergy. Skin biopsy revealed sublobular panniculitis. After failed conventional treatment with antihistamines, glucocorticoid, and various insulins, rituximab infusion as an investigational approach was initiated. This was very successful, leading to prolonged remission of her insulin allergy. Discussion First-line management of insulin allergy should focus on second-generation antihistamines and switching insulin preparation. In refractory cases, systemic immunotherapy with rituximab can be a viable option. Conclusion Practitioners should be aware that in patients with insulin allergy who fail conventional treatment, immunotherapy with rituximab can be a viable option.

Bromodomain Protein Inhibition Protects β-Cells from Cytokine-Induced Death and Dysfunction via Antagonism of NF-κB Pathway. Cells 2024; 13:1108.

Abstract
Cytokine-induced β-cell apoptosis is a major pathogenic mechanism in type 1 diabetes (T1D). Despite significant advances in understanding its underlying mechanisms, few drugs have been translated to protect β-cells in T1D. Epigenetic modulators such as bromodomain-containing BET (bromo- and extra-terminal) proteins are important regulators of immune responses. Pre-clinical studies have demonstrated a protective effect of BET inhibitors in an NOD (non-obese diabetes) mouse model of T1D. However, the effect of BET protein inhibition on β-cell function in response to cytokines is unknown. Here, we demonstrate that I-BET, a BET protein inhibitor, protected β-cells from cytokine-induced dysfunction and death. In vivo administration of I-BET to mice exposed to low-dose STZ (streptozotocin), a model of T1D, significantly reduced β-cell apoptosis, suggesting a cytoprotective function. Mechanistically, I-BET treatment inhibited cytokine-induced NF-kB signaling and enhanced FOXO1-mediated anti-oxidant response in β-cells. RNA-Seq analysis revealed that I-BET treatment also suppressed pathways involved in apoptosis while maintaining the expression of genes critical for β-cell function, such as Pdx1 and Ins1. Taken together, this study demonstrates that I-BET is effective in protecting β-cells from cytokine-induced dysfunction and apoptosis, and targeting BET proteins could have potential therapeutic value in preserving β-cell functional mass in T1D.

Abstract
Since 1980, the cumulative effort of scientists and health-care stakeholders has advanced the prerequisites to address metabolic dysfunction-associated steatotic liver disease (MASLD), a prevalent chronic non-communicable liver disease. This effort has led to, among others, the approval of the first drug specific for metabolic dysfunction-associated steatohepatitis (MASH; formerly known as nonalcoholic steatohepatitis). Despite substantial progress, MASLD is still a leading cause of advanced chronic liver disease, including primary liver cancer. This Perspective contextualizes the nomenclature change from nonalcoholic fatty liver disease to MASLD and proposes important considerations to accelerate further progress in the field, optimize patient-centric multidisciplinary care pathways, advance pharmacological, behavioural and diagnostic research, and address health disparities. Key regulatory and other steps necessary to optimize the approval and access to upcoming additional pharmacological therapeutic agents for MASH are also outlined. We conclude by calling for increased education and awareness, enhanced health system preparedness, and concerted action by policy-makers to further the public health and policy agenda to achieve at least parity with other non-communicable diseases and to aid in growing the community of practice to reduce the human and economic burden and end the public health threat of MASLD and MASH by 2030.

Abstract
Many individuals with type 1 diabetes (T1D) do not achieve their management goals. The patient perspective on unmet needs in T1D may guide the role of adjunctive therapies, including glucagon like peptide-1 receptor agonists (GLP-1RAs). A quantitative online survey (n = 133) assessed (1) self-reported demographic and management data, (2) management priorities, satisfaction, and willingness to use adjunctive therapies and (3) conducted a risk-benefit analysis using three masked drug profiles (1.8 mg vs 0.6 mg liraglutide vs placebo). A subgroup of respondents (n = 20) participated in semi-structured interviews to extend upon survey insights. Needs were unmet by current treatment in 28% of surveyed individuals. The greatest unmet needs included (1) glycemia, (2) management-related fatigue, and (3) weight management. Most respondents (94%) indicated that they would use adjunctive therapies. The preferred administration route was daily tablets (66%) followed by weekly injections (32%). Metabolic improvements were most valued (reduction in hypoglycemia, hyperglycemia). Most respondents (94%) preferred the liraglutide risk-benefit profile (1.8 mg, then 0.6 mg) over placebo. Individuals with T1D self-report many unmet needs. While not currently approved in T1D, GLP-1RA properties align with many management priorities reported by individuals with T1D.

Abstract
BACKGROUND Once weekly Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RA) have been shown to improve glycemic outcomes and cause significant weight loss. However, 9% to 27% of individuals have little or no response to these drugs. In this article, we investigated the efficacy of GLP-1 RA therapy among adults with type 1 diabetes and obesity likely related to genetic mutations compared with obesity likely unrelated to genetic mutations. METHODS In this retrospective study, we compared body weight and glycated hemoglobin (HbA1c) change with the use of GLP-1 RA therapy (including a dual agonist, Tirzepatide) over six months among adults with type 1 diabetes and obesity likely (n = 11, median age 39.5 years with a median BMI of 43.0 kg/m2) versus unlikely related to genetic mutation(s) (n = 15, median age 45.8 years with a median BMI of 38.7 kg/m2). RESULTS Six months of GLP-1 RA treatment resulted in a numerically lower reduction of weight (-5.75 ± 9.46 kg vs -8.65 ± 9.36 kg, P = .44) and HbA1c (-0.28 ± 0.96% vs -0.43 ± 0.57%, P = .64) among individuals with obesity likely versus unlikely related to a genetic mutation(s), respectively. Fewer individuals with genetic obesity met goal weight loss ≥5% or HbA1c decrease ≥0.4% than did individuals with obesity unlikely related to a genetic cause (36.4% vs 80.0%, P = .04). CONCLUSIONS The weight loss and glycemic lowering effects of GLP-1 RA therapy may be decreased in people with type 1 diabetes and obesity likely related to genetic causes. Further research is needed to understand GLP-1 RA mechanisms via energy regulating genes.

Abstract
Obesity, a chronic low-grade inflammatory disease represented by multifactorial metabolic dysfunctions, is a significant global health threat for adults and children. The once-held belief that type 1 diabetes is a disease of people who are lean no longer holds. The mounting epidemiological data now establishes the connection between type 1 diabetes and the subsequent development of obesity, or vice versa. Beyond the consequences of the influx of an obesogenic environment, type 1 diabetes-specific biopsychosocial burden further exacerbates obesity. In the course of obesity management discussions, recurring challenges surfaced. The interplay between weight gain and escalating insulin dependence creates a vicious cycle from which patients struggle to break free. In the absence of weight management guidelines and regulatory approval for this population, healthcare professionals must navigate the delicate balance between benefits and risks. The gravity of this circumstance highlights the importance of bringing these topics to the forefront. In this Review, we discuss the changing trends and the biopsychosocial aspects of the intersection between type 1 diabetes and obesity. We highlight the evidence supporting the therapeutic means (i.e., exercise therapy, nutritional therapy, adjunct pharmacotherapy, and bariatric surgery) and directions for establishing a more robust and safer evidence-based approach.

Abstract
BACKGROUND Tirzepatide is approved by the United States Food and Drug Administration (FDA) for the management of type 2 diabetes. The efficacy and safety of this drug have not been studied in people with type 1 diabetes (T1D). METHODS In this single-center, retrospective, observational study, hemoglobin A1C (HbA1c), weight, body mass index (BMI), and continuous glucose monitoring (CGM) data were collected from electronic health records of adults with T1D at initiation of tirzepatide and at subsequent clinic visits over 8 months. Primary outcomes were reduction in HbA1c and percent change in body weight and secondary outcomes were change in CGM metrics and BMI over 8 months from baseline. RESULTS The mean (±SD) age of the 26 adults (54% female) with T1D was 42 ± 8 years with a mean BMI of 36.7 ± 5.3 kg/m2. There was significant reduction in HbA1c by 0.45% at 3 months and 0.59% at 8 months, and a significant reduction in body weight by 3.4%, 10.5%, and 10.1% at 3, 6, and 8 months after starting tirzepatide. Time in target range (TIR = 70-180 mg/dL) and time in tight target range (TITR = 70-140 mg/dL) increased (+12.6%, P = .002; +10.7%, P = .0016, respectively) and time above range (TAR >180 mg/dL) decreased (-12.6%, P = .002) at 3 months, and these changes were sustained over 8 months. The drug was relatively safe and well tolerated with only 2 patients discontinuing the medication. CONCLUSIONS Tirzepatide significantly reduced HbA1c and body weight in adults with T1D. A randomized controlled trial is needed to establish efficacy and safety of this drug in T1D.

Abstract
PURPOSE OF REVIEW Obesity is an epidemic in the United States with serious concomitant co-morbid conditions; people living with type 1 diabetes mellitus (T1D) are not immune to the risk either. Weight gain in T1D is likely multifactorial, due to genetic, environmental and treatment-related factors. FDA-approved and other adjunctive weight loss therapies may benefit people living with T1D but there are risks to consider when providing recommendations or prescribing medications. RECENT FINDINGS We performed a PubMed search of studies assessing clinical outcomes of both approved and off-label medications used in the treatment of type 1 diabetes. Search terms included 'type 1 diabetes, obesity' and the following: (1) metformin, (2) pramlintide, (3) glucagon-like peptide-1 (GLP-1) receptor agonists, (4) dual GLP-1 and gastric inhibitory polypeptide (GIP) agonists, (5) sodium-glucose cotransporter-2 (SGLT-2) inhibitors, (6) surgical treatment of obesity, (7) insulin pump, (8) insulin, (9) medical nutrition therapy, (10) diabetes self-management education, (11) exercise, (12) naltrexone-buproprion, (13) orlistat, and (14) phentermine-topiramate. SUMMARY Weight loss treatments provide a wide-range of benefits in reducing both morbidity and mortality in those who are obese. Treatments also have varying adverse effect profiles which may impact T1D treatment. In this review, we aim to summarize study outcomes in people with T1D, including risks and benefits, of on- and off-label weight loss treatments.

Abstract
OBJECTIVE To assess real-world safety and effectiveness of dapagliflozin in people living with type 1 diabetes mellitus (T1DM). METHODS We conducted a multicenter retrospective study in Spain including data from 250 people living with T1DM receiving dapagliflozin as add-on therapy to insulin (80.8 % on-label use). The number of diabetic ketoacidosis (DKA) events was calculated over a 12-month follow-up (primary outcome). Changes in body weight, HbA1c, total daily insulin dose, and continuous glucose monitoring (CGM) metrics from baseline (at dapagliflozin prescription) to 12 months were also evaluated. RESULTS A total of five DKA events (2.4 % [95 % CI 0.3;4.5] were reported in patients with a 12-month follow-up, n = 207): two events related to insulin pump malfunction, two events related to concomitant illnesses, and one event related to insulin dose omission. DKA events were more frequent among insulin pump users than among participants on multiple daily injections (7.7 % versus 1.2 %). Four of the reported DKA events occurred within the first six months after initiation of dapagliflozin. No deaths or persistent sequelae due to DKA were reported. No severe hypoglycemia episodes were reported. Significant reductions in mean body weight (-3.3 kg), HbA1c (-0.6 %), and total daily insulin dose (-8.6 %), P < 0.001, were observed 12 months after dapagliflozin prescription. Significant improvements in TIR (+9.3 %), TAR (-7.2 %), TBR (-2.5 %), and coefficient of variation (-5.1 %), P < 0.001, were also observed in the subgroup of patients with available CGM data. Finally, an improvement in urinary albumin-to-creatinine ratio (UACR) was found among participants with UACR ≥ 30 mg/g at baseline (median decrease of 99 mg/g in UACR, P = 0.001). CONCLUSION The use of dapagliflozin in people living with T1DM has an appropriate safety profile after careful selection of participants and implementation of strategies to reduce the risk of DKA (i.e., prescribed according to the recommendations of the European Medicines Agency), and also leads to clinical improvements in this population.

[PMID: 38158765 DOI: 10.1111/imj.16312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/29/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Many people living with type 1 diabetes (type 1 diabetes mellitus (T1DM)) do not meet glycaemic targets. Adjunctive therapies have both risks and metabolic benefits and may have a role in selected patients. AIM To review the prescribing patterns of adjunctive therapy for the treatment of T1DM diabetes in Australia. METHODS We conducted an online survey of Australian endocrinologists and endocrinology registrars. We surveyed the frequency of, motivations and concerns regarding the prescription of metformin, dipeptidyl peptidase-4 (DPP-IV) inhibitors, sodium-glucose transport protein 2 (SGLT-2) inhibitors and glucagon-like peptide 1 receptor agonist (GLP1RA) in T1DM. RESULTS Fifty-two practitioners participated. Most respondents (94%) had prescribed adjuncts for the treatment of T1DM in some form. Weight (89%), large insulin doses (73%), glycaemic variability (52%), high HbA1c (48%) and the presence of cardiovascular disease (48%) were the most common factors determining the use of adjuncts. The most commonly prescribed adjuncts were metformin (94%) and SGLT-2 inhibitors (65%). Respondents who had never prescribed an SGLT-2 inhibitor (n = 18) reported risk of diabetic ketoacidosis (DKA) (100%), off-label status (39%), lack of evidence (39%), withdrawal of support from the European Medicines Agency (17%) and cost (17%) as factors contributing to their decision. Thirty-one respondents (60%) had prescribed a GLP1RA. Among those who had never prescribed a GLP1RA (n = 21), off-label status (57%), lack of evidence (48%), cost (38%) and expected lack of efficacy (14%) were factors affecting their decision. Only five respondents (10%) had prescribed a DPP-IV inhibitor. CONCLUSION Australian endocrinologists commonly prescribe adjuncts to address cardiometabolic concerns in T1DM. DKA risk and off-label status are significant factors contributing to reluctance to prescribe.

Abstract
SGLT2i (sodium glucose transporter type 2 inhibitors) are pharmacological agents that act by inhibiting the SGLT2, by reducing the renal plasma glucose threshold and inducing glycosuria, resulting in a blood glucose lowering effect. In recent years, studies demonstrating some additional positive effects of SGLT2i also in the treatment of T1D have increased progressively. The SGLT2i dapagliflozin and sotagliflozin have been temporarily licensed for use by the European Medical Agency (EMA) as an adjunct to insulin therapy in adults with T1D with a body mass index of 27 kg/m2 or higher. However, in the meantime, the US Food and Drug Administration (FDA) Endocrinologic and Metabolic Drugs Advisory Committee was divided, citing concerns about the main side effects of SGLT2i, especially diabetic ketoacidosis (DKA). The aim of this manuscript was to conduct an update on current evidence and recommendations of the reported use of SGLT2i in the treatment of T1D in humans. Preclinical studies, clinical trial and real world data suggest benefits in glycaemia control and nefro-cardiovascular protection, even though several studies have documented an important increase in the risk of DKA, a serious and life-threatening adverse event of these agents. SGLT2i potentially addresses some of the unmet needs associated with T1D by improving glycaemic control with weight loss and without increasing hypoglycemia, by reducing glycaemic variability. However, due to side effects, EMA recommendation for SGLT2 use on T1D was withdrawn. Further studies will be needed to determine the safety of this therapy in T1D and to define the type of patient who can benefit most from these medications.

Abstract
BACKGROUND Sodium-glucose cotransporter (SGLT)2 inhibitors have displayed beneficial effects on the cardiovascular system in diabetes mellitus (DM) patients. As most clinical trials were performed in Type 2 DM, their effects in Type 1 DM have not been established. OBJECTIVE To evaluate the influence of long-term treatment with SGLT2 inhibitor dapagliflozin on cardiac remodeling, myocardial function, energy metabolism, and metabolomics in rats with Type 1 DM. METHODS Male Wistar rats were divided into groups: Control (C, n = 15); DM (n = 15); and DM treated with dapagliflozin (DM + DAPA, n = 15) for 30 weeks. DM was induced by streptozotocin. Dapagliflozin 5 mg/kg/day was added to chow. STATISTICAL ANALYSIS ANOVA and Tukey or Kruskal-Wallis and Dunn. RESULTS DM + DAPA presented lower glycemia and higher body weight than DM. Echocardiogram showed DM with left atrium dilation and left ventricular (LV) hypertrophy, dilation, and systolic and diastolic dysfunction. In LV isolated papillary muscles, DM had reduced developed tension, +dT/dt and -dT/dt in basal condition and after inotropic stimulation. All functional changes were attenuated by dapagliflozin. Hexokinase (HK), phosphofructokinase (PFK) and pyruvate kinase (PK) activity was lower in DM than C, and PFK and PK activity higher in DM + DAPA than DM. Metabolomics revealed 21 and 5 metabolites positively regulated in DM vs. C and DM + DAPA vs. DM, respectively; 6 and 3 metabolites were negatively regulated in DM vs. C and DM + DAPA vs. DM, respectively. Five metabolites that participate in cell membrane ultrastructure were higher in DM than C. Metabolites levels of N-oleoyl glutamic acid, chlorocresol and N-oleoyl-L-serine were lower and phosphatidylethanolamine and ceramide higher in DM + DAPA than DM. CONCLUSION Long-term treatment with dapagliflozin attenuates cardiac remodeling, myocardial dysfunction, and contractile reserve impairment in Type 1 diabetic rats. The functional improvement is combined with restored pyruvate kinase and phosphofructokinase activity and attenuated metabolomics changes.

Abstract
AIMS/HYPOTHESIS Insulin is the primary treatment for type 1 diabetes. However, alternative glucose-lowering therapies are used adjunctively, but importantly are off-label in type 1 diabetes. Little work has previously been undertaken to evaluate safety with long-term efficacy and cardio-renal benefits of such therapies. We sought to investigate the real-world impact of sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy in individuals with type 1 diabetes in relation to effect on blood glucose levels, adverse events and cardio-renal outcomes. METHODS We performed a retrospective cohort study of all patients aged 18 or over with type 1 diabetes on the TriNetX platform, a global collaborative network providing access to real-time, anonymised medical records. We included patients who had been treated with an SGLT2i or GLP-1 RA for at least 6 months and analysed the efficacy, safety and cardio-renal outcomes 5 years after initiation of therapy. RESULTS We identified 196,691 individuals with type 1 diabetes, 13% of whom were treated with adjunctive glucose-lowering therapy in addition to insulin. Included in the core analysis were 1822 patients treated with a GLP-1 RA and 992 individuals treated with an SGLT2i. Both agents provided clinically meaningful reductions in HbA1c (-2.6 mmol/mol [-0.2%] with SGLT2i and -5.4 mmol/mol [-0.5%] with GLP-1 RA). The SGLT2i treated cohort showed preservation of eGFR over a 5-year period compared with the GLP-1 RA treated cohort (+3.5 ml/min per 1.73 m2 vs -7.2 ml/min per 1.73 m2, respectively), including patients with established chronic kidney disease (CKD). The SGLT2i treated cohort experienced higher rates of diabetic ketoacidosis (DKA) (RR 2.08 [95% CI 1.05, 4.12] p=0.0309) and urinary tract infection/pyelonephritis (RR 2.27 [95% CI 1.12, 4.55] p=0.019) compared with the GLP-1 RA treated cohort. However, the SGLT2i treated cohort were less likely to develop heart failure (RR 0.44 [95% CI 0.23, 0.83] p=0.0092), CKD (RR 0.49 [95% CI 0.28, 0.86] p=0.0118) and be hospitalised for any cause (RR 0.59 [95% CI 0.46, 0.76] p≤0.0001) when compared with the GLP-1 RA treated cohort. CONCLUSIONS/INTERPRETATION Both SGLT2is and GLP-1 RAs have potential benefits as adjunctive agents in type 1 diabetes. SGLT2is provide cardio-renal benefits, despite an increase in the risk of DKA and urinary tract infection compared with GLP-1 RA therapy. Long-term evaluation of the efficacy and safety of these adjunctive therapies is required to guide their use in individuals with type 1 diabetes.

Edwards K, Uruska A, Duda-Sobczak A, Zozulinska-Ziolkiewicz D, Lingvay I. Patient-perceived benefits and risks of off-label use of SGLT2 inhibitors and GLP-1 receptor agonists in type 1 diabetes: a structured qualitative assessment. Ther Adv Endocrinol Metab 2023; 14:20420188231180987. [PMID: 37440840 PMCID: PMC10334016 DOI: 10.1177/20420188231180987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 05/19/2023] [Indexed: 07/15/2023] Open
Abstract
Background Patients with type 1 diabetes mellitus (T1DM) may have suboptimal glucose control and are interested in the use of adjuvant therapies. Objectives To determine, from the patients' perspective, the reasons for initiation of glucagon-like peptide 1 receptor agonist (GLP-1RA) and/or sodium glucose cotransporter 2 inhibitor (SGLT2i) in treating T1DM; perceived benefits/side effects, reasons for discontinuation, and willingness to reinitiate therapy. Design Retrospective chart review with structured telephone interviews. Methods We identified patients with T1DM treated with a GLP-1RA and/or SGLT2i for >3 months at University of Texas Southwestern Medical Center (Dallas, TX, USA) and Poznan University (Poznan, Poland). We conducted structured telephone interviews regarding their experiences. Results We interviewed 68 participants treated with GLP-1RA and 82 with SGLT2i. Treatment was initiated for improving glycemic control (as reported by 61.8% versus 81.7% of GLP-1RA and SGLT2i users, respectively), weight loss/appetite suppression (51.4% versus 23.2%) and to reduce insulin requirement (13.2% versus 11%). Most participants (86.8% of GLP-1RA and 89.0% of SGLT2i users) reported ⩾1 benefit attributed to therapy. Reported benefits were improved glycemic control (reported by 58.8% versus 82.9% of GLP-1RA and SGLT2i users, respectively), weight loss/appetite suppression (63.2% versus 30.5%), and reduced insulin requirement (27.9% versus 34.1%). More GLP-1RA users reported side effects versus SGLT2i users (63.2% versus 36.6%); 22.6% discontinued GLP-1RA due to side effects versus 11.0% SGLT2i users. Diabetic ketoacidosis (DKA) was reported by 4.9% of SGLT2i users, but none in GLP-1RA users. Of those who discontinued medication, 60.7% of GLP-1RA versus 56.0% of SGLT2i prior users were willing to reinitiate treatment. Conclusions Patients with T1DM report initiating adjuvant treatment with GLP-1RA and/or SGLT2i to improve glycemic control and lose weight; most patients reported perceived benefits from these therapies. Side effects (including DKA) are reported more commonly in real life than in clinical trials. Given patient interest in these medications, further studies should evaluate the long-term risk-benefits ratio in larger cohorts.

Abstract
Type 1 diabetes mellitus (DM) occurs when insulin-producing beta cells are destroyed. Destruction of these cells and subsequent loss of insulin signaling can cause diabetic keto acidosis (DKA). This case describes a type 1 DM patient who presented to the emergency department (ED) with nausea and vomiting after glucose like peptide-1 (GLP-1) agonist administration. The patient was noted to have elevated anion gap and elevated beta-hydroxybutyrate with euglycemic blood glucose levels. The patient was confirmed to have a functioning insulin pump and then was sent home with nausea control. The patient was not able to consume food without vomiting and therefore did not administer any postprandial insulin. These symptoms were attributed to the GLP-1 agonist. It contributed to suppression of the patient's appetite while also inhibiting gluconeogenesis, and glycogenolysis resulting in small amounts of blood glucose entering the blood stream, negating the need for a bolus of insulin. The patient was admitted and given dextrose with an insulin drip until the anion gap was returned to normal. As GLP-1 agonists become more popular, this presentation may become more common. If not easily recognized this can lead to patient endangerment and unnecessary medical costs.
