Hypoglycemia following the use of glucagon-like peptide-1 receptor agonists: a real-world analysis of post-marketing surveillance data

The role of glucagon-like peptide-1/GLP-1R and autophagy in diabetic cardiovascular disease

Diabetes leads to a significantly accelerated incidence of various related macrovascular complications, including peripheral vascular disease and cardiovascular disease (the most common cause of mortality in diabetes), as well as microvascular complications such as kidney disease and retinopathy. Endothelial dysfunction is the main pathogenic event of diabetes-related vascular disease at the earliest stage of vascular injury. Understanding the molecular processes involved in the development of diabetes and its debilitating vascular complications might bring up more effective and specific clinical therapies. Long-acting glucagon-like peptide (GLP)-1 analogs are currently available in treating diabetes with widely established safety and extensively evaluated efficacy. In recent years, autophagy, as a critical lysosome-dependent self-degradative process to maintain homeostasis, has been shown to be involved in the vascular endothelium damage in diabetes. In this review, the GLP-1/GLP-1R system implicated in diabetic endothelial dysfunction and related autophagy mechanism underlying the pathogenesis of diabetic vascular complications are briefly presented. This review also highlights a possible crosstalk between autophagy and the GLP-1/GLP-1R axis in the treatment of diabetic angiopathy.

Immune checkpoint inhibitors-associated diabetes and ketoacidosis were found in FAERS: A Real-World Evidence Database Study

OBJECTIVE

To investigate the risk of developing diabetes and ketoacidosis in clinical patients with Immune checkpoint inhibitors (ICIs).

METHODS

We looked in the FDA Adverse Event Reporting System (FAERS) for reports of ICIs-associated DM and ketoacidosis between January 2004 and March 2022. We explored the signals using fourfold table-based proportional imbalance algorithms. Patient characteristics, country distribution, and outcomes of adverse reactions were described. Kruskal-Wallis test was used to compare the time of onset and prognosis of adverse reactions.

RESULTS

A total of 2,110 reports of ICIs-related DM were included in the study. The largest number of reports was from Japan (752, 35.64%), followed by the United States and France (624, 29.57%; 183, 8.67%). Seven drugs detected signals of DM and ketoacidosis according to four proportional imbalance algorithms: Nivolumab, Pembrolizumab, Cemiplimab, Dostarlimab, Atezolizumab, Avelumab, and Durvalumab. Diabetes and ketoacidosis generally occured early in the course of ICIs treatment, the median time to event onset was 144.5 (interquartile range 27-199) days. ICIs-related diabetes and ketoacidosis events resulted in 934 major medical events (44.3%), 524 hospitalizations (24.8%), 60 life-threatening events (2.8%), 42 deaths (2.0%), and 39 disability events (1.8%).

CONCLUSION

The study reveals the risk and characteristics of diabetes and ketoacidosis associated with ICIs, which may provide evidence for post-marketing evaluation. Careful consideration should be given to the possibility of an increased risk of diabetes and ketoacidosis after using ICIs, and careful monitoring for diabetes and ketoacidosis is recommended.

Glucagon-Like Peptide-1 (GLP-1) during Ramadan: Narrative Review of the Published Literature

Ramadan fasting, a religious practice observed by Muslims worldwide, involves abstaining from eating, drinking, smoking, and using oral medications from dawn to dusk during the ninth lunar month. Studies have demonstrated that fasting during Ramadan has been shown to increase HDL cholesterol, leptin, adiponectin, and insulin sensitivity, as well as lower several hemostatic risk factors for cardiovascular diseases. Additionally, it may result in a drop in blood sugar levels, especially in diabetics who are also on blood sugar-lowering medicine. Hypoglycemia, characterized by low blood sugar levels, could also result from fasting during Ramadan. The GLP-1 (glucagon-like peptide-1) hormone plays a significant role in regulating glucose metabolism and insulin secretion, and Ramadan fasting can affect its production and release in the gut. Research contributes to our understanding of the utilization of GL-1 medications during Ramadan among patients, broadening therapy alternatives and offering insightful information for well-informed decision-making. Therefore, this narrative review aims to explore the current evidence that studies the safety and efficacy of GLP-1 agonists during Ramadan for nondiabetic and diabetic patients to ensure healthy fasting during Ramadan.

Urinary tract infections and genital mycotic infections associated with SGLT‑2 inhibitors: an analysis of the FDA Adverse Event Reporting System

BACKGROUND

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are a class of antihyperglycemic agents, including canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin. Risk of urinary tract infections (UTIs) and genital mycotic infections (GMIs) associated with SGLT‑2 inhibitors is of great clinical significance. The study aimed to assess the association between SGLT-2 inhibitors and occurrences of UTIs and GMIs using the FDA Adverse Event Reporting System (FAERS) database.

METHODS

We used OpenVigil 2.1-MedDRA-v24 to query the FAERS database. Disproportionality analysis was performed to detect adverse event signals. Reporting Odds Ratio (ROR) and Proportional Reporting Ratio (PRR) were calculated to measure the disproportionality.

RESULTS

A total of 45,256 reports related to the use of SGLT-2 inhibitors, including 1,714 UTI cases and 438 GMI cases, were retrieved. Potential positive signals for UTIs and GMIs were identified for canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin in adult patients of all ages and both sexes.

CONCLUSIONS

Data mining in the FAERS database suggests strong association between SGLT-2 inhibitors and UTIs/GMIs. These findings provide real-world evidence on the potential risk of UTIs/GMIs related to SGLT-2 inhibitors.

Drug-induced hypoglycemia: a disproportionality analysis of the FAERS database

BACKGROUND

Hypoglycemia is an adverse event (AE) that cannot be ignored in clinical practice. This study aimed to identify the most common and top drugs associated with the risk of hypoglycemia based on the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database.

RESEARCH DESIGN AND METHODS

We used OpenVigil 2.1 pharmacovigilance analytics platform to query FAERS database and data from 2004 to 2023 were retrieved. The Medical Dictionary for Regulatory Activities (MedDRA) was used to identify hypoglycemia cases, and DrugBank database was used to determine drug generic names.

RESULTS

A total of 11,155,106 AEs reports were identified, of which 28,443 (0.25%) were related to hypoglycemia. Metformin (6926 cases) was associated with most cases of hypoglycemia. According to the disproportionality analysis, the top five drugs with the highest ROR and PRR were penamecillin, nikethamide, sotagliflozin, norethandrolone, glimepiride/pioglitazone. Nineteen of the top 50 drugs did not have hypoglycemia indicated in the package insert.

CONCLUSIONS

By analyzing the FAERS database, we listed drugs with a strong hypoglycemic signal for which the label does not provide a reminder. Notably, the potential hypoglycemia risks are of great importance and should be closely monitored in medical practice.

Gastrointestinal disorders potentially associated with Semaglutide: an analysis from the Eudravigilance Database

BACKGROUND

Semaglutide is a Glucagon-like peptide-1 receptor agonist used in the second-line treatment of poorly controlled type 2 diabetes and can be used in monotherapy or associated with other oral antidiabetics or even insulin, increasing the effectiveness of the treatment. This work aims to analyze the profile of adverse drug reactions reported for semaglutide in Eudravigilance.

RESEARCH DESIGN AND METHODS

Data on Individual Cases Safety Reports were obtained from the database of the centralized European spontaneous reporting system Eudravigilance by accessing www.adrreports.eu. (1 December 2021).

RESULTS

It is possible to observe a high prevalence of gastrointestinal disorders (N = 3502, 53.2%). The most severe reported cases were primarily gastrointestinal disorders, metabolic, and nutritional disorders, eye disorders, renal and urinary disorders and cardiac disorders, with an evident higher prevalence of adverse gastrointestinal events both in oral and injectable dosage form (N = 133, 50.0% vs N = 588, 47.2%, respectively). Through a comparative analysis, semaglutide had a greater number of reported gastrointestinal adverse events compared to sitagliptin and empaglifozin (p < 0.00001).

CONCLUSIONS

Semaglutide has a good safety profile, however the definition of subgroups within the type 2 diabetes population who are particularly prone to develop serious adverse event when treated with GLP-1 RAs is crucial.

GLP-1 receptor agonist as a modulator of innate immunity

Glucagon-like peptide-1 (GLP-1) is a 30-amino acid hormone secreted by L cells in the distal ileum, colon, and pancreatic α cells, which participates in blood sugar regulation by promoting insulin release, reducing glucagon levels, delaying gastric emptying, increasing satiety, and reducing appetite. GLP-1 specifically binds to the glucagon-like peptide-1 receptor (GLP-1R) in the body, directly stimulating the secretion of insulin by pancreatic β-cells, promoting proliferation and differentiation, and inhibiting cell apoptosis, thereby exerting a glycemic lowering effect. The glycemic regulating effect of GLP-1 and its analogues has been well studied in human and murine models in the circumstance of many diseases. Recent studies found that GLP-1 is able to modulate innate immune response in a number of inflammatory diseases. In the present review, we summarize the research progression of GLP-1 and its analogues in immunomodulation and related signal pathways.

Gastrointestinal adverse events associated with semaglutide: A pharmacovigilance study based on FDA adverse event reporting system

Background

Semaglutide was approved for treatment of type 2 diabetes mellitus (T2DM) and chronic weight management in obesity or overweight adults. However, real-world data regarding its long-term gastrointestinal safety and tolerability in large sample population are incomplete. We evaluated semaglutide-associated gastrointestinal safety signals by data mining of the FDA pharmacovigilance database.

Methods

Reporting odds ratio (ROR) was employed to quantify the signals of semaglutide-related gastrointestinal adverse events (AEs) from 2018 to 2022. Serious and non-serious cases were compared by Mann-Whitney U test or Chi-squared (χ²) test, and signals were prioritized using a rating scale.

Results

We identified 5,442 cases of semaglutide-associated gastrointestinal AEs, with 45 signals detected, ranging from a ROR₀₂₅ of 1.01 (hypoaesthesia oral) to 42.03 (eructation), among which 17 AEs were identified as new and unexpected signals. Patient age (p < 0.001) and body weight (p = 0.006) rather than sex (p = 0.251) might be associated with an increased risk of gastrointestinal AEs severity. Notably, the association between semaglutide and gastrointestinal disorders remained when stratified by age, body weight, sex and reporter type. One strong, 22 moderate and 22 weak clinical priority signals were defined. The median time-to-onset (TTO) for strong clinical priority signal was 23 days, while for moderate and weak, they were 6 and 7 days, respectively. All of the disproportionality signals had early failure type features, suggesting that the risk of gastrointestinal AEs occurrence gradually decreased over time.

Conclusion

Our study provided a deeper and broader understanding of semaglutide's gastrointestinal safety profiles, which would help healthcare professionals to mitigate the risk of gastrointestinal AEs in clinical practice.

Can glucagon-like peptide-1 receptor agonists cause acute kidney injury? An analytical study based on post-marketing approval pharmacovigilance data

Clinical studies after marketing have shown that the use of glucagon-like peptide-1 receptor agonist(GLP-1RA) may lead to acute kidney injury(AKI). However, few epidemiological studies have investigated the risk, clinical features, and outcomes of AKI caused by different GLP-1RA. In this study, Adverse Event Reporting System (FAERS) data were used to compare the association between different GLP-1RA and AKI in the real world.

METHODS

FAERS data from January 2004 to December 2021 were mined using disproportionality analysis and Bayesian analysis to determine the correlation between different GLP-1RA and AKI, and the onset time, mortality, and hospitalization rate of different GLP-1RA were analyzed.

RESULTS

We identified 2670 cases of AKI events associated with GLP-1RA, of which liraglutide was the most commonly reported (34.98%). The patients with AKI were mainly males (47.94%), and the age group was mainly 45-84 years old (73.15%). obese patients with weight more than 99kg (24.42%) were more likely to have AKI. According to different signal mining methods, reporting odds ratio (ROR) (1.50, 95% confidence interval =1.41-1.60) and Bayesian confidence Propagation neural network (0.57, 95% confidence interval =0.54), liraglutide was more strongly associated with AKI than other GLP-1RA. The median time to onset of AKI was 63 days [quartile range (IQR): 15-458.5 days]. In addition, the hospitalization rate and fatality rate of patients with GLP-1RA-related AKI were 45.28% and 4.23% respectively.

CONCLUSIONS

Based on the data in the FAERS database, we analyzed the risk, onset time, and adverse reaction outcomes of GLP-1RA-induced AKI in detail. The results showed that liraglutide had the highest risk of AKI. From the early stage of treatment, we need to monitor patients' renal function regularly, especially for patients with high kidney risks such as obesity and age.
