Liraglutide-induced Acute Gastroparesis

Confounding Factors in the Association Between Glucagon-Like Peptide-1 Receptor Agonist Use and Retained Gastric Contents in Asymptomatic Patients Undergoing Upper Gastrointestinal Endoscopy: A Retrospective Study

Introduction The use of glucagon-like peptide-1 receptor agonists (GLP-1 RA) has gained acceptance in managing diabetic and non-diabetic patients, thanks to its benefits in treating obesity and improving cardiovascular outcomes. The potential ability of GLP-1 RA to cause retained gastric contents (RGC) which can lead to aspiration has led to the recommendation to withhold GLP-1 RA for at least one week prior to elective surgeries and procedures, including upper endoscopies and colonoscopies. However, many co-medications and conditions associated can contribute to delayed gastric emptying (DGE) and these need to be controlled to establish a clear association and incidence, which has been largely missing in most studies and reports. Our aim was to assess clinically significant delayed gastric emptying (CSDGE) related to GLP-1 RA in a "real world" situation by controlling for some common confounding factors. Method We carried out an eight-year retrospective single-center study to assess the relationship between CSDGE and the use of GLP-1 RA among asymptomatic patients undergoing upper endoscopies while controlling for common confounding factors. Result Out of the 3415 patients who had esophagogastroduodenoscopy (EGD) with or without colonoscopy (Ew/woC) during the eight-year period, 129 eligible patients were found to have CSDGE. The use of GLP-1 RA was associated with the lowest percentage frequency distribution of CSDGE, at 2%, and opiate accounted for more percentage frequency distribution, at 35%. The odds ratio for patients on GLP-1 RA who developed CSDGE was 2.5 (95% CI 0.75-8.29). All patients who had CSDGE while on GLP-1 RA were also on other medications or had conditions associated with DGE. Conclusion Our result confirmed the possible effect of confounding factors in the association between CSDGE and GLP-1 RA among asymptomatic patients undergoing Ew/woC. While the need to ensure patients' safety cannot be overemphasized, the proper approach currently favors assessing patients on a case-by-case basis while we await the results of large prospective controlled studies.

Is it necessary to stop glucagon-like peptide-1 receptor agonists prior to endoscopic procedure? A retrospective study

BACKGROUND

Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are effective in diabetes and obesity, reducing hyperglycemia by increasing insulin release and delaying gastric emptying. However, they can cause gastroparesis, raising concerns about aspiration during procedures. Recent guidelines advise discontinuing GLP-1 RA before surgery to reduce the risk of pulmonary aspiration.

AIM

To evaluate the effect of GLP-1 RAs on gastric residual contents during endoscopic procedures.

METHODS

A retrospective chart review at BronxCare Health System, New York, from January 2019 to October 2023, assessed gastric residue and aspiration in GLP-1 RA patients undergoing endoscopic procedures. Two groups were compared based on dietary status before the procedure. Data included demographics, symptoms of gastroparesis, opiate use, hemoglobin A1c, GLP-1 agonist indication, endoscopic details, and aspiration occurrence. IBM SPSS was used for analysis, calculating means, standard deviations, and applying Pearson's chi-square and t-tests for associations, with P < 0.05 as being significant.

RESULTS

During the study, 306 patients were included, with 41.2% on a clear liquid/low residue diet and 58.8% on a regular diet before endoscopy. Most patients (63.1%) were male, with a mean age of 60 ± 12 years. The majority (85.6%) were on GLP-1 RAs for diabetes, and 10.1% reported digestive symptoms before endoscopy. Among those on a clear liquid diet, 1.5% had residual food at endoscopy compared to 10% on a regular diet, which was statistically significant (P = 0.03). Out of 31 patients with digestive symptoms, 13% had residual food, all from the regular diet group (P = 0.130). No complications were reported during or after the procedures.

CONCLUSION

The study reflects a significant rise in GLP-1 RA use for diabetes and obesity. A 24-hour liquid diet seems safe for endoscopic procedures without aspiration. Patients with upper gastrointestinal symptoms might have a higher residual food risk, though not statistically significant. Further research is needed to assess risks based on diabetes duration, gastroparesis, and GLP-1 RA dosing, aiming to minimize interruptions in therapy during procedures.

Adverse drug reactions of GLP-1 agonists: A systematic review of case reports

BACKGROUND AND AIM

The importance of glucagon-like peptide-1 (GLP-1) agonists is increasing because of its blood sugar controlling and weight loss properties. The data regarding safety of GLP-1 agonists are limited. This study aims to review case reports and case series on adverse drug reactions (ADRs) of GLP-1 agonist.

METHODOLOGY

A comprehensive search was performed in PubMed/Medline, Scopus and Embase to identify literatures. Bibliographic search and open search in Google, Google Scholar, SpringerLink and ResearchGate was performed to identify additional studies. Case reports and case series published the ADRs by the use of GLP-1 agonists in type 2 diabetes patients were included in the study. Reviews, experimental studies, observational studies, grey literature and non English studies were excluded.

RESULTS

The study identified 120 cases of GLP-1 agonists associated ADRs (liraglutide - 46, exenatide - 46, dulaglutide - 20, semaglutide - 4, albiglutide - 2, lixisenatide - 2). The major ADRs reported was gastrointestinal disorders (n = 40) followed by renal (n = 23), dermatologic (n = 14), hepatic (n = 10), immunologic (n = 13), endocrine/metabolic (n = 7), hematologic (n = 3), angioedema (n = 3), neurologic (n = 2), cardiovascular (n = 2) and 1 from each of psychiatric, reproductive, generalized edema problems.

CONCLUSION

Gastrointestinal problems, particularly pancreatitis was the more frequently reported adverse drug reaction associated with GLP-1 agonist. The most adverse drug reactions were observed with liraglutide and exenatide.

Gastroparesis With the Initiation of Liraglutide: A Case Report

Gastroparesis is a syndrome that is manifested by gastrointestinal symptoms and delayed gastric emptying without evidence of mechanical obstruction. Herein, we present the case of an 18-year-old diabetic female patient who developed clinical features suggestive of gastroparesis after initial doses of liraglutide. Although rare, drug-induced gastroparesis should be contemplated in diabetic patients with a history of recent commencement of liraglutide, particularly at higher doses. Management of drug-induced gastroparesis is largely symptomatic.
