Clinical Presentation, Electrocardiographic Findings, and Factors Related to the Hospitalization In Mad-Honey Intoxication

Objectives Mad-honey intoxication (MHI) often presents with all kinds of bradyarrhythmias. Despite numerous publications focused on clinical findings, we aim to evaluate poor prognostic implications, ischemia likely electrocardiography (ECG) changes, and detailed ECG findings of MHI in the largest series. Methods This is a retrospective single-center study of 117 MHI patients admitted to emergency service. Results The study had 26 (22.2%) females (median 52.5 years) and 91 (77.8%) males (median 51.0 years). Fifty-six (47.9%) patients had ischemia likely changes on ECG. Multivariate model demonstrated that beta-blocker usage (odds ratio (OR): 52.871; 95% confidence interval (CI): 3.618-772.554 (p=0.004)), atrioventricular junctional rhythm (AVJR) (OR: 5.319; 95%CI: 1.090-25.949 (p=0.039)), and quantity of mad-honey consumption (OR: 1.035; 95% CI: 1.008-1.063 (p=0.011)) are predictors of hospitalization. ROC curve analysis showed cutoff value of mad-honey consumption quantity 24.79 g had 57% sensitivity and 68% specificity for predicting hospitalization (AUC: 0.7, 95% CI: 0.55-0.816, p=0.027). In addition, all hospitalized cases were male. Conclusion Our study has shown that male gender, AVJR, the quantity of mad-honey consumption, and beta-blocker usage are high-risk criteria for hospitalization in MHI patients. Furthermore, ischemia likely ECG changes is often observed with MHI even independently from hypotension or bradycardia.
