[Cardiogenic shock following yew needle poisoning : Digoxin immune fab, va-ECMO and albumin dialysis for the treatment of a suicidal yew leaf poisoning]

[Severe intoxication after yew (Taxus) ingestion-case report and literature review]

BACKGROUND

Severe yew (Taxus) intoxication is a rare condition that can lead to life-threatening cardiac arrhythmia. The survival of patients requires highly specialized emergency and intensive care treatment.

OBJECTIVES

Systematic overview of the clinical picture and important treatment options.

METHODS

Case report of severe yew intoxication with subsequent literature review of comparable case reports. Analysis of 33 case reports with a total of 37 critically intoxicated patients from the years 2000-2024 from Europe and North America.

RESULTS

Severe yew intoxications were almost exclusively the result of suicidal intent. Patients average age was 33 (± 14.5) years. The use of antiarrhythmic drugs and electrical stimulation of the heart often proved to be ineffective or deteriorating in its effect over time. The use of lipid emulsion and/or digoxin-specific Fab fragments has little evidence. The average duration of a clinically relevant arrhythmogenic effect was 22±11.7 h.

CONCLUSIONS

The management of yew intoxication is primarily limited to symptomatic treatment. The availability of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in a "bridge-to-recovery" concept appears to be of utmost importance.

Characteristics of emergency department presentations following ingestion of Taxus baccata (yew)

OBJECTIVE

Presentations of Taxus baccata (yew) poisoning can range between asymptomatic cases and life-threatening cardiotoxicity - depending on the amount ingested. This study aimed to describe emergency department (ED) presentations after yew exposure, and covers their clinical presentation, diagnostic and specific treatment, to contribute to optimising intreatment and prophylaxis.

METHODS

Retrospective observational study of cases (≥ 16 years of age) presenting at the ED of the University Hospital of Bern, Switzerland, from 1 May 2012 to 31 May 2020 following reported yew exposure. Cases were retrieved from the electronic patient database using full-text terms.

RESULTS

During the study period, 55 presentations (11 patients) of the 350,381 ED attendances were included. All patients were female and the median age on first presentation was 22 years (range 16-48). All 10 patients with intentional intake had previous diagnoses of psychiatric disorders. Commonly reported symptoms on presentation were gastrointestinal disturbances (31 presentations, 56%), neurological (six presentations, 11%) and subjective cardiovascular symptoms (five presentations, 9%). The most frequent clinical findings on presentation were tachycardia (15 presentations, 27%) and hypotension (11 presentations, 20%). In 52 presentations (95%), gastroscopic extraction of the leaves was performed, activated charcoal was administered in 25 cases (45%), and there were no fatalities. In the majority of the cases (40, 73%), the patient was admitted to psychiatric care and in 10 (18%) the patient was discharged home.

CONCLUSION

ED presentations after yew exposure appear to be rare, but potentially life-threatening and commonly observed in this study in young female patients with underlying psychiatric diseases. In this case series, gastroscopic extraction and activated charcoal application were commonly performed and there were no fatalities.

Cardiogenic shock due to yew poisoning rescued by VA-ECMO: case report and literature review

Ingestion of leaves of the European yew tree (Taxus baccata) can result in fatal cardiac arrhythmias and acute cardiogenic shock. This cardiotoxicity derives from taxine alkaloids that block cardiac voltage-gated sodium and calcium channels. Prompt initiation of venoarterial extracorporeal membrane oxygenation is essential to bridge these critically ill patients to recovery, as there is no antidote available. We here report a 39-year old patient with toxic cardiogenic shock after yew poisoning, who was successfully rescued by venoarterial extracorporeal membrane oxygenation and had a full neurological recovery. This report emphasizes the role of intoxications as reversible causes of cardiac arrest and adds further evidence to the body of existing literature thus encouraging the early use of venoarterial extracorporeal membrane oxygenation in patients with yew poisoning and cardiogenic shock.

Extracorporeal hemoadsorption with the CytoSorb device as a potential therapeutic option in severe intoxications: Review of the rationale and current clinical experiences

WHAT IS KNOWN AND OBJECTIVE

Many severe intoxications occur with substances with no specific antidote, which is why methods of extracorporeal elimination represent a particularly useful and even critical component in their management. The purpose of this review is to summarize the accumulating evidence and clinical results from the application of CytoSorb hemoadsorption therapy in patients with severe intoxications.

COMMENT

The technology represents a promising technique with an increasing number of publications in a variety of severe intoxication scenarios suggesting that early intervention might provide rapid substance removal with subsequent overall clinical improvement.

WHAT IS NEW AND CONCLUSION

Given the tremendous challenges in performing prospective, randomized trials in this field, the strong safety profile of the device and the high acuity of these life-threatening situations, CytoSorb should be considered as a therapeutic option in severe intoxications, particularly when direct antidotes are not available. However, further clinical data are desirable to provide precise recommendations.

Taxine alkaloid poisoning successfully supported with venoarterial extracorporeal membrane oxygenation: a case report

BACKGROUND

Ingestion of the berries of the European yew tree can result in fatal cardiac arrhythmias.

CASE SUMMARY

A 53-year-old female presented to our emergency department following ingestion of ∼200 European yew tree berries. At presentation, she was in cardiogenic shock due to a mixture of tachy- and bradyarrhythmias including ventricular tachycardia, atrial fibrillation with slow ventricular response and prolonged ventricular conduction, and periods of asystole. She was referred to a specialist cardiac centre and promptly established on mechanical circulatory support with venoarterial extracorporeal membrane oxygenation (V-A ECMO) by a retrieval team. Following resolution of her arrhythmias, she was weaned from V-A ECMO after 4 days of support and was discharged home with full neurological recovery on Day 12.

DISCUSSION

Poisoning can lead to acute reversible but potentially fatal cardiogenic shock. We believe that access to prompt initiation of V-A ECMO was key to this patient's survival.
