Zusammenfassung

Wir berichten über einen 34-jährigen Italiener, der in eine Rosskastanie gebissen, diese jedoch nicht komplett verzehrt hat, sondern aufgrund der Bitterkeit teilweise wieder ausspuckte. Nach 5 Minuten traten Übelkeit und Dyspnoe auf, nach 10 Minuten sei es zu einem generalisierten Erythem und Bewusstlosigkeit gekommen, fremdanamnestisch wird von einer Defäkation berichtet. Esskastanien (Maronen) habe er bislang immer gut vertragen. Bei der allergologischen Diagnostik wurden RAST-Untersuchungen und Pricktestungen mit Rosskastanie und Esskastanie durchgeführt. Im RAST ließen sich keine spezifischen IgE-Anti-körper nachweisen.

Summary

We report on a 34-year-old male Italian who bit into a horse chestnut. He did not completely consume it but partly spit it out because of the bitter taste. Nausea and dyspnea appeared after five minutes and a generalised erythema and unconsciousness occured after ten minutes. Until this time, he always had been able to eat sweet chestnuts. Radioallergosorbent test examinations and prick tests with horse chestnut and sweet chestnut were carried out during the allergological diagnostics. The radioallergosorbent test did not detect specific Ig-E-antibodies. The positive raction of the pricktest to horse chestnut as well as the anaphylactoid symptoms when consuming the horse chestnut can be assigned to the toxic effect of the primary component aescine.
