White or false hellebore (Veratrum album) has a toxicological relevance because of the potential for misidentification of this plant as yellow gentian (Gentiana lutea).
We report a retrospective case series of 11 children (8-12 years) with accidental intake of V. album at a youth camp where they had collected herbs for preparing fresh herb tea. Two children (18%) remained asymptomatic. Nine (82%) developed mild gastrointestinal symptoms, six (55%) presented neurological symptoms, and three (27%) showed bradycardia. All children recovered completely within 10 h of ingestion. The plant was identified at the emergency department; however, detection of veratridine and cevadine by means of high-performance liquid chromatography-Mass spectrometry from the blood of the child with the most severe symptoms was negative (limit 0.01 ng/mL).
Veratrum species contain more than 200 different alkaloids, which are the principal toxins and are responsible for most clinical symptoms. There are likely multiple mechanisms of toxicity and some of them are only partially understood. The opening of voltage-gated sodium channels is probably one of the most relevant pathophysiological mechanisms.
Veratrum album intoxication in children demonstrated the same clinical course as observed in adults. Accidental ingestion of a low dose of the plant had a favorable outcome with supportive care.
白曼陀罗(Veratrum album)由于存在将其与黄龙胆(Gentiana lutea)混淆的可能性,因此具有毒理学相关性。
我们报告了一个青少年营地中 11 例(8-12 岁)儿童意外摄入白曼陀罗的回顾性病例系列,他们在那里采集草药来制作新鲜草药茶。两名儿童(18%)无症状。九名(82%)出现轻度胃肠道症状,六名(55%)出现神经系统症状,三名(27%)出现心动过缓。所有儿童在摄入后 10 小时内完全康复。在急诊室识别出该植物;然而,通过高效液相色谱-质谱法从症状最严重的儿童的血液中检测到藜芦定和蟾毒灵的结果为阴性(限量 0.01 ng/mL)。
藜芦属植物含有 200 多种不同的生物碱,这些生物碱是主要毒素,也是大多数临床症状的主要原因。可能存在多种毒性机制,其中一些机制尚未完全了解。电压门控钠离子通道的开放可能是最相关的病理生理机制之一。
儿童摄入白曼陀罗表现出与成人相同的临床过程。低剂量植物的意外摄入通过支持性护理获得了良好的结果。
