Eosinophilia is frequent in pediatrics and concerns regarding its etiology are often raised. Pediculosis capitis is a common ectoparasitic disease in children but is not traditionally associated with changes in laboratory parameters.
We present the case of a healthy, 9-year-old girl who presented with abdominal pain and a history of loose stools (2-3) in the preceding week. Laboratory investigations showed leukocytosis with significant eosinophilia. A thorough investigation concerning the most common causes of eosinophilia was negative. Detailed physical examination and history revealed a persistent scalp infestation with head lice. Successful pediculosis management coincided with the gradual resolution of eosinophilia without recurrence until the most recent follow-up visit twelve months later.
The presented case indicates a possible association between eosinophilia and pediculosis capitis, which was not previously displayed, but also highlights the importance of detailed history and clinical examination. Research focusing on the systematic effects of pediculosis capitis in children could clarify whether it can represent a frank cause of eosinophilia. HIPPOKRATIA 2023, 27 (2):112-114.
嗜酸性粒细胞增多在儿科较为常见，人们常常对其病因表示关注。头虱病是儿童常见的一种体表寄生虫病，但传统上并不认为它与实验室检查参数的变化有关。
我们报告一例健康的9岁女孩，她出现腹痛，且在前一周有腹泻史（每日2 - 3次）。实验室检查显示白细胞增多，并伴有显著的嗜酸性粒细胞增多。针对嗜酸性粒细胞增多最常见病因的全面检查结果为阴性。详细的体格检查和病史询问发现头皮持续存在头虱感染。成功治疗头虱病后，嗜酸性粒细胞增多逐渐消退，直至12个月后的最近一次随访均未复发。
该病例表明嗜酸性粒细胞增多与头虱病之间可能存在此前未被发现的关联，同时也凸显了详细病史和临床检查的重要性。针对头虱病对儿童系统性影响的研究，可能会明确它是否能成为嗜酸性粒细胞增多的一个确切病因。《希波克拉底》2023年，第27卷（第2期）：112 - 114页 。
