A male patient undergoing hemodialysis in whom the cause of severe hyperkalemia (more than 8 mmol/liter) was found to be an unusual pica is described. His pica consisted of ingestion of burnt match heads (cautopyreiophagia). The potassium content of his daily consumption of burnt matches added 80 mmol to his 45 mmol dietary potassium intake. Hypogeusia and hypozincemia were documented. Oral zinc supplementation (zinc sulfate 220 mg per day for 10 weeks) normalized his plasma zinc level and taste acuity. He abandoned his pica and his plasma potassium level dropped significantly to 5.5 to 6 mmol/liter. It is suggested that inquiry about pica should be part of the dietary history in patients with renal failure.
本文描述了一位接受血液透析的男性患者，其严重高钾血症（超过8 mmol/升）的病因被发现是一种不寻常的异食癖。他的异食癖表现为吞食燃烧过的火柴头（食燃火柴癖）。他每天食用的燃烧火柴中的钾含量，在其每日45 mmol的膳食钾摄入量基础上又增加了80 mmol。记录显示存在味觉减退和低锌血症。口服补锌（硫酸锌220 mg/天，持续10周）使他的血浆锌水平和味觉恢复正常。他不再有异食癖，血浆钾水平显著降至5.5至6 mmol/升。建议对于肾衰竭患者，询问异食癖情况应成为饮食史的一部分。
