Severe malaria complicated by circulatory shock is known as algid malaria. Cases of severe imported malaria are seen increasingly frequently in emergency departments in the United States, Europe, and other locales. The optimal volume resuscitation strategy for patients with severe malaria is not well-defined. A 20-year-old woman, who immigrated 2 weeks ago from Niger, Africa, presented to the emergency department of an urban teaching hospital with fever, hypotension, and malaise. She was resuscitated with 5.5 L of normal saline solution and norepinephrine. Thin blood smear demonstrated Plasmodium falciparum with parasitemia of 10% to 15%. She had rapid reversal of circulatory shock, cleared her parasitemia in less than 48 hours with antimalarial therapy, and was discharged home on hospital day 6 in good condition. The optimal resuscitation strategy for algid malaria is unknown, and volume restriction has been advocated as a means to prevent life-threatening cerebral and pulmonary edema. Although not identical, the late inflammatory response in severe malaria leading to capillary permeability shares many similarities with the immunologic response in bacterial sepsis. Our case report discusses a patient with severe imported malaria complicated by shock, successfully managed with large-volume fluid resuscitation, hemodynamic optimization, early antimalarial agents, and broad-spectrum antibiotics. This report questions the strategy of cautious fluid resuscitation in algid malaria and suggests that case series comparing goal-directed resuscitation to historic controls along with prospective multicenter controlled trials should be conducted to determine the best fluid resuscitation strategy.
严重疟疾合并循环性休克被称为冷感型疟疾。在美国、欧洲和其他地区的急诊科,越来越频繁地出现严重输入性疟疾病例。对于严重疟疾患者,最佳的容量复苏策略尚未明确。
一位 20 岁的女性,两周前从非洲尼日尔移民而来,因发热、低血压和不适就诊于城市教学医院的急诊科。她接受了 5.5L 的生理盐水和去甲肾上腺素复苏治疗。薄血涂片显示恶性疟原虫感染,寄生虫血症为 10%至 15%。她迅速逆转了循环性休克,在不到 48 小时内用抗疟药物清除了寄生虫血症,并在住院第 6 天出院时情况良好。冷感型疟疾的最佳复苏策略尚不清楚,有人主张限制液体量以预防危及生命的脑和肺水肿。虽然不尽相同,但严重疟疾导致毛细血管通透性增加的晚期炎症反应与细菌性败血症中的免疫反应有许多相似之处。我们的病例报告讨论了一例严重输入性疟疾合并休克的患者,该患者通过大量液体复苏、血流动力学优化、早期抗疟药物和广谱抗生素成功治疗。本报告对冷感型疟疾中谨慎的液体复苏策略提出质疑,并建议进行比较目标导向性复苏与历史对照的病例系列研究,并进行前瞻性多中心对照试验,以确定最佳的液体复苏策略。
