Pediatric falciparum malaria is associated with high morbidity and mortality rates. Cerebral malaria and renal failure are common among children with a high percentage of malaria-infected red blood cells. We report 3 cases of imported pediatric falciparum malaria with central nervous system involvement and/or renal failure that were treated initially with intravenous antimalarial therapy, with no clinical improvement. Red blood cell exchange transfusion (RBCET) was started; this resulted in decreases in the percentages of parasitized red blood cells of 80% to 90%. The RBCET was performed with either an automated 1-blood volume or manual 1.5-blood volume exchange. Most cases of falciparum malaria can be treated with intravenously administered antimalarial agents alone. However, for children who have high percentages of parasitized red blood cells with central nervous system involvement and/or renal failure, the use of RBCET as an adjunct treatment should be considered.
小儿恶性疟原虫疟疾与高发病率和死亡率相关。脑型疟疾和肾衰竭在感染疟原虫的红细胞比例较高的儿童中很常见。我们报告了3例输入性小儿恶性疟原虫疟疾,伴有中枢神经系统受累和/或肾衰竭,最初采用静脉抗疟治疗,但无临床改善。开始进行红细胞置换输血(RBCET);这导致被寄生红细胞的百分比降低了80%至90%。RBCET采用自动1个血容量或手动1.5个血容量置换进行。大多数恶性疟原虫疟疾病例仅用静脉注射抗疟药物即可治疗。然而,对于感染疟原虫的红细胞比例较高且伴有中枢神经系统受累和/或肾衰竭的儿童,应考虑使用RBCET作为辅助治疗。
