Prolonged, multiple seizures complicate a high proportion of cases of childhood cerebral malaria, and several studies have shown an association between these and neurological sequelae. We prospectively studied 65 patients (38 female) admitted to Kilifi Hospital in 1994. Electroencephalographic recordings (EEGs) were made at 12-hourly intervals, with continuous recordings made on a cerebral function analysing monitor (CFAM). Survivors were seen one month after discharge. Cerebral computerized tomography was performed on children with neurological sequelae. Sixty-two percent of patients had seizures following admission, of whom half had an episode of status epilepticus. Fifty-two percent of seizures were partial motor, 34% generalized tonic-clonic, and 14% partial with secondary generalization. In 22%, coma appeared to be due to a prolonged postictal state. Ten children had subtle motor seizures. Posterior parieto-temporal discharges were the most common EEG finding. Seven children died, eight developed neurological sequelae, and 50 (77%) recovered fully. Status epilepticus was associated with the development of neurological sequelae. Prolonged, multiple seizures may play an important part in the pathogenesis of coma in childhood cerebral malaria, and are likely to contribute to both the morbidity and mortality of this disease.
长时间的多次癫痫发作使很大一部分儿童脑型疟疾病例复杂化,多项研究表明这些发作与神经后遗症之间存在关联。我们对1994年入住基利菲医院的65例患者(38名女性)进行了前瞻性研究。每隔12小时进行一次脑电图记录(EEG),并在脑功能分析监测仪(CFAM)上进行连续记录。幸存者在出院后一个月接受随访。对有神经后遗症的儿童进行了脑部计算机断层扫描。62%的患者入院后出现癫痫发作,其中一半发生了癫痫持续状态。52%的癫痫发作为部分运动性发作,34%为全身性强直阵挛发作,14%为部分性发作继发全身性发作。22%的患者昏迷似乎是由于长时间的发作后状态所致。10名儿童出现轻微运动性癫痫发作。顶叶后颞叶放电是最常见的脑电图表现。7名儿童死亡,8名出现神经后遗症,50名(77%)完全康复。癫痫持续状态与神经后遗症的发生有关。长时间的多次癫痫发作可能在儿童脑型疟疾昏迷的发病机制中起重要作用,并且很可能导致这种疾病的发病率和死亡率上升。
