Severe malaria is invariably caused by Plasmodium falciparum. In India, both adults and children are affected by severe malaria. However, children are more prone for developing anemia and convulsions as manifestations of severe malaria, while acute renal failure and jaundice are more common among adults. Pregnant women are vulnerable to hypoglycemia, anemia and pulmonary complications. The case-fatality rate due to severe malaria is 10-15% in spite of therapy but it increases in the presence of renal failure or respiratory distress (pulmonary edema or ARDS). Of late, multi-organ failure and high mortality figures are being reported increasingly from different parts of India. Early diagnosis and prompt treatment will reduce the mortality due to malaria. Cerebral malaria should always be suspected in a patient with altered sensorium in a malaria-endemic area. However, other causes of unconsciousness such as encephalitis, meningitis or hepatic coma should also be excluded. Parenteral quinine is the mainstay of therapy. A recent multi-centric study has demonstrated the efficacy of intravenous artesunate in reducing the mortality by 30%. The usefulness of adjunct therapy is still controversial.
重症疟疾 invariably 由恶性疟原虫引起。在印度,成人和儿童都会受到重症疟疾的影响。然而,儿童更容易出现贫血和惊厥作为重症疟疾的表现,而急性肾衰竭和黄疸在成人中更为常见。孕妇易患低血糖、贫血和肺部并发症。尽管进行了治疗,重症疟疾的病死率仍为 10% - 15%,但在出现肾衰竭或呼吸窘迫(肺水肿或急性呼吸窘迫综合征)时病死率会升高。最近,印度不同地区越来越多地报告多器官衰竭和高死亡率病例。早期诊断和及时治疗将降低疟疾导致的死亡率。在疟疾流行地区,对于意识状态改变的患者应始终怀疑患有脑型疟疾。然而,其他导致昏迷的原因,如脑炎、脑膜炎或肝昏迷也应排除。肠外奎宁是治疗的主要药物。最近一项多中心研究表明,静脉注射青蒿琥酯可使死亡率降低 30%。辅助治疗的有效性仍存在争议。
