Malaria resulted in an estimated 627,000 deaths in 2020, the majority of which occurred in children under 5 years of age. Cerebral malaria (CM) is a severe manifestation of the disease with case fatality rates of up to 40%. Autopsies in children with CM have demonstrated sequestration of Plasmodium falciparum parasites in the brain as well as multiple other organs. Thus, multiple organ dysfunction syndrome (MODS) may be present in pediatric patients with CM, but its frequency and association with mortality have not been evaluated. This is a retrospective study of data collected prospectively from children with CM admitted in Blantyre, Malawi. Physical examination findings and laboratory values necessary to calculate a Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score, a validated method that quantifies organ dysfunction in critically ill children, were abstracted. A total of 145 patients were included. Mortality was 15% (n = 22). Ten patients (7%) had single organ dysfunction, 36 (25%) had two organs involved, 68 (47%) had dysfunction of three organs, and 31 (21%) patients had four organs affected. Beyond neurologic dysfunction, other organ systems involved included hematologic (77%), renal (61%), cardiovascular (44%), and respiratory (1%). The median PELOD-2 score on admission was 4 (interquartile range [IQR] = 3-6) in survivors and 6.5 (IQR = 5-10) in the nonsurvivors (P < 0.0001). Admission PELOD-2 score predicted mortality with an area under the curve of 0.75. MODS is widespread in pediatric patients with CM. Objectively identifying children with MODS, and therefore at an increased risk of mortality, may allow for the allocation of limited resources.
2020 年疟疾导致约 62.7 万人死亡,其中大多数发生在 5 岁以下儿童。脑型疟疾(CM)是该疾病的严重表现,病死率高达 40%。CM 患儿尸检显示疟原虫寄生虫在大脑和其他多个器官中的隔离。因此,CM 患儿可能存在多器官功能障碍综合征(MODS),但其频率及其与死亡率的关联尚未得到评估。这是一项对马拉维布兰太尔收治的 CM 患儿前瞻性数据进行的回顾性研究。提取了体格检查结果和计算儿科逻辑器官功能障碍-2 评分(PELOD-2)所需的实验室值,该评分是一种量化危重病儿童器官功能的验证方法。共纳入 145 例患者。死亡率为 15%(n = 22)。10 例(7%)患者有单一器官功能障碍,36 例(25%)有两个器官受累,68 例(47%)有三个器官功能障碍,31 例(21%)患者有四个器官受累。除神经功能障碍外,其他受累的器官系统包括血液学(77%)、肾脏(61%)、心血管(44%)和呼吸(1%)。幸存者入院时的中位 PELOD-2 评分为 4(四分位距 [IQR] = 3-6),非幸存者为 6.5(IQR = 5-10)(P < 0.0001)。入院时的 PELOD-2 评分对死亡率的预测具有 0.75 的曲线下面积。MODS 在 CM 患儿中广泛存在。客观识别存在 MODS 的患儿,即存在更高死亡率风险的患儿,可能有助于分配有限的资源。
