Endothelial dysregulation is central to the pathogenesis of acute Plasmodium falciparum infection. It has been assumed that this dysregulation resolves rapidly after treatment, but this return to normality has been neither demonstrated nor quantified. We therefore measured a panel of plasma endothelial markers acutely and in convalescence in Malawian children with uncomplicated or cerebral malaria. Evidence of persistent endothelial activation and inflammation, indicated by increased plasma levels of soluble intracellular adhesion molecule 1, angiopoetin 2, and C-reactive protein, were observed at 1 month follow-up visits. These vascular changes may represent a previously unrecognized contributor to ongoing malaria-associated morbidity and mortality.
内皮功能失调是急性恶性疟原虫感染发病机制的核心。人们曾认为这种失调在治疗后会迅速得到解决,但这种正常状态的恢复既没有得到证明也没有被量化。因此,我们在马拉维患有无并发症或脑型疟疾的儿童中,对一组血浆内皮标志物进行了急性和恢复期测量。在 1 个月的随访中观察到,可溶性细胞内黏附分子 1、血管生成素 2 和 C 反应蛋白等血浆水平升高,表明持续的内皮激活和炎症。这些血管变化可能是导致持续性疟疾相关发病率和死亡率的一个以前未被认识的因素。
