Acute kidney injury (AKI) is a common feature of severe malaria, and an independent risk factor for death. Previous research has suggested that an overactivation of the host inflammatory response is at least partly involved in mediating the kidney damage observed in patients with AKI, however the exact pathophysiology of AKI in severe malaria remains unknown. The purpose of this mini-review is to describe how different aspects of malaria pathology, including parasite sequestration, microvascular obstruction and extensive intravascular hemolysis, may interact with each other and contribute to the development of AKI in severe malaria, by amplifying the damaging effects of the host inflammatory response. Here, we highlight the importance of considering how the systemic effects and multi-organ involvement of malaria are intertwined with the localized effects on the kidney.
急性肾损伤(AKI)是严重疟疾的常见特征,也是死亡的独立危险因素。既往研究提示,宿主炎症反应的过度激活至少部分参与介导 AKI 患者的肾脏损伤,然而严重疟疾 AKI 的具体病理生理学机制仍不清楚。本篇综述的目的在于描述疟疾发病机制的不同方面,包括寄生虫黏附、微血管阻塞和广泛的血管内溶血,如何通过放大宿主炎症反应的损伤作用,相互作用并导致严重疟疾 AKI 的发生。在此,我们强调考虑疟疾的全身效应和多器官受累与肾脏局部效应相互交织的重要性。
