Abstract

Malaria-associated acute respiratory distress syndrome (MA-ARDS) is increasingly gaining recognition as a severe malaria complication because of poor prognostic outcomes, high lethality rate, and limited therapeutic interventions. Unfortunately, invasive clinical studies are challenging to conduct and yields insufficient mechanistic insights. These limitations have led to the development of suitable MA-ARDS experimental mouse models. In patients and mice, MA-ARDS is characterized by edematous lung, along with marked infiltration of inflammatory cells and damage of the alveolar-capillary barriers. Although, the pathogenic pathways have yet to be fully understood, the use of different experimental mouse models is fundamental in the identification of mediators of pulmonary vascular damage. In this review, we discuss the current knowledge on endothelial activation, leukocyte recruitment, leukocyte induced-endothelial dysfunction, and other important findings, to better understand the pathogenesis pathways leading to endothelial pulmonary barrier lesions and increased vascular permeability. We also discuss how the advances in imaging techniques can contribute to a better understanding of the lung lesions induced during MA-ARDS, and how it could aid to monitor MA-ARDS severity.

摘要

疟疾相关的急性呼吸窘迫综合征(MA-ARDS)由于预后不良、致死率高和治疗干预有限,越来越被认为是一种严重的疟疾并发症。不幸的是,侵袭性临床研究难以进行,并且产生的机制见解有限。这些限制导致了合适的 MA-ARDS 实验小鼠模型的发展。在患者和小鼠中,MA-ARDS 的特征是肺部水肿,以及炎症细胞的明显浸润和肺泡毛细血管屏障的损伤。尽管发病途径尚未完全了解,但使用不同的实验小鼠模型对于鉴定肺血管损伤的介质至关重要。在这篇综述中,我们讨论了目前关于内皮细胞激活、白细胞募集、白细胞诱导的内皮功能障碍以及其他重要发现的知识,以更好地了解导致内皮肺屏障损伤和血管通透性增加的发病途径。我们还讨论了成像技术的进步如何有助于更好地理解 MA-ARDS 期间诱导的肺部病变,以及如何帮助监测 MA-ARDS 的严重程度。
