We report hereby a severe case of Hantavirus Pulmonary Syndrome" (HPS) induced by Maripa virus in French Guiana and describe the mechanism of severity of the human disease.
A 47-year- old patient started presenting a prodromic period with fever, dyspnea, cough and head ache. This clinical presentation was followed by a rapid respiratory, hemodynamic and renal failure leading to admission in the ICU. Biological exams revealed an increased haematocrit level with a paradoxical low protein level. Echocardiographic and hemodynamic monitoring showed a normal left ventricular function with low filling pressures, an elevated extravascular lung water index and pulmonary vascular permeability index. These findings were compatible with a capillary leak-syndrome (CLS).
The severity of HPS caused by the virus Maripa in French Guiana can be explained by the tropism of hantavirus for the microvascular endothelial cell leading to a CLS.
我们报告了法属圭亚那马拉巴病毒引起的严重汉坦病毒肺综合征（HPS）病例，并描述了人类疾病严重程度的机制。
一名 47 岁患者开始出现发热、呼吸困难、咳嗽和头痛的前驱期。随后出现快速呼吸、血流动力学和肾功能衰竭，导致入住 ICU。生物学检查显示血细胞比容水平升高，而蛋白水平反常降低。超声心动图和血流动力学监测显示左心室功能正常，充盈压低，肺血管外水指数和肺血管通透性指数升高。这些发现与毛细血管渗漏综合征（CLS）相符。
法属圭亚那马拉巴病毒引起的 HPS 严重程度可归因于汉坦病毒对微血管内皮细胞的嗜性，导致 CLS。
