Ann Rheum Dis:巨细胞动脉炎的一种新型超声光晕评分

2020-01-05 xiangting MedSci原创

超声光晕评分可以量化GCA的血管炎症程度。超声上广泛的血管炎症可以强有力的确认GCA诊断,并与眼部缺血相关。

颞动脉及腋动脉的超声检查可以发现巨细胞动脉炎(GCA)患者的血管壁炎症。这里开发了一种超声评分系统以量化血管炎症的程度,并研究了其诊断准确性以及与GCA临床因素的相关性。

这是一项前瞻性研究,纳入89名疑诊GCA患者,其中58名在随访6个月后被临床确诊为GCA。在颞动脉(TA)活检之前,所有患者均接受了三个TA节段和腋动脉的双侧超声检查。血管炎症的程度可通过以下方法量化:(1)计算带有光晕的TA节段和腋动脉的数量,和(2)计算还包括每个光晕厚度的综合光晕评分。

光晕计数和光晕评分对GCA的临床诊断具有中等诊断准确性。其与全身性炎症呈正相关。与光晕计数比较,光晕评分与C反应蛋白(CRP)水平的相关性更好,并可以确定更多患者的GCA诊断。光晕计数和光晕评分较高与眼部缺血风险较高相关。该评分可以确定眼部缺血的低风险(≤5%)和高风险(>30%)患者亚组。

超声光晕评分可以量化GCA的血管炎症程度。超声上广泛的血管炎症可以强有力的确认GCA诊断,并与眼部缺血相关。
