Factor X deficiency is the most common coagulation factor deficiency amongst patients with AL amyloidosis. It presumably occurs due to adsorption of factor X to amyloid fibrils. The deficiency of this factor, in conjunction with other hemostatic defects, can cause bleeding complications. A case of acquired factor X deficiency due to AL amyloidosis is reported, where abnormal coagulation parameters were the only presenting feature.
因子 X 缺乏症是 AL 淀粉样变性患者中最常见的凝血因子缺乏症。它可能是由于因子 X 吸附到淀粉样纤维上而发生的。这种因子的缺乏,加上其他止血缺陷,可能导致出血并发症。报告了一例由 AL 淀粉样变性引起的获得性因子 X 缺乏症,其中异常的凝血参数是唯一的表现特征。
