Severe hepatic failure is rarely a cause of death in patients with immunoglobulin light chain (AL) amyloidosis. We herein report a case of AL amyloidosis involving a bleeding tendency due to factor X deficiency and marked hepatic involvement of amyloidosis. The patient died due to severe liver dysfunction two weeks after admission. The diagnosis was confirmed histologically by AL-λ amyloidosis, with the liver and spleen as the main lesions, on an autopsy. As treatment-related toxicity is strong in advanced cases, appropriate treatments are required to improve the prognosis of AL amyloidosis with severe liver dysfunction.
严重肝衰竭在免疫球蛋白轻链(AL)淀粉样变性患者中很少是死亡原因。我们在此报告一例AL淀粉样变性病例,该患者因X因子缺乏而有出血倾向,且淀粉样变性有明显肝脏受累。患者入院两周后因严重肝功能障碍死亡。尸检组织学检查证实诊断为AL-λ淀粉样变性,以肝脏和脾脏为主要病变部位。由于晚期病例中与治疗相关的毒性很强,因此需要采取适当治疗以改善伴有严重肝功能障碍的AL淀粉样变性患者的预后。
