基于受累器官的专门检查
●心脏
►ECG
►应变超声心动图
►心脏MRI(在某些情况下)
●肝脏和胃肠道
►大便潜血
►胃排空扫描(如果存在胃轻瘫)
►超声或CT扫描

●其它
►内分泌检查:促甲状腺激素(TSH),皮质醇
►肺部检查:肺功能测试
注解
a.如果不能查NT-proBNP,可查BNP。
b.必需确认患者是原发性全身性淀粉样变性,而不是遗传性淀粉样变性、老年性淀粉样变性或继发性淀粉样变性。 应使用免疫组织化学或质谱法确认淀粉样沉积物由轻链组成。 如果κ和λ染色为阴性,应进行转甲状腺素蛋白或血清淀粉样蛋白A的免疫组化检查。
c.鉴定血清或尿液中的轻链而不确认组织中的淀粉样蛋白组成是不够的,因为具有其他形式的淀粉样变性的患者可能具有不相关的单克隆丙种球蛋白病(MGUS)。Lachmann HJ, Booth DR, Booth SE, et al. Misdiagnosis of hereditary amyloidosis as AL (primary) amyloidosis. N Engl J Med 2002;346:1786-1791.
d.刚果红对淀粉样变染色,但 刚果染色不区分淀粉样蛋白的类型。
临床结果和初始治疗 (AMYL-2)
e.参见基于淀粉样变性共识标准的器官受侵定义 (AMYL-B)和器官和血液学缓解和进展标准的定义(AMYL-C)。
f.用硼替佐米治疗的患者推荐预防带状疱疹。
g.作为干细胞移植一部分的美法仑的剂量可以基于诸如年龄、心脏受累与否以及受累器官的数目等因素进行调整。这些风险调整的方法在随机研究中没有评估。
