广泛存在于多种自身免疫性疾病中,包括原性胆汁性胆管炎、自身免疫性肌病(皮肌炎)以及其他炎症(34)

床疑似原性胆汁性胆管炎的患者,建续检测抗Sp100(以及PML/Sp140)抗体;特别是抗Sp100抗体与原性胆汁性胆管炎的床相关性最佳,尤其是与AMA检测时检测结具有附加价Sp100(和PML/Sp140)抗原包含在疾病特异性免疫检测(例如,肝病*)中(17,35,36)

►对于临床疑似皮肌炎的患者,建议后续检测抗MJ/NXP-2抗体;抗MJ/NXP-2抗体对于自身免疫性肌病具有高度特异性,在多达三分之一的皮肌炎少年患者中发现,并且据报道与成人自身免疫性肌病患者的恶性肿瘤相关;该抗原包含在疾病特异性免疫检测中(例如,炎症性肌病谱*)(37-39)

*炎症性肌病谱、系统性硬化症谱和(扩展的)肝病谱的应用可能仅限于专业的临床实验室。

► Found in a broad spectrum of autoimmune diseases, including PBC, AIM (DM), as well as other inflammatory conditions (34)

► If PBC is clinically suspected, it is recommended to perform follow-up tests for anti-Sp100 (and PML/Sp140) antibodies; in particular anti-Sp100 antibodies have the best clinical association with PBC and have added value, especially when associated with AMA; the Sp100 (and PML-Sp140) antigen is included in disease specific immunoassays (i.e., liver profile*) (17, 35, 36)

► If DM is clinically suspected, it is recommended to perform a follow-up test for anti-MJ/NXP-2 antibodies; these anti-MJ/NXP-2 antibodies are highly specific for AIM, are found in up to one third of patients with juvenile DM, and have been reported to be associated with malignancies in adult AIM patients; the antigen is included in disease specific immunoassays (i.e., inflammatory myopathy profile*) (37–39)

*Availability of the inflammatory myopathy profile, the SSc profile and the (extended) liver profile may be limited to specialty clinical laboratories.
