  • ►AC-24核型对任何疾病的阳性预测价值都很低

    ►在系统性自身免疫性风湿疾病谱内，AC-24核型在雷诺现象、局限型硬皮症、系统性硬化症、系统性红斑狼疮和类风湿性关节炎中或被单独检出或与其他系统性硬化症关联的抗体一起被联合检出 (102-105)

    ►所识别的抗原包括α-烯醇化酶、γ-烯醇化酶、ninein、Cep-250、Mob1、PCM-1 / 2、中心粒周蛋白；这些自体抗体的特异性免疫检测试剂目前尚未商品化 (104，106-108)



    ► The AC-24 pattern has low positive predictive value for any disease

    ► Within the spectrum of the SARD, the AC-24 pattern is found in patients with Raynaud’s phenomenon, localized scleroderma, SSc, SLE and RA, either alone or in combination with other SSc-associated antibodies (102–105)

    ► Antigens recognized include α-enolase, γ-enolase, ninein, Cep-250, Mob1, PCM-1/2, pericentrin; specific immunoassays for these autoantibodies are currently not commercially available (104, 106–108)

    Second level information

  • ►可能与感染相关联；在肺炎支原体感染患儿的病例中有报道 (1)

    ►可能与恶性肿瘤相关联；在乳腺癌患者血清中经常发现与中心体的抗原反应的自身抗体 (2,3)

    ►据报道，在水痘感染后的小脑共济失调患儿中检出针对α-烯醇化酶、γ-烯醇化酶、Mob1、PCM-1/2和中心粒周蛋白的自身抗体；一例甲状腺功能亢进和肌肉隐痛患者与一例雷诺现象患者，两者均无系统性自身免疫性风湿疾病，但具有α-烯醇化酶和γ-烯醇化酶抗体 (4,5)

    ►对于ninein和Cep-250的自身抗体，血清自身抗体反应与临床诊断之间无显著相关性；在类风湿性关节炎和系统性红斑狼疮中检出 (6,7)

    注：大多数报道都描述了自身抗体直接与特异性抗原结合 (即，抗原特异性免疫检测法)，实际并未显示与AC-24模式相关性；这些自身抗体的特异性免疫检测试剂目前尚未商品化


    ► Possible association with infections; described in children with Mycoplasma pneumoniae infection (1)

    ► Possible association with malignancies; autoantibodies reacting with antigens in centrosomes are frequently found in sera of patients with breast cancer (2, 3)

    ► Autoantibodies to α-enolase, γ-enolase, Mob1, PCM-1/2, and pericentrin have been described in children with cerebellar ataxia after varicella infection; one patient with hyperthyroidism and vague muscle pain and one patient with Raynaud’s phenomenon, both without evidence of a SARD, had antibodies to α-enolase and γ-enolase (4.5)

    ► With respect to autoantibodies to ninein and Cep-250, there is no apparent correlation between serum autoantibody reactivity and the clinical diagnosis; reported in RA and SLE (6, 7)

    Notes: Most reports describe autoantibodies directly binding to specific antigens (i.e., antigen-specific immunoassays) and do not actually show correlations with the AC-24 pattern as such; specific immunoassays for these autoantibodies are currently not commercially available.
