摘要:肌炎抗体分为肌炎特异性自身抗体(MSA)和肌炎相关性自身抗体(MAA)。不同肌炎抗体在间质性肺病(ILD)中的作用机制、临床特点及预后等方面存在异质性。在MSA中,抗黑色素瘤分化相关基因5(MDA5)抗体和抗氨酰tRNA合成酶(ARS)抗体与ILD的发生高度相关。抗MDA5抗体阳性皮肌炎(DM)患者ILD的发生率高,进展迅速,预后较差。抗ARS抗体阳性DM患者ILD的病程缓慢,对治疗反应较好,但易复发。在MAA中,抗Ro52抗体通常与MSA抗体共存,临床表现与共存抗体关系密切。就肌炎自身抗体在ILD中的研究进展进行综述。

Abstract: Myositis antibodies are divided into myositis-specific autoantibodies (MSA) and myositis-associated autoantibodies (MAA). There are heterogeneity in the mechanism, clinical features and prognosis of interstitial lung disease (ILD) in the different myositis antibodies. In MSA, anti-melanoma differentiation-related gene 5 (MDA5) antibody and anti-aminoacyl synthetase (ARS) antibody are highly correlated with the occurrence of ILD. Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis. The progress of ILD in ARS+ DM patients was slow, and the response to treatment is good, but it is easy to relapse. In MAA, anti-Ro52 antibodies often coexist with MSA antibodies, and clinical manifestation is closely related to coexisting antibodies. This review has summarized roles of myositis antibodies in ILD.

皮肌炎(dermatomyositis,DM)是一类主要累及横纹肌的弥漫性炎症性肌病[1]。DM自身抗体分为肌炎特异性自身抗体(myositis-specific antibodies,MSA)和肌炎相关性自身抗体(myositis-associated antibodies,MAA),其中MSA主要有抗黑色素瘤分化相关基因5(anti-melanoma differentiation-related gene 5,MDA5)抗体、抗氨酰tRNA合成酶(anti-aminoacyl synthetase,ARS)抗体、抗小泛素样修饰物激活酶(small ubiquitin-like modifier activating enzyme,SAE)抗体、抗转录中介因子1γ(transcriptional intermediary factorl,TIF1-γ)抗体、抗核基质蛋白2(anti-nuclear matrix protein 2,NXP2)抗体和抗Mi-2抗体;MAA主要有抗Ro52抗体、抗Ku抗体、抗SSA/Ro60抗体、抗多发性肌炎/硬皮病复合物(PM/Scl)抗体和抗U1核糖核蛋白(anti-U1 ribonucleoprotein antibodies,U1RNP)抗体。不同自身抗体的DM患者临床表现不同,DM患者多合并间质性肺病(interstitial lung disease,ILD)。不同肌炎抗体患者ILD特点不同,如抗MDA5抗体阳性患者出……
