Introduction: Dermatomyositis (DM) is characterized by skin lesions, such as heliotrope rash and Gottron's papules/sign, and skeletal myopathy. Patients with DM often have arthritis, cardiomyopathy, interstitial lung disease (ILD), and concomitant malignancy. Since clinical characteristics, treatment response, and prognosis are highly variable among patients, it is critical to predict future outcomes in DM patients before the initiation of management. Recently, a number of myositis-specific and -associated autoantibodies (MSAs/MAAs) have been identified and well characterized, and commercial assays for their detection have become available.Areas covered: There is accumulating evidence showing the utility of MSAs/MAAs in diagnosis of DM and in predicting clinical courses and outcomes in patients with DM as convenient biomarkers, i.e. an association of ILD with anti-ARS, anti-MDA5 and anti-SAE; and malignancy with anti-TIF1-γ, anti-NXP2, and anti-SAE in adults. This review describes available assays employed for the detection of MSAs/MAAs and how to integrate autoantibody results into clinical practice of DM patients, mainly adult patients. The relevant literature was searched on PubMed as of 2 November 2019.Expert opinion: MSAs/MAAs are convenient biomarkers that are useful in personalized medicine and thus should be adopted in routine clinical practice of patients with DM, but in a science-based manner.

在皮肌炎患者中检测到的肌炎特异性和相关自身抗体的当前理解和最新进展。

简介:皮肌炎 (DM) 的特征是皮肤病变,如天芥菜皮疹和 Gottron 丘疹/征,以及骨骼肌病。DM 患者通常有关节炎、心肌病、间质性肺病 (ILD) 和伴随的恶性肿瘤。由于患者的临床特征、治疗反应和预后差异很大,因此在开始管理之前预测 DM 患者的未来结果至关重要。最近,许多肌炎特异性和相关自身抗体 (MSA/MAA) 已被鉴定和充分表征,并且已经可以用于检测它们的商业化验。涵盖的领域:有越来越多的证据表明 MSA/MAA 在诊断中的效用DM 和预测 DM 患者的临床过程和结果作为方便的生物标志物,即 ILD 与抗 ARS、抗 MDA5 和抗 SAE 的关联;以及成人中具有抗 TIF1-γ、抗 NXP2 和抗 SAE 的恶性肿瘤。本综述描述了用于检测 MSAs/MAA 的可用检测方法,以及如何将自身抗体结果整合到 DM 患者(主要是成人患者)的临床实践中。在 PubMed 上检索了截至 2019 年 11 月 2 日的相关文献。 专家意见:MSA/MAA 是方便的生物标志物,可用于个性化医疗,因此应在 DM 患者的常规临床实践中采用,但应以科学为基础。主要是成年患者。在 PubMed 上检索了截至 2019 年 11 月 2 日的相关文献。 专家意见:MSA/MAA 是方便的生物标志物,可用于个性化医疗,因此应在 DM 患者的常规临床实践中采用,但应以科学为基础。主要是成年患者。在 PubMed 上检索了截至 2019 年 11 月 2 日的相关文献。 专家意见:MSA/MAA 是方便的生物标志物,可用于个性化医疗,因此应在 DM 患者的常规临床实践中采用,但应以科学为基础。
