Anti-synthetase syndrome (AS) is a rare autoimmune disorder characterized by the presence of aminoacyl-transfer RNA synthetase antibodies in conjunction with clinical features such as interstitial lung disease (ILD), Raynaud's phenomenon, nonerosive arthritis, and myopathy. AS distinguishes itself from other inflammatory myopathies by its significant lung involvement and rapidly progressive interstitial lung disease (AS-ILD), therefore the management of AS-ILD requires careful clinical, serologic and radiologic assessment. Glucocorticoids are considered the mainstay of therapy; however, additional immunosuppressive agents are often required to achieve disease control. Patient prognosis is highly dependent on early diagnosis and symptom recognition as the antibody profile is thought to influence therapy response. Since progressive ILD is the leading cause of morbidity and mortality, this review will discuss the clinical approach to patient with suspected AS, with particular emphasis on diagnosis and management of AS-ILD.
抗合成酶综合征(AS)是一种罕见的自身免疫性疾病,其特征是存在氨酰 - 转运RNA合成酶抗体,并伴有间质性肺病(ILD)、雷诺现象、非侵蚀性关节炎和肌病等临床特征。AS因其显著的肺部受累和快速进展的间质性肺病(AS - ILD)而有别于其他炎性肌病,因此,AS - ILD的管理需要仔细的临床、血清学和放射学评估。糖皮质激素被认为是主要的治疗药物;然而,通常还需要额外的免疫抑制剂来控制疾病。患者的预后高度依赖于早期诊断和症状识别,因为抗体谱被认为会影响治疗反应。由于进行性ILD是发病和死亡的主要原因,本综述将讨论疑似AS患者的临床处理方法,特别强调AS - ILD的诊断和管理。
