Abstract

Anti-melanoma differentiation-associated gene 5 (MDA5) antibodies are frequently detected in amyopathic dermatomyositis with rapidly progressive interstitial lung disease (RP-ILD). However, the presence of anti-MDA5 antibodies in other connective tissue diseases is not well known. We herein report a case of rheumatoid arthritis complicated with refractory anti-MDA5 antibody-positive ILD. A 75-year-old Japanese woman was referred to our hospital for refractory ILD. Serological testing was positive for anti-MDA5 antibody without any muscle or skin lesions. Immunosuppressive therapy (prednisolone and tacrolimus) ameliorated her symptoms as well as ILD. Anti-MDA5 antibody-positive ILD, as well as dermatomyositis with RP-ILD, can occur in patients with rheumatoid arthritis.

摘要

抗黑色素瘤分化相关基因5(MDA5)抗体在伴有快速进展性间质性肺病(RP-ILD)的无肌病性皮肌炎中经常被检测到。然而,抗MDA5抗体在其他结缔组织疾病中的存在情况尚不清楚。我们在此报告一例类风湿关节炎合并难治性抗MDA5抗体阳性ILD的病例。一名75岁的日本女性因难治性ILD转诊至我院。血清学检测显示抗MDA5抗体呈阳性,且无任何肌肉或皮肤病变。免疫抑制治疗(泼尼松龙和他克莫司)改善了她的症状以及ILD。抗MDA5抗体阳性ILD以及伴有RP-ILD的皮肌炎可发生于类风湿关节炎患者中。
