Anti-melanoma differentiation-associated gene 5 (MDA5) antibody is associated with clinically amyopathic dermatomyositis (CADM) with rapidly progressive interstitial lung disease (RP-ILD). Recently, several studies have reported that tofacitinib (TOF), a Janus kinase inhibitor, might be effective for cases of new or refractory RP-ILD in anti-MDA5 antibody-positive CADM; however, it is unknown whether TOF can also be effective for relapsed cases. We herein report a relapsed case of RP-ILD in anti-MDA5 antibody-positive CADM, which was successfully treated by combination therapy with TOF (5 mg twice daily). Our case suggests that TOF may also be a potential treatment option for relapsed cases of this disease.
抗黑色素瘤分化相关基因5（MDA5）抗体与伴有快速进展性间质性肺病（RP-ILD）的临床无肌病性皮肌炎（CADM）相关。最近，几项研究报告称，Janus激酶抑制剂托法替布（TOF）可能对抗MDA5抗体阳性CADM的新发或难治性RP-ILD病例有效；然而，TOF对复发病例是否也有效尚不清楚。我们在此报告1例抗MDA5抗体阳性CADM的RP-ILD复发病例，该病例通过TOF（每日2次，每次5 mg）联合治疗成功治愈。我们的病例表明，TOF可能也是该疾病复发病例的一种潜在治疗选择。
