Dermatomyositis (DM) is an autoimmune myopathy with characteristic dermatologic features.1 Tofacitinib is an immunomodulator with proven efficacy against numerous immune-mediated disorders, including rheumatoid arthritis (RA) and psoriasis.2 Several reports have demonstrated oral tofacitinib’s ability to treat the cutaneous and extracutaneous manifestations of refractory dermatomyositis (DM).1,4,5 However, evidence for sustained improvement remains limited.2,3 The goal of this study is to investigate the long-term response of recalcitrant DM to oral and topical tofacitinib at varied dosing regimens.

Dermatomyositis is an idiopathic inflammatory myopathy which can present with distinctive skin features.

Background: Currently, no established integrated treatment regimen exists for anti-melanoma differentiation-associated gene 5 (anti-MDA5)-positive juvenile dermatomyositis (JDM) complicated by rapidly progressive interstitial lung disease (RP-ILD). We present a case of refractory anti-MDA5-positive JDM with RP-ILD that was successfully treated using a combination of tocilizumab and plasma exchange, along with a review of the relevant literature.
Methods: A literature review was conducted to gain insights into the clinical features and treatment strategies for managing refractory anti-MDA5-positive JDM complicated by RP-ILD.

The skin ulcers sometimes appear in patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM), and usually associates with disease activity. Here, we report a case of 41-year-old woman with anti-MDA5 antibody-positive DM, who developed refractory skin ulcers during the remission induction therapy, which were proven to be associated with clinically silent Staphylococcus aureus bacteremia with septic thrombi in her lung. The patient was referred to our hospital for the treatment of amyopathic DM with interstitial lung disease.
