Summary

Interstitial lung disease (ILD) is a common pulmonary manifestation of idiopathic inflammatory myopathy (IIM). The overall 5-year mortality is 50%. The prognosis is poor and the treatment is challenging.At present, according to the consensus of IIM-ILD experts, glucocorticoids as first-line treatment are often used in high doses and have a variety of adverse reactions. Previous studies have shown that cyclophosphamide (CYC) is effective for IIM-ILD and tends to be used in rapidly progressive interstitial lung disease（RP-ILD）or refractory ILD. However, CYC is an alkylating agent with many toxic and side effects. It is prone to gonadal inhibition, infection, tumor, hemorrhagic cystitis and other risks. At present, Mycophenolate mofetil (MMF) has been widly used in the treatment of IIM, systemic lupus erythematosus (SLE), ANCA associated vasculitis (AAV). The observational research on MMF in the treatment of IIM-ILD shows that it can delay the progress of pulmonary fibrosis and can be used as the first-line treatment of IIM-ILD. Moreover, immune tolerance caused by defects in the number and/or quality of regulatory T cells (Treg) is considered to be a key source of autoimmune diseases. However, it is unclear whether MMF can improve the immune status of IIM-ILD by increasing Treg cells. The aim of this study was to evaluate the effect of MMF for IIM-ILD and its effcts on Treg through a prospective open single arm study, and provide a theoretical basis for the individualized treatment of IIM-ILD, which has important clinical significance.
