Background: Idiopathic inflammatory myopathies (IIMs) are heterogeneous autoimmune diseases with variable long-term outcomes.
Objective: To determine the prognosis of IIM.
Methods: This multicenter, prospective cohort study included Chinese patients with IIM.

Background: Idiopathic inflammatory myositis (IIM) frequently coexists with interstitial lung disease (ILD), significantly impacting morbidity and mortality. Spontaneous pneumomediastinum, a complication of myositis-associated ILD, remains understudied regarding its clinical implications.
Method: We retrospectively reviewed patients diagnosed with myositis-associated ILD at Asan Medical Center, Seoul, South Korea, from April 2012 to September 2023.

Introduction: Anti-aminoacyl tRNA synthetase (anti-ARS) antibody is the most common myositis-specific antibody subtype. Anti-ARS antibody-positive myositis is often complicated by interstitial lung disease (ILD), but the clinical progression of anti-ARS antibody-positive ILD (ARS-ILD) remains unclear.
Method: A prospectively collected, single center longitudinal myositis database was used to retrospectively investigate 131 patients with ARS-ILD based on subtypes of anti-ARS antibodies (Jo-1, PL-7, PL-12, EJ, OJ, and KS).

Objectives: We aimed to assess the incidence of cancer-associated myositis among patients with anti-synthetase syndrome, identify factors associated with cancer-associated myositis, and assess its impact on prognosis.
Methods: We conducted a retrospective multicenter study, including adult patients with anti-synthetase syndrome. Factors associated with cancer were assessed using a multivariable logistic regression model.

Objectives: To investigate mortality, patient-reported outcomes (PROs), and drug-free remission (DFR) in a large well-characterised cohort of idiopathic inflammatory myopathies (IIMs).
Methods: This study retrospectively enrolled 1854 patients with IIMs. Follow-up lasted up to 20 years.
