Comprehensive review uncovers distinct prognostic profiles in inflammatory myopathy-associated lung disease, highlighting the need for prompt subtype diagnosis to prevent fatal outcomes.
Interstitial lung disease (ILD) is a frequent manifestation and a leading cause of morbidity and mortality in idiopathic inflammatory myopathies (IIM), particularly in antisynthetase syndrome (ASyS) and anti-melanoma differentiation-associated protein 5 (MDA5) dermatomyositis. Although these disorders share common features of interstitial lung diseases, they differ substantially in pathogenesis, clinical phenotype, prognosis, and therapeutic response. There is also variability amongst the different subtypes of IIM-ILD. Recognition of these distinctions is essential for accurate diagnosis and treatment; delays in care, especially in cases of rapidly progressive ILD (RP-ILD), can be associated with high mortality. This review focuses on ILD in IIM, focusing on ASyS and anti-MDA5 dermatomyositis, highlighting similarities and key differences in disease mechanisms, clinical presentation, diagnostic evaluation, prognostic biomarkers, and management strategies.
