Nailfold videocapillaroscopy findings correlate with lung outcomes in idiopathic inflammatory myopathies-related interstitial lung disease

Idiopathic inflammatory myopathies (IIM) are a diverse group of muscle diseases often complicated by interstitial lung disease (ILD), which significantly impacts morbidity and mortality. Krebs von den Lungen-6 (sKL-6) has been proposed as a biomarker for ILD severity. Nailfold videocapillaroscopy (NVC) detects microvascular changes, but its diagnostic and prognostic value in IIM remains unclear. This study aimed to assess the relationship between NVC abnormalities, sKL-6 levels, and pulmonary outcomes in IIM patients.
