Diagnostic value of KL-6 in idiopathic interstitial pneumonia %K %X Background: Idiopathic interstitial pneumonia (IIP) can induce type II alveolar epithelial cell proliferation and pulmonary basement membrane damage and subsequent release of Krebs von den Lungen-6 antigen (KL-6) to the bloodstream. This study investigated the diagnostic and prognostic value of serum KL-6 levels for IIP. Methods: One hundred five patients with lung disease were divided into IIP (n=75) and non-IIP groups (n=30) according to pathological and computed tomography findings. Serum KL-6 levels were evaluated in blood samples from all subjects. Nineteen IIP group patients were also subjected to a longitudinal study of disease progression and serum KL-6 levels over time. Results: Serum KL-6 levels were significantly higher in the IIP group vs. the non-IIP group [1,096.0 (565.0–1,544.0) vs. 226.0 (173.5–346.5) U/mL; P %U https://jtd.amegroups.org/article/view/22915 %V 10 %N 8 %P 4724-4732 %@ 2077-6624
