Correlation of serum Krebs von den Lungen-6 levels with fibrosis score on high resolution chest tomography and pulmonary function parameters in treatment naïve Idiopathic Pulmonary Fibrosis.

While serum Krebs von den Lungen-6 (KL-6) has been found to be a helpful biomarker in interstitial lung diseases for evaluating disease severity and progression, especially in connective tissue disease-associated interstitial lung disease (CTD ILD) and idiopathic non-specific interstitial pneumonia (NSIP), data on correlation of serum KL-6 levels with radiological fibrosis and pulmonary function parameters is lacking in treatment naïve Idiopathic Pulmonary Fibrosis (IPF) patients.
