A prospective and longitudinal study to investigate the correlations between Krebs von den Lungen-6 (KL-6) serum levels and systemic sclerosis associated with interstitial lung disease (SSc-ILD). ⋯ Serum KL-6 level correlates with the clinical manifestations of microvascular injury. Baseline elevated serum KL-6 may predict deterioration of lung function of SSc-ILD patients with mild lung injury.
