Abstract Objective To explore the level and significance of serum hyaluronic acid (HA) and laminin (LN) in patients with idiopathic pulmonary fibrosis (IPF). Methods From June 2014 to June 2016 , in Department of Respiratory Diseases, Affiliated Hospital of Hangzhou Normal University, 38 patients with IPF were selected as control group, and 30 healthy persons without smoking at same time were selected as control group. The levels of serum HA and LN in IPF patients and cotrol group were detected by radioimmunoassay. And the correlation between serum HA, LN with lung function, 6-minute walk test (6MWT) and dyspnea score was evaluated. Results Compared with the control group, the levels of serum HA and LN of patients in IPF group were significantly higher (P < 0.05). The levels of serum HA and LN in patients with IPF were negatively correlated with FVC, FEV1 and DLCO (all r < 0, P < 0.05 or P < 0.01); HA and LN were negatively correlated with 6MWT (r = -0.637, -0.705, P < 0.01); the levels of serum HA and LN in IPF patients were positively correlated with mMRC score (r = 0.618, 0.552, P < 0.05). Conclusion These data suggest that serum HA and LN may be useful biomarkers to estimate the severity and treatment effect of patients with IPF.
