【 摘 要 】

Objective: Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia with unknown cause. We analyzed the changed rate of pulmonary function and arterial blood gas in IPF patients, and evaluated their influence of changed rate to IPF prognosis. Methods: 81 patients with IPF were recruited successfully, they were followed-up at 6 and 12 months. Dyspnea score and respiratory assessment parameters including FVC, FEV₁, TLC, SaO₂, P_A-aO₂, and D_LCO were evaluated at their 6 and 12 months follow-up. The changed value and changed rate of above parameters were calculated, and their treatment effects were divided into 3 subgroup: improved, stable and deteriorated group. Statistical analysis was performed between groups for survival and hazards regression analysis. Results: 55 of 81 patients were follow-up at 12 months. Dyspnea score and its changed rate, the changed value of FEV₁%, FVC%, TLC%, D_LCO%, and PaO₂, SaO₂, P_A-aO₂ were prognosis effect factors in IPF patients in 6 and 12 months group. The survival analysis of dyspnea scores, FVC%, TLC%, D_LCO%, PaO₂, SaO₂ and P_A-aO₂ at K-M were all statistical significant (P < 0.05) in improved, stable and deteriorated group. Conclusion: FVC% changed rate, dyspnea score changed rate and PaO₂ changed rate were IPF patient prognosis associated factors in 6 months group; and FVC% changed rate, D_LCO% changed rate and TLC% changed rate were prognosis associated factors for IPF patient in 12 months group.
