摘要
Our understanding of idiopathic pulmonary fibrosis （IPF） has undergone major changes in recent years. IPF is the most common of the idiopathic interstitial pneumonias. It remains the most often diagnosed, accounting for 50% to 60% of all cases. It is also associated with a worse prognosis than most of the interstitial lung diseases. The number of deaths related to IPF is nearly 14 times greater than those from asbestosis, while a recent estimate has suggested prevalence in the United States ranging from 14.0 to 42.7 cases per 100 000 population, depending on the criteria used for diagnosis,
