Idiopathic pulmonary fibrosis
- Acute interstitial pneumonia
- Acute interstitial pneumonitis
- Cryptogenic fibrosing alveolitis
- Familial idiopathic pulmonary fibrosis
- older age at diagnosis
- extensive cigarette smoking
- lower body mass index (BMI)
- more severe physiologic impairment
- greater extent of disease on imaging studies
- the development of other complications or conditions (eg, pulmonary hypertension, emphysema, and bronchogenic cancer)
The natural history of IPF is not completely understood. While it usually follows a course of progressive deterioration, some people remain stable for extended periods and individual outcomes can vary significantly. Still, long-term survival of IPF is not expected.
It now appears that three potential disease courses exist, but there is not currently a definitive way to predict the course in an affected person. They are:
a) slowly progressive disease (the most common);
b) disease marked by episodes of acute exacerbations; and
c) rapidly progressive disease.
