Idiopathic Pulmonary Fibrosis
Understanding Idiopathic Pulmonary Fibrosis (IPF)
IPF is a form of progressive pulmonary fibrosis, or abnormal scarring of the lungs. As the scarring progresses, transfer of oxygen into the bloodstream is increasingly impaired, leading to irreversible loss of lung function as well as high morbidity and mortality rates. Average life expectancy is estimated to be three to five years from diagnosis, with approximately two-thirds of patients dying within five years of diagnosis. Survival rates are comparable to those for some of the deadliest cancers.
IPF is designated as an orphan disease in the U.S., with U.S. prevalence and incidence of IPF estimated to be 200,000 cases (for IPF defined based on ICD-9 code) and 50,000 new cases per year , respectively. Incident and mortality are on the rise, and prevalence is expected to increase with the aging population.
