Idiopathic pulmonary fibrosis (IPF) is a progressive fibrosing lung disorder characterized by progressive dyspnea, exercise intolerance and, ultimately, respiratory failure and death. The incidence of IPF seems to be increasing, whereas its etiology remains unelucidated. Agents capable of modulating inflammation, kinase pathways, vascular tone, coagulation and fibrosis have been tested in clinical studies although not always in large, randomized, placebo-controlled prospective trials. Despite this effort, a therapy capable of improving survival remains elusive. Consequently, the management of IPF focuses on the early identification of subjects for lung transplantation and on the treatment of comorbidities such as hypoxemia, cough and deconditioning. Until effective therapies are identified, patients and referring physicians are urged to consider participation in well-designed clinical trials.
