This document is an international evidence-based guideline on the diagnosis and management of idiopathic pulmonary fibrosis, and is a collaborative effort of the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association. It represents the current state of knowledge regarding(More)
BACKGROUND In 2002 the American Thoracic Society/European Respiratory Society (ATS/ERS) classification of idiopathic interstitial pneumonias (IIPs) defined seven specific entities, and provided standardized terminology and diagnostic criteria. In addition, the historical "gold standard" of histologic diagnosis was replaced by a multidisciplinary approach.(More)
Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease without proven effective therapy. A multicentre, double-blind, placebo-controlled, randomised phase III clinical trial was conducted in Japanese patients with well-defined IPF to determine the efficacy and safety of pirfenidone, a novel antifibrotic oral agent, over 52 weeks. Of 275 patients(More)
BACKGROUND Idiopathic pulmonary fibrosis is a progressive lung disease with a high mortality rate. Because the signaling pathways activated by several tyrosine kinase receptors have been shown to be involved in lung fibrosis, it has been suggested that the inhibition of these receptors may slow the progression of idiopathic pulmonary fibrosis. METHODS In(More)
Idiopathic pulmonary fibrosis (IPF) is an adult-onset, lethal, scarring lung disease of unknown etiology. Some individuals with IPF have a familial disorder that segregates as a dominant trait with incomplete penetrance. Here we used linkage to map the disease gene in two families to chromosome 5. Sequencing a candidate gene within the interval, TERT,(More)
RATIONALE Idiopathic pulmonary fibrosis is a chronic interstitial lung disease of unknown etiology; its epidemiology in the United States has not been well characterized. OBJECTIVE To estimate the annual incidence and prevalence of idiopathic pulmonary fibrosis in the United States. METHODS Retrospective cohort design utilizing a large health care(More)
BACKGROUND The clinical utility of bronchoalveolar lavage fluid (BAL) cell analysis for the diagnosis and management of patients with interstitial lung disease (ILD) has been a subject of debate and controversy. The American Thoracic Society (ATS) sponsored a committee of international experts to examine all relevant literature on BAL in ILD and provide(More)
STUDY OBJECTIVES Health-related quality of life associated with interstitial lung disease has received little attention in clinical studies because there have been no validated methods for directly measuring it. We have assessed the validity of several generic and respiratory-specific quality-of-life instruments in patients with interstitial lung disease.(More)
Idiopathic pulmonary fibrosis (IPF) is a progressive clinical syndrome of unknown etiology and fatal outcome. Currently available therapies are ineffective and associated with significant adverse effects. Pirfenidone, a new, investigational antifibrotic agent, was evaluated for its tolerability and usefulness in terminally ill patients with advanced IPF.(More)
RATIONALE The 2002 American Thoracic Society/European Respiratory Society classification of idiopathic interstitial pneumonias identified nonspecific interstitial pneumonia (NSIP) as a provisional diagnosis. Concern was expressed that NSIP was a "wastebasket" category, difficult to distinguish from other idiopathic interstitial pneumonias. OBJECTIVES The(More)
