Idiopathic pulmonary fibrosis (IPF) is one of the most common idiopathic interstitial pneumonia. The main symptoms for IPF are dry cough and exertional shortness of breath, which is worsen gradually with the development of pulmonary fibrosis. Patients with IPF often suffer from sleep disordered breathing (SDB). Sleep architecture for these patients including the sleep efficiency, deep sleep, rapid eye movement sleep and arousal index, are changed, which seriously affects the quality of life. In the absence of effective therapies, optimizing the quality of life may become a major therapeutic target for IPF...

Idiopathic Pulmonary Fibrosis (IPF) is a relentlessly progressive, fibrosing interstitial pneumonia characterized by a radiologic and/or histologic pattern of usual interstitial pneumonia (UIP). The availability of two effective anti-fibrotic drugs in IPF has encouraged the identification and treatment of patients in early stages in order to maximize clinical benefit. The ability of high-resolution computed tomography (HRCT) to identify a 'definite' UIP pattern is suboptimal, particularly in the absence of honeycombing...

BACKGROUND: Patients with hypersensitivity pneumonitis are at risk of developing pulmonary fibrosis, which is associated with reduced survival. In families with multiple affected members, individuals might be diagnosed as having idiopathic pulmonary fibrosis (IPF) or chronic (fibrotic) hypersensitivity pneumonitis, which suggests these disorders share risk factors. We aimed to test whether the genomic risk factors associated with the development and progression of IPF are also associated with the development of fibrosis and reduced survival in people with chronic hypersensitivity pneumonitis...

RATIONALE: Usual interstitial pneumonia (UIP) is the histopathologic hallmark of idiopathic pulmonary fibrosis. While UIP can be detected by high-resolution computed tomography (HRCT) of the chest, HRCT results are frequently inconclusive, and pathology from transbronchial biopsy (TBB) has poor sensitivity. Surgical lung biopsy (SLB) may be necessary for a definitive diagnosis. OBJECTIVES: To develop a genomic classifier in tissue obtained by TBB that distinguishes UIP from non-UIP, trained against central pathology as the reference standard...

The following report outlines the case of a 76-year-old gentleman who presented to the hospital with acute interstitial pneumonitis, a rare and rapidly progressive type of idiopathic interstitial pneumonia. The patient initially presented with a three-week history of progressive shortness of breath and cough which was diagnosed as community acquired pneumonia. Treatment with oral antibiotics was unsuccessful resulting in re-presentation the following week with type one respiratory failure. Investigations revealed widespread inflammatory changes consistent with an acute inflammatory process...

As an idiopathic interstitial pneumonia, desquamative interstitial pneumonia (DIP) is an uncommon form of interstitial lung disease and is considered to be a smoking- or dust inhalation-related interstitial pneumonia in the majority of cases. However, the details regarding immunoglobulin G4 (IgG4)-related lung disease remain unclear and controversial. We herein report the first case of DIP complicated with IgG4-related lung disease. Even if a patient has a smoking history, we emphasize the importance of exploring the association between DIP and IgG4-related lung disease to clarify the pathogenesis of these two disorders...

PURPOSE OF REVIEW: Therapeutic advances in the management of idiopathic pulmonary fibrosis (IPF) has led to improved outcomes with the use of the antifibrotic agents pirfenidone and nintedanib, with a number of randomized studies demonstrating benefits in slowing disease progression in IPF. However, treatment of other fibrosing interstitial lung diseases (ILD) remains challenging. RECENT FINDINGS: Observational and uncontrolled studies investigating pirfenidone and nintedanib in non-IPF ILDs suggest potential benefits, although the data is weak...

The diagnosis of hypersensitivity pneumonitis (HP) relies on the clinical evaluation of a number of features, including a history of significant exposure to potentially causative antigens, physical examination, chest CT scan appearances, bronchoalveolar lavage lymphocytosis, and, in selected cases, histology. The presence of fibrosis is associated with higher morbidity and mortality. Differentiating fibrotic HP from the idiopathic interstitial pneumonias can be a challenge. Furthermore, even in the context of a clear diagnosis of fibrotic HP, the disease behaviour can parallel that of idiopathic pulmonary fibrosis in a subgroup, with inexorable progression despite treatment...

BACKGROUND: Early recognition of patients with interstitial lung disease (ILD) who have an increased risk of developing acute exacerbation (AE) or preclinical AE may be clinically useful, since AE is associated with poor outcome and preventive measures would be of interest to ILD researchers. This study evaluated the relationship between elevated serum D-dimer level (≥0.4 mcg/mL) and subsequent AE or preclinical AE in patients with ILD. METHODS: This single-center, retrospective study was performed from October 2009 through September 2015 in patients with ILD who were ≥18 years old and had idiopathic pulmonary fibrosis, other idiopathic interstitial pneumonias, chronic hypersensitivity pneumonitis, ILD related to collagen tissue disease, or combined pulmonary fibrosis/emphysema...

Hypersensitivity pneumonitis (HP) is an immune-mediated interstitial lung disease caused by recurrent exposure to one or more offending inducers in genetically susceptible individuals. It mimics other acute and chronic pulmonary diseases and is often misdiagnosed as idiopathic pulmonary fibrosis (IPF) or another idiopathic interstitial pneumonia if the history of exposure to the inducer is not elicited. We propose a new classification of HP based not only on clinical data but also radiologic and histopathologic findings which might have potential to serve as predictors of disease behaviour and therefore guide management...

PURPOSE: Several studies have reported that an acute exacerbation (AE) of idiopathic interstitial pneumonia (IIP) can occur after lung resection in patients with non-small cell lung cancer (NSCLC); however, the perioperative management strategy is controversial. METHODS: The data of lung cancer patients at Nagasaki University Hospital from June 1994 to October 2013 were retrospectively reviewed. RESULTS: Among all 1701 NSCLC patients who underwent lung resection, 59 (3...

PURPOSE: To compare computer-aided diagnostic results with histological findings obtained by surgical biopsy and evaluate whether subpleural lesion volumes can aid identification of idiopathic pulmonary fibrosis (IPF). MATERIALS AND METHODS: We retrospectively analyzed computed tomography (CT) images of 79 patients (43 with fibrosing nonspecific interstitial pneumonia (fNSIP) and 36 with IPF) using the Gaussian Histogram Normalized Correlation (GHNC) system. We determined the H-pattern based on honeycomb and/or fibrosis with traction bronchiectasis on CT, and measured the H-pattern volume ratio at the biopsy sites and in the subpleural area...

Lung ailments in rheumatic diseases present unique challenges for diagnosis and management and are a source of significant morbidity and mortality for patients. Unlike the idiopathic interstitial pneumonias, patients with rheumatic diseases experience lung disease in the context of a systemic disease that may make it more difficult to recognize and that may present greater risks with treatment. Despite recent advances in our awareness of these diseases, there is still a significant lack of understanding of natural history to elucidate which patients will have disease that is progressive and thus warrants treatment...

CONTEXT: - Chronic hypersensitivity pneumonitis (CHP) has emerged from obscurity during the past 15 years and is now recognized as a very common form of fibrosing interstitial pneumonia but one that is frequently misdiagnosed both clinically and on surgical lung biopsy as usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF) or fibrotic nonspecific interstitial pneumonia. OBJECTIVE: - To review the pathologic features of CHP. DATA SOURCES: - Clinical, pathology, and radiology literature were used...

INTRODUCTION: The current understanding of associations between lung disease and military deployment to Southwest Asia, including Iraq and Afghanistan, is both controversial and limited. We sought to clarify the relation between military deployment and biopsy-proven lung disease. METHODS: Retrospective data were analyzed for military personnel with non-neoplastic lung biopsies evaluated at the Armed Forces Institute of Pathology or Joint Pathology Center (January 2005 to December 2012)...

Cigarette smoking is the most frequently encountered risk factor for chronic obstructive pulmonary disease and lung cancer. The latest American Thoracic Society÷European Respiratory Society classification of idiopathic interstitial pneumonia includes two entities related to smoking habits: respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia. The new approach to diagnosis is to combine pathological pattern with clinical and radiological data. Lung biopsy is no longer considered the "gold standard" for diagnosis, but as a part of the diagnosis, which shall be set only after the pulmonologist, radiologist and pathologist reviewed all clinical, imaging and pathological aspects...

BACKGROUND AND OBJECTIVE: Lobar and temporal histological variability in chronic bird-related hypersensitivity pneumonitis (BRHP) has not been clearly elucidated. This study was designed to evaluate the spatio-temporal histopathological variability in chronic BRHP. METHODS: Fifty-two patients with chronic BRHP who underwent a surgical lung biopsy (SLB) between 1992 and 2008 were evaluated. The histopathological characteristics of the lung biopsy specimens were classified by the 2002 American Thoracic Society/European Respiratory Society (ATS/ERS) consensus classification of idiopathic interstitial pneumonias (IIPs)...

BACKGROUND AND OBJECTIVE: Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) (AE-IPF) is a poor prognostic disorder. AE is also reported to occur in other idiopathic interstitial pneumonias (IIPs). There are limited data available regarding the effectiveness of treatment for AE-IIPs. The objective of this study was to clarify the prognostic impact of the initial dose of prednisolone (PSL) for treating AE-IIPs. METHODS: Eighty-five patients with AE-IIPs, diagnosed according to the criteria of the Japanese Respiratory Society, were enrolled in this study (IPF/non-IPF: 63/22 patients) from 2004 to 2013...

INTRODUCTION: Both genetic and environmental factors are implicated in the pathogenesis of interstitial lung disease (ILD). Single-nucleotide polymorphisms (SNPs) in FOXP3 genes were implicated in the causation of some autoimmune diseases; however, association of these genes and ILD has not been reported. OBJECTIVES: To investigate whether FOXP3 polymorphisms are associated with ILD in a representative Chinese population. METHODS: One hundred and fifty-seven ILD patients and 170 healthy controls were recruited; SNPs were genotyped by the Sequenom MassARRAY platform and SHEsis was used to estimate the haplotype frequencies of SNPs...
