PURPOSE: To quantify lesions in the subpleural lung region (SubPL) on computed tomography (CT) images and to evaluate whether they are useful for detecting interstitial lung disease (ILD). MATERIALS AND METHODS: The subjects were 40 patients with idiopathic pulmonary fibrosis (IPF) diagnosed by multidisciplinary methods and 35 age-matched patients without ILDs. The lungs and SubPL were extracted from CT images using a Gaussian histogram normalized correlation system and evaluated for the mean CT attenuation value (CTmean) and the percentage of high attenuation area (%HAA), exceeding -700 Hounsfield units...

BACKGROUND: Interstitial lung disease (ILD) is a disease with high mortality worldwide. Unfortunately, its prognosis is still very poor. Therefore, developing the target molecular is very important for ILD diagnosis and treatment. Caveolin-1 (Cav-1) can regulate the formation of fibrosis by linking to the signaling pathway of transforming growth factor-β1 (TGF-β1), which is generally considered to be the most effective approach to solve the problem of ILD. METHODS: The rat model of ILD was induced by disposable transtracheal injection of bleomycin hydrochloride...

BACKGROUND AND OBJECTIVE: Interstitial lung disease (ILD) is a common pulmonary manifestation of systemic sclerosis (SSc). It is unknown whether radiographic fibrosis score predicts mortality in SSc-associated ILD (SSc-ILD). We retrospectively analysed patients with SSc-ILD to evaluate whether radiographic fibrosis score was a useful predictor of mortality. METHODS: We identified SSc-ILD patients evaluated at Kurashiki Central Hospital (Japan) from 2006 to 2016, and radiographic fibrosis scores based on the extent of reticulation and honeycombing on high-resolution computed tomography (HRCT) scanning were calculated by manually tracing around each fibrotic area...

Objective In 2011, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification categorized chronic obstructive pulmonary disease (COPD) patients into 4 groups. A report demonstrated that the mortality in Group B was higher than that in Group C. Ischemic heart disease and cancer were suggested to be the cause. The aim of the present study was to test the hypothesis that interstitial lung abnormalities (ILAs) are more prevalent in Group B than Group C and that they may be responsible for the higher mortality in Group B...

Interstitial lung disease (ILD) is a major pulmonary manifestation of connective tissue disease (CTD), leading to significant morbidity and mortality. Chest high-resolution computed tomography (HRCT) is presently considered the diagnostic gold standard for pulmonary fibrosis diagnosis and quantification in the clinical arena. However, not negligible doses of ionizing radiation limit the use of HRCT, especially for serial follow-up in younger female patients. In the past decade, lung ultrasound (LUS) has been proposed to assess ILD by detecting and quantifying sonographic B-lines...

REVIEW
David N O'Dwyer, Bethany B Moore
Periostin is a protein that plays a key role in development and repair within the biological matrix of the lung. As a matricellular protein that does not contribute to extracellular matrix structure, periostin interacts with other extracellular matrix proteins to regulate the composition of the matrix in the lung and other organs. In this review, we discuss the studies exploring the role of periostin to date in chronic respiratory diseases, namely asthma and idiopathic pulmonary fibrosis. Asthma is a major health problem globally affecting millions of people worldwide with significant associated morbidity and mortality...

Lung diseases are increasing in prevalence and overall burden worldwide. To stem the tide, more and more national and international guidelines are recommending the use of various diagnostic algorithms that are disease specific. There is growing consensus among the respiratory community that although patient histories and lung function testing are the minimum required for clinical examinations, these tests alone are not sufficient for disease characterization. Therefore, the use of computed tomography (CT) imaging is increasing used in clinical decision making for lung diseases...

BACKGROUND: MUC1 (MUC in human and Muc in animals) is a membrane-tethered mucin expressed on the apical surface of lung epithelial cells. However, in the lungs of patients with interstitial lung disease, MUC1 is aberrantly expressed in hyperplastic alveolar type II epithelial (ATII) cells and alveolar macrophages (AM), and elevated levels of extracellular MUC1 are found in bronchoalveolar lavage (BAL) fluid and the serum of these patients. While pro-fibrotic effects of extracellular MUC1 have recently been described in cultured fibroblasts, the contribution of MUC1 to the pathobiology of pulmonary fibrosis is unknown...

In common variable immunodeficiency, lung manifestations are related to different mechanisms: recurrent pneumonias due to encapsulated bacteria responsible for diffuse bronchiectasis, diffuse infiltrative pneumonia with various patterns, and lymphomas, mostly B cell extranodal non-Hodgkin type. The diagnosis relies on significant serum Ig deficiency and the exclusion of any primary or secondary cause. Histopathology may be needed. Immunoglobulin (IgG) replacement is crucial to prevent infections and bronchiectasis...

PURPOSE: Secondary spontaneous pneumothorax (SSP) is difficult to treat by itself and due to its association with serious underlying diseases. It has a high rate of recurrence and often requires extended hospitalization. Therefore, we evaluated the outcome and risk factors associated with recurrence and extended hospitalization. METHODS: We retrospectively examined 61 patients with SSP, and evaluated the patients' characteristics, underlying diseases, introduction of home oxygen therapy, Brinkman index, and X-ray imaging findings to determine the risk factors for recurrence and extended hospitalization...

AIM: Interstitial lung disease (ILD) in infants represents a rare and heterogenous group of disorders, distinct from those occurring in adults. In recent years a new entity within this category is being recognized, namely filamin A (FLNA) mutation related lung disease. Our aims are to describe the clinical and radiological course of patients with this disease entity to aid clinicians in the prognostic counseling and management of similar patients they may encounter. METHOD: A retrospective case note review was conducted of all patients treated at our institution (a specialist tertiary referral childrens' center) for genetically confirmed FLNA mutation related lung disease...

A 59-year-old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre-stenting...

BACKGROUND: Little is known about the epidemiology of interstitial lung disease (ILD) amongst Canada's Indigenous populations. Clinicians working in Eeyou Istchee (the Cree territory of the James Bay region of Québec, population 17, 956) suspected that ILD was more common in this area. We sought to identify all prevalent and incident cases of ILD in Eeyou Istchee between 2006 and 2013, to describe characteristics of affected patients, distribution of subtypes, and estimate disease incidence...

BACKGROUND: Late-onset noninfectious pulmonary complications (LONIPCs), which occur more than 3 months after allogeneic hematopoietic stem cell transplantation (HSCT), are major causes of morbidity and mortality after transplantation. Among LONIPCs, we occasionally treat patients with late-onset severe restrictive lung defect after HSCT; however, its clinical features have not been fully elucidated. METHODS: A retrospective chart review of a single center on cases of late-onset severe restrictive lung defect after HSCT was performed...
