Interstitial lung disease (ILD) is an umbrella term for a broad spectrum of conditions affecting the lung interstitium, which is the space between an alveolus and its surrounding capillaries. 1 In the UK, the prevalence of ILD is 50 per 100,000. Since the initial classification of adult interstitial lung disease by Liebow and Carrington in 1969, there have been a number of proposals and revisions to this classification, culminating most recently in a revised American Thoracic Society/European Respiratory Society classification of idiopathic interstitial pneumonias in 2002 (). It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. Interstitial lung disease is a general category that includes many different lung conditions. Interstitial lung diseases are a group of diffuse parenchymal lung disorders associated with substantial morbidity and mortality. Some of the types of interstitial lung disease include: Interstitial pneumonia: Bacteria, viruses, or fungi may infect the interstitium of the lung. Historically, terminology and classification of interstitial lung disease (ILD) in children have mirrored those of adult disease, but this is generally not helpful. The pathology is often inflammatory and always requires clinical and radiological context for a relevant and clinically useful histopathological diagnosis. eCollection 2018. This paper presents an improved DenseNet called small kernel DenseNet (SK-DenseNet) to improve ILD classification performance.

SECTION 11 Immunologic and Interstitial Diseases CHAPTER 54 Interstitial Lung Disease: A Clinical Overview and General Approach Danielle Antin-Ozerkis INTRODUCTION Commonly, interstitial lung disease (ILD) presents with dyspnea on exertion, diffuse bilateral infiltrates on chest imaging, and restriction with diffusion impairment on physiologic testing. 1.3 Terminology of interstitial lung disease The term ‘‘interstitial lung disease’’ is synonymous with ‘‘diffuse parenchymal lung disease’’ and, while the latter was used in the 1999 BTS guideline, a decision was made to adopt interstitial lung disease in the current document, consistent with … Bjoraker JA, et al. The contributions of the European Respiratory Society Task Force on Interstitial Lung Disease in Children and the North American Children's Interstitial Lung Disease Group are reviewed, and a clinicopathologic classification of paediatric diffuse lung disease is summarized. Patients are often hypoxemic, and pulmonary function tests typically demonstrate a restrictive pattern, with reduced diffusing capacity. The correct diagnosis of ILD is beneficial to improve the effect of treatment for patients. Van Hoeyweghen RJ et al. Adult Still's disease and respiratory failure in a 74 year old woman. Background: There is growing recognition and understanding of the entities that cause interstitial lung disease (ILD) in infants.These entities are distinct from those that cause ILD in older children and adults. • ILD is not one disease but several diseases that do not necessarily share a common histopathological or pathophysiological basis According to the characteristics of HRCT features of lung disease, the SK-DenseNet … Lung damage from ILDs is often irreversible and gets worse over time. Lung Pattern Classification for Interstitial Lung Diseases Using a Deep Convolutional Neural Network Abstract: Automated tissue characterization is one of the most crucial components of a computer aided diagnosis (CAD) system for interstitial lung diseases (ILDs). 2002;78(916):97-8.

Knowledge achieved in recent years has resulted in the publication of the new classification of idiopathic interstitial pneumonias, according to which there are three groups: major, rare and unclassified. A case of adult-onset Still's disease complicated with diffuse alveolar hemorrhage. 2Pulmonary Unit, GB Morgagni Hospital, Forlı`, Italy. 1. Categories and Types of Interstitial Lung Diseases. Despite a thorough multidisciplinary evaluation, up to 15% of ILD patients have unclassifiable ILD and cannot be given a specific diagnosis. • ILD is also termed diffuse parenchymal lung disease (DPLD). Stoica GS et al. Clin Rheumatol. 3Dept of Am J Respir Crit Care Med. 2018 May 22;9(11):2054-2060. doi: 10.7150/jca.24936. Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) of the lungs. Worsening hypoxia and respiratory failure may develop with disease progression. Diseases in this group show common characteristics clinically, radiologically, pathologically and functionally. All interstitial lung diseases affect the interstitium, a part of the lungs' anatomic structure. Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the alveoli (air sacs of the lungs). Clinical classification groups ILD by its causes to help differentiate exogenous or endogenous factors. INTRODUCTION • Interstitial Lung Disease refers to a broad range of conditions that have common clinical, physiological, and radiological features. The Lancet Respiratory Medicine , … Postgrad Med J. The scarring causes stiffness in the lungs which makes it difficult to breathe and get oxygen to the bloodstream. J Cancer. None of the pre-existing lung disease included previous ILD. 1993;12(3):418-21. Interstitial lung disease Katerina M. Antoniou 1, George A.

Classification of usual interstitial pneumonia in patients with interstitial lung disease: Assessment of a machine learning approach using high-dimensional transcriptional data. ILD early and accurate diagnosis is challenging due to heterogeneity of the disease. Interstitial Lung Disease (ILD) is one of the popular respiratory diseases. 4. Interstitial lung diseases are a group of diffuse parenchymal lung disorders associated with substantial morbidity and mortality. as “RA-lung,” “RA–fibrosing alveolitis,” “RA–diffuse parenchymal ILD,” and “RA-pulmonary fibrosis” or “connective tissue disease–associated ILD.” As a result, studies of ILD in patients with RA have been hampered by a lack of acknowledged terminology and validated classification criteria. Classification. Knowledge achieved in recent years has resulted in the publication of the new classification of idiopathic interstitial pneumonias, according to which there are three groups: major, rare and unclassified. Interstitial lung disease (ILD) is a heterogeneous group of disorders that are characterised by varying degrees of fibrosis and inflammation of lung parenchyma. Even with multidisciplinary team assessment, 15-25% of ILD patients remain unclassifiable. Three cases were diagnosed as IPF which is a progressive lung disease; two of these had ongoing respiratory symptoms and radiological changes, but for one no respiratory data exist. NSIP is an area of uncertainty that requires further defini-tion. Accurate classification of interstitial lung disease (ILD) requires a multidisciplinary approach that incorporates input from an experienced respirologist, chest radiologist and lung pathologist. Introduction Interstitial lung disease (ILD) refers to a broad category of diffuse parenchymal lung diseases characterized by inflammation and/or fibrosis of the lungs. Dr. Sally Suliman presents "Interstitial Lung Disease" by first introducing the classification of ILDs. In the January issue of the American Journal of Respiratory and Critical Care Medicine the “ATS/ERS international multidisciplinary consensus classification of idiopathic interstitial pneumonias” 1 was published, and this certainly deserves an editorial comment in the European Respiratory Journal (ERJ). Sari I et al. Patients invariably present with dyspnea of varying time course and severity. nonspecific interstitial pneumonia (NSIP), cryptogenic or-ganizing pneumonia (COP), acute interstitial pneumonia (AIP), respiratory bronchiololitis-associated interstitial lung disease (RB-ILD), desquamative interstitial pneumo-nia (DIP), and lymphoid interstitial pneumonia (LIP). Current Classification of interstitial lung diseases. 1999;160:899-905. Interstitial lung disease and adult-onset Still's disease. Objective: Interstitial lung diseases is the name given to the acute or chronic disease group that affects the lung parenchyma as diffuse, causing inflammation, fibrosis and structural disorders in the parenchyma. Interstitial Lung Disease Catherine Chen and Adrian Shifren GENERAL PRINCIPLES Definition • Interstitial lung disease (ILD) describes a heterogeneous group of over 200 diseases affecting the pulmonary interstitium with varying degrees of involvement of the pleural space, airways, and pulmonary vasculature. Interstitial Lung Disease: Includes a diverse group of respiratory conditions characterised by inflammation and fibrosis of the interstitium. Am J Respir Crit Care Med.1998;157:199-203. The classification system used to describe interstitial lung disease categorizes conditions based on clinical, histopathological or radiologic parameters. There are about five broad categories of Interstitial Lung Diseases: Exposure or occupational related (asbestosis, silicosis, hypersensitivity pneumonitis) Treatment related: chemotherapy, radiation therapy, some medications The complex world of interstitial lung disease presents nearly insurmountable challenges to the general surgical pathologist faced with a lung biopsy in this setting. INTRODUCTION "Diffuse interstitial lung disease" (ILD) is a generic term encompassing a broad range of largely unrelated conditions that share the propensity to cause breathlessness and/or cough associated with bilateral abnormal opacities of various types on conventional chest radiographs or high resolution computed tomographic (HRCT) scans (algorithm 1).
