Idiopathic interstitial pneumonias

Idiopathic interstitial pneumonia (IIP), or noninfectious pneumonia are a class of diffuse lung diseases. These diseases typically affect the pulmonary interstitium, although some also have a component affecting the airways (for instance, cryptogenic organizing pneumonitis). There are seven recognized distinct subtypes of IIP Unclassifiable idiopathic interstitial pneumonias* *Causes of unclassifiable idiopathic interstitial pneumonia include (1) inade-quate clinical, radiologic, or pathologic data and (2) major discordance between clinical, radiologic, and pathologic findings that may occur in the following situa Disorders without a known cause are grouped together under the label of idiopathic interstitial pneumonias, the most common and deadly of which is idiopathic pulmonary fibrosis

[Idiopathic interstitial pneumonias]

Idiopathic interstitial pneumonias are interstitial lung diseases that have no known cause that have some similarities in symptoms and how they affect the lungs. Some types of these diseases are much more serious than others. Diagnosis requires chest x-rays, computed tomography, and usually analysis of a sample of lung tissue (biopsy) Nonspecific interstitial pneumonia (NSIP) is a rare disorder that affects the tissue that surrounds and separates the tiny air sacs of the lungs. These air sacs, called the alveoli, are where the exchange of oxygen and carbon dioxide takes place between the lungs and the bloodstream

Idiopathic Interstitial Pneumonia - an overview

  1. Idiopathic interstitial pneumonias comprise usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis-associated interstitial lung disease (RB-ILD), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), and lymphoid interstitial pneumonia (LIP)
  2. IDIOPATHIC INTERSTITIAL PNEUMONIAS. The term idiopathic interstitial pneumonia (IIP) is applied to a group of inflammatory and fibrotic lung diseases with distinct histologic and imaging appearances, and without a known cause. The concept of interstitial pneumonia originated with Liebow and Carrington, and the first comprehensive and critical.
  3. The most important distinction among the IIPs is that between idiopathic pulmonary fibrosis (IPF) and the other interstitial pneumonias, which include nonspecific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis-associated interstitial lung disease (RBILD), acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP), and lymphocytic interstitial pneumonia (LIP)

The idiopathic interstitial pneumonias (IIPs) are a heterogeneous group of conditions that can be characterized by specific radiographic and histologic features. Radiographically, they are described as diffuse parenchymal lung diseases (DPLDs) with distinct patterns of injury. The prognoses for different types of IIPs range from very poor (AIP. Idiopathic Pulmonary Fibrosis IPF is defined as a specific form of chronic progressive fibrosing interstitial pneumonia of unknown cause that occurs primarily in older adults and is associated with the histopathologic or radiologic pattern of UIP. Prognosis is poor, with a median survival of less than 5 years (29) Idiopathic Interstitial Pneumonias Overview - Insights in ILD. IIPs are a class of ILDs of unknown etiology characterized by varying degrees of inflammation and fibrosis 1; Clinical history, HRCT findings, and pathology results should be taken into consideration when diagnosing patients with IIPs 2; HRCT, high-resolution computed tomography

Introduction. The 2013 updated classification of the idiopathic interstitial pneumonias (IIPs) includes two very uncommon entities sub-classified as 'rare IIPs' (LIP (lymphoid interstitial pneumonia) and IPPFE (idiopathic pleuroparenchymal fibroelastosis), recently recognized as a distinct entity) Paclitaxel for relapsed small-cell lung cancer patients with idiopathic interstitial pneumonias Mol Clin Oncol. 2019 May;10(5):541-546. doi: 10.3892/mco.2019.1828.

The idiopathic interstitial pneumonias (IIPs) comprise a group of diffuse lung diseases of unknown aetiology that primarily involve the pulmonary interstitium—the area between the alveolar epithelium and capillary endothelium, as well as the septal and bronchovascular tissues that make up the fibrous framework of the lung Idiopathic interstitial pneumonias (IIPs) are a group of diffuse parenchymal lung diseases of unknown etiology with varying degrees of inflammation and fibrosis. 1 Several classifications for IIPs have been proposed. The most widely accepted scheme is the 2002 American Thoracic Society/European Respiratory Society (ATS/ERS) consensus classification. 1 This classification divides the IIPs into. In the American Thoracic Society/European Respiratory Society international multidisciplinary consensus classification of the idiopathic interstitial pneumonias published in 2002, it is stated that Idiopathic indicates unknown cause and interstitial pneumonia refers to involvement of the lung parenchyma by varying combinations of fibrosis. The idiopathic interstitial pneumonias are a subset of diffuse interstitial lung diseases of unknown etiology characterized by expansion of the interstitial compartment (ie, that portion of the lung parenchyma sandwiched between the epithelial and endothelial basement membranes) with an infiltrate of inflammatory cells

Idiopathic pulmonary fibrosis is the clinical term for usual interstitial pneumonia. The radiologic pattern includes basal and subpleural ground glass and reticular opacities and honeycomb lung. Nonspecific interstitial pneumonia is characterized with a radiologic pattern of subpleural and basal ground glass and reticular opacities The idiopathic interstitial pneumonias (IIP) refer to a group of distinct clinicopathologic entities without known causes [ 1 ]. Classification of IIP has undergone several iterations as understanding of these entities evolves [ 2, 3, 4 ]. The most common IIP is idiopathic pulmonary fibrosis (IPF), which accounts for approximately 40% of all. Idiopathic pulmonary fibrosis is the most predominant idiopathic interstitial pneumonias and its diagnosis needs to omit all other well-known causes of interstitial lung diseases. According to the 2011 evidence-based guidelines, usual interstitial pneumonia can be diagnosed by HRCT when all criteria are fulfilled. Non-specific interstitial. Rare Idiopathic Interstitial Pneumonias Allen P. Burke, M.D. Marie-Christine Aubry, M.D. Seth Kligerman, M.D. Idiopathic Pleuroparenchymal Fibroelastosis Background Idiopathic pleuroparenchymal fibroelastosis (PPFE) was initially described in 2004 as a form of idiopathic interstitial pneumonia characterized by predominantly upper lobe subpleural scarring with elastosis.1 Recently, it was.

Idiopathic interstitial pneumonias (IIPs) are progressive fibrotic diseases of the lungs with unknown etiology 1.Although their precise prevalence is unclear, IIPs are not uncommon and idiopathic. Acute exacerbation of chronic fibrosing idiopathic interstitial pneumonias (AE-IIPs) is associated with a high mortality rate. In 2016, an international working group proposed a revised diagnostic criteria for AE-IIPs, suggesting that it be classified as idiopathic or triggered. Many factors are known to trigger AE-IIPs, including surgery, infection, and drugs Idiopathic pulmonary fibrosis (IPF), the most common and lethal of the idiopathic interstitial pneumonias, is defined by a radiological and/or pathological pattern of usual interstitial pneumonia (UIP). However, UIP is not synonymous with IPF as other clinical conditions may be associated with UIP, including chronic hypersensitivity pneumonitis, collagen vascular disease, drug toxicity. The interstitial pneumonias (IPs) are a heterogeneous group of diffuse parenchymal lung diseases characterized by specific clinical, radiologic and pathologic features. While pathologically defined, significant overlap in terms of presentation as well as association with secondary diseases is known and may confound initial work-up and diagnosis

Types of idiopathic interstitial pneumonias. There are several Interstitial Pneumonias. In the 1960's, Professor Liebow used the term usual interstitial pneumonia (UIP) for the most common form. He described Desquamative Interstitial Pneumonia (DIP), Lymphocytic Interstitial Pneumonia (LIP), and Giant Cell Interstitial Pneumonia (GIP)

Idiopathic interstitial pneumonias (IIPs) may have an acute or subacute presentation, or acute exacerbation may occur in a previously subclinical or unrecognized chronic IIP. Acute or subacute IIPs include acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP), nonspecific interstitial pneumonia (NSIP), acute exacerbation of.

Abstract. In the past decade, concepts in classification, pathogenesis, and histopathology of the idiopathic interstitial pneumonias have undergone considerable change. This evolution has had a substantial impact on the approach to the diagnosis and clinical management of these patients. Some of the changes have led to considerable confusion. Idiopathic interstitial pneumonia with autoimmune features (IPAF) is an overlap between idiopathic interstitial pneumonia and connective tissue disease-associated ILD, so the following conditions must be ruled out while making a diagnosis of IPAF. Idiopathic pulmonary fibrosis (IPF) Connective tissue disease-associated ILD (CTD-ILD

Some patients with autoimmune characteristics and idiopathic interstitial pneumonia, particularly usual interstitial pneumonia (UIP), do not fit neatly into the category of connective tissue disease-associated interstitial lung disease (CTD-ILD), idiopathic pulmonary fibrosis (IPF), or recently proposed yet to be validated criteria for interstitial pneumonia with autoimmune features (IPAF) 2. • Idiopathic interstitial pneumonias (IIPs) encompass a sub-category of interstitial lung diseases (ILDs) that pose significant diagnostic and management challenges. 3.
