Extrinsic allergic alveolitis [PDF]

Respirology, 2006
Abstract: Extrinsic allergic alveolitis (also known as hypersensitivity pneumonitis) is caused by repeated inhalation of mainly organic antigens by sensitized subjects. This induces a hypersensitivity response in the distal bronchioles and alveoli and subjects may present clinically with a variety of symptoms.

NEW SCHEMES IN THE TREATMENT OF EXTRINSIC ALLERGIC ALVEOLITIS

Медицинский совет, 2013
Extrinsic allergic alveolitis (EAA) also known as hypersensitivity pneumonitis is an inflammatory process in the lungs resulting from sensitization caused by repeated exposure to organic dust or low molecular weight agents.

Concomitant diagnosis of hypersensitivity pneumonitis and localized epithelioid mesothelioma: a rare case report [PDF]

Einstein (São Paulo)
Hypersensitivity pneumonitis is an inflammatory lung disease caused by antigen inhalation after sensitization. Here, we report a rare case of the simultaneous diagnosis of hypersensitivity pneumonitis and epithelioid mesothelioma, a subtype of malignant ...

Quantitative assessment of specific serum IgGs may verify source of environmental exposure in extrinsic allergic alveolitis (EAA)

Cogent Medicine, 2021
:  Assessment of humoral response to inhalation antigens is currently the most frequently used method to confirm exposure. It may be useful in extrinsic allergic alveolitis (EAA) patients, especially in cases that are unaware of the source of exposure ...

Alveolite alérgica extrínseca com expressão imunológica atípica Extrinsic allergic alveolitis with an atypical immune expression

Revista Portuguesa de Pneumologia, 2009
A alveolite alérgica extrínseca e a sarcoidose são ambas doenças granulomatosas pulmonares que se caracterizam pela presença de granulomas não necrotizantes. Ambas apresentam alterações típicas no lavado broncoalveolar, com relações CD4/CD8 opostas.

Allogeneic Hematopoietic Stem Cell Transplantation Despite Severe Fusarium solani Infection in a Lung Transplanted Patient—A Case Report [PDF]

Microorganisms
Solid-organ transplant patients require prolonged immunosuppression, increasing their risk of hematologic disorders. For these conditions, allogeneic hematopoietic stem cell transplantation (HSCT) is a potential treatment, but it carries significant risk

Protein kinase D1 in myeloid lineage cells contributes to the accumulation of CXCR3+CCR6+ nonconventional Th1 cells in the lungs and potentiates hypersensitivity pneumonitis caused by S. rectivirgula [PDF]

Frontiers in Immunology
IntroductionHypersensitivity pneumonitis (HP) is an extrinsic allergic alveolitis characterized by inflammation of the interstitium, bronchioles, and alveoli of the lung that leads to granuloma formation.

BN 52021 (a platelet activating factor-receptor antagonist) decreases alveolar macrophage-mediated lung injury in experimental extrinsic allergic alveolitis

Mediators of Inflammation, 1998
Several lines of research indirectly suggest that platelet activating factor (PAF) may intervene in the pathogenesis of extrinsic allergic alveolitis (EAA).

Using Multiple Diagnostic Methods for Occupational Asthma Assessment. [PDF]

Clin Respir J
PC20 variability demonstrated higher diagnostic accuracy than PEFR monitoring in occupational asthma (OA), with a sensitivity of 90% and specificity of 92%. PEFR alone resulted in a 22.2% misclassification rate. Incorporating PC20 variability into diagnostic evaluation may reduce misdiagnosis and improve clinical outcomes in high‐exposure settings ...

Severe Occupational Hypersensitivity Pneumonitis: A Case Series of Four Patients Requiring Lung Transplantation. [PDF]

Am J Ind Med
ABSTRACT Hypersensitivity pneumonitis (HP) is an immune‐mediated interstitial lung disease triggered by repeated inhalation of organic or chemical antigens. Occupational exposures account for approximately 19% of all cases. Early diagnosis, identification of the responsible antigen(s), and immediate avoidance of exposure are crucial to prevent ...
