The most common symptom of eosinophilic bronchitis is a chronic dry cough lasting more than 6–8 weeks. [3] Eosinophilic bronchitis is also defined by the increased number of eosinophils, a type of white blood cell, in the sputum compared to that of healthy people. [2]
Eosinophilic pneumonia is a disease in which an eosinophil, a type of white blood cell, accumulates in the lungs. These cells cause disruption of the normal air spaces ( alveoli ) where oxygen is extracted from the atmosphere .
Eosinophilic bronchitis is a chronic dry cough, defined by the presence of an increased number of a type of white blood cell known as eosinophils. It has a normal finding on X-ray and has no airflow limitation.
Atopic cough occurs in individuals with a family history of atopy (an allergic condition), abundant eosinophils in the sputum, but with normal airway function and responsiveness. Eosinophilic bronchitis is characterized by eosinophils in sputum and in bronchoalveolar lavage fluid without airway hyperresponsiveness or an atopic background. [11]
Charcot–Leyden crystals are composed of an eosinophilic lysophospholipase binding protein called Galectin-10. They vary in size and may be as large as 50 μm in length. [1] Charcot–Leyden crystals are slender and pointed at both ends, consisting of a pair of hexagonal pyramids joined at their bases. [1]
Acute bronchitis; Other names: Chest cold: Figure A shows the location of the lungs and bronchial tubes. Figure B is an enlarged view of a normal bronchial tube. Figure C is an enlarged view of a bronchial tube with bronchitis. Specialty: Pulmonology: Symptoms: Cough with sputum, wheezing, shortness of breath, fever, chest discomfort [1] [2 ...
Whitish gray sputum color against a white color background (such as a white sink surface) tends to indicate either a specimen from someone who is dehydrated, and/or from an older person, and/or a specimen with a mixed, modest number of eosinophils and maybe some acute inflammatory neutrophil cells (this last choice tends to suggest chronic ...
Acute eosinophilic pneumonia (AEP) is an uncommon, acute-onset form of eosinophilic lung disease which varies in severity. Though poorly understood, the pathogenesis of AEP likely varies depending on the underlying cause which may include smoking, inhalation exposure, medication, and infection. [ 1 ]
