Summary
Eosinophilic bronchitis causes chronic coughs and responds to corticosteroids. This condition, distinct from asthma, involves superficial airway eosinophils but not smooth muscle infiltration, suggesting different disease mechanisms.
Area of Science:
- Respiratory Medicine
- Immunology
- Pathophysiology
Background:
- Eosinophilic bronchitis is a condition characterized by chronic coughs.
- It presents without the typical physiological features of asthma.
Purpose of the Study:
- To review the clinical features, pathogenesis, diagnosis, treatment, and prognosis of eosinophilic bronchitis.
- To differentiate eosinophilic bronchitis from asthma.
Main Methods:
- A literature review was conducted using PubMed.
- The search term "eosinophilic bronchitis" was used for English-language studies.
Main Results:
- Eosinophilic bronchitis shows normal spirometry and airway responsiveness.
- Superficial airway mast cell recruitment and activation are observed, unlike asthma's smooth muscle infiltration.
- Cough typically responds to inhaled corticosteroids, though optimal dosage and duration are unclear.
Conclusions:
- Eosinophilic bronchitis is a significant cause of chronic coughs responsive to corticosteroid therapy.
- The findings suggest eosinophil-dependent mechanisms are not central to asthma pathogenesis.

01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
