Abstract:
A middle-aged woman presented with symptoms suggestive of allergic asthma but with markedly elevated peripheral eosinophilia. She did not respond to inhaled corticosteroids, thereby prompting further investigations. Chest radiograph was normal. CT of the chest revealed bi-apical ground glass opacities. Bronchoalveolar lavage revealed predominantly eosinophilic yield. Autoimmune screen was negative. Bone marrow biopsy showed a normocellular marrow with increased eosinophils. A diagnosis of chronic eosinophilic pneumonia (CEP) was made after exclusion of other causes of eosinophilia. Treatment of her CEP with systemic corticosteroids (prednisolone 0.5 mg/kg/day) resulted in dramatic improvement in symptoms and peripheral eosinophilia.

Asthma: Pathogenesis and Management
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.
Asthma-II: Pathophysiology and Classification
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:
