Adult linear IgA bullous dermatosis with bronchial involvement
Abstract:
A 54-year-old man is described, suffering from adult linear IgA bullous dermatosis with involvement of the bronchial mucosa. The main respiratory symptoms were recurring haemoptysis, episodic narrowing of the airways and persistent non-specific bronchial hyperreactivity. On CT scan the trachea had a saber-sheath shape with tracheal ring calcification. Endoscopically the tracheo-bronchial mucosa was diffusely purpuric and hyperaemic and also showed pale elevated plaques, bullous lesions and ulceration. Histological examination of biopsies of skin and nasal and tracheo-bronchial mucosa showed subepithelial blister formation associated with an accumulation of polymorphonuclear cells at the epithelial-subepithelial junction, and linear IgA deposits on direct immunofluorescence.

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.
