Eosinophilic esophagitis (EoE) is a T-helper 2 inflammatory disease triggered by allergens, often co-occurring with other allergic conditions. New insights have led to the first pharmacological treatments for this chronic esophageal condition.
Area of Science:
- Immunology
- Genetics
- Gastroenterology
Background:
- Eosinophilic esophagitis (EoE) is a chronic esophageal inflammatory disease.
- It presents as dysphagia in adults and refractory reflux in children.
Purpose of the Study:
- To elucidate the pathophysiology of eosinophilic esophagitis.
- To identify triggers and contributing factors in EoE development.
Main Methods:
- Utilized immunological approaches.
- Employed genetic analyses to understand inflammation.
Main Results:
- EoE is characterized as a T-helper (Th) 2-type inflammatory disease.
- Allergens are implicated as key triggers for EoE.
- Patients frequently have concurrent allergic rhinitis, asthma, eczema, and a history of atopy.
Conclusions:
- Chronic inflammation in EoE leads to esophageal tissue damage, remodeling, dysfunction, and bolus impaction.
- Advances in understanding EoE pathophysiology have enabled the development of novel pharmacological therapies.

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.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
