Introduction:
Case reports describe individuals with achalasia features subsequently diagnosed with eosinophilic esophagitis (an atopic disorder). We have examined associations between achalasia and atopic and autoimmune conditions.
Methods:
This is a UK cohort study of 2,593 subjects with achalasia matched to 10,402 controls.
Results:
At diagnosis, achalasia was associated with autoimmune conditions (odds ratio 1.39; 95% confidence interval 1.02-1.90) and atopic conditions (1.40; 1.00-1.95) in those aged younger than 40 years.
Disscussion:
Our findings support an autoimmune etiology in achalasia but also suggest a possible atopic etiology in younger subjects.

Asthma-I: Introduction
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.
