Endometriosis and anxiety significantly increase the likelihood of asthma and allergic rhinoconjunctivitis in women. The combination of both conditions showed the strongest association, particularly in younger women, suggesting shared inflammatory pathways.
Area of Science:
- Reproductive Health
- Immunology
- Pulmonology
- Psychiatry
Background:
- Endometriosis is a chronic inflammatory condition affecting women of reproductive age.
- Anxiety disorders are prevalent and can significantly impact quality of life.
- Asthma and allergic rhinoconjunctivitis are common inflammatory conditions with known links to immune system dysregulation.
Purpose of the Study:
- To investigate the associations between endometriosis, anxiety, allergic rhinoconjunctivitis, and asthma in hospitalized women.
- To determine if age influences these associations.
Main Methods:
- A cross-sectional study utilizing a large dataset of 12,814,970 hospitalized women aged 18-49 from the U.S. Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) between 2007 and 2014.
- Diagnoses were identified using ICD-9 codes.
- Multivariable logistic regression models were employed to calculate adjusted odds ratios (ORs), controlling for various demographic and clinical factors. Analyses were stratified by age groups (18-34 and 18-49 years).
Main Results:
- The coexistence of anxiety and endometriosis was linked to the highest odds of asthma (ORs ranging from 2.07 to 2.57) and allergic rhinoconjunctivitis (ORs ranging from 2.78 to 3.45) among hospitalized women.
- These associations were stronger in younger women (aged 18-34 years).
- Anxiety or endometriosis as isolated conditions also showed significant associations with both asthma and allergic rhinoconjunctivitis.
Conclusions:
- Endometriosis and anxiety are independently associated with increased odds of asthma and allergic rhinoconjunctivitis.
- The combined presence of endometriosis and anxiety demonstrates a potentially synergistic effect, leading to the highest likelihood of these respiratory and allergic conditions.
- These findings underscore the importance of considering psychological and inflammatory comorbidities in the clinical management of women with endometriosis, anxiety, asthma, or allergic rhinoconjunctivitis, and suggest further research into shared inflammatory mechanisms.

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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
