Humoral and cellular immunity in asthma
The Journal of Allergy and Clinical Immunology
|March 1, 1975
Summary
Asthma may be linked to immune system deficiencies. This study found altered immunoglobulin levels and impaired immune responses in asthmatic patients, suggesting a connection to immunodeficiency states.
Area of Science:
- Immunology
- Allergy Research
Background:
- Asthma is a complex respiratory condition with potential links to immune system dysfunction.
- Understanding immune parameters in asthma is crucial for identifying underlying mechanisms.
Purpose of the Study:
- To investigate humoral and cellular immunity in asthmatic patients.
- To explore potential associations between immune system parameters and asthma phenotypes.
Main Methods:
- Measured serum immunoglobulin (IgG, IgE, IgA) levels in 91 asthmatic patients.
- Assessed immune responses through tetanus and Salmonella typhi H antigen immunization.
- Evaluated cellular immunity via delayed hypersensitivity reactions and lymphocyte proliferation assays (tritiated thymidine uptake).
Main Results:
- Elevated mean serum IgG and IgE levels were observed.
- Higher IgG levels correlated with a family history of asthma; higher IgE with atopic eczema history.
- Impaired responses to tetanus immunization and delayed hypersensitivity were noted in some patients, associated with altered lymphocyte function and elevated IgA.
Conclusions:
- Asthma may be associated with specific immunodeficiency states.
- Findings suggest a potential role for immune dysregulation in asthma pathogenesis.
- Further research is warranted to elucidate the relationship between asthma and immunodeficiency.

1.5K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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 is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
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...

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

01:28Asthma I: Introduction
112
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
