Expert Review of Clinical Immunology
|February 4, 2014
Summary
Preventing allergies early in life is challenging. Allergy immunotherapy during pregnancy may modulate the immune system, potentially influencing offspring
Area of Science:
- Immunology
- Allergy Research
- Preventive Medicine
Background:
- Primary prevention of allergies remains a significant clinical challenge.
- Current strategies lack unequivocal supporting data.
- Early-life immune modulation, potentially in utero, is crucial for successful allergy prevention.
Discussion:
- Early exposure to environmental factors like bacteria and farm animals suggests immune regulation via fetal exposure.
- Clinical applications, such as probiotics, have yielded limited success.
- Allergy immunotherapy (AIT) offers a potential clinical method for immune modulation.
Key Insights:
- Administering AIT to atopic pregnant women may induce favorable immune modulation.
- Maternal immune changes during pregnancy could influence the atopic status of offspring.
- This approach aligns with the need for early-life intervention in allergy prevention.
Outlook:
- Further research is needed to validate AIT during pregnancy as a primary allergy prevention strategy.
- Investigating the precise mechanisms of maternal-fetal immune transfer is essential.
- Exploring preconception AIT could offer an extended window for immune programming.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
2.4K
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...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

01:30Allergic Reactions: Anaphylaxis
280
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

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...
