[Research advances on polyunsaturated fatty acids in pediatric asthma]
Summary
Polyunsaturated fatty acids (PUFAs) like omega-3 and omega-6 can help manage pediatric asthma by regulating immune responses. This review explores their role in preventing and treating childhood asthma through nutrition.
Area of Science:
- Immunology
- Nutrition Science
- Pediatric Medicine
Background:
- Pediatric asthma is a chronic inflammatory airway disease often linked to immune dysregulation.
- A common Type 2 (T2) inflammatory phenotype involves eosinophils, mast cells, and basophils, driven by T-helper 2 (Th2) cells and group 2 innate lymphoid cells (ILC2s).
- Severe asthma cases risk irreversible airflow limitation.
Purpose of the Study:
- To systematically review the biological properties of omega-3 and omega-6 polyunsaturated fatty acids (PUFAs).
- To emphasize the functional roles and molecular mechanisms of PUFAs in pediatric asthma.
- To provide evidence-based strategies for early prevention and precision nutritional intervention in childhood asthma.
Main Methods:
- Systematic literature review.
- Analysis of biological properties and molecular mechanisms of PUFAs.
- Focus on immune-inflammatory responses and gut microbial homeostasis.
Main Results:
- PUFAs exert significant regulatory effects on immune-inflammatory pathways relevant to asthma.
- Specific PUFAs modulate T2 inflammation and associated cellular infiltration.
- Evidence suggests PUFAs can support gut microbial balance, influencing asthma pathogenesis.
Conclusions:
- Omega-3 and omega-6 PUFAs hold therapeutic potential in pediatric asthma management.
- Understanding PUFA mechanisms can inform targeted nutritional strategies for prevention and treatment.
- Precision nutrition interventions focusing on PUFAs may improve outcomes for children with asthma.

1.7K
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.

2.3K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

4.9K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
2.3K
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...

3.7K
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...
