Summary
Longer sublingual immunotherapy (SLIT) in children with asthma improves outcomes. Increased parental education was linked to longer SLIT duration, which in turn reduced uncontrolled asthma symptoms.
Area of Science:
- Pediatric Allergy and Immunology
- Respiratory Medicine
- Real-world Evidence Studies
Background:
- Sublingual immunotherapy (SLIT) administered daily for three years is known to reduce allergic disease symptoms and induce tolerance.
- Real-world data on children with asthma undergoing SLIT is limited.
Purpose of the Study:
- To describe the characteristics of children with asthma prescribed SLIT.
- To analyze SLIT duration and its impact on asthma morbidity in a real-world setting.
Main Methods:
- Population-based study utilizing the Swedish National Airway Register (SNAR) and other national registers.
- Included 1,514 children (5-17 years) with asthma prescribed SLIT, with 782 having post-SLIT data.
- Data extracted included age, sex, Asthma Control Test scores, spirometry, SLIT dispensing records, and socioeconomic background.
Main Results:
- SLIT was more prevalent in boys (69%) and adolescents (71%).
- Higher parental education was associated with longer SLIT duration (≥4 months).
- SLIT duration exceeding 12 months correlated with a reduced risk of uncontrolled asthma (aOR=0.49).
Conclusions:
- Extended duration of SLIT in children with asthma is associated with parental higher education.
- Longer SLIT treatment is linked to a decreased likelihood of uncontrolled asthma.
- Strategies to enhance SLIT adherence in pediatric asthma patients could yield significant clinical benefits.

1.7K
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:

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
1.7K
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...

01:20Asthma: Pathogenesis and Management
1.2K
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.

3.3K
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...

1.5K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
