Insights
Treating preschool wheeze effectively requires understanding distinct phenotypes. Current treatments offer limited benefits, and phenotype-specific therapies are hindered by diagnostic challenges.
Area of Science:
- Pediatric Pulmonology
- Clinical Trials Research
- Respiratory Medicine
Background:
- Childhood wheeze encompasses diverse underlying conditions, necessitating targeted therapies for improved outcomes.
- Differentiating preschool wheeze phenotypes is crucial for effective, individualized treatment strategies.
Purpose of the Study:
- To review clinical trial data on preschool wheeze treatments, focusing on population characteristics and phenotypes.
- To evaluate the efficacy of various therapeutic approaches for different preschool wheeze phenotypes.
Main Methods:
- Systematic review of clinical trials investigating treatments for preschool wheeze.
- Analysis of study populations' characteristics and identified wheeze phenotypes.
- Assessment of treatment outcomes, including symptom improvement and hospitalization rates.
Main Results:
- Systemic corticosteroids show no benefit for mild-to-moderate preschool wheeze exacerbations.
- High-dose intermittent inhaled corticosteroids are not recommended due to side effects.
- Regular inhaled corticosteroids and leukotriene antagonists provide modest benefits but do not reduce hospitalizations.
- Emerging evidence suggests potential phenotype-specific treatment effects.
Conclusions:
- Current evidence does not support routine systemic corticosteroid use for preschool wheeze.
- While some treatments offer modest benefits, none consistently reduce hospitalizations.
- Accurate differentiation of clinically relevant preschool wheeze phenotypes is essential for advancing phenotype-directed treatment.
- Further research is needed to refine phenotype identification and guide targeted therapies.
Abstract:
Wheeze in childhood may comprise different underlying diseases. Disease-specific treatment could potentially improve treatment efficacy. Various attempts have been made to differentiate between pre-school wheeze phenotypes. In this review, the results of clinical trials evaluating treatment of pre-school wheeze are discussed, with specific emphasis on the characteristics and phenotype of the study populations. Evidence suggests that systemic corticosteroids are not beneficial for the treatment of mild-to-moderate exacerbations of pre-school wheeze, irrespective of phenotype. The use of high-dose intermittent inhaled corticosteroid treatment cannot be recommended because of unacceptable side effects. Treatment with regular inhaled corticosteroids and leukotriene antagonists offer modest benefit, but neither treatment reduces hospitalisation rates. There is currently some evidence for a phenotype-specific effect of treatment. Phenotype-directed treatment of pre-school wheeze is currently limited by our ability to accurately differentiate between clinically useful phenotypes.

Asthma-IV: Diagnostic and Management
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
Asthma I: Introduction
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.
Asthma-II: Pathophysiology and Classification
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:
