Insights

Sleep-disordered breathing (SDB) in children with asthma is linked to allergic rhinitis, tonsillitis, and reflux. SDB and not taking medication regularly are risk factors for poor asthma control.

Area of Science:

  • Pediatric Pulmonology
  • Sleep Medicine
  • Asthma Research

Background:

  • Sleep-disordered breathing (SDB) is a potential contributor to suboptimal asthma management in pediatric populations.
  • Identifying SDB risk factors and its impact on asthma control is crucial for effective treatment strategies.

Purpose of the Study:

  • To determine the risk factors associated with SDB in children diagnosed with asthma.
  • To evaluate the influence of SDB on the control levels of asthma in this cohort.

Main Methods:

  • A cross-sectional study was conducted involving 397 asthmatic children from June 2020 to August 2021.
  • Data collection included validated questionnaires: the Pediatric Sleep Questionnaire-Sleep-Related Breathing Disorder, Childhood Asthma Control Test, and Test for Respiratory and Asthma Control in Kids.

Main Results:

  • The prevalence of SDB among children with asthma was 21.6%.
  • Identified risk factors for SDB included allergic rhinitis, chronic tonsillitis, gastroesophageal reflux, adenoid hypertrophy, recurrent respiratory infections, and a family history of snoring.
  • Poor asthma control was observed in 19.6% of participants, with SDB and irregular medication use identified as significant risk factors.

Conclusions:

  • Allergic rhinitis, chronic tonsillitis, gastroesophageal reflux, adenoid hypertrophy, recurrent respiratory infections, and a family history of snoring are independent risk factors for SDB in children with asthma.
  • SDB and inconsistent medication adherence are independent risk factors for poor asthma control in this population.

Asthma-I: Introduction01:29

Asthma-I: Introduction

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...

Asthma-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

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:

Other Pulmonary Disorders01:17

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

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.
