Insights

Inhaled corticosteroids are linked to higher ADHD odds in younger children with asthma. No significant association was found in older children or with oral corticosteroid use alone.

Area of Science:

  • Pediatric pulmonology
  • Child psychiatry
  • Pharmacovigilance

Background:

  • Asthma is a common chronic respiratory disease in children.
  • Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder.
  • Corticosteroids are frequently used to manage asthma, with varying administration routes.

Purpose of the Study:

  • To investigate the association between corticosteroid use and ADHD in pediatric asthma patients.
  • To explore how administration routes (inhaled vs. oral) and asthma severity influence this association.
  • To examine age-related differences in the impact of corticosteroids on ADHD.

Main Methods:

  • A population-based, cross-sectional analysis using the Kids Inpatient Database (2016, 2019).
  • Included pediatric patients aged 5-20 years with asthma.
  • ICD-10-CM codes identified corticosteroids use, asthma, and ADHD; logistic regression and IPW controlled for confounding.

Main Results:

  • In children aged 5-11, inhaled corticosteroids were associated with higher ADHD odds in moderate-to-severe asthma (aOR 1.46-1.61).
  • Combined inhaled and oral corticosteroid use showed significantly higher ADHD odds in severe asthma (aOR 4.85).
  • No significant association between corticosteroid use and ADHD was observed in asthmatic children aged 12-20 years.

Conclusions:

  • Inhaled corticosteroids are positively associated with ADHD in younger children (5-11 years) with moderate to severe asthma.
  • This association was not observed in older children (12-20 years) with asthma.
  • Findings highlight potential age-specific effects of inhaled corticosteroids on neurodevelopment in pediatric asthma.

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

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...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

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...

Antiasthma Drugs: β2-Adrenoceptor Agonists

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
