Inferior endothelial function improved following optimisation of asthma control in children

Area of Science:

• Pediatric Pulmonology
• Cardiovascular Health
• Systemic Inflammation

Background:

• Asthma and cardiovascular disease (CVD) share links to chronic systemic inflammation.
• Endothelial dysfunction is an early marker of cardiovascular risk.
• The relationship between asthma control and cardiovascular health in children requires further investigation.

Purpose of the Study:

• To assess endothelial function in children with asthma compared to healthy controls.
• To evaluate the impact of inhaled corticosteroids (ICS) on endothelial function in children with uncontrolled asthma.

Main Methods:

• Physician-diagnosed asthma patients and matched healthy controls underwent endothelial function assessment.
• Measurements were repeated in uncontrolled asthmatics after ICS initiation/up-titration.
• Comparisons were made between uncontrolled asthmatics, controlled asthmatics, and healthy controls.

Main Results:

• Children with uncontrolled asthma exhibited significantly inferior endothelial function compared to healthy controls.
• Initiation or up-titration of ICS in uncontrolled asthmatics led to improvements in endothelial function.
• Improvements in lung function and asthma symptom control were also observed following ICS therapy.

Conclusions:

• Uncontrolled asthma is associated with impaired endothelial function in children.
• Inhaled corticosteroids (ICS) therapy can improve endothelial function, lung function, and asthma control.
• These findings support a significant relationship between asthma control and cardiovascular health in pediatric populations.
