Case study: Pediatrics, Management
A young girl continued to experience asthma symptoms despite being on an inhaled corticosteroid (ICS). FeNO testing revealed ongoing inflammation, leading to an adjustment in her treatment plan.
Last updated: September 2026
Gender/Age: Female under 12 years old
History: Four courses of prednisolone in the past two years, regular use of ICS with good adherence and inhaler technique
Despite good medication adherence and proper inhaler use, the patient continued to experience symptoms. Her parents were hesitant to increase her medication without a clearer understanding of her condition.
FeNO Test:Elevated levels, indicating ongoing eosinophilic airway inflammation despite current treatment
Inhaled Corticosteroid (ICS): Based on the elevated FeNO levels, her inhaled corticosteroid dose was increased.
Asthma Action Plan: The patient received a personalised asthma action plan and education on managing symptoms and handling emergencies.
FeNO testing uncovered persistent inflammation which allowed for an appropriate adjustment in treatment, leading to better asthma control and an improved quality of life.
