Question: Are nitric oxide , IL-6 and IL-13 increased in the exhaled breath condensates of children with allergic rhinitis?
Answer: Despite local application, the intranasal allergen challenge increased IL-13/EBC concentration in the AR children. As EBC reflects the status of lower airway segments, our observation may support the 'united airways' hypothesis, suggesting a functional link between the upper and lower airways.
A:
yes
