Exhaled volatile organic compounds (VOCs) for prediction of asthma exacerbation in children.

Objectives: To find possible relationship between asthma exacerbation and metabolomic profile of airways, assessed by non-invasive method - free volatile organic compounds (VOCs) in exhaled air in children.

Material And Methods: The study included 80 children aged 4-18 years with asthma: 42 children with a min. 3 asthma exacerbations in the past 12 months, and 38 children without a history of exacerbations in the past year.
