Breath volatile organic compounds and inflammatory markers in adult asthma patients - negative results from the ALLIANCE cohort.
2020
Breathomics in asthma is a rapidly growing area of significant scientific interest, as indicated by a recently published review, two research articles, and their accompanying editorials in high impact pneumology journals [1–5]. The repeatedly observed associations between breath volatile organic compounds (VOCs) and sputum or blood inflammatory cells [2, 3] suggest that breathomics are on the brink of introduction as a valuable clinically tool. However, there are also major concerns about unresolved methodological issues and a general paucity of high-quality data [1, 6]. In this letter we detail our concerns with breath-omics based on data from a cohort of adult asthma patients with a broad spectrum of clinical phenotypes.
