Did you know our breath is a biomarker for asthma? There are many reports which indicate breath as a potential biomarker for many diseases. For the last few years the field of breathomics has grown and developed systematic reviews that are not only viable, but considered important enough for dissemination of high impact clinical research journals like the European Respiratory Journal.
Breath being a biomarker discovery platform has excited the medical world and there is a huge interest and demand for it, especially in cases of pediatric asthma, lung infection and fibrotic lung diseases. In this issue of the European Respiratory Journal, report a new systematic review covering breathomics in adult asthma. It has been found that reports of high quality remain relatively few, with only 22 studies meeting based broad inclusion criteria, of which most of the included studies investigated breath for disease identification, rather than more refined targets, such as asthma phenotyping or identification of treatment responses.
The most commonly stated aim in current studies is to investigate potential breath biomarkers that can be used in the diagnosis of asthma.
