Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. Although in most asthmatic patients there is a correlation between the level of airway inflammation and the severity of symptoms, in patients with difficult to treat asthma there is often discordance between symptoms and inflammation. Clinicians need easy noninvasive and affordable biomarkers for the recognition of asthmatic inflammation in order to provide optimal and effective therapeutic interventions to their patients.

Data Sources:
We have performed a search on PubMed using the keywords asthma therapy, biomarkers, exhaled NO, induced sputum and inflammation.

Study Selections:
We focused on papers providing results that could be useful in clinical practice. Results: In this review we focus on the treatment of asthmatic patients using biomarkers in biological samples collected using semi-invasive (serum and induced sputum) and non-invasive (exhaled breath condensate, and exhaled air) procedures.

Asthma research is shifting from studying symptoms expression, lung function and response to medication, to cellular profile, protein analysis and genetic markers, possibly combined with clinical measures. Single biomarker approaches to phenotype asthma do not seem to be accurate and therefore studies combining multiple known biomarkers are needed.
