title: [Biomarkers in asthma].
abstract: Identifying new biomarkers in asthma is attractive but requires assessing their relevance and their reliability to clinical practice. Beyond fashion, the improvement in identification of new candidate biomarkers benefited of scientific and biologic progresses, biobanks and platforms robustly backed on longitudinal cohorts and registries. Paradoxically, the main issue is now to stress up the good question, in other words to correctly characterize the unmet needs in asthma that might benefit of a biomarker. Chronicity, variability, weakness of diagnostic tools and the heterogeneity of the disease are features of asthma claiming for identifying new biomarkers. Unmet needs in asthma encompass areas such as diagnosis, prognosis, management and follow-up, therapeutic guidance and phenotypic/endotypic identification. FEV1 is an available biomarker largely tested in asthma worth in most of these areas. Albeit, mandatory features required for a new biomarker to emerge, pro/con debates on those already existing and currently used methods for identifying new ones are worth explorations. We reviewed and summarized the current literature focusing biomarkers in asthma.
