Guidelines for the management of obstructive airway diseases do not emphasize the measurement of bronchitis to indicate appropriate treatments or monitor response to treatment. Bronchitis is the central component of airway diseases and contributes to symptoms, physiological and structural abnormalities. It can be measured directly and reliably by quantitative assay of spontaneous or induced sputum. The measurement is reproducible, valid, and responsive to treatment and to changes in disease status. Bronchitis may be eosinophilic, neutrophilic, mixed, or paucigranulocytic (eosinophils and neutrophils not elevated). Eosinophilic bronchitis is usually a Th2 driven process and therefore a sputum eosinophilia of greater than 3% usually indicates a response to treatment with corticosteroids or novel therapies directed against Th2 cytokines such as IL-4, IL-5 and IL-13. Neutrophilic bronchitis which is a non-Th2 driven disease is generally a predictor of response to antibiotics and may be a predictor to therapies targeted at pathways that lead to neutrophil recruitment such as IL-8 (eg anti-CXCR2), IL-17 (eg anti-IL17) etc. Paucigranulocytic disease may not warrant anti-inflammatory therapy. Several novel monoclonals and small molecule antagonists have been evaluated in clinical trials with variable results and several more are likely to be discovered in the near future. The success of these agents will depend on appropriate patient selection by accurate phenotyping or characterization of bronchitis.

Guidelines for the management of severe asthma do not emphasize the measurement of the inflammatory component of airway disease to indicate appropriate treatments or to monitor response to treatment. Inflammation is a central component of asthma and contributes to symptoms, physiological, and structural abnormalities. It can be assessed by a number of endotyping strategies based on "omics" technology such as proteomics, transcriptomics, and metabolomics. It can also be assessed using simple cellular responses by quantitative cytometry in sputum. Bronchitis may be eosinophilic, neutrophilic, mixed-granulocytic, or paucigranulocytic (eosinophils and neutrophils not elevated). Eosinophilic bronchitis is usually a Type 2 (T2)-driven process and therefore a sputum eosinophilia of greater than 3% usually indicates a response to treatment with corticosteroids or novel therapies directed against T2 cytokines such as IL-4, IL-5, and IL-13. Neutrophilic bronchitis represents a non-T2-driven disease, which is generally a predictor of response to antibiotics and may be a predictor to therapies targeted at pathways that lead to neutrophil recruitment such as TNF, IL-1, IL-6, IL-8, IL-23, and IL-17. Paucigranulocytic disease may not warrant anti-inflammatory therapy. These patients, whose symptoms may be driven largely by airway hyper-responsiveness may benefit from smooth muscle-directed therapies such as bronchial thermoplasty or mast-cell directed therapies. This review will briefly summarize the current knowledge regarding "omics-based signatures" and cellular endotyping of severe asthma and give an overview of segmentation of asthma therapeutics guided by the endotype.
