Official Title

Characterization of Mucus Solids Concentration in Patients With Bronchiectasis: Cross-sectional Study

Brief Summary

      There is a need for biomarkers that can rapidly and sensitively detect therapeutic benefits
      of therapies designed to "rehydrate" airways and monitor disease severity and progression. In
      this study the investigators will evaluate the stability of mucus concentration in patients
      with bronquiectasis (CF and NCBF) and its ability to respond to acute exacerbations in order
      to assess whether it can be a good candidate for biomarker.

Detailed Description

      Prospective cross-sectional study of repeated measurements. The recruitment will be performed
      in 3 different cities of Spain: Zaragoza, Barcelona and Murcia.

      Subjects will be asked to repeatedly collect spontaneous and induced sputum samples in both
      stable and exacerbated conditions. All samples will be collected autonomously by patients in
      their homes after they have been instructed and supervised. Hypertonic saline nebulization
      will be used for sputum induction.
