NCT02863406

Brief Summary

Comparison of dusting rate of bronchoalveolar lavage in healthy volunteers and patients suffering from sarcoidosis. Blind analysis of bronchoalveolar lavage with Optical Microscopy, Transmission Electron Microscopy and MicroAnalysis. For patients, comparison of bronchoalveolar lavage, pathological examination of biopsies (Optical Microscopy, Transmission Electron Microscopy and MicroAnalysis) and specific Professional and environmental questionnary. Healthy volunteers matched with patients regarding to age (every 10 years), sex and tobacco consumption (non-smoking, smoking less than 5 pack-year, smoking between 5 and 10 pack-year, smoking more than 10 pack-year)

Outcome Measures

Primary Outcomes (1)

  • Significant difference between dusting rate of bronchoalveolar lavage in healthy volunteers and patients suffering from sarcoidosis (analysis by Optical Microscopy, Transmission Electron Microscopy and MicroAnalysis).

    Procedure of bronchoalveolar lavage

Secondary Outcomes (3)

  • Correlation between mineral overload of bronchoalveolar lavage for patient suffering from sarcoidosis and data extracted from specific Professional and environmental questionnary

    Through study completion, an average of 1 year

  • Correlation between mineral overload of bronchoalveolar lavage for patient suffering from sarcoidosis and pathological examination of biopsies (analysis by Optical Microscopy, Transmission Electron Microscopy and MicroAnalysis).

    Through study completion, an average of 1 year

  • Interest of macrophagic dusting index

    Through study completion, an average of 1 year
