Objectives: The aim of this study was to examine molecules in exhaled breath condensate( EBC) in comparison with BALF, and to clarify the clinical usability of EBC. Methods: EBC was collected from sixteen subjects suspected to have sarcoidosis just before BAL. The 40 different inflammatory molecules in EBC and BALF were analyzed by protein array. Results: BALF levels of 6 molecules including soluble tumor necrosis factor receptor type II (sTNF-RII) and regulated upon activation, normal T cell expressed and secreted (RANTES), and EBC levels of 13 molecules including sTNF-RII and RANTES were significantly correlated with percentage of lymphocyte in BALF (%Lym). We found significant correlations between levels of EBC and BALF in 16 out of 40 molecules. Levels of macrophage colony-stimulating factor( M-CSF), RANTES, TNF-α and sTNF-RII in EBC were significantly correlated with BALF. Their levels in EBC and BALF also were correlated with %Lym. Conclusion: Protein array, a highly sensitive approach allowed us to detect inflammatory molecules in EBC. Comprehensive analysis of EBC might be an equivalent to that of BALF., 弘前医学. 63, 2012, p.12-20}, pages = {12--20}, title = {Is Analysis of Exhaled Breath Condensate an Equivalent to Bronchoalveolar Lavage Fluid in Sarcoidos is Patients?}, volume = {63}, year = {2012} }
