title: [Chemokine RANTES in bronchoalveolar lavage fluid(BAL)from two different lung segments indicated by high resolution tomography (HRCT) in patients with sarcoidosis].
abstract: In 28 non-smoking patients with sarcoidosis (14 males, 14 females aged 19-51) the concentrations of cytokine RANTES were estimated in BAL fluid from two different lung segments: with the most (s.A) and with the least (s.B.) extensive involvement estimated by high resolution computed tomography (HRCT). In examined subjects 12 patients showed homogeneous distribution of HRCT changes (HD) in lung parenchyma and 16 showed nonhomogeneous distribution of HRCT changes (ND) with domination of pathological changes in upper lobes. Eleven healthy volunteers served as controls. In BALF from s.A and sB the significantly higher concentrations of RANTES were observed in comparison with control group (14.4 and 10.9 pg/ml vs 3.6 and 3.4 pg/ml respectively). In group (ND) in BALF from s.A (from upper lobes--the most occupied by HRCT changes) the concentrations of RANTES were significantly higher than in BALF from s.B (from lower lobes with the least involvement estimated by HRCT). RANTES concentrations in BALF from s.A and s.B positively correlated with lymphocytes count, lymphocytes CD3, CD4 and HLA-DR+ and correlated negatively with diffusing capacity in sarcoid patients. Our results suggest the significant role in pathogenesis of sarcoidosis and in alveolitis process enhancement.
