[Soluble interleukin 2 receptor (SIL-2R) in bronchoalveolar lavage fluid (BALF) of patients with sarcoidosis and atopic bronchial asthma]. / Rozpuszczalny receptor dla interleukiny 2 w popluczynach oskrzelowo--pecherzykowych (BALF) u chorych na sarkoidoze i astme oskrzelowa atopowa.

The aim of the study was assessment of sIL-2R in BALF in asthma and sarcoidosis patients. Forty three patients were enrolled in this study. Twenty eight with sarcoidosis (S) in different stages (I, II, III) and activity of disease: active (AS) or nonactive (NAS) and fifteen with atopic bronchial asthma (AO). BALF sIL-2R levels were measured in both groups. The level of sIL-2R was similar in sarcoidosis patients independently to activity of disease. Significantly lower level of sII-2R in BALF was observed in patients with AO in comparison to S, SII and NAS (p < 0.005). We didn't find significant differences in sIL-2R levels between AO and SI, SIII, AS.
