Bronchoscopy and bronchoalveolar lavage findings in crosscountry skiers with and without "ski asthma" M. Sue-Chu*, L. Larsson+, T. Moen**, S.I. Rennard{, L. Bjermer* Bronchoscopy and bronchoalveolar lavage findings in cross-country skiers with and without "ski asthma". M. Sue-Chu, L. Larsson, T. Moen, S.I. Rennard, L. Bjermer. #ERS Journals Ltd 1999. ABSTRACT: Bronchial hyperresponsiveness to methacholine with asthma-like symptoms ("ski asthma") is frequent in elite cross-country skiers. To further the understanding of "ski asthma", 10 nonasthmatic, nonatopic controls and 30 adolescent elite skiers were investigated by bronchoscopy and bronchoalveolar lavage (BAL). Nine skiers were atopic without allergy symptoms. Compared with controls, the macroscopic inflammatory index in the proximal airways in skiers was three-fold greater (median (interquartile range) 3.0 (2.0±5.0) versus 1.0 (0.8±2.3), p=0.008). In the BAL fluid, skiers had significantly greater total cell (p
