title: [Increased closing volume in asymptomatic respiratory sarcoidosis].
abstract: In 21 patients with asymptomatic respiratory sarcoidosis, 11 with hilar lymph node enlargement (stage I) and 10 with both hilar and lung involvement (stage II), pulmonary function tests revealed that the closing volume was increased as compared with control values obtained from healthy individuals of the same age and smoking habits. The difference was statistically significant but more pronounced in stage II patients than in stage I patients. Other function tests were normal (VC, FEV1, MMF, RV, TLC, DLCOSB).
