TY - JOUR T1 - Serum KL-6 level as a monitoring marker in a patient with pulmonary alveolar proteinosis JF - Thorax JO - Thorax SP - 809 LP - 811 DO - 10.1136/thx.53.9.809 VL - 53 IS - 9 AU - Masamitsu Nakajima AU - Toshiaki Manabe AU - Yoshihito Niki AU - Toshiharu Matsushima Y1 - 1998/09/01 UR - http://thorax.bmj.com/content/53/9/809.abstract N2 - A raised serum level of KL-6 is known to exist in active pulmonary fibrosis and KL-6 may be produced and secreted by type II pneumocytes. A case is described of pulmonary alveolar proteinosis with high serum KL-6 levels. The serum KL-6 level decreased after whole lung washing and correlated with symptoms, opacities on the chest radiograph, and arterial blood gas measurements. The serum KL-6 level may represent a useful marker for pulmonary alveolar proteinosis. ER -
