Pulmonary function abnormalities in Sjogren's syndrome and the sicca complex

Abstract

The frequency of pulmonary involvement in a group of 20 patients with Sjogren's syndrome or the sicca complex was evaluated with pulmonary function studies. In 12 patients pulmonary functional abnormalities were demonstrated. The most common abnormality was airway obstruction. Nine out of 13 patients with the limited variant of the disease (sicca complex) and three out of seven patients with the complete syndrome had abnormal pulmonary function.
