Abstrakt: | Introduction: Pulmonary complications in systemic sclerosis (SSc) significantly increase morbidity and mortality. Our aim was to determine the factors limiting exercise capacity in SSc patients with and without interstitial lung disease (ILD), and to identify and quantify abnormalities during exercise that might assist in clinical assessment of this complication. Methods: Fifteen patients with SSc and ILD (SSc-ILD) were compared with 10 patients with SSc without ILD and 9 age- and sex-matched normal volunteers. Subjects performed symptom-limited incremental treadmill exercise with online measurement of respiratory gas exchange, arterial blood gas sampling and measurement of neurohormones in venous blood. Results: Patients with SSc-ILD had lower exercise capacity than SSc patients without ILD or normal subjects (peak oxygen consumption (PV̇O Conclusions: SSc-ILD results in lower exercise capacity than SSc without ILD, and abnormalities of gas exchange are seen. The possible use of cardiopulmonary exercise testing to identify disease and quantify impairment in SSc-ILD merits further study.
