Functional evaluation of patients with progressive systemic sclerosis-associated diffuse parenchymal lung disease

Abstract

Background Interstitial lung diseases are common features in scleroderma that seem to add to the morbidity and mortality of the disease. Other complications that may occur with scleroderma are pulmonary hypertension. Aim to evaluate the functional status of patients with progressive systemic sclerosis-associated diffuse parenchymal lung disease. Methodology A total of 44 adult patients with a confirmed diagnosis of scleroderma were included. The disease severity was assumed by using the grading of the inter-incisor distance and finger-to-palm distance. Assessment of the chest high-resolution computed tomography (HRCT) was performed, and then functional assessment in the form of arterial blood gas, spirometry, 6-min walk distance, and echocardiography was performed. Results There were no significant differences between the scleroderma with diffuse parenchymal lung disease and those with normal HRCT regarding the measured and calculated parameters, except for the pulmonary artery systolic pressure, which was significantly higher in the normal HRCT group than those with interstitial lung disease.
