Abstract

Abstract : Background: The aim of this study was to define the accuracy of transthoracic ultrasonography (TUS) in the diagnosis of pulmonary fibrosis. Objectives: The value of TUS in pulmonary fibrosis in a patients with connective tissue disease is not as yet established. The prospective study was conducted to analyzed ultrasound changes in patients with recognized pulmonary fibrosis by transthoracic lung sonography and compare it with high resolution computed tomography (HRCT). The aim of the study was to in determine the characteristics of ultrasound in patients with lung fibrosis. Methods: TUS was performed in 30 patients, average age 50 (SD 24), with diagnosed connective tissue disease and pulmonary fibrosis. The study group consisted of: systemic scleroderma (19), systemic vasculitides (3), mixed connective tissue disease (2), dermatomiositis (2), rheumatoid arthritis (1), ankylosing spondylitis (1), systemic lupus erythematosus (1), Sjogren's disease (1). Pulmonary fibrosis was confirmed by HRCT. The study group was compared with control group (50 subjects) with normal X-ray and no history in the direction of lung diseases. Results: In TUS has been reported: irregular pleural line - in 100% (0% in the control group, p<0.001), fragmented pleural line - in 77% (0% in the control group, p<0.001), blurred pleural line - in 52% (0% in the control group, p<0.001), thickened pleural line – in 23% (0% in the control group, p<0.001), artifacts of B lines less than three in one intercostal space - in 23% (0% in the control group, p<0.05) and more than four B lines in one intercostal space - in 69% (0% in the control group, p<0.001), and previously unrecognized artifact called the Am line- in 38% (0% in the control group, p<0.001). Conclusions: This study indicates the possibility of the diagnosis of pulmonary fibrosis using transthoracic sonography. Disclosure of Interest: None declared DOI: 10.1136/annrheumdis-2014-eular.3818
