Lung involvement in systemic sclerosis: role of high resolution computed tomography and its relationship with other pulmonary and clinico-serological features
Vol 28, Issue 3, 2014
Abstract
The study investigated the characteristic of interstitial lung disease in a large series of systemic sclerosis (SSc) patients by means of HRCT and the correlations between functional lung parameters, serological features and the extent of lung involvement evaluated by high-resolution computed tomography (HRCT). One hundred and seven SSc patients, consecutively investigated by means of HRCT, standard chest X-ray, and pulmonary function tests, were retrospectively evaluated. Chest radiogram and HRCT scores were strongly associated (Pearsons r=0.82, p<.0001); moreover, the first significantly correlated with spirometric parameters, even if weakly. Anti-Scl70 and anti-centromere antibodies were associated with higher (p=0.01) and lower HRCT score (p=0.0002), respectively. The extension of interstitial lung involvement in SSc evaluated with HRCT is directly proportional to functional lung parameters. HRCT, spirometry and DLco should be considered essential in the core-set of non-invasive diagnostic tools for the first-line assessment of scleroderma lung involvement.
