Therefore, we sought to evaluate whether serum CCL18 levels at baseline could predict worsening of lung disease in SSc. In this prospective study, 83 SSc patients were analysed longitudinally over a 4-yr observation period for the risk of occurrence of combined deleterious events, defined as a 10% decrease from baseline of total lung capacity or forced vital capacity % predicted, or death, according to serum CCL18 at inclusion. Receiver operating characteristic (ROC) curve analysis was performed for prediction of events during the first year after inclusion. The best cut-off level of serum CCL18 for prediction of a combined event within the follow-up period was 187 ng·mL−1, with 53% sensitivity and 96% specificity (area under the ROC curve 0.86; p<0.001). After a mean±sd follow-up of 33.7±10.8 months, a higher rate of disease progression occurred in the group with serum CCL18 levels >187 ng·mL−1. The adjusted hazard ratio was 5.36 (95% CI 2.44–11.75; p<0.001). In summary, serum CCL18 is an accurate predictive biomarker for the identification of patients with a higher risk of subsequent scleroderma lung disease worsening. %U //www.qdcxjkg.com/content/erj/38/6/1355.full.pdf
