Abstract:
Objective:To investigate the relationships between the expression levels of chemokines CCL19 and CCL21 in serum of patients with RA and interstitial lung disease,as well as the correlation between the chemokines and the clinical parameters.Methods:Patients hospitalized in the First Hospital of China Medical University from May 2016 to March 2017 were enrolled.Serum levels of CCL21 and CCL19 in the 62 patients with RA,among them,34 cases without pulmonary interstitial lesions while 28 cases with lung interstitial diseases,18 cases ⅡP and 20 health control were detected with enzyme-linked immunosorbent assay (ELISA).One-way ANOVA,LSD-t test,Kruskal-Wallis test,Pearson and Spearman correlation analysis were used for statistical analysis.Results:The levels of CCL21 and CCL19 were both higher in the RA patients than the health controls(P＜0.05;P＜0.01),The concentrations of CCL21 in serum of the RA patients with ILD were higher than thoes without ILD,higher than the health controls (P＜0.05;P＜0.01),serum levels of CCL21 in the ⅡP patients were higher than the health controls (P＜0.01),too.The serum levels of CCL21 in men were higher than women(P＜0.05).Serum CCL21 levels were negatively correlated with albumin and BMI(r=-0.280,P＜0.05;r =-0.605,P＜0.05).Levels of CCL19 were negatively correlated with the levels of C4 (r =-0.326,P＜0.05),and positively correlated with the levels of D-Dimer(r =0.592,P＜0.05).Conclusion:Chemokines CCL21 and CCL19 are highly expressed in serum of patients with RA,they may be involved in the pathogenesis of RA.Furthermore,CCL21 may has a correlation with the lung interstitial lesion in RA.
