Abstract:
Objective To investigate the relationship between anti mutated citrullinated vimentin (MCV) antibody, anti-cyclic citrullinated peptide (CCP) antibody with disease activity and bone erosion in patients with rheumatoid arthritis (RA), so as to provide evidence for clinical diagnosis and treatment. Methods The anti-CCP antibody and anti-MCV antibody were detected using the enzyme-linked immune adsorption method (ELISA) for 634 patients with RA. At the same time, the clinical and laboratory data were collected, and the X-ray images of hands or feet were taken. Disease activity score (DAS)28 score was calculated, and all patients were divided into high disease activity group, moderatedisease activity group, low disease activity group and stable disease group on the basis of the DAS28 score. We analyzed the relationship between the degree of anti MCV, anti CCP antibodies, and disease activity of patients by Spearman correlation. And anti CCP, anti MCV antibodies, erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) of these patients were compared at different period of bone erosion and disease activity by the Wilcoxon rank sum test and nemenyi. Results ① Positive correlation could be detected between anti-MCV antibody and ESR, CRP, number of tender joint, DAS28 score (r=0.115, P=0.004; r=0.120, P=0.003; r=0.124, P=0.002; r=0.085, P=0.032), and anti CCP antibody had no correlation with these index. The anti MCV antibodies in high disease activity group [694 (156, 1 000)] U/ml, and moderate activity group [911 (190, 1 000)] U/ml were higher than that of the low disease activity [248(150, 731)] U/ml or stable group [275(62, 928)] U/ml (U=2.29, P=0.023;U=2.25, P=0.024; U=2.45, P=0.014; U=2.4, P=0.018), and anti CCP antibody in the moderate disease activity group [499(180, 1 370)] U/ml was higher than low disease activity group [297(83, 574)] U/ml and stable group [187(67, 1 153)] U/ml (U=2.53, P=0.012; U=2.22, P=0.026). ②The anti MCV, anti CCP antibody in the bone erosion group were higher than those without bone erosion group (U=4.64, P<0.01;U=2.69, P=0.007). The anti MCV antibodies in stage Ⅱ[722(259, 1 000)] U/ml and Ⅲ group [714 (216, 1 000)] U/ml was significantly higher than that in stage Ⅰ [316(98, 1 000)] U/ml(U=3.46, P<0.01; U=4.28, P<0.01). The anti CCP antibody level in stage Ⅱ [394(180, 1 000)] U/ml and Ⅲ[391(181,1305)] U/ml was higher compared with stage Ⅰ[277 (98,898)] U/ml (U=1.99, P=0.046; U=2.92, P=0.004), and that in phase Ⅲ was higher than Ⅳ [218(71, 911)] U/ml (U=2.06, P=0.041). Conclusion Compared with anti-CCP antibody, anti-MCV antibody is closely related with disease activity, and has a better predictive value for bone erosion. Patients with higher ESR and CRP are more susceptible to bone erosion.
