Abstract:
Objective To investigate the clinical diagnostic value of anti-cyclic citrullinated peptide(CCP)antibody,anti-mutated citrullinated vimentin(MCV)antibody and 25-hydroxyvitamin D[25-(OH)D]in rheumatoid arthritis(RA)patients.Methods A total of 466 patients with RA who were admitted the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from August 2016 to November 2021 were included in RA group,100 patients with other autoimmune diseases and metabolic diseases without RA were included in non-RA group,100 healthy subjects were included in control group.Serum anti-CCP antibody,anti-MCV antibody and 25(OH)D were detected in three groups.Receiver operating characteristic curve was drawn to analyze the diagnostic efficacy of anti-CCP antibody,anti-MCV antibody and 25(OH)D in RA.The correlation between anti-MCV antibody and clinical indexes in RA patients was analyzed.Results Serum anti-MCV antibody and anti-CCP antibody in RA group were significantly higher than those in non-RA group and control group(P<0.05).The serum 25(OH)D level in RA group was significantly lower than that in control group(P<0.05).The area under the curve(AUC)of anti-CCP antibody,anti-MCV antibody and 25(OH)D for the diagnosis of RA were 0.74,0.81 and 0.75,respectively.The AUC for the combined diagnosis of RA was 0.90,the sensitivity was 83.70%,and the specificity was 82.40%.Anti-MCV antibody was positively correlated with erythrocyte sedimentation rate and C-reactive proten(r=0.66,0.64,P<0.05),and negatively correlated with complement C3 and C4(r=-0.69,-0.62,P<0.05).Conclusion Anti-CCP antibody,anti-MCV antibody and 25(OH)D have good sensitivity and specificity for the diagnosis of RA,and anti-MCV antibody was helpful for the diagnosis of the disease activity.
