Abstract:
Objective To investigate the detection of anti-cyclic citrullinated peptide(anti-CCP)antibody,alkaline phosphatase (ALP),glucose-6-phosphate isomerase(G6PI)and rheumatoid factor(RF)in the diagnosis of rheumatoid arthritis(RA).Methods Serum RF,anti-CCP body,ALP and G6PI were detected in 206 cases of RA,68 cases of other autoimmune diseases and 48 persons with the healthy physical examination,at the same time the erythrocyte sedimentation rate(ESR)was measured;the sensitivity and specificity of each indicator and the relationship between each index and RA′s diagnosis.Results The serum level of each index in the RA group was significantly higher than that in the other two groups(P <0.05).The sensitivity of RF,anti-CCP antibody and G6PI for diagnosing RA is similar;the specificity of anti-CCP body was highest(94.8%),RF was similar to G6PI;ALP with rela-tively lower sensitivity and specificity also reflected the potential of RA to some extent.Conclusion The simultaneous detection of serum RF,anti-CCP body,G6PI and ALP can improve the accuracy of early diagnosis of RA,reduce the missed diagnosis and guide the clinical treatment.
