附摘要：Abstract Objective Antibodies against citrulline-containing epitopes, such as antiperinuclear factor (APF), antikeratin antibodies (AKA), antifilaggrin antibodies, and anticyclic citrullinated peptide (anti-CCP) antibodies, are specific in rheumatoid arthritis (RA). Detection of APF, AKA, and anti-CCP has been widely used in clinical practice. However, studies on combined detection of these anti- citrullinated protein antibodies (ACPA) in the significance of diagnosing RA have been limited. We aimed to detect APF, AKA, and anti-CCP antibodies and to evaluate the significance of combined detection of these ACPA in RA. Methods A total of 551 patients with arthritic disorders, 304 with RA and 247 with other rheumatic diseases, were selected at the Department of Rheumatology and Immunology during the past 2 years. AKA and APF were tested by indirect immunofluorescence assay. Anti-CCP was detected using the second-generation ELISA kit. Results The sensitivities of anti-CCP, AKA, and APF tests for RA were 76.2%, 43.4%, and 34.5%, respectively, while the specificities were 96.0%, 98.4%, and 99.6%. The combination of anti-CCP, AKA, and APF positivity had the highest specificity (100%), but it yielded a low sensitivity (28.3%). When 2 of the 3 ACPA were positive, the sensitivity and specificity were 48.4% and 99.2%, respectively. When either anti-CCP or AKA or APF was positive, sensitivity increased to 77.3%, but specificity decreased to 94.7%. Conclusion Anti-CCP was the most valuable marker in the diagnosis of RA, among the 3 ACPA. Combined detection of anti-CCP, AKA, and APF did not increase the diagnostic capability for RA.
