Abstract
AbstractObjectivesTo investigate the clinical value of detecting anti–mutated citrullinated vimentin (anti-MCV), anti-citrullinated peptide (anti-CCP), red-blood-cell distribution width (RDW), and 25-hydroxyvitamin D (25-[OH]D) in the diagnosis of rheumatoid arthritis (RA).MethodsWe enrolled 119 patients with RA, 114 control individuals without RA (disease controls), and 40 healthy controls in our study (Han Chinese). Anti-CCP and anti-MCV were detected by enzyme-linked immunosorbent assay (ELISA), 25-(OH)D was detected by electrochemical luminescence, and RDW was calculated by erythrocyte parameters detected via the electric resistance method.ResultsThe serum levels of anti-CCP and anti-MCV in RA were higher than those in disease controls and healthy controls (P <.01). The areas under the curve (AUCs) of anti-MCV, anti-CCP, RDW, and 25-(OH)D were 0.857, 0.890, 0.611, and 0.569 respectively (P <.05). In various combinations of indicators, when RDW, 25-(OH)D, and anti-CCP; or RDW, 25-(OH)D, anti-CCP, and anti-MCV were connected in parallel, the sensitivity was the highest (all 94.1%). Also, when RDW, 25-(OH)D, anti-CCP, and anti-MCV were connected in series, the sensitivity was the lowest (13.4%).ConclusionsAnti-CCP and anti-MCV are ideal indices for RA diagnosis. Also, in combination with RDW and 25-(OH)D, the diagnostic level will be improved, as well as the sensitivity and specificity, which is significant for the differential diagnosis of RA.
