ABSTRACT
Rheumatoid arthritis (RA) is a chronic autoimmune disease with multiple morbidity burdens. Early diagnosis of RA is the main key in management and prevention of disease complications. Much research nowadays is looking for a serological marker with high accuracy in diagnosis of early RA cases. Our aim in this study was to evaluate the role of anti-mutated citrullinated vimentin (anti-MCV) antibodies in the early diagnosis of RA. In addition to compare its diagnostic sensitivity and specificity with anti-cyclic citrullinated peptide antibodies (anti-CCP) and RF antibodies in early versus established RA patients. This prospective cross-sectional study included 80 participants:
40 RA patients (20 early RA patients and 20 established RA patients), 20 patients with other rheumatic diseases (as a disease control group), and 20 apparently healthy participants as normal controls. All participants underwent history taking, clinical examination (general, articular assessment and calculation of disease activity score (DAS28-ESR)) for RA patients, radiological and laboratory investigations (RF, anti-CCP2 and anti-MCV antibodies measurements by ELISA technique). The results showed that the mean values of anti-CCP2 and anti-MCV were significantly increased in RA cases compared to the control groups (p=0.00 and p=0.01, respectively). Anti-MCV had sensitivity and specificity of 63% and 83%, respectively for diagnosing of early RA at area under curve of 0.80 compared to sensitivity and specificity 37% and 100%, respectively for anti-CCP2. Also, both (anti-CCP2 and anti-MCV) had positive significant correlations with ESR (p < 0.001 and p=0.02, respectively), CRP (p=0.01 and p=0.02, respectively) and DAS 28 (p < 0.001 for both). In conclusion, our data indicated that anti-MCV antibodies may represent a valuable marker for diagnosis of early RA cases.
