Anti-mutated citrulline vimentin antibodies may be higher in Ankylosing spondylitis, but may not have a role in diagnosing disease and may not be associated with disease severity

Özet

OBJECTIVE: Ankylosing spondylitis (AS) is a rheumatologic disease with severe morbidity and mortality. Many studies in the literature showing that serum antibodies against anti-mutated citrullinated vimentin (anti-MCV ab) can be elevated in rheumatoid arthritis (RA) patients. However, there is little data in the literature about the levels of anti-MCV antibodies in AS patients. We designed the study to evaluate the role of anti-MCV antibody in the diagnosis of AS and to investigate whether it is associated with disease activity parameters. METHODS: There were three separate groups in our study. The number of participants in these groups is 60 patients in the AS group, 60 patients in the RA group, and 50 healthy participants in the control group. The anti-MCV ab levels of the participants were measured by enzyme-like immune assay method. We compared anti-MCV levels between groups. We then evaluated its role in the diagnosis of AS and evaluated its relationship with disease activity parameters. RESULTS: The anti-MCV antibody levels of both AS (p=0.006) and RA (p>0.001) patients were found to be significantly higher than controls. Anti-MCV antibody was higher than predefined threshold level (20 IU/mL) in 4 of 60 (6.7%) AS patients. Anti-MCV levels are similar in patients with or without a-acceptable symptom state (PASS). There is also no appropriate antiMCV cutoff level with respect to PASS and a highly sensitive and specific level for diagnosis of AS. CONCLUSION: Although AS patients has higher anti-MCV levels than controls, it may have a limited ability to AS diagnosis and to predict severity of the disease.
