Objective: To review the diagnostic and prognostic value of anti-mutated citrullinated vimentin (MCV) in rheumatoid arthritis, taking into account the already available serology. Methods: Medline was searched via PubMed (1966 to May 2008) for anti-MCV and related terms, arthritis and arthropathies. Studies with anti-MCV, arthritis/arthropathy, and primary data on diagnosis and/or prognosis were included. Their methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) instrument for diagnostic studies and the modified Hayden list for prognostic studies. Results: Of 14 eligible studies, 11 included diagnostic data and 3 included prognostic data. No study evaluated anti-MCV as an added diagnostic test to the already available anti-cyclic citrullinated peptide (CCP) and rheumatoid factor serology. One study included the optimal patient spectrum resulting in a sensitivity of 0.59 and specificity of 0.98. A total of 10 diagnostic case-control studies using the same anti-MCV kit showed a sensitivity of 0.64-0.84 and a specificity of 0.79-0.96. This almost equalled the performance of anti-CCP in the same studies. The prognostic evaluation of anti-MCV was limited by differences in study methodology, outcome and statistical modelling. Individual studies showed moderate associations for anti-MCV and radiological progression with the strength of the association comparable to that of anti-CCP. Conclusions: Study heterogeneity, choice of study population and methodological limitations limited overall conclusions about the true diagnostic and prognostic test performance of anti-MCV. Evidence from the diagnostic case-control studies suggests that anti-MCV may be used as an alternative for anti-CCP.
