[Anticitrulin antibody and the extra-articular manifestations in rheumatoid arthritis].

A large proportion of rheumatoid arthritis (RA) patients develop extra-articular manifestations (EAM), which are associated with morbidity and early mortality. Anti cyclic citrullinated peptide (ACCP) antibody has proven to be highly specific for the diagnosis of RA, associated with severe joint damage and may have some role in the pathogenesis of EAM. The aim of this study was to determine the relationship between ACCP antibody and the presence of EAM in RA patients.
