Smoking produces substances that activate proinflammatory, prothrombotic and
vasoconstrictive mediators via posttranslational carbamylation of proteins. As a
new consequence of carbamylation, induction of anti-carbamylated autoantibodies
were observed in rheumatoid arthritis (RA) patients, sometimes prior to onset of
the disease. The overall aim of this study was to characterize the reactivity of
different isotypes of autoantibodies against carbamylated antigens of vimentin in
relation to established rheumatoid factor (RF), anti-citrullinated protein
antibodies (ACPA) and markers of disease activity in a so far largely
uncharacterized population of Latin American (Cuban) patients with RA. Antigenic
properties of carbamylated vimentin as well as vimentin peptides were analyzed in
101 patients with RA, 50 disease controls and 51 healthy controls. The diagnostic
performance was compared with established commercial ELISA rheumatoid factor,
anti-cyclic citrullinated peptide antibodies of second generation (anti-CCP2) and
anti-mutated citrullinated vimentin (anti-MCV) antibodies. Prevalence of anti-MCV
IgG (86 %), anti-carbamylated vimentin (carbVIM) IgG (77 %) and anti-carbamylated
MCV (carbMCV) IgG antibodies (65 %) was higher than the classical RF IgM (60 %)
and anti-CCP2 IgG (52 %) in this RA cohort. Of note, smoking status was
associated with positive IgG antibody reactivity against CCP2 in 75.0 % and
against MCV in 90 % of patients. Furthermore, IgM antibody response against
carbMCV and carbVIM was observed in 80 and 90.0 % of smokers, respectively. Due
to a high sensitivity of the IgM antibody isotype of anti-carbVIM of 85.2 %, the
combination of ACPA with anti-carbVIM IgM provided the best diagnostic
performance so far achieved in a RA cohort of this ethnic origin. We demonstrate
a high prevalence of anti-carbVIM antibodies and correlation with smoking in
Latin American (Cuban) RA patients. Anti-carbVIM IgM represents an useful
marker in ACPA-negative patients and, in combination with ACPA IgG assays,
optimizes the strategy for autoantibody testing.
