Short article: Absence of serological rheumatoid arthritis biomarkers in inflammatory bowel disease patients with arthropathies.

Abstract

OBJECTIVE:

Biomarkers that are associated with future progression to rheumatoid arthritis (RA) and joint destruction have been discovered previously in patients with arthralgia. The present study examined these RA biomarkers in inflammatory bowel disease (IBD) patients with arthropathies.

PATIENTS AND METHODS:

Sera from 155 IBD patients with and 99 IBD patients without arthropathies were analyzed for immunoglobulin (Ig) M rheumatoid factor (RF), IgA-RF, anti-cyclic citrullinated peptide 2, anti-cyclic citrullinated peptide 3.1, and anti-carbamylated protein antibody positivity using enzyme-linked immunosorbent assays. The prevalence of the autoantibodies in the IBD patients was compared with the prevalence in RA patients.

RESULTS:

No differences were found in biomarker positivity between IBD patients with and without arthropathies. Significantly more biomarker positivity (P<0.001) was observed in RA patients compared with IBD patients with arthropathies. Also, smoking turned out to be significantly associated with positivity for IgM-RF or IgA-RF.

CONCLUSION:

Our findings suggest that there is no apparent clinical value in the detection of RA biomarkers in serum of IBD patients to help identify arthropathies.
