Background Celiac disease (CD) and rheumatoid arthritis (RA) are multisystem autoimmune diseases affecting 1% of general populationa. Both diseases share genetic and immunological features. Aim In this retrospective study, we aim to determine the frequency of auto‐antibodies of RA in adult patients with CD. Materials and methods Seventy seven adult patients with active CD were included in the present study. Ninety healthy blood donors (HBD) served as control group. Anti‐cyclic citrullinated peptides antibodies (CCP‐Ab) and rheumatoid factors (RF; IgA, IgG and IgM) were determined by enzyme linked immunosorbent assay (ELISA) for patients and control group. For statistical analysis, we used Chi‐square or Fisher's exact test. Results Our study included 77 adult patients with active celiac disease (57 female, 20 male). Twenty‐four (31.2%) active celiac patients and 7 (7.8%) blood donors had CCP‐Ab or RF (31.2% vs 7.8%, p < 10–4). Only two patients (2.6%) had both CCP‐Ab and RF. IgA was the predominant isotype of RF in celiac patients ( n = 18; 23.4%) while none of healthy blood donors had RF‐IgA (23.4% vs 0.0%, p < 10–4). Conclusion The current study has shown that CD is associated with a high frequency of RF‐IgA suggesting that celiac patients could be at a higher risk of developing RA.
