OBJECTIVE: To investigate whether patients with rheumatoid arthritis (RA) have immunological or clinical evidence of gluten hypersensitivity.
METHODS: Antigliadin antibodies (AGA) and antireticulin antibodies (ARA) were determined in two groups of RA patients and in a control group of patients with spondylarthropathies. In the first group of 42 patients with recent-onset RA, AGA and ARA were studied longitudinally during a one-year follow up period. In the second group of 36 patients with advanced RA and various abdominal symptoms examined by upper gastrointestinal endoscopy, AGA and ARA were determined cross-sectionally.
RESULTS: Increased AGA (IgA or IgG) levels were found in 37% (29/78) of all RA patients compared to 12% (3/25) of controls. ARA positivity (IgG) was found in 4% (3/78) of RA patients and in none of the controls. AGA positivity was increased in patients with early RA compared to patients with advanced disease (48% vs. 25%) but the difference was not statistically significant. However, no true gluten hypersensitivity with positive AGA and ARA together with villous atrophy was observed.
CONCLUSION: Despite the increased AGA positivity found distinctively in patients with recent-onset RA, none of the RA patients showed clear evidence of coeliac disease. AGA positivity in early RA may indicate a role of the gut immune system in the initiation of RA.
