The goal of this prospective study was to assess non-steroidal anti-inflammatory drug (NSAID)-induced enteropathy in patients with rheumatoid arthritis (RA) or osteoarthritis (OA) by means of non-invasive wireless capsule enteroscopy. A total of 143 patients (74 with RA, 69 with OA) treated with NSAIDs (>1 month) and 42 healthy volunteers were included.

All subjects underwent capsule endoscopy, laboratory tests and filled in questionnaires. The severity of small bowel injury was graded as: mild (red spots or sporadic erosions), moderate (10-20 erosions) or severe (>20 erosions or ulcers).

Capsule endoscopy identified small bowel lesions in 44.8 % of patients (mild 36.4 %, moderate 3.5 % and severe in 4.9 %). Mild non-specific lesions were found in 11.9 % healthy volunteers.

There was a significantly higher prevalence of enteropathy in RA (56.8 %) compared to OA (31.9 %, p < 0.01). A significant difference between NSAID users (RA and OA) with and without enteropathy was observed in erythrocytes (p < 0.01), the leucocyte count (p < 0.05), haemoglobin (p < 0.05), haematocrit (p < 0.05), serum albumin (p < 0.01) and erythrocyte sedimentation rate (p < 0.05).

No relationship was found between enteropathy and dyspepsia, gender or age. NSAID therapy is associated with a significant risk of small bowel injury.

The risk is significantly higher in RA patients suggesting a possible influence of the underlying disease.
