Objective: Non-steroidal anti-inflammatory drugs (NSAID) can induce enteropathy. Aspirin ingestion is associated with a lower small-intestinal inflammation than other NSAID. Faecal calprotectin concentrations have recently been proposed as a simple non-invasive test to identify NSAID enteropathy. The aim of our pilot study was to evaluate calprotectin concentrations in patients on treatment with low-dose aspirin.
Methods: Twenty-two patients on prophylactic treatment with aspirin were recruited. Twenty-five healthy volunteers were enrolled as a control group. Faecal calprotectin concentrations were determined by enzyme-linked immunosorbent assay. Statistical analysis was performed by t-test for unpaired data.
Results: The mean faecal calprotectin concentration in patients (57.95+/-44.28 microg/g) did not show significant differences compared with controls (45.76+/-26.45 microg/g; P=0.251).
Conclusions: We found that low-dose aspirin does not induce an increase in faecal calprotectin increase.
