Abstract BACKGROUND: Inulin and oligofructose promote selective growth of saccharolytic bacteria with low inflammatory potential. OBJECTIVE: To test the effect of oligofructose-enriched inulin in patients with active ulcerative colitis. DESIGN: Prospective, randomized, placebo controlled pilot trial. Eligible patients had been previously in remission with mesalazine as maintenance therapy or no drug, and presented with a relapse of mild to moderate activity. They were treated with mesalazine (3 g/day) and randomly allocated to receive either oligofructose-enriched inulin (12 g/day, p.o., n = 10) or placebo (12 g/day of maltodextrin, p.o., n = 9) for 2 week. Primary endpoint was the anti-inflammatory effect as determined by reduction of calprotectin and human DNA in faeces. RESULTS: Rachmilewitz score decreased in both groups, reaching statistical significance at day 14 (P < 0.05). Oligofructose-enriched inulin was well-tolerated and dyspeptic symptoms scale decreased significantly with active treatment but not with placebo. At day 7, an early significant reduction of calprotectin was observed in the group receiving oligofructose-enriched inulin (day 0: 4377 +/- 659 microg/g; day 7: 1033 +/- 393 microg/g, P < 0.05) but not in the placebo group (day 0: 5834 +/- 1563 microg/g; day 7: 4084 +/- 1395 microg/g, n.s.). Changes in faecal concentration of human DNA were not significant. CONCLUSION: In active ulcerative colitis, dietary supplementation with oligofructose-enriched inulin is well tolerated and is associated with early reduction in faecal calprotectin.
