P577 Cost-effectiveness of episodic or maintenance infliximab versus standard treatment in an incidence cohort of Crohn's disease patients with 10-years follow-up

in all study groups (105.8% vs 114.3% RDA in normal controls; 88.7% vs 109.2% RDA in diseased controls, 100.4% vs 87.6% RDA in IBD. Conclusions: In this study IBD patients had a significantly lower Ca intake than healthy controls. In accordance to previous studies, gender and age, more than diagnosis, are relevant factors in determining inadequate Ca intake. The trend is more marked in IBD, especially in postmenopausal women. Selfreported lactose intolerance, leading to dietary restrictions, is the single major determinant of low Ca intake in all pts groups, irrespective to diagnosis, age and gender. Inadequate Ca intake is observed in about one third of IBD pts and represents an easily reversible risk factor for osteoporosis. The observation that celiac patients on low gluten diet have a Ca intake well over RDA, further supports the need for tailored nutrition advice also in ulcerative colitis and Crohn’s disease.
