Oral nutritional supplementation is effective in the maintenance of remission in Crohn's disease.
BACKGROUND
Enteral feeding with either elemental or polymeric diets is an established primary therapy for active Crohn's disease. However, the role of supplementing normal food with elemental diet in the long-term management of Crohn's disease has hitherto not been explored.


METHODS
A series of 39 consecutive patients with Crohn's disease in clinical remission were studied. Of these, 21 patients (Group 1) received oral nutritional supplementation, taken in addition to their normal diet. Their outcome (relapse rate, Crohn's disease activity index, inflammatory markers) was compared with that of 18 patients (Group 2), who were maintained on a normal unrestricted diet over an observation period of 12 months.


RESULTS
A total of 17 patients (81%) tolerated the nutritional supplementation. On an intention-to-treat basis, 10 patients (48%) remained in remission for 12 months, compared to 4/18 (22%) patients in Group 2, p<0.0003. Their Crohn's disease activity index and CRP remained stable while their weight and body mass index improved during the period of nutrition therapy Seven patients in Group 1 and 14 in Group 2 relapsed at a mean of 7.4+/-0.9 and 6.2+/-0.4 months, respectively. The response to nutrition supplement was independent of age, sex, disease duration or location. Four patients (19%) were intolerant to enteral feeding.


CONCLUSIONS
Nutritional supplementation is safe, well tolerated and effective in the long-term management of patients with quiescent Crohn's disease.
