Elemental diet: a therapeutic approach in chronic inflammatory bowel disease.
The therapeutic effect of an elemental diet (Pepti 2000) and blended normal diet (placebo) was investigated in 43 out-patients with chronic inflammatory bowel disease (IBD); 24 with ulcerative colitis (UC) and 19 with Crohn's disease (CD), in a mild to moderate state of disease activity. A pilot study on healthy volunteers was executed to investigate palatability of the two diets. The patients were randomized in a double-blind study to the two diet regimes for 14 d. A simultaneous determination of laboratory data including plasma C3c split product and urinary excretion of 51Cr-EDTA was carried out together with a careful registration of the clinical symptoms and signs. No significant effect on the stage of clinical activity was seen in CD. A significant effect on clinical activity was obtained in both UC groups. The clinical improvement was primarily due to a decrease in number of bowel movements both in the elemental diet group and in the group of patients on the blended normal diet. The gross appearance of rectal mucosa did not improve during the study period in the Pepti 2000 or in the placebo group. The concentration of complement split products in plasma remained unchanged. 51Cr-EDTA excretion, as an expression of a leaky bowel mucosa, also remained unchanged. It was concluded that an effect on inflammation could not be demonstrated even if both diets seem to have a beneficial effect on the stage of clinical activity, especially diarrhoea, in patients with UC.
