This is a pilot study being conducted in patients with mild-moderate IBD as assessed by Crohn's disease activity index or Mayo Score. Our studies indicate that some ganglioside species prevent proinflammatory stimuli and prevent disruption of integrity of tight junctions between enterocytes, normalizing transepithelial electrical resistance in inflamed cells. Feeding ganglioside to rats prevented lipopolysaccharide-stimulated decrease in cellular tight junction protein occludin. Low level of GD3 ganglioside in the intestinal mucosa is associated with degradation of tight junction proteins. Increasing the GD3 content of the intestinal mucosa thus reduces the degradation of tight junction proteins improving the integrity of the brush border and improving the deleterious changes occurring in intestinal permeability. Improving intestinal integrity in subjects with IBD is important to manage diarrhea, infection, penetration of allergens, and malnutrition. Research in progress from our group demonstrates that dietary ganglioside decreased level of pro-inflammatory prostaglandin E2 in healthy human subjects and those with Crohn's disease. Also, daily consumption of ganglioside was very effective in improving the Crohn's disease activity index by an average of 43% over an eight-week study period.
