Su2093 Glucagon Like Peptide-2 Production and Sensitivity in Infants Post-Resection or Gastroschisis

G A A b st ra ct s enhanced microbial fermentation of dietary fiber and dysregulation of choline metabolism. The OPLS-DA model constructed based on samples collected post DI (R2X=30.7%, Q2Y= 0.37) showed higher concentrations of glutamate and 6-aminosalicylic acid in AA compared with AF. Microbial data acquired using HITChip was integrated with fecal profiles using OPLS. At the phylum level, 2 out of 22 identified phyla were significantly correlated with fecal profiles, which are Cyanobacteria and uncultured Mollicutes significantly correlating with fecal glutamate and valerate. By statistically integrating the fecal metabonome and the 130 microbial genus, Bacteroides vulgates et rel. and Bacteroides plebeius et rel. were observed to be correlated with choline, whereas Uncultured Clostridiales II was correlated with pyroglutamate. Uncultured Mollicutes, Eubacterium siraeum et rel and Aneurinibacillus demonstrated similar metabolic activity. Conclusions: These findings indicate that after only two-weeks of a dietary exchange diet, the fecal metabolic profile is significantly altered and that these metabolic changes are closely associated with alterations in the structure and function of the gut microbial network.
