Abstract
BACKGROUND: The aim of this study was to ascertain if prospective determination of specific gut hormones and growth factors could predict bowel adaptation in children with short bowel syndrome (SBS). METHODS: We studied independence from parenteral nutrition (PN) as the short-term result and discontinuation of enteral nutrition (EN) as the long-term result from a retrospective chart review of seven patients with SBS, who were managed in the absence of growth retardation. The correlation between increased number of enteral feeds or enteral nutrients and fasting serum gastrin, glucagon-like peptide 2 (GLP-2), citrulline, and D-amino acid oxidase (DAO) activity was analyzed. Five patients were weaned from PN, and two from EN. RESULTS: Fasting serum gastrin was significantly higher and serum GLP-2 lower in the PN-dependent patients than in the patients weaned from EN. The upper limit of fasting serum gastrin for PN independence and for EN independence was 300 and 200 pg/mL, respectively. The lower limit of fasting serum citrulline for PN independence was 15 μmol/L. The relationship between serum citrulline and DAO and the course of bowel adaptation, however, was poor. CONCLUSIONS: Serum citrulline is a predictor of PN independence in children with SBS. Fasting serum gastrin and GLP-2 are indicators for adaptation of the residual intestine, but this was a small study and further larger prospective trials are required to confirm these results.
