BACKGROUND: Sugar absorption tests are an effective, noninvasive way to assess intestinal permeability. The role of intestinal barrier integrity in complications and outcome of short-bowel syndrome is not known. The purpose of the study was to evaluate whether such tests provide information on the status of intestinal mucosa of these patients.
METHODS: Six children with short-bowel syndrome--median age, 12 months, and median small bowel length at birth, 30 cm--had a sugar test with 3-o-methyl-D-glucose, D-xylose, D-rhamnose, and melibiose approximately 2 months after operation. The melibiose/L-rhamnose ratio was used as an index of permeability, and percentages of 3-o-methyl-D-glucose and D-xylose absorbed were used as indices of absorption. Parenteral nutrition requirement, bowel length, liver disease, recent sepsis, and bacterial overgrowth were recorded.
RESULTS: Three patients had increased permeability, and all of them had had a recent episode of sepsis and severe liver disease. All subjects had malabsorption of 3-o-methyl-D-glucose, and five of six had malabsorption of D-xylose and L-rhamnose. The absorption of 3-o-methyl-D-glucose correlated with bowel length (r2 = 0.78; P = 0.04), whereas the absorption of D-xylose correlated with parenteral requirement (r2 = 0.66; P = 0.04) at that time.
CONCLUSIONS: Increased permeability was observed in three of six patients with short-bowel syndrome associated with a recent episode of sepsis and severe liver disease. Other indices of malabsorption correlated significantly with different clinical features of the disease. A prospective larger scale study in a homogeneous population is indicated to assess at multiple points during the disease course whether the test can be helpful in the management of these patients.
