Sucrose malabsorption and impaired mucosal integrity in enterally fed critically ill patients: a prospective cohort observational study.

Objective: Inadequate nutrition is common in critical illness due in part to gastric stasis. However, recent data suggest that altered small intestinal mucosal function may be a contributing factor. The aim of this study was to examine the effects of critical illness on sucrose absorption, permeability, and mucosal morphology.

Effect of age on fructose malabsorption in children presenting with gastrointestinal symptoms.

Objectives: Fructose malabsorption can produce symptoms such as chronic diarrhoea and abdominal pain. Here, we retrospectively review breath hydrogen test (BHT) results to determine whether age has an effect on the clinical application of the fructose BHT and compare this with the lactose BHT.

Patients And Methods: Patients were referred to a gastroenterology breath-testing clinic (2003-2008) to investigate carbohydrate malabsorption as a cause of gastrointestinal symptoms.
