Faecal elastase 1 concentration is a marker of duodenal enteropathy.

چکیده
BACKGROUND Measurement of faecal elastase (FE1) is used widely to screen for pancreatic exocrine insufficiency (PI). FE1 does not allow differentiation of primary from secondary PI. AIMS To investigate the relation between duodenal morphology and FE1 in children with secondary PI resulting from primary gastrointestinal diseases. METHODS A group of 51 children underwent small intestinal biopsy and FE1 measurement. Villus to crypt ratio (VCR) and inflammation within the lamina propria of duodenal mucosal biopsy specimens were scored and compared with FE1 values. RESULTS In 51 children from nine diagnostic categories, a highly significant correlation between FE1 and both duodenal morphology and inflammation was found. CONCLUSION Small bowel enteropathy is associated with low FE1 concentrations, indicative of secondary exocrine pancreatic insufficiency.

OBJECTIVE To assess the concentration of faecal elastase-1 (EL-1) in pediatric patients with cystic fibrosis with mutation DeltaF508. METHODS Cross-sectional study with samples collected consecutively from 51 patients aged 4 months to 17 years old (mean 9.11±4.74); 32 (62.8%) patients were male. Clinical-demographic data were collected, as well as data on the type of mutation. Exocrine pancre...

BACKGROUND This study sought to correlate faecal and urinary N-methylhistamine (NMH) concentrations with resting versus degranulated duodenal mast cell numbers in dogs with chronic enteropathies (CE), and investigate correlations between intestinal mast cell activation and clinical severity of disease as assessed by canine chronic enteropathy clinical activity index (CCECAI), and between urinar...

BACKGROUND Nutrient malabsorption frequently occurs in HIV infected children, but very few studies have investigated exocrine pancreatic digestive capacity in these cases. AIMS To investigate pancreatic function in HIV infected children and to determine whether faecal fat loss, a prominent feature of intestinal dysfunction, is associated with pancreatic dysfunction. PATIENTS Forty seven chi...
متن کاملExocrine pancreas disfunction in severely traumatised patients and early enteral nutrition.
BACKGROUND We investigated exocrine pancreatic insufficiency in severely traumatised patients with enteral nutrition using the fecal elastase-1 concentration. METHODS The fecal elastase-1 levels of critically ill patients after major trauma (n=18) were determined in a prospective study. Early enteral nutrition was started with a high molecular diet via a naso-duodenal tube, starting 24-36 hou...
