Summary

Fecal elastase-1 (E1F) is a useful non-invasive tool for diagnosing pancreatic insufficiency in children. However, low E1F levels can also occur in other digestive conditions like celiac disease.

Area of Science:

  • Pediatric Gastroenterology
  • Digestive Disease Diagnostics
  • Biomarker Analysis

Background:

  • Pancreatic insufficiency diagnosis in children can be challenging.
  • Non-invasive markers are needed for accurate pediatric diagnosis.

Purpose of the Study:

  • To evaluate fecal elastase-1 (E1F) and chymotrypsin (ChT) for diagnosing pancreatic insufficiency in pediatric patients.
  • To compare E1F and ChT performance across different pediatric digestive disease groups.

Main Methods:

  • Stool samples from 198 children were analyzed.
  • Children were categorized into three groups: healthy, pancreatic disease, and non-pancreatic digestive disease.
  • Fecal elastase-1 (E1F) and chymotrypsin (ChT) levels were measured.

Main Results:

  • Fecal elastase-1 (E1F) was significantly low in children with pancreatic diseases.
  • Normal chymotrypsin (ChT) levels were observed in some children with pancreatic insufficiency, especially those on enzyme therapy.
  • Decreased E1F levels were noted in a subset of children with non-pancreatic digestive diseases, including acute gastroenteritis and celiac disease.

Conclusions:

  • Fecal elastase-1 (E1F) is a valuable, non-invasive diagnostic tool for pancreatic insufficiency in children presenting with growth failure, chronic diarrhea, or cystic fibrosis.
  • Low E1F values should be interpreted cautiously, as they can also be present in conditions characterized by villous atrophy or very liquid stools.
