Cystic fibrosis (CF) meconium disease does not always mean pancreatic insufficiency in infants. Impaired pancreatic fluid secretion, not just enzyme deficiency, may cause intestinal obstruction in CF.

Area of Science:

  • Pediatric Gastroenterology
  • Cystic Fibrosis Research
  • Neonatal Intestinal Disorders

Background:

  • Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs, including the pancreas.
  • Meconium-related intestinal obstruction is a common early manifestation of CF.
  • The role of pancreatic exocrine function in meconium disease is not fully understood.

Observation:

  • Two infants with CF presenting with meconium ileus and meconium plug showed no initial signs of pancreatic insufficiency.
  • Pancreatic secretory function tests revealed reduced enzyme secretion in both infants.
  • One infant with meconium ileus had severely limited pancreatic fluid secretion, while the other with meconium plug had better fluid secretion but poorer proteolytic activity.

Findings:

  • Meconium disease in CF infants does not necessitate pancreatic insufficiency or enzyme replacement therapy in infancy.

  • Reduced pancreatic enzyme secretion may contribute to meconium disease even without overt pancreatic insufficiency.
  • Impaired pancreatic fluid secretion appears to be a significant factor in the pathogenesis of meconium ileus.

    • Implications:

    • Pancreatic exocrine function, particularly fluid secretion, plays a crucial role in preventing meconium-related intestinal obstruction in CF.
    • The interplay between intraluminal fluid and pancreatic enzyme activity may determine the risk and severity of intestinal obstruction in CF.
    • Further research into pancreatic fluid secretion mechanisms in CF is warranted for improved understanding and management of meconium disease.
