1. The disease

Congenital diarrhea and enteropathies (CODEs) are monogenic disorders causing early onset of intractable diarrhea. Their diagnosis and management are challenging so that is why we decide to detect them really soon.

2. The symptoms

  • Congenital diarrhea and enteropathies (CODEs) are a group of diverse disorders characterized by chronic diarrhea, malabsorption and failure to thrive in infants. Diarrhea appears between 3 – 38 days of life. Lack of early signs or symptoms does not exclude the diagnosis.

3. Actions to take in case of early diagnosis

  • Infants with a positive genetic test (having 2 pathogenic variants or 2 copies of a single pathogenic variant in one of the 4 genes) should continue breastfeeding. Early treatment, with adequate diet and electrolytes replacement can save lives.
  • CODE is a life-threatening condition that requires lifetime management and regular follow-up with a paediatric gastroenterologist physician, dietician, and a multidisciplinary approach to care.
  • Elemental formula can be needed, when not tolerated, total parenteral nutrition is crucial.
  • Early and precise diagnosis is clue for adequate treatment.
  • Close electrolytes follow-up and fluids infusion is indicated.
  • Genetic counselling is highly recommended for family planning and evaluation of at-risk family members such as siblings.
