    Four children experienced saccharose-isomaltose malabsorption after artificial feeding. Diagnosis involved intestinal biopsies and enzyme tests, with limited success from hydrogen breath tests, necessitating a strict sucrose-free diet.

    Area of Science:

    • Pediatric Gastroenterology
    • Human Nutrition
    • Digestive Physiology

    Background:

    • Congenital sucrase-isomaltase deficiency (CSID) is a rare genetic disorder affecting carbohydrate digestion.
    • Symptoms often manifest in infancy or early childhood, typically after the introduction of sucrose-containing foods.
    • Accurate diagnosis is crucial for effective management and preventing long-term complications.

    Observation:

    • This study details four pediatric cases of saccharose-isomaltose malabsorption.
    • Clinical symptoms emerged subsequent to artificial feeding regimens.
    • Diagnosis was confirmed through small intestine biopsy and disaccharidase enzyme activity assays.

    Findings:

    • Histological examination revealed normal small intestinal morphology.

  • Lactase enzyme activity was within normal limits.
  • The sucrose hydrogen (H2) breath test yielded positive results in only one of the four cases.
  • Despite a sucrose-free diet, no improvement in tolerance was observed during the treatment period.

    • Implications:

    • Highlights the diagnostic challenges in saccharose-isomaltose malabsorption, particularly with standard breath testing.
    • Underscores the importance of integrating multiple diagnostic modalities, including histology and enzyme assays.
    • Suggests potential complexities in dietary management or underlying factors influencing treatment response in pediatric CSID.
