    The hydrogen breath test aids in diagnosing pediatric malabsorption, correlating with celiac disease severity and identifying Giardia in non-celiac cases. It also helps distinguish contaminated small intestine syndrome from absorptive surface reduction.

    Area of Science:

    • Pediatric Gastroenterology
    • Digestive Health
    • Diagnostic Testing

    Background:

    • Malabsorption in children presents diagnostic challenges.
    • Celiac disease and other conditions affect nutrient absorption.
    • Accurate diagnosis is crucial for appropriate management.

    Purpose of the Study:

    • To evaluate the utility of the hydrogen breath test (HBT) in pediatric malabsorption.
    • To correlate HBT findings with celiac disease severity and villous atrophy.
    • To identify causes of positive HBT in non-celiac children.

    Main Methods:

    • Jejunal biopsy and HBT performed on 57 children.
    • Participants included 34 with celiac disease and 23 with other malabsorption causes.
    • Analysis of HBT results in relation to villous damage and age.

    Main Results:

    • Positive HBT findings increased with villous damage in celiac disease.
    • Age dependence observed in subtotal villous atrophy, with more positive HBT in children under three.
    • Giardia lamblia infestation was the most common cause of positive HBT in the non-celiac group.
    • Lactose malabsorption confirmed by HBT in 27 cases, with only 11 experiencing diarrhea.
    • HBT differentiated contaminated small intestine syndrome from malabsorption due to reduced absorptive surface.

    Conclusions:

    • The hydrogen breath test is a valuable tool in diagnosing pediatric malabsorption.
    • HBT results correlate with the extent of villous atrophy in celiac disease.
    • HBT aids in identifying infectious causes like Giardia and distinguishing between different malabsorption etiologies.
