Sucrase-isomaltase deficiency. A follow-up report
Archives of Disease in Childhood
|August 1, 1978
Summary
Sucrase-isomaltase deficiency often persists into adolescence, causing persistent diarrhea with sucrose intake. Dietary sucrose restriction can alleviate gastrointestinal symptoms in affected individuals.
Area of Science:
- Pediatric Gastroenterology
- Human Metabolism
- Genetic Disorders
Background:
- Sucrase-isomaltase deficiency is a genetic disorder affecting carbohydrate digestion.
- Symptoms include diarrhea and malabsorption, particularly after consuming sucrose.
Purpose of the Study:
- To assess the long-term effects of sucrase-isomaltase deficiency in children.
- To evaluate the persistence of sucrose malabsorption into adolescence.
- To determine the impact of dietary sucrose on gastrointestinal symptoms.
Main Methods:
- Longitudinal assessment of nine children diagnosed with sucrase-isomaltase deficiency.
- Sucrose tolerance tests to evaluate sucrose absorption.
- Dietary assessment and symptom tracking.
Main Results:
- All nine children experienced persistent diarrhea linked to sucrose ingestion.
- Sucrose malabsorption was confirmed to continue into adolescence.
- Three older patients, unaware of their condition, reported symptom improvement upon restricting dietary sucrose.
Conclusions:
- Sucrase-isomaltase deficiency can lead to chronic gastrointestinal issues persisting into adolescence.
- Ongoing sucrose malabsorption necessitates dietary management.
- Awareness and adherence to sucrose restriction are crucial for managing symptoms.
