The xylose absorption test in normal Sudanese subjects

Area of Science:

• Nutritional science
• Gastroenterology
• Human physiology

Background:

• The xylose absorption test is a common diagnostic tool for evaluating small intestine function.
• Understanding normal xylose absorption is crucial for identifying malabsorption disorders.
• Factors influencing xylose absorption in diverse populations require further investigation.

Purpose of the Study:

• To assess d-xylose absorption in a cohort of healthy Sudanese men.
• To determine the prevalence of subnormal d-xylose absorption in this population.
• To investigate the potential impact of socioeconomic status on d-xylose absorption.

Main Methods:

• A cohort of 50 healthy adult Sudanese men participated in the study.
• A 5-gram oral loading dose of d-xylose was administered.
• Urine samples were collected to measure d-xylose excretion and absorption.

Main Results:

• Eighteen percent (9 out of 50) of the participants exhibited d-xylose absorption below the established normal range.
• No statistically significant difference in d-xylose absorption was observed between individuals of low socioeconomic status (n=30) and middle socioeconomic status (n=20).

Conclusions:

• A notable proportion of healthy Sudanese men may present with values below the normal range for d-xylose absorption.
• Socioeconomic status does not appear to be a confounding factor for d-xylose absorption in this specific healthy population.
• Further research is warranted to explore potential underlying physiological or environmental factors affecting xylose absorption in this demographic.
