Relation between malaria serum gamma-globulin concentration and the D-xylose absorption test

Area of Science:

• Tropical Medicine
• Nutritional Science
• Clinical Diagnostics

Background:

• Malaria is a significant health issue in African populations.
• The D-xylose absorption test is a common diagnostic tool for malabsorption.
• The impact of malaria on D-xylose excretion requires further investigation.

Purpose of the Study:

• To evaluate D-xylose excretion in African subjects with malaria.
• To determine the influence of malarial parasitemia and pyrexia on D-xylose test results.
• To explore potential correlations between D-xylose excretion and serum gamma-globulin levels in malaria patients.

Main Methods:

• Oral administration of a 25g D-xylose load to 15 African subjects with malaria.
• Measurement of D-xylose excretion.
• Re-evaluation of 9 subjects after malaria treatment.
• Analysis of serum gamma-globulin concentrations.

Main Results:

• Malarial parasitemia and fever did not significantly alter D-xylose test outcomes.
• A significant inverse correlation was observed between D-xylose excretion and serum gamma-globulin in untreated subjects.
• This finding suggests a potential link between malaria, immune response, and nutrient absorption.

Conclusions:

• The D-xylose test appears reliable for assessing absorption in malaria patients.
• Elevated gamma-globulin levels in untreated malaria may indicate impaired D-xylose absorption.
• Further research is warranted to understand the nutritional significance of these findings in malaria.
