Zinc absorption in inflammatory bowel disease.

L S Valberg, P R Flanagan, A Kertesz

    Digestive Diseases and Sciences

    Summary

    Zinc absorption is reduced in inflammatory bowel disease (IBD) patients, particularly those who are undernourished. While low absorption correlates with undernutrition, it

    Area of Science:

    • Gastroenterology
    • Nutritional Science
    • Biochemistry

    Background:

    • Inflammatory bowel disease (IBD) can affect nutrient absorption.
    • Zinc status is crucial for overall health and immune function.
    • Understanding zinc absorption in IBD is important for patient management.

    Purpose of the Study:

    • To investigate zinc absorption in patients with varying IBD activity.
    • To determine the relationship between zinc absorption, disease activity, nutritional status, and zinc status.
    • To assess biochemical and clinical signs of zinc deficiency in IBD.

    Main Methods:

    • Measured zinc absorption using a 65Zn radioisotope stool-counting test.
    • Compared zinc absorption in 29 IBD patients with 30 healthy controls.
    • Assessed nutritional state, disease activity, plasma zinc, and leukocyte zinc levels.

    Main Results:

    • Mean zinc absorption was significantly lower in IBD patients (45%) compared to controls (54%).
    • Reduced zinc absorption correlated with undernutrition but not directly with IBD activity.
    • Plasma and leukocyte zinc levels did not significantly differ between IBD patients and controls.

    Conclusions:

    • Impaired zinc absorption in IBD is primarily linked to undernutrition.
    • Biochemical or clinical evidence of zinc deficiency was uncommon in the studied IBD population.
    • Further research may be needed to explore zinc metabolism nuances in IBD.
