Monocytes in inflammatory bowel disease: absolute monocyte counts

A S Mee, J Berney, D P Jewell

    Journal of Clinical Pathology
    |October 1, 1980
    PubMed
    Summary

    Peripheral blood monocytosis is significantly elevated in ulcerative colitis, correlating with disease activity. Crohn's disease patients showed a trend towards higher monocyte counts, but without statistical significance or correlation to disease markers.

    Area of Science:

    • Immunology
    • Gastroenterology
    • Hematology

    Background:

    • Inflammatory bowel disease (IBD) encompasses ulcerative colitis and Crohn's disease, characterized by chronic gastrointestinal inflammation.
    • Monocytes play a crucial role in immune responses and inflammation, making them potential biomarkers in IBD.

    Purpose of the Study:

    • To precisely identify and enumerate peripheral blood monocytes in IBD patients.
    • To compare monocyte counts between ulcerative colitis, Crohn's disease, and control groups.
    • To assess the correlation between monocyte counts and disease activity in IBD.

    Main Methods:

    • A cytochemical staining technique was employed for accurate monocyte identification and enumeration.
    • Peripheral blood samples were analyzed from patients with ulcerative colitis, Crohn's disease, and healthy/disease controls.

    Main Results:

    • Significant monocytosis was observed in ulcerative colitis patients, strongly correlating with total white cell count and disease activity.
    • Peripheral blood monocyte counts were elevated in Crohn's disease patients compared to controls, but this finding lacked statistical significance.
    • No significant correlation was found between monocyte counts and white cell count or disease activity in Crohn's disease patients.

    Conclusions:

    • Peripheral blood monocyte counts can serve as a potential indicator of disease activity in ulcerative colitis.
    • Further research is needed to elucidate the role of monocytes in Crohn's disease pathogenesis and their potential as biomarkers.
