Polyamine compartmentalization in various human disease states.

K D Cooper, J B Shukla, O M Rennert

    Clinica Chimica Acta; International Journal of Clinical Chemistry
    |January 2, 1978
    PubMed
    Summary

    This study analyzed polyamine levels in blood cells, finding the spermine/spermidine ratio useful for identifying blood disorders. Different ratios indicated proliferative states versus red blood cell abnormalities.

    Area of Science:

    • Biochemistry
    • Hematology
    • Oncology

    Background:

    • Polyamines (putrescine, spermidine, spermine) are crucial for cell growth and function.
    • Altered polyamine levels are implicated in various diseases, including cancer and hematological disorders.
    • Erythrocyte absorption of polyamines may serve as a diagnostic indicator.

    Purpose of the Study:

    • To quantify polyamine concentrations in different blood cell fractions.
    • To investigate the utility of the spermine/spermidine ratio in differentiating disease states.
    • To explore the relationship between polyamine levels, erythrocyte absorption, and specific pathologies.

    Main Methods:

    • Whole blood separation into erythrocytes, mononuclear leukocytes, polymorphonuclear leukocytes, platelets, and plasma.

  • Quantification of putrescine, spermidine, and spermine concentrations in each fraction.
  • Analysis of patient cohorts including controls, psoriasis, hereditary elliptocytosis, chronic lymphocytic leukemia, lung cancer, non-Hodgkin's lymphoma, sickle cell anemia, and progeria.

    • Main Results:

    • Elevated blood polyamine levels were often associated with erythrocyte absorption.
    • The spermine/spermidine ratio effectively localized abnormalities and characterized polyamine alterations.
    • Proliferative conditions showed higher spermine/spermidine ratios compared to controls.
    • Erythropathies (hereditary elliptocytosis, sickle cell anemia) exhibited reversed spermine/spermidine ratios.

    Conclusions:

    • Blood polyamine analysis, particularly the spermine/spermidine ratio, is a valuable tool for diagnosing and characterizing hematological and proliferative diseases.
    • Erythrocyte polyamine absorption patterns can provide further insights into disease mechanisms.
    • This approach offers potential for non-invasive disease monitoring and differential diagnosis.
