Acquired factor X deficiency and amyloidosis

J R Krause

    American Journal of Clinical Pathology
    |February 1, 1977
    PubMed
    Summary

    Acquired Factor X deficiency is rare, but a link with amyloidosis is suggested by new cases. Further research is needed to understand how amyloidosis affects Factor X levels.

    Area of Science:

    • Hematology
    • Internal Medicine
    • Pathology

    Background:

    • Acquired Factor X deficiency is an uncommon bleeding disorder.
    • A potential association between acquired Factor X deficiency and amyloidosis has been previously suggested.
    • Six cases linking these conditions have been reported in medical literature.

    Observation:

    • This paper presents two new cases of acquired Factor X deficiency occurring alongside amyloidosis.
    • The findings suggest the observed relationship may be more than a mere coincidence.
    • The exact mechanism linking amyloidosis and Factor X deficiency remains unclear.

    Findings:

    • Amyloidosis may influence Factor X levels through consumption, inactivation, or reduced synthesis.
    • In one patient, administration of Factor II, VII, IX, and X concentrate temporarily normalized Factor X levels.
    • This suggests a potential therapeutic approach for managing Factor X deficiency in such cases.

    Implications:

    • The study highlights the importance of investigating for amyloidosis in adult patients presenting with isolated Factor X deficiency.
    • Early detection of amyloidosis can lead to timely management and potentially improve patient outcomes.
    • Further investigation into the pathophysiology is warranted to elucidate the precise relationship between amyloidosis and Factor X deficiency.
