Relapsing post-transfusion purpura. A preventable disease.

J L Budd, S E Wiegers, J M O'Hara

    The American Journal of Medicine
    |February 1, 1985
    PubMed
    Summary

    Post-transfusion purpura (PTP) can recur even after 17 years. Recognizing PTP is crucial for preventing future episodes and managing this rare immune disorder.

    Area of Science:

    • Immunology
    • Hematology
    • Transfusion Medicine

    Background:

    • Post-transfusion purpura (PTP) is a rare but serious complication following blood product transfusion.
    • It is an isoimmune disorder characterized by a sudden onset of severe thrombocytopenia.

    Observation:

    • A 56-year-old woman experienced her third episode of PTP.
    • This recurrence occurred 17 years after her last known exposure to the implicated antigen.

    Findings:

    • The case highlights the potential for delayed and repeated sensitization to platelet antigens.
    • Clinical and immunological features of PTP were reviewed in the context of this prolonged interval.

    Implications:

    • Unrecognized or delayed diagnosis of PTP can lead to recurrent, life-threatening bleeding.
    • Specific preventive strategies are essential for patients with a history of PTP to avoid future alloimmunization.
