Post-transfusion purpura as a gynecologic complication
Obstetrics and Gynecology
|March 1, 1980
Summary
Post-transfusion purpura (PTP) is a severe bleeding disorder typically affecting multiparous women after blood transfusions. Prompt diagnosis and treatment with plasmapheresis or exchange transfusion are crucial for managing this potentially fatal condition.
Area of Science:
- Hematology
- Immunology
- Gynecology
Background:
- Post-transfusion purpura (PTP) is a distinct thrombocytopenic disorder.
- It primarily affects women, often multiparous, following blood transfusions.
Observation:
- PTP presents as acute, severe thrombocytopenia with hemorrhage, typically 5-8 days post-transfusion.
- Typical patients are middle-aged women with a history of transfusion and surgery, frequently gynecologic.
Findings:
- Diagnosis involves normal clotting, increased bone marrow megakaryocytes, and platelet-reactive antibodies.
- Platelet antibodies are detected via clot-retraction inhibition, complement fixation, or 51Cr-release assays.
Implications:
- Exchange transfusion or plasmapheresis are primary treatments for PTP.
- This case report highlights PTP's relevance in gynecologic contexts, addressing a gap in the literature.
