Post-transfusion purpura (PTP) is a rare bleeding disorder. This study presents two cases, highlighting variable treatment responses and the critical need for effective interventions in severe thrombocytopenia.

Area of Science:

  • Hematology
  • Immunology
  • Transfusion Medicine

Background:

  • Post-transfusion purpura (PTP) is a rare but severe bleeding disorder characterized by platelet alloimmunization.
  • It typically manifests 5-10 days after blood transfusion in sensitized individuals, leading to profound thrombocytopenia and hemorrhage.
  • While often self-resolving, PTP can cause life-threatening bleeding, necessitating prompt and effective management.

Observation:

  • Two cases of PTP are presented in multiparous, PlA1-negative women who received their first blood transfusion.
  • Both patients experienced severe thrombocytopenia and purpura following transfusion.
  • Initial treatment with corticosteroids proved ineffective in both cases.

Findings:

  • One patient responded to intravenous immunoglobulin (IVIG) therapy.

  • Plasmapheresis was the definitive, life-saving treatment for the second patient.
  • These findings underscore the variable efficacy of different treatment modalities for PTP.

    • Implications:

    • The management of PTP requires a tailored approach, as no single treatment is universally effective.
    • Prompt recognition and aggressive treatment are crucial to prevent potentially fatal hemorrhage.
    • Further research into optimal PTP treatment strategies is warranted, especially for refractory cases.
