[Thrombopenia caused by pentosan polysulfate].

J Allal, D Herpin, B Schnebert

    Annales De Cardiologie Et D'Angeiologie
    |February 1, 1987

    Summary

    Pentosane polysulfate (PSP) can cause serious thrombopenias, leading to clots and bleeding. Monitoring platelet counts is crucial during PSP treatment due to potential immune-related adverse effects.

    Area of Science:

    • Pharmacology
    • Hematology
    • Immunology

    Background:

    • Pentosane polysulfate (PSP) is a medication with anticoagulant properties.
    • Thrombocytopenia, a condition characterized by low platelet counts, is a potential adverse effect of certain medications.
    • Understanding drug-induced immune reactions is critical for patient safety.

    Observation:

    • Two cases of thrombopenias associated with Pentosane Polysulfate (PSP) treatment are presented.
    • Thrombocytopenia onset occurred between 5-15 days of PSP treatment or rapidly after heparin exposure.
    • Clinical manifestations included hematomas, arterial/venous thromboses, and hemorrhages.

    Findings:

    • Pentosane Polysulfate (PSP) may directly cause or sensitize patients to thrombopenia.
    • Platelet aggregation tests were consistently positive in the presence of PSP.
    • An immunological mechanism is strongly suspected as the cause of PSP-induced thrombopenia.

    Implications:

    • Healthcare providers should be vigilant for thrombopenia in patients receiving Pentosane Polysulfate (PSP).
    • Regular monitoring of platelet counts is recommended during PSP therapy.
    • Early detection and management of PSP-induced thrombopenia can prevent severe clinical complications.
