BACKGROUND: Despite prophylactic platelet transfusions, bleeding remains a significant problem in thrombocytopenic patients.
METHODS: The antifibrinolytic agent epsilon aminocaproic acid (EACA) was administered to 44 chronically (median duration, 273 days) and severely (platelet count, 8 × 10(9)/L; range, 1 × 10(9)/L-19 × 10(9)/L) thrombocytopenic patients with hematological malignancies. Prophylactic EACA at a dose of 1 g twice daily was orally administered for a median duration of 47 days (range, 7 days-209 days) until the platelet count recovered to > 30; × 10(9) /L. Platelets were only transfused if bleeding occurred.
RESULTS: While receiving EACA, 59% of the patients did not bleed, 25% had 19 episodes of spontaneously resolving minor bleeding that did not require platelet transfusion, and 16% received a median of 4 platelet transfusions (range, 1 transfusion-8 transfusions) for 1 major traumatic and 9 spontaneous grade 2 to grade 3 bleeding (based on the World Health Organization classification of idiopathic thrombocytopenic purpura). No EACA toxicities were noted, and venous thromboses were not observed.
CONCLUSIONS: EACA is well tolerated and is associated with a low risk of major bleeding in patients with hematological malignancies who are experiencing chronic severe thrombocytopenia.
