Abstract:
The persistence of abnormal coagulation test results after standard treatment with fresh frozen plasma (FFP) poses significant problems in children with acute leukemia requiring a diagnostic lumbar puncture and intrathecal chemotherapy. We report the prophylactic use of a single dose of 90 microg/kg recombinant activated factor VII (rFVIIa) in three children and the rapid correction of abnormal coagulation test results previously not corrected by FFP. Administration of rFVIIa was useful in avoiding a delay of diagnostic lumbar punctures and intrathecal chemotherapy. Hemorrhagic complications and adverse effects of rFVIIa were not observed. Prospective evaluation of this indication and dose appears warranted. (c) 2005 Wiley-Liss, Inc.
