PG - 332-5 AB - OBJECTIVE: To report 2 cases of nonconvulsive status epilepticus (NCSE) following infusion of ifosfamide. CASE SUMMARIES: Two patients who received ifosfamide-containing chemotherapy developed NCSE. One woman received ifosfamide 1000 mg/m2 (1 h infusion on days 1-5); confusion, lethargy, and speech deterioration developed on day 3. The second patient developed similar symptoms on day 3 of treatment with 2500 mg/m2. Both patients responded to intravenous administration of diazepam 10 mg and were given levetiracetam as maintenance therapy. DISCUSSION: The severity and presentation of central nervous system toxicity due to ifosfamide varies greatly and involves a spectrum ranging from subclinical electroencephalogram changes to coma. NCSE, an epileptic disorder in which typical convulsive activity is absent, has previously been reported in only 4 patients receiving ifosfamide. Levetiracetam may be used for maintenance antiepileptic therapy after diazepam administration. CONCLUSIONS: Among the many presentations of ifosfamide neurotoxicity, clinicians should consider NCSE as a possible explanation for changes in consciousness in a patient receiving this agent. An objective causality assessment by use of the Naranjo probability scale revealed that NCSE due to ifosfamide was probable.
