Abstract
We report here four patients with acute leukemia, who developed seizure or tremor following treatment with imipenem, a new broad-spectram antibiotic. All four patients had no renal dysfuction and recovered after discontinuation of the drug. Two patients who developed seizure had a past history of cerebral hemorrhage with symptoms of meningitis in one and the other had received frequent intrathecal injections of methotrexate. Seizure also occurred in another patient who was given multiple intrathecal injections of methotrexate. The remaining old patient developed tremor after the first administration of imipenem which did not progress to convulsion. Cerebral hemorrhage or meningitis is known to predispose patients for convulsion following imipenem treatment. In addition, the present study suggests that central nervous system damage related with intrathecal injections of methotrexate may be a predisposing factor. Thus, imipenem should be given with caution to acute leukemia patients who often have risk factors for developing imipenem-related complications.
