The purpose of this observational study is to examine the rate at which elevated body
temperature (fever) is relieved by an itraconazole injection administrated to patients
experiencing neutropenic fever . A neutropenic fever is an elevated body temperature that
occurs at a time when the patient's white blood cell count is low. White blood cells aid the
body's normal defenses against infection, so a fever during this period might make it
difficult for the patient to fight infections.
