In search of a biomarker for complicated course of febrile neutropenia (FN), plasma IL-18 was measured in 92 hematological patients after intensive chemotherapy at the beginning of FN (days 0-3). Complicated course was defined as blood culture positivity or septic shock. IL-18 varied according to background hematological malignancy and showed an inverse correlation with leukocyte count. IL-18 was not associated with complicated course of FN, defined as blood culture positivity or septic shock, in the whole study group, but an association was observed on d1 and d2 after the onset of FN in the subgroup of autologous stem cell transplant recipients with non-Hodgkin lymphoma.
