CohortThe authors prospectively performed the study from June 2002 to January 2004 in a consecutive series of adult patients with hematological disorders who were at risk for developing IA at KCMH, Bangkok, Thailand. Eligible patients were 1) receiving chemotherapy with an expected duration of neutropenia of less than 500 cells/µL of at least 7 days or 2) undergoing allogeneic bone marrow or peripheral blood stem cell transplantation. Those patients, who were under- going autologous bone marrow transplantation or less than 16 years old, were excluded from the present study. All patients were hospitalized, and antifungal prophylaxis with itraconazole oral solution (200-400 mg/day) was given twice a day throughout the period of neutropenia. Broad-spectrum antibiotics were empirically initiated at the first febrile episode of neutropenic patient according to the guidelines of Infectious Diseases Society of America. Patients, who had persistent fever after 5-7 days of appropriate antibiotic treatment, received amphotericin B (amphotericin B deoxy-cholate: 0.8-1.2 mg/kg/day or liposomal amphotericin B: 3-5 mg/kg/day) until the resolution of fever and neutropenia. During hospitalization, blood samples were obtained once or twice weekly until death or discharge from the hospital.

Disease Introduction MechanismInvasive fungal infections (IFIs) particularly invasive aspergillosis (IA) have been one of the major causes of morbidity and mortality in patients with hematological disorders who receive chemotherapy or undergo hematopoietic stem cell transplantation (HSCT). Early diagnosis of IA may improve the clinical outcome, but it usually requires invasive procedures to obtain specimens for culture and histopathologic examination. Unfortunately, such procedures are often precluded by thrombocytopenia or by the critical condition of the patients.
