  • Prophylactic administration of liposomal amphotericin B is superior to treatment in a murine model of invasive aspergillosis after hematopoietic cell transplantation JOURNAL OF INFECTIOUS DISEASES Bitmansour, A., Brown, J. M. 2002; 186 (1): 134-137

    Abstract:

    With use of a novel model of invasive Aspergillus fumigatus, the efficacy of prophylactic versus therapeutic administration of liposomal amphotericin B (L-AmB) was tested in C57BL/6 mice. After lethal irradiation and transplantation of whole bone marrow (d 0), animals were challenged with conidia either intravenously or via nasal instillation on d +3 and divided into 3 groups: group I received 5% dextrose in water throughout the study period; group II received L-AmB, 5 mg/kg, beginning on d +4; and group III received L-AmB, 5 mg/kg on d -4, d -2, d 0, and d +2, then daily starting d +4. Groups I and II did not survive intravenous challenge, whereas group III had a 40% survival rate. After nasal instillation of conidia, the survival was 25%, 35%, and 85% for mice in groups I, II, and III, respectively. These results demonstrate that prophylactic administration of L-AmB increased early survival against lethal challenge with A. fumigatus, compared with therapy instituted after infection.
