CohortA well-described persistently neutropenic rabbit model of IPA was used for the experiments. The three experimental arms consisted of uninfected control animals (n 13), animals infected endotracheally with A. fumigatus and untreated (n 17), and infected rabbits treated intravenously with one of the following antifungal agents (n 16): liposomal amphotericin B (LAMB) at 5 mg/kg of body weight, deoxycholate amphotericin B (DAMB) at 1 mg/kg, or ravuconazole (RVZ) at 5 mg/kg. Neutropenia was deliberately chosen for comparison of host biomarkers’ responses during the antifungal therapy to simulate a prominent condition for human infection.

Disease Introduction MechanismInvasive pulmonary aspergillosis (IPA) caused by Aspergillus fumigates is a devastating disease for immunocompromised patients. Successful management of patients depends on early diagnosis, effective therapy, and monitoring of therapeutic response. Detecting IPA and monitoring the response to therapy still remain very difficult, especially in the early stages of the disease. Currently, according to the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG), diagnosis of IPA relies on a positive computed tomography (CT) scan, culture and/or microscopic evidence of disease, and detection of A. fumigates antigens in a susceptible host.
