IDSA Practice Guidelines for Aspergillus • Early management • Prompt, aggressive diagnosis (BIII) • Therapy initiated on suspicion of diagnosis (BIII) • Antifungal therapy • Intravenous therapy initiated (BIII) • AmB deoxycholate at maximum doses (1-1.5 mg/kg/d) (BIII) • Lipid AmB: impaired renal function or intolerance (AII) • Itraconazole: oral therapy, sequential use (CIII) • Adjunctive therapy: Surgery, combinations, immunotherapy (CIII) • New therapies and diagnostic tools needed to improve prognosis Stevens DA et al, Clin Infect Dis 2000;30:696-709

Trial Design for Invasive Mycoses • Limitations in trials for invasive mycoses • Relative infrequency • Difficult diagnosis (surrogate markers, high resolution imaging) • Host factors (underlying conditions, disease presentation) • Trial issues (slow enrollment, expensive, difficult, use of approved comparators, definitions/endpoints) • Large, prospective randomized trials for invasive aspergillosis: 2 • Ellis, 1998 (87 pts): Liposomal AmB 1 vs 4 • Bowden, 1998 (103 pts): ABCD vs D-AmB Rex JH et al, CID 2001;33:95-106; Patterson TF, et al.

Invasive Mycoses: Present and Future • Epidemiology • Increasing number of patients at risk • Changing patterns of disease • Major cause of morbidity and mortality • Improved prognosis • Prompt diagnosis • Host factors • Antifungal therapy • Early, aggressive “induction” antifungal therapy • New approaches and new agents needed
