ABSTRACT
OBJECTIVES: Allergic bronchopulmonary aspergillosis (ABPA) can accelerate lung function decline in patients with cystic fibrosis (CF). Antifungal medication can be used in addition to systemic corticosteroid treatment. PATIENTS AND METHODS: We evaluated Aspergillus-specific IgE and the use of therapeutic drug monitoring of triazoles in a retrospective analysis of 32 patients. RESULTS: There was a significant reduction in Aspergillus IgE with posaconazole but not with other triazoles (Pâ=â0.026). Aspergillus IgE levels were inversely correlated with the therapeutic drug level of posaconazole. CONCLUSIONS: These data suggest that posaconazole is better than comparator azoles at decreasing serological response to Aspergillus and that this response was better with therapeutic levels of posaconazole.
