Posaconazole prophylaxis in experimental azole-resistant invasive pulmonary aspergillosis.
We investigated the efficacy of posaconazole prophylaxis in preventing invasive aspergillosis due to azole-resistant Aspergillus fumigatus isolates. Using a neutropenic murine model of pulmonary infection, posaconazole prophylaxis was evaluated using three isogenic clinical isolates, with posaconazole MICs of 0.063 mg/liter (wild type), 0.5 mg/liter (F219I mutation), and 16 mg/liter. A fourth i...
متن کاملPharmacokinetics and pharmacodynamics of posaconazole for invasive pulmonary aspergillosis: clinical implications for antifungal therapy.
BACKGROUND Posaconazole is a triazole with anti-Aspergillus activity. However, little is known about the utility of posaconazole as primary therapy for invasive pulmonary aspergillosis. METHODS An in vitro model of the human alveolus was used to study the impact of minimum inhibitory concentrations (MIC) on exposure-response relationships. The pharmacokinetic-pharmacodynamic relationships of ...
متن کاملProphylaxis and treatment of invasive aspergillosis with voriconazole, posaconazole and caspofungin - review of the literature
Major progress for the management of invasive aspergillosis has come from the introduction of new antifungals since the late 1990s. Although mortality of invasive aspergillosis remains as high as 30-50%. Backbone of management are prophylaxis, early diagnosis and early initiation of antifungals for reduction of invasive aspergillosis related mortality. Randomized trials have been undertaken for...
متن کاملSuccessful treatment of azole-resistant invasive aspergillosis in a bottlenose dolphin with high-dose posaconazole
Invasive aspergillosis due to azole-resistant Aspergillus fumigatus is difficult to manage. We describe a case of azole-resistant invasive aspergillosis in a female bottlenose dolphin, who failed to respond to voriconazole and posaconazole therapy. As intravenous therapy was precluded, high dose posaconazole was initiated aimed at achieving trough levels exceeding 3 mg/l. Posaconazole serum lev...
متن کاملComparative pharmacodynamics of posaconazole in neutropenic murine models of invasive pulmonary aspergillosis and mucormycosis.
We used two established neutropenic murine models of pulmonary aspergillosis and mucormycosis to explore the association between the posaconazole area under the concentration-time curve (AUC)-to-MIC ratio (AUC/MIC) and treatment outcome. Posaconazole serum pharmacokinetics were verified in infected mice to ensure that the studied doses reflected human exposures with the oral suspension, delayed...
