An international expert panel was convened to deliberate the management of azole-resistant aspergillosis. In culture-positive cases, in vitro susceptibility testing should always be performed if antifungal therapy is intended. Different patterns of resistance are seen, with multi-azole and pan-azole resistance more common than resistance to a single(More)
Pneumonia severity assessment systems such as the pneumonia severity index (PSI) and CURB-65 were designed to direct appropriate site of care based on 30-d mortality. Increasingly they are being used to guide empirical antibiotic therapy and also possibly to detect patients who will require admission to the intensive care unit (ICU). We retrospectively(More)
Isavuconazole is the first broad spectrum prodrug triazole with efficacy against invasive fungal diseases including aspergillosis and mucormycosis. Characteristics include linear dose-proportional pharmacokinetics, intravenous and oral formulations allowing therapeutic streamlining, once daily dosing, absence of nephrotoxic solubilizing agents and excellent(More)
BACKGROUND Invasive fungal diseases (IFDs) are associated with considerable health and economic costs. Surveillance of the more diagnostically challenging invasive fungal diseases, specifically of the sino-pulmonary system, is not feasible for many hospitals because case finding is a costly and labour intensive exercise. We developed text classifiers for(More)
Post-induction aplasia for acute myeloid leukemia/myelodysplastic syndrome is a high-risk period for invasive fungal diseases. The effectiveness of fluconazole, itraconazole solution, voriconazole and posaconazole prophylaxis used consecutively from December 1998 to January 2010 in patients with acute myeloid leukemia/myelodysplastic syndrome undergoing(More)
PURPOSE OF REVIEW Antimicrobial stewardship (AMS) has overwhelmingly focussed on antibiotics while antifungal agents have been largely neglected despite the few published audits of antifungal drug use demonstrating clear deficiencies in prescribing behaviour. In this review, we outline not only the elements of antifungal stewardship (AFS) in common with AMS(More)
To determine whether any of several quality improvement interventions with none specifically targeting methicillin-resistant Staphylococcus aureus (MRSA) were associated with a decline in endemic MRSA prevalence in an intensive care unit (ICU) where active screening and contact isolation precautions for known MRSA colonised patients are not practised.(More)
A man with acute lymphoblastic leukaemia developed disseminated Scedosporium prolificans infection following chemotherapy for disease relapse while on posaconazole prophylaxis. Scedosporium prolificans infection during posaconazole prophylaxis has not been reported previously. This report is timely as the uptake of posaconazole, the broadest spectrum azole(More)
PURPOSE OF REVIEW Therapeutic drug monitoring (TDM) may be an important adjunct to optimizing the use of posaconazole. RECENT FINDINGS Limited clinical studies suggest that an exposure-response relationship for posaconazole exists for the treatment of established invasive fungal diseases (IFDs), with emerging but less compelling data supporting its role(More)
