Use of systemic antifungals in daily clinical practice in the haematology and oncology setting: results of a prospective observational analysis.

PURPOSE: To assess the role of systemic antifungal drugs as well as the frequency of potential drug interactions and adverse drug events of commonly used antifungals in an unselected haematology/oncology patient cohort. METHODS: A prospective analysis was performed in our haematology/oncology department between October 2006 and September 2009. Data were obtained from 250 consecutive patients who received treatment and/or prophylaxis with fluconazole (n = 191), liposomal amphotericin B (n = 105), voriconazole (n = 62), caspofungin (n = 27) and/or posaconazole (n = 22). We performed detailed reviews of patient charts and laboratory values in close cooperation with treating physicians and nursing staff and participated regularly in ward and chart rounds. Potential drug interactions were assessed using the electronic database Micromedex® 1.0 (Healthcare Series). RESULTS: In terms of adverse drug events, caspofungin (56%) and voriconazole (58%) revealed a slightly more favourable safety profile than liposomal amphotericin B (66%) and posaconazole (64%). We confirmed frequent nephrotoxic effects with the use of liposomal amphotericin B (20%). Regarding potential drug interactions, 97 (66%) of 147 evaluated patients were exposed to at least 1 of 22 different potentially interacting drug combinations involving systemic antifungal agents. Cyclosporine was the most prevalent potentially interacting drug in our cohort. CONCLUSIONS: Systemic antifungal drugs are widely used in the haematology/oncology setting and exhibit numerous potential drug interactions and adverse events in cancer patients. Our results highlight the challenges related to antifungal drugs and should valuably contribute to a safe and efficient application of this increasingly important class of drugs.

Challenging the current approaches to multiple myeloma- and other cancer-related bone diseases: from bisphosphonates to targeted therapy.

An international myeloma meeting entitled "Challenging the current approaches to multiple myeloma- and other cancer-related bone diseases: from bisphosphonates to targeted therapy" was held in Freiburg, Germany in July 2011 to discuss novel insights into and approaches to myeloma bone disease and other bone-seeking tumors. This review briefly summarizes the most prominent data of the meeting and current literature on our understanding of bone disease, the role of imaging techniques, operative interventions and systemic bone-seeking treatment, all of which should further improve our future therapeutic choices.
