Pharmacodynamic and immunological interactions of amphotericin B formulations and voriconazole with human neutrophils against mature Scedosporium apiospermum and Fusarium spp. biofilms.

Background: Mould infections caused by Scedosporium apiospermum and Fusarium solani species complex (FSSC) biofilms are rising among immunocompromised and immunocompetent patients. Little is known about the immunomodulatory effects of antifungal agents against these moulds. We examined the effects of deoxycholate and liposomal amphotericin B (DAmB, LAmB) and voriconazole on antifungal activities and immune responses of neutrophils (PMNs) against mature biofilms compared with their planktonic counterparts.

Activity of Amphotericin B Formulations and Voriconazole, Alone or in Combination, against Biofilms of and Fusarium spp.

and Fusarium species are emerging opportunistic pathogens, causing invasive fungal diseases in humans, particularly in immunocompromised patients. Biofilm-related infections are associated with increased morbidity and mortality. Here, we assessed the ability of Scedosporium apiospermum and Fusarium solani species complex (FSSC) isolates to form biofilms and evaluated the efficacy of deoxycholate amphotericin B (D-AMB), liposomal amphotericin B (L-AMB), and voriconazole (VRC), alone or in combination, against mature biofilms.

Voriconazole Antifungal Prophylaxis in Children With Malignancies: A Nationwide Study.

Background: Antifungal prophylaxis (AFP) is recommended in at-risk hematology-oncology patients. We evaluated the safety of AFP with voriconazole (VRC) in pediatric hematology/oncology patients.

Materials And Methods: A retrospective study of VRC AFP in children with malignancies hospitalized in all 7 Greek pediatric hematology/oncology centers during 2008 to 2012 was conducted.

Diagnosis of invasive fungal diseases in pediatric patients.

The optimal management of invasive fungal infections (IFIs) in children requires prompt and precise diagnosis that enables timely implementation of appropriate antifungal therapy and decreased use of unnecessary toxic antifungals. Areas covered: Traditional approaches such as culture, microscopy and histopathology remain the gold standard but are often not sufficiently sensitive and specific. These limitations have led to the development of alternative non-invasive diagnostic methods that in most cases detect fungal components, such as antigens or nucleic acids.
