In vitro interaction of posaconazole with calcineurin inhibitors and sirolimus against zygomycetes.
OBJECTIVES Zygomycosis is an uncommon but devastating disease with few therapeutic options. Calcineurin inhibitors and sirolimus (mTOR inhibitor), commonly used in transplant patients as immunosuppressives, have antifungal activity. They are known to demonstrate synergy with triazoles against certain fungi, though limited data exist about their activity against zygomycetes. Our aim was to study...
متن کاملIn vitro and in vivo activities of posaconazole against zygomycetes with various degrees of susceptibility.
OBJECTIVES We analysed the in vitro and in vivo effects of posaconazole and amphotericin B against three clinical isolates of zygomycetes: Lichtheimia corymbifera, F1; and Rhizopus oryzae, F5 and F6. METHODS In vitro activities of both drugs were assessed by determining MICs, minimum fungicidal concentrations (MFCs) and fungal damage measured by the XTT assay against either the spores or the ...
متن کاملPosaconazole enhances the activity of amphotericin B against hyphae of zygomycetes in vitro.
The in vitro activity of posaconazole plus amphotericin B against conidia and hyphae of 30 clinical zygomycetes was investigated. The combination of posaconazole with amphotericin B was found to be significantly more synergistic (40%) against hyphae (P < 0.05) than against conidia (10%). Antagonism was not observed.
متن کاملIn vitro interactions between antifungals and immunosuppressive drugs against zygomycetes.
The in vitro interaction of antifungals with immunosuppressive drugs was evaluated against zygomycetes. The combination of amphotericin B with cyclosporine, rapamycin, or tacrolimus was synergistic for 90%, 70%, and 30% of the isolates, respectively. For posaconazole, itraconazole, and ravuconazole, synergy was more frequently observed with cyclosporine than with rapamycin or tacrolimus and ant...
متن کاملPotential antifungal effects of human platelets against zygomycetes in vitro.
Zygomycosis is increasingly recognized in immunocompromised hosts. We investigated whether platelets become activated after contact with Zygomycetes and adhere to conidial and hyphal structures using immunofluorescence. The platelets' influence on fungal viability was evaluated by assessing hyphal elongation and hyphal damage. Platelets became activated and strongly adhered to conidia and hypha...
