OBJECTIVES Amphotericin B poly-aggregates are a new formulation of amphotericin B, which can be obtained cheaply. In this study, we tested the efficacy of this new formulation for treating a disseminated infection by Candida glabrata in a murine model. METHODS Mice were rendered neutropenic by intraperitoneal cyclophosphamide and intravenous 5-fluorouracil administration and infected intraven...

BACKGROUND Cryptococcal meningitis accounts for more than 100,000 human immunodeficiency virus (HIV)-related deaths per year. We tested two treatment strategies that could be more sustainable in Africa than the standard of 2 weeks of amphotericin B plus flucytosine and more effective than the widely used fluconazole monotherapy. METHODS We randomly assigned HIV-infected adults with cryptococc...

BACKGROUND In a previous randomized trial of voriconazole versus amphotericin B deoxycholate for primary therapy of invasive aspergillosis, voriconazole demonstrated superior efficacy and better survival. In that trial, treatment with voriconazole or amphotericin B deoxycholate could be followed with other licensed antifungal therapies (OLAT). Here, we report the impact of OLAT on the outcome o...

The alkyl glycerol ether rac-1-O-dodecylglycerol inhibited the growth of members of two genera of yeasts, Candida and Cryptococcus, and was strongly synergistic with amphotericin B. At one-half its MIC, dodecylglycerol decreased the MIC of amphotericin B by as much as 80-fold. This high degree of synergism between dodecylglycerol and amphotericin B was demonstrated against a number of species o...

OBJECTIVES The purpose of this investigation is the study of toxicity, in vivo distribution and therapeutic activity against candidiasis of poly-aggregated amphotericin B, in two different formulations: not microencapsulated (P-AMB) or incorporated in albumin microspheres (MP-AMB). METHODS The therapeutic efficacy and toxicity of amphotericin B formulations was studied in an immunocompetent m...

The sensitivities of Leishmania mexicana amastigote and promastigote forms to amphotericin B were investigated in vitro and found to be strongly influenced by the culture media used. When differences in culture media were minimized, there was no significant difference in the 50% inhibitory concentration values between the two life cycle stages. Stable amphotericin B-resistant amastigote and pro...

BACKGROUND Amphotericin B is a widely used broad-spectrum antifungal agent, despite being associated with significant adverse events, including nephrotoxicity. METHODS The present prospective study collected data on outcomes for 418 adult patients treated consecutively with polyenes in hematology and oncology wards in 20 hospitals in Europe. RESULTS Patients initially received amphotericin ...

Liposomal amphotercin B was compared with conventional amphotericin B for empirical antifungal therapy in febrile neutropenic patients in a randomized, double-blind, multicentre trial. Using a composite end-point, the two drugs were equivalent in overall efficacy. However, the liposomal amphotericin B treatment group had fewer proven fungal infections, fewer infusion-related side effects and le...

OBJECTIVE To evaluate the effects of four types of in-line filters on filtration rate, amphotericin B concentration and particulate matter. METHODS Filtration rates of amphotericin B fluid through in-line filters under maximum gravity flow were examined. The concentrations of amphotericin B and the particulate matter in the non-filtered and filtered amphotericin B fluid at the flow rate of 50...
