OBJECTIVE The aim of this investigation was to measure the postantifungal effect (PAFE) of 6 different oral Candida species following exposure to amphotericin B. MATERIALS AND METHODS Five oral isolates each of Candida albicans, Candida tropicalis, Candida krusei, Candida parapsilosis, Candida glabrata and Candida guilliermondii (total of 30 isolates) were examined for the presence of PAFE af...
BACKGROUND & OBJECTIVES Current therapy for leishmaniasis is limited and unsatisfactory. Amphotericin B, a second-line treatment is gradually replacing antimonials, the first-line treatment and is used as the preferred treatments in some regions. Though, presently it is the only drug with highest cure rate, its use is severely restricted by its acute toxicity. In the present study novel lipid-a...
Most patients with alveolar echinococcosis are diagnosed at a late stage when the disease has advanced to unresectable hepatic lesions. These patients require lifelong therapy with benzimidazoles, the only medical treatment currently available. To date, no treatment option remains for patients with benzimidazole intolerance or treatment failure. Amphotericin B was recently shown to exert antipa...
OBJECTIVES Mucormycetes (formerly known as zygomycetes of the order Mucorales) and hyaline moulds such as those of the genus Fusarium or Paecilomyces are emerging as significant human pathogens. The aim of the study was to determine the in vitro antifungal susceptibility of these fungi to older and newer antifungals and to investigate the antifungal activity of amphotericin B, posaconazole and ...
In order to provide tools for investigations of amphotericin B ion channels, new conjugates bearing a calix[4]arene scaffold covalently linked to four amphotericin B molecules were synthesized. These macromolecules adopt a cone conformation that mimics the structure of a transmembrane pore. The antifungal activity of the conjugates 3 and 4 was superior or similar to that of native amphotericin ...
Rhinocerebral mucormycosis (zygomycosis) primarily affects diabetic or immunosuppressed patients and typically progresses rapidly, necessitating surgical excision and antifungal therapy with amphotericin B. Large doses of amphotericin B are required for cure, causing significant renal toxicity. Amphotericin B colloidal dispersion (ABCD; Amphocil, Sequus Pharmaceuticals, Menlo Park, CA) is a 1:1...
We investigated the interaction between amphotericin B and azithromycin in vitro against 26 clinical isolates of Fusarium. Synergy was demonstrated in all isolates. Amphotericin B MICs were reduced from a mean of 1 mg/L when tested alone to a mean of 0.37 mg/L when tested in combination with azithromycin. Azithromycin demonstrated no activity against Fusarium when tested alone (MIC > 128 mg/L)....
KY-62 is a water-soluble analog of amphotericin B. In vitro testing of five clinical isolates of Candida albicans showed KY-62 to have potency similar to that of amphotericin B. KY-62 was administered to mice infected intravenously with C. albicans. In vivo, KY-62 was effective in immunocompetent mice, with potency similar to that of amphotericin B. KY-62 was well tolerated up to 30 mg/kg of bo...
