Amphotericin-B, a broad spectrum antifungal agent, has been known to cause adverse effects such as nephrotoxicity and infusion-related side effects such as fever, chills, rigor, and arthralgias. However, ototoxicity as an adverse effect of Amphotericin-B has not yet been reported in medical literature. We here report a case of a reversible form of ototoxicity induced by liposomal Amphotericin-B...
The activity of fluconazole and amphotericin B against three isolates of Cryptococcus neoformans was evaluated, with fluconazole and amphotericin B MICs of 2.0-4.0 mg/L and 1.0 mg/L respectively, using time-kill curve methods. Fluconazole was fungistatic against all isolates tested (<99.9% decrease in cfu from initial inoculum). The fungistatic activity of fluconazole was not enhanced by increa...
Cilofungin, amphotericin B, and a combination of the two drugs were compared in a model of aspergillosis in immunocompetent mice in three experiments. Cilofungin was equivalent to amphotericin B in preventing death and eradicating cerebral aspergillosis, but it did not sterilize the kidneys. This is the first demonstration of the in vivo activity of cilofungin against any fungus other than Cand...
Four conformationally restricted analogues of pentamidine were prepared. Then, different concentrations (0.039, 0.078, 0.156, 0.312 and 0.625 mg/mL) of each compound and two positive controls (amphotericin B and pentamidine, 0.625 mg/mL), one negative control (culture medium) and one solvent control (DMSO) were prepared and placed in 24-well plates containing 50000 parasite per well. Promastigo...
OBJECTIVES The aim of the present investigation was to study and characterize the effect of voriconazole on the fungicidal activity of amphotericin B. METHODS Four strains of Candida albicans susceptible to voriconazole were exposed to voriconazole and amphotericin B, either alone, simultaneously or sequentially in an in vitro kinetic model. Bolus doses resulting in voriconazole and amphoteri...
Both intrinsic and acquired resistance to amphotericin B have been documented for Candida lusitaniae. Amphotericin B remains the drug of choice for many critical fungal infections, and the detection of resistance is essential to monitor treatment effectively. The limitations of the National Committee for Clinical Laboratory Standards (NCCLS) reference methodology for detection of amphotericin B...
Several studies have reported the occurrence of infections caused by Candida yeasts as well as the increasing prevalence of non albicans species. The aim of the present work is focused on the obtaining of heteroresistance to amphotericin B and fluconazole in Candida species using two distinct methodologies: selection and induction. Resistant samples were obtained by selective pressure using a m...
Drug Utilization Evaluation (DUE) studies facilitate assessing the appropriateness and rational use of medications.The goal of the present study was to evaluate Amphotericin B usage in neutropenic patients. A prospective DUE study was performed in Hematology-Oncology and Stem Cell Transplantation wards at Taleghani hospital for one-year. National comprehensive cancer network, clinical practice ...
The molecular action of polyene macrolides with antifungal activity, amphotericin B and natamycin, involves recognition of sterols in membranes. Physicochemical and functional studies have contributed details to understanding the interactions between amphotericin B and ergosterol and, to a lesser extent, with cholesterol. Fewer molecular details are available on interactions between natamycin w...
The purpose of this study was to analyze the usage of amphotericin B desoxycholate in a small community hospital, with special emphasis on its side effects and need for premedication. We performed a retrospective chart review for patients who received intravenous amphotericin B from January 1993 to May 1996. Temperature elevation, clinical symptoms during infusion, need for premedication, and f...
