Purpose To describe a complication of retrobulbar amphotericin B injections in the treatment of invasive rhino-orbital asperigillosis. Observations 27 year-old renal transplant recipient presented with a two-week history of headache, binocular diplopia and proptosis of the left eye. Endonasal biopsy on hospital day 3 confirmed the diagnosis of rhino-orbital invasive Aspergillus fumigatus invo...

We have examined the effects of the sterol-binding polyene antibiotics on macrophage tumoricidal capability. Incubation for 2 hr of activated macrophages from bacillus Calmette-Guérin-infected mice with amphotericin B at 0.5--2 microgram/ml or amphotericin B methyl ester at 0.5--10 microgram/ml enhanced the capability of activated macrophages to kill 3T12 cells. These polyenes did not make norm...

Concomitant use of allogeneic donor granulocyte transfusions and amphotericin B in febrile neutropenic recipients may be limited by the increased incidence of respiratory distress. In vitro effects of amphotericin B and AmBisome were compared on polymorphonuclear leukocyte (PMN) aggregation from PMNs isolated from granulocyte-colony-stimulating factor (G-CSF)/dexamethasone-mobilized allogeneic ...

Hebeka, Elias K. (Rutgers, The State University, New Brunswick, N.J.), and Morris Solotorovsky. Development of resistance to polyene antibiotics in Candida albicans. J. Bacteriol. 89:1533-1539. 1965.-Strains of Candida albicans resistant to the polyenes candidin and amphotericin B, but not to nystatin, were developed by sub-culturing the organism in gradually increasing concentrations of the an...

An antagonistic effect of voriconazole on the fungicidal activity of sequential doses of amphotericin B has previously been demonstrated in Candida albicans strains susceptible to voriconazole. Because treatment failure and the need to switch to other antifungals are expected to occur more often in infections that are caused by resistant strains, it was of interest to study whether the antagoni...

Standard therapy of human visceral leishmaniasis with parenteral pentavalent antimonial agents is generally curative but has the disadvantages of a 28-day treatment course, occasional treatment failures, and toxicity. The antifungal and antileishmanial agent amphotericin B has been complexed with lipids to develop a less toxic formulation of amphotericin B. Because lipid particles are phagocyti...

BACKGROUND Candida guilliermondii has been recognized as an emerging pathogen showing a decreased susceptibility to fluconazole and considerably high echinocandin MICs. AIMS Evaluate the in vitro activity of anidulafungin in comparison to amphotericin B and fluconazole against different isolates of C. guilliermondii, and their efficacy in an immunosuppressed murine model of disseminated infec...

OBJECTIVE To evaluate the cost-effectiveness of caspofungin vs. liposomal amphotericin B in the treatment of suspected fungal infections in the UK. METHODS The cost-effectiveness of caspofungin vs. liposomal amphotericin B was evaluated using a decision-tree model. The decision tree was populated using both data and clinical definitions from published clinical studies. Model outcomes included...

S urgical treatment of coccidioidomycosis is recognized as a proved method of curative therapy. However, there is not universal agreement as to the specific method of management. The decision regarding management is made on personal experience and judgment and this varies with the individual surgeon. In general, the division on methodology hinges on an opinion regarding administration of amphot...

Polyene macrolides nystatin and amphotericin B are widely used in the treatment of fungal infections. In order to characterize factors affecting polyene activity, we have isolated Saccharomyces cerevisiae mutants showing selective resistance to nystatin and amphotericin B. Characterization of two of these mutants (nystatin-resistant mutant X1/16 and amphotericin B-resistant mutant X3/33) is pre...
