The ocular toxicity of liposome-intercalated amphotericin B and commercial amphotericin B were compared after intravitreal injection in healthy pigmented rabbits. Ophthalmoscopic observations over 5 weeks following a single intravitreal injection showed vitreal band formation and focal retinal damage after doses of commercial amphotericin B as low as 5 micrograms. Such lesions were not seen in ...

Liposomal amphotericin B is a "true" liposomal formulation of amphotericin B with greatly reduced nephrotoxicity and minimal infusion-related toxicity. This broad spectrum polyene is well tolerated and effective against most invasive fungal infections. In view of the current limitations on diagnostic capability of invasive fungal infections, most clinicians are often compelled to use antifungal...

We report the penetration of liposomal amphotericin B into the pleural fluid of a patient with pulmonary zygomycosis and empyema. The ratio of area under the concentration-versus-time curve in pleural fluid (AUC(pleural fluid)) to that in serum (AUC(serum)) for liposomal amphotericin B over 24 h was 9.4%, with pleural fluid concentrations of 2.12 to 4.91 microg/ml. Given the relatively low leve...

ence in the LX 20 phosphorus assay. The occurrence of severe hyperphosphatemia during treatment with high-dose liposomal amphotericin was reported in a pediatric patient (3 ), but the possibility of pseudohyperphosphatemia caused by interference of liposomal amphotericin B in the phosphorus assay was not addressed. In this pediatric case, the phosphorus assay was performed on a Synchron LX20 an...

The Covid 19 infection which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) found to be associated with a wide range of bacterial and fungal co-infections. We report the first post COVID-19 Sino-orbital Mucormycosis in patient diabetes mellitus Sri Lanka. A 57 years old female history long standing uncontrolled presented left facial pain swelling. She has had positive...

We investigated the in vitro activity of nystatin and liposomal nystatin against 103 Candida isolates to determine the effect of both time and medium on MICs. We also compared the nystatin MICs with those of amphotericin B and fluconazole. Testing was performed in accordance with the National Committee for Clinical Laboratory Standards M27-A microdilution methodology with RPMI 1640, RPMI 1640 s...

Given the clinical success of commercial amphotericin B lipid products, investigators have begun making generic formulations of liposomal amphotericin B. Generic medicines are an attractive approach to help decrease the cost and accessibility to healthcare, provided that appropriate studies are performed to ensure bioequivalence with the parent product. This is of particular concern for liposom...

A patient with Candida spondylitis failed two weeks of fluconazole combined with caspofungin, and the infection relapsed despite six weeks of liposomal amphotericin B followed by two months of fluconazole. Six months therapy with high dose liposomal amphotericin B combined with flucytosine effectively cured the patient.

We present a case of a child with Leishmania infantum cutaneous leishmaniasis unresponsive to 2 courses of intravenous liposomal amphotericin B, a treatment failure that has not been reported in this Leishmania species. The patient responded to topical imiquimod and had no relapse. We review the literature on the treatment failure of liposomal amphotericin B for cutaneous leishmaniasis.
