Purpose: This is a case study of Fusarium keratitis progressing to endophthatmitis that was successfully treated with a tiposomal formulation of amphotericin B (AmBisome] and local natamycin 5%.
Methods: A 41-year-old man presented with a clinical picture of endophthalmitis following deep Fusarium solani keratitis. Treatment with natamycin 5% drops and intravenous amphotericin B 150 mg per day caused renal failure and did not alleviate the endophthalmitis. Therefore, intravenous amphotericin B was replaced with intravenous AmBisome, 300 mg per day, to a cumulative dosage of 5.4 g.
Results: Both the endophthalmitis and keratitis were alleviated within several weeks after starting AmBisome treatment. No systemic toxicity was noted. The final ophthalmoLogic examination showed a paracentral corneal scar, and a satisfactory best corrected visual acuity of 20/40.
Conclusions: Due to their relatively low systemic toxicity, liposomal formulations of amphotericin B can be administered in higher doses than traditional unencapsulated ntravenous amphotericin B achieving higher concentrations in the target organ.

Amphotericin B eye drops (reconstituted from lyophilized Amphotericin B formulation indicated for intravenous use) is used off-label for fungal keratitis. However, the reconstituted formulation is stable only for a week, even after refrigeration. Moreover, a high dosing frequency makes it an inconvenient treatment practice.

The aim of this work is to investigate the effects of L-AMB (Amphociene) on liver and lung tissues in adult mice, and the role of vitamin D3 in reducing its side effects. Amphotericin B (AMB), a polyene macrolide antibiotic, is used to treat serious fungal infections and leishmaniasis. It may cause increased serum aminotransferase and hyperbilirubinemia due to interference with hepatic cytochrome P450.

Rationale: This article summarized the nursing experience of phlebitis caused by intravenous infusion of amphotericin B cholesterol sulfate complex in a patient with myelodysplastic syndrome.
Patient Concerns: A 59-year-old man with myelodysplastic syndrome complicated with fungal infection was treated with antifungal therapy.
Diagnoses: Patient with myelodysplastic syndrome was diagnosed with secondary phlebitis caused by liposomal amphotericin B.

Amphotericin B (AmB) causes toxicity to the erythrocyte membrane, leading to hemolysis, which limits the clinically effective dose for AmB intravenous therapy in invasive fungal infections. The molecular mechanism by which AmB adheres to the membrane of erythrocytes is the key factor in causing AmB to be toxic to the membrane of erythrocytes, but it is not yet fully understood; the mechanism by which AmB adheres to the liquid microdomains with higher fluidity formed by cholesterol and unsaturated phospholipids remains especially unclear. This study examined the adsorption of AmB at different concentrations, 5, 45, 85, and 125 μg/mL, on unsaturated phospholipid membranes containing 50 mol% cholesterol.

Rhino-orbital-cerebral mucormycosis (ROCM) is an opportunistic infection that has increased due to COVID-19 with the use of corticosteroids and diabetes being the most important predisposing factors. Orbital apex syndrome with central retinal artery occlusion secondary to mucormycosis is relatively rare. This case report highlights a case of a 62-year-old female with poorly controlled diabetes and a history of COVID-19 two weeks prior, who presented with acute right eye painful visual loss for three days associated with bulging of the right eye and drooping of the eyelid.
