OBJECTIVE: To assess the efficacy of a novel formulation of the polyene antibiotic, amphotericin B (AMB), as therapy for cutaneous leishmaniasis in different mouse strains.
METHODS: (AMB), was formulated into water-soluble transport particles, termed nanodisks (ND). Balb/c and CH3 mice infected with Leishmania major on Day 0 were administered vehicle alone, empty ND or AMB-ND on Day 1 and day 7, via the tail vein. Mice were sacrificed 25 or 50 days post inoculation and tissue histology evaluated. Balb/c mice treated with vehicle or empty ND showed signs of severe infection while CH3 mice had less inflammation and fewer parasites. AMB-ND treatment (2 mg/kg) had a marked therapeutic effect on L. major infected Balb/c mice and a discernable therapeutic benefit on CH3 mice.
CONCLUSIONS: AMB-ND is efficacious in the treatment of cutaneous leishmaniasis in both susceptible and resistant mouse strains. It may be inferred that AMB-ND may be useful for prophylactic and/or treatment of early stage Leishmania spp. infection.
