Leishmania mexicana infection causes localized skin lesions that can lead to tissue damage and permanent disfigurement if not resolved. Currently, recommended treatments include intravenous administration of Amphotericin B, which is undesirable due to the associated cost and patient burden related to receiving regular injections. In this study, we evaluated the effect of topical treatment with a nanoliposomal formulation of Amphotericin B that is penetrable to the skin (SinaAmphoLeish 0.4%) in mice infected with L. mexicana by using ulcerated (BALB/c) and non-ulcerated (129SVE) models. BALB/c mice received a 4 week treatment following ulcerated lesion development, while 129SVE mice received a 10 week treatment beginning at week 5 post-infection. Although mice from both models showed comparable susceptibility to L. mexicana infection after topical treatment with SinaAmphoLeish relative to controls, 129SVE mice displayed a transient decrease in lesion sizes which eventually became similar to control mice. On other hand this treatment resulted in no reduction in the lesion sizes in BALB/c mice. 129SVE treated mice exhibited greater IFN-γ, IL-4, and IL-10 cytokine levels and higher T-cell proliferation in re-stimulated draining lymph node cells. BALB/c mice showed no differences in cytokine responses between treated and control mice. These findings indicate that topical SinaAmphoLeish treatment is not likely to be effective in the treatment of cutaneous leishmaniasis caused by L. mexicana.
