Liposomal formulation of amphotericin B for the treatment of mucosal leishmaniasis in HIV-negative patients

Background: Studies assessing the efficacy of liposomal amphotericin B (LAB) in the treatment of patients with mucosal leishmaniasis (ML) are very scarce in the literature and an optimal dose regimen has not yet been defined. Methods: We performed a retrospective and descriptive analysis from records of 16 patients with ML treated with LAB. The mean daily dose of LAB was 2.5 mg/kg/day. Results: Healing of the lesion was observed in 14 (88%) of the 16 patients. The mean cumulative doses, excluding the two treatment failures, were 2265 mg and 33 mg/kg. Conclusion: Liposomal amphotericin B in the cumulative dose of 30 to 35 mg/kg was able to achieve 100% effectiveness.
