Effectiveness of miltefosine-pentoxifylline compared to miltefosine in the treatment of cutaneous leishmaniasis in C57Bl/6 mice

Rev Soc Bras Med Trop. 2014 Jul;47(4):517-20. doi: 10.1590/0037-8682-0202-2013.

Abstract

Introduction: The treatment of leishmaniasis ischallenging, given the difficulties in drug administration and resistance. Therefore, we chose to test the efficacy of miltefosine combined with pentoxifylline.

Methods: Twenty-seven isogenic C57Bl/6 mice were infected with Leishmania (Leishmania) amazonensis, and equally divided into three groups: miltefosine (200mg/kg/day), miltefosine (200mg/kg/day) with pentoxifylline (8mg/kg/day), and untreated. Response to treatment was evaluated using paw diameter and parasitological criteria.

Results: The number of viable Leishmania reduced significantly within the miltefosine-pentoxifylline group (p < 0.05).

Conclusions: There is hope that a viable treatment exists for Leishmania infection.
