 Despite their high toxicity, antimonials and amphotericin B deoxycholate are commonly used for treating visceral leishmaniasis VL. Few studies showing conflictive data about their efficacy and adverse events in pediatric population are available. This study aimed to evaluate efficacy and safety of amphotericin B deoxycholate vs. that of N-methylglucamine antimoniate in treating pediatric VL in Brazil. This was a randomized, open-label, 2-arm and controlled pilot clinical trial. Treatment naïve children and adolescents with VL without signs of severe illness were treated with N-methylglucamine antimoniate or amphotericin B deoxycholate. All patients were diagnosed with positive direct examination andor positive PCR for Leishmania spp. performed in bone marrow samples. The primary efficacy end-point was VL cure determined after 180 days of completion of treatment. The analysis was performed using intention-to-treat ITT and per protocol PP analyses.
