Effectiveness and Safety of Amphotericin B Deoxycholate, Amphotericin B Colloidal Dispersion, and Liposomal Amphotericin B as Third-Line Treatments for Cutaneous and Mucocutaneous Leishmaniasis: A Retrospective Study

Abstract

Cutaneous leishmaniasis (CL) and mucocutaneous leishmaniasis (MCL) are endemic diseases in America, especially in some countries such as Colombia. Among the therapeutic options is amphotericin B (AB). Nevertheless, its lipid-associated formulations have better safety profiles and effectiveness in other diseases, so far with no comparative studies in CL or MCL. We conducted a retrospective descriptive study describing the effectiveness and adverse effects of AB deoxycholate (ABD), AB colloidal dispersion (ABCD), and liposomal AB (LAB) as third-line treatments for CL and MCL. The effectiveness of LAB (88.5%) was greater than those of ABCD (66.6%) and ABD (80.8%). There were also fewer adverse effects in the LAB group (46.2%) than in the ABD (96.1%) and ABCD (80.9%) groups. LAB is an alternative for the treatment of CL and MCL in patients with therapeutic failure to first- and second-line drugs; findings suggest it might be less toxic and more effective than ABD and ABCD.
