Аннотация
BACKGROUND: Cutaneous leishmaniasis (CL) presents as 1 or more skin lesions, which makes local therapy inherently attractive compared to systemic therapy that exposes the whole body to a drug. For 30 years, 15% paromomycin topical formulations have been in clinical experimentation. Recently, 15% paromomycin in Aquaphilic, a complex base to facilitate adsorption into the lesion, was found superior to aquaphilic vehicle for Old World Leishmania major disease.
METHODS: We performed a randomized trial of 15% paromomycin in Aquaphilic (40 patients) vs Aquaphilic vehicle (20 patients) vs a positive control (intralesional pentamidine; 20 patients) against L. braziliensis CL in Bolivia.
RESULTS: Cure rates after 6 months of follow-up were 31 of 40 (77.5%, 95% confidence interval [CI] 62.5-88%) for paromomycin-Aquaphilic, 2 of 20 (10%, 95% CI 3-30%) for Aquaphilic vehicle (P < .0001 vs paromomycin-Aquaphilic), and 14 of 20 (70%, 95% CI 48-85.5%) for intralesional pentamidine. Both paromomycin-Aquaphilic and the Aquaphilic vehicle were very well tolerated, with only grade 1 adverse reactions in 5-10% of patients.
CONCLUSIONS: Against L. braziliensis CL, a prevalent, aggressive form of New World CL, 15% paromomycin-aquaphilic was vastly superior to a negative vehicle control and was comparable in efficacy to a positive control. This study enlarges the potential use of 15% paromomycin-Aquaphilic from one form of Old World CL to CL more generally.
