Abstract
Current treatment modalities in cutaneous leishmaniasis have low efficacy and high toxicity as well as high rate of resistance to treatment. In this study, for the first time we decided to evaluate efficacy of intralesional Glucantime plus niosomal zinc sulphate in comparison with intralesional Glucantime plus cryotherapy in the treatment of acute cutaneous leishmaniasis. This is a case-control study on 64 patients with cutaneous leishmaniasis in Kerman-Iran. Patients were categorized in 2 groups A and B whom were treated with weekly intralesional meglumine antimonite plus twice daily niosomal topical zinc sulphate versus weekly intralesional Glucantime plus every other week cryotherapy, respectively. We assessed the efficacy of treatment modalities (as partial and complete response) and their adverse effects by measuring size of the lesions every 2 weeks up to maximum of 12 weeks and 3 months after the end of the treatment. Partial response rate was 16.6% and 12.9% in group A and B, respectively (P = 0.784). Complete response rate was 73.3% and 80.6% in group A and B, respectively (P = 0.784). Complete response rate was achieved in 4.73 ± 0.29 weeks and 4.69 ± 0.28 weeks in group A and B, respectively (P = 0.925). Partial response rate was achieved in 2.92 ± 0.23 weeks and 2.65 ± 0.18 weeks, respectively (P = 0.365). Combination of niosomal zinc sulphate with intralesional Glucantime has equal efficacy versus combination of cryotherapy plus intralesional Glucantime in the treatment of acute cutaneous leishmaniasis. So, it can be used in cases that have resistance to first-line treatments.
