Treatment of Cutaneous Leishmaniasis with Intense Pulsed Light: Is it Effective?

Background: Cutaneous leishmaniasis (CL) is a common parasitic disorder that is endemic in many countries. There is no completely effective treatment for this condition, but pentavalent antimony compounds are regarded as the main treatment. Different laser types have been used for treatment of CL with variable success but to our best knowledge, there is no published paper regarding use of intense pulsed light (IPL) for treatment of CL.

Materials and methods: In this randomized, single-blind clinical trial study, we compared the efficacy of intralesional glucantime alone versus intralesional glucantime plus weekly IPL for treatment of 54 patients with confirmed cutaneous leishmaniasis for a maximum of eight weeks as a randomized, clinical trial.

Results: Although it was not statistically significant, combination treatment was more effective than intralesional glucantime alone (P > 0.05). However, the velocity of healing was significantly higher in the IPL plus intralesional glucantime alone versus glucantime alone. No side effect was observed in both groups.

Discussion: To better evaluate the efficacy of IPL, more studies with a higher number of patients and using various IPL filters are recommended.
