Abstract

OBJECTIVE:

To determine the efficacy and safety of imiquimod in combination with meglumine antimoniate in treating cutaneous leishmaniasis.

DESIGN:

Prospective, randomized, assessor-blind, parallel-design, placebo-controlled trial.

SETTING:

Two primary care health clinics.

PATIENTS:

One hundred nineteen patients (59 patients in the imiquimod group and 60 in the placebo group) were included in the study.

INTERVENTIONS:

Patients were randomly assigned to receive a combined 4-week course of imiquimod or placebo with meglumine antimoniate treatment (20 mg/kg of pentavalent antimony daily for 2 weeks) in an endemic area of Leishmania tropica.

MAIN OUTCOME MEASURES:

The primary end point was clinical cure, defined as more than 75% reduction in the size of lesions compared with baseline at week 8.

RESULTS:

At the end of the 4-week treatment period, clinical cure was similar in both groups (11 patients [18.6%] in the imiquimod-treated group vs 18 patients [30.0%] in the placebo group) (P = .15). Four weeks after the end of treatment, 26 patients (44.1%) and 29 patients (48.3%) in the imiquimod-treated and placebo groups, respectively, were cured (P = .64). Pruritus and burning sensation were reported by 3 patients treated with imiquimod and by no patients treated with placebo.

CONCLUSION:

This study showed no beneficial effect of combining a 4-week course of treatment with 5% imiquimod cream and a standard course of treatment with meglumine antimoniate in patients with cutaneous leishmaniasis in an endemic area of L tropica.
