Comparison of Intralesional Glucantime With and Without Fractional CO₂ Laser in Adults With Cutaneous Leishmaniasis

A Randomized Controlled Trial Comparing Healing Outcomes of Intralesional Glucantime With and Without Fractional CO₂ Laser in Adults With Cutaneous Leishmaniasis

Cutaneous leishmaniasis is a common parasitic skin disease causing chronic ulcerative lesions and scarring. Intralesional meglumine antimoniate (Glucantime) is a widely used treatment; however, healing may be prolonged and cosmetic outcomes may be suboptimal. Fractional CO₂ laser therapy may enhance drug penetration, accelerate healing, and improve cosmetic results. This randomized controlled trial aims to compare the healing outcomes of intralesional Glucantime alone versus intralesional Glucantime combined with fractional CO₂ laser therapy in adult patients with cutaneous leishmaniasis treated at CMH Peshawar. A total of 150 participants will be randomized in a 1:1 ratio and followed for assessment of clinical healing, lesion size reduction, cosmetic outcomes, and adverse events.
