Rationale for New Topical Anthroponotic Cutaneous Leishmaniasis (ACL) Treatment in Kabul (rtt-ACL)

August 6, 2025 updated by: Kurt-Wilhelm Stahl, Waisenmedizin e. V. Promoting Access to Essential Medicine

Phase 2 Study Electrothermocauterisation of Afghan Patients With Anthroponotic Cutaneous Leishmaniasis With and Without Pharmaceutical Chlorite Listed in the German Drug Codex (DAC N-055)

The aim of the randomized double blind trial with 134 patients presenting old world cutaneous leishmaniasis is:

  • to evaluate the clinical efficacy of electro-thermo-cauterisation (ETC) followed by moist wound treatment versus ETC followed by moist wound treatment plus 0.05 % pharmaceutical chlorite that has been used in three European countries (Germany, Austria and Switzerland) in wound care management for more than 20 years;
  • to judge whether early wound care management would present a viable improvement to the actual anti-parasitic treatments mostly neglecting the chronic wound problem and to evaluate its long-term effect on immunity through relapse control 6 months after wound healing.
