Advancement in drug therapies may provide new treatment for Cutaneous leishmaniasisNovember 21, 2018
Cutaneous leishmaniasis (CL) is a parasitic infection caused by Leishmania parasite. CL cases have increased dramatically in Syria and neighboring countries due to conflict-related displacement of Syrians. A study published in PLOS Neglected Tropical Diseases by Rana El Hajj at the American University of Beirut, Lebanon describes the development of a novel immunomodulatory analog that may be an effective treatment of CL.
Currently used therapies against CL may lead to partial or complete cure. However, they associate with many limitations, including repetitive painful injections, lack of availability, expensive cost, and emergence of resistant strains. Furthermore, their efficacy remains hindered by the patient's age and immune system. Researchers investigated the pre-clinical efficacy of an immunomodulatory drug, Imiquimod and one of its analogs, EAPB0503 on two strains (Leishmania major and Leishmania tropica) causing CL in the Middle East Area. They also tested these drugs on freshly isolated parasites from patients' biopsies and proved their leishmanicidal potency.
According to the authors, "Our findings establish Imiquimod as a strong candidate for treating L. tropica and show the higher potency of its analog EAPB0503 against CL". Their research is a promising advancement for the development of effective therapies for CL.
