In Vitro and In Vivo Anti-parasitic Activity of Artemisinin Combined With Glucantime and Shark Cartilage Extract on Iranian Strain of Leishmania major (MRHO/IR/75/ER)

خلاصه انگلیسی

Background: The adverse effects and increased resistance of drugs necessities the discovery of novel combination therapy. Objectives: This study aimed to examine the effects of Artemisinin plus glucantime or shark cartilage extract on the Iranian strain of Leishmania major (MRHO/IR/75/ER) in vitro and in vivo. Methods: In in vitro experiments, the effects of drugs and their combination in different concentrations (3. 12-400 � g/mL) on the promastigotes, amastigotes, and un-infected macrophage cells were evaluated. In in vivo experiments, infected BALB/c mice were used as a cutaneous leishmaniasis model to evaluate the effects of the drugs and their combinations with different routes of administrations (namely Artemisinin: oral, ointment, and intraperitoneal; glucantime: intraperitoneal, intramuscular, intralesional, and subcutaneous; shark cartilage extract: oral) on parasite burden, lesion size, and immune system modulation. Results: The results revealed that Artemisinin and glucantime in combination with shark cartilage extract had greater effects on promastigotes than either Artemisinin or glucantime (P < 0. 05), and that the combinations also had high cytotoxic effects on promastigotes and uninfected macrophages (P = 0. 001). These combinations had more inhibitory effects on amastigotes and infected macrophages than promastigotes. The lesion sizes and parasite burden in the spleen decreased against the combinations of the drugs in different administrations. It was also noticed that the best combination administration route of Artemisinin and glucantime, as strong inducers of INF- and Th1 immune response, were ointment and intramuscular, respectively (P < 0. 05). Conclusions: The findings indicate that Artemisinin-glucantime or Artemisinin-Shark cartilage combinations are effective inhibitors of L. major. However, further clinical trials are recommended to evaluate the effects of these combinations in human subjects.
