Abstract

Background: One of the main obstacles to malaria control in the world has been the emergence of resistance in Plasmodium falciparum to chloroquine and other anti-malarial drugs. This study aimed to review studies in Iran on resistance in P. falcipa-rum and P. vivax to drugs, and to reveal the mechanisms and molecular markers of resistance of these two species. Methods: The databases of PubMed, Scopus, Google Scholar, Magiran, and repu-table Iranian journals were searched to find published studies on the resistance in P. falciparum and P. vivax to antimalarial drugs in Iran. Results: There is a significant relationship between resistance to chloroquine in P. falciparum and the emergence of K76T mutation in the P. falciparum chloroquine-resistance transporter gene in Iran. Resistance to sulfadoxine-pyrimethamine (SP) in P. falciparum is also significantly associated with the development of mutations in the dihydrofolate reductase and dihydropteroate synthase genes. Resistance to chlo-roquine in P. vivax has not been reported in Iran and it is used as a first-line treat-ment for P. vivax malaria. Conclusion: P. falciparum has become resistant to chloroquine in different regions of Iran and is not currently used to treat malaria. Besides, cases have emerged of P. falciparum resistance to SP in different parts of southern Iran, and SP is not adminis-tered alone for treating P. falciparum. © 2021 Heidari et al.
