Are pvcrt-o and pvmdr1 Gene Mutations Associated with Plasmodium vivax Chloroquine-Resistant Parasites? Biomedicines 2024; 12:141. [PMID: 38255246 PMCID: PMC10812985 DOI: 10.3390/biomedicines12010141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/19/2023] [Accepted: 12/29/2023] [Indexed: 01/24/2024] Open
Abstract
(1) Background: Malaria remains a significant global public health issue. Since parasites quickly became resistant to most of the available antimalarial drugs, treatment effectiveness must be constantly monitored. In Brazil, up to 10% of cases of vivax malaria resistant to chloroquine (CQ) have been registered. Unlike P. falciparum, there are no definitive molecular markers for the chemoresistance of P. vivax to CQ. This work aimed to investigate whether polymorphisms in the pvcrt-o and pvmdr1 genes could be used as markers for assessing its resistance to CQ. (2) Methods: A total of 130 samples from P. vivax malaria cases with no clinical and/or parasitological evidence of CQ resistance were studied through polymerase chain reaction for gene amplification followed by target DNA sequencing. (3) Results: In the pvcrt-o exons, the K10 insert was present in 14% of the isolates. Regarding pvmdr1, T958M and F1076L haplotypes showed frequencies of 95% and 3%, respectively, while the SNP Y976F was not detected. (4) Conclusions: Since K10-pvcrt-o and F1076L/T958M-pvmdr1 polymorphisms were detected in samples from patients who responded well to CQ treatment, it can be concluded that mutations in these genes do not seem to have a potential for association with the phenotype of CQ resistance.

Abstract
PURPOSE The study was aimed at detecting the mutation patterns in the drug targets in Plasmodium vivax that confer resistance to the common antimalarial agents used in India. METHODS A total of 27 Plasmodium vivax isolates collected from whole blood samples over a three year period were subjected to PCR amplification followed by sequencing of the genes pvmdr1, pvdhfr, pvdhps and pvk12, which serve as the molecular targets to detect resistance to chloroquine, pyrimethamine, sulfadoxine and artemisinin respectively. RESULTS The study found T958 M F1076L double mutants of pvmdr1 in 52 %(14/27) isolates, S58R S117 N double mutants of pvdhfr in 67 % (18/27) isolates, A383G A553G double mutant pvdhps in 59 % (16/27) isolates and wild type of pvk12 gene in all the isolates. CONCLUSIONS There was a rise in the proportion of double mutants of pvmdr1 and pvdhfr over time. Those cases with double mutant pvmdr1 gene in their isolates were found to have a prolonged hospital stay compared to those without, indicating reduced clinical response to chloroquine.

Abstract
Malaria caused by Plasmodium vivax is comparatively less virulent than Plasmodium falciparum, which can also lead to severe disease and death. It shows a wide geographical distribution. Chloroquine serves as a drug of choice, with primaquine as a radical cure. However, with the appearance of resistance to chloroquine and treatment has been shifted to artemisinin combination therapy followed by primaquine as a radical cure. Sulphadoxine-pyrimethamine, mefloquine, and atovaquone-proguanil are other drugs of choice in chloroquine-resistant areas, and later resistance was soon reported for these drugs also. The emergence of drug resistance serves as a major hurdle to controlling and eliminating malaria. The discovery of robust molecular markers and regular surveillance for the presence of mutations in malaria-endemic areas would serve as a helpful tool to combat drug resistance. Here, in this review, we will discuss the endemicity of P. vivax, a historical overview of antimalarial drugs, the appearance of drug resistance and molecular markers with their global distribution along with different measures taken to reduce malaria burden due to P. vivax infection and their resistance.
