pyrimethamine

In conclusion, the present results suggest that SP could be effective in treatment against the erythrocytic stages of vivax malaria in Iran; however, the increased frequency of mutant haplotypes in Iran since 2006 is worrying and indicates the emergence of drug-tolerant/resistant P. vivax isolates in Iran in near future.

To assess the effect of intermittent preventive treatment with sulfadoxine and pyrimethamine (IPT-SP) on placental parasitemia and maternal and perinatal outcome.

The World Health Organization recently proposed conducting in vivo studies in pregnant women to evaluate molecular markers for detecting resistance precociously.

Pyrimethamine is an antimalarial drug that has also been used successfully to treat autoimmune diseases such as lymphoproliferative syndrome. In this work, the effect of pyrimethamine (PYR) on the production of free radicals in malaria-infected mice was studied to better understand the drug’s immunomodulatory properties. BALB/c and CBA/Ca mice were infected with Plasmodium yoelii 17XL.

The national policy change brought about a shift in treatment practice and the resulting increase in coverage had a substantial impact on drug pressure.

We tested whether chloroquine- and antifolate drug-resistant genotypes would be more commonly associated with cases of cerebral malaria than with cases of mild malaria in the province of Jabalpur, India, by genotyping the dhps, dhfr, pfmdr-1, and pfcrt genes using pyrosequencing, direct sequencing, and real-time PCR.

Sulfadoxine-pyrimethamine (SP) resistance in Plasmodium falciparum has been widespread across continents, causing the major hurdle of controlling malaria. Resistance is encoded mainly by point mutations in P. falciparum dihydrofolate reductase (pfdhfr) and dihydropteroate synthase (pfdhps) target genes.
