Background: Chloroquine/primaquine is the current therapy to eliminate Plasmodium vivax infection in the Amazon region.
Aims: This study investigates CYP1A2, CYP2C8, CYP2C9, CYP3A4 and CYP3A5 genetic polymorphisms influence on cloroquine/primaquine treatment.
Patients & Methods: Generalized estimating equations analyses were performed to determine the genetic influence in parasitemia and/or gametocytemia clearance over treatment time in 164 patients.
Results: An effect of CYP2C8 low-activity alleles on treatment was observed (p = 0.01). From baseline to first day of treatment, wild-type individuals achieved greater reduction of gametocytes than low-activity allele carriers. CYP2C9 and CYP3A5 genes showed a trend for gametocytemia and parasitemia clearance rates.
Conclusion: Future studies should be performed to access the extent of CYP2C8, CYP2C9 and CYP3A5 gene polymorphisms influence on cloroquine/primaquine treatment.

Blood Transfusions for Chronic Malaria Anemia in Prisoners of War on the Thai-Burma Railway 1943-1945.

Allied prisoners of war (POWs) working on the Imperial Japanese Army's railroad from Thailand to Burma during 1943-1945 devised a blood transfusion service to rescue severely ill fellow prisoners who were otherwise unlikely to survive the war. Extant transfusion records (1,251 recipients, 1,189 donors) in ledger books held by the United Kingdom National Archives at Kew were accessed and analyzed. Survival to the end of the war in 1945 was determined from Commonwealth War Graves Commission records.

Plasmodium vivax is the predominant malaria parasite in Latin America. Its colonization history in the region is rich and complex, and is still highly debated, especially about its origin(s). Our study employed cutting-edge population genomic techniques to analyze whole genome variation from 620 P.

There are however indications that for tropical isolates, notably from Southeast Asia, the lower dose of 3·5 mg/kg is insufficient. Determining the most effective regimen to eliminate hypnozoites is needed to achieve elimination of this malaria parasite.
