Efficacy of Artemisinin Combination Therapies for the Treatment of Uncomplicated P. Vivax in Pregnancy in Brazil (PAACT-PV)
Summary
The current treatment recommendations for P. vivax in pregnant and non-pregnant individuals are to use chloroquine; in non-pregnant patients this is followed by primaquine to prevent relapse. As primaquine can not be used in pregnant women, these women remain at risk of relapse. As there is increasing concern about chloroquine resistant P. vivax in this region, there is a need to identify alternative treatment options. The artemisinin combination therapies are recommended for use against P. falciparum infections in pregnant women after the 1st trimester; additional data are needed to support the use of these drugs against P. vivax.

Medical and Biotech [MESH] Definitions
Plasmodium Cynomolgi
A protozoan parasite that occurs naturally in the macaque. It is similar to PLASMODIUM VIVAX and produces a type of malaria similar to vivax malaria (MALARIA, VIVAX). This species has been found to give rise to both natural and experimental human infections.
Plasmodium Vivax
A protozoan parasite that causes vivax malaria (MALARIA, VIVAX). This species is found almost everywhere malaria is endemic and is the only one that has a range extending into the temperate regions.
Malaria, Vivax
Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.
Plasmodium
A genus of protozoa that comprise the malaria parasites of mammals. Four species infect humans (although occasional infections with primate malarias may occur). These are PLASMODIUM FALCIPARUM; PLASMODIUM MALARIAE; PLASMODIUM OVALE, and PLASMODIUM VIVAX. Species causing infection in vertebrates other than man include: PLASMODIUM BERGHEI; PLASMODIUM CHABAUDI; P. vinckei, and PLASMODIUM YOELII in rodents; P. brasilianum, PLASMODIUM CYNOMOLGI; and PLASMODIUM KNOWLESI in monkeys; and PLASMODIUM GALLINACEUM in chickens.
Malaria
A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.
