Molecular surveillance of pfhrp2 and pfhrp3 deletions in plasmodium falciparum isolates from mozambique

Malar. j. (Online); 16 (416), 2017
Background: Malaria programmes use Plasmodium falciparum histidine-rich protein-2 (PfHRP2) based rapid diagnos tic tests (RDTs) for malaria diagnosis. The deletion of this target antigen could potentially lead to misdiagnosis, delayed treatment and continuation of active transmission. Methods: Plasmodium...

Multiplexing detection of IgG against Plasmodium falciparum pregnancy-specific antigens

PLos ONE; 12 (7), 2017
Background: Pregnant women exposed to Plasmodium falciparum generate antibodies against VAR2CSA, the parasite protein that mediates adhesion of infected erythrocytes to the placenta. There is a need of high-throughput tools to determine the fine specificity of these antibodies that can be used to identif...

Resisting and tolerating P. falciparum in pregnancy under different malaria transmission intensities

BMC med; 15 (1), 2017
Resistance and tolerance to Plasmodium falciparum can determine the progression of malaria disease. However, quantitative evidence of tolerance is still limited. We investigated variations in the adverse impact of P. falciparum infections among African pregnant women under different intensities of malari...

Distinct Helper T Cell Type 1 and 2 Responses Associated With Malaria Protection and Risk in RTS, S/AS01E Vaccinees

Clin Infect Dis; 65 (5), 2017
The RTS,S/AS01E malaria vaccine has moderate efficacy, lower in infants than children. Current efforts to enhance RTS,S/AS01E efficacy would benefit from learning about the vaccine-induced immunity and identifying correlates of malaria protection, which could, for instance, inform the choice of adjuvants...

Efficacy and safety of artemether-lumefantrine for the treatment of uncomplicated falciparum malaria at sentinel sites in Mozambique, 2015

Acta trop.; 171 (1), 2017
he resistance of Plasmodium falciparum to anti-malarial drugs continues to challenge malaria control. We assessed the therapeutic efficacy and safety of artemether-lumefantrine (AL), the first-line treatment of uncomplicated P. falciparum malaria, in children under five years of age in Mozambique. We con...

In-vivo efficacy of chloroquine to clear asymptomatic infections in mozambican adults: a randomized, placebo-controlled Trial with Implications for Elimination Strategies

Recent reports regarding the re-emergence of parasite sensitivity to chloroquine call for a new consideration of this drug as an interesting complementary tool in malaria elimination efforts, given its good safety profile and long half-life. A randomized (2:1), single-blind, placebo-controlled trial was ...

Inquérito de Indicadores de Imunização, Malária e HIV/SIDA em Moçambique (IMASIDA)
Immunization Indicators Survey, Malaria and HIV/AIDS in Mozambique (IMASIDA)

O Inquérito de Indicadores de Imunização, Malária e HIV/SIDA (IMASIDA 2015) em Moçambique foi realizado com o objectivo de determinar a prevalência do HIV e SIDA e malária, bem como outros indicadores de saúde da mulher e da criança no país. O inquérito fornece dados a nível nacional, provinc...

A prospective cohort study to assess the micro-epidemiology of Plasmodium falciparum clinical malaria in Ilha Josina Machel (Manhiça, Mozambique)

Malar. j. (Online); 15 (444), 2016
After the decrease in clinical malaria incidence observed in Mozambique until 2009, a steady resurgence of cases per year has been reported nationally, reaching alarming levels in 2014. However, little is known about the clinical profile of the cases presented, or the possible epidemiological factors con...

Placental Microparticles and MicroRNAs in Pregnant Women with Plasmodium falciparum or HIV Infection

PLos ONE; 11 (1), 2016
During pregnancy, syncytiotrophoblast vesicles contribute to maternal tolerance towards the fetus, but also to pathologies such as pre-eclampsia. The aim of the study was to address whether Plasmodium falciparum and HIV infections in pregnancy affect the secretion, microRNA content and function of tropho...
