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...

Changing Trends in P. falciparum Burden, Immunity, and Disease in Pregnancy

N. Engl. j. med; (), 2015
Background: Prevention of reinfection and resurgence is an integral component of the goal to eradicate malaria. However, the adverse effects of malaria resurgences are not known. Methods: We assessed the prevalence of Plasmodium falciparum infection among 1819 Mozambican women who delivered infants betwe...

In vivo efficacy of artemether-lumefantrine and artesunate-amodiaquine for the treatment of uncomplicated falciparum malaria in children: a multisite, open-label, two-cohort, clinical trial in Mozambique

Malar. j. (Online); 13 (309), 2014
Background: Mozambique adopted artemisinin-based combination therapy (ACT) for the treatment of uncomplicated Plasmodium falciparum malaria in the year 2006, and since 2009 artemether-lumefantrine (AL) and artesunateamodiaquine (ASAQ) have been proposed as alternative first-line treatments. A multicentre...

Duration of vaccine efficacy against malaria: 5th year of follow-up in children vaccinated with rts, s/as02 in mozambique

Vaccine; 32 (19), 2014
A primary concern for the RTS,S malaria vaccine candidate is duration of protection. The ongoing Phase III trial reported evidence of waning efficacy within the first year following vaccination. Multiple Phase IIb trials demonstrated early waning of efficacy. The longest duration of protection for RTS,S ...

Impact of age of first exposure to Plasmodium falciparum on antibody responses to malaria in children: a randomized, controlled trial in Mozambique

Malar. j. (Online); 13 (121), 2014
Background: The impact of the age of first Plasmodium falciparum infection on the rate of acquisition of immunity to malaria and on the immune correlates of protection has proven difficult to elucidate. A randomized, double-blind, placebo-controlled trial using monthly chemoprophylaxis with sulphadoxine-...

Severity of anaemia is associated with bone marrow haemozoin in children exposed to Plasmodium falciparum

Br. j. haematol; 164 (6), 2014
There are no large-scale ex vivo studies addressing the contribution of Plasmodium falciparum in the bone marrow to anaemia. The presence of malaria parasites and haemozoin were studied in bone marrows from 290 anaemic children attending a rural hospital in Mozambique. eripheral blood infections were det...

Increased Severity and Mortality in Adults Co-Infected with Malaria and HIV in Maputo, Mozambique: A Prospective Cross-Sectional Study

PLos ONE; 9 (2), 2014
Background: Co-infection with falciparum malaria and HIV-1 increases the severity and mortality of both infections in unstable malaria-transmission areas. In contrast, in stable transmission areas, HIV co-infection increases the severity of both infections but has not been found to influence malaria mort...
