Persistence of Plasmodium falciparum parasites in infected pregnant Mozambican women after delivery

Infect. immun; 97 (1), 2010
Pregnant women are susceptible to Plasmodium falciparum parasites that sequester in the placenta. The massive accumulation of infected erythrocytes in the placenta has been suggested to trigger the deleterious effects of malaria in pregnant women and their offspring. The risk of malaria is also high duri...

Falciparum malaria and HIV-1 in hospitalized adults in Maputo, Mozambique: does HIV-infection obscure the malaria diagnosis?

Malar. j. (Online); 7 (252), 2008
Background: The potential impact of HIV-1 on falciparum malaria has been difficult to determine because of diagnostic problems and insufficient epidemiological data. Methods: In a prospective, cross-sectional study, clinical and laboratory data was registered consecutively for all adults admitted to a me...

Impact of intermittent preventive treatment with sulfadoxine-pyrimethamine on antibody responses to erythrocytic-stage Plasmodium falciparum antigens in infants in Mozambique

Clin. vaccine immunol; 15 (8), 2008
We evaluated the impact of intermittent preventive treatment in infants (IPTi) with sulfadoxine-pyrimethamine (SP), which was given at ages 3, 4, and 9 months through the Expanded Program on Immunization (EPI), on the development of antibody responses to Plasmodium falciparum in Mozambique. Immunoglobuli...

Rapid increase of Plasmodium falciparum dhfr/dhps resistant haplotypes, after the adoption of sulphadoxine-pyrimethamine as first line treatment in 2002, in southern Mozambique

Malar. j. (Online); 7 (115), 2008
In late 2002, the health authorities of Mozambique implemented sulphadoxine-pyrimethamine (SP)/amodiaquine (AQ) as first-line treatment against uncomplicated falciparum malaria. In 2004, this has been altered to SP/artesunate in line with WHO recommendations of using Artemisinin Combination Therapies (AC...

Malaria in rural Mozambique. Part II: children admitted to hospital

Malar. j. (Online); 7 (37), 2008
Background: Characterization of severe malaria cases on arrival to hospital may lead to early recognition and improved management. Minimum community based-incidence rates (MCBIRs) complement hospital data, describing the malaria burden in the community. Methods: A retrospective analysis of all admitted m...

Safety of the RTS,S/AS02A malaria vaccine in Mozambican children during a Phase IIb trial

Vaccine; 26 (2), 2008
RTS,S/AS02A is a pre-erythrocytic vaccine candidate based on the Plasmodium falciparum circumsporozoite surface antigen and is currently the most advanced malaria vaccine candidate in development.

Prevalence and predictors of maternal peripheral malaria parasitemia in central Mozambique

Am. j. trop. med. hyg; 77 (2), 2007
Malaria infection during pregnancy (MiP) is heterogeneously distributed even in malaria-endemic countries. Program planners require data to facilitate identification of highest-priority populations for MiP control. Using data from two cross-sectional studies of 5,528 pregnant women in 8 neighboring sites...
