BACKGROUND The candidate malaria vaccine RTS,S/AS01 reduced episodes of both clinical and severe malaria in children 5 to 17 months of age by approximately 50% in an ongoing phase 3 trial. We studied infants 6 to 12 weeks of age recruited for the same trial. METHODS We administered RTS,S/AS01 or a comparator vaccine to 6537 infants who were 6 to 12 weeks(More)
BACKGROUND Approximately 46 million of the estimated 60 million deaths that occur in the world each year take place in developing countries. Further, this mortality is highest in Sub-Saharan Africa, although causes of mortality in this region are not well documented. The objective of this study is to describe the most frequent causes of mortality in(More)
INTRODUCTION Severe malaria has been attributed partly to the sequestration of Plasmodium falciparum-infected erythrocytes (IEs) in the microvasculature of vital host organs. Identification of P. falciparum cytoadherence phenotypes that are associated with severe malaria may lead to the development of novel strategies against life-threatening malaria. (More)
BACKGROUND Pneumonia is the major cause of mortality and morbidity in children worldwide. Procalcitonin (PCT) and C-reactive protein (CRP) are used in developed countries to differentiate between viral and bacterial causes of pneumonia. Validity of these markers needs to be further explored in Africa. METHODOLOGY AND PRINCIPAL FINDINGS We assessed the(More)
The factors involved in the progression from Plasmodium falciparum infection to severe malaria (SM) are still incompletely understood. Altered antibody and cellular immunity against P. falciparum might contribute to increase the risk of developing SM. To identify immune responses associated with SM, a sex- and age-matched case–control study was carried out(More)
BACKGROUND Intermittent Preventive Treatment (IPTp) and insecticide treated nets (ITNs) are recommended malaria in pregnancy preventive interventions in sub-Saharan Africa. Despite their cost-effectiveness and seemingly straight-forward delivery mechanism, their uptake remains low. We aimed at describing perceptions of pregnant women regarding malaria and(More)
Malaria is a leading cause of mortality, particularly in sub-Saharan African children. Prompt and efficacious treatment is important as patients may progress within a few hours to severe and possibly fatal disease. Chlorproguanil-dapsone-artesunate (CDA) was a promising artemisinin-based combination therapy (ACT), but its development was prematurely stopped(More)
BACKGROUND Pneumonia is a leading cause of childhood hospitalisation and child mortality in Africa. This study explores local interpretations of Acute Respiratory Infections (ARIs), focusing on caretakers of children under five in the context of hospital care seeking. METHODS The study took place in Manhiça, southern Mozambique and used Focused(More)
BACKGROUND Diarrheal disease remains a leading cause of illness and death, particularly in low-income countries. Its burden, microbiological causes and risk factors were examined in children aged 0-59 months living in Manhiça, rural southern Mozambique. METHODS Trends of diarrhea-related burden of disease were estimated during the period 2001-2012. A(More)
BACKGROUND Severe malaria is difficult to differentiate from other forms of malaria or other infections with similar symptoms. Any parameter associated to malaria-attributable severe disease could help to improve severe malaria diagnosis. METHODOLOGY This study assessed the relation between erythropoietin (EPO) and malaria-attributable severe disease in(More)
