Artemisinin-based combination therapy does not measurably reduce human infectiousness to vectors in a setting of intense malaria transmission (Publications)
n therapy (ACT) for treating malaria has activity against immature gametocytes. In theory, this property may complement the effect of terminating otherwise lengthy malaria infections and reducing the parasite [...] are common and cured patients are rapidly and repeatedly re-infected. METHODS: From 2001 to 2004, malaria vector densities were monitored using light traps in three Tanzanian districts. Mosquitoes were dissected [...] determined by ELISA. Sulphadoxinepyrimethamine (SP) monotherapy was...
<em>Plasmodium vivax</em> and mixed infections are associated with severe malaria in children: a prospective cohort study from Papua New Guinea (Publications)
prospective cohort study conducted within the framework of the Malaria Vaccine Epidemiology and Evaluation Project. All presumptive malaria cases presenting at two rural health facilities over an 8-y period [...] diagnosis of malaria associated with asexual blood stage parasitaemia and recent history of fits, or coma, or respiratory distress, or anaemia [haemoglobin < 5 g/dl]). Out of 17,201 presumptive malaria cases [...] BACKGROUND: Severe malaria (SM) is classically associated with Plasmodium...
A randomized placebo-controlled phase a malaria vaccine trial of two virosome-formulated synthetic peptides in healthy adult volunteers (Publications)
against the two malaria antigens were observed in the control group receiving unmodified virosomes. CONCLUSIONS: The present study demonstrates that three immunizations with the virosomal malaria vaccine components [...] further development of a final multi-stage virosomal vaccine formulation incorporating additional malaria antigens. TRIAL REGISTRATION: ClinicalTrials.gov NCT00400101
Virosome-formulated <em>Plasmodium falciparum</em> AMA-1 & CSP derived peptides as malaria vaccine: randomized phase 1b trial in semi-immune... (Publications)
evaluate the safety and immunogenicity of two virosome formulated malaria peptidomimetics derived from Plasmodium falciparum AMA-1 and CSP in malaria semi-immune adults and children. METHODS: The design was a [...] age-deescalating study with two immunizations. 10 adults and 40 children (aged 5-9 years) living in a malaria endemic area were immunized with PEV3B or virosomal influenza vaccine Inflexal(R)V on day 0 and 90 [...] from 4 to 66 in children. As an exploratory outcome, we found that the...
Age-patterns of malaria vary with severity, transmission intensity and seasonality in sub-Saharan Africa: a systematic review and pooled analysis (Publications)
P. falciparum clinical malaria, hospital admissions with malaria and malaria-diagnosed mortality. Studies were allocated to a 3x2 matrix of intensity and seasonality of malaria transmission. Maximum likelihood [...] falciparum malaria were concentrated in the youngest age groups across all settings. Despite recently observed declines in malaria transmission in several countries, which will shift the burden of malaria cases [...] for each outcome. Clinical malaria incidence was relatively evenly...
Comparative assessment of insecticide resistance phenotypes in two major malaria vectors, <em>Anopheles funestus</em> and <em>Anopheles... (Publications)
Long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS) have greatly reduced malaria transmission in sub-Saharan Africa, but are threatened by insecticide resistance. In south-eastern [...] rn Tanzania, pyrethroid-resistant Anopheles funestus are now implicated in > 80% of malaria infections, even in villages where the species occurs at lower densities than the other vector, Anopheles arabiensis [...] arabiensis. This study compared the insecticide resistance phenotypes...
Speech and language sequelae of severe malaria in Kenyan children (Publications)
impairments following severe malaria in Kenyan children. RESEARCH DESIGN: Cohort study comparing the prevalence of impairments in children exposed or unexposed to severe malaria. METHODS AND PROCEDURES: The [...] study recruited 25 children who had previously been admitted to hospital with severe falciparum malaria and 27 unexposed to the disease. Assessments of comprehension, syntax, lexical semantics, higher [...] at 8-9 years of age, at least 2 years after admission to hospital in children...
Randomised trial of SPf66 vaccine against <em>Plasmodium falciparum</em> malaria in children in southern Tanzania (Publications)
3 clinical fever episodes per year. Minimum estimated community rates for serious malaria (cerebral malaria or malaria and anaemia) affect approximatively 5% of all children. Under conditions of a field [...] current malaria control strategies using rapid diagnosis and treatment as well as methods to reduce the man-vector contact have had limited success. In Kilombero district (Southern Tanzania), malaria transmission [...] Malaria, especially that due to Plasmodium falciparum, is one of the...
