Clinical trials in low-resource settings: the perspectives of caregivers of paediatric participants from Uganda, Tanzania and Kenya (Publications)
study investigates the experience of caregivers consenting on behalf of paediatric participants in a malaria vaccine clinical trial where participation enables access to free, high-quality medical care. METHODS: [...] interviewed a total of 78 caregivers of paediatric participants previously enrolled in a phase II or III malaria vaccine clinical trial in Uganda, Tanzania and Kenya. Interviews were qualitative and analysed using
Antigenicity and immunogenicity of a novel <em>Plasmodium vivax</em> circumsporozoite derived synthetic vaccine construct (Publications)
BACKGROUND: The circumsporozoite (CS) protein is a major malaria sporozoite surface antigen currently being considered as vaccine candidate. Plasmodium vivax CS (PvCS) protein comprises a dimorphic central [...] VK210 and VK247. We studied the natural immune response to this region in human sera from different malaria-endemic areas and its immunogenicity in mice. RESULTS: PvNR1R2 was more frequently recognized by

human cells. Examples are the enzymes of folate synthesis or of the nonmevalonate pathway in the malaria parasites. However, there are other ways how a drug can kill selectively. Of particular relevance [...] the host, as this is how the current frontrunners of parasite chemotherapy work. Artemisinins for malaria, fexinidazole for human African trypanosomiasis, benznidazole for Chagas' disease, metronidazole
New <em>in vitro</em> interaction-parasite reduction ratio assay for early derisk in clinical development of antimalarial combinations (Publications)
The development and spread of drug-resistant phenotypes substantially threaten malaria control efforts. Combination therapies have the potential to minimize the risk of resistance development but require [...] will significantly improve and streamline the economic development of new drug combinations for malaria and potentially also in other therapeutic areas.
Care seeking and treatment of febrile children with and without danger signs of severe disease in northern Uganda: results from three household... (Publications)
(danger signs) in rural communities are crucial for preventing complications and death from severe malaria, pneumonia, and diarrhea. We set out to determine the treatment-seeking practices and treatment patterns [...] of age with an acute febrile illness, with or without danger signs of severe disease, in a highly malaria-endemic area of northern Uganda. Three household surveys were conducted from November through December
Repositioning and characterization of 1-(pyridin-4-yl)pyrrolidin-2-one derivatives as <em>Plasmodium </em>cytoplasmic prolyl-trna synthetase... (Publications)
parasites at a selection pressure of 3 x IC50) constitute unfavorable features for treatment of malaria. However, potent blood stage and antischizontal activity are compelling for causal prophylaxis which [...] Encouraging preliminary off-target profile and oral efficacy in a humanized murine model of Pf malaria allowed us to conclude that 1-(pyridin-4-yl)pyrrolidin-2-one derivatives represent a promising starting
Anémie dans une école du Cambodge rural: détection, prévalence et liens avec les parasitoses intestinales et la malnutrition (Publications)
iron deficiency intestinal worms and malaria. A two month transversal study was conducted in a rural primary school in Battambang Province, Cambodia, in a malaria-free area. The main objective of the study
Anti-protozoal activity of aporphine and protoberberine alkaloids from <em>Annickia kummeriae</em> (Engl. & Diels) Setten & Maas (Annonaceae) (Publications)
BACKGROUND: Malaria, trypanosomiasis and leishmaniasis have an overwhelming impact in the poorest countries in the world due to their prevalence, virulence and drug resistance ability. Currently, there [...] there is inadequate armory of drugs for the treatment of malaria, trypanosomiasis and leishmaniasis. This underscores the continuing need for the discovery and development of new anti-protozoal drugs. Consequently
Parasitic infections, anemia and malnutrition among rural settled and mobile pastoralist mothers and their children in Chad (Publications)
Chad. Intestinal parasites were evaluated using direct fecal smears and the Kato-Katz technique. Malaria status was determined using Paracheck-Pf((R)) rapid diagnostic test, and anemia was assessed with [...] common protozoan. The hookworm prevalence was 14% (CI 8-20) in women and 18% (CI 13-23) in children. Malaria prevalence was low among women (1%, CI 0.5-2) and children (3% CI 2-5). No significant difference
