Filter by:To assess the efficacy of both first-line antimalarial medications used for the treatment of uncomplicated Plasmodium falciparum malaria infections in two geographic regions in Liberia.
The purpose of this study is to assess the antimalarial activity, pharmacokinetics, and safety of MK-7602 in healthy adults following Plasmodium falciparum (P. falciparum) infection.
This study will assess the durability of protection of a single immunisation with the Genetically Attenuated Parasite 2 (GA2) against controlled human malaria infection by rechallenging previously immunised and protected participants from the CoGA study (NCT05468606)
Non-communicable diseases (NCDs) such as diabetes are increasing in countries where malaria transmission is common. This study aims to investigate the relationship between NCDs and parasitic infections in Cameroon. The investigators will assess the risk of malaria, as well as other parasitic diseases, in a prospectively followed group of adults with diabetes, compared with those without diabetes. Malaria parasites and intestinal worms will be tested using blood and stool collected at four time points during a one-year follow-up. In addition, this project will investigate how natural protection against malaria is affected by diabetes and other risk factors for heart diseases.
The differential and systematic diagnosis of malaria, dengue and chikungunya in patients with fever (≥38.5°C) of undetermined etiology would allow the identification of infection by these pathogens and thus limit the inappropriate use of antibiotics (discontinuation or non-initiation) and optimize the clinical management and prognosis of patients.
A cluster-randomized double-blinded control trial will be conducted in Uganda to demonstrate and quantify the protective efficacy (PE) of Mossie-GO, an active spatial repellent system disseminating transfluthrin, in reducing the prevalence of malaria in children ≤ 5 years of age, as determined by RDT positivity and confirmed by microscopy. The study's secondary objective is to measure the diversionary impact of the intervention on locally unprotected individuals and impact of the intervention on entomological correlates of transmission including vector densities, host seeking behaviour and insecticide resistance. This will be conducted using Centre of Disease Control (CDC) light traps in households, human landing catches and World Health Organisation (WHO) tube tests. Further data collection include household behavioural surveys, air sampling to quantify concentration of transfluthrin present in air, acceptability surveys and intervention safety monitoring. Recruited households will be monitored across baseline data collection and followed up for 2 disease transmission seasons, for up to 18 months. The devices will be distributed to all consented eligible households in the two study arms: intervention and control. Intervention arm devices will be provided with transfluthrin treated discs and refill transfluthrin discs at frequent enough intervals to provide sustained protection. Households in the control arm will receive blank discs with no active ingredient. Households will be asked to continue using other malaria prevention practices, such as the use of bed nets, as recommended by national policy.
The aim of this study is to perform a performance evaluation of novel diagnostic tools for detecting malaria in malaria-endemic countries. At the beginning of 2022, FIND launched a call for innovation with the distinct aim to identify malaria innovations that have the potential to address the technical and operational limitations of current malaria RDTs, particularly in view of the emergence of P. falciparum parasites with hrp2/3 deletions, the need for improved tools to identify all Plasmodium species and/or the need for improved surveillance. This study will generate valuable data on the performance of these novel non-HRP2-based tests and inform FIND and developers on technical and operational assay optimization requirements for accelerated access of these tools to market.
This study aims to evaluate the effectiveness of the use of adapted insecticide-treated mosquito nets combined with extended DHA-PQ-based seasonal chemoprevention for all ages and behavior change communication in reducing the burden of malaria in relation to standards of protection and care among students (taalibés) in the daaras (Koranic schools) of Touba, Senegal.
Malaria remains a major health problem, especially among children living in sub-Saharan Africa where more than 90% of the disease and deaths occur. Adding to this high burden among the children is the co-existence of parasitic worms in their intestines and urinary tract. The combined infection of malaria and parasitic worms in these children has additive adverse effects of anaemia, poor physical and cognitive development, and death. Existing control programmes for the parasitic worms are operating sub-optimally despite the 2012 London Declaration on Neglected Tropical Diseases (NTDs) of achieving 75% treatment coverage by 2020. On the other hand, a malaria prevention programme, called Seasonal Malaria Chemoprevention (SMC), introduced in the same year as the London Declaration on NTDs has achieved more than 75% treatment coverage and prevented 75-85% of cases of uncomplicated and severe malaria in children. The remarkable success of SMC has led to the recent WHO recommendation for its extension to other at-risk age groups and in highly seasonal malaria transmission settings outside the Sahel region. This encouraging development supports the need to explore the possibility of integrating helminth control programmes with other successful delivery platforms such as SMC. However, limited empirical evidence exists on an integrated approach that integrated the control of malaria and parasitic worms in a safe, acceptable, easy-to-deliver and effective manner. To address this knowledge gap, the investigators conducted a randomised controlled trial in the first stage of this project to establish the feasibility and safety of integrating helminth control with SMC among Senegalese children. This second stage will assess the effectiveness and cost-effectiveness of using SMC platform to deliver deworming drugs to preschool and school-aged children living in communities where the burden of malaria and parasitic worms is high in central Ghana. One thousand, two hundred children aged 1-14 years will be randomly assigned equally to two study communities where antimalarial (SMC) drugs and deworming drugs will be administered in combination to the children living in one study community, and antimalarial (SMC) drugs alone will be delivered to the children living in the second study community. The effectiveness of the combined delivery will be determined by checking whether the combined antimalarial and deworming drugs prevent anaemia in the children who receive the combined drugs compared to the children who receive antimalarial drugs only. We will also determine the cost and cost-effectiveness of this approach by estimating the incremental cost savings due to cases of moderate and severe anaemia averted by giving antimalarial and deworming drugs together to the children. The findings of this study would provide evidence to boost public health recommendations for an integrated control of malaria and parasitic worms among children living in the poorest countries of the world. The findings may also reinforce the empirical evidence that the future direction of healthcare systems in developing countries should be comprehensive health management rather than vertical management of a single disease.
The aim of this study is to determine the effectiveness of a new spatial repellent (called Mesh) at repelling multiple disease vectors and, reducing clinical malaria rates in temporary shelters and camp settings. The design of the study will be a two-armed cluster randomised trial. By conducting the research in challenging camp settings in the north of Nigeria, the MENTOR Initiative aims to determine whether Mesh can be effective in harsh camp conditions where communities are living in conflict area temporary shelters.
