In spite of recent reductions in transmission, malaria continues to kill over half a million people annually. To assist in fighting the global burden of malaria, Kenya-based Oxford research team, the Malaria Public Health Department (MPHD) has spent the past decade analysing malaria risk, interventions, and control methods, to better define and target malaria. This research has been used to inform local governments, the World Health Organization (WHO), and international funding organisations about malaria risk, interventions and control methods to better define and target malaria.
Malaria in pregnancy causes the deaths of 200,000 newborns and 10,000 mothers annually. The Liverpool School of Tropical Medicine is the coordinating centre of the global Malaria in Pregnancy Consortium. LSTM-led research from 2007 has contributed to the World Health Organisation's (WHO) estimates of the global burden of malaria in pregnancy, showing that 125M pregnancies are at risk, more than double previous estimates. The Consortium has also contributed to a better understanding of the low uptake of existing interventions by pregnant women, and identification of the best prevention strategies. Consequently, WHO updated its policy recommendations in 2007on intermittent-preventive-treatment for prevention of malaria in pregnancy, adopted in 37 sub-Saharan countries, and in 2012, already adopted in 9 countries.
Malaria in Africa, traditionally diagnosed from fever symptoms, has been massively overdiagnosed, and other causes of fever missed. This research demonstrated the magnitude of overdiagnosis, undertook trials of rapid diagnostic tests, identified alternative bacterial diagnoses, completed economic appraisals and studied prescriber behaviour. The research underpinned a major change in policy by WHO (2010), substantial investments by the Global Fund to fight HIV, TB and Malaria (GFATM), and changed clinical practice, to direct antimalarials to malaria patients only. In one country alone, 516,576 courses of inappropriate artemisinin-based combination therapy (ACT) were averted, worth in excess of $1m.
Impact on health and welfare: The malaria screening assay allows early re-admittance of malaria-risk donors to blood donation programmes whilst maintaining protection against transfusion-transmitted malaria. Increasing the availability of safe blood for donation through use of the malaria assay saves lives.
Impact on commerce: The malaria EIA is the front-line assay in at least ten countries today. Almost 2.5 million tests have been sold in the REF impact census period through a number of distributors, including Bio-Rad worldwide, [text removed for publication].
Beneficiaries: Individuals requiring blood transfusions, national blood transfusion services and hospitals; commercial companies marketing the malaria EIA.
Significance and Reach: Over 700,000 assays are now performed per year in the UK, France, Belgium, Portugal, Spain, Italy, Netherlands, New Zealand and Australia. In the UK alone, more than 345,000 blood donations from malaria-risk donors have been cleared for clinical use.
Attribution: All research was led by Dr Jana McBride, Dr David Cavanagh, and Eleanor Riley, at the University of Edinburgh (UoE), except output [6] which was an international consortium to which UoE contributed recombinant malaria antigens and technical expertise.
Earth Surface Processes and Environmental Change (ESPEC) Research Group researchers have developed the Liverpool Malaria Model (LMM). When integrated with various short range and long term climate models as part of wider research into a complex cross cutting `grand challenge', the LMM helps decision makers understand when an area is likely to become at risk from malaria in short and over longer time frames by indicating which areas are likely to become centres for epidemics. The impact of the research has been to advance policy makers' awareness and understanding of this complex issue, enhancing their capacity to manage associated risks.
Research by the University of Oxford's Shoklo Malaria Research Unit (SMRU), Mae Sot (Thailand), has had a significant impact on the health outcomes of pregnant women and infants in malaria affected areas, with findings leading to major changes in World Health Organization recommendations for the prevention and treatment of malaria in pregnancy. Its studies have established the optimum treatment regimes (using artemisinin-based drugs) and have shown that early detection and treatment of malaria, including asymptomatic infection, during pregnancy prevents maternal mortality, morbidity, and improves the outcome of pregnancy.
Researchers at the Mahidol-Oxford Research Unit (MORU) in Thailand performed the first comparative trials to unambiguously show artemisinin resistance in Plasmodium falciparum parasites in western Cambodia, as well as its emergence on the Thailand-Myanmar border. These studies emphasised the importance of urgent containment, leading to rapid responses from the World Health Organization (WHO) and international governments for the tracking and containment of drug-resistant malaria.
Since 1997 University of Liverpool (UoL) investigators have led global research into malarial retinopathy, the fundus features associated with severe malaria. The work has propelled this phenomenon from little-known curiosity to an essential component in the diagnosis of cerebral malaria (CM) and has altered understanding of how CM causes coma and kills. It has changed medical practice of those diagnosing one of the commonest fatal diseases in tropical countries. Malarial retinopathy is now considered an essential clinical feature of CM aiding the appropriate management of coma in infants. This change in practice has expanded from African research settings to clinical practice required by WHO guidelines and disseminated in major clinical textbooks from 2008.
The University of Oxford's Professor Nick White and his colleagues successfully demonstrated the effectiveness of artemisinin (an ancient Chinese remedy) in the treatment of malaria. They also pioneered artemisinin-combination therapy (ACT), the most effective and fast-acting malaria treatment in the world. Responsible for saving hundreds of thousands of lives every year, ACT was recommended by the World Health Organization (WHO) in 2006 as the primary method of malarial treatment globally. Malaria kills more than half a million and affects over 225 million people every year.
Malaria kills around 650,000 children a year but can be prevented by killing the mosquito vectors. As mosquitoes become resistant to insecticides the prevention measures can become ineffective. Research at the Liverpool School of Tropical Medicine (LSTM) led by Professor Hemingway FRS has been instrumental in the development of current World Health Organisation (WHO) guidelines to manage resistance, and has led to improved resistance diagnostics and novel monitoring software to integrate entomological and human health outcomes. LSTM's research led to the creation of the Innovative Vector Control Consortium (IVCC) which was established as an independent Product Development Partnership (PDP) in 2008. New, longer lasting formulations of insecticides developed by IVCC are now in operational use, and several novel public health insecticides are under development.
