Summary
Plasmodium knowlesi is a form of monkey malaria recently found to also cause increasing numbers of natural infections in humans in South-East Asia. This research will describe the burden of P. knowlesi malaria in an area of Malaysian Borneo. The risk factors for acquiring P. knowlesi malaria will be assessed. Finally the optimal treatment for non-severe cases of P. knowlesi and P. vivax malaria will also be evaluated by comparing the 2 currently recommended anti-malarial medications in Malaysia.

Summary
Dr Karunajeewa is an expert in the treatment of malaria and other infectious diseases that have a major impact on the health of people living in developing countries of the tropical zone of the Asia-Pacific region. His ongoing research aims to develop better ways of diagnosing these infections, defining their relative importance in terms of overall burden of disease, finding optimal drug treatments and testing the effectiveness of new vaccines for their prevention.

Summary
The monkey parasite P. knowlesi is an increasing cause of human malaria in SE Asia. My studies on the clinical epidemiology, diagnosis and treatment of non-severe and severe malaria in Malaysia have changed policy. I will further define the clinical epidemiology of malaria patients in this area over time, assess risk factors for knowlesi malaria, and evaluate the role of human and parasite factors in disease severity, and treatment for reducing acute kidney injury in knowlesi malaria.

Summary
Malaria represents a significant global health burden in endemic countries. Individuals gradually develop a level of immunity to the clinical symptoms of malaria as a result of continued exposure throughout their lifetime. Efforts to implement effective malaria control strategies are increasing, thereby reducing exposure. This project will investigate how such strategies will impact on the development of immunity to malaria and the amount of clinical disease observed in different age groups.
I am a public health physician and medical parasitologist determining the mechanism of clinical immunity to malaria, and working on the development of vaccines and therapies against malaria.
A Safety, Tolerability, Pharmacokinetic And Efficacy Study Of Azithromycin Plus Piperaquine As Intermittent Presumptive Treatment In Pregnant Papua New Guinean Women

Summary
The purpose of this research is to investigate a new antimalarial combination therapy, azithromycin (AZI) plus piperaquine (PQ), for the prevention of malaria infection in pregnant Papua New Guinean women. It is anticipated that these studies will provide sufficient data to determine if AZI-PQ is a suitable alternative treatment option in PNG, and other countries which have similar malaria epidemiology including the presence of drug resistant parasites.
Loop-mediated Isothermal Amplification(LAMP): A Novel Tool For The Diagnosis Of Mixed Malaria Infections In Elimination Settings

Summary
The malaria elimination agenda will require the development of novel, field applicable diagnostic tools to detect asymptomatic carriers of P.falciparum and non-falciparum malaria infections. Loop-mediated isothermal amplification (LAMP) has been demonstrated to be a novel, sensitive, specific nucleic acid amplification technique. My project aims to optimise LAMP into a high-throughput field applicable molecular diagnostic tool capable of diagnosing malaria in elimination settings
The Role Of The Innate Immune System In The Immunopathogenesis Of Malaria

Summary
Malaria is common worldwide, affecting 600 million people. As with many infectious diseases, it the severity of a malaria infection is not only dictated by the parasite, but also the body’s immune response to the infection. This study looks at cells that contribute to the immediate immune response in two major clinical syndromes of malaria affecting women and children: cerebral malaria and malaria of pregnancy. By understanding the immune response, we gain insights into how to limit disease.
Targeting Microvascular Dysfunction In Severe Malaria

Summary
In severe malaria blood vessels cannot make enough protective nitric oxide (NO). The gel-like lining of blood vessels (glycocalyx) is needed to produce NO, but this is damaged in some severe infections. We will test whether glycocalyx is lost in malaria and how it affects blood vessel NO and function in human volunteer infections and in patients with and without severe malaria. We will test whether a salt nitrite, can be used to safely increase NO and blood vessel function in severe malaria.

Summary
Malaria remains a major problem for children in developing countries especially where different types of the disease are common. This set of complementary studies, based at an established research site in PNG aims to develop new treatment strategies for childhood malaria. A novel method of giving medicine via a spray under the tongue for sick children before arrival at hospital and modified dosing schedules of an old drug used for treating parasites hidden in the liver will be studied.
