Combination Drug Therapy Offers Hope For Malaria Treatment

05.01.2004


Two articles and a Commentary in this week’s issue highlight how combination therapy offers the best hope for tackling drug resistance for the millions of people worldwide affected by malaria.



Drug resistance is the main barrier to effective malaria treatment. Artemisinin (extract of sweet wormwood , commonly used in Chinese herbal medicine) and its derivatives, artemether and artesunate, are of potential importance as other malarial drugs have been associated with microbial resistance.

A meta-analysis by the International Artemisinin Study Group of 16 randomised trials (12 from sub-Saharan Africa, three from Thailand, one from Peru) shows that artesunate was highly effective in treating malaria when added to other antimalarial drugs. Around 6000 patients were participants in the studies. Artesunate decreased parasite failure by around 80% and doubled the rate of parasite clearance compared with patients given standard malaria treatment.


Patrick E Duffy and Theonest K Mutabingwa consider in an accompanying Commentary (p 3) the policy implications for the use of artemisinin combination treatment (ACT) in different countries. They comment: “Will ACT reduce malaria incidence and prevent the emergence and spread of drug-resistant parasites in Africa, as occurred in southeast Asia? Only additional research will answer these questions. However, because of differences in epidemiology and intensity of transmission, reducing malaria incidence in Africa will be challenging.”

A study from Vietnam in this week’s issue (p 18) also assesses combination treatment for malaria. Tran Tinh Hien and colleagues found that the new combination dihydroartemisinin-piperaquine, formulated in a single tablet, is highly efficacious in Vietnam, where multidrug-resistant parasites are common. Authors of the Commentary state: “Dihydroartemisinin-piperaquine has a cost advantage (US$1 for an adult treatment) that brings it within reach of many but not all consumers, and encourages funding agencies to sponsor programmes that deliver these needed medicines to poorer countries.”

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
