Is artemisinic acid a precursor of artemisinin ?

May 4, 2013 - 16:38 -- Pierre Lutgen

Two competing chemotypes.

Already twenty years ago the possibility of two chemotypes for Artemisia annua had been suggested ( HJ Woerdenbag et al., Flavour and Fragrance Journal 8, 1993, 131-137) distinguishing between a Chinese and a Vietnamese chemotype, the former containing 0.17 artemisinin, the latter 1.0%.

D Fulzele et al. ( Phytotherapy Research , 5, 1991, 149-153) found that plants from Europe produced the highest level of artemisin and those from Lucknow produced the highest level of arteannuin-B.

Call for preliminary scientific data for “high risk” project proposals?

May 3, 2013 - 09:30 -- Sombroek HLI

Why not let MalariaWorld play a vital role in supporting ground breaking studies that often lack the preliminary ecological field data, required by traditional funders?
We, as dedicated scientists, can assemble a global bank of preliminary scientific field data for “high risk” project proposals to open new directions within malaria research. In doing so, young scientists are able to test creative ideas ahead of time and more experienced scientists are able to explore unexpected and promising observations or discoveries.

World Malaria Day

April 25, 2013 - 07:08 -- Andre Laas

Today, 25 April marks World Malaria Day.

It is a day to reflect back on the progress that has been made in combating malaria around the globe and to contemplate future directions for research and control efforts to curb the impact and spread of this fully preventable and treatable disease that affects millions of lives on a daily basis. Let’s spare a thought for the countless lives that have been lost to this disease, and for the millions of people whose lives are affected at this very moment. May 2013 see more victories than defeats in the global fight against Malaria!

Why is WHO opposed to an effective anti-malarial tea ?

April 6, 2013 - 08:14 -- Pierre Lutgen

The following article was published in SLATE Magazine on April 4 by Brendan Borrell. Our association IFBV-BELHERB from Luxembourg is glad to read that some independent voices recognize the merit of Artemisia annua herbal medicine and proud to see that through R&D at their universities Africans will find their own solutions in the fight against tropical diseases. Hereafter excerpts from the paper. The full text is available at www.slate.com/.../wormwood_tea_to_treat_malaria

Is PCR genotyping of Plasmodium falciparum a reliable tool for monitoring drug resistance?

February 9, 2013 - 19:15 -- Pierre Lutgen

A recent press release from Wellcome Trust Sanger Institute raised a lot of concern. Based on a scientific paper published in Nature, 13 June 2012, it appears that a single infected person could harbour many genetically different Plasmodium falciparum parasites. The team from Oxford University found that these parasite populations easily swap DNA to create new forms.

This evidently raises the question how far PCR (polymer chain reaction genotyping) can distinguish between recrudescence (or treatment failure) and re-infection by new bites from anopheles mosquitoes.

Another interesting case

February 6, 2013 - 12:46 -- Ricardo Ataide

Pregnant woman arrives at the Maternity. She is worried because she had to leave her kids at home and the River Jurua is about to flood the area, so coming to the Maternity (which involves getting a boat lift from a neighbour and then walking 1.5 km)is a great deal. She is 31 weeks into her pregnancy. Two weeks ago she had a malaria episode, Pf, and was given Quinine and Clindamycin. Now she has diarrhea, lower abdominal pain, 9 g/dL of hemoglobin, 29% hematocrit.

Vaincre le paludisme

Dear all,
 
The IRD (French Institut de recherche pour le développement) has posted useful information on malaria, particularly for non malariologists and students. It is in French yet, but easily translatable or understandable.
 
 
Best,

Scientific research and local health services

January 18, 2013 - 04:41 -- Ricardo Ataide

In malaria endemic areas, researchers and basic health workers need to and often do find ways to join forces and complement each others work. Nevertheless, the prevalent idea among a few who are higher up in the health services is that researchers, like myself, are only there for the "kill". Some of the complaints are that we have a limited time-span in the area, we take joy in seeing a patient who provides us with some parasites and we ultimately take without giving in return. I think that these are usually the things we hear most (and mostly through the grapevine...).

Lessons learned from Zambia: Virtual chat with Phil Thuma today and tomorrow

January 10, 2013 - 16:57 -- Sophie Beauvais

Dr. Thuma"We have been fortunate to see a marked decrease (98%) in malaria case load in the Macha area over the past 10 years. While it is impossible to name one particular project or program that made this happen, we believe that the involvement of people at the community level has made a significant impact.

Artemisia annua prevents transmission of malaria from man to mosquito

December 30, 2012 - 17:12 -- Pierre Lutgen

In the human body the parasite injected into the bloodstream by the mosquito undergoes the transformation from the asexual plasmodium into the sexual gametocytes which the mosquito is going to pick-up during its blood meal. The killing effect of artemisinin on gametocytes is known since twenty years and was first mentioned in in vitro trials at the John Hopkins University. These results were confirmed in 1993 by research teams in China and India and mentioned in the document WHO/MAL/98.1086.

'The Epidemiology and Control of malaria in Palestine' by I Kligler1930

November 30, 2012 - 09:00 -- Anton Alexander

It may be of interest to readers of MalariaWorld that the long-forgotten, overlooked, but still relevant book by Dr I Kligler, published in 1930, entitled 'The Epidemiology and Control of malaria in Palestine' is now available without charge to be read in its entirety at www.kligler1930.com . Kligler was the architect in Palestine of probably the first successful national malaria-eradication campaign in the world, the campaign was begun in 1922 and it was conducted without vaccines and without reliance on mosquito bednets. The website includes the review in 1930 by Science Magazine.

In October 2013 the next Pan African MIM conference on malaria will be organised in Durban, South Africa. It follows after the MIM 2009 meeting that was held in Nairobi. Although this seems far ahead of us, at MalariaWorld we are planning to inform you in the best possible way about this upcoming event.

We will also liaise with the MIM secretariat to see how we can best inform you about the conference and provide you with all necessary information on time.
