Milk, the forgotten antimalarial

May 19, 2014 - 13:30 -- Pierre Lutgen

It all begins in 1952 with the work of the Liverpool School of Tropical Medicine (BG Maegraith et al, British Medical Journal, 1952, 1382-3). They found that in rats inoculated with Plasmodium berghei and living on a diet of milk there was a strong suppression of the growth of the parasites. This was valid for retail whole cow’s milk, reconstituted dried milk from different origins and human milk. Most rats on normal laboratory diet died in a few days.

Second paper on economic benefits of malaria suppression

May 13, 2014 - 17:12 -- William Jobin


I appreciate the publication of my first paper on economic benefits from suppressing malaria in Africa, printed in the MWJ of 2014 v5 n4 and cited on the MWJ webpage. I demonstrated that the return on investment in malaria suppression was about 6.5 to 1, a really good investment, don't you think?

New publications from WHO GMP

May 13, 2014 - 08:30 -- MESA Alliance
Safety review of 8-aminoquinoline antimalarial medicines
Written by external authors, this document reviews published and unpublished studies about the safety of primaquine and its precursors, with particular attention to haemolytic anaemia in G6PD-deficient individuals. The study was prepared for and discussed at a 2012 meeting of the WHO evidence review group on the safety and effectiveness of single-dose primaquine as a P. falciparum gametocytocide.
Elimination scenario planning
WHO has published a manual to help malaria-endemic countries to assess the feasibility of moving towards elimination. The new guide provides a comprehensive framework to assess different scenarios and timelines for reducing the disease burden and moving towards elimination, depending on programme coverage and funding availability.

Artemisia sieberi and bicarbonate : a revolutionary mixture from Palestine

May 11, 2014 - 18:48 -- Pierre Lutgen

The mode of action of quinine and chloroquine is almost exclusively based on the inhibition of the crystallization of heme into hemozoin, killing plasmodium in its own digestive rejects. In several papers M Akkawi from the Al Quds University in Palestine has shown that extracts of several medicinal plants : Salvia officinalis, Artemisia sieberi, Artemisia afra, Artemisia annua, Inula viscosa had similar effects, in some cases equivalent or better than chloroquine for the inhibition of beta-hematin (see literature references below).

Column: The IPCC, malaria and climate change: neither scaremongering or ignorant

May 8, 2014 - 18:51 -- Bart G.J. Knols
I freely admit that I have not read all 2155 pages of the draft report by the International Panel on Climate Change (IPCC) released last month. Furthermore, I am not an expert on global climate change. However, motivated by this report and a recent comment posted to MalariaWorld entitled ‘IPCC, malaria and climate: scaremonging or ignorance’ (1), I will try to relate the IPCC assessments of climate change to malaria and the future...

Column: Mass Drug Administration – A Kaleidoscope of New Opportunities?

May 5, 2014 - 20:19 -- Bart G.J. Knols

Mass Drug Administration (MDA) is a tantalizing tool that can support elimination efforts and help dramatically knock down malaria prevalence.  Why isn’t it more widely used?

by George Jagoe

The use of medicines on a mass scale to wipe out parasite reservoirs and improve individual patient health status is enormously appealing.   The annals of public health victories show how judicious mass-drug-administration (MDA) has rolled back the burden of horrific parasitic diseases (e.g. river blindness, lymphatic filariasis, trachoma).    At its best, MDA marries the optimal use of effective drugs with well-coordinated delivery to improve disease outcomes radically...

Rotary in support of Artemisia annua

May 3, 2014 - 17:33 -- Pierre Lutgen

In the April 2014 issue the magazine Rotary Contact from Belgium-Luxembourg duly recognized he efforts and results achieved by Rotarians from Ieper and Luxembourg in the promotion of Artemisia annua tea against malaria. Geert Flamang has launched plantations in Katanga and Pierre Lutgen has run clinical trials in several African countries which demonstrate an efficiency of >95%. These trials have allowed to show that the antimalarial potency can be increased by using the dried leaves in lieu of aqueous extracts, as powder in capsules or mixed with food.

Jerusalem declaration on malaria elimination in Africa

April 24, 2014 - 19:46 -- J20 Jerusalem Conf

Almost a century after Dr. Israel Kligler initiated a malaria elimination campaign in Mandate Palestine, the undersigned met in Jerusalem to honour his exemplary approach that consisted of an integrated attack on malaria that ultimately led to its disappearance. 
In many ways, the disease burden of malaria in Africa today resembles that of Palestine when Kligler first arrived. His success – a toolbox that included larval mosquito control, swamp drainage, quinine prophylaxis and treatment, community education - played a major role in making the Holy Land habitable and productive.

Why this 2013 Jerusalem conference?

April 24, 2014 - 19:46 -- J20 Jerusalem Conf

Learning from Success

Over the past 60 years, conferences on malaria have increased from maybe one per decade to multiple conferences annually. The 1950 Kampala Malaria Conference set the parameters for the 1955 Global Malaria Eradication Programme, followed 40 years later, 1992 and 1996, with the meetings in Dakar and Amsterdam that galvanised WHO and international support to eradicate malaria. Roll Back Malaria, the Global Fund, the Gates Foundation and other major international donors took us to the 21st century goal of malaria elimination.

This week it's World Malaria Day: Read the Jerusalem Declaration on Sustainable Malaria Elimination in Africa

April 22, 2014 - 19:00 -- Bart G.J. Knols
This week it's World Malaria Day. A day during which, around the world, activities are undertaken to raise awareness for our cause: a world free of malaria. A day to reflect: How are we progressing towards our goal? A day to talk to our friends about what we do - raise awareness. A day also to celebrate the successes of the last decade - no doubt, these are impressive. But also a day to tell the world that without investments, serious investments, progression towards global eradication will slowly grind to a halt. A day to appeal with our governments and other funding bodies that the challenge is still huge, but that we cannot give up. We started with the 'e-words' in October 2007 in Seattle, now we have to live up to our pledge...

New: MESA operational research grants start activities

April 10, 2014 - 22:15 -- MESA Alliance

New operational research projects in malaria elimination will start this April, after being selected for funding through MESA. The MESA operational research portfolio includes: proof-of-concept of novel vector control and diagnostic tools, use of mapping technologies for surveillance and tailored response, and mobile phone applications for hard to reach populations. Urban, rural and forest settings are addressed. The projects are summarised here.

Column: What do health professionals in Europe know about malaria? ‘Part I: European statistics’

April 10, 2014 - 20:00 -- Ingeborg van Schayk

Four years ago, after working for six years as a hospital and pre-hospital emergency doctor in Spain, I accepted a position as a remote site doctor in Sierra Leone. Until then malaria was an obscure, almost phantasmagorical, condition to me.

Column: Where do you hang a mosquito net in the bush?

April 2, 2014 - 19:22 -- Bart G.J. Knols
So you live in DR Congo. Your youngest child has visited the health post today, she is diagnosed with malaria. You were lucky that there was somebody at the clinic today. They gave you a blister with drugs. It is not quite clear how you got the first capsule into this two year old, but you managed. She is asleep now, safely under a mosquito net that was donated to you last year.
All of a sudden you hear noise outside. Gunshots, men running, men screaming. You know what this means. You, your family, you have to run. NOW.

Column: Social values & beliefs: the key to successful malaria prevention?

March 23, 2014 - 08:46 -- Ingeborg van Schayk
Do social norms and cost sharing matter in obtaining community buy in and adding value to health commodities? An excerpt from the field with emphasis on community based participatory methods and insecticide treated bed net (ITN) usage.

Are in vitro antimalarial assays a waste of time?

March 22, 2014 - 08:59 -- Pierre Lutgen

by Patrick Engeu Ogwang and Pierre Lutgen

Most of the assessments on the antimalarial efficacy of a molecule are made in vitro. In the case of plant material the first step is generally the extraction with an organic solvent. The extract is then lyophilized, frozen and stored for subsequent trials.

In memoriam: Ernst-Jan Scholte (1974 - 2014)

March 20, 2014 - 19:00 -- Bart G.J. Knols

It is with great sadness that I report the passing of my friend, colleague and my former PhD student Dr. Ernst-Jan Scholte, yesterday, 16 March 2014. Although obituaries are normally written for scientists that died at an old age and had a massive track record in our field, I feel the urge to commemorate and remember this great person in front of you all at MalariaWorld. He became only 40 years of age - after fighting cancer for a year.

Ernst-Jan first contacted me in 1998 when he was still a biology student at the Wageningen University. At that time I was working in Nairobi for the International Centre of Insect Physiology and Ecology (ICIPE). Ernst-Jan (or EJ as many called him) wanted to study mosquitoes and do an internship with me for six months. He was lucky. Within a week after he arrived in Kenya we undertook a wonderful safari to the border with Tanzania, visiting and hiking in a Masai area where I had previously worked on tsetse flies. EJ loved it from day one. He fell in love with Africa, its people and its wildlife, and was extremely motivated in his work. I will never forget the nights we camped out in the bush together...

New: Book on architecture and health (notably malaria)

March 20, 2014 - 18:14 -- Bart G.J. Knols
Early nomadic shelters, including caves, animal skin tents, and igloos, were used for protection against the wind, rain, snow, sunlight, and other forces of nature. These basic homes also provided defence against predators and were used to store a few important possessions. They were temporary, and proximity to a water source was of prime importance.

International Innovation, has recently published an edition called 'Parasites of poverty: how international research is tackling the global threat of tropical disease'. In this edition there is a special focus on malaria: 'break the life cycle stop the spread."

Column: Out of sight, out of mind? How has imaging advanced our understanding of Plasmodium infected erythrocytes?

March 12, 2014 - 21:57 -- Bart G.J. Knols
Being a lab-based malaria researcher in a non-endemic country, I’ve been really interested by the columns that our colleagues ‘in the field’ have shared; looking at vector populations, elimination strategies and experiences of disease themselves. My perspectives of malaria are rather different however, and I hope to share more of a laboratory angle in my contributions to MalariaWorld this year. With that in mind, where better to start than the microscope and how most of us first come ‘face to face’ with Plasmodium spp? 
A bit of history
Much of our knowledge of Plasmodium parasites has come from the ability to visualize them (reviewed by [1]). The first description of the causative agents of malaria by Laveran in 1880 was made possible by 400x magnification of infected blood samples, and detected the pigment we now know as haemozoin. Since then the Giemsa stain, developed in 1904, has made it possible to differentiate between species, and remains the clinical gold standard to diagnose infection...

Column: Problems on the Horizon

March 2, 2014 - 22:08 -- Bart G.J. Knols
As an avid observer of malaria transmission patterns, I am becoming worried about sustaining the advances that have developed over the past ten or so years. There is no doubt that the advent of insecticide treated bednets has provided a vehicle for various interested parties to exploit as a means of vector control, and this has happened in huge numbers. Tens of millions of LLINs have been delivered to various governments, NGOs and other interested parties, and this is still happening. But when it comes to monitoring the effects of this intervention, when it comes to careful evaluation of the programmes, there isn’t much to hear...

Can malaria be suppressed in the Congo River Basin without developing the Grand Inga Dam?

February 28, 2014 - 12:50 -- William Jobin


Despite real progress in much of Africa, the two big elephants left in the room are Nigeria and the Congo. Because of poor infrastructure, continuing civil war, and very unstable political conditions, it is hard to imagine how we can attack malaria in the Congo. Although the US PMI has added them to their list, we all know it will be a long time before anything significant can be organized there.

Organizing indoor spray programs or bednet distribution takes a stable MOH, and is difficult in the midst of civil war.

World Health Day (7 April) about vector-borne diseases

February 24, 2014 - 19:50 -- Bart G.J. Knols

This year World Health Day has its focus on vector-borne diseases, including malaria. The World Health Organization has set specific goals for this day, and is asking the international community working on malaria and other vectors to pay special attention towards protection from vector-borne diseases.

Avez-vous travaillez avec le PMI en Afrique ? Have you worked with US Presidential Malaria Initiative for Africa?

February 21, 2014 - 13:00 -- William Jobin

Chers Confreres et Colleagues,

The US Presidential Malaria Initiative (PMI) began in 2005 in Angola. I helped start it, along with 2 other consultants for RTI the US contractor, and 3 malariologists from the Angolan Ministry of Health. Since then PMI has expanded to cover 21 countries in Africa. The contract passed from RTI to Abt Associates, and others.

If you do simple math, that means we have accumulated about 1,000 person years since then, in Africa, fighting malaria. What a tremendous resource! Are you one of those people?
