New Type of Bed Net Could Help Fight Against Malaria

The latest figures from the World Health Organisation shows that in 2016 malaria infected about 216 million people across 91 countries, up from five million in 2015

Researchers have developed a new type of bed net with a specific combination of an insecticide and insect growth regulator that could prevent millions of cases of malaria.

The novel net, detailed in the journal The Lancet, contains a pyrethroid insecticide, which repels and kills the mosquitoes, and an insect growth regulator — pyriproxyfen — which shortens the lives of mosquitoes and reduces their ability to reproduce.

Compared to conventional nets, this new type of mosquito net reduced the number of cases of clinical malaria by 12 per cent.

In areas with new combination beds, there was also a 51 per cent reduction in risk of a malaria infective mosquito bite.

Children sleeping under the new bed nets were 52 per cent less likely to be moderately anaemic, which is a major cause of mortality in children under two years, the research showed.

“This new invaluable tool would enable us to tackle more efficiently this terrible and deadly disease that affects many children. If deployed correctly, we could certainly prevent millions of cases and deaths of malaria,” said principal investigator Alfred B. Tiono, from the CNRFP in Africa.

For the study, the team conducted a two-year clinical trial in Burkina Faso, West Africa, involving 2,000 children, aged between six months and five years.

In the trial, the conventional bed nets were replaced over time with the new combination nets in 40 rural clusters covering 91 villages, involving 1,980 children in 2014 and 2,157 in 2015.

The number of mosquito bites and incidence of clinical malaria in the participants were recorded by health clinics and the number of mosquitoes in the houses was tracked through monthly light traps.

“Malaria kills more than 400,000 people per year and infects more than 200 million, yet resistance to our frontline drugs continues to emerge,” said study lead researcher Jake Baum, Professor at Imperial College London, in UK.

“We may have to look beyond the chemistry shelf for new drugs, and natural remedies shouldn’t be off our watch list,” Baum added.

For the study, published in the journal Archives of Disease in Childhood, researchers from Imperial College London with school children test their family soup broths for activity against the malaria parasite.

Several of the soup broths, collected from traditional family recipes that originated around the world, showed activity against the malaria parasite Plasmodium falciparum, either by curbing its growth or preventing it from maturing.

The soup recipes had been passed down through the generations for the treatment of fever.

Five of the broths were able to curb growth of the parasite in its disease-causing stage by more than 50 percent.

In two of these, the inhibitory activity was comparable with that of a leading anti-malarial drug, dihydroartemisinin.

Four other broths were more than 50 percent effective at blocking the ability of the parasites to mature to a form that infects mosquitoes, potentially blocking the process of transmission.

Dihydroarteminisin contains artemisinin, which was isolated from a traditional Chinese herbal medicine.

According to the researchers, the study was carried out by students at Eden Primary School in North London.

The pupils brought in samples of homemade clear soup broths from family recipes from across Europe, North Africa, and the Middle East.

Filtered extracts of the broths were then tested against two stages of the parasite: when it can infect mosquitoes, and when it can cause the disease in humans.

The recipes for each of the broths varied.

They were vegetarian, chicken, or beef based, with no particular ingredient common to those with the strongest anti-malarial activity.

The active ingredients in the broths studied are yet to be identified and tested, the study said.

To move forwards, the active ingredients would need to be isolated, before tests of toxicology and effectiveness, first in human cells and later preclinical trials.

The researchers behind the study hope that they may discover new anti-malarial compounds in a similar way from the work looking at soup.

“It’s really interesting to find potential routes for future drug development in something like your grandmother’s soup,” Baum added. (IANS)
