4 types of gut bacteria ‘could prevent asthma’October 7, 2015
Babies can be protected against asthma later in life if they acquire 4 types of bacteria in their gut before they are 3 months old, a study suggests.
Asthma rates have increased since the scarpe basket jordan 1950s and now affect up to 20% of children in western countries.
Increasing asthma rates
There are 5.4 million people in the UK currently receiving treatment for asthma. Although rates have plateaued since the 1990s, the UK has some of the highest rates in Europe.
The latest research by Canadian scientists is based on a study of 319 children whose gut bacteria was analysed at 3 months of age and 1 year.
They found that infants lacking 4 types of bacteria – Faecalibacterium, Lachnospira, Veillonella and Rothia – were at significantly higher risk of scarpe basket jordan developing asthma later in childhood.
The researchers confirmed these findings in mice and also discovered that newborn mice inoculated with the 4 types of bacteria developed less severe asthma.
The ‘hygiene hypothesis’
“This research supports the hygiene hypothesis that we’re making our environment too clean,” says co-author Professor Brett Finlay of the University of British Columbia. “It shows that gut bacteria play a role in asthma, but it is early in life when the baby’s immune system is being established.”
His colleague, Dr Stuart Turvey, adds: “This scarpe basket jordan discovery gives us new potential ways to prevent this disease that is life-threatening for many children. It shows there’s a short, maybe 100-day window for giving babies therapeutic interventions to protect against asthma.”
The researchers say that further studies involving large numbers of children are needed to confirm their findings.
The study is published in Science Translational Medicine.
Upsetting the immune system
Commenting on the findings in a statement, Dr Samantha Walker, director of research and policy at Asthma UK, says: “Asthma is a complex condition and this research suggests that the delicate balance of gut bacteria in our bodies affects our scarpe basket jordan immune systems and may have a role to play in why some people go on to develop asthma.
“However, much more research is needed to help understand what these findings mean in terms of providing advice for new parents, developing treatments and ultimately a cure for asthma, a condition that affects more than 1 million children in the UK.”
