Half of people who think they have a food allergy do not – study
US study finds some people needlessly avoid foods while others do not have life-saving medicationThe number of adults who think they have a food allergy is almost double the figure who actually have one, research has revealed.While the study was conducted in the US, experts say a similar situation is also seen in other countries, including the UK.

High-affinity allergen-specific human antibodies cloned from single IgE B cell transcriptomes
Immunoglobulin E (IgE) antibodies protect against helminth infections but can also cause life-threatening allergic reactions. Despite their role in human health, the cells that produce these antibodies are rarely observed and remain enigmatic. We isolated single IgE B cells from individuals with food allergies and used single-cell RNA sequencing to elucidate the gene expression and splicing patterns unique to these cells. We identified a surprising example of convergent evolution in which IgE antibodies underwent identical gene rearrangements in unrelated individuals. Through the acquisition of variable region mutations, t...

Peanut allergy treatment around the corner but cost raises concerns
Scientists think treatment in which children take increasing doses of peanut protein will be approved next yearThe first medical treatment for children with peanut allergies is likely to be approved next year but there are concerns about its affordability, even though it consists essentially of peanut flour.A study in the US and at the UK ’s Evelina children’s hospital shows that gradually increasing a tiny initial dose of peanut protein over six months enabled two-thirds of children eventually to eat two peanuts without ill effects. The paper, published in the New England Journal of Medicine, followsa similar, smaller...

Allergies: the scourge of modern life?
Our ancestors didn ’t suffer from hay fever and food allergies were extremely rare even a few decades ago. What is causing the steep rise in their incidence now?To anyone from Generation X or older, it often feels like food allergies are far more common today than in their youth. While they remember them being rare or nonexistent in their school days, their own children will have classmates with allergies or they may have one themselves.According to theFood Standards Agency, estimates suggest that about 5-8% of children and 1-2% of adults are affected by food allergies in the UK. The recent headlines about fatal allergic...

Build 'Noah's ark' for beneficial gut microbes, scientists say
Repository would store ‘friendly’ germs from the intestines of people in remote communities for future medical treatmentsScientists have put forward plans for a microbial “Noah’s ark” to preserve beneficial bugs found in the guts of people living in some of the most remote communities on Earth.The move to save the microbes is driven by concerns that modern lifestyles are wiping out organisms that have colonised human intestines for millennia and are vital for good health.Continue reading...

The Allergy Epidemic
Publication date: 11 August 2018Source: New Scientist, Volume 239, Issue 3190Author(s): Penny SarchetMyths about allergies abound. Allergies are psychosomatic. Being too clean is causing allergies. Honey can cure hay fever… None of these statements is true. What is true is that possibly a quarter of us are afflicted by some form of allergy – and that number is on the rise. You might even be affected by one without realising. So how can we best deal with the allergy explosion? Penny Sarchet brings you the advice that's not to be sneezed at.

The surge in hay fever is rooted in our modern lifestyles
Obsessive hygiene, antibiotics and car exhausts are blamed for hay fever now affecting 20% of Britain ’s populationThis has been the worst month for hay fever for 12 years. Grasses had perfect growing conditions over late April and in May with warm sunshine and showers. That was followed in June by hot dry conditions when the grass flowers matured and shed clouds of pollen on light breezes and up people ’s noses.The strange thing is that hay fever was incredibly rare when it was first reported by John Bostoc, a London doctor, nearly 200 years ago. Yet in those days far more people lived and worked in the countryside, w...
