Can Peanut Allergy Be Prevented
In 2017, the National Institute for Allergy and Infectious Disease issued new in order to define high, moderate and low-risk infants for developing peanut allergy. The guidelines also address how to proceed with introduction of peanut based on risk in order to prevent the development of peanut allergy.
The updated guidelines are a breakthrough for the prevention of peanut allergy. Peanut allergy has become much more common in recent years, and there is now a roadmap to prevent many new cases.
According to the new guidelines, an infant at high risk of developing peanut allergy is one with severe eczema and/or egg allergy. The guidelines recommend introduction of peanut-containing foods as early as 4-6 months for high-risk infants who have already started solid foods, after determining that it is safe to do so.
If your child is determined to be high risk, the guidelines recommend having them tested for peanut allergy. Your allergist may do this with a skin test or blood test. Depending on the results, they may recommend attempting to try peanut for the first time in the office. A positive test alone does not necessarily prove your child is allergic, and studies have shown infants who have a peanut sensitivity arent necessarily allergic.
Although parents want to do whats best for their children, determining what best means isnt always easy. So if your son or daughter is struggling with peanut allergies, take control of the situation and consult an allergist today.

First Study Of A New Immunotherapy Treatment For Peanut Allergy Launches
by Ellyw Evans26 April 2022
The study will compare immunotherapy using boiled peanut to conventional treatments with roasted peanut in desensitising children with peanut allergy.
A new study, the first of its kind, is comparing whether oral immunotherapy using hypoallergenic, boiled peanut is as effective at treating peanut allergy as more conventional approaches which use roasted peanut flour.
The BOPI-2 study, at Imperial College London, has been funded by the charity Action Medical Research and the Medical Research Council. The treatment uses oral immunotherapy, a process that involves the gradual introduction of very small but increasing amounts of a food allergen to induce desensitisation in peanut-allergic children and young people.
The aim is to re-train the body so that it does not react to peanut, allowing people with peanut allergy to lead more normal lives. While desensitisation is not a cure, evidence suggests that it could reduce the risk of severe allergic reactions in the future.
Dr Sharanya Nagendran, Research Fellow at Imperial’s National Heart and Lung Institute, comments: It is really hard for families and caregivers to make sure that a child with peanut allergy avoids eating peanut, and accidental reactions are common. The BOPI-2 study is the first to directly compare conventional oral immunotherapy to hypoallergenic boiled peanut, allowing treated children to lead more normal lives without fear of a severe reaction.

Is There A Cure For Nut Allergies
It is not a cure, but a new treatment for children with severe peanut allergies is helping to protect them from life threatening reactions. Surgeon Gabriel Weston visited Addenbrookes Hospital in Cambridge to see it in action.
Every year the number of allergy sufferers increases by 5% with half of all affected being children. For those unlucky enough to develop severe allergies a tiny degree of exposure to the substance theyre allergic to could trigger a life threatening reaction. Managing allergies like this can be difficult as it requires patients and their families to constantly monitor food labels and meal preparation and can cause considerable anxiety. However a new treatment being offered at Addenbrookes Hospital in Cambridge is changing all this for children with severe peanut allergies.
The treatment is a form of whats called immunotherapy. It aims to re-train the immune systems of peanut allergy sufferers which for some reason have learned to perceive peanuts as a serious threat. Exactly why this happens has always been something of a mystery, but new research suggests that the way we are first exposed to peanuts is important. The latest thinking, supported by recent results from a study called LEAP, suggests that we are more likely to develop a peanut allergy if our earliest exposure is through the skin rather than through the mouth. This kind of exposure prevents our immune system from learning that peanuts are safe to eat.
How Is Nut Allergy Treated
If you or your child has reacted to eating nuts, the first step is to see your doctor. They may send you to an allergy specialist who will do a skin or blood test to see what you are allergic to. You may be allergic to several different types of nuts.
There is no cure for nut allergy. The only proven treatment is to completely avoid exposure to the nuts you are allergic to. Research is underway into how to prevent nut allergies in people who may be at risk, and how to ‘switch off’ nut allergy using immunotherapy.
If you are at risk of anaphylaxis, you may be given an adrenaline autoinjector . You should also have an anaphylaxis action plan so you and everyone else knows what to do if you are exposed to nuts.

Can Peanut Allergies Be Cured Scientists Say Yes Using Probiotics
The prevalence of peanut allergies continues to skyrocket worldwide. In fact, it remains the fastest growing food allergy at the present time. Frequency in US schoolchildren alone more than tripled from 1997 to 2008. Unlike other food allergies, a peanut allergy is seldom outgrown and is also one of the most dangerous. Those suffering its effects typically must carry an EpiPen for emergency treatment of anaphylaxis.
In attempts to limit life threatening exposure, many schools have banned peanuts and all products containing them. This includes lunchboxes as well as school cafeterias and vending machines. Unrefined peanut oil and foods cooked in it are also a risk as some of the peanut protein can remain in the fat.

Is There A Cure For Food Allergies
While an intolerance can be cured in some cases with an extended elimination diet and careful reintroduction, an allergy cannot. Once a body is sensitized to a certain food ingredient, it will remain sensitive to it. There are some cases where children will grow out of their allergies with proper monitoring and testing, but many severe allergies that are discovered in childhood will follow them into adulthood.

How Food Allergies Work
Allergic reactions take place when your immune system perceives the food as a threat. Your body has learned to see certain food ingredients as threats for reasons that expertise the field still dont totally understand. Some deal with watery eyes and congestions, whereas others have wheezing and difficulty breathing, or swelling in the mouth and throat. Mild or severe, allergic reactions happen every time an allergen comes into contact with the body, and there is even research to suggest that they can get worse the more that you try to eat it.

What Tests Help Diagnose A Peanut Allergy
Your healthcare provider may use a blood test to diagnose a peanut allergy. A blood test called an immunocap radioallergosorbent checks the number of antibodies in your blood. A higher number of certain types of antibodies can indicate an allergy.
Your healthcare provider may also use a skin test to identify or rule out multiple types of allergies. During a skin test, your provider:
- Makes a few tiny needle pricks in your back or arm.
- Applies small doses of different types of allergens where you have needle pricks.
- Montiors your skin reaction and interprets them after 15 minutes.
Skin patches that become red and itchy indicate an allergic response. Your provider can use this information to diagnose allergies.
You may also have an oral food challenge. During an oral food challenge, you eat tiny, increasing amounts of a peanut-based product in your healthcare providers office. Your healthcare provider has emergency medication and equipment on hand in case you have an allergic reaction.
How Do I Evaluate The Pros And Cons Of Peanut Allergy Immunotherapy
Many people with a peanut allergy dont necessarily want to eat their allergen they simply want protection against accidental exposure.
Talk with your allergist about the pros and cons of peanut allergy immunotherapy and determine whether the benefits outweigh the risks, including any potential side effects. Discuss the differences in undergoing OIT with an office-prepared product or Palforzia.
For some patients, avoidance of peanut may be most appropriate and preferred. Just keep two epinephrine auto-injectors close by in case of an accidental exposure and have an anaphylaxis emergency plan in place.
For others, OIT may be recommended if accidental exposures to peanut result in severe allergic reactions of if they want to consume peanuts regularly as part of their diet.
What are your goals with immunotherapy? Why do you want to pursue this? When you focus in on that why, all the processes, protocols and procedures become clear to you and your decisions start to fall into place, Dr. Jones says.
If youre uncertain even after consulting with an allergist, ask to connect with a patient or family who recently underwent peanut allergy immunotherapy. Another perspective may help with your decision-making.

Peanut Allergy Cured In Majority Of Children In Immunotherapy Trial
Australian researchers hail breakthrough after life-changing tolerance persists for up to four years
Australian researchers have made a breakthrough in the treatment of peanut allergy in children.
A small clinical trial conducted at the Murdoch Childrens Research Institute has led to two-thirds of children treated with an experimental immunotherapy treatment being cured of their allergy. Importantly, this desensitisation to peanuts persisted for up to four years after treatment.
These children had been eating peanut freely in their diet without having to follow any particular program of peanut intake in the years after treatment was completed, said the lead researcher, Prof Mimi Tang.
Peanut allergy is the most common cause of anaphylaxis, a life-threatening allergic reaction, and one of the most common causes of death from food allergy.
To combat this Tang, an immunologist and allergist, pioneered a new form of treatment that combines a probiotic with peanut oral immunotherapy, known as PPOIT. Instead of avoiding the allergen, the treatment is designed to reprogram the immune systems response to peanuts and eventually develop a tolerance.
Its thought that combining the probiotic with the immunotherapy gives the immune system the nudge it needs to do this, according to Tang.
At the end of the original trial in 2013, 82% of children who received the immunotherapy treatment were deemed tolerant to peanuts compared with just 4% in the placebo group.
Children And Young People Set To Benefit From New Treatment For Peanut Allergy
Children and young people aged between 4 and 17 with a peanut allergy could be set to benefit from Palforzia, a new treatment which can help build up their tolerance to peanut, after NICE recommended its use in draft guidance published today .
23 December 2021
Peanut allergy is one of the most common food allergies in children and is estimated to affect between 0.5% and 2% of children in the UK.
Palforzia contains precise and gradually increasing amounts of peanut protein. It works by gradually increasing the bodys ability to tolerate small amounts of peanut and can help reduce the severity of allergic reactions after being exposed to peanut.
Professor Gillian Leng, chief executive at NICE said: An allergy to peanuts can have a severe impact on the lives of children, young people and their families and carers. While it is rare for a peanut allergy to be fatal in the UK, the consequences of accidental exposure to peanuts can be severe, with some people needing to self-administer adrenaline and have emergency care if they are exposed to peanut.
I am pleased that were able to recommend a treatment that could improve the quality of life for children and young people with a peanut allergy and their carers. It will also help to give their families or carers additional confidence their child will not have a severe reaction if they are exposed to peanut.

How Do I Find Current And Accurate Information About Peanut Allergy Immunotherapy Treatment Options
When considering OIT, its important to make sure youre accessing trustworthy sources of information, says Douglas Jones, MD, a board-certified allergist and immunologist and food allergy specialist from the Tanner Clinic in Layton, Utah.
With food allergy in general, there is so much information out there, and probably just as much misinformation, Dr. Jones says. Then you add food allergy treatment options such as immunotherapy on top of that, and sometimes you may think: Where do I go? How do I even make decisions about this?
Ask yourself: Are my sources of information credible and trustworthy? What online resources am I using and what websites am I going to? What social media outlets do I visit and are they trustworthy? Getting good solid information is the first step.
OIT should be done by allergists with expertise in food allergy and with experience in managing patients through every stage of immunotherapy. Be sure to ask your allergist about their experience and training with OIT and what steps are taken to maximize safety, Dr. Jones adds.
Changes In Food Allergy Treatment Approach
As food allergy numbers began spiking in the 1990s, doctors recommended that allergenic foods such as milk, eggs and peanuts be removed from the diets of children with a high risk of allergies.
That thinking began to change, though, as research showed that eliminating specific foods did not slow the development of food allergies.
Then came the groundbreaking Learning Early About Peanut allergy study in 2015. The study found that the development of peanut allergies decreased in at-risk children with an early introduction of the food.
It was completely the opposite of what we had believed, notes Dr. Hong.

Oral Immunotherapy Can Be A Game Changer For Many With Food Allergies
Charles FengDec. 11, 2019
Food allergies upend lives. In children, food allergies can scale back or completely stop participation in birthday parties, organized sports, and summer camps. Parents may need to reduce their work hours and homeschool their children. For adults, grocery shopping or eating out becomes an ordeal. Oral immunotherapy could change that.
Part of the difficulty with food allergies is their sheer unpredictability a life-threatening allergic reaction can occur at any moment, hidden in what looks to be a safe food. For some, this leads to psychological repercussions that include depression and anxiety.
A major problem with food allergies is that theres currently no cure for them. For the past few decades, all doctors could do was passively prescribe epinephrine pens the best way to rescue someone who is having a serious allergic reaction and recommend avoiding the allergenic food.
Up to 80% of kids outgrow milk and egg allergies, but only about 20% of peanut allergies resolve, meaning they become lifelong problems. Whats more, rates of food allergies have exploded over the past 20 years, such that were in the midst of a food allergy epidemic. At present, nearly 6 million children and 26 million adults in the United States have food allergies, and every year accidental ingestions result in 9,500 hospitalizations and several deaths.

Why Is This Study Important
This is the largest randomized controlled study ever done on oral immunotherapy for children with peanut allergies. Earlier studies were conducted on smaller numbers of children and did not compare those getting treatment to those who didnt. This 2014 study will pave the way for future research needed to answer many still unanswered questions, such as how long does the desensitization last, how well does it work on adults, and could this be used for other food allergies?
