People suffer from an allergy to peanuts may have a new technique to protect themselves from extreme allergic reactions to unintentional peanut publicity. It is known as sublingual immunotherapy or SLIT, and it entails placing a minuscule quantity of liquefied peanut protein beneath the tongue, the place it’s absorbed instantly into the bloodstream to desensitize the immune system to more significant amounts of peanut protein.
Published within the Journal of Allergy and Scientific Immunology, the analysis led by first writer Edwin Kim, MD, assistant professor of drugs on the UNC Faculty of Drugs, exhibits that SLIT may supply sufferers a safe and efficient strategy to defend themselves from extreme allergic reactions and even anaphylaxis.
“As a mum or dad of two youngsters with nut allergy symptoms, I do know the worry dad and mom face and the necessity for higher therapies,” mentioned Kim, member of the UNC Children’s Analysis Institute. “We now have the primary lengthy-time period knowledge displaying that sublingual immunotherapy is protected and tolerable, whereas providing a powerful quantity of safety.”
There are three predominant immunotherapeutic methods clinician-scientists have developed to deal with nut allergy symptoms, and all of them try to desensitize the immune system to nut proteins to assist sufferers in keeping away from extreme allergic reactions. Based on Kim, about 100 mg of peanut protein can set off a severe allergic response. That is the kind of hint quantity people fear can present up in meals “manufactured in a facility that processes peanuts.” For reference, one peanut kernel accommodates about 300 mg.
“The principle concept past immunotherapy just isn’t for youths to have the ability to eat peanut butter and jelly sandwiches,” Kim mentioned. “It is to maintain them secure from the small hidden exposures that might happen with packaged meals, at eating places, and with different meal exposures.”
