Peanut allergy affects even more U.S. adults than children
Peanut allergy affects at least 4.5 million adults in the U.S., many of whom report developing their first allergy symptoms during adulthood. Although three out of four Americans with peanut allergy are over 17 years old, peanut allergy is often considered a predominantly pediatric concern. There are currently no FDA-approved therapies for patients with adult-onset food allergy. (2021-02-09)

Researchers identify a new molecular mechanism related to severe anaphylaxis
In a study led by researchers of the University of Barcelona and IDIBAPS, researchers analyzed the mutation of a gen detected in a patient who suffered from recurrent anaphylactic shocks caused by the allergy to paper wasp venom (Polistes dominula). The results, published in the Journal of Allergy and Clinical Immunology, revealed a new molecular mechanism that can control the degree of severity in an anaphylactic reaction. (2021-02-09)

Novel immunotherapy approach to treat cat allergy
Researchers from the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH) brought forward the potential of high doses of a specific adjuvant molecule, namely CpG oligonucleotide, in successfully modulating the immune system's allergic response to the main cat allergen Fel d 1, thereby inducing a tolerance-promoting reaction and reverting the main hallmarks of cat allergy.

NIH-funded study examines mono, chronic fatigue syndrome in college students
Many college students fully recover from infectious mononucleosis (which is almost always caused by Epstein-Barr virus) within 1-6 weeks, but some go on to develop chronic fatigue syndrome, also called myalgic encephalomyelitis (ME/CFS). A longitudinal study from DePaul University and Northwestern University followed 4,501 college students to examine risk factors that may trigger longer illness. (2021-01-22)

Acute itching in eczema patients linked to environmental allergens
New research from Washington University School of Medicine in St. Louis indicates that allergens in the environment often are to blame for episodes of acute itch in eczema patients, and that the itching often doesn't respond to antihistamines because the itch signals are being carried to the brain along a previously unrecognized pathway that current drugs don't target. (2021-01-14)

Scientists reveal mechanism that causes irritable bowel syndrome
KU Leuven researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods.

Pollen levels might trigger flares of urologic chronic pelvic pain
As anyone living with hay fever can attest, days with high pollen counts can bring attacks of sneezing, nasal congestion and other allergy symptoms. Now, a new study suggests rising pollen levels may also trigger flare-ups of pain and other symptoms in patients with urologic chronic pelvic pain syndrome (UCPPS), reports The Journal of Urology®, Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer. (2021-01-05)

Allergists offer reassurance regarding potential allergic reactions to COVID-19 vaccines
Reports of possible allergic reactions to COVID-19 vaccines have raised public concern; however, allergists note that allergic reactions to vaccines are rare, and COVID-19 vaccine allergic reactions will have a similarly low rate of occurrence. Individuals with a history of anaphylaxis to an injectable drug or vaccine containing polyethylene glycol or polysorbate should speak with an allergist before getting vaccinated, but patients with severe allergies to foods, oral drugs, latex or venom can safely receive the COVID-19 vaccines.

How allergens trigger itching: Finding points to new targets for allergy drug development
A key step in the immune system's response to allergens has been uncovered by researchers at Massachusetts General Hospital. They have shown that a neuropeptide called Substance P is released by certain neurons in the skin when they detect allergens, and that this substance is essential in the development of allergen-induced immune responses. This research could lead to the development of new and better methods to treat and prevent allergies. (2020-10-29)

International team of scientists discover link between genes and penicillin allergy using
Penicillin, a life-saving medicine, is the most common cause of drug allergy, with clinical manifestations ranging from temporary skin reactions to life-threatening systemic syndromes. Thus far, genetic factors have only been found for rare severe allergic reactions to penicillin. However, less is known about the genetics behind milder forms of penicillin hypersensitivity reactions that occur in a larger proportion of the population. (2020-09-03)

Allergic reaction: How the immune system identifies nickel
The metal nickel is one of the most common triggers of allergic contact dermatitis in humans. This skin inflammation results from a gradual immune reaction in allergic people, e.g. if the skin repeatedly comes into contact with nickel-containing jewellery, piercings or jeans buttons. BfR scientists have gained new insights into how the body's defences react to nickel. Their results have been published in the journal ''Allergy''. (2020-08-31)

Fewer serious asthma events in Philadelphia area following COVID-19 stay-at-home orders
Philadelphia and its surrounding counties issued a series of ''stay-at-home'' orders on March 17, 2020 in an effort to curb the spread of COVID-19. In the months that followed, Children's Hospital of Philadelphia (CHOP) saw a marked decrease in healthcare visits for both outpatient and hospitalized asthma patients. New research from CHOP and the Hospital of the University of Pennsylvania suggests the cause may have been fewer rhinovirus infections due to masking, social distancing, and hygiene measures. (2020-08-20)

Experts question need to wait days between introducing new solid foods to infants
The current recommendations from the American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC) call for introducing to infants one single-ingredient food at a time and waiting three to five days to observe for food allergy before introducing another new food. However, the long waiting period might be too long, given that food allergy becomes apparent within minutes to a few hours after eating a new food. (2020-08-17)

NIH-supported scientists demonstrate how genetic variations cause eczema
New research supported by the National Institutes of Health delineates how two relatively common variations in a gene called KIF3A are responsible for an impaired skin barrier that allows increased water loss from the skin, promoting the development of atopic dermatitis, commonly known as eczema. This finding could lead to genetic tests that empower parents and physicians to take steps to potentially protect vulnerable infants from developing atopic dermatitis and additional allergic diseases. (2020-08-14)

Gene variants help explain connection between skin disorder and food allergy risk
Two common variants in the KIF3A gene increase the risk of young children having a dysfunctional skin barrier and developing the skin condition atopic dermatitis, according to study led by scientists at Cincinnati Children's. (2020-08-14)

Therapy helps children with food allergies manage severe anxiety
Children's Hospital of Philadelphia (CHOP) has launched the Food Allergy Bravery (FAB) Clinic to help children with a phobia of anaphylaxis. This revolutionary clinic, housed within the Food Allergy Center, is the first in the world to bring together psychologists and food allergy experts to treat food allergic children with severe phobia of anaphylaxis.
