Anaphylactic shock or anaphylaxis is a severe and sometimes life-threatening immune system reaction to an antigen that a person has been previously exposed to. The reaction may include itchy skin, edema, collapsed blood vessels, fainting, difficulty in breathing, and death.
Most of the U.S. blood supply comes from about 5 million altruistic volunteers who donate blood regularly. Frequent blood donation is known to result in iron deficiency in donors, which has led to concerns that the practice may not only diminish the quality of donated blood but also harm blood donors' health and quality of life.
Although allergies are widespread, their diagnosis is complex and, depending on the type of allergy, the prospects of success with therapy are not always clear.
The world's first feasibility study has found that drones can be used to deliver life-saving defibrillators to people with suspected cardiac arrest in the community. The research is presented at ESC Congress 2021 and published in the European Heart Journal.
Parents of children with food allergies face significant worry, severe anxiety and post-traumatic stress – according to new research from the University of East Anglia.
Almost immediately after the first mRNA-based COVID-19 vaccines were authorized for emergency use and were administered to individuals outside of clinical trials, reports of anaphylaxis--a life-threatening whole-body allergic reaction--raised widespread concerns among experts and the public.
Anaphylaxis is a systemic allergic reaction that can affect the skin, the gastrointestinal tract, the respiratory system and the cardiovascular system.
In order to fight pathogens, mast cells regulate inflammatory reactions of the immune system. Both mast cells and neutrophils are white blood cells and are critical for the body's immune defense.
Ultra-small nanomedicines of approximately 18 nm were fabricated by dynamic ion-pairing between Y-shaped block copolymers and nucleic acid drugs, such as siRNA and antisense drugs.
To mark Allergy Awareness Week (19-25 October), two leading allergy charities are urging parents and teachers to ‘Check It, Don’t Chance It’ to ensure pupils and young adults with allergies are safe in schools.
The number of people throughout the world who suffer from a fish allergy is constantly increasing. The collagen contained in fish is an important allergen for many sufferers but is present in insufficient quantities in most commercially available diagnostic tests based on aqueous extracts of allergen sources.
As the mother of a child with food allergies, Heather Sapp was well versed in reading labels and calling manufacturers to verify ingredients. For years, she kept her daughter's diet free of the peanuts and tree nuts that could kill her.
For someone with a food or drug allergy, the risk of life-threatening anaphylactic shock lurks around every corner. A new Northwestern Medicine study shows there might be a pill that can be taken proactively to prevent mild to life-threatening anaphylaxis, no matter the cause.
Many childhood food allergies could be due to eating junk food, according to a new study. Children with food allergies, and children who eat a lot of junk food, have increased body levels of molecules called advanced glycation end-products (AGEs).
Fish allergy is one of the most dangerous food allergies, as it is often associated with potentially life-threatening symptoms such as anaphylactic shock.
The most severe allergic reaction, anaphylaxis, is the result of an inappropriate immune reaction following the introduction of a usually harmless antigen into the body.
Researchers from the School of Immunology & Microbial Sciences and the Medical Research Council have developed a new test to diagnose peanut allergy.
Platelets play a much more important role in our immune system than previously thought, according to a study published by researchers from Université Laval and Centre hospitalier universitaire de Québec Research Center.
People who suffer from life-threatening peanut allergies may soon be able to cure their condition by wearing a skin patch, according to the findings of a phase 2 trial.
People are not the only ones suffering from the symptoms and problems of food intolerance and allergies.
Researchers have developed a novel platform to more accurately detect and identify the presence and severity of peanut allergies, without directly exposing patients to the allergen, according to a new study published in the journal Scientific Reports.
