Normally present at very low levels in plasma, antibodies of the immunoglobulin E (IgE) isotype were first discovered in 1967, decades after the description of IgA, IgG, and IM. IgE antibodies are produced primarily by plasma cells in mucosal-associated lymphoid tissue and their levels are uniformly elevated in patients suffering from atopic conditions like allergic rhinitis, asthma and atopic dermatitis. Production of allergen-specific IgE in atopic individuals is driven both by a genetic predisposition to the synthesis of this isotype as well as by environmental factors, including chronic allergen exposure.

Suspected drug allergy is not easy to investigate. In the UK, few centers have the necessary facilities and expertise, the evidence base of the available diagnostic tests is not robust, and their interpretation of drug allergy reaction is not straightforward. This has led many clinicians increasingly to rely on the patient’s recollection of previous response to individual allergies medicines when anticipating the likely tolerability of future exposure.

Families frequently do not use their self-injectable adrenaline device, even when their kids is experiencing a potentially life-threatening cardiorespiratory allergic reaction to a food allergen. Fatal food allergy anaphylaxis is rare but well recognized and the early use of intramuscular adrenaline may be life-saving. (more…)

At least a million Spanish suffer allergic reactions to food, some of them as common as milk, eggs, fruit or fish. Many of them are children who are constrained in their quality of life and opportunities to participate in activities as usual for other children and enjoy a family meal, eating at school, have a pizza or a bagel or even attend a children’s party. An accidental ingestion of a food to which you are allergic (which happens often due to lack of identification of many food allergy ingredients) can have serious consequences, from allergic urticaria to anaphylaxis symptoms.

Definitions of anaphylaxis vary considerably, impeding the comparison of different clinical studies. Different definitions of anaphylaxis have been developed as clinical descriptions of severe allergic reactions, different authors emphasizing different symptoms.
The author aimed to develop a simple clinical grading system and definition for anaphylaxis using clinical data. He retrospectively analyzed 1149 case records (median age 29 years) with systemic allergic reactions (30% venom allergy, 22% iatrogenic allergy, 18% food allergy) from an emergency department in Australia.
