Allergen-specific immunotherapy is highly effective in the treatment of IgE-mediated allergy diseases such as rhinitis, conjunctivitis, asthma, and venom allergy hypersensitivity. It is the only treatment that leads to lifelong tolerance against previously disease-causing allergens due to restoration of the normal immunity. (more…)

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.

Diagnosis of food hypersensitivity is a clinical challenge and the only current definitive test is the Double Blind Placebo-Controlled Food Challenges. Although the Double Blind Placebo-Controlled Food Challenges is the current gold standard, it is difficult to perform and is very time-consuming. Hence, researchers are continually evaluating new tests and assessing the value of the available serum tests. (more…)

The potency of an allergen vaccine is the total allergen activity (that is, the sum of the contribution to allergenic activity from any individual IgE molecule specific for any t-cell epitopes on any molecule in the allergen vaccine). It follows that potency measures always will depend on the serum pool or patient panel selected as well as the methodology used. Methods used for the assessment of allergen vaccine potency may be divided into in vitro or in vivo techniques. (more…)

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.

Asthma and allergic diseases are common in both children and adults. Their development depends on an interaction between asthma genetic and asthma environmental risk factors. Genetic manipulation in multi factorial diseases such as asthma is not feasible in the foreseeable future. However, theoretically, environmental exposures can be controlled in an attempt to stem the rising prevalence of these diseases (primary prevention). Environmental exposures may also influence the frequency of symptoms and the requirement for medication in those with established disease. (more…)

Systemic allergic reactions are a relatively common clinical emergency. In their mildest form, they may just manifest as systemic cutaneous reactions with pruritis, allergy urticaria and angioedema. In more severe cases there are cardiorespiratory symptoms such as stridor, wheeze, difficulty in breathing or hypotension. Anaphylaxis has been defined as a ‘severe, life-threatening generalized or systemic hypersensitivity reaction’. The prevalence of systemic allergic reactions is unclear because of the lack of a clear, consistent definition and large prospective population studies. (more…)

Atopic dermatitis is a chronic inflammatory condition of the skin which usually starts in infancy. It is sometimes called ‘atopic eczema’ or even simply ‘eczema’. Recently, the term ‘atopic eczema dermatitis syndrome’ or eczema symptoms or infantile eczema has also been proposed to indicate the varied nature of this disease. The diagnosis is based on clinical features of a chronic itchy dermatitis with typical morphology and distribution and a relapsing and remitting course. (more…)

An allergic patient’s history may point the clinician’s assessment to a specific area or organ system during allergy testing. In general, physical examination may be standard; shortage of findings isn’t going to rule out allergy.
Essential indicators are a starting point in any physical examination of allergic patients. Respiratory rate is essential as well, but hyperventilation is more a representation of minute ventilation (respiratory rate × tidal volume) than respiratory rate on it’s own. (more…)
