Histamine is a low-molecular-weight monoamine that binds to four different G-protein-coupled receptors, and has recently been demonstrated to regulate several essential events in the immune response. The histamine receptor type 2 (HR2) is coupled to adenylate cyclase and studies in different species and several human cells have demonstrated that inhibition of characteristic features of the cells by primarily cAMP formation dominates in HR2-dependent effects of histamine.

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.

Allergic rhinitis is a very common problem associated with poor quality of life, reductions in social and work activities and poor interpersonal relationships. The main goal of the management of allergic rhinitis is to improve the quality of life. Immunotherapy is a specific therapy for allergic rhinitis and several reports have documented the safety and efficacy of this treatment . Safety has been a key issue in immunotherapy and various modalities are being investigated to make allergy immunotherapy more tolerable and safe to administer. (more…)

Acute phase proteins are plasma proteins, the synthesis and the circulating concentrations of which are adaptively regulated in response to most forms of acute inflammation, infection and tissue injury. The name arises from the fact that the first such protein, C-reactive protein (CRP), was originally discovered in serum sickness of patients in the acute phase of pneumococcal pneumonia. (more…)

The food eating challenges materials used at different centers vary considerably. Some centers use freeze-dried foods, some use concentrated foods masked in other foods or capsules, and some use freshly prepared foods. This study aimed to develop and validate a number of recipes for Double Blind Placebo Control Food Challenges in Children. Common allergenic foods, cow’s milk, egg, soy, peanut, hazelnut and wheat were used where possible in their usual edible form. (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.

Airway hyper-responsiveness in asthma may involve smooth muscle growth, a manifestation of airway remodelling. The involvement of inflammatory cells in the induction of airway smooth muscle growth was studied in vivo and ex vivo in a brown Norway rat model of asthma. Transfer of CD4 + T lymphocytes from ovalbuminsensitized animals induced an increase in airway smooth muscle mass in naive animals upon repeated ovalbumin challenge. Ex vivo, coculture of antigen-stimulated CD4 + T cells and airway smooth muscle cells led to myocyte proliferation and prolonged T-cell survival. (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…)
