Roflumilast is an oral, once-daily inhibitor of phosphodiesterase type 4 (PDE4) that prevents the breakdown of cyclic adenosine monophosphate (cAMP) levels, leading to inhibition of pro-inflammatory signalling. This study investigated the effects of repeated doses of 250 or 500 µg of roflumilast on airway asthma responses to allergen. (more…)

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…)

Being an immunological disease, the characteristics of allergy are those of specificity and memory. Regardless of whether the clinical manifestation is rhinoconjunctivitis, rhinitis, or asthma, the underlying immunological response disorder is based on the adverse reactions of cells in the immune system upon contact with allergens. These cells are specific for epitopes that are structural parts of allergens present in the allergenic source material. Two types of cells (i.e., T cells and B-cells) produce receptor molecules (i.e., T-cell receptors and immunoglobulin [IgE] antibodies) that, through high-affinity interactions with the allergen, efficiently catalyze the presence of even minute amounts of allergens into clinical symptoms, the extreme consequence of which may be life-threatening to the patient.

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.

A cross-sectional, descriptive, questionnaire-based survey was conducted in schools in Toulouse, France, to determine the prevalence of food allergies among children in school. The first goal of the survey was to estimate the prevalence of food allergies. The second goal was to determine the main characteristics of the allergies. The questionnaires (3500) were distributed in 150 classes in eight schools. The return rate was 77.6% (2716). (more…)

Patients (and many doctors) frequently use the term ‘allergy’ when referring to any adverse drug reaction, even one that has no features of an IgE-mediated allergy response. However, IgE-mediated allergy explains only about 10% of all adverse reactions to antigen antibody reactions from antibiotics. Patients who have experienced unexplained symptoms during treatment with two or more antibiotics are often said to have ‘multiple antibiotic allergy’; using this definition, the description can be applied to one patient in every 22.

Gastrointestinal allergy can be classified according to the triggering antigen, the mechanism of immune reaction, or the anatomic site of reaction.
Gastrointestinal allergy may be triggered by food components (e.g. food proteins or glycoproteins), and by other antigen antibody reaction to (e.g. bacterial disease, viral, fungal, and worm antigen), drugs and chemicals, (more…)

B cells
The main function of B cells is to produce antibodies. Antibodies are complex molecules produced by the immune system in response to antigens. As mentioned previously, antigens are foreign proteins or glycoproteins (a sugar linked to a protein) that trigger the immune response. Every living cell produces several different proteins, each unique to its own cell type and species. The antibody produced against the antigen is entirely specific to that antigen. (more…)

Specific immunotherapy has been widely used to treat allergic rhinitis symptoms. As with any other form of specific immunotherapy, careful patient selection is crucial. The diagnosis of allergic rhinitis needs to be secure, especially in those with perennial symptoms, and should be based on a careful clinical history supported by documentation of IgE-mediated sensitivity by skin prick test or blood tests.
