This study compared the diagnostic value of intradermal tests and patch tests in 20 patients with non-immediate reactions to penicillin (none had IgE antibodies to benzylpenicillin or amoxicillin detectable using a commercial RAST [radioallergosorbent test] method), using 30 patients tolerant to penicillin as controls. Intradermal tests assessed reactivity to injection of major and minor determinants of benzylpenicillin, amoxicillin and ampicillin. Allergy patch testing involved the same hapten solutions used for intradermal testing, either embedded in a patch disk or mixed with petrolatum. (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.

Allergy skin testing is probably the most susceptible and practical way to monitor for existing allergy sensitivity. Biological extracts of aeroallergens such as trees, dust mites, weeds, cockroaches, molds, and animal danders are offered for allergy testing. The most common and approved way to test is by putting a drop of antigen on the surface area of the patient’s skin and scratching or skin prick test with a lancet or sharp object. The most essential ancillary test to confirm the diagnosis of allergy is the skin test, which is the gold standard in this respect. The skin test final results must be viewed in light of the history to decide the importance of a positive test. (more…)

The most crucial element in the assessment process of a possible allergic problem is patient’s allergy history. An allergy history is made up of a chief problem, resolve of seasonality or diurnal variation of symptoms, detection of triggers, occupational asthma exposure, and reaction to medicines, family history, and some other relevant medical history. An allergy history looks for to define the patient’s chief complaint(s) and concentrates on the details with regards to those complaints. There is a lexicon typical to patients with allergy complaints. Sinus dizziness strain and headaches are often cited as symptoms. The history taker should be attuned to the patient’s viewpoint as a possible allergy sufferer. Exactly where and when does the symptom happen? Or is it happened during sleep? (more…)

One of the popular allergy testing besides food allergy testing is skin allergy testing. Allergy patch test is the most common allergy skin test diagnosis. It first description of a patch test performed by Jadassohn J. in 1895. Allergy patch test has been used for the diagnosis of type IV reactions, particularly exanthematous drug eruptions and drug allergy contact dermatitis. They are described in detail in the section of infantile eczema. But the immediate reactions, such as contact allergic urticaria, red, open patch test has alleged importance. (more…)

Allergen immunotherapy has proven to be effective in the management of allergic disease and is the only treatment that is able to modify the natural course of the disease. Its wider applicability for the treatment of allergic disease has, in part, been limited by its perceived safety profile. This study follows up previous fatal reaction surveys undertaken in the USA for the periods 1959–1984 and 1985–1989. (more…)

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…)

The diagnostic approach to allergic food reactions comprises three steps. The first step includes the medical allergy history, physical examination, and family allergy background. On the basis of symptoms and timing of the reaction, the physician attempts to identify the suspected food and to determine whether the reaction is likely to involve an immunologic mechanism. This first step is absolutely necessary to decide on the subsequent diagnostic tests to be performed. The second step includes allergy skin tests and in vitro assays, which can confirm a sensitization to the food. (more…)
