The incidence of allergic diseases, like asthma, allergic rhinitis, and food allergy, is increasing in Westernized countries. This chapter discusses the importance of taking a careful and focused history and physical examination, as well as the laboratory studies that can be used to demonstrate the presence of allergic sensitization. Treatment for allergic disease is discussed, with an emphasis on new biologic therapies that have been developed. Finally, the chapter explores relatively new studies on the potential for interventions to prevent food allergy.  Allergy is defined as an untoward physiologic event mediated by immune mechanisms, usually involving the interaction between an allergen and the allergic antibody, immunoglobulin E (IgE). Allergic reactions typically occur due to exposure to either airborne allergens, foods, drugs, chemicals, or Hymenoptera (such as wasps, bees and fire ants). Allergies manifest in numerous ways, including allergic asthma, allergic rhinoconjunctivitis, urticaria, eczema, and in its most severe form, anaphylaxis.

Introduction Allergic rhinitis (AR) is one of the most common allergic diseases, which affects ~20% of the world's population. T-helper (Th) type 2 cells produce interleukin (IL) 4 and IL-13, and mediate allergic responses, and these cytokines have been extensively studied as key players in the atopic airway diseases. However, the involvement of Th17 cells and IL-17 in AR has not been clearly examined. Aim To reevaluate AR clinical severity with serum IL-17, whether IL-17 affects the disease alone or in contribution with the atopic predisposition. Patients and Methods During an 18-month period, 39 individuals were divided into three groups: A, (13 control), B (13 with mild-to-moderate AR), and C (13 with severe AR). Both group B and group C patients (26) were subjected to clinical examination and allergy skin testing, and to measurement of both total serum immunoglobulin E (IgE) and IL-17 levels. Eleven patients with AR then were exposed to 6 months of cluster immunotherapy, whereas the rest of the patients were not exposed. Results Revealed a significant elevation of serum IL-17 levels with an associated increase in serum IgE in the patients with AR compared with controls and revealed that the serum levels of both total serum IgE and IL-17 decreased significantly after cluster immunotherapy. Conclusion These preliminary results added new data about the use of injective immunotherapy as well as reported on the use of sublingual immunotherapy.

Background: Eosinophilic enteritis, also known as eosinophilic gastroenteritis, is a rare primary eosinophilic gastrointestinal disorder (EGID) of unknown etiology characterized by the presence of an intense eosinophilic infiltrate on histopathology of the intestinal mucosa. Key Messages: The etiology of eosinophilic enteritis remains obscure. There is growing evidence to support the role of aeroallergens and food allergens in the pathogenesis of this disorder as children and adults with EGIDs often have positive skin testing for food allergens and a familial history of allergic diseases. Moreover, significant progress has been made in elucidating that EGIDs involve mechanisms that fall between pure IgE-mediated and delayed Th2 type responses. Preclinical studies have identified a contributory role for the cytokine IL-5 and eotaxin chemokines, providing a rationale for specific disease therapy. Eosinophilic enteritis causes a wide array of gastrointestinal symptoms such as abdominal pain, diarrhea, nausea, vomiting, bloating or ascites, and its diagnosis requires a high degree of clinical likelihood given the nonspecific presentation and physical examination findings. The Klein classification arbitrarily divided patients with eosinophilic enteritis into those with predominantly mucosal, muscle layer or subserosal disease relying on the concept that clinical presentation is dependent on the predominant involved layer of the gastrointestinal tract. Main therapeutic options are represented by oral corticosteroids for a short period with good efficacy. Antihistaminic drugs and sodium cromoglycate have also been used to treat patients with eosinophilic enteritis. Conclusion: Eosinophilic enteritis is generally considered as a benign disease with no relapse, but half of the patients may present a more complex natural history characterized by unpredictable relapses and a chronic course.

The prevalence of allergic diseases in the population varies in different countries from 10 to 40%. Improving the quality of diagnosis, treatment and prevention of allergic diseases is an urgent public health problem. The article deals with the etiology, pathogenesis, clinical picture and diagnosis of allergic diseases. The main stages of allergy diagnosis include a number of specific and non-specific examination methods. In particular, the authors consider various methods of laboratory diagnostics, discuss the indications and contraindications, and the benefits and drawbacks of various diagnostic methods. Although skin testing conducted by an allergist is the gold standard for the diagnosis of allergies, it has several contraindications and limitations, in the presence of which it is possible to perform laboratory diagnostic methods in vitro. For laboratory tests, it is necessary to choose a laboratory that uses modern methods of the third generation with an accuracy of 0.1 kU/L to detect allergic reactions, starting with the first class of significance. However, despite the importance of laboratory diagnostic methods, the conclusion should be made only after comparing with the following: clinical picture, data of the allergic, pharmacolo gical and food history, results of instrumental studies and skin tests (in t he absence of contraindications to their use). KEYWORDS: atopy, allergy, laboratory diagnostics, immunochemiluminescence assay, skin test, atopic dermatitis, allergic rhinitis, bronchial asthma, dermato-pulmonary syndrome.

Background. The prevalence of various allergic diseases has increased worldwide in recent decades. Allergy diagnosis in children should be economically optimal and as sparing as possible, while ensuring the high quality of medical care. Objective. The aim of the study is to develop optimal algorithms for analysis of sensitization profile in children with allergy family history, or suspected allergy, or atopy phenotype. Methods. Complete examination of 153 children aged from 1 to 17 years 11 months was performed. Children were divided in 4 groups according to the presence and characteristics of complaints, the presence of allergic disease. Sensitization was determined via the “gold standard” of allergy diagnosis — the ImmunoCap method (Phadia, Sweden), and the results of skin testing. Results. 97 (63.4%) children have shown sensitization to various allergens. We have revealed seasonal manifestation of allergy in children to various allergens: Fagales in 89-92% of cases, grasses in 68-72% of cases, weeds in 39-57% of cases. Complaints of all-year manifestations of allergic rhinitis were revealed in 24% of cases to cat dandruff, complaints of coughing and/or bronchospasm — in 100% of cases to birch pollen and in 35% of cases to house dust. The sensitization analysis has revealed strong correlations with confirmed statistical significance between pollen allergen sensitization classes in groups of different plants. Conclusion. Optimal algorithms for sensitization diagnosis in children living in Moscow agglomeration were developed according to the obtained results and revealed correlations.
