The allergic march is a progression of naturally occurring symptoms whose nature changes with age. classic typically begins in infancy and manifests the form atopic dermatitis food allergy. As immune tolerance develops over time, these conditions may resolve by age 3–5 years; however, they evolve into rhinitis bronchial asthma. Traditional diagnostic assessments, such as skin prick testing or serum allergen-specific immunoglobulin E (sIgE) level testing, are conducted to introduce effective treatment. Recent years saw emergence precision allergy molecular diagnosis (PAMD@), which assesses sIgE against allergenic molecules. This new technology helps more accurately evaluate patient’s profile, create precise dietary specifications personalize immunotherapy. review presents possible predictions regarding means controlling it based on PAMD@ results.

Abstract Allergen immunotherapy is a cornerstone in the treatment of allergic children. The clinical efficiency relies on well‐defined immunologic mechanism promoting regulatory T cells and downplaying immune response induced by allergens. Clinical indications have been well documented for respiratory allergy presence rhinitis and/or asthma, to pollens dust mites. Patients who had an anaphylactic reaction hymenoptera venom are also good candidates allergen immunotherapy. Administration currently mostly either subcutaneous injections or sublingual administration. Both methods extensively studied pros cons. Specifically children, choice method administration according patient's profile important. Although widely used, there need improvement. More particularly, biomarkers prediction success treatments needed. strength may be boosted use better adjuvants. Finally, novel formulations might more efficient improve adherence treatment.

Abstract

Precision allergy molecular diagnostic applications (PAMD@) is increasingly entering routine care. Currently, more than 130 allergenic molecules from 50 sources are commercially available for in vitro specific immunoglobulin E (sIgE) testing. Since the last publication of this consensus document, a great deal new information has become regarding topic, with over 100 publications in year alone. It thus seems quite reasonable to publish an update. imperative that clinicians and immunologists specifically trained allergology keep abreast rapidly evolving evidence PAMD@. PAMD@ may initially appear complex interpret; however, increasing experience, gained provides relevant allergist. This especially true food allergy, Hymenoptera selection allergen immunotherapy. Nevertheless, all sIgE tests, including PAMD@, should be evaluated within framework patient's clinical history, because sensitization does not necessarily imply allergies.

Allergen-specific immunotherapy (AIT) is an allergen-specific form of treatment for patients suffering from immunoglobulin E (IgE)-associated allergy; the most common and important immunologically mediated hypersensitivity disease. AIT based on administration disease-causing allergen with goal to induce a protective immunity consisting blocking IgG antibodies alterations cellular immune response so that patient can tolerate contact. Major advantages over all other existing treatments allergy are induces long-lasting protection prevents progression disease severe manifestations. cost effective because it uses patient´s own system potentially be used as preventive treatment. However, broad application limited by mainly technical issues such quality preparations risk inducing side effects which results in extremely cumbersome schedules reducing compliance. In this article we review progress made its beginning provide overview state art, needs further development, possible solutions available through molecular allergology. Finally, consider visions development towards prophylactic application.

House dust mite (HDM) allergy belongs to the most important allergies and affects approximately 65–130 million people worldwide. Additionally, untreated HDM may lead development of severe disease manifestations such as atopic dermatitis or asthma. Diagnosis immunotherapy allergic patients are well established but often hampered by use extracts that bad quality lack allergens. The individual allergens seems be a promising alternative natural allergen extracts, since they represent well-defined components can easily produced quantified. However, thorough characterization is required determine their clinical relevance identify those for correct diagnosis successful immunotherapy. This review gives an update on benefits patients.

More than 30 years ago, the first molecular structures of allergens were elucidated and defined recombinant became available. We review state art regarding AIT with goal to understand why progress in this field has been slow, although there is huge potential for treatment allergen-specific prevention.On basis allergen structures, several strategies have developed advanced into clinical evaluation. In trials, promising results obtained synthetic derivatives inducing IgG antibodies, which interfered recognition by IgE whereas efficacy could not yet be demonstrated approaches targeting only T-cell responses. Available data suggest that many advantages over extract-based AIT.Clinical studies indicate allergen-based vaccines, are superior existing can respiratory, food venom allergy. Allergen-specific preventive based on vaccine induction tolerance horizon hold promise allergy prevented. However, limited lack resources needed studies, necessary development these innovative strategies.

A large number of allergens have been discovered but we know little about their potential to induce inflammation (allergenic activity) and symptoms. Nowadays, the clinical importance is determined by frequency intensity IgE antibody binding (allergenicity). This a rather limited parameter considering development experimental allergology in last 20 years criteria that support personalized medicine. Now it known some allergens, addition properties, can through non mediated pathways, which increase allergenic activity. There are several ways evaluate activity, among them provocation tests, demonstration non-IgE pathways inflammation, case control studies IgE-binding frequencies, animal models respiratory allergy. In this review explored current status basic research on activity indoor confirm that, for most them, important property has not investigated.

Despite more than 30 HDM-derived allergens having been identified date, specific therapeutic approaches do not yet take into account the local sensitization profiles patients.
