Allergic Disorders

Non-IgE-mediated gastrointestinal food allergy (non-IgE-GI-FA) is the name given to a series of pathologies whose main entities are food protein-induced allergic proctocolitis (FPIAP), food protein-induced enteropathy (FPE), and food protein-induced enterocolitis syndrome (FPIES). These are more uncommon than IgE-mediated food allergies, their mechanisms remain largely unknown, and their diagnosis is mainly done by clinical history, due to the lack of specific biomarkers. In this review, we present the latest advances found in the literature about clinical aspects, the current diagnosis, and treatment options of non-IgE-GI-FAs. We discuss the use of animal models, the analysis of gut microbiota, omics techniques, and fecal proteins with a focus on understanding the pathophysiological mechanisms of these pathologies and obtaining possible diagnostic and/or prognostic biomarkers. Finally, we discuss the unmet needs that researchers should tackle to advance in the knowledge of these barely explored pathologies.

Eosinophilic Disorders

Food allergies, defined as an immune response to food proteins, affect as many as 8% of young children and 2% of adults in western countries, and their prevalence appears to be rising like all allergic diseases. In addition to well-recognized urticaria and anaphylaxis triggered by IgE antibody– mediated immune responses, there is an increasing recognition of cell-mediated disorders, such as eosinophilic esophagitis and food protein–induced enterocolitis. Non-IgE-Mediated gastrointestinal food allergies are a heterogeneous group of food allergies in which there is an immune reaction against food but the primary pathogenesis is not a production of IgE and activation of mast cells and basophils. Those diseases tend to affect mainly the gastrointestinal tract and can present as acute (FPIES) or chronic reaction, such as Eosinophilic Esophagitis (EoE), Food Protein-Induced Allergic Proctocolitis (FPIAP). The role of food allergy in Non-EoE gastrointestinal Eosinophilic disorders (Non- EoE EGID) is poorly understood. In some diseases like EoE, T cell seems to play a major role in initiating the immunological reaction against food, however, in FPIES and FPIAP, the mechanism of sensitization is not clear. Diagnosis requires food challenges and/or endoscopies in most of the patients, as there are no validated biomarkers that can be used for monitoring or diagnosis of Non-IgE mediated food allergies. The treatment of Non-IgE food allergy is dependent on diet (FPIES, and EoE) and/or use of drugs (i.e. steroids, PPI) in EoE and Non-EoE EGID. Non-IgE mediated food allergies are being being investigated.

Abstrak: Prevalensi alergi makanan makin meningkat di seluruh dunia dan mengenai semua usia. Keparahan dan kompleksitas penyakit juga meningkat terlebih pada populasi anak. Terdapat beberapa jenis reaksi alergi yang dibahas: immunoglobulin E (IgE) mediated allergies and anaphylaxis, food triggered atopic dermatitis, eosinophilic esophagitis, dan non IgE mediated gastrointestinal food allergic disorders seperti food protein induced enterocolitis syndrome (FPIEs). Tes alergi, baik melalui kulit maupun IgE yang telah dikerjakan sekian lama masih dibebani dengan hasil positif palsu dan negatif palsu yang bermakna dengan manfaat terbatas pada beberapa alergi makanan. Selain menghindari, tidak terdapat terapi yang ampuh untuk alergi makanan. Berbagai imunoterapi telah dipelajari melalui jalur, subkutan, epikutan, oral dan sublingual yang hanya menghasilkan desensitisasi sementara dan dibebani dengan berbagai isu mengenai keamanannya. Agen biologik yang menghambat sitokin/interleukin (IL) dan molekul pada reaksi alergi makanan tampaknya merupakan pilihan yang menjanjikan. Anti IgE telah dipergunakan pada asma dan urtikaria kronis. Anti IL-4 dan IL-13 yang menghambat produksi IgE diindikasikan untuk dermatitis atopik. Anti eosinofil anti IL-5 berhasil menurunkan eksaserbasi asma. Berbagai agen biologik telah dipelajari untuk berbagai kondisi alergik dan imunologik, tetapi efektivitas dan kepraktisan terapi yang mahal ini untuk alergi makanan masih menjadi tanda tanya.Kata kunci: alergi makanan, reaksi alergi, terapi alergi makananAbstract: Food allergies have been increasing in prevalence for years affecting all ages. Disease severity and complexity have also increased, especially in the pediatric population. There are several types of reactions including: immunoglobulin-E (IgE) mediated allergies and anaphylaxis, food-triggered atopic dermatitis, eosinophilic esophagitis, and non IgE mediated gastrointestinal food allergic disorders such as FPIEs. Though allergy testing has been around for years, both skin and IgE testing are burdened by significant false positives and negatives, and are only useful in some food allergies. Avoidance is the sole therapy for food allergy. A variety of immunotherapies have been studied; subcutaneous, epicutaneous, oral, and sublingual. At best they only produce a temporary state of desensitization and have many safety issues. Examples of biologicals which block critical cytokines/interleukins (IL) in allergic conditions are Anti IgE, anti IL-4 and IL-13, and Anti eosinophils, Anti IL-5. Other biologicals are being studied for allergic conditions, but whether these expensive future treatments will be proven effective and practical in food allergy is unknown.Keywords: food allergy, allergic reaction, food allergy therapy

Allergic Disorders

Gastrointestinal food allergies are a spectrum of disorders that result from adverse immune responses to dietary antigens. The named disorders include immediate gastrointestinal hypersensitivity (anaphylaxis), oral allergy syndrome, allergic eosinophilic esophagitis, gastritis, and gastroenterocolitis; dietary protein enterocolitis, proctitis, and enteropathy; and celiac disease. Additional disorders sometimes attributed to food allergy include colic, gastroesophageal reflux, and constipation. The pediatrician faces several challenges in dealing with these disorders because diagnosis requires differentiating allergic disorders from many other causes of similar symptoms, and therapy requires identification of causal foods, application of therapeutic diets and/or medications, and monitoring for resolution of these disorders. This review catalogs the spectrum of gastrointestinal food allergies that affect children and provides a framework for a rational approach to diagnosis and management.

Conclusive Diagnosis

Non-immunoglobulin E-mediated gastrointestinal food allergic disorders (non-IgE-GI-FA) include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE) and food protein-induced allergic proctocolitis (FPIAP), which present with symptoms of variable severity, affecting the gastrointestinal tract in response to specific dietary antigens. The diagnosis of non-IgE-GI-FA is made clinically, and relies on a constellation of typical symptoms that improve upon removal of the culprit food. When possible, food reintroduction should be attempted, with the documentation of symptoms relapse to establish a conclusive diagnosis. Management includes dietary avoidance, nutritional counselling, and supportive measures in the case of accidental exposure. The prognosis is generally favorable, with the majority of cases resolved before school age. Serial follow-up to establish whether the acquisition of tolerance has occurred is therefore essential in order to avoid unnecessary food restriction and potential consequent nutritional deficiencies. The purpose of this review is to delineate the distinctive clinical features of non-IgE-mediated food allergies presenting with gastrointestinal symptomatology, to summarize our current understanding of the pathogenesis driving these diseases, to discuss recent findings, and to address currents gaps in the knowledge, to guide future management opportunities.

Abstract The most common types of non-IgE-mediated food allergy are food protein-induced enterocolitis syndrome (FPIES) and food protein-induced allergic proctocolitis (FPIAP). FPIES presents with delayed refractory emesis, while FPIAP presents with hematochezia in otherwise healthy infants. Acute management of FPIES includes rehydration or ondansetron, or both. No acute management is required for FPIAP. Long-term management of both disorders includes avoidance of the trigger food. The prognosis for both conditions is a high rate of resolution within a few years’ time.

Allergic Disorders

Allergic disorders may be classified into four main categories of immunologic hypersensitivity reactions: type I, immediate or anaphylactic; type II, cytotoxic; type III, involving immune complexes; and type IV, delayed or cell mediated. Type I reactions are those most commonly encountered in clinical allergy. They may be well defined by skin testing, provided the patients to be tested are carefully selected and the tests are applied properly and interpreted critically. Major indications for direct skin testing are: (1) to separate atopic from nonatopic patients; (2) to help in identifying specific allergens in atopic persons; and (3) to reassess the allergic profile in patients receiving immunotherapy. Other indications for skin-testing, of more limited applicability, include: (1) screening for hypersensitivity to vaccines; (2) testing for reactivity to drugs (and particularly penicillin); (3) testing for immediate and delayed reactions in such conditions as bronchopulmonary aspergillosis; and (4) in evaluation of patients with reactions to insect stings. Skin-testing has limited usefulness in early infancy, in chronic urticaria, in the investigation of food allergies, in atopic dermatitis not accompanied by other manifestations of atopy, or in allergic reactions to drugs other than penicillin. A checklist to be consulted prior to performing or interpreting skin tests should include: (1) assurance of the potency of the extract used in testing; (2) knowledge of the nonspecific irritant properties of any extracts used for testing; (3) history of administration of antihistamine drugs or epinephrine prior to testing; and (4) the correlation of skin test results with clinical history. The help of a qualified allergist should be sought if: (1) skin test results are at variance with the historical data; or (2) systemic reactions are induced by skin testing; or (3) the patient fails to respond to the therapy dictated by the skin test results. Alternatives or supplements to skin-testing include RAST testing and measurement of histamine release from sensitized leukocytes. These have rendered passive transfer testing (PK or Prausnitz-Küstner) substantially obsolete. Direct allergy skin testing remains the most sensitive, most specific, and most reliable method presently available to the physician for investigation of IgE-mediated allergic disorders.
