Food Anaphylaxis

Introduction. Anaphylaxis is a systemic potentially life-threatening hypersensitivity reaction featuring the rapid onset, manifestations of the respiratory tract and/or hemodynamics and usually, but not always, accompanied by changes in the skin and mucous membranes [1]. The cause of developing an acute generalized reaction in food anaphylaxis may be the minimum culprit product amount that has entered the patient's body through the mouth or through the skin/mucous membranes. Patients like these are, as a rule, first seen by a paediatrician, a related specialist, or a paramedic. Since the doctors often consider the symptoms of foodborne anaphylaxis separately, the latter does not cause proper suspicion: angioedema and/or acute urticaria accompanying rhinorrhea, acute bronchospasm or laryngitis developed extremely quickly or immediately after contact with an allergen.The aim of the work was to acquaint paediatricians and doctors of related specialties with the food anaphylaxis symptoms, to justify the need for an allergologist-immunologist to consult these patients in order to resolve the issue of required component-resolved diagnosis of allergy and development of an individual elimination diet, taking into account the patient's sensitization profile.Materials and methods. Clinical observation of a child (boy, age — 12 months) with symptoms of atopic dermatitis and episodes of food anaphylaxis in the anamnesis; general clinical examination and allergological examination of the patient by component allergodiagnostics were performed.Results. Sensitization to ovalbumin (Gald 2 -16.60 kU/l) and ovomucoid (Gald 1-9.01 kU/l) was established. The detected sensitization is a predictor of severe systemic allergic reactions to eggs.Discussion. Component diagnostics performed as prescribed by an allergologist not only confirms the causative allergen, but also evaluates the risks of developing acute reactions if the allergen is accidentally introduced to the child and the timing of the patient's tolerance formation. This sensitization will cause sudden systemic allergic reactions for years to come.Conclusion. It is important for a specialist to timely suspect food anaphylaxis, differentiate it from other emergency and urgent conditions, and give the patient the correct recommendations on the need for consultation with an allergologist-immunologist. Only a thoughtful, comprehensive medical approach to each acute condition in a child will significantly reduce the risk of repeated episodes of food anaphylaxis.

Allergen Labeling

Food allergens are the substances present in food that cause food allergy. Human body reactions to food allergens range from mild to severe life threatening anaphylactic shock. At least seventy different foods have been reported to cause allergic reactions and several other foods have been identified which have the potential to provoke allergic reactions. Majority of the identified food allergens are proteins. The Food Allergen Labeling and Consumer Protection Act (FALCPA) identifies eight major food groups i.e. milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans as major allergy causing foods. These eight foods are believed to account for 90 per cent of food allergies and are responsible for most serious reactions to foods. Several studies have been done which identify the major allergens in various foods. The present paper attempts to review the major allergens present in various food.

Childhood food allergies are a growing public health problem. Once the offending food allergens have been identified, a strict elimination diet is necessary in treatment or prevention of most of the allergic reactions. Accidental food ingestion can lead to severe anaphylaxis. Food- derived substances can be used in medications at various stages of the manufacturing process. In this review, the possible roles of medications which may contain egg, red meat, gelatin, and fish allergens on allergic reactions in children with food allergy were evaluated.

History Of

Anaphylaxis is an acute life-threatening condition affecting several body systems. It might have a rapid onset and lead to a lethal outcome. The major provoking factors for the development of anaphylactic reactions in childhood are food allergens. High hypersensitivity to one food allergen can make it difficult for a family to find a substitution for an allergenic product. Food-induced anaphylactic reaction to quite a number of food allergens is a serious problem for both the physician and the family of an allergic child necessitating organization of appropriate and safe nutrition. In real life, the standard recommendation for the patient – to strictly follow the rules of the elimination diet with exclusion of the causative allergen and all cross-reactive allergens – often becomes unrealizable. There is a serious risk of developing new allergic reactions due to accidental intake of the triggering allergens because of incorrect food labelling by manufacturers. The objective of the work is to present a clinical case report that demonstrates the importance of performing allergy component testing (ImmunoCAP ISAC-112,) for identification of the full spectrum of allergens with subsequent assessment of allergenic molecules as triggering allergens and shows serious difficulties in the elaboration of recommendations on a personalised diet that should be adequate and safe for a child with a history of recurrent episodes of food-induced anaphylaxis. Key words: children, life-threatening reactions, allergy component testing, food labelling, food-induced anaphylaxis, food allergens

Food Anaphylaxis

The emergent health issue of food allergens presents an important challenge to the food industry. More than 170 foods have been reported in the scientific literature as causing allergic reactions. Clearly, it would be impossible to deal with the presence of trace amounts of all these in the context of food labeling. If the decision to classify major allergens is based solely on the knowledge and experience of allergists and food scientists in the field, without scientifically defined criteria, it is likely to lead to a proliferation of lists. Such practices may lead to an unnecessary elimination of foods containing important nutrients. This paper defines food allergy, food intolerance, and food anaphylaxis and identifies criteria for classifying food allergens associated with frequent allergic reactions. A practical list of food allergens that may result in potentially life-threatening allergic reactions is provided. A mechanism-based (i.e., immunoglobulin E mediated), acute life-threatening anaphylaxis that is standardized and measurable and reflects the severity of health risk is proposed as the principal inclusion criterion for food allergen labeling. Where available, prevalence in the population and threshold levels of allergens should be used as an additional guide to identify possible future labeling needs.

Анафилаксия - это тяжелая системная реакция гиперчувствительности, которая характеризуется быстрым началом и жизнеугрожающими проблемами со стороны дыхательных путей и кровообращения. В настоящей статье описан клинический случай развития у трехлетнего ребенка поливалентной аллергии с повторными эпизодами пищевой анафилаксии, родившегося и постоянно проживающего в средней полосе России, но имеющего необычный для жителя Урала профиль сенсибилизации. Клинический случай подробно описан с целью продемонстрировать этапы жизни ребенка, на которых, вероятно, сначала формировалась сенсибилизация, а в дальнейшем возникала манифестация клинических симптомов. Определение профиля сенсибилизации с использованием методов компонентной аллергодиагностики (ISAC, ImmunoCAP) показало, что мальчик сенсибилизирован к большому количеству пищевых аллергенов, в том числе к молочным и яичным протеинам белкам хранения арахиса, сои, фундука и кунжута протеинам, относящимся к nsLTP-белкам. Полученные результаты позволили распознать и дифференцировать истинную IgE-опосредованную сенсибилизацию, предложить оптимальную терапевтическую тактику и подобрать элиминационную диету. Применение методов молекулярной аллергодиагностики оказывается полезным в клинической практике в случае ведения пациентов, имеющих поливалентную сенсибилизацию и страдающих, по данным анамнеза, тяжелыми аллергическими реакциями.Anaphylaxis is a severe systemic hypersensitivity reaction that is characterized by rapid onset and life-threatening respiratory and blood circulation problems. We present to your attention a clinical case of the polyvalent allergy development in a three-year-old child with repeated episodes of food anaphylaxis. The child was born and he constantly lives in central Russia, but has a profile of sensitization unusual for a Ural resident. The clinical case is described in detail in order to demonstrate the stages of a childs life, on which sensitization was likely to be first formed, and later the manifestation of clinical symptoms arose. Determination of the sensitization profile by means of the component allergy diagnostics methods (ISAC, ImmunoCAP) showed that the boy is sensitized to a large number of food allergens, including milk and egg proteins storage proteins for peanuts, soy, hazelnuts and sesame proteins related to the nsLTP-proteins. The obtained results made it possible to recognize and differentiate true IgE-mediated sensitization, to propose the optimal therapeutic tactics and to select an elimination diet. Application of molecular allergy diagnostic methods is useful in clinical practice in case of patients with multivalent sensitization and a history of severe allergic reactions.

Adolescents And Adults

Four to eight percent of the population are estimated to be food-allergic. Most food allergies in adolescents and adults are acquired on the basis of cross-reaction to pollen allergens. Theses allergens are ubiquitous in the plant kingdom. Therefore pollen-allergic patients might acquire a multitude of different plant food allergies, and even react to novel foods to which they have never previously been exposed. A curative therapy for food allergy does not yet exist. Food-allergic patients have to rely on strict avoidance diets, The widespread use of industrially processed foods poses a general problem for food-allergic patients. Although the most frequent allergens must be declared openly in the list of ingredients, involuntary contamination with allergy-provoking compounds can occur. The precautionary labelling “may contain” is sometimes applied even if the chance of contamination is very low; on the other hand, foods not declared to contain possible traces of allergenic components may actually contain relevant amounts of allergenic proteins. Switzerland is the only country in Europe with legal regulations on contamination by allergenic food; however, the allowance of 1 g/kg is too high to protect a relevant proportion of food-allergic individuals.

Immunohistochemical Techniques

Anaphylaxis is a life-threatening or fatal clinical emergency characterized by rapid onset, and death may be sudden. The margin of certainty about the diagnosis of anaphylactic death is not well established. The application of immunohistochemical techniques combined with the evaluation of blood tryptase concentrations opened up a new field of investigation into anaphylactic death. The present study investigated eleven autopsy cases of anaphylactic death, carried out between 2005 and 2017, by the Departments of Forensic Pathology of the Universities of Foggia and Catania (Italy). An analysis of the medical records was carried out in all autopsies. Seven autopsies were carried out on males and four on females. Of the eleven cases, one showed a history of asthma, one of food ingestion, two of oral administration of medications, six did not refer any allergy history, and one subject was unknown. All cases (100%) showed pulmonary congestion and edema; 7/11 (64%) of the cases had pharyngeal/laryngeal edema and mucus plugging in the airway; only one case (9%) had a skin reaction that was found during external examination. Serum tryptase concentration was measured in ten cases, and the mean value was 133.5 µg/L ± 177.9. The immunohistochemical examination using an anti-tryptase antibody on samples from the lungs, pharynx/larynx, and skin site of medication injection showed that all cases (100%) were strongly immunopositive for anti-tryptase antibody staining on lung samples; three cases (30%) were strongly immunopositive for anti-tryptase antibody staining on pharyngeal/laryngeal samples; and eight cases (80%) were strongly immunopositive for anti-tryptase antibody staining on skin samples. We conclude that a typical clinical history, blood tryptase level >40 µg/L, and strongly positive anti-tryptase antibody staining in the immunohistochemical investigation may represent reliable parameters in the determination of anaphylactic death with the accuracy needed for forensic purposes.

Congenital factor XIII (FXIII) deficiency is a rare, autosomal-recessive disorder, with most patients having an A-subunit (FXIII-A) deficiency. Patients experience life-threatening bleeds, impaired wound healing, and spontaneous abortions. In many countries, only plasma or cryoprecipitate treatments are available, but these carry a risk for allergic reactions and infection with blood-borne pathogens. The present study was a multinational, open-label, single-arm, phase 3 prophylaxis trial evaluating the efficacy and safety of a novel recombinant FXIII (rFXIII) in congenital FXIII-A subunit deficiency. Forty-one patients ≥ 6 years of age (mean, 26.4; range, 7-60) with congenital FXIII-A subunit deficiency were enrolled. Throughout the rFXIII prophylaxis, only 5 bleeding episodes (all trauma induced) in 4 patients were treated with FXIII-containing products. The crude mean bleeding rate was significantly lower than the historic bleeding rate (0.138 vs 2.91 bleeds/patient/year, respectively) for on-demand treatment. Transient, non-neutralizing, low-titer anti-rFXIII Abs developed in 4 patients, none of whom experienced allergic reactions, any bleeds requiring treatment, or changes in FXIII pharmacokinetics during the trial or follow-up. These non-neutralizing Abs declined below detection limits in all 4 patients despite further exposure to rFXIII or other FXIII-containing products. We conclude that rFXIII is safe and effective in preventing bleeding episodes in patients with congenital FXIII-A subunit deficiency. This study is registered at http://www..clinicaltrials.gov as number NCT00713648.
