Definition and Classification

The nomenclature of allergic and hypersensitivity diseases was established past the European Academy of Allergy and Clinical Immunology (EAACI) and the Earth Allergy Arrangement (WAO) in 2004 (ane). The definitions and concepts of allergic and hypersensitivity weather condition beyond the allergy customs accept often created misunderstanding (2). For an optimal clarification:

• the term "atopy" is used when individuals take an IgE sensitization as documented by IgE antibodies in serum or by a positive skin prick test;
• "hypersensitivity" is divers as "atmospheric condition clinically resembling allergy that cause objectively reproducible symptoms or signs, initiated by exposure to a divers stimulus at a dose tolerated by normal subjects", and
• "allergy" is defined "a hypersensitivity reaction initiated by proven or strongly suspected immunologic mechanisms".

Based on these definitions, a correct diagnosis of allergic disease must adhere to the following conditions:

a) Compatible clinical history; and
b) Positivity to in vivo and/or in vitro tests to prove underlying mechanism and etiology.

The tests alone cannot exist used considering many people are sensitized (positive results to in vivo and/or in vitro tests), but not allergic (no reactions).

Specifically for 'food allergy', this term is used when a causal relationship (ideally, with a specific immunological mechanism) has been defined. There are three wide groups of immune reactions: IgE-mediated, not-IgE-mediated and mixed. The IgE-mediated reactions are unremarkably divided into immediate-onset reactions (arising up to 2 hours from the nutrient ingestion) and firsthand plus late-stage (in which the immediate onset symptoms are followed by prolonged or ongoing symptoms). Non-IgE-mediated reactions, which are poorly defined both clinically and scientifically, are believed to be mostly T-cell-mediated. They are typically delayed in onset, and occur 4 to 28 hours subsequently ingestion of the offending food(s). Mixed IgE and non-IgE mediated reaction are conditions associated with nutrient allergy involving both IgE- and non-IgE-mediated mechanisms (three).

A series of adverse reactions to foods exercise not involve an immune response and are non considered nutrient allergies (4). These include metabolic disorders (for example, lactose and alcohol intolerance), responses to pharmacologically active nutrient components, as caffeine, theobromine in chocolate or tyramine in fermented cheeses, or toxic reactions. Toxic reactions to food tin occur in any patient, if a sufficient amount of the nutrient is ingested; they are due to toxins in the food, e.yard., to histamine in scombroid fish or bacterial toxins in food.

While sometimes these, and other presumed nutrient allergic reactions, are defined "food intolerances", this term should not exist used to define an allergic reaction (5). Host factors such equally lactase deficiency, which are associated with lactose intolerance, or idiosyncratic responses may exist responsible for other non-allergic reactions to foods.

Underlying Mechanisms of Food Allergy

Typical food allergies are IgE-mediated, but several reactions involve different immunologic mechanisms. These nutrient allergies are defined as non–IgE-mediated or mixed IgE- and not–IgE-mediated.

The symptoms of IgE-mediated, non-IgE–mediated, and mixed IgE- and non–IgE-mediated food allergy are presented in Table 1³. IgE-mediated symptoms develop inside minutes to i-2 hours of ingesting the food, not–IgE-mediated and mixed IgE- and non–IgE-mediated food allergies present with their symptoms several hours later the ingestion of the food.

All these manifestations derive from a failure to develop or a breakdown of food tolerance, resulting in excessive production of nutrient-specific IgE antibodies or in altered cellular events, leading to allergic reactions. Environmental influences and genetic factors of the host underlie the immunopathogenesis of food allergy and its manifestations. Some clinical studies have revised our agreement of the crusade of food allergy. For case, functional genetic variants in the IL-12 receptor b1, Toll-like receptor 9, and thymic stromal lymphopoietin genes and even IL-4 gene polymorphism have been associated with an increased adventure of food sensitization (6). In the hereafter, the elucidation of the factor-environment interactions will be crucial for understanding the food allergy pathogenesis. Microbiome, i.e., -omic, studies are an emerging field of interest to ascertain allergy pathogenesis and, in a non too distant future, the microbiome could offer novel therapeutic possibilities (7).

Epidemiology

Food allergy is described as an increasing illness over time. Information technology is generally accustomed that food allergy affects approximately 2.five% of the general population, but the spread of prevalence data is wide, ranging from 1% to 10%. Accurate determination of the prevalence is still i of the major issues with food allergy, because that many factors influence the reported prevalence of nutrient allergy. The varied factors include differing criteria for making food allergy diagnosis, study methodologies, geographic variation, ages, and dietary exposures to name a few. In European birth cohorts, the incidence ranges from two.xviii% (United Kingdom) to 0.07% (Hellenic republic) (8).

The near common foods, eaten separately or included as an ingredient, even in trace amounts (hidden nutrient), that elicit hypersensitivity reactions are milk, egg, wheat, fish, and nuts.

Despite the fact that up to 2.5% of newborn during the first years of life are diagnosed as allergic to cow'south milk, recent European prevalence information fix the prevalence of moo-cow's milk allergy (CMA) to 0.7% (9).

Within the EuroPrevall nascence cohort, the mean adjusted incidence of hen's egg allergy was i.23% (10), while the Australian Healthnuts study reports a prevalence of 9% (11).

The prevalence of peanut allergy among children in the United Kingdom, Northward America, and Australia has been reported doubled in 10 years and is approximately one.8%, 1.4%, and 3.0% respectively.

Fish allergy prevalence ranges from 0% to 7% and the prevalence of shellfish allergy from 0% to ten.3%, depending on the method used for diagnosis. The just written report using nutrient challenges reports a prevalence of fish allergy of 0% - 0.iii% and a prevalence of shellfish allergy ranging between 0% and 0.9%. Fish allergy seems more frequent in Asia (12) than in Western countries (thirteen).

Epidemiological studies reveal that among food-allergic infants, approximately 80% will reach tolerance by the fifth birthday, but 35% of them may eventually develop hypersensitivity to other foods. Those with the highest IgE levels, with the most serious clinical manifestations (anaphylaxis and asthma), and with the wider co-sensitizations are less probable to overgrowth their nutrient allergy. The natural history of food allergy also depends on the specific food sensitization, with children allergic to milk and egg displaying a better prognosis than those allergic to peanuts, tree nuts and fish(14).

Cantankerous-Reactivity and Nutrient Allergens

Component Resolved Diagnosis (CRD) elucidated the link between a severe allergy to pollen and the increase of oral allergy syndrome (OAS), do induced asthma and anaphylaxis when eating certain foods. Such reactions are due to cross-reactive allergens equally pathogenesis related (PR),  profilins, or lipid transfer proteins (LTP). These proteins are ubiquitous in pollens, plants, fruits and nutrient. Individuals sensitive to firm grit mites have been reported with oral allergy syndrome following ingestion of shellfish(15). Children with CMA may react to beef in up to 20% of cases, to goat's milk in 98%, and to ass milk in 20% of cases(xvi).

IgE-Mediated Food-Related Disorders

Skin Manifestations

Acute urticaria and angioedema are the most frequent manifestation of food allergy. The onset of symptoms may exist rapid, within minutes, following the ingestion of the offending food. Foods most often implicated include milk, fish, vegetables and fruits. In atopic dermatitis, also a frequent symptom of nutrient allergy, immediate reactions can be followed by late cutaneous reactions.

Gastrointestinal Tract

Symptoms caused by immediate sensitivity in the gastrointestinal tract typically develop within minutes to 2 hours of ingesting the offending nutrient. Symptoms tin can include lip, tongue and palatal pruritus and swelling, laryngeal oedema, nausea, abdominal cramping, airsickness and diarrhoea. Severe reactions tin consequence in well-nigh or all symptoms associated with anaphylaxis.

Oral allergy syndrome (OAS), a form of contact urticaria confined to the lips and oropharynx, about ordinarily occurs in pollen-allergic patients. Symptoms include oropharyngeal itching, with or without facial angioedema, and/or tingling of the lips, natural language, palate and throat.

Respiratory Reactions

Allergic rhinoconjunctivitis and asthma can occur post-obit food challenge testing, but respiratory symptoms from food allergy in the absence of pare or gastrointestinal manifestations are rare. When respiratory symptoms occur following food challenge, both early- and late-phase IgE-mediated mechanisms are probably involved.

Systemic reaction: Anaphylaxis

Anaphylaxis is an explosive systemic reaction. About fifty% of anaphylaxis reactions are due to food allergy. It occurs inside few minutes to hours after food ingestion(17). 90 per cent of patients experience peel (urticaria, angioedema) plus respiratory symptoms such as asthma, rhinitis or conjunctivitis; in 30% of the cases, they also develop gastrointestinal symptoms or hypotension, and shock and cardiac arrhythmias may occur. All of this is acquired past the massive release of mediators from mast cells and basophils.

A form of anaphylaxis associated to food is the practice-induced food-dependent anaphylaxis, occurring, generally, 2-4 hours subsequently ingestion of a nutrient to which the individual is allergic. Food or exercise alone volition not cause this reaction. Risk factors for food-induced anaphylaxis include asthma and previous allergic reactions to the causative food.

Table 1. Specific Food-Induced Allergic Conditions³

Non-IgE-Mediated Nutrient Allergic Disorders

Gastrointestinal

Food allergy is besides linked to manifestations of delayed hypersensitivity, partially IgE-mediated and partially non-IgE-mediated. Information technology is implicated in Eosinophilic Esophagitis, Eosinophilic gastritis and gastroenteritis, nutrient protein-induced enterocolitis syndrome, and allergic proctocolitis.

Food protein –induced enterocolitis syndrome (FPIES)

Primarily affects infants. In chronic forms, it presents as emesis, diarrhea, poor growth, and, in severe cases, with starvation and lethargy. In acute forms, or after re-administration of restricted foods, it may determine emesis, diarrhea, and hypotension, starting two hours following ingestion. Diarrhea may be bloody and may effect in aridity, especially in early infancy.  Information technology has been associated frequently to ingestion of  cow's milk, soy, oat, wheat, and/or rice. Skin prick test to the suspected foods are generally negative, but IgE-mediated food allergy may be associated with FPIES every bit sometimes the ii conditions co-exist or i class transforms into the some other. International consensus guidelines have been developed for FPIES.(18)

Food protein-induced allergic proctocolitis (FPIAP)

FPIAP is a benign transient condition, typically starting in the beginning few months of life with encarmine stools in well-appearing infants. Virtually 60% of cases occur in chest-fed babies, the residue in infants fed cow'southward milk or soy poly peptide-based formulas.

Rarely, dietary protein proctitis shows mild hypoalbuminaemia and peripheral eosinophilia. Bowel lesions are usually confined to distal large bowel; endoscopy reveals linear erosions and mucosal oedema with infiltration of eosinophils in the epithelium and lamina propria.

Food-induced pulmonary haemosiderosis (Heiner'due south Syndrome)

This very rare syndrome, affecting infants and immature children, is characterized past recurrent episodes of pneumonia associated with pulmonary infiltrates, haemosiderosis, gastrointestinal blood loss, fe deficiency, anaemia, failure to thrive. It is due to cow's milk(19); the immunologic mechanism is still unknown.

Mixed IgE and non-IgE reactions

Eczema

Although information technology is non, strictly speaking, an allergic affliction, at least ane-3rd of infants and young children with atopic eczema have IgE-mediated nutrient allergy. Egg allergy is the nearly mutual food hypersensitivity in children with eczema. Appropriate diagnosis of food allergy and elimination of the offending allergen leads to meaning clearing or comeback of eczematous lesions in many young children with eczema and food allergy. Food allergens may be triggers for some astute exacerbations (twenty).

Allergic eosinophilic oesophagitis (EoE).

This condition may present in children with a variety of nonspecific symptoms, e.g., feeding difficulty, nausea, vomiting, heartburn, and failure to thrive. Teenagers and adults are more than likely to nowadays with dysphagia and episodes of food impaction.

Eighty per centum of patients with eosinophilic esophagitis have symptoms similar to gastroesophageal reflux, which are refractory to anti-reflux therapy. In the case of infants, the vomitus oft contains stringy mucus (like to egg albumin). Patients may also present with nutrient refusal, dysphagia, food impaction or abdominal pain. Nutrient induced IgE-mediated allergy has been implicated in the pathogenesis in some patients. In eosinophilic esophagitis at that place may exist years of unrecognized babyhood subclinical disease or "silent" chronic inflammation before the diagnosis is made.(21)

Allergic eosinophilic gastritis or gastroenteritis

The verbal cause of these disorders remains unknown although both IgE-mediated and T-cell-mediated reactions take been implicated. These weather condition are characterized by infiltration of eosinophils in the mucosal, muscular and/or serosal layers of the stomach or pocket-sized intestines. Patients nowadays with postprandial nausea and vomiting, abdominal pain, diarrhea (occasionally steatorrhea) and weight loss in adults and failure to thrive in young infants.

Diagnosis of Nutrient Allergy

The results of skin prick tests (SPT), IgE total and specific antibodies, and patient histories are not predictive of truthful nutrient allergy, every bit they are not able to constitute the causal and temporal human relationship between the intake of the suspect food and the hypersensitivity reaction. The negative predictive accurateness of a skin prick examination weal of < 3mm greater than the negative command is high, usually > 95%, and is strong bear witness that the nutrient may be consumed without astringent, immediate nutrient-allergic reactions. A positive SPT, fifty-fifty a weal of iii mm or more, may be clinically irrelevant, equally the patient may tolerate the ingested food. SPTs may likewise remain positive subsequently the development of tolerance to the specific food.

Specific IgE levels brandish a variable diagnostic accuracy according to the nature of the allergen, the studied population, the specific make of the test. Using the virtually popular diagnostic systems, in is conventionally accepted that 0.35 kU/l is the cutting-off level for a positive in-vitro test of specific IgE. Higher levels of specific IgE for food allergens may meliorate correlate with clinical reactivity as evidenced by challenge testing. For this reason, decision points have been proposed. While valid in the studied populations, the value of such decision points cannot be universal (see table below).

A double blind, placebo-controlled nutrient challenge (DBPCFC) is the preferred test to diagnose food allergy^3,xix. DBPCFC should be performed in specialist centers with close supervision. Resuscitation facilities and overnight admission can be necessary in astringent cases. DBPCFC is difficult to organize in many clinical situations, and can be replaced by open challenges in many situations (when at that place is a minimal risk of false interpretations due to subjective factors). When a psychological reaction is strongly suspected, a single-blinded test may too be used (22, 23).

The in vitro diagnostics tin can help to identify cantankerous-reactive allergens betwixt pollen and foods, or foods and latex. Cross-reactive allergens include common lipid transfer proteins (LTPs), PR molecules, and profilin. Skin prick/puncture tests using commercial extracts to the implicated fruit are often negative, but a positive examination may be obtained using a drop of fresh juice from the incriminated fruit.

The atopy patch examination (APT) is an epicutaneous skin test in which allergens commonly associated with IgE reactions tin exist used, although patch testing is more commonly performed for metals such every bit nickel, which causes a positive patch test in nickel sensitive subjects. Although the pathogenic mechanisms of the APT have not been fully elucidated, a positive APT tin can predict a late stage reaction post-obit oral food claiming. A positive APT may detect clinically relevant late phase eczematous or GI reactions in infants and children (24). This examination is not useful for IgE-mediated nutrient allergy. It is considered experimental in about parts of the world (25).

Prevention of food allergy

Co-ordinate to all the current guidelines, an baby with at to the lowest degree one first-degree relative (parent or sibling) with a history of allergic disease' (26, 27) in item allergic rhinitis, asthma, eczema, or food allergy (28, 29) is at greater take a chance for developing nutrient allergy.

The first proposed recommendation for a large-scale prevention of food allergy has been the use of hypoallergenic (HA) formulae in example of breastfeeding failure. This arroyo has reached the level of bear witness to exist included in the NIAID recommendations on food allergy prevention (thirty), but it has subsequently been questioned. (31) Earlier guidelines on allergy prevention recommended delayed exposure to solid foods, avoidance of allergenic foods, and did not include interventions aimed at promoting the infants' immune tolerance (32). Emerging evidence, however, has led to a paradigm shift, supporting nutritional approaches such every bit appropriate timing of nutrient exposure, and utilize of prebiotics and probiotics for allergy prevention. The Learning Early virtually Peanut (LEAP) written report showed that early on introduction of peanuts significantly decreased the frequency of peanut allergy amongst children at loftier risk, and modulated immune responses to peanuts (33). Hence, based on these findings, the National Institutes of Health (NIH) Guidelines for the Direction and Prevention of Food Allergy after recommended the introduction of peanut-containing foods to "loftier-run a risk" infants early in life (four-11 months) (34).

The World Allergy Organization (WAO)/McMaster Working Group Guidelines for Allergic Illness Prevention (GLAD-P) has also published GRADE recommendations on the utilize of probiotics and prebiotics for allergy prevention based on current available evidence. The guideline panel suggested using probiotics in meaning and breastfeeding women whose children and infants are at high risk for developing allergy²⁹. Probiotics have been shown by numerous studies to be effective in allergy prevention, specially in reducing allergic eczema at a rate of 9 fewer cases per 100 pregnant women (risk ratio [RR] 0.72), 16 fewer cases per 100 breastfeeding women (RR 0.58), and five fewer cases per 100 infants (RR 0.82). Ultimately, the use of probiotics should be individualized and further studies are needed to evaluate their effect in preventing other types of allergy and the differences among the strains of the same species of probiotic bacteria.

Concerning prebiotics, GLAD-P conditionally recommends prebiotic supplementation in non-exclusively breastfed infants, both at high and at depression risk for developing allergy, only not in exclusively breastfed infants (35). These recommendations were largely based on a meta-analysis of bachelor evidence showing that prebiotic supplementation reduces the risk of developing asthma or recurrent wheezing (RR: 0.37, 95 % CI: 0.17 to 0.80) and the risk of developing food allergy (RR: 0.28, 95 % CI: 0.08 to i.00) (36). Information technology has been proposed that these furnishings effect from interactions betwixt the gut microbiota and the gut mucosal allowed arrangement.

GLAD-P provides no recommendation at this time on prebiotic utilise in pregnant and breastfeeding women, attributable to the lack of evidence from experimental and observational studies.

In the future, the GLAD-P guidelines may be expanded as more information from rigorously designed, adequately powered and well-executed trials become available. Recommendations on other interventional measures, such equally vitamin D supplementation, in allergy prevention are negative (37).

Handling

Food Allergen Avoidance

The foods to which an individual is allergic should be avoided, as therapeutic intervention (3rd prevention) in patients with food allergy.  It must strike a precautionary equilibrium between the demands of prohibitive measures confronting allergy intendance and quality of life. Such a dynamic endpoint is difficult to assess for efficacy and safety. Avoidance measures need to be tailored to the individual's life and illness requirements must take account o  the needs of growth, the prevention of anaphylaxis and, of the benefits expected of allergen avoidance itself.

From the patient'south perspective, avoidance means meeting obstacles unshared by their not-allergic peers, thereby curtailing their quality of life.  From the dr.'s outlook, educational activity, ensuring compliance and receptiveness of both patient and caregiver are major concerns. The role of the allergist is to review in a dialectical cess these competing factors in concert with all parties concerned. Where avoidance of the implicated nutrient may result in nutritional deficiency, dietary supplementation is necessary³.

Candy foods may contain hidden proteins, e.g., milk, egg and soy proteins may be added to increase the protein content or heighten flavor. Peanuts and nut products are added to thicken and season sauces. Patients tin can exist taught to identify hidden food components in processed foods. Commonly used 'hidden' proteins are casein and lactose, derived from milk, and albumin from egg. To disembalm subconscious food allergens, food labelling is an outcome of relevance to nutrient allergic consumers of processed or pre-packaged foods. In the European Marriage, 12 food items are required by police force to appear on the characterization: cereals containing gluten, crustaceans, egg, fish, peanut, soy, milk (including lactose), tree nuts, mustard, sesame seeds, celery, and sulfites >ten mg/kg (38). Similar legislation is in result in the US, where the 2006 Food Allergen Labeling and Consumer Protection Human action provides that all food products require an ingredient statement. In these countries, the legislation has altered industry practices in some important aspects for milk, egg, peanut, tree basics, shellfish, fish, soy and wheat. In other countries, hidden allergens tin can be exempt from specific labeling, and thus exist inadvertently consumed by food allergic individuals.  On both the sides of Atlantic, the regulatory problem is now the opposite business concern, that is, whether besides many foods containing trace amounts of these allergenic foods are existence "overlabeled" and whether this would then potentially restrict potentially safe nutrient choices for allergic consumers.  In fact, the labeling regulations exercise non prescribe the indication of potential contaminants, just many manufacturers are now indicating, "may contain" as a alarm of potential contaminations during food preparation (39).

Pharmacological therapy

Hypersensitivity reactions are often treated with medications. . Epinephrine is the only medication that is effective for the handling of anaphylaxis. Boosted medicatioons  include H_ane and H₂ antihistamines, corticosteroids, and prostaglandin synthetase inhibitors These drugs are only symptomatic, do not modify the natural course of the disease, and sometimes have unacceptable side effects. Anti-IgE monoclonal antibodies therapy is  licensed for use in asthma and for chronic urticaria in many countries, and studies are under way to make up one's mind if it has a role in the management of serious food allergies.

Oral Immunotherapy

Whatsoever desensitisation protocol to both reduce the hazard of major reactions and avoid nutritional restrictions in children suffering from nutrient allergy would be highly beneficial. The subcutaneous assistants of native (40) or modified (41) peanut extracts was attempted in the past, just the shots induced systemic reactions or serious agin effects. In the last years, the experience with oral immunotherapy has made this a common, accepted treatment in some countries. A recent systematic review concluded that oral immunotherapy is no longer experimental, just is ready for applied application (42). Information technology should exist applied to reduce the risk of inadvertent reactions, and not to modify the natural course of the affliction (43). "Tolerance" in "desensitized" children disappears if the allergen is not ingested every 24-hour interval in therapeutic doses. However, research is ongoing and the future use of recombinant allergens (44), synthetic peptides (45),and epicutaneous therapy for desensitization in humans looks more promising (46).

Natural history

One of the nearly often asked parents' questions is "How long will my child'south food allergy terminal?"   Given the present impossibility to change the natural history of food allergy, the answer must take into account a series of factors. There is a relationship between symptom severity afterwards ingestion and the likelihood of outgrowing the problem; the more severe the reaction, the less likely that the food allergy volition be outgrown.  Other factors, such every bit sIgE antibody level and age at diagnosis, have also been associated with prognosis of food allergy, although these associations are not invariably consistent beyond studies (47, 48, 49). Milk allergy'south half-life is approximately two years while egg allergy's half-life is  approximately four years. Peanut allergy, once considered to be a life-long condition, can resolve in up to 30% of cases (50). However, it is non possible to establish a half-life for a diagnosis of peanut allergy and tree nuts should still exist considered equally lifelong allergies.

Similarly, fish allergy is considered a long-lasting status and reports of recovery are rare (51). Still, no study has evaluated the natural history of fish allergy in infants and fish should also be regarded as causing persistent allergies.

While peanut, tree nut, fish and seafood allergy are generally persistent conditions, fiddling is known about the natural history of allergy to such staples as fruits, vegetables, cereals and meat.

In food allergic children, tolerance must be tested by oral challenge at regular intervals. Frequently tolerance is not acquired all of a sudden, just there is a gradual increment of the doses tolerated at challenge. Fifty-fifty afterwards years of apparent clinical tolerance, gastrointestinal symptoms of nutrient allergy and reduced growth, . Epinephrine is the only medication that is effective for the treatment of anaphylaxis.  take been reported (52).
