• #1 Wheat allergy: diagnosis and management

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4743586/

  Triticum aestivum (bread wheat) is the most widely grown crop worldwide. In genetically predisposed individuals, wheat can cause specific immune responses. A food allergy to wheat is characterized by T helper type 2 activation which can result in immunoglobulin E (IgE) and non-IgE mediated reactions. IgE mediated reactions are immediate, are characterized by the presence of wheat-specific IgE antibodies, and can be life-threatening. Non-IgE mediated reactions are characterized by chronic eosinophilic and lymphocytic infiltration of the gastrointestinal tract. […] Diagnosis of IgE mediated wheat allergy is based on the medical history, the detection of specific IgE to wheat, and oral food challenges. Currently, the main treatment of a wheat allergy is based on avoidance of wheat altogether.

  A wheat allergy can be deadly. If you have severe allergic reaction symptoms, such as swelling in your throat, call 911 or go to your nearest emergency room (ER) immediately. […] An allergist is a healthcare provider who specializes in allergies. They can help you diagnose your wheat allergy through tests especially if theyre due to an IgE-mediated reaction. […] Your allergist may use different allergy tests to help diagnose your wheat allergy based on your symptoms. These tests may include: […] This test exposes your body to small amounts of wheat proteins. […] During a blood test, a laboratory technologist will use a thin needle to withdraw a small amount of blood from a vein in your arm. […] If you dont get conclusive results from a skin prick test or a blood test, your allergist may order a graded oral challenge.

  Diagnosis of an allergy can be made through a skin-prick test or a blood test. […] In the skin-prick test, a small amount of a liquid containing wheat protein is placed on the back or forearm, which is then pricked with a small, sterile probe to allow the liquid to seep into the skin. If a raised, reddish spot forms within 15 to 20 minutes, that can indicate an allergy. […] In the blood test, a blood sample is sent to a laboratory to test for the presence of immunoglobulin E antibodies to wheat protein. The results are reported as a numerical value. A blood test that looks for different antibodies can be used to screen for celiac disease. […] If these tests aren’t definitive, your allergist may order an oral food challenge. Under medical supervision, you’ll eat small amounts of wheat to see if a reaction develops. Because of the possibility that a reaction could be severe, this test is conducted in your allergist’s office or at a food challenge center with emergency equipment and medication on hand.

  There are different types of allergy and intolerances to wheat here we focus on immediate wheat allergy. […] They can help you get a diagnosis. […] If you think you may be allergic to wheat, see your GP who can refer you to a specialist allergy clinic if needed. […] If you are referred to an allergy clinic, the consultant will discuss your medical history and symptoms with you. They might suggest skin prick tests, blood tests, and food challenge tests to help diagnose the allergy and work out how serious it may be. […] Many people with an allergy to grass pollen will have a positive skin test to wheat, as wheat and grass pollen contain some of the same proteins. […] Keeping a food and symptom diary like this will help your allergy specialist or dietitian make a diagnosis. […] Wheat allergy is most common in children and is usually outgrown in the pre-school years.

  The exact level of IgE that predicts whether the reaction is a true allergy in over 90% of patients is not well known. […] Generally, children with even high levels of IgE can tolerate certain foods when undergoing an oral food challenge, and thus it is difficult to correlate an IgE level to a wheat allergy. […] Moreover, an evaluation of a wheat allergy should be done by a health care provider as there is a potential risk of anaphylaxis and the need for epinephrine. […] For those being worked up for WDEIA, SPT or specific IgE to wheat, gluten, and omega-5-gliadin should be ordered. […] The gold standard to confirm the diagnosis of wheat-induced occupational allergy is a bronchial challenge test which consists of a nebulized aqueous flour solution in increasing concentrations (0.01, 0.1, 10, and 100 mg/mL) or by inhaling wheat flour dust.

  Blood test: A blood test for wheat IgE looks for an immune protein that’s directed against wheat. If you have symptoms of a wheat allergy and abnormal wheat IgE levels, this is a sign that you have a wheat allergy. […] One caveat of both blood and skin testing for wheat allergy is that they are both sensitive tests but not very specific. This means that some people can test positive for wheat allergy even if they have no history of wheat reactions. It is not recommended to have a test for wheat allergy if you don’t have symptoms.

[…] A step-by-step process which involves consuming small amounts of a suspected allergen over 3 to 4 hours. […] Recent studies have shown that wheat allergy can be successfully treated with oral immunotherapy (OIT) in patients of all ages. […] Oral immunotherapy works by routinely exposing the patient to increasing amounts of the foods they are allergic to. […] Each diagnosis requires its own treatment plan, and consuming gluten-free products may only address some symptoms. […] Improperly addressing symptoms (or delaying adequate treatment) of a wheat-related disease can cause long-term or severe side effects, making accurate clinical diagnosis a crucial step.

  A physical exam, detailed medical history and some tests will help your doctor make a diagnosis. Tests or diagnostic tools may include: […] Skin test. Tiny drops of purified allergen extracts including extracts for wheat proteins are pricked onto your skin’s surface, either on your forearm or on your upper back. After 15 minutes, your doctor or nurse looks for signs of allergic reactions. […] Blood test. If a skin condition or possible interactions with certain medications prevent you from having a skin test, your doctor may order a blood test that screens for specific allergy-causing antibodies to common allergens, including wheat proteins. […] Food diary. Your doctor may ask you to keep a detailed record of what and when you eat and when symptoms develop for a time. […] Elimination diet. Your doctor may recommend that you remove certain foods from your diet, particularly those that are common allergens. Under your doctor’s direction, you will gradually add foods back and note when symptoms return.

  If you notice certain symptoms after eating cereal, bread or pasta — for instance, if you develop hives or a rash or get a stomachache, or your nose gets stuffy or runs — you may have a wheat allergy, a condition that affects millions of Americans. […] Wheat allergy is most common in children; about two-thirds of them outgrow it at a relatively young age. Though many patients with wheat allergy can eat other grains, that’s not true for everyone. Talk with your allergist about what you can safely eat and what you should avoid, so you and your children can live the lives you want. […] Some indications of an allergy to wheat — stomach cramps, diarrhea and other gastrointestinal symptoms — overlap with those produced by a sensitivity to gluten or by celiac disease, an autoimmune disorder, so it’s crucial to get an accurate diagnosis. An allergist can determine whether an allergy is present.

• #1 Wheat Allergy – ECARF

  https://www.ecarf.org/en/information-portal/allergies-overview/wheat-allergy/

  If WDEIA is suspected, the blood is tested for the presence of antibodies to omega-5 gliadin, the main allergen involved in this type of wheat allergy. If a provocation test is performed, the patient is given the wheat protein and the suspected trigger is simulated in addition for example, by having the patient exercise on a stationary bike. […] If wheat causes gastrointestinal problems, the patient must be tested for both an allergy and coeliac disease, a serious disorder in which the body produces antibodies to gluten (which is found not only in wheat but also in other types of grains). This results in chronic inflammation in the small intestine and damage to the intestinal villi. In addition to bloating and abdominal pain, diarrhoea occurs frequently. There may also be symptoms of mineral and vitamin deficiencies (such as iron deficiency and osteoporosis). The joints, liver, skin and nervous system can also be affected. Coeliac disease is diagnosed through tests for specific antibodies, genetic analysis, and the analysis of a tissue sample from the small intestine. A diagnosis can only be made if the patients diet includes gluten. If bread and pasta have been excluded for some time, the disease cannot be confirmed. If coeliac disease is diagnosed, the patient must strictly avoid gluten, since even small amounts of gluten can damage the intestinal mucosa.

  For celiac disease, measurement of serum immunoglobulin A antibody to tissue transglutaminase (anti-tTG) should be the first screening test ordered. […] Primary treatment and management of wheat allergies is avoidance of both food and inhaled wheat allergens. […] In cases of exposure and an anaphylactic reaction, the administration of epinephrine is the lifesaving treatment. […] Patients who have signs or symptoms of a wheat allergy should see a doctor as soon as possible as it can be a life-threatening disease. […] Those who are already diagnosed should make sure they avoid wheat and always carry epinephrine.

  https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

  A simple blood test is available to test for celiac disease. People with celiac disease who eat gluten have higher than normal levels of certain antibodies in their blood. These antibodies are produced by the immune system because it views gluten (the proteins found in wheat, rye, and barley) as a threat. You must be on a gluten-containing diet for antibody (blood) testing to be accurate. […] For most children and adults, the best way to test for celiac disease is with the Tissue Transglutaminase IgA antibody (tTG-IgA), plus an IgA antibody in order to ensure that the patient generates enough of this antibody to render the celiac disease test accurate. […] There are other antibody tests available to double-check for potential false positives or false negatives, but because of potential for false antibody test results, a biopsy of the small intestine is the only way to diagnose celiac disease.

• #1 Non-Celiac Gluten Sensitivity | BeyondCeliac.org

  https://www.beyondceliac.org/celiac-disease/non-celiac-gluten-sensitivity/

  An allergic reaction is when a body’s immune system attacks a foreign substance. Allergies, including those to wheat, are associated with positive IgE assays. Diagnosis is made through skin prick tests, wheat-specific IgE blood testing and a food challenge. People who have gluten-related symptoms but test negative for a wheat allergy and do not test positive for celiac disease may have gluten sensitivity. […] Currently, there are no recommended methods to test for non-celiac gluten sensitivity. It is a diagnosis of exclusion, which means that other causes, including celiac disease and wheat allergy, need to be ruled out and the patient needs to feel better on the gluten-free diet. Some doctors offer saliva, blood or stool testing. However, these tests have not been validated and are therefore not accepted.

• #1 Diagnosis of gluten related disorders: Celiac disease, wheat allergy and non-celiac gluten sensitivity

  https://www.wjgnet.com/1007-9327/full/v21/i23/7110.htm

  The identification of molecular allergens for laboratory methods has profoundly changed the diagnostic approach to allergic diseases in the recent years. […] The diagnosis of WA is not easily diagnosed with conventional SPT or sIgE assays using wheat flour extracts, since their diagnostic predictivity is unsatisfactory. […] To date, NCGS is mainly a diagnosis of exclusion made after other wheat-related and non-wheat-related disorders have been ruled out. […] A more appropriate standard for the confirmation of NCGS would be an elimination diet followed by double-blind placebo-controlled gluten challenge. […] The suggested approach is similar to the adults, recommending a gluten challenge after at least 8 wk on GFD.

• #1 Routinely Used and Emerging Diagnostic and Immunotherapeutic Approaches for Wheat Allergy

  https://www.mdpi.com/2227-9059/12/7/1549

  The most commonly adopted diagnostic methods of WA are SPT and sIgE measurement. Although the latter enjoys higher sensitivity, these tests are both of low specificity. […] This concern has been addressed by promising wheat extract formulations with gliadin and glutenin-solubilizing properties, which yielded better accuracy for diagnosing WA in children than their preceding commercial wheat extracts. […] In recent years, component-resolved diagnosis (CRD) has been increasingly utilized to identify specific components that can predict clinical reactions in cases of IgE-mediated WA and WDEIA. […] Measurement of basophil CD203c expression induced by various preparations of wheat proteins, particularly ω-5 gliadin, is also useful in predicting causative allergens in patients with WA and WDEIA.

  This approach offers advantages over the use of a complete extract alone, especially in polysensitized individuals, given its usefulness for distinguishing between sensitizations specific to singular species and sensitizations due to cross-reactivity. […] The protein composition of wheat is complex and can be broadly divided into three major fractions based on extraction method: 1) water soluble albumins; 2) salt-soluble globulins; and 3) insoluble prolamins (gliadins and the glutenins). […] In addition to the wheat extract sIgE test, ImmunoCAP tests are now available for a number of wheat-specific and wheat extract cross-reactive components that can aid in the diagnostic workup of potential wheat allergy. […] The clinical expression of wheat allergy can be quite diverse due to different routes and amounts of exposure and the diversity of populations affected.

  The intermittent nature of the condition, its relative rarity and the lack of recognition by physicians often frequently results in a prolonged time lag to diagnosis of this condition. […] Tri a 19 has been shown to be the major sensitizer for WDEIA. […] A recent study of Japanese patients with WDEIA found that the majority (85%) of patients with Tri a19 sIgE-associated WDEIA maintained elevated Tri a 19 sIgE over time during several years of observation. […] Contact urticaria with use of cosmetics is relatively common, and hydrolyzed wheat should always be thought as one possible inducer.

  A precise diagnosis of an IgE-mediated wheat food and respiratory allergy is tremendously important, as avoidance is a critical step in clinical management, and no commercial products for allergen-specific immunotherapy are currently available. […] The molecular allergy diagnostic approach to IgE-mediated WA uses allergen components in singleplex and multiplex immunoassays. […] Currently, there are several commercially available wheat allergen molecules for in vitro diagnostic purposes: nGliadin, rTri a 19, rTri a 14 and nTri a aA_TI. […] The fluorescence enzyme immunoassay (FEIA) with capsulated cellulose polymer solid-phase coupled allergens is currently used as a solid-phase singleplex immunoassay to measure specific IgE antibodies to gliadin, Tri a 19 and Tri a 14. […] The ELISA-based macroarray immunoassay uses nano-bead technology as a molecular allergy explorer with allergen components spotted onto a nitrocellulose membrane in a cartridge chip using anti-human IgE labeled with alkaline phosphatase.

  The Flow CAST (Cellular Allergy Stimulation Test) is the standardized and assessable basophil activation test (BAT), which may be used for the quantitative assessment of in vitro basophil activation by wheat proteins, including omega-5 gliadin and HMW glutenin subunits. […] Concentrations of serum IgE to rTri a 19 higher than a cut-off of 0.89 kU/L may confirm the WDEIA diagnosis with a 78–80% sensitivity and 96% specificity, while the specific IgE sensitivity for whole wheat extract and gluten is low, at 48% and 56%, respectively. […] The accurate diagnosis of IgE-mediated wheat food and respiratory allergies is paramount, especially when considering the crucial role of avoidance in clinical management, particularly in the absence of commercially available products for allergen-specific immunotherapy.

  Triticum aestivum (bread wheat) is the most widely grown crop worldwide. In genetically predisposed individuals, wheat can cause specific immune responses. A food allergy to wheat is characterized by T helper type 2 activation which can result in immunoglobulin E (IgE) and non-IgE mediated reactions. IgE mediated reactions are immediate, are characterized by the presence of wheat-specific IgE antibodies, and can be life-threatening. Non-IgE mediated reactions are characterized by chronic eosinophilic and lymphocytic infiltration of the gastrointestinal tract. […] Diagnosis of IgE mediated wheat allergy is based on the medical history, the detection of specific IgE to wheat, and oral food challenges. Currently, the main treatment of a wheat allergy is based on avoidance of wheat altogether. However, in the near future immunotherapy may represent a valid way to treat IgE mediated reactions to wheat.

  Diagnosis of an allergy can be made through a skin-prick test or a blood test. […] In the skin-prick test, a small amount of a liquid containing wheat protein is placed on the back or forearm, which is then pricked with a small, sterile probe to allow the liquid to seep into the skin. If a raised, reddish spot forms within 15 to 20 minutes, that can indicate an allergy. […] In the blood test, a blood sample is sent to a laboratory to test for the presence of immunoglobulin E antibodies to wheat protein. The results are reported as a numerical value. A blood test that looks for different antibodies can be used to screen for celiac disease. […] If these tests aren’t definitive, your allergist may order an oral food challenge. Under medical supervision, you’ll eat small amounts of wheat to see if a reaction develops. Because of the possibility that a reaction could be severe, this test is conducted in your allergist’s office or at a food challenge center with emergency equipment and medication on hand.

  If WDEIA is suspected, the blood is tested for the presence of antibodies to omega-5 gliadin, the main allergen involved in this type of wheat allergy. If a provocation test is performed, the patient is given the wheat protein and the suspected trigger is simulated in addition for example, by having the patient exercise on a stationary bike. […] If wheat causes gastrointestinal problems, the patient must be tested for both an allergy and coeliac disease, a serious disorder in which the body produces antibodies to gluten (which is found not only in wheat but also in other types of grains). This results in chronic inflammation in the small intestine and damage to the intestinal villi. In addition to bloating and abdominal pain, diarrhoea occurs frequently. There may also be symptoms of mineral and vitamin deficiencies (such as iron deficiency and osteoporosis). The joints, liver, skin and nervous system can also be affected. Coeliac disease is diagnosed through tests for specific antibodies, genetic analysis, and the analysis of a tissue sample from the small intestine. A diagnosis can only be made if the patients diet includes gluten. If bread and pasta have been excluded for some time, the disease cannot be confirmed. If coeliac disease is diagnosed, the patient must strictly avoid gluten, since even small amounts of gluten can damage the intestinal mucosa.

• #2 Non-Celiac Gluten Sensitivity | BeyondCeliac.org

  https://www.beyondceliac.org/celiac-disease/non-celiac-gluten-sensitivity/

  An allergic reaction is when a body’s immune system attacks a foreign substance. Allergies, including those to wheat, are associated with positive IgE assays. Diagnosis is made through skin prick tests, wheat-specific IgE blood testing and a food challenge. People who have gluten-related symptoms but test negative for a wheat allergy and do not test positive for celiac disease may have gluten sensitivity. […] Currently, there are no recommended methods to test for non-celiac gluten sensitivity. It is a diagnosis of exclusion, which means that other causes, including celiac disease and wheat allergy, need to be ruled out and the patient needs to feel better on the gluten-free diet. Some doctors offer saliva, blood or stool testing. However, these tests have not been validated and are therefore not accepted.
