  The exact etiology of EoE is unknown; however, it is thought to be a result of the interactions of environmental, genetic, and host immune factors. […] A food allergy may trigger EoE, but food anaphylaxis is a rare phenomenon among these patients. […] There is a strong correlation between atopy and EoE, with patients commonly reporting a history of chronic seasonal allergy, asthma, atopic dermatitis, or other allergic/immunologic conditions.

• #2 Do we know what causes eosinophilic esophagitis? A mechanistic update

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4591257/

  The mechanisms underlying eosinophilic esophagitis (EoE) have been intensely investigated, and significant advances have been made in understanding the pathogenesis of EoE. EoE is defined as a chronic immune/antigen-mediated disease, characterized clinically by symptoms of esophageal dysfunction and histologically by an esophageal eosinophilic infiltrate. […] EoE is a Th2-predominant inflammatory process triggered by allergens. Proinflammatory cytokines and chemokines recruit eosinophils and other effector cells, such as mast cells, into the esophageal epithelium, where they cause direct damage and promote esophageal remodeling. […] While this genetic contribution is important, it is difficult to postulate that EoE is primarily a genetic disease. Given the rapid epidemiologic changes in the incidence and prevalence of EoE over the past two decades, environmental factors may be the driving force.

  Eosinophilic esophagitis (e-o-sin-o-FILL-ik uh-sof-uh-JIE-tis) is a chronic immune system disease. […] This buildup, which is a reaction to foods, allergens or acid reflux, can inflame or injure the esophageal tissue. […] Eosinophils are a typical type of white blood cells present in your digestive tract. However, in eosinophilic esophagitis, you have an allergic reaction to an outside substance. The reaction may occur as follows: […] The lining of your esophagus reacts to allergens, such as food or pollen. […] The eosinophils multiply in your esophagus and produce a protein that causes inflammation. […] Inflammation can lead to scarring, narrowing and formation of excessive fibrous tissue in the lining of your esophagus. […] There has been a significant increase in numbers of people diagnosed with eosinophilic esophagitis in the past decade. […] However, studies now suggest that the disease is becoming increasingly common, parallel to the increase in asthma and allergies.

  Population studies show a steady rise in the incidence (6.6 per 100,000 person-years) and prevalence (34 per 100,000) of Eosinophilic Esophagitis (EoE) in children. […] The etiology of EoE is not completely understood, but like other atopic diseases, it appears to result from an interplay between genetics and environment. […] The marked increase in the diagnosis of EoE along with data from twin studies indicate that environmental factors likely play a large role in the etiology of EoE. […] Environmental factors that are reliably associated with EoE include: Food allergens Milk is the most common food trigger of EoE (followed by wheat, egg, and soy) […] Antibiotics in infancy Similar to observational studies for other atopic conditions, antibiotic use in infancy is correlated with a higher risk of EoE, but causality has not been established.

• #6 Eosinophilic Esophagitis (EoE) Pathology: Definition, Etiology, Epidemiology

  https://emedicine.medscape.com/article/1610470-overview

  EoE has been hypothesized to be an atopic inflammatory disease. The etiopathogenesis is hypothesized to be an aberrant immune response to antigenic stimulation. […] The atopic/allergenic nature of antigen is supported by studies that report a climatic and seasonal variation in presentation. […] Most of these studies show an increase in new cases during spring or fall and some during summer. A high prevalence of EoE in cold and arid zones in the United states also supports the role of environmental factors in EoE. […] The esophagus is unique from the rest of the gastrointestinal tract as eosinophils are not a part of normal histology in esophagus. […] In the late 1990s, murine studies demonstrated that eotaxin, an eosinophil chemoattractant chemokine, plays an important role in homing of eosinophils to the mucosal surface of the gastrointestinal tract.

  https://www.aaaai.org/conditions-treatments/related-conditions/eosinophilic-esophagitis

  Eosinophilic (e-o-sin-o-FILL-ik) esophagitis (EoE) is a recognized chronic allergic/immune condition of the esophagus. In EoE, large numbers of white blood cells called eosinophils are found in the inner lining of the esophagus. Eosinophils can release substances into surrounding tissues that cause inflammation. A person with EoE will have inflammation and increased numbers of eosinophils in the esophagus. The majority of patients with EoE are atopic. EoE may occur in other family members. Environmental allergies to substances such as pollens, animals, dust mites and molds possibly play a role in EoE. Immune reactions to foods are the main cause of EoE in most patients. Foods such as dairy products, wheat, egg, and soy are recognized as the most common triggers for EoE. A person with EoE may have one or more foods triggering their EoE. Once the causative food(s) is (are) identified and removed from a persons diet, esophageal inflammation and symptoms generally improve in a few weeks.

  Eosinophilic esophagitis (EoE) is a chronic inflammatory disease. The etiopathogenesis of this disease has not yet been fully elucidated. The current data show that the immune cells present in the esophagus, which are hyperstimulated by antigens (for example, food antigens), release numerous pro-inflammatory cytokines such as interleukin (IL)-4, IL-5, and IL-13. This drives the entire mechanism of the disease as eosinophils are recruited to stimulate a further inflammatory response. […] The main response is the T helper 2 (Th-2) immune response, during which there is a secretion of Th-2 type cytokines, such as IL-4 IL-5, IL-13, eotaxin-3, and periostin. The increased frequency of CD4 + Th-2 cells was found in patients with EoE in peripheral blood and esophageal biopsy specimens. […] There are many studies describing the role of food antigens in the pathogenesis of EoE. Several observations support the idea that food plays an important role in triggering an immune response.

  The same group of researchers subsequently reported that interleukin (IL)-5, a Th2 cytokine, plays an important role in the induction of eosinophil trafficking to the esophagus. […] Another study demonstrated that delivery of another Th2 cytokine IL-13 to lungs induces EoE by inducing IL-5, eotaxin-1, through signal transducer and activation of a transcription (STAT)6 dependent mechanism. […] The results of this study established a link between lung and esophageal inflammation and suggested that direct exposure of esophageal mucosa to an allergen is not necessary for EoE to develop. […] An in vitro study involving human esophageal mucosal tissue by Straumann et al demonstrated that EoE induces a selective inflammatory response restricted to the esophagus and includes infiltration of esophageal mucosa by IL-5 expressing T-cells, B-cells, and eosinophils and immunoglobulin (Ig) E expressing mast cells.

  Eosinophilic oesophagitis (EoE) occurs when white blood cells called eosinophils build up in the lining of the oesophagus, which is the muscular tube that connects the mouth to the stomach. This can be due to an allergic reaction to food or other causes in the environment. […] Most cases of EoE are seen in people with other allergies such as allergic rhinitis (hay fever) and asthma. The number of adults and children with EoE appears to be increasing but it is not known why. […] When food is the cause of EoE, cow’s milk (dairy products), wheat and egg are the most common triggers. Soy, seafood and nuts can also be triggers. Some studies have found that people with EoE may benefit if these foods are removed from the diet. […] There are currently questions about the role of allergy and diet in EoE that need to be answered by more research. In some people, symptoms may get better with changes to the diet, but the biopsy will still show inflammation. It is still unclear whether the aim should be to settle symptoms only, or to also control inflammation.

  Eosinophilic esophagitis (EoE) is a chronic inflammatory disease. The etiopathogenesis of this disease has not yet been fully elucidated. The current data show that the immune cells present in the esophagus, which are hyperstimulated by antigens (for example, food antigens), release numerous pro-inflammatory cytokines such as interleukin (IL)-4, IL-5, and IL-13. This drives the entire mechanism of the disease as eosinophils are recruited to stimulate a further inflammatory response. […] The main response is the T helper 2 (Th-2) immune response, during which there is a secretion of Th-2 type cytokines, such as IL-4 IL-5, IL-13, eotaxin-3, and periostin. The increased frequency of CD4 + Th-2 cells was found in patients with EoE in peripheral blood and esophageal biopsy specimens. […] There are many studies describing the role of food antigens in the pathogenesis of EoE. Several observations support the idea that food plays an important role in triggering an immune response. Firstly, a very large percentage of patients achieve disease remission if a specific food that potentially causes an allergy reaction is eliminated. Secondly, the re-introduction of identified food triggers leads to disease recurrence.

  Eosinophilic esophagitis is an inflammatory condition in which the wall of the esophagus becomes filled with large numbers of eosinophils, a type of white blood cell. […] Doctors believe that eosinophilic esophagitis is a type of esophagitis that is caused by an allergen for two reasons: […] Nevertheless, the exact substance that causes the allergic reaction in eosinophilic esophagitis is unknown. […] As previously mentioned, the allergen(s) that causes eosinophilic esophagitis is unknown. It is not even known whether the allergen is inhaled or ingested. […] The leading theory about the cause of eosinophilic esophagitis is that it represents an allergy to some protein found in food. Evidence has accumulated in children that diets that eliminate allergy-inducing food can result in the reversal of esophagitis and the disappearance of the eosinophils. Similar evidence now is accumulating in adult patients. […] More studies are needed to determine whether cromolyn is effective in treating eosinophilic esophagitis.

  The relationship between food allergy and EoE is complex. In EoE, it is more difficult to establish the role of foods because the reactions are delayed, and can develop over days, making it harder to pinpoint a specific food as the trigger. […] Unfortunately, skin testing, blood allergy testing, and patch testing do not reliably identify food triggers of EoE. This is because most food allergy reactions in EoE are delayed and caused primarily by immune mechanisms other than classical IgE-mediated food allergy.

  https://www.carolinadigestive.com/blog-post/eosinophilic-esophagitis-symptoms-and-causes

  At a basic level, the inflammation central to eosinophilic esophagitis is a reaction to an allergen; the current prevailing thought is that food allergies are the primary trigger. […] The main cause of eosinophilic esophagitis is simply the presence of an abnormally large quantity of eosinophils in the esophagus; as noted earlier, the eosinophils cause inflammation, and the inflammation leads to the various symptoms. […] Food Allergens: Recent research has shown that food allergies may be one of the key factors in eosinophilic esophagitis, but it is difficult to diagnose because the allergic response is different when compared to other conditions; for example, many food allergies cause an immediate reaction (like hives), but in eosinophilic esophagitis, the reaction is delayed. […] Aeroallergens: Aeroallergens are airborne substances that cause an allergic reaction. In patients with eosinophilic esophagitis, pollen, mold, dust mites, or animals may be the agents responsible for the immune response that leads to eosinophils gathering in the esophagus. […] Genetics: Some recent research has found that a gene known as eotaxin-3 might make individuals genetically predisposed to getting eosinophilic esophagitis; the eotaxin-3 gene is responsible for a protein that controls the accumulation of eosinophils.

  Eosinophilic (e-o-sin-o-FILL-ik) esophagitis (EoE) is a recognized chronic allergic/immune condition of the esophagus. In EoE, large numbers of white blood cells called eosinophils are found in the inner lining of the esophagus. Eosinophils can release substances into surrounding tissues that cause inflammation. A person with EoE will have inflammation and increased numbers of eosinophils in the esophagus. The majority of patients with EoE are atopic. EoE may occur in other family members. Environmental allergies to substances such as pollens, animals, dust mites and molds possibly play a role in EoE. Immune reactions to foods are the main cause of EoE in most patients. Foods such as dairy products, wheat, egg, and soy are recognized as the most common triggers for EoE. A person with EoE may have one or more foods triggering their EoE. Once the causative food(s) is (are) identified and removed from a persons diet, esophageal inflammation and symptoms generally improve in a few weeks.

  Eosinophilic Esophagitis (EoE) is believed to be caused by a combination of factors. The immune system’s overreaction to allergens and certain genetic factors play significant roles in the development of this condition. […] The immune system’s overreaction to allergens is a key factor in the development of EoE. When an allergen is detected, the body produces Immunoglobulin E (IgE), which triggers an immune response. This response can lead to the accumulation of eosinophils in the esophagus. Allergens that may trigger this response include certain foods, environmental allergens like dust mites, and pollen. Oral Allergy Syndrome (OAS), a condition where certain food proteins cross-react with pollen allergens, could also be a potential trigger. […] EoE is also influenced by genetic factors. Some individuals have a family history of EoE, suggesting a hereditary predisposition. Moreover, certain genes have been associated with EoE, indicating a genetic component to the disease. These genes are involved in the regulation of the immune response, particularly the function and accumulation of eosinophils. Research is ongoing to better understand the interplay of these factors in EoE.

  While its pathogenesis isnt clear, studies have found several genes that are overexpressed in EoE patients. One of particular interest is the calpain-14 gene (CAPN14) because it is specifically expressed in the surface layer of the esophagus where food first comes in contact with the esophagus. […] Like other atopic conditions, EoE also appears to be associated with T cell immune responses. Cytokines chemical messengers released by the T cellsare hypothesized to play an important role in the activation and recruitment of eosinophils in the esophagus.

  What causes eosinophilic esophagitis (EoE)? […] Research into how one develops EoE is still being studied. It is believed to be triggered by abnormal type 2 immune response to food and likely aeroallergens (airborne substances or inhalants such as pollens, spores, and other particles that cause allergic disorders). Type 2 immune system response refers to the type of immune system activation occurring in the body. Type 2 immune response is seen in allergic disorders like asthma. But the development of this disorder is not simply an allergic reaction. It is a complex interaction between genetics and antigen triggers in the environment. […] Atopic (allergic disorders) conditions are common to see in those with EoE. More than 75% of people with EoE have food allergies, atopic dermatitis, allergic rhinitis, nasal polyps, and/or asthma. Therefore, individuals with a personal history of atopy, frequent dysphagia and/or altered eating habits should talk to their doctor about being evaluated for the diagnosis of EoE.

The reaction may occur as follows: […] The lining of your esophagus reacts to allergens, such as food or pollen. […] The eosinophils multiply in your esophagus and produce a protein that causes inflammation. […] Inflammation can lead to scarring, narrowing and formation of excessive fibrous tissue in the lining of your esophagus.

  Potential triggers like changes in food production methods, genetic modification of crops, chemical additives, food processing techniques, and environmental pollutants have been proposed as possible factors. […] The decreasing frequency of Helicobacter pylori infection, which was previously very common, may have removed a protective effect against some allergic diseases. […] Rising rates of gastroesophageal reflux disease (GERD) could compromise the esophageal barrier, allowing food allergens to stimulate the immune system and contribute to EoE development. […] Increased use of antacids, especially early in life, may alter the oesophageal microbiome and influence the risk of subsequent food allergies like EoE.

• #101 What Is Eosinophilic Esophagitis (EoE)? Symptoms, Causes, Diagnosis, and Treatment

  https://www.everydayhealth.com/eosinophilic-esophagitis/

  The exact cause of EoE isn’t known, but experts believe the condition is usually triggered by the body’s immune response to certain foods. Many people with EoE report having food allergies, and about half also suffer from seasonal allergies or asthma. […] But people who don’t have food allergies or asthma can also suffer from EoE. Researchers at the American College of Allergy, Asthma Immunology believe that both environmental and genetic factors play a role. Research shows that there are genetic predispositions to EoE that are being more closely examined. […] Experts aren’t exactly sure what might contribute to a rising number of EoE cases, but according to Harvard Health Publishing, some possible theories include: The typical Western diet could alter the populations microbiome. Environmental factors, such as chemical additives, genetic crop modifications, pollutants, or food processing, may be contributors. Fewer Helicobacter pylori (H. pylori) infections (a common cause of peptic ulcers) may mean less protection against some allergic diseases. More cases of GERD could correlate with more instances of EoE. The idea is acid reflux might break the barrier of the esophagus and allow food allergens to stimulate the immune system. Increased use of acid-suppressing drugs, especially early in life, might change the microbes in the esophagus or raise a person’s risk of developing a food allergy.

[…] Avoiding allergens can often reverse the disease process of EoE. Successful implementation of a suitable dietary plan can be made easier with assistance from a dietitian. […] There is a role for acid suppression in patients with EoE, but it is not a curative measure. The already inflamed oesophagus in EoE is predisposed to injury and hypersensitive to physiologic levels of acid exposure. PPI therapy can aid healing and improve symptoms, but it fails to induce total histological remission.

  Population studies show a steady rise in the incidence (6.6 per 100,000 person-years) and prevalence (34 per 100,000) of Eosinophilic Esophagitis (EoE) in children. […] The etiology of EoE is not completely understood, but like other atopic diseases, it appears to result from an interplay between genetics and environment. […] The marked increase in the diagnosis of EoE along with data from twin studies indicate that environmental factors likely play a large role in the etiology of EoE. […] Environmental factors that are reliably associated with EoE include: Food allergens Milk is the most common food trigger of EoE (followed by wheat, egg, and soy) […] Antibiotics in infancy Similar to observational studies for other atopic conditions, antibiotic use in infancy is correlated with a higher risk of EoE, but causality has not been established.

  The exact cause of EoE isn’t known, but experts believe the condition is usually triggered by the body’s immune response to certain foods. Many people with EoE report having food allergies, and about half also suffer from seasonal allergies or asthma. […] But people who don’t have food allergies or asthma can also suffer from EoE. Researchers at the American College of Allergy, Asthma Immunology believe that both environmental and genetic factors play a role. Research shows that there are genetic predispositions to EoE that are being more closely examined. […] Experts aren’t exactly sure what might contribute to a rising number of EoE cases, but according to Harvard Health Publishing, some possible theories include: The typical Western diet could alter the populations microbiome. Environmental factors, such as chemical additives, genetic crop modifications, pollutants, or food processing, may be contributors. Fewer Helicobacter pylori (H. pylori) infections (a common cause of peptic ulcers) may mean less protection against some allergic diseases. More cases of GERD could correlate with more instances of EoE. The idea is acid reflux might break the barrier of the esophagus and allow food allergens to stimulate the immune system. Increased use of acid-suppressing drugs, especially early in life, might change the microbes in the esophagus or raise a person’s risk of developing a food allergy.

  Eosinophilic oesophagitis (EoE) is a chronic inflammatory disorder of the oesophagus that leads to oesophageal dysfunction and symptoms including dysphagia and heartburn. […] The current understanding of EoE pathogenesis is limited. It is a chronic disease that involves an interrelationship between genetic and environmental factors. Alteration in the hosts immune response manifests as an allergic oesophageal reaction to food-based proteins consumed in the diet. Antigens from various foods (eg milk, wheat, soy, eggs and seafood) have been implicated. […] The prevalence of EoE in Australia is estimated to be 1 in 100 adults and 1 in 10,000 children. Its prevalence appears to be rising, and studies have shown that detection is growing at rates not accounted for by improved awareness alone. The hygiene hypothesis has been suggested as a cause.

The shifts in EoE epidemiology over the past two decades, with a steadily increasing incidence and prevalence, are too fast for a genetic cause and argue instead for an environmental etiology. […] Do we know what causes EoE? The simple answer is no. We do not know why an individual patient develops EoE at a certain time. In the context of the rapidly evolving epidemiology of EoE, with increasing incidence and prevalence, the current hypothesis is that individuals with a genetic predisposition must have an appropriate environmental exposure. In some cases these might be food or aeroallergens. However, the complex interactions between allergic, genetic, and environmental pathways and exposures require additional investigation.
