Eosinophilic esophagitis (EoE) is a newly recognized chronic disease that can be associated with food allergies. It is increasingly being diagnosed in children and adults. EoE is characterized by inflammation and accumulation of a specific type of immune cell, called an eosinophil, in the esophagus. Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body’s immune response. They can also build up and cause inflammation. Normally your blood doesn’t have a large number of eosinophils. Your body may produce more of them in response to, allergic disorders, skin conditions, parasitic and fungal infection, autoimmune diseases, some cancers, and bone marrow disorders. In some conditions, the eosinophils can move outside the bloodstream and build up in organs and tissues. Symptoms of EoE include nausea, vomiting, and abdominal pain after eating. A person may also have symptoms that resemble acid reflux from the stomach. In older children and adults, it can cause more severe symptoms, such as difficulty swallowing solid food or solid food sticking in the esophagus for more than a few minutes. In infants, this disease may be associated with failure to thrive. In some situations, avoiding certain food allergens will be an effective treatment for EoE.
Eosinophilic gastroenteritis occurs when certain white blood cells known as eosinophils get into the digestive tract and cause damage. Symptoms of eosinophilic gastroenteritis usually start in adulthood and may include stomach pain, nausea, vomiting, and the inability to absorb nutrients from food. Sometimes, a blockage in the intestines occurs. In most people, symptoms occur from time to time and may go away completely with treatment. The exact cause of eosinophilic gastroenteritis is unknown, but it may be due to an abnormal response of the immune system to food allergies. Diagnosis is based on the symptoms, a clinical exam, laboratory tests, and by excluding other more common conditions. Treatment is focused on managing the symptoms and includes diet and medication.[1][2]
Types of Eosinophilic Esophagitis (EoE):
EoE can be categorized into two main types:
- Primary EoE: This type occurs independently and is not associated with other health conditions.
- Secondary EoE: Secondary EoE is linked to other health issues, such as gastroesophageal reflux disease (GERD) or allergic conditions.
Causes of Eosinophilic Esophagitis (EoE):
- Allergies: Allergic reactions to foods, pollen, or environmental allergens can trigger EoE.
- Genetics: EoE may run in families, suggesting a genetic component.
- GERD: Gastroesophageal reflux disease can lead to EoE in some cases.
- Food Sensitivities: Certain foods, especially common allergens like milk, wheat, and eggs, can cause EoE.
- Environmental Allergens: Pollen, dust mites, and mold can exacerbate EoE symptoms.
- Eating Too Quickly: Swallowing food too fast without proper chewing can contribute to EoE.
- Stress: Psychological stress can worsen EoE symptoms.
- Smoking: Smoking may increase the risk of EoE.
- Autoimmune Conditions: Some autoimmune diseases are associated with EoE.
- Medications: Certain medications, like non-steroidal anti-inflammatory drugs (NSAIDs), can trigger EoE.
- Infections: Viral or bacterial infections may lead to EoE in some cases.
- Chemical Irritants: Exposure to irritants like cleaning chemicals may contribute to EoE.
- Obesity: Obesity is linked to an increased risk of EoE.
- Childhood Eating Habits: Early introduction of solid foods in infants may be a risk factor.
- Lack of Breastfeeding: Not being breastfed as an infant could be associated with EoE.
- Environmental Toxins: Exposure to environmental toxins may play a role.
- Seasonal Changes: EoE symptoms can worsen during specific seasons.
- Eating Late at Night: Consuming food right before bedtime can exacerbate EoE.
- Alcohol Consumption: Excessive alcohol intake may contribute to EoE.
- Lack of Physical Activity: A sedentary lifestyle may increase the risk of EoE.
Symptoms of Eosinophilic Esophagitis (EoE):
- Dysphagia: Difficulty swallowing or the sensation of food getting stuck in the throat.
- Food Impaction: Episodes where food becomes lodged in the esophagus.
- Heartburn: A burning sensation in the chest or upper abdomen.
- Chest Pain: Discomfort or pain in the chest area.
- Regurgitation: The return of partially digested food into the mouth.
- Nausea: Feeling queasy or the urge to vomit.
- Vomiting: Forceful expulsion of stomach contents.
- Weight Loss: Unintentional weight loss due to difficulty eating.
- Failure to Thrive: Poor growth and development in children.
- Abdominal Pain: Discomfort in the abdominal area.
- Difficulty Sleeping: Sleep disturbances due to EoE symptoms.
- Mouth Sores: Painful sores in the mouth.
- Food Aversions: Avoiding certain foods due to fear of symptoms.
- Chronic Cough: A persistent cough that doesn’t respond to usual treatments.
- Hoarseness: Changes in the voice, making it raspy or weak.
- Throat Clearing: Frequent clearing of the throat.
- Feeling Full Quickly: Satiety shortly after starting a meal.
- Malnutrition: A lack of essential nutrients due to difficulty eating.
- Esophageal Rings: Narrow rings forming in the esophagus.
- Esophageal Strictures: Narrowing of the esophagus due to scarring.
Diagnostic Tests for Eosinophilic Esophagitis (EoE):
- Endoscopy: A flexible tube with a camera is used to examine the esophagus.
- Biopsy: Tissue samples are taken during endoscopy to check for eosinophilic inflammation.
