Eosinophilic esophagitis (EE) is an allergic inflammatory disease characterized by the accumulation of eosinophils in the esophageal wall. It is recognized as a clinical disorder that may manifest as dysphagia (difficulty swallowing), chest pain, vomiting, and other digestive symptoms. EE can occur in any age group, but is most often diagnosed in children and young adults. Eosinophilic esophagitis can be associated with various allergic conditions such as rhinitis, asthma, and eczema, indicating its multifactorial nature. Acute and chronic forms of the disease require different approaches to therapy, making it a significant topic in gastroenterology practice.
History of the disease and interesting historical facts
Eosinophilic esophagitis was first described in the early 20th century, but has become more widely known in clinical practice since the 1990s. The relevance of the disease is increasing due to the increase in cases of allergic diseases in general. An interesting fact is that EE was initially considered a rare disease, but with the development of endoscopic diagnostic methods and growing interest in allergology, cases of the disease began to be recorded more and more often. Records of EE began to appear in scientific papers, confirming its connection with allergic pathologies and food factors.
Epidemiology
Statistics show that the prevalence of eosinophilic esophagitis is increasing, reaching, according to some studies, 5-10 cases per 100,000 people per year. According to recent studies, EE is more often diagnosed in men and young children, but data show an increase in cases among older people. This is due not only to improved diagnostics, but also to an increase in environmental allergens, changes in diet and lifestyle. According to the WHO, in some countries, the incidence of EE is increasing in parallel with the rise of other allergic diseases, such as asthma.
Genetic predisposition to this disease
Studies show that genetic predisposition may play an important role in the development of eosinophilic esophagitis. In particular, certain alleles of the HLA (histocompatibility) gene are associated with increased susceptibility to the disease. Experimental data show that some mutations in genes responsible for the immune response and inflammation may also contribute to the accumulation of eosinophils in the esophagus. In particular, polymorphisms in the IL-4 and IL-13 genes involved in the regulation of allergic reactions may be associated with the development of EE.
Risk factors for the development of this disease
There are a number of risk factors that contribute to the development of eosinophilic esophagitis:
- Allergic diseases: asthma, eczema, allergic rhinitis.
- Food allergy: intolerance to certain types of food.
- Environmental factors: environmental pollution, smoking.
- Genetic predisposition: presence of cases of the disease in the family.
- Age characteristics: more common in children and young people.
These factors risk increasing the incidence of EE, but not all individuals with risk factors will necessarily develop the disease, highlighting the importance of a comprehensive approach to diagnosis and treatment.
Diagnosis of this disease
Diagnosis of eosinophilic esophagitis often requires a multidisciplinary approach and includes the following steps:
- Main symptoms: difficulty swallowing, chest pain, vomiting, reflux.
- Laboratory tests: complete blood count to detect eosinophilia, allergy tests.
- Radiological examinations: X-ray with contrast to assess the condition of the esophagus.
- Endoscopy and biopsy: allows for a visual assessment of the condition of the esophageal wall and a histological examination for the presence of eosinophils.
- Differential diagnosis: exclusion of other diseases such as gastroesophageal reflux disease and infectious lesions.
Improved diagnostics significantly improve treatment outcomes and quality of life for patients with eosinophilic esophagitis.
Treatment
Treatment of eosinophilic esophagitis requires a comprehensive approach and may include the following measures:
- General treatment: dietary changes, elimination of allergenic foods, and introduction of new eating habits.
- Pharmacological treatment: use of topical corticosteroids to reduce the inflammatory response.
- Surgical treatment: In rare cases, surgery may be required to correct stenosis and other complications.
- Other treatments: allergen elimination therapy, use of antihistamines.
The effectiveness of treatment depends on the individual characteristics of the patient and the severity of the disease. Modern treatment methods have shifted towards more invasive and highly effective therapies.
List of medications used to treat this disease
The following groups of drugs are widely used in the treatment of eosinophilic esophagitis:
- Topical corticosteroids: inhalers and sprays.
- Antihistamines: Treatment of EE-related allergies.
- Immunosuppressants: use in patients with severe forms of the disease.
- Probiotics: as an additional means for immunostimulation and improving the condition of the esophageal microflora.
These drugs can have a significant impact on improving quality of life and reducing symptoms.
Disease monitoring
Monitoring of eosinophilic esophagitis involves regular follow-up examinations and assessment of response to treatment. This includes:
- Control stages: regular visits to the doctor to monitor the condition and dynamics of the disease.
- Prognosis: With timely diagnosis and treatment, the prognosis is favorable, daily symptoms can be significantly reduced.
- Complications: need to be monitored for possible complications such as esophageal stenosis and deterioration in quality of life.
Constant monitoring and adjustment of treatment can prevent disease progression and improve the quality of life of patients.
Age-related features of the disease
Eosinophilic esophagitis may present differently in different age groups:
- Children: Symptoms related to dysphagia and allergies are often recorded. Developmental delays may also be noticeable.
- Adolescents and young adults: cases of stenosis and more severe symptoms such as vomiting and eating difficulties.
- Adults: Symptoms may be less severe, but there is an increased risk of chronic complications.
- Elderly people: mixed pathology and involvement of other organs are often observed.
These features may require different approaches to diagnosis and treatment.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov advises patients with eosinophilic esophagitis:
— Do not delay a visit to the doctor if you have symptoms of dysphagia or chest pain. Early diagnosis and treatment significantly improve the prognosis.
— Keep a food diary to track possible triggers and improve your healing conditions.
— Maintain a healthy lifestyle: a balanced diet, avoiding allergens and stress, which can help manage symptoms.
— Regularly discuss the results of treatment with your doctor and monitor changes in your condition, which will allow you to adjust therapy if necessary.
