Eosinophilic enteropathy (EE) is a rare disorder characterized by elevated levels of eosinophils in the intestinal wall and their inflammatory properties, which in turn can lead to a variety of digestive symptoms. The disease can present with both acute and chronic symptoms, including abdominal pain, intestinal disorders, and systemic allergy symptoms. Eosinophilic enteropathy typically affects young and middle-aged adults, but can also occur in children. The pathogenesis of this condition is not fully understood, although it is assumed that food allergens, as well as some infectious and environmental factors, may be one of its triggers. This multifactorial approach to understanding the disease suggests the need for further clinical research and understanding the mechanisms of its development.
History of the disease and interesting historical facts
Eosinophilic enteropathy was first described in the medical literature in the 1970s, when physicians noticed unusual cases of eosinophilic infiltrate in the intestinal wall. Although the disease was known, its clinical characteristics remained vague, leading to an underestimation of its prevalence. Over time, several large studies have demonstrated that parasitic infections and allergic reactions have a significant impact on the development of EE. Interestingly, in some cases, eosinophilic enteropathy has been associated with other diseases such as atopic dermatitis and asthma, suggesting a broader allergic background in patients. In recent decades, advances in imaging and biopsy techniques have made it possible to more accurately diagnose this disease, which has also led to a better understanding of the disease and the definition of appropriate therapeutic strategies.
Epidemiology (statistics of disease occurrence)
Eosinophilic enteropathy is a rare disease, and its exact prevalence remains unknown due to underdiagnosis and a variety of symptoms. However, studies show that EE occurs in 0.3-1% of all intestinal diseases. The incidence of the disease varies by region, which may be due to differences in ecology and nutrition. In particular, diseases are more common in countries with high rates of allergies and autoimmune disorders. According to 2020 data, the combination of eosinophilic enteropathy with other allergic conditions is observed in 25-50% patients, which once again emphasizes the importance of an integrated approach to diagnosis and treatment.
Genetic predisposition to this disease
Data on genetic predisposition to eosinophilic enteropathy are limited, but there are studies that support the involvement of a number of genes and mutations in the pathogenesis of the disease. In particular, genetic variations have been identified in regions associated with the regulation of the immune response, including genes involved in the synthesis of interleukins and other cytokines that play a key role in eosinophilic activity. Some researchers have indicated a link between eosinophilic enteropathy and certain polymorphisms in genes responsible for allergic reactions, such as the IL-4 and IL-5 genes. These findings highlight the importance of genetic predisposition and its interaction with the environment, which may contribute to the development of this disease.
Risk factors for the development of this disease
There are several risk factors that contribute to the development of eosinophilic enteropathy, which can be divided into physical and chemical. Physical factors include:
- Allergic reactions to foods such as milk, eggs, nuts.
- Infectious agents such as parasites, which can cause recurrent intestinal inflammation.
- Associated allergic diseases such as asthma and rhinitis.
Chemical factors may include:
- Exposure to toxic substances or food additives that cause disturbances in the immune response.
- Certain medications may cause side effects and allergic reactions in susceptible patients.
It is important to note that exposure to these factors can lead to the development of the disease both in previously healthy people and in those who already have an increased predisposition to allergic conditions.
Diagnosis of this disease
Diagnosis of eosinophilic enteropathy requires a comprehensive approach and includes several stages. The main symptoms of the disease may vary, but most often patients complain of:
- Abdominal pain, usually localized in the lower parts.
- Diarrhea with mucus or blood.
- Nausea and vomiting.
- Loss of appetite and weight loss.
Laboratory tests are an important part of the diagnosis. This includes blood tests that show an increased number of eosinophils. Radiological examinations such as ultrasound or CT of the abdomen can help in assessing the condition of the intestine. An important part of the diagnosis is gastroscopy followed by biopsy to confirm the diagnosis; it is the microscopic examination of the biopsy for eosinophilic invasion that allows the final diagnosis to be made. Differential diagnosis with other conditions such as ulcerative colitis or Crohn's disease must also be made, as symptoms may overlap.
Treatment
Treatment of eosinophilic enteropathy depends on the severity of the disease and the individual characteristics of the patient. General treatment often includes a strict diet with the exclusion of potential allergens, which can lead to a reduction in symptoms. Pharmacological treatment is based on the use of corticosteroids, which reduce the inflammatory response, and antihistamines. In severe cases, immunosuppressants may be used. Surgical treatment may be required in rare cases when complications arise, such as intestinal stenosis or tumors not associated with inflammation. Alternative treatments, such as probiotics or acupuncture, have not yet received sufficient scientific support, but can be used as an adjunct to the main therapy.
List of medications used to treat this disease
The main groups of drugs used to treat eosinophilic enteropathy include:
- Corticosteroids (prednisolone, budesonide).
- Antihistamines (cetirizine, loratadine).
- Immunosuppressants (azathioprine, 6-mercaptopurine).
- Biological therapy (mepolizumab, reslizumab) in case of severe course.
- Probiotics to maintain intestinal microflora.
These drugs can be used both in monotherapy and in combination therapy, which is selected individually for each patient.
Disease monitoring
Monitoring of eosinophilic enteropathy is an important part of comprehensive treatment and includes regular assessment of the patient's condition. Control steps should include:
- Periodic laboratory tests to monitor the level of eosinophils in the blood.
- Endoscopic examinations to visually assess the condition of the intestines.
- Assessing symptoms to determine the effectiveness of therapy.
The prognosis for patients with eosinophilic enteropathy varies, but with adequate therapy, most patients experience significant improvement. Potential complications may include the development of intestinal stenosis, passage of food through the intestines, and other serious gastrointestinal disorders.
Age-related features of the disease
Eosinophilic enteropathy can manifest itself in different age groups, although it is more often diagnosed in young people and children. In children, the disease usually manifests itself with more acute symptoms, while in adults, chronic manifestations with periodic exacerbations are often observed. Adult patients may associate their condition with previous allergic reactions. In mirror reflection, in older people, the manifestations of eosinophilic enteropathy may be less pronounced, which often complicates diagnosis. Taking into account the different age groups, a comprehensive individual approach to treatment and monitoring of the patient's condition is necessary.
