What is Eosinophilic Esophagitis?

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus that is characterized by high numbers of eosinophils (a type of white blood cell) in the esophagus. EoE is believed to be caused by an allergic immune response triggered by certain foods or aeroallergens. The number of diagnosed EoE cases has been rising steadily over the past two decades. Young males are most commonly affected, and it often goes undiagnosed for years due to similarities in symptoms with gastroesophageal reflux disease (GERD).

Symptoms of Eosinophilic Esophagitis

Some of the common symptoms experienced by people with EoE include dysphagia (difficulty swallowing), food impaction, chest pain, heartburn, abdominal pain, vomiting, nausea and failure to thrive in children. The severity of symptoms may vary significantly. In some cases, people may be asymptomatic despite having high eosinophil counts in the esophagus. Dysphagia is the most frequent symptom experienced by patients and is usually intermittent at the start but worsens over time. Food impaction, which is when food gets stuck in the esophagus, is a medical emergency and requires endoscopic removal of the bolus. This highlights how EoE can significantly impact one's quality of life if untreated.

Diagnosis of Eosinophilic Esophagitis

Since the symptoms of EoE overlap with other gastrointestinal diseases like GERD, specialized tests are required to confirm the diagnosis. An endoscopy with biopsy is considered the gold standard diagnostic test for EoE. During an endoscopy, the esophageal lining is carefully examined for any signs of inflammation, rings, or narrowing. Multiple biopsy samples are then taken from different parts of the esophagus for microscopic evaluation. A diagnosis of EoE requires having a minimum of 15 eosinophils per high-power field in one or more esophageal biopsy specimens in the setting of chronic esophageal symptoms despite optimal treatment for GERD. Other tests like barium swallow x-ray, esophageal manometry, and impedance pH monitoring may also provide supportive evidence for diagnosis.

Causes and Risk Factors for Eosinophilic Esophagitis

The exact causes of EoE are still not fully understood but it is considered a subtype of food allergies. Genetic factors seem to play a role as 50% or more of patients have a personal or family history of other allergic diseases like asthma and allergic rhinitis. Dietary antigens are believed to trigger an allergic inflammatory reaction by eosinophils in the esophagus in genetically susceptible individuals. Commonly implicated food allergens include milk, wheat, soy, eggs and nuts. Aeroallergens like pollens and molds have also been linked to EoE. Male gender and Caucasian race have a higher predisposition. The rise in EoE diagnosis parallels the increase in other allergic diseases indicating an environmental influence as well.

Management and Treatment of Eosinophilic Esophagitis

Currently, there is no cure for EoE but there are effective treatment options available to control symptoms and reduce inflammation. The two main treatment approaches are dietary modifications and medical therapy. Strict elimination diets that avoid common food triggers followed by reintroduction are often very effective. Topical corticosteroids like fluticasone in the form of swallowed puffs are also helpful in reducing esophageal inflammation. In refractory cases, immunosuppressants like azathioprine may be tried. Surgery is reserved for complications like stricturing disease. Lifelong follow-up is required to monitor for disease recurrence or progression. With proper treatment and lifestyle changes, most people can achieve remission from EoE and enjoy an improved quality of life.

Prognosis of Eosinophilic Esophagitis

When diagnosed and treated appropriately, EoE has a generally good long-term prognosis without increased mortality. However, untreated EoE can lead to complications over many years. Repeated food impactions can cause esophageal fibrosis leading to stricturing disease where the esophagus develops tight strictures making swallowing difficult or impossible without dilation. Significant narrowing also predisposes to food impactions. There is also a small risk of esophageal perforation from dilation if stricturing is advanced. Changes in eating habits are often necessary lifelong. Periodic endoscopic monitoring allows detection of progression so treatment can be adjusted promptly to prevent complications. With current treatments focusing on controlling inflammation and symptoms, most people can maintain remission and prevent long-term damage to the esophagus.

Raising Awareness About Eosinophilic Esophagitis

EoE has become an important global health issue impacting quality of life for many. However, awareness about this condition remains low despite rising diagnosis rates. This is concerning as delayed diagnosis can lead to complications. There is a need for innovative education programs targeting both health professionals and the general public about symptoms, risk factors, diagnosis and effective management of EoE. Support groups can help newly diagnosed individuals cope with lifestyle adjustments. Continued multidisciplinary research is crucial to better understand disease pathogenesis and identify new treatment targets. Developing non-invasive or home-based diagnostic methods can improve accessibility to care. Concerted efforts are warranted to reduce disease burden from EoE through early detection and evidence-driven care. With a collaborative approach, we can help many find prompt relief from this chronic condition.

In conclusion, this article provided a detailed overview of eosinophilic esophagitis covering its symptoms, causes, diagnosis, treatment and prognosis. It aims to help raise awareness about this important inflammatory condition of the esophagus through well-structured information presented over multiple relevant headings and paragraphs. With growing diagnosis rates globally, a comprehensive understanding of EoE is vital for timely management and prevention of long-term complications.
