Top Three Treatments for Eosinophilic Esophagitis Dysphagia Relief

Eosinophilic esophagitis (EoE) presents a significant clinical challenge, with dysphagia being the most common and debilitating symptom. The underlying pathology involves an allergic inflammatory response within the esophageal mucosa, leading to fibrosis and stricture formation.¹ Management strategies aim to control this inflammation, thereby alleviating symptoms and preventing disease progression. The current evidence supports three main therapeutic approaches: proton pump inhibitors (PPIs), topical corticosteroids, and dietary elimination.²

Pharmacological and Dietary Interventions for EoE

Proton pump inhibitors (PPIs) are often the initial therapeutic choice for EoE. While traditionally used for acid suppression, PPIs have demonstrated anti-inflammatory effects in the esophageal mucosa, independent of their acid-reducing properties.³ Studies indicate that PPIs can induce histological remission (defined as fewer than 15 eosinophils per high-power field) in approximately 50% of adult EoE patients.⁴ Symptomatic improvement, including relief from dysphagia, is observed in a similar proportion of patients. The mechanism is thought to involve inhibition of eotaxin-3 expression and modulation of tight junction proteins.³

Topical corticosteroids, such as fluticasone propionate and budesonide, are highly effective in treating EoE. These agents are administered orally, typically as a swallowed slurry or spray, allowing direct contact with the esophageal mucosa.⁵ Fluticasone propionate, delivered via a metered-dose inhaler and swallowed, has shown histological remission rates ranging from 70% to 80% in both adult and paediatric populations.⁶ Budesonide, often formulated as an oral viscous slurry, demonstrates similar efficacy, with remission rates also in the 70-80% range.⁷ Both agents significantly improve dysphagia and other EoE symptoms. The main adverse event associated with topical corticosteroids is oral candidiasis, which occurs in approximately 5-10% of patients and is typically managed with antifungal therapy.^6,7

Dietary elimination therapy involves identifying and removing specific food allergens that trigger the inflammatory response in EoE. The most common approach is the six-food elimination diet (SFED), which removes milk, wheat, soy, egg, peanut/tree nuts, and fish/shellfish.⁸ This broad elimination diet has shown high efficacy, with histological remission rates of 70-75%.⁹ However, the SFED is restrictive and requires subsequent reintroduction of foods with endoscopic biopsies to identify specific triggers, which can be burdensome for patients.⁸ A more targeted approach, such as allergy testing-directed elimination, has lower efficacy (approximately 40-50% remission) but is less restrictive.¹⁰ Elemental diets, consisting of amino acid-based formulas, are the most effective dietary therapy, achieving remission in over 90% of patients, but are generally reserved for severe cases or those unresponsive to other therapies due to their palatability and cost.¹¹

The choice of therapy often depends on patient preference, disease severity, and response to initial treatment. While PPIs offer a convenient first-line option, topical corticosteroids provide higher remission rates. Dietary therapy, particularly SFED, is highly effective but demands significant patient adherence and diagnostic follow-up. Combination therapies are also employed in refractory cases.¹²
