A Randomized Double Blind Placebo Controlled Study of the Effect of Swallowed Beclomethasone Dipropionate on Inflammatory Markers in Adult Patients With Eosinophilic Esophagitis

The investigators hypothesize that swallowed beclomethasone leads not only to improvement of symptoms and decreased number of eosinophils in esophageal mucosa, but also to a decrease in other markers of tissue inflammation like mast cells, CD4+ T lymphocytes, IL4, IL-5, IL13, GM-CSF and TGF-beta as well as serum ultra-sensitive C-Reactive Protein (CRP). The investigators aim to characterize the response of esophageal inflammation to swallowed topical glucocorticoids, and identify biomarkers to assess response to treatment.

This research will elucidate the effect of treatment with beclomethasone on various inflammatory markers in EoE, which is currently not well-understood. This work will explore the pathophysiology of EoE, and has the potential to find a non-invasive biomarker such as high-sensitivity CRP that can be used to monitor the response to treatment.

EoE is an increasingly recognized clinicopathological diagnosis, characterized by a marked accumulation of eosinophils in the esophageal mucosa.The presence of eosinophils and association of the disease with food allergy and allergic rhinitis suggests an atopic disease. Allergic diseases are associated with T-helper 2 lymphocytes (TH2) predominant cytokines such as interleukins 4, 5, 13 (IL4, IL5, IL13), which are known to induce IgE synthesis and promote eosinophilic infiltration. Granulocyte-Monocyte Colony Stimulating Factor (GM-CSF) and Transforming Growth Factor (TGF) - beta are cytokines which are associated with many eosinophilic disorders. Swallowed steroid is a conventional treatment that has been shown to improve symptoms and decrease number of eosinophils in the esophagus in patients with EoE. However, no studies have investigated the effect of swallowed steroid on markers of TH2 inflammation in adult patients with EoE.Currently repeated endoscopic biopsy of esophagus is the only tool to monitor response to treatment. Serum ultra- sensitive CRP is a non-invasive marker of inflammation in cardiovascular and gastrointestinal disorders. This study proposes to investigate the correlation of disease activity with this potential marker of inflammation in adult patients with EoE which has not been previously studied.

Specific Aim #1: To measure the baseline level of a proposed panel of inflammatory markers: serum ultra-sensitive CRP and peripheral eosinophils, as well as tissue eosinophils, mast cells, CD4 cells, IL-4, IL-5, IL-13, GM-CSF and TGF-beta in the esophagus in adult patients with eosinophilic esophagitis.

Specific Aim #2: To determine the impact of 8 week course of treatment with swallowed beclomethasone on the levels of the inflammatory markers measured in Specific Aim #1.

Specific Aim #3: To determine the correlation between the levels of the proposed panel of inflammatory markers and symptoms of EoE before and after 8 weeks of treatment with swallowed beclomethasone.
