Treatment of eosinophilic esophagitis


From a recent review:

If left untreated, eosinophilic inflammation induces fibrosis, angiogenesis and stricture formation, resulting finally in a so called remodelling with structural and functional damage of the organ. In addition, patients with untreated EoE are permanently at risk of experiencing food impactions...Avoidance of food allergens by elimination diets as well as anti-inflammatory drugs have both the ability to achieve these goals. Among the pharmacological options, only corticosteroids have documented efficacy, whereas alternatives have shown rather disappointing results or are still under evaluation. Of note, swallowed topical corticosteroids are at least as efficient as systemically administered corticosteroids but have fewer side effects. As such topical corticosteroids are widely used as first-line drug in the treatment of EoE, even though this compound is currently not approved for this indication by regulatory authorities.

Unfortunately, complete resolution of symptoms can be achieved with swallowed topical corticosteroids only in approximately 70% of patients despite appropriate dosing and despite correct administration of these compounds. Control of inflammation is even harder to achieve, as only in approximately 50% of patients tissue eosinophilia disappears completely under this anti-inflammatory medication. For this group of “difficult to treat” patients, therapeutic alternatives are urgently needed.
