Eosinophilic oesophagitis (EO) is an increasingly recognised chronic, relapsing inflammatory condition of the oesophagus. There has been a mini-epidemic of EO in the last decade. The incidence of this condition is higher in children and is commoner in males. There is either a family or personal history of atopic conditions present in a significant number of patients and can also be familial in up to 10%. The classical symptom in an adult is chronic, intermittent solid-food dysphagia and food impaction, often necessitating emergency endoscopic removal. Despite the history of dysphagia for a number of years, patients remain well with no weight loss, which can mislead clinicians to diagnose a functional problem with a resulting delay in the diagnosis. There are various endoscopic features of EO; commonly multiple rings and linear furrows, though these can be subtle and the mucosa may be macroscopically normal. The hallmark of this condition is the histological presence of > or =15 eosinophils/high power field (HPF) in the oesophageal mucosa. Therapeutic options include avoidance of dietary allergens, topical or systemic steroids, Montelukast, Mepolizumab (anti-IL-5 antibody) and endoscopic dilation of strictures unresponsive to medical therapy.

Eosinophilic esophagitis is characterized by dense infiltration of the esophageal epithelium with eosinophils, typically accompanied by dysphagia. Effective therapies include the use of topical and systemic steroids as well as elimination diets. No previous reports have described the use of montelukast in the management of pediatric eosinophilic esophagitis. We retrospectively reviewed the charts of all patients with eosinophilic esophagitis followed in our pediatric center between 2000 and 2009. Those treated with montelukast were studied in detail. Study outcome was clinical response rate, defined by symptom (not histologic) improvement. Twenty-one patients with eosinophilic esophagitis were identified. Eight patients were maintained on montelukast (range 4-10 mg daily) after confirming the diagnosis of eosinophilic esophagitis histologically and failing to respond to a trial of proton pump inhibitor therapy. Three of eight patients had a clinical response (one had complete response and two with partial response) that could be attributed to montelukast. Four other patients responded clinically, but other therapies were concomitantly implemented. No side effects were reported with montelukast treatment with a mean follow-up duration of 32 months. Five patients had remained on montelukast therapy at the time of the final follow-up. Montelukast has minimal risk of adverse reactions compared with steroid therapy and may offer clinical relief in a small subset of children with eosinophilic esophagitis. Histologic response could not be verified in this study. Prospective studies, using higher montelukast doses, may potentially play a role and should be considered for future investigation.
