montelukast and Deglutition-Disorders

Eosinophilic oesophagitis (EO) is an immune/antigen mediated, chronic, relapsing disease characterised by dysphagia, food bolus impaction and a dense oesophageal eosinophilic infiltrate. Characteristic endoscopic features include corrugated rings, linear furrows and white exudates, but none are diagnostic. Despite its increasing prevalence, EO remains underdiagnosed. There is a strong association with other atopic conditions. Symptoms, histology and endoscopic findings can overlap with gastro-oesophageal reflux disease. Currently endoscopy and oesophageal biopsies are the investigation of choice. Oesophageal physiology studies, endoscopic ultrasound, impedance planimetry and serology may have a role in the diagnosis and monitoring of response to therapy. Acid reducing medication is advocated as first line or adjuvant therapy. Dietary therapy is comprised of elimination diets or can be guided by allergen assessment. In adults, topical corticosteroids are the mainstay of therapy. Endoscopic dilatation is safe and effective for the treatment of non-responsive strictures. Other therapeutic options (immunomodulators, biological agents, leukotriene receptor antagonists) are under investigation.

Eosinophilic esophagitis (EE) is a relatively new, chronic, TH 2-type allergic inflammation of the esophagus. EE occurs more frequently in men. Allergic diseases such as asthma or atopic dermatitis are present in 50-70 % of patients or their relatives. In adults, the most common presenting symptom of EE is dysphagia, with or without food bolus impaction. Endoscopic findings of EE include mucosal furrows, corrugated or concentric rings or ridges in the esophagus ("feline esophagus"), with or without tiny whitish exudates. The diagnosis is confirmed by the observation of high counts of eosinophils in the esophageal epithelium (at least 24 /HPF). The cornerstones of medical therapy are either topical or systemic corticosteroids. Additional therapies included leukotriene receptor antagonists (montelukast) and IL-5 blockers (Mepolizumab). Complications of EE such as esophageal strictures should be carefully dilated using either bougies or a balloon. Currently it is still not known whether the late complications of EE can be prevented by the use of anti-inflammatory agents and this can only be demonstrated through further long-term follow-up studies.

An otherwise healthy 20-year-old man was admitted to our hospital with obstruction of the oesophagus by a bolus after eating a chicken meal. These symptoms continued over the past 12 years and required multiple interventions at different hospitals. There was no history of any other previous illness and both the physical examination and routine laboratory tests were unremarkable.. Esophagogastroduodenoscopy (EGD) revealed segmental circular trachea-like constrictions of the esophagus and two stenoses at 35 cm and 40 cm. Histopathology of several biopsies favored the diagnosis of eosinophilic esophagitis.. After initial balloon dilatation and dilatation with a Savary bougie the patient was put on systemic steroids and montelukast (a leukotriene receptor antagonist). The symptoms subsequently disappeared.. Eosinophilic esophagitis, a unique form of esophageal inflammatory disease, consists of dense eosinophilic infiltration of the epithelium and is associated with various macroscopic findings, such as the rare but striking circular trachea-like constrictions, nodules, plaques and other forms of constriction of the esophagus. Several lines of evidence favor an allergic cause. The leading symptom is recurrent dysphagia after solid foods, sometimes accompanied by heart-burn. Medical treatment consists of topical or systemic administration of steroids and/or montelukast. A history of chronic dysphagia after eating solid food, combined with endoscopic findings atypical for reflux disease is highly suspicious of eosinophilic esophagitis in the differential diagnosis of gastroesophageal reflux disease in adults.

Salmeterol (S) and montelukast (M) individually inhibit the obstructive consequences of thermal stimuli such as exercise and hyperventilation (HV), but there is no information on whether these drugs can interact positively.. Randomized trial.. University teaching hospital.. Atopic asthmatic patients with sensitivity to thermal provocations.. Eleven asthmatic patients generated stimulus-response curves to isocapnic HV while breathing frigid air without any interventions and then after pretreatment with 42 mug of S, 10 mg of M, and the combination. The order of testing was randomly determined.. Minute ventilation (Ve) was increased in 20-L increments until FEV(1) fell >or= 15%. Measurements were obtained before and 1 h after drug administration, and then again 5 min after each bout of HV. In the nonintervention trial, the provocation commenced after the patients presented to the laboratory. In the control challenge, the mean (+/- SEM) FEV(1) decreased 24.6 +/- 1.7% from baseline. S and M both increased the mean prechallenge FEV(1) significantly (S, 10.4 +/- 1.7% [p < 0.01]; M, 4.1 +/- 1.3% [p = 0.02]; S + M, p = 0.01). The combination of S + M produced greater bronchodilatation (mean improvement, 12.4 +/- 2.3%) than M alone (p = 0.004), but not greater than S alone (p = 0.80). Both drugs blunted the obstructive response similarly (protection: M, 34.6 +/- 15.1%; S, 60 +/- 8.7%; p = 0.13). The benefits added arithmetically with the combined regimen (protection with S + M, 84.9 +/- 5.5%; p = 0.01 vs S alone; p = 0.003 vs M alone).. These data indicate that the concurrent administration of single standard doses of S and M appears to provide greater protection against thermal stimuli than does either drug alone. Further experimentation will be required to ascertain whether the combination will provide additional clinical benefits to patients over those of the single agents.

Eosinophilic oesophagitis is a rarely diagnosed condition involving eosinophil infiltration of the oesophageal mucosa and creating significant symptoms of dysphagia. Failure to diagnose this disorder relates to reluctance to biopsy an apparently normal oesophagus. This is essential for histological diagnosis. To date, treatment success has been achieved only with corticosteroids. We describe here the use of an eosinophil stabilising agent Montelukast for the symptomatic relief of these patients.. Twelve patients have been identified with this condition in our unit since 1995, after thorough investigation of their dysphagia. We commenced eight of these patients on the leukotriene receptor antagonist Montelukast to symptomatically improve their swallowing while avoiding the use of long term corticosteroids.. Many of these patients had been previously misdiagnosed, and therefore inappropriately and unsuccessfully treated for an extensive period prior to referral to our unit. All patients were unresponsive to acid suppression therapy alone but showed improvement in their swallowing on Montelukast. Six of eight reported complete subjective improvement, five patients remaining completely asymptomatic on a maintenance regimen.. Eosinophilic oesophagitis is a disease that is often misdiagnosed due to lack of awareness and reluctance of clinicians to biopsy an apparently normal oesophagus in dysphagic patients, and therefore obtain a histological diagnosis. Investigation of these patients adds further evidence to this condition being a separate pathological state from gastro-oesophageal reflux and eosinophilic enteritis. Montelukast has been found to be of significant help in the symptomatic control of these patients while avoiding long term corticosteroids use.
