RATIONALE: Eosinphilic gastroenteritis (EG) is a gastrointestinal disorder characterized by eosinophilic infiltration with various manifestations. The diagnosis is usually confirmed by an endoscopic biopsy, which is considered a safe and routine procedure for the majority. PATIENT CONCERNS: We report a 54-year-old male who was presented with intermittent periumbilical pain and melena, and only revealed verrucous gastritis by endoscopy. DIAGNOSES: The patient's condition worsened two days after the endoscopic biopsy, and another endoscopy found hematoma and ulcers in upper gastrointestinal tract...

Renal toxicity is one of the most severe complications that can occur with cisplatin (CIS) administration in cancer patients. Montelukast (ML) renoprotective outcome contrary to CIS-drawn nephrotoxicity remains obscure. Therefore, adult male Sprague-Dawley rats were orally given ML (10 and 20 mg/kg/day) 5 days before and after single CIS (5 mg/kg; i.p.) treatment. ML returned blood urea nitrogen, as well as serum creatinine and gamma glutamyl transferase that were elevated by CIS to normal level. The improved kidney function tests corroborated the attenuation of CIS renal injury at the microscopical level...

BACKGROUND: It has recently been shown that the leukotriene receptor antagonist montelukast rejuvenates aged brains in rats. The question is whether this commonly used, systemic, anti-asthmatic medicine has a similar effect in humans? RESULTS: We approached this issue by doing statistical analyses based on the Norwegian Prescription Database. The Database lists all prescription-based medications in Norway, but not drugs given to people who are in hospitals or nursing homes...

Although montelukast is generally well tolerated, postmarketing studies have reported serious neuropsychiatric adverse drug reactions (ADRs) leading to a United States Food and Drug Administration black box warning. The objective of this study was to determine the incidence of neuropsychiatric ADRs leading to discontinuation of montelukast in asthmatic children.We conducted a retrospective cohort study in children aged 1-17 years initiated on montelukast. In a nested cohort study, children initiated on montelukast as monotherapy or adjunct therapy to inhaled corticosteroids (ICS) were matched to those initiated on ICS monotherapy...

BACKGROUND AND PURPOSE: Predicting the risk of drug-induced adverse psychiatric effects is important but currently not possible in non-human species. We investigated whether the affective bias test (ABT) could provide a preclinical method with translational and predictive validity. EXPERIMENTAL APPROACH: The ABT is a bowl-digging task, which quantifies biases associated with learning and memory. Rats encounter independent learning experiences, on separate days, under either acute manipulations (e...

OBJECTIVE: Asthma is a chronic inflammatory airway disease induced by many environmental factors. The inhalation of allergens and pollutants promote the reactive oxygen species (ROS) production leading to airway inflammation, hyper-responsiveness and remodeling in allergic asthma. The effects of asthma medications on ROS production are unclear. The present study investigated the anti-ROS effects of current asthma medications including inhaled corticosteroid (ICS; budesonide and fluticasone), leukotriene receptor antagonist (LTRA; montelukast), long acting β2 agonists (LABAs; salmeterol and formoterol) and a new extra-LABA (indacaterol)...

Developing novel chemo-prevention techniques and advancing treatment are key elements to beating lung cancer, the most common cause of cancer mortality worldwide. Our previous cohort study showed that cysteinyl leukotriene receptor antagonists, mainly montelukast, decreased the lung cancer risk in asthma patients. In the current study, we conducted in vivo and in vitro experiments to demonstrate the inhibiting effect of montelukast on lung cancer and to investigate the underlying mechanisms. Using Lewis lung carcinoma-bearing mice, we showed that feeding montelukast significantly delayed the tumor growth in mice (p < 0...
