Cysteinyl leukotrienes (CysLTs) play a key role in inflammatory diseases such as asthma and their receptors' antagonists are currently used as anti-asthmatic drugs. CysLTs have also been found to participate in other inflammatory reactions. Here, we reported that in rheumatoid arthritis (RA) animals model, collagen-induced arthritis, (CIA), CysLT1, a receptor for CysLTs, was up-regulated in hind paw and lymph node, while CysLTs levels in the blood were also higher than normal mice. Montelukast, a drug targeting CysLT1, has been shown to effectively reduce the CIA incidence, peak severity, and cumulative disease scores...

Preschool wheeze occurs in half of the children before they reach 6 y of age and recurrence is also common. Recurrent preschool wheeze is classified as either typical or atypical. For typical recurrent preschool wheeze, the diagnoses are either asthma or bronchiolitis/bronchitis. Responsiveness to a properly administered bronchodilator confirms asthma, atopic or otherwise. All atypical preschool wheeze should be referred to pediatric respirologist for assessment. Lung function test by impulse oscillometry (IOS) before and after bronchodilator is helpful to confirm airway hyperresponsiveness, an essential feature of asthma...

The role of leukotrienes and prostaglandins in development of atopy has been prototypically established in studies of asthma pathogenesis. Likewise, both in vitro and in vivo studies of atopic dermatitis have demonstrated that these molecules maintain important pathophysiologic roles. Thus, it follows that targeted therapies against these molecules may be promising in management of atopic dermatitis. Montelukast has had questionable efficacy in patients with atopic dermatitis, while small pilots using zileuton did have some clinically significant improvement...

Severe asthma affects between 5% and 10% of patients with asthma worldwide and requires best standard therapies at maximal doses, but there is a subgroup of patients refractory to all treatments. We share a case report of a 53-year-old woman with a history of severe allergic asthma that progressively worsened over the years despite the best therapy. She had been hospitalized 35 times, including nine admissions to the respiratory intensive care unit due to severe exacerbations. To rule out other possible diagnoses, several investigations were performed, such as computed tomography scan of the chest and neck, fiberoptic laryngoscopy, antineutrophil cytoplasmic antibodies, and complete blood cell count...

Long-term exposure to overloaded mechanical environment induces bone fatigue damage symptoms and osteoblast damages. Montelukast is a selective cysteinyl leukot-riene receptor 1 (cysLT1R) antagonist, which has been used for the treatment of bronchial asthma in clinics. In the current study, we have identified a novel pharmacological role of montelukast by finding that it has protective properties against overload damage in osteoblastic MC3T3-E1 cells. Firstly, our results show that CysLT1R is expressed in MC3T3-E1 cells...

Montelukast, a selective leukotriene receptor antagonist, is recommended in guidelines for the treatment of asthma in both children and adults. However, its effectiveness is debated, and recent studies have reported several adverse events such as neuropsychiatric disorders and allergic granulomatous angiitis. This study aims to obtain more insight into the safety profile of montelukast and to provide prescribing physicians with an overview of relevant adverse drug reactions in both children and adults. We retrospectively studied all adverse drug reactions on montelukast in children and adults reported to the Netherlands Pharmacovigilance Center Lareb and the WHO Global database, VigiBase(®) until 2016...
