Allergy today is a public health concern of pandemic proportions, affecting more than 150 million people in Europe alone. In view of epidemiological trends, the European Academy of Allergy and Clinical Immunology (EAACI) predicts that within the next few decades, more than half of the European population may at some point in their lives experience some type of allergy.Not only do allergic patients suffer from a debilitating disease, with the potential for major impact on their quality of life, career progression, personal development and lifestyle choices, but they also constitute a significant burden on health economics and macroeconomics due to the days of lost productivity and underperformance. Given that allergy triggers, including urbanization, industrialization, pollution and climate change, are not expected to change in the foreseeable future, it is imperative that steps are taken to develop, strengthen and optimize preventive and treatment strategies.Allergen specific immunotherapy is the only currently available medical intervention that has the potential to affect the natural course of the disease. Years of basic science research, clinical trials, and systematic reviews and meta-analyses have convincingly shown that allergen specific immunotherapy can achieve substantial results for patients, improving the allergic individuals’ quality of life, reducing the long-term costs and burden of allergies, and changing the course of the disease. Allergen specific immunotherapy not only effectively alleviates allergy symptoms, but it has a long-term effect after conclusion of the treatment and can prevent the progression of allergic diseases.Unfortunately, allergen specific immunotherapy has not yet received adequate attention from European institutions, including research funding bodies, even though this could be a most rewarding field in terms of return on investments, translational value and European integration and, a field in which Europe is recognized as a worldwide leader. Evaluation and surveillance of the full cost of allergic diseases is still lacking and further progress is being stifled by the variety of health systems across Europe. This means that the general population remains unaware of the potential use of allergen specific immunotherapy and its potential benefits.We call upon Europe’s policy-makers to coordinate actions and improve individual and public health in allergy by:Promoting awareness of the effectiveness of allergen specific immunotherapyUpdating national healthcare policies to support allergen specific immunotherapyPrioritising funding for allergen specific immunotherapy researchMonitoring the macroeconomic and health economic parameters of allergyReinforcing allergy teaching in medical disciplines and specialtiesThe effective implementation of the above policies has the potential for a major positive impact on European health and well-being in the next decade.

Several clinical studies have confirmed the effectiveness of montelukast 10mg orally in adults with both asthma and allergic rhinitis. The objective of this phase IV study was to investigate the efficacy and safety of montelukast 10mg in adults with both asthma and allergic rhinitis in a real-life setting. Data from 5855 patients (mean age: 42.8+/-15.4 years) were collected and analyzed following treatment for 4-6 weeks. Efficacy was analyzed by comparing baseline values of: general, day- and night-time improvement in asthma symptoms, need for rescue medication or inhaled corticosteroids (ICSs), general and specific improvement in allergic rhinitis symptoms, reduction in rhinitis medication use, and general and specific quality of life (QoL) improvement with values collected at the end of the observation period of 4-6 weeks. Following treatment with 10mg montelukast 86.5% (n=4547) of patients reported a strong or marked improvement in day-time asthma symptoms and 88.5% (n=4367) reported improvement in night-time symptoms. A similarly high proportion of patients had a strong or marked improvement in all symptoms of allergic rhinitis (i.e. sneezing/itching (84%), rhinorrhea (81.7%), nasal congestion (79.3%), watery eyes (78.4%) and red or burning eyes (77.7%). The use of asthma and rhinitis medication was also reduced. 92.3% (n=5685) of all patients intended to continue montelukast therapy. Overall QoL was "very good" or "good" in 85.2% of patients (n=4991) and a "strong" or "marked" improvement in each of the four domains of sleep, work, everyday life and physical activity. Montelukast was well tolerated. Adverse drug reactions occurred in 14 out of 6158 patients. None of the adverse events was serious. Accordingly, montelukast 10mg is a safe and effective treatment for patients with both asthma and allergic rhinitis.

From these data we conclude that the specific cysteinyl LT1-receptor antagonist montelukast can inhibit PAF-induced eosinophil transmigration through cultured HUVEC monolayers.

Current therapy for asthma with inhaled corticosteroids and long-acting inhaled β(2)-agonists is highly effective, safe, and relatively inexpensive, but many patients remain poorly controlled. Most advances have been through improving these drug classes and a major developmental hurdle is to improve existing drug classes. Major unmet needs include better treatment of severe asthma (which has some similarity to chronic obstructive pulmonary disease), as well as curative therapies for mild to moderate asthma that do not result in the return of symptoms when the treatment is stopped. Several new treatments are in development, but many are specific, targeting a single mediator or receptor, and are unlikely to have a major clinical impact, although they may be effective in specific asthma phenotypes (endotypes). Drugs with more widespread effects, such as kinase inhibitors, may be more effective but have a greater risk of side effects so inhaled delivery may be needed. Several new treatments target the underlying allergic/immune process and would treat concomitant allergic diseases. Improved immunotherapy approaches have the potential for disease modification, although prospects for a cure are currently remote.
