BACKGROUND: Airway responsiveness and inflammation are associated with the clinical manifestations of asthma and the response to pharmacological therapy. OBJECTIVE: To investigate if airway responsiveness and inflammatory characteristics are related to asthma exacerbations during pregnancy. MATERIALS AND METHODS: In women with asthma who were prescribed controller medication and monitored closely during pregnancy, the risk of exacerbations was analyzed in relation to postpartum measures of fractional exhaled nitric oxide (FENO), skin prick test reactivity, static and dynamic lung volumes, diffusing capacity for carbon monoxide, bronchial responsiveness to inhaled mannitol, and inflammatory characteristics in induced sputum...

The increasing understanding of the molecular biology and the etiopathogenetic mechanisms of asthma helps in identification of numerous phenotypes and endotypes, particularly for severe refractory asthma. For a decade, the only available biologic therapy that met the unmet needs of a specific group of patients with severe uncontrolled allergic asthma has been omalizumab. Recently, new biologic therapies with different mechanisms of action and targets have been approved for marketing, such as mepolizumab. Other promising drugs will be available in the coming years, such as reslizumab, benralizumab, dupilumab and lebrikizumab...

REVIEW
Emma R McIvor, R Andrew McIvor
Tiotropium is a long-acting muscarinic antagonist (LAMA) that exerts its bronchodilatory effect by blocking endogenous acetylcholine receptors in the airways. Its safety and efficacy are well established for the treatment of COPD, and it is now being recognized for its role in improving lung function and control in asthma. This review discusses the evolving role of tiotropium delivered by the Respimat(®) in patients across the range of asthma severities and ages, and provides an overview of safety and efficacy data...

Increasing dependence on advanced technologies in the 21st century has created a dilemma between the practice and business of medicine. From information technology to robotic surgery, new technologies have expanded treatment possibilities and have potentially improved patient outcomes and safety. Simultaneously, their escalating costs limit access for certain patients and health care facilities. Nevertheless, medical decisions should not simply be based on cost. Input from physicians and other health care specialists as well as adherence to best practice position statements, are vital to implementing truly cost-effective strategies in medicine...

Heterogeneity of asthma and difficulty in achieving optimal control are the major challenges in the management of asthma. To help attain the best possible clinical outcomes in patients with asthma, several guidelines provide recommendations for patients who will require a referral to a specialist. Such referrals can help in clearing the uncertainty from the initial diagnosis, provide tailored treatment options to patients with persistent symptoms and offer the patients access to health care providers with expertise in the management of the asthma; thus, specialist referrals have a substantial impact on disease prognosis and the patient's health status...

Food protein-induced enterocolitis syndrome (FPIES) is a potentially severe presentation of non-IgE-mediated gastrointestinal food allergy (non-IgE-GI-FA) with heterogeneous clinical manifestations. Acute FPIES is typically characterized by profuse vomiting and lethargy, occurring classically 1-4 hours after ingestion of the offending food. When continuously exposed to the incriminated food, a chronic form has been described with persistent vomiting, diarrhea, and/or failure to thrive. Although affecting mainly infants, FPIES has also been described in adults...

Recent studies have shown that approximately 70% of patients with severe atopic dermatitis (AD) develop asthma. Development of AD in infancy and subsequent other atopic diseases such as asthma in childhood is referred to as atopic march. However, a causal link between the diseases of atopic march has remained largely unaddressed, possibly due to lack of a proper animal model. Recently, we developed an AD rat model showing chronically relapsing dermatitis and scratching behaviors induced by neonatal capsaicin treatment...

BACKGROUND: Accurate tracking of the administered dose of asthma rescue inhalers is critical for optimal disease management and is related to reductions in rates of unscheduled health care utilization in asthma patients. There are few published data on the real-world impact of rescue inhalers with integrated dose counters (IDCs) on health care resource utilization (HRU) for asthma patients. This study evaluates HRU among users of ProAir(®) hydrofluoroalkane (HFA) (albuterol sulfate inhalation aerosol), with IDC versus without IDC, in asthma patients...

This paper, developed by consensus of staff physicians of accredited asthma units for the management of severe asthma, presents information on the process and requirements for already-existing asthma units to achieve official accreditation by the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Three levels of specialized asthma care have been established based on available resources, which include specialized units for highly complex asthma, specialized asthma units, and basic asthma units. Regardless of the level of accreditation obtained, the distinction of "excellence" could be granted when more requirements in the areas of provision of care, technical and human resources, training in asthma, and teaching and research activities were met at each level...

Sesame is an important global allergen affecting ~0.1% of the North American population. It is a major cause of anaphylaxis in the Middle East and is the third most common food allergen in Israel. We conducted a systematic review of original articles published in the last 10 years regarding the diagnosis and management of sesame allergy. Skin prick testing appears to be a useful predictor of sesame allergy in infants, although data are less consistent in older children and adults. The diagnostic capacity of serum-specific immunoglobulin E is poor, especially in studies that used oral food challenges to confirm the diagnosis...

BACKGROUND: Severe asthma is a largely heterogeneous disease with varying phenotypic profiles. The relationship between specific allergen sensitization and asthma severity, particularly in Asia, remains unclear. We aim to study the prevalence of specific allergen sensitization patterns and investigate their association with outcomes in a severe asthma cohort in an Asian setting. METHODS: We conducted a cross-sectional study of patients receiving step 4 or 5 Global Initiative for Asthma treatment...

Children with asthma that is refractory to high levels of prescribed treatment are described as having problematic severe asthma. Those in whom persistent symptoms result from a failure of basic asthma management are described as having "difficult asthma", while those who remain symptomatic despite these factors having been addressed are described as having "severe therapy-resistant asthma" (STRA). The majority of children have difficult asthma; asthma that is poorly controlled because of a failure to get the basics of asthma management right...

Pavani Rangachari
Asthma is associated with substantial health care expenditures, including an estimated US$56 billion per year in direct costs. A recurring theme in the asthma management literature is that costly asthma symptoms, including hospitalizations and multiple emergency department (ED)/outpatient visits, can often be prevented through patient/family adherence to the national (National Institutes of Health Expert Panel Report-3) guidelines for effective self-management of asthma, specifically 1) medication adherence and 2) environmental trigger avoidance, as outlined in the patient's personalized Asthma-Action Plan...

The use of egg protein preparations in clinical trials to reduce the incidence of egg allergy among infants includes a number of preparations of egg. These include whole egg, egg white protein, and egg yolk preparations. The study of the differential immune responses to these allergenic proteins in comparison is suggested as a future research area of investigation.

PURPOSE: Airway inflammation can be detected by lung sound analysis (LSA) at a single point in the posterior lower lung field. We performed LSA at 7 points to examine whether the technique could identify the location of airway inflammation in patients with asthma. PATIENTS AND METHODS: Breath sounds were recorded at 7 points on the body surface of 22 asthmatic subjects. Inspiration sound pressure level (ISPL), expiration sound pressure level (ESPL), and the expiration-to-inspiration sound pressure ratio (E/I) were calculated in 6 frequency bands...

BACKGROUND: The measure of fractional exhaled nitric oxide (FENO) in the airways is a useful tool to guide the diagnosis and titration of inhaled corticosteroids in patients with asthma. However, its role in diagnosis of allergic rhinitis (AR), especially in subjects with asthma, is not well established. OBJECTIVE: To study the cutoff of nasal FENO in the diagnosis of subjects with AR and AR-asthma compared to age-matched subjects without AR or asthma and its correlations with the clinical and functional characteristics...
