Background: A significant correlation has been previously demonstrated between the quantum of radiofrequency treatment delivered at bronchial thermoplasty and the degree of improvement in an asthmatic patient's symptoms. The standard bronchoscope used for bronchial thermoplasty has an outer diameter of 4.8 mm at the distal tip. Thinner bronchoscopes are now available with the same internal channel size (2.0 mm). This study assesses whether using a thinner bronchoscope facilitates bronchial thermoplasty by increasing the radiofrequency activations delivered...

Seafood allergy is a hypersensitive disorder with increasing prevalence worldwide. Effective and accurate diagnostic workup for seafood allergy is essential for clinicians and patients. Parvalbumin and tropomyosin are the most common fish and shellfish allergens, respectively. The diagnosis of seafood allergies is complicated by cross-reactivity among fish allergens and between shellfish allergens and other arthropods. Current clinical diagnosis of seafood allergy is a complex algorithm that includes clinical assessment, skin prick test, specific IgE measurement, and oral food challenges...

Introduction: Respiratory infections have significant effects on childhood asthma. Viral respiratory infections, such as rhinovirus and respiratory syncytial virus are likely to be important in the development and exacerbation of asthma. In this study, we investigated the nasopharyngeal colonization in children with asthma to determine the prevalence of pathogens and their contribution to respiratory symptoms and airway resistance during winter. Methods: From December 2016 to March 2017, 50 nasopharyngeal specimens were collected from 18 patients (age, 5...

Background: There are few clinical trials that assess the efficacy of antihistamines in very young children. Rupatadine is a second-generation antihistamine indicated for the treatment of allergic rhinitis (AR) and urticaria. In this study, AR symptoms were evaluated before and after daily 1 mg/mL rupatadine oral solution administration in 2-5-year-old children. Methods: A multicenter open-label study was carried out in 2-5-year-old children with AR. Safety assessments were collected during the study including spontaneous adverse events, vital signs, and electrocardiogram (QTc interval)...

Background and objective: Benralizumab (Fasenra™ ) has recently been approved as add-on maintenance treatment for adult patients with severe eosinophilic asthma inadequately controlled despite high-dosage inhaled corticosteroids plus long-acting β2 -agonists. We aimed to identify and describe the clinical characteristics and disease burden of patients with severe, uncontrolled, eosinophilic asthma in France who may be eligible for treatment with benralizumab. Patients and methods: This was a retrospective analysis of a prospective, noninterventional, observational study of patients in France enrolled in the Asthma and Bronchial Obstruction Cohort (COBRA)...

Background: Asthma is one of the most common chronic diseases of childhood affecting 6.2 million (8.4%) children (<18 years old) in the USA. Asthma is also a leading cause of school absenteeism. Daily administration of preventive asthma medications improves asthma control. However, poor medication adherence is one of the barriers in achieving improved asthma outcomes. School-based supervised asthma therapy programs have been implemented to address this barrier. Objectives: To conduct a review of the literature on school-based supervised asthma therapy interventions and the effect on outcomes in children with persistent asthma...

Purpose: Prior work suggests a threshold of four courses/year of systemic corticosteroid (SCS) therapy is associated with adverse consequences. The objective of this study was to investigate the onset of adverse outcomes beginning at SCS initiation in a broad asthma population. Patients and methods: This historical matched cohort study utilized anonymized, longitudinal medical record data (1984-2017) of patients (≥18 years) with active asthma. Matched patients with first SCS prescription (SCS arm) and no SCS exposure (non-SCS arm) were followed until first outcome event...

Background: Purinergic receptors control cell proliferation, apoptosis, migration, inflammation, and cytokine secretion. Increased expression of specific purinergic receptors is reported in asthma. The role of purinergic P2Y6 receptors (P2Y6R) in asthma is controversial. Hypothesis: P2Y6R activation in asthma improves pulmonary function and reduces inflammation and smooth muscle amount. Methods: Female mice (C57/BL6, age 30 days) were randomly assigned to receive intranasal house dust mite (HDM) antigen (40 or 80 µg) or saline, 5 days/week, for 6 weeks...

Epinephrine is a life-saving medication used to treat systemic allergic reactions including anaphylaxis. Epinephrine autoinjectors (EAIs) are expensive and worldwide availability is limited. Epinephrine prefilled syringes and epinephrine kits are potentially lower-cost alternatives to EAIs. Advantages, disadvantages, and costs of available products are discussed. The socioeconomic factors impacting access to EAIs are described.

Epinephrine is the only effective treatment for anaphylaxis but studies routinely show underutilization. This is especially troubling given the fact that fatal anaphylaxis has been associated with delayed administration of epinephrine. Many potential barriers exist to the proper use of epinephrine during an anaphylactic reaction. This article will explore both patient-and physician-related factors, as well as misconceptions that all contribute to the underuse of epinephrine for the treatment of anaphylaxis.

Anaphylaxis is the most serious of all allergic reactions and can be fatal. The diagnosis is frequently delayed, and misdiagnosis often occurs with asthma or urticaria. Biomarkers such as tryptase are not routinely checked, and appropriate treatment with epinephrine is not administered in a majority of cases, increasing the risk of poor outcomes. The objective of this review is to provide a better understanding of the pathophysiology of anaphylaxis with a description of phenotypes, endotypes, and biomarkers available in both the clinical and research settings...

Anaphylaxis is a severe and potentially life-threatening allergic reaction. There are numerous potential causes, with food allergy being the leading cause in children and the focus of this review. Most reactions involve an IgE-mediated mechanism, although non-IgE-mediated and nonimmunologic reactions can occur. Various cofactors to be discussed can place certain individuals at an increased risk of severe or fatal anaphylaxis. The clinical manifestations of anaphylaxis are broad and may involve multiple body systems...

Standardization of the methacholine inhalation challenge, the most common direct bronchoprovocation test, is important. One aspect of standardization is the appropriate washout period for pharmacologic agents which affect the response. This review summarizes the available data on pharmacologic inhibition of the methacholine response. Specific (anti-muscarinic) agents demonstrate marked bronchoprotection (up to 7 days for the long-acting drugs) which lasts longer than the duration of bronchodilation. The functional antagonist (beta 2 agonist class of medications) shows marked, but less, bronchoprotection which is relatively short lived and is similar to the duration of bronchodilator efficacy...

Background: Sputum eosinophil and fractional exhaled nitric oxide (FeNO), noninvasive biomarkers of local eosinophilic airway inflammation, can be used to assess asthma outcome. Nevertheless, the clinical application of the association between FeNO and sputum eosinophil is controversial. The aim of the study was to investigate the predictive relationship between FeNO and sputum eosinophil in uncontrolled asthmatic patients and the correlation between sputum eosinophil and FeNO in bronchial reversibility and bronchial hyperresponsiveness (BHR)...
