OBJECTIVES: To identify and synthesise evidence on the diagnostic accuracy of FE NO for asthma in adults. MATERIALS AND METHODS: Systematic searches (nine key biomedical databases and trial registers) were carried out to November 2014. Records were included if they: recruited patients with the symptoms of asthma; used a single set of inclusion criteria; measured FE NO50 in accordance with American Thoracic Society guidelines, 2005 (off-line excluded); reported/allowed calculation of true positive, true negative, false positive and false negative patients as classified against any reference standard...

Angioedema is a localized swelling of the subcutaneous and submucosal tissues that is frequently associated with urticaria but that can also occur alone. It can become life-threatening when the larynx is involved or painful when the gastrointestinal tract is affected. Angioedema without weals can be hereditary or acquired.

BACKGROUND: The mechanisms involved in the amplification of the mast cell response during anaphylaxis are unclear. Mouse models of anaphylaxis demonstrate the critical involvement of neutrophils. These innate immune cells are highly abundant in peripheral blood and can be rapidly activated to trigger both local and systemic inflammation. OBJECTIVE: To investigate neutrophil activation in peripheral blood during acute human anaphylaxis. METHODS: Patients presenting to the Emergency Department with anaphylaxis underwent blood sampling upon enrolment and at up to three subsequent time points...

BACKGROUND: Rho kinases (ROCKs) contribute to allergic airways disease. ROCKs also play a role in lymphocyte proliferation and migration. OBJECTIVE: To determine the role of ROCK2 acting within CD4(+) cells in allergic airways responses. METHODS: ROCK2 haploinsufficient (ROCK2(+/-) ) and wildtype mice were sensitized with ovalbumin (OVA). ROCK2(+/-) mice then received either CD4(+) cells from ROCK2 sufficient OVA TCR transgenic (OT-II) mice or saline i...

BACKGROUND: Autophagy and neutrophil extracellular DNA traps (NETs) are implicated in asthma; however, their roles in asthma pathogenesis have not been elucidated. OBJECTIVES: We compared autophagy and NET production levels from peripheral blood neutrophils (PBNs) of patients with severe asthma (SA) and non-severe asthma (NSA). Additionally, we investigated the inflammatory effects of NETs on human airway epithelial cells (AECs) and peripheral blood eosinophils (PBEs)...

Making an accurate diagnosis of occupational asthma (OA) is, generally, important. The condition has not only significant health consequences for affected workers, but also substantial socio-economic impacts for workers, their employers and wider society. Missing a diagnosis of OA may lead to continued exposure to a causative agent and progressive worsening of disease; conversely, diagnosing OA when it is not present may lead to inappropriate removal from exposure and unnecessary financial and social consequences...

BACKGROUND: Treatment with omalizumab has shown a positive effect on food allergies, but no dosages are established. Basophil allergen threshold sensitivity (CD-sens) can be used to objectively measure omalizumab treatment efficacy and correlates with the outcome of Double Blind Placebo Controlled Food Challenge to peanut. OBJECTIVE: To evaluate if individualized omalizumab treatment monitored by CD-sens could be an effective intervention for suppression of allergic reactions to peanut...

BACKGROUND: Oral tolerance induction in early life is a promising approach for food allergy prevention. Its success requires the identification of factors necessary for its persistence. OBJECTIVES: We aimed to assess in mice duration of allergy prevention by breastfeeding-induced oral tolerance and whether oral TGF-β supplementation after weaning would prolong it. METHODS: We quantified ovalbumin (OVA) and OVA specific immunoglobulins levels by ELISA in milk from the EDEN birth cohort...

BACKGROUND: Genetic variants for IgE-mediated peanut allergy are yet to be fully characterized and to date only one genome-wide association study (GWAS) has been published. OBJECTIVE: To identify genetic variants associated with challenge proven peanut allergy. METHODS: We carried out a GWAS comparing 73 infants with challenge-proven IgE-mediated peanut allergy against 148 non-allergic infants (all ~ 1 year old). We tested a total of 3.8 million single nucleotide polymorphism (SNPs), as well as imputed HLA alleles and amino acids...

BACKGROUND: Inconsistent results have been reported regarding IL-5 blockade treatment in asthma. There were no direct between-treatment comparisons. Only differences between each drug and placebo were studied. METHODS: We identified all RCTs with anti-IL5 treatments for asthma patients over the 1990-September 2015 period. RCT were searched on Medline, Cochrane and Embase. At least 50 patients were enrolled in each study. Outcomes considered were: exacerbation rate reduction, FEV1 changes, ACQ-5 improvement, adverse events and serious adverse events...

BACKGROUND: In contrast to eosinophils and neutrophils, the regulation of the lifespan of human basophils is poorly defined, with the exception of the potent anti-apoptotic effect of IL-3 that also promotes pro-inflammatory effector functions and phenotypic changes. Type I IFNs (IFN-α, IFN-β), which are well known for their anti-viral activities, have the capacity to inhibit allergic inflammation. OBJECTIVE: To elucidate whether type I IFNs have the potential to abrogate the lifespan and/or effector functions of human basophils...

BACKGROUND: Skin colonization or infection with Staphylococcus aureus is known to trigger aggravation of atopic dermatitis (AD). However, the exact mechanisms by which S. aureus can worsen AD are unknown. OBJECTIVE: We investigated whether and how S. aureus-derived membrane vesicles (MVs) contribute to worsening of AD. METHODS: Immunohistochemical and immunoelectron microscopic analyses were performed to detect staphylococcal protein A (SPA) in the epidermis of AD lesions...

BACKGROUND: Immunological biomarkers are the key to the diagnosis of allergic bronchopulmonary aspergillosis (ABPA) and fungal sensitisation, but how these relate to clinically relevant outcomes is unclear. OBJECTIVES: To assess how fungal immunological biomarkers are related to fixed airflow obstruction and radiological abnormalities in moderate to severe asthma. METHODS: Cross-sectional study of 431 asthmatics. Inflammatory biomarkers, lung function and an IgE fungal panel to colonising filamentous fungi, yeasts and fungal aeroallergens were measured...

BACKGROUND: Pharmacogenetics studies of anti-inflammatory medication of asthma have expanded rapidly in recent decades, but the clinical value of their findings remain limited. OBJECTIVE: To perform a systematic review of pharmacogenomics and pharmacogenetics of inhaled corticosteroids (ICS) and leukotriene modifiers (LTMs) in asthmatic patients. METHODS: Articles published between 1999 and June 2015 were searched using PubMed and Embase. Pharmacogenomics/genetics studies of asthmatic patients using ICS or LTMs were included if ≥1 of the following outcomes were studied: lung function, exacerbation rates or asthma symptoms...

J-M Grouin, E Vicaut, P Devillier
BACKGROUND: Over the past decade, regulatory bodies and scientific societies recommended, as primary efficacy outcome, a score that reflects both symptom severity and use of rescue medication for clinical trials in allergy immunotherapy (AIT). OBJECTIVE: We sought to compare the results obtained with two subject-specific scores, the Combined Score (CS) and the Adjusted Symptom Score (AdSS), for assessment of AIT in seasonal allergic rhinoconjunctivitis due to birch and grass pollen allergens...

We have been aware of, and acknowledged in the paper, some limitations of the study. The detailed statistical analysis of asthma cases can be complex as mentioned by Erbas et al, with diagnosis in the very young children being difficult and hospital re-admission often occurring. However, we were unable to identify re-admissions with daily aggregated data. For this reason, we could not rule out the possibility of misclassification of control days in the case-crossover (CCO) analysis, which would occur if a case was re-admitted for asthma within the 28 control day stratum...

BACKGROUND: Allergen-specific immunotherapy (AIT) with birch pollen generates Bet v 1-specific immunoglobulin (Ig)G4 which blocks IgE-mediated hypersensitivity mechanisms. Whether IgG4 specific for Bet v1a competes with IgE for identical epitopes or whether novel epitope specificities of IgG4 antibodies are developed is under debate. OBJECTIVE: We sought to analyze the epitope specificities of IgE and IgG4 antibodies from sera of patients who received AIT. METHODS: 15 sera of patients (13/15 received AIT) with Bet v 1a-specific IgE and IgG4 were analyzed...

BACKGROUND: Affecting 19% of women, postpartum depression is a major concern to the immediate health of mothers and infants. In the longterm, it has been linked to the development of early-onset asthma at school entry, but only if the depression persists beyond the postnatal period. No studies have tested whether associations with postpartum depressive symptoms and early-onset asthma phenotypes persist into later school age. OBJECTIVE: To determine associations between maternal postpartum depressive symptoms and childhood asthma between the ages of 5-10 by using a nested longitudinal design...

BACKGROUND: An important percentage of subjects diagnosed with chronic upper airway disease report alcohol-induced worsening of their symptoms. The prevalence and characteristics of respiratory reactions provoked by alcohol-containing drinks has not been fully investigated yet. OBJECTIVE: The aim of this study was to estimate the prevalence and characteristics of alcohol hyper-responsiveness in patients with chronic airway disease and healthy controls. Furthermore, nasal inflammation was evaluated in nasal polyp patients with and without hyper-responsiveness...
