Background
Breastfeeding may have immune modulatory effects that influence the development of childhood allergic sensitization and atopic diseases. We aimed to examine the associations of breastfeeding with childhood allergic sensitization, inhalant or food allergy and eczema, and whether any association was affected by disease‐related modification of the exposure or modified by maternal history...
Background
Omalizumab, an anti‐IgE antibody, is used to treat patients with severe allergic asthma. The evolution of lung function parameters over time and the difference between omalizumab responder and nonresponder patients remain inconclusive. The objective of this real‐life study was to compare the changes in forced expiratory volume in 1 second (FEV1) of omalizumab responders and nonresponders...
Background
Chronic spontaneous urticaria (CSU) can be debilitating, difficult to treat, and frustrating for patients and physicians. Real‐world evidence for the burden of CSU is limited. The objective of this study was to document disease duration, treatment history, and disease activity, as well as impact on health‐related quality of life (HRQoL) and work among patients with inadequately controlled...
Immediate drug hypersensitivity reactions (IDHR) to moxifloxacin constitute a pathomechanistic conundrum and a diagnostic challenge. Our objective was to study whether simultaneous phenotyping and quantification of histamine release might add to our knowledge about the basophil activation properties of moxifloxacin and constitute a reliable diagnostic aid. Fifteen patients with an IDHR to moxifloxacin...
Since its discovery, the understanding of stem/progenitor cells raised dramatically in the last decade. Their regenerative potential is important to develop new therapeutic applications, but the identification advanced much faster than our understanding of stem/progenitor cells. In nasal polyposis, little is known about stem cells/progenitor cells and their ability. However, the further characterization...
Background
The ideal nomenclature of atopic dermatitis (AD) / atopic eczema (AE) has long been contested. However, it is becoming increasingly clear that the disparate nomenclature of this disease may have important deleterious ramifications for clinical care and research.
Materials and Methods
An electronic questionnaire regarding the preferred nomenclature for AD was sent to councilors of the...
Background
Epithelial barrier dysfunction is a central feature in the pathogenesis of allergic disease. Epithelial‐to‐mesenchymal transition (EMT) has been proposed as one mechanism afflicting barrier in asthma. However, genes and pathways involved in aberrant epithelial‐mesenchymal signaling, and their relationship to asthma severity, are poorly understood.
Methods
We used unbiased gene network...
Background
Quality of life (QOL) is impaired in patients with food allergy and improves following oral immunotherapy (OIT). However, the treatment itself is prolonged and demanding. We examined changes in patient QOL during OIT for food allergy.
Methods
The FAQLQ‐PF was administered to children aged 4‐12 years undergoing OIT for milk, peanut, or egg allergy, at the beginning and after 4 months...
Background
Asthma is a heterogeneous chronic disease with different phenotypes and treatment responses. Thus, there is a high clinical need for molecular disease biomarkers to aid in differentiating these distinct phenotypes. As MicroRNAs (miRNAs), that regulate gene expression at the post‐transcriptional level, are altered in experimental and human asthma, circulating miRNAs are attractive candidates...
Background
Asthma is an allergic airway disease (AAD) caused by aberrant immune responses to allergens. Protein phosphatase‐2A (PP2A) is an abundant serine/threonine phosphatase with anti‐inflammatory activity. The ubiquitin proteasome system (UPS) controls many cellular processes, including the initiation of inflammatory responses by protein degradation. We assessed whether enhancing PP2A activity...
There is no standardized method for assessing serum total mast cell tryptase (MCT) in anaphylaxis. The consensus equation (peak MCT should be>1.2× baseline tryptase+2 mg/L) has been proposed to interpret acute MCT in mast cell activation syndrome (MCAS). To validate consensus equation in a perioperative setting analyses of cases of suspected perioperative anaphylaxis during general anaesthesia...
Background
Atopic dermatitis (AD) is characterized by robust immune activation. Various T‐cell subsets, including Th2/Th22 cells, are increased in lesional and nonlesional skin. However, there is conflicting literature on the diversity of the T‐cell receptor (TCR) repertoire in lesional AD, and its relation to nonlesional skin remains unclear.
Methods
We performed high‐throughput deep sequencing...
The prevalence of allergic diseases and asthma has dramatically increased over the last decades, resulting in a high burden for patients and healthcare systems. Thus, there is an unmet need to develop preventative strategies for these diseases. Epidemiological studies show that reduced exposure to environmental bacteria in early life (eg, birth by cesarean section, being formula‐fed, growing up in...
Cytomegalovirus (CMV) IgG antibodies have been associated with inflammaging and immunosenescence. We aimed to assess the presence of CMV DNA in the blood of adult and elderly patients with bronchial asthma to establish potential association of CMV DNAemia with asthma and asthma characteristics. Eighty‐five elderly asthmatics, 74 younger asthma patients, and 114 age‐matched controls were recruited...
Background
Food allergies are a growing health problem, and the development of therapies that prevent disease onset is limited by the lack of adjuvant‐free experimental animal models. We compared allergic sensitization in patients with food allergy or Wiskott‐Aldrich syndrome (WAS) and defined whether spontaneous disease in Was−/− mice recapitulates the pathology of a conventional disease model and/or...
Background
Histamine is a key immunoregulatory mediator and can dampen proinflammatory responses via activation of histamine receptor 2 (H2R). The aim of this study was to determine the role of H2R in modulating lung inflammatory responses.
Methods
H2R was blocked using famotidine or activated using dimaprit in both the ovalbumin (OVA) and house dust mite extract (HDM) murine models of respiratory...
Background
Ragweed pollen represents a major allergy risk factor. Ragweed extracts contain five different isoforms of the major allergen Amb a 1. However, the immunological characteristics of Amb a 1 isoforms are not fully investigated. Here, we compared the physicochemical and immunological properties of three most important Amb a 1 isoforms.
Methods
After purification, the isoforms were physicochemically...
Background
Omalizumab is licensed for therapy in severe allergic asthma with an effect demonstrated after 8 weeks or longer treatment. As new applications for omalizumab demand precise knowledge of the onset of effects, the objective of this study was to determine the time course of the early (EAR) and late allergic reaction (LAR).
Materials and Methods
Ten patients (IgE>300 IU/mL and <700...
