IL-24 is a common and specific autoantigen of IgE in patients with chronic spontaneous urticaria Authors:   Schmetzer O1, Lakin E2, Topal FA2, Preusse P2, Freier D2, Church MK2, Maurer M2. 1 Department of Dermatology and Allergy, Charité-Universitätsmedizin Berlin, Berlin, Germany. Electronic address: oliver.schmetzer@charite.de. 2 Department of Dermatology and Allergy, Charité-Universitätsmedizin Berlin, Berlin, Germany. Abstract: BACKGROUND: The efficacy of omalizumab (anti-IgE) and increased IgE levels in patients with chronic spontaneous urticaria (CSU) suggest autoallergic mechanisms. OBJECTIVE: We sought to identify autoallergic targets of IgE in patients with CSU. METHODS: Serum samples of patients with CSU together with those of patients with idiopathic anaphylaxis and healthy control subjects (7 of each) were screened for IgE autoantibodies by using an array of more than 9000 proteins. Sera of 1062 patients with CSU and 482 healthy control subjects were...

Timing of Food Introduction and the Risk of Food Allergy Authors:   Ferraro V1, Zanconato S2, Carraro S3. 1 Women's and Children's Health Department, University of Padova, via Giustiniani 2, 35128 Padova, Italy. ferrarovalentina@hotmail.com. 2 Women's and Children's Health Department, University of Padova, via Giustiniani 2, 35128 Padova, Italy. stefania.zanconato@aopd.veneto.it. 3 Women's and Children's Health Department, University of Padova, via Giustiniani 2, 35128 Padova, Italy. silvia.carraro@unipd.it. Abstract: Given that the prevalence of pediatric IgE-mediated food allergies (FA) has followed a substantive increase in recent decades, nowadays, a research challenge is to establish whether the weaning strategy can have a role in FA prevention. In recent decades, several studies have demonstrated that delayed exposure to allergenic foods did not reduce the risk of FA, leading to the publication of recent guidelines which recommend against dela...

Advances in the pathogenesis representing definite outcomes in chronic urticaria. Authors:  Ensina LF1,2, Cusato-Ensina AP3, Cardona R4. 1 Federal University of São Paulo. 2 Hospital Sírio-Libanês. 3 CPAlpha Clinical Research Center, Brazil. 4 Universidad de Antioquia, Colombia. Abstract: PURPOSE OF REVIEW: We reviewed in this article, the recent advances in CSU physiopathology and potential clinical and laboratory biomarkers in CSU. RECENT FINDINGS: In addition to the central role of mast cells in urticaria physiopathology, increased interest in basophils has arisen. Recent data corroborate the autoimmunity pathway as one of the main pathways in mast cell activation. The association of inflammatory cytokines, heat shock proteins and staphylococcal infection with CSU are also reviewed. C-reactive protein, D-dimers, autologous serum skin test, IgE levels and FcεRI expression in basophils have shown their potential as biomarkers for disease duration, activity, sever...

Wheat allergy in patients with recurrent urticaria. Authors:  Xu YY1,2, Jiang NN1, Wen LP1,2, Li H1,2, Yin J1,2. 1 Department of Allergy, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, China. 2 Beijing Key Laboratory of Precision Medicine for Diagnosis and Treatment on Allergic Diseases, China. Abstract:  BACKGROUND: Clinical observation revealed that most of wheat-induced anaphylaxis (WIA)/wheat-dependent exercise-induced anaphylaxis (WDEIA) patients showed a history of recurrent urticaria. We aim to determine the association between recurrent urticaria and anaphylaxis in wheat allergy. METHODS: Population-based cohort study involved patients with WIA (n = 193, including WDEIA n = 104), recurrent urticaria (n = 177), non-wheat-related anaphylaxis (n = 584), atopic disease (excluding anaphylaxis, n = 221) and healthy control (n = 95) from 2009 to 2016. Detailed course of urticaria and anaphylaxis w...

Personalized Medicine and Pediatric Asthma. Authors: Pajor NM1, Guilbert TW2. 1 Department of Pediatrics, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue, MLC 7041, Cincinnati, OH 45229, USA. 2 Department of Pediatrics, University of Cincinnati, Cincinnati, OH, USA; Pulmonary Division, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue, MLC 7041, Cincinnati, OH 45229, USA. Electronic address: Theresa.guilbert@cchmc.org. Abstract: Asthma is a heterogeneous disorder described by a large number of clinical features. A growing body of literature on more specific asthma phenotypes provides evidence for a phenotype-based approach to management in which specific therapies are recommended based on patient and disease characteristics. This understanding, coupled with an increase in the number of available therapies for children with asthma, as well as emerging therapies and phenotypic markers, will allow for improved asthma management in the ...

Red meat allergy in children and adults Authors: Wilson JM1, Platts-Mills TAE. 1 Division of Allergy and Immunology, University of Virginia, Charlottesville, Virginia, USA. Abstract: PURPOSE OF REVIEW: To highlight recent advances in our understanding of the clinical features, prevalence, and pathophysiology of red meat allergy. RECENT FINDINGS: Allergic reactions to red (i.e. mammalian) meat have historically been considered rare and described primarily in young atopic children. It is now clear that red meat allergy is not uncommon in some parts of the world in other age groups. Strikingly, the majority of these cases relate to specific IgE to galactose-α-1,3-galactose, an oligosaccharide of nonprimate mammals. The mechanism of sensitization in this syndrome relates to bites of certain hard ticks and the clinical reactions often have a delay of 3 to 6 h. An additional form of red meat allergy relates to inhalant sensitization to mammalian proteins. The best characterize...

The clinical benefit of mepolizumab replacing omalizumab in uncontrolled severe eosinophilic asthma Authors: Kenneth R. Chapman  Frank C. Albers  Bradley Chipps  Xavier Muñoz  Gilles Devouassoux  Miguel Bergna  Dmitry Galkin  Jay Azmi  Dalal Mouneimne  Robert G. Price  Mark C. Liu Abstract: Background Mepolizumab and omalizumab are treatments for distinct but overlapping severe asthma phenotypes. Objective To assess if patients eligible for both biologics but not optimally controlled with omalizumab experience improved asthma control when switched directly to mepolizumab. Methods OSMO was a multicenter, open‐label, single‐arm, 32‐week trial in patients with ≥2 asthma exacerbations in the year prior to enrollment, despite receiving high‐dose inhaled corticosteroids and other controller(s), plus omalizumab (≥4 months). At baseline, patients with blood eosinophil counts ≥150 cells/μL (or ≥300 cells/μL in the prior year) a...

Authors:  Krol K1, Morgan MA1, Khurana S2. 1 Pulmonary and Critical Care Medicine, University of Rochester School of Medicine, University of Rochester Medical Center, 601 Elmwood Avenue, Box 692, Rochester, NY 14642, USA. 2 Pulmonary and Critical Care Medicine, Mary Parkes Center for Asthma & Pulmonary Care, University of Rochester School of Medicine, University of Rochester Medical Center, 601 Elmwood Avenue, Box 692, Rochester, NY 14642, USA. Electronic address: sandhya_khurana@urmc.rochester.edu. Abstract:  Respiratory symptoms are common reasons for patients to seek care and contribute significantly to use of health care resources. Identifying the underlying etiology of a respiratory symptom is key to management; yet, pinpointing the cause can be a challenge. Familiarity with the tools available to help discern between the various contributing etiologies is crucial in guiding mana...
