Abstract: BACKGROUND: Literature on the efficacy of azathioprine in antihistamine refractory chronic spontaneous urticaria (CSU) is limited. OBJECTIVE: To compare the efficacy and safety of azathioprine with respect to cyclosporine in the treatment of refractory CSU. METHODS: In this prospective, randomized, active-controlled, non-inferiority study, 80 patients of refractory CSU were administered either cyclosporine (group A, n ​= ​40) or azathioprine (group B, n ​= ​40) for 90 days and followed up for further 90 days. The treatment

Twelve-year follow-up study after endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyposis Authors:   Lien Calus1, Nicholas Van Bruaene1, Cedric Bosteels1, Sarah Dejonckheere1, Thibaut Van Zele1, Gabrielle Holtappels1, Claus Bachert1,2 and Philippe Gevaert1* 1 Upper Airways Research Laboratory, Department of Otorhinolaryngology, Ghent University Hospital, De Pintelaan 185, 9000 Ghent, Belgium Abstract: Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a therapeutic challenge because of the high recurrence rate. Surgical intervention should be considered in patients who fail to improve after medical treatment. We monitored recurrence and revision surgery over 12 years after endoscopic sinus surgery in CRSwNP patients. Methods: In this prospective cohort study, 47 patients with CRSwNP, who underwent primary or revision extended endoscopic sinus surgery, were followed. Clinical symptoms and total nasal endoscopic polyp score we

Mast Cell Activation Syndrome and Mastocytosis: Initial Treatment Options and Long-Term Management. Authors: Castells M1, Butterfield J2. 1 Division of Rheumatology, Allergy, and Immunology, Brigham and Women's Hospital Mastocytosis Center, Boston, Mass. Electronic address: mcastells@bwh.harvard.edu. 2 Mayo Clinic Program for Mast Cell and Eosinophil Disorders, Mayo Clinic, Rochester, Minn. Abstract: Patients with clonal mast cell activation syndromes (MCAS) including cutaneous and systemic mastocytosis (SM) may present with symptoms of mast cell activation, but in addition can have organ damage from the local effects of tissue infiltration by clonal mast cells. Patients with nonclonal MCAS may have chronic or episodic mast cell activation symptoms with an increase in serum tryptase and/or urinary metabolites of histamine, prostaglandin D2, and leukotrienes. Symptoms of MCAS and SM can be managed by blockade of mediator receptors (H1 and H2 antihistamines, leukotriene r

An evaluation of fevipiprant for the treatment of asthma: a promising new therapy? Authors: Murillo JC1, Dimov V2, Gonzalez-Estrada A3. 1 a Division of Allergy, Asthma, and Clinical Immunology , Mayo Clinic , Scottsdale , Arizona , USA. 2 b Department of Allergy and Clinical Immunology , Cleveland Clinic , Weston , Florida , USA. 3 c Division of Pulmonary, Allergy, and Sleep Medicine , Mayo Clinic , Jacksonville , Florida , USA. Abstract: Asthma is a heterogeneous disease characterized by chronic airway inflammation that affects more than 230 million people worldwide. Current guidelines recommend an escalating stepwise decision model for the management of asthma. However, disease control continues to be a challenge, particularly in patients with severe asthma. Biologics have proven to be an effective add-on treatment especially in eosinophilic or type 2 airway disease. Comparatively, pre-biologics may represent a successful novel therapy. Fevipiprant (QAW039) is a selectiv

Detection of serum and salivary IgE and IgG1 immunoglobulins specific for diagnosis of food allergy. Authors:  Nunes MPO1, van Tilburg MF1, Tramontina Florean EOP1, Guedes MIF1. 1 Laboratory of Biotechnology and Molecular Biology, State University of Ceará, Fortaleza, Ceará, Brazil. Abstract: Given the growing incidence and prevalence of life-threatening food allergies, health concerns have raised new perspectives for in vivo and in vitro diagnostic methodologies, pointing to saliva as a promising material, already used to diagnose other pathologies. Based on the above considerations, this study aimed to verify the possible use of saliva for the detection of IgE and IgG1 in the diagnosis of food allergy. This was a randomized, cross-sectional clinical study with a quantitative approach, developed at a hospital referral center in allergy in the state of Ceará, from January to July 2015. The sample consisted of 36 children of both sexes, aged between 1 and 60 months, with a di

IgE Mediated Autoallergy against Thyroid Peroxidase – A Novel Pathomechanism of Chronic Spontaneous Urticaria? Authors: Altrichter S1, Peter HJ, Pisarevskaja D, Metz M, Martus P, Maurer M. 1 Department of Dermatology and Allergy, Allergie-Centrum-Charité/ECARF, Charité-Universitätsmedizin Berlin, Berlin, Germany Abstract: BACKGROUND: Chronic spontaneous urticaria (csU), which is characterized by recurrent episodes of mast cell-driven wheal and flare-type skin reactions, is often associated with elevated total IgE levels and thyroid autoimmunity. We speculate that some csU patients express IgE autoantibodies against thyroid antigens such as thyroid peroxidase (TPO), which could bind to skin mast cells and induce their activation. METHODS: We developed and used a site-directed human IgE capture ELISA to quantify IgE-anti-TPO. We used this assay and investigated csU patients (n = 478) and healthy control subjects (n = 127) for IgE-anti-TPO and then assessed IgE-anti-TP

New Directions in Pediatric Asthma Authors:  Bacharier LB1, Guilbert TW2. 1 Department of Pediatrics, Washington University School of Medicine in St. Louis, Campus Box 8116, 660 South Euclid Avenue, St Louis, MO 63110, 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: Childhood asthma affects many children placing them at significant risk for health care utilization and school absences. Several new developments relevant to the field of pediatric asthma have occurred over the last 5 years; yet, there is much more to learn. It is poorly understood how to prevent the disease, optimally address environmental challenges, or effectively manage poor adherence. Moreover, it is not clear how to customize therapy by asthma phenotype, age group, high risk groups, or seve
