Patients with chronic spontaneous urticaria (CSU) are widely held to often have other autoimmune disorders, including autoimmune thyroid disease. Here, we systematically evaluated the literature on the prevalence of thyroid autoimmunity in CSU and vice versa. There is a strong link between CSU and elevated levels of IgG antithyroid autoantibodies (AAbs), with most of a large number of studies reporting...
Ocular allergy (OA) includes a group of common and less frequent hypersensitivity disorders frequently misdiagnosed and not properly managed. The diagnosis of OA is usually based on clinical history and signs and symptoms, with the support of in vivo and in vitro tests when identification of the specific allergen is required. To date, no specific test is available for the diagnosis of the whole spectrum...
Background
The impact of basophils on asthma pathogenesis remains largely unexplored, particularly in humans. Here, we evaluated the frequencies and activation status of basophils in the sputum of adult asthmatic patients and related our findings to other parameters of eosinophilic airway inflammation.
Methods
We enrolled 44 adult asthmatic patients who were being treated with inhaled corticosteroids...
Allergic rhinitis often impairs social life and performance. The aim of this cross‐sectional study was to use cell phone data to assess the impact on work productivity of uncontrolled rhinitis assessed by visual analogue scale (VAS). A mobile phone app (Allergy Diary, Google Play Store and Apple App Store) collects data from daily visual analogue scales (VAS) for overall allergic symptoms (VAS‐global...
Background
The production of IgE molecules specific to the carbohydrate galactose‐α‐1,3‐galactose (alpha‐gal) is known to induce delayed anaphylaxis against mammalian meat. Tick bites constitute the primary sensitization source, as ticks transfer alpha‐gal in their saliva to a host during a bite. The reported prevalence of alpha‐gal‐specific IgE (alpha‐gal‐sIgE) positivity varies between different...
Treatment with SQ (standardised quality) house dust mite sublingual tablet for 1 year resulted in a decreased probability of having an allergic rhinitis (AR) exacerbation day (from 11% [placebo] to 5% [SQ house dust mite sublingual tablet]) and an increased probability of having a mild AR day (from 16% [placebo] to 34% [SQ house dust mite sublingual tablet]).
Background
Saliva and muscle‐derived mosquito allergens have been purified and characterized. However, the complete set of allergens remains to be elucidated. In this study, we identified and characterized IgE‐binding proteins from the mosquito species Aedes aegypti.
Methods
Serum was obtained from 15 allergic individuals with asthma and/or rhinitis and sensitized to mosquito. IgE binding was determined...
The aim of this study was to investigate possible effects of landscape design on the IgE sensitization profile toward inhalant allergens in patients with respiratory allergy from Uzbekistan where green areas have been changed during the last two decades by a State program. Sera from two different generations of Uzbek (n=58) and, for control purposes, from two generations of Austrian (n=58) patients...
Background
Prostaglandin D2 (PGD2) is primarily produced by mast cells and is contributing to the nasal symptoms including nasal obstruction and rhinorrhea.
Objective
This study aimed to evaluate the efficacy and safety of a novel PGD2 receptor 1 (DP1) antagonist, ONO‐4053, in patients with seasonal allergic rhinitis (SAR).
Methods
This study was a multicenter, randomized, double‐blind, parallel‐group...
Background
Occupational respiratory diseases in workers of peach tree crops have been reported punctually and have been associated with sensitization to proteins present in both pollen and leaf tree. We report the study of 37 workers with respiratory symptoms related to occupational exposure to peach trees.
Methods
Prick tests and specific IgE determinations were performed with extracts from leaves...
Background
Staphylococcus aureus (S. aureus) carriage and sensitization to S. aureus enterotoxins (SEs) have been associated with allergic diseases. From the Tromsø Study Fit Futures 2, we have previously shown an association between S. aureus carriage and severe allergic disease and allergic multimorbidity. However, the role of S. aureus carriage and SE sensitization on allergic multimorbidity and...
Background
Interleukin (IL)‐33 is implicated in the pathophysiology of asthma and allergic diseases. However, our knowledge is limited regarding how IL‐33 release is controlled. The transcription factor nuclear factor‐erythroid‐2‐related factor 2 (Nrf2) plays a key role in antioxidant response regulation.
Objective
The goal of this project was to investigate the role of cellular oxidative stress...
Background
T helper type 9 (Th9) cells, a subpopulation of CD4+ T cells, play a critical role in the pathogenesis of allergic airway inflammation. However, it remains unknown whether mTORC2 regulates Th9 differentiation or function during allergic inflammation.
Methods
T‐cell‐specific Rictor‐deficient mice, a mouse model of allergic airway inflammation induced by ovalbumin (OVA) sensitization and...
Sputum basophil numbers are increased in allergic asthmatics, but it is unclear what role airway basophils play in “TH2‐low” asthma phenotypes. Using flow cytometry, we found that basophils were significantly increased in all asthmatics (n=26) compared with healthy controls (n=8) (P=0.007) with highest levels observed in eosinophilic asthma (EA); median 0.22%, IQR 0.11%‐0.47%; n=14) compared with...
The number of patients suffering from allergic asthma and rhinoconjunctivitis has increased dramatically within the last decades. Allergen‐specific immunotherapy (AIT) is the only available cause‐oriented therapy so far. AIT reduces symptoms, but has also a disease‐modifying effect. Disadvantages are a long‐lasting procedure, and in a few cases potential systemic adverse reactions. Encapsulation of...
