..., and autologous serum skin tests (ASSTs). The relationships between atopy, the demographic and clinical data of patients with CSU, and the response to ASST were analyzed in detail; the distribution of allergens in atopic CSU was also analyzed. Results: Atopy was confirmed in 48.9% of patients with CSU. Patients...

... proteins in GCr blood and eggs (including egg cases), respectively, and are possible high molecular mass allergens. Prior efforts to purify Vg/Vn yielded amounts too small for subsequent studies. In this study, we report the affinity purification of Vg/Vn from whole-body defatted GCr powder...

... in the subtropical and tropical regions characterized by high temperatures and high levels of humidity, which favour the wider occurrence of fungi in the environment. The presence of specific IgE antibodies directed against fungal allergens, which is one of the diagnostic criteria, proves the systemic nature...

... the influence of the COVID-19 pandemic on the allergen sensitization rate in patients with allergic diseases in central China. The results provide reliable epidemiological data for the prevention and control of allergic diseases during the COVID-19 epidemic. Methods: Data were collected from a total of 6,915...

...Katrine Baumann; Per Stahl Skov; Esben Eller; Bjarne Kristensen; Carsten Bindslev-Jensen Introduction: Detection of specific food allergens brought into circulation following ingestion is complicated by the minute amounts present in serum. We therefore aimed to assess the utility of selective...

...Zhi-Ling Zhu; Ying-Xing Wu; Zhu-Ping Zhang; Song Li Introduction: We explored the cross-reactivity among 19 common allergen sources and evaluated the influence of serum IgE concentrations and the number of sensitized allergens on the incidence of allergic symptoms. Methods: We conducted this cross...

...Benedetta Biagioni; Leonardo Tomei; Claudia Valleriani; Giulia Liccioli; Simona Barni; Lucrezia Sarti; Francesco Citera; Mattia Giovannini; Francesca Mori Background: Gibberellin-regulated proteins (GRPs, Peamaclein) are allergens recently identified in plant-derived food allergy (FA), and little...

... was to determine the factors affecting the skin reactivity to histamine and allergens and investigate whether it differs according to age in terms of reading time. Methods: A total of 500 patients, aged 4 months–18 years, were enrolled in the study. Wheal and flare reaction sizes were documented as the mean...

... and identification of new allergens. However, these studies have been almost restricted to Dermatophagoides spp. Although Blomia tropicalis has long been established as a clinically important source of allergens, a thorough proteomic characterization is still lacking for this dust mite. Objective: To increase...

... to gain insight into its causal allergens, we aimed to evaluate cellular and humoral immune responses to the recombinant salivary antigen Cte f 2 from the cat flea Ctenocephalides felis . Method: Sixty patients with PU and 27 healthy controls were included in this study. Specific IgE, IgG, IgG1, and IgG4...

... infections. To reduce the morbidity and transmission of helminth infections, the world health organization recommends preventive treatment of school children by providing mass drug administration (MDA) with albendazole. Here, we had an opportunity to evaluate the prevalence of skin reactivity to allergens...

...Kashinath Bhattacharya; Gaurab Sircar; Angira Dasgupta; Swati Gupta Bhattacharya The growing prevalence of allergy and asthma in India has become a major health concern with symptoms ranging from mild rhinitis to severe asthma and even life-threatening anaphylaxis. The “allergen repertoire...

.... Therefore ragweed is becoming domestic in non-invaded areas which in turn will increase the sensitization rate. So far 11 ragweed allergens have been described and, according to IgE reactivity, Amb a 1 and Amb a 11 seem to be major allergens. Sensitization rates of the other allergens vary between 10 and 50...

..., only a few of these are allergenic [ 16,17 ]. Within the proteome of DP, <0.1% of the proteins are allergens [ 18 ]. This may be due to the cellular location of a protein within an organism and/or the persistence and stability of a protein in the environment [ 18 ]. Many allergens are also members...

...June Yong Lee; Misuk Yang; Kyoung Yong Jeong; Da Woon Sim; Jin Hee Park; Kyung Hee Park; Jae-Hyun Lee; Jung-Won Park Background: Oaks are the most common trees in Korean forests, and Mongolian oak, Quercus mongolica , is the dominant species. However, no allergen has been characterized from...

...Hiroaki Okano; Takashi Fujimura; Norihiko Fukuoka; Takaharu Hayashi; Kazuo Nishikawa; Kazuhisa Ono; Seiji Kawamoto Background: A high level of house dust mite (HDM) allergens in a living environment is a risk factor for both sensitization to these allergens and asthmatic attacks. We previously...

... in adult patients with a previous diagnosis of non-AR was assessed. Material and Methods: Eighty-four patients with perennial nasal allergy symptoms but a negative skin prick test and specific IgE antibodies against common inhalant allergens were included in the study. Nasal provocation tests were...

...Christian Radauer The increasing number of available data on allergenic proteins demanded the establishment of structured, freely accessible allergen databases. In this review article, features and applications of 6 of the most widely used allergen databases are discussed. The WHO/IUIS Allergen...

...Geoffrey A. Mueller Allergy is defined as an inappropriate immune response to something normally considered harmless. The symptomatic immune response is driven by IgE antibodies directed against allergens. The study of allergens has contributed significantly to our understanding of allergic disease...
