The Analytical Methods Working Party of the Association of Clinical Biochemists (ACB) established this Task Force to consider the measurement of total serum IgE and specific IgE. The aims were to give general guidance on available methods of assay; to survey commercial kits and 'in-house' methods; to investigate performance based on external Quality Assessment and independent evaluation, and to advise on criteria laboratories should consider before setting up IgE and specific IgE assays.

Introduction: A small number of soybean allergens [including Glycinin (11S) and β-Conglycinin (7S)] in the commercially available corn-soybean meal diet can still cause allergy in some weaned piglets, which may be the result of the interaction of genetic, and nutrition, but the specific mechanism is still unclear.
Methods: In this study, 20 allergic piglets and 20 non-allergic piglets were selected from 92 weaned piglets by skin sensitization tests, which were used to examine the whole sequence genome. The indicators related to humoral and cellular immunity, transcriptomics, and metabolomics analysis were determined by randomly selecting 5 boars in the allergic group and non-allergic group and then performing a validation .

The basophil activation test (BAT) has become a major cellular test for evaluating the allergenic activity of specific IgEs. The impact of the BAT is due to the ability of blood basophil granulocytes to present IgE on the high-affinity FcRI receptor and to mirror the mast cell response that elicits an acute allergic reaction. The BAT proved to be able to identify allergic patients at risk of reacting to a low dose of the allergen and/or developing life-threatening reactions and thus can significantly improve the current management of allergic patients.

Dengue, caused by the dengue virus (DENV), poses a significant global health challenge. Effective vaccines and treatments for dengue are lacking due to gaps in understanding its pathogenesis and mechanisms in severe cases. This study investigates the role of immunoglobulin E (IgE) in dengue, focusing on its potential association with virus neutralization and antibody-dependent enhancement (ADE) in DENV replication.

Background: The COVID-19 (SARS-CoV-2) epidemic has posed a major challenge to global public health, especially in children. Some children may experience secondary infection with Mycoplasma pneumoniae after SARS-CoV-2 infection, which has attracted widespread attention. Studies have shown that eosinophils play an important role in respiratory tract infections and are involved in regulating immune responses and inflammatory processes.

Background: Nephrotic syndrome is an immune-mediated renal disorder characterized by T-cell and B-cell dysfunctions with changes in immunoglobulin (Ig) levels and the IgG:IgM ratio. Therefore, this study aimed to determine whether the serum level of Igs can be considered as an index to predict the response to treatment and the prognosis of idiopathic nephrotic syndrome (INS) in children in the remission phase.
Methods: The study population consisted of 38 children with INS in the remission phase and 38 age- and sex-matched healthy children.
