Immediate drug hypersensitivity reactions (IDHRs) constitute a significant health problem that may be compounded by consequences of diagnostic error. In daily practice, IDHR diagnostic work up starts with drug-specific skin testing and/or quantification of specific IgE (sigE) antibodies in serum. Here we critically review the performance, i.e. potential and limitations of sIgE to β-lactam antibiotics (β-LABs), curarizing neuromuscular blocking agents (NMBAs), opiates and (semi)synthetic opioids, fluoroquinolones (FQs), poppy seed (papaver somniferum), chlorhexidine and finally Hevea latex. Quintessence of these studies is clear. Quantification of these drug-specific sIgE should not be used in isolation to document or exclude diagnosis of an IDHR. False negative results entail the risk for subsequent potentially life-threatening anaphylaxis upon re-exposure. False positive results lead to erroneous avoidance and unnecessary substitutions and fails to identify the true etiology.

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.

This mini-review examines the emerging role of the gut microbiome in influencing food allergen cross-reactivity. It specifically focuses on how microbial diversity, antigens, and metabolites impact IgE-mediated allergic responses. Cross-reactivity occurs when structurally similar food and microbial antigens trigger hypersensitivities, affecting millions of people worldwide.
