Type I hypersensitivity is a major problem in public health, often requiring numerous investigations which aim to diagnose atopy and identify the causative allergen. Among these investigations, several blood tests, mostly using immunoenzymatic methods, can be performed to measure total and specific IgE levels. Type I hypersensitivity can also be investigated with assays which quantitate several mediators released after cellular activation induced by allergens.

To investigate the characteristics of type 2 inflammation in patients with nocturnal asthma, and analyze the improvement of asthma symptoms after the use of inhaled corticosteroids (ICS) combined with different long-acting bronchodilators. Data of 231 asthma patients who first visited the Respiratory and Critical Care Medical Clinic of Nanfang Hospital of Southern Medical University from January 2020 to June 2023 and had positive bronchodilator tests (BDT), were retrospectively analyzed. These patients were divided into nocturnal asthma group and non-nocturnal asthma group based on the presence or absence of nocturnal symptoms.

Background: Choosing effective devices (inhaled corticosteroid [ICS]-long-acting β2 agonist [LABA] combination inhalers) as maintenance treatment is critical for managing patients with asthma. We aimed to compare ICS/LABA combination efficacy, safety, and adherence across inhaler types and components in patients newly diagnosed with asthma.
Methods: Utilizing South Korea's National Health Insurance Service data, we conducted a population-based cohort study involving patients aged 18-80 years, newly diagnosed with asthma who received ICS/LABA combination therapy between January 2016 and December 2020.

Egg allergen-specific T-cell and cytokine responses in healthy and egg-allergic children naturally tolerating baked egg.

Department of Microbiology, Immunology and Transplantation, Allergy and Immunology Research Group, KU Leuven, Leuven, Belgium.
Background: Type 1 regulatory T (Tr1) cells are critical players in maintaining peripheral tolerance, by producing high IL-10 levels in association with inducible T-cell co-stimulator (ICOS) expression. Whether these cells play a role in naturally acquired baked egg tolerance is unknown.
Objectives: Evaluate frequencies of egg-responsive Tr1 and Th2 cells in egg-allergic children that naturally acquired baked egg tolerance (BET) versus non-egg-allergic (NEA) children.

Pathophysiologically, drug hypersensitive reactions (DHRs) are classified into four types: type I, immediate reactions, and types II, III, and IV, non-immediate reactions. They are further categorized as severe or non-severe based on clinical severity. Genetic predisposition and viral reactivation are cofactors of severe DHR type IV.
