Drug allergy (DA) remains a complex and unaddressed problem worldwide that often deprives patients of optimal medication choices and places them at risk for life‐threatening reactions. Underdiagnosis and overdiagnosis are common and due to the lack of standardized definitions and biomarkers. The true burden of DA is unknown, and recent efforts in data gathering through electronic medical records are...
The exponential growth of precision diagnostic tools, including omic technologies, molecular diagnostics, sophisticated genetic and epigenetic editing, imaging and nano‐technologies and patient access to extensive health care, has resulted in vast amounts of unbiased data enabling in‐depth disease characterization. New disease endotypes have been identified for various allergic diseases and triggered...
Objective
The aim of this study was to systematically review the evidence across studies that assessed DNA methylome variations in association with food allergy (FA).
Design
A systematic review of the literature and meta‐analysis were carried out within several databases. However, the risk of bias in the included articles was not evaluated.
Data sources
PubMed, Cochrane Database of Systematic...
The current monkeypox disease (MPX) outbreak constitutes a new threat and challenge for our society. With more than 55,000 confirmed cases in 103 countries, World Health Organization declared the ongoing MPX outbreak a Public Health Emergency of International Concern (PHEIC) on July 23, 2022. The current MPX outbreak is the largest, most widespread, and most serious since the diagnosis of the first...
Background
The diagnosis of allergic reactions to penicillins (AR‐PEN) is very complex as there is a loss of sensitization over time, which leads to negative skin tests (STs) and specific IgE in serum, and even to tolerance to the drug involved. However, STs may become positive after subsequent exposure to the culprit drug (resensitization), with the risk of inducing potentially severe reactions...
Hypersensitivity reactions to drugs are increasing worldwide. They display a large degree of variability in the immunological mechanisms involved, which impacts both disease severity and the optimal diagnostic procedure. Therefore, drug hypersensitivity diagnosis relies on both in vitro and in vivo assessments, although most of the methods are not well standardized. Moreover, several biomarkers can...
Background
Immediate drug hypersensitivity reactions (IDHRs) to clavulanic acid (CLV) have increased in the last decades due to a higher consumption alongside amoxicillin (AX). Due to its chemical instability, diagnostic procedures to evaluate IDHRs to CLV are difficult, and current in vitro assays do not have an optimal sensitivity. The inclusion of the specific metabolites after CLV degradation,...
Background
Diagnosis of food allergies is challenging, as combining information from specific IgE (sIgE)‐sensitization pattern and skin prick tests (SPTs) with clinical history is necessary for a personalized management of allergic patients. The aim of this study was to compare two molecular tests, the ImmunoCAP ISAC (ISAC) and the Allergy Explorer, version 2 (ALEX2) in the context of pollen food...
Background
The involvement of allergen‐specific (s)IgE in local allergic rhinitis (LAR) has been debated. Here, we investigate the effect of nasal allergen challenge with Dermatophagoides pteronyssinus (NAC‐DP) in mucosal and peripheral B‐cell subpopulations in LAR patients.
Methods
Nine LAR, 5 allergic rhinitis (AR), and 5 non‐atopic healthy control (HC) individuals were subjected to a 3‐day NAC‐DP...
Purpose
To investigate the association between the ganglion cell complex (GCC) thickness at early school‐age and prematurity and other neonatal factors.
Methods
Cross‐sectional study. The sample included very preterm children with gestational age (GA) below 32 weeks or birthweight below 1500 g enrolled in a follow‐up program (n = 101) and a comparison group of term‐born children (n = 49). Ganglion...
Non‐steroidal anti‐inflammatory drugs (NSAIDs) and other eicosanoid pathway modifiers are among the most ubiquitously used medications in the general population. Their broad anti‐inflammatory, antipyretic, and analgesic effects are applied against symptoms of respiratory infections, including SARS‐CoV‐2, as well as in other acute and chronic inflammatory diseases that often coexist with allergy and...
Background
mRNA‐based COVID‐19 vaccines have been reported to induce hypersensitivity reactions (HSR) in a small number of individuals. We aimed to evaluate the real‐world incidence of the BNT162b2 mRNA COVID‐19 vaccine HSR and to determine the value of the basophil activation test (BAT) in the allergological workup of patients reporting these reactions.
Methods
We prospectively enrolled patients...
Background
Nonimmediate (delayed)‐allergic reactions to penicillins are common and some of them can be life‐threatening. The genetic factors influencing these reactions are unknown/poorly known/poorly understood. We assessed the genetic predictors of a delayed penicillin allergy that cover the HLA loci.
Methods
Using next‐generation sequencing (NGS), we genotyped the MHC region in 24 patients with...
Background
As in many fields of medical care, the coronavirus disease 2019 (COVID‐19) resulted in an increased uncertainty regarding the safety of allergen immunotherapy (AIT). Therefore, the European Academy of Allergy and Clinical Immunology (EAACI) aimed to analyze the situation in different countries and to systematically collect all information available regarding tolerability and possible amendments...
