BackgroundAllergic rhinitis (AR) is a widely diffused atopic disease that is hardly managed by conventional therapy, especially in the long-term. Fatty acids (FAs), which possess both anti-inflammatory and immunomodulatory properties, could be used to control AR symptoms.ObjectiveWe aimed at evaluating the benefits (efficacy in reducing symptoms and safety) of using an oral supplement containing FAs… Continue reading Multicentre, double-blind, randomized placebo-controlled trial to evaluate the therapeutic efficacy of #nutraceutical combination in the treatment of #allergic #rhinitis

The effect of #camel #milk on house dust mite allergen induced #asthma model in BALB/C mice
Camel milk has demonstrated robust immunomodulatory and anti-inflammatory properties in various clinical and experimental studies. However, no previous studies have characterized the cellular immunological effects of camel milk in the context of allergic asthma. Therefore, the present work aimed to evaluate the protective effects of camel milk in house dust mite induced asthma in mice,… Continue reading The effect of #camel #milk on house dust mite allergen induced #asthma model in BALB/C mice
#Skin damage signals mediate #allergic sensitization to spatially unlinked antigen
Our current understanding of immunity to pathogens suggests that anatomic coupling of antigens with danger signals is a required feature for the formation of immune memory. However, in the context of pathogen-independent inflammation, the stringency of this anatomical coupling is unclear. Here, we demonstrate that multiple modes of skin injury were sufficient to induce a… Continue reading #Skin damage signals mediate #allergic sensitization to spatially unlinked antigen
Gut #microbiota markers in early #childhood are linked to #farm living, pets in household and allergy
BackgroundChildren growing up on farms or with pets have a lower risk of developing allergy, which may be linked to their gut microbiota development during infancy MethodsChildren from the FARMFLORA birth cohort (N = 65), of whom 28 (43%) lived on a dairy farm and 40 (62%) had pets, provided fecal samples at intervals from… Continue reading Gut #microbiota markers in early #childhood are linked to #farm living, pets in household and allergy
#Antibiotic-driven #dysbiosis in early life disrupts indole-3-propionic acid production and exacerbates #allergic airway inflammation in adulthood
•Early-life antibiotics increase the risk of allergy in adulthood•Antibiotics cause short-term disruption of the microbiome and systemic metabolome•Dysfunctional mitochondria in the airway epithelium lead to exaggerated inflammation•Indole-3-propionic acid counters the detrimental effects of early-life antibioticsSummaryAntibiotic use in early life disrupts microbial colonization and increases the risk of developing allergies and asthma. We report that mice… Continue reading #Antibiotic-driven #dysbiosis in early life disrupts indole-3-propionic acid production and exacerbates #allergic airway inflammation in adulthood
Early childhood allergy linked with development of attention deficit hyperactivity disorder and autism spectrum disorder
BackgroundPrevious studies reported controversial results regarding the association between allergic disorders and attention deficit hyperactivity disorder (ADHD)/autism spectrum disorder (ASD). The aim of this article was to investigate whether allergic disorders are associated with ADHD/ASD in a large cohort of pediatric patients. MethodsA retrospective study using the pediatric (0–18 year) database (ICD-9-CM codes) of Clalit Health… Continue reading Early childhood allergy linked with development of attention deficit hyperactivity disorder and autism spectrum disorder
Assessment of #Allergic and #Anaphylactic Reactions to mRNA #COVID-19 Vaccines With Confirmatory Testing in a US Regional Health System
Objective To characterize the immunologic mechanisms underlying allergic reactions to these vaccines. Design, Setting, and Participants This case series included 22 patients with suspected allergic reactions to mRNA COVID-19 vaccines between December 18, 2020, and January 27, 2021, at a large regional health care network. Participants were individuals who received at least 1 of the… Continue reading Assessment of #Allergic and #Anaphylactic Reactions to mRNA #COVID-19 Vaccines With Confirmatory Testing in a US Regional Health System
An #Egg-Derived Sulfated N-Acetyllactosamine Glycan Is an Antigenic Decoy of Influenza Virus #Vaccines
Influenza viruses grown in eggs for the purposes of vaccine generation often acquire mutations during egg adaptation or possess different glycosylation patterns than viruses circulating among humans. Here, we report that seasonal influenza virus vaccines possess an egg-derived glycan that is an antigenic decoy, with egg-binding MAbs reacting with a sulfated N-acetyllactosamine (LacNAc). Half of… Continue reading An #Egg-Derived Sulfated N-Acetyllactosamine Glycan Is an Antigenic Decoy of Influenza Virus #Vaccines
UK probes whether #COVID-19 vaccine caused #allergic reactions
LONDON (AP) — Britain’s medical regulator warned Wednesday that people with a history of serious allergic reactions shouldn’t get the COVID-19 vaccine from Pfizer and BioNTech, and investigators looked into whether two reactions on the first day of the U.K.’s vaccination program were linked to the shot. The advice was issued on a “precautionary basis,”… Continue reading UK probes whether #COVID-19 vaccine caused #allergic reactions
