Allergic rhinitis is associated with elevated serum IgE levels. IgE response is mediated by the high-affinity IgE receptor (FcεRI), which is polymorphic. Studies analyzing the association between allergic rhinitis and FcεRI variants have been conducted with controversial results. The objective of this study is to analyze, in 1,041 individuals, the putative clinical association of allergic rhinitis with common polymorphisms in FcεRI subunits genes. These SNPs included FECR1A rs2494262, rs2427837 and rs2251746; FECR1B rs1441586, rs569108 and rs512555; FCER1G rs11587213, rs2070901 and rs11421. Statistically significant differences were observed for the FCER1B rs569108 and rs512555 polymorphisms frequencies when comparing patients with allergic rhinitis without asthma and controls. The OR (95% CI) value for the 237Gly allele (rs569108) is equal to 0.26 (0.08-0.86, P = 0.017) and for the G allele (rs512555) it is equal to 0.27 (0.08-0.88, P = 0.020). These two SNPs are linked (D' = 1.0, LOD = 56.05). Also observed was a statistically significant trend towards lower IgE values among allergic rhinitis patients with variant alleles for both SNPs. In conclusion, in patients with allergic rhinitis without asthma, the FCER1B rs569108 and rs512555 polymorphisms are associated with increased risk of developing allergic rhinitis and with lower IgE levels.

Background: Allergic rhinitis (AR) represents a persistent inflammatory condition affecting the upper respiratory tract, characterized by abnormal initiation of the immunoglobulin E (IgE)-mediated cascade. Follicular helper T (Tfh) cells and regulatory T (Tfr) cells are pivotal in orchestrating the development of IgE production in AR patients. IL-35, an anti-inflammatory cytokine, secreted by various cellular subpopulations.

Background: The incidence of allergic diseases has been increasing in Japan. In particular, a serious decline in the age of onset of allergic rhinitis has been observed. Passive smoking from parental smoking has a significant impact on children's health; however, it is difficult to restrict smoking in the home.

Asthma and allergic rhinitis (AR) are common disorders of the respiratory tract that often coincide. Control of AR symptoms can improve asthma outcomes in patients with co-existing diseases. Our aim is to produce a systematic review of the effectiveness of conventional anti-AR medication for asthma outcomes in patients with both diseases.

Background: Allergic rhinitis (AR) is a prevalent chronic inflammatory condition that significantly impacts patient quality of life and poses a substantial public health burden. Recent advancements in metabolomics have facilitated a deeper understanding of the metabolic pathways involved in AR, offering potential for new biomarkers and therapeutic targets.
Objective: This article aims to conduct a systematic review and meta-analysis of clinical studies summarizing the metabolomic profiles of allergic rhinitis (AR) to gain deeper insights into the metabolic changes and pathological processes underlying AR.

Objective: To investigate the diagnostic value of immunoglobulin E (IgE), fractional of exhaled nitric oxide (FeNO), and peripheral blood eosinophils (EOS) in adult bronchial asthma and to analyze their relationship with asthma severity.
Methods: A retrospective analysis was conducted on 336 patients diagnosed with bronchial asthma and admitted to Xi'an Fourth Hospital from January 2022 to January 2024, forming the asthma group. Additionally, another 127 healthy subjects were selected as the non-asthmatic control group.
