Gao YQ, Seah JJ, Wang ML, Tang QP, Wang DY, Bi XY, Han HW, Zhang TS, Ma J. An unusually high prevalence of allergic rhinitis at high altitudes in 6-7 year old children - An epidemiological study. World Allergy Organ J 2024; 17:100887. [PMID: 38742158 PMCID: PMC11089395 DOI: 10.1016/j.waojou.2024.100887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 02/18/2024] [Accepted: 02/21/2024] [Indexed: 05/16/2024] Open
Abstract
Objectives To compare the epidemiology and disease patterns of allergic rhinitis (AR) at 2 different altitudes in children aged 6-7 years, and subsequently to compare with and augment data from international studies. Materials and methods This is a multistage, clustered and stratified random sample study. The study area comprises 2 distinct areas within Yunnan Province, China. Low altitude was represented by Xishuangbanna Prefecture (XB), while high altitude was represented by Diqing Prefecture (DiQ). Each study area was subdivided into 3 sub-areas, and children aged 6-7 years were randomly sampled based on proportion-weighted sampling. The area studied includes the well-known area of Shangri-La city. Questionnaires were distributed and jointly completed by study participants and their parents or guardians, under the guidance of professional medical staff. Results 2796 valid questionnaires out of 2933 distributed were obtained (survey response rate 95.3%). The prevalence of AR is statistically significantly higher at high altitude (DiQ, 36.0%, 95%CI 33.2-38.8) as compared to low altitude (XB, 19.7%, 95%CI 17.8-21.6) (p < 0.001). Both areas studied had a greater prevalence of AR compared to international data. In both XB and DiQ, male gender, history of early antibiotic use, urban place of birth and place of residence, presence of smokers within the same household, family history of allergic diseases (such as atopic dermatitis), as well as higher parental educational level were all associated with a higher prevalence of AR (p < 0.05). In DiQ, the prevalence of AR in Han ethnicity was greater than that of ethnic minorities (p < 0.05). In XB, being a single child was associated with an increased prevalence of AR compared to those who had siblings (p < 0.05). Conclusion Our study found that the prevalence of AR is relatively greater at higher altitudes. Genetic and environmental factors both play an important role in the pathogenesis of AR. While altitude may be an important environmental factor, confounding factors may include humidity, temperature and distribution pattern of common aeroallergens.

Association of interleukin-12B rs6887695 with susceptibility to allergic rhinitis. Immunol Res 2021; 69:189-195. [PMID: 33834388 DOI: 10.1007/s12026-021-09189-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 03/30/2021] [Indexed: 10/21/2022]
Abstract
Interleukin-12 (IL-12) is a heterodimeric cytokine encoded by two separate genes, IL12A and IL12B, which may play a regulatory role in allergen-induced inflammation through CD4+ T-cell subsets polarization. The aim of this study was to investigate the association of single-nucleotide polymorphisms (SNPs) in the IL12B gene with susceptibility to allergic rhinitis (AR). We performed a case-control study including 130 AR patients and 130 healthy controls to evaluate the possible association between IL12B gene SNPs (rs3212227, rs6887695) and the risk of AR using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Our results showed no significant association between IL12B rs3212227 A > C polymorphism with AR. In contrast, the GC genotype of rs6887695 G > C was associated with susceptibility to AR in comparison with the GG genotype (p = 0.049, OR = 1.684, 95% CI: 1.002-2.83). We also observed a statistically significant difference in the additive model (GC versus GG + CC, p = 0.03, OR = 1.705, 95% CI: 1.040-2.794) for SNPs rs6887695. Furthermore, haplotypes analysis demonstrated that C-C haplotype was associated with an increased risk of AR (p = 0.01, OR = 1.845, 95% CI: 1.114-3.057). Our findings suggest that IL12B rs6887695 polymorphism may be a potential biomarker for susceptibility to AR in an Iranian population.

Abstract
Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2-3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of Journal Articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Abstract
BACKGROUND Allergic rhinitis (AR) is a highly prevalent chronic inflammatory disease affecting nearly 40% of the children in Taiwan. Genetic susceptibility may interact with specific environmental factors leading to allergic disease development. METHODS To assess the interactions between catalase gene promoter polymorphisms and environmental factors on the risk of AR, we conducted a case-control study in Taiwan. Data on AR and environmental factors were collected from 800 children using the ISSAC questionnaire. The case group consisted of 263 children with AR, and the control group consisted of =537 healthy children. Genotyping was performed for rs1001179 and rs769214 polymorphisms, and environmental exposure was assessed using four indicators including dwelling visible molds, mold odor, moisture on surfaces, and water damage. RESULTS We found that the presence of visible molds, mold odor, and moisture was associated with AR. An apparent joint effect of the GG genotype and mold odor, compared with the AA and AG combined genotypes and without any exposure indicator (adjusted odds ratio [OR] = 1.95 [95% confidence interval (CI) = 1.20, 3.18]; interaction adjusted odds ratio = 2.59 [95% CI = 1.27, 5.30]), was observed. CONCLUSIONS Our findings suggest that gene-environment interactions between the catalase polymorphism rs769214 and mold odor may play an important role in childhood AR development.

Abstract
Allergic rhinitis (AR) is a common inflammatory disease of the upper airway. Recent evidence suggests that gene‑gene interactions between tumor necrosis factor receptor superfamily 4 (TNFSF4) and B cell lymphocyte kinase (BLK) may have a synergistic effect on T and B cells in determining immunologic aberration, via the nuclear factor‑κB pathway. The present study was performed to evaluate the potential association between specific single nucleotide polymorphisms (SNPs) in the TNFSF4 and BKL genes with susceptibility to AR in Chinese subjects. A population‑based case‑control study was performed in 600 Chinese AR patients and 700 controls. Blood was drawn for DNA extraction, and 9 SNPs (6 in TNFSF4 and 3 in BKL genes) were selected and genotyped. The TNFSF4 SNPs rs1234314 and rs1234315, and the BLK SNPs rs13277113 and rs1600249 were observed to occur in different frequencies between the AR patients and the controls. The CC (rs1234314, rs1234315) and AA (rs1600249, rs13277113) genotypes provided protective effects against AR, whereas the AG (rs13277113) genotype presented a risk factor for AR. The haplotypes ACC in the rs1234313‑rs1234314‑rs1234315 block and GA in the rs2254546‑rs13277113 block significantly decreased the risk of AR, whereas the GGT and AG haplotypes served protective roles. SNP interaction analysis further indicated that there may be synergistic effects among the selected sets of polymorphisms. The present study suggests a novel association between specific TNFSF4 and BLK gene polymorphisms and AR risk, highlighting their potential utility as genetic biomarkers for AR susceptibility in a Chinese Han population.

Abstract
The prevalence of allergic rhinitis (AR) and asthma has been increasing, and the comorbidity rates of these diseases are very high. Here, 176 AR patients, 124 patients with comorbid AR and asthma (AR-A) and 206 healthy Chinese children as controls were included in a case-control study. Six single-nucleotide polymorphisms (SNPs), miR-146a (rs2910164, rs57095329 and rs6864584), miR-196a2 (rs11614913), miR-499 (rs3746444) and miR-149 (rs2292832), were genotyped. The prevalence of homozygous miR-149 (rs2292832) CC genotype and C allele were considerably increased in AR and AR-A patients, compared with the controls. AR-A group showed higher frequencies of CC genotype and C allele of rs2292832 than AR group. No significant difference in the genotypic and allelic frequencies of other miRNA SNPs was found between the groups. MiR-149 levels in peripheral blood mononuclear cells (PBMCs) were significantly lower in CC (variant type) cases compared with TT (wild-type) cases. In further experiments, PBMCs obtained from the healthy controls with CC, CT and TT genotypes were stimulated by house dust mite extracts, which led to a significant decrease in the levels of miR-149 in PBMCs obtained from CC and TT individuals. This decrease was more pronounced in CC compared with TT cases. Our results demonstrate that miR-149 rs2292832 variant is not only strongly associated with AR and AR-A, but it may lead to an increase in the susceptibility to allergies following the stimulation with an allergen, through the changes in miR149 expression. Additionally, AR patients with CC genotypes were shown to be more susceptible to asthma.

Abstract
BACKGROUND Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Protein tyrosine phosphatase non-receptor 22 encoded by PTPN22 gene and cytotoxic T-lymphocyte associated 4 encoded by Ctla4 gene are associated with autoimmune diseases. PURPOSE This study was performed to evaluate the potential association of PTPN22 and Ctla4 single nucleotide polymorphisms (SNPs) with AR in a Chinese Han population. METHODS A case-control study was performed in 783 Chinese AR patients and 811 healthy controls. Three SNPs in PTPN22 gene (rs2488457, rs1310182, and rs3789604) and 6 SNPs in Ctla4 gene (rs3087243, rs231779, rs11571302, rs11571315, rs231725, and rs35219727) were detected using a polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). RESULTS For PTPN22 gene, a significantly decreased prevalence of the rs2488457 CC genotype and C allele was found in AR patients. The frequencies of the rs1310182 CC genotype, CT genotype, and C allele were significantly associated with the risk of AR. For Ctla4 gene, a significantly increased prevalence of the rs11571302 AA genotype, CA genotype and A allele was noted in AR patients. CONCLUSION SNPs of PTPN22 and Ctla4 genes are significantly associated with the risk of AR in the Chinese Han population.

Abstract
Interleukin (IL)-12B is a key regulator in the protection against allergic reaction induced by various allergens in patients with allergic rhinitis (AR). This study was performed to investigate the associations between single nucleotide polymorphisms in the IL-12B gene and AR in a Chinese Han population. A total of 543 patients with AR and 600 healthy controls were genotyped for IL-12B/rs6887695, rs10045431, rs3212227, rs3212217, and rs2082412 using polymerase chain reaction (PCR) restriction fragment length polymorphism and PCR direct sequencing. The expression of IL-12B mRNA in peripheral blood mononuclear cells (PBMCs) obtained from normal controls was detected by quantitative real-time PCR. Levels of interferon (IFN)-γ and IL-4 in culture supernatants were measured by enzyme-linked immunosorbent assay. The frequencies of the rs3212227 genotype with the CC and C alleles were higher in patients with AR (p c = 8.55 × 10(-4); p c = 4.20 × 10(-4), respectively) than in normal controls. After peptidoglycan stimulation in PBMCs, IL-12 mRNA expression was reduced in healthy carriers of the CC genotype of rs3212227. Additionally, decreased production of IFN-γ was observed in patients having the CC genotype as compared with that in patients having the AC and AA genotypes. In contrast, IL-4 expression was higher in patients with the CC genotype than in patients with the other two genotypes. The IL-12B gene was involved in mediating susceptibility to AR.

Abstract
Atopic dermatitis (AD), food allergy, allergic rhinitis, and asthma are common atopic disorders of complex etiology. The frequently observed atopic march from early AD to asthma, allergic rhinitis, or both later in life and the extensive comorbidity of atopic disorders suggest common causal mechanisms in addition to distinct ones. Indeed, both disease-specific and shared genomic regions exist for atopic disorders. Their prevalence also varies among races; for example, AD and asthma have a higher prevalence in African Americans when compared with European Americans. Whether this disparity stems from true genetic or race-specific environmental risk factors or both is unknown. Thus far, the majority of the genetic studies on atopic diseases have used populations of European ancestry, limiting their generalizability. Large-cohort initiatives and new analytic methods, such as admixture mapping, are currently being used to address this knowledge gap. Here we discuss the unique and shared genetic risk factors for atopic disorders in the context of ancestry variations and the promise of high-throughput "-omics"-based systems biology approach in providing greater insight to deconstruct their genetic and nongenetic etiologies. Future research will also focus on deep phenotyping and genotyping of diverse racial ancestry, gene-environment, and gene-gene interactions.

Abstract
BACKGROUND Asthma and allergic rhinitis (AR) frequently occur as comorbid diseases of the upper airways. Single-nucleotide polymorphisms (SNPs) in the TNFSF4 and FAM167A-BLK genes have recently been shown to be associated with various immune-related disorders. OBJECTIVE Our aim was to determine whether TNFSF4 or FAM167A-BLK polymorphisms confer genetic susceptibility to asthma and AR in a Han Chinese population. METHODS We performed a case-control study of 290 asthmatic children and 252 healthy controls. Nine SNPs in the TNFSF4 region (rs1234313, rs1234314, rs1234315, rsl 2039904, rs844648 and rsl 0912580) and the FAM167A-BLK region (rs2254546, rs13277113 and rs1600249) were detected using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. RESULTS This study revealed that three SNPs in TNFSF4 (rsl 234313, rsl 234314 and rsl 234315) and two SNPs in FAM167A-BLK (rs2254546 and rsl 600249) were significantly correlated with asthma and AR, while SNP rsl600249 was associated with asthma without allergic rhinitis as a risk factor. Further, we demonstrated synergistic effects between the TNFSF4 and FAM167A-BLK SNPs. CONCLUSION This study supports that the SNPs in TNFSF4 and FAM167A-BLK may be involved in asthma and AR gene risk in the Han Chinese cohort.

Abstract
Objective: The interleukin-23 receptor (IL-23R) has been shown to be associated with autoimmune diseases in many different populations. This study aimed to investigate the association between IL-23R gene polymorphism and susceptibility to Hashimoto's thyroiditis (HT) in Chinese Han population of Shandong. Methods: A case–control cohort study was performed in 145 HT patients from First People's Hospital of Jining between February 2010 to October 2013 and 150 healthy controls. Two single nucleotide polymorphisms located in the promoter region of IL-23R gene (rs17375018 and rs7517847) were examined by polymerase chain reaction-restriction fragment length polymorphism analysis. Hardy-Weinberg equilibrium was performed using the Chi-square test. Genotype frequencies were estimated by direct counting, and allele and genotype frequencies between patients and controls were analyzed by the Chi-square test. Results: The rs17375018 GG genotype and the G allele were significantly increased in HT patients compared with healthy controls (P = 0.034 and P = 0.013, respectively). No association was identified between HT patients and healthy controls in rs7517847. Conclusion: The study demonstrated that polymorphism of IL-23R gene rs17375018 is highly associated with HT in Chinese Han population of Shandong, suggesting that IL-23R gene polymorphism (rs17375018 G) may play a critical role in susceptibility to HT.

Abstract
BACKGROUND Previous studies have indicated that single nucleotide polymorphisms (SNPs) of the interleukin-17 (IL-17) gene are associated with an increased risk of gastric cancer. However, the findings were inconsistent. MATERIALS AND METHODS To provide a more reliable estimation of the association between SNPs in the IL-17 gene and the susceptibility to gastric cancer, we searched PubMed, CNKI, and Wan Fang databases and selected finally six studies covering 2,366 cases and 3,205 controls to perform a meta-analysis. RESULTS Statistical analyses showed that an rs2275913 polymorphism within the IL-17A gene was significantly associated with an increased risk of gastric cancer using a generalized odds ratio (ORG, a model-free approach). Moreover, we also found that the 'A' allele carriers of IL-17A rs2275913 had a significant link with clinicopathological features. However, no significant positive signals were observed in the association analysis of the rs3748067 and rs763780 polymorphisms with the risk of gastric cancer in IL-17A and IL-17F, respectively. CONCLUSIONS Despite some limitations, the present meta-analysis provided a more precise estimation of the relationship between the IL-17 gene SNPs and gastric cancer risk compared with individual studies.

Abstract
Interleukin (IL-)23 is a central cytokine controlling TH17 development. Overshooting IL-23 signaling contribute to autoimmune diseases. Moreover, GWAS studies have identified several SNPs within the IL-23 receptor, which are associated with autoimmune diseases. IL-23 is a member of the IL-12-type cytokine family and consists of IL-23p19 and p40. Within the IL-12 family, IL-12 and IL-23 share the p40 cytokine subunit and the IL-12Rβ1 as one chain of the receptor complex. For signaling, IL-23 triggers heterodimerization of IL-12Rβ1 and the IL-23R. Subsequently, signal transduction pathways including JAK/STAT, MAPK and PI3K are activated. Most studies have investigated the biological relevance of IL-23 in the development of TH17 cells and autoimmunity, whereas less is known about the molecular context of IL-23 biology. Therefore, we focused on IL-23 receptor complex assembly, signal transduction and functional relevance of IL-23R SNPs in the context of IL-23-inhibitory principles.

Abstract
BACKGROUND Heredity and environmental exposures may contribute to a predisposition to allergic rhinitis (AR). Autoimmunity may also involve into this pathologic process. FCRL3 (Fc receptor-like 3 gene), a novel immunoregulatory gene, has recently been reported to play a role in autoimmune diseases. OBJECTIVE This study was performed to evaluate the potential association of FCRL3 polymorphisms with AR in a Chinese Han population. METHODS Five single-nucleotide polymorphisms of FCRL3, rs945635, rs3761959, rs7522061, rs10489678 and rs7528684 were genotyped in 540 AR patients and 600 healthy controls using a PCR-restriction fragment length polymorphism assay. Allele, genotype and haplotype frequencies were compared between patients and controls using the χ2 test. The online software platform SHEsis was used to analyze their haplotypes. RESULTS This study identified three strong risk SNPs rs7528684, rs10489678, rs7522061 and one weak risk SNP rs945635 of FCRL3 in Chinese Han AR patients. For rs7528684, a significantly increased prevalence of the AA genotype and A allele in AR patients was recorded. The frequency of the GG genotype and G allele of rs10489678 was markedly higher in AR patients than those in controls. For rs7522061, a higher frequency of the TT genotype, and a lower frequency of the CT genotype were found in AR patients. Concerning rs945635, a lower frequency of the CC genotype, and a higher frequency of G allele were observed in AR patients. According to the analysis of the three strong positive SNPs, the haplotype of AGT increased significantly in AR cases (AR = 38.8%, Controls = 24.3%, P = 8.29 × 10(-14), OR [95% CI] 1.978 [1.652~2.368]). CONCLUSIONS This study found a significant association between the SNPs in FCRL3 gene and AR in Chinese Han patients. The results suggest these gene polymorphisms might be the autoimmunity risk for AR.

Abstract
OBJECTIVES Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Interleukin-27 (IL-27), a novel IL-12 family member, has recently been reported to play a role in some immune-related disorders. This study was performed to evaluate the potential association of IL-27 polymorphisms with AR in a Chinese Han population. DESIGN AND METHODS A case-control study was performed in 445 Chinese AR patients and 691 healthy controls. Three SNPs in the IL-27p28 gene, including rs153109, rs17855750 and rs181206, were detected using a polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). RESULTS A significantly increased prevalence of the rs153109 TT genotype and the T allele was found in AR patients, while a decreased prevalence of the CT and CC genotypes and the C allele was found. For rs153109, the TT genotype and the T allele were significantly associated with the risk of AR, but the CT and CC genotypes and the C allele decreased the risk of AR; for rs17855750, the TT genotype and T allele were risk factors for AR, and the GT genotype and G allele provided protection. TTT and TTC haplotypes in the IL-27p28 gene were positively correlated with AR, while CGT, CTC and CTT haplotypes were associated with a significantly decreased risk of AR. CONCLUSION This study indicates that IL-27p28 polymorphisms rs153109 and rs17855750 are likely involved in AR susceptibility, making them potentially useful genetic biomarkers for AR susceptibility in the Chinese Han population.

Abstract
Several polymorphisms in interleukin-4 receptor α-chain (IL-4RA) have been implicated in susceptibility to allergic rhinitis (AR), but the results are inconclusive. This meta-analysis was aimed to clarify the impact of IL-4RA polymorphisms on AR risk. Pubmed, EMBASE and Cochrane Library were searched until 2 October 2013 for eligible studies on IL-4RA polymorphism. Data were extracted, and pooled odd ratios (ORs) as well as 95 % confidence intervals (95 % CIs) were calculated. Ten studies with 1,552 AR patients and 1,473 controls were included. The results indicated that IL4RA Gln551Arg polymorphism was associated with AR susceptibility in Asian (AG vs. AA OR = 1.63, 95 % CI 1.17-2.28, I (2) = 57 %; GG vs. AA, OR = 1.69, 95 % CI 1.00-2.86, I (2) = 7 %; AG + GG vs. AA, OR = 1.68, 95 % CI 1.18-2.39, I (2) = 64 %; GG vs. AG + AA, OR = 1.47, 95 % CI 0.87-2.49, I (2) = 0 %; G vs. A, OR = 1.54, 95 % CI 1.14-2.10, I (2) = 64 %) but not in Caucasian. IL4RA Ile50 Val as well as Ser478Pro polymorphisms were not associated with AR susceptibility both in Asian and in Caucasian. Gene-gene and gene-environment interactions should be investigated in the future.

Abstract
We aimed to explore the association between interleukin-17 (IL-17) polymorphisms, Helicobacter pylori infection, and subsites in gastric cancer risk in a Chinese population. We genotyped three promoter polymorphisms (rs2275913G>A, rs3748067C>T, and rs763780T>C) of IL-17 in a case-control study of 260 gastric cancer patients and 512 healthy controls. An unconditional multiple logistical regression model was used to calculate the effects of IL-17 gene polymorphisms on gastric cancer risk. The rs2275913 AA (adjusted OR = 1.69, 95 % CI = 1.15-2.49) and rs3748067 TT (adjusted OR = 1.73, 95 % CI = 1.03-2.94) genotypes were associated with an increased risk of gastric cancer. We observed a significant interaction among rs2275913G>A, rs3748067C>T, and H. pylori infection on the risk of gastric cancer (p for interaction of 0.036 and 0.048, respectively). H. pylori infection subjects carrying the rs2275913 AA (adjusted OR = 2.48, 95 % CI = 1.49-4.12) and rs3748067 TT (adjusted OR = 2.54, 95 % CI = 1.34-5.12) genotypes had a greatly increased risk of gastric cancer compared to negative H. pylori participants. Similarly, subjects carrying the rs2275913 AA (adjusted OR = 2.09, 95 % CI = 1.25-3.45) and rs3748067 TT (adjusted OR = 2.29, 95 % CI = 1.20-4.20) genotypes had a moderately increased risk of noncardia gastric cancer. A significant interaction was observed between the rs2275913G>A and rs3748067C>T genotype and subsites of gastric cancer (p for interaction of 0.044 and 0.008, respectively). The rs2275913G>A and rs763780T>C polymorphisms increase gastric cancer risk, and interact with H. pylori infection and subsites. These findings could be helpful in identifying individuals at increased risk for developing gastric cancer.
