Progress in the Application of Mendelian Randomization Analysis in Allergic Rhinitis

Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mediated mainly by immunoglobulin E (IgE) in atopic individuals after exposure to allergens, with the typical symptoms of paroxysmal sneezing, watery runny nose, itchy nose and nasal congestion. Mendelian randomization (MR), an innovative epidemiological approach that uses common genetic variants as instrumental variables for exposure, thus enabling prediction of their causal relationship with outcomes, has been widely used in recent years in studies related to AR. This paper provides a review of the method and its progress in the field of allergic rhinitis research.

Establishment and Evaluation of a Mouse Model of Allergic Rhinitis

[Objectives]To explore a new method for induction of allergic rhinitis in mice,and compare and evaluate it with common modeling methods.[Methods]36 mice were randomly divided into the control group,blank group and experimental group,and there were 12 mice in each group.The mice in the control group were conventionally induced.That is,the mice were first injected intraperitoneally with the mixture composed of OVA 50μg,[Al(OH)3]5 mg and 1ml of normal saline once every other day,and then since the 15 th d,20μL of 5%OVA solution was dropped into each nasal cavity once a day,which lasted for 7 d.The blank group was treated with the same amount of normal saline according to the control group,and received intraperitoneal injection and bilateral nasal drip respectively.In the experimental group,mice were first given intraperitoneal injection of the mixture composed of ovalbumin(OVA)75μg,aluminum hydroxide gel[Al(OH)3]8 mg and normal saline 1.5 mL for basic sensitization.On the 26 th d,20μL of 3%OVA solution was dropped into each nasal cavity once a day,which lasted for 10 d.The number of sneezes,the number of nose scratching,the amount of nasal discharge,and the activity of mice in each group were observed,and the behavior of allergic reaction was scored.Meanwhile,the number of eosinophils in the nasal discharge of mice and the IgE content in serum were measured.[Results]The score of nasal stimulation symptoms,the number of eosinophils and serum IgE level of mice in the control group and the experimental group were higher than those in the blank group(P<0.05),and there was no statistical significance between the two groups in the three indicators(P>0.05).[Conclusions]The modeling method was more suitable for the development of allergic rhinitis patients condition,and reduced the probability of death of mice due to modeling,and simplified the experimental operation.

Effect of Centipeda Herba Volatile Oil on Allergic Rhinitis by Nasal Sniffing

[Objectives] To explore the efficacy of different concentrations of Centipeda Herba volatile oil in the treatment of allergic rhinitis (AR) by nasal sniffing and the optimal drug concentration.[Methods] Forty-eight mice were randomly divided into control group, blank group, alcohol treatment group, low concentration group, medium concentration group and high concentration group, with 8 mice in each group. Except for the blank group, each mouse in the other groups was intraperitoneally injected with 1 mL of a mixture of 50 μgOVA+5 mg [Al(OH)_(3)] +1 mL of normal saline for 14 d. The allergic rhinitis mouse model was successfully established by intranasal instillation of 5% OVA solution on both sides (20 μL per side, once a day) from the 15 th day after stimulation for 7 d. The blank group was treated with the same amount of saline as above. The volatile oil of Centipeda Herba was obtained by steam distillation and petroleum ether extraction, and then was made into 1.25%, 2.5% and 5% volatile oil of Centipeda Herba with 75% alcohol. The control group was stimulated once every other day with reagent 2 after 7 d of stimulation (maintenance) until the end of treatment. The blank group was treated with 5 mL saline by nasal sniffing for 30 d, twice in the morning and evening, 30 min each time. The alcohol treatment group was treated with 5 mL of 75% alcohol, and the low concentration group, the medium concentration group and the high concentration group were treated with 5 mL of 1.25%, 2.5% and 5% Centipeda Herba volatile oil, respectively. The treatment time was the same as that of the blank group, and the treatment process was carried out in their respective closed contamination boxes. Before and after the treatment, the frequency of sneezing, the frequency of scratching nose, the amount of nasal discharge, activity and other general characteristics of the mice were observed, and the allergic behavior score was carried out. Besides, the IgE content in the serum of the mice was determined, and the eosinophils in the nasal discharge were counted.[Results] The scores of mice before and after treatment showed that there was no significant difference in the alcohol treatment group before and after treatment ( P >0.05), and there was significant difference in the low, medium and high concentration groups before and after treatment ( P <0.05), except that there was no significant difference between the control group and the alcohol treatment group ( P >0.05), and there was significant difference among the other groups ( P <0.05). The levels of IgE and the number of eosinophils in peripheral serum of mice in the control group, alcohol treatment group, low concentration group, medium concentration group and high concentration group were higher than those in the blank group ( P <0.05), and there was no significant difference between the two groups ( P >0.05).[Conclusions] Volatile oil of Centipeda Herba can be used to treat allergic rhinitis by nasal sniffing, and 5% volatile oil of Centipeda Herba has the best effect. During the treatment, sneezing and runny nose in mice were reduced. The results showed that nasal sniffing was less irritating to the nasal cavity and not easy to produce discomfort, the utilization rate of drugs was higher than that of traditional therapy, and the volatile oil could be preserved longer than that of traditional Chinese medicine.

Different medications for seasonal allergic rhinitis in adults:A systematic review and meta-analysis

BACKGROUND While the efficacy of medications such as fluticasone furoate(FF),fluticasone propionate(FP),and azelastine-fluticasone(AF)has been substantiated in comparison to their respective placebo controls,uncertainties persist regarding the comparative effectiveness of different intranasal agents.AIM To evaluate the efficacy of FP,FF,and AF in the treatment of adult patients with seasonal allergic rhinitis(SAR)using a meta-analytic approach.METHODS A computer search was conducted in Cochrane Library,PubMed,and EMBASE databases to identify randomized controlled trials assessing the effectiveness and safety of FF,FP,and AF in treating SAR.Data on treatment safety and efficacy were extracted and analyzed through meta-analysis.RESULTS A total of 20 studies were included,comprising 10590 participants.The results of the direct meta-analysis indicated that,compared to placebo,both relative Total Nasal Symptom Score(rTNSS)and relative Total Ocular Symptom Score(rTOSS)significantly decreased post-intervention[mean difference(MD)=-1.48,95%confidence interval(CI):-1.73 to-1.22;MD=-0.66,95%CI:-0.82 to-0.49],with similar findings observed across the FF,FP,and AF subgroups.The network meta-analysis results showed that for improving rTNSS and rTOSS,the SUCRA values ranking from highest to lowest were AF,FP,FF,and placebo.Improvements in rTNSS and rTOSS with FP,FF,and AF were all significantly greater than those observed with placebo,with AF demonstrating superior efficacy compared to both FP and FF.No statistically significant difference in rTNSS improvement was found between FP and FF,although FP exhibited significantly greater improvement in rTOSS compared to FF.CONCLUSION In adult patients with SAR,the combination of azelastine and fluticasone shows a significant effect in improving nasal and ocular symptoms,with FP demonstrating marked improvement in ocular symptoms compared to FF.

Mediation Effects of Placental Inflammatory Transcriptional Biomarkers on the Sex-Dependent Associations between Maternal Phthalate Exposure and Infant Allergic Rhinitis: A Population-Based Cohort Study

Objective Prenatal phthalate exposure has been associated with placental inflammatory factors and infant allergic rhinitis(AR).However,the results are inconclusive.We designed a population-based cohort study to examine the effects of placental inflammatory biomarkers on the sex-dependent associations between maternal phthalate exposure and infant AR.Methods A total of 2,348 pregnant women from Ma’anshan,Anhui Province,China,who were screened before antenatal visits and met the inclusion criteria,were included in the present study.We assessed AR in their offspring aged 36 months with a questionnaire.Quantitative PCR was performed to measure placental inflammatory factor m RNAs.The independent samples t-test and multivariable logistic regression were used to determine the associations between infant AR and maternal phthalates.Results Childhood AR may be related to education and family monthly income(P = 0.01).The phthalate metabolites,mono(2-ethylhexyl) phthalate(MEHP),mono(2-ethyl-5-hydroxyl) phthalate(MEHHP),in pregnant women were associated with a significantly increased risk for infant AR in males[P < 0.05;odds ratio(OR):1.285;95% confidence interval(CI):1.037-1.591,and OR:1.232,95% CI:1.008-1.507,respectively],but not females.Additionally,irritably-increased expression levels of HO-1 and IL-4 were associated with AR in male infants(OR:1.175;95% CI:1.038-1.329 and OR:1.181;95% CI:1.056-1.322,respectively).The association between maternal urinary MEHHP and placental HO-1 was marginally significant according to mediation analysis.Conclusion The associations of maternal MEHHP and MEOHP levels with fetal AR in males were significant.Placental HO-1 was a fractional mediator in the associations between MEHHP and AR.Thus,the placenta should be further investigated as a potential mediator of maternal exposure-induced disease risk in children.

Comparison of Allergic Rhinitis and Bronchial Asthma Impacts on Tympanometric Parameters in Children at Kano, Nigeria

Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction that affects sino-nasal mucosa and is characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness and eyes itching. Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ2 = 14.62, df = 4, p value = 0.01, Type B χ2 = 14.06, df = 4, p value = 0.01, Type C χ2 = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.

Ethno-medicinal study of Artemisia ordosica Krasch.(traditional Chinese/Mongolian medicine) extracts for treatment of allergic rhinitis and nasosinusitis

OBJECTIVE To evaluate the in vivo anti-inflammatory and allergic rhinitis(AR)alleviating effect as well as in vitro antimicrobial activities of Artemisia ordosica Krasch.(AOK)extracts to verify its ethno-medicinal claims.METHODS Crude extracts(methanol/95%-ethanol/ethyl acetate)of AOK root/stem/leaf and fractions(petroleum ether/ethyl acetate/n-butanol/aqueous)of AOK root extractwere prepared.Xylene-induced ear swelling model in mouse and ovalbumin(OVA)-induced AR model in guinea pig were established.Ear swelling degrees of mice were measured.The numbers of rubbing movement and sneezes of guinea pigs were counted to evaluate the symptoms of AR.The serum levels of histamine,INF-γ,IL-2/4/10,and VCAM-1 were measured by ELISA assay.The histological changes of nasal mucosa were investigated by light microscope after H&E staining.Antimicrobial activities of AOK extracts were also tested.LC-MS/MS analysis was performed to characterize the constituents of active extract and molecular docking was conducted to predict the biological mechanism.RESULTS In ear-swelling model,extract(100.00 mg·kg^-1)from the ethyl acetate layer of 95%ethanol(100.00 mg·kg^-1)showed better swelling inhibition in mice than positive control(dexamethasone,191.91 mg·kg^-1).In AR model,extract from the ethyl acetate layer of 95%ethanol significantly alleviated the AR symp⁃toms in guinea pigs,decreased the serum levels of histamine,INF-γ,IL-2/4/10,and VCAM-1,and reduced the infiltration of eosinophil in nasal mucosa.For Staphylococcus aureus,the ethyl acetate extract of AOK stem showed the highest inhibi⁃tion(MIC=1.25 g·L^-1),for Escherichia coli,n-butanol layer of 95%ethanol extract of AOK root showed the highest inhibi⁃tion(MIC=15.00 g·L^-1),for Candida glabrata,95%-ethanol extract of AOK stem showed the best inhibition(MIC=0.064 g·L^-1),while ethyl acetate and n-butanol layers showed similar inhibition on MRSA(MIC=7.50 g·L-1).LC-MS/MS characteriza⁃tion showed that dicaffeoylquinic acids account for more than 30%of ethyl acetate layer of AOK extract.Dicaffeoylquinic acids bind with histamine-1 receptor with high affinities and interesting modes.CONCLUSION Extracts from AOK had interesting anti-inflammatory activity in mice,alleviating effect against OVA-induced AR in guinea pigs,and antimicrobial activities in vitro,which support the ethno-medicinal use of it.The main constituents in ethyl acetate layer of AOK root extract are dicaffeoylquinic acids and could bind with histamine-1 receptor well.These findings highlighted the impor⁃tance of natural product chemistry study of AOK.

Near-Road Exposure to Air Pollution and Allergic Rhinitis: A Cross-Sectional Study among Vendors in Dakar, Senegal

Introduction: The work environment is one of the main causes of allergic rhinitis. The majority of vendors in Dakar work in places close to roads that are very frequented by vehicles, exposing them to increased air pollution. The study determined the prevalence of allergic rhinitis and its associated risk factors in these vendors. Methods: This was a cross-sectional survey based on a structured questionnaire, conducted among vendors in the neighborhoods of HLM, Medina and Petersen in Dakar, Senegal. A total of 200 vendors were interviewed. Symptoms of allergic rhinitis were defined as the simultaneous presence of rhinorrhea, nasal congestion and sneezing in the absence of respiratory infection. A logistic regression analysis was performed to determine the relationship between socio-demographic characteristics, occupational factors, and allergic rhinitis. Results: Results of the study show a prevalence of 43% of allergic rhinitis among vendors. Multivariate analysis showed that the independent factors associated with allergic rhinitis in these vendors were age [OR: 3.28 (1.02 - 10.51)], working area [OR: 8.31 (2.39 - 28.95)], exposure to multiple sources of pollution [OR: 4.08 (1.43 - 11.63)], and recurrent cold [OR: 4.39 (1.15 - 16.85)]. Conclusion: The prevalence of allergic rhinitis was high among vendors in Dakar. Our data suggest that exposure to air pollution at the workplace in vendors could lead to allergic rhinitis.

CX3CR1 receptor as a potential therapeutic target in chronic rhinosinusitis and allergic rhinitis

Chronic rhinosinusitis and allergic rhinitis are chronic inflammatory diseases that affect the mucous membrane of the nose and paranasal sinuses. These diseases are characterized by recruitment of inflammatory cells to the upper airway. For this to take place a complex interaction between inflammatory cells and the cytokines/chemokines(ligand) liberated at the site of inflammation is involved in a process termed chemotaxis or directed cell migration against concentration gradient of the ligand. This entails signal transduction through the cell surface receptor resulting in cellular functional response and directed migration. In this editorial the novel role of CX3CR1 receptor in the immunopathology of chronic inflammation of the nose and paranasal sinuses will be explored with its potential role as therapeutic target in chronic nasal inflammation.
