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 χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 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.展开更多

It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.展开更多

Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.展开更多

Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.展开更多

Over the past few years nasal cytology has been rarely used in pediatrics, nevertheless its clinical and scientific applications seem to be very promising. The advantages of this technique are different: the ease of performance, the noninvasiveness allowing repetition and the low cost. We evaluated 100 children, from 2 to 15 years old, referred to our outpatient service for allergic children for suspected allergic rhinitis (AR). After skin prick test (SPT) or Radio Allergo Sorbent Test (RAST), 59/100 subjects were classified as affected by AR, while 8 children refused to be tested. According to ARIA guidelines, the 59 children with AR (4 - 15 years old) were divided in 56 with persistent AR and 3 with an intermittent form. Nine out of 59 children with AR had a significant number of neutrophils and eosinophils at the nasal cytology, documenting the presence of “minimal persistent inflammation”. Eleven out of 59 AR patients showed a positive swab for bacteria. Children with nonallergic rhinitis (NAR) were 33/100 (2 - 15 years old). After nasal cytology, 17/33 children were classified as NARES (nonallergic rhinitis with eosinophils), including one X-linked agammaglobulinemia (XLA) child, 1/33 as NARESMA (nonallergic rhinitis with eosinophils and mast cell) and another 1/33 as NARMA (nonallergic rhinitis with mast cell). In conclusion, nasal cytology allowed us to correctly classify children with NAR and to better assess the condition of children with AR.展开更多

[Methods]48 patients with AR were hospitalized and randomly assigned to raw-radish treatment group( 36 patients) or placebo group( 12 patients). Every patient took about 150 g raw radish( experimental group) or cooked radish( placebo group) one time or separately a day. [Results]By continuously taking raw radish for fifteen days,the total cure rate reached 80. 6% and total valid rate reached 94. 4%,with the valid rate 100% for persistent AR and 66. 7% for intermittent AR. But cooked radish( placebo) was invalid to AR. Presumably the wonder efficacy of raw radish may be related with isothiocyanates in radish. Since isothiocyanates are susceptible to hydrolysis by cooking,so radish must be eaten raw. [Conclusions] Raw radish therapy works wonders for AR,which may be more effective,safer,cheaper and simpler method for prevention and treatment of AR at present.展开更多

Eighteen BALB/c mice were divided into three groups; the ovalbumin （OVA）-sen- sitized/challenged group, which received saline orally for 6 weeks （OVA group）, the OVA-sensitized/challenged group, which received LFK orally for 6 weeks （LFK-fed group）, and the non-sensitized group, which received saline for 6 weeks （saline control group）. Nasal rubbing and sneezing were monitored during the study. After the final challenge, interleukin （IL）-4, interferon （IFN）-y, and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined, eosinophilic infiltrate into the upper airway was quantified, and splenic CD4~CD25＋ regulatory T cells （Tregs） were examined by flow cytometry. We found that nasal rubbing was sig- nificantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35, and sneezing was significantly inhibited by LFK administration for 35 d. LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group. There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4, IFN-y, and OVA-specific IgE. Interestingly, the LFK-fed mice had a significantly greater percentage of splenic CD4＋CD25＋ Tregs than OVA group.

文摘Allergic rhinitis（AR）,with an increasing uptrend of the prevalence in many developed and developing countries,is a global health problem that affects people of all ages and ethnic groups.However,data on the prevalence of self-reported AR in western China are rare.This study investigated the epidemiological features of self-reported AR in western China.In the cross-sectional,population-based study,a validated questionnaire survey on self-reported AR was carried out in 4 major cities in western China by multistage,stratified and cluster sampling,from January to December 2008.The total prevalence rate was 34.3%,with 32.3%（Chongqing）,34.3%（Chengdu）,37.9%（Urumqi）,30.3%（Nanning）,respectively.The prevalence presented to increase with age before 30 years old while decrease with age after 30 years old,and the highest prevalence was in 19-30 years group in Chongqing,Chengdu and Nanning which significantly showed ＂persistent and moderate-severe＂ type（P0.0001）;In Urumqi,there wasn＇t a significant increasing or decreasing trend of prevalence rate with age but with an ＂intermittent and mild＂predominance（P0.0001）.There were no distinct sexual differences in prevalence rates in the 4 cities.The morbidity was positively related to monthly average temperature and sunshine（r=0.76645,P=0.0036;r=0.67303,P=0.0165）,but negatively associated with relative humidity（r=-0.64391,P=0.0238） in Urumqi.Interestingly,the monthly morbidity was negatively associate with average temperature,sunshine and precipitation in Nanning（r=-0.81997,P=0.0011;r=-0.60787,P=0.0360;r=-0.59443,P=0.0415）.Self-reported AR is becoming common in western China with a rapid development in recent years,affecting about three persons out of ten.The climatic factors may have an indirect impact on the prevalence rate through the effects on the local allergens.
文摘Objective:To evaluate the effect of myricetin on ovalbumin(OVA)-induced allergic rhinitis in mice.Methods:Mice were sensitized and challenged using OVA(5%,500 mL)intraperitoneally and intranasally,respectively,on an alternative day for 14 days,followed by administration of myricetin(50,100,and 200 mg/kg)till day 21.Nasal symptoms,biochemical parameters,protein expressions,and histopathology were observed.Results:OVA-induced increased nasal symptoms including rubbing,sneezing,and discharge were significantly reduced by myricetin(100and 200 mg/kg)(P<0.05).Myricetin also protected against histamine challenge and attenuated elevated serum immunoglobulin E(IgE;total and OVA-specific),total IgG1,andβ-hexosaminidase levels,as well as leukotriene C4 and interleukins levels in nasal lavage fluid(P<0.05).Western blot analysis showed that myricetin significantly upregulated the protein expression of T-box expressed in T cells,while downregulating the protein expression of GATA binding protein 3,NF-κB,and IκB-α(P<0.05).Additionally,OVA-induced histopathological abberations in the nasal mucosa was markedly ameliorated by myricetin treatment(P<0.05).Conclusions:Myricetin exerts anti-allergic effects against OVAinduced allergic rhinitis via regulating Th1/Th2 balance.
文摘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 χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 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.

文摘According to the proportion of 1:1, konjac flour and mulberry leaf powder are compounded into a kind of dietary fiber source(KMCP). It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.
文摘Background: Allergic rhinitis is a common and high incidence disease in clinic, which has a certain impact on the work, life and social activities of patients. Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.
文摘BACKGROUND There are many adverse reactions in the treatment of allergic rhinitis(AR)mainly with conventional drugs.Leukotriene receptor antagonists,glucocorticoids and nasal antihistamines can all be used as first-line drugs for AR,but the clinical effects of the three drugs are not clear.AIM To examine the impact of glucocorticoids,antihistamines,and leukotriene receptor antagonists on individuals diagnosed with AR,specifically focusing on their influence on serum inflammatory indexes.METHODS The present retrospective study focused on the clinical data of 80 patients diagnosed and treated for AR at our hospital between May 2019 and May 2021.The participants were categorized into the control group and the observation group.The control group received leukotriene receptor antagonists,while the observation group was administered glucocorticoids and antihistamines.Conducted an observation and comparison of the symptoms,physical sign scores,adverse reactions,and effects on serum inflammatory indexes in two distinct groups of patients,both before and after treatment.RESULTS Subsequent to treatment,the nasal itching score,sneeze score,runny nose score,nasal congestion score,and physical signs score exhibited notable discrepancies(P<0.05),with the observation group demonstrating superior outcomes compared to the control group(P<0.05).The interleukin(IL)-6,IL-10,tumor necrosis factor-alpha,Soluble Intercellular Adhesion Molecule-1,Leukotriene D4 after treatment were significantly different and the observation group It is better than the control group,which is statistically significant(P<0.05).Following the intervention,the incidence of adverse reactions in the observation group,including symptoms such as nasal dryness,discomfort in the throat,bitter taste in the mouth,and minor erosion of the nasal mucosa,was found to be 7.5%.This rate was significantly lower compared to the control group,which reported an incidence of 27.5%.The difference between the two groups was statistically significant(P<0.05).CONCLUSION Glucocorticoids and antihistamines have obvious therapeutic effects,reduce serum inflammatory index levels,relieve symptoms and signs of patients,and promote patients'recovery,which can provide a reference for clinical treatment of AR.

文摘Objective:To study the key target genes and signaling pathways in the treatment of Allergic Rhinitis(AR)with Radix Aconiti Lateralis Preparata(aka Fuzi).Methods:The TCMPS and PubChem databases were used to screen the active ingredients and target genes of Fuzi using oral bioavailability and drug similarity as screening conditions,and the GeneCards database was used to screen the target genes of AR.The online tool Venny2.1 was used to screen the target genes of Fuzi for the treatment of Allergic Rhinitis;the STRING database was used to obtain the protein-protein interaction(PPI)network of drug-disease targets,and the key target genes were identified by the MCC algorithm.The potential biological processes and signaling pathways were identified by GO enrichment and KEGG enrichment analysis.Finally,animal experiments were conducted to demonstrate the therapeutic effect ofFuzi on Allergic Rhinitis.Results:The TCMSP,PubChem and GeneCards databases were used to screen the 21 active compound components of Fuzi and 68 potential therapeutic target genes of Fuzi for Allergic Rhinitis.PPI network analysis identified the top ten key target genes,namely:PTGS2,TNF,IL6,AKT1,ALB,STAT3,CCL2,CXCL8,VEGFA and JUN,GO functional and KEGG pathway enrichment analysis showed that the significantly enriched functions and pathways of Fuzi on Allergic Rhinitis were closely related to Allergic Rhinitis.Finally,animal experiments were conducted to verify that Fuzi is effective in the treatment of Allergic rhinitis.Conclusion:Increased expression of IL-6 and TNF-αin nasal mucosal tissues of patients with Allergic Rhinitis was positively correlated with indicators related to the disease activity of AllergicRhinitis.Fuzi ameliorated the inflammatory changes in mice with Allergic Rhinitis by inhibiting the activation of Toll-like signaling pathway in the nasal mucosa and decreasing the expression activity of IL-6 and TNF-α.
文摘Chronic rhinitis is a very common disease, as the prevalence in the general population resulted to be 40%. Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.
文摘Nasal cytology is a diagnostic tool currently used in rhinology to study either allergic and vasomotor rhinological disorders or infectious and inflammatory rhinitis. Over the past few years nasal cytology has been rarely used in pediatrics, nevertheless its clinical and scientific applications seem to be very promising. The advantages of this technique are different: the ease of performance, the noninvasiveness allowing repetition and the low cost. We evaluated 100 children, from 2 to 15 years old, referred to our outpatient service for allergic children for suspected allergic rhinitis (AR). After skin prick test (SPT) or Radio Allergo Sorbent Test (RAST), 59/100 subjects were classified as affected by AR, while 8 children refused to be tested. According to ARIA guidelines, the 59 children with AR (4 - 15 years old) were divided in 56 with persistent AR and 3 with an intermittent form. Nine out of 59 children with AR had a significant number of neutrophils and eosinophils at the nasal cytology, documenting the presence of “minimal persistent inflammation”. Eleven out of 59 AR patients showed a positive swab for bacteria. Children with nonallergic rhinitis (NAR) were 33/100 (2 - 15 years old). After nasal cytology, 17/33 children were classified as NARES (nonallergic rhinitis with eosinophils), including one X-linked agammaglobulinemia (XLA) child, 1/33 as NARESMA (nonallergic rhinitis with eosinophils and mast cell) and another 1/33 as NARMA (nonallergic rhinitis with mast cell). In conclusion, nasal cytology allowed us to correctly classify children with NAR and to better assess the condition of children with AR.

文摘[Objectives] To explore a kind of simple and effective dietotherapy for allergic rhinitis( AR). [Methods]48 patients with AR were hospitalized and randomly assigned to raw-radish treatment group( 36 patients) or placebo group( 12 patients). Every patient took about 150 g raw radish( experimental group) or cooked radish( placebo group) one time or separately a day. [Results]By continuously taking raw radish for fifteen days,the total cure rate reached 80. 6% and total valid rate reached 94. 4%,with the valid rate 100% for persistent AR and 66. 7% for intermittent AR. But cooked radish( placebo) was invalid to AR. Presumably the wonder efficacy of raw radish may be related with isothiocyanates in radish. Since isothiocyanates are susceptible to hydrolysis by cooking,so radish must be eaten raw. [Conclusions] Raw radish therapy works wonders for AR,which may be more effective,safer,cheaper and simpler method for prevention and treatment of AR at present.

文摘In the current study, we sought to investigate whether lysed Enterococcus faecalis FK-23 （LFK）, a heat-killed probiotic preparation, attenuated eosinophil influx into the upper airway and had immunomodulatory activity in a murine allergic rhinitis model. Eighteen BALB/c mice were divided into three groups; the ovalbumin （OVA）-sen- sitized/challenged group, which received saline orally for 6 weeks （OVA group）, the OVA-sensitized/challenged group, which received LFK orally for 6 weeks （LFK-fed group）, and the non-sensitized group, which received saline for 6 weeks （saline control group）. Nasal rubbing and sneezing were monitored during the study. After the final challenge, interleukin （IL）-4, interferon （IFN）-y, and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined, eosinophilic infiltrate into the upper airway was quantified, and splenic CD4~CD25＋ regulatory T cells （Tregs） were examined by flow cytometry. We found that nasal rubbing was sig- nificantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35, and sneezing was significantly inhibited by LFK administration for 35 d. LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group. There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4, IFN-y, and OVA-specific IgE. Interestingly, the LFK-fed mice had a significantly greater percentage of splenic CD4＋CD25＋ Tregs than OVA group. Our results indicate that oral administration of LFK may alleviate nasal symptoms, reduce nasal eosinophilia, and increase the percentage of CD4＋CD25＋ Tregs in experimental allergic rhinitis.
