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

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

This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy(SLIT) versus multi-allergen subcutaneous immunotherapy(SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6–13 years with allergic rhinitis(AR) induced by house dust mites(HDMs). The AR polysensitized children(n=78) were randomly divided into two groups: SLIT group and SCIT group. Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts(HDM in combination with other clinically relevant allergen extracts). Before and 1 year after the allergen-specific immunotherapy(ASIT), the total nasal symptom scores(TNSS), total medication scores(TMS) and IL-4 levels in peripheral blood mononuclear cells(PBMCs) were compared respectively between the two groups. The results showed that the TNSS were greatly improved, and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups(SLIT group: P<0.001; SCIT group: P<0.001). There were no significant differences in any outcome measures between the two groups(for TNSS: P>0.05; for TMS: P>0.05; for IL-4 levels: P>0.05). It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6–13-year-old children with HDM-induced AR.展开更多

Allergic rhinitis can influence patient's daily activity severely and may precede the development of asthma, especially if it is not diagnosed and treated correctly. In addition to subcutaneous immunotherapy, sublingual immunotherapy(SLIT) represents the only treatment being potentially able to cure allergic respiratory diseases, by modulating the immune system activity. This review clearly summarizes and analyzes the available randomized, double-blinded, placebo-controlled trials, which aimed at evaluating the effectiveness and the safety of grass pollen and house dust mite SLIT for the specific treatment of pediatric allergic rhinitis. Our analysis demonstrates the good evidence supporting the efficacy of SLIT for allergic rhinitis to grass pollens in children, whereas trials regarding pediatric allergic rhinitis to house dust mites present lower quality, although several studies supported its usefulness.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

Skin prick test was done on all patients. ASIT was initiated with common inhalant indoor allergens as per standard protocol and patients were assessed at the start and at 2 m, 6 m and 18 months of ASIT. ASIT was able to significantly reduce the symptom score in all the three groups namely sneezing, rhinorrhoea and nasal itching (p < 0.001). Concurrently it was also able to produce a significant reduction in the usage of concomitant drug intake (p < 0.001) thereby implying a decrease in morbidity. When assessed regarding clinical efficacy, ASIT was found to be satisfactory or highly effective in more than 75% patients. ASIT has got a role in clinical practice in polysensitized patients in field conditions. This is based on the evidence that besides decrease in hypersensitivity/symptoms, it also has an effect on minimizing the necessity of taking drugs to relieve the symptoms, which has strong implications of economics and toxicity, while treating patients.展开更多

The latest concept in allergic disease is the role of regulatory T cells (Treg). Interleukin-2 enhances the function and survival of Treg to perform its function as a controller of effector for forming a tolerant system by suppressing and regulating the homeostasis system. Treg has a transcription factor FoxP3 which plays a role in developing major function of Treg and progression to produce IL-10 and TGF-?. The atopic diseases are caused by a deficiency of Treg. The new perspective is low-dose IL-2 therapy towards autoimmune disease and allergic inflammation. Low-dose IL-2 therapy requires further clinical studies to optimize the dose, time, and the schedule of the IL-2 treatment. FoxP3 has the potential to assist in evaluating the active process of immunological process, which cannot be evaluated by Th1 and Th2 markers, and FoxP3 can be a successful immunotherapy marker.展开更多

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Objective:To explore the effect of"Yingxiang-Hegu"on Th1,Th2-related cytokines and[2]transcription factors T-bet and GATA-3 in rats with allergic rhinitis.Methods:Rats were randomly divided into three groups:blank group,model group and acupoint group.The rat model of ovalbumin(OVA)AR was established,and the general condition of the rats was observed and scored.Acupuncture intervention was performed on the acupoint group on the second day after successful modeling,once per day for 20 min for 10 d.After intervention,the general behavior,behavioral score and histomorphological changes of nasal mucosa were observed.Eosinophils(EOS)were counted under microscope after nasal lavage smear staining,and the contents of total IgE,IFN-γ,IL-12,IL-4 and IL-5 in serum were detected by ELISA.Westernblot and IHC were used to detect the protein level and positive protein expression of specific transcription factors T-bet and GATA-3 in rat nasal mucosa.Results:After the establishment of the model,except for the blank group,the behavioral observation scores of rats in the model group and acupoint group were more than 5 points,indicating that the model was successful.After acupuncture intervention on acupoint"Yingxiang-Hegu",the behavioral score of rats in the acupoint group and western medicine group was significantly lower than that in the model group(P<0.05).Microscopic examination showed that the structure of nasal mucosa in the model group was obviously damaged,cilia were arranged discontinuously,uneven,local congestion and swelling,a large number of epithelial cells exfoliated and necrotic,goblet cell proliferation,obvious inflammatory cell infiltration.The pathological degree of nasal mucosa in the pair point group was significantly less than that in the model group.Compared with the model group,the levels of IFN-γ,IL-2 and IL-12 in serum were significantly increased,while IgE,IL-4,IL-5 and IL-6 were significantly decreased,GATA-3 protein and positive expression in nasal mucosa were significantly decreased and T-bet was significantly increased after acupuncture.Conclusion:Acupuncture at"Yingxiang-Hegu"can effectively improve the nasal sensitive symptoms and control nasal inflammation in AR rats.The mechanism may be that acupuncture at Yingxiang-Hegu can up-regulate the expression of T-bet,decrease the level of GATA-3,promote the production of Th1 cytokines and inhibit the synthesis and secretion of Th2 cells,thus restoring the immune balance of Th1 and Th2.
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: 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It has always been controversial whether a single allergen performs better than multiple allergens in polysensitized patients during the allergen-specific immunotherapy. This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy(SLIT) versus multi-allergen subcutaneous immunotherapy(SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6–13 years with allergic rhinitis(AR) induced by house dust mites(HDMs). The AR polysensitized children(n=78) were randomly divided into two groups: SLIT group and SCIT group. Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts(HDM in combination with other clinically relevant allergen extracts). Before and 1 year after the allergen-specific immunotherapy(ASIT), the total nasal symptom scores(TNSS), total medication scores(TMS) and IL-4 levels in peripheral blood mononuclear cells(PBMCs) were compared respectively between the two groups. The results showed that the TNSS were greatly improved, and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups(SLIT group: P<0.001; SCIT group: P<0.001). There were no significant differences in any outcome measures between the two groups(for TNSS: P>0.05; for TMS: P>0.05; for IL-4 levels: P>0.05). It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6–13-year-old children with HDM-induced AR.
文摘Allergic rhinitis affect 10%-20% of pediatric population and it is caused by the Ig E-sensitization to environmental allergens, most importantly grass pollens and house dust mites. Allergic rhinitis can influence patient's daily activity severely and may precede the development of asthma, especially if it is not diagnosed and treated correctly. In addition to subcutaneous immunotherapy, sublingual immunotherapy(SLIT) represents the only treatment being potentially able to cure allergic respiratory diseases, by modulating the immune system activity. This review clearly summarizes and analyzes the available randomized, double-blinded, placebo-controlled trials, which aimed at evaluating the effectiveness and the safety of grass pollen and house dust mite SLIT for the specific treatment of pediatric allergic rhinitis. Our analysis demonstrates the good evidence supporting the efficacy of SLIT for allergic rhinitis to grass pollens in children, whereas trials regarding pediatric allergic rhinitis to house dust mites present lower quality, although several studies supported its usefulness.
文摘Objective:To discuss the effect of lesser-known potential risk factors,such as bedroom showers,on the prevalence of allergic rhinitis.Methods:A cross-sectional,population-based study was performed using both survey and fungal culturing in southern Taiwan.There were 998 participants enrolled in the survey,and 513 sets of fungal culture obtained.With score for allergic rhinitis(SFAR) more than 7,the patient was defined to have allergic rhinitis.Risks of allergic rhinitis were calculated as odds ratios for various predicted risk factors by logistic regression.Correlation between predicted risk factors and fungal level were examined with linear regression.Results:The adjusted odds ratio of frequently using bedroom shower to having allergic rhinitis was 1.572(95% confidence interval:1.090-2.265),and 0.962 for people with older age to have AR(95% confidence interval:0.949-0.976).As to the 24-hour fungal level,the standardized coefficient was 0.254 for frequent use of bedroom shower,and 0.106 for window open hours.Conclusions:Use of bedroom shower is a potential risk factor for allergic rhinitis development.

文摘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.
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Though efficacy of Allergen Specific Immunotherapy (ASIT) has been proved in many studies, reports about success in clinical practice and under field conditions in alleviating the suffering or decreasing the morbidity in patients of Allergic Rhinitis are few. 260 patients of Allergic Rhinitis without coexisting diseases were included. Skin prick test was done on all patients. ASIT was initiated with common inhalant indoor allergens as per standard protocol and patients were assessed at the start and at 2 m, 6 m and 18 months of ASIT. ASIT was able to significantly reduce the symptom score in all the three groups namely sneezing, rhinorrhoea and nasal itching (p < 0.001). Concurrently it was also able to produce a significant reduction in the usage of concomitant drug intake (p < 0.001) thereby implying a decrease in morbidity. When assessed regarding clinical efficacy, ASIT was found to be satisfactory or highly effective in more than 75% patients. ASIT has got a role in clinical practice in polysensitized patients in field conditions. This is based on the evidence that besides decrease in hypersensitivity/symptoms, it also has an effect on minimizing the necessity of taking drugs to relieve the symptoms, which has strong implications of economics and toxicity, while treating patients.

文摘Objective:Ephedra asarum aconite decoction is used in the clinical treatment of allergic rhinitis.We investigated the effects of ephedra asarum aconite decoction on Th1/Th2 balance in two animal models of allergic rhinitis and in activated T cells in vitro.Methods:Animal models of simple and compound kidney yang deficiency types of allergic rhinitis were treated with ephedra asarum aconite decoction to observe the efficacy of this traditional Chinese medicine formula on allergic symptoms,serum cytokines,and tissue RNA levels.We also cultured and activated T cells from the mouse.After treatment with ephedra asarum aconite decoction,we tested the proliferation and differentiation of T cells.Results:Ephedra asarum aconite decoction relieved allergy symptoms in both types of animal models,and was more effective in the compound kidney yang deficiency model In addition to its anti-allergic efficacy,ephedra asarum aconite decoction significantly improved the health status of animals in the compound kidney yang deficiency groups,significantly made their bodyweight rising up,and significantly increased the T-bet mRNA/GATA-3 mRNA ratio.Moreover,ephedra asarum aconite decoction promoted the proliferation of activated T cells and inhibited the differentiation to Th2 cells in vitro.Conclusions:Ephedra asarum aconite decoction regulates the balance of Th1/Th2 to ameliorate allergic conditions.
文摘Allergic rhinitis (AR) is the inflammation of nasal mucosa due to the type 1 hypersensitivity reactions mediated by immunoglobulin E (IgE) and triggered by certain allergens. The latest concept in allergic disease is the role of regulatory T cells (Treg). Interleukin-2 enhances the function and survival of Treg to perform its function as a controller of effector for forming a tolerant system by suppressing and regulating the homeostasis system. Treg has a transcription factor FoxP3 which plays a role in developing major function of Treg and progression to produce IL-10 and TGF-?. The atopic diseases are caused by a deficiency of Treg. The new perspective is low-dose IL-2 therapy towards autoimmune disease and allergic inflammation. Low-dose IL-2 therapy requires further clinical studies to optimize the dose, time, and the schedule of the IL-2 treatment. FoxP3 has the potential to assist in evaluating the active process of immunological process, which cannot be evaluated by Th1 and Th2 markers, and FoxP3 can be a successful immunotherapy marker.
