目的分析支气管扩张合并支气管哮喘患者的病原菌及危险因素。方法选取湖州市中心医院115例支气管扩张合并支气管哮喘患者作为观察组,另选取同期110例健康体检者作为对照组。分析患者病原菌的组成、耐药性及发病危险因素。结果观察组患者送检痰样本经痰培养,阳性检出者68例,阳性率为59.13%(68/115)。全部样本共分离出104株病原菌,其中革兰阴性菌92株(以铜绿假单胞菌最多,占54.81%),革兰阳性菌8株,真菌4株。药敏试验结果表明革兰阴性菌对复方新诺明、头孢曲松、左旋左氧氟沙星和阿莫西林/克拉维酸等药物的耐药性均较高,对妥布霉素、亚胺培南、头孢哌酮/舒巴坦和哌拉西林的耐药性较低。Logistic回归分析显示,吸烟史、药物过敏史、食物过敏史、过敏性鼻炎、哮喘、过敏性肺炎、慢性支气管炎及慢性阻塞性肺疾病均是支气管扩张伴支气管哮喘发生的危险因素。结论支气管扩张合并支气管哮喘患者其病原菌以革兰阴性菌为主,吸烟史、药物过敏史、食物过敏史、过敏性鼻炎等是支气管扩张伴支气管哮喘发生的危险因素。

Level of Fatty Acid Binding Protein 5 (FABP5) Is Increased in Sputum of Allergic Asthmatics and Links to Airway Remodeling and Inflammation

BackgroundThe inflammatory processes in the upper and lower airways in allergic rhinitis and asthma are similar. Induced sputum and nasal lavage fluid provide a non-invasive way to examine proteins involved in airway inflammation in these conditions.ObjectivesWe conducted proteomic analyses of sputum and nasal lavage fluid samples to reveal differences in protein abundances and compositions between the asthma and rhinitis patients and to investigate potential underlying mechanisms.MethodsInduced sputum and nasal lavage fluid samples were collected from 172 subjects with 1) allergic rhinitis, 2) asthma combined with allergic rhinitis, 3) nonallergic rhinitis and 4) healthy controls. Proteome changes in 21 sputum samples were analysed with two-dimensional difference gel electrophoresis (2D-DIGE), and the found differentially regulated proteins identified with mass spectrometry. Immunological validation of identified proteins in the sputum and nasal lavage fluid samples was performed with Western blot and ELISA.ResultsAltogether 31 different proteins were identified in the sputum proteome analysis, most of these were found also in the nasal lavage fluid. Fatty acid binding protein 5 (FABP5) was up-regulated in the sputum of asthmatics. Immunological validation in the whole study population confirmed the higher abundance levels of FABP5 in asthmatic subjects in both the sputum and nasal lavage fluid samples. In addition, the vascular endothelial growth factor (VEGF) level was increased in the nasal lavage fluid of asthmatics and there were positive correlations between FABP5 and VEGF levels (r=0.660, p<0.001) and concentrations of FABP5 and cysteinyl leukotriene (CysLT) (r=0.535, p<0.001) in the nasal lavage fluid.ConclusionsFABP5 may contribute to the airway remodeling and inflammation in asthma by fine-tuning the levels of CysLTs, which induce VEGF production.

Exhaled nitric oxide and nasal tryptase are associated with wheeze,rhinitis and nasal allergy in primary school children

Abstract

Rhinitis and asthma are the most common respiratory diseases in children. We assessed whether airway inflammation markers were associated with nasal allergies and self-reported symptoms of wheeze and rhinitis in 130 children 6–12 year old in an epidemiological context. Independent of sex and age, the fraction of exhaled nitric oxide (FeNO) and nasal mast cell (MC) activation (tryptase ≥?5?ng/mL) were positively associated with wheeze, rhinitis and with nasal allergy. Nasal eosinophil cationic protein (ECP) and exhaled breath condensate (EBC) markers (pH, 8-isoprostane, interleukin-1β) were not associated with symptoms or with nasal allergy. In conclusion, FeNO and nasal tryptase reflect allergic inflammation in the respiratory system.     

Calpeptin通过抑制GATA3减轻变应性鼻炎大鼠炎症

摘要 目的：本研究旨在评估钙蛋白酶抑制剂calpeptin减轻变应性鼻炎大鼠炎症的作用并探讨其机制。方法：将20只雄性SD大鼠采用数字表法随机分为4组：正常组（Normal）、变应性鼻炎组（AR）、地塞米松干预AR组（DXMS+AR）、calpeptin干预AR组（Calpeptin+AR）。造模成功后,对大鼠AR症状进行行为学评分,对大鼠鼻黏膜组织切片以HE和PAS染色法观察鼻黏膜病理改变;对大鼠外周血以ELISA法检测总IgE、IL-4、IL-13水平;对大鼠鼻黏膜组织以免疫蛋白印迹法检测GATA3蛋白表达水平。单因素方差分析进行多组间比较,LSD- t检验进行组间两两比较。结果：与Normal组相比,AR组大鼠的鼻部过敏症状、鼻黏膜嗜酸粒细胞计数及外周血总IgE水平均升高,Calpeptin与地塞米松均能减轻气道炎症,减少嗜酸性粒细胞浸润,降低血清中OVA诱导的IgE的生成。探讨机制发现,酶联免疫吸附试验检测Th2细胞因子,与Normal组比较,AR组血清IL-4、IL-13水平均升高（P＜0.05）,而Calpeptin与地塞米松均能降低血清IL-4、IL-13水平（P＜0.05）。免疫蛋白印迹法检测大鼠鼻黏膜GATA3蛋白表达水平显示,与Normal组比较,AR组鼻黏膜 GATA3表达升高（P＜0.05）,而Calpeptin与地塞米松组鼻黏膜 GATA3表达均下降（P＜0.05）。结论：腹腔注射calpeptin能够减轻变应性鼻炎大鼠局部和全身过敏反应,其机制可能下调GATA3表达,影响Th2细胞的分化及细胞因子的分泌有关。

Notch-1 decreased expression contributes to leptin receptor downregulation in nasal epithelium from allergic turbinates

BackgroundAllergic rhinitis is characterized by a remodeling of nasal epithelium. Since the Notch and TGF-β signaling pathways are known to be involved in cell differentiation and remodeling processes and leptin adipokine has already been identified as a marker for homeostasis in human bronchial and nasal epithelial cells of asthmatics, roles played by these pathways have been investigated for chronic allergic rhinitis.MethodsThe leptin/leptin receptor expression has been investigated in a study with 40 biopsies from allergic (AR, n = 18) and non-allergic (C, n = 22) inferior turbinates, using immunohistochemistry, immunofluorescence staining and RT-PCR. In addition, extracts from in vitro samples prepared from primary cells of inferior turbinates as well as in vitro cultured human nasal epithelial RPMI 2650 cells (ATCC-CCL-30) were also tested for leptin expression and activation of the Notch-1 pathway.ResultsWith regards to AR, in vivo expression levels of both leptin and its receptor significantly decreased in comparison to C. Furthermore, leptin receptor mRNA was significantly reduced in AR as compared to C. Immunofluorescence showed an apparent co-expression of leptin receptor with Notch-1, which was not seen with TGF-β. In vitro, in primary turbinate epithelial cells, the expression of leptin receptor and Notch-1 significantly decreased in AR as compared to C. Moreover, in RPMI 2650 cells, leptin receptor expression was shown to be induced by Notch-1 ligand signaling.ConclusionThus, both the leptin and Notch-1 pathways appear to represent markers for epithelial homeostasis in allergic rhinitis.     

Inter-Relationship between Rhinitis and Conjunctivitis in Allergic Rhinoconjunctivitis and Associated Risk Factors in Rural UK Children

Objective

Allergic conjunctivitis (AC) is a common condition, especially in childhood. The extent to which it occurs concurrently with or independently from allergic rhinitis (AR) has not been well described.

Aim

To examine the inter-relationship between rhinitis and conjunctivitis and the epidemiological risk factors for these conditions in a rural UK population.

Methods

Cross-sectional study of rural school children (aged 5–11 years). Parental questionnaires were used to diagnose allergic outcomes (including conjunctivitis, rhinitis and rhinoconjunctivitis), and to collect data on atopic history, demographic and environmental exposures. Odds ratios of allergic outcome by exposure were examined adjusted for age, sex, breastfeeding, family history of allergy, number of older and younger siblings.

Results

Prevalence of conjunctivitis was 17.5%, rhinitis 15.1% and rhinoconjunctivitis 13.0%. Seasonality of symptoms varied by condition: 64.7% of those with conjunctivitis had seasonal symptoms (April-Sept only), 46.7% of those with rhinitis and 92.2% of those with rhinoconjunctivitis. Living on a farm consistently reduced the risk of conjunctivitis (odds ratio 0.47, 95%CI 0.29–0.79, p = 0.004), rhinitis (OR 0.57, 95%CI 0.33–1.01, p = 0.05) and rhinoconjunctivitis (OR 0.57, 95%CI 0.32–1.03, p = 0.06). Exposure to farm animals (particularly in early life), current consumption of unpasteurised milk and playing in a barn or stable significantly reduced the risk of all three conditions.

Conclusion

More children had parent-reported conjunctivitis than rhinitis. The majority of children with either condition also reported symptoms with the other condition. Farmers’ children have less eye and/or nasal symptoms. A number of farming variables linked with the farm microbial environment are likely to be mediating the protective effect.
