目的 探讨幽门螺杆菌(H.pylori)感染与哮喘发病的影响,分析H.pylori感染对免疫功能指标、辅助性T细胞1(Th1)/辅助性T细胞2(Th2)和辅助性T细胞17(Th17)/调节T细胞(Treg)平衡的影响。方法 收集2020年1月至2021年12月,在南阳市第一人民医院接受治疗的哮喘病儿(哮喘组)142例,及健康儿童(对照组)120例。采用14C呼气试验检测H.pylori感染情况,比较哮喘组和对照组中H.pylori阳性率。哮喘病儿根据是否合并H.pylori感染,分为H.pylori阴性组和H.pylori阳性组,比较两组间免疫功能指标、Th1/Th2及Th17/Treg。结果 哮喘组H.pylori阳性率10.6%显著低于对照组32.5%(χ2=19.13,P<0.001)。轻度哮喘组、中度哮喘组和重度哮喘组H.pylori阳性率分别为22.2%(10/45)、6.6%(4/61)和2.8%(1/36),三组间比较均差异有统计学意义(χ2=9.82,P=0.007),且重度哮喘组H.pylori阳性率低于轻度哮喘组(χ... 相似文献

Treatment of Helicobacter pylori infection in children 总被引:1,自引:0,他引:1
Gilger MA 《Current pharmaceutical design》2000,6(15):1531-1536
The majority of Helicobacter pylori (H. pylori) infections appear to be acquired during childhood. Despite this fact, the natural history of H. pylori infection in children, such as the mode of acquisition, the clinical symptoms and signs of infection and the appropriate treatment, is poorly understood. There is no consensus regarding which children with H. pylori infection deserve treatment nor is there agreement on the appropriate treatment regimen. This stems from the lack of controlled studies into H. pylori infection during childhood. For example, there have been no controlled studies to determine effective treatment of H. pylori infection in children. Although published guidelines for the treatment of childhood H. pylori infection do not currently exist, there is reasonable evidence to support treatment in children with gastric or duodenal ulcer, gastric MALT (mucosa-associated lymphoid tissue) lymphoma and atrophic gastritis. There is no strong evidence to recommend treatment of children with H. pylori infection and recurrent abdominal pain, asymptomatic infection, children in chronic care facilities and children who have a family member with H. pylori infection. Current evidence suggests that single and dual therapy regimens for H. pylori infection in children are not effective. Triple therapy , generally the combination of 2 antibiotics and a proton pump inhibitor, given two times daily for 2 weeks appears to offer the best current treatment. 相似文献

Helicobacter pylori infection is mainly acquired during childhood: it is recognised as a cause of gastritis and peptic ulcer and it has been classified as a group A carcinogen by the World Health Organisation. The exact mode of transmission is as yet unknown. The aim of this review was to analyse the literature about H. pylori infection in paediatric patients. The large diffusion of H. pylori infection in paediatric patients, the absence of a specific clinical feature, the new non-invasive methods for diagnosis and follow-up, which are still not validated and the different therapeutic schedules have led to the necessity of determining the real clinical outcome in affected children and adolescents. The scope of the review was to identify better eradication therapy and the most important factors in treatment failure. The international literature has shown the importance of culture, antibiograms, the compliance of families and patients and the use of probiotics during triple eradication therapy. The review paid attention to the management, diagnostic techniques and therapy of this infection in paediatric patients. 相似文献

目的探讨幽门螺杆菌感染与儿童过敏性紫癜相关性情况。方法选取我院2015年6月~2017年6月收治的30例过敏性紫癜儿童作为观察组,同期门诊健康体检56例儿童作为对照组,以~(13)C尿素呼气试验阳性作为判定幽门螺杆菌是否发生感染的标准,依据治疗措施不同再将观察组~(13)C尿素呼气试验阳性儿童分为治疗A组(常规性的治疗)10例和治疗B组11例(抗幽门螺杆菌感染治疗)。结果观察组儿童幽门螺杆菌感染发生率高于对照组,治疗B组幽门螺杆菌感染患儿临床治疗总有效率高于治疗A组,复发率低于治疗A组,差异有统计学意义(P<0.05)。结论幽门螺杆菌感染与儿童过敏性紫癜存在一定的相关性,进行抗幽门螺杆菌感染治疗,可以提高儿童过敏性紫癜临床效果,值得推广应用。 相似文献

Relationship between gastric mucosal IL-8 levels and histological gastritis in patients with Helicobacter pylori infection 总被引:3,自引:0,他引:3
Xuan J Deguchi R Yanagi H Ozawa H Urano T Ogawa Y Fukuda R Kojima S Nishina M Sudo H Kijima H Koga Y Takagi A 《The Tokai journal of experimental and clinical medicine》2005,30(2):83-88
To determine the role of host immune responses in H. pylori infection, we examined the relationship between gastric mucosal IL-8 levels and histological gastritis in patients with H. pylori infection. Biopsy tissue obtained from 99 patients were homogenizedand mucosal IL-8 levels measured by ELISA. The gastric mucosal IL-8 levels in both the antrum and corpus were higher in patients with H. pylori than in H. pyloi negativepatients. IL-8 levels in the corpus but not the antrum correlated with the severity of the atrophy. The IL-1B polymorphism had no influence on the degree of IL-8 production. These findings indicate that IL-8 production is independent of IL-1B polymorphisms and IL-8 may play an important role in the development of atrophic gastritis. 相似文献

The presence of lymphoid tissue in the gastric mucosa is virtually pathognomonic of Helicobacter pylori infection. This lymphoid tissue has mucosa–associated lymphoid tissue (MALT) characteristics suggesting that H. pylori infection may represent a stimulus for the growth of gastric MALT lymphoma. H. pylori can be detected in more than 90% of patients with low–grade gastric MALT lymphoma supporting the aetiological role of the organism. The strongest evidence for the significance of H. pylori in the pathogenesis of low aetological–grade gastric MALT lymphoma is provided by clinical studies showing that cure of H. pylori infection is followed by a complete regression of these tumours in most patients. This paper reviews the current knowledge about antibacterial treatment of low–grade gastric MALT lymphoma, and immunological and molecular aspects in the pathogenesis of the disease. 相似文献
