幽门螺杆菌根除治疗对胃肠道微生态影响的研究进展

幽门螺杆菌( H. pylori)感染是常见的慢性感染之一,京都共识和Maastricht Ⅴ共识均建议对 H. pylori感染者进行根除治疗,除非有抗衡因素的存在,并且推荐质子泵抑制剂(PPI)、铋剂和2种抗菌药物组成 H. pylori四联根除方案,疗程...     

三联疗法根除幽门螺杆菌治疗对肠道微生态的影响

目的 探讨抗幽门螺杆菌(Hp)治疗对患者肠道菌群状态(肠道微生态)及耐药性的影响。方法 分别称取60例患者治疗前后新鲜粪便0．5g，选择肠道菌群中具代表性的4种需氧菌和6种厌氧菌分别进行需氧和厌氧培养，从培养出的菌落中挑选相同的菌株进行治疗前后药敏试验。结果 (1)治疗后肠道菌群中肠杆菌、葡萄球菌、拟杆菌、双歧杆菌、消化球菌、梭菌、乳杆菌、真杆菌均较治疗前明显降低(P＜0．05)；(2)治疗后肠道菌群中大肠埃希氏菌、消化链球菌、赛氏葡萄球菌、普氏梭杆菌、肺炎致病性链球菌群、产气真杆菌等对庆大霉素、红霉素、环丙沙星、特美丁、头孢噻肟钠等药耐药率明显增加，且存在多重耐药(P＜0．05)；(3)治疗后超广谱β—内酰氨酶阳性的消化链球菌、表皮葡萄球菌、普氏梭杆菌、肺炎致病性链球菌群、赛氏葡萄球菌等较治疗前分别增加26．2％、33．3％、28．6％、35．3％、28．6％。结论 三联抗Hp治疗后肠道菌群失调、耐药菌株的增加、传播与扩散对广大人群存在潜在危险。

根除幽门螺杆菌治疗对肠道微生态环境的影响

幽门螺杆菌（HP）在消化性溃疡及慢性胃炎的发病中有重要作用,近十余年来,临床上对多种胃肠道疾病开展了根除HP治疗。现将根除HP治疗对肠道微生态环境的影响及意义分析如下。     

根除幽门螺杆菌治疗十二指肠溃疡46例

对十二指肠溃疡 (ＤＵ )传统的治疗方法主要是降低胃酸。近年来人们逐渐发现幽门螺杆菌 (Ｈｐ)在消化性溃疡的发病机制中起着重要作用 ,并直接影响溃疡的愈合和复发 ,它可能是引起ＤＵ的主要因素。大量研究表明 ,单独应用根除Ｈｐ的治疗方案而不用制酸剂治疗ＤＵ即能达到满意效果 ,且使ＤＵ复发率大为降低。为此 ,选择安全、经济、方便的高Ｈｐ根除率的方案意义重大。1　资料与方法1 1　病例选择 :4 6例患者 ,男 37例 ,女 9例 ,平均年龄 38 6岁。经胃镜检查和胃粘膜快速尿素酶检测证实有Ｈｐ感染的活动性ＤＵ ;1个月内无服用非甾体类抗炎药…

功能性消化不良患者抗幽门螺杆菌治疗后肠道微生态变化及意义

自Ｍａｓｈａｌｌ发现幽门螺杆菌 (Ｈｅｌｉｃｏｂａｃｔｅｒｐｙｌｏｒｉ,Ｈｐ)十几年来 ,根据Ｈｐ治疗一直是研究热点之一 ,并在世界范围内开展了广泛的根除Ｈｐ治疗。然而 ,从临床上我们发现 ,目前抗Ｈｐ治疗方案并非对所有患者都有肯定的价值 ,我们可能低估了其可能产生的不利影响。为此 ,我们研究了 5 0例功能性消化不良 (ｆｕｎｃｔｉｏｎａｌｄｙｓｐｅｐｓｉａ ,ＦＤ)患者抗Ｈｐ治疗前后肠道菌群状态及耐药性变化。一、材料与方法1.对象 :ＦＤ患者 5 0例 ,年龄为 19～ 5 0岁 ,男 2 0例 ,女30例 ;均经临床及胃镜检查 ,符合ＦＤ诊断标…     

微生态制剂联合三联疗法治疗老年人幽门螺旋杆菌感染56例

目前推荐的根除幽门螺杆菌(Hp)治疗方案主要为质子泵抑制剂(PPI)和(或)铋剂联合两种抗生素的经典三联、四联疗法,但在根除Hp治疗过程中不断出现的耐药、不良反应发生率的升高及根除率的下降,尤其在老年患者中更为突出。近年来有研究显示,微生态制剂有杀灭和抑制Hp的作用。本文探讨经典三联根除Hp疗法联用微生态制剂的疗效。     

左氧氟沙星三联疗法根除幽门螺杆菌临床观察

观察左氧氟沙星、埃索美拉唑、阿莫西林三联疗法对幽门螺杆菌（npylori）治疗失败后的患者复治的疗效,选取62例经抗Mpylori一线治疗后^14C-尿素呼气试验证实幽门螺杆菌感染仍阳性的患者参与研究,将患者随机分为治疗组和对照组,治疗组34例,用左氧氟沙星、埃索美拉唑、阿莫西林三联疗法。对照组28例,用奥美拉唑、铋剂、阿莫西林、甲硝唑四联疗法。两组对再次治疗病例H．pylori根除率分别为85．29％、75％。差异无统计学意义（P〉0．05）。结果表明左氧氟沙星、埃索美拉唑、阿莫西林三联疗法对H．pylori治疗失败后的H．pylori根除率与以铋剂为基础加质子泵抑制剂（PPI）的四联疗法对H．pylori的根除率接近,但用药简单,患者易于接受。     

根除幽门螺杆菌对胃增生性息肉的作用

目的　探讨根除幽门螺杆菌(Hp)对胃增生性息肉的作用。方法　将胃增生性息肉 (息肉直径 3~10mm)合并Hp感染的 48例患者随机分为治疗组及对照组 (各 24例 )。治疗组患者接受四联治疗,包括质子泵抑制剂(奥美拉唑或兰索拉唑)、克拉霉素、枸橼酸铋及替硝唑,疗程 2周。对照组仅接受替普瑞酮治疗。受试者在纳入试验前及治疗结束后 1~12个月接受定期胃镜检查和Hp测定。结果　治疗组和对照组各有 22例及 21例患者完成整个研究。治疗组有 19例 ( 86. 4% )Hp得到根除,在用药后 1~12个月,平均(6. 5±1. 1)个月随访中,Hp根除者中 15例(78. 9)胃息肉消失。而在试验开始后12个月,对照组患者的胃息肉和Hp情况未发生变化 (P<0. 01 )。结论　大多数胃增生性息肉在根除Hp后消失,患者如同时患有胃增生性息肉和Hp感染,在行息肉摘除术前可先尝试Hp根除治疗。     

Helicobacter pylori infection in children

Helicobacter pylori was sought prospectively by culture of antral biopsy, histology and serology (IgG and IgA) in 440 consecutive endoscopies on children to determine the prevalence, clinical presentation and histological features of H. pylori infection in our population. Twenty-eight patients had H. pylori (8% overall). The mean age of infected patients was significantly higher than that of non-infected patients (P less than 0.0001). No patient under 5 years of age had H. pylori isolated. Overall, there was no significant difference in clinical presentation between those with and those without H. pylori infection, but 23% of patients 5 and 26 years of age who presented with abdominal pain as the indication for their endoscopy had H. pylori isolated. Macroscopic changes ranged from no abnormality to frank ulceration, but the typical antral mamilliform changes were 100% predictive of infection. Fifty-eight per cent of patients with duodenal ulcers, but only 17% with gastric ulcers had H. pylori infection. Histological gastritis was present in 144 patients (including all H. pylori positive patients). None of the patients with another definable cause for gastritis had H. pylori isolated. In conclusion, H. pylori is an important cause of primary gastritis in our population, occurring in children over 5 years of age. Culture of an antral biopsy should be performed in children over this age undergoing endoscopy for the investigation of abdominal pain and, more particularly, in those with peptic ulceration.     

十二指肠胃化生与幽门螺杆菌感染

本文调查了155例十二指肠溃疡旁粘膜的组织病理学变化,并与对照组相比较。结果显示:溃疡旁组织炎症、胃化生和Hp检出率分别为69.7％、75.5％和24.5％,显著高于对照组的18.8％、10.4％和4.2％(P<0.01)。Hp在胃化生组织中的检出率为32.8％,81例不伴胃化生的粘膜中均未检出Hp(P<0.01)。透射电镜观察胃化生有其特征性改变。提示胃化生可能是溃疡形成的基础,Hp在化生区定植并非是产生溃疡的唯一直接因素,还可能通过其他复杂环节间接起作用。     

Effect of Clostridium butyricum on fecal flora in Helicobacter pylori eradication therapy

AIM: To investigate the effect of probiotic bacterium, Clostridium butyricum MIYAIRI 588 strain (CBM) on the changes of the fecal flora in Helicobacter pylori (H pylori) treatment. METHODS: Thirty-five patients with gastric or duodenal ulcers positive for H pylori were randomized either to 1 wk amoxicillin, clarithromycin, lansoprazole (Group 1) or to the same regimen supplemented with CBM 7 d ahead of the triple therapy (Group 2). Stool samples were collected before and 2, 4, 7, 15, and 22 d after the starting eradication therapy, and were examined intestinal flora. Patients were required to keep a diary record of their condition. RESULTS: Obligate anaerobes decreased significantly on d 2, 4, 8 and 15 in Group 1. On the other hand, they did not decrease significantly in Group 2. The Escherichia coli was dominant bacterium in Enterobacteriaceae, but that was replaced by other species such as Klebsiella and Enterobacter after eradication in Group 1. The change was suppressed in Group 2. Abdominal symptoms were less frequent in Group 2 than in Group 1. CONCLUSION: The combined use of CBM reduced the changes in the intestinal flora and decreased the incidence of gastrointestinal side effects.     

胃十二指肠疾病幽门螺杆菌检出的意义

目的:研究幽门螺杆菌(Hp)与消化性溃疡及慢性胃炎致病的关系。方法:因胃十二指肠疾病而做胃镜的患者,采取胃粘膜进行组织快速检菌,一分钟尿素酶(1min UT)试验和血清间接免疫荧光法进行检菌分析。结果:对5000例胃及十二指肠疾病Hp的组织检出率为88.1％。1min UT阳性率为62.9％,两种检菌法有显著差异(P<0.01)。十二指肠溃疡Hp检出为96.0％,胃癌和萎缩性胃炎Hp感染率为50.0％和59.2％,而1min UT只有41.5％阳性率。结论:胃癌和萎缩性胃炎均有粘膜层萎缩,腺体减少、粘液分泌功能降低,Hp茵不能适应强酸环境下生存。十二指肠溃疡和慢性胃炎多伴引起幽门口水肿和幽门变型,胃排空减缓。是导致Hp茵高检出率的重要因素。     

消化性溃疡与幽门螺杆菌L型感染相关性研究

目的　探讨消化性溃疡 (PU)与幽门螺杆菌 L型 (HP- L )感染的关系。方法　取 386例 PU患者胃窦、胃体及十二指肠粘膜组织 ,常规切片后以革兰氏染色和免疫组化染色镜检 HP- L 型细菌 ,并计算检出率。结果　 HP- L 型检出率为 5 3.37% ,其中革兰氏染色和免疫组化染色检出率分别为 5 6 .73%、5 4 .2 9% ,差异无显著性(P>0 .0 5 ) ;胃溃疡、十二指肠溃疡 HP- L 型检出率分别为 5 8.33%、5 5 .5 0 % ,差异无显著性 (P>0 .0 5 ) ;男女患者HP- L 检出率前者 (6 1.18% )明显高于后者 (38.17% ) (P<0 .0 1) ;30岁以下、30岁～、4 0岁～、5 0岁～患者 HP- L检出率依次为 32 .0 5 %、4 1.94 %、5 9.18%、71.79% ,差异显著 (P<0 .0 1)。结论　 PU患者 Hp- L型感染率较高 ,且男性高于女性 ,HP- L型检出率随年龄增长而增高。 PU患者 HP- L型变异可能是导致溃疡迁延不愈、反复发作的重要原因之一     

Treatment of Helicobacter pylori

INTRODUCTION Using an evidence-based approach this review discusses the current treatment of Helicobacter pylori infection in patients with peptic ulcer disease, functional (non-ulcer)dyspepsia or gastro-oesophageal reflux disease (GORD).It also briefly addresses the potential role of eradication of H . pylori in preventing gastric cancer .     

Patients with Helicobacter pylori positive and negative duodenal ulcers have distinct clinical characteristics

AIM: To assess the clinical characteristics of Helicobacter pylori (H pylori) negative duodenal ulcer. METHODS:Patients with an endoscopic diagnosis of duodenal ulcer between 1996 and 2002 were included in the present study. Patients were considered to be negative for H pylori, if both histological examination and rapid urease test of biopsy specimens were negative. A comparison was made between patients with H pylori positive and negative duodenal ulcers. RESULTS: A total of 1 343 patients were studied. Their mean age was 54.7±0.5 years. There was a male preponderance (M:F=2.5:1). Three hundred and ninety-eight patients (29.6%) did not have H pylori infection. The annual proportion of patients with H pylori negative duodenal ulcers increased progressively from 1996 to 2002. On multivariate analysis, patients with H pylori negative duodenal ulcer were more likely to be older, have concomitant medical problem, pre-existing malignancy, recent surgery, underlying sepsis, or taken non-steroidal anti-inflammatory drugs. In terms of clinical presentations, patients with H pylori negative duodenal ulcer were more likely to present with bleeding, multiple ulcers and larger ulcers. CONCLUSION:The proportion of patients with H pylori negative duodenal ulcers is on the rise because of a continued drop in incidence of H pyloripositive duodenal ulcers in recent years. Such patients have distinct clinical characteristics and it is important to ascertain the H pylori status before starting eradication therapy.     

幽门螺杆菌感染对胃上皮细胞凋亡的影响

本文采用切口末端标记方法前瞻性观察了16例正常胃牯膜标本和31例幽门螺杆菌阳性胃炎患者抗幽门螺杆菌治疗前后胃窦部上皮细胞凋亡的变化。结果表明,幽门螺杆菌感染者的凋亡指数(0.7044)明显高于正常对照者(P<0.005);幽门螺杆菌根除后凋亡指数由0.7624降至0.1159(P<0.005),而持续阳性者则无明显降低;凋亡指数与胃炎程度无关。提示幽门螺杆菌能促进胃上皮细胞凋亡,这可能是幽门螺杆菌引起胃癌和溃疡的重要机理。
