Changes in the severity of atrophic gastritis after Helicobacter pylori eradication

There is a diversity of opinions as to whether Helicobacter pylori eradication leads to the improvement or regression of atrophic gastritis and intestinal metaplasia (IM), which are considered precursor lesions of intestinal type gastric cancer. We have made a 1.5-yr follow-up study after H. pylori eradication, but no significant improvement of atrophy or IM has so far been found. Some other factors than H. pylori may also play an important part in the development and progress of atrophic gastritis. The discrepancy between our data and others may be caused in part by the different methods of assessment of the grade of atrophy and sampling of biopsies.     

小儿幽门螺杆菌感染与慢性胃炎

目的 :研究幽门螺杆菌 (Helicobacterpylori,Hp)感染与小儿不同类型慢性胃炎之间的关系。 方法 :对我院 2 0 0 0年—2 0 0 2年 14 0 4例具有上消化道症状 ,经胃镜检查确诊为慢性胃炎的患儿进行胃黏膜活检 ,分别行病理组织学检查及快速尿素酶试验、改良Giemsa染色找Hp ,同时患儿行血清抗HpIgG检测和 (或 ) 13 碳 尿素呼气试验 (13 C UBT)和 (或 )粪幽门螺杆菌抗原检测 (Helicobacterpyloristoolantigen ,HpSA)。 结果 :14 0 4例慢性胃炎患儿中 ,Hp感染率为 4 5 .3%。各种不同类型慢性胃炎中 ,以胃镜下结节性胃炎和消化性溃疡伴慢性胃炎的患儿Hp感染率为最高 ,分别为 71.2 %和 6 8.0 % ,明显高于其他胃炎组 (P <0 .0 1)。胃黏膜病理组织学改变 ,Hp感染组引起的黏膜炎症程度较重 ,淋巴滤泡形成比例明显较对照组高 (P <0 .0 1)。结论 :小儿时期Hp感染率已较高 ,随年龄增长Hp感染率增高。并且与小儿胃十二指肠疾病关系密切 ,其中与胃镜下结节性胃炎和消化性溃疡伴慢性胃炎最为密切。胃黏膜组织炎症程度越重 ,Hp感染阳性率越高。

Enhanced systemic matrix metalloproteinase response in Helicobacter pylori gastritis

Background. Helicobacter pylori causes chronic gastritis, peptic ulcer disease, and is the most important risk factor for non-cardia gastric cancer, and has been shown to upregulate matrix metalloproteinases (MMPs) in infected gastric mucosa. MMPs are proteolytic enzymes regulated by tissue inhibitors of metalloproteinases (TIMPs).

Aims. We set up this study to find out whether H. pylori gastritis induces systemic MMP response.

Methods. Serum samples were collected from patients undergoing gastroscopy; 26 patients had H. pylori gastritis and 18 were H. pylori-negative controls with normal gastric mucosa. Serum MMP levels were analysed by enzyme-linked immunosorbent assay.

Results. Significantly elevated serum levels of collagenase-2 (MMP-8), gelatinase B (MMP-9), neutrophil elastase (NE), and myeloperoxidase (MPO), and reduced serum levels of gelatinase A (MMP-2) and TIMP-1 were demonstrated in patients with H. pylori gastritis as compared to H. pylori-negative controls. No significant differences were shown in serum matrilysin-1 (MMP-7) levels.

Conclusions. For the first time, we show enhanced MMP-8 response in H. pylori infection together with other neutrophil degranulation products (MMP-9, MPO, NE). Elevated circulating neutrophil degranulation product levels in serum of H. pylori-positive patients reflect accelerated proteolysis and oxidative stress, and may contribute to extraintestinal sequelae, such as cardiovascular diseases.     

胆汁反流性胃炎与幽门螺杆菌的关系

目的 探讨幽门螺杆菌（Hp）感染与胆汁反流性胃炎的关系。方法 采用病理组织学检查和快速尿素酶试验对胃镜和病理组织学诊断明确的104例胆汁反流性胃炎及148例慢性胃炎的患者行Hp检测，比较两组患者Hp检出阳性率。结果 胆汁反流性胃炎组Hp阳性率为22．1％，慢性胃炎组Hp阳性率为43．9％。两组比较差异有显著性意义（P〈0.01）。结论 胆汁反流性胃炎的患者，反流的胆汁可能有抑制和杀灭Hp的作用。     

慢性胃炎患儿家族内幽门螺杆菌亚型感染分析

目的了解慢性胃炎患儿家族幽门螺杆菌（Hp）感染的情况以及家族内幽门螺杆菌亚型的分布。方法采集14例因反复腹痛来我院就诊的患儿及其家庭成员共73例的静脉血,应用幽门螺杆菌金标免疫斑点法和免疫印迹法对患儿及其家族成员进行Hp抗体和亚型的检测。结果慢性胃炎患儿家族中Hp抗体阳性率i00％,免疫印迹Hp亚型抗体阳性率95．9％,其中I型Hp感染占60．3％,Ⅱ型Hp感染占35．6％。I型HP及Ⅱ型Hp感染阳性率在患几与二级亲属之间差异均有统计学意义（P〈0．05）,VacA抗体检出率在有胃肠道疾病组（66．7％）及无胃肠道症状组（35．3％）之间差畀有统计学意义（P〈O．05）。家族成员患Hp感染胃肠道疾病有家庭聚集现象。结论慢性胃炎患儿家族中Hp感染阳性率高,I型Hp感染阳性率随年龄的增加而升高,Ⅱ型Hp感染阳性率随年龄的增加而降低,VacA抗体的分布与消化道症状有关。     

放大胃镜对幽门螺杆菌相关性胃炎的诊断价值

目的探讨放大胃镜对幽门螺杆菌（helicobacterpylori,Hp）相关性胃炎的诊断价值。方法68例慢性浅表性胃炎患者接受了放大胃镜检查,观察胃体大弯集合静脉形态,取活检行病理检查,并进行Hp检测。结果68例患者中Hp阳性20例,Hp阴性48例。Hp阳性者中,18例（90%）表现为D型集合静脉,2例（10%）表现为I型集合静脉;Hp阴性者中,6例（12.5%）表现为D型集合静脉,42例（87.5%）表现为R型或I型集合静脉。两组之间比较,差异有显著性（χ^2为33.81,P〈0.001）。病理学检查结果显示：20例幽门螺杆菌阳性患者中,9例表现为轻度慢性炎症,11例表现为中度慢性炎症;48例幽门螺杆菌阴性患者中,43例表现为轻度慢性炎症或正常胃黏膜,5例表现为中度慢性炎症。两组间病理检查炎症程度差异有显著性（χ^2为13.22,P〈0.001）。结论Hp相关性慢性浅表性胃炎放大胃镜下特点为胃体集合静脉消失,其原因可能与黏膜炎症水肿有关。     

应用光动力治疗幽门螺旋杆菌相关性胃炎的实验研究

Relationship between Helicobacter pylori and antral gastritis and gastroduodenitis]

Morphological data on the biopsies obtained from the antral gastric mucosa of 150 chronic gastritis and gastroduodenitis patients provided grounds for recognition of 3 degrees of gastritis activity. Helicobacter pylori (CP) occurred in the antral gastric portion in 100% of the cases. CP presence and mucosa contamination, plasmocytic infiltration, dystrophic changes in the surface and glandular epithelium were found to correlate. Administration of ampiox in a daily dose of 1.0 g for 10 days resulted in a rapid attenuation of painful and dyspepsia syndromes which ceased on treatment day 7. Endoscopically and morphologically, there were more rapid epithelialization of the erosions and inhibited activity of gastritis compared to the control group. In biopsies obtained on treatment week 3-4 CP was not registered in 67% of cases or was present in much less amounts. The control subjects manifested CP universally, the morphological positive trend was unremarkable.     

慢性萎缩性胃炎治疗的探讨

Esophagitis, gastritis and duodenitis provoked by cure of Helicobacter pylori infection

It has been recently reported that curing Helicobacter pylori (H. pylori) infection may provoke reflux esophagitis. We studied the effect of cure of H. pylori infection on the development of disorders of the upper gastrointestinal (UGI) tract. The estimated incidence of reflux esophagitis, gastric erosions and duodenal erosions after cure of infection was 8.9%, 32.8% and 8.9%. The incidences of reflux esophagitis, gastric erosions and duodenal erosions were 10.0%, 30.0% and 6.7% in patients with gastric ulcer, 2.8%, 36.1% and 27.8% in those with duodenal ulcer and 9.2%, 30.3% and 1.3% in those with atrophic gastritis. Therefore, patients whose H. pylori infection has been cured should carefully be investigated by endoscopy for H. pylori-associated disease.
