慢性胃炎伴良性结节状改变与幽门螺杆菌及淋巴滤泡的关系

目的研究慢性胃炎伴良性结节状改变与幽门螺杆菌（Hp）及胃黏膜淋巴滤泡的关系。方法从2004年7月1日-2005年6月30日行内镜检查患者中，筛选出胃窦黏膜有良性结节样改变者为研究对象，在患者胃窦黏膜处喷洒靛胭脂作色素内镜观察，确定有结节状形态改变，并在有明显结节处取活检组织3块，其中1块立刻作Hp快速试验，判定有无Hp感染；另外2块送病理检查，观察胃黏膜淋巴滤泡形成和淋巴细胞浸润情况，并采用亚甲蓝-硼酸染色法进一步明确诊断Hp感染情况。结果将胃黏膜良性结节状改变的慢性胃炎患者分为三组：结节性胃炎组、萎缩性胃炎组和疣状胃炎组，患者平均年龄分别为（31．OO±11．62）岁、（58．61±12．14）岁和（51．29±12．99）岁，其中结节性胃炎组患者发病年龄最小（P〈0．01）；Hp感染率分别为92．86％、82．56％和69．89％，其中结节性胃炎组的感染率明显高于其他两组（P〈0．01）；有淋巴组织增生所见依次为94．90％、27．9％、18．28％，其中结节性胃炎患者淋巴组织增生明显高于其他胃炎患者（P〈0．01）。伴有结节样改变的萎缩性胃炎患者中萎缩和肠化生百分率分别为100％和59．3％，远高于疣状胃炎组的7．53％、8．60％和结节状胃炎组的4．03％、0．00％。结论在三种常见的胃黏膜良性结节状改变的胃炎中，结节性胃炎与Hp感染及胃黏膜淋巴滤泡形成之间存在密切相关性。可以把Hp感染及淋巴组织滤泡形成和淋巴细胞浸润作为诊断结节性胃炎的病理诊断依据。     

胃窦部幽门螺杆菌清除对萎缩性胃炎病理改变的影响

目的通过对幽门螺杆菌（Hp）相关的萎缩性胃炎病人Hp清除治疗前后胃窦部黏膜病理改变的分析，来确定Hp对其炎症程度、活动性（中性粒细胞浸润）、腺体萎缩和肠上皮化生的影响。方法106例Hp相关的萎缩性胃炎患者接受Hp清除治疗，对其治疗前后胃窦部黏膜的病理变化进行分析，分析标准按96悉尼系统评定。结果在62例治疗成功组中，治疗后胃黏膜的炎症程度及活动性较治疗前明显减轻，但腺体萎缩及肠上皮化生未减轻。在44例治疗失败组中，治疗前后胃黏膜的炎症程度、活动性、腺体萎缩及肠化均没有变化。且随着Hp感染时间的延长，腺体萎缩和肠化还可加重。结论Hp的清除治疗可使萎缩性胃炎患者胃黏膜的炎症程度及活动度减轻，对此类病人应行Hp清除治疗。

HP与慢性胃炎

大量研究资料表明,ＨＰ是慢性胃炎的主要病因,ＨＰ的定植因子和致病因子是慢性胃炎发病的关键。１．ＨＰ的定植因子ＨＰ的自然定植部位是人的胃粘膜,主要位于胃的粘液下和胃粘膜表面上皮之间,与上皮细胞紧密接触。ＨＰ的定植因子为：①螺旋形状及能动性：ＨＰ的螺旋形...     

中国慢性胃炎共识意见(下)(2006,上海)

五、慢性胃炎的转归、萎缩性胃炎的随访与癌变预防29.慢性胃炎可持续存在。由于绝大多数慢性胃炎的发生与幽门螺杆菌感染有关,而幽门螺杆菌自发清除少见,故慢性胃炎可持续存在。30.幽门螺杆菌相关性胃窦炎易发生十二指肠溃疡。多灶萎缩者易发生胃溃疡。部分幽门螺杆菌相关性胃炎(<20%)者可发生消化性溃疡:以胃窦炎症为主者易发生     

慢性胃炎患者胃内pH值相关因素分析

背景：传统观点认为胃酸分泌随年龄增加和胃黏膜萎缩而减少,但也有研究持不同观点。目的：研究慢性胃炎患者胃内pH值与性别、年龄、糖尿病、萎缩和幽门螺杆菌（H.pylori）感染之间的相关性。方法：共纳入67例慢性胃炎患者,采用pH试纸测定胃液pH值,病理切片结合快速尿素酶试验或^13C-尿素呼气试验检测H.pylori感染情况。分析不同因素与慢性胃炎患者胃内pH值的相关性。结果：67例患者中,慢性非萎缩性胃炎患者35例（52．2％）,慢性萎缩性胃炎32例（47．8％）;H.pylori阳性21例（31．3％）,H.pylori阴性46例（68．7％）。平均胃内pH值为2．86,胃内pH值随年龄增长呈升高的趋势（P=0．15）。Logistic回归分析显示胃内pH值与性别（P=0．17）、年龄（P=0．06）、糖尿病（P=0．75）、萎缩（P=0．67）和H.pylori感染（P=0．11）均无相关性。结论：性别、年龄、糖尿病、萎缩和H.pylori感染不是影响慢性胃炎患者胃内pH值的重要因素。     

老年慢性胃炎与幽门螺杆菌感染的关系

本文报道老年慢性胃炎伴幽门螺杆菌（ＨＰ）感染的情况，并与中青年慢性胃炎伴ＨＰ感染组对照。结果表明：老年ＣＡＧ伴ＨＰ感染的发病率较对照组高，而ＣＡＧ又是老年胃癌的癌前病变，因此彻底治疗ＨＰ感染对预防老年ＣＡＧ的癌变有一定的临床意义。     

幽门螺杆菌相关性慢性胃炎的临床和病理特征

对幽门螺杆菌阳性慢必胃炎９９例和阴性慢性胃炎７４例进行了对比研究。结果发现两组慢性胃炎病人在消化不良症状、血清基础胃泌素水平、胃酸分泌及十二指肠胃反流方面差异无显著性，但中度以上十二指肠胃反流者的幽门螺杆菌感染率有减少趋势；在组织病理学方面两组差异有显著性。     

慢性胃炎与幽门螺杆菌感染量关系的探讨

幽门螺杆菌(HP)感染已被公认为是慢性胃炎的主要病因.目前,人们讨论的中心问题是其致病机制,究竟是细菌直接侵袭胃粘膜上皮细胞诱发局部组织损伤,或是细菌产生的毒素作用于局部或远隔区域,或是细菌代谢产物及细菌本身引起的免疫病理反应等尚无定论.本文通过对167例慢性胃炎患者胃窦部粘膜组织快速尿素酶试验及石蜡包埋病理切片,对照观察HP感染量与慢性胃炎程度之间的关系.以期从量的方面了解HP感染与慢性胃炎的关系,进一步加深对慢性胃炎发生机制的理解.

Effect of Hewei-Decoction on chronic atrophic gastritis and eradication of Helicobacter pylori

AIM: To demonstrate the effect of Hewei-Decoction (Decoction for regulating the stomach) on chronic atrophic gastritis (CAG) and eradication of Helicobacter pylori. METHODS: Ninety patients with CAG entering the investigation were divided into six differentiation syndromes, based on their major symptoms and signs. Hewei-Decoction was taken by all the patients orally for 4 or 8 wk. The efficacy was assessed by both the composite accumulation of reduced scores of major symptoms and the eradication of H pylori.X2 test was used to compare the efficacy between H pylori-positive and negative cases, and to disclose the relationship between efficacy and eradication of H pylori. RESULTS: In patients with six different syndrome types, the efficacy of Hewei-Decoction was 91.67% (11/12), 92.86% (13/14), 97.22% (35/36), 87.50% (14/16), 75.00% (6/8), 75.00% (3/4) respectively. The rate of highly efficacious was 58.33% (7/12), 50.00% (7/14), 77.78% (28/36), 62.50% (10/16), 12.50% (1/8) and 25.00% (1/4), respectively. The total efficacy was 91.11% (82/90), and the rate of highly efficacious was 60.00% (54/90). The eradication rate of H pylori was 67.86% (38/56). The therapeutic effect of Hewei-Decoction was better in H pylori positive cases than that in H pylori-negative cases with the total effect of 96.43% vs 82.35% (P<0.05). In 56 H pylori positive cases, the therapeutic effect was better in H pylori eradicated cases than that in H pylori-existent cases with the total effect of 97.37% vs 72.22% (P<0.01). CONCLUSION: Hewei-Decoction is effective in most cases of all the syndrome types. The results indicate that eradication of H pylori is one of the important mechanisms for alleviation of symptoms and signs. Also, the decoction is efficacious in H pylori-negative cases.

Case of early gastric cancer with nodular gastritis

A case of depressed early gastric cancer with nodular gastritis is described. A 47‐year‐old Japanese man was referred to our hospital and admitted for surgical treatment of gastric cancer. Barium upper gastrointestinal study and endoscopy examination showed a 4.5 × 3.0 cm depressed lesion with a deep central ulceration in the anterior wall of the lower corpus. An unusual miliary pattern resembling ‘goose flesh’ was observed endoscopically in the antrum. Biopsy specimens from the tumor showed poorly differentiated adenocarcinoma, and specimens from the antrum showed many lymphoid follicles with a germinal center. Immunoglobulin G antibody and histological tests (Giemsa stain) for Helicobacter pylori were both positive. Early gastric cancer with nodular gastritis was diagnosed and a subtotal gastrectomy was performed. Histological examination of the resected specimen showed a stage I tumor infiltrating a poorly differentiated adenocarcinoma with a depressed lesion in the corpus (type 0 IIc + III) and nodular gastritis in the antrum. The patient is doing well 1 year after surgery.     

Association of Helicobacter pylori infection with atrophic gastritis and intestinal metaplasia

AIMS: To evaluate the effect of Helicobacter pylori infection and aging on atrophy and intestinal metaplasia of the gastric mucosa. METHODS: One hundred and sixty-three patients were divided into three age groups and underwent an upper gastrointestinal endoscopy where no esophagitis, peptic ulcers, or malignancies were detected. Two biopsy specimens were obtained from the anterior and posterior walls of the antrum and of the fundus. These were used to evaluate the grade of gastritis, bacterial culture and histologic evidence of H. pylori infection. RESULTS: Helicobacter pylori infection was found to be directly associated with an increased risk of gastritis grade (odds ratio (OR) = 90 (95% CI; 30-270)). An age of 60 years and older along with H. pylori infection was also strongly associated with an increased risk of atrophy (OR = 6.6, (95% CI; 2.9-15.2)); OR = 9.8, (95% CI; 2.7-35.4)), as was intestinal metaplasia of the gastric mucosa (OR = 5.5, (95% CI; 1.7-17.6)); OR = 7.9, (95% CI; 2.8-46.1)). The prevalence of atrophic gastritis increased with advancing age in H. pylori-infected patients, but no such phenomenon was observed in H. pylori-uninfected patients. The prevalence of intestinal metaplasia significantly increased with advancing age, irrespective of the presence of H. pylori infection. In addition, H. pylori uninfected female patients had a decreased risk of intestinal metaplasia. CONCLUSIONS: These results suggest that atrophic gastritis is not a normal aging process, but instead is likely to be the result of H. pylori infection, while intestinal metaplasia is caused by both the aging process and H. pylori infection. A decreased risk of intestinal metaplasia found in uninfected female subjects may partly explain the lower prevalence of gastric cancer in females than in males.     

Histological analysis of gastritis and Helicobacter pylori infection in patients with early gastric cancer: a case-control study

BACKGROUND AND AIMS: Infection with Helicobacter pylori is associated with an increased risk of gastric adenocarcinoma. However, most patients with H. pylori infection will not develop gastric cancer. The aims of the present study were to examine which histological features, including H. pylori infection, would increase the risk of gastric cancer using a case-control study. METHODS: Three gastric biopsy specimens were taken from 72 patients with early gastric cancer and 72 age- and sex-matched control subjects. The grade of gastritis was examined according to the updated Sydney System. The presence of H. pylori infection was determined by serology and histology. Odds ratio (OR) of developing gastric cancer was calculated for H. pylori positivity and histological features using conditional logistic regression. For patients with H. pylori infection, histological features in cancer patients and control subjects were compared. RESULTS: The OR of the presence of mononuclear cell infiltration in the corpus and intestinal metaplasia in the angulus were significantly elevated. The grade of mononuclear cell infiltration in the corpus and antrum was significantly higher in both types of cancer patients than controls. Glandular atrophy and intestinal metaplasia were increased in patients with intestinal-type cancer in the angulus and antrum. Bacterial density in the corpus and polymorphonuclear cell infiltration in the antrum were increased in patients with diffuse-type cancer. CONCLUSIONS: Severe chronic gastritis induced by H. pylori infection seems to be associated with diffuse-type gastric cancer. Glandular atrophy and intestinal metaplasia, which occur in gastric mucosa with chronic inflammation, are significantly associated with intestinal-type cancer.
