Role of corpus gastritis and cagA-positive Helicobacter pylori infection in reflux esophagitis

Considering that the role of Helicobacter pylori infection in gastroesophageal reflux and reflux esophagitis (GERD) is still controversial and that the role of virulence markers of the bacterium has not been evaluated in most studies of GERD, we investigated the association among H. pylori infection with cagA-positive and -negative strains, corpus gastritis, and GERD in a large group of patients by controlling for confounding factors. We studied prospectively 281 consecutive adult patients: 93 with GERD and 188 controls. H. pylori infection status was diagnosed by culture, by the preformed urease test, with a carbolfuchsin-stained smear, and by histology. The cagA status was determined by PCR of H. pylori isolates and gastric biopsy specimens. H. pylori infection was diagnosed in 191 (68.0%) of 281 patients. Among the 93 patients with GERD, 84 presented with mild or moderate esophagitis and 9 presented with severe esophagitis. In the multivariate analysis, the age of the patients and the degree of oxyntic gastritis were associated with GERD. Among the strains isolated from patients with GERD and from the control group, 24.4 and 66.9%, respectively, were positive for cagA (P < 0.001). Compared to infection with cagA-negative strains, infection with cagA-positive H. pylori strains was associated with a more intense gastritis in the corpus (P = 0.001). cagA status (odds ratio [OR] = 0.16, 95% confidence interval [CI] = 0.07 to 0.40), gastritis of the corpus (OR = 0.69, 95% CI = 0.48 to 0.99), and age (OR = 1.04, 95% CI = 1.01 to 1.07) were associated with GERD. In conclusion, the study provides evidence supporting the independent protective roles of cagA-positive H. pylori strains and the degree of corpus gastritis against GERD.     

四联疗法治疗幽门螺旋杆菌相关性十二指肠球炎疗效分析

CagA in Barrett's oesophagus in Colombia, a country with a high prevalence of gastric cancer

BACKGROUND: In the USA, atrophic gastritis and gastric cancer are rare, whereas gastro-oesophageal reflux disease (GERD) is common. Infection with Helicobacter pylori, especially a CagA positive strain, is unusual in patients with GERD/Barrett's oesophagus in the USA. AIM: To examine the relation between Barrett's oesophagus and CagA positive H pylori in Colombia, a country with a high prevalence of CagA positive H pylori associated atrophic gastritis and gastric cancer. METHODS: Helicobacter pylori and CagA status was determined among Colombian patients with long segment Barrett's oesophagus and a control group with simple H pylori gastritis. Helicobacter pylori status was determined using a triple stain and CagA status was determined by immunohistochemistry using a specific rabbit anti-CagA serum. RESULTS: Gastric and oesophageal mucosal biopsies were obtained from 51 patients--39 men (mean age, 57.8 years; SD, 13.1) and 12 women (mean age, 51.8 years; SD, 14.4)--with documented long segment Barrett's oesophagus. The results were compared with 24 Colombian patients with H pylori gastritis without oesophageal disease. Thirty two patients with Barrett's oesophagus had active H pylori infection. CagA status was evaluated in a subset of 23 H pylori infected patients with Barrett's oesophagus, and was positive in eight of these patients compared with 19 of 24 controls (p = 0.01). CONCLUSIONS: Although most Colombian patients with Barrett's oesophagus had H pylori infection, CagA positive infections were unusual. These data illustrate how consistent corpus inflammation reduces acid secretion, which prevents Barrett's oesophagus among those with abnormal gastro-oesophageal reflux barriers.     

幽门螺杆菌根除治疗对幽门螺杆菌阳性的功能性消化不良患者疗效分析

目的 探讨幽门螺杆菌根除治疗对幽门螺杆菌阳性的功能性消化不良（FD）患者疗效。方法 选取2015年1月~2017年1月在本院就诊的幽门螺杆菌阳性的功能性消化不良患者82例,随机分为观察组和对照组。对照组40例采取常规药物（莫沙必利+奥美拉唑）治疗,观察组42例采取四联疗法（兰索拉唑+阿莫西林+克拉霉素+胶体次枸橼酸铋）杀灭幽门螺杆菌治疗,比较两组患者症状改善、临床疗效和不良反应发生情况。结果 两组患者治疗后临床症状积分较治疗前均明显降低,观察组治疗后临床症状积分为（2.71±1.86）分,低于对照组的（8.45±1.92）分,差异有统计学意义（P＜0.05）;观察组不良反应发生率（11.90%）明显低于对照组（22.50%）,差异有统计学意义（P＜0.05）;观察组总有效率（92.86%）明显高于对照组（75.00%）,差异有统计学意义（P＜0.05）。结论 对于幽门螺杆菌阳性的功能性消化不良患者而言,采取四联疗法杀灭幽门螺杆菌,能更加明显改善其临床症状,提高治疗效果,减少不良反应情况,具有临床推广应用价值。

Antimicrobial susceptibility testing of Helicobacter pylori to selected agents by agar dilution method in Shiraz-Iran

PURPOSE: To assess the pattern of antimicrobial susceptibility profile of Helicobacter pylori isolates from patients with gastritis, duodenal ulcer (DU) and gastroesophageal reflux disease (GERD) residing in Shiraz, Iran. METHODS: One hundred and six H. pylori isolates from patients with gastritis, DU and GERD undergoing endoscopy at our university hospitals and clinics were analysed for their antimicrobial susceptibility to metronidazole, clarithromycin, amoxicillin, co-amoxiclav, tetracycline, ciprofloxacin and furazolidone. The minimum inhibitory concentrations were determined by agar dilution method. RESULTS: Overall H. pylori resistance rate was 72.6% to metronidazole, 9.4% to clarithromycin and furazolidone, 20.8% to amoxicillin and 4.7% to tetracycline and ciprofloxacin. No resistance to co-amoxiclav was detected among H. pylori isolates. No significant differences between antimicrobial resistance and clinical outcome were detected. CONCLUSIONS: With regard to the increasing resistance of H. pylori isolates to various antibiotics, susceptibility testing of H. pylori isolates prior to the treatment of infection must be performed to achieve better eradication and to reduce the risk of selection of H. pylori resistant strains.

目的:回顾性分析武汉地区部分居民幽门螺杆菌(Hp)的感染情况,为预防Hp感染和Hp相关疾病的防治提供参考。方法:采用ELISA对1846例武汉地区不同性别、年龄、职业、血型及是否吸烟和出现消化不良症状等居民分组检查其血清Hp抗体,应用SPSS13.0统计软件分析比较各组间Hp感染的检出率差异。结果:被检人群Hp感染总检出率为45.18%;男性为45.77%,女性为44.50%(P>0.05);体检健康者Hp检出率为33.18%。不同年龄组Hp检出率不同,小于15岁组最低,为26.32%,之后逐渐升高,至60岁以上组达到61.17%。O型血者Hp检出率较其他血型组显著增高(P<0.05),有消化不良症状组Hp检出率(64.90%)显著高于无消化不良组(44.52%,P<0.05)。结论:武汉地区居民Hp感染较为常见。Hp感染与年龄、血型、消化不良症状密切相关。     

Lymphocytic esophagitis: a chronic or recurring pattern of esophagitis resembling allergic contact dermatitis

Lymphocytic esophagitis (LE) is characterized by intraepithelial lymphocytes (IELs) and spongiosis, resembling contact dermatitis. LE has been defined as high numbers of IELs and no or rare granulocytes and was found in young patients and in association with Crohn disease (CD). We reviewed the medical records of 42 LE cases. Cases were divided into severe (IELs in interpapillary and peripapillary fields) and mild (IELs in peripapillary fields) LE. The control group included specimens from 34 consecutive esophageal biopsy cases. Mean ages were similar (LE, 44 years; control subjects, 43 years). CD was present in 5 LE cases (12%) and 1 control case, an insignificant difference. Of patients with LE, 14 (33%) had an allergy; 11 (26%), gastroesophageal reflux disease (GERD); 4 (10%), Helicobacter pylori gastritis; and 18 (43%), dysphagia. No differences were found in clinical features between LE and control cases, except GERD was less common in severe LE (6/30 [20%]) than in control cases (17 [50%]). No patient with LE had celiac disease. No medications were common among LE cases. Patients with LE are statistically no more likely than control subjects to have CD. We found no association between LE and any clinical condition or symptom. Based on sequential biopsies in 7 patients, LE seems to be a chronic disease.     

Helicobacter pylori and gastroesophageal reflux disease

The latest accessible data indicate, that Helicobacter pylori (H.p.) infection, particularly by cagA-positive strains, protects against the development of gastroesophageal reflux disease (GERD) and its complications. Various epidemiological, pathophysiological and clinical studies demonstrate this protective effect, which is dependent on the extent of H.p. induced gastritis. Severe corpus gastritis may cause a profound reduction of acid secretion. In regard to acute or chronic PPI therapy of GERD the biological antisecretory effect of H.p. is of minor benefit. Development of atrophic gastritis in patients with GERD treated chronically with PPI is still uncertain. On account of the protective effect of H.p. against GERD, it is prudent to reserve H.p. eradication for the well-established indications.
