OBJECTIVES: 1. To determine the prevalence of Helicobacter pylori (H. pylori) infection in patients with gastroesophageal reflux disease (GERD), and to compare it with that in a control group. 2. To study the percentage of H. pylori-positive GERD patients according to different grades of esophagitis. MATERIAL AND METHODS: H. pylori prevalence by serological tests was compared among 692 patients with GERD and 200 healthy volunteer controls. Subsequently, the percentage of H. pylori was analyzed in the different grades of esophagitis, according to the Savary-Miller classification. RESULTS: no differences between the GERD group and control group were detected regarding age (50.5+/-14.7 vs 50.7+/-16.4 years, ns) and sex (63 vs 66% of men, ns); on the other hand the prevalence of H. pylori was 40% in the GERD group facing 66% in the control group, p <0.01. There were no differences in H. pylori prevalence according to the different grades of esophagitis, but logistical regression analysis showed that the absence of H. pylori infection was associated with the presence of grade IV esophagitis. CONCLUSIONS: the prevalence of H. pylori infection in GERD patients is lower than that of the general population, and its absence is associated with more severe grades of the disease. These results indicate that H. pylori plays a protective role against GERD. 相似文献

OBJECTIVE: The etiology of inflammation below the normal Z-line is an area of intense debate. Some suggest this is the earliest change of chronic gastroesophageal reflux disease (GERD), whereas others indict Helicobacter pylori (H. pylori) as the main cause. The aim of this study was to evaluate the relationship among inflammation of gastric cardiac mucosa (carditis), H. pylori infection, and intestinal metaplasia in patients with GERD and Barrett's esophagus compared with age-matched controls. METHODS: Patients with GERD and Barrett's esophagus were compared with controls undergoing endoscopy for a variety of other conditions. Endoscopic biopsy specimens from the gastric cardia (obtained on retroflexed view), fundus, and antrum were evaluated for inflammation, H. pylori infection, and intestinal metaplasia. RESULTS: The prevalence of H. pylori infection did not significantly differ among the study populations: controls (42%), GERD (33%), and Barrett's esophagus (27%) (p = 0.20). However, the prevalence of carditis significantly decreased from the control group (30%) to those with GERD (23%) and Barrett's esophagus (11%) (p = 0.03). Overall, 42 of 51 (82%) patients with carditis had H. pylori; all had pangastritis. The prevalence of cardia intestinal metaplasia also significantly decreased from the control group (15%) to those with GERD (4%) and Barrett's esophagus (0%) (p = 0.003). Of 13 patients with cardia intestinal metaplasia, 12 had carditis, 10 had H. pylori infection, and seven had intestinal metaplasia elsewhere in the stomach. CONCLUSIONS: Inflammation of gastric cardiac mucosa decreases in prevalence from controls to patients with GERD and Barrett's esophagus and correlates strongly with H. pylori infection. Cardia intestinal metaplasia is associated with H. pylori-related cardiac inflammation and intestinal metaplasia elsewhere in the stomach. 相似文献

BACKGROUND: The aim of this study was to evaluate the prevalence of Helicobacter pylori infection and the characteristics of gastritis and symptoms of patients with erosive and nonerosive gastroesophageal reflux disease (GERD). METHODS: We studied 202 consecutive patients with a diagnosis of GERD (symptoms score and endoscopy): group A (n = 110), erosive GERD; group B (n = 92), nonerosive GERD; 200 patients with upper abdominal complaints without abnormalities at endoscopy (functional dyspepsia, group C); and 200 asymptomatic controls tested for H. pylori serum antibody (group D). Antral and body biopsy specimens were taken for histology and the rapid urease test in groups A, B, and C. RESULTS: The prevalence of H. pylori infection was higher in groups B and C (62% and 55%, respectively) than in A and D (36% and 40%) (P < 0.05). In positive patients H. pylori colonization and gastritis grade scores in the gastric body were higher in nonerosive than in erosive GERD and functional dyspepsia (P < 0.05). No differences in H. pylori colonization or gastritis grades were found in the antrum. Fifty-nine patients with nonerosive GERD (64%) and 42 with erosive GERD (38%) showed other dyspeptic symptoms associated with reflux symptoms (P < 0.05). CONCLUSIONS: H. pylori prevalence is higher in patients with nonerosive GERD than in normal subjects and in patients with erosive GERD and similar to that of patients with dyspepsia. Patients with nonerosive GERD often show dyspeptic symptoms and higher H. pylori colonization and inflammation grades in the proximal stomach. Our data support the hypothesis that in GERD H. pylori gastritis may, on the one hand, protect against the development of esophageal erosions and, on the other, contribute to the esophageal hypersensitivity to acid which is a feature of GERD. 相似文献

BACKGROUND/AIMS: The prevalence of gastroesophageal reflux disease (GERD) in Korea was believed to be low until now. Korea is now believed to be on the evolving stage of GERD in its' prevalence. The aims of this study were to evaluate the epidemiologic and clinicopathologic characteristics among the subgroups of GERD i.e. non-erosive GERD (NERD), erosive GERD (ERD) and Barrett's esophagus (BE), and the role of Helicobacter pylori (H. pylori) infection in the pathogenesis of GERD. METHODS: A total of 253 patients with typical symptoms of GERD who underwent EGD were enrolled from October 2002 to January 2004. Patients were grouped as NERD, ERD or BE based on the symptoms and endoscopic findings. BE was histologically confirmed if necessary. Various clinical parameters including the status of H. pylori infection were analyzed. RESULTS: Among 253 patients, 106 patients were classified as NERD while 116 and 31 patients were classified as ERD and BE group respectively. BE and ERD group showed no gender predilection while NERD showed female preponderance (2.31:1, p < 0.05). NERD group were younger (49.57 y.o.) than BE (57.87 y.o.) and ERD (52.30 y.o.) group. About three quarters of the patients of erosive esophagitis were LA-A (74.2%) grade. This suggests the mild nature of erosive esophagitis in Korea. ERD showed significantly higher BMI (kg/m2) compared to NERD (p < 0.05). Hiatal hernia was frequently associated with BE and ERD (p < 0.05), but less frequently in NERD. Overall H. pylori positivity among GERD was significantly lower than the age and gender matched control group (p < 0.05). CONCLUSIONS: Subgroups of GERD in Korea showed different epidemiologic and clinical characteristics. Lower rate of H. pylori infection among GERD group may reflect the protective role of H. pylori infection regarding GERD prevalence in Korea. 相似文献

OBJECTIVES: The relationship between Helicobacter pylori infection and gastroesophageal reflux (H. pylori) disease (GERD) is controversial. In Asian populations, the prevalence of H. pylori infection is high and GERD is relatively uncommon. The aim of this study was 1) to test the hypothesis that H. pylori protects the esophagus against GERD, and 2) to study the pattern of H. pylori colonization and gastritis in GERD. METHODS: We conducted a prospective case-control study in which patients with GERD and asymptomatic controls were compared for the prevalence of H. pylori infection. Diagnosis of GERD was based on symptoms of heartburn that improved with acid-suppressive therapy and/or endoscopic evidence of erosive esophagitis. H. pylori status was determined by serology and, when endoscopy was indicated, was confirmed by rapid urease test and histology. Gastric biopsies were examined under hematoxylin and eosin and Giemsa stains. Density of H. pylori colonization and activity of gastritis at different parts of stomach were graded and compared according to Updated Sydney system. RESULTS: A total of 106 patients with GERD and 120 age- and sex-matched, asymptomatic controls were enrolled. The prevalence of H. pylori infection was significantly lower in GERD patients (31%) compared with controls (61%, p < 0.001, odds ratio 0.229, 95% confidence interval 0.13-0.41). H. pylori-infected GERD patients showed significantly more severe gastritis in the antrum than in other parts of stomach (mean inflammatory scores: antrum; 3.3 +/- 1.63*, body; 1.85 +/- 1.31; fundus; 1.65 +/- 0.58; cardia, 1.65 +/- 1.39; *p < 0.005). H. pylori colonization was found less commonly and at lower density at the cardia compared with other parts of the stomach. CONCLUSIONS: H. pylori infection protects against the development of GERD, and carditis is unlikely to play an important role. 相似文献

BACKGROUND: The role of H. pylori infection in GERD is highly controversial. Our aim was to investigate the relationship between reflux esophagitis and H. pylori infection in Jordanian subjects and to examine the gastric site for H. pylori that is most strongly associated with reflux esophagitis. METHODS: During endoscopy two biopsies from the cardia and another two biopsies from the antrum were taken from 100 consecutive patients with reflux esophagitis (RE group) and from a sex- and age-matched group of 50 patients, who were referred to the endoscopy unit for evaluation of upper gastrointestinal symptoms and whose endoscopic findings were normal (control group). The biopsies were examined histologically for the presence of gastritis and H. pylori. RESULTS: Antral histological gastritis, Barrett's esophagus and hiatus hernia were significantly more common in the RE group than in the control group. Out of the 100 patients, 68 (68%) in the RE group and 26 of 50 (52%) in the control group were found to have H. pylori infection. The presence of H. pylori in both antral and cardiac biopsies was significantly more frequent in patients of the RE group. Forty-four patients in the RE group had positive H. pylori in both antral and cardiac biopsies (44%), while only 12 out of 50 patients of the control group (24%) had positive H. pylori in both biopsies. In the control group the prevalence of H. pylori in the antrum was similar to that of patients of the RE group (52% vs. 59%), but colonization of H. pylori in the cardia was significantly much lower than that of the RE group (24% vs. 53%; P = 0.0007). CONCLUSIONS: The increased prevalence of H. pylori colonization in the cardia is associated with reflux esophagitis and further controlled clinical study is required to show the impact of H. pylori eradication in patients with reflux esophagitis. 相似文献

OBJECTIVES: Eradication of Helicobacter pylori (H. pylori) infection markedly reduces the recurrence of duodenal and gastric ulcers. However, there is little information regarding its efficacy in resolving dyspeptic symptoms in ulcer patients. The primary aim of this study was to assess the effect of eradicating H. pylori infection on dyspeptic symptoms in ulcer patients. The secondary aim was to identify predictors of symptomatic response to H. pylori eradication. METHODS: A total of 97 dyspeptic patients with active duodenal and/or gastric ulceration associated with H. pylori infection and unrelated to NSAID use had the severity and character of their dyspeptic symptoms measured before and again 1-3 yr after H. pylori eradication therapy. RESULTS: Pretreatment, the median dyspepsia score was 12 (4-16). Posttreatment, 55% of those eradicated of H. pylori had resolution of dyspepsia (score <2) compared with 18% of those not eradicated of the infection (95% CI for difference, 11-62%). Of the ulcer patients 31% had symptoms and/or endoscopic evidence of coexisting gastroesophageal reflux disease (GERD) at initial presentation and this influenced the symptomatic response to eradication of H. pylori. Of the 22 patients with heartburn or acid reflux as the predominant presenting symptom, but no endoscopic esophagitis, only 27% experienced resolution of dyspepsia after H. pylori eradication, compared with 68% of the 59 without those as predominant symptoms (95% CI for difference, 18-63%). Only one of the five patients with coexisting endoscopic esophagitis at initial presentation experienced resolution of dyspepsia after H. pylori eradication. Symptomatic benefit was unrelated to time lapsed since the infection was eradicated. Only three of 50 subjects developed de novo GERD symptoms after eradication of H. pylori, whereas 21 of 36 subjects experienced resolution of GERD symptoms after eradication of the infection. CONCLUSIONS: A substantial proportion of ulcer patients have symptoms and/or signs of coexisting GERD at initial presentation and this reduces the symptomatic benefit from H. pylori eradication. However, we have found no evidence that eradicating H. pylori induces de novo GERD symptoms in ulcer patients. 相似文献
