Abstract
Background/Aims There may be various factors that determine gastroesophageal reflux disease (GERD) as a result of hiatal hernia (HH) (such as the size of the hernia, age, other host and environmental factors) and the presence of protective factors to explain the absence of reflux disease should not be ignored. Helicobacter pylori (Hp) infection can prevent the development of GERD or cause it. This study aimed to determine whether Hp colonized in the stomach and hernia affects the development of erosive esophagitis (EE) in patients with HH. Materials and Methods In this case-controlled study, 111 patients with HH were eligible for the study. Study group with EE (n = 61, 55%) and control group without EE (n = 50, 45%) were formed. Groups were compared for gastric Hp and Hp in the hernia. Results While the frequency of Hp in the antrum was 55.7% in the group with EE, it was 30% in the control group (p = 0.01, OR: 2.94 in 95% CI 1.34-6.46). The rates in terms of HP frequency in the corpus were 43.6% and 32.1%, respectively, (p = 0.45). Hp colonization in HH was detected in 18 cases (29.50%) and 14 cases (28%), respectively, (p = 0.86). In regression analysis, antral Hp was found to be effective in the development of EE (p = 0.01). Conclusion As a result of this study, we think that antral Hp may have a causative role in the development of reflux esophagitis, but the presence of Hp in HH does not have an effective role in reflux esophagitis formation.

Impact of Helicobacter pylori Infection and Outcome of Anti- Helicobacter pylori Therapy in Patients with Reflux Laryngopharyngitis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8266321. [PMID: 35836834 PMCID: PMC9276480 DOI: 10.1155/2022/8266321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 06/08/2022] [Indexed: 11/18/2022]
Abstract
Objectives This study was designed to explore the relationship between Helicobacter pylori (Hp) infection and reflux laryngopharyngitis (RLP) and to evaluate the outcome of anti-Hp therapy in improving RLP symptoms. Methods A total of 410 patients with RLP were enrolled and tested for Hp infection. The association of Hp infection with reflux symptom index (RSI) and reflux finding score (RFS) was determined. Hp-positive patients received either a proton pump inhibitor (PPI) omeprazole alone (control group) or a combination regimen (experimental group) consisting of omeprazole, mosapride citrate, amoxicillin, and clarithromycin. Therapeutic outcomes were compared 4 weeks later. Results Of the 410 participants, 290 were Hp-positive and 120 Hp-negative. Both RSI and RFS were significantly higher in Hp-positive patients than in Hp-negative patients. Hp infection status was positively correlated with RSI (P < 0.05) and RFS (P < 0.05). The overall response rate was higher in the experimental group than in the control group. Both the groups had a significant reduction in RSI and RFS after therapy, with a greater improvement in the experimental group (P < 0.05). Conclusion Our findings establish a link between Hp infection and RLP. Anti-Hp therapy improves RSI and RFS in RLP patients. Therefore, Hp eradication drugs may be added to the PPI-based regimen in the treatment of RLP.

Abstract
BACKGROUND The association between H. pylori (Helicobacter pylori) infection and gastroesophageal reflux disease (GERD) is a complex and confusing subject. The aim of this study was to evaluate the association between helicobacter pylori infection and erosive gastroesophageal reflux disease. METHOD In a cross-sectional study, all patients referred for endoscopy due to dyspepsia were enrolled. The diagnosis of erosive GERD was made by endoscopy. Patients with normal esophagus were selected as comparison group. Random gastric biopsies were taken from all participants to diagnose H. pylori infection. RESULT In total, 1916 patients were included in this study, of whom 45.6% had GERD. The mean age (SD) was 42.95 (16.32). Overall, 1442 (75.3%) patients were positive for H. pylori infection. The frequency of H. pylori infection in mild GERD patients was higher than the severe GERD, but this difference was not significant (P = 0.214). Except for sociodemographic status (P < 0.001), other variables including gender, age, ethnicity, body mass index (BMI), smoking, and presence of hiatus hernia in patients had no significant association with the frequency of H. pylori infection. According to Robust Poisson regression models analysis, the association of H. pylori (PR 1.026; 95% CI 0.990-1.064; P = 0.158) and sociodemographic status were not significantly different between the two groups. But smoking, increased BMI, older age, presence of hiatus hernia, and peptic ulcer diseases were significantly associated with GERD compared with the non-GERD group. CONCLUSION In our results, there was no association between H. pylori infection and erosive GERD. Further studies are recommended.

Abstract
INTRODUCTION Whether the incidence of reflux esophagitis (RE) increases after the eradication of Helicobacter pylori (H. pylori) is controversial. Few reports have evaluated the presence or absence of RE after a long period of time, taking into account the degree of atrophy and/or administration of acid secretion inhibitors. We investigated the relationship between H. pylori and RE taking into account these factors. METHODS This was a retrospective cohort study with approval by the Ethics Committee. Patients who succeeded in H. pylori eradication treatment, and in whom there were images of the gastroesophageal junction on endoscopic examinations within 1 year before eradication treatment and more than 3 years after eradication were included. The degrees of RE and atrophy were retrospectively determined from the endoscopic images. The prevalence of RE before and after eradication and the incidence of newly developed RE after eradication between patients with or without atrophy improvement were compared using Fisher's exact test. RESULTS A total of 185 cases (male:female = 104:81; mean age, 63.5 years; mean observation period, 6.4 years) were examined. The prevalence of RE before and after eradication was 1.6% (3/185) and 7.0% (13/185), respectively (P = 0.019). RE was present in 8 (7.5%) of 106 cases with closed-type atrophy and in 5 (6.3%) of 79 cases with open-type atrophy after eradication (P = 0.75). Atrophy improved after eradication in 56 cases, of whom 4 (7.1%) had new onset of RE; the degree of atrophy did not improve in 126 cases, of whom 7 (5.4%) had new onset of RE (P = 0.74). There was no difference between the percentage of cases who took acid secretion inhibitors before and after eradication (P = 0.14). CONCLUSION The prevalence of RE increased a long time after eradication, even in patients who were taking an acid secretion inhibitor. The prevalence of RE was not related to the degree of atrophy or change in atrophy.

Abstract
BACKGROUND/AIMS This study evaluates the association between the eradication of Helicobacter pylori (H. pylori) and gastroesophageal reflux disease (GERD). MATERIALS AND METHODS Relevant studies were identified by conducting literature search in PubMed, Cochrane, Embase, CNKI, VANFUN, and VIP databases. The prevalence rates of gastroesophageal reflux, heartburn, epigastric pain, and nausea were extracted from the identified research articles and were used in meta-analysis of relative risks (RR) to achieve an overall effect size of the relationship between H. pylori eradication and GERD. RESULTS A total of 19 randomized controlled trials were included in this meta-analysis. The prevalence of gastroesophageal reflux was significantly higher in patients with H. pylori eradication compared with patients without it (RR: 1.54, 95% CI: 1.06-2.24; p=0.02). A subgroup analysis did not identify any significant difference in GERD prevalence in studies conducted outside China (RR: 1.62, 95% CI: 0.98-2.68) or in China (RR: 1.30, 95% CI: 0.76-2.22). There were no significant differences in heartburn (RR: 1.03, 95% CI: 0.88-1.20), epigastric pain (RR: 0.98, 95% CI: 0.13-7.56), or nausea (RR: 0.44, 95% CI: 0.07-2.72) risk between patients with and without H. pylori eradication. CONCLUSION Eradication of H. pylori infection is found to be associated with GERD, although regional differences may exist in the prevalence. Well-designed studies especially those with stratification of patients' basic conditions are needed to seek refined evidence of the association between H. pylori eradication and the GERD.

Abstract
BACKGROUND The role of Helicobacter pylori in the pathogenesis of reflux esophagitis is controversial. This study investigated the frequency of reflux esophagitis before and after H. pylori eradication in patients having endoscopic submucosal dissection for early gastric cancer. METHODS This study included 160 patients that fulfilled the study's criteria. Endoscopy was performed before and after H. pylori eradication, and reflux esophagitis was evaluated during the follow-up period. RESULTS Seropositivity for H. pylori in patients with early gastric cancer was 68.8%, 101 of them received eradication therapy. During the follow-up period, the incidence of reflux esophagitis increased from 3.1% to 18.8% in the successful eradication group but no case of reflux esophagitis was observed in the failed eradication group. The univariate and multivariate analyses showed a significant correlation between successful H. pylori eradication rate and the development of reflux esophagitis. CONCLUSIONS This study demonstrated that a successful H. pylori eradication therapy is a risk factor for newly developed reflux esophagitis in patients with endoscopic submucosal dissection for early gastric cancer.

Endoscopic Reflux Esophagitis and Reflux-Related Symptoms after Helicobacter pylori Eradication Therapy: Meta-Analysis. J Clin Med 2020; 9:jcm9093007.

Abstract
Backgrounds: The etiology of gastroesophageal reflux disease (GERD) including reflux esophagitis and non-erosive reflux disease is multifactorial and a recent meta-analysis showed no association between the development of GERD and Helicobacter pylori eradication in both Western and East-Asian populations. However, the problem remains that various inclusion criteria are used in these studies, which hinders meta-analysis. With a focus on reflux esophagitis with endoscopic mucosal injury, we meta-analysed to evaluate the association between eradication and reflux esophagitis and symptoms using a clearly defined set of inclusion criteria. Methods: We conducted a meta-analysis of studies published up until March 2020, which compared the incidence of reflux esophagitis and symptoms between patients undergoing H. pylori eradication therapy in a randomized placebo-controlled trial (Category A); between patients with successful and failed eradication (Category B); and between patients with successful vs. failed eradication, receipt of placebo, or no-treatment H. pylori-positives (Category C). Results: A total of 27 studies were included. Significant statistical effects were found for development of endoscopic reflux esophagitis [relative risk (RR): 1.46, 95% confidence interval (CI): 1.16-1.84, p = 0.01] or de novo reflux esophagitis (RR: 1.42, 95% CI: 1.01-2.00, p = 0.03) in the case group that received eradication in all studies, especially in Western populations. There was no significant difference in the incidence of symptoms after eradication between patient and control groups, regardless of category, location of population, or baseline disease. Conclusions: Eradication therapy for H pylori increases the risk of reflux esophagitis, irrespective of past history of esophagitis. In contrast, no effect was seen on reflux-related symptoms.

Abstract
BACKGROUND AND AIMS Eradication of Helicobacter pylori reduces the risk of gastric cancer. In this study, we investigated the risk beyond 10 years after eradication of H. pylori. METHODS We conducted a retrospective cohort study of 2737 patients who had yearly endoscopic follow-up after cure of H. pylori infection. For comparison of gastric cancer risk in the second decade of follow-up with that in the first decade, we calculated standardized incidence ratios (SIRs) by dividing the number of observed cases of gastric cancer in the second decade of follow-up by that of expected cases which was estimated using the incidence rate ratio of age in the first decade. RESULTS During the follow-up for as long as 21.4 years (mean 7.1 years), gastric cancer developed in 68 patients (0.35% per year). The SIRs for diffuse-type gastric cancer was infinity (0 expected case and 4 observed cases) in patients with mild gastric mucosal atrophy and 10.9 (95% confidence interval 4.53-26.1) with moderate atrophy, whereas no significant increase of SIRs was observed in intestinal-type cancer regardless of the grade of baseline gastric atrophy or in diffuse-type cancer in patients with severe atrophy even though who had the highest risk. CONCLUSIONS The longer the follow-up, the greater the risk of developing diffuse-type gastric cancer becomes in patients with mild-to-moderate gastric atrophy at baseline. Endoscopic surveillance should be continued beyond 10 years after cure of H. pylori irrespective of the severity of gastric atrophy.

Abstract
Background/aims: Interactions between Helicobacter pylori (Hp) and gastroesophageal reflux disease (GERD), which are common diseases worldwide, are confusing. In this study, the aim was to compare and evaluate the relationship between reflux esophagitis (RE) and Hp infection in adult patients with both the gastric localization of Hp and its histopathologic features.Materials and methods: 248 patients with RE were compared with 249 age and sex matched control groups. Biopsy specimens obtained from the gastric antrum and corpus were histologically evaluated.Findings: The incidence of Hp infection was significantly lower in patients with RE than in the control group (Ratio 1.53, 95% CI 1.07-2.20; p = .02, p < .05). Corpus Hp colonization and corpus gastritis scores were notably lower in the study group (p = .01, p < .05), whereas there was no significant difference in Hp colonization and antrum gastritis scores in the antrum. Corpus Hp colonization and gastritis scores were found to be negatively correlated with esophagitis development (r = -0.11; p = .01; (r = -0.14; p = .00 respectively, p < .05). There was no difference between the groups in terms of atrophy development (p > .05).Conclusion: This study showed that the presence of Hp infection in the corpus and corpus gastritis score was significantly lower in patients with erosive reflux esophagitis than in the control group. It also showed that Hp colonization and corpus gastritis scores were negatively correlated with esophagitis development. This inverse relationship was independent of atrophy.

Abstract
Interactions between Helicobacter Pylori (HP) and gastroesophageal reflux disease (GERD) are a complex issue. Several pathophysiological factors influence the development and the course of GERD, HP infection might be only one of these. Many studies emphasize the co-existence of these diseases. HP infection could contribute to GERD through both a protective and an aggressive role. Gastric acid secretion is a key factor in the pathophysiology of reflux esophagitis. Depending on the type of gastritis related to HP, acid secretion may either increase or decrease. Gastritis in corpus leads to hypoacidity, while antrum gastritis leads to hyperacidity. In cases of antral gastritis and duodenal ulcers which have hyperacidity, the expectation is an improvement in pre-existing reflux esophagitis after eradication of HP. In adults, HP infection is often associated with atrophic gastritis in the corpus. Atrophic gastritis may protect against GERD. Pangastritis which leads to gastric atrophy is commonly associated with CagA strains of HP and it causes more severe gastric inflammation. In case of HP-positive corpus gastritis in the stomach, pangastritis, and atrophic gastritis, reflux esophagitis occurs frequently after eradication of HP. Nonetheless, as a predisposing disease of gastric cancer, HP should be treated. In conclusion, as the determinative factors affecting GERD involving in HP, detailed data on the location of gastric inflammation and CagA positivity should be obtained by the studies at future.

Abstract
Some studies suggest that Helicobacter pylori (H. pylori) infection would be a protective factor for the gastroesophageal reflux. The aim of this study was to explore this fact. A group of 72 children, admitted in a pediatric gastroenterology regional center in Northeast Romania, diagnosed with gastroesophageal reflux by 24-hour continuous esophageal pH monitoring (results were interpreted using the Boix-Ochoa score), underwent upper endoscopy with gastric biopsy to detect the presence of H. pylori by the rapid urease testing and for bacteriological and histologic examination. 19 children (26.39%) had H. pylori infection, while 53 (73.61%) did not. The grade of esophagitis was classified according to the Los Angeles classification system. Out of 47 children with esophagitis A, 16 (34.04%) had H. pylori infection, while out of the 25 children with esophagitis B, only 3 (12%) had H. pylori infection, with statistic significance (χ2 = 54.69, P << 0.05, 95% confidence interval [CI]). Regarding the value of the Boix-Ochoa score, it appears that the presence of the H. pylori determines lower pH-metry scores (F = 8.13, P = 0.0015, 95% CI). The presence of the H. pylori was not an important factor in the gastroesophageal reflux. On the other hand its relationship with esophagitis appears to be inverse ratio. The fact that the H. pylori presence is statistically greater in the grade A esophagitis could confirm the hypothesis that the bacteria would slow down the development of the esophagitis.

Abstract
Background The Helicobacter pylori infection (HP) is related to the development of gastric lesions and lymphoma; however, it is not known if there is a relation with gastroesophageal reflux disease and reflux esophagitis. Aim To evaluate HP's relationship with esophagitis in patients undergoing upper endoscopy. Methods Observational, retrospective and cross-sectional study, being evaluated 9576 patients undergoing outpatient endoscopic examination during the period between January and December 2015. Were included patients with any esophageal alteration at the examination; greater than 18; of both genders; independent of the complaint or the reason for the examination, illness or drug use. Were excluded those with active bleeding during the examination and in use of anticoagulants. The variables gender, age, esophagitis and result of the urease test, were studied. For statistical analysis was used the Epi Info software 7.1.5.2. Results Most of the samples consisted of women and the overall average age was 46.54±16.32 years. The presence of infection was balanced for gender: 1204 (12.56%) women and 952 (13.92%) men. Relating degree of esophagitis HP- and HP+ was observed that the type A was the most common (58.79%, n=1460); 604 (24.32%) had grade B; 334 (13.45%) grade C, and 85 (3.42%) grade D. In the relation between the grade of esophagitis with gender, esophagitis A was predominant in women and present in 929 (63.33%), followed by type B, 282 (46.68%), 136 C (40.71%) and D 30 (35.29%). In men 531 (36.36%) showed type A, 322 (53.31%) B, 198 (59.28%) C, and 55 (64.70%) D. Among the groups 40-50 and over 60 years there was a significant difference in whether have or not have HP+. Conclusion There is no significant difference between HP infection and the different grades of esophagitis.

Abstract
Background: The influence of Helicobacter pylori (HP) in inflammatory disorders of the
digestive mucosa has been the subject of several studies since socioeconomic,
personal and environmental factors were implicated in the bacteria transmission.
Aim: To correlate the inflammatory endoscopic findings with HP infection and the onset
of mucosal diseases mucous of the upper digestive tract. Method: Comparative observational study, in which were collected data from 2247 patients
who underwent upper endoscopy and biopsies for HP with urease test. The patients
were divided into two groups: HP+ and HP- (control) in which endoscopic findings
were observed for the following changes: esophagitis, esophageal ulcer, gastritis,
erosive gastritis, gastric ulcer, bulboduodenitis, bulbar ulcer and without
disease. Results: As for esophagitis, there was little disparity in the distribution favorable to
HP+ group (HP+ =67.11% and HP- =69.89%) and esophageal ulcer (HP+ =0% and HP- =0,
21%). Gastritis was favorable to HP- group (HP+ =78.34% and HP- =73.63%), as well
as erosive gastritis (HP+ = 67,11% and HP- = 64,55%), in bulboduodenitis (HP+
=1,87% and HP- 1,23%), in gastric ulcer (HP+ =2,14% and HP- =2,03%) and in the
absence of alterations in the HP+ group (4.81%) with the HP- control group
(6,30%), in which there was little disproportion in favor of HP- group, but
without statistical significance. As for the bulbar ulcer (HP +=10.16% and HP-
=4.48%), there was statistically significant (p=0.00001). Conclusion: There is no difference between HP+ and HP- groups in inflammatory changes in
endoscopic gastroduodenal mucosa, except for the relationship between HP and
bulbar ulcer.

Abstract
BACKGROUND It is uncertain whether the Helicobacter pylori eradication therapy makes a role in the progression of gastroesophageal reflux disease (GERD). METHODS A meta-analysis was undertaken to investigate the effect of H pylori eradication therapy on the development of GERD. RESULTS Overall, 16 cohort studies were included. The authors demonstrated that H pylori eradication had no significant effect on the occurrence of GERD in these cohort studies (odds ratio = 0.87, 95% confidence interval = 0.66-1.14, I = 32.4%, P = 0.103). CONCLUSIONS In general, H pylori eradication has no significant effect on the development of GERD in the long term. However, eradication therapy should be taken once there is H pylori infection, because H pylori infection is acknowledged to be a major cause of acute and chronic gastritis and peptic ulcer diseases and has been established as a definite etiologic factor for gastric cancer.

Abstract
In the February 2013 Revision of Insured Medical Treatment, bacterial eradication for all Helicobacter pylori-positive individuals in Japan was covered under the insurance scheme. However, reflux esophagitis is believed to occur in approximately 10% of Japanese patients who undergo eradication therapy. Hence, the risk of reflux esophagitis among such cases should be carefully considered, particularly in the treatment for H. pylori-positive patients who are otherwise healthy. The eradication of H. pylori in cases of H. pylori-positive gastritis markedly suppresses gastric inflammation, and inhibits gastric mucosal atrophy and its progression to intestinal metaplasia. In a long-term follow-up study (10–20 years), eradication treatment was found to reduce the risk of subsequent gastric cancer. However, the fact that eradication-induced reflux esophagitis could increase the long-term risk of Barrett's esophagus and esophageal adenocarcinoma should also be considered in the Japanese population. Appropriate treatment with proton pump inhibitors should be taken into consideration for patients undergoing eradication therapy in clinical practice.

Abstract
BACKGROUND We previously reported that eradication of Helicobacter pylori in our cohort of patients with peptic ulcer disease reduced their risk of developing gastric cancer to approximately one-third after a mean follow-up period of 3.4 years (up to 8.6 years). We have now followed these patients for a longer period. METHODS A total of 1,222 consecutive patients with peptic ulcer diseases who completed more than 1-year follow-up after receiving H. pylori eradication therapy were followed with annual endoscopic surveillance for a mean of 9.9 years (as long as 17.4 years). RESULTS H. pylori infection was judged cured in 1,030 patients (eradication-success group) but persisted in 192 (eradication-failure group) after initial eradication therapy. In the eradication-failure group, 114 patients received re-treatment at a mean of 4.4 years after the start of follow-up, and 105 of these were cured of infection. Gastric cancer developed in 21 of the 1,030 patients in the eradication-success group and in nine of the 192 in the failure group (p = 0.04). The risk of developing gastric cancer in the eradication-success group (0.21 %/year) was significantly lower than that in the failure group (0.45 %, p = 0.049). The longest interval between the initial H. pylori eradication and the occurrence of gastric cancer was 14.5 years in the eradication-success group and 13.7 years in the eradication-failure group. CONCLUSIONS A prophylactic effect for gastric cancer persists for more than 10 years after H. pylori eradication therapy, but we should be aware that cancer can develop even after that interval.

Abstract
The aim of this study was to investigate the effect of Helicobacter pylori (H. pylori) infection on the lower esophageal microbiota and the eradication of H. pylori through the use of antibiotics. Forty-five BALB/C mice were randomly divided into negative control, infection and treatment groups. The mice were sacrificed and DNA was extracted from the lower esophageal microbiota. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was performed to determine the composition of the microbiota. Quantity One® 1-D Analysis Software was used for the analysis of the DGGE profiles. The different bands from the groups were amplified with 16S rDNA V6 region primers. DNA sequencing and Basic Local Alignment Search Tool analysis were performed for the identification of the bands. H. pylori colonization led to severe ulcers in the stomachs of the mice, and these ulcers were alleviated by antibiotic treatment. The infection group had an increased number of bacterial species in the stomach compared with the control and treatment groups. DGGE fingerprinting of the lower esophagus showed that there were significant differences in the number of bands (P<0.05), diversity index and abundance among the groups (P<0.05); however, no significant differences in homogeneity were observed (P>0.05). Although the composition of flora species in the lower espohagus varied, the dominant species, and their relative contents, were similar in the control, infection and treatment groups. The present study provided a microecological basis for the understanding of the pathogenesis of lower esophageal diseases, following the eradication of H. pylori infection with antibiotics.

Abstract
Background The nature of the relationship between Helicobacter pylori and reflux esophagitis (RE) is not fully understood. In addition, the effect of H. pylori eradication on RE and gastroesophageal reflux disease (GERD) is unclear. This study was designed to investigate the relationship between H. pylori infection and the grade of GERD in patients with reflux symptoms. Methods Between January 2010 and July 2013, 184 consecutive patients with daily reflux symptoms for at least one year were evaluated at the ambulatory for functional esophageal disease, Tor Vergata University Hospital, Rome, Italy. All patients underwent a pretreatment evaluation, which included anamnesis, clinical examination, Esophagogastroduodenoscopy (EGDS) with biopsy, esophageal manometry and 24-hour pH-metry. All statistical elaborations were obtained using Statigraphies 5 plus for Window XP. Results There was no statistical difference regarding Lower Esophageal Sphincter (LES) pressure between patients who were H. pylori-positive and H. Pylori-negative (19.2 ± 9.5 (range: 3.7 to 46.2) and 19.7 ± 11.0 (range: 2.6 to 61), respectively). Further, no significant difference was evidenced in esophageal wave length (mean value: 3.1 seconds in H. pylori-negative patients versus 3.2 seconds in H. pylori-positive patients) or in esophageal wave height (mean value: 72.2 ± 39.3 in H. pylori-negative patients versus 67.7 ± 28.4 in H. pylori-positive patients). We observed that hiatal hernia (P = 0.01), LES opening (P = 0.05), esophageal wave length (P = 0.01) and pathological reflux number (P = 0.05) were significantly related to the presence of esophagitis. However, H. pylori infection was not significantly related to the presence of reflux esophagitis. Conclusions Our clinical, endoscopic, manometric and pH-metric data shows no significant role of H. pylori infection in the development of GERD or in the pathogenesis of reflux esophagitis. However, current data do not provide sufficient evidence to define this relationship and further prospective large studies are needed.

Abstract
Korea and Japan show the highest incidence of gastric cancer and Helicobacter pylori infection. New 2013 guidelines on H. pylori infection differ between the two countries with regard to the indications for H. pylori eradication, diagnostic methods, and treatment regimens. Indications for eradication in Korean guideline focus on specific diseases such as peptic ulcer disease, low-grade gastric mucosa-associated lymphoid tissue lymphoma, and after resection of early gastric cancer, while Japanese guideline includes all H. pylori-associated gastritis for the prevention of dissemination. With regard to the diagnosis, either noninvasive or invasive method (except for bacterial culture) is recommended in Korea, while two noninvasive tests including serum anti-H. pylori IgG antibody level are preferred in Japan. As for the treatment regimens, second-line treatment (quadruple bismuth-containing regimen) is recommended without first-line triple therapy in areas of high clarithromycin resistance in Korea. However, there is no bismuth-based second-line treatment in Japan, and the Japanese regimen consists of a lower dose of antibiotics for a shorter duration (7 days). Such discrepancies between the two countries are based not only on the differences in the literature search and interpretation, but also on the different approvals granted by the national health insurance system, manufacturing process of the antibiotics, and diagnostic techniques in each country. Collaborations are required to minimize the discrepancies between the two countries based on cost-effectiveness.

Abstract
New 2013 guidelines on Helicobacter pylori (H. pylori) infection have been published in China, Japan, and South Korea. Like the previous ones, these new guidelines differ between the three countries with regard to the indications for H. pylori eradication, diagnostic methods, and treatment regimens. The most profound change among all of the guidelines is that the Japanese national health insurance system now covers the expenses for all infected subjects up to second-line treatment. This makes the Japanese indications for eradication much wider than those in China and South Korea. With regard to the diagnosis, a serum H. pylori antibody test is not recommended in China, whereas it is considered to be the most reliable method in Japan. A decrease relative to the initial antibody titer of more than 50% after 6-12 mo is considered to be the most accurate method for determining successful eradication in Japan. In contrast, only the urea breath test is recommended after eradication in China, while either noninvasive or invasive methods (except the bacterial culture) are recommended in South Korea. Due to the increased rate of antibiotics resistance, first-line treatment is omitted in China and South Korea in cases of clarithromycin resistance. Notably, the Japanese regimen consists of a lower dose of antibiotics for a shorter duration (7 d) than in the other countries. There is neither 14 d nor bismuth-based regimen in the first-line and second-line treatment in Japan. Such differences among countries might be due to differences in the approvals granted by the governments and national health insurance system in each country. Further studies are required to achieve the best results in the diagnosis and treatment of H. pylori infection based on cost-effectiveness in East Asian countries.

Reinfection rate of Helicobacter pylori after eradication treatment: a long-term prospective study in Japan. J Gastroenterol 2012; 47:641-6. [PMID: 22350696 DOI: 10.1007/s00535-012-0536-9] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2011] [Accepted: 12/26/2011] [Indexed: 02/04/2023]
Abstract
BACKGROUND We previously reported that the reinfection rate with Helicobacter pylori in Japan was low despite a high prevalence of infection. In the present study, we extended our previous work to more accurately determine the reinfection rate. METHODS We enrolled 1625 patients (219 women and 1406 men, mean age 50.8 years) who had received H. pylori eradication therapy. After documentation of eradication, bacterial culture and urea breath test were carried out yearly. H. pylori strains were analyzed by using random amplification of polymorphic DNA fingerprinting. RESULTS A total of 1609 patients were followed for up to 12.5 years (mean 4.7 years); H. pylori became re-positive in 26 patients. In 13 of the 26 patients, H. pylori became positive at the first-year follow up. Stored H. pylori isolates were available for analysis from ten of the 13 patients; four of the isolates were genetically different from the initial strain, but the other six were identical to the initial strain. In the other 13 patients, H. pylori became positive at later follow up (mean 4.8 years; range 1.8-8.0 years). In all of the four of these patients whose isolates could be analyzed, the H. pylori strains were different from the initial strain. Assuming that reinfection occurred in the four patients positive for different strains of H. pylori at the first-year follow up and in the 13 positive at later follow up, the reinfection rate was 0.22% per year. CONCLUSIONS When probable recrudescence (H. pylori positivity with identical strains) was excluded, the reinfection rate of H. pylori in this Japanese population was very low, but we note that reinfection can occur over many years.

Abstract
Background/Aims A two-year, prospective, nationwide multicenter study was undertaken to evaluate the effect of Helicobacter pylori eradication on the development of reflux esophagitis (RE) and gastroesophageal reflux disease (GERD) symptoms in the Korean population. Methods In total, 1,489 subjects without RE were enrolled at the outpatient clinics of 12 tertiary hospitals nationwide, and 452 subjects underwent follow-up (F/U) for 2 years to evaluate the development of RE and GERD symptoms. Results RE was found
in 33 subjects (7.3% of 452 subjects) and 14 subjects (7.3% of 192 subjects) during the first and second year of F/U, respectively. H. pylori status was not associated with the development of RE. RE was found in six (9.0%) of 67 H. pylori-negative patients, in 26 (11.2%) of 233 eradicated subjects and in eight (7.0%) of 114 noneradicated subjects (p=0.532). Multivariate analysis showed that age ≥60 years (odds ratio [OR], 7.11; 95% confidence interval [CI], 1.92 to 26.41), alcohol consumption (OR, 4.43; 95% CI, 1.03 to 19.19) and F/U cholesterol levels ≥200 mg/dL (OR, 5.03; 95% CI, 1.32 to 19.17) were significant risk factors for the development of RE. There was no significant difference in the development of GERD symptoms or weight according to H. pylori status during the 2-year F/U. Conclusions Eradication of H. pylori did not affect the development of reflux esophagitis or GERD symptoms among patients in outpatient gastroenterology clinics in South Korea.

Abstract
A 75-year-old man underwent endoscopic hemostatic therapy for hemorrhagic gastric ulcer in September 2002. After healing of the gastric ulcer, he underwent Helicobacter pylori eradication therapy in February 2003. In August 2007, an irregular tumor was detected in the lower esophagus at annual checkup for gastric cancer screening using X-ray. Endoscopic examination showed that the lower margin of the tumor almost coincided with the esophagogastric junction and that a short segment of Barrett's epithelium existed near the tumor. Biopsies of the tumor showed moderately to poorly differentiated adenocarcinoma. Mild reflux esophagitis and minor hiatal hernia was also observed, and the previously treated gastric ulcer was not recurrent. Absence of H. pylori was confirmed by serum antibody and urea breath test. Surgical resection of the lower esophagus and proximal stomach was performed. The tumor invaded into the muscularis propria of the esophageal wall but had no evidence of lymph node metastasis. Based on macroscopic and pathological findings, the tumor was recognized as esophageal adenocarcinoma. Previous endoscopic examination did not detect any apparent signs of tumor in the esophagogastric junction. As far as we know, this is the first report documenting a newly developed esophageal adenocarcinoma after the successful eradication of H. pylori.

Abstract
The speculations on the protective role of Helicobacter pylori against gastroesophageal reflux disease (GERD) originated from epidemiological observations. These studies have shown that the rising trend of GERD is coincident with declining prevalence of H. pylori and peptic ulcer disease in Asia. Furthermore, most case-control and population-based studies suggest a negative association between H. pylori infection and GERD. It is generally believed that the preponderance of cagA+ and vacA+ virulent strains and proinflammatory interleukin-1 beta polymorphism increase the risk of hypochlohydria and protects against the development of GERD in Asian population. Recovery of gastric acid secretion and emergence of reflux esophagitis has been reported after H. pylori eradication in patients with corpus gastritis and atrophic gastritis. Recent studies have also reported that H. pylori eradication leads to recovery of ghrelin secreting cells in the gastric corpus and a rise in plasma ghrelin levels, which may contribute to obesity through its appetite-stimulating action and predispose to GERD. The prevalence of H. pylori infection is generally lower in younger Asians who enjoy improved socioeconomic status and sanitation compared with their older counterparts. The Asian population is probably facing a rising generation with high gastric acid and ghrelin secretion rates. These physiological changes may contribute to increased dietary calorie intake, obesity and increased prevalence of GERD.

Abstract
BACKGROUND We previously reported that eradication of Helicobacter pylori reduced the risk of developing gastric cancer in patients with peptic ulcer diseases. In the present study, we further followed up our patient group to investigate the occurrence and clinical features of gastric cancers that developed after cure of the infection. METHODS Prospective post-eradication evaluations were conducted on 1674 consecutive patients who had received successful H. pylori eradication therapy. The patients had undergone endoscopic examination before eradication therapy to evaluate peptic ulcers, background gastric mucosal atrophy, and H. pylori infection. After confirmation of cure of the infection, follow-up endoscopy was performed yearly. RESULTS The patients were followed for up to 14.1 years (a mean of 5.6 years). During the follow-up, gastric cancer developed in 28 of the 1674 patients as long as 13.7 years after the cure of H. pylori infection. The risk of developing gastric cancer was 0.30% per year. Histologically, 16 of the gastric cancers were the intestinal type and 12 were the diffuse type; the risk of each cancer type was 0.17 and 0.13% per year, respectively. There was no significant inflammatory cell infiltration in the background gastric mucosa at the time the cancers were recognized. CONCLUSION There is a risk of developing gastric cancer of both the intestinal and diffuse types even after the cure of H. pylori infection and extinction of gastric inflammation. It is important to inform patients about the risk of gastric cancer after eradication therapy and offer them surveillance endoscopy.

Abstract
OBJECTIVES We evaluated the association between current Helicobacter pylori infection and reflux esophagitis and the effect of H. pylori eradication on reflux esophagitis in a healthy screening population. METHODS A total of 10,102 subjects in a comprehensive screening cohort were enrolled, and 4,007 subjects had follow-up after a median of 2 years. Effects of H. pylori infection on reflux esophagitis were estimated with odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression analysis. We evaluated the change in prevalence of reflux esophagitis and reflux symptoms after H. pylori eradication vs. persistence. RESULTS The prevalence of reflux esophagitis (as classified by the Los Angeles system) was 4.9% (490/10,102). Whereas the prevalence of reflux esophagitis was 6.4% (319/4,971) in subjects without H. pylori infection, it was 3.3% (171/5,131) in subjects with infection (P<0.001). H. pylori infection had a strong negative association with reflux esophagitis in multivariate analysis (OR 0.42; 95% CI, 0.34-0.51). Compared with the prevalence of reflux esophagitis in the persistent infection group, the prevalence of reflux esophagitis increased after successful H. pylori eradication (OR 2.34; 95% CI, 1.45-3.76; P<0.001), which was comparable to that of the H. pylori-negative group (OR 2.42; 95% CI, 1.73-3.36; P<0.001). However, reflux symptoms had no association with H. pylori infection or eradication. CONCLUSIONS In a healthy screening population, H. pylori infection had a strong negative association with reflux esophagitis, but H. pylori eradication increased the prevalence of erosive esophagitis to the level of H. pylori-negative individuals. Long-term clinical significance of newly developed erosive esophagitis after H. pylori eradication should be evaluated prospectively.

Abstract
Several interesting studies have been published on nonmalignant Helicobacter pylori-related conditions over the past year, which are reviewed in this article. A revival of interest in the histologic classification of gastritis has led to grading of gastritis into stages correlating with risk of neoplastic progression, new data to improve this concept have been published. Unselected prescription of proton-pump inhibitors in patients with dyspepsia has been questioned by the finding that withdrawal of proton-pump inhibitors induces acid-related symptoms in healthy volunteers, probably by the mechanism of rebound gastric acid hypersecretion. Additional data on the rationale of tapering proton-pump inhibitor therapy are therefore awaited. Moreover, new data on peptic ulcer disease and its complications provide clear recommendations for daily clinical practice. Testing and eradication of H. pylori in patients with peptic ulcer bleeding is essential. However, in H. pylori-negative peptic ulcer disease, high overall patient mortality should be acknowledged, and this should guide considering continuation of nonsteroidal anti-inflammatory drugs. The role of H. pylori in the pathogenesis of gastroesophageal reflux disease is still unclear. An association has been described by several studies; however, it cannot be translated to individual risks for development of gastroesophageal reflux disease after H. pylori eradication. Possibly, additional data on subgroups, such as gastric ulcer, duodenal ulcer patients, and associated gastric mucosal changes, will solve this issue.

J Gastroenterol 2009; 44:819-25.

Abstract
PURPOSE The measurement of serum pepsinogens is clinically useful to represent gastric acid secretion. Since both serum pepsinogens and gastric acid secretion are considerably altered by H. pylori eradication, the correlation between these two parameters could be different prior to and after eradication. In this study, we investigated the correlation between the two parameters prior to and after eradication. METHODS One hundred eighteen H. pylori-positive patients with peptic ulcers or chronic gastritis were enrolled in this retrospective analysis. In all participants both the measurement of serum pepsinogens and the determination of gastric acid secretion were performed prior to and at 1 month after successful eradication. In 85 subjects, the same assessments were repeated at 7 months. Correlations between serum pepsinogens and gastric acid secretion were assessed using linear regression analysis. RESULTS The pepsinogen I/II ratio (r = 0.56) was a better indicator of gastric acid secretion in H. pylori-infected subjects than pepsinogen I itself (r = 0.31). Eradication of H. pylori altered the association, causing pepsinogen I (r = 0.55) to become a better indicator of gastric acid secretion compared with the pepsinogen I/II ratio (r = 0.40) at 1 month after eradication, followed by similar tendencies at 7 months. CONCLUSION Using different serum biomarkers (pepsinogen I/II ratio prior to eradication or pepsinogen I after eradication), the measurement of serum pepsinogens is useful for predicting the individual gastric acid secretion level not only in H. pylori-infected subjects, but also in subjects with histories of eradication of the infection.
