Comparisons of pathologic findings and outcomes of gastric cancer patients younger and older than 40: a propensity score matching study in a single center of Korea. JGH Open 2023; 7:118-127. [PMID: 36852144 PMCID: PMC9958344 DOI: 10.1002/jgh3.12860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 10/18/2022] [Accepted: 01/01/2023] [Indexed: 01/17/2023]
Abstract
Background and Aim Gastric cancer (GC) is one of the most common cancers worldwide, with a high incidence rate in Korean men. However, comparative studies are scarce on the pathologic findings and treatment effects of GC in patients aged less than 40 years. We evaluated the characteristics and pathologic findings of GC patients aged younger and older than 40 years. Methods We retrospectively analyzed 2307 patients diagnosed with GC between January 2010 and May 2018. Eighty-eight (3.8%) and 2219 (96.2%) patients were younger and older than 40 years, respectively. The patients were divided into younger (n = 70) and older (n = 62) age groups through propensity matching. Results Overall, compared to the younger group, the older group (n = 2219) had a significantly higher proportion of male patients (66.7% vs 39.8%; P < 0.001) and patients who underwent endoscopic submucosal dissection (ESD) (2.3% vs 23.1%; P < 0.001). However, young patients more often underwent operations compared to older patients (78.4% vs 60.1%; P = 0.001). In the propensity-matched group, older patients more often showed differentiated carcinoma, including well-differentiated (5.7% vs 11.3%) and moderately differentiated (1.4% vs 32.3%). However, younger patients more often showed signet ring cell carcinoma (SRC) (70.0% vs 25.8%). In multivariate analysis, Helicobacter pylori infection (odds ratio, 12.643; 95% confidence interval, 1.068-1449.665; P = 0.044) independently correlated with SRC risk. Conclusions Patients below 40 years were more likely to undergo surgery compared to ESD, and pathologic findings were more common in SRC. Therefore, more active screening and H. pylori eradication are needed even in patients aged less than 40 years.

THE KOREAN JOURNAL OF GASTROENTEROLOGY = TAEHAN SOHWAGI HAKHOE CHI 2022; 80:28-33. [PMID: 35879060 DOI: 10.4166/kjg.2022.036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 06/21/2022] [Accepted: 06/22/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND/AIMS Symptom-based subtyping of functional dyspepsia (FD) is used to segregate patients into groups with homogenous pathophysiological mechanisms. This study examined whether subtyping could reflect the duodenal and gastric microinflammation in FD patients. METHODS Twenty-one FD patients without Helicobacter pylori infection were recruited. An endoscopic biopsy was performed in the duodenum 2nd portion, stomach antrum, and body. The eosinophil and mast cell counts per high-power field (×40) were investigated by H&E and c-kit staining, respectively. The degree of inflammatory cell infiltration, atrophy, and intestinal metaplasia was also determined by H&E staining in the stomach. The baseline characteristics and eosinophil and mast cell infiltrations were compared among the three groups (epigastric pain syndrome, postprandial distress syndrome, and overlap). RESULTS According to the symptom assessment, seven subjects were classified into the epigastric pain syndrome group, 10 into the postprandial syndrome group, and four into the overlap group. The baseline variables were similar in the three groups. Eosinophil infiltration was more prominent in the duodenum than in the stomach. In contrast, mast cell infiltration was similar in the duodenum and stomach. The eosinophil counts in the duodenum were similar in the three groups. The eosinophil counts in the stomach and mast cell counts in the duodenum and stomach were also similar in the three groups. CONCLUSIONS Duodenal eosinophil infiltration was prominent in FD patients, but the eosinophil counts were similar regardless of the symptom-based subtypes of FD. Hence, the current symptom-based subtyping of FD does not reflect duodenal eosinophil and mast cell infiltration.

Randomized Controlled Trial Comparing the Efficacy of Sustained-Release Formula of Mosapride-Plus-Esomeprazole Combination Therapy to Esomeprazole Monotherapy in Patients with Gastroesophageal Reflux Disease. J Clin Med 2022; 11:jcm11071965. [PMID: 35407572 PMCID: PMC8999938 DOI: 10.3390/jcm11071965] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 03/26/2022] [Accepted: 03/30/2022] [Indexed: 12/12/2022] Open
Abstract
We aimed to evaluate whether adding a sustained-release (SR) formula of mosapride to proton-pump inhibitors (PPIs) would be more effective in controlling symptoms than PPI alone in patients with gastroesophageal reflux disease (GERD). Sixty patients with heartburn and/or regurgitation were randomly assigned to two groups: mosapride SR 15 mg combined with esomeprazole 20 mg once daily (ME group) and esomeprazole 20 mg once daily alone (E group). The primary endpoint was the complete-resolution rate of GERD symptoms after eight-week medication, and the secondary endpoints were the complete-resolution rate of GERD symptoms after four-week medication, symptom-improvement rates ≥ 50% after four- and eight-week medication, and change in reflux-disease-questionnaire (RDQ) and GERD-health-related quality-of-life (GERD-HRQL) scores from baseline at four- and eight-week medication. No significant differences in complete-symptom-resolution rates at eight weeks and four weeks or in the changes in RDQ and GERD-HRQL scores from baseline at four- and eight-week medication were observed between the ME and E groups. The symptom-improvement rate of ≥50% after four and eight weeks was comparable between both groups. Adding mosapride SR to esomeprazole in patients with GERD provides no additional benefits in controlling GERD symptoms.

Abstract
Background/Aims Esophageal motility disorders (EMDs) contribute to the pathophysiology of gastroesophageal reflux disease. However, the causes of EMDs and their impact on gastroesophageal reflux disease-associated symptoms remain unknown. This study aims to elucidate clinical features associated with various types of EMDs in patients with heartburn symptoms. Methods Of the 511 patients who underwent high-resolution manometry, 394 who were evaluated for heartburn symptoms were examined. Patients subjected to high-resolution manometry were classified into 4 groups outflow obstruction group, hypermotility group, hypomotility group, and normal motility group. Symptoms were evaluated using 3 questionnaires. Patient characteristics and symptoms for each EMD type were compared with those of the normal motility group. Results Of the 394 patients, 193 (48.9%) were diagnosed with EMDs, including 71 with outflow obstruction, 15 with hypermotility, and 107 with hypomotility. The mean dysphagia score was significantly higher in each of the 3 EMD groups compared with those with normal motility. The mean acid reflux and dyspepsia scores were significantly lower in the outflow obstruction group (P < 0.05). The mean body mass index and median Brinkman index were significantly higher in the hypermotility group (P = 0.001 and P = 0.018, respectively), whereas the mean diarrhea and constipation scores were significantly lower in the hypomotility group (P < 0.05). Conclusions The results of our study indicate that different EMDs have distinct characteristics. Cigarette smoking and high body mass index were associated with esophageal hypermotility. Assessment of the dysphagia symptom scores may help identify patients with EMDs.

Gastritis: The clinico-pathological spectrum. Dig Liver Dis 2021; 53:1237-1246.

Abstract
The inflammatory spectrum of gastric diseases includes different clinico-pathological entities, the etiology of which was recently established in the international Kyoto classification. A diagnosis of gastritis combines the information resulting form the gross examination (endoscopy) and histology (microscopy). It is important to consider the anatomical/functional heterogeneity of the gastric mucosa when obtaining representative mucosal biopsy samples. Gastritis includes self-limiting and non-self-limiting (long-standing) inflammatory diseases, and the latter are epidemiologically, biologically and clinically linked to the onset of gastric cancer (i.e. "inflammation-associated cancer"). Different biological models of inflammation-associated gastric oncogenesis have been proposed. Helicobacter pylori (H. pylori) gastritis is the most prevalent worldwide, and H. pylori is classified as a first-class carcinogen. On these bases, eradicating H. pylori is mandatory for the primary prevention of gastric cancer. Non-self-limiting gastritis may also be triggered by the immune-mediated destruction of gastric parietal cells, resulting in autoimmune gastritis. In both H. pylori-related and autoimmune gastritis, the non-self-limiting inflammation results in atrophy of the gastric mucosa, which is the main factor promoting gastric cancer. Long-term follow-up studies consistently demonstrate the prognostic impact of the histological staging of gastritis in gastric cancer secondary prevention strategies.

Abstract
Background/Aims A diagnosis of gastroesophageal reflux disease is challenging in patients who have reflux symptoms but do not respond to proton pump inhibitors nor have reflux esophagitis and hiatal hernia (HH) on endoscopy. This study examined the predictive role of the endoscopic findings, including the flap valve grade for pathologic acid exposure (PAE) to establish an endoscopic prediction model in patients with neither reflux esophagitis nor HH. Methods Five hundred seventy-eight patients who underwent upper endoscopy and 24 hours pH monitoring for reflux esophageal symptoms without evidence of reflux esophagitis and HH were analyzed. The gastroesophageal flap valve (GEFV), esophageal metaplasia, and chronic atrophic gastritis were assessed. The association between the endoscopic parameters and PAE was evaluated. Results Four hundred ninety-four patients were enrolled. The most common complaint was chest discomfort (42.3%) followed by globus (31.8%), dysphagia (7.9%), and heartburn (7.7%). PAE was present in 43 patients (8.7%). Multivariable analysis revealed PAE to be associated with the GEFV grade (p<0.001) and inversely associated with the chronic atrophic gastritis grade (p=0.005). Using these features, a predictive model was established and showed an area under the receiver operating characteristic curve of 0.705 (95% CI 0.619-0.790). The cutoff value of 12.0 had a sensitivity and specificity of 44.0% and 84.0%, respectively. Conclusions A loosened GEFV is associated with a risk of PAE in patients with neither reflux esophagitis nor HH, while atrophic gastritis is preventive. On the other hand, the endoscopic predictive model revealed a low sensitivity for detecting PAE. Thus, reflux testing needs to be performed further when gastroesophageal reflux disease is suspected, even without endoscopic evidence.

Abstract
Reflux esophagitis is known to be more prevalent in males, and previous studies have suggested sex differences in its risk factors. However, little is known about sex differences in the time-course of risk factors before reflux esophagitis onset. Thus, we conducted a retrospective longitudinal study using health checkup records. From the records of 230,056 individuals obtained from nine institutes in Japan, we selected 1,558 male reflux esophagitis cases, 3,116 male controls, 508 female reflux esophagitis cases, and 1,016 female controls were selected. We compared time-courses of risk factors between the case and control groups and identified abdominal circumference (AC), diastolic blood pressure, alanine transaminase (ALT), and current smoking in males and body mass index (BMI) in females as sex-specific risk factors. We also found that AC and ALT in males and BMI in females were significantly different between the reflux esophagitis case and control groups during the five years before reflux esophagitis onset. Our results suggest that visceral fat-type obesity and fatty liver in males and higher BMI in females are more frequently observed in reflux esophagitis cases several years before reflux esophagitis onset, and that proactive intervention to lifestyle can help prevent reflux esophagitis in both males and females.

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.

Predictive Significance of Promoter DNA Methylation of Cysteine Dioxygenase Type 1 (CDO1) in Metachronous Gastric Cancer. J Gastric Cancer 2021; 21:379-391.

Abstract
Purpose Promoter DNA methylation of various genes has been associated with metachronous gastric cancer (MGC). The cancer-specific methylation gene, cysteine dioxygenase type 1 (CDO1), has been implicated in the occurrence of residual gastric cancer. We evaluated whether DNA methylation of CDO1 could be a predictive biomarker of MGC using specimens of MGC developing on scars after endoscopic submucosal dissection (ESD). Materials and Methods CDO1 methylation values (TaqMeth values) were compared between 33 patients with early gastric cancer (EGC) with no confirmed metachronous lesions at >3 years after ESD (non-MGC: nMGC group) and 11 patients with MGC developing on scars after ESD (MGCSE groups: EGC at the first ESD [MGCSE-1 group], EGC at the second ESD for treating MGC developing on scars after ESD [MGCSE-2 group]). Each EGC specimen was measured at five locations (at tumor [T] and the 4-point tumor-adjacent noncancerous mucosa [TAM]). Results In the nMGC group, the TaqMeth values for T were significantly higher than that for TAM (P=0.0006). In the MGCSE groups, TAM (MGCSE-1) exhibited significantly higher TaqMeth values than TAM (nMGC) (P<0.0001) and TAM (MGCSE-2) (P=0.0041), suggesting that TAM (MGCSE-1) exhibited CDO1 hypermethylation similar to T (P=0.3638). The area under the curve for discriminating the highest TaqMeth value of TAM (MGCSE-1) from that of TAM (nMGC) was 0.81, and using the cut-off value of 43.4, CDO1 hypermethylation effectively enriched the MGCSE groups (P<0.0001). Conclusions CDO1 hypermethylation has been implicated in the occurrence of MGC, suggesting its potential as a promising MGC predictor.

Abstract
Purpose While the incidence of Barrett’s neoplasia has been increasing in Western countries, the disease remains rare in Asian countries. Therefore, very few studies have investigated the endoscopic treatment for Barrett’s neoplasia in Korea. Endoscopic submucosal dissection (ESD) enables en bloc and complete resection of gastrointestinal neoplastic lesions. This study aimed to evaluate the therapeutic outcomes of ESD for Barrett’s neoplasia in a single center in Korea and to examine the predictive factors for incomplete resection. Materials and Methods We conducted a retrospective observational study of 18 patients who underwent ESD for superficial Barrett’s neoplasia (dysplasia and early cancer) between January 2010 and December 2019 at Pusan National University Hospital. The therapeutic outcomes of ESD and procedure-related complications were analyzed. Results En bloc resection, complete resection, and curative resection were performed in 94%, 72%, and 61% of patients, respectively. Histopathology (submucosal or deeper invasion of the tumor) was a significant predictive factor for incomplete resection (P=0.047). Procedure-related bleeding and stenosis were not observed, whereas perforation occurred in one case. During the median follow-up period of 12 months (range, 6–74 months), local recurrence occurred in 2 patients with incomplete resection, one patient underwent repeat ESD, and the other patient received concurrent chemoradiotherapy. The 3-year overall and disease-specific survival rates were 73% and 93%, respectively. Conclusions ESD seems to be an effective and safe treatment for superficial Barrett’s neoplasia in Korea. Nevertheless, the suitability of ESD for Barrett’s cancer cases should be determined considering the high risk of deep submucosal invasion.

Narrowband imaging with near-focus magnification for discriminating the gastric tumor margin before endoscopic resection: A prospective randomized multicenter trial.

Abstract
BACKGROUND AND AIM This study investigated the usefulness of near-focus narrowband imaging (NF-NBI) for determining gastric tumor margins compared with indigo carmine chromoendoscopy (ICC) before endoscopic submucosal dissection (ESD). METHODS This prospective randomized controlled trial was conducted at seven teaching hospitals in Korea. Patients with gastric adenoma or differentiated adenocarcinoma undergoing ESD were enrolled and randomly assigned to the NF-NBI or ICC group. A marking dot was placed on the most proximal margin of the tumor before ESD. The primary endpoint was delineation accuracy, which was defined as presence of marking dots within 1 mm of the tumor margin under microscopic observation. RESULTS A total of 200 patients in the NF-NBI group and 195 patients in the ICC group were included. The delineation accuracy rate was 84.5% in the NF-NBI group and 81.0% in the ICC group (P = 0.44). However, the distance from the marking dot to the margin of the tumor was significantly shorter in the NF-NBI group than in the ICC group (0.8 ± 0.8 vs 1.2 ± 1.3 mm, P < 0.01). Even after adjustment of other clinicopathological factors that are associated with difficulty of tumor delineation, NF-NBI did not show significant association with accurate delineation (odds ratio of 0.86, P = 0.60). CONCLUSIONS This prospective multicenter study showed that NF-NBI is not superior to ICC in terms of accurately delineating gastric tumors (NCT02661945).

Abstract
Background Previous reports indicate that the methylenetetrahydrofolate reductase (MTHFR) 677C > T polymorphism plays a role in gastric cancer. However, whether it influences the development and progression of atrophic gastritis remains ambiguous. We aimed to determine the possible relationship between MTHFR C677T polymorphism and the severity of atrophic gastritis. Methods A total of 128 patients without Helicobacter pylori infection were included in the study. The severity of gastric atrophy was assessed by pathological diagnosis using OLGA and OLGIM Gastritis Staging System. MTHFR 677C > T genotyping was performed by digital fluorescence molecular hybridization. Categorical variables were analyzed by percentages using the χ2 test. Results In this study, the TT genotype was significantly more frequent among Helicobacter pylori-negative patients aged ≤44 years (age ≤ 44 years vs. > 44 years, P = 0.039). Patients with TT genotype showed a higher ratio of incisura with atrophy or intestinal metaplasia (TT vs. CC + CT, P = 0.02). Furthermore, TT genotype was associated with more severe lesions compared with the CC + CT genotypes (TT vs. CC + CT for atrophy: P = 0.07; for intestinal metaplasia: P = 0.01; for moderate-to-severe lesions: P = 0.01). OLGA and OLGIM stages III-IV were observed more frequently in patients with TT genotype compared with CC + CT genotypes (for OLGA: P = 0.003; for OLGIM: P = 0.036). Conclusions The MTHFR 677C > T TT genotype showed an increased risk of moderate-to-severe lesions by OLGA and OLGIM stages, and these results indicate that MTHFR C677T polymorphism may act as a predictive marker for precancerous gastric lesions, especially in Helicobacter pylori-negative patients aged ≤44 years.

Abstract
Premalignant gastric lesions such as atrophic gastritis and intestinal metaplasia frequently occur in subjects with long-term Helicobacter pylori (H. pylori) infection. The regular arrangement of collecting venules (RAC) is seen in the normal gastric corpus, whereas mucosal swelling and redness without RAC are observed in H. pylori-infected mucosa. Despite successful H. pylori eradication, the presence of atrophic gastritis and/or gastric intestinal metaplasia (GIM) is a risk factor for gastric cancer. With the development of advanced imaging technologies, recent studies have reported the usefulness of narrow-band imaging (NBI) for endoscopic diagnosis of atrophic gastritis and GIM. Using NBI endoscopy with magnification (M-NBI), atrophic gastritis is presented as irregular coiled microvessels and loss of gastric pits. Typical M-NBI endoscopic findings of GIM are a light blue crest and a white opaque substance. Based on the microvascular patterns, fine network, core vascular, and unclear patterns are useful for predicting gastric dysplasia in polypoid lesions. For diagnosis of early gastric cancer (EGC), a systematic classification using M-NBI endoscopy has been proposed on the basis of the presence of a demarcation line and an irregular microvascular/microsurface pattern. Furthermore, M-NBI endoscopy has been found to be more accurate for determining the horizontal margin of EGC compared to conventional endoscopy. In this review, we present up-to-date results on the clinical usefulness of gastroscopy with NBI for the diagnosis of H. pylori gastritis, precancerous gastric lesion, and neoplasia.

Abstract
PURPOSE OF THE REVIEW Atrophic gastritis is a complex syndrome with gastric atrophy as a common trait. Helicobacter pylori infection and autoimmunity are the two main contexts in which it develops. It is slightly symptomatic, affects various aspects of general health, and remains a predisposing factor for gastric cancer. This review will update current knowledge and progress on atrophic gastritis. RECENT FINDINGS Atrophic gastritis affects mostly adults with persistent dyspepsia, deficient anemia, autoimmunity disease, long-term proton pump inhibitor use, and a family history of gastric cancer. Gastric biopsies, expressed as Sydney system grade and OLGA/OLGIM classifications, represent the gold standard for diagnosis and cancer risk stage, respectively. Recently, electronic chromoendoscopy has allowed "targeted biopsies" of intestinal metaplasia. The associated hypochlorhydria affects the gastric microbiota composition suggesting that non-Helicobacter pylori microbiota may participate in the development of gastric cancer. Physicians should be aware of multifaceted clinical presentation of atrophic gastritis. It should be endoscopically monitored by targeted gastric biopsies. Autoimmune and Helicobacter pylori-induced atrophic gastritis are associated with different gastric microbial profiles playing different roles in gastric tumorigenesis.

Abstract
Gastritis is the term used to describe the inflammatory condition of the stomach. However, the ambiguous application of this term in clinical practice, such as in endoscopic or histological diagnosis, makes its diagnosis and treatment unclear. Atrophic gastritis is the most common finding in screening endoscopy, especially in patients with high risk of gastric adenocarcinoma; thus, definite diagnosis of the premalignant condition is important. Several classification systems and associated terminologies have been used to define the inflammatory condition of the stomach. However, many of them are based on histological findings, and their clinical application is limited in endoscopic diagnosis. Recently, with the advancement of endoscopic imaging techniques such as narrow-band imaging, atrophy and intestinal metaplasia can now be defined more precisely. Currently, many attempts have been made to classify the condition of the stomach on the basis of endoscopic findings, focusing on the risk of gastric adenocarcinoma and the presence of <i>Helicobacter pylori</i>.

Abstract
Paneth cells are residents of the intestinal epithelium. Abnormal appearance of Paneth cells has been widely documented in non-intestinal tissues within the digestive tract and even observed in non-gastrointestinal organs. Although metaplastic Paneth cells are part of the overarching pathology of intestinal metaplasia (IM), only a fraction of intestinal metaplastic lesions contain Paneth cells. We survey literature documenting metaplastic Paneth cells to gain insights into mechanism underlying their etiologic development as well as their potential relevance to human health. A synthesized view from this study suggests that the emergence of metaplastic Paneth cells at extra-intestinal mucosal sites likely represents a protective, anti-bacterial, and inflammatory response evoked by an altered microbial activity.

Abstract
The main modalities for gastric cancer screening are limited to upper gastrointestinal endoscopy and contrast radiography. The former is invasive, and the latter has high false-negative rates. Thus, alternative diagnostic strategies are required. One solution may be a liquid biopsy. Methylated RUNX3 is a well-known biomarker of gastric cancer but it is very difficult to detect with conventional bisulfite-based methylation assays when only a small amount of serum is available. We developed the combined restriction digital PCR (CORD) assay, a new methylation assay allowing for the counting of as little as one copy of a methylated gene in a small sample of DNA without necessitating DNA bisulfite treatment. We evaluated the sensitivity and specificity of the serum DNA testing of methylated RUNX3 by the CORD assay for the detection of early gastric cancer using 50 patients with early gastric cancer and 61 control individuals. The CORD assay had a sensitivity of 50.0% and a specificity of 80.3% for early gastric cancer. Methylated RUNX3 copies were significantly associated with tumor size, massive submucosal invasion, and lymph-vascular invasion. After the treatment, the median number of methylated RUNX3 copies was significantly decreased. The CORD assay may provide an alternative screening strategy to detect even early-stage gastric cancer.

Abstract
Introduction: Atrophic gastritis (AG) is a complex syndrome which arises as a consequence of H. pylori infection or in the context of gastric autoimmunity. It often deserves a benign course but may lead to potentially life-threatening complications: cancer and anemia. This review aims to address traditional and innovative knowledge on this often under-diagnosed disorder.Areas covered: This review covers clinical presentation, risk factors, diagnosis, and management of AG and provides an updated resource for clinicians to get insight into this challenging disorder. Updated literature was searched in PubMed. Manual search from reference lists of publications was performed.Expert opinion: A case-finding strategy may be beneficial in individuals with anemia, dyspepsia, autoimmune thyropaties and type 1 diabetes, and family history of gastric cancer. AG is linked to gastric cancer risk and endoscopic surveillance is indicated according to topography of gastric atrophy and risk factors. The direction for future research in AG is summarized.

Abstract
Objective: Long-term administration of proton pump inhibitors (PPIs) after eradication of Helicobacter pylori infection has been reported to increase the risk for development of gastric cancer (GC). We investigated whether long-term administration of PPI affects ectopic and metachronous recurrence of GC after endoscopic treatment.Methods: Participants were 687 patients who underwent endoscopic treatment for GC from January 2005 to March 2018. Questionnaire surveys and medical record reviews of medications, including PPIs, H2 receptor antagonists and low-dose aspirin (LDA) were conducted for all patients. The influence of PPI in ectopic and metachronous recurrence of GC was evaluated with Cox's proportional hazard analysis.Results: Patients who did not respond to the questionnaire and those who underwent additional treatment after endoscopic treatment were excluded from analyses; 418 patients were included. During an average observation period of 1608 days (range, 375-4993 days), 136 patients (32.5%) took PPIs for more than 1 year and 94 took PPIs for more than 3 years; of those, 40 had ectopic and metachronous recurrences. Cox's proportional hazards analysis revealed that long-term use of PPIs (for both 1 year and 3 years) was not a risk factor for recurrence. In addition, age, severity of gastric atrophy, long-term use of LDA, current infection with H. pylori, and cure achieved with the first endoscopic treatment were also not risk factors for recurrence.Conclusions: Long-term use of PPIs does not affect ectopic and metachronous recurrence of GC after endoscopic treatment.

PLoS One 2019; 14:e0226427. [PMID: 31851694 PMCID: PMC6919620 DOI: 10.1371/journal.pone.0226427] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 11/26/2019] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Gastric cancer (GC) is categorized as diffuse- and intestinal-type adenocarcinoma. Intestinal-type GC is associated with chronic gastritis, atrophic gastritis (AG), and intestinal metaplasia (IM), precursors of dysplastic changes. Diffuse-type GC is generally known to undergo de novo carcinogenesis and is not associated with chronic mucosal changes. However, clinically, AG and IM are frequently observed surrounding diffuse-type GC. This study aimed to evaluate the role of AG and IM in diffuse-type GC. METHODS We retrospectively reviewed the data of patients undergoing surgery for early GC. We divided patients with diffuse-type GC into two groups according to the presence of AG and IM based on Kyoto classification of gastritis. The clinicopathological characteristics were compared between the groups. RESULTS Among patients with diffuse-type GC, 52.5% patients had AG and 18.4% had severe AG. With regard to IM, 42.1% patients had IM and 17.1% had severe IM. Diffuse-type GC combined with severe AG or IM showed larger tumor size and higher submucosal invasion rate than that without severe AG or IM. However, the lymph node metastasis (LNM) rate was not significantly different between the two groups. In multivariate analysis, severe AG or IM was not an independent risk factor for LNM. CONCLUSIONS Severe AG or IM surrounding diffuse-type gastric cancer suggests a collapse of normal mucosal barriers and leads to the spread of cancer cells. Although the association between chronic mucosal changes and LNM is unclear, more caution is needed during endoscopy especially for complete resection of diffuse-type GC with these features.

Abstract
Detection of early-stage gastric cancer improves the prognosis of patients. Endoscopic submucosal dissection (ESD) is a curative and stomach-preserving treatment for early gastric cancer (EGC) associated with a low risk of lymph node metastasis. However, several studies have reported missed diagnosis of gastric cancer. Therefore, endoscopists are required to learn accurate diagnostic skills to eliminate endoscopic blind spots. A systematic screening protocol to map the entire stomach without blind spots reduces the risk of missed lesions. Knowledge of the features of EGC or dysplasia is essential to identify suspicious lesion. Information of the common sites of occurrence of EGC can also enable a detailed endoscopic examination to improve detection rates. Previous reports investigating the location of gastric cancers resected by ESD or surgery showed that the antrum and lesser curvature of stomach were predominantly affected. Helicobacter pylori-induced atrophic changes advance from the antrum to the corpus along the lesser curvature, predominantly affecting these areas. Gastric cancers in the antrum and the lower corpus are also commonly missed during screening examination. Therefore, a careful examination of the lower third stomach is warranted to avoid missing synchronous and metachronous gastric lesions. Knowledge of the location of EGC enables accurate endoscopic examination and detection of EGC in early stage.

Abstract
The assessment of endoscopic gastric atrophy (EGA) according to the Kimura-Takemoto classification has been reported to correlate well with histological assessment. Although agreement among beginner endoscopists was less than that among experienced endoscopists, it has been shown that agreement level could markedly improve and remained stable after proper training. Several cohort studies have consistently shown that the severity of EGA at baseline is significantly associated with the presence of advanced precancerous gastric lesions and gastric cancer, as well as the development of gastric cancer in future. Patients with moderate-to-severe EGA still have high risk of gastric cancer even after successful Helicobacter pylori eradication and should be candidates for gastric cancer surveillance. The assessment of EGA, therefore, could be used as a preliminary tool to identify individuals at high risk for gastric cancer. In this paper, we review the agreement on mucosal atrophy assessment between the Kimura-Takemoto classification and histology as well as the potential application of this endoscopic classification to identify precancerous gastric lesions and gastric cancer in daily practice.

Abstract
Background/Aims Proton pump inhibitors are widely used to prevent gastric endoscopic submucosal dissection (ESD)-related bleeding, but no standard administration regimens have been established. We aimed to prospectively compare the effects of continuous infusion and intermittent dosing with pantoprazole on preventing gastric ESD-related bleeding. Additionally, we analyzed the risk factors for bleeding. Methods From April 2012 to May 2013, patients with a gastric epithelial neoplasm scheduled for ESD in the Pusan National University Hospital were randomly assigned to one of two groups according to the pantoprazole administration regimen (continuous infusion or intermittent dosing). The primary outcomes measured were intra- and postprocedural bleeding events. Results The final analysis included 401 patients. The rate of significant intraprocedural bleeding was 25.4% in the C group and 24.0% in the I group, with no significant difference (p=0.419). In addition, there was no significant difference in the postprocedural bleeding rate between the C and I groups (11.7% vs 10.2%, p=0.374). Multivariate analysis showed that intraprocedural bleeding was associated with the proximal tumor location, the presence of fibrosis, and the size of the resected specimen, whereas postprocedural bleeding was associated with the size of the resected specimen and the procedure/coagulation time. Conclusions Intermittent dosing with pantoprazole is sufficient and cost-effective for the prevention of gastric ESD-related bleeding. Operators should consider tumor characteristics when planning ESD to minimize the risk of intraprocedural bleeding, and patients with large iatrogenic ulcers should be carefully monitored for postprocedural bleeding.

Abstract
Objective The association between functional dyspepsia (FD) and endoscopic findings has not been fully elucidated. Helicobacter pylori infection is considered a key factor in the pathophysiology of FD. The Kyoto Classification of Gastritis (KCG) was proposed in 2014 to evaluate endoscopic findings based on the H. pylori status. We investigated the endoscopic findings associated with FD according to the KCG. Methods This cross-sectional study included subjects who underwent esophagogastroduodenoscopy during a medical health check-up. We compared the endoscopic findings between subjects with FD and healthy controls (HCs) according to the KCG. Results A total of 456 subjects were analyzed. Among them, the detection rate of FD was 5.5% (25/456 persons). In a univariate analysis of the endoscopic findings, a significantly lower proportion of subjects with FD had gastric red streak in comparison to HCs (0% vs. 18.6%, respectively; p=0.0124). Subjects with FD were more likely to have gastric depressive erosion (20.0% vs. 7.9%; p=0.0522). A higher proportion of the erosion-positive subjects had FD in comparison to erosion-negative subjects (12.8% vs. 4.8%). There were no significant differences in the other endoscopic findings, including gastric atrophy, intestinal metaplasia, enlarged fold, nodularity, and diffuse redness. A multivariate analysis revealed that gastric depressive erosion was significantly and independently associated with FD (odds ratio, 2.92; 95% confidence interval, 1.03-8.26; p=0.0436). In contrast, gastric red streak was not associated with FD (p=0.989). Conclusion Gastric depressive erosions may be associated with dyspepsia.

Abstract
Vonoprazan, a potassium-competitive acid blocker, is a new class of acid-suppressing agent. The acid-inhibitory effect of vonoprazan has been well-documented. However, there is no report on the extent to which the amount of gastric acid secretion is suppressed, not pH measurement, by the use of vonoprazan. The aim of this study was to evaluate this suppression effect. This was a single-arm, interventional pilot study involving 7 healthy Japanese men. The subjects were administered 20 mg vonoprazan for 6 days. The amount of gastric acid secretion was determined using the calcium carbonate breath test. The acid outputs were defined as the maximum Δ13C‰ (Δ13C max) and area under the curve (AUC) during the 30 min sampling period. The Δ13C max and AUC values significantly decreased on the administration of 20 mg vonoprazan. The AUC dropped by approximately 78% on day 1 and by 84% on day 6 and subsequently returned to the control level after cessation of vonoprazan therapy (reduction by 68% on day 7 and by 42% on day 8). In conclusion, the amount of gastric acid secretion rapidly decreased by the administration of vonoprazan; this inhibitory effect was found to be potent and long-lasting. (UMIN ID: UMIN000025469).

Abstract
Helicobacter pylori (Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection. There is no ideal treatment for Hp. Hp infection is not cured by a single antibiotic, and sometimes, a combined treatment with three or more antibiotics is ineffective. Atrophic gastritis (AG) is a chronic disease whose main features are atrophy and/or intestinal metaplasia of the gastric glands, which arise from long-standing Hp infection. AG is reportedly linked to an increased risk for gastric cancer, particularly when extensive intestinal metaplasia is present. Active or past Hp infection may be detected by conventional methods in about two-thirds of AG patients. By immunoblotting of sera against Hp whole-cell protein lysates, a previous exposure to Hp infection is detected in all AG patients. According to guidelines, AG patients with Hp positivity should receive eradication treatment. The goals of treatment are as follows: (1) Cure of infection, resolution of inflammation and normalization of gastric functions; (2) possible reversal of atrophic and metaplastic changes of the gastric mucosa; and (3) prevention of gastric cancer. An ideal antibiotic regimen for Hp should achieve eradication rates of approximately 90%, and complex multidrug regimens are required to reach this goal. Amongst the factors associated with treatment failure are high bacterial load, high gastric acidity, Hp strain, smoking, low compliance, overweight, and increasing antibiotic resistance. AG, when involving the corporal mucosa, is linked to reduced gastric acid secretion. At a non-acidic intra-gastric pH, the efficacy of the common treatment regimens combining proton pump inhibitors with one or more antibiotics may not be the same as that observed in patients with Hp gastritis in an acid-producing stomach. Although the efficacy of these therapeutic regimens has been thoroughly tested in subjects with Hp infection, there is a paucity of evidence in the subgroup of patients with AG. Bismuth-based therapy may be an attractive treatment in the specific setting of AG, and specific studies on the efficacy of bismuth-based therapies are needed in patients with AG.

Abstract
Background/Aims There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Methods Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. Results There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76–4.88) and RE (OR, 3.41; CI 95%, 1.78–6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) (P < 0.001). Conclusions Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

Endoscopic grading of gastroesophageal f lap valve is simple, reproducible, and may predict reflux activity. We investigated the correlation between gastroesophageal flap valve grade and the gastroesophageal junction's structural properties using abdominal computed tomography. METHODS A total of 138 patients with early gastric cancer who underwent both pre-treatment esophagogastroduodenoscopy and water-distended stomach two-phase computed tomography were enrolled. Endoscopic gastroesophageal f lap valve grade and abdominal computed tomography findings were analyzed to assess anatomical factors including the gastroesophageal junction and related organs. RESULTS The angle of His increased significantly with gastroesophageal flap valve grade (grade I, 65.2˚ ± 19.6˚; grade II, 66.6˚ ± 19.8˚; grade III, 76.7˚ ± 11.9˚; grade IV, 120.0˚ ± 30.3˚; p < 0.001), as did the size of the diaphragmatic hiatus (grade I, 213.0 ± 53.8 mm2 ; grade II, 232.6 ± 71.0 mm2 ; grade III, 292.3 ± 99.2 mm2 ; grade IV, 584.4 ± 268.3; p < 0.001). The length of the abdominal esophagus decreased as gastroesophageal flap valve grade increased (grade I, 34.6 ± 5.8 mm; grade II, 32.0 ± 6.5 mm; grade III, 24.6 ± 7.8 mm; grade IV, -22.6 ± 38.2 mm; p < 0.001). There was no significant relationship between gastroesophageal flap valve grade and visceral and subcutaneous fat areas (p = 0.877 and p = 0.508, respectively). CONCLUSIONS Endoscopic grading of the gastroesophageal flap valve is well correlated with anatomical changes around the gastroesophageal junction on abdominal computed tomography, and it can provide useful information about the anti-reflux barrier.

Abstract
Despite a significant decrease in the incidence of gastric cancer in Western countries over the past century, gastric cancer is still one of the leading causes of cancer-related deaths worldwide. Most human gastric cancers develop after long-term Helicobacter pylori infection via the Correa pathway: the progression is from gastritis, atrophy, intestinal metaplasia, dysplasia, to cancer. However, it remains unclear whether metaplasia is a direct precursor of gastric cancer or merely a marker of high cancer risk. Here, we review human studies on the relationship between metaplasia and cancer in the stomach, data from mouse models of metaplasia regarding the mechanism of metaplasia development, and the cellular responses induced by H. pylori infection.

Abstract
BACKGROUND Erosive reflux disease (ERD) is prevalent in the West, and its incidence is increasing in the East. The differences between the West and East, especially in body composition, have not been investigated thoroughly. METHODS Subjects who underwent esophagogastroduodenoscopy and body composition analysis during health screening were analyzed retrospectively. Russian Caucasians who visited Korea were propensity matched with native Koreans. Endoscopy results were analyzed to identify ERD and gastroesophageal flap valve (GEFV) status. Body composition and laboratory results were compared to identify risk factors for ERD. KEY RESULTS 32 279 subjects underwent health screening with 1496 Russian Caucasians propensity matched with 1496 Koreans. ERD prevalence was 20.2% for Caucasians and 9.8% for Koreans (P<.001). Caucasians had significantly greater body mass index (BMI) and were more sarcopenic. Significant risk factors for ERD were Caucasian ethnicity (OR 1.629, 95% CI 1.265-2.099, P<.001), male gender (OR 2.374, 95% CI 1.883-2.993, P<.001), greater BMI (OR 1.067, 95% CI 1.041-1.093, P<.001), and abnormal GEFV (OR 2.730, 95% CI 2.194-3.397, P<.001). H. pylori seropositivity (OR 0.614, 95% CI 0.488-0.774, P<.001) and atrophic gastritis (OR 0.547, 95% CI 0.411-0.728, P<.001) were significantly preventive. CONCLUSIONS & INFERENCES Caucasian ethnicity is a significant risk factor for ERD. Greater BMI, male gender and abnormal GEFV are associated with ERD, and H. pylori seropositivity and atrophic gastritis are preventive. Further studies are needed to assess the differences in ERD between Caucasians and East Asians.

Abstract
BACKGROUND AND AIM Use of proton pump inhibitors (PPI) is histologically associated with oxyntic gland dilatations. Two interesting mucosal changes are often detected endoscopically in patients who use PPI: gastric cracked mucosa (GCM) and gastric cobblestone-like mucosa (GCSM). The aim of the present study was to clarify the relationship between PPI use and these mucosal changes. METHODS This was a single-center observational study. All successive subjects who underwent a routine esophagogastroduodenoscopy (EGD) between August and November 2014 in Hokkaido University Hospital were enrolled. Endoscopists carried out the assessment blinded to the use of PPI and checked for GCSM and GCM using original diagnostic criteria for GCM and GCSM. Subjects were divided into two groups: those who used PPI (PPI group) and those who did not (control group). Endoscopic findings and backgrounds were compared between the two groups. RESULTS A total of 538 patients were analyzed (control group: 374 patients, men/women: 204/170, median age: 65.2 years; PPI group: 164 patients, men/women: 89/75, median age: 67.1 years). GCM was detected in 54 (10.0%) subjects, and GCSM was detected in 18 (3.3%) subjects. There was a significant difference in the prevalence rate of GCM between the control group (14/374, 3.7%) and the PPI group (40/164, 24.4%) (P < 0.01). GCSM was significantly more prevalent in the PPI group (15/164, 9.1%) than in the control group (3/374, 0.8%) (P < 0.01). CONCLUSION Novel GCM and GCSM endoscopic findings in the corpus area seem to be strongly associated with PPI use.

Abstract
BACKGROUND AND STUDY AIMS The timely detection of early gastric cancer (EGC) is important in performing endoscopic submucosal dissection (ESD). We attempted to determine the location characteristics of regions where EGC is frequently detected and analyzed the EGC characteristics associated with that location. METHODS We retrospectively reviewed the medical records of patients with EGC treated by ESD between November 2008 and August 2016. We retrospectively investigated and analyzed 647 EGC lesions. RESULTS The patients' mean age was 66.7 ± 10.8 years. The patient population was predominantly male (77.1%, 499/647). A well-to-moderately differentiated carcinoma was observed in 97.2% of patients. The common site of carcinoma occurrence was the lower part of the stomach (the antrum and lower third of body, 89.6%). Among the stomach hemispheres, the lesser curvature side was the most frequent site of EGC (43.9%). The posterior side of EGC was more frequent than anterior side of EGC (20.4 vs. 15.6%, respectively). Submucosal invasive EGC was more frequent in the mid-to-upper parts of stomach than lower part of stomach (odds ratio 1.919; confidence interval 1.014-3.623; p = 0.045). CONCLUSIONS Most EGCs that are resectable with ESD were found in the lower part and in the lesser curvature of the stomach. The submucosal invasive EGC was more frequent in the mid-to-upper part of stomach.

Abstract
BACKGROUND Previous morphological studies indicated that the eradication of Helicobacter pylori (H. pylori) made gastric neoplasms endoscopically indistinct through the flattening and covering of tumors with a non-neoplastic epithelium (NE). AIM To validate these alterations. METHODS We reviewed and compared the endoscopic and histological findings of early gastric carcinomas and high-grade dysplasias resected endoscopically from H. pylori-infected and H. pylori-eradicated patients. The extent of NE covering a tumor was expressed as the histological length ratio of NE to the tumor. Tumor morphology was compared before and after therapies in patients who received H. pylori eradication treatments during the period from tumor discovery to endoscopic resection. RESULTS NE-covered ratios were higher in the 59 tumors detected after the eradication of H. pylori than in the 152 tumors detected during the infection (median 8 vs. 0 %, respectively), whereas the frequency at which an elevated morphology and whitish discoloration of a tumor were observed was less (14 vs. 56 %, and 14 vs. 43 %, respectively). These were also independent characteristics for tumors detected after the eradication of H. pylori. Two elevated tumors showing whitish discoloration out of 16 tumors became endoscopically indistinct following H. pylori eradication treatments through the flattening of tumors and muting of the discoloration. CONCLUSION The eradication of H. pylori promoted covering with NE, the flattening of tumors, and muting of the whitish discoloration, which may make a subset of tumors, potentially including whitish elevated neoplasms, indistinct.

Abstract
BACKGROUND Upper gastrointestinal endoscopy (UGI-ES) and double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) are two major image-based methods to diagnose atrophic gastritis, which is mostly induced by Helicobacter pylori infection. However, there have been few studies directly comparing them. METHODS Atrophic gastritis was evaluated using the data of 962 healthy subjects who underwent UGI-ES and UGI-XR within 1 year. RESULTS AND CONCLUSION Based on UGI-ES and UGI-XR, 602 subjects did not have atrophic gastritis and 254 subjects did have it. Considering UGI-ES-based atrophic gastritis as the standard, sensitivity and specificity of UGI-XR-based atrophic gastritis were 92.0 % (254/276) and 92.8 % (602/649), respectively. The seven-grade Kimura-Takemoto classification of UGI-ES-based atrophic gastritis showed a strong and significant association with the four-grade UGI-XR-based atrophic gastritis. Sensitivity and specificity of serum anti-Helicobacter pylori IgG to detect UGI-ES/UGI-XR-based atrophic gastritis were 89.4 % (227/254) and 99.8 % (601/602), indicating that atrophic gastritis can be overlooked according to serum anti-Helicobacter pylori IgG alone.

Abstract
BACKGROUND/AIMS It remains unclear whether atrophic gastritis can affect dyspeptic symptoms. We aimed to investigate whether the extent of atrophic gastritis is associated with specific dyspeptic symptoms. METHODS Consecutive adults in a routine health-checkup program were enrolled in the study. The extent of atrophic gastritis was classified into 3 groups based on the Kimura-Takemoto criteria; the gastritis with no or little atrophy (group A: C0), the gastritis with atrophy mainly in the antrum (group B: C1 and C2), and the gastritis with atrophy in the large area of the corpus (group C: C3 and O). Upper gastrointestinal symptoms were categorized into "typical reflux symptoms," "epigastric pain syndrome (EPS)-related symptoms," and "postprandial distress syndrome (PDS)-related symptoms." RESULTS A total of 1827 patients (1009 males, mean age 45.1 years) were included in the analysis. The subgroups of atrophic gastritis were as follows: group A (n = 1218, 66.7%), group B (n = 392, 21.4%), and group C (n = 217, 11.9%). Typical reflux, EPS-related, and PDS-related symptoms were present in 10.5%, 19.8%, and 16.2% of the subjects, respectively. PDS-related and EPS-related symptoms were significantly more prevalent in the group C of male patients and the group B of female patients, respectively, compared with other groups. PDS-related and EPS-related symptoms were independently associated with the group C in males (OR, 2.123; 95% CI, 1.090-4.136) and the group B in females (OR, 2.571; 95% CI, 1.319-5.025), respectively. CONCLUSIONS The extent of atrophic gastritis appears to affect the generation of specific dyspeptic symptoms in a gender-dependent manner.

Abstract
OBJECTIVE To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. DESIGN Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. RESULTS All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. CONCLUSIONS A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

Abstract
Antiplatelet drugs are widely used for the prevention of cardiovascular disease and cerebral vascular disorders. Although there have been several studies on gastroduodenal mucosal injury with gastrointestinal (GI) symptoms such as GI bleeding, in antiplatelet drug users (including low-dose aspirin (LDA)), there have been few reports on the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users. This study was a cross-sectional study elucidating the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Subjects were 186 asymptomatic Japanese antiplatelet drug users who underwent a regular health checkup. Subjects were divided into those with and without gastroduodenal mucosal injury endoscopically, and the association between gastroduodenal mucosal injury and other data in asymptomatic antiplatelet drug users was investigated.The prevalence of males and drinkers were significantly higher in subjects with gastroduodenal mucosal injury than in those without. In addition, the prevalence of proton pump inhibitor (PPI) users was significantly lower in subjects with gastroduodenal mucosal injury than in subjects without gastroduodenal mucosal injury. Logistic regression analysis showed PPI (odds ratios: 0.116; 95% confidence intervals: 0.021-0.638; P < 0.05) was a significant predictor of a decreased prevalence of gastroduodenal mucosal injury and closed-type (C-type) atrophy (3.172; 1.322-7.609; P < 0.01) was a significant predictor of an increased prevalence of severe gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Gender and lifestyle, such as drinking, may have an impact on risk of gastroduodenal mucosal injury in asymptomatic subjects taking antiplatelet drugs. Although PPI is a significant predictor of a decreased prevalence of gastroduodenal mucosal injury, including in asymptomatic antiplatelet drug users, status of gastric atrophy should also be considered against severe gastroduodenal mucosal injury.

Abstract
Atrophic gastritis (AG) and intestinal metaplasia (IM) are the main precursor lesions of gastric cancer as the incidence of gastric cancer increases in the gastric mucosa involved with AG and IM. The prevalence of AG and IM vary depending on countries, even it represents diverse results in the same nation. Usually AG is antecedent of IM but the etiologies of AG and IM are not always the same. The sensitivity and specificity of diagnostic methods to detect AG and IM are different. Furthermore, the management strategy of AG and IM has not been established, yet. Helicobacter pylori infection has been proved as the most important cause of AG and IM. Thus the eradication of H. pylori is very important to prevent the progression to gastric cancer which is still placed in the high rank in morbidity and mortality among cancers. However, the reversibility of AG and IM by eradication of H. pylori which was assumed to be certain by meta-analysis is; however, controversial now. Therefore, the understanding and early diagnosis of AG and IM are very important, especially, in high incidence area of gastric cancer such as Republic of Korea.

Abstract
BACKGROUND AND AIM We recently encountered patients with localized esophageal eosinophilia in a small area of the esophagus. However, this condition remains to be described in detail, and its clinical significance has not been established. We investigated the clinical, endoscopic and histological features of localized esophageal eosinophilia in comparison with diffuse esophageal eosinophilia. METHODS We investigated 10 patients with localized esophageal eosinophilia, and compared them with 23 who had diffuse esophageal eosinophilia. Whether esophageal eosinophilia was localized or diffuse was determined on the basis of endoscopic findings. Localized esophageal eosinophilia was defined endoscopically as a focal area of esophageal eosinophilia, whereas diffuse esophageal eosinophilia was defined as a widespread area of esophageal eosinophilia involving more than one of three locations: the upper, middle and lower esophagus. Histological esophageal eosinophilia in the mucosa showing endoscopic abnormality was confirmed by biopsy with a peak of ≥ 15 eosinophils/high-power field. RESULTS There were no significant differences in age, gender distribution, allergic conditions or peripheral eosinophilia between the two groups. In all cases but one, localized esophageal eosinophilia was observed in a small area above the esophagogastric junction. Esophageal symptoms such as dysphagia, heartburn or chest pain were present in 20% of the localized group and in 65% of the diffuse group, the difference being statistically significant (P<0.05). The maximum amounts of eosinophils infiltrating the esophageal mucosa did not differ between the groups. CONCLUSIONS Esophageal eosinophilia can be localized in a small area, especially above the esophagogastric junction. Gastric acid reflux or contact may influence this condition in addition to its allergic pathogenesis.

Abstract
Irrespective of its etiology, long-standing, non-self-limiting gastric inflammation (mostly in Helicobacter pylori-associated cases) is the cancerization ground on which epidemic (intestinal-type) gastric carcinoma (GC) can develop. The natural history of invasive gastric adenocarcinoma encompasses gastritis, atrophic mucosal changes, and intraepithelial neoplasia (IEN). The topography, the extent and the severity of the atrophic changes significantly correlate with the risk of developing both IEN and GC. In recent years, both noninvasive (serological) tests and invasive (endoscopy/biopsy) procedures have been proposed to stratify patients according to different classes of GC risk. As a consequence, different patient-tailored GC secondary prevention strategies have been put forward. This review summarizes the histological features of H. pylori-related gastritis and the natural history of the disease. Histological and serological strategies to assess GC risk as well as the clinical management of atrophic gastritis patients are also discussed.

Abstract
OBJECTIVE The Japanese health insurance system approved the use of proton pump inhibitors (PPIs) for the prevention of peptic ulcers in patients using low-dose aspirin (LDA) and/or non-steroidal anti-inflammatory drugs (NSAIDs). However, many orthopedists and physicians do not prescribe PPIs to elderly patients with atrophic gastritis. The aim of this study was to determine whether PPIs are effective in preventing gastrointestinal mucosal injury in elderly Japanese patients with atrophic gastritis. METHODS We examined the associations between the use of antiulcer drugs and endoscopic findings in elderly Japanese patients using LDA or NSAIDs. Patients We evaluated 100 patients using LDA and 58 patients using non-aspirin NSAIDs 65 years of age or older. All patients underwent upper GI endoscopy to detect the presence of open ulcers and hemorrhagic lesions and assess the extent of atrophic gastritis. RESULTS Among the patients using LDA, the prevalence of open ulcers was significantly lower in the patients using PPIs than in those using mucosal protective agent only and those not receiving antiulcer treatment (p<0.001). Among the patients using NSAIDs, the patients treated with PPIs exhibited a significantly lower incidence of open ulcers than the patients not receiving antiulcer treatment (p=0.012). Open-type atrophic gastritis was observed in nearly 70% of the patients. CONCLUSION The use of PPI treatment is advisable in order to prevent the discontinuation of LDA or NSAIDs due to the development of gastrointestinal disorders in elderly patients with atrophic gastritis.

Abstract
Background/Aims Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. Given the benign nature of the condition and the association of gastroesophageal reflux disease, empirical therapy with proton pump inhibitor seems reasonable for patients with typical globus. The aim of this study was to investigate the clinical predictors for symptom response to short-term proton pump inhibitor treatment in patients with globus symptom. Methods Fifty-four patients with globus symptom were enrolled prospectively. All patients were treated with pantoprazole 40 mg daily for 4 weeks. Treatment response was defined as a > 50% reduction in symptom scores between symptom assessments. Univariate and multivariate logistic regression analysis between responders and non-responders was performed to identify variables predicting response to pantoprazole treatment. Results Of the 54 consecutive patients considered, 13 were excluded on the basis of exclusion criteria and/or refusal to participate in the study. Finally, 41 patients were included in this study. After 4-week pantoprazole treatment, 22 patients (53.7%) were classified as responders. On multivariate analysis, the presence of reflux symptom was associated with a higher response rate to 4-week pantoprazole treatment (OR, 68.56; P = 0.043), and long symptom duration (≥ 3 months) were associated with a lower response rate to pantoprazole treatment (OR, 0.03; P = 0.034). Conclusions Presence of reflux symptom and short symptom duration were independent predictors of responsiveness to 4-week pantoprazole treatment in patients with globus.

Abstract
OBJECTIVE The majority of ghrelin producing cells (GPC) are present in the fundic gland of the stomach and recognized as X/A like cells. The detailed distribution of GPC in the stomach is still unknown in healthy and pathological subjects. METHODS We investigated the detailed distribution of GPC in the stomach, especially in relation with chronic gastritis, using surgical specimens from 12 patients with early gastric cancer. Either the anterior or posterior half of the whole stomach, which was a counterpart of the tumor bearing side, was subjected for immunohistochemistry of ghrelin, and the number of total GPC were semi quantitatively evaluated as GPC score. GPC score was compared with the degree of chronic gastritis, serum ghrelin concentration and body weight. RESULTS GPC was not observed in the pyloric gland, but heterogeneously distributed in the fundic gland mainly in upper body and the greater curvature. The GPC score showed about nine-fold difference, which correlated well with the degree of chronic gastritis by Sydney score (r = -0.84, P < 0.001). The serum ghrelin concentration was basically determined by the GPC score (r = 0.75, P = 0.0047); however, the obese patients showed low serum ghrelin concentration in spite of the presence of abundant GPCs. In the low GPC score patients, serum ghrelin was constantly low regardless of their body weight. CONCLUSIONS GPC was inversely correlated with progression of chronic gastritis. Its quantification using immunohistochemistry of the whole stomach was useful to comprehensively evaluate ghrelin profile.

Abstract
The decreased ratio of serum pepsinogen (PG) I and II has good correlation with the presence of atrophic gastritis. A total of 1,540 residents aged 30-89 years were enrolled into this study to investigate which serum PG level of residents with Helicobacter pylori infection would represent an adjunct to the diagnosis and progression of atrophic gastritis. All participants received esophagogastroduodenoscopy. Serum antibody to H. pylori (anti-H. pylori) was measured by an enzyme-linked immunosorbent assay (ELISA). Serological atrophic gastritis was defined as serum PG I isozyme level ≤70 ng/ml and a PG I/II ratio of ≤3.0. Of the 1,540 participants, 923 (59.9%) were positive for anti-H. pylori. Serological atrophic gastritis was found significantly more often in anti-H. pylori-positive participants (40.8%) than in anti-H. pylori-negative participants (7.9%) (p ≤ 0.0001). The endoscopic findings of anti-H. pylori-positive participants with serological atrophic gastritis were significantly more frequent by 4.06 times for atrophic gastritis (p ≤ 0.0001) than anti-H. pylori-negative participants without serological atrophic gastritis. Eight anti-H. pylori-positive participants were diagnosed with gastric cancer, but no cancer was found in anti-H. pylori-negative participants without serological atrophic gastritis. Serum PG testing is clinically useful for the prediction of gastric lesions in H. pylori-infected persons.

Abstract
BACKGROUND AND AIMS Atrophic gastritis (AG) results most often from Helicobacter pylori (H. pylori) infection. AG is the most important single risk condition for gastric cancer that often leads to an acid-free or hypochlorhydric stomach. In the present paper, we suggest a rationale for noninvasive screening of AG with stomach-specific biomarkers. METHODS The paper summarizes a set of data on application of the biomarkers and describes how the test results could be interpreted in practice. RESULTS In AG of the gastric corpus and fundus, the plasma levels of pepsinogen I and/or the pepsinogen I/pepsinogen II ratio are always low. The fasting level of gastrin-17 is high in AG limited to the corpus and fundus, but low or non-elevated if the AG occurs in both antrum and corpus. A low fasting level of G-17 is a sign of antral AG or indicates high intragastric acidity. Differentiation between antral AG and high intragastric acidity can be done by assaying the plasma G-17 before and after protein stimulation, or before and after administration of the proton pump inhibitors (PPI). Amidated G-17 will rise if the antral mucosa is normal in structure. H. pylori antibodies are a reliable indicator of helicobacter infection, even in patients with AG and hypochlorhydria. CONCLUSIONS Stomach-specific biomarkers provide information about the stomach health and about the function of stomach mucosa and are a noninvasive tool for diagnosis and screening of AG and acid-free stomach.

Abstract
OBJECTIVE Limited information is available on predictors of the response to proton pump inhibitor (PPI) treatment in patients with gastroesophageal reflux disease (GERD). Endoscopic grading of gastroesophageal flap valve (GEFV) is simple and reproducible, and can provide useful information on patients with suspected reflux undergoing an endoscopy. The aim of this study was to prospectively identify predictors, including endoscopic findings such as GEFV, for PPI treatment outcomes in patients with GERD. MATERIAL AND METHODS One hundred and fifty consecutive patients with GERD were enrolled. All patients were treated with pantoprazole 40 mg daily for 8 weeks. Treatment response was defined as greater than 50% reduction in symptom scores between the two symptom assessments (i.e., over 4 or 8 weeks). Univariate and multivariate logistic regression analyses between responders and non-responders were performed to identify variables predicting response to pantoprazole treatment. RESULTS Of the 150 consecutive patients considered for this study, 31 were excluded based on exclusion criteria and/or refusal to participate, leaving 119 eligible patients. After 4-week pantoprazole treatment, 70 of 119 (58.8%) patients were classified as responders. Patients with obesity and Helicobacter pylori infection demonstrated a higher response rate to 4-week pantoprazole treatment (odds ratio (OR) 5.28, p = 0.008; OR 3.76, p = 0.023, respectively). Patients with abnormal GEFV showed a lower response rate to 4-week treatment (OR 0.17, p = 0.016). After 8-week treatment, 86 of 119 (72.3%) patients were classified as responders. Abnormal GEFV and aspirin intake were associated with a lower response rate to 8-week treatment (OR 0.17, p = 0.021; OR 0.11, p = 0.020, respectively). CONCLUSIONS Abnormal GEFV was a significant independent factor predicting poor response to both 4-week and 8-week pantoprazole treatment. Endoscopic grading of GEFV provides useful information for predicting the response to PPI treatment in patients with GERD.

Etiological difference between ultrashort- and short-segment Barrett's esophagus. J Gastroenterol 2011; 46:332-8. [PMID: 21132333 DOI: 10.1007/s00535-010-0353-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2010] [Accepted: 11/08/2010] [Indexed: 02/04/2023]
Abstract
BACKGROUND Barrett's esophagus has been divided into three categories based on the extent of the metaplasia: long-segment (LSBE), short-segment (SSBE), and ultrashort-segment Barrett's esophagus (USBE). While both LSBE and SSBE are thought to be induced by gastroesophageal reflux, the etiology of USBE is still unclear. METHODS We conducted a case-control study to identify the differences in the pathogenesis between SSBE and USBE in a hospital-based population. The endoscopic findings and clinical factors of 199 patients with short-segment endoscopically suspected esophageal metaplasia (SS-ESEM) and 317 patients with ultrashort-segment ESEM (US-ESEM) were compared with those of 199 and 317 age- and gender-matched patients without ESEM. RESULTS The severity of gastric mucosal atrophy was marginally associated with the presence of US-ESEM [odds ratio (OR) 1.20, 95% confidence interval (CI) 0.98-1.46, p = 0.08], but not with that of SS-ESEM. On the other hand, the presence of gallstones and that of severe reflux esophagitis were associated with the presence of SS-ESEM (OR 2.19, 95% CI 1.21-3.98; OR 1.72, 95% CI 1.08-2.75), but not with that of US-ESEM. Presence of gastric corpus atrophy without gallstones was associated with the presence of US-ESEM, but not with that of SS-ESEM. CONCLUSIONS Presence of gastric corpus atrophy was associated with an increased likelihood of the presence of US-ESEM, whereas the presence of gallstones was associated with an increased likelihood of the presence of SS-ESEM, suggesting difference in etiology between US- and SS-ESEM.
