Abstract
BACKGROUND Nodular gastritis (NG) is characterized by marked antral lymphoid follicle formation, and is a strong risk factor for diffuse-type gastric cancer in adults. However, it is unknown whether aberrant DNA methylation, which is induced by atrophic gastritis (AG) and is a risk for gastric cancer, is induced by NG. Here, we analyzed methylation induction by NG. METHODS Gastric mucosal samples were obtained from non-cancerous antral tissues of 16 NG and 20 AG patients with gastric cancer and 5 NG and 6 AG patients without, all age- and gender-matched. Genome-wide methylation analysis and expression analysis were conducted by a BeadChip array and RNA-sequencing, respectively. RESULTS Clustering analysis of non-cancerous antral tissues of NG and AG patients with gastric cancer was conducted using methylation levels of 585 promoter CpG islands (CGIs) of methylation-resistant genes, and a large fraction of NG samples formed a cluster with strong methylation induction. Promoter CGIs of CDH1 and DAPK1 tumor-suppressor genes were more methylated in NG than in AG. Notably, methylation levels of these genes were also higher in the antrum of NG patients without cancer. Genes related to lymphoid follicle formation, such as CXCL13/CXCR5 and CXCL12/CXCR4, had higher expression in NG, and genes involved in DNA demethylation TET2 and IDH1, had only half the expression in NG. CONCLUSIONS Severe aberrant methylation, involving multiple tumor-suppressor genes, was induced in the gastric antrum and body of patients with NG, in accordance with their high gastric cancer risk.

Gao C, Zhang G, Zheng J, Zheng Y, Lin W, Xu G, You Y, Li D, Wang W. The value of LCI-based modified Kyoto classification risk scoring system in predicting the risk of early gastric cancer. Scand J Gastroenterol 2024:1-9. [PMID: 38578144 DOI: 10.1080/00365521.2024.2338443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 03/29/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE To study and compare the value of the Kyoto classification risk scoring system and the modified Kyoto classification risk scoring system based on linked color imaging (LCI) in predicting the risk of early gastric cancer. METHODS One hundred and fifty patients with pathologically confirmed non-cardia early gastric cancer by endoscopic LCI and 150 non-gastric cancer patients matched for age and gender were included. Basic patient data and whole gastric endoscopic images under LCI were collected, and the images were scored according to the LCI-based Kyoto classification risk scoring system and the LCI-based modified Kyoto classification risk scoring system. RESULTS Compared with the LCI-based Kyoto classification risk scoring system, the LCI-based modified Kyoto classification risk scoring system had a higher AUC for predicting the risk of early gastric cancer (0.723 vs. 0.784, p = 0.023), with a score of ≥3 being the best cutoff value for predicting the risk of early gastric cancer (sensitivity 61.33%, specificity 86.00%), and scores of 3 to 5 were significantly associated with early gastric carcinogenesis significantly (OR = 9.032, 95% CI: 4.995-16.330, p < 0.001). CONCLUSIONS Compared with the LCI-based Kyoto classification risk scoring system, the LCI-based Kyoto modified classification risk scoring system has a better value for predicting the risk of early gastric cancer, and the score of 3 to 5 is a high-risk factor for the risk of early gastric cancer development, which is more strongly correlated with the risk of early gastric cancer.

World J Gastroenterol 2023; 29:4763-4773. [PMID: 37664152 PMCID: PMC10473921 DOI: 10.3748/wjg.v29.i31.4763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 07/20/2023] [Accepted: 07/28/2023] [Indexed: 08/18/2023] Open
Abstract
BACKGROUND Gastric cancer (GC) incidence based on the endoscopic Kyoto classification of gastritis has not been systematically investigated using time-to-event analysis. AIM To examine GC incidence in an endoscopic surveillance cohort. METHODS This study was retrospectively conducted at the Toyoshima Endoscopy Clinic. Patients who underwent two or more esophagogastroduodenoscopies were enrolled. GC incidence was based on Kyoto classification scores, such as atrophy, intestinal metaplasia (IM), enlarged folds (EFs), nodularity, diffuse redness (DR), and total Kyoto scores. Hazard ratios (HRs) adjusted for age and sex were calculated using a Cox hazard model. RESULTS A total of 6718 patients were enrolled (median age 54.0 years; men 44.2%). During the follow-up period (max 5.02 years; median 2.56 years), GC developed in 34 patients. The average frequency of GCs per year was 0.19%. Kyoto atrophy scores 1 [HR with score 0 as reference: 3.66, 95% confidence interval (CI): 1.06 to 12.61], 2 (11.60, 3.82-35.27), IM score 2 (9.92, 4.37-22.54), EF score 1 (4.03, 1.63-9.96), DR scores 1 (6.22, 2.65-14.56), and 2 (10.01, 3.73-26.86) were associated with GC incidence, whereas nodularity scores were not. The total Kyoto scores of 4 (HR with total Kyoto scores 0-1 as reference: 6.23, 95%CI: 1.93 to 20.13, P = 0.002) and 5-8 (16.45, 6.29-43.03, P < 0.001) were more likely to develop GC, whereas the total Kyoto scores 2-3 were not. The HR of the total Kyoto score for developing GC per 1 rank was 1.75 (95%CI: 1.46 to 2.09, P < 0.001). CONCLUSION A high total Kyoto score (≥ 4) was associated with GC incidence. The endoscopy-based diagnosis of gastritis can stratify GC risk.

Abstract
BACKGROUND Helicobacter pylori is a gastrointestinal pathogen that infects around half of the world's population. H. pylori infection is the most severe known risk factor for gastric cancer (GC), which is the second highest cause of cancer-related deaths globally. We conducted a systematic review and meta-analysis to assess the global prevalence of GC in H. pylori-infected individuals. METHODS We performed a systematic search of the PubMed, Web of Science, and Embase databases for studies of the prevalence of GC in H. pylori-infected individuals published from 1 January 2011 to 20 April 2021. Metaprop package were used to calculate the pooled prevalence with 95% confidence interval. Random-effects model was applied to estimate the pooled prevalence. We also quantified it with the I2 index. Based on the Higgins classification approach, I2 values above 0.7 were determined as high heterogeneity. RESULTS Among 17,438 reports screened, we assessed 1053 full-text articles for eligibility; 149 were included in the final analysis, comprising data from 32 countries. The highest and lowest prevalence was observed in America (pooled prevalence: 18.06%; 95% CI: 16.48 - 19.63; I2: 98.84%) and Africa (pooled prevalence: 9.52%; 95% CI: 5.92 - 13.12; I2: 88.39%). Among individual countries, Japan had the highest pooled prevalence of GC in H. pylori positive patients (Prevalence: 90.90%:95% CI: 83.61-95.14), whereas Sweden had the lowest prevalence (Prevalence: 0.07%; 95% CI: 0.06-0.09). The highest and lowest prevalence was observed in prospective case series (pooled prevalence: 23.13%; 95% CI: 20.41 - 25.85; I2: 97.70%) and retrospective cohort (pooled prevalence: 1.17%; 95% CI: 0.55 - 1.78; I 2: 0.10%). CONCLUSIONS H. pylori infection in GC patients varied between regions in this systematic review and meta-analysis. We observed that large amounts of GCs in developed countries are associated with H. pylori. Using these data, regional initiatives can be taken to prevent and eradicate H. pylori worldwide, thus reducing its complications.

Abstract
After being ingested and entering the human stomach, Helicobacter pylori (H. pylori) adopts several effective strategies to adhere to and colonize the gastric mucosa and move to different regions of the stomach to obtain more nutrients and escape from the harsher environments of the stomach, leading to acute infection and chronic gastritis, which is the basis of malignant gastric tumors. The endoscopic manifestations and pathological features of H. pylori infection are diverse and vary with the duration of infection. In this review, we describe the endoscopic manifestations of each stage of H. pylori gastritis and then reveal the potential mechanisms of bacterial intragastric colonization and migration from the perspective of endoscopists to provide direction for future research on the effective therapy and management of H. pylori infection.

Abstract
This editorial provides an update of the recent evidence on the endoscopy-based Kyoto classification of gastritis, clarifying the shortcomings of the Kyoto classification, and providing prospects for future research, with particular focus on the histological subtypes of gastric cancer (GC) and Helicobacter pylori (H. pylori) infection status. The total Kyoto score is designed to express GC risk on a score ranging from 0 to 8, based on the following five endoscopic findings: Atrophy, intestinal metaplasia (IM), enlarged folds (EF), nodularity, and diffuse redness (DR). The total Kyoto score reflects H. pylori status as follows: 0, ≥ 2, and ≥ 4 indicate a normal stomach, H. pylori-infected gastritis, and gastritis at risk for GC, respectively. Regular arrangement of collecting venules (RAC) predicts non-infection; EF, nodularity, and DR predict current infection; map-like redness (MLR) predicts past infection; and atrophy and IM predict current or past infection. Atrophy, IM, and EF all increase the incidence of H. pylori-infected GC. MLR is a specific risk factor for H. pylori-eradicated GC, while RAC results in less GC. Diffuse-type GC can be induced by active inflammation, which presents as EF, nodularity, and atrophy on endoscopy, as well as neutrophil and mononuclear cell infiltration on histology. In contrast, intestinal-type GC develops via atrophy and IM, and is consistent between endoscopy and histology. However, this GC risk-scoring design needs to be improved.

Abstract
A 16-year-old girl underwent esophagogastroduodenoscopy (EGD) after the detection of Helicobacter pylori (H. pylori) antibodies in her urine during a school health screening, which revealed nodular gastritis (NG). She was diagnosed as having H. pylori infection histologically and by biopsy culture specimens and soon commenced eradication therapy. Eight weeks later, eradication was confirmed by a urea breath test. At the age of 19, however, she was referred to our hospital with epigastralgia and lower back pain. EGD revealed ulcerative lesions with enlarged folds at the greater curvature of the gastric body. Biopsy specimens of the lesions revealed poorly differentiated adenocarcinoma and signet ring cell carcinoma. The cancer was classified as stage IV with pancreatic invasion. Although NG with pangastritis is considered a high-risk factor for diffuse-type gastric carcinoma, the course of NG after eradication remains unknown. Careful histological assessment before eradication by endoscopic biopsy and close follow-up after eradication are therefore recommended, even in young patients.

Abstract
This case documents a previously undescribed presentation of Helicobacter spp. gastritis. An 8-year-old female spayed golden retriever with chronic vomiting was found to have a cluster of multiple, round, well-defined, hypoechoic foci of varying sizes surrounded by gas within the lumen of the stomach on ultrasonographic examination. Further endoscopic examination revealed multiple raised mass-like lesions in the fundus on endoscopic examination. Histopathological findings were consistent with Helicobacter spp. infection. The dog was treated with both amoxicillin 400 mg and clarithromycin 180 mg BID for 21 days and omeprazole 20 mg SID for 34 days. After the treatment, the vomiting and fundic lesions were resolved on ultrasonographic examination. This case represents a novel gross morphologic presentation for Helicobacter spp. gastritis that responded to appropriate therapy and highlights how early intervention with advanced imaging can aid in diagnosis and treatment.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is a spiral-shaped gram-negative bacterium that colonizes the gastric mucosa. It is a common infectious agent in children. In this study, we aim to evaluate the demographic data, and the clinical and histopathological findings of pediatric patients that underwent upper gastrointestinal endoscopy (UGSE) in our clinic. METHODS Between July 2017 and February 2019, 636 patients applied to the Selcuk University Faculty of Medicine, Pediatric Gastroenterology outpatient clinic with complaints of epigastric abdominal pain and/or dyspeptic complaints. Patients who underwent upper gastrointestinal endoscopy were evaluated retrospectively. Data on age, gender, family history of peptic ulcer disease, and family history of H. pylori were recorded. Endoscopic and histopathological findings were collected from medical records. RESULTS 235 (36.9%) of the patients participating in the study were male, and 401 (63.1%) were female. H. pylori infection was detected in 277 (43.6%) patients as a result of histopathological examination of H. Pylori, urea breath tests and H. Pylori antigen tests in the stools of patients are included in the study. Nodular antral gastritis was detected in 282 (44.3%) of our patients endoscopically. H. pylori was detected in 83.7% (n: 236) of the 282 patients with nodular antral gastritis. Nodular antral gastritis was observed to be significantly higher in H. pylori-positive patients than in H. pylori-negative cases (odds ratio (OR), 39.16; 95% confidence interval (CI), 24.88-61.64; p: <0.001). CONCLUSION Nodular antral gastritis is caused by chronic H. pylori infection. It is predicted that early detection of H. pylori infection in children is important and may decrease complications later in life. Our study shows that all the markers evaluated are very good predictors of H. pylori infection. Positive significant association was found between the prevalence of H. pylori infection and nodular antral gastritis.

Abstract
BACKGROUND Nodular gastritis is most often one of the manifestations of Helicobacter pylori (H. pylori) infection, which is a risk factor for gastric cancer. This study aimed to determine if the histological characteristics of nodular gastritis differed across classes of age. METHODS We conducted a retrospective analysis of consecutive patients who had undergone esophagogastroduodenoscopy with multiple mucosal biopsies of the stomach between 2003 and 2019 for evaluation of updated Sydney System scores. We analyzed and compared the histological characteristics of pediatric (≤15 years old), young (16-29 years old), and older (≥30 years old) patients. RESULTS Of the 1321 patients enrolled, 1027 patients (78%) had H. pylori infection, with 214 patients (21%) of them displaying nodular gastritis. Among nodular gastritis patients, mononuclear cell infiltration Sydney System scores in the gastric body were significantly higher in the older group than in the pediatric (p < .001) and young (p < .001) groups. Similar results were seen for neutrophil infiltration scores in the gastric body. To clarify the characteristics of older nodular gastritis, we investigated 1056 older patients (66 with nodular gastritis, 754 with atrophic gastritis, and 236 H. pylori-negative). The scores for mononuclear and neutrophil cell infiltration in the gastric body were significantly higher in nodular gastritis patients than in atrophic gastritis patients (both p < .001) and patients negative for H. pylori (both p < .001). CONCLUSIONS The inflammatory changes in the gastric body in older nodular gastritis patients were more severe as compared with those in pediatric and young nodular gastritis patients in addition to older atrophic gastritis patients.

Clinical features of cardiac nodularity-like appearance induced by Helicobacter pylori infection. World J Gastroenterol 2020; 26:5354-5361. [PMID: 32994693 PMCID: PMC7504245 DOI: 10.3748/wjg.v26.i35.5354] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 05/17/2020] [Accepted: 09/01/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND We have previously reported that Helicobacter pylori (H. pylori)-associated nodular gastritis could occur in both the antrum and the cardia. Cardiac nodularity-like appearance (hereafter, called as cardiac nodularity) had a high predictive accuracy for the diagnosis of H. pylori infection. In the previous study, we included only the patients who were evaluated for H. pylori infection for the first time, and excluded patients with a history of eradication. Therefore, the prevalence and clinical features of cardiac nodularity remains unknown.
AIM To perform this cross-sectional study to explore the characteristics of cardiac nodularity.
METHODS Consecutive patients who underwent esophagogastroduodenoscopy between May, 2017 and August, 2019 in the Toyoshima Endoscopy Clinic were enrolled in this study. We included H. pylori-negative, H. pylori-positive, and H. pylori-eradicated patients, and excluded patients with unclear H. pylori status and eradication failure. H. pylori infection was diagnosed according to serum anti-H. pylori antibody and the urea breath test or histology. Cardiac nodularity was defined as a miliary nodular appearance or the presence of scattered whitish circular small colorations within 2 cm of the esophagogastric junction. Nodularity was visualized as whitish in the narrow-band imaging mode. We collected data on the patients’ baseline characteristics.
RESULTS A total of 1078 patients were finally included. Among H. pylori-negative patients, cardiac nodularity and antral nodularity were recognized in 0.14% each. Among H. pylori-positive patients, cardiac nodularity and antral nodularity were recognized in 54.5% and 29.5%, respectively. Among H. pylori-eradicated patients, cardiac nodularity and antral nodularity were recognized in 4.5% and 0.6%, respectively. The frequency of cardiac nodularity was significantly higher than that of antral nodularity in H. pylori-positive and -eradicated patients. The frequencies of cardiac nodularity and antral nodularity in H. pylori-eradicated patients were significantly lower than those in H. pylori-positive patients (P < 0.001). The patients with cardiac nodularity were significantly younger than those without cardiac nodularity (P = 0.0013). Intestinal metaplasia score of the patients with cardiac nodularity were significantly lower than those without cardiac nodularity (P = 0.0216). Among H. pylori-eradicated patients, the patients with cardiac nodularity underwent eradication significantly more recently compared with those without cardiac nodularity (P < 0.0001).
CONCLUSION This report outlines the prevalence and clinical features of cardiac nodularity, and confirm its close association with active H. pylori infection.

Abstract
The ABC method combined with Helicobacter pylori antibody and serum pepsinogen is a useful predictive method for stomach cancer. Kyoto classification is a new grading system for endoscopic gastritis. However, the consistency of the Kyoto score with the ABC method remains unclear. The Kyoto classification score, which ranges from 0 to 8, is based on the following findings: atrophy, intestinal metaplasia, diffuse redness, nodularity, and enlarged folds. Furthermore, we defined a simplified Kyoto classification score as the sum of scores of just atrophy and intestinal metaplasia. The association between the Kyoto classification score and the ABC method was analyzed using the Kruskal-Wallis and Steel-Dwass tests. A total of 307 subjects were enrolled. Kyoto classification scores were similar in groups B, C, and D, while scores in group A were significantly lower than those of the other groups. The simplified Kyoto classification score showed the same stepwise increase as the classification of the ABC method. In conclusion, unlike the Kyoto classification score, the simplified Kyoto score showed the same significant stepwise increase as the classification of the ABC method.

Abstract
Background and study aims Helicobacter pylori -associated nodular gastritis, which is associated with follicular lymphoid hyperplasia, is mainly recognized in the antrum. However, we have also observed nodularity-like appearance in the cardia. This study aimed to investigate the clinical significance of cardiac nodularity-like appearance in H. pylori -associated gastritis. Patients and methods Patients who underwent esophagogastroduodenoscopy and were evaluated for H. pylori infection for the first time were enrolled. A nodularity-like appearance in the cardia was defined as a miliary nodular appearance or scattered appearances of small circular whitish coloration. H. pylori infection was diagnosed according to serum anti- H. pylori antibody and the urea breath test or histology. Accuracy of the H. pylori infection diagnoses based on nodularity-like appearance were assessed. Results Among 265 patients, 42 patients (15.8 %) were diagnosed as positive for H. pylori . Cardiac nodularity-like appearance and antral nodularity were recognized in 25 and 15 patients, respectively. In accuracy of predicting H. pylori by cardiac nodularity-like appearance, specificity was 0.996, sensitivity was 0.571, positive predictive value was 0.960, negative predictive value was 0.925, and accuracy was 0.928. The sensitivity of cardiac nodularity-like appearance was significantly higher than that of antral nodularity ( P = 0.0284). Conclusions Cardiac nodularity-like appearance had a high accuracy rate for H. pylori infection diagnosis. Cardiac nodularity-like appearance was found more frequently than antral nodularity.

Abstract
Background and Aim Endoscopy‐based Kyoto classification predicts the risk of Helicobacter pylori infection and gastric cancer; however, the change in score following H. pylori eradication remains unknown. We retrospectively compared the Kyoto score before and after H. pylori eradication. Methods H. pylori‐positive patients who underwent baseline esophagogastroduodenoscopy (EGD), successful H. pylori eradication, and surveillance EGD were enrolled. The Kyoto score is a sum of scores for atrophy (Kimura‐Takemoto atrophic‐border classification none or C1: 0, C‐II or C‐III: 1, O‐I to O‐III: 2), intestinal metaplasia (none: 0, antrum: 1, corpus and antrum: 2), enlarged folds (absence: 0, presence: 1), nodularity (absence: 0, presence: 1), and diffuse redness (none: 0, mild: 1, severe: 2) and ranges from 0 to 8. Results Eighty‐three patients (mean age: 54.9 years; 65.1% women) were enrolled. The mean duration from successful eradication to surveillance EGD was 256 days. The Kyoto score significantly decreased from 3.90 to 2.78 following H. pylori eradication (P < 0.001). Scores for endoscopic atrophy (from 1.43 to 1.46, P = 0.638) and endoscopic intestinal metaplasia (from 0.53 to 0.47, P = 0.543) did not change; however, there was significant improvement in the scores for enlarged folds (from 0.14 to 0.00, P = 0.002), nodularity (from 0.18 to 0.04, P = 0.002), and diffuse redness (from 1.61 to 0.82, P < 0.001). Conclusion The Kyoto classification score decreased following H. pylori eradication. A decrease in the scores for enlarged folds, nodularity, and diffuse redness contributed to the decrease in Kyoto score.

Abstract
Recent advances in endoscopic technology allow detailed observation of the gastric mucosa. Today, endoscopy is used in the diagnosis of gastritis to determine the presence/absence of Helicobacter pylori (H. pylori) infection and evaluate gastric cancer risk. In 2013, the Japan Gastroenterological Endoscopy Society advocated the Kyoto classification, a new grading system for endoscopic gastritis. The Kyoto classification organized endoscopic findings related to H. pylori infection. The Kyoto classification score is the sum of scores for five endoscopic findings (atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness with or without regular arrangement of collecting venules) and ranges from 0 to 8. Atrophy, intestinal metaplasia, enlarged folds, and nodularity contribute to gastric cancer risk. Diffuse redness and regular arrangement of collecting venules are related to H. pylori infection status. In subjects without a history of H. pylori eradication, the infection rates in those with Kyoto scores of 0, 1, and ≥ 2 were 1.5%, 45%, and 82%, respectively. A Kyoto classification score of 0 indicates no H. pylori infection. A Kyoto classification score of 2 or more indicates H. pylori infection. Kyoto classification scores of patients with and without gastric cancer were 4.8 and 3.8, respectively. A Kyoto classification score of 4 or more might indicate gastric cancer risk.

Abstract
This review covers recent publications investigating the relationship between Helicobacter pylori infection and gastroesophageal reflux disease, Barrett's esophagus, eosinophilic esophagitis, peptic ulcer disease (PUD), H pylori gastritis, and functional dyspepsia. In the area of gastroesophageal reflux disease, new data suggest that reflux may have a role in the transmission of H pylori infection. In addition to several observational studies, data on alterations in esophageal physiology in patients with H pylori infection are presented. Further evidence for the inverse relationship between H pylori infection and Barrett's esophagus is available in the form of a meta-analysis from the North American Barrett's and Esophageal Carcinoma Consortium. The relationship between H pylori infection and eosinophilic esophagitis remains uncertain. Although new data do not indicate a significantly lower prevalence of H pylori among patients with eosinophilic esophagitis, a meta-analysis showed a 37% reduced risk of eosinophilic esophagitis among H pylori-infected patients. Novel data are presented on the genetic variability of bacterial virulence factors and their relationship with PUD. We also report data on plasma biomarkers, which may detect progression to gastric cancer in H pylori-associated PUD. A new meta-analysis was published, which assessed the risk of PUD in low-dose aspirin users with H pylori infection. Finally, we report on the ongoing attempts to stratify patients with gastritis using endoscopic methods when compared to standard biopsy examination.

Abstract
Background/Aims Chronic atrophic gastritis (CAG) and metaplastic gastritis (MG) are precancerous conditions of Helicobacter pylori (H. pylori)-related gastric cancer. This study aimed to identify the characteristics of nodular gastritis (NG) showing CAG or MG after nodule regression. Methods H. pylori-infected patients with NG were included after upper gastrointestinal endoscopy. Patients were excluded if their latest endoscopy had been performed ≤36 months after the initial diagnosis of NG. Small-granular-type NG was defined as the condition with 1-2 mm regular subepithelial nodules. Large-nodular-type NG was defined as those with 3-4 mm, irregular subepithelial nodules. The endoscopic findings after nodule regression were recorded. Results Among the 97 H. pylori-infected patients with NG, 61 showed nodule regression after a mean follow-up of 73.0±22.0 months. After nodule regression, 16 patients showed a salt-and-pepper appearance and/or transparent submucosal vessels, indicating CAG. Twenty-nine patients showed diffuse irregular elevations and/or whitish plaques, indicating MG. Sixteen patients with other endoscopic findings (14 normal, one erosive gastritis, and one chronic superficial gastritis) showed a higher proportion of H. pylori eradication (12/16, 75.0%) than those in the CAG group (5/16, 31.3%) and MG group (6/29, 20.7%; p=0.001). Patients with small-granular-type NG tended to progress toward CAG (14/27, 51.9%), whereas those with large-nodular-type NG tended to progress toward MG (25/34, 73.5%; p<0.001). Conclusions In patients with a persistent H. pylori infection, NG tended to progress to CAG or MG when the nodules regressed. Small-granular-type NG tended to progress to CAG, whereas large-nodular-type NG tended to progress to MG.
