Histopathological Findings in Adult Patients With Dyspepsia and Their Association With Helicobacter pylori Infection. Cureus 2023; 15:e50981. [PMID: 38259413 PMCID: PMC10801451 DOI: 10.7759/cureus.50981] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/22/2023] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND Helicobacter pylori infection is prevalent among Saudi adults and has been linked to gastric cancer and other tumor-like conditions. We aimed to explore the pathological characteristics of endoscopic gastric biopsies among symptomatic adult Saudi patients and their relation to H. pylori infection. RESULTS Among 151 gastric biopsies, gastritis was detected in 97 (64.2%) cases, chronic active gastritis in 26 patients (17.2%), duodenitis in 20 (13.2%) patients, and total metaplasia in 14 (9.3%) patients. H. pylori was detected in 83 cases (55%), with a recurrence or reinfection rate of 9.8%. The patients with H. pylori infection were considerably young (median age: 34 (IQR: 15) vs. 35.5 (IQR: 11), p = 0.024) and had a low frequency of epigastric pain (78.3% vs. 91.2%, p = 0.031), reflux/regurgitation (7.2% vs. 20.6%, p = 0.016), and dysphagia (4.85% vs. 14.7%, p = 0.037). However, they exhibited a higher incidence of chronic active gastritis (96.2% vs. 3.8%, p < 0.001) and intestinal metaplasia (85.7% vs. 14.3%, p = 0.015). Young age (OR = 1.09, 95% CI = 1.02-1.16, p = 0.011) and H. pylori infection (OR = 30.85, 95% CI = 3.26-291.60, p = 0.003) were identified as a positive predictor of intestinal metaplasia while heartburn (OR = 0.08, 95% CI = 0.01-0.58, p = 0.012) was a negative predictor. CONCLUSION H. pylori infection is prevalent among Saudi adults experiencing upper gastrointestinal symptoms and is associated with intestinal metaplasia. Infection rate and intestinal metaplasia were higher in patients with milder symptoms. Therefore, screening for H. pylori is highly recommended for Saudi individuals with upper gastrointestinal symptoms. Old age and H. pylori infection were identified as positive predictors of intestinal metaplasia, emphasizing the importance of early detection and management of H. pylori infection in the Saudi population.

The global prevalence of gastric cancer in Helicobacter pylori-infected individuals: a systematic review and meta-analysis. BMC Infect Dis 2023; 23:543. [PMID: 37598157 PMCID: PMC10439572 DOI: 10.1186/s12879-023-08504-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 07/31/2023] [Indexed: 08/21/2023] Open
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.

Serum pepsinogens as a gastric cancer and gastritis biomarker in South and Southeast Asian populations. PLoS One 2020; 15:e0230064.

Abstract
Serum pepsinogens have been widely acknowledged as gastric mucosal biomarkers; however, a multicountry report on the benefits of pepsinogens as biomarkers has not yet been published. We analyzed 1,206 sera and gastric mucosal samples collected from Bangladesh, Bhutan, Indonesia, Myanmar, Nepal and Thailand then assessed the association between gastric mucosal changes and Helicobacter pylori infection. The new cutoff values for serum pepsinogen values were evaluated using a receiver operating characteristic analysis. The participants with H. pylori infection had significantly lower pepsinogen I and higher pepsinogen II values, but a lower pepsinogen I/II ratio than participants without the infection (all P < .001). The pepsinogen I and pepsinogen I/II values were significantly higher and lower, respectively, in individuals with atrophic gastritis than in those without (both P < .001). Among uninfected individuals, only the pepsinogen I/II ratio was significantly lower in atrophic individuals. Pepsinogen I/II ratio also were significantly different between disease among H. pylori-positive and H. pylori-negative individuals, suggesting the pepsinogen I/II ratio is a robust biomarker for determining both chronic and atrophic gastritis. The cutoffs for detecting chronic and atrophic gastritis for the pepsinogen I/II ratio were 4.65 and 4.95, respectively. In conclusion, pepsinogen levels are useful biomarker for both chronic gastritis and atrophic gastritis, but they should be used with caution. Population-based validation is necessary to determine the best cutoff values. Among all pepsinogen values, the pepsinogen I/II ratio was the most reliable gastric mucosal-change biomarker.

Abstract
Indonesia is a big country with multiethnic populations whose gastric cancer risks have not been elucidated. We performed a nationwide survey and obtained histological specimens from 1053 individuals in 19 cities across the country. We examined the gastric mucosa, the topography, the atrophic gastritis risk factors, and the gastric cancer risk scores. Almost half (46.1%) of the patients with dyspeptic symptoms had histological abnormalities; chronic (36.3%) and atrophic gastritis (28.9%) being the most frequent. Individuals of the Timor ethnicity had the highest prevalence of acute (52.6%) and chronic gastritis (68.4%), even those negative for H. pylori. Our topographic analysis showed the majority of patients had predominantly antral acute and chronic gastritis. A multivariate logistic regression model showed age (Odds ratio [OR], 1.107), Timor ethnicity (OR, 8.531), and H. pylori infection (OR, 22.643) as independent risk factors for presence of atrophic gastritis. In addition, the gastric cancer risk score was highest in those from Timor, Papuan, and Bugis ethnic populations. Overall, Indonesia is a low-risk gastric cancer country. However, several ethnic groups displayed severe gastric mucosa symptoms suggesting policy makers should focus on those ethnic groups to perform gastric cancer screenings and to eradicate H. pylori.

Accuracy of diagnostic demarcation of undifferentiated-type early gastric cancers for magnifying endoscopy with narrow-band imaging: endoscopic submucosal dissection cases. Gastric Cancer 2016; 19:515-523. [PMID: 25744291 DOI: 10.1007/s10120-015-0488-x] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2015] [Accepted: 02/24/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND The usefulness of magnifying endoscopy with narrow-band imaging (ME-NBI) for undifferentiated-type early gastric cancers (UD-type EGCs) is unclear. The present study examined the accuracy of the diagnostic demarcation of lesions using ME-NBI. METHODS The study population consisted of 76 patients with UD-type EGC lesions measuring ≤20 mm in diameter using white-light imaging (WLI) and endoscopic ultrasonography and diagnosed as intramucosa and UL(-); all the lesions were confirmed as early gastric cancer based on postoperative pathological examination. All the patients had undergone an initial endoscopic submucosal dissection (ESD) at this hospital between January 2010 and January 2014. After marking with demarcation lines at the utmost oral and anal sites of the lesion using argon plasma coagulation under ME-NBI for intervention, the cases with demarcations that were consistent with the postoperative pathological findings were defined as having been accurately diagnosed. The inflammatory cell infiltration (Updated Sydney System, USS) were also assessed. RESULTS The diagnostic demarcations of the lesion were consistent in 62 cases (81.6 %). The accurate diagnosis rate was higher for the USS cases with mild neutrophil and monocyte infiltration (P < 0.05). The addition of ME-NBI to WLI improved the accurate diagnosis rate by 27.6 %. CONCLUSION The use of ME-NBI in diagnostic demarcation of UD-type EGCs is recommended.

Abstract
BACKGROUND The differences in the growth morphology, proliferative ability, and background mucosa of the cancer between Helicobacter pylori (HP)-positive (HP+) gastric cancer (GC) and HP-negative (HP-) GC are still unclear. To clarify the differences, we compared the characteristics of the two types of cancer. METHODS Of the 91 patients with undifferentiated-type early GC who underwent endoscopic treatment at our hospital between August 2005 and April 2011, 23 HP- GC patients (all of whom had signet ring cell carcinoma measuring 20 mm or less in diameter) and 46 HP+ GC patients with signet ring cell carcinoma measuring 20 mm or less in diameter (out of a total of 68 HP+ GC patients) were enrolled in this study. Endoscopic atrophy and background mucosa were classified according to the updated Sydney system. The proliferative capacity of the cancer was assessed by examining the MIB-1 labeling index. RESULTS With regard to the growth in the mucosal layer, the proportion of patients with cancer confined to the proliferative zone was significantly higher in the HP- GC group. Moderate or severer atrophy, intestinal metaplasia, mononuclear cell infiltration, and neutrophil infiltration according to the updated Sydney system were significantly commoner in the HP+ GC patients. Also, the MIB-1 labeling index was significantly higher in the HP+ GC group. CONCLUSION HP+ GC appeared to show a higher proliferative capacity, more extensive spread, and more rapid progression, and inflammation associated with HP infection was suggested to be involved in the proliferation of this type of GC.

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
BACKGROUND The relationship between Helicobacter pylori infection and gastric cancer has been demonstrated, and the risk of gastric cancer occurrence is known to increase with the progression of atrophic changes associated with chronic gastritis. Endoscopic evaluation of the degree and extent of atrophy of the gastric mucosa is a simple and very important means of identifying a group at high risk for gastric cancer. This study aimed to clarify the carcinogenic risk in relation to the degree of atrophy. METHODS A total of 27,777 patients (272 with early gastric cancer and 135 with advanced gastric cancer) were included in this study. Endoscopically evaluated atrophy of the gastric mucosa was classified as C-0 to O-3 according to the Kimura and Takemoto classification system. RESULTS The cancer detection rate in relation to the degree of gastric mucosal atrophy was 0.04% (2/4,183 patients) for C-0, 0% (0/4,506) for C-1, 0.25% (9/3,660) for C-2, 0.71% (21/2,960) for C-3, 1.32% (75/5,684) for O-1, 3.70% (140/3,780) for O-2 and 5.33% (160/3,004) for O-3. As to the proportions of differentiated and undifferentiated cancers, the latter were relatively frequent in the C-0 to C-2 groups, but differentiated cancers became predominant as atrophy progressed. On the other hand, the number of both differentiated and undifferentiated cancers detected increased as gastric mucosal atrophy progressed. In addition, open-type atrophy was found in 29 (96.7%) of 30 patients with synchronous multiple gastric cancers and in all 20 patients with metachronous multiple gastric cancers. CONCLUSION Endoscopic evaluation of gastric mucosal atrophy can provide a simple and reliable predictive index for both current and future carcinogenic risk.

Abstract
BACKGROUND AND AIM Gastric atrophy is one of the important pathological states that cause gastric cancer. As atrophic gastritis is related to the risk of gastric cancer, it is important to diagnose atrophic gastritis. In the present study, we tried to establish endoscopic criteria for atrophic gastritis. METHODS A multicenter study of prospectively collected patients was conducted in 24 participating facilities. Two hundred and seventy-five patients received endoscopic examination and 15 endoscopic features, including diffuse redness, swelling of areae gastrica, and mucosal swelling, were evaluated. Biopsy specimens were taken from five points recommended by the Updated Sydney System, and evaluated by a single pathologist for atrophy. Sensitivity, specificity, positive predictive value, negative predictive value, area under the receiver operating characteristic curve (AUC/ROC) of each endoscopic finding to histological atrophy were calculated. Pepsinogen I/II ratios of these patients were measured and compared to the endoscopic features. RESULTS There was no single endoscopic feature that is highly specific for histological atrophy. In the corpus, the combination of visibility of vascular pattern and swelling of areae gastrica by indigocarmine chromoendoscopy showed the highest AUC/ROC (0.83). In the antrum, the combination of visibility of vascular pattern and mucosal swelling showed the highest AUC/ROC (0.70). These endoscopic findings correlated very well to the pepsinogen I/II ratio. CONCLUSIONS Combination of endoscopic findings can improve diagnostic accuracy, and endoscopic diagnosis of atrophy is improved especially with new endoscopic criteria, such as swelling of areae gastrica or mucosal swelling.

Abstract
BACKGROUND/AIM Severity of chronic gastritis associated with Helicobacter pylori infection (CGAHpI) could play a role in evaluating the potential risk to develop gastric cancer. Our aim was to estimate the risk for gastric cancer in a clinical setting, according to histopathologic criteria, by applying the gastric cancer risk index (GCRI) METHODS: Histopathologic study of the gastric biopsies (corpus-antrum) from consecutive adult patients that underwent gastroesophageal duodenoscopy was carried out, and the GCRI was applied in patients presenting with CGAHpI. RESULTS One hundred eleven patients (77% female) with a mean age of 38.6±13.1 years were included. Active Helicobacter pylori infection (aHpi) was diagnosed in 77 cases (69.40%). In 45% of the cases with aHpi, pangastritis (23%) or corpus-predominant gastritis (22%) was diagnosed. Nine cases were diagnosed with intestinal metaplasia (8%), 7 of which (77.70%) were in the aHpi group. Twenty one percent of the patients with aHpi had a GCRI of 2 (18.10%) or 3 (2.50%) points (high risk index), while 79.10% accumulated a GCRI of 0 or 1 points (low risk index). Of the patients with no aHpi, none of them had 3 points (p=0.001). Of the 18 patients that accumulated 2 or 3 points, 6 (33.30%) presented with intestinal metaplasia (all with pangastritis and corpus-predominant gastritis), of which 4 cases (66.60%) had aHpi. CONCLUSIONS The estimated gastric cancer risk in patients with CGAHpI in the clinical setting studied was relatively low and 5% of the patients had a histopathologic phenotype associated with an elevated risk for developing gastric cancer.

Abstract
AIM Gastritis is an important pathological state that causes gastric atrophy and cancer. The Sydney System is a well-used classification for histological evaluation for gastritis. However, there is no concordance with endoscopic findings. In the present study, we tried to establish endoscopic criteria and diagnosis for the inflammation activity of gastric mucosa. METHODS A prospective multicenter study was conducted and 24 facilities participated. Two hundred and seventy patients received endoscopic examinations and 15 endoscopic features were evaluated. Biopsy specimens were taken from five points, and evaluated by a single pathologist for mononuclear cell infiltration and polymorphonuclear cell infiltration. Sensitivity, specificity, positive predictive value, negative predictive value, area under curve of receiver operating characteristics (AUC/ROC) of each endoscopic finding to histological gastritis were calculated. RESULTS There was no single endoscopic finding that was highly specific for mononuclear cell infiltration and polymorphonuclear cell infiltration. In the corpus, the combination of swelling of areae gastrica by the indigo carmine contrast method (IC method) and lack of a regular arrangement of collecting venules (RAC) in angle for mononuclear cell infiltration (0.887), and the combination of swelling of areae gastrica by the IC method and diffuse redness for polymorphonuclear cell infiltration (0.851) showed the highest AUC/ROC. In the antrum, the combination of diffuse redness and visibility of a vascular pattern for mononuclear cell infiltration (0.780), and the combination of visibility of vascular pattern and swelling of areae gastrica by the IC method for polymorphonuclear cell infiltration (0.795) showed the highest AUC/ROC. CONCLUSION Combination of endoscopic findings can improve diagnostic accuracy, and sensitivity of examination for inflammation.
