Hsieh H, Yang HB, Sheu BS, Yang YJ. Atrophic gastritis in Helicobacter pylori-infected children. Helicobacter 2022; 27:e12885. [PMID: 35306717 DOI: 10.1111/hel.12885] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 02/10/2022] [Accepted: 02/24/2022] [Indexed: 12/16/2022]
Abstract
BACKGROUND Helicobacter pylori infection is the leading cause of peptic ulcer and chronic gastritis and may initiate gastric carcinogenesis following the Correa cascade. Another lineage of metaplasia, spasmolytic peptide-expressing metaplasia (SPEM) has recently been found to be an alternative precursor to gastric cancer. To date, few reports have investigated gastric precancerous lesions among children with H. pylori infection. This study aimed to evaluate the histopathological pattern of H. pylori atrophic gastritis in children and the extent of precancerous lesions. MATERIALS AND METHODS This study enrolled pediatric patients with H. pylori infection from 1998 to 2019. During esophagogastroduodenoscopy examinations, biopsy fragments were collected from the gastric antrum and corpus for rapid urease test, culture, and histology evaluation. The presence and degree of chronic inflammation, activity of gastritis, H. pylori density, atrophy, and intestinal metaplasia (IM) were assessed according to the modified Updated Sydney System. Trefoil factor 2 (TFF2) immunohistochemistry was also performed to assess SPEM in the gastric tissues collected from each case using rabbit anti-human TFF2 antibodies. RESULTS A total of 92 children with H. pylori infection and adequate gastric mucosa biopsies were enrolled. Esophagogastroduodenoscopy showed that 39 (42.4%) had duodenal ulcers, 11 (12.0%) had gastric ulcers, 41 (44.6%) had gastritis, and 1 (1.1%) had negative findings. Mild-to-moderate IM was identified in 4 patients (4.3%). SPEM was found in 8 patients (8.7%) with a significantly higher incidence among female patients (15.8% vs. 8.7%, p = .031). Gastric glandular atrophy presented in 28 patients (30.4%), and high-grade atrophy was more common in female patients (3.2% vs. 1.9%, p = .031). CONCLUSIONS The prevalence rates of atrophic gastritis in the children with H. pylori infection were 30.4% for gastric glandular atrophy, 4.3% for IM and 8.7% for SPEM. SPEM and high-grade atrophy were more common in female patients.

Chinese Consensus Report on Family-Based Helicobacter pylori Infection Control and Management (2021 Edition). Gut 2022; 71:238-253. [PMID: 34836916 PMCID: PMC8762011 DOI: 10.1136/gutjnl-2021-325630] [Citation(s) in RCA: 64] [Impact Index Per Article: 32.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 11/03/2021] [Indexed: 02/05/2023]
Abstract
OBJECTIVE Helicobacter pylori infection is mostly a family-based infectious disease. To facilitate its prevention and management, a national consensus meeting was held to review current evidence and propose strategies for population-wide and family-based H. pylori infection control and management to reduce the related disease burden. METHODS Fifty-seven experts from 41 major universities and institutions in 20 provinces/regions of mainland China were invited to review evidence and modify statements using Delphi process and grading of recommendations assessment, development and evaluation system. The consensus level was defined as ≥80% for agreement on the proposed statements. RESULTS Experts discussed and modified the original 23 statements on family-based H. pylori infection transmission, control and management, and reached consensus on 16 statements. The final report consists of three parts: (1) H. pylori infection and transmission among family members, (2) prevention and management of H. pylori infection in children and elderly people within households, and (3) strategies for prevention and management of H. pylori infection for family members. In addition to the 'test-and-treat' and 'screen-and-treat' strategies, this consensus also introduced a novel third 'family-based H. pylori infection control and management' strategy to prevent its intrafamilial transmission and development of related diseases. CONCLUSION H. pylori is transmissible from person to person, and among family members. A family-based H. pylori prevention and eradication strategy would be a suitable approach to prevent its intra-familial transmission and related diseases. The notion and practice would be beneficial not only for Chinese residents but also valuable as a reference for other highly infected areas.

Abstract
BACKGROUND The aim of this study was to evaluate the standard values for gender- and age-stratified serum pepsinogen (sPG) in Helicobacter pylori (H. pylori) non-infected children and to determine the optimal cut-off values of sPG for predicting H. pylori-infected gastritis in children. METHODS A prospective study for determination of sPG levels was performed in children with epigastric pain who underwent esophagogastroduodenoscopy over the past 16 years. After excluding subjects diagnosed with inflammatory bowel diseases, eosinophilic gastrointestinal disorders, or immunoglobulin A vasculitis, the diagnosis of H. pylori infection was defined by positive tissue culture or concordant-positive results for histology and the rapid urease test. RESULTS A total of 405 subjects were diagnosed as being H. pylori-infected (79) or non-infected (326). In the H. pylori non-infected group, there were no significant differences in sPG levels among age groups; males had higher sPG I and sPG II levels than females. In the H. pylori-infected group, sPG I and sPG II levels were significantly higher and the sPG I/II ratio was lower than those in the non-infected group. In receiver operating characteristics analyses in diagnosing H. pylori infection, the areas under the curves for sPG I, sPG II and sPG I/II ratio were 0.896, 0.980, and 0.946, respectively. The optimal cut-off value of sPG II of ≥9.0 ng/mL was considered positive for H. pylori infection (sensitivity: 92.4%, specificity: 93.9%). CONCLUSIONS The optimal cut-off value of sPG II of ≥9.0 ng/mL may be a good predictor of H. pylori-infected gastritis in children.

Abstract
The Japan Pediatric Helicobacter pylori Study Group published the first guidelines on childhood H. pylori infection in 1997. They were later revised by the Japanese Society for Pediatric Gastroenterology, Hepatology and Nutrition (JSPGHAN). The H. pylori eradication rates, when employing triple therapy with amoxicillin and clarithromycin, currently recommended as the first-line therapy of H. pylori infection in Japan, have substantially decreased, creating an important clinical problem worldwide. In Japanese adults, the "test-and-treat" strategy for H. pylori infection is under consideration as an approach for gastric cancer prevention. However, the combined North American and European pediatric guidelines have rejected such a strategy for asymptomatic children. As risk for gastric cancer development is high in Japan, determining whether the "test-and-treat" strategy can be recommended in children has become an urgent matter. Accordingly, the JSPGHAN has produced a second revision of the H. pylori guidelines, which includes discussion about the issues mentioned above. They consist of 19 clinical questions and 34 statements. An H. pylori culture from gastric biopsies is recommended, not only as a diagnostic test for active infection but for antimicrobial susceptibility testing to optimize eradication therapy. Based upon antimicrobial susceptibility testing of H. pylori strains (especially involving clarithromycin), an eradication regimen including use of the antibiotics to which H. pylori is susceptible is recommended as the first-line therapy against H. pylori-associated diseases. The guidelines recommend against a "test-and-treat" strategy for H. pylori infection for asymptomatic children to protect against the development of gastric cancer because there has been no evidence supporting this strategy.

Abstract
Background The resistance rate of Helicobacter pylori to clarithromycin (CAM) is high among infected children in Japan. Therefore, a new method for detecting CAM-resistant H. pylori using a minimally invasive technique is strongly desired. We aimed to investigate the clinical usefulness of our newly developed nested polymerase chain reaction-quenching probe (Nested PCR-QP) method using stool specimens. Methods We first evaluated our method using a residual solution of the H. pylori stool antigen test for adolescents. Then, we evaluated our method using culture testing for adults. Results Among 57 middle school students with H. pylori, the Nested PCR-QP test results of 53 (90.3%) were able to be analyzed. A total of 28 students had CAM resistance mutations. We found a genetic mutation in 28 students and no mutation in 23 students, and these results were consistent with those of PCR-direct sequencing. In the 23 adults who were diagnosed with H. pylori infection using the rapid urease test and culture testing, we were able to use Nested PCR-QP for analyzing 21 adults who tested positive in the stool H. pylori antigen test. The results obtained for all 21 adults were consistent with those obtained via the drug susceptibility test. Conclusions Our novel method could be useful for non-invasively detecting CAM resistance mutations in H. pylori. This may help select a drug to reduce eradication failure rates against H. pylori.

Abstract
Helicobacter pylori (H. pylori) infects approximately 50% of the world population. The multiple gastrointestinal and extra-gastrointestinal diseases caused by H. pylori infection pose a major healthcare threat to families and societies; it is also a heavy economic and healthcare burden for countries that having high infection rates. Eradication of H. pylori is recommended for all infected individuals. Traditionally, “test and treat” and "screen and treat" strategies are available for various infected populations. However, clinical practice has noticed that these strategies have some shortfalls and may need refinement, mostly due to the fact that they are not easily manageable, and are affected by patient compliance, selection of treatment population and cost-benefit estimations. Furthermore, it is difficult to control infections from the source, therefore, development of additional, compensative strategies are encouraged to solve the above problems and facilitate bacteria eradication. H. pylori infection is a family-based disease, but few studies have been performed in a whole family-based approach to curb its intra-familial transmission and the development of related diseases. In this work, a third, novel whole family-based H. pylori eradication strategy is introduced. This approach screens, identifies, treats and follows up on all H. pylori-infected individuals in entire families to control H. pylori infection among family members, and reduce its long-term complications. This strategy is high-risk population-oriented, and able to reduce H. pylori spread among family members. It also has good patient-family compliance and, importantly, is practical for both high and low H. pylori-infected communities. Future efforts in these areas will be critical to initiate and establish healthcare policies and management strategies to reduce H. pylori-induced disease burden for society.

Abstract
RATIONALE Helicobacter pylori infection causes atrophic gastritis in childhood, but atrophic gastritis due to H pylori infection is extremely rare in infancy. The relationship between H pylori infection and chronic diarrhea without protein leakage remains controversial. PATIENT CONCERNS An 8-month-old male infant presented to our hospital with severe watery diarrhea, erythema, and failure to thrive from approximately 1 month after birth. Blood, stool, esophagogastroduodenoscopy, total colonoscopy, and H pylori urease analysis results were positive, thereby suggesting atrophic gastritis. DIAGNOSES Atrophic gastritis and chronic diarrhea due to H pylori infection. INTERVENTIONS We performed H pylori eradication therapy using triple therapy with vonoprazan (6 mg/kg), amoxicillin (300 mg/d), and clarithromycin (120 mg/kg) for 7 days. OUTCOMES From approximately 1 week after the H pylori eradication therapy, the frequency of defecation had decreased, stool shape had improved, and body weight had gradually increased. LESSONS H pylori infection can cause atrophic gastritis and chronic diarrhea even in infancy. Early eradication therapy for H pylori infection may be useful for prevention of gastric cancer and improvement in growth disorders.

Guidelines for the management of Helicobacter pylori infection in Japan: 2016 Revised Edition. Helicobacter 2019; 24:e12597.

Abstract
BACKGROUND Since "Helicobacter pylori (H. pylori) infection" was set as the indication in the Japanese Society for Helicobacter Research (JSHR) Guidelines 2009, eradication treatment for H. pylori gastritis is covered under insurance since 2013 in Japan, and the number of H. pylori eradication has rapidly increased. Under such circumstances, JSHR has made the third revision to the "Guidelines for diagnosis and treatment of H. pylori infection" for the first time in 7 years. METHODS The Guideline Committee held 10 meetings. Articles published between the establishment of the 2009 Guidelines and March 2016 were reviewed and classified according to the evidence level; the statements were revised on the basis of this review. After inviting public comments, the revised statements were finalized using the Delphi method. RESULTS There was no change in the basic policy that H. pylori infectious disease is an indication for eradication. Other diseases presumed to be associated with H. pylori infection were added as indications. Serum pepsinogen level, endoscopic examination, and X-ray examination were added to the diagnostic methods. The effects of 1-week triple therapy consisting of potassium-competitive acid blocker (P-CAB), amoxicillin, and clarithromycin have improved, and high eradication rates can also be expected with proton pump inhibitors (PPI) or P-CAB combined with amoxicillin and metronidazole. If the susceptibility test is not performed, the triple PPI or P-CAB/amoxicillin/metronidazole therapy should be chosen, because the PPI/amoxicillin/metronidazole combination demonstrated a significantly higher eradication rate than PPI/amoxicillin/clarithromycin. In the proposal for gastric cancer prevention, we divided gastric cancer prevention measures by age from adolescent to elderly, who are at an increased gastric cancer risk, and presented measures for gastric cancer prevention primarily based on H. pylori eradication. CONCLUSION We expect the revised guidelines to facilitate appropriate interventions for patients with H. pylori infection and accomplish its eradication and prevention of gastric cancer.

A Helicobacter pylori screening and treatment program to eliminate gastric cancer among junior high school students in Saga Prefecture: a preliminary report. J Gastroenterol 2019; 54:699-707. [PMID: 30770975 DOI: 10.1007/s00535-019-01559-9] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Accepted: 02/07/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND To present the strategies and preliminary findings of the first 3 years after implementing a Helicobacter pylori screening and eradication program to prevent gastric cancer in Saga Prefecture. METHODS A screening and treatment program to eradicate H. pylori from third-grade junior high students was started in Saga Prefecture in 2016, using local governmental grants. Screening was with urinary anti-H. pylori antibody tests, followed by H. pylori stool antigen tests for students who were antibody positive. Those positive on both tests underwent H. pylori eradication by triple therapy based on a potassium-competitive acid blocker. RESULTS From 2016 to 2018, the participation rate was 83.1% and the H. pylori infection rate was 3.1% (660/21,042). The participation rates were higher in 2017 (85.4%) and 2018 (85.9%) compared with 2016 (78.5%) (P < 0.0001), and the infection rate also decreased in a time-dependent manner (2016: 3.6%, 2017: 3.3%, 2018: 2.5%, P = 0.0001). In total, 501 students positive for H. pylori received eradication therapy (85.1% success) and adverse events occurred in 20 of these (4.0%). However, no serious complications occurred. CONCLUSIONS The H. pylori screening and eradication project for school students in Saga Prefecture has started successfully and we have seen both a steady increase in the participation rate and a steady decrease in the infection rate, without major safety concerns.

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

Abstract
Gastric adenocarcinoma is quite rare in children and as a result very little experience has been reported on with regards to clinical presentation, treatment and outcome. We describe the case of a 16-year-old boy presenting with abdominal fullness and poor appetite for 7 d. Sonography showed massive ascites and computed tomography imaging revealed the presence of gastric mucosa thickness with omentum caking. The diagnosis of gastric adenocarcinoma was biopsy-proven endoscopically. Despite gastric adenocarcinoma being quite rare in the pediatric patient population, we should not overlook the possibility of gastric adenocarcinoma when a child presents with distended abdomen and massive ascites.

Abstract
Intestinal metaplasia of the gastric antrum is common in adults with chronic gastritis and occurs in Helicobacter -associated gastritis in children. This study examined the frequency and clinical correlates of intestinal epithelium in 1690 consecutive antral biopsies obtained from children over a 2-year period in a tertiary pediatric care facility. Intestinal epithelium in gastric glands not associated with overlying villi was present in 22 (1.3%) biopsies. These came from 20 patients, 2-17 years of age, none of whom had clinical or histologic evidence of Helicobacter infection or significant chronic gastritis. Eight (40%) had an antral pancreatic rest, 8 had some other localized antral abnormality, and 4 were endoscopically normal. Four additional patients with a pancreatic rest had no intestinal epithelium. Six surgically resected rests and 2 rests found at autopsy were also reviewed. Heterotopic intestinal epithelium was present in 1 of the 2 postmortem specimens but was absent from all 6 surgically resected lesions. No intestinal epithelium was present in 67 antral biopsies with Helicobacter gastritis observed during this same period. Although the intestinal epithelium in these patients could be metaplastic, it more likely represents inadvertent sampling of the gastroduodenal junction induced by a lesion in the distal antrum or a focus of heterotopic epithelium and might best be addressed in the surgical pathology report by a comment to this effect. The distinction from metaplasia is more than semantic, because a diagnosis of intestinal metaplasia can have adverse clinical implications and should be made with caution in a child.

Abstract
A 15-year-old adolescent boy with autosomal recessive agammaglobulinemia underwent endoscopy because of unexplained growth failure and malnutrition. Esophagogastroduodenoscopy revealed antropyloric stenosis, and a biopsy showed an invasive gastric adenocarcinoma. Chronic atrophic corpus gastritis type A and Helicobacter pylori were also identified. Abdominal magnetic resonance imaging confirmed the stenosis resulting from a semicircular intramural tumor without obvious local or distant metastatic spread. Gastrectomy with an extended lymphadenectomy was performed. Esophagoduodenal continuity was restored by an interposed jejunal parallel pouch developed from the first jejunal loop. Oral feeding was supplemented by parenteral nutrition via a Broviac catheter, and the patient is well 4 months later. Several cases of gastric cancer have been reported in children with hereditary agammaglobulinemia. Thus, endoscopy is mandatory in such patients with gastrointestinal symptoms to identify and treat tumors before metastasis occurs. Total gastrectomy, extended lymphadenectomy, and reconstruction using a jejunal reservoir with maintenance of duodenal continuity should be considered.

Abstract
OBJECTIVE To evaluate the efficacy of triple eradication therapy versus symptomatic therapy in children with Helicobacter pylori-associated chronic active gastritis (H pylori-ACAG). STUDY DESIGN Symptomatic patients with H pylori-ACAG (n=31) were randomly assigned into two groups: (1) patients infected with H pylori who were treated with triple eradication therapy (n = 16); and (2) patients infected with H pylori who were treated with symptomatic therapy (n=15). RESULTS After 1 year of follow-up, macroscopic appearance was significantly different in group B (P=.023), and chronic inflammation, H Pylori density, and activity were significantly higher in group B than in group A (P=.022, .007, and .002, respectively); however, we did not find a significant difference in the symptoms comparing both groups (P=.287). After 1 year of follow-up, we observed the persistence of the H pylori infection in all children who had not received eradication treatment. CONCLUSIONS There is no correlation between eradication of H pylori infection and improvement of dyspeptic symptoms. Self-eradication does not occur within 1 year of follow-up. A trend toward a higher rate of chronic inflammation in noneradicated children at 1 year limited the time of our study.

Abstract
INTRODUCTION Helicobacter pylori is a definite risk factor for the development of gastric cancer, especially in the context of corpus-predominant gastritis. The infection is usually acquired in early childhood, implying lifelong exposure to this carcinogen if untreated. Our objective was to analyze the prevalence of H. pylori induced corpus-predominant gastritis in children. MATERIAL AND METHODS We analyzed the results of 265 esophagogastroduodenoscopies (EGD) in children performed between February 2006 and August 2008; 34 endoscopies were excluded (24 with follow-up investigations, 5 with incomplete data, 5 adults). H. pylori gastritis was defined by the presence of H. pylori in histology or by a positive rapid urease test. Grade of inflammation was rated according to the updated Sydney Scoring System. Gastritis was classified as corpus-predominant when the degree of chronic inflammation was higher in the corpus than in the antrum and vice versa for antrum-predominant gastritis. RESULTS Two hundred thirty-one patients (128 female; mean age ± SEM: 10.5 ± 3.5 years) were analyzed. Eighty-four (36%) were H. pylori positive, 147 (64%) patients were negative for H. pylori. In H. pylori positive patients, 39 (46%) patients had pangastritis (one patient with mucosal atrophy, which is regarded as precancerous lesion), 42 (50%) had antrum-predominant gastritis and 3 (4%) had corpus-predominant gastritis. One female patient (15.6 years old) with severe (grade 3) pangastritis had focal mucosal atrophy in both antrum and corpus, but no patient had intestinal metaplasia. CONCLUSIONS Corpus-predominant gastritis develops in H. pylori infected children, while mucosal atrophy and intestinal metaplasia develop later in the course of the infection.

Abstract
The objective of this study was to analyze the histopathological patterns of inflammation, distribution, severity, and degree of gastric mucosa of Helicobacter pylori (Hp)-infected children in Northern Mexico, as well as the correlation between colonization density and inflammation intensity. We carried out a cross-sectional study of gastric biopsies performed on children ranging from 2 to 17 years of age who underwent upper gastrointestinal endoscopy for diverse gastroduodenal disorders. This study includes only children who were found to be Hp carriers, with positive results for tests of Hp antigens in feces and in gastric biopsy studies. We studied 107 patients (age 8.2 ± 3.7 years). In 47.7% of patients, the density of Hp colonization was low; only 21.5% had a marked density. Mononuclear leukocyte infiltration showed a similar distribution. Thirty-seven percent of patients had follicular gastritis. An acute inflammatory response was absent in 65% and mild in 20.6% of patients. When inflammation was present, it was primarily located in the antrum (79%). There were no cases of intestinal metaplasia or atrophy. A link was found between Hp density and age, infiltration by mononuclear cells, the presence of follicular gastritis, and the level of neutrophil infiltration (P = 0.001). Despite the high rates of Hp infection in the region, the histopathological findings in these children were mild and were limited primarily to the antral mucosa. These data indicate the need to study the behavior of this disease in children in diverse study populations to provide localized prevention and treatment strategies.
