Helicobacter pylori infection found during upper endoscopy performed for the diagnosis of celiac, inflammatory bowel diseases, and eosinophilic esophagitis: A multicenter pediatric European study. Helicobacter 2024; 29:e13092. [PMID: 38790089 DOI: 10.1111/hel.13092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 03/21/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Helicobacter pylori may be found during upper gastrointestinal endoscopy (UGE) performed to diagnose celiac disease (CeD), inflammatory bowel disease (IBD), and eosinophilic esophagitis (EoE). We aimed to describe the frequency of H. pylori in children undergoing UGE for CeD, IBD, and EoE and the number of children receiving eradication treatment. MATERIALS AND METHODS A retrospective multicenter study from 14 countries included pediatric patients diagnosed with CeD, IBD, and EoE between January 2019 and December 2021. DATA COLLECTED age, gender, hematologic parameters, endoscopic, histologic, and H. pylori culture results, and information on eradication treatment. RESULTS H. pylori was identified in 349/3890 (9%) children [167 (48%) male, median 12 years (interquartile range 8.1-14.6)]. H. pylori was present in 10% (173/1733) CeD, 8.5% (110/1292) IBD and 7.6% (66/865) EoE patients (p = NS). The prevalence differed significantly between Europe (Eastern 5.2% (28/536), Southern 3.8% (78/2032), Western 5.6% (28/513)) and the Middle East 26.6% (215/809) [odds ratio (OR) 7.96 95% confidence interval (CI) (6.31-10.1) p < 0.0001]. Eradication treatment was prescribed in 131/349 (37.5%) patients, 34.6% CeD, 35.8% IBD, and 56.1% EoE. Predictors for recommending treatment included erosions/ulcers [OR 6.45 95% CI 3.62-11.47, p < 0.0001] and nodular gastritis [OR 2.25 95% CI 1.33-3.81, p 0.003]. Treatment rates were higher in centers with a low H. pylori prevalence (<20%) [OR 3.36 95% CI 1.47-7.66 p 0.004]. CONCLUSIONS Identifying H. pylori incidentally during UGE performed for the most common gastrointestinal diseases varies significantly among regions but not among diseases. The indications for recommending treatment are not well defined, and less than 40% of children received treatment.

Abstract
This study aim to investigate the diagnostic potential of Raman spectroscopy in comparison with rapid urease test and histopathology in diagnosis of H. pylori infection. A comparative study was conducted at Pathology Laboratory and a total of 94 samples were collected from patients based on Rome IV criteria. Sensitivity, specificity and accuracy of histopathology, rapid urease test and for Raman spectroscopy were investigated. Rapid urease test showed 23 false negative results of H. pylori as compared to Raman spectroscopy and histopathology. We concluded that Raman spectroscopy showed sensitivity (94.5%), accuracy (94.0%) and specificity of (87.5%) in the diagnosis of H. pylori infection. However rapid urease test showed specificity of 92.5% while low sensitivity 75%, and 78% accuracy as compared to Raman spectroscopy and histopathology . This study illustrates the applicability of Raman spectroscopy as a potent innovative detection tool for the molecular detection of H. pylori infection in gastritis.

Pattern of Primary Resistance of Helicobacter pylori to Clarithromycin among Pediatric Patients from North-Eastern Romania. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1752. [PMID: 38002843 PMCID: PMC10670121 DOI: 10.3390/children10111752] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 10/24/2023] [Accepted: 10/26/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND Helicobacter pylori antibiotic resistance has increased worldwide and affects the effectiveness of current therapies. The recommended first-line empiric treatment should be tailored to the local clarithromycin resistance rate. This study aimed to determine the pediatric patient profile and rate of clarithromycin resistance for patients diagnosed with Helicobacter pylori by gastric biopsy. METHODS We studied 84 positive gastric samples for Helicobacter pylori. Positive results were confirmed by a rapid urease test and histopathological examination, with the type of gastritis established according to the Sydney System. Gastric biopsy samples were stored in RNA saver. Clarithromycin resistance was determined by a real-time polymerase chain reaction-based molecular assay after RNA-DNA extraction. RESULTS Of the 84 biopsy samples analyzed, 35 (41.6%) were resistant to clarithromycin. Clarithromycin resistance was found mainly in girls (80%) with a mean age of 15 years (range 6-17 years). The history of prior exposure to clarithromycin was 91.6%. The concordance between the histopathological examination and the PCR test was 100%. CONCLUSIONS One in 2.4 children infected with Helicobacter pylori had a strain resistant to clarithromycin. This resistant strain may be a reason for treatment failure in Romanian children, yet this is uninvestigated. The high rate of bacterial resistance to this antibiotic among children indicates the need for susceptibility testing before therapy.

Abstract
In the context of epidemiology, host response, disease presentation, diagnosis, and treatment management, the manifestation of Helicobacter pylori (H. pylori) infection diverges between children and adults. H. pylori infection stands out as one of the most prevalent bacterial infections globally, and its prevalence in both children and adults is decreasing in many developing countries but some still struggle with a high prevalence of pediatric H. pylori infection and its consequences. The majority of infected children are asymptomatic and pediatric studies do not support the involvement of H. pylori in functional disorders such as recurrent abdominal pain. The pathophysiology of H. pylori infection relies on complex bacterial virulence mechanisms and their interaction with the host immune system and environmental factors. This interaction gives rise to diverse gastritis phenotypes, which subsequently influence the potential development of various gastroduodenal pathologies. In clinical settings, the diagnosis of this infection in childhood requires an upper gastrointestinal endoscopic exam with mucosal biopsy samples for histology and culture, or Polymerase Chain Reaction (PCR) at the very least. When warranted, eradication treatment should be given when good compliance is expected, and there should be systematic use of a treatment adapted to the antimicrobial susceptibility profile. To combat the burgeoning threat of multidrug resistance, vigilant surveillance of resistance patterns and strategic antibiotic management are paramount.

Abstract
INTRODUCTION Gastric intestinal metaplasia (GIM) is defined as the replacement of the normal gastric epithelium by intestinal-type epithelium. GIM is considered a preneoplastic lesion for gastric adenocarcinoma in adults and is found in 25% of Helicobacter pylori ( H pylori ) exposed adults. However, the significance of GIM in pediatric gastric biopsies is still unknown. METHODS We conducted a retrospective study of children with GIM on gastric biopsies at Boston Children's Hospital between January 2013 and July 2019. Demographic, clinical, endoscopic, and histologic data were collected and compared to age and sex-matched cohort without GIM. Gastric biopsies were reviewed by the study pathologist. GIM was classified as complete/incomplete based on Paneth cell presence or absence and limited/extensive based on its distribution in the antrum or both antrum and corpus. RESULTS Of 38 patients with GIM, 18 were male (47%), mean age of detection was 12.5 ± 5.05 years (range, 1-18 years). The most common histologic was chronic gastritis (47%). Complete GIM was present in 50% (19/38) and limited GIM was present in 92% (22/24). H pylori was positive in 2 patients. Two patients had persistent GIM on repeat esophagogastroduodenoscopy (2/12). No dysplasia or carcinoma was identified. Proton-pump inhibitor use and chronic gastritis were more common in GIM patients compared to control ( P = 0.02). CONCLUSION Most children with GIM had low-risk histologic subtype (complete/limited) for gastric cancer; GIM was rarely associated with H pylori gastritis in our cohort. Larger multicenter studies are needed to better understand outcomes and risk factors in children with GIM.

Abstract
BACKGROUND Infesting nearly half of the world's population, Helicobacter pylori is thought to cause peptic ulcers and gastric adenocarcinoma. Several studies have examined the association between H. pylori and socioeconomic, clinical, and histological factors in pediatric populations. Similarly, this study aimed to describe the characteristics of H. pylori infection in Moroccan children. METHODS Patients aged 1-17 years who underwent upper gastrointestinal endoscopy over a period of two years from January 2019 to January 2021 were included in this study. Gastric biopsies from the antrum and corpus of the stomach were collected. Detection of H. pylori infection was confirmed by Giemsa stain. Demographic data and clinical and endoscopic characteristics were collected and histopathological findings with gastritis scoring were recorded according to the Sydney System. RESULTS In 213 children, 95 (45%) were found to be infected with H. pylori, and the infection rates increased as the children aged. While no significant relationship between the infection of H. pylori and all symptoms was founded, a significant association was found in nodular gastritis (p<0.05), and 98% of the infected children had chronic inflammation, which was active in 22% and atrophic in 47%. The atrophy and activity were absent or mild, and the inflammation was mild to moderate. CONCLUSION According to this study, nodular gastritis and nonspecific symptoms were related to H. pylori infection in Moroccan children. In addition, the association between this disease and gastric atrophy in our study needs the monitoring of the mucosa of Moroccan children with gastritis and identifying factors that may contribute to gastric cancer.

Usefulness of Molecular Methods for Helicobacter pylori Detection in Pediatric Patients and Their Correlation with Histopathological Sydney Classification. Int J Mol Sci 2022; 24:ijms24010179. [PMID: 36613620 PMCID: PMC9820059 DOI: 10.3390/ijms24010179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 12/14/2022] [Accepted: 12/17/2022] [Indexed: 12/24/2022] Open
Abstract
Helicobacter pylori infections, as one of the most prevalent among humans, are generally acquired during childhood, and are one of the main causes of chronic gastritis and peptic ulcer disease. A bacterial culture from a gastric biopsy is the gold standard and is the only method that has 100% specificity. However, its sensitivity varies, depending on experience of the laboratory staff, applied culture media, specimen transport conditions, biopsy site, and quality of the sample. The same factors compromise all invasive methods and a culture-based H. pylori infection diagnostic, as well as a recent intake of antibiotics, bismuth-containing compounds, and proton pump inhibitors. Molecular methods have been used for clinical microbiology investigation since the beginning of the 21st century. However, their usefulness for H. pylori infections diagnosis remains unclear, especially in pediatric patients. The aim of the study was to assess the incidence of H. pylori infections in a group of 104 pediatric patients and to compare the results of the PCR test with the corresponding histopathological investigation effects. Among the biopsy samples collected from 104 children, 44 (42.3%) were positive in PCR, while 43 (41.3%) and 39 (37.5%) presented histologically-confirmed signs of inflammation and H. pylori colonization, respectively. Moreover, the mean grades of the parameters of the histopathological examination were higher in the group of PCR-positive samples. The compatibility of both research methods was confirmed, emphasizing the usefulness of molecular methods for detecting H. pylori infections in pediatric patients. Considering that the PCR-based method gives reliable results and is less time-consuming and costly, it is worth discussing this method as a new standard in the diagnosis of H. pylori infections, at least among pediatric patients, for which culture-based diagnostics is not sufficient or histopathological examination is negative, while inflammation signs are observed macroscopically.

Abstract
Many reports have shown that patients with Hp-associated chronic gastritis exhibit anxiety and poor sleep quality. However, less is known about the effects and specific manifestations of Hp-associated chronic gastritis on autonomous activity and sleep quality in animals. Here, we investigated the effect of Helicobacter pylori (Hp)-associated chronic gastritis on autonomous activity and sleep quality in mice. To do this, a Hp-associated chronic gastritis mouse model was first established, then analyzed for autonomous activity, relative to controls, for 15 min using an autonomous activity tester. Next, sleep quality of mice was detected by sodium pentobarbital-induced sleep experiment and results compared between groups. The results showed that male mice in the model group exhibited higher activity counts but lower forelimb lift counts, relative to those in the control group, although there were no significant differences (all p > .05). Conversely, female mice in the model group recorded lower activity counts, albeit at no significant difference (p > .05), and significantly lower counts of forelimb lift (p < .05), relative to those in the control group. Notably, male mice in the model group had longer sleep latency and shorter sleep duration than those in the control group, albeit at no significant differences (all p > .05). On the other hand, female mice in the model group recorded significantly longer sleep latency as well as shorter sleep duration compared to those in the control group (all p < .01). We conclude that Hp-associated chronic gastritis exerts certain effects on autonomous activity and sleep quality of mice in a gender-dependent manner. Notably, female mice with Hp-associated chronic gastritis had lower activity and forelimb lift counts, as well as prolonged sleep latency, and shortened sleep duration. These effects were all statistically significant except for activity counts.
