Abstract
Helicobacter pylori infection is the major risk factor associated with the development of gastric cancer. Currently, administration of standard antibiotic therapy combined with probiotics and postbiotics has gained significant attention in the management of H. pylori infection. In this work, the immunomodulatory effects of Lactobacillus crispatus-derived extracellular vesicles (EVs) and cell-free supernatant (CFS) were investigated on H. pylori-induced inflammatory response in human gastric adenocarcinoma (AGS) cells. L. crispatus-derived EVs were isolated by ultracentrifugation and physically characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Furthermore, the protein content of L. crispatus-derived EVs was also evaluated by SDS-PAGE. Cell viability of AGS cells exposed to varying concentrations of EVs and CFS was assessed by MTT assay. The mRNA expression of IL-1β, IL-6, IL-8, TNF-α, IL-10, and TGF-ß genes was determined by RT-qPCR. ELISA was used for the measurement of IL-8 production in AGS cells. In addition, EVs (50 μg/mL) and CFS modulated the H. pylori-induced inflammation by downregulating the mRNA expression of IL-1β, IL-6, IL-8, and TNF-α, and upregulating the expression of IL-10, and TGF-ß genes in AGS cells. Furthermore, H. pylori-induced IL-8 production was dramatically decreased after treatment with L. crispatus-derived EVs and CFS. In conclusion, our observation suggests for the first time that EVs released by L. crispatus strain RIGLD-1 and its CFS could be recommended as potential therapeutic agents against H. pylori-triggered inflammation.

Abstract
INTRODUCTION Due to irregular antibiotic use, the rate of antibiotic resistance to Helicobacter pylori (H. pylori) is increasing and varies from region to region. Therefore, for the purpose of further clarifying the changes in antibiotic resistance rates nowadays, we conducted a systematic review and meta-analysis to update and assess the 10-year trend of primary H. pylori antibiotic resistance rate to the commonly prescribed antibiotics worldwide. MATERIALS AND METHODS According to the PRISMA statement, we systematically searched electronic databases for studies that assessed rates of H. pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline published from 2013 to 2023. AHRQ was adopted to estimate methodological quality and publication bias in the included studies, and statistical analysis was performed using Stata 17.0. RESULTS We identified 163 studies, comprising 47,002 isolates from 36 countries. The meta-analysis showed that the primary antibiotic resistance rate of H. pylori varied widely among antibiotics. Subgroup analysis showed higher rates of antibiotic resistance in the adult population than in children, and a general trend of increased resistance was observed from 2013 to 2023. There was considerable heterogeneity (I2 > 75%) among all analyses, which may be due to high variability in resistance rates across the global regions. CONCLUSIONS Resistance of H. pylori to antibiotics has reached alarming levels worldwide, which has a great effect on the efficacy of treatment. Local surveillance networks are required to select appropriate eradication regimens for each region.

Abstract
Helicobacter pylori (HP) infections affect approximately one-third of children worldwide. In China, the incidence of HP infection in children ranges from approximately 30% to 60%. In addition to damaging the gastrointestinal tract mucosa, HP infection in children can negatively affect their growth and development, hematology, respiratory and hepatobiliary system, skin, nutritional metabolism, and autoimmune system. However, the rate of HP eradication also fell considerably from the previous rate due to the presence of drug-resistant HP strains and the limited types of antibiotics that can be used in young patients. Vitamin D3 (VitD3) is a steroid hormone that can reduce inflammation in the stomach mucosa induced by HP and can alleviate and eradicate HP through a variety of pathways and mechanisms, including immune regulation and the stimulation of antimicrobial peptide (AMP) secretion and Ca2+ influx, to reestablish lysosomal acidification; thus, these results provide new strategies and ideas for the eradication of drug-resistant HP strains.

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.

Antibiotic resistance and heteroresistance in Helicobacter pylori isolates from symptomatic Vietnamese children: A prospective multicenter study. Helicobacter 2023; 28:e13009. [PMID: 37497797 DOI: 10.1111/hel.13009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 06/26/2023] [Accepted: 07/19/2023] [Indexed: 07/28/2023]
Abstract
BACKGROUND Antibiotic resistance of Helicobacter pylori (H. pylori) is increasing worldwide, with geographical variations, impacting the treatment outcomes. This study assessed the antibiotic resistance patterns of H. pylori in Vietnamese children. MATERIALS AND METHODS Symptomatic children undergoing gastroduodenoscopy at two tertiary Children's Hospitals in Ho Chi Minh City were recruited. Antral and corpus biopsies were obtained and cultured separately. Susceptibility to amoxicillin (AMO), clarithromycin (CLA), metronidazole (MET), levofloxacin (LEV), and tetracycline (TET) was determined using E-test. Polymerase chain reaction was performed on another antral biopsy to detect the urease gene, cytotoxin-associated gene A (cagA), vacuolating cytotoxin A (vacA) genotypes, and 23S rRNA mutations conferring CLA resistance. RESULTS Among 123 enrolled children, a high primary resistance rate was found for CLA (68.5%, 61/89), followed by LEV (55.1%), MET (31.5%), AMO (25.8%), and TET (1.1%). Secondary resistance rates were 82.1% (7/28), 71.4%, 53.6%, and 3.6% for CLA, LEV, MET, and TET, respectively. Multidrug resistance was frequent (67.7%), with common patterns including CLA + LEV (20.3%) and CLA + MTZ + LEV (15.2%). Heteroresistance was detected in eight children (6.5%). The A2143G mutation was detected in 97.5% (119/122) of children. 86.1% of children had positive cagA strains and 27.9% had multiple vacA genotypes. No factor was significantly associated with antibiotic resistance. CONCLUSIONS The alarming rate of antibiotic resistance for H. pylori, especially for CLA, with emerging multi- and hetero-resistant strains, pose a major treatment challenge that precludes CLA use as empirical therapy. Biopsies from both antrum and corpus can improve H. pylori culture, allowing tailored treatment based on antimicrobial susceptibility.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) remains a major cause of gastroduodenal diseases. We aimed to evaluate the burden of this infection, particularly peptic ulcer disease in Vietnamese children. METHODS We enrolled consecutive children referred for esophagogastroduodenoscopy at two tertiary children's hospitals in Ho Chi Minh City, from October 2019 to May 2021. Children treated with proton pump inhibitors during the last two weeks or antibiotics for four weeks, and those having a previous or interventional endoscopy were excluded. H. pylori infection was diagnosed with either a positive culture or positive histopathology combined with a rapid urease test, or with a polymerase chain reaction of the urease gene. The study was approved by the Ethics Committee and written informed consent/assent was obtained. RESULTS Among 336 enrolled children aged 4-16 (mean: 9.1 ± 2.4 years; 55.4% girls), H. pylori infection was positive in 80%. Peptic ulcers were detected in 65 (19%), increasing with age, and 25% with anemia. cagA+ strains were detected at a higher rate in children with ulcers. CONCLUSIONS Prevalence of H. pylori and peptic ulcers is high among symptomatic Vietnamese children. It is crucial to have a program for early detection of H. pylori to reduce ulcer risk and gastric cancer later.

[PMID: 37138564 PMCID: PMC10149923 DOI: 10.3389/fped.2023.1157777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 03/30/2023] [Indexed: 05/05/2023] Open
Abstract
Background Helicobacter pylori (HP) is a major cause of upper digestive tract diseases. However, the relationship between HP infection and 25-hydroxyvitamin D [25(OH)D] levels in children has not been fully elucidated. This study investigated the levels of 25(OH)D in children of different ages and with varying degrees of HP infection and immunological features as well as the correlations between 25(OH)D levels in children infected with HP and their ages and degrees of infection. Materials and methods Ninety-four children who underwent upper digestive endoscopy were divided into an HP-positive group without peptic ulcers (Group A), an HP-positive group with peptic ulcers (Group B) and an HP-negative control group (Group C). The serum levels of 25(OH)D and immunoglobulin and the percentages of lymphocyte subsets were determined. HP colonization, the degree of inflammation, and the degree of activity were further evaluated by HE staining and immunohistochemical staining in gastric mucosal biopsy. Results The 25(OH)D level of the HP-positive groups (50.93 ± 16.51 nmol/L) was significantly lower than that of the HP-negative group (62.89 ± 19.18 nmol/L). The 25(OH)D level of Group B (47.79 ± 14.79 nmol/L) was lower than that of Group A (51.53 ± 17.05 nmol/L) and was significantly lower than that of Group C (62.89 ± 19.18 nmol/L). The 25(OH)D level decreased with increasing age, and there was a significant difference between Group C subjects who were ≤5 years old and those who were aged 6-9 years and ≥10 years. The 25(OH)D level was negatively correlated with HP colonization (r = -0.411, P < 0.01) and the degree of inflammation (r = -0.456, P < 0.01). The percentages of lymphocyte subsets and immunoglobulin levels among Groups A, B and C were not significantly different. Conclusions The 25(OH)D level was negatively correlated with HP colonization and the degree of inflammation. As the age of the children increased, the level of 25(OH)D decreased, and the susceptibility to HP infection increased.

Antibiotic Resistance of Helicobacter pylori in Patients with Peptic Ulcer. Medicina (B Aires) 2022; 59:medicina59010006. [PMID: 36676631 PMCID: PMC9864273 DOI: 10.3390/medicina59010006] [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] [Received: 11/14/2022] [Revised: 12/13/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022] Open
Abstract
Background and Objectives: To determine the antibiotic resistance rate of H. pylori among patients with peptic ulcer. Materials and Methods: A cross-sectional monocentric study was conducted from January to December 2021 among patients aged from 16 years with gastrointestinal symptoms and esophagogastroduodenoscopy. Gastric mucosa biopsies were collected at the edges of the ulcer or at lesion sites for H. pylori culture. Five antibiotics (amoxicillin (AMX), clarithromycin (CLR), metronidazole (MTZ), levofloxacin (LEV), and tetracycline (TET)) were selected for antibiotic susceptibility testing. Results: One hundred and twenty-five patients were included, and the sex ratio was 0.6. Their mean age was 47.3 ± 14.2 years. All of the participants had gastritis, and 24.0% had duodenitis. A total of 21.6% of patients had a duodenal ulcer, and 12.8% had an antral ulcer. A total of 40 specimens have grown in H. pylori culture. The proportion of resistance to AMX, CLR, MTZ, LEV, and TET was 27.5%, 50%, 67.5%, 35%, and 5%, respectively. The proportion of multidrug resistance was 22.5%. The proportion of double resistance to AMX + CLR was 20.0%, AMX + MTZ was 15.0%, AMX + LEV was 2.5%, CLR + MTZ was 32.5%, and TET + MTZ was 5.0%. Conclusions: Our research results show that the treatment with MTX-TET or LVX-AMOX has the highest sensitivity rate. Therefore, practitioners should refer to these regimes to eradicate H. pylori in patients with gastric and duodenal ulcers. The reports on H. pylori eradication from different geographic areas show heterogeneous results. Therefore, continuous monitoring of antibiotic resistance of H. pylori in each population is very important. Having evidence helps clinicians to treat patients most effectively, reduce treatment costs, and limit the rate of antibiotic resistance.

World Journal of Gastroenterology published the most articles on the H. pylori-related GU field, and GUT was the journal with the most cited articles. Yamaoka Y from Japan was the most productive author, and Graham DY from the USA was the most influential author. A keyword and reference analysis showed that the hot topics of research were the mechanism of H. pylori and the treatment of H. pylori-related GU. The keywords that emerged in the recent 5 years were oxidative stress, probiotics, competitive acid blocker, vonoprazan, gut microbiota, and neutrophil-activating protein. Conclusion Over the recent 10 years, research on H. pylori-related GU has generally shown an increasing trend. The treatment and pathogenesis of H. pylori-related GU remain a hot topic of research. The treatment of H. pylori by oxidative stress and competitive acid inhibitor mechanisms, the influence of gastrointestinal flora on H. pylori, probiotic adjuvant therapy of H. pylori-related GU, and the immunoprotective effect of neutrophil activator protein could be popular research directions and trends in the future.

Nhu LTT, Nguyen VL, Tran VD, Tran NA, Nguyen VT. Evaluation of the Antibiotic Resistance Rate of Helicobacter pylori in Peptic Ulcer Patients in Tien Giang Central General Hospital, Tien Giang Province, Vietnam. Open Access Maced J Med Sci 2022.

Abstract
BACKGROUND: Peptic ulcer (PU), trauma on the lining of the stomach and/or small intestine, is among the top five reasons for hospitalization in Tien Giang, a province in the South of Vietnam. Since Helicobacter pylori (HP) is one of the main causes of PU, its features, especially the antibiotic-resistant status, have critical significance in PU treatment.
AIM: This study evaluates the HP infection prevalence, HP antibiotic resistance rate, and its associations with the patients’ sociodemographic characteristics.
MATERIALS AND METHODS: A cross-sectional study was conducted on PU patients in Tien Giang province, Vietnam, from June 2020 to June 2021. The volunteers were tested for HP infection and antibiotic resistance using three methods, where appropriate, including Gram staining, CLO (urease) test, and bacterial culture method.
RESULTS: Among 368 samples, 31.5% had infected with antibiotic-resistant HP. The resistance rates to five antibiotics commonly used in HP treatment, including metronidazole, clarithromycin, tetracycline, levofloxacin, and amoxicillin, were 96.6%, 94.8%, 70.7%, 61.2%, and 53.4%, respectively. The rates of tetracycline and clarithromycin resistance were related to alcohol consumption (t-test, p < 0.05). The HP treatment history was significantly associated with the levofloxacin resistance (t-test, p < 0.05).
CONCLUSIONS: The emergence of antibiotic-resistant HP is a major public health concern in Tien Giang, Vietnam. This issue should be tackled at the national level to avoid the further spread of these multi-drug resistant HP strains.
