Virulence gene polymorphisms in Shandong Helicobacter pylori strains and their relevance to gastric cancer. PLoS One 2024; 19:e0309844. [PMID: 39250512 PMCID: PMC11383249 DOI: 10.1371/journal.pone.0309844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 08/20/2024] [Indexed: 09/11/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) virulence factors, particularly the cagA and vacA genotypes, play important roles in the pathogenic process of gastrointestinal disease. METHODS The cagA and vacA genotypes of 87 H. pylori strains were determined by PCR and sequencing. The EPIYA and CM motif patterns were analyzed and related to clinical outcomes. We examined the associations between the virulence genes of H. pylori and gastrointestinal diseases in Shandong, and the results were analyzed via the chi-square test and logistic regression model. RESULTS Overall, 76 (87.36%) of the strains carried the East Asian-type CagA, with the ABD types being the most prevalent (90.79%). However, no significant differences were observed among the different clinical outcomes. The analysis of CagA sequence types revealed 8 distinct types, encompassing 250 EPIYA motifs, including 4 types of EPIYA or EPIYA-like sequences. Additionally, 28 CM motifs were identified, with the most prevalent patterns being E (66.67%), D (16.09%), and W-W (5.75%). Notably, a significant association was discovered between strains with GC and the CM motif pattern D (P < 0.01). With respect to the vacA genotypes, the strains were identified as s1, s2, m1, m2, i1, i2, d1, d2, c1, and c2 in 87 (100%), 0 (0), 26 (29.89%), 61 (70.11%), 73 (83.91%), 14 (16.09%), 76 (87.36%), 11 (12.64%), 18 (20.69%), and 69 (79.31%), respectively. Specifically, the vacA m1 and c1 genotypes presented a significantly greater prevalence in strains from GC compared to CG (P < 0.05). Following adjustment for age and sex, the vacA c1 genotype demonstrated a notable association with GC (OR = 5.174; 95% CI, 1.402-20.810; P = 0.012). This association was both independent of and more pronounced than the correlations between vacA m1 and GC. CONCLUSIONS CagA proteins possessing CM motif pattern D were more frequently observed in patients with GC (P < 0.01), implying a potentially higher virulence of CM motif pattern D than the other CM motif patterns. Moreover, a strong positive association was identified between the vacA c1 genotype and GC, indicating that the vacA c1 genotype is a robust risk indicator for GC among male patients aged ≥55 years in Shandong.

Alamri ZZ. Apigenin attenuates indomethacin-induced gastric ulcer in rats: emphasis on antioxidant, anti-inflammatory, anti-apoptotic, and TGF-β1 enhancing activities. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024:10.1007/s00210-024-03200-w. [PMID: 38842560 DOI: 10.1007/s00210-024-03200-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 05/29/2024] [Indexed: 06/07/2024]
Abstract
Gastric ulcer disease is associated with significant morbidity and mortality rates. The most two common causes of the ulcer are Helicobacter pylori infection and non-steroidal anti-inflammatory drugs. In the past few decades, a significant decrease in the morbidity and mortality rate has been observed probably due to the discovery of proton pump inhibitors. However, the medications used to treat gastric ulcers impose several nauseous side effects. Therefore, recent studies focus on the use of natural products to treat gastric ulcers. In the current study, gastric ulcer was effectively induced using indomethacin, and the protective effect of apigenin, a potent antioxidant flavonoid, was assessed in comparison to omeprazole. The administration of a single oral indomethacin (50 mg/kg) induced gastric ulcer as manifested by hemorrhagic lesions in the gastric mucosa, increased ulcer index, and histopathological alterations. Indomethacin also increased lipid peroxidation, decreased the activities of the antioxidant enzymes superoxide dismutase (SOD) and catalase, increased the immunoreactivity of the inflammatory markers cyclo-oxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB), increased the transcription of the apoptotic marker, Bax, and decreased that of the antiapoptotic Bcl-2. Indomethacin also decreased the immunoreactivity of transforming growth factor-beta 1 (TGF-β1). On the other hand, pretreatment with apigenin (10 and 20 mg/kg) resulted in a dose-dependent improvement in the macroscopic and microscopic features of the gastric mucosa in a manner comparable to that of omeprazole. The gastroprotective effects of apigenin may be attributed to its anti-inflammatory, anti-antioxidant, and anti-apoptotic activities as well as enhancing the expression of TGF-β1. Further experimental and clinical research is required to confirm activity of apigenin as anti-ulcer agent.

Abstract
Areas of the body accessible to gastric secretions, such as the stomach and duodenum, are most commonly damaged by circumscribed lesions of the upper gastrointestinal tract mucosa. Peptic ulcer disease is the term for this illness (PUD). About 80% of peptic ulcers are duodenal ulcers, with stomach ulcers accounting for the remaining 20%. Duodenal ulcers are linked to the two primary results about Helicobacter pylori infection and COX inhibitor users. Additional causes might include drinking, smoking, stress, and coffee consumption. The indications and symptoms of a duodenal ulcer depend on the patient's age and the lesion's location. For duodenal ulcers, proton pump inhibitors (PPIs) are the usual course of treatment. This comprehensive study included an in-depth literature search in the literature and methods section using electronic databases such as PubMed, ScienceDirect, and Google Scholar. The search method included publications published from the inception of the relevant database to the present. Inclusion criteria included studies investigating different treatment options for duodenal ulcer disease, including traditional pharmacotherapy and naturopathic treatments. Data mining includes information on treatment techniques, treatment outcomes, and possible synergies between conventional and herbal treatments. In addition, this review critically examines the available information on the effectiveness, safety, and possible side effects of different treatments. The inclusion of conventional and herbal treatments is intended to provide a comprehensive overview of the many treatment options available for duodenal ulcer disease. A more comprehensive and personalized treatment plan can be achieved by incorporating dietary changes, lifestyle modifications, and, if necessary, herbal therapies to complement other treatments normally.

Abstract
BACKGROUND Peptic ulcer disease (PUD) is a common disease worldwide, especially in developing countries. China, Brazil, and India are among the world's fastest-growing emerging economies. This study aimed to assess long-term trends in PUD mortality and explore the effects of age, period, and cohort in China, Brazil, and India. METHODS We collected data from the 2019 Global Burden of Disease Study and used an age-period-cohort (APC) model to estimate the effects of age, period, and cohort. We also obtained net drift, local drift, longitudinal age curve, and period/cohort rate ratios using the APC model. RESULTS Between 1990 and 2019, the age-standardized mortality rates (ASMRs) of PUD and PUD attributable to smoking showed a downward trend in all countries and both sexes. The local drift values for both sexes of all ages were below zero, and there were obvious sex differences in net drifts between China and India. India had a more pronounced upward trend in the age effects than other countries. The period and cohort effects had a similar declining trend in all countries and both sexes. CONCLUSIONS China, Brazil, and India had an inspiring decrease in the ASMRs of PUD and PUD attributable to smoking and to period and cohort effects during 1990-2019. The decreasing rates of Helicobacter pylori infection and the implementation of tobacco-restricting policies may have contributed to this decrease.

Abstract
Peptic ulcer is one of the most common gastrointestinal tract disorders worldwide, associated with challenges such as refractory morbidity, bleeding, interference with use of anticoagulants, and potential side effects associated with long-term use of proton pump inhibitors. A peptic ulcer is a defect in gastric or duodenal mucosa extending from muscularis mucosa to deeper layers of the stomach wall. In most cases, ulcers respond to standard treatments. However, in some people, peptic ulcer becomes resistant to conventional treatment or recurs after initially successful therapy. Therefore, new and safe treatments, including the use of stem cells, are highly favored for these patients. Adipose-derived mesenchymal stem cells are readily available in large quantities with minimal invasive intervention, and isolation of adipose-derived mesenchymal stromal stem cells (ASC) produces large amounts of stem cells, which are essential for cell-based and restorative therapies. These cells have high flexibility and can differentiate into several types of cells in vitro. This article will investigate the effects and possible mechanisms and signaling pathways of adipose tissue-derived mesenchymal stem cells in patients with refractory peptic ulcers.

Abstract
Based on the antibody typing classification, Helicobacter pylori infection can be divided into type I H. pylori infection and type II H. pylori infection. To observe the effects of different H. pylori infection types on the distribution of histopathological characteristics and the levels of three items of serum gastric function (PG I, PG II, G-17). 1175 cases from October 2018 to February 2020 were collected with ratio 1:2. All patients were performed with 14C-Urea breath test (14C-UBT), H. pylori antibody typing classification, three items of serum gastric function detection, painless gastroscopy, pathological examination, etc. According to H. pylori antibody typing classification, patients were divided into three groups: type I H. pylori infection group, type II H. pylori infection group and control group. Significant difference existed among type I H. pylori infection group, type II H. pylori infection group and control group in inflammation and activity (χ2 = 165.43, 354.88, P all < 0.01). The proportion of three groups in OLGA staging had statistic difference (χ2 = 67.99, P all < 0.01); Compared with type II H. pylori infection group and control group, the level of pepsinogen I, pepsinogen II, gastrin17 in type I H. pylori infection group increased, and PG I/PG II ratio (PG I/PG II ratio, PGR) decreased, which was statistically significant (χ2 = 35.08, 166.24, 134.21, 141.19; P all < 0.01). Type I H. pylori infection worsened the severity of gastric mucosal inflammation and activity. H. pylori infection was prone to induce atrophy of gastric mucosa, while type I H. pylori infection played a key role in promoting the progress of atrophic gastritis and affected the level of serum gastric function. The study indicated that the eradication of H. pylori should be treated individually.

Abstract
BACKGROUND Helicobacter pylori is accounted as the most etiologic agent for digestive disorders, in particular, the most important of them i.e. peptic ulcer and gastric cancer. In the recent years, association of vacA genotypes and gastrointestinal disorders has attracted a lot of attention. In present study, we assessed the correlation between vacA genotypes (s1, s2, m1, m2, s1m1, s1m2, s2m1 and s2m2) and development to peptic ulcer in Iranian population. METHODS In our study, first, 24 original articles containing of information of 3328 patients were evaluated. Statistical analysis was done by Comprehensive Meta-Analysis version 2.0 software (Biostat, Englewood, NJ, USA). In this regards, we used from fixed-effects model for analysis of data with low heterogeneity, while for analysis of data with high heterogeneity (I2 statistic index > 25%, Cochrane Q statistic p value < 0.05), random-effects model was used. RESULTS Abundance of each of s1, s2, m1, m2, s1m1, s1m2, s2m1, and s2m2 was estimated 36.24, 28.32, 42.90 29.86, 27.88, 32.34, 15.70, and 25.94%, respectively. According to the results, the m1, s1, and s1m2 genotypes were among the most prevalent genotypes among the Iranian patients, whereas, s2m1 genotype had the lowest frequency. CONCLUSIONS Overall, 24 articles (total participants = 3328) were included in this comprehensive analysis. H. pylori infection rate were 90.26% in these cases, so that 33.65% of whom had peptic ulcer. Moreover, the abundance of each vacA genotypes including s1, s2, m1, m2, s1m1, s1m2, s2m1, and s2m2 was estimated as 36.24, 28.32, 42.90 29.86, 27.88, 32.34, 15.70, and 25.94% respectively. We demonstrated that there is a significant relationship between infection of stomach with m1, s1m1, and s2m1 genotypes and development to peptic ulcer disease.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is one of the important risk factors of gastric related diseases and antibiotic therapy has become an effective treatment. At present, proton-pump inhibitor and amoxicillin-based triple therapy, including clarithromycin (PAC) and metronidazole (PAM), are two commonly used first-line therapies for H. pylori infection, which has a high incidence and possibly poor prognosis worldwide. METHODS A systematic literature review was performed using the databases PubMed, the Cochrane Library, Ovid Medline, Science Direct, Embase, Scopus and Web of Science. Only randomized clinical trials with full texts published were included. RESULTS Eighteen studies involving 3264 patients were included. The pooled risk ratios (RR) between the PAC and PAM groups were comparable in the intention-to-treat (ITT) eradication rates (71.0% versus 75.2%, RR = 0.96, p = 0.38) and per-protocol (PP) eradication rates (79.6% versus 80.1%, RR = 1.02, p = 0.65). PAM is highly effective in clarithromycin-resistant cases (70.4% versus 48.2%, RR = 0.65, p = 0.002) and that PAC showed significant efficacy in metronidazole-resistant cases (87.3% versus 58.6%, RR = 1.43, p = 0.0006). In subgroup analysis, when using low-dose PPI, the PAM group showed greater efficacy than the PAC group. Furthermore, we found that PAM showed higher effectiveness in the studies published in recent years, especially for people over 60 years old (RR = 0.80, 95% CI: 0.71-0.89, p < 0.001). CONCLUSION In general, both PAC and PAM regimens were effective and comparable in eradicating H. pylori. However, the PAM regimen showed greater efficacy than the PAC regimen in recent years, especially for people over 60 years old.

Protective effects of Aronia melanocarpa juices either alone or combined with extracts from Rosa canina or Alchemilla vulgaris in a rat model of indomethacin-induced gastric ulcers. Food Chem Toxicol 2019; 132:110739.

Abstract
The aim of the study was to investigate the effects of four Aronia melanocarpa-based juices in a rat model of indomethacin-induced gastric ulceration. THE JUICES WERE: AM1 and AM2 (produced from aronia fruits at 20 °C and 60 °C, respectively), AMRC (a mixture of AM2 with Rosa canina extract) and AMAV (aronia juice with Alchemilla vulgaris). Male Wistar rats were used. Each of the juices (10 ml/kg) was administered for 10 days. Indomethacin (30 mg/kg) was injected subcutaneously and after 4 h, the effects were estimated. Indomethacin caused heavy destructions of the gastric mucosa, increased the expression of Bax and decreased the expression of Bcl-2, induced a certain increase in lipid peroxidation and a slight decrease in gastric PGE2 content. The pretreatment with the juices reduced the severity of indomethacin-induced gastric lesions and antagonized the effects of indomethacin on apoptosis and lipid peroxidation. The highest was the protective effect of AMAV, the juice with the highest polyphenolic content. The protective effect of Aronia melanocarpa-based juices against indomethacin-induced gastric lesions could be attributed to their polyphenolic contents. The mechanism involved to the highest extent in the protective effect of the juices was the inhibition of apoptosis.

Abstract
Peptic ulcer is a chronic disease affecting up to 10% of the world's population. The formation of peptic ulcers depends on the presence of gastric juice pH and the decrease in mucosal defenses. Non-steroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori (H. pylori) infection are the two major factors disrupting the mucosal resistance to injury. Conventional treatments of peptic ulcers, such as proton pump inhibitors (PPIs) and histamine-2 (H2) receptor antagonists, have demonstrated adverse effects, relapses, and various drug interactions. On the other hand, medicinal plants and their chemical compounds are useful in the prevention and treatment of numerous diseases. Hence, this review presents common medicinal plants that may be used for the treatment or prevention of peptic ulcers.

Abstract
The rapidly declining prevalence of Helicobacter pylori infection and widespread use of potent anti-secretory drugs means peptic ulcer disease has become substantially less prevalent than it was two decades ago. Management has, however, become more challenging than ever because of the threat of increasing antimicrobial resistance worldwide and widespread use of complex anti-thrombotic therapy in the ageing population. Peptic ulcers not associated with H pylori infection or the use of non-steroidal anti-inflammatory drugs are now also imposing substantial diagnostic and therapeutic challenges. This Seminar aims to provide a balanced overview of the latest advances in the pathogenetic mechanisms of peptic ulcers, guidelines on therapies targeting H pylori infection, approaches to treatment of peptic ulcer complications associated with anti-inflammatory analgesics and anti-thrombotic agents, and the unmet needs in terms of our knowledge and management of this increasingly challenging condition.

Abstract
BACKGROUND Helicobacter pylori vacA genotypes play an important role in the pathogenesis of severe gastrointestinal disease. MATERIALS AND METHODS We identified a novel polymorphic site in the 3'-end region of H. pylori vacA gene, denoted by c1/-c2 (c1: with deletion of 15 bp), and examined associations of this and the previous four sites as well as cagA status with gastroduodenal diseases, in a total of 217 Iranian H. pylori isolates. Histopathologic evaluations were performed and patients with gastric cancer (GC) were further classified based on the anatomic site of tumor, including cardia and noncardia GC, and the histopathologic type of tumor, including intestinal- and diffuse-type GC. RESULTS The vacA m1, i1, d1, c1, and cagA genotypes were significantly associated with an increased risk of GC, the odds ratio (95% confidence interval) was 4.29 (2.03-9.08), 6.11 (2.63-14.19), 3.18 (1.49-6.76), 15.13 (5.86-39.01), and 2.59 (1.09-6.12), respectively. The vacA c1 genotype had an increased age- and sex-adjusted risk for GC by the multiple logistic regression analysis; the OR was 38.32 (95% CI, 6.60-222.29). This association was independent of and larger than the associations of the m-, i-, and d-type of vacA or cagA status with GC. No significant correlation was found between s1, whether independently or in combination, and the risk of GC or peptic ulcer disease (PUD). The vacA i1 and cagA genotypes were linked to an increased risk of PUD; the OR (95% CI) was 2.80 (1.45-5.40) and 2.62 (1.23-5.61), respectively. The presence of both the vacA i1 and cagA genotypes further increased the risk of PUD; the OR was 5.20 (95% CI, 1.92-14.03). CONCLUSION The H. pylori vacA c1 genotype might therefore be one of the strongest risk predictors of GC in male patients aged ≥55 in Iran.
