Abstract
BACKGROUND Previous observational studies have demonstrated a connection between the risk of Type 2 diabetes mellitus (T2DM) and gastrointestinal problems brought on by Helicobacter pylori (H. pylori) infection. However, little is understood about how these factors impact on T2DM. METHOD This study used data from the GWAS database on H. pylori antibodies, gastroduodenal ulcers, chronic gastritis, gastric cancer, T2DM and information on potential mediators: obesity, glycosylated hemoglobin (HbA1c) and blood glucose levels. Using univariate Mendelian randomization (MR) and multivariate MR (MVMR) analyses to evaluate the relationship between H. pylori and associated gastrointestinal diseases with the risk of developing of T2DM and explore the presence of mediators to ascertain the probable mechanisms. RESULTS Genetic evidence suggests that H. pylori IgG antibody (P = 0.006, b = 0.0945, OR = 1.0995, 95% CI = 1.023-1.176), H. pylori GroEL antibody (P = 0.028, OR = 1.033, 95% CI = 1.004-1.064), gastroduodenal ulcers (P = 0.019, OR = 1.036, 95% CI = 1.006-1.068) and chronic gastritis (P = 0.005, OR = 1.042, 95% CI = 1.012-1.074) are all linked to an increased risk of T2DM, additionally, H. pylori IgG antibody is associated with obesity (P = 0.034, OR = 1.03, 95% CI = 1.002-1.055). The results of MVMR showed that the pathogenic relationship between H. pylori GroEL antibody and gastroduodenal ulcer in T2DM is mediated by blood glucose level and obesity, respectively. CONCLUSION Our study found that H. pylori IgG antibody, H. pylori GroEL antibody, gastroduodenal ulcer and chronic gastritis are all related to t T2DM, and blood glucose level and obesity mediate the development of H. pylori GroEL antibody and gastroduodenal ulcer on T2DM, respectively. These findings may inform new prevention and intervention strategies for T2DM.

Abstract
PURPOSE This study aims to comprehensively review the multifaceted factors underlying the successful colonization and infection process of Helicobacter pylori (H. pylori), a prominent Gram-negative pathogen in humans. The focus is on elucidating the functions, mechanisms, genetic regulation, and potential cross-interactions of these elements. METHODS Employing a literature review approach, this study examines the intricate interactions between H. pylori and its host. It delves into virulence factors like VacA, CagA, DupA, Urease, along with phase variable genes, such as babA, babC, hopZ, etc., giving insights about the bacterial perspective of the infection The association of these factors with the infection has also been added in the form of statistical data via Funnel and Forest plots, citing the potential of the virulence and also adding an aspect of geographical biasness to the virulence factors. The biochemical characteristics and clinical relevance of these factors and their effects on host cells are individually examined, both comprehensively and statistically. RESULTS H. pylori is a Gram-negative, spiral bacterium that successfully colonises the stomach of more than half of the world's population, causing peptic ulcers, gastric cancer, MALT lymphoma, and other gastro-duodenal disorders. The clinical outcomes of H. pylori infection are influenced by a complex interplay between virulence factors and phase variable genes produced by the infecting strain and the host genetic background. A meta-analysis of the prevalence of all the major virulence factors has also been appended. CONCLUSION This study illuminates the diverse elements contributing to H. pylori's colonization and infection. The interplay between virulence factors, phase variable genes, and host genetics determines the outcome of the infection. Despite biochemical insights into many factors, their comprehensive regulation remains an understudied area. By offering a panoramic view of these factors and their functions, this study enhances understanding of the bacterium's perspective, i.e. H. pylori's journey from infiltration to successful establishment within the host's stomach.

Abstract
Peptic ulcer disease (PUD) continues to be a cause of significant morbidity and mortality worldwide. Almost two-thirds of PUD cases are asymptomatic. In symptomatic patients, epigastric pain is the most common presenting symptom of PUD, which is manifested by nausea, abdominal fullness, bloating, and dyspepsia. Most PUD cases are associated with the use of COX inhibitors or Helicobacter pylori infection, or both. The traditional management of PUD includes the use of proton pump inhibitors to reduce the gastric acid secretion and antibacterial drugs to combat H. pylori. Timely diagnosis and treatment of PUD are vital to reduce the risk of associated morbidity and mortality, as is prevention of PUD among patients at high risk, including COX inhibitors users and those infected with H. pylori. PDE5 inhibitors have been used for the management of erectile dysfunction and pulmonary hypertension for decades. In recent years, studies have mentioned tremendous pleiotropic effects of PDE5 inhibitors on gastrointestinal, urogenital, musculoskeletal, reproductive, cutaneous, and neurologic disorders. Recent data shows that PDE5 inhibition augments gastric mucosa protection, and here, we review the most recent findings regarding the use of PDE5 inhibitors for the prevention and management of PUD.

Abstract
Peptic ulcer (PU) has been recognized as an utmost gastrointestinal problem that affects the lining of the stomach and duodenum, specifically triggering soreness. It is a life-threatening condition, while roots of the infection are not identified yet. There are various risk factors for the cause of peptic ulcer disease, but the most significant is "Helicobacter pylori" (H. pylori). The detection of this disease involves different invasive procedures which are painful and not feasible for everyone. The aim of this device is to identify the peptic ulcer non-invasively by unmasking the presence of H. Pylori bacterium by monitoring crucial parameters of the disease which include respiration rate, heart rate, ECG, pH of Saliva, and temperature. Multiple investigations related to PU authenticate the alteration in these physicochemical aspects of the body. The increase in the level of stomach acid in PU is responsible for belching and bloating. Heart rate, temperature, and respiratory rate are also elevated during peptic ulcers while the pH of Saliva is decreased toward the acidic side. The disturbance in the QRS complex of the ECG wave is also observed. These biosignals are examined as analog input from the body, sent into MCP3008, and converted into digital input signals. Then these digital inputs are directed toward Raspberry pi 3 which processes, received inputs, and shows output on the LCD. The values of parameters obtained are then compared with standard values and a conclusion is made that whether a patient has a peptic ulcer or not.

Abstract
In this study, we aimed to investigate the prevalence of bab genes (babA, babB, babC) at their three loci (loci A, B, and C) in Helicobacter pylori strains from varied clinical manifestations of Korean gastroduodenal patients. The overall prevalence of H. pylori Korean strains positive for babA and babB was 91.1% and 92.2%, respectively, but all strains were negative for bab C. H. pylori strains with two loci occupied (loci A and B) were the most prevalent in Korean patients (85.6%), compared to one locus occupied (14.4%) (locus A or B). Twelve bab genotypes were detected, additionally, the distribution of three bab genotypes was significantly associated with different clinical outcomes among Korean patients. The genotypes babA/babB/- and babA/babA+babB/- were significantly associated with peptic ulcer disease (PUD) (63.3%) and gastritis (GT) (33.3%) patients, respectively. In addition, we found that the babA+babB/babA+babB/- genotype was significantly associated with gastric cancer (GC) (36.7%) as compared to GT (6.7%) or PUD (6.7%) (p<0.05) patients. This study provided evidence that the bab genotypes in H. pylori Korean strains were highly variable. Interestingly, three patterns of bab genotypes were significantly different among patients with different clinical outcomes in the population at high-risk for GC.

Abstract
INTRODUCTION Functional dyspepsia (FD), although commoner than organic dyspepsia (OD) in-hospital studies, community data, particularly from rural areas, are lacking. We performed a rural community study in Bangladesh with the primary aims to evaluate (i) the prevalence of uninvestigated dyspepsia (UD), FD, and OD and (ii) the risk factors for UD. METHODS This house-to-house survey was performed using a translated-validated enhanced Asian Rome III questionnaire and endoscopy with Helicobacter pylori tests, including genotyping. RESULTS Of 3,351/3,559 responders ([94.15%], age 40.41 ± 16.05 years, female 1924 [57.4%]), 547 (16.3%) had UD (female 346 [18%] vs male 201 [14%]; P = 0.002); 201 (6%), 88 (2.6%), and 258 (7.7%) had postprandial distress (PDS), epigastric pain syndromes (EPS) and PDS-EPS overlap, respectively. On multivariate analysis, age >50 years (adjusted odds ratio [AOR] 1.34 [1.07-1.68]), female sex (AOR 1.42 [1.17-1.74]), being married (AOR 1.57 [1.21-2.07]), lower family income (AOR 1.79 [1.43-2.26]), nonsteroidal anti-inflammatory drug use (AOR 7.05 [2.11-23.55]), previous acute gastroenteritis (AOR 5.42 [1.83-16]), and psychological distress (AOR 5.02 [2.87-8.76]) were risk factors for UD. Of 346/547 (63.25%) undergoing endoscopy, 232 (67.05%) and 114 (32.95%) had FD and OD (peptic ulcers [PU] 99 [28.61%] and erosive esophagitis 13 [3.76%]). About 53% of FD subjects had EPS-PDS overlap, 32% had PDS, and only 15% had EPS. H. pylori was detected in 266/342 (78%) dyspeptics (FD 173/230 [75.2%], vs OD 92/114 [82.1%], P = 0.169). DISCUSSION Sixteen percent, 11% and 5% of rural Bangladeshi Asian adults had UD, FD, and PU, respectively. One-third of UD subjects had OD, mostly PU.JOURNAL/cltg/04.03/01720094-202104000-00016/inline-graphic1/v/2021-04-15T161418Z/r/image-tiff.

Abstract
Helicobacter pylori causes persistent infection in the gastric epithelium of more than half of the world’s population, leading to the development of severe complications such as peptic ulcer diseases, gastric cancer, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Several virulence factors, including cytotoxin-associated gene A (CagA), which is translocated into the gastric epithelium via the type 4 secretory system (T4SS), have been indicated to play a vital role in disease development. Although infection with strains harboring the East Asian type of CagA possessing the EPIYA-A, -B, and -D sequences has been found to potentiate cell proliferation and disease pathogenicity, the exact mechanism of CagA involvement in disease severity still remains to be elucidated. Therefore, we discuss the possible role of CagA in gastric pathogenicity.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection causes inflammation and increases the risk of developing peptic ulcer disease (PUD); however, the exact molecular mechanisms of PUD development remain unclear. The aim of this study was to investigate the expression of CCL18, CCL28, and CXCL13 in H. pylori-positive subjects in comparison with H. pylori-negative subjects, and to determine its association with different clinical outcomes and virulence factors. METHODS In total, 55 H. pylori-positive subjects with gastritis, 47 H. pylori-positive subjects with PUD, and 48 H. pylori-negative subjects were enrolled in this study. CCL18, CCL28, and CXCL13 expression were determined using real time polymerase chain reaction (PCR). The virulence factors of H. pylori such as cytotoxin-associated gene A (cagA), outer inflammatory protein A (oipA), blood group antigen-binding adhesin (babA), and vacuolating cytotoxin A (VacA) genes were evaluated using PCR. RESULTS CCL18, CCL28, and CXCL13 expression in H. pylori-positive subjects were significantly higher than H. pylori-negative subjects. CCL18 and CXCL13 expression in H. pylori-positive subjects with oipA+ and babA2+were significantly higher than H. pylori-positive subjects with oipA¯ and babA2¯. CCL18 and CXCL13 expression were found to be significantly elevated in H. pylori-positive subjects with gastritis compared with H. pylori-positive subjects with PUD. CCL28 expression was significantly higher in H. pylori-positive subjects with PUD compared with H. pylori-positive subjects with gastritis. CONCLUSIONS The increased of CCL18 and CXCL13 may be involved in the pathogenesis of H. pylori-associated gastritis, while the increased of CCL28 may be involved in the pathogenesis of H. pylori-associated PUD.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is a serious human health threat. The empiric H. pylori treatment paradigm guided by traditional testing technologies has led to antibiotic resistance. Here, we improved the qPCR method to provide technical support for precision H. pylori diagnosis and treatment. METHODS Two pairs of primers and probes targeting the glmM gene were designed to detect H. pylori, and a multiplex qPCR method was established for virulence factor detection. Then, a rapid urease test (RUT), culturing and qPCR were performed on 141 specimens collected from Xinqiao Hospital of China in 2017 to evaluate the qPCR detection capability. Finally, the H. pylori infectious amount and virulence genes were detected by qPCR. RESULTS 1. The improved qPCR method which used two pairs of primers had a higher detection rate (100%) and better accuracy (p = 0.000), compared with the qPCR using a pair of primers. It also had better consistency with the bacterial culture than with RUT (Kappa =0.440, p < 0.001). 2. The H. pylori infectious amount was significantly positively associated with gastritis in corpus (p = 0.003) and gastric erosion (p = 0.043). The H. pylori infectious amount in gastric precancerous patients was significantly lower than that in H. pylori-positive patients (p < 0.05), and the infectious H. pylori-vacA s1+ amount was significantly greater than that of H. pylori-vacA s1- (p < 0.05). 3. The vacA s1 frequency was significantly higher than that of vacA m1/cagA+/babA2+ in chronic superficial gastritis (p = 0.000), peptic ulcer (p = 0.037) and gastric erosion (p = 0.009). The H. pylori-vacA+/cagA+/babA2+ frequency showed a significant positive correlation (p < 0.05). CONCLUSIONS The H. pylori infectious amount and presence of H. pylori virulence factors showed complex correlations with gastric disease occurrence and development. The improved qPCR with good detection performance can be used for quantitative H. pylori detection and testing for the virulence genes vacA s1, vacA m1, cagA and babA2 simultaneously. These findings will provide valuable information for disease diagnosis and treatment.

Abstract
Introduction. Gastric cancer is a health disparity in the Alaska Native people. The incidence of Helicobacter pylori infection, a risk factor for non-cardia gastric adenocarcinoma, is also high. Gastric cancer is partially associated with the virulence of the infecting strain.Aim. To genotype the vacA s, m and i and cag pathogenicity island (cagPAI) genes in H. pylori from Alaskans and investigate associations with gastropathy.Methodology. We enrolled patients with gastritis, peptic ulcer disease (PUD) and intestinal metaplasia (IM) in 1998-2005 and patients with gastric cancer in 2011-2013. Gastric biopsies were collected and cultured and PCR was performed to detect the presence of the right and left ends of the cagPAI, the cagA, cagE, cagT and virD4 genes and to genotype the vacA s, m and i regions.Results. We recruited 263 people; 22 (8 %) had no/mild gastritis, 121 (46 %) had moderate gastritis, 40 (15%) had severe gastritis, 38 (14 %) had PUD, 30 (11 %) had IM and 12 (5 %) had gastric cancer. H. pylori isolates from 150 (57%) people had an intact cagPAI; those were associated with a more severe gastropathy (P≤0.02 for all comparisons). H. pylori isolates from 77 % of people had either the vacA s1/i1/m1 (40 %; 94/234) or s2/i2/m2 (37 %; 86/234) genotype. vacA s1/i1/m1 was associated with a more severe gastropathy (P≤0.03 for all comparisons).Conclusions. In this population with high rates of gastric cancer, we found that just over half of the H. pylori contained an intact cagPAI and 40 % had the vacA s1/i1/m1 genotype. Infection with these strains was associated with a more severe gastropathy.

Abstract
Helicobacter pylori colonizes the gastric epithelial cells of at least half of the world's population, and it is the strongest risk factor for developing gastric complications like chronic gastritis, ulcer diseases, and gastric cancer. To successfully colonize and establish a persistent infection, the bacteria must overcome harsh gastric conditions. H. pylori has a well-developed mechanism by which it can survive in a very acidic niche. Despite bacterial factors, gastric environmental factors and host genetic constituents together play a co-operative role for gastric pathogenicity. The virulence factors include bacterial colonization factors BabA, SabA, OipA, and HopQ, and the virulence factors necessary for gastric pathogenicity include the effector proteins like CagA, VacA, HtrA, and the outer membrane vesicles. Bacterial factors are considered more important. Here, we summarize the recent information to better understand several bacterial virulence factors and their role in the pathogenic mechanism.

Abstract
The immunopathologic responses play a major role in the development of H. pylori (HP)-related gastrointestinal diseases. IL-37 is an anti-inflammatory cytokine with potent suppressive effects on innate and adaptive immune responses. Here, we investigated the IL-37 levels and two single nucleotide polymorphisms (SNPs) including rs3811047 and rs2723176 in IL-37 gene in HP-infected peptic ulcer (PU) patients to identify any relationship. Three groups, including 100 HP-infected PU patients, 100 HP-infected asymptomatic (AS) subjects and 100 non-infected healthy control (NHC) subjects were enrolled to study. Serum IL-37 levels and the genotyping at rs3811047 and rs2723176 were determined using ELISA and SSP-PCR methods, respectively. Significantly higher IL-37 levels were observed in PU patients compared with AS and NHC groups (P < 0.0001). In both PU and AS groups, the CagA+ HP-infected participants displayed higher IL-37 levels compared with those infected with CagA- strains (P < 0.0001). There were significant differences between PU, AS and NHC groups regarding the distribution of genotypes and alleles at rs3811047 and rs2723176 SNPs. The genotype GG and allele G at IL-37 rs3811047 SNP, and the genotype CC and allele C at IL-37 rs2723176 SNP more frequently expressed in PU patients than total healthy subjects (AS + NHC groups) and were associated with an increased risk of PU development (genotype GG: RR = 3.08, P < 0.009; allele G: RR = 2.94, P < 0.01; genotype CC: RR = 5, P < 0.01; and allele C: RR = 5.0, P < 0.02, respectively). The PU patients with allele A at IL-37 rs2723176 SNP expressed higher amounts of IL-37 compared with patients carried allele C at the same position (P < 0.05). In AS carriers and NHC individuals, the IL-37 levels in subjects carried genotype AA or allele A at IL-37 rs2723176 SNP were higher than those carried genotype CC or allele C at the same location (P < 0.01 and P < 0.02 for AS group; P < 0.0001 and P < 0.001 for NHC subjects, respectively). The increased IL-37 levels may be considered as a valuable marker of PU development in HP-infected individuals. The SNPs rs3811047 and rs2723176 were associated with PU development. The CagA status of HP and IL-37 rs2723176 SNP may affect the IL-37 levels.

Abstract
OBJECTIVE To evaluate the effect and safety of Chinese herbal medicines on Helicobacter pylori (HP)-associated gastroduodenal ulcers. METHODS All randomized controlled trials (RCTs) listed in the PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure Database, WanFang, China Science and Technology Journal Database and SinoMed databases that were published in English or Chinese were searched, and the retrieval time range was from database inception to December 31, 2018. A comprehensive Meta-analysis of all publications was performed with RevMan 5.3 software, and the quality of the evidence reported in the results of Meta-analysis was analyzed with GRADE profiler software (version 3.6.1). Dichotomous data were analyzed by calculating odds ratios and 95% confidence intervals (CIs). Outcome measures included the HP clearance rate and percentage of adverse effects. RESULTS Eight trials with 919 participants were included in this Meta-analysis. Compared with the effects of single drug therapy on HP-associated gastroduodenal ulcers, according to the statistical analysis, odds ratios for the HP clearance rate and percentage of adverse effects of Chinese herbal medicines administered as complementary medicines combined with drugs were 3.10 [95% CI (2.21, 4.36), P < 0.01] and 0.28 [95% CI (0.15, 0.52), P < 0.01], respectively, and the differences were statistically significant. According to the GRADE analysis, the quality of evidence for the HP clearance rate and percentage of adverse effects were both very low. CONCLUSION Compared with using the drug therapy only, the combination of Chinese herbal medicines with the drug therapy more effectively eliminates HP and alleviates adverse reactions. However, the available studies were of low quality, and therefore more well-designed studies are required to further confirm the findings.

Abstract
OBJECTIVE To examine the effect of subjective and objective sleep quality on subsequent recurrence of peptic ulcer disease (PUD) among older patients after Helicobacter pylori eradication. SETTING Eight grade A hospitals in China. PARTICIPANTS Of 1689 older Chinese with H. pylori-infected PUD recruited between January 2011 and October 2014, H. pylori were eradicated and PUD was cleared in 1538 patients by the end of 2014; 1420 of these patients were followed up for up to 36 months. MEASUREMENTS Using multiple measures at 6-month intervals, PUD recurrence was determined with esophagogastroduodenoscopy. Subjective sleep quality was measured using the Pittsburgh Sleep Quality Index. Objective sleep quality domains were measured using an accelerometer, including sleep onset latency, sleep efficiency, total sleep time, and number of awakenings. RESULTS This study documented a 36-month cumulative PUD recurrence of 8.3% (annual rate = 2.8%). Multivariate analyses showed that participants who reported poorer sleep quality were more likely to experience PUD recurrence during the 36-month follow-up period (hazard ratio [HR] = 1.895; 95% confidence interval [CI] = 1.008-3.327). Regarding objective sleep quality domains, longer sleep onset latency (HR = 1.558; 95% CI = 1.156-2.278) and more nighttime awakenings (HR = 1.697; 95% CI = 1.168-2.665) increased the risk of PUD recurrence. However, a longer total sleeping time protected against PUD recurrence (HR = 0.768; 95% CI = 0.699-0.885). CONCLUSIONS Poor sleep quality predicts a greater risk of PUD recurrence. Accurate diagnosis and effective treatments should, therefore, be provided for older adults afflicted with poor sleep, particularly for those who previously had PUD. It is equally important to include sleep assessment as an integral part while dealing with these patients.

Abstract
BACKGROUND Peptic ulcer disease (PUD) is a major burden worldwide. Several challenges remain with standard Western treatment of PUD, such as persistent weakness, fatigue, and relapse. A dietary traditional Chinese medicine (TCM) formula, Hou Gu Mi Xi (HGMX), has been developed as a complementary treatment for PUD. AIMS This multicenter, double-blind, randomized controlled trial will assess efficacy and safety of HGMX in patients with PUD. METHODS Three hundred sixty eligible patients will be assigned to receive HGMX, placebo, HGMX + rabeprazole or placebo + rabeprazole for 4 weeks after 2 weeks of standard Western treatment. This first step, with a 2 × 2 factorial design, will focus on assessing the main and interaction effects of HGMX and rabeprazole on ulcer healing. Then, rabeprazole will be stopped, and HGMX will be continued for up to 1 year. The second step, with a placebo-controlled design, will compare the long-term effects of HGMX and placebo. Extended follow-up with no treatment will continue for up to 2 years. Independent and paired t tests, Pearson χ test and the rank-sum test will be used to compare between-group differences. The P value will be adjusted using the O'Brien & Fleming method for multiple comparisons. EXPECTED OUTCOMES The primary outcomes are total efficacy rate of PUD treatment, quality of ulcer healing, and changes in spleen qi deficiency symptoms. The secondary outcomes include ulcer area, PUD recurrence, Helicobacter pylori eradication rate, gastric function, body weight, and body mass index. Adverse events (AEs), severe AEs, treatment-related AEs, and withdrawal owing to AEs will be recorded to assess treatment safety. DISCUSSION The trial results will provide high-quality evidence for HGMX, as a complementary therapy, for the long-term management of PUD and will be valuable for the development of related guidelines and regulations. TRIAL REGISTRATION The protocol of this trial was approved in all research hospitals and was registered in ClinicalTrials.gov at October 25, 2017(No. NCT03320538).

Abstract
BACKGROUND The global prevalence of H. pylori approaches 50%, with prevalence rates between 20 and 40% in developed countries and up to 90% in Africa and other developing nations of the world. Development of H. pylori-associated diseases is determined by a number of virulence factors. This study aimed at determining the prevalence of H. pylori infections and virulence genes (cagA, dupA, and vacA); the relationship between virulence factors and gastroduodenal diseases among patients. METHODS Gastric biopsies were obtained from patients and cultured, DNA was extracted from cultured isolates and biopsies for PCR assay after which samples were investigated using standard laboratory procedures. Data of associated risk factors were obtained with the aid of questionnaires. RESULTS Of the 444 participants, H. pylori was detected in 115 (25.9%) from culture analysis and 217 (48.9%) by direct PCR method. Ninety-eight (85.2%) of the culture-positive patients were also detected by PCR giving an overall prevalence of 52.7% (234/444). The highest number of H. pylori isolates 76.9% (180/234) was obtained from patients suffering from pangastritis. The CagA virulence gene was found in 62% (145/234), dupA in 53.4% (125/234) and vacA in 90.6% (212/234). VacA genotype s1 m1 was the most prevalent [56.4% (132)] followed by s2 m2 [11.5% (27)], s2 m1 [10.3% (24)] and [s1 m2 9.4% (22)]. There was a significant association observed in vacA s1 and peptic ulcer disease, as well as vacA s1/m2 and gastric erosion (P < 0.05). CONCLUSION The study revealed a significant association between virulence genes and the development of certain forms of gastric infections while the variations in H. pylori detection and the associated risk factors investigated in the study were not significantly related.

Abstract
In this narrative review, we have comprehensively reviewed the plant sources used as antiulcer agents. From traditional uses as herbal remedies, we have moved on to preclinical evidence, critically discussing the in vitro and in vivo studies focusing on plant extracts and even isolated phytochemicals with antiulcerogenic potential. A particular emphasis was also paid to Helicobacter pylori activity, with emphasis on involved mechanisms of action. Lastly, the issue of safety profile of these plant products has also been addressed.

Abstract
Previous studies have suggested that peptic ulcer disease (PUD) including stomach and duodenal ulcers might be associated with periodontitis (PD); however, no clear conclusions have been reached thus far. In this retrospective case-control study, we aimed to investigate the association between PUD and PD by using a large population-based dataset in Taiwan. A population-based retrospective case control study was conducted using the Longitudinal Health Insurance Database 2010 (LHID2010) derived from the National Health Insurance Research database (NHIRD) in Taiwan from 2000 to 2013. The case and control group were matched with gender, age, urbanization level, socioeconomic status, and Charlson comorbidity index (CCI) by using the propensity score method at a 1:1 ratio. A total of 177,240 cases and 177,240 control patients were included in this study, with an average age of 46.96 ± 11.76 years. The risk of PUD for patients diagnosed with PD was 1.15-fold when compared with those without PD (OR, 1.15; 95% CI, 1.12–1.18). This population-based case control study demonstrated a significantly positive association between PUD and PD in Taiwan.

Abstract
Peptic ulcer disease (PUD) is a common condition that both primary care providers and gastroenterologists encounter. Symptoms of peptic ulcer disease are variable and may include abdominal pain, nausea, vomiting, weight loss and bleeding or perforation with complicated disease. Identifying the risk factors and mechanisms that lead to the development of PUD helps to understand the approach behind diagnostic and treatment strategies.

Abstract
Objective Due to the Great East Japan Earthquake, which occurred in March 2011, many residents of Fukushima Prefecture were affected by a radiation accident in addition to suffering loss or damage from the earthquake and the subsequent tsunami. The aim of this study was to evaluate the actual condition of patients with peptic ulcers related to the disaster. Methods Patients with peptic ulcers at six hospitals in three different regions of Fukushima Prefecture during the two months following the disaster and the corresponding period of the year before and the year after the disaster were enrolled in this study. Changes by period and region in the number of esophagogastroduodenoscopy (EGD) examinations and the number of peptic ulcer patients were evaluated as the primary endpoints. Changes in the frequencies of hemorrhagic ulcers were evaluated by period and by region as secondary endpoints. Results The numbers of EGDs and peptic ulcer cases compared to the previous year decreased in 2011 and then increased in 2012. However, the ratio of hemorrhagic ulcers to peptic ulcers was higher in 2011 (51.9%) than in 2010 (38.1%) and 2012 (31.1%), and the 2011 hemorrhagic ulcer ratio was the highest at 63.6% in the coastal area. Regarding bleeding cases during 2011, the rate at 1 month after the disaster (64.1%) was higher than the rate at 2 months after the disaster (40.5%) (p=0.033). Conclusion The number of patients with peptic ulcers did not increase immediately following the disaster in Fukushima Prefecture. However, the rate of bleeding patients increased soon after the disaster, especially in the coastal area.

Abstract
The modern therapy for peptic ulcer disease and other acid peptic diseases is based on administration of proton pump inhibitors (PPI) which have fully replaced anacids, parasympatholytics and histamine H2 receptor antagonists. The most effective way is to administer proton pump inhibitors in the morning on an empty stomach in a single daily dose. It is a very safe therapy, despite the fact that a potential adverse effect of long-term PPI treatment on the efficacy of other medications (clopidogrel), on bone metabolism and development of respiratory infections have been discussed recently. PPI also play an essential role in the eradication treatment of Helicobacter pylori infection, the prevention and treatment of gastropathy induced by nonsteroidal anti-inflammatory drugs and in relation to some rare hypersecretory conditions. The role of proton pump inhibitors in the therapy for functional dyspepsia is contradictory. Massive bleeding from the peptic ulcer is a relatively frequent complication of NSAID gastropathy. Endoscopic hemostasis and parenteral administration of PPI for at least 72 hours are used in therapy. Key words: acid peptic diseases - gastric secretion - peptic ulcer - proton pump inhibitors.

Abstract
Helicobacter pylori, which is involved in the pathogenesis of gastroduodenal disease, produces CagA and VacA as major virulence factors. CagA is classified into East Asian and Western types based on the number and sequences of its Glu-Pro-Ile-Tyr-Ala motifs. The vacA gene has three polymorphic regions: the signal (s), intermediate (i), and middle (m) regions. The lowest gastric cancer mortality rate is seen in Okinawa. On the Japanese mainland (Honshu), most H. pylori produce s1/m1-VacA, which exhibits strong toxicity, and East Asian-type CagA. However, the H. pylori detected in Okinawa produces s1/m2-VacA, which exhibits weak toxicity, or s2/m2-VacA, which is non-toxic, and Western-type CagA. Studies about the i-region of vacA have been performed around the world, but there have been few such studies in Japan. Therefore, the aim of this study was to assess the relationships between the clinical outcomes of H. pylori infections in Okinawa, vacA (especially the i-region genotype), and cagA. H. pylori strains that were collected from patients with gastric cancer or gastric ulcers in Okinawa only produced the i1-type VacA virulence factor. The vacuolating cytotoxin activity of i1-type VacA was stronger than that of i2-type VacA, suggesting that the i-region genotype of vacA is closely associated with vacuolating cytotoxin activity. These results indicate that the i-region genotype of vacA is a useful marker of both H. pylori virulence and the clinical outcomes of H. pylori infections in Okinawa, Japan.

Abstract
PURPOSE OF REVIEW The discovery of Helicobacter pylori and other organisms colonizing the stomach and the intestines has shed some light on the importance of microbiome in maintaining overall health and developing pathological conditions when alterations in biodiversity are present. The gastric acidity plays a crucial role in filtering out bacteria and preventing development of enteric infections. In this article, we discuss the physiology of gastric acid secretion and bacterial contribution to the composition of gastric and intestinal barriers and review the current literature on the role of proton pump inhibitors (PPIs) in the microbial biodiversity of the gastrointestinal tract. RECENT FINDINGS Culture-independent techniques, such as 16S rRNA sequencing, have revolutionized our understanding of the microbial biodiversity in the gastrointestinal tract. Luminal and mucosa-associated microbial populations are not identical. Streptococcus is overrepresented in the biopsies of patients with antral gastritis and may also be responsible for the development of peptic ulcer disease. The use of PPIs favors relative streptococcal abundance irrespective of H. pylori status and may explain the persistence of dyspeptic symptoms in patients on PPI therapy. Increased risk of enteric infections has also been seen in patients taking PPIs. The overuse of PPIs leads to significant shift of the gastrointestinal microbiome towards a less healthy state. With the advent of PPIs, many studies have demonstrated the significant changes in the microbial composition of both gastric and intestinal microbiota. Although they are considered relatively safe over-the-counter medications, PPIs in many cases are over- and even inappropriately used. Future studies assessing the safety of PPIs and their role in the development of microbiome changes should be encouraged.

Abstract
Nearly half of the global population are carriers of Helicobacter pylori (H. pylori), a Gram-negative bacterium that persists in the healthy human stomach. H. pylori can be a pathogen and causes development of peptic ulcer disease in a certain state of the macroorganism. It is well established that H. pylori infection is the main cause of chronic gastritis and peptic ulcer disease (PUD). Decontamination of the gastric mucosa with various antibiotics leads to H. pylori elimination and longer remission in this disease. However, the reasons for repeated detection of H. pylori in recurrent PUD after its successful eradication remain unclear. The reason for the redetection of H. pylori in recurrent PUD can be either reinfection or ineffective anti-Helicobacter therapy. The administration of antibacterial drugs can lead not only to the emergence of resistant strains of microorganisms, but also contribute to the conversion of H. pylori into the resting (dormant) state. The dormant forms of H. pylori have been shown to play a potential role in the development of relapses of PUD. The paper discusses morphological H. pylori forms, such as S-shaped, C-shaped, U-shaped, and coccoid ones. The authors proposes the classification of H. pylori according to its morphological forms and viability.

Abstract
Different virulence factors are involved in Helicobacter pylori pathogenesis. H. pylori outer membrane proteins are a family of virulence factors that have diverse members. HopQ (H. pylori outer membrane protein) is the largest of them that contains types I and II alleles. The role of hopQ is not exactly known, but it has been considered in H. pylori adhesion and colonization. The aim of this study was to determine the frequency of hopQ genotypes among H. pylori isolates obtained from patients with gastroduodenal disorders and their association with the clinical outcome. The DNA of 100 H. pylori clinical isolates was investigated by polymerase chain reaction (PCR) method using specific primers for determining the hopQI and hopQII genotypes. hopQI was present in 35%, while hopQII was positive in 55% of the isolates. Amongst the gastritis subjects, the rate of hopQII compared to hopQI was higher, and a statistically significant difference was found between hopQII genotype and the clinical outcome. With respect to the significant difference between the hopQ genotype and clinical outcome in our clinical isolates, it seems that this genotype is a useful marker for evaluating its association with H. pylori-related diseases.

Abstract
Objectives The aim of this study is to clarify the associations between IL-1B31C/T, IL-1B-511C/T, IL-8-251T/A gene polymorphisms and the risk of Helicobacter pylori (H. pylori) infection together with H. pylori-related gastric cancer (GC), peptic ulcer disease (PUD). Methods All eligible literature published up to July 2016 were identified by searching Pubmed, Embase, Web of Science and CNKI. Pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated using a fixed or random effects model. Results 29 case-control studies were eligible, and each of them may focus on more than one gene polymorphism. Ultimately, there were 21 studies (3159 cases and 2816 controls) for IL-1B-31C/T, 16 studies (2486 cases and 1989 controls) for IL-1B-511C/T polymorphisms, 9 studies (1963 cases and 1205 controls) for IL-8-251T/A polymorphisms. Overall, an increased risk of H. pylori infection was found for IL-1B-31C/T polymorphisms in total population [OR = 1.134, 95%CI = 1.008–1.275 for recessive model; OR = 1.145, 95%CI = 1.007–1.301 for TT vs CC model]. While, for IL-1B-511C/T and IL8-251T/A polymorphisms, no evidence indicated that they were associated with the risk of H. pylori infection in all genetic models. Furthermore, we found an increased risk of H. pylori-related GC with IL-1B-511C/T polymorphisms [OR = 1.784, 95%CI = 1.289–2.469 for recessive model; OR = 1.772, 95%CI = 1.210–2.594 for TT vs CC model] and IL8-251A/T polymorphisms [OR = 1.810, 95%CI = 1.229–2.667 for recessive model; OR = 1.717, 95%CI = 1.143–2.580 for TT vs AA model], an increased risk of H. pylori-related PUD with IL8-251T/A polymorphisms [OR = 1.364, 95%CI = 1.010–1.843 for recessive model; OR = 1.427, 95%CI = 1.039–1.959 for AA vs TT model]. Conclusions IL-1B-31C/T gene polymorphisms might increase H. pylori infection risk. IL-1B-511-C/T and IL-8-251T/A gene polymorphisms might act as a risk factor to H. pylori-related diseases including GC or PUD

Abstract
OBJECTIVE Helicobacter pylori has been implicated as a risk factor for development of marginal ulceration following gastric bypass, although studies have been small and yielded conflicting results. This study sought to determine the relationship between H. pylori infection and development of marginal ulceration following bariatric surgery in a nationwide analysis. METHODS This was a retrospective cohort study using the 2012 Nationwide Inpatient Sample (NIS) database. Discharges with ICD-9-CM code indicating marginal ulceration and a secondary ICD-9-CM code for bariatric surgery were included. Primary outcome was incidence of marginal ulceration. A stepwise forward selection model was used to build the multivariate logistic regression model based on known risk factors. A P value of 0.05 was considered significant. RESULTS There were 253,765 patients who met inclusion criteria. Prevalence of marginal ulceration was 3.90%. Of those patients found to have marginal ulceration, 31.20% of patients were H. pylori-positive. Final multivariate regression analysis revealed that H. pylori was the strongest independent predictor of marginal ulceration. CONCLUSIONS H. pylori is an independent predictor of marginal ulceration using a large national database. Preoperative testing for and eradication of H. pylori prior to bariatric surgery may be an important preventive measure to reduce the incidence of ulcer development.

Abstract
Hans Selye in a note to Nature in 1936 initiated the field of stress research by showing that rats exposed to nocuous stimuli responded by way of a 'general adaptation syndrome' (GAS). One of the main features of the GAS was the 'formation of acute erosions in the digestive tract, particularly in the stomach, small intestine and appendix'. This provided experimental evidence for the view based on clinical data that gastro-duodenal (peptic) ulcers could be caused by stress. This hypothesis was challenged by Marshall and Warren's Nobel Prize (2005)-winning discovery of a causal association between Helicobacter pylori and peptic ulcers. However, clinical and experimental studies suggest that stress can cause peptic ulceration in the absence of H. pylori Predictably, the etiological pendulum of gastric and duodenal ulceration has swung from 'all stress' to 'all bacteria' followed by a sober realization that both factors play a role, separately as well as together. This raises the question as to whether stress and H. pylori interact, and if so, how? Stress has also been implicated in inflammatory bowel disease (IBD) and related disorders; however, there is no proof yet that stress is the primary etiological trigger for IBD. Central dopamine mechanisms seem to be involved in the stress induction of peptic ulceration, whereas activation of the sympathetic nervous system and central and peripheral corticotrophin-releasing factor appears to mediate stress-induced IBD.

Abstract
Pantoprazole is a proton pump inhibitor that is commonly used in the treatment of peptic ulcer disease (PUD) and metabolized by cytochrome P450 (CYP) enzymes CYP2C19 and CYP3A4. Pantoprazole is a substrate for multi-drug resistance protein 1 (MDR1). Single nucleotide polymorphisms (SNPs) in CYP2C19, CYP3A4 and MDR1 affect enzyme activity or gene expression of proteins and may alter plasma pantoprazole concentrations and treatment success in PUD. In this study, we aimed to investigate the association between genetic polymorphisms in CYP2C19, CYP3A4 and MDR1 and pharmacokinetics of pantoprazole and therapeutic outcome in patients with either Helicobacter pylori-associated [H.P.(+)]-PUD or [H.P.(+)]-gastritis. The plasma pantoprazole concentrations were determined by using an HPLC method at the third hour after a 40-mg tablet of pantoprazole administration in 194 newly diagnosed patients with either [H.P.(+)]-PUD or [H.P.(+)]-gastritis. Genotyping was performed by using PCR-RFLP and DNA sequencing. Among patients appearing for follow-up examination (n = 105), the eradication rate for H. pylori was 82.8% (n = 87). The median pantoprazole plasma concentrations in poor metabolizers (PM), rapid metabolizers (RM) and ultrarapid metabolizers (URM) were 2.07, 1.69 and 1.28 μg/ml, respectively (p = 0.04). CYP3A4*1G and *22 polymorphisms did not affect plasma pantoprazole concentrations and H. pylori eradication rate. The MDR1 genetic polymorphisms did not affect plasma pantoprazole concentrations. MDR1 3435CC-2677GG-1236CC haplotype carriers had lower H. pylori eradication rate (60%) than the remaining subjects (84.9%) while the difference was not statistically significant (p = 0.07). In conclusion, while CYP2C19 genetic polymorphisms significantly affected plasma pantoprazole concentrations, polymorphisms of CYP2C19, CYP3A4 and MDR1 did not affect H. pylori eradication rates.

Abstract
BACKGROUND Leading causative factors of peptic ulcer disease (PUD) in the general population are infection with Helicobacter pylori (HP) and exposure to non-steroidal anti-inflammatory drugs (NSAID). We hypothesized that this may be different in transplant recipients given increased exposure of immunosuppressive and anti-microbial drugs. METHODS We performed a retrospective single center analysis of all patients presenting with PUD to the endoscopy unit at a tertiary care and transplant center in Germany between 2006 and 2013. PUD was diagnosed by upper endoscopy. HP was identified by biopsy and histology. Organ transplant recipients were compared to non-transplant recipients (control group). RESULTS 66 patients with PUD were identified in the study period. 12% (44/366) had previously received an organ transplant. 7% (3/44) of transplant recipients were found to be positive for HP compared to 25% (81/322) in the control group (p=0.007). Even when excluding patients taking proton-pump-inhibitors (PPI) from the analysis rates were similar with 30% (65/214) of the ulcers being HP positive in the control group compared to 14% (1/7) in transplant recipients (p=0.006). Furthermore, in the transplant recipient group rates of being in intensive care, concurrent PPI and concurrent antibiotic medication were significantly higher than in the control group. CONCLUSION Organ transplant recipients with PUD have lower rates of Helicobacter pylori positivity compared to the general population.

Abstract
BACKGROUND AND AIM Upper gastrointestinal endoscopic findings, such as esophagitis, Barrett's esophagus, peptic ulcer, and malignancy, represent a public health problem. This systematic review aimed to evaluate the prevalence of upper gastrointestinal endoscopic findings in the community. METHODS A systematic search was conducted in PUBMED and EMBASE to May 2015. Studies were eligible if they reported the prevalence of upper gastrointestinal endoscopic findings in unselected samples of the community. RESULTS Twelve articles were eligible, nine reported data from three endoscopic surveys (n = 3063 subjects), and three from national screening programs (n = 84 153). The overall prevalence of upper gastrointestinal endoscopic findings in the community was 30% in the Kalixanda study (Sweden), 24.9% in the Loiano-Monghidoro study (Italy), and 68.9% in the Systematic Investigation of Gastrointestinal Diseases study (China). The pooled prevalence of esophagitis, endoscopically suspected esophageal metaplasia (ESEM), peptic ulcer, and gastric cancer in all studies was 11.2, 5.1, 6.8, and 0.33%, respectively. The most frequent finding was esophagitis in Europe, with a prevalence of 15.5% in Sweden and 11.8% in Italy, and peptic ulcer in China (17.1%), both in asymptomatic and symptomatic individuals. The prevalence of Helicobacter pylori was positively associated with the prevalence of peptic ulcer (r = 0.91) but negatively associated with the prevalence of both esophagitis (r = -0.99) and ESEM (r = -0.95). CONCLUSIONS Upper gastrointestinal endoscopic findings are present in at least a quarter of subjects in the community with different patterns in Western and Eastern countries, both in asymptomatic and symptomatic subjects. H. pylori prevalence negatively impacts on the prevalence of reflux-related esophageal findings.

Abstract
AIM The goal of the study is to assess the impact of the etiological and risk factors in the cases of urgent gastroduodenal ulcer. METHODS This is a prospective study which included 67 patients selected randomly, all with urgent, life-threatening complications of the gastroduodenal ulcer, treated at the University Clinic for Digestive Surgery and the University Clinic for Gastroenterohepatology. For the purpose of the study the titer of IgG antibodies to Helicobacter pylori in serum is examined, as well as the use of NSAID and aspirin. We also tested the use of nicotine and alcohol. Besides these factors, we took into consideration the sex and the age. RESULTS The serological test of Helicobacter pylori was positive in 89.6% of the cases. 31.3% used NSAID and 16.4% used aspirin. Large number, 65.7% of the patients were smokers, while 25.4% used alcohol. With regard to the sex, 83.6% were male and 16.4% were female. The most frequent age group was the one from 41 to 60 years with 40.3% and those between 61 and 80 years of age with 35.8%. CONCLUSION The presence of Helicobacter pylori with the urgent gastroduodenal ulcer was exceptionally high, in 89.6% of the duodenal and gastric ulcers. NSAID and aspirin are factors that also influence the etiology of this disease. Smoking is a significant risk factor. Alcohol is less present, but still an important factor.

Abstract
OBJECTIVE To investigate the prevalence of cagA, vacA, and iceA genotypes in the isolated strains of Helicobacter pylori (H.pylori) from children with gastroduodenal diseases in Jiangxi, China, as well as the association between cagA, vacA, and iceA genotypes and the type of gastroduodenal diseases. METHODS The samples of gastric antral mucosa were collected from 316 children with gastroduodenal diseases in Jiangxi, and a total of 107 strains of H.pylori were isolated. The genomic DNA of these strains was extracted, and PCR was used to determine the ureA, cagA, vacA, and iceA genotypes. RESULTS Of all the 107 isolated strains of H.pylori, the detection rates of ureA and cagA genes were 100% (107/107) and 94.4% (101/107) respectively. The overall detection rate of vacA gene was 100% (107/107), and the detection rates of vacAs1a, vacAs1c, vacAm1, and vacAm2 genes were 74.8% (80/107), 25.2% (27/107), 29.9% (32/107), and 69.2% (74/107) respectively, with both vacAm1 and vacAm2 genes detected in 0.9% (1/107) of all H.pylori strains. In the chimera of vacA gene, the detection rates of vacAs1a/m1, vacAs1a/m2, vacAs1c/m1, and vacAs1c/m2 genes were 26.2% (28/107), 51.4% (55/107), 3.7% (4/107), and 17.8% (19/107) respectively (P<0.001). The detection rates of iceA1 and iceA2 genes were 79.4% (85/107) and 9.3% (10/107), respectively (P<0.001), and both iceA1 and iceA2 genes were detected in 7.5% (8/107) of all strains. The detection rates of the genotypes of H.pylori showed no significant differences between the peptic ulcer, chronic gastritis, and duodenal bulbar inflammation groups (P>0.05). CONCLUSIONS The dominant genotypes of H.pylori are cagA, vacAs1a/m2, and iceA1, and there are mixed infections with H.pylori strains of different genotypes in children with gastroduodenal disease from Jiangxi, China. The genotypes of H.pylori are not associated with the type of gastroduodenal disease.

Abstract
BACKGROUND Currently only a few studies compare sequential and concomitant non-bismuth Helicobacter pylori therapies referring to high antibiotic resistance populations. MATERIALS AND METHODS This multicenter prospective randomized clinical trial included 353 H. pylori positive, treatment naïve, patients. All patients had positive CLO-test and/or histology and culture. They received sequential (esomeprazole 40mg, amoxicillin 1g/bid for 5days, followed by 5days of esomeprazole 40mg, clarithromycin 500mg and metronidazole 500mg bid), or concomitant treatment (all drugs taken concomitantly bid for 10days). Eradication was confirmed by (13)C-urea breath test or histology 4-6weeks after treatment. Adverse events and adherence were evaluated. RESULTS Allocated to concomitant were 175 (72F/103M, mean 52.3years, 38.3% smokers, 25.7% ulcer disease) and 178 (87F/91M, mean 52years, 31% smokers, 19.1% ulcer disease) patients to sequential treatment. There were 303/353 (85.8%) positive cultures, with the following resistances: 34% metronidazole, 27.7% clarithromycin, and 7.9% dual. Eradication rates were, respectively, 89.1% (156/175) vs. 78.7% (140/178) by intention to treat (p=0.01, 95% CI=2.7-18) and 93.4%(156/167) vs. 82.8% (140/169) per protocol (p=0.004, 95% CI=3.6-17.6). Overall, adherence was (98.9%, 95% CI=97-100). Eradication rates according to resistance were the following: dual susceptible strains 67/69 (97.1%), 62/67 (92%) (p=0.4), metronidazole single resistant 38/39 (97.4%), 31/39 (79.5%) (p=0.03, 95% CI=3.5-33), clarithromycin single resistant 25/28 (89.3%), 26/31 (83.9%) (p=0.8), and dual resistant 9/12 (75%), 4/11 (36.4%) (p=0.1) for concomitant and sequential regimens, respectively. Side effects were comparable among regimens, except from diarrhea being more frequent among patients treated with concomitant treatment. CONCLUSIONS Concomitant treatment eradication rate overcomes 90% per protocol and has a significant advantage over sequential therapy. This is probably due to its better efficacy on metronidazole resistant strains. Both regimens were well tolerated and safe.

Abstract
AIM: To evaluate the applicability of nonbismuth concomitant quadruple therapy for Helicobacter pylori (H. pylori) eradication in Chinese regions.
METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the efficacy of nonbismuth concomitant quadruple therapy between sequential therapy or triple therapy for H. pylori eradication in Chinese regions. The defined Chinese regions include China, Hong Kong, Taiwan, and Singapore. The primary outcome was the H. pylori eradication rate; the secondary outcome was the compliance with therapy. The PubMed, Embase, Scopus, and Cochrane databases were searched for studies published in the period up to March 2016 with no language restriction.
RESULTS: We reviewed six randomized controlled trials and 1616 patients. In 3 trials comparing concomitant quadruple therapy with triple therapy, the H. pylori eradication rate was significantly higher for 7-d nonbismuth concomitant quadruple therapy than for 7-d triple therapy (91.2% vs 77.9%, risk ratio = 1.17, 95%CI: 1.09-1.25). In 3 trials comparing quadruple therapy with sequential therapy, the eradication rate was not significant between groups (86.9% vs 86.0%). However, higher compliance was achieved with concomitant therapy than with sequential therapy.
CONCLUSION: The H. pylori eradication rate was higher for nonbismuth concomitant quadruple therapy than for triple therapy. Moreover, higher compliance was achieved with nonbismuth concomitant quadruple therapy than with sequential therapy. Thus, nonbismuth concomitant quadruple therapy should be the first-line treatment in Chinese regions.

Abstract
The Helicobacter pylori vacuolating cytotoxin (VacA) is a secreted pore-forming toxin and a major virulence factor in the pathogenesis of H. pylori infection. While VacA is present in almost all strains, only some forms are toxigenic and pathogenic. While vacA and its genotypes are considered as markers of H. pylori-related diseases or disorders, the pathophysiological mechanisms of VacA and its genotypes remain controversial. This review outlines key findings of publications regarding vacA with emphasis on the relationship between vacA genotypes and the development of human disease.

Abstract
There was held an useful eradication of Helicobacter Pylon in 20 patients with peptic ulcers (Omeprazole, Clarithromycin and Amoxicillin in normal doses). A five - year monitoring period revealed clinical manifestations of relapse in 50% of cases and endoscopic manifestatiQns in 60% of cases (15% - ulcers and 45% - gastral erosions). Relapse of peptic ulcers was accompanied with change of clinical course, it became oligo- or asymptomatic in 83% of patients. Relapse of peptic ulcers was fixed in 45% of patients (15% - in patients with ulcer and 30% - in patients with gastral erosions), at that, erosions were caused by NSAIDs in a half of cases, accompanied with a weak degree of contamination and inflammation of gastral rnucosa.

Abstract
AIM Determine the qualitative and quantitative composition of the mucosal microflora of oesophagogastroduodenal zone to determine the location of Helicobocter pylori and its place in normomicrobiocenosis and dysbacteriosis in cases of peptic ulcer, chronic gastritis and oesophagitis. MATERIALS AND METHODS Clinical and microbiological studies were conducted in 30 healthy individuals-volunteers, 130 patients with peptic ulcer, 36--chronic gastritis and 24--chronic esophagitis. RESULTS OF THE STUDY Helicobacter pylori in 33% of cases included in normomicrobiocenosis of mucosal microflora oesophagogastroduodenal zone, which consists of 12 genera of microorganisms and carries out all protection functions. The recurrence of peptic ulcer disease, exacerbation of chronic active gastritis and oesophagitis are accompanied by a dysbacteriosis of mucosal microflora with overgrowth of typical and atypical microorganisms for normal biotope with reduced occurrenceof Helicobocter pylori. CONCLUSION Helicobacter pylori in the biocenosis of mucosal microflora of oesophagogastroduodenal zone is not an infection, has no independent significance in the development of peptic ulcer, chronic gastritis and esophagitis, does not require eradication.

Abstract
Peptic ulcer disease is a multi-factorial disorder of the gastrointestinal tract with a global prevalence affecting about 4.6 million people annually and having a mortality of one death per 10,000 cases. Helicobacter pylori (H. pylori) plays a profound role in the pathogenesis of chronic gastritis, peptic ulcer, including gastric mucosa-associated lymphoid tissue and carcinoma. Any compromise to the gastric mucosal barrier will greatly affect the integrity of the stomach. H. pylori is an organism which mediates a compromise of the gastric mucosal barrier by stimulating increased gastric acid secretion, causing alteration of certain immune factors, penetration of the mucosal layer and provoking persistent inflammation even without invading the mucus membrane. All the different lines of therapy have not shown maximal efficacy in the eradication/cure of the infection in patients. Consequently, alternative therapies including phytomedicines and probiotics have been introduced both in the quest for better eradication therapies and in addressing the problem of H. pylori relapse. In the light of the increasing antibiotic resistance associated with current therapies, the use of herbal preparations or its concomitant use with current therapy has the potential to contribute additive and synergistic effect in the eradication of the H. pylori infection. This review highlights the anti-H. pylori herbal preparations tested and in current use.

Abstract
OBJECTIVE To observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication. METHODS Totally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed. RESULTS The total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope. CONCLUSION YHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.
