Background and purpose The study analyzed the association of functionally significant polymorphisms of matrix metalloproteinases (MMPs) genes with the development of gastric ulcer (GU) in Caucasians from Central Russia. Methods The 781 participants, including 434 patients with GU (196 Helicobacter pylori (H. pylori)-positive and 238 H. pylori-negative) and 347 controls (all H. pylori-negative) were recruited for the study. Ten SNPs of the MMP1 (rs1799750), MMP2 (rs243865), MMP3 (rs679620), MMP8 (rs1940475), and MMP9 (rs3918242, rs3918249, rs3787268, rs17576, rs17577, and rs2250889) genes were considered for association with GU using multiple logistic regression. The SNPs associated with GU and loci linked (r2≥0.8) to them were analyzed in silico for their functional assignments. Results The SNPs of the MMP9 gene were associated with H. pylori-positive GU: alleles C of rs3918249 (OR = 2.02, pperm = 0.008) and A of rs3787268 (OR = 1.60–1.82, pperm ≤ 0.016), and eight haplotypes of all studied MMP9 gene SNPs (OR = 1.85–2.04, pperm ≤ 0.016) increased risk for H. pylori-positive GU. None of the analyzed SNPs was independently associated with GU and H. pylori-negative GU. Two haplotypes of the MMP9 gene (contributed by rs3918242, rs3918249, rs17576, and rs3787268) increased risk for GU (OR = 1.62–1.65, pperm ≤ 0.006). Six loci of the MMP9 gene, which are associated with H. pylori-positive GU, and 65 SNPs linked to them manifest significant epigenetic effects, have pronounced eQTL (17 genes) and sQTL (6 genes) values. Conclusion SNPs of the MMP9 were associated with H. pylori-positive GU but not with H. pylori-negative GU in Caucasians of Central Russia.

Despite the synergistic effect of Opisthorchis viverrini and Helicobacter pylori co-infection on pathogenesis of severe hepatobiliary abnormalities (HBA) including advanced periductal fibrosis and replace with cholangiocarcinoma (CCA) have been established, the immune response to H. pylori in O. viverrini infected population has never been explored. Hence, this study aimed to investigate the antibody responses to 2 immunogenic H. pylori proteins in O. viverrini-infected patients with HBA and CCA. The risk analysis by multinomial logistic regression revealed that GroEL seropositivity was associated with higher risks of hepatobiliary abnormalities and CCA with adjusted odds ratios (95% confidence intervals) of 2.11 (95% CI=1.20-3.71, P=0.008) and 2.13 (95% CI=1.21-3.75, P=0.009), respectively. These findings indicate that GroEL seropositivity might be a biomarker for early detection of O. viverrini associated HBA and CCA.

AbstractThis study analyzed the association of functionally significant SNPs of matrix metalloproteinase (MMP) genes in the development of peptic ulcer disease (PUD) in Caucasians from Central Russia. Ten SNPs of the MMP-1, MMP-2, MMP-3, MMP-8, and MMP-9 genes were analyzed for association with PUD in a cohort of 798 patients with PUD (including 404 H. pylori-positive and 394 H. pylori-negative) and 347 H. pylori-negative controls using logistic regression and assuming the additive, recessive, and dominant genetic models. The variants of MMP-1, MMP-2, MMP-3, and MMP-8 did not manifest any significant associations with the diseases. Five SNPs of the MMP-9 gene demonstrated such association. Allele G of the rs17576 MMP-9 locus conferred a higher risk for PUD (ORadj = 1.31, pperm = 0.016), haplotype AACG of loci rs17576-rs3787268-rs2250889-rs17577 of the MMP-9 gene decreased risk for PUD (ORadj = 0.17, pperm = 0.003). Also, allele C of rs3918249, allele G of rs17576 and haplotype CG of rs3918249-rs17576 of the MMP-9 gene increased risk for H. pylori-positive PUD (ORadj = 1.82, pperm = 0.002; ORadj = 1.53–1.95 pperm = 0.001–0.013 and ORadj = 1.49 pperm = 0.009 respectively). The above loci and 50 linked to them possess significant regulatory effects and may affect the alternative splicing of four genes and the expression of 17 genes in various organs and tissues related to the PUD pathogenesis.

OBJECTIVE: To determine patient and perioperative characteristics associated with unexpected postoperative clinical deterioration as determined for the need of a postoperative emergency response team (ERT) activation. DESIGN: Retrospective case–control study. SETTING: Tertiary academic hospital. PARTICIPANTS: Patients who underwent general anaesthesia discharged to regular wards between 1 January 2013 and 31 December 2015 and required ERT activation within 48 postoperative hours. Controls were matched based on age, sex and procedure. MAIN OUTCOME MEASURES: Baseline patient and perioperative characteristics were abstracted to develop a multiple logistic regression model to assess for potential associations for increased risk for postoperative ERT. RESULTS: Among 105 345 patients, 797 had ERT calls, with a rate of 7.6 (95% CI, 7.1–8.1) calls per 1000 anaesthetics (0.76%). Multiple logistic regression analysis showed the following risk factors for postoperative ERT: cardiovascular disease (odds ratio [OR], 1.61; 95% CI, 1.18–2.18), neurological disease (OR, 1.57; 95% CI, 1.11–2.22), preoperative gabapentin (OR, 1.60; 95% CI, 1.17–2.20), longer surgical duration (OR, 1.06; 95% CI, 1.02–1.11, per 30 min), emergency procedure (OR, 1.54; 95% CI, 1.09–2.18), and intraoperative use of colloids (OR, 1.50; 95% CI, 1.17–1.92). Compared with control participants, ERT patients had a longer hospital stay, a higher rate of admissions to critical care (55.5%), increased postoperative complications, and a higher 30-day mortality rate (OR, 3.36; 95% CI, 1.73–6.54). CONCLUSION: We identified several patient and procedural characteristics associated with increased likelihood of postoperative ERT activation. ERT intervention is a marker for increased rates of postoperative complications and death.

Aim: Helicobacter pylori (H. pylori) infection and periodontitis have considerable worldwide prevalence once they both present systemic alterations with a possible association between them. Therefore, we have performed this meta-analysis to assess the possible association between H. pylori infection and periodontitis. Material and Methods: A systematic search in the literature was performed for studies published before December 2, 2019 in diverse scientific and educational databases. The data was extracted by two investigators and the statistical analysis was performed by Review Manager statistical program with heterogeneity and Odds Ratio (OR) with 95% of Confidence Intervals (CI) calculations as well as a sensitive analysis to assess the accuracy of the results. The value of P<0.05 was considered as significant. In addition, we performed the analysis of the quality of included studies as well as the evaluation for risk of bias. Results: In overall analysis, H. pylori infection was associated with the risk of periodontitis development (OR = 1.72, CI: 1.47, 2.02, P<0.00001) and the periodontitis was considered as a risk factor for H. pylori infection (OR = 3.21, CI: 2.31, 4.47, P<0.00001). Moreover, the evaluation of dental plaque from patients with periodontitis reveled increased risk of H. pylori infection (OR = 3.46, CI: 2.39, 5.01, P<0.00001). Conclusions: This current systematic review and meta-analysis composed by 12 studies in 7,059 participants showed that H. pylori infection increased significantly the risk of the development of periodontitis and the periodontitis may be a risk for this bacterial infection.

CXC Chemokine Ligand 8 (CXCL8) plays an important role in gastric inflammation and in the progression of gastric cancer induced by Helicobacter pylori (H. pylori) infection. The association of CXCL8, CXC Chemokine Receptor 1 (CXCR1), and CXC Chemokine Receptor 2 (CXCR2) polymorphisms with H. pylori infection and gastric cancer progression needs to be investigated in a population within an enigma area consisting of multiple ethnicities, such as Thailand. To analyze the relative risk of H. pylori infection and gastric cancer among Thai gastroduodenal patients, gene polymorphisms in CXCL8 (promoter region -251) and in CXCR1 and CXCR2 (receptors for CXCL8) were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele specific-PCR (AS-PCR). We also determined the presence of cytotoxin-associated gene A (cagA) in Thai patients with H. pylori infection. Correlation between the CXCL8 (-251) polymorphism and CXCL8 gene expression was evaluated by quantitative reverse transcriptase-PCR (qRT-PCR). We found a significant association between the T/A and A/A genotypes of CXCL8 (-251) with H. pylori infection. However, no significant correlation was found between the CXCR1 (+2607) and CXCR2 (+1208) gene polymorphisms with H. pylori infection among Thai gastroduodenal subjects. Within the H. pylori-infected group of Thai gastroduodenal patients, no significant differences in cagA were observed. In addition, the A/A genotype of CXCL8 (-251) significantly correlated with the risk of gastric cancer and correlated with higher CXCL8 gene expression levels in Thai gastroduodenal patients. These results suggest that CXCL8 (-251) polymorphisms are associated with H. pylori infection, an increased risk of stronger inflammatory responses, and gastric cancer in Thai gastroduodenal patients.

Background. Two major causes of gastric ulcers areHelicobacter pylori(H. pylori) infection and nonsteroidal anti-inflammatory drug (NSAID) use.Aims. This study aimed to determine if there were different expressions of matrix metalloproteinases (MMPs) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) betweenH. pylori-infected and NSAID-related ulcers.Methods. The 126 gastric ulcer patients (H. pyloriinfectedn=46; NSAID relatedn=30; combined with two factorsn=50) provided ulcer and nonulcer tissues for assessment of MMP-3, -7, and -9 and TIMP-1 expression by immunohistochemical staining.Results. Gastric ulcer tissues had significantly higher MMP-3, -7, and -9 and TIMP-1 expressions than nonulcer tissues (P<0.05).H. pylori-infected gastric ulcers had even higher MMP-7, MMP-9, and TIMP-1 expressions in epithelial cells than NSAID-related gastric ulcers (P<0.05). In patients with the two combined factors, gastric ulcers expressed similar proportions of antral ulcers and MMP-7 and MMP-9 intensities to NSAID-related gastric ulcers, but lower MMP-9 and TIMP-1 thanH. pylori-infected gastric ulcers (P<0.05).Conclusions. H. pylori-infected gastric ulcers express higher MMP-7, MMP-9, and TIMP-1 than NSAID-related ulcers. In patients with the two combined factors, ulcer location and MMP-7 and MMP-9 intensities are similar to NSAID use.

Introduction: Helicobacter pylori (H. pylori) is a well-recognized risk factor for upper gastrointestinal bleeding (UGIB). The exposure to tissue plasminogen activator (tPA), anti-platelets, and anticoagulants increases the risk of UGIB in acute ischemic stroke (AIS) patients, the risk stratification of H. pylori infection is not known. In this retrospective cross-sectional study, we aimed to evaluate the relationship between H. pylori and GIB in patients hospitalized with AIS. Methods: In the nationwide data, hospitalization for AIS was identified by primary diagnosis using International Classification of Diseases, clinical modification (ICD-9-CM) codes. Subgroup of patients with GIB and H. pylori were identified in AIS cohort. A stepwise multivariable logistic regression model was fitted to evaluate the outcome of upper GIB and role of H. Pylori in UGIB. Results: Overall 4,224,924 AIS hospitalizations were identified, out of which 18,629 (0.44%) had UGIB and 3122 (0.07%) had H. pylori. The prevalence of H. pylori-induced UGIB among UGIB in AIS was 3.05%. The prevalence of UGIB was markedly elevated among the H. pylori infection group (18.23% vs. 0.43%; p < 0.0001) compared to the non-H. pylori group. In multivariable regression analysis, H. pylori was associated with markedly elevated odds of UGIB (aOR:27.75; 95%CI: 21.07–36.55; p < 0.0001). Conclusion: H. pylori infection had increased risk-adjusted occurrence of UGIB amongst the AIS hospitalized patients. H. pylori testing may improve risk stratification for UGIB and lower the health care cost burden in stroke hospitalization.

Aim: To determine the prevalence of Helicobacter pylori infection and correlation between H. pylori infection and single nucleotide polymorphism (SNPs) identified in gastric cardia adenocarcinoma (GCA) patients. Methods: A case control study was performed. 22 risks of GCA-related SNPs were identified by genotyping assay and the relationship between susceptibility loci for GCA and H. pylori infection was further analyzed. Results: Helicobacter pylori infection was associated with GCA significantly (odds ratio: 1.40; 95% CI: 1.29–1.53 p < 0.01). Five GCA risk SNPs had their genotypes significantly different between H. pylori positive patients and H. pylori negative patients. Conclusion: The interaction between SNPs susceptibility loci and H. pylori infection is associated with an increased risk of GCA.

SUMMARYThe faecal-pat prevalence (as estimated by culture) ofCampylobacter fetusfrom cattle and sheep on 19 farms in rural Lancashire was investigated using standardCampylobacterculture techniques and PCR during a 2-year longitudinal study.C. fetuswas isolated from 9·48% [95% confidence interval (CI) 8·48–10·48] of cattle faecal pats and 7·29% (95% CI 6·21–9·62) of sheep faecal pats. There was evidence of significant differences in shedding prevalence between geographical regions; cows in geographical zone 3 had an increased risk of sheddingC. fetuscompared to cows in geographical zones 1 and 2 (OR 6·64, 95% CI 1·67–26·5,P = 0·007), as did cows at pasture (OR 1·66, 95% CI 1·01–2·73,P = 0·046) compared to when housed. Multiple logistic regression modelling demonstrated underlying seasonal periodicity in both species.
