Shen J, Ye Z, Xie H, Ling D, Wu Y, Chen Y. The relationship between Helicobacter pylori infection and recurrent aphthous stomatitis: a systematic review and meta-analysis. Clin Oral Investig 2023; 27:6345-6356. [PMID: 37798535 DOI: 10.1007/s00784-023-05273-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 09/19/2023] [Indexed: 10/07/2023]
Abstract
OBJECTIVE This meta-analysis was designed to provide new insights into the relationship between Helicobacter pylori (H. pylori) infection and recurrent aphthous stomatitis (RAS). MATERIALS AND METHODS We included and evaluated studies on H. pylori infection and RAS from PubMed, EMBASE, Cochrane Library, and Web of Science databases published up to January 31, 2023. The characteristics of these studies were collected, and the quality was evaluated by Newcastle-Ottawa Scale (NOS). The random effects model was used to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). To further explore the sources of heterogeneity, meta-regression analysis and subgroup analyses were performed. Funnel plot, Egger's test, and Begg's test were used to assess publication bias. RESULTS In total, fifteen case-control studies with 1137 individuals (601 cases and 536 controls) were included. The H. pylori was found to be significantly associated with RAS (OR: 1.83 95% CI: 1.41-2.37, P = 0.001). In the subgroup analyses, studies that used PCR (OR: 2.03 95% CI: 1.31-3.15) or UBT (OR: 1.83 95% CI: 1.13-2.96) yielded a significant positive association, while a non-significant association (OR: 1.12 95% CI: 0.61-2.08) was found from studies that used ELISA method. Sensitivity analyses showed that the results were robust. No significant publication bias was found. CONCLUSIONS The current evidence does not rule out an association between H. pylori and RAS. The effect of H. pylori on RAS varies in detection methods and sources of sample. Large samples, multiple clinical studies, and improved methods are still needed to determine the exact effect of H. pylori on RAS. CLINICAL SIGNIFICANCE H. pylori infection may be a risk factor for the pathogenesis of RAS.

Abstract
Oral cavity is an essential reservoir for H. pylori. We aimed to investigate the antibacterial effects of dimethylaminododecyl methacrylate (DMADDM) against H. pylori. Modified giomers were prepared by introducing 0%, 1.25% and 2.5% DMADDM monomers. Broth microdilution assay, spot assay, Alamer Blue assay, PMA-qPCR, crystal violet staining, scanning electron microscopy observation and live/dead bacterial staining were performed to evaluate the antibacterial and antibiofilm effects of DMADDM and modified giomers in vitro. Urease assay, qPCR, hematoxylin-eosin staining and ELISA were performed to evaluate the inflammation levels and colonization of H. pylori in vivo. In vitro experiments indicated that the minimum inhibitory concentration and minimum bactericidal concentration of DMADDM were 6.25 μg/mL and 25 μg/mL, respectively. It inhibited H. pylori in a dose- and time-dependent manner, and significantly reduced the expression of cagA, vacA, flaA and ureB. DMADDM-modified giomers inhibited the formation of H. pylori biofilm and reduced live cells within it. In vivo experiments confirmed that the pretreatment with DMADDM-modified dental resin effectively reduced the gastric colonization of oral-derived H. pylori, suppressed systemic and local gastric inflammation. DMADDM monomers and DMADDM-modified giomers possessed excellent antibacterial and antibiofilm effects on H. pylori. Pretreatment with DMADDM-modified giomers significantly inhibited the gastric infection by H. pylori.

Abstract
Background Porphyromonas gingivalis is part of the subgingival biofilm and a keystone species in the development of periodontitis. Interactions between P.gingivalis and other bacteria in biofilms have been shown to affect bacterial virulence. Helicobacter pylori also inhabits the subgingival biofilm, but the consequences of interactions there with P.gingivalis remain unknown. Here, we investigated how the pre-incubation of P.gingivalis with H.pylori affects P.gingivalis virulence. Methods We assayed P.gingivalis internalization by oral keratinocytes (OKs), hemagglutination and biofilm formation to identify alterations in virulence after pre-incubation with H. pylori. Also, we evaluated viability and migration of OKs infected with P. gingivalis, as well as the role of toll-like receptor 4 (TLR4). In addition, we quantified the mRNA of genes associated with P.gingivalis virulence. Results Pre-incubation of P.gingivalis with H.pylori enhanced P.gingivalis biofilm formation, bacterial internalization into OKs and hemagglutination. Infection with pre-incubated P.gingivalis increased OK migration in a manner dependent on the O-antigen and linked to increased expression of the gingipain RgpB. Also, OK TLR4 participates in these events, because upon TLR4 knock-down, pre-incubated P.gingivalis no longer stimulated OK migration. Discussion We provide here for the first time insight to the consequences of direct interaction between P.gingivalis and H.pylori. In doing so, we shed light on the mechanism by which H. pylori presence in the oral cavity increases the severity or progression of periodontitis.

Integrative Analysis of Deregulated miRNAs Reveals Candidate Molecular Mechanisms Linking H. pylori Infected Peptic Ulcer Disease with Periodontitis. DISEASE MARKERS 2022; 2022:1498525. [PMID: 35132337 PMCID: PMC8817886 DOI: 10.1155/2022/1498525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Accepted: 01/17/2022] [Indexed: 11/18/2022]
Abstract
Objective Periodontitis is a highly prevalent oral infectious disease and has been increasingly associated with H. pylori infection, gastric inflammation, and gastric cancer but little is known about epigenetic machinery underlying this potentially bidirectional association. The present study is aimed at identifying key deregulated miRNA, their associated genes, signaling pathways, and compounds linking periodontitis with H. pylori-associated peptic ulcer disease. Methods miRNA expression datasets for periodontitis-affected and H. pylori-associated peptic ulcer disease-affected tissues were sought from the GEO database. Differentially expressed miRNA (DEmiRNAs) were identified and the overlapping, shared-DEmiRNA between both datasets were determined. Shared-DEmiRNA-target networks construction and functional analyses were constructed using miRNet 2.0, including shared-DEmiRNA-gene, shared-DEmiRNA-transcription factor (TF), and shared-DEmiRNA-compound networks. Functional enrichment analysis for shared DEmiRNA-gene and shared DEmiRNA-TF networks was performed using the KEGG, Reactome, and Geno Ontology (GO) pathways. Results 11 shared-DEmiRNAs were identified, among which 9 showed similar expression patterns in both diseases, and 7 were overexpressed. miRNA hsa-hsa-mir-155-5p and hsa-mir-29a-3p were top miRNA nodes in both gene and TF networks. The topmost candidate miRNA-deregulated genes were PTEN, CCND1, MDM2, TNRC6A, and SCD while topmost deregulated TFs included STAT3, HIF1A, EZH2, CEBPA, and RUNX1. Curcumin, 5-fluorouracil, and the gallotanin 1,2,6-Tri-O-galloyl-beta-D-glucopyranose emerged as the most relevant linkage compound targets. Functional analyses revealed multiple cancer-associated pathways, PI3K pathways, kinase binding, and transcription factor binding among as enriched by the network-associated genes and TFs. Conclusion Integrative analysis of deregulated miRNAs revealed candidate molecular mechanisms comprising of top miRNA, their gene, and TF targets linking H. pylori-infected peptic ulcer disease with periodontitis and highlighted compounds targeting both diseases. These findings provide basis for directing future experimental research.

Abstract
AIM Periodontitis has been proposed to lead to Helicobacter pylori infection, which could cause many gastrointestinal tract cancers. This study aimed to determine the association or otherwise between periodontitis and survival outcomes in individuals with respect to H. pylori infection. MATERIALS AND METHODS The study population comprised 4955 subjects aged 20-90 who had received both periodontal examination and H. pylori serum test in the Third National Health and Nutrition Examination Survey (NHANES III) database. Logistic regression models were used to analyse the association between periodontitis and H. pylori seropositivity (H. pylori infection). Survival analysis was performed using the NHANES III linked to mortality data. Cox proportional hazard regression was carried out to investigate the association between periodontitis and gastrointestinal tract cancer mortality in individuals with/without H. pylori infection. RESULTS Compared to periodontal health, periodontitis was significantly associated with increased odds of H. pylori infection (OR = 1.271, 95% CI = 1.177-1.372). Periodontitis significantly increased the mortality risk from all causes (HR = 1.574, 95% CI = 1.327-1.866) and all cancers (HR = 1.948, 95% CI = 1.701-2.232), including gastrointestinal (GI) tract cancer (HR = 4.140, 95% CI = 3.656-4.687), gastric cancer (HR = 4.288, 95% CI = 3.969-4.632), and colorectal cancer (HR = 4.814, 95% CI = 3.849-6.020) in subjects with H. pylori infection after adjusting for health-related factors. Periodontitis was significantly related to the decreased survival time in subjects with GI tract (p = .001) or colorectal cancer (p = .002) and H. pylori infection. CONCLUSION Our study demonstrated that periodontitis was significantly associated with higher mortality risk of GI tract, gastric, and colorectal cancer in subjects with H. pylori infection. Owing to an interactive effect between periodontitis and H. pylori infection on cancer mortality, H. pylori infection has a significant moderating effect in regulating the association between periodontitis and mortality due to all cancers, including GI tract cancer and colorectal cancer.

Abstract
OBJECTIVE To establish a multiplex PCR-based method for detecting Helicobacter pylori (Hp) 16S rRNA gene and cagA gene in saliva samples for investigating the prevalence of Hp in the oral cavity of Hp-infected patients with digestive tract diseases. METHODS Bioinformatics technique was used to design specific primers for Hp 16S rRNA and cagA genes for Hp detection using multiplex PCR, with recombinant cloning plasmids serving as the standard positive control. Oral saliva samples were collected from 156 patients with digestive tract diseases, and Hp 16S rRNA and cagA genes were detected using the established multiplex PCR system. RESULTS The established multiplex PCR system showed a strong specificity and a high sensitivity for detecting Hp 16S rRNA gene and cagA gene, with the lowest detection limit of 103 copies/μL. The recombinant plasmids pGMT-16s and pGMT-cagA could be used as standard positive controls for the identification of Hp. Among the 156 saliva samples, 87.2% were positive for Hp 16S rRNA gene and 23.1% for Hp cagA gene. CONCLUSION Hp is highly prevalent in saliva specimens of Hp-infected patients with digestive tract diseases. The presence of Hp in the oral cavity may importantly contribute to Hp infection in the digestive tract and recurrence after treatment.

Abstract
Helicobacter pylori (H. pylori) eradication can reduce the risk of gastric diseases such as gastritis, gastric ulcer, and gastric adenocarcinoma. Since H. pylori was discovered more than 30 years ago, many studies have reported associations between H. pylori infection and extragastric diseases such as immune thrombocytopenia and iron-deficiency anemia. Thus, recent guidelines recommended H. pylori eradication in patients with those diseases. In contrast, although the role of H. pylori eradication in other extragastric diseases remains controversial, there is growing evidence of its benefit on them, especially cardiovascular (ischemic heart disease and stroke), metabolic (dyslipidemia, diabetes mellitus, and non-alcoholic fatty liver disease), neurodegenerative (Parkinson’s disease and Alzheimer’s disease), autoimmune (Graves’ disease, Hashimoto’s thyroiditis, Raynaud’s syndrome, rosacea, and chronic urticaria), and other (cap polyposis, colorectal mucosa-associated lymphoid tissue lymphoma, periodontal disease, hyperemesis gravidarum, and osteoporosis) conditions. A recent prospective randomized study reported that H. pylori eradication improved insulin resistance and dyslipidemia. These findings were consistent with the results of a recent meta-analysis. Therefore, well-designed prospective interventional studies are needed to examine the effects of H. pylori eradication on various extragastric diseases.

Abstract
Oral Potentially Malignant Disorders such as leukoplakia, lichenplanus, Oral Submucous Fibrosis are most commonly encountered precancerous lesions in India. Although, usage of smoking tobacco has been decreased yet incidence of oral cancer seems to be in increasing trend. Apart from tobacco many non-tobacco causes are associated with the disease. Helicobacter pylori is a curved, flagellated bacterium that has been declared as group I carcinogen by WHO. They are proven causative agent for gastric carcinoma. They have been shown to harbour oral cavity by many authours. They produce onco-protein that causes DNA damage. CagA and VacA are such proteins that modulate certain oncogenes and tumour suppressor genes. In this study we have identified the organism from sub gingival plaque by PCR and those who harboured the organism were further subjected for identification of oncoproteins CagA and VacA by ELISA. This study shows that presence of organism in Oral leucoplakia, oral lichenplanus and Oral Submucous Fibrosis are statistically significant in comparison to control group (p>0.05). The presence of oncoproteins was also statistically significant in comparison to control group. These proteins are shown to accelerate inflammatory pathway thereby hasten the process of tumorigenesis. H.pylori infection as well the virulent strains can be diagnosed from oral cavity in the most non-invasive way at the earliest.

Oral Microbiota and Salivary Levels of Oral Pathogens in Gastro-Intestinal Diseases: Current Knowledge and Exploratory Study. Microorganisms 2021; 9:microorganisms9051064. [PMID: 34069179 PMCID: PMC8156550 DOI: 10.3390/microorganisms9051064] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 05/11/2021] [Accepted: 05/12/2021] [Indexed: 12/23/2022] Open
Abstract
Various bi-directional associations exist between oral health and gastro-intestinal diseases. The oral microbiome plays a role in the gastro-intestinal carcinogenesis and fusobacteria are the most investigated bacteria involved. This paper aims to review the current knowledge and report the preliminary data on salivary levels of Fusobacterium nucleatum, Porphyromonas gingivalis and Candida albicans in subjects with different gastro-intestinal conditions or pathologies, in order to determine any differences. The null hypothesis was “subjects with different gastro-intestinal diseases do not show significant differences in the composition of the oral microbiota”. Twenty-one subjects undergoing esophagastroduodenoscopy or colonscopy were recruited. For each subject, a salivary sample was collected before the endoscopy procedure, immediately stored at −20 °C and subsequently used for genomic bacterial DNA extraction by real-time PCR. Low levels of F. nucleatum and P. gingivalis were peculiar in the oral microbiota in subjects affected by Helicobater pylori-negative chronic gastritis without cancerization and future studies will elucidate this association. The level of C. albicans did not statistically differ among groups. This preliminary study could be used in the future, following further investigation, as a non-invasive method for the search of gastrointestinal diseases and associated markers.

Abstract
Periodontitis is a complex immune-inflammatory condition characterized by the disruption of the periodontal ligament and subsequent formation of periodontal pockets, and by alveolar bone loss, often resulting in tooth loss. A myriad of factors, namely, genetic, metabolic, immunological, and inflammatory, is associated with progression of periodontitis. Periodontitis is also associated with systemic conditions such as neoplastic disorders, obesity, and diabetes. The current diagnosis of this disease relies on clinical measurements such as clinical attachment loss and probing depth, which have poor precision due to patient, operator and probe-related factors. Thus, there is a need to develop reliable, objective, and reproducible biomarkers for early diagnosis of periodontitis. In this regard, saliva, with contributions from the gingival crevicular fluid, holds great potential. However, most of the information on biomarkers of periodontium-related salivary proteins has come from studies on the molecular pathogenesis of periodontitis. In periodontitis, a more holistic approach, such as the use of -omics technologies, for biomarker discovery, is needed. Herein, we review the biomarkers proposed to date for the assessment of periodontitis, with emphasis on the role of salivary peptides in periodontitis and their assessment by high-throughput saliva proteomics. We also discuss the challenges pertaining to the identification of new periodontitis biomarkers in saliva.

Increased Risk of Migraine in Patients with Chronic Periodontitis: A Population-Based Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18041921. [PMID: 33671172 PMCID: PMC7922664 DOI: 10.3390/ijerph18041921] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/08/2021] [Accepted: 02/11/2021] [Indexed: 11/17/2022]
Abstract
Migraine is considered to be a neurovascular disease that manifests as a throbbing headache, possibly caused by the activation of the trigeminovascular system. Several studies have supported the role of inflammation in the pathogenesis of migraine. Chronic periodontitis (CP) is an infectious inflammatory disease triggered by bacterial products evoking an immune response which could result in the destruction of the periodontium. However, little is known about the longitudinal association between CP and migraine. In this study, we designed a nationwide population-based cohort study to investigate the risk of migraine and CP exposure in Taiwan. In total, 68,282 patients with CP were identified from the National Health Insurance Research Database (NHIRD), and 68,282 comparisons were randomly captured and matched by age, sex, monthly income, urbanization and comorbidities. The association between CP exposure and migraine risk was evaluated by Cox proportional hazards regression models. In this study, 785 migraine patients were identified in the CP cohort, and 641 migraine cases were found in the non-CP cohort. The incidence rate of migraine was significantly higher in the CP cohort than the non-CP cohort (adjusted HR: 1.21, 95% CI: 1.09–1.34, p < 0.001) during the 13-year follow-up period. Females had a 2.69-fold higher risk for migraine than males (95% CI: 2.38–3.04, p < 0.001). In summary, CP is associated with an increased risk of subsequent migraine in Taiwan.

Abstract
This review summarizes the recent knowledge on the epidemiology of Helicobacter pylori and the potential modes of transmission. In addition to English language publications, the authors have included original full-text publications from Russia and Latin America published in the original languages. High H pylori prevalence has been reported in Russia, Jordan, Iran, China, and Latin American countries as well as in Arctic populations in Canada. Indigenous inhabitants in the Arctic were found to be infected substantially more frequently than non-indigenous inhabitants. In Amsterdam, the Netherlands, the ethnic minority groups were at a significantly higher risk of being H pylori seropositive compared to the Dutch population. For the first time, data on the prevalence from Armenia have been published indicating 41.5% H pylori prevalence. Convincing evidence on the decline of H pylori prevalence in Southeast Hungary and Taiwan was published. A study from Chile suggested high infection rates in newborns during the first month after birth. Two meta-analyses covered the potential correlation between H pylori and periodontal diseases, therefore addressing the potential oro-oral transmission rates. Periodontal disease was found to be more prevalent in H pylori-infected subjects. Other studies addressed the potential role of drinking water and food products as well as socioeconomic factors in transmitting the infection. Several studies in Asia addressed annual reinfection rates of H pylori, ranging from 1.5% in China to 3.1% in Korea. Finally, a review was published on the current evidence and future perspective of analysing H pylori in ancient human remains by a metagenomic approach.

Abstract
Background/Aim: to examine the connection of H. Pylori in saliva and biopsy material with oral lesions. Material and Methods: Sixty patients with dyspeptic complaints were followed up at the Clinic for Gastroenterology at University Medical Clinical Centre in Skopje, divided into two groups: first group consisted of 30 patients without presence of H. pylori, and the second group with 30 subjects and presence of H. pylori. The presence or absence of H. pylori has been ascertained after endoscopic examination-gastroscopy, and implemented urease test (CLO-test). All patients were clinically followed in order to determinate mouth burning, recurrent aphthous stomatitis (RAS), acid taste and lingual papillary hyperplasia according to Cohen and Proctor. The presence of H. pylori in saliva has been ascertained before endoscopic examination, after chewing Orbit gum without sugar for 1 min using by Pronto dry test. Determination of H. pylori in biopsy material has been ascertained by rapid urease test (RUT). Results: At 30 patients with dyspeptic complaints and presence of Helicobacter pylori, 16 patients (53,33%) had lingual papillary hyperplasia, acid taste, burning mouth and recurrent aphthous stomatitis (RAS). At 4 patients (13,33%) was confirmed acid taste, and also at 4 patients (13,33%) burning mouth. At 2 patients (6,67%) was confirmed lingual papillary hyperplasia, burning mouth, and recurrent aphthous stomatitis (RAS). At the same time, at 2 patients (6,67%) was confirmed burning mouth, and recurrent aphthous stomatitis (RAS), until at 1 patient (3,33%) lingual papillary hyperplasia, as at 1 patient (3,33%) lingual papillary hyperplasia and acid taste. At patients without presence of Helicobacter pylori but with dyspeptic complaints, was confirmed burning mouth in 14 patients (46,67%), lingual papillary hyperplasia, burning mouth, and acid taste in 7 patients (23,33%); in 3 patients (10,00) lingual papillary hyperplasia, burning mouth, and in 2 patients (6,67%) was confirmed recurrent aphthous stomatitis (RAS). Acid taste was registered in 2 patients (6,67%), and also lingual papillary hyperplasia in 2 patients (6,67%). There was a significant differences in clinical aspect between the patients with and without presence of H. pylori, for p< 0,01(p= 0,002); Pearson Chi-square= 20,10 i and p<0,05(p= 0,01). Conclusions: H. pylori in saliva and biopsy material detected with CLO test are reason for oral lesions at patients with dyspeptic complaints who have the presence of H. pylori.
