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.

Abstract
Helicobacter pylori (H. pylori) is transmitted primarily through the oral–oral route and fecal–oral route. The oral cavity had therefore been hypothesized as an extragastric reservoir of H. pylori, owing to the presence of H. pylori DNA and particular antigens in distinct niches of the oral cavity. This bacterium in the oral cavity may contribute to the progression of periodontitis and is associated with a variety of oral diseases, gastric eradication failure, and reinfection. However, the conditions in the oral cavity do not appear to be ideal for H. pylori survival, and little is known about its biological function in the oral cavity. It is critical to clarify the survival strategies of H. pylori to better comprehend the role and function of this bacterium in the oral cavity. In this review, we attempt to analyze the evidence indicating the existence of living oral H. pylori, as well as potential survival strategies, including the formation of a favorable microenvironment, the interaction between H. pylori and oral microorganisms, and the transition to a non-growing state. Further research on oral H. pylori is necessary to develop improved therapies for the prevention and treatment of H. pylori infection.

Helicobacter pylori biofilms are disrupted by nanostructured lipid carriers: A path to eradication? J Control Release 2022; 348:489-498. [PMID: 35654169 DOI: 10.1016/j.jconrel.2022.05.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 05/24/2022] [Accepted: 05/26/2022] [Indexed: 11/20/2022]
Abstract
Bacterial biofilms account for 80% of all chronic infections, with cells being up to 1000 times more resistant to antibiotics than their planktonic counterparts. The recently discovered ability of Helicobacter pylori to form biofilms once again highlights why this bacterium is one of the most successful human pathogens. The current treatments failure rate reaches 40% of cases, emphasizing that new therapeutic options are a pressing need. Nanostructured lipid carriers (NLC), with and without docosahexaenoic acid (DHA), were very effective against H. pylori planktonic cells but their effect on H. pylori biofilms was unknown. Here, DHA-loaded NLC (DHA-NLC) and NLC without any drug (blank NLC) were tested on an optimized H. pylori in vitro floating mature biofilm model. DHA-NLC and blank NLC reduced the total biofilm biomass and had a bactericidal effect against both biofilm and planktonic bacteria in all the concentrations tested (0.125-2 mg/mL). DHA-NLC achieved biofilm biomass reduction in a concentration ~ 8 times lower than blank NLC (0.125 vs 1 mg/mL, respectively). Both NLC were bactericidal at the lowest concentration tested (0.125 mg/mL) although with different efficiency, i.e. a decrease of ∼6 log10 for DHA-NLC and ∼5 log10 for blank NLC. In addition, the equivalent amount of free DHA (3.1 μM) only reduced bacterial viability in ∼2 log10, demonstrating the synergistic effect of DHA and NLC in the treatment of H. pylori biofilms. Nevertheless, although viable bacteria were not detected by colony forming unit (CFU) counting after treatment with both NLC, confocal microscopy imaging highlighted that some H. pylori cells remained alive. In addition, scanning electron microscopy (SEM) analysis confirmed an increase in bacteria with a coccoid morphology after treatment, suggesting a transition to a viable but non-culturable (VBNC) state. Altogether, it is herein established that NLC, even without any drug, are promising for the management of H. pylori bacteria organized in biofilms, opening new perspectives for the eradication of this gastric pathogen.

Abstract
Some research has suggested that dental plaque and saliva could be reservoirs of Helicobacter pylori (H. pylori) and be capable of infecting or re-infecting the gastric mucosa after eradication, with certain studies showing a significant association between PD and gastric infection by this bacterium. An electronic search was performed in PubMed, EMBASE, and Web of Science databases with the terms “Helicobacter pylori AND periodontal diseases”; “Helicobacter pylori AND gingivitis”; “Helicobacter pylori AND chronic periodontitis”; “Helicobacter pylori AND periodontitis”; “Helicobacter pylori AND dental plaque”, to identify articles up to September 2021. The Newcastle-Ottawa scale was used to assess study quality. A meta-analysis was performed using RevMan 2020 (Cochane Collaboration) software. A total of 1,315 studies were identified and 12 were included, analyzing 226,086 patients with mean age between 10.5 and 63.4 years. The prevalence of H. pylori in the oral cavity ranged from 5.4 to 83.3%. A random-effects model was used to analyze the presence of H. pylori and subgroups were made according to the method of evaluation (PCR or RUT). Statistical significance was found in the overall analysis (p = 0.01). There is no clear evidence that H. pylori present in oral bacterial plaque causes gastric infection and vice versa.

Abstract
OBJECTIVE To identify Helicobacter pylori (H.pylori) and related oncogenic and virulent proteins (CagA and VacA) in patients with gingivitis, periodontitis, oral cancer and gastric cancer. METHODS Subgingival plaque samples were collected from 90 individuals with either gingivitis/ periodontitis (group A, n=30), oral cancer (group B, n=30) and gastric cancer (group C, n=30). H.pylori was identified by real time- polymerase chain reaction (RT-PCR). The virulent organisms were detected by identification of proteins CagA and VacA through Enzyme Linked Immuno Sorbent Assay (ELISA). RESULTS We identified the presence of H.pylori in subgingival plaque samples among a large majority (76/90) of our study cohort. The proportions of CagA and VacA identified among H.pylori individuals with periodontal inflammation and oral cancer were lower than those diagnosed with gastric cancer. Furthermore, the relative risk of oral cancer based on the presence of the organism was no different to those with gingivitis/periodontitis. CONCLUSION The findings of our study does not indicate significant association between the organism and oral cancer but preludes that the oral cavity could act as a potential niche for H.pylori. The possibility for CagA and VacA proteins to be pathogenic in oral cavity is highly possible and to be researched extensively.

Abstract
OBJECTIVE To evaluate the general population's awareness of and attitudes toward Helicobacter pylori (HP) screening and health behaviours. DESIGN Cross-sectional study. SETTING Hengyang, Hunan Province, China. PARTICIPANTS Using stratified cluster random sampling, a pretested structured questionnaire was used to interview members of the general population aged ≥18 years. PRIMARY AND SECONDARY OUTCOME MEASURES Knowledge of and attitudes toward HP screening and associated health behaviours, sociodemographic factors associated with HP knowledge, and screening behaviours. RESULTS This study featured 1042 participants. The average knowledge score was 11 (QL=4, QU=20, range 0-29). Approximately 68.9% of the participants said they had heard of HP, but 67.5% had never had an HP test. The most common reasons for not undergoing screening were 'no symptoms' (55.7%) and 'lack of knowledge regarding the benefits of the test' (21.1%). Independent factors related to knowledge included age, education level, occupation, HP infection, frequency of drinking unboiled water (p<0.05). Factors independently associated with screening behaviour included occupation, average monthly income, presence/absence of indigestion, stomach discomfort or pain, and/or stomach disease and knowledge score (p<0.05). Overall, 941 (90.3%) participants never used anti-HP toothpaste, and 442 (40.5%) never used serving spoons or chopsticks. The risk factors for HP infection included eating out and eating in groups (p<0.05). CONCLUSION In China, the general population has poor knowledge of HP, but most people have a positive attitude towards HP screening. Being asymptomatic and lacking knowledge about testing were the main reasons for reluctance to be screened. These results highlight the urgent need for educational activities to raise awareness, enhance screening rates for HP, and encourage people to adopt a healthy lifestyle.

Abstract
Aim In this review, several gastrointestinal diseases that dentists may encounter in practice are highlighted and discussed. Materials and methods Using MEDLINE (PubMed), a comprehensive review of gastrointestinal diseases and their oral cavity manifestations was performed. Results Many gastrointestinal diseases present with oral symptoms that are detectable by dentists and dental hygienists. Often, oral manifestations of the disease may appear before systemic signs and symptoms. Managing patients with these conditions requires dentists to adjust their treatment and/or involve other health professionals. Conclusion Care must be taken when providing periodontal therapy or dental implants to patients suffering gastrointestinal diseases who are at high risk of bleeding, infection, or malnutrition, for example. Also, pharmacological therapy for these patients may need to be customized.

Abstract
Objectives The efficacy of conventional systemic antibiotic therapy for eradication of Helicobacter pylori has been seriously challenged by antibiotic resistance. Identification of alternative therapeutic strategies might help to overcome this limitation. The aim of this study was to update previous meta-analyses that investigated the effect of periodontal treatment on gastric H. pylori eradication. Methods A systematic electronic search of the literature was conducted to identify all published clinical trials that compared the effect of adjunct periodontal treatment on conventional systemic H. pylori eradication therapy. Results The updated analysis (consisting of 541 participants representing six studies) demonstrated that, compared with conventional systemic eradication therapy alone, the addition of periodontal treatment resulted in improvements in gastric H. pylori eradication rates with OR 4.11 (P = 0.01). Moreover, not to lose any data, the previously presented Chinese results that could not be assessed by any available mechanism deduced from previously published meta-analysis and with other records were re-analysed. Similarly, the second meta-analysis adding up to a final cluster of 10 studies (909 participants) gives further credence to periodontal treatment as a useful concomitant therapy in the H. pylori eradication therapy (odds ratio [OR] = 2.65; P = 0.0002). Finally, the meta-analysis of four trials consisting of 177 cases and 161 controls showed that periodontal treatment also improved non-recurrence rates of gastric H. pylori infection, with an OR of 5.36 (P-value = 0.0002). Conclusion Although the inclusion of five additional clinical trials in this updated meta-analysis has not changed the result of the previous review, the current meta-analysis is superior for having removed one study involving the use of chlorhexidine, which did not meet appropriate criteria for inclusion. Our results strengthen the value of periodontal treatment as an adjunctive remedy. Consistency of these results suggests that the incorporation of professional periodontal treatment with systemic eradication therapy may be a wise strategy, enhancing the efficacy of H. pylori eradication therapy.

Abstract
Helicobacter pylori (HP) infection is an established causative agent for gastric cancer. Although the oral cavity is a part of the gastrointestinal system, the presence and possible causative role of HP in oral squamous cell carcinoma (OSCC) is a subject of controversy. Therefore, the current study aimed to investigate HP infection in two cohorts of OSCC patients with different demographic characteristics, lifestyles and habitual risk factors. A total of 242 formalin-fixed paraffin-embedded OSCC specimens from two different patient cohorts (Norway, n = 171 and Nepal, n = 71) were used to examine HP using immunohistochemistry (IHC) and quantitative polymerase chain reaction (qPCR). Two different HP specific genes (23S rRNA and ureA) were used for TaqMan-based qPCR, and for subsequent verification using HP specific RIDAGENE HP kit and SYBR Green based qPCR. All of the OSCC specimens from both cohorts were found to be negative for HP infection with IHC and qPCR, although the positive control specimens tested positive. Our findings suggest that HP is absent in the examined OSCC cohorts, irrespective of race, lifestyle and habitual risk factors. This indicates that, in contrast to gastric cancer, HP is an unlikely contributing factor for OSCC pathogenesis.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is well-known for its role in chronic gastritis and gastric cancer. Eradication of these carcinogenic bacteria from the gut is one of the challenges for clinicians. The complexity of treatment mainly owes to antibiotic resistance and relapse due to an additional reservoir in the oral cavity. Our study emphases the isolation of H. pylori from distinct habitats of the gut microenvironment (gastric biopsy and gastric juice) and its subsequent characterization. We have also evaluated the effect of various oral rinses on isolated H. pylori from different anatomical locations of included subjects. RESULTS The possible strains isolated from two different habitats of the same subject shows a striking difference in their growth pattern. Promisingly, some of the included oral rinses are efficient in growth inhibition as per recommended 30 s treatment. The subsequent evaluation shows that oral rinse B (among A-E) is most effective and down-regulates the expression of one of the potent H. pylori gene, CagA, in the infected gastric adenocarcinoma (AGS) cells. CONCLUSION Our study, for the first time, revealed that H. pylori, isolated from the different habitat of the same subject, show a different growth pattern. The expression of H. pylori pathogenic gene (CagA) was down-regulated by the use of oral rinses. Hence, oral rinses will reduce the H. pylori in the oral cavity and help to control its migration from oral to the gastric compartment and may be used as an adjuvant treatment option for its re-infection.

Abstract
BACKGROUND Epidemiological studies have shown that gastrointestinal Helicobacter pylori (H. pylori) infection is the main cause of chronic gastritis, but the relation between oral H. pylori and chronic periodontitis (CP) remains uncertain. A meta-analysis of published papers was performed to elucidate the correlation between oral H. pylori and CP. METHOD To perform this meta-analysis, we searched papers published from 2000 to 2018 on PubMed, OVID, Springer Link, Chinese National Knowledge Infrastructure (CNKI) and Chinese Biology Medicine search engines. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) for the correlation between H. pylori and CP were estimated. Heterogeneity, publication bias and subgroup analyses were also conducted. RESULTS A total of 918 papers on oral H. pylori and CP were collected, and 11 papers were in accordance with the inclusion criteria. Oral H. pylori was suggested to be correlated with CP. The results indicated that a H. pylori-positive state significantly increased the risk of CP 3.42 times (OR = 3.42; 95% CI = 2.71-4.31). A diagnostic test using polymerase chain reaction (PCR) showed a higher prevalence of H. pylori (OR = 3.70; 95% CI = 2.66-5.14) than did that using the rapid urease test (RUT) (OR = 3.13; 95% CI = 2.26-4.34). CONCLUSIONS This paper demonstrated that CP was potentially correlated with oral H. pylori in adults and that oral H. pylori may be a possible risk factor for CP.

Abstract
OBJECTIVE To investigate the potential effect of chronic atrophic gastritis on chronic periodontitis and further explore the possible mechanism. METHODS Local periodontal lesions were collected from periodontitis tissues of 30 CAG patients and 35 control adults without CAG (non-CAG). Clinical periodontal parameters were recorded, and the expression levels of distinct CD4+ Th specific cytokines at local periodontitis lesions were evaluated by real time PCR (RT-PCR). Helicobacter pylori (H. pylori) detection was carried out in both gastric and periodontitis lesions of CAG and non CAG patients. RESULTS Clinical parameters analysis showed that the level of clinical attachment loss in periodontitis lesions of CAG group was significantly higher than non-CAG group. It was observed that the infection rate of H. pylori in the CAG group was higher than non-CAG group. Further cytokine analysis showed that Th17 associated cytokines IL-17, IL-21 and IL-23 were increased in periodontal lesions of CAG patients when compared with non-CAG patients. However, Th1, Th2, Th9 and Treg cells specific cytokines were not significantly increased in CAG group when compared with non-CAG group. CONCLUSIONS Patients with CAG demonstrated that significant elevated attachment loss in periodontitis lesions, while elevated Th17 cytokines IL-17, IL-21 and IL-23 participate in immunopathogenesis of both diseases.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common infection in humans, affecting more than half of the population. The prevalence of the infection varies widely in rural developing areas (more than 80%) compared to urban developed ones (less than 40%), as a consequence of different socioeconomic and hygienic conditions. H. pylori infection is usually acquired during childhood; infected people usually remain asymptomatic, but about 30% of individuals may develop mild to severe upper gastrointestinal diseases such as gastritis, peptic ulcer, gastric cancer or MALT lymphoma. The transmission route is not clear yet; the person-to-person transmission, especially within the same family appears to be prevalent, but also environmental contamination is possible. The eradication without a specific therapeutic regimen is very unlikely and the reinfection rate after an effective eradication therapy is quite rare. The reinfection rate will increase if there are family members affected.

Abstract
AbstractHelicobacter pylori(Hp) is one of the most common human pathogens. The infection caused by this bacterium is closely related to various clinical diseases. However, the eradication rate of conventional quadruple therapy has decreased, but the recurrence rate of infections has increased. The oral cavity is another major storage of Hp in addition to the stomach, and a certain homology exists between Hp in the oral cavity and Hp in the stomach. Periodontal treatment has a certain role in the killing of oral Hp, which can increase the eradication rate and reduce the recurrence rate of Hp in the stomach. This article summarizes the influence of oral Hp on the eradication rate and recurrence rate of gastric Hp.

Abstract
Dental caries is a chronic progressive disease occurring in the tooth hard tissue due to multiple factors, in which bacteria are the initial cause. Both Streptococcus mutans and Streptococcus sanguinis are main members of oral biofilm. Helicobacter pylori may also be detected in dental plaque, playing an important role in the development of dental caries. OBJECTIVE The aim of this study was to investigate the effect of H. pylori culture supernatant on S. mutans and S. sanguinis dual-species biofilm and to evaluate its potential ability on affecting dental health. MATERIAL AND METHODS The effect of H. pylori supernatant on single-species and dual-species biofilm was measured by colony forming units counting and fluorescence in situ hybridization (FISH) assay, respectively. The effect of H. pylori supernatant on S. mutans and S. sanguinis extracellular polysaccharides (EPS) production was measured by both confocal laser scanning microscopy observation and anthrone-sulfuric acid method. The effect of H. pylori supernatant on S. mutans gene expression was measured by quantitative real-time PCR (qRT-PCR) assays. RESULTS H. pylori supernatant could inhibit both S. mutans and S. sanguinis biofilm formation and EPS production. S. sanguinis inhibition rate was significantly higher than that of S. mutans. Finally, S. mutans bacteriocin and acidogenicity related genes expression were affected by H. pylori culture supernatant. CONCLUSION Our results showed that H. pylori could destroy the balance between S. mutans and S. sanguinis in oral biofilm, creating an advantageous environment for S. mutans, which became the dominant bacteria, promoting the formation and development of dental caries.

Abstract
Urea breath test (UBT), as a leading preferred non-invasive diagnostic technology, but may not be able to detect oral H. pylori. With negative results of UBT, the patient may have an oral infection. On the basis of the fact of success, eradication rate may increase by 21% in the 95% Cl range after the elimination of oral H. pylori, the author believes oral H. pylori does exist and the oral cavity is the second colonized site aside its primary site of the stomach. H. pylori migrated out of Africa along with its human host circa 60 000 years ago; they are not lives in stomach only. In this review article, evidence established in recent years studies with use more appropriate technology had been listed and discussed. The author considers the oral cavity is a black hole for H. pylori infection that significant effective on gastroenterology and another medical field. The role of the oral cavity as the source of H. pylori infection is so controvert in past years. It seems like a human being having a second-time face to discover H. pylori in the history.

Abstract
BACKGROUND
Many studies have reported an association between periodontal infections and some systemic diseases such as respiratory and cardiovascular diseases. Some studies found a direct association between chronic gastritis caused by Helicobacter pylori (HP) infection and poor periodontal health.
METHODS
In a cross-sectional study from November 2014 to December 2015 in Kerman, the largest province in southeast Iran, patients with dyspepsia who were candidate for diagnostic upper gastrointestinal (GI) endoscopy were included in our study. Decayed, Missing, and Filled Teeth (DMFT) index and Loe plaque index that are two popular indexes in dental epidemiology were used to assess the oral health by a dentist before the upper GI endoscopy. According to the Loe plaque index, score: 0= no plaque, score: 1= a film of plaque attaching to the free gingival border and near area of the tooth, score: 2= moderate reposition of deposits within the gingival pocket, score :3= plenty of soft matter within the gingival pocket±on the tooth and gingival border. Scores ≤1, 2 and 3 equal to good, moderate, and poor oral hygiene, respectively. During upper GI endoscopy a total of six biopsy samples were taken from fundus, body, and antrum. A pathologist reported these samples according to Sidney’s classification into superficial gastritis, atrophic gastritis, intestinal metaplasia, and dysplasia.
RESULTS
According to Sidney’s classification 77 (89.5%) patients had superficial gastritis, 3 (3.5%) had atrophic gastritis, and 6 (7%) had intestinal metaplasia. HP was found in 80.2% of the gastric mucosal biopsy samples. There were not statistically significant relationship between Sidney’s classification, presence of HP in gastric mucosal biopsies, and hygiene indicators (p>0.05). No relation was found between the DMFT index and superficial gastritis, atrophic gastritis, and intestinal metaplasia (p>0.05). Gastric infection with HP was found in 70%, 75%, and 100% of patients with mild, moderate, and sever DMFT index, respectively.
CONCLUSION
Our study showed that there might be a relation between poor oral hygiene and gastric precancerous lesions. In addition, HP infection in gastric histopathology might be associated with periodontal disease.

Abstract
BACKGROUND Helicobacter pylori is estimated to affect about half the world's population and is considered as the main cause of chronic gastritis and peptic ulcer disease. Eradication of H. pylori infection accelerates ulcer healing and prevents relapse, reducing incidence of H. pylori-related gastric diseases. Numerous studies have provided evidence that the oral cavity could be a potential reservoir for H. pylori. The presence of oralH. pylori might affect the efficiency of eradication therapy and act as a causal force for its recurrence. Conversely, other investigators have indicated that the colonization and growth of H. pylori differs between the oral cavity and the stomach. Considering the open debate on the topic, it's necessary to clarify whether periodontal therapy is an effective adjunctive treatment for gastric H. pylori infection. OBJECTIVES To assess the effects of periodontal therapy plus eradication therapy versus eradication therapy alone for gastric H. pylori infection. The secondary objective is to compare the non-recurrence rate at long-term follow up in different treatment groups. SEARCH METHODS We identified randomized controlled trials (RCTs) by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 8), MEDLINE (1946 to August 2015), EMBASE (1980 to August 2015), and the Chinese Biomedical Database (1978 to August 2015). We also searched both ClinicalTrials.gov and the WHO ICTRP portal in October 2015. We handsearched the reference lists of included studies to identify relevant trials. SELECTION CRITERIA RCTs comparing periodontal therapy plus eradication treatment with eradication treatment alone, regardless of language of publication. DATA COLLECTION AND ANALYSIS Two reviewers selected the trials that met the inclusion criteria and extracted the details of each study independently. The data were pooled using both fixed-effect and random-effects models and results calculated as odds ratios (OR) with their 95% confidence intervals (CIs) based on an intention-to-treat analysis. However, because there was little difference in the results from these two models, we only reported the results from the fixed-effect model. MAIN RESULTS We included seven small RCTs involving 691 participants aged 17 to 78 years in our meta analyses. The primary result showed that periodontal therapy combined with H. pylori eradication treatment increased the eradication rate of gastric H. pylori compared with eradication treatment alone (OR 2.15; 95% CI 1.47 to 3.14; P < 0.0001) in people with H. pylori infection. In addition, periodontal therapy also had benefits on long-term gastric H. pylori eradication. After eradication of H. pylori, the non-recurrence rate of gastric H. pylori infection increased in participants treated with periodontal therapy compared with those who received eradication therapy alone (OR 3.60; 95% CI 2.11 to 6.15; P < 0.00001). According to the GRADE approach, the overall quality of the evidence was 'moderate' for eradication rate of gastric H.pylori and 'low' for non-recurrence rate of gastric H. pylori. AUTHORS' CONCLUSIONS Overall, periodontal therapy could increase the efficiency of H. pylori eradication and the non-recurrence rate of gastricH. pylori. In view of the limited number and quality of included studies, it will be necessary to conduct more well-designed, multicenter, and large-scale RCTs to determine the effects of periodontal therapy in eradicating gastric H. pylori and suppressing the recurrence of this bacterium in the stomach.

Abstract
BACKGROUND Sequencing of 16S ribosomal RNA (rRNA) gene has improved the characterization of microbial communities. It enabled the detection of low abundance gastric Helicobacter pylori sequences even in subjects that were found to be H. pylori negative with conventional methods. The objective of this study was to obtain a cutoff value for H. pylori colonization in gastric mucosa samples by pyrosequencing method. MATERIALS AND METHODS Gastric mucosal biopsies were taken from 63 subjects whose H. pylori status was determined by a combination of serology, rapid urease test, culture, and histology. Microbial DNA from mucosal samples was amplified by PCR using universal bacterial primers. 16S rDNA amplicons were pyrosequenced. ROC curve analysis was performed to determine the cutoff value for H. pylori colonization by pyrosequencing. In addition, temporal changes in the stomach microbiota were observed in eight initially H. pylori-positive and eight H. pylori-negative subjects at a single time point 1-8 years later. RESULTS Of the 63 subjects, the presence of H. pylori sequences was detected in all (28/28) conventionally H. pylori-positive samples and in 60% (21/35) of H. pylori-negative samples. The average percent of H. pylori reads in each sample was 0.67 ± 1.09% in the H. pylori-negative group. Cutoff value for clinically positive H. pylori status was approximately 1.22% based on ROC curve analysis (AUC = 0.957; p < .001). Helicobacter pylori was successfully eradicated in five of seven treated H. pylori-positive subjects (71.4%), and the percentage of H. pylori reads in these five subjects dropped from 1.3-95.18% to 0-0.16% after eradication. CONCLUSION These results suggest that the cutoff value of H. pylori sequence percentage for H. pylori colonization by pyrosequencing could be set at approximately 1%. It might be helpful to analyze gastric microbiota related to H. pylori sequence status.

Abstract
OBJECTIVE To investigate the incidence of oral infection with Helicobacter pylori (H. pylori) and identify related epidemiological factors among freshmen of four colleges in Yancheng. METHODS The data, scored positive or negative, were collected on 160 individuals who had been diagnosed by H. pylori Saliva Test Cassette (HPS) during October 2013 to October 2014. H. pylori Saliva Test Cassette (HPS) is to use colloidal gold technique to specifically identify urease in saliva. A standard questionnaire, with variables including sex, educational degree of parents etc., was used in the subjects. Statistical data of diagnostic test were analyzed by SPSS17.0 software. RESULTS Out of 160, 82 subjects were detected positive and 78 were negative. In univariate analysis, dental plaque, family history of stomach diseases, habit of washing hands before meals and habit of brushing teeth twice daily were associated negatively with H. pylori infection. Multivariate logistic regression analysis showed that dental plaque and family history of stomach diseases were the risk factors which may be associated with H. pylori infection. CONCLUSIONS Dental plaque and family history of gastric diseases were risk factors of oral H. pylori infection. It is vital for the prevention of H. pylori infection to focus on health education and oral hygiene, and avoid transmission by oral-oral route as well.

Abstract
Helicobacter pylori (H. pylori) has been found in the oral cavity and stomach, and its infection is one of the most frequent worldwide. We reviewed the literature and conducted a Topic Highlight, which identified studies reporting an association between H. pylori-infection in the oral cavity and H. pylori-positive stomach bacterium. This work was designed to determine whether H. pylori is the etiologic agent in periodontal disease, recurrent aphthous stomatitis (RAS), squamous cell carcinoma, burning and halitosis. Record selection focused on the highest quality studies and meta-analyses. We selected 48 articles reporting on the association between saliva and plaque and H. pylori-infection. In order to assess periodontal disease data, we included 12 clinical trials and 1 meta-analysis. We evaluated 13 published articles that addressed the potential association with RAS, and 6 with squamous cell carcinoma. Fourteen publications focused on our questions on burning and halitosis. There is a close relation between H. pylori infection in the oral cavity and the stomach. The mouth is the first extra-gastric reservoir. Regarding the role of H. pylori in the etiology of squamous cell carcinoma, no evidence is still available.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common bacterial infections in humans. Although H. pylori may be detected in the stomach of approximately half of the world's population, the mechanisms of transmission of the microorganism from individual to individual are not yet clear. Transmission of H. pylori could occur through iatrogenic, fecal-oral, and oral-oral routes, and through food and water. The microorganism may be transmitted orally and has been detected in dental plaque and saliva. However, the role of the oral cavity in the transmission and recurrence of H. pylori infection has been the subject of debate. A large number of studies investigating the role of oral hygiene and periodontal disease in H. pylori infection have varied significantly in terms of their methodology and sample population, resulting in a wide variation in the reported results. Nevertheless, recent studies have not only shown that the microorganism can be detected fairly consistently from the oral cavity but also demonstrated that the chances of recurrence of H. pylori infection is more likely among patients who harbor the organism in the oral cavity. Furthermore, initial results from clinical trials have shown that H. pylori-positive dyspeptic patients may benefit from periodontal therapy. This paper attempts to review the current body of evidence regarding the role of dental plaque, saliva, and periodontal disease in H. pylori infection.

Abstract
Background. Several studies were reported on the prevalence, and relationship between the existence of Helicobacter pylori (H. pylori) in oral cavity and in stomach of patients. The purpose of this study was to systematically review the existing literature on the presence of H. pylori in the oral cavity and its link to gastric infection, the existence of coinfection, and the impact of anti-H. pylori therapy on the dental plaque and vice versa. Method. Two authors independently searched the Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies. The articles were analyzed critically and all qualified studies were included. The search was carried out by using a combined text and the MeSH search strategies: using the key words Helicobacter, Helicobacter pylori, and H. pylori in combination with dental plaque, periodontitis, and oral hygiene. Results. The data was presented in 8 tables and each topic separately discussed. Conclusion. Based on the systematic review of the available literature on H. pylori infection and its presence in the oral cavity, it can be concluded that dental plaque can act as a reservoir, and proper oral hygiene maintenance is essential to prevent reinfection. Due to the diversified methods and population groups involved in the available literature, no concrete evidence can be laid down. Further studies are necessary to establish the role of H. pylori in the oral cavity and its eradication on preventing the gastroduodenal infection.

Abstract
Background and aims. The high prevalence of Helicobacter pylori among the microorganisms isolated from the oral environment brings up the question of whether oral cavity acts as a reservoir for this bacterium. The aim of the present study was to determine and compare the prevalence of H. pylori in gingival crevicular fluid (GCF) of patients with chronic periodontitis (CP) as an infectious disease and healthy subjects using polymerase chain reaction (PCR).
Materials and methods. Periodontal examination was performed for all participants. Two sterilized paper points were inserted to the maximum depth of the periodontal pockets of selected teeth. The presence of H. pylori was determined by PCR. In the CP group, the severity of disease was defined as moderate or severe. Further, the frequency of Helicobacter pylori in GCF of each category, and the association between the presence of Helicobacter pylori in GCF and periodontitis were determined.
Results. There was no statistically significant association between CP and the presence of H. pylori in the GCF (P = 0.62), there was no significant correlation between the presence of H. pylori in the GCF and gender of the subjects (P = 0.28 in CP group and P = 0.25 in control group), and there was no significant correlation between the presence of H. pylori in the GCF and severity of periodontitis (P = 0.20).
Conclusion. Oral cavity acts as a reservoir for H. pylori; however, the results do not show that H. pylori is involved in periodontal disease.

Abstract
Epithelial cells in oral cavities can be considered reservoirs for a variety of bacterial species. A polymicrobial intracellular flora associated with periodontal disease has been demonstrated in buccal cells. Important aetiological agents of systemic and nosocomial infections have been detected in the microbiota of subgingival biofilm, especially in individuals with periodontal disease. However, non-oral pathogens internalized in oral epithelial cells and their relationship with periodontal status are poorly understood. The purpose of this study was to detect opportunistic species within buccal and gingival crevice epithelial cells collected from subjects with periodontitis or individuals with good periodontal health, and to associate their prevalence with periodontal clinical status. Quantitative detection of total bacteria and Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus faecalis in oral epithelial cells was determined by quantitative real-time PCR using universal and species-specific primer sets. Intracellular bacteria were visualized by confocal microscopy and fluorescence in situ hybridization. Overall, 33% of cell samples from patients with periodontitis contained at least one opportunistic species, compared with 15% of samples from healthy individuals. E. faecalis was the most prevalent species found in oral epithelial cells (detected in 20.6% of patients with periodontitis, P = 0.03 versus healthy individuals) and was detected only in cells from patients with periodontitis. Quantitative real-time PCR showed that high levels of P. aeruginosa and S. aureus were present in both the periodontitis and healthy groups. However, the proportion of these species was significantly higher in epithelial cells of subjects with periodontitis compared with healthy individuals (P = 0.016 for P. aeruginosa and P = 0.047 for S. aureus). Although E. faecalis and P. aeruginosa were detected in 57% and 50% of patients, respectively, with probing depth and clinical attachment level ≥6 mm, no correlation was found with age, sex, bleeding on probing or the presence of supragingival biofilm. The prevalence of these pathogens in epithelial cells is correlated with the state of periodontal disease.

Abstract
AIM The aim of this review is to assess the effect of dental plaque control and periodontal therapy on prevention of gastric Helicobacter pylori (H. pylori) recurrence. MATERIALS AND METHODS We conducted searches of electronic databases, and included controlled trials comparing periodontal treatment and eradication therapy of H. pylori with eradication therapy alone for prevention of recurrence of gastric H. pylori. We used the absence of recurrence of gastric H. pylori after the first 3 months as an outcome measure to determine relative risk of persistence of gastric H. pylori. We estimated the degree of heterogeneity among trial results using Q and I(2) statistics. RESULTS Three trials including 298 patients were eligible according to our inclusion criteria. As significant heterogeneity was indicated by the Q statistics (p = 0.04) and I(2) (69%), we used a random-effects model to combine the data. Compared with eradication therapy alone, the adjunction of periodontal therapy significantly reduced the relative risk of persistence of gastric H. pylori by 63% (0.37 [95% CI 0.21-0.64], p = 0.0004) in patients with gastric diseases. CONCLUSIONS The adjunction of periodontal treatment to eradication therapy appears to reduce gastric H. pylori recurrence compared with eradication therapy alone among patients with gastric diseases associated with H. pylori. The results of this meta-analysis should be taken with caution because of the limitations in the primary data.

Abstract
BACKGROUND Approximately 15% of human deaths from cancer are associated with chronic viral or bacterial infections. Helicobacter pylori (HP), a flagellated, Gram-negative, spiral, microaerophilic bacteria is considered to be the most common chronic bacterial infection in humans. Toll-like receptor 5 (TLR5) is involved in recognition of bacterial flagella and is thought to promote tumour growth through inflammation-dependent mechanisms in epithelial cells. METHODS Expression of HP and TLR5 was analysed in OSCC specimen (n = 191) by immunohistochemistry. TLR5 expression specificity was conducted by Western blotting in cancer cell lines (BICR3, BICR56). TLR5-stained sections were scanned and digitally analysed using ImageJ and the immunomembrane plug-in. HP expression and TLR5 expression were associated with clinicopathological characteristics and impact on survival. RESULTS Helicobacter pylori detection was significantly associated with recurrence of the tumour, whereas TLR5 expression was not. Multivariate analysis demonstrated HP expression as an independent prognostic factor (P = 0.0260). TLR5 specificity was confirmed by Western blot analysis. CONCLUSIONS For the first time, this study provides evidence that immunohistochemically detected HP expression in OSCC is associated with reduced disease-free survival in a large patient cohort. Although TLR5 was not associated with any clinicopathological characteristics or impact on survival, investigation of the TLR family seems to be reasonable due to the possible existence of other pathogenic bacterial or viral compounds in oral cavity cancer.

Abstract
BACKGROUND Helicobacter pylori is an important gastrointestinal pathogen that is strongly associated with gastritis as well as peptic ulcer disease. Antimicrobial therapy frequently fails to cure H. pylori infection, which suggests there may be sanctuary sites where the organism resides. This study was aimed to assess the role of oral cavity as a reservoir of H. pylori by evaluating the occurrence of the organism in subgingival plaque of dyspeptic patients by polymerase chain reaction as well as culture. MATERIALS AND METHODS Thirty chronic periodontitis patients whose biopsy specimens were found to be H. pylori positive with rapid urease test and histopathologic examination were considered as cases and 20 chronic periodontitis patients who never had any symptoms of gastritis or peptic ulcer were taken as controls. Subgingival plaque samples were collected and sent to microbiological laboratory for detection of H. pylori by 16S rRNA based polymerase chain reaction as well as culture. RESULTS 60% of the samples were found to be positive with polymerase chain reaction in the case group when compared to 15% in the controls. Also, 30% of the cases were found to be positive with culture compared to none in controls. CONCLUSION A higher frequency of detection of H. pylori in those patients with positive antral biopsy report was seen. Also, polymerase chain reaction was found to be more sensitive than culture for detection. Thus, we conclude that detection of H. pylori in dental plaque of dyspeptic patients cannot be neglected and might represent a risk factor for recolonization of stomach after systemic eradication therapy.

Abstract
BACKGROUND There is a great deal of studies on the relationship between the existence of Helicobacter pylori (H. pylori) in oral cavity (dental plaque) and in stomach of patients, with conflicting results worldwide. The purpose of this study was to systematically review the existing litreature to assess if the dental plaque could be a source of gastric H. pylori infection and to explore the source of heterogeneity around it. METHODS We searched all the papers published since 2000 on international (Medline, ISI, Embase) databases using standard keywords. Two researchers evaluated the articles with standard critical appraisal form independently and those articles with the quality acquired greater than 70% were included in the study. The combined results were calculated with weighted average and the source of hetrogeneity was tested by meta-regression (random) model. RESULTS Finally, 23 studies were included (1861 patients). The prevalence of co-infection of gastric and dental plaque H. pylori was 49.7% (95% CI 16-83.4%) and the percent of agreement between the dental plaque H. pylori status and the gastric H. pylori was estimated as 82%. Only one study has reported that dental treatment has a preventive effect on the recurrence of gastric H. pylori infection. CONCLUSION Co-infection of gastric H. pylori and dental plaque is reported by half of the studies. However, there is not enough evidence for the efficacy of dental treatment on prevention of recurrent gastric H. pylori infection.

Abstract
OBJECTIVES Since 1999, the public dental health service (PDHS) in the county of Värmland, Sweden, has two co-existing patient financial systems, i.e. ways for the patient to pay for dental care services. Alongside the traditional system of fee-for-service payment, i.e. paying afterwards for provided services, a new system of contract care is offered. In this system, dental care is covered by a contractual agreement, for which the patient pays an annual fee and receives care covered by the contract without additional costs. The aim of this article was to study whether patient financial system was associated with oral health-related quality of life (OHRQoL). METHODS A questionnaire was answered by 1324 randomly selected patients, 52% from contract care and 48% from fee-for-service. The questionnaire contained questions about how much one was prepared to pay for dental care, how much one paid for dental care the previous year, OHIP-14 (measured OHRQoL), dental anxiety, humanism of caregiver, SF-36 (measured general health), multidimensional health locus of control, sense of coherence (SOC), self-esteem and demographics. Data on patient financial system, gender and age were obtained from the sampling frame. The material was analysed with a hierarchical block method of multiple regression analysis. RESULTS When controlling for all other variables, patient financial system was one of the strongest associations with OHRQoL: patients in fee-for-service had worse OHRQoL than those in contract care. OHRQoL was also associated with general health, SOC and to some extent also with psychological and economic factors. Of the social variables, only being foreign born was significant: it was associated with worse OHRQoL. CONCLUSIONS Patient financial system was associated with OHRQoL when controlling for confounding factors: patients in contract care had better OHRQoL than those in fee-for-service care.

Abstract
BACKGROUND Helicobacter pylori infection is associated with numerous gastroduodenal diseases. The oral cavity could be a potential extragastric reservoir for H. pylori, and oral H. pylori might cause gastric reinfection after the eradication therapy. The aim of the study was to evaluate the presence of H. pylori in oral cavity of patients with gastric H. pylori infection and to examine the effectiveness of the eradication therapy against H. pylori in stomach and in the oral cavity. METHODS Fifty-six patients with chronic periodontitis and gastric H. pylori were enrolled in the study. Gastric H. pylori infection was determined using (13) C-urea breath test before and 3 months after eradication therapy. The presence of the oral H. pylori was assessed using polymerase chain reaction before and 3 months after eradication therapy. The 1-week eradication therapy consisted of amoxycilin 1 g, clarithromycin 500 mg, and proton pump inhibitor 20 mg twice a day. RESULTS Of 56 subjects with gastric infection, 23 (41.1%) harbored H. pylori in the oral cavity. Eradication rate in stomach was 78.3%, whereas in the oral cavity, H. pylori was not detected from any sample after the eradication therapy. CONCLUSION Almost half of the patients with gastric H. pylori harbored the bacterium in the oral cavity. After the eradication therapy, H. pylori was not detected in the oral cavity, what suggests high effectiveness of the therapy protocol in the oral cavity, or it is possible that oral H. pylori is of a transient character.

Abstract
Splenogastric hygropyrexia syndrome, a common syndome in clinical practice, responds well to the therapy of traditional Chinese medicine (TCM). In view of the complexity of TCM syndrome formation, proceeding from different aspects such as Helicobacter pylori (Hp) infection, expression of inflammatory factors, mucosal protection and change in micro-ecosystem, the authors proposed that Hp infection in gastric mucosa, nuclear factor-kappa B activation, over-expression of heat shock protein 70, and "excessive evil, dyssplenism and confliction between healthy energy and evils" due to disequilibrium between Hp and lactobacillus acidophilus in gastric mucosa and coated tongue may be the important links in the formation of Hp related gastrosis with splenogastric hygropyrexia syndrome.

Abstract
There is documented evidence of significant associations between cancer of the lung, kidney, pancreas, hematological and oral cancers and periodontal diseases of the supporting structures of the teeth. Enhanced lipid peroxidation, raised levels of TBARS and the oxidative stress marker malondealdehyde have been detected in breast cancer with reduced antioxidant capacity, also characteristic of periodontal diseases. Antioxidants could overcome this deficit and attenuate disease progression by down regulating glutathione detoxification/redox buffering system and inhibiting key transcription factors. Periodontal disease may be a critical marker of a susceptible immune system, or initiate cancer risk with a pro-oxidant inflammatory profile.

Abstract
Helicobacter pylori is a Gram-negative microaerophilic bacterium that has colonized the human gastric mucosa. This infection is very common and affects more than half of the human population. The prevalence is however unbalanced between rural developing areas (more than 80%) and urban developed areas (less than 40%). H. pylori is responsible for several pathologies, such as gastritis, peptic ulcer and gastric cancer but its transmission pathway is still not clear. The risk factors for H. pylori infection include poor social and economic development; poor hygienic practices; absence of hygienic drinking water; and unsanitary prepared food. There is evidence supporting a gastro-oral, oral-oral and faecal-oral transmission, but no predominant mechanism of transmission has been yet identified. Transmission may occur in a vertical mode (e.g. from parents to child) or in a horizontal mode (across individuals or from environmental contamination). In either case, the involvement of water and food cannot be excluded as vehicles or sources of infection. Indirect evidence of presence of H. pylori in water and food, namely the detection of its DNA and survival studies after artificial contamination of food and water has been described. This paper reviews data both favourable and against the role of water and food in the transmission of H. pylori, exploring their role as a potential transmission vehicle for person-to-person and food-chain transmission. The likelihood of the transmission pathway in developing rural and developed urban areas appears to be different. In developed areas, person-to-person transmission within families appears to be dominant, while in the rural developing areas the transmission pathway appears to be more complex. In this later case, the transmission by contaminated food, water, or via intensive contact between infants and non-parental caretakers may have a greater influence than within-family transmission.

Abstract
BACKGROUND Data on the role of dental plaque in the transmission of Helicobacter pylori have varied. Furthermore, there has been few reports on the relationship between dental plaque control and H. pylori infection of gastric mucosa. The purpose of this study was to elucidate this potential relationship. METHODS The (13)C urea breath test was conducted on 56 subjects who received dental plaque control and 51 subjects who did not. RESULTS The prevalence of H. pylori in the gastric mucosa was 19.64% in patients who received dental plaque control, which was significantly lower than in those without dental plaque control (84.31%). CONCLUSION Long-term professional dental plaque control was associated with less gastric reinfection by H. pylori, suggesting that dental plaque control may help to prevent H. pylori-induced gastric disease or reinfection.

Abstract
BACKGROUND In Mexico, more than 80% of the population is infected with Helicobacter pylori. The frequency of H. pylori detection in the oral cavity is unknown, as its relationship with gastroesophageal pathology. AIM To detect the presence of H. pylori in the oral cavity in Mexican population by PCR and to determine its association with gastroesophageal disease. METHODS Patients were divided into two groups with different clinic conditions from whom gastric biopsy, dental plaque, and saliva samples were taken and analyzed. The first group comprised of hospitalized patients, the majority of whom were diagnosed with gastroesophageal disease, while the second group was selected from a dental clinic (ambulatory population) the majority of whom appeared to be healthy subjects. RESULTS H. pylori was detected in gastric biopsy, dental plaque and saliva samples by PCR using a set of specific primers for the signal sequence of the vacuolating cytotoxin gene; detection of H. pylori in general was higher in gastric biopsy and dental plaque samples than in saliva samples. Detection of H. pylori in the oral cavity is significantly (P = 0.0001) associated with patients presenting gastroesophageal disease, while healthy subjects and those with other non-gastric disease do not present with H. pylori in their oral cavity. CONCLUSIONS H. pylori detection in the oral cavity is associated to gastroesophageal disease. In addition, it is suggested that all patients presenting gastric symptoms and H. pylori detection in the oral cavity would begin bacterial treatment immediately.

Abstract
The oral cavity has been proposed as a reservoir for H. pylori that could be responsible for the refractoriness of gastric infection to triple therapy (antibiotics, antimicrobials, and proton pump inhibitors). The aim of this study was to evaluate the efficiency of combined periodontal and triple therapy vs. triple therapy alone, in gastric H. pylori eradication in persons with H. pylori in the subgingival biofilm. Individuals positive for H. pylori in their gastric and oral samples, as determined by nested PCR, were treated either with periodontal and triple therapy or with triple therapy alone. Our results indicate that 77.3% of those treated with the combined therapy exhibited successful eradication of gastric H. pylori, compared with 47.6% who underwent only triple therapy. Analysis of these data suggests that periodontal treatment in combination with systemic therapy could be a promising approach to increasing the therapy's efficacy and decreasing the risk of infection recurrence.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common human infections worldwide. It is associated with the development of a number of important upper gastrointestinal (GI) diseases such as chronic gastritis, peptic ulcer and gastric malignancy. At present, there is evidence that H. pylori infection probably plays a critical role in the development of some extragastric diseases. However, there is still controversy over such association. In this article, we will give an overview of the recent advances in understanding the association of H. pylori infection with extragastric diseases.

Abstract
BACKGROUND Betel chewing has been shown to predispose to periodontal disease and oral cancer. Studies show that people with gum disease are more likely to test positive for Helicobacter pylori (H. pylori). It is not known if the lesions produced by betel quid and the resulting, chemical changes predispose to colonization by H. pylori. Further the role of this organism in oral cancer is not known. Our objective was to determine the presence of H. pylori in oral lesions of thirty oral cancer patients and to determine the presence of IgG antibodies to H. pylori in oral cancer patients who are betel chewers and non betel chewers, healthy betel chewers and healthy non-betel chewers and to compare the presence of H. pylori in these four groups. This case control study was conducted at the Cancer Institute Maharagama and the Department of Microbiology, Faculty of Medical Sciences, University of Sri Jayewardenepura. METHODS One hundred and seventy three subjects, of whom fifty three were patients presenting with oral cancer to the Cancer Institute Maharagama, sixty healthy betel chewers and sixty healthy non-betel chewers from the Religious and Welfare Service Centre Maharagama were tested for H. pylori by serology. Thirty oral biopsies from oral cancer patients were cultured under microaerophilic condition to isolate H. pylori. The statistic used was Chi-square test. RESULTS Of the fifty-three oral cancer patients, forty-four were betel chewers. Among the 53 oral cancer patients examined, ten of forty-four (10/44 = 22.7%) patients who are betel chewers and four of nine (4/9 = 44.4%) patients who are non-betel chewers were detected positive for IgG antibody against H. pylori. In the healthy group (betel chewers and non betel chewers) ten (16.7%) of the healthy betel chewers tested positive for H. pylori by serology. None of the healthy non-betel chewers tested positive for H. pyloriFourteen [26.4%] of oral cancer patients tested positive for H. pylori by serology, of which two were also culture positive (Only thirty samples were cultured). The presence of H. pylori in betel chewers (with or without cancer) compared to non-betel chewers was statistically significant. (Chi-square test p < 0.05) The use of tobacco and areca nut in betel chewers was significant with the presence of H. pylori (p < 0.05). CONCLUSION There is a significant higher proportion of H. pylori in betel chewers compared to non-betel chewers but not between oral cancer patients compared to patients without oral cancer. Hence Betel chewing may predispose to colonisation with H. pylori in the digestive tract through swallowing the quid or during betel chewing.

Abstract
INTRODUCTION Helicobacter pylori infection is very prevalent in Brazil, infecting almost 65% of the population. The aim of this study was to evaluate the presence of this bacterium in the oral cavity of patients with functional dyspepsia (epigastric pain syndrome), establish the main sites of infection in the mouth, and assess the frequency of cagA and vacA genotypes of oral H. pylori. METHODS All 43 outpatients with epigastric pain syndrome, who entered the study, were submitted to upper gastrointestinal endoscopy to rule out organic diseases. Helicobacter pylori infection in the stomach was confirmed by a rapid urease test and urea breath tests. Samples of saliva, the tongue dorsum and supragingival dental plaque were collected from the oral cavity of each subject and subgingival dental plaque samples were collected from the patients with periodontitis; H. pylori infection was verified by polymerase chain reaction using primers that amplify the DNA sequence of a species-specific antigen present in all H. pylori strains; primers that amplify a region of urease gene, and primers for cagA and vacA (m1, m2, s1a, s1b, s2) genotyping. RESULTS Thirty patients harbored H. pylori in the stomach, but it was not possible to detect H. pylori in any oral samples using P1/P2 and Urease A/B. The genotype cagA was also negative in all samples and vacA genotype could not be characterized (s-m-). CONCLUSION The oral cavity may not be a reservoir for H. pylori in patients with epigastric pain syndrome, the bacterium being detected exclusively in the stomach.

Abstract
This study compared the frequency of Helicobacter pylori, Enterococcus faecalis, and Pseudomonas aeruginosa in the subgingival microbiota of HIV-seropositive and HIV-seronegative subjects with periodontitis or clinically healthy periodontal tissues. Fifty-four subjects were distributed into two HIV-seropositive groups (chronic periodontitis [HCP = 13] and periodontal health [HH = 10]) and two HIV-seronegative groups (chronic periodontitis [CP = 17] and periodontal health [H = 14]). The detection of bacterial species was carried out by polymerase chain reaction (PCR). CP patients showed significantly more periodontal destruction, inflammation, and supragingival plaque than HCP patients (P < 0.05). All species were detected at a higher prevalence in CP and HCP than H individuals (P < 0.01). In the HIV groups, H. pylori was significantly more prevalent in periodontitis compared to healthy patients (P < 0.01). A higher frequency of E. faecalis and P. aeruginosa was observed in the subgingival biofilm of HH than H subjects (P < 0.01). Moreover, E. faecalis was detected significantly more often in HIV-seropositive compared to HIV-seronegative patients, regardless of periodontal status (P < 0.01). These data indicate that H. pylori is frequently detected in the subgingival microbiota of periodontitis subjects. In contrast, HIV-seropositive patients with either periodontitis or periodontal health present a high prevalence of E. faecalis.
