Zhang Z, Yi X, Ding Y. Association between Helicobacter pylori infection and oral lichen planus: A meta-analysis. Heliyon 2024; 10:e32644. [PMID: 38975084 PMCID: PMC11226839 DOI: 10.1016/j.heliyon.2024.e32644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 06/06/2024] [Accepted: 06/06/2024] [Indexed: 07/09/2024] Open
Abstract
Background Oral lichen planus (OLP) is a T cell-mediated autoimmune disease that affects the oral mucosa. Although Helicobacter pylori has been documented in subgingival and supragingival plaques and saliva, little is currently known about the relationship between Helicobacter pylori and OLP, warranting further research. Methods PubMed, Embase, Chinese National Knowledge Infrastructure (CNKI), and Web of Science databases were thoroughly searched for relevant articles published from inception until May 23, 2023. Results Due to high heterogeneity among the included studies (Tau2 = 2.16;χ 2 = 40.33, df = 6; I 2 = 85 %), we employed a random-effects model (REM). The forest plot revealed a significant correlation between H. pylori infection and OLP, with an odds ratio (OR) of 4.69 (95 % CI: 1.36 to 16.19; P < 0.01). Sensitivity analysis showed that the pooled ORs ranged from 3.69 (95 % CI: 1.01 to 13.44; P = 0.05) to 6.77 (95 % CI: 2.65-17.30; P < 0.001), and no single study significantly influenced the results when removed individually. Additionally, subgroup analysis was conducted to investigate the relationship between H. pylori infection and OLP and explore the sources of heterogeneity. Finally, Begg's test (P = 0.24) and Egger's test (P = 0.35) were performed on the included studies, and the results indicated no significant publication bias. Conclusion Our meta-analysis suggests a close association between H. pylori infection and OLP. Nevertheless, further research is warranted to validate these results in the future.

[PMID: 39064467 PMCID: PMC11278918 DOI: 10.3390/medicina60071038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 06/18/2024] [Accepted: 06/19/2024] [Indexed: 07/28/2024]
Abstract
Background and Objectives: An oral lichen planus (OLP) chronic lesion refers to a group of oral potentially malignant disorders (OPMDs) that still lack a proper understanding from the point of view of relevant biomarkers for diagnostics and prognosis. The aim of the study was to assess the salivary histamine levels in patients with oral lichen planus lesions. Materials and Methods: The study included a group of 76 patients with oral lichen planus. General diseases and medication taken, smoking habits, severity of pain assessed using a visual analogue scale (VAS), oral hygiene status, and duration of OLP were evaluated. ELISA diagnostics for histamines in saliva levels were assessed. Results: The histamine levels in the OLP group were higher (0.468) in comparison with the control group (0.056), without a statistically significant value p = 0.090 (Mann-Whitney U Test). The median age of 76 OLP patients was 63 years (min 22.0-max. 81), with the biological sex being 80.3% females and 15 19.7% males. The average duration of OLP lesion presence was 29.4 months (SD 37.1) and the median value was 14.5 months. The median of the VAS was 3.0. OLP assessment in accordance with the Malhotra methodology showed the highest frequency-30.3% for only two of the point areas involved and 17.1% for three points. Clinical assessment of the different OLP grades, severity, and oral site involvement and the VAS in correlation with histamine salivary levels showed a lack of statistical significance in the investigated population. Conclusions: Undertaking further research could provide further possibilities for searching for general factors in OLP development.

Abstract
Background Microbiomes are essential components of the human body, and their populations are substantial. Under normal circumstances, microbiomes coexist harmoniously with the human body, but disturbances in this equilibrium can lead to various diseases. The oral microbiome is involved in the occurrence and development of many oral and gastrointestinal diseases. This review focuses on the relationship between oral microbiomes and oral and upper gastrointestinal diseases, and therapeutic strategies aiming to provide valuable insights for clinical prevention and treatment. Methods To identify relevant studies, we conducted searches in PubMed, Google Scholar, and Web of Science using keywords such as "oral microbiome," "oral flora, " "gastrointestinal disease, " without any date restrictions. Subsequently, the retrieved publications were subject to a narrative review. Results In this review, we found that oral microbiomes are closely related to oral and gastrointestinal diseases such as periodontitis, dental caries, reflux esophagitis, gastritis, and upper gastrointestinal tumors (mainly the malignant ones). Oral samples like saliva and buccal mucosa are not only easy to collect, but also display superior sample stability compared to gastrointestinal tissues. Consequently, analysis of the oral microbiome could potentially serve as an efficient preliminary screening method for high-risk groups before undergoing endoscopic examination. Besides, treatments based on the oral microbiomes could aid early diagnosis and treatment of these diseases. Conclusions Oral microbiomes are essential to oral and gastrointestinal diseases. Therapies centered on the oral microbiomes could facilitate the early detection and management of these conditions.

[PMID: 38668300 PMCID: PMC11054144 DOI: 10.3390/pathogens13040345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 04/29/2024] Open
Abstract
Molar incisor hypomineralization (MIH) is a congenital disorder of the enamel tissue, characterized by a quantitative deficiency. In childhood, infections such as EBV, HSV-1, HCMV, or H. pylori may occur and cause various diseases. This study aimed to investigate the prevalence of HPV, EBV, HSV-1, HCMV, and H. pylori infections in two groups of children: children with molar incisor hypomineralization (MIH) and a control group, using molecular methods. The study group included 47 children aged between 6-13 years who had been diagnosed with MIH. The control group consisted of 42 children. The study found that, in the MIH group, the prevalence of HPV-16 was 6.38%, HPV-18 was 4.26%, EBV was 31.91%, HSV-1 was 4.26%, HCMV was 4.26%, and H. pylori was 12.77%. There were no significant differences in the prevalence of any of tested pathogens between the study and the control group (p > 0.05). However, the study found a higher prevalence of EBV infection in children who had smallpox/pneumonia by the age of 3 years. Ten children were found to have at least two pathogens present. Moreover, both groups had a high prevalence and activity of EBV. These findings provide new insights into the carriage of pathogens among children with MIH, providing new information for parents, scientists, and healthcare professionals.

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
Helicobacter pylori (H. pylori) has coevolved with its human host for more than 100 000 years. It can safely colonize around the epithelium of gastric glands via their specific microstructures and proteins. Unless patients receive eradication treatment, H. pylori infection is always lifelong. However, few studies have discussed the reasons. This review will focus on the adhesion of H. pylori from the oral cavity to gastric mucosa and summarize the possible binding and translocation characteristics. Adhesion is the first step for persistent colonization after the directional motility, and factors related to adhesion are necessary. Outer membrane proteins, such as the blood group antigen binding adhesin (BabA) and the sialic acid binding adhesin (SabA), play pivotal roles in binding to human mucins and cellular surfaces. And this may offer different perspectives on eradication.

Abstract
Lichen planus is a chronic disease affecting the skin, appendages, and mucous membranes. A cutaneous lichen planus is a rare disease occurring in less than 1% of the general population, while oral illness is up to five times more prevalent; still, both forms equally impair the patient's quality of life. The etiology of lichen planus is not entirely understood. Yet, immune-mediated mechanisms have been recognized since environmental factors such as hepatitis virus infection, mechanical trauma, psychological stress, or microbiome changes can trigger the disease in genetically susceptible individuals. According to current understanding, lichen planus immunopathogenesis is caused by cell-mediated cytotoxicity, particularly cytotoxic T lymphocytes, whose activity is further influenced by Th1 and IL-23/Th-17 axis. However, other immunocytes and inflammatory pathways complement these mechanisms. This paper presents a comprehensive insight into the actual knowledge about lichen planus, with the causal genetic and environmental factors being discussed, the immunopathogenesis described, and the principal effectors of its inflammatory circuits identified.

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.

Abstract
Background Oral lichen planus (OLP) is a multifactorial chronic inflammatory condition with unknown etiology. This condition has been associated with Helicobacter pylori. This study aimed to investigate the relationship between the treatment of H. pylori infection and improvements in OLP lesions. Methods In this cohort study, 42 patients with erosive or ulcerative OLP lesions were evaluated in terms of H. pylori infection using the H. pylori stool antigen (HpSA) test. The patients were divided into three groups. The first group consisted of 12 H. pylori-negative patients. The second group consisted of 21 H. pylori-positive patients receiving antibacterial treatment. The third group included nine H. pylori-positive patients not willing to receive treatment. All the three groups underwent the usual OLP treatment. Patients in the second and third groups were re-evaluated by the HpSA test after two months. The efficacy indexes and visual analog scale were used to evaluate clinical improvements. Results The efficiency index and pain scores were affected by the intervention (P<0.001). The logistic regression analysis showed that the severity index before treatment was significantly effective (OR=0.745 (95% CI: 0.602‒0.923; P=0.007). No statistical significance for factors affecting other variables (P>0.05) was obtained. Conclusion Pain intensity was higher in patients with H. pylori than in those without H. pylori before treatment. Also, in patients with H. pylori, the treatment affects the complete recovery rate.

Abstract
Background and objectives: To compare the efficacy and safety of topical interventions used for recurrent aphthous stomatitis. Materials and Methods: This network meta-analysis was conducted in accordance with the PRISMA statement. We searched four electronic databases, PubMed, Web of Science (WOS), Cochrane Central Register of Controlled Trials and Embase, for randomized controlled trials reporting efficacy and safety data on topical interventions for recurrent aphthous stomatitis. We performed a quality evaluation using a methodology based on the Cochrane Handbook. Two authors independently extracted data on healing effect, size reduction effect, symptom reduction effect, recurrence and safety assessment. Network meta-analysis was then performed using ADDIS and RevMan. Results: A total of 72 trials (5272 subjects) involving 29 topical interventions were included. Honey, lnsulin liposome gel, laser, amlexanox, glycyrrhiza and triamcinolone had better efficacy performance. Probiotics and chlorhexidine helped to prolong ulcer intervals and reduce recurrence. Doxycycline and penicillin had a high risk of adverse events. Hematologic evaluation showed no preference. The rank possibility of size-reducing effect and symptom-reducing effect supported the short-term effect of laser and the long-term effect of probiotics. Conclusions: We recommend the use of laser as a short-term intervention during the exacerbation phase of RAS and probiotics as a long-term intervention during the exacerbation and remission phases of RAS.

Abstract
Simple Summary Oral lichen planus is a disease of the oral mucosa, which frequently affects women aged 40 years or older. Though the T cell-mediated immune response is involved in the development of oral lichen planus, attempts to identify a microorganism that causes the disease have been unsuccessful. Recent studies on the development of oral lichen planus are focusing on the role of the oral microbiome, which includes oral microbiota and their products, and the host environment. The role of the human microbiome in various diseases has been identified and regulating the microbiome is becoming important in personalized medicine. In this review, we summarized current findings on the role of the oral microbiome in the development of oral lichen planus. The homeostasis of the oral microbiome is disrupted in patients, and functional analysis of oral microbiota and oral mucosa implies that pathways involved in defense against bacterial infection and in the inflammatory response are activated in the oral lichen planus-associated oral microbiome. Though the lack of studies to date makes it difficult to conclude, further studies on the oral microbiome associated with the disease will enable a holistic understanding of the role of the oral microbiome in the development of oral lichen planus and developing a personalized therapy for the disease. Abstract Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa with an unknown etiology. The role of oral microbes in the development of OLP has gained researchers’ interest. In this review, we summarized the findings of studies focused on the relationship between OLP and oral microbiome, which includes the composition of oral microbiota, molecules produced by oral microbiota or the host, and the oral environment of the host. According to the studies, the oral microbial community in OLP patients undergoes dysbiosis, and the microbial dysbiosis in OLP patients is more prominent in the buccal mucosa than in the saliva. However, no same microorganisms have been suggested to be associated with OLP in multiple investigations, implying that the functional aspects of the oral microbiota are more important in OLP development than the composition of the oral microbiota. According to studies on host factors that make up the oral environment, signal pathways involved in cellular processes, such as keratinization, inflammation, and T cell responses are triggered in OLP. Studies on the functional aspects of the oral microbiota, as well as interactions between the host and the oral microbiota, are still lacking, and more research is required.

Abstract
Oral aphthosis is a painful inflammatory process of the oral mucosa. Oral aphthous can appear alone or secondary to numerous distinct disease processes. If recurrence occurs frequently, it is called recurrent aphthous stomatitis. The pathophysiology of oral aphthous ulcers remains unclear but various bacteria are part of its microbiology. Three morphological types hold great importance in literature because these types help manage the illness properly. Google Scholar and PubMed databases were used to retrieve the relevant data and information. Different keywords including "Aphthous", "Aphthosis", "Canker sores", "Aphthous stomatitis", "Aphthous ulcer causes", "Aphthous ulcer AND Microbiota" and "Aphthous ulcer AND treatment". The causes for oral aphthous ulcerations are widespread and ranges from localized trauma to rare syndromes, underlying intestinal disease, or even malignant disease processes. A detailed history and thorough examination of systems can assist the physician or dermatologist in defining whether it is related to a systemic disease process or truly idiopathic. Management of oral aphthous ulcers is challenging. For oral aphthous or recurrent aphthous ulcers from an underlying disease, topical medications are preferred due to their minimum side effects. Systemic medications are necessary if the disease progresses. Within the limitation of research and literature provided, it is safe to say that topical corticosteroids are the first line of treatment. Herein, the author discusses the pathophysiology, types, causes, diagnosis, and appropriate treatment ladder of oral aphthous stomatitis as described in the literature.

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.

Abstract
Helicobacter pylori is associated with chronic gastritis, gastric or duodenal ulcers, and gastric cancer. Since the oral cavity is the entry port and the first component of the gastrointestinal system, the oral cavity has been discussed as a potential reservoir of H. pylori. Accordingly, a potential oral-oral transmission route of H. pylori raises the question concerning whether close contact such as kissing or sharing a meal can cause the transmission of H. pylori. Therefore, this topic has been investigated in many studies, applying different techniques for detection of H. pylori from oral samples, i.e. molecular techniques, immunological or biochemical methods and traditional culture techniques. While molecular, immunological or biochemical methods usually yield high detection rates, there is no definitive evidence that H. pylori has ever been isolated from the oral cavity. The specificity of those methods may be limited due to potential cross-reactivity, especially with H. pylori-like microorganisms such as Campylobacter spp. Furthermore, the influence of gastroesophageal reflux has not been investigated so far. This review aims to summarize and critically discuss previous studies investigating the potential colonization of H. pylori in the oral cavity and suggest novel research directions for targeting this critical research question.

Abstract
BACKGROUND Oral lichen planus (OLP), a common clinical oral disease, is associated with an increased risk of malignant transformation. The mechanism underlying the pathogenesis of OLP is unknown. Oral dysbacteriosis is reported to be one of the aetiological factors of OLP. Although Helicobacter pylori infection is associated with various oral diseases, the correlation between H. pylori infection and OLP is unclear. This study aimed to investigate the effect of H. pylori infection on OLP pathogenesis and oral microbiome composition in the Chinese population, which has a high incidence of H. pylori infection. RESULT In this study, saliva samples of 30 patients with OLP (OLP group) and 21 negative controls (NC group) were collected. H. pylori infection was detected using the carbon-13-labeled urea breath test (UBT). The saliva samples were divided into the following four groups based on the H. pylori status: H. pylori-positive OLP (OLP+), H. pylori-positive NC (NC+), H. pylori-negative OLP (OLP-), and H. pylori-negative NC (NC-). Oral microbiome compositions were significantly different between the OLP and NC groups and between the OLP- and OLP+ groups. Compared with those in the OLP- group, those in the OLP+ group had a higher incidence of erosive OLP and higher levels of salivary cytokines. In contrast, the oral microbiome composition and cytokine levels were not significantly different between the NC- and NC+ groups. CONCLUSIONS This is the first report to demonstrate that H. pylori infection is significantly correlated with the pathogenesis of erosive OLP.

Abstract
Oral lichen planus (OLP) is a chronic disease of uncertain etiology, although it is generally considered as an immune-mediated disease that affects the mucous membranes and even the skin and nails. Over the years, this disease was attributed to a variety of causes, including different types of microorganisms. This review analyzes the present state of the art of the disease, from a microbiological point of view, while considering whether or not the possibility of a microbial origin for the disease can be supported. From the evidence presented here, OLP should be considered an immunological disease, as it was initially proposed, as opposed to an illness of microbiological origin. The different microorganisms so far described as putative disease-causing agents do not fulfill Koch’s postulates; they are, actually, not the cause, but a result of the disease that provides the right circumstances for microbial colonization. This means that, at this stage, and unless new data becomes available, no microorganism can be envisaged as the causative agent of lichen planus.

Abstract
Saliva is a highly versatile biological fluid that is easy to gather in a non-invasive manner—and the results of its analysis complement clinical and histopathological findings in the diagnosis of multiple diseases. The objective of this review was to offer an update on the contribution of salivary biomarkers to the diagnosis and prognosis of diseases of the oral cavity, including oral lichen planus, periodontitis, Sjögren’s syndrome, oral leukoplakia, peri-implantitis, and medication-related osteonecrosis of the jaw. Salivary biomarkers such as interleukins, growth factors, enzymes, and other biomolecules have proven useful in the diagnosis and follow-up of these diseases, facilitating the early evaluation of malignization risk and the monitoring of disease progression and response to treatment. However, further studies are required to identify new biomarkers and verify their reported role in the diagnosis and/or prognosis of oral diseases.

Abstract
OBJECTIVE We investigated the relationship amongst the oral mucosal bacterial community, clinical severity and inflammatory markers in the two most common immune-mediated oral mucosal diseases, namely recurrent aphthous stomatitis (RAS) and oral lichen planus (LP). METHODS Patients with RAS (n = 15) and LP (n = 18) and healthy controls (n = 13) were recruited using criteria to reduce the effect of factors that influence the microbiota structure independently of oral mucosal disease. Clinical severity was quantified using validated scoring methods. DNA was extracted from oral mucosal swabs for 16S rRNA gene high-throughput sequencing. Salivary cytokines were measured using cytometric bead assays. Correlation studies were conducted amongst microbial diversity, clinical scores and cytokine concentrations. RESULTS We observed a significant reduction of bacterial diversity in LP and RAS patients compared to controls (p = .021 and .044, respectively). Reduced bacterial diversity in LP and RAS correlated with increased clinical scores of the two conditions (⍴ = -0.551 to -0.714). A negative correlation was observed between microbial diversity and salivary interferon-γ, interleukin-17A and interleukin-1β (⍴ = -0.325 to -0.449). CONCLUSIONS This study reports reduced oral microbial diversity in the context of increased mucosal inflammation and supports the role for microbial diversity as a marker or contributor to oral mucosal inflammatory disease activity and development.

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.

Abstract
OBJECTIVE To assess any potential association between Helicobacter pylori and oral squamous cell carcinoma/oral potentially malignant disorders. MATERIALS AND METHODS Data mining was done using PubMed, Cochrane Library, and SCOPUS databases. The search included articles published up to May 2019. Newcastle-Ottawa scale was used to score the quality of the included articles. Data including the type of study, the sample population, the type of oral lesion, and the resulting statistical data were extracted. RESULTS Out of 131 screened articles, only 15 articles fulfilled the eligibility criteria. Among the 15 studies, 9 focused on oral squamous cell carcinoma and 6 focused on oral potentially malignant disorders. Eight out of the 9 oral squamous cell carcinoma studies were included in the meta-analysis. Forest plot was generated using the odds ratio and confidence intervals calculated for each of the included studies. Due to the lack of sufficient studies, the meta-analysis was not performed for oral potentially malignant disorders. CONCLUSION Due to the contradictory results of the included studies, it was not possible to make any conclusive statement on the potential association of H. pylori with oral squamous cell carcinoma. The variations in the methodology, especially the differences in the sensitivity/specificity of the diagnostic modalities could be the cause for differential results. CLINICAL RELEVANCE Although the association of H. pylori with oral squamous cell carcinoma could not be confirmed, it is vital to reduce the excess oral microbial load, especially in patients exhibiting oral mucosal changes with no history of associated risk factors.

Chen M, Fang Y, Cheng L, Wu H. Helicobacter pylori is associated with poor prognosis of laryngeal precancerous lesion. Auris Nasus Larynx 2019; 47:268-275. [PMID: 31443928 DOI: 10.1016/j.anl.2019.08.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Revised: 07/28/2019] [Accepted: 08/08/2019] [Indexed: 12/24/2022]
Abstract
OBJECTIVES Previous evidence suggested Helicobacter pylori (H. pylori) promoted tumorigenesis by inducing inflammation in gastric premalignant disease. Whether this organism affected the development of head and neck precancerous lesion remains unknown. We performed this study to assess the prognostic impact of H. pylori infection on patients with laryngeal precancerous lesion. METHODS In this prospective study, 41 enrolled patients with laryngeal precancerous lesion were arranged into H. pylori-positive group (n=16) and H. pylori-negative group (n=25). Two poor outcomes were recurrence and malignant transformation. Prognostic impact of H. pylori infection was analyzed using the Univariate Cox proportional hazard model and Cochran-Mantel-Haenszel test. We also analyzed the prognostic value of systemic inflammation-based markers. RESULTS During a median follow-up of 32.9 months, recurrence developed in 8 patients in the H. pylori positive group and 5 patients in the H. pylori negative group (50.0% vs. 20.0%, P=0.026, Log-rank test). Malignant transformation developed in 4 patients in the H. pylori positive group and no patients in the H. pylori negative group (25.0% vs. 0.0%, P=0.005, Log-rank test). H. pylori positive group had a significant higher malignant transformation rate after stratifying on the observed covariates. There was no significant difference of recurrence rate in two groups stratified with laryngopharyngeal reflux, size of lesion, and pathological type (Cochran-Mantel-Haenszel test). The basal levels of lymphocyte counts and neutrophils to lymphocytes ratio were significantly different in patients with H. pylori infection. Moreover, the receiver operating characteristic curve analysis revealed a predictive value of lymphocyte counts and neutrophils to lymphocytes ratio for poor outcomes (areas under the curve, 0.658 and 0.651, respectively). CONCLUSION The data demonstrate a malignant transformation-relevant role of H. pylori in laryngeal precancerous lesion. H. pylori infection combined with laryngopharyngeal reflux, size of lesion, and pathological type might relate to recurrence of laryngeal precancerous lesion. And changes of lymphocyte counts and neutrophils to lymphocytes ratio associated with H. pylori infection might deserve as predictive indicators for poor prognosis of laryngeal precancerous lesion.

The Effectiveness of Laser-Assisted Surgical Excision of Leukoplakias and Hyperkeratosis of Oral Mucosa: A Case Series in A Group of Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16020210. [PMID: 30642122 PMCID: PMC6352160 DOI: 10.3390/ijerph16020210] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Revised: 12/26/2018] [Accepted: 01/09/2019] [Indexed: 01/19/2023]
Abstract
Introduction: In the different branches of dentistry, the use of laser to solve different clinical situations is increasing due to numerous advantages that have been studied in literature since the 70s. Leucoplakia and hyperkeratosis can benefit from laser-assisted treatment. In most cases biopsy sampling, histological examination and, if no malignant cells are present, the follow-up is needed. However, even if the lesion is free of dysplasia patients often ask to eliminate these white spots that are always a cause of concern. Aim: From these numerous requests comes the idea of setting up a laser-assisted protocol as less invasive as possible to be offered to patients. The aim of the study is to find a laser-assisted protocol for the surgical excision of leucoplakia and hyperkeratosis that can both improve the clinical aspect of the lesion and be sustainable for patients. The null hypothesis has been identified in the following statement: the treatment is effective and efficient at the same time; where effectiveness was tested with the following criteria: size of the lesion, tactile perception, discomfort, pain; and efficiency with the following criteria: pain and discomfort perceived during the treatment. Materials and methods: To collect all data, a specially designed medical record was used. The diode laser was used with a pulsed mode and the maximum power corresponds to 1.8 W. No anaesthesia was used. Before laser-assisted treatment, the fibre was activated and was used with a contact overflowing. Results: Our results show a decrease in the size of the lesion statistically significant. No pain was referred during treatment, except for a slight burning sensation. Conclusion: In conclusion we can state that the treatment is both efficient and effective.

Abstract
Oral carcinogenesis often leads to the alteration of the microbiota at the site of the tumor, but data are scarce regarding the microbial communities of oral potentially malignant disorders (OPMDs). Punch biopsies were taken from healthy and non-healthy mucosa of OPMD patients to analyze the microbiome using metagenome sequencing. In healthy oral mucosa biopsies the bacterial phyla Firmicutes, Fusobacteria, Proteobacteria, Actinobacteria and Bacteroidetes were detected by Ion Torrent sequencing. The same phyla as well as the phyla Fibrobacteres and Spirochaetes were present in the OPMD biopsies. On the species level, there were 10 bacterial species unique to the healthy tissue and 35 species unique to the OPMD lesions whereas eight species were detected in both samples. We observed that the relative abundance of Streptococcus mitis decreased in the OPMD lesions compared to the uninvolved tissue. In contrast, the relative abundance of Fusobacterium nucleatum, implicated in carcinogenesis, was elevated in OPMD. We detected markedly increased bacterial diversity in the OPMD lesions compared to the healthy oral mucosa. The ratio of S. mitis and F. nucleatum are characteristically altered in the OPMD lesions compared to the healthy mucosa.

Abstract
BACKGROUND Several studies have indicated the larynx as possible Helicobacter pylori (H. pylori) reservoirs. This study explored the association between H. pylori and vocal fold leukoplakia. METHODS The case-control study involved 51 patients with vocal fold leukoplakia and 35 control patients with vocal polyps. Helicobacter pylori was detected in tissues by the rapid urease test, nested polymerase chain reaction (PCR), and single-step PCR. The H. pylori-specific immunoglobulin antibodies were detected in plasma by enzyme-linked immunosorbent assay (ELISA). RESULTS Helicobacter pylori-positive rate of vocal fold leukoplakia and vocal polyps was 23.5% versus 11.4% (P = .157), 37.2% versus 14.3% (P = .020), 27.5% versus 8.6% (P = .031), and 70.6% versus 68.6% (P = .841) detected by rapid urease test, nested PCR, single-step PCR, and ELISA, respectively. Regression analysis indicated that H. pylori infection (P = .044) was the independent risk factor for vocal fold leukoplakia. CONCLUSION Helicobacter pylori infection exists in the larynx and may be associated with vocal fold leukoplakia.

Abstract
BACKGROUND Helicobacter pylori has changed radically gastroenterologic world, offering a new concept in patients' management. Over time, more medical data gave rise to diverse distant, extragastric manifestations and interactions of the "new" discovered bacterium. Special interest appeared within the field of neurodegenerative diseases and particularly Alzheimer's disease, as the latter and Helicobacter pylori infection are associated with a large public health burden and Alzheimer's disease ranks as the leading cause of disability. However, the relationship between Helicobacter pylori infection and Alzheimer's disease remains uncertain. METHODS We performed a narrative review regarding a possible connection between Helicobacter pylori and Alzheimer's disease. All accessible relevant (pre)clinical studies written in English were included. Both affected pathologies were briefly analyzed, and relevant studies are discussed, trying to focus on the possible pathogenetic role of this bacterium in Alzheimer's disease. RESULTS Data stemming from both epidemiologic studies and animal experiments seem to be rather encouraging, tending to confirm the hypothesis that Helicobacter pylori infection might influence the course of Alzheimer's disease pleiotropically. Possible main mechanisms may include the bacterium's access to the brain via the oral-nasal-olfactory pathway or by circulating monocytes (infected with Helicobacter pylori due to defective autophagy) through disrupted blood-brain barrier, thereby possibly triggering neurodegeneration. CONCLUSIONS Current data suggest that Helicobacter pylori infection might influence the pathophysiology of Alzheimer's disease. However, further large-scale randomized controlled trials are mandatory to clarify a possible favorable effect of Helicobacter pylori eradication on Alzheimer's disease pathophysiology, before the recommendation of short-term and cost-effective therapeutic regimens against Helicobacter pylori-related Alzheimer's disease.

Abstract
BACKGROUND A possible relationship between oral lichen planus (OLP) and thyroid disease has received attention in recent years. OBJECTIVE This study aimed to evaluate the correlation between OLP and thyroid diseases in Chinese ethnic patients. METHODS 192 OLP patients, 123 patients with oral lichenoid lesions (OLLs), and 162 controls were recruited in this case-control study. All participants received screening for thyroid function and underwent ultrasound. Sex and age of the patients in the three groups were matched. The prevalence of thyroid diseases in the subjects was analyzed. Using logistic regression, the odds ratio (OR) with 95% confidence intervals was appraised for associations between OLP, OLL, and different types of thyroid diseases [Hashimoto's thyroiditis (HT), hypothyroidism, and thyroid nodule]. RESULTS The prevalence of thyroid diseases in the OLP group (72.4%) and OLL group (68.3%) was higher than the control group (49.4%) with statistical significance. The OR of HT was 3.16 (1.87-5.33) for OLP, 2.09 (1.18-3.70) for OLL, while the OR of thyroid nodule was 2.31 (1.30-4.09) for OLP. CONCLUSION Our study suggested a close relationship between OLP/OLL and HT and thyroid nodule in a Chinese population. The possible mechanism behind this association warrants further investigation.

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
Oral potentially malignant disorders (OPMD) develop in a complex tissue microenvironment where they grow sustainably, acquiring oral squamous cell carcinoma (OSCC) characteristics. The malignant tumor depends on interactions with the surrounding microenvironment to achieve loco-regional invasion and distant metastases. Unlike abnormal cells, the multiple cell types in the tissue microenvironment are relatively stable at the genomic level and, thus, become therapeutic targets with lower risk of resistance, decreasing the risk of OPMD acquiring cancer characteristics and carcinoma recurrence. However, deciding how to disrupt the OPMD and OSCC microenvironments is itself a daunting challenge, since their microenvironments present opposite capacities, resulting in diverse consequences. Furthermore, recent studies revealed that tumor-associated immune cells also participate in the process of differentiation from OPMD to OSCC, suggesting that reeducating stromal cells may be a new strategy to prevent OPMD from acquiring OSCC characteristics and to treat OSCC. In this review, we discuss the characteristics of the microenvironment of OPMD and OSCC as well as new therapeutic strategies.

Abstract
The role of bacterial and viral carcinogenesis in the oral cavity is increasingly of interest, as a means to provide more methods of cancer prevention. There may be relationships between bacteria and multiple strains of viruses in the progression of malignancy. Cancer cause is closely related to the type of carcinogen, as well as the synergistic or additive actions of combined risk factors, the susceptibility of the host, and duration of interaction between host and exposure to risk factor. Much research is underway to further define the role of microbial and bacterial agents in the progression of malignancy.
