Liu S, Wang S, Zhang N, Li P. The oral microbiome and oral and upper gastrointestinal diseases. J Oral Microbiol 2024; 16:2355823. [PMID: 38835339 PMCID: PMC11149586 DOI: 10.1080/20002297.2024.2355823] [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: 01/16/2024] [Accepted: 05/10/2024] [Indexed: 06/06/2024] Open
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.

Patini R, Cordaro M, Marchesini D, Scilla F, Gioco G, Rupe C, D'Agostino MA, Lajolo C. Is Systemic Immunosuppression a Risk Factor for Oral Cancer? A Systematic Review and Meta-Analysis. Cancers (Basel) 2023; 15:3077. [PMID: 37370688 DOI: 10.3390/cancers15123077] [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: 04/30/2023] [Revised: 05/30/2023] [Accepted: 06/01/2023] [Indexed: 06/29/2023] Open
Abstract
Even if the relationship between immunosuppression and increased incidence of systemic cancers is well known, there is less awareness about the risk of developing oral cancer in immunosuppressed patients. The aim of this review was to evaluate the association between immunosuppression and the development of oral cancer. Two authors independently and, in duplicate, conducted a systematic literature review of international journals and electronic databases (MEDLINE via OVID, Scopus, and Web of Science) from their inception to 28 April 2023. The assessment of risk of bias and overall quality of evidence was performed using the Newcastle-Ottawa Scale and GRADE system. A total of 2843 articles was identified, of which 44 met the inclusion criteria and were included in either the qualitative or quantitative analysis. The methodological quality of the included studies was generally high or moderate. The quantitative analysis of the studies revealed that immunosuppression should be considered a risk factor for the development of oral cancer, with a percentage of increased risk ranging from 0.2% to 1% (95% CI: 0.2% to 1.4%). In conclusion, the results suggest that a constant and accurate follow-up should be reserved for all immunosuppressed patients as a crucial strategy to intercept lesions that have an increased potential to evolve into oral cancer.

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.

Abstract
Introduction This study consisted in the comparison of the prevalence of Helicobacter pylori (H. pylori) present in the stomach and in saliva of a sample of Portuguese adolescents and the assessment of the association between H. pylori infection with socio-demographic variables and prevalence of dental caries. Materials and Methods A cross-sectional study was designed including a sample of 447 adolescents aged 12 to 19 years old, attending a public school in Sátão, Portugal. A questionnaire about socio-demographic variables and oral health behaviors was applied. Gastric H. pylori infection was determined using the urease breath test (UBT). Saliva collection was obtained and DNA was extracted by Polymerase Chain Reaction (PCR) in order to detect the presence of oral H. pylori. Results The prevalence of gastric H. pylori detected by UBT was 35.9%. Within the adolescents with a gastric UBT positive, only 1.9% were positive for oral H. pylori. The presence of gastric H. pylori was found to be associated with age (>15years, Odds ratio (OR)=1.64,95%CI=1.08-2.52), residence area (urban,OR=1.48,95%CI=1.03-2.29) and parents´ professional situation (unemployed,OR=1.22,95%CI=1.02-1.23). Among those with detected dental caries during the intra-oral observation, 37.4% were positive for gastric H. pylori and 40.2% negative for the same bacterial strain (p=0.3). Conclusions The oral cavity cannot be considered a reservoir for infection of H. pylori. Gastric H. pylori infection was found to be associated with socio-demographic variables such as age, residence area and socioeconomic status.

Abstract
BACKGROUND Few studies have focused on the relationship between Helicobacter pylori (H. pylori) infection and oral diseases. In this study, we explored the correlation between H. pylori infection and oral squamous cell carcinoma (OSCC). METHODS A total of 68 patients with OSCC and 104 age- and sex- matched healthy control subjects were retrospectively enrolled in this study. The H. pylori immunoglobin (Ig) G antibodies in serum were detected by enzyme-linked immunosorbent assay (ELISA) method to assess the status of H. pylori infection of our study sample. Polymerase chain reaction (PCR) was also employed using H. pylori genus-specific 16S rRNA primers in fasting blood, and OSCC specimens were analyzed by histochemical stain of each enrolled subject. The strength of correlation between H. pylori and the development of OSCC was estimated by Spearman's correlation coefficient. RESULTS According to the three methods for detecting prevalence of H. pylori infection in the patients with OSCC, it was statistically lower than that in the healthy controls (35.3% vs. 54.8%, P = 0.012). An inverse correlation was observed between H. pylori infection and OSCC development (Spearman's correlation coefficient = -0.191, P = 0.012). In stratification analysis, we also found a statistical association between H. pylori infection and OSCC in the subpopulation with age ≥ 60 years (P = 0.037). CONCLUSION Our findings suggested that H. pylori infection may be negatively related to OSCC. A reverse association of H. pylori infection with OSCC risk in the subpopulation with age ≥ 60 years was also found.

Abstract
Helicobacter pylori (H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions.
