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

Abstract
OBJECTIVE This study was presented to reveal the most distinct microbial prevalence in recurrent aphthous stomatitis (RAS) lesions compared to healthy controls. DESIGN The case-control studies were selected in electronic databases until Nov 2022 with key search terms, and the eligible publications were screened and analyzed by independent authors. RESULTS A total of 14 studies were identified, which included 531 cases of active states of RAS (AS-RAS), 92 cases of passive states of RAS (PS-RAS) and 372 healthy controls. The most sample pattern was the mucosa swab performed in 8 of 14 studies, biopsies in 3 studies, followed by micro-brush, and saliva. A variety of bacteria in higher or lower abundance were observed in RAS lesions. CONCLUSIONS The etiopathogenesis of RAS may not be ascribed to a single pathogen. A possible explanation is that microbial interactions modify immune response or destroy the epithelial integrity, thus contributing to the development of the condition.

Abstract
Abstract
Recurrent aphthous ulcers are common painful mucosal conditions affecting the oral cavity. Despite their high prevalence and knowledge of many etiological factors, the exact mechanism of disease is still not fully understood. There are three different clinical forms of recurrent aphthous stomatitis and the therapy differs depending on it.
The aim of this article is to provide an overview of current knowledge about the possible causes and treatment of recurrent aphthous stomatitis. We discuss its pathogenesis which is currently the least explained in the literature. This review offers scientists and clinicians useful information about clinical presentation, diagnosis, predisposing aetiological factors and recent trends in the management of recurrent aphthous stomatitis.

Abstract
OBJECTIVES To evaluate the role of Helicobacter pylori and other risk factors in recurrent aphthous stomatitis (RAS). METHODS Patients with functional dyspepsia responded to questionnaires regarding demographic and clinical data, anxiety and depression, and a specific RAS questionnaire. They underwent upper digestive endoscopy and H. pylori evaluation. RESULTS 476 patients were included and of the 372 evaluated for H. pylori, 65.6% were H. pylori-positive. RAS was reported by 32.6% (155/476). In the bivariate analysis of the 372 patients evaluated for gastric H. pylori status, positive subjects had a lower RAS prevalence (29.9%; 73/244) than H. pylori-negative (41.4%; 53/128) (p = .026). Smoking (p = .005) and older age (p = .034) were also associated with a lower prevalence, while female gender (p = .032) and lower income (p = .046) presented higher RAS prevalence. In the multivariate analysis, H. pylori infection (p = .017), smoking (p = .001), and older age (p = .013) were protective factors, while lower income (p = .030) and anxiety (p = .042) were risk factors. In the multivariate analysis of all patients, female gender, lower income, and more schooling years were risk factors. CONCLUSIONS An unexpected lower prevalence of RAS was found in H. pylori-positive patients. Smoking, sex, age, income, education, and anxiety were associated with RAS.

Abstract
Background Recurrent aphthous stomatitis (RAS) is a recurrent painful ulcerative disorder that commonly affects the oral mucosa. Local and systemic factors such as trauma, food sensitivity, nutritional deficiencies, systemic conditions, immunological disorders and genetic polymorphisms are associated with the development of the disease. Helicobacter pylori (H. pylori) is a gram-negative, microaerophile bacteria, that colonizes the gastric mucosa and it was previously suggested to be involved in RAS development. In the present paper we reviewed all previous studies that investigated the association between RAS and H. pylori. Material and Methods A search in Pubmed (MEDLINE) databases was made of articles published up until July 2015 using the following keywords: Helicobacter Pylori or H. pylori and RAS or Recurrent aphthous stomatitis. Results Fifteen experimental studies that addressed the relationship between infection with H. pylori and the presence of RAS and three reviews, including a systematic review and a meta-analysis were included in this review. The studies reviewed used different methods to assess this relationship, including PCR, nested PCR, culture, ELISA and urea breath test. A large variation in the number of patients included in each study, as well as inclusion criteria and laboratorial methods was observed. H. pylori can be detected in the oral mucosa or ulcerated lesion of some patients with RAS. The quality of the all studies included in this review was assessed using levels of evidence based on the University of Oxford’s Center for Evidence Based Medicine Criteria. Conclusions Although the eradication of the infection may affect the clinical course of the oral lesions by undetermined mechanisms, RAS ulcers are not associated with the presence of the bacteria in the oral cavity and there is no evidence that H. pylori infection drives RAS development. Key words:Campylobacter, elisa, h. pylori, Helicobacter Pylori, RAS, recurrent aphthous stomatitis, PCR.

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
Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease affecting the oral mucosa. RAS occurs mostly in healthy individuals and has an atypical clinical presentation in immunocompromised individuals. The etiology of RAS is still unknown, but several local, systemic, immunologic, genetic, allergic, nutritional, and microbial factors, as well as immunosuppressive drugs, have been proposed as causative agents. Clinical management of RAS using topical and systemic therapies is based on severity of symptoms and the frequency, size, and number of lesions. The goals of therapy are to decrease pain and ulcer size, promote healing, and decrease the frequency of recurrence.

Abstract
Helicobacter pylori (HP) is recognized as a common chronic human bacterial infection and is the most common cause of gastritis. Recent studies suggest an increased HP prevalence in patients with various extra-digestive inflammatory diseases. Since many respiratory diseases are characterized by chronic inflammation as well as increased immune response, and HP may enter the nasopharyngeal cavity by gastroesophageal reflux, an association between respiratory disorders and HP infection has been suggested. Several studies discover HP in clinical samples from the patients with upper respiratory system infections. Even some of them revealed a relief after the treatment directed to HP eradication. However some studies do not support this theory and whether this association means a definite proof of a causal relationship between HP and respiratory diseases needs to be clarified. In this study, we aimed to review the reports about the role of HP in upper respiratory system infections.

Abstract
BACKGROUND Recurrent aphthous stomatitis is one of the most common lesions of oral mucosa. Helicobacter pylori is suggested as one of the etiological agents of recurrent aphthous stomatitis. Here, we conduct a study for evaluating the impact of H. pylori eradication on clinical course of recurrent aphthous stomatitis. METHODS Forty-six patients with minor aphthous lesions were enrolled. The number of RAS lesions at last 6 months and vitamin B(12) levels were recorded. All patients were detected for H. pylori with endoscopic biopsy. H. pylori was positive in 30 patients and negative in 16 patients. H. pylori-positive 30 patients received eradication therapy. Three months after therapy, patients were re-evaluated with urea breath test; 18 patients were negative (eradicated), and the remainders (12 patients) were positive (non-eradicated) for H. pylori. 6 months after eradication, vitamin B(12) levels and number of aphthous lesions at 6 months were recorded. RESULTS Vitamin B(12) levels were significantly increased in H. pylori-eradicated group (P = 0.001), whereas no significant change was found in non-eradicated group (P = 0.638). Mean number of aphthous lesions (per 6 months) of H. pylori-eradicated group was significantly decreased after eradication (P = 0.0001); in the non-eradicated group, no significant change was found (P = 0.677). In Hp-positive group, number of RAS lesions and vitamin B(12) levels were negatively correlated when evaluated both before and after eradication. CONCLUSIONS This study provides evidence to support the beneficial effect of H. pylori eradication in patients with recurrent aphthous stomatitis. The underlying mechanism might be the increase in vitamin B(12) levels after eradication.

Abstract
The aim of the present work is to identify the presence of Helicobacter pylori bacterium in samples of gastric mucosa fragments, obtained by gastric biopsy, from Brazilian patients with peptic ulcer and chronic gastritis and also to determine differences among the prevalent strains in these two diseases by urease C and urease B genes amplification utilizing nested polymerase chain reaction (PCR) and PCR. We encountered 17 genotyping patterns for urease C and 7 for urease B and, although no significant differences were found among the patterns encountered for both diseases, we found predominant groups for each disease. Typing methods of the products obtained by nested PCR and PCR show a functional scheme and are of great importance for epidemiologic studies and H. pylori strain characterization, in addition to allowing correlation among the several strains and their role in the diseases caused by this microorganism.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) has been suggested to be associated with recurrent aphthous stomatitis (RAS) as well as many other diseases. METHODS We conducted a prospective study on a total of 23 patients with RAS to investigate the relationship between H. pylori and RAS as well as the effect of eradication therapy on the recurrence. All patients underwent endoscopic examination and gastric biopsy. The biopsy materials were examined histopathologically whether they contained H. pylori or not. The density of H. pylori was also noted. The patients with H. pylori infection were followed up for up to 1 year after starting the eradication therapy. RESULTS Gastric mucosal H. pylori colonization was + in 39%, ++ in 39%, +++ in 9%, and - in 13% of the patients, respectively. There were statistically significant decreases in the recurrence rate and amelioration time of RAS by eradication therapy. There were no significant correlations among the intensity of H. pylori with the recurrence rate, number, diameter, and amelioration time of the lesions in 1-year follow-up. CONCLUSIONS We concluded that eradication of H. pylori may have reducing effects on the recurrence and amelioration period of the RAS.

This study was designed to investigate the impact of haematopoietic stem cell transplantation (HSCT) on Helicobacter pylori colonization of the oral mucosa by nested polymerase chain reaction (nested-PCR). Forty six consecutive patients submitted to HSCT and 46 healthy volunteers were included in the study. Oral swabs were taken from the oral mucosa of the patients and control group. The medical records of the patients were reviewed and the following information was retrieved: gender and age of the patient, donor gender, primary disease, stem cell source (bone marrow or blood stem cells), leukocyte, neutrophil and platelet counts, and chronic graft versus host disease (cGVHD) of salivary glands. The results demonstrated an increased frequency of H. pylori in the oral mucosa of HSCT patients compared to controls (rho = 0.002). The presence of H. pylori in the oral mucosa was not related to the severity of cGVHD. The median counts of platelet/mm3, leukocytes/mm3 and neutrophils/mm3 in the group of HSCT patients positive for H. pylori were not statistically different from those of the patients negative for it. In conclusion, the present study shows increased frequency of H. pylori in the oral mucosa of HSCT patients compared to non-transplanted healthy volunteers.

Abstract
Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is a common condition which is characterized by multiple recurrent small, round or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors typically presenting first in childhood or adolescence. RAS occurs worldwide although it appears most common in the developed world. The aetiology of RAS is not entirely clear. Despite many studies trying to identify a causal microorganism, RAS does not appear to be infectious. A genetic predisposition is present, as shown by strong associations with genotypes of IL-1beta; IL-6 in RAS patients, and a positive family history in about one-third of patients with RAS. Haematinic deficiency is found in up to 20% of patients. Cessation of smoking may precipitate or exacerbate RAS in some cases. Ulcers similar to RAS may be seen in human immunodeficiency virus disease and some other immune defects, and drugs, especially non-steroidal anti-inflammatory drugs and nicorandil may produce lesions clinically similar to RAS. Topical corticosteroids can often control RAS. However, the treatment of RAS remains unsatisfactory, as most therapies only reduce the severity of the ulceration and do not stop recurrence.

Abstract
Ulcers commonly occur in the oral cavity, their main symptom being pain. There are different ways to classify oral ulcers. The most widely accepted form divides them into acute ulcers--sudden onset and short lasting--and chronic ulcers--insidious onset and long lasting. Commonest acute oral ulcers include traumatic ulcer, recurrent aphthous stomatitis, viral and bacterial infections and necrotizing sialometaplasia. On the other hand, oral lichen planus, oral cancer, benign mucous membrane pemphigoid, pemphigus and drug-induced ulcers belong to the group of chronic oral ulcers. It is very important to make a proper differential diagnosis in order to establish the appropriate treatment for each pathology.

Abstract
BACKGROUND Considerable evidence indicates that serotonergic mechanisms, particularly the serotonin transporter (5-HTT) may be involved in psychological alterations. Recent findings have demonstrated that depression and stress are influenced by polymorphism of the promoter region of 5-HTT (5-HTTLPR) and that the short allele (S) is associated with reduced transcriptional efficiency resulting in reduced serotonin expression and uptake. As psychological and genetic factors have been implicated in the pathogenesis of recurrent aphthous stomatitis (RAS), the purpose of the present study was to investigate 5-HTTLPR polymorphism in patients with RAS compared with control subjects. METHODS Sixty-nine consecutive subjects affected by minor and major forms of RAS and 70 healthy volunteers were genotyped at 5-HTTLPR. The chi-square test was used for statistical analysis. RESULTS A significant increase in the genotype of SS (P = 0.05) and of the allele S (P = 0.04) in the group of RAS were observed. CONCLUSION Our findings demonstrate that RAS patients have a tendency to show polymorphism associated with anxiety-related traits.

Abstract
OBJECTIVE The aim of the current study was to investigate any association of Helicobacter Pylori (HP) in recurrent aphthous stomatitis (RAS) and the effect of eradication of the microorganism in the clinical course of the disease. STUDY DESIGN Forty-eight patients with RAS were included in the study. Twenty-six were women and 22 men, of average age 41.3 +/- 2.44. Thirty-four out of these 48 patients were HP positive and the rest 14 who were negative were used as a control group. The diagnosis of HP infection was based on the detection of specific immunoglobulin G (IgG), and immunoglubulin A (IgA) antibodies using the enzyme-linked immunoabsorbent assay technique in the serum and the saliva of the patients. In all HP carriers an eradication therapy was administered. After a 2-month period the patients were checked for HP status, using 13C-UBT. The follow up period was 6-12 months following the eradication therapy. RESULTS At entry patients with HP infection suffered from more severe symptoms compared with HP negative patients (P < 0.05). After the administration of HP eradication therapy, patients who had become negative showed a remarkable improvement (62.5%) with reference to recurrence of RAS as well as to symptom intensity. In 29.2% of patients symptoms had disappeared and in 33.3% of patients there was a decrease in both the frequency of recurrence and the intensity of symptoms. After the eradication treatment, the periods between recurrence of RAS in patients who had become negative were statistically significantly longer compared with those before treatment (P < 0.001). Another important observation was that patients who became negative after eradication therapy were of comparable clinical status with those who were HP negative from the beginning of the study (P > 0.05). CONCLUSIONS These findings support the concept of a potential association between RAS and HP.

Abstract
The cause of recurrent aphthous stomatitis (RAS) remains unknown despite considerable research. This article reviews the evidence for current theories regarding this disorder, including possible suspected relationships with microbial and immunologic factors, and presents medical diseases that mimic RAS lesions in certain patients. Topical management of the common form of minor RAS is described along with systemic therapy currently available to patients with severe forms of this disease.

Abstract
Reports on Helicobacter pylori and extragastric diseases have almost doubled this year compared with last year, bearing witness to the persistent scientific interest in this branch of Helicobacter-related pathology. Data belong increasingly to the area of vascular medicine, as well as hematology, dermatology, pediatrics and other fields. Unfortunately, these studies show overall controversial results, due to the impact of several confounding factors, and to the difficulty of recruiting homogeneous patient populations. Furthermore, many studies continue to be conducted on Helicobacter species other than H. pylori, focusing on animal models of gastroenterological illnesses which may retain strong similarities with human diseases. In this paper, taxonomy, detection and characterisation of Helicobacter spp. will be reviewed, together with the most important data issued this year on other Helicobacters and animal models.

Abstract
Helicobacter pylori is an important cause of many gastrointestinal disorders, ranging from chronic gastritis to gastric lymphoma and adenocarcinoma. The deoxyribonucleic acid-based assays have the potential to be a powerful diagnostic tool given its ability to specifically identify H. pylori deoxyribonucleic acid. Markers used to include general H. pylori structures and pathogenetic factors like ureaseA, cagA, vacA, iceA. Deoxyribonucleic acid or bacterial ribonucleic acid for polymerase chain reaction assays can be collected from gastric biopsy, gastric juice, stool, buccal specimens. Polymerase chain reaction can yield quantitative and genotyping results with sensitivity and specificity that approaches 100%. A clear trend in the direction of the determination of quantitative H. pylori infection by real-time polymerase chain reaction can be observed. Fluorescent in situ hybridization is suggested for routine antibiotic resistance determination. To identify the organism, deoxyribonucleic acid structure and its virulence factors may be feasible by using oligonucleotide microarray specifically recognizing and discriminating bacterial deoxyribonucleic acid and various virulence factors. Deoxyribonucleic acid-based H. pylori diagnosis yields higher sensitivity, however, specificity requires sophisticated labour environment and associated with higher costs.
