Abstract
Background Helicobacter pylori is assumed to cause many gastric and extragastric diseases. We aimed to assess the possible association role of H. pylori in Otitis media with effusion (OME), nasal polyps and adenotonsillitis. Patients and Methods A total of 186 patients with various ear, nose and throat diseases were included. The study comprised 78 children with chronic adenotonsillitis, 43 children with nasal polyps and 65 children with OME. OME patients were assigned to two subgroups: those who have and those who did not have adenoid hyperplasia. Among the patients with bilateral nasal polyps, 20 individuals had recurrent nasal polyps and 23 had de novo nasal polyps. Patients who have chronic adenotonsillitis were divided into three groups: those with chronic tonsillitis and those who underwent tonsillitis, those with chronic adenoiditis and adenoidectomy was performed, and those with chronic adenotonsillitis and underwent adenotonsillectomy. In addition to examination of H. pylori antigen in stool samples of all included patients, real-time polymerase chain reaction (RT-PCR) for detection of H. pylori in the effusion fluid was performed, additionally, Giemsa stain was used for detection of H. pylori organism within the tissue samples when available. Results Frequency of H. pylori in effusion fluid was 28.6% in patients with OME and adenoid hyperplasia, while in those with OME it was only 17.4% with a p value of 0.2. Nasal polyp biopsies were positive in 13% patients of denovo, and 30% patients with recurrent nasal polyps, p=0.2. De novo nasal polyps were more prevalent in the positive stools than recurrent ones, p=0.7. All adenoid samples were negative for H. pylori, only two samples of tonsillar tissue (8.3%) were positive for H. pylori, and stool analysis was positive in 23 patients with chronic adenotonsillitis. Conclusion Lack of association between Helicobacter pylori and occurrence of OME, nasal polyposis or recurrent adenotonsillitis.

Abstract
OBJECTIVES To detect Helicobacter Pylori [HP] in tonsillar tissue of recurrent tonsillitis cases and assess the possible role of Laryngopharyngeal reflux [LPR] in tonsillar HP infection. METHODS A prospective study was done on the cited subject in a sample size of 50 paediatric patients [Age group: 6-18 years] suffering from recurrent tonsillitis. LPR was diagnosed by Reflux Symptom index [RSI] and Reflux Finding score [RFS]. A score of more than 7 and 13 was regarded as significant for RFS and RSI respectively. Patients with both scores significant were regarded to be suffering from LPR. Tonsillar specimen after tonsillectomy were subjected to urease test, histopathology [ Modified Giemsa Staining] and culture to detect HP. A minimum of two positive tests of the mentioned three were taken as gold standard to diagnose colonization of HP. Tabulated data was statistically analysed. RESULTS We recorded an incidence of 9% [18 cases] for LPR in recurrent tonsillitis. No case of HP colonization of tonsils was detected in this case series, even in patients of LPR. CONCLUSION We conclude that tonsils are not an extra gastric reservoir of HP. In addition, there is no aetiological relationship between recurrent tonsillitis and HP. And lastly, LPR is not a significant factor for colonization of tonsils by HP.

Abstract
AbstractObjective:To identify Helicobacter pylori infection in tonsillar tissue samples from patients undergoing tonsillectomy for chronic tonsillitis versus tonsillar hypertrophy, and to assess the possible relationships between H pylori and patients’ sociodemographic data and laryngopharyngeal reflux.Methods:In this prospective study, 97 patients who underwent tonsillectomy were divided into the following 2 groups: patients with chronic tonsillitis (n = 62) and patients with tonsillar hypertrophy (control group; n = 35). H pylori infection in the tonsillar biopsy samples was identified using histochemical and rapid urease tests.Results:The incidence of H pylori infection was significantly higher in the chronic tonsillitis group (56.5 per cent) compared to the control group (31.4 per cent). Similar findings were obtained for both subgroups of adults (68.6 vs 42.3 per cent) and children (40.7 vs 0.0 per cent). Significant relationships between a positive H pylori finding and laryngopharyngeal reflux related signs of vocal fold oedema, diffuse laryngeal oedema and hypertrophy of the posterior commissure were revealed.Conclusion:H pylori infection may be related to chronic tonsillitis and laryngopharyngeal reflux.

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
Helicobacter pylori (H. pylori) has long been found to cause gastric diseases such as gastritis, gastric ulcers and gastric cancer. The transmission medium of this bacterium has yet to be determined, though several studies have speculated that the oral cavity is a reservoir for H. pylori. Others have also reported that the oral cavity may be a source of both transmission and gastric reinfection; however, such results are controversial. We reviewed the literature and selected studies that report an association among H. pylori detections in the oral cavity (dental plaque, saliva, tongue, tonsil tissue, root canals, oral mucosa) in humans and in animals, as well as in the human stomach. The oral cavity may be considered the main reservoir for H. pylori. There are a correlations between H. pylori infection in the oral cavity and periodontal disease, oral tissue inflammation, H. pylori transmission, and gastric reinfection. We believe that the mouth is a reservoir and that it plays a crucial role in both H. pylori transmission and gastric infection.

Associations between peripheral vertigo and gastroesophageal reflux disease. Med Hypotheses 2015; 85:333-5.

Abstract
We hypothesize that peripheral vertigo is associated with gastroesophageal reflux disease (GERD). Two mechanisms could be considered – gastric acids may directly irritate the respiratory mucosa and cause inflammation, or Helicobacter pylori (H. pylori) could be present and cause local infection. Reflux material (Hydrochloric acid (HCl) and pepsin) could get into the middle ear via Eustachian tube and affect osseous structures directly. Disturbance of ossicles could cause tinnitus, which is more common for peripheral vertigo. H. pylori could also get in the esophagus and in the upper respiratory tract via gastroesophageal reflux, and could cause tympanosclerosis and fixation of ossicles. In our study group, 120 of 153 (78.4%) patients had gastroesophageal reflux disease (GERD). Diagnostic tests of H. pylori (rapid urease test or blood antibody test) were performed for 96 of 120 (80%) patients with GERD and were found positive for 32 of 96 (33.3%) patients. Peripheral vertigo was present in 93 of 120 (77.6%) patients with GERD compared to 33 of 126 (26%) patients without GERD (χ(2)=9.016, p=0.003). H. pylori and peripheral vertigo coexisted in 26 of 126 patients (20.6%) (OR 1.36; 95% CI 0.49-3.74, p=0.55). Our study demonstrated statistically significant association between peripheral vertigo and GERD but not between peripheral vertigo and H. pylori. Further more extensive investigations are needed in order to explore our hypothesis.

Abstract
Introduction There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp) in adenotonsillar tissue. Objective A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. Methods Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients’ serum by using polymerase chain reaction. Results Hp IgG was detected in 57 (89%) patients’ serum. A total of seven tissue samples from 64 patients (10.9%) were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. Conclusion This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas.

Abstract
OBJECTIVES The aim of this pilot study was to investigate an association between laryngopharyngeal reflux detected by combined multiple intraluminal impedance and pH monitoring and Helicobacter pylori in adenoid hyperplasia detected with real time polymerase chain reaction (PCR). METHODS The study group consisted of 30 children (median age 5.34 years) with extraesophageal symptoms of gastroesophageal reflux disease with adenoid hyperplasia. All children underwent adenoidectomy with subsequent PCR detection of H. pylori DNA in the tissue and multiple intraluminal impedance and pH monitoring. The most proximal impedance sensor was located 1cm caudal to the entrance of the oesophagus. RESULTS We found significant differences in the number of reflux episodes among patients with PCR positivity (median 35) and negativity (median 0) of H. pylori (p-value of Mann-Whitney U-test 0.0056). Patients with PCR positivity of H. pylori had significantly more reflux episodes reaching the upper oesophageal sphincter (p-value of Mann-Whitney U-test 0.023). The absence of reflux episode was the only independent factor for PCR negativity of H. pylori in the multiple logistic regression model. CONCLUSIONS These results support the hypothesis that reflux episodes reaching the upper oesophageal sphincter may play an important role in the transmission of H. pylori into lymphoid tissue of the nasopharynx and thus may contribute to adenoid hyperplasia in children.

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.

Abstract
CONCLUSION Our results encourage the notion that the pharynx could be an extragastric reservoir of Helicobacter pylori (HP). The study confirmed the presence of HP in adenotonsillar tissue in children. It could have importance in the pathophysiology of upper respiratory diseases. However, its precise role in these processes remains unclear and requires further studies. OBJECTIVE A prospective study was carried out to evaluate the presence of HP in tonsillar and adenoid tissue in children. The study focused on real-time PCR analyzing CagA and VacA genotypes of HP strains. METHODS A total of 37 consecutive pediatric patients with adenotonsillar hypertrophy indicated for surgery were observed in a prospective study. Adenoidectomy and/or tonsillectomy was performed in each patient; 49 specimens were taken, 32 from adenoids and 17 from tonsils. The presence of HP and its genotype were tested in all samples by real-time PCR analysis. RESULTS Of 49 samples analyzed, 48 were positive for the presence of HP (98%), so only 1 sample was negative. While the genotype VacAs1bm2 was definitely dominant in adenoid tissue, wider distribution was observed in tonsillar tissue. Cag(+) strains represented one-fifth of all samples (21%).

Abstract
BACKGROUND There are insufficient data in the literature on the presence of Helicobacter pylori in tonsil and adenoid tissue of patients with only airway obstruction. This study examined the presence of H. pylori in surgical cases with airway obstruction or recurrent infection. AIMS To investigate the relationship between H. pylori adenotonsillar colonisation and the frequency of adenotonsillitis and to compare paediatric and adult patients according to H. pylori tonsillar colonisation. STUDY DESIGN Prospective clinical trial. METHODS PATIENTS SCHEDULED FOR ADENOIDECTOMY OR TONSILLECTOMY WERE CLASSIFIED INTO THREE GROUPS BASED ON INDICATIONS: paediatric infection (n=29), paediatric obstruction (n=29) and adult infection (n=12). Tissue samples obtained from patients were examined for the presence of H. pylori by culture, rapid urease test and polymerase chain reaction. RESULTS Forty-nine tonsil tissues were examined. Positive results were found in two specimens with the rapid urease test (4.1%) and three with polymerase chain reaction examination (6.1%). Only three positive polymerase chain reaction results (5.8%) were identified in 52 adenoid tissue samples. There were no statistically significant differences in the presence of H. pylori between paediatric infection and obstruction groups or between paediatric infection and adult infection groups. CONCLUSION In our study, there was a low incidence of H. pylori colonisation in tonsil and adenoid tissues. Regarding H. pylori colonisation, there was no significant difference between paediatric infection and obstruction groups. Also, no significant difference was found between adult and paediatric cases.

Abstract
Helicobacter pylori, a well-known gastric pathogen, has been detected in the oral cavity and oropharynx in tonsillar tissue. In our study, the presence of H. pylori in the tonsillar tissue of patients with chronic tonsillitis and sleep apnoea syndrome (SAS) was investigated. The aim was to detect and genotype H. pylori for a collection of data supporting the possible role of H. pylori in the aetiology of chronic tonsillitis and SAS. Helicobacter pylori was detected by real-time polymerase chain reaction (rt-PCR). 89 patients, 60 with a diagnosis of chronic tonsillitis and 29 with SAS, were tested. In the chronic tonsillitis group, Helicobacter was detected in 48 (80 %) specimens, cagA gene was detected in 12 samples (25 %) and 12 samples were negative. In SAS group, Helicobacter was found in 24 samples (82.76 %), cagA gene was detected in 5 (20.83 %) and 5 samples (17.24 %) were negative. Helicobacter pylori-specific immunoglobulins were tested by ELISA in the serum of 57 patients only with 41 (71.93 %) showing positive. Our results on H. pylori DNA detection and H. pylori seropositivity show 26.32 % discrepancy, slightly in favour of rt-PCR (15.79 % compared to 10.53 %). The H. pylori presence in tonsillar tissue does not depend on the type of oropharyngeal disease (p = 0.756). This study shows that oropharynx constitutes an extragastric reservoir of H. pylori infection which could serve as an aetiopathogenetic factor for chronic tonsillitis and tonsillar hyperplasia by SAS. No conclusion has yet been drawn about the mechanism of the process.

Abstract
Background: Occasionally, bacteria or viruses enter the tonsils and these organs become overwhelmed by bacterial or viral infection leading to inflammation. Some studies confirmed the presence of Helicobacter pylori in tonsillar specimens of patients suffering from chronic tonsillitis and some others did not. The difference in results in various studies might be due to different laboratory methods. The aim of this study was to investigate the presence of H. pylori Deoxynucleic acid (DNA) in archival tonsillar tissues of patients with chronic tonsillitis by a rapid, sensitive, and specific technique of Scorpion real-time polymerase chain reaction (PCR). Materials and Methods: Scorpion real-time PCR and modified McMullen's staining was performed on 103 archival paraffin-embedded tonsillar samples collected from patients with chronic tonsillitis following tonsillectomy operation. Results: Our findings showed that H Cell and Molecular Research Center. pylori DNA was present in 21.35% of total specimens by using Scorpion real-time PCR. Modified McMullen's staining of paraffin-embedded sections was positive in 19 patients. Out of our 103 samples, 50 samples showed positive a rapid urease test whereas 53 samples demonstrated negative results, 20 produced positive PCR results, and 83 were negative for H. pylori. There was no significant relationship between the presence of H. pylori, sex, age, and place of residence. Conclusion: Although the existence of H. pylori in tonsillar tissue samples of patients with chronic tonsillitis is controversial, however, our results showed that in our studied specimens, a significant number of patients with chronic tonsillitis had H. pylori colonization.

Abstract
Background: Helicobacter pylori is capable of inducing systemic inflammatory reactions through immunological processes. There are several methods to identify the presence of H. pylori in clinical samples including rapid urease test (RUT), conventional polymerase chain reaction (PCR), and the Scorpion real-time PCR. Aim: The aim of the present study is to compare the agreement rate of these tests in identifying H. pylori in tonsillar biopsy specimens collected from patients with chronic tonsillitis. Materials and Methods: A total of 103 tonsil biopsy samples from patients with clinical signs of chronic tonsillitis were examined with RUT, PCR, and Scorpion real-time PCR. The degree of agreement between the three tests was later calculated. Results: There was a poor degree of agreement between RUT and PCR and also RUT and Scorpion real-time PCR (Kappa=0.269 and 0.249, respectively). In contrast with RUT, there was a strong degree of agreement between PCR and Scorpion real-time PCR (Kappa=0.970). Conclusion: The presence of a strong agreement between the Scorpion real-time PCR and PCR as well as its technical advantage over the conventional PCR assay, made the Scorpion real-time PCR an appropriate laboratory test to investigate the presence of H. pylori in tonsillar biopsy specimens in patients suffering from chronic tonsillitis.

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
To investigate whether there is any association between nasopharyngeal reflux and adenoid hypertrophy in children by using 24-h pH monitoring with dual probe and to determine whether Helicobacter pylori simply colonises in adenoid tissue or it is present there temporarily due to extraesophageal reflux. A prospective study at a tertiary referral center. Thirty-two patients who underwent adenoidectomy, aged ranged between 4 and 13 were included. All children with adenoid hypertrophy underwent 24-h pH monitoring with a dual probe. Proximal probe was placed in the nasopharynx. The presence of nasopharyngeal reflux and gastroesophageal reflux were investigated by 24-h pH monitoring. The presence of H. pylori was investigated in adenoidectomy samples by HP-fast test. Of the 32 patients who underwent adenoidectomy, 5 had nasopharyngeal reflux positivity while 27 patients did not show nasopharyngeal reflux positivity with pH monitorisation. Helicobacter pylori could not be detected in 5 nasopharyngeal reflux positive children while 3 of 27 nasopharyngeal reflux negative children showed H. pylori positivity, one of them in the mucosa and others in the core. This study demonstrated the high incidence of nasopharyngeal reflux and gastroesophageal reflux in adenoid hypertrophy and the possible colonisation of H. pylori in the adenoid tissue. This may change the assesment of children with adenotonsillar hypertrophy in near future. However, more placebo controlled and double blind studies and larger series are still needed to support this hypothesis.

Abstract
OBJECTIVE Contradictory results have been reported regarding Helicobacter pylori (H. pylori) detection in adenotonsillar tissue. The aims of this study were to investigate whether adenotonsillar tissue of symptomatic children with chronic adenotonsillitis harbors the H. pylori organism, using two biopsy-based invasive methods namely; rapid urease test (RUT) and polymerase chain reaction (PCR) as well as blood serology and to compare the results obtained from each of these methods to the "gold standard". METHODS This prospective clinical study was carried out on 20 children aged between 2 and 10 years scheduled for tonsillectomy +/- adenoidectomy in a tertiary referral center. Exclusion criteria included: use of antacids, H(2) blockers or antibiotics during the previous month before surgery and adenotonsillectomy for obstructive sleep apnea. Core biopsy samples from resected adenotonsillar tissue was tested for H. pylori detection using both RUT and PCR assay for the ureC gene. Preoperative patient venous blood samples were also tested for H. pylori IgG antibodies. As a "gold standard", examined tissue was considered to be H. pylori infected if the two biopsy specimen-based methods (RUT and PCR) yielded positive results. RESULTS Thirty adenotonsillectomy specimens were tested (20 tonsils and 10 adenoids). RUT was positive in 16 (53.3%) specimens (12 tonsils and 4 adenoids). According to the "gold standard", 11/16 were considered false-positive, yielding this test sensitivity 100% and specificity 56%. The ureC gene sequence was detected by PCR in 5 (16.6%) specimens (3 tonsils and 2 adenoids), all of which were also positive by RUT, thus were considered H. pylori infected. Accordingly, PCR had a 100% sensitivity and specificity. Serology testing was positive for H. pylori IgG antibodies in 4/20 patients (20%), only two of them were found to have H. pylori infected adenotonsillar tissue. CONCLUSIONS Based on our findings it seems that adenotonsillar tissue may constitute an extra-gastric reservoir for H. pylori in symptomatic children with chronic adenotonsillitis. RUT was found to be of less accuracy than PCR in H. pylori detection in an extra-gastric location, thus results of previous studies using this test alone for detection of oral H. pylori should be treated with caution.

Abstract
For two decades, Helicobacter pylori has been considered as the culprit in many extragastric manifestations. However, for several of these supposed associations the hypothesis of an etiological role has not yet been fully investigated. This may be due to a series of factors linked to the epidemiological features of the studies and to the diseases investigated. This review attempts to highlight the main reported associations of H. pylori with extragastric manifestations during the last year. The most convincing data arise in the field of idiopathic thrombocytopenic purpura (ITP) and sideropenic anemia. Long-term follow-up studies have shown that 50% of subjects with ITP maintain a hematological response after H. pylori eradication. There is also growing evidence of the role of H. pylori in other diseases, including ischemic heart disease even though results are not conclusive.
