Low Prevalence of HSV-1 and Helicobacter pylori in HNSCC and Chronic Tonsillitis Patients Compared to Healthy Individuals. Diagnostics (Basel) 2023; 13:diagnostics13101798.

Abstract
Recent studies identified viral and bacterial factors, including HSV-1 and H. pylori, as possible factors associated with diseases such as chronic tonsillitis and cancers, including head and neck squamous cell carcinoma (HNSCC). We assessed the prevalence of HSV-1/2 and H. pylori in patients with HNSCC, chronic tonsillitis, and healthy individuals using PCR after DNA isolation. Associations were sought between the presence of HSV-1, H. pylori, and clinicopathological and demographic characteristics and stimulant use. HSV-1 and H. pylori were most frequently identified in controls (HSV-1: 12.5% and H. pylori: 6.3%). There were 7 (7.8%) and 8 (8.6%) patients with positive HSV-1 in HNSCC and chronic tonsillitis patients, respectively, while the prevalence of H. pylori was 0/90 (0%) and 3/93 (3.2%), respectively. More cases of HSV-1 were observed in older individuals in the control group. All positive HSV-1 cases in the HNSCC group were associated with advanced tumor stage (T3/T4). The prevalence of HSV-1 and H. pylori was highest in the controls compared to HNSCC and chronic tonsillitis patients, which indicates that the pathogens were not risk factors. However, since all positive HSV-1 cases in the HNSCC group were observed only in patients with advanced tumor stage, we suggested a possible link between HSV-1 and tumor progression. Further follow-up of the study groups is planned.

Is Helicobacter pylori colonization associated with chronic tonsillitis? - A meta-analysis and systematic review. Am J Otolaryngol 2022; 43:103515. [PMID: 35687938 DOI: 10.1016/j.amjoto.2022.103515] [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: 01/27/2022] [Revised: 05/18/2022] [Accepted: 05/30/2022] [Indexed: 11/23/2022]
Abstract
PURPOSE The aim of this study was to investigate the correlation between Helicobacter pylori colonization of tonsillar tissue in chronic tonsillitis and in noninfectious hyperplastic tonsils. MATERIALS AND METHODS All included studies investigated the presence of Helicobacter pylori in tonsillar tissue removed for infectious or noninfectious factors. Included studies must have used an accepted method of testing for Helicobacter pylori. We pooled six eligible studies to perform a traditional meta-analysis. RESULTS Six studies were included, including 462 patients. Helicobacter pylori does have a significant role in chronic tonsillitis compared with noninfectious indications for tonsillectomy for children population. Detection methods had effects on results. CONCLUSION The positive rate of Helicobacter pylori in chronic tonsillitis group was significantly higher than that in simple noninfectious group for the pediatric population, but not for adults. We suspected that chronic tonsillitis is likely to be relevant to Helicobacter pylori.

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
The bacteria Helicobacter pylori (H. pylori) have been identified in the extragastric tissues in the head and neck. The origin and pathogenicity of these bacteria in the head and neck are not known. Gastric reflux and nasal or oral routes are the possible modes of spread. In many sinonasal, pharyngeal, laryngeal, and middle ear disorders, laryngopharyngeal reflux has been identified as a contributing or causative factor. One possible mode by which laryngopharyngeal reflux may contribute is by seeding of the extragastric mucosa with H. pylori. The clinical significance of the discovery of H. pylori in extragastric tissues in the head and neck is unclear. There is no evidence of a pathologic or active role of H. pylori in otorhinolaryngological disorders. The suggestion that the sinonasal cavities and pharynx may serve as a reservoir for H. pylori and that reinfection of the stomach occurs after eradication therapy awaits further studies for confirmation. No connection was observed between H. pylori found in the stomach and H. pylori found in the head and neck. Also, these bacteria, found in the head and neck tissues, may be accidental or innocent bystanders that do not affect the pathways of otolaryngological and gastroduodenal diseases. This review examines the evidence for a possible relationship of H. pylori with otorhinolaryngological diseases.

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
Helicobacter pylori infection is acquired predominantly during childhood. Childcare promotes interpersonal contact and may be an important determinant of infection. The aim was to quantify the association between childcare attendance and H. pylori infection in childhood or adolescence. PubMed was searched up to July 2012 to identify eligible studies. The DerSimonian and Laird method was used to compute summary odds ratio (OR) estimates and 95% confidence intervals (CIs); heterogeneity was quantified with the I statistic and explained through stratified analyses and metaregression. Sixteen studies compared participants attending childcare with those not exposed. The summary OR was 1.12 (95% CI: 0.82-1.52, I=77.4%). Summary estimates were similar for crude and adjusted estimates, and higher when the infection was evaluated in children of 3 years or younger (OR=2.00, 95% CI: 0.94-4.29, I=55.0%). Studies based on the detection of stool antigens yielded higher estimates (OR=2.65, 95% CI: 1.24-5.66, I=36.4%). Those conducted in settings with a high prevalence of H. pylori infection yielded stronger associations (OR=1.44, 95% CI: 0.94-2.20, I=74.3%). In multivariate metaregression, there was no significant association with any of these variables; taking them into account contributed to a reduction of I to 67%. The role of childcare as a risk factor for H. pylori infection is confirmed by our results, especially in settings with a high prevalence of infection. However, the association was moderate, and the effect of the type of childcare setting or the duration or the intensity of exposure was seldom addressed, leaving considerable scope for improving our understanding of how this modifiable exposure contributes towards H. pylori infection.

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
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
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
We conducted a prospective study to investigate the possibility of Helicobacter pylori colonization on tonsillar and adenoid tissues. Our study group was made up of 84 consecutively presenting children aged 4 to 12 years who had undergone adenotonsillectomy or adenoidectomy with or without ventilation tube insertion. The excised specimens were analyzed by rapid urease testing and histopathologic examination to detect H pylori. Histologic sections were subjected to hematoxylin and eosin staining and Giemsa staining as performed in routine gastric biopsies. We found no H pylori colonization in any specimen. Therefore, we consider the possibility of H pylori colonization of adenotonsillar tissue unlikely, even though the authors of some recent studies have reported such a finding. Other means of detecting possible H pylori colonization in the upper aerodigestive tract rely on invasive biopsy procedures, which are difficult to use in clinical practice. Therefore, on the basis of our findings and our review of the literature, we conclude that looking for H pylori in the upper aerodigestive tract is not only clinically useless, but damaging, as well.

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 The transmission of the gastric pathogen Helicobacter pylori involves the oral route. Molecular techniques have allowed the detection of H. pylori DNA in samples of the oral cavity, although culture of H. pylori from these type of samples has been sporadic. Studies have tried to demonstrate the presence of H. pylori in adenotonsillar tissue, with contradictory results. Our aim was to clarify whether the adenotonsillar tissue may constitute an extra gastric reservoir for H. pylori. METHODS Sixty-two children proposed for adenoidectomy or tonsillectomy were enrolled. A total of 101 surgical specimens, 55 adenoid and 46 tonsils, were obtained. Patients were characterized for the presence of anti-H. pylori antibodies by serology. On each surgical sample rapid urease test, immunohistochemistry, fluorescence in situ hybridization (FISH) with a peptide nucleic acid probe for H. pylori, and polymerase chain reaction-DNA hybridization assay (PCR-DEIA) directed to the vacA gene of H. pylori were performed. RESULTS Thirty-nine percent of the individuals had anti-H. pylori antibodies. Rapid urease test was positive in samples of three patients, all with positive serology. Immunohistochemistry was positive in samples of two patients, all with negative serology. All rapid urease test or immunohistochemistry positive cases were negative by FISH. All samples tested were negative when PCR-DEIA for H. pylori detection was used directly in adenotonsillar specimens. CONCLUSIONS The adenotonsillar tissue does not constitute an extra gastric reservoir for H. pylori infection, at least a permanent one, in this population of children. Moreover, techniques currently used for detecting gastric H. pylori colonization are not adequate to evaluate infection of the adenotonsillar tissues.

Jabbari Moghaddam Y, Rafeey M, Radfar R. Comparative assessment of Helicobacter pylori colonization in children tonsillar tissues. Int J Pediatr Otorhinolaryngol 2009; 73:1199-201. [PMID: 19523691 DOI: 10.1016/j.ijporl.2009.05.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2009] [Revised: 05/05/2009] [Accepted: 05/07/2009] [Indexed: 01/13/2023]
Abstract
OBJECTIVE The objective was to survey the results of RUT (rapid urease test) in children tonsillar tissues. METHODS In a prospective clinical study 285 children (4-14 years) tonsillar tissue tested with RUT (rapid urease test) and histopathologic biopsy and simultaneously serum IgG Helicobacter pylori level was measured for all patients. RESULTS One hundred and thirteen patients (39.6%) were positive to H. pylori in histopathologic examination. Forty patients (14%) had positive RUT and 15 patients had positive serum IgG anti-H. pylori level. In 40 patients the results in both histopathology and RUT were positive (P=0.000) although in 172 patients the results in both histopatologhic and RUT were negative (P=0.000). CONCLUSIONS This study showed that H. pylori was present in tonsillar tissue and RUT is not sensitive enough for diagnosis of H. pylori in tonsillar tissue. Indicating that H. pylori has a possible role in reservoir of H. pylori in children.

Abstract
OBJECTIVE Evaluation of the possible relationship between chronic adenotonsillitis and Helicobacter pylori (HP). PATIENTS AND METHODS The study was performed prospectively on 91 pediatric patients who underwent tonsillectomy, adenoidectomy or adenotonsillectomy due to chronic tonsillitis and/or adenoiditis. The adenotonsillectomy specimens were examined for HP colonization by rapid urease test (RUT) and immunohistochemical evaluation. Before surgery, anti-HP IgG and IgA antibody titers were detected by enzyme linked immunosorbent assay (ELISA) test in venous blood samples of the patients. RESULTS The RUT was positive in only two of the adenoidectomy specimens (2.2%) and in none of the tonsillectomy specimens. A positive result was not detected in any tonsillectomy specimens using immunohistochemical examination. Serum IgG antibody was positive in 21 (23%) patients, IgA antibody was detected in 7 (7.69%) patients and both tests were positive only in 3 (3.29%) patients. CONCLUSION The results of this study suggested that HP would not colonize in tonsil tissue of patients with chronic tonsillitis.

Abstract
The review summarizes the articles published on Helicobacter pylori in children between April 2007 and March 2008. Evidence is emerging in different populations including developing countries that the prevalence of H. pylori is declining in all age groups. The reasons for this are unclear but it is unlikely that treatment of infection or improvement in socioeconomic conditions fully explains the decline. For the first time, differences in the inflammatory response between adults and children have been well characterized in a group of adults and children from Chile with similar levels of H. pylori infection. This study suggests that the reduced inflammatory response to H. pylori at a cellular level in children could be the consequence of an enhanced Treg cell response, which in turn down-regulates H. pylori-induced inflammation. The publication of the Paediatric European Register for Treatment of Helicobacter pylori study (PERTH) is important as it demonstrates the advantages of different centers working in collaboration for the benefit of children. It also highlights the fact that while bismuth-based treatment is more effective than proton pump inhibitor-based treatment in children, bismuth preparations are not widely available for use in children.
