Abstract
BACKGROUND Helicobacter pylori (H. pylori) has definite or possible associations with multiple local and distant manifestations. H. pylori has been isolated from multiple sites throughout the body, including the nose. Clinical non-randomized studies with H. pylori report discrepant data regarding the association between H. pylori infection and nasal polyps. The aim of this first systematic review and meta-analysis was the assessment of the strength of the association between H. pylori infection and incidence of nasal polyps. METHODS We performed an electronic search in the three major medical databases, namely PubMed, EMBASE and Cochrane, to extract and analyze data as per PRISMA guidelines. RESULTS Out of 57 articles, 12 studies were graded as good quality for analysis. Male-to-female ratio was 2:1, and age ranged between 17-78 years. The cumulative pooled rate of H. pylori infection in the nasal polyp group was 32.3% (controls 17.8%). The comparison between the two groups revealed a more significant incidence of H. pylori infection among the nasal polyp group (OR 4.12), though with high heterogeneity I2 = 66%. Subgroup analysis demonstrated that in European studies, the prevalence of H. pylori infection among the nasal polyp group was significantly higher than in controls, yielding null heterogeneity. Subgroup analysis based on immunohistochemistry resulted in null heterogeneity with preserving a statistically significant difference in H. pylori infection prevalence between the groups. CONCLUSION The present study revealed a positive association between H. pylori infection and nasal polyps.

Abstract
Many studies have described the detection of Helicobacter pylori (HP) in the nasal polyps; however, although gastroesophageal reflux has been associated with chronic rhinosinusitis and nasal polyps development, the role of HP remains unclear. Our aim was to describe the prevalence of HP detection in nasal polyps and its association with gastric HP infection and gastroesophageal reflux dsease (GERD). The prospective study involved 36 patients with nasal polyps, who underwent to endoscopic surgery removal of nasal polyps. Before surgical procedure all patients were tested for gastric HP infection by 13 C-urea breath test, while tissue samples from nasal polyps were tested for HP detection, using rapid urease test (CLO test) and histological examination with Giemsa stain. All patients were asked about GERD-related symptoms. HP in nasal polyps was detected in 9 out of 36 patients (25%) using histological examination with Giemsa stain, while the detection rate of HP was 30.5% (11/36) using CLO test. Furthermore, 28 out of 36 patients (77.7%) had gastric HP infection. All patients with HP colonization in nasal polyps had gastric HP infection and all patients with HP in nasal polyps reported symptoms related to GERD. HP was detected in approximately one out of three patients in nasal polyps, while all patients with HP detection in nasal polyps had concurrently gastric HP infection and reported GERD-related symptoms, suggesting a gastro-nasal route of HP.

Abstract
Nasal polyposis (NP) is an inflammatory disease of the paranasal sinuses and nasal cavity. The primary purpose of our study is to determine the expression of 5-HT7 receptors both in nasal polyps and in healthy tissue in the nasal cavity. The subsequent aim is to compare the expression of 5-HT7 receptors in patients with NP and in inferior turbinate tissue (control).The study included 60 participants (40 with NP and 20 controls) aged 35 to 62 years. Nasal polyp samples were collected from all patients and relative 5-HT7 receptor expression analyses were performed. RT-PCR analysis of nasal polyps and control tissue identified 5-HT7 receptor expression in the nasal cavities of controls. This expression was approximately 67 times higher in nasal polyp tissue than in healthy tissue. Our study identifies the expression of 5-HT7 receptors in the nasal cavity for the first time. It is also the first demonstration of increased 5-HT7 receptor expression in tissue from nasal polyps, which occur in the paranasal sinuses and nasal cavity.

Abstract
OBJECTIVE This study explored the impact of laryngopharyngeal reflux (LPR) on quality-of-life outcomes captured by Sino-Nasal Outcome Test (SNOT-22) and Reflux Symptom Index (RSI) in patients with chronic rhinosinusitis (CRS) and patients with symptoms of LPR. METHODS In a retrospective chart review, SNOT-22 and RSI scores were analyzed in patients seen at a tertiary care center with CRS, LPR, or both CRS and LPR. SNOT-22 items were grouped into sleep, nasal, otologic, and emotional symptom subdomains. RESULTS A total of 138 patients (36 with CRS alone, 60 with LPR alone, and 42 with both CRS and LPR) were included. Compared to patients with CRS alone, those with CRS and LPR (CRS+LPR) had higher SNOT-22 total (50.54 ± 19.53 vs 35.31 ± 20.20, P < .001), sleep (19.61 ± 9.31 vs 14.42 ± 10.34, P < .022), nasal (17.38 ± 7.49 vs 11.11 ± 8.52, P < .001), otologic subdomains (9.17 ± 5.07 vs 5.53 ± 5.14, P < .002), and RSI (22.06 ± 9.42 vs 10.75 ± 8.43, P < .003). Patients with LPR alone had higher RSI compared to those with CRS (18.48 ± 9.77 vs 10.75 ± 8.43, P < .037). RSI and SNOT-22 scores were positively correlated irrespective of patient group (R = 0.289, P = .003). CONCLUSION Compared to patients with CRS or LPR alone, those with CRS+LPR demonstrated higher RSI and total and subdomain SNOT-22 scores. Patients with LPR alone had elevated SNOT-22 despite absent endoscopic evidence of sinusitis.

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
To detect the presence of Helicobacter pylori in nasal polyps. A case-control study was conducted enrolling 35 patients with nasal polyps (cases) and patients undergoing septoplasty (controls). Fresh tissue samples were used for urea broth test and imprint cytology, while formalin fixed tissue sections were used for morphology, special stains and immunohistochemistry for H. pylori. Fresh stool samples from both groups were tested to correlate the gastrointestinal status. H. pylori was detected in 40.0 % (14/35) of cases and 8.5 % of controls (3/35) (p = 0.004) by immunohistochemistry. Amongst cases, eight were positive with urea broth test, six with imprint cytology (Giemsa stain), three with H & E, and nine with modified McMullen's stain. Hyperplasia of the lining epithelium and lymphoid aggregates were significantly noticed in nasal polyps positive for H. pylori. Stool antigen test was positive in subjects who were positive for H. pylori in the nasal mucosa. There appears to be an association between H. pylori and nasal polyps. Immunohistochemistry is more sensitive and specific method to detect H. pylori. H. pylori induced inflammatory tissue reaction pattern indicates a possible causal association. Further studies are needed to prove the causal relationship between H. pylori and nasal polyps.

Abstract
Background: Helicobacter pylori are becoming increasingly recognized as a possible pathological cause of chronic rhinosinusitis (CRS). Objectives: Considering the prevalence of CRS and its impact on quality of life, we decided to determine the role of H. pylori in chronic sinus infections by using the PCR technique. Patients and Methods: In a case-control analytical epidemiologic survey, the study population was selected by consecutive sampling from patients with CRS undergoing endoscopic sinus surgery during years 2010 - 2012. Patients were divided into two groups. The study group consisted of patients with CRS and the control group consisted of patients with nasal obstruction caused by concha bullosa, without inflammation or infection of the sinuses. Sampling was performed during surgery from the infected tissue and from the middle turbinate mucosa. Eventually, bacterial DNA was extracted and used for the PCR test, in order to isolate H. pylori. Results: Nine patients (18%) with CRS had H. pylori isolated from their samples whereas in the control group, H. pylori were only found in two patients (4%); this difference was statistically significant (P = 0.025). The indicator wasn’t statistically significant between males and females. There was no statistical correlation in relative frequency of H. pylori for different age groups (P > 0.05). Conclusions: There was a significant correlation between CRS and presence of H. pylori in sinonasal mucosa. This relationship may reflect the role of H. pylori as one of the pathogenic factors in the development of CRS. However, further studies are required to confirm this role.

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
BACKGROUND AND AIMS Helicobacter pylori is the most common etiological factor of chronic infection worldwide. It has also been found in human dental plaques, mouth, saliva, tonsils and adenoid tissue, medial ear or nasal polyps and sinuses mucosa, as well in several benign and malignant lesions of the larynx and pharynx. The aim of the study was to investigate the association of H. pylori colonization in chronic rhinosinusitis and benign laryngeal diseases. METHODS The prospective, controlled study involved a series of 30 patients with nasal polyps and normal nasal mucosa and 30 patients with benign laryngeal diseases. Samples of 10-15 mg obtained from fresh tissues were used for nucleic acid purification. All samples were subjected to H. pylori ureA detection by the PCR H. pylori diagnostic test. Samples that were positive for ureA H. pylori gene were evaluated for cagA H. pylori gene. RESULTS H. pylori DNA (ureA gene) was detected in all patients with nasal polyps, concha bullosa and laryngeal diseases. Presence of H. pylori cagA gene was identified in 7 (23.3%) of 30 patients of H. pylori-positive larynx samples and no positive result was observed in nasal polyps and concha bullosa. CONCLUSIONS Our results reveal the presence of H. pylori DNA in nasal polyps, concha bullosa and benign larynx diseases. cagA-positive H. pylori was observed only in laryngeal tissues. These results may have implications for a possible role of H. pylori in laryngeal diseases.

Abstract
The aim of this study was to identify the presence of Helicobacter pylori in nasal polyp specimens of patients with nasal polyposis. A cross-sectional study with control group was performed on fresh tissue samples from 25 patients with nasal polyps, and 25 persons with concha bollusa (control group). Patients with symptoms of gastroesophageal reflux (GERD) were not enrolled. Samples were studied by three methods: polymerase chain reaction (PCR), culture, and urease test. All the diagnostic tests were negative for H. pylori in both the case and control groups. In conclusion, there was no association between H. pylori and nasal polyposis in patients without GERD signs or symptoms in our study, and further studies are needed to assess other potential factors that may influence the development of nasal polyposis.

Abstract
Nasal polyps are benign mucosal protrusions that expand into the nasal cavity. There are no any etiological factors that may explain the pathogenesis of nasal polyps but currently inflammation continues to be the major factor. As a result of inflammation, neutrophils become activated and migrate to the inflammatory area and form their bactericidal effects by producing free oxygen radicals. The objective of our study is to investigate the expression of myeloperoxydase enzyme, which is usually an indicator of leukocyte infiltration and is responsible in the formation of free oxygen radicals in polyp tissues and to determine its role in the pathogenesis of nasal polyps.

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.

Abstract
There is an ongoing dilemma about the pathogenesis of nasal polyp (NP). The etiology of NP is multifactorial. Reactive oxygen species and oxidative stress are also suggested to be among the possible factors in NP development. Glutathione-S-transferase (GST) is one of the important detoxifying enzymes. It is not known whether GST plays any role in NP development. We aimed to investigate the relationship between GST subgroup (GSTT1, GSTM1, and GSTP1) polymorphisms, and NP development. Seventy-five patients with NP with or without asthma (NP with asthma: 22, NP without asthma: 53) were used as a study group. As much as 167 healthy individuals were involved as the control group. NP diagnosis was made by nasal endoscopy and paranasal sinus computed tomography (CT). NP was defined as the presence of endoscopically visible bilateral polyps originated from the middle meatus to the nasal cavity and affecting more than one paranasal sinus confirmed by CT. Blood was collected in EDTA-containing tubes and DNA was extracted from the leukocytes. The genotyping of polymorphisms of GSTT1, GSTM1, and GSTP1 were done using real time polymerase chain reaction. Chi-square (chi(2)) and Fisher's (F) exact tests were used for statistical evaluation. A 2-fold increased risk of NP could be found in individuals with the GSTT1 null genotype (OR = 2.03, 95% CI = 1.03-4.011). The distribution of GSTM1 null genotypes was not significantly different between the NP patients and controls and there was also no significance between the GSTP1 genotypes and NP. In conclusion, GST gene polymorphisms may be important in pathogenesis of NP. Additional studies which include larger study groups in different geographic localizations may be more useful to evaluate association with GST polymorphism and NP.
