AbstractObjectiveTo determine the prevalence of Helicobacter pylori infection in nasal biopsy specimens from patients with chronic rhinosinusitis with polyposis versus control patients, and to assess the correlations between H pylori infection identified in the nasal tissue and patients’ sociodemographic data and reflux-related symptoms and signs.MethodsNasal biopsy samples were taken from 75 adult patients who underwent nasal surgery for chronic rhinosinusitis with polyposis (clinical group, n = 45) and a deviated septum (control group, n = 30). H pylori infection was identified using histochemical and rapid urease tests.ResultsThe prevalence of intranasal H pylori infection was significantly higher in the clinical group (28.9 per cent) compared to the control group (3.3 per cent) (p = 0.005). A significant yet weak association was found between positive H pylori status and laryngopharyngeal reflux related hypertrophy of the posterior commissure of the larynx. No other correlations reached statistical significance.ConclusionH pylori infection is potentially related to chronic rhinosinusitis with polyposis. Further research is needed to clarify the role of H pylori as a risk factor for the development of sinonasal diseases and to examine its link with laryngopharyngeal reflux.

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.

Sjögren‘S Syndrome

Background and Aim: Lymphoid cell infiltration and destruction of exocrine glands, specifically lacrimal and salivary glands are characteristics of Sjogren’s syndrome (SS). An etiological role has been proposed for Helicobacter pylori (H. pylori), interacting in the clinical course and complications of SS (including gastric cancer and lymphoma). The aim of this study was to identify the probable correlation between H. pylori infection and Sjogren’s syndrome (SS). Methods: In this case-control study, ELISA method was used to determine serum level of IgA and IgM anti H. pylori antibody in 43 subjects with SS according to the international criteria and 95 healthy subjects as control. SPSS-17 was used to analyze data with t-test. P value <.05 were considered significant. Results: Serum level of IgM (34.9% vs. 10.5%, p-value= 0.001) and IgA (67.4% vs. 46.3% p value= 0.021) anti H. pylori antibody were significantly higher in SS patients compared to the control group. There was a positive correlation between age and H. pylori infection (r=0.2, Pvalue= 0.05). Conclusion: Patients with SS had a higher prevalence of H. pylori infection compared to the normal population. Eradication of H. pylori is recommended particularly in older patients with SS.

Nasal Mucociliary Clearance

AbstractObjectiveThis study aimed to examine nasal mucociliary clearance time in patients with Helicobacter pylori infection.MethodsFifty patients who were newly diagnosed with H pylori infection using gastric biopsy in the gastroenterology out-patient clinic, and 50 age- and gender-matched healthy adults who were admitted to the otorhinolaryngology out-patient clinic, were included in this study. After an otorhinolaryngological examination (anterior rhinoscopy and nasal endoscopic examination), the nasal mucociliary clearance time of each subject was calculated using the saccharine test.ResultsThe mean mucociliary clearance time was 06:29 ± 3:31 minutes (range, 00:55–15:19 minutes) in the control group and 10:12 ± 06:09 minutes (range, 01:28–32:00 minutes) in the study group. Comparisons of the two groups revealed a statistically significant difference (p = 0.002).ConclusionNasal mucociliary clearance time was significantly increased in patients with H pylori infection. The results suggest that H pylori infection may have an unfavourable effect on nasal mucociliary clearance.

The evidence on whether high-dose new generation proton pump inhibitors (PPIs) including rabeprazole and esomeprazole achieve a higher eradication rate of Helicobacter pylori has not been assessed. The primary comparison was eradication and adverse events (AEs) rate of standard (esomeprazole 20 mg bid, rabeprazole 10 mg bid) versus high-dose (esomeprazole 40 mg bid, rabeprazole 20 mg bid) PPIs. Sub-analyses were performed to evaluate the eradication rate between Asians and Caucasians, clarithromycin-resistance (CAM-R) strains, and clarithromycin-sensitivity (CAM-S) strains of different dose PPIs. We conducted a literature search for randomized controlled trials comparing high-with standard-dose esomeprazole and rabeprazole for H. pylori eradication and AEs. A total of 12 trials with 2237 patients were included. The eradication rate of high-dose PPIs was not significantly superior to standard-dose PPIs regimens: 85.3% versus 84.2%, OR 1.09 (0.86–1.37), P = 0.47. The high dose induced more AEs than those of the standard dose, but didn’t reach statistical significance (OR 1.25, 95% CI: 0.99–1.56, P = 0.06). Subgroup analysis showed that the difference in eradication rate of PPIs between high- and standard-dose groups were not statistically significant both in Asians (OR 0.99, 95% CI 0.75–1.32, P = 0.97) and Caucasians (OR 1.27, 95% CI 0.84–1.92, P = 0.26). Furthermore, there were similar eradication rates in CAM-S (OR 1.2; 95% CI 0.58–2.5; P = 0.63) and CAM-R strains (OR 1.08; 95% CI 0.45–2.56; P = 0.87) between the standard-and high-dose groups. High and standard dosages of new generation of the PPIs showed similar H. pylori eradication rates and AEs as well as between Asian versus Caucasian populations, with or without clarithromycin-resistance. However, further studies are needed to confirm.

Background: Primary Open-Angle Glaucoma (POAG) the most common form of glaucoma is a neurodegenerative disease, which is the third most common cause of blindness worldwide. It is estimated that 60 million people in the world are affected by this disease and 8.4 million are bilaterally blind. Among the various factors that have been implicated in the pathophysiology of this disease is infection with Helicobacter pylori (HP), a Gram-negative bacterium that is commonly found in stomach and present in approximately one-half of the world’s population. Establishment of such a causal correlation will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma. Objectives: To investigate the association between Primary Open-Angle Glaucoma (POAG) and Helicobacter Pylori infection and to observe fluctuations in intra ocular pressure after Helicobacter Pylori infection eradication. Design: Duration based, prospective observational study. Participants: 50 patients with documented Primary Open-Angle Glaucoma (POAG) as case group and 50 non-glaucoma participants as control group. Methods: Upper gastrointestinal endoscopy was performed to evaluate macroscopic abnormalities, and gastric mucosal biopsy specimens were obtained for the presence of H. pylori infection tested by Rapid Urease Test (RUT). All subjects underwent detailed ocular examinations including visual acuity, slit-lamp examination, fundoscopy, intra-ocular pressure recording, gonioscopy, GHT to assess visual fields and OCT of optic nerve head. Results: In 90% of POAG patients of case group and in 68% of non-glaucoma participants of control group Helicobacter pylori infection was detected by RUT (P-Value=0.007). Conclusion: H. pylori infection is more frequent in glaucoma patients, perhaps more so in those of Indian ethnicity. It may play a role as a secondary aggravating factor or even may be the primary cause. The establishment of such a causal relationship will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma.

We previously reported that 3-pentylcatechol (PC), a synthetic non-allergenic urushiol derivative, inhibited the growth of Helicobacter pylori in an in vitro assay using nutrient agar and broth. In this study, we aimed to investigate the in vivo antimicrobial activity of PC against H. pylori growing in the stomach mucous membrane. Four-week-old male C57BL/6 mice (n = 4) were orally inoculated with H. pylori Sydney Strain-1 (SS-1) for 8 weeks. Thereafter, the mice received PC (1, 5, and 15 mg/kg) and triple therapy (omeprazole, 0.7 mg/kg; metronidazole, 16.7 mg/kg; clarithromycin, 16.7 mg/kg, reference groups) once daily for 10 days. Infiltration of inflammatory cells in gastric tissue was greater in the H. pylori-infected group compared with the control group and lower in both the triple therapy- and PC-treated groups. In addition, upregulation of cytokine mRNA was reversed after infection, upon administration of triple therapy and PC. Interestingly, PC was more effective than triple therapy at all doses, even at 1/15th the dose of triple therapy. In addition, PC demonstrated synergism with triple therapy, even at low concentrations. The results suggest that PC may be more effective against H. pylori than established antibiotics.

Abstract Background Helicobacter pylori (H. pylori) infection is a major cause of chronic gastritis, peptic ulcer diseases and cancer. Genistein (4′,5,7-trihydroxyisoflavone), a tyrosine-specific-protein kinase inhibitor, has been shown to exert an anti-inflammatory property. The aim of this study was to examine the treatment effects of genistein and its mechanisms in rats with H. pylori infection. Methods Eighteen male Sprague-Dawley rats were divided into three groups (6 rats per group): (1) control group (Con); (2) H. pylori infected group (HP): the rats were inoculated with H. pylori (108− 1010 CFU/mL; 1 mL/rat.) for 3 consecutive days; and (3) HP + genistein group (HP + Gen): the rats were inoculated with H. pylori as above. Then, they were gavaged with genistein (16 mg/kg BW) for 14 days. Gastric tissue was used for the determination of nuclear factor (NF)-κB expression by immunohistochemistry (IHC), degree of apoptosis by the terminal deoxynucleotidyl transferasemediated dUTP nick-end labeling (TUNEL) reaction, and histopathology. Serum samples were used to measure the levels of tumor necrosis factor-alpha (TNF-α) and cytokine-induced neutrophil chemoattractant-1 (CINC-1). Results Rats in the HP group had significantly higher levels of pro-inflammatory mediators, NF-κB expression and apoptotic cells when compared with the Con group, and these markers significantly decreased in HP + Gen group when compared with the HP group. The histopathology of HP group showed moderate gastric inflammation and many HP colonization. Gastric pathology in HP + Gen group demonstrated the attenuation of inflammatory cell infiltration and H. pylori colonization. Conclusion Genistein exerted its gastroprotective effects through the reduction of pro-inflammatory mediators, nuclear receptor NF-κB expression and gastric mucosal apoptosis in rats with H. pylori-induced gastropathy.

Background: Studies have reported relationship between chronic  Helicobacter pylori infection and coronary artery disease (CAD). The  cytotoxin-associated gene A product (CagA) is an immunodominant protein which indicates infection with virulent H. pylori strains. Significant  associations of CagA-positive H. pylori strains with coronary artery disorders have been widely reported. H. pylori is also known to produce different heat shock proteins (HSPs) which can stimulate the production of specific  antibody against microbial proteins and capable of eliciting autoimmune reaction against human tissue expressing HSPs such as vascular  endothelial cells. The objectives of this study are to investigate the  association between H. pylori and CagA with coronary atherosclerosis and CAD, and to determine the possible role of H. pylori HSP60 protein in increasing the risk of CAD development. Methods: This study included 70 patients with stable angina and 70 age and gender-matched controls. Each group was evaluated by clinical history, physical examination, cardiac echocardiography (ECHO) and electrocardiography (ECG) with and without exercise. Fasting blood glucose, total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL) and triglycerides (TG) were estimated by automated enzymatic methods. H. pylori IgG, CagA IgG and HSP60 IgG were measured by enzyme-linked immunosorbent assay (ELISA) for both groups. Results: The seroprevalence of H. pylori infection was high in both groups; 75.7% in case and 68.6% in control (p=0.346). Serum IgG levels were significantly higher for CagA (p=0.028) and HSP60 (p<0.001) in cases than in controls. There was significant association between H. pylori and CagA IgGs in cases (p=0.007) but no association in controls (p=0.700). Higher HSP60 IgG level was significantly associated with both positive H. pylori IgG (p<0.001) and CagA IgG (p<0.001) in cases but no significant association was found with H. pylori (p=0.815) or CagA (p=0.332) IgG levels in the control group. Serum values were significantly higher for TC (p<0.001), TG (p<0.001) and LDL (p=0.004) while value for HDL was significantly lower (p<0.001) in H. pylori IgG-positive subjects (case and control). Conclusion: There is serological evidence that H. pylori infection may pose a significant risk factor for CAD. Since H. pylori can be eliminated by specific treatment, this may be a good preventive approach for CAD.Key words: H. pylori, coronary artery disease, CagA, HSP60, serology.

The aim of this study is to investigate the effect of gastric Helicobacter pylori colonization on nasal functions. The study enrolled patients (n = 100) who underwent endoscopy for gastroesophageal reflux disease. Patients with laryngopharyngeal reflux (LPR) were identified by Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). Patients were divided into 2 groups: LPR (+) (n = 64) H pylori (+), RSI > 13, RFS > 7; LPR (−) (n = 36) H pylori (+), RSI < 13, RFS < 7. Visual analog scale (VAS), sinonasal outcome test-22 (SNOT-22), peak nasal inspiratory flowmeter (PNIF), mucociliary clearance (MCC), and olfactory tests were used to evaluate the nasal functions. The average VAS for nasal obstruction, PNIF, and MCC did not differ significantly between the LPR (+) and LPR (−) groups ( P > .05). However, the average olfactory test scores were lower in the LPR (+) patients than the LPR (−) patients ( P < .05). Also, the SNOT-22 scores were significantly higher in LPR (+) patients than in LPR (−) ( P < .01). Nasal functions and symptom scores were also evaluated according to the H pylori grading. The PNIF, MCC, SNOT-22, and olfactory test results deteriorated as the gastric mucosal H pylori colonization increased ( P < .05). In conclusion, nasal functions differed between LPR disease and GERD only, while the density of H pylori colonization in the gastric mucosa had an effect on nasal function.

AbstractBackground and objectives:Chronic nonspecific pharyngitis is a chronic inflammation of the pharynx. It is found worldwide, and treatment is difficult. The underlying aetiopathogenesis is still controversial. The aim of this study was to investigate Helicobacter pylori seroprevalence in chronic nonspecific pharyngitis patients without other possible causative factors for chronic pharyngeal irritation and without H pylori gastric mucosal infection.Materials and methods:Forty-one patients with symptoms of chronic nonspecific pharyngitis and 30 healthy control subjects were enrolled in this prospective, controlled, clinical study. In both study and control groups, selected patients were shown to have gastric mucosa uninfected by H pylori, as demonstrated by the 14C-urea breath test. Comprehensive otorhinolaryngological examination did not elicit any factor contributing to the chronic pharyngeal complaint. Serum H pylori immunoglobulin G antibody titres were assayed using serum enzyme-linked immunosorbent assay. The difference between the study and control groups was analysed by the chi-square test (the likelihood ratio was used).Results:Thirty-two of the 41 patients (78 per cent) and 14 of the 30 control subjects (46.7 per cent) were found to be H pylori positive. Patients with chronic nonspecific pharyngitis were found to have a significantly higher rate of H pylori seropositivity than the control group (p = 0.016).Conclusion:These data may be important in developing future treatment strategies for chronic nonspecific pharyngitis.
