Abstract
Background: There are concerns that Helicobacter pylori eradication therapy may worsen kidney function in patients with decreased renal function. This study aimed to systematically review the literature regarding Helicobacter pylori eradication in patients with renal impairment. Methods: PubMed, the Cochrane Library, and Igaku Chuo Zasshi were searched for comparative studies on H. pylori eradication in patients with renal impairment. Results: Five articles were included in this systematic review. According to a randomized trial comparing a proton pump inhibitor (PPI) + clarithromycin + metronidazole and PPI + clarithromycin + amoxicillin in patients with decreased renal function, the incidence of acute renal failure was significantly lower in PPI + clarithromycin + metronidazole (2%: 1/44) than in PPI + clarithromycin + amoxicillin (18%: 8/44). The eradication rate in PPI + clarithromycin + metronidazole (92.5%) was significantly better than that in PPI + clarithromycin + amoxicillin (76.3%). According to four reports on eradication treatment using PPI + clarithromycin + amoxicillin in patients with and without decreased renal function, the eradication rates and adverse effects were similar in both groups. Regarding dose adjustment, three reports reduced the dose of antibiotics by half in patients with a creatinine clearance of 30 mL/min or less. Conclusions: The regimen with PPIs, clarithromycin, and metronidazole is recommended for renal impairment. The combination of PPIs, clarithromycin, and amoxicillin, at reduced doses depending on the renal function, is also a potential option.

Abstract
Much concern was directed towards the relationship between migraine and Helicobacter pylori (H. pylori) infection. Some researchers reported a strong association. Meanwhile, others have indicated totally negative results. The aim of this work was to clarify the association between migraine headaches and both H. pylori infection and Gastrointestinal (GIT) symptoms and to study their impact on the frequency and severity of migraine headache attacks. This is a case control study conducted on 77 migraine patients and 77 healthy controls. History was taken from the included patients regarding the frequency of migraine headache attacks/month and GIT symptoms including dyspepsia, flatulence, weight loss, and epigastric pain. Migraine Disability Assessment Test (MIDAS) and Visual Analogue Scale (VAS) were used for assessment of migraine severity. Helicobacter pylori was detected in the stool of the included patients and controls. There was a significantly higher prevalence of infection with H. pylori in migraine patients [77.9% (n = 60)] than control group [50.6% (n = 39)] (P-value˂ 0.001, Odds ratio= 3.439, 95% CI =1.708 - 6.923). The prevalence of dyspepsia, flatulence, and epigastric pain. was significantly higher in migraine patients in comparison to control group (P-value= 0.003, 0.017, 0.006 respectively). There was no effect of infection with H. pylori or presence of GIT symptoms on frequency of migraine attacks, MIDAS or VAS scores. GIT symptoms and H. pylori infection are more prevalent in patients with migraine compared to controls, however, they might not have an impact on the frequency or severity of migraine headache attacks.

Helicobacter pylori Infection: Current Status and Future Prospects on Diagnostic, Therapeutic and Control Challenges. Antibiotics (Basel) 2023; 12:191. [PMID: 36830102 PMCID: PMC9952126 DOI: 10.3390/antibiotics12020191] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 12/26/2022] [Accepted: 01/06/2023] [Indexed: 01/20/2023] Open
Abstract
Helicobacter pylori (H. pylori) infection, which affects approximately half of the world's population, remains a serious public health problem. As H. pylori infection leads to a number of gastric pathologies, including inflammation, gastroduodenal ulcers, and malignancies, early detection and treatment are crucial to preventing the spread of the infection. Multiple extragastric complications, such as iron deficiency anaemia, immune thrombocytopenic purpura, vitamin B12 deficiency, diabetes mellitus, cardiovascular diseases, and certain neurological disorders, have also been linked to H. pylori infection. An awareness of H. pylori and associated health hazards is necessary to minimize or even eradicate the infection. Therefore, there is an urgent need to raise the standards for the currently employed diagnostic, eradication, alternative treatment strategies. In addition, a brief overview of traditional and cutting-edge approaches that have proven effective in identifying and managing H. pylori is needed. Based on the test and laboratory equipment available and patient clinical characteristics, the optimal diagnostic approach requires weighing several factors. The pathophysiology and pathogenic mechanisms of H. pylori should also be studied, focusing more on the infection-causing virulence factors of this bacterium. Accordingly, this review aims to demonstrate the various diagnostic, pathophysiological, therapeutic, and eradication tactics available for H. pylori, emphasizing both their advantages and disadvantages. Invasive methods (such as quick urease testing, biopsy, or culture) or noninvasive methods (such as breath tests, stool investigations, or serological tests) can be used. We also present the most recent worldwide recommendations along with scientific evidence for treating H. pylori. In addition to the current antibiotic regimens, alternative therapies may also be considered. It is imperative to eradicate the infections caused by H. pylori as soon as possible to prevent problems and the development of stomach cancer. In conclusion, significant advances have been made in identifying and treating H. pylori. To improve eradication rates, peptide mass fingerprinting can be used as a diagnostic tool, and vaccines can also eliminate the infection.

Helicobacter pylori infection: is there circulating vacuolating cytotoxin A or cytotoxin-associated gene A protein? Gut Pathog 2022; 14:43. [PMID: 36463198 PMCID: PMC9719618 DOI: 10.1186/s13099-022-00519-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 11/18/2022] [Indexed: 12/07/2022] Open
Abstract
BACKGROUND Helicobacter pylori infection is a well-recognized cause of gastric diseases, including chronic gastritis, peptic ulcer, and gastric cancer. Vacuolating cytotoxin-A (VacA) and cytotoxin-associated gene A protein (CagA) play a role in the pathogenesis of H. pylori-related gastric diseases. Also, extragastric disorders are frequent morbid complications in patients with H. pylori infection. However, the direct pathologic implication of these virulence factors in extragastric manifestations remains unclear. Our hypothesis in the present study is that VacA and CagA released by H. pylori in the gastric mucosa leak into the systemic circulation, and therefore they can be measured in serum. RESULTS Sixty-two subjects were enrolled. They were allocated into the H. pylori-positive and H. pylori-negative groups. VacA and CagA were measured by immunoassays. The serum levels of VacA and CagA above an upper limit cut-off (mean plus two standard deviations of the mean in patients without H. pylori infection) were considered positive for antigen circulating level. Five out of 25 H. pylori-positive patients were positive for both serum VacA and serum CagA. The serum levels of VacA and CagA were significantly correlated with the serum levels of anti- H. pylori antibody and interleukin-12p70 among all H. pylori-positive and H. pylori-negative patients. CONCLUSIONS This study suggests that spill-over of VacA and CagA antigens in the systemic circulation may occur in some patients with H. pylori infection.

Abstract
OBJECTIVES To evaluate the impact of Helicobacter pylori eradication on venous thromboembolism (VTE) events, and the differences between early and late treatment timing. DESIGN A population-based cohort study. SETTING Taiwan's National Health Insurance Research Database. PARTICIPANTS A total of 6736 patients who received H. pylori eradication therapy from 2000 to 2010 were identified. We randomly selected 26 944 subjects matching in gender, age and baseline year as comparison cohort. PRIMARY AND SECONDARY OUTCOME MEASURES The incidence rate ratios of VTE in the H. pylori eradication cohorts to that of the control cohort were examined. Multivariable Cox proportional hazard regression analysis was used to estimate the relative HRs and 95% CI of VTE development. RESULTS The total incidence rate of VTE was observed in the late H. pylori eradication cohort, the early H. pylori eradication cohort and the control cohort (15.2, 3.04 and 2.91 per 1000 person-years, respectively). An age-specific trend was found in the late H. pylori eradication cohort, with a greater rate of VTE in the 50-65 years and more than 65 years age groups (adjusted HR 5.44; 95% CI 4.21 to 7.03 and 3.13; 95% CI 2.46 to 3.99). With comorbidities, the late H. pylori eradication cohort seemed to have the highest VTE incidence rate and adjusted HR (4.48, 95% CI 3.78 to 5.30). CONCLUSIONS Late H. pylori eradication was associated with a significantly increased risk of VTE, and there was a significantly greater risk of VTE in patients with female gender, age more than 50 years and with comorbidities.

Abstract
Helicobacter pylori is the first formally recognized bacterial carcinogen and the most important single digestive pathogen responsible for the induction of gastroduodenal diseases such as gastritis, peptic ulcer, and, finally, gastric neoplasia. The recently reported high rates of antimicrobial drug resistance hamper the current therapies of H. pylori, with therapeutic failure reaching up to 40% of patients. In this context, new treatment options and strategies are urgently needed, but the successful development of these new therapeutic tools is conditioned by the understanding of the high adaptability of H. pylori to the gastric acidic environment and the complex pathogenic mechanism. Due to several advantages, including good antibacterial efficiency, possible targeted delivery, and long tissular persistence, silver nanoparticles (AgNPs) offer the opportunity of exploring new strategies to improve the H. pylori therapy. A new paradigm in the therapy of H. pylori gastric infections using AgNPs has the potential to overcome the current medical limitations imposed by the H. pylori drug resistance, which is reported for most of the current organic antibiotics employed in the classical therapies. This manuscript provides an extensive overview of the pathology of H. pylori-induced gastritis, gastric cancer, and extradigestive diseases and highlights the possible benefits and limitations of employing AgNPs in the therapeutic strategies against H. pylori infections.

Abstract
Cholangiocarcinoma (CCA) is the most common malignant tumor of the biliary system with a very poor prognosis. The human microbiome, which is the sum of the genetic information of human microorganisms, plays an important role in regulating the digestion, absorption, immune response, and metabolism of the host. Increasing evidence indicates a close relationship between CCA and the human microbiome. Specific alterations occur in the human microbiome of patients with CCA. Therefore, in this review, we aimed to summarize the recent evidence on dysbiosis in the human microbiome of CCA. Then, we generalized the effect of Helicobacter pylori on CCA. Additionally, the potential mechanism of human microbial dysbiosis promoted the progress of CCA, and its precancerous disease was also explored. Furthermore, the possibility of the human microbiome as a diagnostic and therapeutic target of CCA was discussed.

Abstract
BACKGROUND Coronary artery disease (CAD) is a dilemma and a serious cause of morbidity and mortality worldwide. Since CAD has been seen in people without the conventional risk factors like smoking, diabetes, and hypertension, the infectious theory being a risk factor has arisen. MAIN BODY Helicobacter pylori (HP) infection is the most common infection affecting the vast majority of the population worldwide. HP grows in the gastrointestinal tract (GIT) and responsible for chronic gastritis, peptic ulcer, gastric adenocarcinoma, and gastric lymphoma. A review of medical literature mainly PubMed has revealed several studies reporting that HP pathogenesis extends beyond the GIT to be a predisposing factor for atherosclerosis, dyslipidemia, thrombosis, and CAD. However, it remains a controversial issue that warrants extensive research. CONCLUSION This article gives insight into the diversity of opinions, evidence, and theories regarding the association between HP infection and CAD. The idea that CAD may be managed with antibiotics in certain patients seems to be creative and inspiring. More research is mandatory to either verify or reject this proposed correlation with strong scientific evidence and also to demonstrate the implications of the results on CAD management and outcome.

Abstract
Introduction Hyperemesis gravidarum (HG) is a serious complication of pregnancy involving nausea and vomiting which affects all facets of the lives of many women. Helicobacter pylori infection has been linked to HG in some regions of the world. However, the prevalence of H. pylori in Saudi Arabian pregnant women and its link to HG has not been the subject of previous research. Detecting and treating H. pylori infection in women early in their pregnancies may lower the likelihood of adverse maternal outcomes. This study aims to assess the connection between the pathogenesis of HG and H. pylori infection in this population. Methods Forty-five pregnant women with HG were recruited from the outpatient clinic for antenatal care in the Gynecology and Obstetrics Department at King Abdulaziz University Hospital. Forty-five pregnant women without HG were matched as controls. Both groups underwent testing for the H. pylori antigen in stool samples. Results A statistically significant difference (P < 0.05) was observed between the cases and controls in terms of the occurrence of H. pylori. Thirty-eight women in the HG group (84.4%) tested positive for H. pylori, while the same was true of only 20 of the controls (44.4%). The mean level of blood hemoglobin in positive cases was significantly lower than that in negative cases (9.56 ± 1.29 vs. 11.90 ± 1.18 g/dl, P = 0.012). Conclusion H. pylori may play a contributing role in the presence of HG in the study population. It may be included with other investigations of HG, especially with cases that do not respond to conventional management and continue into the second trimester. Women with H. pylori were also more likely to suffer from anemia compared to those without the infection. For this reason, those working with pregnant women should pay close attention to those infected with H. pylori. Additional large case–control studies are necessary to better understand the part H. pylori plays and the pathogenesis of HG.

Abstract
Helicobacter pylori is a microorganism that in the last years has been associated with extragastric disorders such as respiratory diseases, however, its impact on lung is partially understood. The aim of this work was to study infection impact of H. pylori on the inflammatory markers expression at the pulmonary level using an animal model. Infection was performed by BALB/c wild type (WT) mice orotracheal instillation with 20 μl of 1 × 108H. pylori reference strain suspension once per day throughout 3 days. Inflammatory response was evaluated at 3, 7, 14, 21 and 30 days post infection. Lung was aseptically removed and pulmonary edema index values showed a significant change at 30 days of infection. Hematoxylin-Eosin (H-E) stain allowed to visualizing H. pylori presence in lung samples at 3 days of infection near the phagocytic cells or in the alveoli lumen. Bronchoalveolar lavage (BAL) was used for inflammatory response evaluation. Lactate dehydrogenase values showed a gradual increase in infected animals along infection time. Protein concentrations in mg/ml from BAL increased significantly at 7 days in infected animals. Macrophages viability obtained from BAL, decreased at the first moment of infection, maintaining constant values along contamination time. Results obtained demonstrate an inflammatory response in lung after orotracheal H. pylori infection and suggest that the pathogenic mechanism is strongly evidenced by tissue damage, endothelial dysfunction inflammatory mediators and markers expression at the pulmonary level.

Nutrients 2019; 11:nu11081874. [PMID: 31409000 PMCID: PMC6723734 DOI: 10.3390/nu11081874] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Revised: 08/06/2019] [Accepted: 08/09/2019] [Indexed: 02/07/2023] Open
Abstract
Helicobacter pylori (H. pylori) may be involved in diabetes and other insulin-related processes. This study aimed to investigate the associations between H. pylori infection and the risks of type 2 diabetes, impaired glucose tolerance (IGT), diabetic nephropathy, and poor glycemic control. We retrospectively evaluated 16,091 subjects without diabetes at baseline who underwent repeated health examinations. Subjects were categorized according to whether they were seropositive and seronegative for H. pylori infection. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazard models. The serological results were validated using an independent cohort (n = 42,351) based on a histological diagnosis of H. pylori infection. During 108,614 person-years of follow-up, 1338 subjects (8.3%) developed newly diagnosed diabetes, although the cumulative incidence of diabetes was not significantly related to serological H. pylori status. The multivariate Cox proportional-hazards regression models revealed that H. pylori seropositivity was not significantly associated with diabetes (HR: 1.01, 95% CI: 0.88–1.16; p = 0.854), IGT (HR: 0.98, 95% CI: 0.93–1.04; p = 0.566), diabetic nephropathy (HR: 0.99, 95% CI: 0.82–1.21; p = 0.952), or poor glycemic control (HR: 1.05, 95% CI: 0.90–1.22; p = 0.535). Similarly, histopathological findings of H. pylori infection were not significantly associated with diabetes (p = 0.311), diabetic nephropathy (p = 0.888), or poor glycemic control (p = 0.989). The findings from these large Korean cohorts indicate that there does not appear to be a role for past H. pylori infection in the development of diabetes, IGT, diabetic nephropathy, or poor glycemic control.

Abstract
The infection of Helicobacter pylori, covering 50% of the world-population, leads to diverse gastric diseases as ulcers and cancer along the life-time of the human host. To promote the discovery of biomarkers of bacterial infection, in the present work, Fourier-transform infrared spectra were acquired from adenocarcinoma gastric cells, incubated with H. pylori strains presenting different genotypes concerning the virulent factors cytotoxin associated gene A and vacuolating cytotoxin A. Defined absorbance ratios were evaluated by diverse methods of statistical inference, according to the fulfillment of the tests assumptions. It was possible to define from the gastric cells, diverse absorbance ratios enabling to discriminate: i) The infection; ii) the bacteria genotype; and iii) the gastric disease of the patients from which the bacteria were isolated. These biomarkers could fasten the knowledge of the complex infection process while promoting a platform for a new diagnostic method, rapid but also specific and sensitive towards the diagnosis of both infection and bacterial virulence.

[PMID: 29548703 DOI: 10.1016/j.pedneo.2018.02.007] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Revised: 12/26/2017] [Accepted: 02/07/2018] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Helicobacter pylori infection is associated with iron deficiency (ID) in children. Inflammatory cytokine reactions could influence the consequences of H. pylori infection. Hepcidin is an important regulator in iron homeostasis and could be induced by chronic inflammation. The relationship between hepcidin and cytokine levels in children infected with H. pylori remains controversial. METHODS Based on serology testing for anti-H. pylori IgG, participants (43 seropositive and 43 seronegative) aged 10-18 years were enrolled. Serum hepcidin levels and iron profiles, including iron, ferritin, and total iron-binding capacity, were measured. ID is defined as iron saturation less than 15%. Seropositive children were divided into low hepcidin (n = 22) and high hepcidin (n = 21) groups. IL-1β, IL-6, and IL-8 serum levels were compared. RESULTS Serum IL-1β and IL-6 levels were comparable between H. pylori seropositive and seronegative children, as were the median serum hepcidin levels (6.5 ng/mL versus 8.6 ng/mL; P = 0.1318). Median levels of serum iron, ferritin, and iron saturation were significantly lower in seropositive children with low hepcidin than in those with high hepcidin (P = 0.0123, P = 0.0001, and P = 0.0004, respectively). The prevalence of ID was significantly higher in those with low serum hepcidin levels (33.3% versus 4.5%; P = 0.015). Compared to the high hepcidin seropositive group, the low hepcidin group had significantly lower median serum levels of cytokines IL-1β and IL-6, but not IL-8 (P = 0.0151 and P = 0.0015, respectively). CONCLUSIONS Inflammatory cytokines IL-1β and IL-6, but not IL-8, might be associated with increased hepcidin levels among H. pylori-seropositive children. Further studies are needed to clarify the role of hepcidin.

Abstract
Helicobacter pylori infection is the principal cause of peptic ulcer disease, gastric adenocarcinoma and gastric mucosa-associated lymphoid tissue lymphoma. Recent studies have shown that it may interfere with many biological processes and determine or influence the occurrence of many diseases outside the stomach. Currently, the role of H. pylori in idiopathic thrombocytopenic purpura and iron deficiency anemia is well documented. Emerging evidence suggests that it may also contribute to vitamin B12 deficiency, insulin resistance, metabolic syndrome, diabetes mellitus and non-alcoholic liver disease. Additionally, it may increase the risk of acute coronary syndrome, cerebrovascular disease, neurodegenerative disease and other miscellaneous disorders. Different pathogenic mechanisms have been hypothesized, including the occurrence of molecular mimicry and the induction of a low-grade inflammation. This review summarizes the results of the most relevant studies on the extra-gastroduodenal manifestations of H. pylori infection.

Abstract
BACKGROUND To examine the association between dietary habits and Helicobacter pylori (H. pylori) infection among patients at a tertiary healthcare center in Lebanon. METHODS This cross-sectional study was conducted on 294 patients in 2016, at a hospital in Northern Lebanon. Participants were interviewed using a structured questionnaire to collect information on socio-demographic and lifestyle characteristics; dietary habits were ascertained via a short food frequency questionnaire (FFQ). H. pylori status (positive vs. negative) was determined after upper GI endoscopy where gastric biopsy specimens from the antrum, body, and fundus region were collected and then sent for pathology analysis. Multivariable logistic regression was conducted to identify the association between socio-demographic, lifestyle, dietary and other health-related variables with H pylori infection. RESULTS The prevalence of H. pylori infection was found to be 52.4% in this sample. Results of the multivariable analysis showed that H. pylori infection risk was higher among participants with a university education or above (OR = 2.74; CI = 1.17-6.44), those with a history of peptic ulcers (OR = 3.80; CI = 1.80-8.01), gastric adenocarcinoma (OR = 3.99; CI = 1.35-11.83) and vitamin D level below normal (OR = 29.14; CI = 11.77-72.13). In contrast, hyperglycemia was protective against H. pylori (OR = 0.18; CI = 0.03-0.89). No relationship between dietary habits and H. pylori infection was found in the adjusted analysis. CONCLUSIONS Socio-demographic and clinical variables are found to be associated with H. pylori, but not with dietary factors. Further studies are needed to investigate the effect of diet on H. pylori risk.

Abstract
We investigated the relationship of H. pylori stratified by cytotoxin-associated gene A (cagA) status with nonalcoholic fatty liver disease (NAFLD) in the general population of the United States (US). We utilized the Third National Health and Nutrition Examination Survey from 1988 to 1994 in this study. NAFLD was defined by ultrasonographic detection of hepatic steatosis in the absence of other known causes of liver diseases and significant alcohol consumption. Hepatic steatosis was assessed by parenchymal brightness, liver to kidney contrast, deep beam attenuation, bright vessel walls and gallbladder wall definition. Antibodies to H. pylori and cagA of participants were measured using H. pylori IgG and anti-cagA IgG enzyme-linked immunosorbent assays. Among 5,404 participants, the prevalence of NAFLD was higher in H. pylori positive subjects (33.5±1.8%) compared to H. pylori negative subjects (26.1±1.7%, p <0.001). In terms of cagA protein status stratification, while cagA positive H. pylori group did not demonstrate an association with NAFLD (OR: 1.05; 95% CI: 0.81-1.37), cagA negative H. pylori group was noted to have a significant association with NAFLD in a multivariable analysis (OR: 1.30; 95% CI: 1.01-1.67). In conclusion, our study demonstrated that cagA negative H. pylori infection was an independent predictor of NAFLD in the US general population.

Abstract
Background. Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder in which the immune system destroys native platelets. In this condition an autoantibody is generated against a platelet antigen. ITP affects women more often than men and is more common in children than adults. Objective. To assess the effect of Helicobacter pylori eradication therapy (HPET) on platelet count in Helicobacter pylori associated chronic immune thrombocytopenic purpura (chronic ITP) in adult. Materials and Methods. It is an interventional prospective study conducted at Liaquat University of Medical and Health Sciences, Jamshoro, from 2014 to 2015. A set of 85 patients diagnosed with chronic ITP were included in the study via convenient sampling. Patients with platelets count < 100 × 109/L for >3 months were selected. They were posed to first-line investigations which comprised complete blood count (CBC) and peripheral blood smear examination followed by second-line tests including bone marrow examination and Helicobacter pylori stool specific antigen (HpSA-EIA). Standard H. pylori eradication therapy was offered and the patients were assessed at regular intervals for 6 months. Results. Of the 85 study patients, 32 (37.6%) were male and 53 (62.3%) were female. Mean ages of H. pylori positive and negative subjects were 43.89 ± 7.06 and 44.75 ± 7.91 years, respectively. Bone marrow examination confirmed the diagnosis and excluded other related BM disorders. H. pylori stool antigen (HpSA) was detected in 34 (40%) patients and hence regarded as H. pylori positive; the rest were negative. Treatment with eradication therapy significantly improved the mean platelet counts from 48.56 ± 21.7 × 109/l to 94.2 ± 26.8 × 109/l. Conclusion. We concluded that the anti-H. pylori eradication therapy improves blood platelet counts in chronic immune thrombocytopenia.

Abstract
BACKGROUND Some studies have suggested that Helicobacter pylori (H. Pylori) infection was associated with insulin resistance and metabolic syndrome, which may increase the risk of chronic kidney disease (CKD). But there is no conclusive evidence regarding the association between H. Pylori infection and CKD. To help clarify this, we conducted the cross-sectional study to investigate the association of H. pylori infection with CKD among Chinese adults. METHODS A total of 22,044 adults aged 48.6 ± 14.3 years were enrolled. H. pylori-specific immunoglobulin G antibody titers were measured by ELISA. CKD was defined as estimated glomerular filtration rate (eGFR) less than <60 ml/min/1.73 m2 or presence of proteinuria (urine protein ≥ 1+) assessed using a repeated dipstick method. RESULTS Among all participants in this study, the prevalence of H. Pylori infection was 20.6%. As a categorical outcome, the prevalence of decreased eGFR in the H. Pylori infection group was higher than in the non-H. Pylori infection group (1.6 vs. 1.2%, P = 0.04), but the prevalence of proteinuria and the overall CKD were not significantly different between these two groups (1.7 vs. 1.6%, P = 0.65 and 3.0 vs. 2.7%, P = 0.2). After adjusted for age, sex, hypertension, diabetes, body mass index, uric acid, smoking, drinking, total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, the odds of decreased eGFR and proteinuria were not significantly different between the H. Pylori positive and negative subjects. CONCLUSIONS This study did not find an association between H. Pylori infection and CKD.

Abstract
Increasing evidences have shown that Helicobacter pylori (Hp) is a pathogen closely related to extra-gastric disorders. Our previous in vitro studies had demonstrated that Hp infection, at least via cytotoxin-associated gene A protein (CagA), might play an important role in the pathogenesis of IgA nephropathy (IgAN) by stimulating proliferation and ectopic synthesis of aberrantly glycosylated IgA1 of B cells. However, the relevant clinical evidence of IgAN resulted from Hp infection remain to be elucidated. This study aimed to investigate the risk incidence of IgAN caused by Hp infection. 22 primary IgAN, 20 non-IgA nephropathy (n-IgAN), and 30 healthy controls were included in this study. We found that the rate of IgG anti-Hp seropositivity was significantly improved in IgAN, but the current Hp infection was similar in all groups. The production and underglycosylation of IgA1 tended to increase in IgAN patients with IgG anti-Hp seropositivity. A tendency toward increased the risk of clinical prognosis was seen in IgAN with Hp infection. Hp antigen and CagA were only deposited in renal tubules, and enhanced antigen deposition in response to Hp was observed in IgAN. Our study suggested that Hp infection might have a pathogenic role in IgAN through giving rise to strongly mucosal immune response, and based on damage of renal tubular.

OPHTHALMOLOGY AND EYE DISEASES 2016; 8:1-4. [PMID: 26917977 PMCID: PMC4758802 DOI: 10.4137/oed.s35895] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Revised: 12/03/2015] [Accepted: 12/04/2015] [Indexed: 12/20/2022]
Abstract
INTRODUCTION Glaucoma is a public health issue worldwide, particularly in Africa. In Cameroon, the prevalence rate of primary open-angle glaucoma (POAG) ranges between 4.5% and 8.2%. Helicobacter pylori (HP) has been implicated in digestive and extra-digestive diseases, including glaucoma. The objective of this work was to evaluate the implication of CagA- and VacA-positive strains of HP in POAG using a case-control design. METHODS An analytical study was conducted from October 2013 to December 2013. Participants were recruited in eye care centers in Yaoundé. Enzyme-linked immunosorbent assays (ELISAs) were carried out in the La Grace Laboratory in Yaoundé. RESULTS The total sample consisted of 50 POAG patients and 31 controls with a mean age of 58.5 ± 12.2 years and 45.5 ± 14.6 years, respectively. The prevalence rates of HP in the POAG and control groups were 74% (37/50) and 87% (27/31), respectively (P = 0.125). The prevalence rates of CagA-positive HP seropositivity in the POAG and control groups were 26% and 22.58%, respectively (P = 0.47), and the prevalence rates of VacA-positive HP participants were 6% and 0%, respectively (P = 0.22). CONCLUSION The HP prevalence rates among POAG patients and controls were 74% and 87%, respectively. There was no significant difference between prevalence rates of HP in the POAG and control groups. There was no association between POAG and CagA- or VacA-positive HP infection.

Increased risk of chronic obstructive pulmonary disease among patients with Helicobacter pylori infection: a population-based cohort study. CLINICAL RESPIRATORY JOURNAL 2015; 11:558-565. [PMID: 26364850 DOI: 10.1111/crj.12382] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 04/21/2015] [Revised: 08/10/2015] [Accepted: 09/06/2015] [Indexed: 01/01/2023]
Abstract
BACKGROUND Increasing evidence suggests that Helicobacter pylori infection (HPI) may have extragastric manifestations, including the respiratory system. This study investigated the role of HPI in increasing the subsequent risk of chronic obstructive pulmonary disease (COPD) in a nationwide population. METHODS We conducted this retrospective cohort study using data from the Longitudinal Health Insurance Database, which is derived from the Taiwanese National Health Insurance Research Database. A total of 5941 adults who were newly diagnosed with HPI between 2005 and 2006 were selected. Healthy patients without HPI were selected from the general population and frequency matched as a ratio of 4:1, according to age, sex, and index years. Both cohorts were followed up from the index date to the end of 2011 to measure the incidence of COPD. Cox proportional hazard regression analysis was used to assess the hazard ratio (HR) of COPD between the HPI cohort and non-HPI cohorts. RESULTS The overall HR of COPD was 1.84 (95% confidence intervals = 1.57-2.17) for the HPI cohort, compared with the non-HPI cohort, after adjusting for age, sex, and comorbidities. Although the incidence of COPD was substantially higher in the elderly participants (age, ≥ 65 years) than that in younger participants, the highest HR (4.05, 95% confidence intervals = 1.39-11.8) of COPD was observed in the youngest (age, 20-49 years) participants. CONCLUSION In this study, the patients with HPI exhibited a significantly higher risk of COPD than those without HPI did.

Abstract
BACKGROUND Epidemiological studies have indicated that patients with chronic Helicobacter pylori infection have an increased risk of developing type 2 diabetes mellitus, but the underlying mechanisms remain largely unknown. This study aimed to investigate whether H. pylori infection contributes to the development of insulin resistance, as well as the underlying mechanisms both in vivo and in vitro. METHODS The effect of H. pylori infection on glucose metabolism was evaluated in humans and mouse models. The role of the c-Jun/miR-203/suppressor of cytokine signaling 3 (SOCS3) pathway in H. pylori-induced insulin resistance was determined in vitro and was validated in vivo. RESULTS Average fasting glucose levels were increased in patients (P = 0.012) and mice (P = 0.004) with H. pylori infection. Diabetic mice with H. pylori infection showed impaired glucose metabolism and insulin tolerance and hyperinsulinemia. Furthermore, H. pylori infection impaired insulin signaling in primary hepatocytes. H. pylori infection could upregulate SOCS3, a well-known insulin signaling inhibitor, by downregulating miR-203. SOCS3 overexpression interfered with insulin signaling proteins, and knockdown of SOCS3 alleviated H. pylori-induced impairment of insulin signaling. The transcription factor c-Jun, which affects gene expression, was induced by H. pylori infection and suppressed miR-203 expression. CONCLUSIONS Our results demonstrated that H. pylori infection induced hepatic insulin resistance by the c-Jun/miR-203/SOCS3 signaling pathway and provide possible implications with regard to resolving insulin resistance.

Abstract
Throughout the history of mankind, infections have been the major cause of diseases. Over the last decades, not only the incidence of emerging infectious diseases have increased, but also tremendous strides have been made in understanding the biology of several pathogenic microorganisms. Helicobacter pylori (H. pylori) is a spiral-shaped, gram-negative bacterium, which infects over the half of the world’s population. H. pylori has been implicated in the pathogenesis of a number of gastrointestinal disorders. However, new researches have demonstrated that H. pylori is also involved in the pathogenesis of various extragastric diseases. The difference in the clinical outcome of H. pylori infection may be explained, at least in part, by host response to the infection and H. pylori virulence factors. It is obvious that as developments in the research on H. pylori spring up, an understanding of the pathophysiology of H. pylori infection will continue to be identified. Here in this review, we summarize the current knowledge about H. pylori and its association with inflammatory skin diseases.

Abstract
Animal Helicobacter species other than Helicobacter pylori are also able to cause human gastritis, gastric ulcers, and MALT lymphomas. Animal Helicobacter species are presented with typical spiral fastidious microorganisms colonizing the gastric mucosa of different animals. Bacteria initially received their provisional name Helicobacter heilmannii, and out of them at least five species colonizing the gastric mucosa of pigs, cats, and dogs were isolated later on. A high proportion of these diseases are shown to be zoonotic. Transmission of pathogens occurs by contact. The factors of bacterial pathogenicity remain little studied.

Abstract
UNLABELLED The link between Helicobacter pylori and iron deficiency (ID) or iron deficiency anemia (IDA) has been investigated recently. We suggested that IDA/ID associated with H. pylori infection might be mediated by inflammation-driven hepcidin production. Patients with complaints of recurrent abdominal pain and dyspepsia aged between 7-16 years were included in this study. Patients were divided into two groups according to H. pylori status in upper gastrointestinal endoscopy. Group I who had H. pylori gastritis (n=50) received triple antibiotic therapy. Group II (n=50) who had H. pylori-negative gastritis only received proton pump inhibitor. Thirty healthy children with the similar age and gender were included in the study as a control group. Complete blood count, serum iron levels, iron-binding capacity, ferritin levels, prohepcidin and interleukin-6 (IL-6) values were evaluated in all children at the first visit. Initial tests were repeated after H. pylori eradication. Initial levels of ferritin (p=0.002), prohepcidin (p=0.003), and IL-6 (p=0.004) were found significantly lower in group I compared to group II and the control group. The mean prohepcidin level was lower in the anemic H. pylori-positive group than in non-anemic H. pylori-positive group; however, the difference was not statistically significant. While significant increases in hematocrit and mean corpuscular volume were observed, no significant difference was found in serum ferritin, prohepcidin, or IL-6 level after eradication treatment in H. pylori-positive group. CONCLUSION H. pylori-induced gastritis appears to cause an increase in prohepcidin levels and a decrease in ferritin levels, supporting our hypothesis; but this relationship has not been proven.

Abstract
BACKGROUND Epidemiological studies have demonstrated the relationship between Helicobacter pylori infection and gastric and extra-gastric diseases. Therefore, H. pylori infection might be a "systemic" disease. AIM To investigate the relationship between H. pylori infection status and serum parameter levels responding to multi-organ functions. METHODS A total of 2,044 subjects were selected, including 1,249 males and 795 females with ages ranging from 16 to 86 years. Relevant parameters including blood lipids, complete blood count, tumor markers, indexes of stomach, kidney, liver, thyroid, and immune system function, H.pylori IgG antibody levels, and (14)C-UBT were collected. RESULTS Serum pepsinogen (PG)I, PGII, and gastrin (G)17 levels were decreased in chronic long-term, past, and acute short-term infection patients compared with uninfected controls. However, the serum PGI/II ratio increased gradually. Serum white blood cell levels gradually decreased in past, chronic long-term, and acute short-term infection patients compared with uninfected controls. The same trend was also observed for CD4(+) T cell levels. In addition, LDL levels were higher in chronic long-term infection, HDL levels were lower in past infection, and ALP and CEA levels were higher in acute short-term infection compared with the uninfected group. CONCLUSIONS Helicobacter pylori infection correlated with increased PGI, PGII, G17, WBC, and CD4(+) T cell levels, and decreased PGI/II ratio. In chronic long-term or past infection, H. pylori infection was associated with higher LDL or lower HDL levels. In acute short-term infection, H. pylori infection correlated with higher ALP and CEA levels. H. pylori infection correlated with serum parameter levels responding to multi-organ functions.

Abstract
BACKGROUND Data from the literature concerning the role of Helicobacter pylori (H. pylori) infection in psoriasis are still conflicting. This study was carried out to evaluate prevalence of H. pylori in patients with mild to severe psoriasis, correlation between H. pylori infection and severity of psoriasis, and effect of H. pylori eradication on the clinical course of psoriasis. METHODS Two hundred and ten patients with psoriasis and 150 healthy controls were screened for H. pylori through [(13) C] urea breath test at baseline (T0). All patients with psoriasis received standardized phototherapy treatment, and those infected by H. pylori were also treated with a 1-week triple therapy, then they were all re-evaluated four weeks later at the end of therapy (T5). RESULTS The prevalence of H. pylori was not higher in psoriasis than in the control group (20.27 vs. 22%; P > 0.05). Patients infected by H. pylori showed more severe psoriasis than uninfected patients (psoriasis area and severity index score 17.9 ± 7.1 vs. 13.7 ± 6.9; P = 0.04), and patients who received successful eradication of H. pylori infection showed a greater improvement of psoriasis than the others (psoriasis area and severity index score at T5 in patients infected by H. pylori was 8.36 ± 3.76, in uninfected patients was 10.85 ± 3.49; P = 0.006). CONCLUSIONS Patients with mild to severe psoriasis do not show a greater prevalence of H. pylori infection; however, H. pylori seems able to affect the clinical severity of psoriasis.

Abstract
At present, the clinical significance of Helicobacter pylori infection has been validly determined within the development of a diversity of gastroduodenal diseases, including chronic gastritis, gastroduodenal ulcer, MALT lymphoma, and gastric adenocarcinoma. The Expert Council's Maastricht IV consensus (2010) determining international standards for the diagnosis and treatment of H. pylori infection is that there is evidence that the latter may be associated with the development of a number of extragastroduodenal diseases (EGDDs) presented by iron-deficiency anemia of unspecified etiology, idiopathic thrombocytopenic purpura, and vitamin B12 deficiency. In these diseases, it is recommended that infection with H. pylori be diagnosed and, if the test is positive, this microorganism be eradicated. A large number of investigations have been recently conducted to examine the association of H. pylori infection with other EGDDs. This paper reviews theoretical and epidemiological data on the association of H. pylori with diseases of the cardiovascular (atherosclerosis, myocardial infarction) and central nervous (Alzheimer's disease, Parkinson's disease) systems, pancreas (autoimmune pancreatitis, pancreatic cancer), oncological (colonic adenomas, colorectal cancer, hepatocellular carcinoma), dermatological (chronic spontaneous urticaria), and other EGDDs. The review highlights the potential protective role of H. pylori in diseases with the atopic element of genesis and a complicated course of gastroesophageal reflux disease (Barrett's esophagus, esophageal adenocarcinoma).

Abstract
UNLABELLED Helicobacter have been detected in human bile and hepatobiliary tissue. Despite evidence that Helicobacter species promote gallstone formation and hepatobiliary tumors in laboratory studies, it remains unclear whether Helicobacter species contribute to these cancers in humans. We used a multiplex panel to assess whether seropositivity to 15 Helicobacter pylori proteins was associated with subsequent incidence of hepatobiliary cancers in the Finnish Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study. We included 64 biliary cancers, 122 liver cancers, and 224 age-matched controls which occurred over the course of 22 years. Helicobacter pylori seropositivity was defined as those positive to ≥ 4 antigens. Odds ratios (OR) and 95% confidence intervals were adjusted for major hepatobiliary cancer risk factors. Among the controls, 88% were seropositive to H. pylori at baseline. Among those who subsequently developed hepatobiliary cancer, the prevalence of seropositivity was higher: 100% for gallbladder cancer, 97% of extrahepatic bile duct cancer, 91% of ampula of Vater cancer, 96% of intrahepatic bile duct cancer, and 94% of hepatocellular carcinoma. Although the OR for gallbladder cancer could not be calculated, the OR for the other sites were 7.01 (95% confidence interval [CI]: 0.79-62.33), 2.21 (0.19-25.52), 10.67 (0.76-150.08), and 1.20 (0.42-3.45), respectively, with an OR of 5.47 (95% CI: 1.17-25.65) observed for the biliary tract cancers combined. ORs above 1 were observed for many of the investigated antigens, although most of these associations were not statistically significant. CONCLUSION Seropositivity to H. pylori proteins was associated with an increased risk of biliary tract cancers in ATBC. Further studies are needed to confirm our findings and to determine how H. pylori might influence the risk of biliary tract cancer.

Abstract
The isolation of Helicobacter pylori from the human stomach produced significant changes in how gastroenterologists, immunologists, epidemiologists, pathologists and microbiologists have approached gastro-duodenal diseases in the last half of the XX century. However, research of this organism has progressed greatly in the first decade of this century, evidence suggest that H. pylori is associated with disease only in humans older than 40 years, while, the lack of H. pylori colonization is associated with the emergence of new diseases, particularly in younger individuals. These differing effects of H. pylori colonization have created two contrasting concepts: the 'bad' and the 'good' Helicobacter. Following from renewed interest in the normal human microbiome, we need to reconsider our definitions and perhaps recognize that H. pylori might be a normal member of the human gastric microbiome in ancient humans that gradually, as results of the improvement in our environment, is disappearing.

Abstract
Helicobacter pylori (H. pylori) is the most common infection in humans, with a marked disparity between developed and developing countries. Although H. pylori infections are asymptomatic in most infected individuals, they are intimately related to malignant gastric conditions such as gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and to benign diseases such as gastritis and duodenal and gastric peptic ulcers. Since it was learned that bacteria could colonize the gastric mucosa, there have been reports in the medical literature of over 50 extragastric manifestations involving a variety medical areas of specialization. These areas include cardiology, dermatology, endocrinology, gynecology and obstetrics, hematology, pneumology, odontology, ophthalmology, otorhinolaryngology and pediatrics, and they encompass conditions with a range of clear evidence between the H. pylori infection and development of the disease. This literature review covers extragastric manifestations of H. pylori infection in the hematology field. It focuses on conditions that are included in international consensus and management guides for H. pylori infection, specifically iron deficiency, vitamin B12 (cobalamin) deficiency, immune thrombocytopenia, and MALT lymphoma. In addition, there is discussion of other conditions that are not included in international consensus and management guides on H. pylori, including auto-immune neutropenia, antiphospholipid syndrome, plasma cell dyscrasias, and other hematologic diseases.

Abstract
Context Limited clinical data suggest Helicobacter pylori (Hp) infection may contribute to nonalcoholic fatty liver disease (NAFLD) pathogenesis. Objectives The effect of Hp eradication on hepatic steatosis (magnetic resonance imaging), nonalcoholic fatty liver disease fibrosis score and HSENSI (Homocysteine, serum glutamic oxaloacetic transaminase, Erythrocyte sedimentation rate, nonalcoholic steatohepatitis Index) in nonalcoholic steatohepatitis patients. Methods Thirteen adult patients with biopsy-proven nonalcoholic steatohepatitis, asymptomatic for gastrointestinal disease, underwent 13C urea breath test; Hp positive patients received eradication therapy until repeat test become negative. Hepatic fat fraction, standard biochemical tests and calculation of nonalcoholic fatty liver disease fibrosis score and HSENSI were performed at baseline and month 12. Results Hepatic fat fraction was similar for between and within group comparisons. Nonalcoholic fatty liver disease fibrosis score showed a non-significant trend towards decrease in Hp(+) [-0.34 (-1.39-0.29) at baseline and -0.24 (-0.99-0.71) at month 12; P = 0.116], whereas increase in Hp(-) group [-0.38 (-1.72-0.11) and -0.56 (-1.43-0.46), respectively; P = 0.249]. HSENSI was significantly decreased only in Hp(+) group [1.0 (1.0-2.0) at baseline and 1.0 (0-1.0) at month 12; P = 0.048]. Conclusions Hp eradication had no long-term effect on hepatic steatosis, but showed a trend towards improvement in nonalcoholic fatty liver disease fibrosis score and HSENSI. These results warrant larger studies with paired biopsies.

Abstract
While Helicobacter pylori infection was initially revealed to be associated only with some gastroduodenal diseases, further studies have shown its possible role in several extragastric diseases. For idiopathic thrombocytopenic purpura, sideropenic anemia, and vitamin B12 deficiency, the diagnosis of H. pylori infection is recommended, and there are many other conditions such as cardiovascular, neurological, dermatological, and respiratory diseases in which H. pylori may possibly play a role. Interestingly, a potential role has also been described for GI neoplastic diseases, including colorectal and pancreatic cancer. Different mechanisms of action have been proposed, ranging from the induction of a low grade inflammatory state to the occurrence of molecular mimicry mechanisms. This review summarizes the results of the most relevant studies published on this topic over the last year.

Abstract
Background. Helicobacter pylori (H. pylori) was linked with several extragastrointestinal diseases, including preeclampsia and intrauterine growth restriction of fetus. One of the signals which can be transferred from mother to fetus is the H. pylori IgG antibody. Aims. We utilized a commercial immunochromatographic kit to detect the antibody in maternal and cord serum. Methods. Three hundred and forty-six females were enrolled and the blood samples were collected on antenatal examination and on delivery. The maternal H. pylori infection was determined by stool H. pylori antigen test. Results. One hundred and five females (30.3%) were H. pylori-infected, and the prevalence was higher in immigrants (43.5%) than in Taiwanese (28.7%, P = 0.058). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the kit were 77.1%, 88.0%, 73.6%, 89.8%, and 84.7%, respectively. This kit also had similar performance in cord serum. Comparing to the maternal result on delivery, this kit offered a consistent performance in antenatal maternal serum (kappa coefficient 0.92) and in cord serum (kappa coefficient 0.88). Conclusions. H. pylori IgG antibody can be transferred through the placenta into the fetal circulation. However, accuracy of the test kit needs to be evaluated before utilization in screening.

Abstract
Eradication of Helicobacter pylori should not be avoided because of complicated reflux symptoms. Previously, although H. pylori eradication in patients with GORD was considered to induce unfavourable effects that worsen reflux symptoms, recent reports indicates that it can have favourable consequences by reducing symptoms and therefore improving quality of life, especially in GORD patients without severe corpus atrophy or severe hiatal herniation.

Abstract
Helicobacter pylori (H. pylori) infects more than half of the world’s human population, but only 1% to 3% of infected people consequently develop gastric adenocarcinomas. The clinical outcome of the infection is determined by host genetic predisposition, bacterial virulence factors, and environmental factors. The association between H. pylori infection and chronic active gastritis, peptic ulcer disease, gastric cell carcinoma, and B cell mucosa-associated lymphoid tissue lymphoma has been well established. With the exception of unexplained iron deficiency anemia and idiopathic thrombocytopenic purpura, H. pylori infection has no proven role in extraintestinal diseases. On the other hand, there is data showing that H. pylori infection could be beneficial for some human diseases. The unpredictability of the long-term consequences of H. pylori infection and the economic challenge in eradicating it is why identification of high-risk individuals is crucial.

Abstract
BACKGROUND Evidence has shown an association of Helicobacter pylori infection with liver dysfunction and damage. We investigated if H. pylori eradication affects liver enzymes in patients referring with unexplained hypertransaminasemia. MATERIALS AND METHODS Patients with mild unexplained hypertransaminasemia accompanied with dyspepsia and confirmed H. pylori infection were studied. Viral, metabolic, autoimmune, and drug/toxin induced hepatitis as well as fatty liver were all ruled-out by appropriate tests. Patients received bismuth-containing quadruple-therapy for 2 weeks. Serum levels of liver enzymes (alanine transaminase (ALT) and aspartate transaminase (AST)) and successful eradication (with stool antigen test) were evaluated 4 weeks after the medication. RESULTS A total number of 107 patients (55 males, mean age = 35.0 ± 8.4 years) were studied. Eradication was successful in 93 patients (86.9%). Serum levels of AST (6.3 ± 19.6 IU/L, P = 0.002) and ALT (7.8 ± 24.9 IU/L, P = 0.001) were significantly decreased after eradication. Levels of AST and ALT decreased to normal range respectively in 46.6% and 45.7% of the cases who had baseline levels above the normal range. CONCLUSION This study showed a decrease in liver enzymes after receiving eradication regimen of H. pylori, suggesting a role for H. pylori infection in at least some of patients with mild unexplained hypertransaminasemia. Further studies are warranted to find the underlying mechanisms by which H. pylori infection affects the liver and clinical importance of such effects.

Abstract
BACKGROUND Many consider histology to be the gold standard for Helicobacter pylori detection. Because the number and distribution of H pylori organisms vary, particularly in patients taking proton pump inhibitors (PPIs), the American Gastroenterological Association recommends discontinuing PPIs two weeks before endoscopy, and taking biopsies from both the body and antrum. OBJECTIVE To assess the influence of clinical practice on the histopathological detection of H pylori infection. METHODS Electronic patient records were evaluated for the sites of gastric sampling and PPI use at endoscopy. One hundred fifty cases with biopsies taken from both antrum and body were randomly selected for pathological re-review with special stains. The gastric regions sampled, H pylori distribution and influence of clinical factors on pathological interpretation were assessed. RESULTS Between 2005 and 2010, 10,268 biopsies were taken to detect H pylori. Only one region was sampled in 60% of patients (antrum 47%, body 13%). Re-review of biopsies taken from both antrum and body indicated that the correct regions were sampled in only 85 (57%) patients. Of these, 54 were H pylori positive and 96 were H pylori negative. H pylori was present in the antrum in only 15% of the patients and body only in 21%. Of 96 H pylori-negative patients, two were reinterpreted as positive. Forty-seven per cent of patients were taking PPIs at endoscopy, contributing to both false-negative and false-positive diagnoses. CONCLUSION Despite national and international guidelines for managing H pylori infection, the American Gastroenterological Association guidelines are infrequently adhered to, with PPIs frequently contributing to false diagnosis; sampling one region only increases the likelihood of missing active infection by at least 15%.

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 Helicobacter pylori (HP) infection is the most common infection in the world and coronary artery disease (CAD) is probably associated with it. The aim of this prospective study was to evaluate the association between HP infection and CAD in suspected patients referred for coronary angiography. The coronary angiography was performed using Judkins method and patients were assigned to participate in CAD positive (>50% luminal diameter stenosis) and negative groups. The serum HP IgG antibody was checked. RESULTS Positive and negative CAD groups consisted of 62 and 58 patients, respectively. HP was more prevalent among CAD+ patients, and with increasing the number of coronary arteries with stenosis, the HP seropositivity increased so that 76.3% of patients with multiple vessel diseases (MVD) and 70% of patients with single vessel diseases (SVD) were HP seropositive versus 50% in control group (P = 0.006). Positive CAD was significantly associated with HDL level (P = 0.01) and ESR level (P = 0.006). Also, CAD+ patients had higher CRP levels than controls and it was statistically different between SVD group and controls (P < 0.05). CONCLUSION HP infection is more prevalent in CAD positive patients and, in case of proving causal relationship, it can be considered as a reversible risk factor for CAD.

Abstract
Background The epidemiology of Helicobacter pylori infection in inmates has not been previously studied. Therefore, we determine the seroepidemiology of H. pylori infection in inmates. Methods Through a case-control study, inmates from a state correctional facility in Durango, Mexico and subjects without incarceration of the same city were examined for the presence of anti-H. pylori IgG antibodies using enzyme-linked immunoassays. Seroprevalence association with socio-demographic, incarceration, clinical and behavioral characteristics of the inmates was also investigated. Results Antibodies to H. pylori were found in 140 (83.3%) of 168 inmates and in 101 (60.1%) of 168 controls. Seroprevalence of anti-H. pylori IgG antibodies was significantly higher in inmates than in controls (OR = 3.32; 95% CI: 1.93 - 5.71; P = 0.000002). The seroprevalence of H. pylori infection was not influenced by gender, age, or socioeconomic status of inmates. Seropositivity to H. pylori was found in 3 of 3 inmates with peptic ulcer and in 1 of 2 inmates with gastritis. The seroprevalence of H. pylori exposure was high regardless the jail section, duration (years) in incarceration and number of incarcerations. Multivariate analysis revealed that H. pylori exposure was positively associated with having tattoos (OR = 3.34; 95% CI: 1.14 - 9.70; P = 0.02), and negatively associated with drug abuse (OR = 0.28; 95% CI: 0.11 - 0.70; P = 0.007). Conclusions Seroprevalence of H. pylori exposure in inmates is higher than those found in non-incarcerated people and other populations in the region. Results indicate that inmates may represent a new risk group for H. pylori exposure. Results warrant for further research on the potential role of incarceration and behavioral features of inmates for H. pylori infection.

Abstract
Thirty years have passed since Warren and Marshall's discovery of Helicobacter pylori (H. pylori). Since then, not only peptic ulcer diseases and chronic gastritis but also non-cardia gastric cancers have been recognized as diseases originating from H. pylori infection. Several combination therapies consisting of multiple antibiotics have been developed as first- or second-line regimens to eradicate H. pylori infection. Our extensive experience in the field of anti-H. pylori medicine suggests that clinicians should consider a possible role for unidentified, invisible pathogens to elucidate the pathogenesis and improve the treatment of refractory diseases of unknown etiology.

Abstract
BACKGROUND Helicobacter pylori infection is a major risk factor for chronic gastritis, digestive ulcers, and gastric cancer. Previous studies have shown associations between H. pylori infection and decreased iron storage. Therefore, this study aimed to examine the associations between H. pylori infection and serum iron and ferritin levels in Japan. MATERIALS AND METHODS Overall, 268 Japanese individuals who visited a clinic located in an urban area for H. pylori infection tests and subsequent eradication were enrolled. H. pylori infection was diagnosed by a (13) C-urea breath test, with positive results defined as values ≥2.5‰. RESULTS The overall infection rate was 65.3% (175/268). The geometric mean serum iron levels in uninfected and infected subjects were 115.7 μg/dL and 108.9 μg/dL, respectively, in men, and 83.9 and 91.8 μg/dL, respectively, in women. The geometric mean serum ferritin levels were 128.9 and 81.0 ng/mL, respectively, in men, and 25.5 and 27.0 ng/mL, respectively, in women. Regression analysis adjusted for age showed that lower geometric mean serum ferritin levels were significantly associated with H. pylori infection in men (131.8 vs 79.4 ng/mL p = .009) and in women (33.9 vs 23.4 ng/mL p = .041). The difference was greater in subjects ≥50 years old, although the interaction was not statistically significant. Helicobacter pylori infection was not significantly associated with serum iron levels. CONCLUSION This study showed that H. pylori infection was significantly associated with altered serum ferritin levels in Japanese individuals, particularly in those aged ≥50 years.

Abstract
BACKGROUND AND AIMS Diabetic patients reportedly have a higher incidence of peptic ulcer disease. The aim of this study was to investigate if type II diabetic patients have higher risk of developing peptic ulcer bleeding (PUB) and to identify possible risk factors of PUB in diabetic patients. METHODS Using the National Health Insurance Research Database of Taiwan, records of 5699 type II diabetic patients and 11,226 age- and sex-matched non-diabetic patients in a 1:2 ratio were extracted for comparison from a cohort dataset of 1,000,000 randomly sampled subjects. Log-rank test was used to analyze differences in cumulative hazard of PUB between the two groups. Cox proportional hazard regressions were used to evaluate independent risk factors for PUB in all patients and identified risk factors of PUB in type II diabetic patients. RESULTS In a 7-year follow-up period, type II diabetic patients had significantly higher cumulative hazard of PUB than the controls (P < 0.001, log-rank test). By Cox proportional hazard regression analysis, diabetes was independently associated with increased risk of PUB (hazard ratio 1.44, 95% confidence interval 1.11-1.86; P < 0.001) after adjusting for age, sex, comorbidities (e.g. hypertension, coronary heart disease, heart failure, chronic renal disease, cirrhosis, and peptic ulcer disease), and ulcerogenic medication. Age, chronic renal disease, history of peptic ulcer disease, and use of non-steroidal anti-inflammatory drugs were risk factors for PUB in diabetic patients. CONCLUSIONS Type II diabetic patients have significantly higher risk of PUB even after adjustments for possible confounding factors like age, sex, underlying comorbidities, and ulcerogenic medication.

Abstract
The destruction of the integrity of the gastric epithelial barrier underlies the pathology of many gastric diseases, including gastric tumors. The Helicobacter pylori virulence factor CagA is one of the main destroyers of the gastric epithelial barrier. There are differences among CagA proteins that originate from different isolates. CagA translocated into the gastric epithelial cells causes significant changes in cell signaling pathways in phosphorylation-dependent and phosphorylation-independent manners, leading to cell morphological changes and host cell epithelial barrier injury, which lay the foundation for the occurrence of related diseases. As a newly identified pathogenic mechanism of CagA, miRNA is involved in the remodeling of the gastric epithelial barrier. Both the eradication of H. pylori infection and interventions against CagA-induced gastric epithelial barrier lesions may contribute to the prevention of the development of gastric tumors.

Abstract
Helicobacter pylori (Hp) is one of the most common bacteria infecting humans. Recently, certain extragastric manifestations, linked to Hp infection, have been widely investigated, suggesting that Hp infection might be a 'systemic' disease. Accumulating, yet limited, evidence points to a potential association between Hp infection and lung cancer risk. Epidemiologic studies have shown that odds ratios (estimated relative risks) of lung cancer with Hp infection range from 1.24 to 17.78 compared with the controls, suggesting an increased lung cancer risk in the population exposed to Hp infection although far from supporting a causal relationship between Hp and lung cancer. Many studies have demonstrated the existence of Hp in the mucosa of the upper respiratory tract with no direct evidence of Hp-localization in lung tissue in the published literatures, rendering the possible functional mechanism underlying the association an open question. We followed the classic hypothesis-generating path, where we have thoroughly reviewed the publications on lung cancer and Hp infection from serological association to possible mechanisms as: (i) p130cas activated by Src kinase following Hp-host communication and p130cas-related carcinogenesis as in various malignancies; and (ii) gastroesophageal reflux and inhalation of urease or gastrin, which are Hp-related carcinogenic factors and present in lung tissues. We propose rigorous investigations regarding the Hp-lung cancer association and, if confirmed, the mechanisms of Hp infection leading to lung cancer development and progression. Clarification on Hp-lung cancer association is important for the understanding of lung cancer beyond tobacco-smoking-related carcinogenesis.
