Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.
A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).
Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
A semisynthetic macrolide antibiotic derived from ERYTHROMYCIN that is active against a variety of microorganisms. It can inhibit PROTEIN SYNTHESIS in BACTERIA by reversibly binding to the 50S ribosomal subunits. This inhibits the translocation of aminoacyl transfer-RNA and prevents peptide chain elongation.
A nitroimidazole used to treat AMEBIASIS; VAGINITIS; TRICHOMONAS INFECTIONS; GIARDIASIS; ANAEROBIC BACTERIA; and TREPONEMAL INFECTIONS. It has also been proposed as a radiation sensitizer for hypoxic cells. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985, p133), this substance may reasonably be anticipated to be a carcinogen (Merck, 11th ed).

The significance of cagA and vacA subtypes of Helicobacter pylori in the pathogenesis of inflammation and peptic ulceration. (1/5095)AIMS: To assess the significance of cagA and vacA subtypes of Helicobacter pylori in relation to inflammation and density of bacterial colonisation in vivo within a dyspeptic UK population. METHODS: Dyspeptic patients who were Helicobacter pylori positive had antral samples taken for histology and culture. Gastroduodenal pathology was noted. The grade of bacterial density and inflammation was assessed using the Sydney system. Bacterial DNA was extracted and the vacA alleles and the cagA/gene typed using PCR. RESULTS: 120 patients were studied. There was high rate of cagA positive strains in this population. Bacterial density did not correlate with the presence of peptic ulceration. There was a significant association between cagA positive strains and increased inflammation and bacterial density. The vacA s1 type independently correlated with extensive chronic inflammation but there was no association with bacterial density. The vacA m type did not correlate with extent of inflammation or bacterial density. CONCLUSIONS: The results suggest that cagA is important in the pathogenesis of inflammation and peptic ulceration. These findings are in keeping with the hypothesis that cagA acts as a marker for a cag pathogenicity island which encodes several genes involved in inflammation. The vacA s1 allele correlates with inflammation independently of cagA, possibly through its enhanced ability to produce the vacuolating cytotoxin. (+info)
Chemokine mRNA expression in gastric mucosa is associated with Helicobacter pylori cagA positivity and severity of gastritis. (2/5095)AIM: To investigate the association between the quantity of gastric chemokine mRNA expression, severity of gastritis, and cagA positivity in Helicobacter pylori associated gastritis. METHODS: In 83 dyspeptic patients, antral and corpus biopsies were taken for semiquantitative reverse transcription polymerase chain reaction (RT-PCR) and histological grading of gastritis. Gastritis was evaluated by visual analogue scales. Quantities of chemokine (IL-8, GRO alpha, ENA-78, RANTES, MCP-1) RT-PCR products were compared with G3PDH products. Each sample was also evaluated for the presence of cagA and ureA mRNA by RT-PCR. RESULTS: mRNA expression of all five chemokines was significantly greater in H pylori positive than in H pylori negative mucosa. In H pylori positive patients, in the antrum C-X-C chemokine mRNA expression was significantly greater in cagA positive patients than in cagA negative patients, but there were no significant differences in C-C chemokine mRNA expression. In H pylori positive patients, chemokine mRNA expression in the corpus was less than in the antrum. In contrast to the antrum, only GRO alpha mRNA expression was significantly greater in cagA positive infection. Polymorphonuclear cell infiltration was correlated with C-X-C chemokine mRNA expression. Significant correlations were also found between bacterial density and C-X-C chemokine mRNA expression. CONCLUSIONS: In H pylori infection, C-X-C chemokines may play a primary role in active gastritis. Infection with cagA positive H pylori induces greater gastric chemokine mRNA expression in the antral mucosa, which may be relevant to the increased mucosal damage associated with cagA positive H pylori infection.

Helicobacter pylori infection, garlic intake and precancerous lesions in a Chinese population at low risk of gastric cancer. (3/5095)BACKGROUND: Cangshan County of Shandong Province has one of the lowest rates of gastric cancer (GC) in China. While intestinal metaplasia (IM) and dysplasia (DYS) are less common in Cangshan than in areas of Shandong at high risk of GC, these precursor lesions nevertheless affect about 20% of adults age > or = 55. SUBJECTS AND SETTING: In order to evaluate determinants of IM and DYS in Cangshan County, a low risk area of GC a survey was conducted among 214 adults who participated in a gastroscopic screening survey in Cangshan County in 1994. METHOD: A dietary interview and measurement of serum Helicobacter pylori antibodies were performed. RESULTS: The prevalence of H. pylori was lowest (19%) among those with normal gastric mucosa, rising steadily to 35% for superficial gastritis (SG), 56% for chronic atrophic gastritis (CAG), 80% for IM, and 100% for DYS. The prevalence odds of precancerous lesions were compared with the odds of normal histology or SG. The odds ratio (OR) or CAG associated with H. pylori positivity was 4.2 (95% confidence interval [CI] : 1.7-10.0), while the OR of IM/DYS associated with H. pylori positivity was 31.5 (95% CI: 5.2-187). After adjusting for H. pylori infection, drinking alcohol was a risk factor for CAG (OR = 3.2, 95% CI: 1.1-9.2) and IM/DYS (OR = 7.8, 95% CI: 1.3-47.7). On the other hand, consumption of garlic showed non-significant protective effects and an inverse association with H. pylori infection. CONCLUSIONS: The findings of this study suggest that infection with H. pylori is a risk factor and garlic may be protective, in the development and progression of advanced precancerous gastric lesions in an area of China at relatively low risk of GC.

Chronic infection with Helicobacter pylori, Chlamydia pneumoniae, or cytomegalovirus: population based study of coronary heart disease. (4/5095)OBJECTIVE: To study possible associations between coronary heart disease and serological evidence of persistent infection with Helicobacter pylori, Chlamydia pneumoniae, or cytomegalovirus. DESIGN: Population based, case-control study, nested within a randomised trial. SETTING: Five general practices in Bedfordshire, UK. INDIVIDUALS: 288 patients with incident or prevalent coronary heart disease and 704 age and sex matched controls. RESULTS: High concentrations of serum IgG antibodies to H pylori were present in 54% of cases v 46% of controls, with corresponding results for C pneumoniae seropositivity (33% v 33%), and cytomegalovirus seropositivity (40% v 31%). After adjustments for age, sex, smoking, indicators of socioeconomic status, and standard risk factors, the odds ratios (95% confidence intervals) for coronary heart disease of seropositivity to these agents were: 1.28 (0.93 to 1.75) for H pylori, 0.95 (0.66 to 1.36) for C pneumoniae, and 1.40 (0.96 to 2. 05) for cytomegalovirus. CONCLUSIONS: There is no good evidence of strong associations between coronary heart disease and serological markers of persistent infection with H pylori, C pneumoniae, or cytomegalovirus. To determine the existence of moderate associations between these agents and disease, however, larger scale studies will be needed that can keep residual confounders to a minimum. (+info)
Helicobacter pylori vacuolating toxin forms anion-selective channels in planar lipid bilayers: possible implications for the mechanism of cellular vacuolation. (5/5095)The Helicobacter pylori VacA toxin plays a major role in the gastric pathologies associated with this bacterium. When added to cultured cells, VacA induces vacuolation, an effect potentiated by preexposure of the toxin to low pH. Its mechanism of action is unknown. We report here that VacA forms anion-selective, voltage-dependent pores in artificial membranes. Channel formation was greatly potentiated by acidic conditions or by pretreatment of VacA at low pH. No requirement for particular lipid(s) was identified. Selectivity studies showed that anion selectivity was maintained over the pH range 4.8-12, with the following permeability sequence: Cl- approximately HCO3- > pyruvate > gluconate > K+ approximately Li+ approximately Ba2+ > NH4+. Membrane permeabilization was due to the incorporation of channels with a voltage-dependent conductance in the 10-30 pS range (2 M KCl), displaying a voltage-independent high open probability. Deletion of the NH2 terminus domain (p37) or chemical modification of VacA by diethylpyrocarbonate inhibited both channel activity and vacuolation of HeLa cells without affecting toxin internalization by the cells. Collectively, these observations strongly suggest that VacA channel formation is needed to induce cellular vacuolation, possibly by inducing an osmotic imbalance of intracellular acidic compartments.

Influences of Helicobacter pylori on serum pepsinogen concentrations in dialysis patients. (6/5095)BACKGROUND: Patients with impaired renal function have been known to have elevated concentrations of serum pepsinogens, which are raised by Helicobacter pylori infection of the stomach. The present study was performed to examine the effect of H. pylori infection on serum pepsinogen concentrations in dialysis patients. METHODS: Forty nine patients on dialysis and 48 subjects with no known kidney disease were examined for upper gastroduodenal endoscopy, H. pylori infection and serum concentrations of pepsinogen I and II. The status of H. pylori infection was evaluated from results of a urease test, histology and culture of biopsy specimens of the gastric mucosa. Serum pepsinogen levels were measured by radioimmunoassay. RESULTS: Serum concentrations of pepsinogen I and II were elevated in the dialysis patients in comparison with those in the controls (277.4+/-24.2 vs 52.6+/-4.0 pg/ml, P<0.01 for pepsinogen I, and 30.2+/-2.9 vs 14.9+/-1.3 pg/ml, P<0.01 for pepsinogen II). In both the dialysis patients and controls, those with H. pylori infection had significantly higher concentrations of serum pepsinogen I and II and a lower ratio of pepsinogen I to pepsinogen II than those without infection. Among the controls, 15 of 25 subjects with atrophic gastritis had a pepsinogen I/pepsinogen II ratio < or = 3.0, while only two out of 17 patients on dialysis fell into this range. CONCLUSIONS: We conclude that H. pylori status should be taken into account when serum pepsinogen concentrations are evaluated in dialysis patients. (+info)
Natural history of Helicobacter pylori infection in childhood: 12-year follow-up cohort study in a biracial community. (7/5095)We assessed the pattern of acquisition and loss of Helicobacter pylori infection in a cohort of 212 children from a biracial community with a homogeneous socioeconomic class. The children were followed over 12 years (1973-1974 to 1985-1986) from childhood to young adulthood. H. pylori status was assessed by the presence of serum IgG antibodies to H. pylori. At ages 7-9, 19% of children had H. pylori infection (40% of blacks vs. 11% of whites; P = .0001); 12 years later, 33% were seropositive. The higher prevalence among blacks remained (P = .0001). During follow-up, 22% of children became infected; the rate of acquisition was fourfold greater among blacks than among whites (P = .001). Over the 12-year period, infection was lost in 50% of whites compared with 4% of blacks who either remained infected or became reinfected. H. pylori infection in childhood is affected by both acquisition and loss of infection in different ethnic groups. This observation is critical for understanding the epidemiology and transmission of H. pylori infection. (+info)
KRAS mutations predict progression of preneoplastic gastric lesions. (8/5095)Eight hundred sixty-three subjects with atrophic gastritis were recruited to participate in an ongoing chemoprevention trial in Narino, Colombia. The participants were randomly assigned to intervention therapies, which included treatment to eradicate Helicobacter pylori infection followed by daily dietary supplementation with antioxidant micronutrients in a 2 x 2 x 2 factorial design. A series of biopsies of gastric mucosa were obtained according to a specified protocol from designated locations in the stomach for each participant at baseline (before intervention therapy) and at year three. A systematic sample of 160 participants was selected from each of the eight treatment combinations. DNA was isolated from each of these biopsies (n = 320), and the first exon of KRAS was amplified using PCR. Mutations in the KRAS gene were detected using denaturing gradient gel electrophoresis and confirmed by sequence analysis. Of all baseline biopsies, 14.4% (23 of 160) contained KRAS mutations. Among those participants with atrophic gastritis without metaplasia, 19.4% (6 of 25) contained KRAS mutations, indicating that mutation of this important gene is likely an early event in the etiology of gastric carcinoma. An important association was found between the presence of KRAS mutations in baseline biopsies and the progression of preneoplastic lesions. Only 14.6% (20 of 137) of participants without baseline KRAS mutations progressed from atrophic gastritis to intestinal metaplasia or from small intestinal metaplasia to colonic metaplasia; however, 39.1% (9 of 23) with baseline KRAS mutations progressed to a more advanced lesion after 3 years [univariate odds ratio (OR), 3.76 (P = 0.05); multivariate OR adjusted for treatment, 3.74 (P = 0.04)]. In addition, the specificity of the KRAS mutation predicted progression. For those participants with G-->T transversions at position 1 of codon 12 (GGT-->TGT), 19.4% (5 of 17) progressed (univariate OR, 2.4); however, 60.0% (3 of 5) of participants with G-->A transitions at position 1 of codon 12 (GGT-->AGT) progressed (univariate OR, 8.7; P = 0.004 using chi2 test).

Concomitant, sequential, and 7-day triple therapy in first-line treatment of Helicobacter pylori infection in Korea: study...
Helicobacter pylori infection causes peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer . Most international guidelines recommended triple-therapy regimens consisting of a proton pump inhibitor (PPI), clarithromycin, and amoxicillin/metronidazole for at least 7 days for the eradication of H. pylori [2-4]. However, the eradication frequency of standard triple therapy has fallen to less than 80% in many countries because of the rising prevalence of clarithromycin resistance [5-7]. The rate of clarithromycin resistance is reported to be as high as 37.3% in Korea. Consequently, the first-line eradication rate of triple therapy has been shown to be 74% according to a national database [8, 9]. Despite this issue, the standard triple-therapy regimen is still recommended for first-line therapy in Korea according to the revised guidelines, and it is the only regimen reimbursed by the Korean National Health Insurance Service .. Several strategies, including ...
The significance of E266K polymorphism in the NOD1 gene on Helicobacter Pylori infection: an effective force on pathogenesis? |...
The severity of Helicobacter pylori-related diseases varies greatly among infected individuals and seems to be influenced by both host and bacterial factors. Infection with a cytotoxin-associated gene pathogenicity island (Cag PAI)-positive H. Pylori strain causes a higher grade of gastric mucosal inflammation than an infection caused by a negative strain. Furthermore, such an infection is associated with severe atrophic gastritis and gastric adenocarcinoma. NOD1 protein is a cytosolic pattern recognition receptor that responds to peptidoglycan delivered by H. Pylori cag pathogenicity island. The aim of this study is to investigate whether the presence of the NOD1 G796A polymorphism has any influence on the clinical outcomes of Cag PAI-positive H. Pylori. Both Helicobacter pylori and CagA-positive 150 patients were considered eligible for the study. In this selected group, NOD1 G796A was detected by using polymerase chain reaction/restriction fragment length polymorphism. Activity and severity ...

Iron deficiency anaemia,helicobacter pylori infection and delayed pubertal growth | Archives of Disease in Childhood
We read with great interest the paper by Choe and colleagues which investigated a possible relationship betweenHelicobacter pylori infection, iron deficiency anaemia (IDA), and subnormal growth at puberty.1 The authors concluded that H pylori infection and related IDA, rather than bacterial infection alone, might cause delayed pubertal growth. However, we believe that these results need some consideration.. H pylori infection may cause IDA in different ways: (a) the bacterium can cause a decrease in the gastric juice of the concentration of ascorbic acid, which is the best promoter of non-heme iron absorption2; (b) H pylori may increase iron demand because iron is an essential bacterial growth factor; (c) H pyloricontains a 19.6 kDA protein resembling ferritin with a binding activity for heme iron in erythrocytes3; (d) acute or chronic blood loss and IDA are associated with typical H pylori related gastroduodenal lesions. In Choes study, the treatment of H pylori infection with antibiotics (but ...
High Dose PPI Triple Therapy Versus Sequential Therapy for Helicobacter Pylori Eradication - Full Text View - ClinicalTrials.gov
Background:. Helicobacter pylori (HP) play an important role in the pathogenesis of chronic gastritis, peptic ulcer diseases as well as gastric cancer. Helicobacter pylori eradication is a critical strategy to reduce aforementioned conditions. Proton-pump inhibitor (PPI)-based triple therapy (Standard dose PPIs+ Clarithromycin 1g/D + Amoxycillin 2g/D or Metronidazole 800 mg/D) is recommended as a frontline treatment in current guidelines for HP eradication, both from Thai and Second Asia-Pacific Consensus Guideline for H.pylori 2009. Unfortunately, it has been reported an unacceptably low eradication rate (,85%) of this regimen in a tertiary care hospital in Thailand. This occurrence is not surprised as the worldwide efficacy of this regimen had decreased to 50-75%. Of this, Clarithromycin resistance has been a major cause of the treatment failure.. Sequential therapy (ST) which consists of standard dose PPIs + amoxycillin 2 g/D for 5 days with 5 additional days of clarithromycin 1g/D + ...

How and when investigating and treating Helicobacter pylori infection in children | Acta Bio Medica Atenei Parmensis
For thousands of years humans have lived in symbiosis with Helicobacter pylori. This infection is acquired mainly during childhood and, despite it represents one of the most common infections in humans, only a minority of infected people may develop health issues and life-threatening diseases. For diagnosing Helicobacter pylori infection in children we can use, at first, non-invasive diagnostic tests, if clinical pattern and/or history are of suspicion. Then, invasive tests i.e. gastroscopy are necessary to confirm the infection. As antibiotics are not widely available in children affected by Helicobacter pylori infection, they should be chosen based on individual antibiotic susceptibility testing obtained by gastric biopsy specimens or the local antibiotic resistance pattern, in empirical treatment is chosen. Test and treat strategy in children should be avoided. In this brief review we summarize how and in which children the infection should be investigate and which the most appropriate ...

Y1 - 2010/7. N2 - Helicobacter pylori infection is associated with an inflammatory response in the gastric mucosa, leading to chronic gastritis, peptic ulcers, gastric carcinoma and gastric mucosa-associated lymphoid tissue (MALT) lymphomas. Recent studies have shown that apoptosis of gastric epithelial cells is increased during H. pylori infection. Apoptosis induced by microbial infections are factors implicated in the pathogenesis of H. pylori infection. The enhanced gastric epithelial cell apoptosis in H. pylori infection has been suggested to play an important role in the pathogenesis of chronic gastritis and gastric pathology. In addition to directly triggering apoptosis, H. pylori induces sensitivity to tumor-necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis in ...
The Hospital for Sick Children - Safety of 14C-UBT for diagnosis of Helicobacter pylori infection in pregnancy
Helicobacter pylori infection is the most important etiologic factor in chronic gastritis and gastroduodenal ulcer disease. Approximately 30% of patients with dyspepsia in North America are infected with H pylori; the annual incidence of new infections is about 0.5 per 100 persons in the susceptible population. In the developing world, prevalence among patients with dyspepsia is 80% to 90%, and the annual incidence of new infections is 3 or more per 100 susceptible persons. Presence of H pylori is closely related to development of gastric cancer. Eradication of the organism results in ulcer healing and reduces risk of ulcer recurrence and complications. Diagnostic methods for H pylori infection are direct or invasive (identifying the microorganism by gastric biopsy) and indirect or noninvasive (detecting certain characteristics of the bacteria). The latter can include the capacity of H pylori to hydrolyze urea (eg, urea breath test [UBT]) or quantification of specific antibodies (eg, various ...

Helicobacter pylori-related diseases: dyspepsia, ulcers and gastric cancer] | Read by QxMD
This article summarizes the main conclusions drawn from the presentations on Helicobacter pylori infection at Digestive Disease Week 2011. In developed countries, the prevalence of H. pylori infection has decreased, but seems to have reached a plateau at a fairly high level. Antibiotic resistance is increasing in several countries. H. pylori eradication does not contribute to the development of gastroesophageal reflux disease or worsen its course. The frequency of idiopathic peptic ulcers seems to be increasing. H. pylori eradication eliminates almost all episodes of peptic ulcer rebleeding; nevertheless, the use of non-steroidal anti-inflammatory drugs or H. pylori reinfection can lead to bleeding recurrence. H. pylori-negative patients with peptic ulcer bleeding more frequently have bleeding recurrences and higher mortality. In each particular population, there is a close correlation between the prevalence of H. pylori infection and the incidence of gastric cancer. H. pylori eradication is ...
Helicobacter pylori Eradication Therapy for Nonulcer Dyspepsia | Annals of Internal Medicine | American College of Physicians
I am troubled by Laine and colleagues conclusion that there is little support for the use of H. pylori eradication therapy in patients with nonulcer dyspepsia (1). Since infected persons have a two- to sixfold increased risk for gastric cancer and certain types of lymphoma, isnt it reasonable to therefore offer curative therapy? Do we really have longitudinal studies of sufficient duration to know the actual long-term risks associated with continued H. pylori infection? In the same issue, the findings of Ohkusa and associates that precancerous gastric lesions improved after eradication of H. pylori(2) certainly support the premise of long-term benefit ...

Post-immunisation gastritis and Helicobacter infection in the mouse: a long term study
BACKGROUND AND AIMS: Helicobacter pylori is a major cause of peptic ulcers and gastric cancer. Vaccine development is progressing but there is concern that immunisation may exacerbate Helicobacter induced gastritis: prophylactic immunisation followed by challenge with H felis or H pylori can induce a more severe gastritis in mice than seen with infection alone. The aim of this study was to investigate the relationship between immunity to Helicobacter infection and post-immunisation gastritis. METHODS: (1) C57BL/6 mice were prophylactically immunised before challenge with either H felis or H pylori. Histopathology and colonisation were assessed one month post-challenge. (2) C57BL/6 mice were prophylactically immunised against H felis infection and gastritis assessed up to 18 months post-challenge. RESULTS: Prophylactic immunisation induced a reduction in bacterial colonisation following H felis challenge which was associated with increased severity of active gastritis with neutrophil infiltration ...
Onset of Ulcerative Colitis after Helicobacter pylori Eradication Therapy: A Case Report. - Crohns Disease Forum - Support...
A 28-year-old male patient presented in January 1996 with the symptoms of ulcer like dyspepsia. There was no significant abnormality on physical examination, laboratory testing and abdominal ultrasound. Histology examination of the biopsy specimen taken during the upper endoscopy revealed Helicobacter pylori associated active gastritis only in the corporal part of the stomach. After two weeks eradication therapy (Omeprazole, Amoxicillin) he was well. Three months later, at the control endoscopy, granulomatous gastritis of the corporal localization was detected, without Helicobacter pylori present. Antral mucosa appeared normal, both, on endoscopy and histology examination. In July 1996 he started with cramping abdominal pain, mild periodical fever and episodes of watery diarrhea. In laboratory results we found nonspecific signs of inflammation. We repeated upper endoscopy, colonoscopy and enteroclysis--with evidence of segmental stenotic lesions of the upper part of ileum and jejunum. Again, we ...
HKU Scholars Hub: Evaluation of five commercial serological tests for the detection of Helicobacter pylori infection in Chinese
Background: Commercial serological tests for the detection of Helicobacter pylori infection must be locally validated. We evaluated the accuracy of five commercial tests in the Chinese population. Methods: Serum samples were collected from patients referred for upper endoscopy. Antral biopsies were taken for histological examination and culture of H. pylori. The gold standard for diagnosing H. pylori infection was positive histological staining and/or positive H. pylori culture. The serum samples were tested for H. pylori antibodies using the following tests: (i) Cobas Core Anti-H. pylori EIA: (ii) GAP IgG; (iii) GAP IgM; (iv) H. pylori microwell EIA (Quidel): and (v) Premier H. pylori. The sensitivity, specificity and accuracy of each test was calculated according to the manufacturers instructions or according to a new cut-off value. Results: A total of 158 patients were recruited amongst whom 114 (72%) were H. pylori-positive. Indeterminate results varied from 7% to 19%. The accuracy of the ...
Effect of early and current Helicobacter pylori infection on the risk of anaemia in 6.5-year-old Ethiopian children | BMC...
Epidemiological and clinical studies in high income countries have suggested that Helicobacter pylori (H. pylori) may cause anaemia, but evidence is lacking from low income countries.We examined associations between H. pylori infection in early childhood and anaemia at the age of 6.5 years in an Ethiopian birth cohort. In 2011/12, 856 children (85.1 % of the 1006 original singletons in a population-based birth cohort) were followed up at age six and half. An interviewer-led questionnaire administered to mothers provided information on demographic and lifestyle variables. Haemoglobin level and red cell indices were examined using an automated haematological analyzer (Cell Dyn 1800, Abbott, USA), and stool samples analyzed for H. pylori antigen. The independent effects of H. pylori infection (measured at age 3.5 and 6.5 years) on anaemia, haemoglobin level, and red cell indices (measured at age 6.5 years) were determined using multiple logistic and linear regression. The prevalence of anemia was 34.8 %

Prevalence of helicobacter pylori infection among children living in a rural setting in Sub-Saharan Africa | BMC Public Health ...
Helicobacter pylori infection affects more than half of the worlds population. It is generally acquired during childhood with no symptoms but has long- term clinical sequelae. This study estimated the prevalence of H. pylori infection amongst children in a rural environment in Africa. We conducted a cross-sectional study over a four (4)-month period within two rural communities. 240 asymptomatic children were tested using lateral flow immunochromatographic assay for the qualitative detection of H. pylori antigen in a fecal specimen. Statistical analysis and processing was done using Stata version 11. The mean age of the participants was 10.5 ± 2.7 years with the predominant age range being 8-10 years (34.6%), and a mean household size of 7.1 ± 1.7. The study population showed a female preponderance of 57.1%. 88% of the H. pylori positive children lacked pipe and borehole drinking water. All of the positive H. pylori children practiced open-air defecation. The overall prevalence of H. pylori infection

Helicobacter pylori infection assessed by ELISA and by immunoblot and noncardia gastric cancer risk in a prospective study: the...
BACKGROUND: In epidemiological studies, Helicobacter pylori infection is usually detected by enzyme-linked immunosorbent assay (ELISA). However, infection can spontaneously clear from the mucosa during the progression of atrophy and could lead to substantial under-detection of infection and underestimation of its effect on gastric cancer (GC) risk. Antibodies detected by western blot are known to persist longer after the loss of the infection. METHODS: In a nested case-control study from the Eurogast-EPIC cohort, including 88 noncardia GC cases and 338 controls, we assessed the association between noncardia GC and H. pylori infection comparing antibodies detected by western blot (HELICOBLOT2.1) to those detected by ELISA (Pyloriset EIA-GIII(®)). RESULTS: By immunoblot, 82 cases (93.2%) were H. pylori positive, 10 of these cases (11.4%) were negative by ELISA and only 6 cases (6.8%) were negative by both ELISA and immunoblot. Multivariable odds ratio (OR) for noncardia GC comparing immunoglobulin G

Helicobacter pylori infection permanently changes gastric environment - Healthcanal.com : Healthcanal.com
The modern methods used in medical research are increasingly demonstrating the importance of the human microbiome for a persons general health. The microbiome refers to all the bacteria that live in an organ system or ecosystem. It is constantly adapting to changes in the ecosystem, such as changes in lifestyle or eating habits, for example.. A few months ago, working in collaboration with the Austrian Society of Gastroenterology and Hepatology, a team of researchers led by infectionologist Christoph Steininger from the Division of Infectious Diseases and Tropical Medicine at MedUni Viennas Department of Medicine I conducted a large-scale study into antibiotic resistance of Helicobacter pylori in Austria.. Helicobacter pylori is a common bacterium that can cause gastritis and stomach cancer. Symptoms can vary a great deal, ranging from loss of appetite and nausea through to upper abdominal pain. It was found that Helicobacter pylori infection is often resistant to standard antibiotics and ...
RCAAP - Curcumin Inhibits Gastric Inflammation Induced by Helicobacter Pylori Infection...
Helicobacter pylori (H. pylori) infection triggers a sequence of gastric alterations starting with an inflammation of the gastric mucosa that, in some cases, evolves to gastric cancer. Efficient vaccination has not been achieved, thus it is essential to find alternative therapies, particularly in the nutritional field. The current study evaluated whether curcumin could attenuate inflammation of the gastric mucosa due to H. pylori infection. Twenty-eight C57BL/6 mice, were inoculated with the H. pylori SS1 strain; ten non-infected mice were used as controls. H. pylori infection in live mice was followed-up using a modified 13C-Urea Breath Test (13C-UBT) and quantitative real-time polymerase chain reaction (PCR). Histologically confirmed, gastritis was observed in 42% of infected non-treated mice at both 6 and 18 weeks post-infection. These mice showed an up-regulation of the expression of inflammatory cytokines and chemokines, as well as of toll-like receptors (TLRs) and MyD88, at both time ...

Eradication of Helicobacter pylori: therapies and clinical implications. | Postgraduate Medical Journal
This review presents a critical evaluation of the role of Helicobacter pylori eradication in the management of peptic ulcer disease and non-ulcer dyspepsia. On current evidence, H. pylori eradication therapy seems likely to emerge as the most rational and cost-effective treatment for duodenal ulcer. The role of H. pylori eradication in the treatment of gastric ulcer and non-ulcer dyspepsia is unclear and requires further study. The emerging problem of antibiotic resistance in H. pylori is of major clinical importance and a prime cause of treatment failure. There is increasing evidence of a link between H. pylori and gastric cancer but it is premature to recommend large-scale eradication of H. pylori as a valid strategy for the primary prevention of gastric cancer. The search continues for the ideal H. pylori eradication regimen.. ...

Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that included furazolidone, levofloxacin and lansoprazole in patients with persistent Helicobacter pylori infection, who had failed to respond to at least one prior eradication treatment regimen. This study included 48 patients with peptic ulcer disease. Helicobacter pylori infection was confirmed by a rapid urease test and histological examination of samples obtained from the antrum and corpus during endoscopy. The eradication therapy consisted of a 7-day twice daily oral administration of lansoprazole 30 mg, furazolidone 200 mg and levofloxacin 250 mg. Therapeutic success was confirmed by a negative rapid urease test, histological

BACKGROUND/AIMS A two-year, prospective, nationwide multicenter study was undertaken to evaluate the effect of Helicobacter pylori eradication on the development of reflux esophagitis (RE) and gastroesophageal reflux disease (GERD) symptoms in the Korean population. METHODS In total, 1,489 subjects without RE were enrolled at the outpatient clinics of 12 tertiary hospitals nationwide, and 452 subjects underwent follow-up (F/U) for 2 years to evaluate the development of RE and GERD symptoms. RESULTS RE was found in 33 subjects (7.3% of 452 subjects) and 14 subjects (7.3% of 192 subjects) during the first and second year of F/U, respectively. H. pylori status was not associated with the development of RE. RE was found in six (9.0%) of 67 H. pylori-negative patients, in 26 (11.2%) of 233 eradicated subjects and in eight (7.0%) of 114 noneradicated subjects (p=0.532). Multivariate analysis showed that age ≥60 years (odds ratio [OR], 7.11; 95% confidence interval [CI], 1.92 to 26.41), alcohol

In 1991 Wotherspoon et al 1 showed a close association between Helicobacter pylori infection and gastric mucosa-associated lymphoid tissue (MALT) lymphoma (GML) with the organism present in 92% of cases. Other studies have shown this association to be varying between 42% and 100%. In vitro studies at that time showed that lymphoma cell proliferation was associated with the presence of H. pylori mediated through specific tumour infiltrating T cells in a contact dependant manner. In the light of this finding Wotherspoon et al 1 were able to demonstrate that eradication of H. pylori induced lymphoma regression. In a recent Gut article, Nakamura et al 2 demonstrated that H. pylori eradication therapy can result in durable lymphoma regression in the majority of cases.

A better method for confirming Helicobacter pylori infection in Mongolian gerbils - Semantic Scholar
Background. Our aim was to evaluate the accuracy of the stool antigen test and the optimal time point for detecting Helicobacter pylori infection in a Mongolian gerbil model. Methods. We inoculated 8-week-old Mongolian gerbils with H. pylori (Vac A (+)/CagA(+)). The gerbil-infected model was developed as follows: H. pylori was put into broth (about 109 CFU/ml), and 50 gerbils were then fed with 1 ml intragastrically twice within a 3-day interval. Another ten gerbils were fed broth only. Twenty-six weeks after the inoculation, the gerbils were killed. The gastric mucosa was sampled for a series of examinations including culture, histology, rapid urease test, and polymerase chain reaction. Stool samples for a stool antigen test, H. pylori-specific stool antigen assay (HpSA), were collected during weeks 4, 6, 8, 12, and 26 after inoculation. Of the 50 gerbils inoculated with H. pylori, the inoculation was successful in 88%. Severe active gastritis, ulceration, and intestinal metaplasia were obvious.

The numbers of chromogranin A (CgA)-positive, gastrin-positive and gastric inhibitory polypeptide (GIP)-positive cells in H. pylori-infected groups was increased significantly compared with the non-infected case. However, CgA-positive and gastrin-positive cells then decreased from 50 through 100 ...
Interferon gamma and interleukin 4 secreting cells in the gastric antrum in Helicobacter pylori positive and negative gastritis...
Little is known of the function of the T cells in the inflammatory infiltrate in Helicobacter pylori associated gastritis. This study thus measured T cell in vivo activation by enumerating the frequency of interferon gamma (IFN gamma) and interleukin 4 (IL 4) secreting cells isolated from the gastric antral mucosa in patients with or without gastritis and in H pylori positive and negative gastritis. Fifty four samples were examined for cytokine secretion. Four antral biopsy specimens from each patient (n = 51) were taken during diagnostic endoscopy. One was used to estimate histological gastritis and the presence of H pylori, and three of the samples were used to isolate T cells by enzymatic digestion. IFN gamma and IL 4 secreting cells were enumerated by ELISPOT. Thirty four samples had gastritis and 79% of those were H pylori positive. None of the samples from non-inflamed mucosa had H pylori. The numbers of IFN gamma secreting cells per 10(5) T cells were higher in gastritis than in normal ...
Relationship of gastroscopic features to histological findings in gastritis and Helicobacter pylori infection in a general...
Background & alms: The main cause of chronic gastritis is Helicobacter pylori (H. pylori). Clinical manifestations of chronic gastritis are ulcer disease, gastric cancer and mucosa-associated lymphoma tissue (MALT) lymphoma in the stomach. It is uncertain whether gastritis can be diagnosed macroscopically at endoscopy. H. pylori infection may be diagnosed by several different methods, the accuracy of which needs to be explored. Some individuals with H. pylori related chronic gastritis will develop atrophy of the gastric mucosa. This condition is the main risk factor for cancer development and may also be associated with vitamin B12 deficiency leading to hyperhomocysteinaemia. The natural history of chronic gastritis in terms of development of atrophy and ulcer disease in the adult general population is largely unknown.. Material & methods: A sample of 50 I volunteers from the general population in the municipality of Linköping was examined with esophago-gastro-duodenoscopy (EGD) with biopsy. ...
Hazarders of Smoking and Helicobacter pylori Infection on Gastric Mucosa among Egyptian Patients with Dyspepsia
Background: Smoking is hazardous to almost any organ in the body and has a harmful effect on the gastric mucosa. Objective: The main goal of this study was to evaluate the synergistic effect of smoking and H. pylori infection on gastric mucosal among dyspeptic Egyptian patients. Patients and Methods: A cross-sectional study was conducted among 240 consecutive patients with dyspepsia who underwent upper endoscopy and histopathological examination of gastric biopsies at Zagazig and Tanta University Hospital with H. pylori-positivity assessment by stool antigen and rapid urease test. Results: There were 60 smoker patients and 180 non-smoker patients. Erosive gastritis was more prevalent in smoker patients than non-smoker patients (46.7% versus 15.6%, p = 0.00). In H. pylori-positive patients (36.7% of all patients), smokers were more prevalent than non-smokers in the development of intestinal metaplasia (20% versus 0%, p = 0.003), erosive gastritis (80% versus 30%, p = 0.00), glandular atrophy (20% versus

H Pylori and Chronic Urticaria / Hives | h pylori symptoms
However in many cases, there is no known trigger, leading to a diagnosis of idiopathic chronic urticarial.. A number of studies have indicated that H pylori infection may play a role in the development of urticaria / hives because of the damage caused to the stomach by the infection.. The inflammatory response in the stomach and small intestine (gastritis & duodenitis, respectively) that is caused by H pylori infection may lead to an increase in permeability of the delicate gut lining.. In other words, tiny gaps and holes appear in the stomach lining, which allow larger, undigested particles of food, bacterial antigens or chemicals into the blood. Once there, the immune system mounts a response, leading to inflammation on the skin.. Several other mechanisms involving the immune system may also contribute to the development of chronic urticaria in H pylori-infected people.. Some studies - I have seen the data from 16 studies in total - have shown partial or complete remission in urticaria in ...

IBIMA Publishing Relationship between ABO Blood Groups and Helicobacter Pylori Infection among Patients with Dyspepsia
Helicobacter pylori infection is a high prevalence infection worldwide, and it is more common in developing countries than developed ones (Magalhães and Luzza, 2006). It is a major risk factor for chronic gastritis, peptic ulcer and gastric cancer (Fock and Ang, 2010). The ABO blood group system is the most important in human blood transfusion. The blood group antigens present on RBC are permanent, fixed and lifelong biological markers of any individual, they are almost as individual as fingerprints (Ravn and Dabelstein, 2000). The distribution of the ABO blood groups varies in populations throughout the world (Garratty et al., 2004). In addition to clinical significance for transfusion and transplantation, it is becoming increasingly apparent that ABO antigens are of biological significance and may be associated with predisposition to, or protection from many diseases (Reid and Bird, 1990).. Many authors reported an association between blood group O and H. pylori infection (Kanbay, et al., ...
Sabinet | A case of severe vitamin B12 deficiency secondary to Helicobacter pylori gastritis
Helicobacter pylori (H. pylori) is a gram-negative bacterium that colonizes the human stomach and is a major gastric infection worldwide. Approximately over 50% of the adult population in developed countries and 80% in developing countries are infected with this bacterium. H. pylori infection is invariably associated with gastritis, and triggers autoantibodies by a mechanism of molecular mimicry. It may play an important role in the impairment of vitamin B12 absorption leading to pernicious anaemia. This case report highlights H. pylori as a causative agent in vitamin B12 deficiency. H. pylori treatment reverse the underlying pathogenesis and corrects the vitamin B12 deficient state in selected individuals.

AIMS: To investigate the localisation of Helicobacter pylori antigens and the expression of human heat shock proteins (HSP) in stomachs affected by MALT lymphoma. METHODS: Surgically resected stomachs from 24 patients with MALT lymphoma were immunostained with anti-H pylori rabbit antibodies (ORP-1 and ORP-2) and anti-human HSP60 mouse monoclonal antibodies (mAb) (LK-1 and LK-2). RESULTS: Follicular dendritic cells of germinal centres in the stomachs affected by MALT lymphoma were immunostained with anti-H pylori polyclonal antibodies and with anti-human HSP60 mAb, as were the epithelial cells. None of the lymph node samples reacted. CONCLUSIONS: Human HSP60, which cross reacts with anti-H pylori polyclonal antibodies, is often expressed on follicular dendritic cells in gastric MALT lymphoma tissues and may be aetiologically relevant to lymphomagenesis of MALT lymphoma. ...
Genome sequence analysis of Helicobacter pylori strains associated with gastric ulceration and gastric cancer | BMC Genomics |...
Persistent colonization of the human stomach by Helicobacter pylori is associated with asymptomatic gastric inflammation (gastritis) and an increased risk of duodenal ulceration, gastric ulceration, and non-cardia gastric cancer. In previous studies, the genome sequences of H. pylori strains from patients with gastritis or duodenal ulcer disease have been analyzed. In this study, we analyzed the genome sequences of an H. pylori strain (98-10) isolated from a patient with gastric cancer and an H. pylori strain (B128) isolated from a patient with gastric ulcer disease. Based on multilocus sequence typing, strain 98-10 was most closely related to H. pylori strains of East Asian origin and strain B128 was most closely related to strains of European origin. Strain 98-10 contained multiple features characteristic of East Asian strains, including a type s1c vacA allele and a cagA allele encoding an EPIYA-D tyrosine phosphorylation motif. A core genome of 1237 genes was present in all five strains for which

There is no current standard rescue treatment for dual drug-resistant strains of Helicobacter pylori (H. pylori). This aim of this study was to investigate the efficacy of rifabutin-based triple therapy for patients infected with dual drug-resistant strains to clarithromycin and levofloxacin. After 2 or 3 H. pylori treatment failures, patients underwent upper endoscopy with tissue biopsies. Phenotypic and genotypic resistances were determined using agar dilution test and polymerase chain reaction with direct sequencing, respectively. Patients infected with dual drug-resistant (clarithromycin and levofloxacin) strains and receiving rifabutin-based triple therapy (rifabutin 150 mg bid, amoxicillin 1 g bid and esomeprazole 40 mg bid for 10 days) were enrolled. Eradication status was determined by 13C-urea breath test 4 weeks after treatment completion. A total of 39 patients infected with dual drug-resistant strains were enrolled in this study, with a mean age of 55.9 years. The eradication rate was 79.5%

The association between proinflammatory cytokine gene polymorphisms and gastric diseases related to Helicobacter pylori varies by population and geographic area. Our objective was to determine if the IL-1B -511 T|C and -31 C|T polymorphisms and H. pylori vacA genotypes are associated with risk of chronic gastritis and gastric ulcer in a Mexican population. We conducted endoscopic studies in 128 patients with symptoms of dyspepsia. We took two biopsies from the body, antrum, or ulcer edge from each patient, and classified our histopathological findings according to the Sydney System. H. pylori infection and vacA genotyping were accomplished via PCR from total DNA of the gastric biopsies. We confirmed the presence of anti-H. pylori serum IgG and IgM in 102 control subjects. In both case subjects and control subjects, the IL-1B -511 T|C polymorphism was genotyped by PCR-RFLPs and the IL-1B -31 C|T polymorphism was genotyped by pyrosequencing. Sixty-two point seven (62.7%) of the 102 control subjects were H

Y1 - 2000/1/1. N2 - Helicobacter pylori is believed to cause chronic active gastritis. Infection/colonization of the gastric mucosal surface induces a mucosal inflammatory reaction in the form of lymphocytic aggregates, plasma cells and, particularly, neutrophils, which may, in turn, damage the mucosal epithelium. In vitro studies demonstrate that, in culture, the bacilli are readily phagocytosed by neutrophils, this evoking a neutrophilic oxidative burst. However, it has been claimed that neutrophils do not phagocytose H. pylori in vivo. In this study of 19 endoscopic biopsies of gastric mucosa with H. pylori-associated gastritis, Cresyl violet staining for light microscopy and electron microscopy are used to demonstrate that, in vivo, neutrophils actively phagocytose and destroy the bacilli in the ...

Platelet activation in mice and human Helicobacter pylori infection.
Extracts of Helicobacter pylori (HP) have been shown to induce leukocyte adhesion in mesenteric venules, but the effects of HP infection on gastric microvessels are unknown. Inflammatory cell interactions in the gastric microcirculation were studied by intravital videomicroscopy in mice inoculated with either saline or fresh isolates of HP. Platelet aggregates were detected and quantified in murine portal blood, while endothelial P-selectin expression was determined using the dual radiolabeled mAb technique. Platelet activation and aggregation were studied in HP-infected patients and controls by measuring the platelet-aggregate ratio and platelet P-selectin expression. HP infection induced a marked increase in the flux of rolling leukocytes and the appearance of platelet and leukocyte- platelet aggregates in murine gastric venules. The HP-induced rolling and platelet aggregate formation was abrogated by mAbs against L- or P-, but not E- selectin. Endothelial cell expression of P-selectin was not ...
Culturable Bacterial Microbiota of the Stomach of Helicobacter pylori Positive and Negative Gastric Disease Patients
Human stomach is the only known natural habitat of |i|Helicobacter pylori|/i| (|i|Hp|/i|), a major bacterial pathogen that causes different gastroduodenal diseases. Despite this, the impact of |i|Hp|/i| on the diversity and the composition of the gastric microbiota has been poorly studied. In this study, we have analyzed the culturable gastric microbiota of 215 Malaysian patients, including 131 |i|Hp|/i| positive and 84 |i|Hp|/i| negative individuals that were affected by different gastric diseases. Non-|i|Hp|/i| bacteria isolated from biopsy samples were identified by matrix assisted laser desorption ionization-time of flight mass spectrometry based biotyping and |i|16SrRNA|/i| sequencing. The presence of |i|Hp|/i| did not significantly modify the diversity of the gastric microbiota. However, correlation was observed between the isolation of Streptococci and peptic ulcer disease.
