Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments. Regarding the untouched area, Hero 642 system showed 22.78% ± 6.42% and Reciproc R40 34.35% ± 8.52%. Neither instrument achieved complete cross-sectional root canal debridement. Hero 642 system rotary taper 0.02 instruments achieved significant greater wall contact perimeter and area compared to reciprocate the Reciproc R40 taper 0.06 instrument.. Hero 642 achieved higher wall contact perimeter and area but, regardless of instrument size and taper, vital pulp during.

This study showed that the anti-inflammatory effect of the iron-responsive product DHA in arthritis can be monitored by an iron-like radioactive tracer (. Attenuated vascular reactivity during pregnancy suggests that the systemic vasodilatory state partially depletes nitric oxide bioavailability. Preliminary data support the potential for MRI to identify vascular dysfunction in vivo that underlies PE. Level of Evidence 2 Technical Efficacy Stage 1 J. MAGN. RESON. IMAGING 2021;53:447-455.. La evaluación de riesgo es importante para predecir los resultados postoperatorios en pacientes con cáncer gastroesofágico. Este estudio de cohortes tuvo como objetivo evaluar los cambios en la composición corporal durante la quimioterapia neoadyuvante e investigar su asociación con complicaciones postoperatorias. MÉTODOS: Los pacientes consecutivos con cáncer gastroesofágico sometidos a quimioterapia neoadyuvante y cirugía con intención curativa entre 2016 y 2019, identificados a partir de una base de datos específica, se incluyeron en el estudio. Se utilizaron las imágenes de tomografía computarizada, antes y después de la quimioterapia neoadyuvante, para evaluar el índice de masa muscular esquelética, la sarcopenia y el índice de grasa visceral y subcutánea.. In this in vitro premature infant lung model, HF oscillation of BCPAP was associated with improved CO. Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.. Inflammatory markers are highly related to signs of systemic hypoperfusion in CS. Moreover, high PCT and IL-6 levels are associated with poor prognosis.. These findings indicate that Tetrapleura tetraptera fruit has a protective potential against stroke through modulation of redox and electrolyte imbalances, and attenuation of neurotransmitter dysregulation and other neurochemical dysfunctions. Tetrapleura tetraptera fruit could be a promising source for the discovery of bioactives for stroke therapy.

As one of the most prevalent infections globally, Helicobacter pylori (H. pylori) continues to present diagnostic and therapeutic challenges for clinicians worldwide. Diagnostically, the "test-and-treat" strategy is the recommended approach for healthcare practitioners when managing this potentially curable disease. The choice of testing method should be based on several factors including patient age, presenting symptoms, and medication use, as well as test reliability, availability, and cost. With rising antibiotic resistance, particularly of macrolides, care must be taken to ensure that therapy is selected based on regional resistance patterns and prior antibiotic exposure. In the USA, macrolide antibiotic resistance rates in some areas have reached or exceeded a generally accepted threshold, such that clarithromycin triple therapy may no longer be an appropriate first-line empiric treatment. Instead, bismuth quadruple therapy should be considered, while levofloxacin-based or alternative macrolide-containing therapies are also options. Once treated, it is essential to test for eradication as untreated H. pylori is associated with serious complications including peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma, and gastric cancer. This review article aims to consolidate current knowledge of H. pylori infection with a particular emphasis on diagnostic and treatment strategies.

National Danish guidelines for the diagnosis and treatment of Helicobacter pylori (Hp) infection have been approved by the Danish Society for Gastroenterology. All patients with peptic ulcer disease, gastric cancer, and MALT lymphoma should be tested for Hp. We also recommend testing in first degree relatives to patients with gastric cancer, in NSAID-naive patients, who need long-term NSAID therapy, and in patients presenting with dyspepsia and no alarm symptoms. Non-endoscoped patients can be tested with a urea-breath test or a faecal antigen test. Endoscoped patients can be tested with a rapid urease test. Proton pump inhibitor therapy should be stopped at least 1 week prior to Hp testing. All infected patients should be offered Hp eradication therapy. First-line treatment is 7-day triple therapy with a proton pump inhibitor and clarithromycine in combination with metronidazole or amoxicilline. Quadruple therapy for 2 weeks with bismuthsubsalicylate, tetracycline, metronidazole and a proton pump inhibitor is recommended in case of treatment failure. Hp testing should be offered to all patients after eradication therapy but is mandatory in patients with ulcer disease, noninvasive gastric cancer or MALT lymphoma. Testing after eradication should not be done before 4 weeks after treatment has ended.

Helicobacter pylori is becoming increasingly important as a gastrointestinal pathogen and aetilogical agent in several disease states. This review attempts to clarify the role of Helicobacter pylori and importantly, simplify treatment options.

The discovery of Helicobacter pylori is arguably the most significant advance made in gastroduodenal pathology this century. It is the most important cause of chronic gastritis, and almost certainly the major aetiological factor responsible for duodenal ulcer and probably for gastric ulcer as well. Evidence is accumulating which suggests that it may play an important role in the pathogenesis of gastric cancer. H. pylori is thought to be transmitted by the faecal-oral route or possibly oral-oral route, with iatrogenic transmission also reported. The prevalence of H. pylori infection increases with age, is commonest in developing countries, in certain ethnic minorities and those in lower socio-economic and educational groups. The organism can be eradicated using combinations of antibiotics; when treatment is successful inflammatory changes resolve, duodenal ulcers heal and do not subsequently recur.

Preliminary data support the potential for MRI to identify vascular dysfunction in vivo that underlies PE. Level of Evidence 2 Technical Efficacy Stage 1 J. MAGN. RESON. IMAGING 2021;53:447-455.. La evaluación de riesgo es importante para predecir los resultados postoperatorios en pacientes con cáncer gastroesofágico. Este estudio de cohortes tuvo como objetivo evaluar los cambios en la composición corporal durante la quimioterapia neoadyuvante e investigar su asociación con complicaciones postoperatorias. MÉTODOS: Los pacientes consecutivos con cáncer gastroesofágico sometidos a quimioterapia neoadyuvante y cirugía con intención curativa entre 2016 y 2019, identificados a partir de una base de datos específica, se incluyeron en el estudio. Se utilizaron las imágenes de tomografía computarizada, antes y después de la quimioterapia neoadyuvante, para evaluar el índice de masa muscular esquelética, la sarcopenia y el índice de grasa visceral y subcutánea.. In this in vitro premature infant lung model, HF oscillation of BCPAP was associated with improved CO. Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.. Inflammatory markers are highly related to signs of systemic hypoperfusion in CS. Moreover, high PCT and IL-6 levels are associated with poor prognosis.. These findings indicate that Tetrapleura tetraptera fruit has a protective potential against stroke through modulation of redox and electrolyte imbalances, and attenuation of neurotransmitter dysregulation and other neurochemical dysfunctions. Tetrapleura tetraptera fruit could be a promising source for the discovery of bioactives for stroke therapy.

We investigated to compare the effect of empirical therapy vs clarithromycin resistance-guided tailored therapy (tailored therapy) for eradication of Helicobacter pylori.. In this prospective, single center, open-label randomized controlled trial, we enrolled 72 patients with H. pylori infection from January 2019 through June 2019 in Korea. The patients were randomly assigned to both groups received empirical (n = 36) or tailored therapy (n = 36). Empirical therapy was defined as triple therapy with esomeprazole, amoxicillin, and clarithromycin for 10 days irrespective of clarithromycin resistance. Tailored therapy was triple or quadruple therapy with esomeprazole, metronidazole, tetracycline, and bismuth for 10 days based on genotype markers of resistance determined by gastric biopsy. Resistance-associated mutations in 23S rRNA were confirmed by multiplex polymerase chain reaction. Eradication status was assessed by C-urea breath test, and the primary outcome was eradication rates.. H. pylori was eradicated in 27 patients (75.0%), given empirical therapy and 32 patients (88.9%) treated with tailored therapy (P = 0.136) in intention-to-treat analysis. In per protocol analysis, the eradication rate was 97.0% and 81.8% in tailoredvs empirical groups (P = 0.046). Although clarithromycin-resistant H. pylori was eradicated in 3/9 (33.3%) with empirical therapy, it was treated in 11/12 (91.7%) with tailored therapy (P = 0.009). There was no difference in compliance between 2 groups. The rate of adverse events of the tailored group was higher than that of the empirical group (P = 0.036) because quadruple therapy had more side effects than those of triple therapy (P = 0.001).. Tailored therapy based on polymerase chain reaction is a good alternative to increase eradication rates in a region of high prevalence of clarithromycin resistance (see Visual Abstract, Supplementary Digital Content 1, http://links.lww.com/CTG/A342).

To clarify the full range of benefits and adverse consequences of Helicobacter pylori eradication as a strategy for gastric cancer prevention, the community-based intervention trial was launched in Linqu County, China.. A total of 184,786 residents aged 25-54 years were enrolled in this trial and received (13)C-urea breath test. H. pylori positive participants were assigned into two groups, either receiving a 10-day quadruple anti-H. pylori treatment or lookalike placebos together with a single dosage of omeprazole and bismuth.. The prevalence of H. pylori in trial participants was 57.6%. A total of 94,101 subjects completed the treatment. The overall H. pylori eradication rate was 72.9% in the active group. Gender, body mass index, history of stomach disease, baseline delta over baseline-value of (13)C-urea breath test, missed medication doses, smoking and drinking were independent predictors of eradication failure. The missed doses and high baseline delta over baseline-value were important contributors in men and women (all Ptrend<0.001). However, a dose-response relationship between failure rate and smoking or drinking index was found in men (all Ptrend<0.001), while high body mass index (Ptrend<0.001) and history of stomach disease were significant predictors in women. The treatment failure rate increased up to 48.8% (OR 2.87, 95% CI 2.24 to 3.68) in men and 39.4% (OR 2.67, 95% CI 1.61 to 4.42) in women with multiple factors combined.. This large community-based intervention trial to eradicate H. pylori is feasible and acceptable. The findings of this trial lead to a distinct evaluation of factors influencing eradication that should be generally considered for future eradication therapies.. ChiCTR-TRC-10000979 in accordance with WHO ICTRP requirements.

The increasing trend of antibiotic resistance requires effective second-line Helicobacter pylori (H. pylori) treatment in high prevalence area of H. pylori. The aim of our study was to evaluate the reinfection rate of H. pylori after second-line treatment that would determine the long-term follow up effect of the rescue therapy.. A total of 648 patients who had failed previous H. pylori eradication on standard triple therapy were randomized into two regimens: 1, esomeprazole (20 mg b.i.d), tripotassium dicitrate bismuthate (300 mg q.i.d), metronidazole (500 mg t.i.d), and tetracycline (500 mg q.i.d) (EBMT) or 2, moxifloxacin (400 mg q.d.), esomeprazole (20 mg b.i.d), and amoxicillin (1000 mg b.i.d.) (MEA). At four weeks after completion of eradication therapy, H. pylori tests were performed with 13C urea breath test or invasive tests. In patients who maintained continuous H. pylori negativity for the first year after eradication therapy, H. pylori status was assessed every year. For the evaluation of risk factors of reinfection, gender, age, clinical diagnosis, histological atrophic gastritis or intestinal metaplasia were analyzed.. The recrudescence rate of the EBMT was 1.7% and of the MEA group 3.3% (p = 0.67). The annual reinfection rate of H. pylori of EBMT was found to be 4.45% and the MEA group 6.46%. Univariate analysis (Log-rank test) showed no association with any clinical risk factor for reinfection.. The long-term reinfection rate of H. pylori stayed low in both of bismuth-containing quadruple therapy and moxifloxacin-based triple therapy; thus reinfection cannot affect the choice of second-line treatment.. Clinical Trial Registration Number NCT01792700.

The physiology of gastrointestinal transfer function after proximal gastrectomy with bypass-tract reconstruction is not well understood. We applied a simultaneous dual-radionuclide method with a hepatobiliary imaging and gastric emptying study to evaluate physiologic alterations occurring after surgery.. Nineteen patients with early gastric cancer, including 9 preoperative control patients and 10 who had proximal gastrectomy and double-tract reconstruction surgery were examined by dual-radionuclide hepatobiliary and gastric emptying studies (99mTc PMT and 111In DTPA). Retention fraction in the stomach at 3 minutes (R3) and 60 minutes (R60) and gastric emptying half-time (GET) were calculated. Bile reflux and mixture of bile and food were also evaluated.. The retention fractions of R3 and R60 were significantly lower in the double-tract reconstruction group than those in the preoperative group. GET differed significantly between the double-tract and preoperative groups (20.7 min +/- 7.1 min and 36.2 min +/- 11.0 min, p = 0.0018). The mixture of bile and food was not good in the double-tract reconstruction group (p = 0.014 vs. preoperative). Patients with a large residual stomach showed slower initial emptying (p = 0.0068) and a better mixture of bile and food (p = 0.058) compared to those with a small residual stomach. The bile reflux was not significantly increased after surgery.. The dual-radionuclide gastrointestinal and hepatobiliary imaging was feasible and could demonstrate characteristic transit patterns of the foods and bile in the double-tract reconstruction procedure. A larger residual stomach, if possible, is desirable to provide better transfer and mixing of bile and foods.

The inflammatory process involving Helicobacter pylori-associated gastritis is thought to lead to epithelial damage and contribute to the development of gastric cancer. Evidence exists from animal and in vitro studies suggesting that tetracyclines have both anti-inflammatory and tissue-protectant effects unrelated to their antimicrobial activity. We attempted to modulate components of H. pylori's inflammatory process by: (i) eliminating the infection; (ii) using tetracycline to alter the host's reaction to the infection without reducing the bacterial load; and (iii) using calcium to counteract the effect of excessive dietary salt.. We conducted a 16-week placebo-controlled clinical trial with 374 H. pylori-associated gastritis patients randomly assigned to one of five groups: (1) triple therapy consisting of metronidazole, amoxicillin and bismuth subsalicylate for 2 weeks, followed by bismuth alone for 14 weeks; (2) calcium carbonate; (3) triple therapy and calcium carbonate; (4) tetracycline; or (5) placebo.. Subjects in the tetracycline and triple therapy groups, but not the calcium carbonate only group, showed a reduction in inflammation and epithelial damage vs. those in the placebo group, independent of a change in H. pylori density and other factors. Our results also indicate that epithelial damage may be affected by mechanisms independent of H. pylori density or inflammation.. The results are consistent with the hypothesis that tetracycline can decrease inflammation independent of a reduction in the bacterial load. More research is needed to investigate mechanisms leading to epithelial damage which are independent of H. pylori density and inflammation.

Nowadays, microplastics (MPs) exist widely in the marine. The surface has strong adsorption capacity for antibiotics in natural environments, and the cytotoxicity of complex are poorly understood. In the study, 500 nm polystyrene (PS-MPs) and 60 nm nanoplastics (PS-NPs) were synthesized. The adsorption of PS to tetracycline (TC) was studied and their toxicity to gastric cancer cells (AGS) was researched. The adsorption experimental results show that PS absorbing capacity increased with increasing TC concentrations. The defense mechanism results show that 60 nm PS-NPs, 500 nm PS-MPs and their complex induce different damage to AGS cells. Furthermore, 600 mg/L PS-NPs and PS-MPs decline cell viability, induce oxidation stress and cause apoptosis. There is more serious damage of 60 nm PS-NPs than 500 nm PS-MPs in cell viability and intracellular reactive oxygen species (ROS). DNA are also damaged by 60 nm PS-NPs and PS-TC NPs, 500 nm PS-MPs and PS-TC MPs, and 60 nm PS-NPs damage DNA more serious than 500 nm PS-MPs. Moreover, 60 nm PS-NPs and PS-TC NPs seem to promote bcl-2 associated X protein (Bax) overexpression. All treatments provided us with evidence on how PS-NPs, PS-MPs and their compounds damaged AGS cells.

Bisphosphonate, tetracycline and spironolactone use has been shown to increase gastro-oesophageal inflammation, an accepted risk factor for cancer. However, evidence of the effect of these medications on gastro-oesophageal cancer risk are mixed or missing entirely. Therefore, we conducted a nested case-control study using the Primary Care Clinical Information Unit Research (PCCIUR) database from Scotland. Cases with oesophageal or gastric cancer between 1999 and 2011 were matched to up to five controls based on age, gender, year of diagnosis and general practice. Medication use was ascertained using electronic prescribing records. Conditional logistic regression was used to calculate odds ratios (ORs) for the association between medication use and cancer risk after adjustment for comorbidities and other medication use. A similar proportion of gastro-oesophageal cancer cases received bisphosphonates (3.9% vs. 3.5%), tetracycline (6.0% vs. 6.0%) and spironolactone (1.4% vs. 1.1%) compared with the controls. The adjusted ORs for the association between gastro-oesophageal cancer and bisphosphonates, tetracycline and spironolactone were 1.05 (95% CI: 0.85, 1.31), 0.99 (95% CI: 0.84, 1.17) and 1.04 (95% CI: 0.73, 1.49). Further analysis revealed bisphosphonates were associated with increased oesophageal cancer risk (1.34, 95% CI: 1.03, 1.74) but reduced gastric cancer risk (0.71, 95% CI: 0.49, 1.03), although there was no obvious dose-response relationship. Overall, there is little evidence that the use of bisphosphonate, tetracycline or spironolactone is associated with increased risk of gastro-oesophageal cancer. Our findings should reassure GPs and patients that these widely-used medications are safe with respect to gastro-oesophageal cancer risk.

The problem of multidrug-resistant Helicobacter pylori requires new antibiotics development. We have evaluated a potential antibiotics, moenomycin A, which is classified as a phosphoglycolipid antibiotics that targets transglycosylase and is previously thought to be limited in Gram-positive bacteria. Herein, we report the activity of moenomycin A against multidrug-resistant H. pylori and the isolates from patients with different gastrointestinal diseases.

Since the Korean College of Helicobacter and Upper Gastrointestinal Research has first developed the guideline for the diagnosis and treatment of Helicobacter pylori infection in 1998, the revised guideline was proposed in 2009 by the same group. Although the revised guideline was made by comprehensive review of previous articles and consensus of authoritative expert opinions, the evidence-based developmental process was not applied in the revision of the guideline. This new guideline has been revised especially in terms of changes in the indication and treatment of H. pylori infection in Korea, and developed by the adaptation process as evidence-based method; 6 guidelines were retrieved by systematic review and the Appraisal of Guidelines for Research and Evaluation (AGREE) II process, 21 statements were made with grading system and revised by modified Delphi method. After revision, 11 statements for the indication of test and treatment, 4 statements for the diagnosis and 4 statements for the treatment have been developed, respectively. The revised guideline has been reviewed by external experts before the official endorsement, and will be disseminated for usual clinical practice in Korea. Also, the scheduled update and revision of the guideline will be made periodically.

Eleven years has passed since the guideline of the Korean College of Helicobacter and Upper Gastrointestinal Research group for H. pylori infection was produced in 1998. During this period the research for H. pylori has much progressed that H. pylori is now regarded as the major cause of gastric cancer. The seroprevalence of H. pylori in Korea was found to be decreased especially below the age of 40s and in the area of Seoul-Gyeonggi province, and annual reinfection rate of H. pylori has decreased up to 2.94%. In the aspect of diagnostic tests of H. pylori the biopsy is recommended in the body instead of antrum in the subjects with atrophic gastritis and/or intestinal metaplasia for the modified Giemsa staining or Warthin Starry silver staining. The urea breath test is the test of choice to confirm eradication when follow-up endoscopy is not necessary. Definite indication for H. pylori eradication is early gastric cancer in addition to the previous indications of peptic ulcer including scar and Marginal zone B cell lymphoma (MALT type). Treatment is also recommended for the relatives of gastric cancer patient, unexplained iron deficiency anemia, and chronic idiopathic thrombocytopenic purpura. One or two week treatment of proton pump inhibitor (PPI) based triple therapy consisting of one PPI and two antibiotics, clarithromycin and amoxicillin, is recommended as the first line treatment regimen. In the case of treatment failure, one or two weeks of quadruple therapy (PPI+metronidazole+tetracycline+bismuth) is recommended. Herein, Korean College of Helicobacter and Upper Gastrointestinal Research proposes a diagnostic and treatment guideline based on currently available evidence.

The human runt-related transcription factor 3 gene (RUNX3) is considered to be a candidate tumor suppressor gene in gastric carcinoma. However, the role of RUNX3 in the regulation of cell proliferation remains unclear. In the present study, we constructed an adenoviral vector encoding human RUNX3 cDNA under the control of a Tet-responsive promoter (Ad-Tet-FLAG-RUNX3), which regulates the expression of RUNX3 in the presence or absence of doxycycline. A recombinant adenoviral expression vector encoding LacZ (Ad-Tet-LacZ) was used as a negative control. The effect of the transduction of RUNX3 on cell growth was examined using the Tet-On system in a human gastric carcinoma cell line, MKN-1. Exogenous RUNX3 expression was induced successfully by Ad-Tet-FLAG-RUNX3, but not Ad-Tet-LacZ, in the presence of doxycycline in the MKN-1 cells. At 72 h after infection, the proliferative activity in RUNX3-expressing cells was 55% or less of that of the control cells. Flow cytometry revealed that the sub-G(1) peak was increased in cells expressing RUNX3 (34.11%), indicating that the inhibition of cell growth was due to apoptosis, which was confirmed based on Hoechst 33258 staining, the release of cytochrome c from mitochondria into the cytosol, and detection of cleaved caspase-3 by western blotting in MKN-1 cells. Comprehensive analysis using a cDNA microarray showed that RUNX3 upregulated 17 apoptosis-related genes (including FADD, TRAF6, caspase-2, ING1, ING4, Calpain 10, and DNase1) and downregulated 135 apoptosis-related genes (including FLIP, PEA15, TXN2, HSPD1, IKK, and TIAL1) in MKN-1 cells. Pathway analyses to generate functional networks of the genes suggested that promotion of the formation of the death-inducing signaling complex and activation of the mitochondria-mediated pathway were associated with RUNX3-induced apoptosis. In conclusion, our findings suggest that exogenous RUNX3 expression suppressed cell proliferation by inducing apoptosis via the death-receptor mitochondria-mediated pathway in MKN-1 cells.

The impact of Helicobacter eradication therapy on the progression or regression of gastric lesions is poorly defined. This study examined the effects of eradication therapy on inflammation, atrophy, metaplasia, dysplasia, and cancer progression.. C57BL/6 mice were infected with Helicobacter felis and received bacterial eradication therapy after 2, 6, or 12 months of infection. The gastric mucosa was examined at early, mid, and late intervals after eradication and graded for histology, expression pattern of alpha-catenin and beta-catenin, and IQGAP1.. Eradication of Helicobacter infection after 2 or 6 months of infection led to a regression of inflammation, restoration of parietal cell mass, and reestablishment of normal architecture. Progression to adenocarcinoma was prevented. Bacterial eradication at 1 year was associated with the reappearance of parietal cells, partial regression of inflammation, and restoration of architecture. Hyperplasia scores significantly improved, and dysplasia did not progress. Infected mice developed antral adenocarcinoma and gastric outlet obstruction by 24 months. Only 30% of the mice receiving bacterial eradication therapy at 12 months developed antral carcinoma. Bacterial eradication at any time during the first year of infection prevented death due to gastric outlet obstruction. The expression pattern of alpha-catenin, beta-catenin, and IQGAP1 varied with cell type and paralleled histologic changes.. Inflammation, metaplasia, and dysplasia are reversible with early eradication therapy; progression of dysplasia was arrested with eradication therapy given as late as 1 year and prevented gastric cancer-related deaths.

Regression of low-grade B cell gastric lymphoma of mucosa-associated lymphoid tissue after eradication of Helicobacter pylori with antibiotic therapy was recently shown in a small number of patients with low-volume tumors. A patient with a > 10 cm nodular gastric mucosa-associated lymphoid tissue lymphoma that caused hematemesis and weight loss is described. Antibiotic therapy of H. pylori resulted in full clinical recovery and resolution of the mass lesion and morphological features of lymphoma on routine histological examination. However, monotypic immunostaining of plasma cells persisted in a separate and grossly normal-appearing region of the stomach. Antibiotic therapy may be of benefit in patients with mucosa-associated lymphoid tissue lymphoma with mass lesions and significant signs and symptoms, but periodic search for residual lymphoma is needed.

Exfoliative cytology is a useful tool in the differential diagnosis of gastric lesions. The simplified method developed by Klinger and Katz(4) using tetracycline fluorescence was subjected to a critical evaluation. Five cases of gastric carcinoma, two of esophageal carcinoma, 21 of benign peptic ulcer, one case of carcinoma eroding into the bile duct, one case of carcinoma of the pancreas penetrating into the stomach, five normal controls on no medication and two normal controls taking vitamin B(2) were studied. The most apparent drawback of this technique is the number of false negatives encountered in cases of gastric carcinoma (three negative results in five cases of carcinoma). One false-positive test was recorded among 21 patients with benign ulcer. Vitamin B(2) if taken a half hour prior to the test will also produce a false-positive test. It is concluded, therefore, that the tetracycline fluorescence test is inferior to accurate studies of exfoliative cytology.
