| 1 | Upper-gastrointestinal bleeding secondary to peptic ulcer disease:Incidence and outcomes显示文摘AIM:To evaluate the incidence,surgery,mortality,and readmission of upper gastrointestinal bleeding(UGIB)secondary to peptic ulcer disease(PUD).METHODS:Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta,Canada from 2004 to 2010(n=7079)using the International Classification of Diseases Codes(ICD-10).A subset of the data was validated using endoscopy reports.Positive predictive value and sensitivity with 95%confidence intervals(CI)were calculated.Incidence of UGIB secondary to PUD was calculated.Logistic regression was used to evaluate surgery,in-hospital mortality,and 30-d readmission to hospital with recurrent UGIB secondary to PUD.Co-variants accounted for in our logistic regression model included:age,sex,area of residence(i.e.,urban vs rural),number of Charlson comorbidities,presence of perforated PUD,undergoing upper endoscopy,year of admission,and interventional radiological attempt at controlling bleeding.A subgroup analysis(n=6356)compared outcomes of patients with gastric ulcers to those with duodenal ulcers.Adjusted estimates are presented as odds ratios(OR)with95%CI.RESULTS:The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were85.2%(95%CI:80.2%-90.2%)and 77.1%(95%CI:69.1%-85.2%),respectively.The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per100000.Overall risk of surgery,in-hospital mortality,and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%,8.5%,and 4.7%,respectively.Interventional radiology to control bleeding was performed in 0.6%of patients and 76%of these patients avoided surgical intervention.Thirty-day readmission significantly increased from 3.1%in 2004 to 5.2%in 2010(OR=1.07;95%CI:1.01-1.14).Rural residents(OR rural vs urban:2.35;95%CI:1.83-3.01)and older individuals(OR≥65 vs<65:1.57;95%CI:1.21-2.04)were at higher odds of being readmitted to hospital.Patients with duodenal ulcers had higher odds of dying(OR=1.27;95%CI:1.05-1.53),requiring surgery(OR=1.73;95%CI:1.34-2.23),and being readmitted to hospital(OR=1.54;95%CI:1.19-1.99)when compared to gastric ulcers.CONCLUSION:UGIB secondary to PUD,particularly duodenal ulcers,was associated with significant morbidity and mortality.Early readmissions increased over time and occurred more commonly in rural areas. | Samuel Quan Alexandra Frolkis Kaylee Milne Natalie Molodecky Hong Yang Elijah Dixon Chad G Ball Robert P Myers Subrata Ghosh Robert Hilsden Sander Veldhuyzen van Zanten Gilaad G Kaplan | 2014 | World Journal of Gastroenterology2014，20，46： | 21 |
| 2 | Covalently closed-circular hepatitis B virus DNA reduction with entecavir or lamivudine显示文摘AIM: To investigate the reduction in hepatitis B virus(HBV) covalently closed-circular DNA(ccc DNA) with entecavir(ETV) or lamivudine(LAM). METHODS: This analysis included patients who had participated in the randomized Phase Ⅲ study ETV-022 comparing ETV vs LAM in nucleos(t)ide-naive, HBe Agpositive patients. Patients received ETV(0.5 mg daily) or LAM(100 mg daily) for a minimum of 52 wk. Patients were eligible to participate in this sub-study if they had paired biopsies at baseline and week 48 with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA. The main objective was to compare changes in hepatic HBV ccc DNA and total hepatic HBV DNA at week 48 of ETV or LAM treatment, which was a secondary endpoint of study ETV-022. Additional post hoc analyses included linear regression analyses to assess associations of baseline levels and on-treatment changes of ccc DNA with other baseline factors [sex,age, serum HBV DNA, alanine aminotransferase(ALT), Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBV genotype], or ontreatment factors(changes from baseline at week 48 in serum HBV DNA, ALT, Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBe Ag loss at week 48).RESULTS: Overall, 305 patients(ETV = 159; LAM = 146) of ETV-022 had paired baseline and week 48 liver biopsies with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA, and were included in this analysis. Baseline demographics and disease characteristics were comparable between the two arms. After 48 wk, ETV resulted in significantly greater reductions in hepatic HBV ccc DNA [-0.9 log10 copies/human genome equivalent(HGEq) vs-0.7 log10 copies/HGEq; P = 0.0033] and total hepatic DNA levels(-2.1 log10 copies/HGEq vs-1.6 log10 copies/HGEq; P < 0.0001) than LAM. Virologic, biochemical, and histologic response rates at week 48 were also greater with ETV than with LAM. Baseline HBV ccc DNA levels were positively associated with baseline levels of serum HBV DNA and total hepatic HBV DNA, and negatively associated with HBV genotype F. On-treatment changes in HBV ccc DNA levels were negatively associated with baseline levels of serum HBV DNA and baseline ALT, and were positively associated with on-treatment changes in the levels of serum HBV DNA, total hepatic HBV DNA levels, and ALT, change in Knodell necroinflammatory score, and HBe Ag loss.CONCLUSION: Forty-eight weeks of ETV resulted in greater reductions in ccc DNA and total hepatic HBV DNA than LAM, but long-term therapy may be needed for ccc DNA elimination. | Scott Bowden Stephen Locarnini Ting-Tsung Chang You-Chen Chao Kwang-Hyub Han Robert G Gish Robert A de Man Miao Yu Cyril Llamoso Hong Tang | 2015 | World Journal of Gastroenterology2015，21，15： | 11 |
| 3 | Anti-hepatitis C virus potency of a new autophagy inhibitor using human liver slices model显示文摘AIM: To evaluate the antiviral potency of a new antihepatitis C virus(HCV) antiviral agent targeting the cellular autophagy machinery. METHODS: Non-infected liver slices, obtained from human liver resection and cut in 350 μm-thick slices(2.7 × 106 cells per slice) were infected with cell culture-grown HCV Con1b/C3 supernatant(multiplicity of infection = 0.1) cultivated for up to ten days. HCV infected slices were treated at day 4 post-infection with GNS-396 for 6 d at different concentrations. HCV replication was evaluated by strand-specific real-time quantitative reverse transcription- polymerase chain reaction. The infectivity titers of supernatants were evaluated by foci formation upon inoculation into naive Huh-7.5.1 cells. The cytotoxic effect of the drugs was evaluated by lactate dehydrogenase leakage assays. RESULTS: The antiviral efficacy of a new antiviral drug, GNS-396, an autophagy inhibitor, on HCV infection of adult human liver slices was evidenced in a dosedependent manner. At day 6 post-treatment, GNS-396 EC50 was 158 nmol/L without cytotoxic effect(compared to hydroxychloroquine EC50 = 1.17 μmol/L).CONCLUSION: Our results demonstrated that our ex vivo model is efficient for evaluation the potency of autophagy inhibitors, in particular a new quinoline derivative GNS-396 as antiviral could inhibit HCV infection in a dosedependent manner without cytotoxic effect. | Sylvie Lagaye Sonia Brun Jesintha Gaston Hong Shen Ruzena Stranska Claire Camus Clarisse Dubray Géraldine Rousseau Pierre-Philippe Massault Jerome Courcambeck Firas Bassisi Philippe Halfon Stanislas Pol | 2016 | World Journal of Hepatology2016，8，21： | 5 |
| 4 | Screening Helicobacter pylori genes induced during infection of mouse stomachs显示文摘AIM:To investigate the effect of in vivo environment on gene expression in Helicobacter pylori(H.pylori) as it relates to its survival in the host.METHODS:In vivo expression technology(IVET) systems are used to identify microbial virulence genes.We modified the IVET-transcriptional fusion vector,pIVET8,which uses antibiotic resistance as the basis for selection of candidate genes in host tissues to develop two unique IVET-promoter-screening vectors,pIVET11 and pIVET12.Our novel IVET systems were developed by the fusion of random Sau3A DNA fragments of H.pylori and a tandem-reporter system of chloramphenicol acetyltransferase and beta-galactosidase.Additionally,each vector contains a kanamycin resistance gene.We used a mouse macrophage cell line,RAW 264.7 and mice,as selective media to identify specific genes that H.pylori expresses in vivo.Gene expression studies were conducted by infecting RAW 264.7 cells with H.pylori.This was followed by real time polymerase chain reaction(PCR) analysis to determine the relative expression levels of in vivo induced genes.RESULTS:In this study,we have identified 31 in vivo induced(ivi) genes in the initial screens.These 31 genes belong to several functional gene families,including several well-known virulence factors that are expressed by the bacterium in infected mouse stomachs.Virulence factors,vacA and cagA,were found in this screen and are known to play important roles in H.pylori infection,colonization and pathogenesis.Their detection validates the efficacy of these screening systems.Some of the identified ivi genes have already been implicated to play an important role in the pathogenesis of H.pylori and other bacterial pathogens such as Escherichia coli and Vibrio cholerae.Transcription profiles of allivi genes were confirmed by real time PCR analysis of H.pylori RNA isolated from H.pylori infected RAW 264.7 macrophages.We compared the expression profile of H.pylori and RAW 264.7 coculture with that of H.pylori only.Some genes such as cag A,vac A,lpx C,mur I,tlp C,trx B,sod B,tnp B,pgi,rbf A and inf B showed a 2-20 fold upregulation.Statistically significant upregulation was obtained for all the above mentioned genes(P < 0.05).tlp C,cag A,vac A,sod B,rbf A,inf B,tnp B,lpx C and mur I were also significantly upregulated(P < 0.01).These data suggest a strong correlation between results obtained in vitro in the macrophage cell line and in the intact animal.CONCLUSION:The positive identification of these genes demonstrates that our IVET systems are powerful tools for studying H.pylori gene expression in the host environment. | Aparna Singh Nathaniel Hodgson Ming Yan Jungsoo Joo Lei Gu Hong Sang Emmalena Gregory-Bryson William G Wood Yisheng Ni Kimberly Smith Sharon H Jackson William G Coleman | 2012 | World Journal of Gastroenterology2012，18，32： | 5 |

| 9 | Clinical predictors of thiopurine-related adverse events in Crohn's disease显示文摘AIM: To determine the incidence and predictors of thiopurine-related adverse events. METHODS: Subjects with Crohn's disease who were followed in the Alberta Inflammatory Bowel Disease Consortium patient database registry were identified. Retrospective chart review was conducted between August 5th, 2010 and June 1st, 2012. We collected data on: age at diagnosis; sex; disease location and behaviour at time of prescribing thiopurine; perianal fistulising disease at or prior to thiopurine prescription; smoking status at time of thiopurine prescription, use of corticosteroid within 6 mo of diagnosis; dosage, age at onset, and cessation of 5-aminosalicyclic acid(5-ASA); anti-tumour necrosis factor medication exposure and intestinal resection before thiopurine prescription. The primary outcome of interest was the first adverse event that led to discontinuation of the first thiopurine medication used. Logistic regression models were used to associate clinical characteristics with outcomes after adjusting for potential confounders. Risk estimates were presented as odds ratios(OR) with 95% CI. Effect modification by age and sex were explored.RESULTS: Our cohort had a median follow-up duration of 5.8 years [interquartile range(IQR 25th-75th) 2.7-9.1]. Thiopurine therapy was discontinued in 31.3% of patients because of: hypersensitivity reactions(7.1%), acute pancreatitis(6.2%), gastrointestinal intolerance(5.4%), leucopenia(3.7%), hepatotoxicity(3.4%), infection(1.1%) and other reasons(4.3%). A higher incidence of thiopurine withdrawal was observed in patients over the age of 40(39.4%, P = 0.007). A sexby-age interaction(P = 0.04) was observed. Females older than 40 years of age had an increased risk of thiopurine discontinuation due to an adverse event(age above 40 vs age below 40, adjusted OR = 2.8; 95%CI: 1.4-5.6). In contrast, age did not influence thiopurine withdrawal in males(age above 40 vs below 40, adjusted OR = 0.9; 95%CI: 0.4-2.1). Other clinical variables(disease location and phenotype, perianal disease, smoking history, history of intestinal resection and prior 5-ASA or corticosteroid use) were not associated with an increased risk an adverse event leading to therapy cessation. CONCLUSION: Thiopurine withdrawal due to adverse events is commoner in women over the age of 40 at prescription. These findings need to be replicated in other cohorts. | Gordon W Moran Marie-France Dubeau Gilaad G Kaplan Hong Yang Bertus Eksteen Subrata Ghosh Remo Panaccione | 2015 | World Journal of Gastroenterology2015，21，25： | 2 |
