Abstract
BACKGROUND First-line therapy does not always provide a high level of Helicobacter pylori eradication due to the increase of H. pylori resistance to antibiotics; therefore, it remains necessary to identify the most effective rescue treatments. The purpose of this study was to evaluate the efficacy and safety of empirical H. pylori furazolidone-containing regimens. MATERIALS AND METHODS Adult H. pylori infected patients empirically treated with furazolidone-containing eradication regimens were registered in an international, prospective, multicenter non-intervention European registry on H. pylori management (Hp-EuReg). Data were collected at AEG-REDCap e-CRF from 2013 to 2021 and the quality was reviewed. Modified intention-to-treat (mITT) effectiveness analyses were performed. RESULTS Overall 106 patients received empirical furazolidone-containing therapy in Russia. Furazolidone was prescribed in a sequential scheme along with amoxicillin, clarithromycin and a proton pump inhibitor in 68 (64%) cases, triple regimens were prescribed in 28 (26%) patients and quadruple regimens in 10 (9.4%). Treatment duration of 7 days was assigned to 2 (1.9%) patients, 10-day eradication therapy in case of 80 (75%) and 14 days - in 24 (23%) patients. Furazolidone was mainly used in first- (79%) and second-line (21%) regimens. The methods used to diagnose H. pylori infection were: histology (81%), stool antigen test (64%), 13C-urea breath test (6.6%), and rapid urease test (1.9%). The mITT effectiveness of sequential therapy was 100%; 93% with the triple therapy and 75.5% with quadruple therapy. Compliance was reported in 98% of cases. Adverse events were revealed in 5.7% of patients, mostly nausea (3.8%). No serious adverse events were reported. CONCLUSION Furazolidone containing eradication regimens appear to be an effective and safe empirical therapy in Russia.

Abstract
BACKGROUND As part of an observational multicenter prospective study European Registry on the management of Helicobacter pylori infection, conducted on the initiative of the European H. pylori and Microbiota Study Group, the compliance of clinical practice in the management of patients with Helicobacter pylori infection in Kazan with clinical guidelines was assessed. MATERIALS AND METHODS The data of 437 patients included into the register by clinical sites in Kazan in 20132019 were analyzed. The methods used for the initial diagnosis of H. pylori infection and eradication control were evaluated. The frequency of various eradication therapy regimens prescription was analyzed in 379 cases. Data regarding the effectiveness of eradication therapy was analyzed in 173 patients. RESULTS The rapid urease test (44.2% of cases) and cytology/histology (60% of cases) were most often used for the initial diagnosis of H. pylori infection; however non-invasive methods such as 13C-urea breath (9.2%), serology (6.2%), H. pylori stool antigen test (2.3%) were less common. In 21.7% of patients two methods of H. pylori detection were used for primary diagnosis. The control test to evaluate the effectiveness of eradication therapy at the recommended timepoint was performed in 46.2% of patients. 13C-urea breath test (31.7%), stool PCR/stool antigen test (28.7%), rapid urease test (22.3%), cytology/histology (26.2% of cases) prevailed in the assessment of eradication rate. Standard triple therapy, including proton pump inhibitor, clarithromycin and amoxicillin was most commonly prescribed as first-line therapy (64.6% of cases). The duration of eradication therapy was 14 days in the majority of cases with pantoprazole as the most common proton pump inhibitor in standard triple therapy regimens (84.8%). The efficacy of 14-day standard triple therapy (mITT) was 87.0%. CONCLUSION The results indicate a high frequency of non-invasive methods use for assessing the effectiveness of eradication therapy; however, the overall rate of eradication efficacy assessment is low, limiting the possibility of analyzing the eradication results. The effectiveness of the most common 14-day standard triple first-line therapy in Kazan doesnt reach the recommended 90% eradication level. This could be explained by high rate of pantoprazole use, which is not an optimal proton pump inhibitor in eradication therapy regimens.

Abstract
AIM European Registry on the management of Helicobacter pylori infection («Hp-EuReg») - a multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group, conducted in 27 European countries in order to evaluate the real clinical practice of diagnosis and treatment of H. pylori and its comparison with international recommendations. MATERIALS AND METHODS The analysis of 2360 patients entered in the register by the Russian centres of «Hp-EuReg» in 2013-2017, who were underwent 1st line eradication therapy. RESULTS The most common methods of primary diagnosis of H. pylori are histological (37.7%), rapid urease test (29.2%) and serology (29.7%). The duration of eradication therapy in 9.4% of cases was 7 days, in 65.3% - 10 days, and in 25.3% - 14 days. To control the effec- tiveness of treatment, H. pylori antigen in feces (31.3%), urea breath test (23.4%) and histological method (23.3%) were used. In 3.6% cases was used serology by mistake. In 17.3% of patients control was not carried out. The effectiveness of triple therapy with a PPI, amoxicillin, clar- ithromycin (per protocol) was 67.6%, with 7-day course, 81.1% at 10-day and 86.7% at 14-day course. Eradication rate of triple therapy with addition of bismuth (per protocol) reached 90,6% in the group receiving 10-day scheme and 93.6% in the group receiving the 14-day treatment. CONCLUSION Significant deviations of clinical practice from expert recommendations, most pronounced at the stage of monitoring the effectiveness of therapy, were noted. The suboptimal efficacy of triple therapy is shown.

Abstract
The multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group (EHMSG) is conducted in 27 countries in Europe. The data from the Russian part of the European registry for the management of Helicobacter pylori infection (European Registry on the management of Helicobacter pylori infection, protocol: "Hp-EuReg") allows us to analyze the real clinical practice of diagnosis and treatment of H. pylori and compare it with international recommendations. MATERIALS AND METHODS A comparative analysis of the data entered in the register by the Russian research centers "Hp-EuReg", in the period from 2013 to 2018, was conducted. RESULTS AND DISCUSSION Invasive diagnostic methods prevail for the primary diagnosis of H. pylori [histology - 20.3% (in 2013 year) - 43.9% (in 2018 year), rapid urease test - 31.7% and 47.8% respectively]. The most popular mode of eradication therapy is a 10-day triple therapy (62.8-76.2%), the effectiveness of which does not exceed 79% (per protocol). Invasive tests (histology) are the leading method for control the effectiveness of therapy, however, there is a tendency towards a wider use of non-invasive methods (H. pylori stool antigen - from 17% in 2013 to 29.3% in 2018 and urea breath test from 6.9 to 18.3%, respectively). Serological test to control the effectiveness of eradication is still used from 8.2% (2013) to 6.1% (2018). Eradication therapy was not performed in 28% of patients throughout the entire observation period. CONCLUSION In Russia, despite approved domestic and international recommendations, deviations in clinical practice persist, both during eradication therapy and in monitoring the effectiveness of eradication therapy.

Abstract
BACKGROUND In humans there are epidemiological data suggesting a protective effect of Helicobacter pylori (H. pylori) infection against the development of autoimmune diseases and in addition, there are laboratory data illustrating H. pylori's ability to induce immune tolerance and limit inflammatory responses. Thus, numerous observational studies have examined the association between H. pylori infection and inflammatory bowel disease (IBD) with various results. OBJECTIVE We performed a meta-analysis of available studies to better define the association of H. pylori infection and IBD. METHODS Medical literature searches for human studies were performed through September 2014, using suitable keywords. In each study the risk ratio (RR) of H. pylori infection in IBD patients vs controls was calculated and pooled estimates were obtained using fixed- or random-effects models as appropriate. Heterogeneity between studies was evaluated using Cochran Q test and I(2) statistics, whereas the likelihood of publication bias was assessed by constructing funnel plots. RESULTS Thirty-three studies were eligible for meta-analysis, including 4400 IBD patients and 4763 controls. Overall 26.5% of IBD patients were positive for H. pylori infection, compared to 44.7% of individuals in the control group. There was significant heterogeneity in the included studies (Q = 137.2, df (Q) =32, I(2) ( )= 77%, p < 0.001) and therefore the random-effects model of meta-analysis was used. The obtained pool RR estimation was 0.62 (95% confidence interval (CI) 0.55-0.71, test for overall effect Z = -7.04, p < 0.001). There was no evidence of publication bias. CONCLUSION The results of this meta-analysis showed a significant negative association between H. pylori infection and IBD that supports a possible protective benefit of H. pylori infection against the development of IBD.

Abstract
BACKGROUND Empiric triple therapy for Helicobacter pylori should be abandoned when clarithromycin resistance rate is >15-20%. Optimisation of triple therapy (high-dose acid suppression and 14-day duration) can increase eradication rates by 10%. AIM To compare the efficacy and safety of optimised triple (OPT-TRI) and nonbismuth quadruple concomitant (OPT-CON) therapies. METHODS Prospective multicentre study in 16 Spanish centres using triple therapy in clinical practice. In a 3-month two-phase fashion, the first 402 patients received an OPT-TRI therapy [esomeprazole (40 mg b.d.), amoxicillin (1 g b.d) and clarithromycin (500 mg b.d) for 14 days] and the last 375 patients an OPT-CON treatment [OPT-TRI therapy plus metronidazole (500 mg b.d)]. RESULTS Seven-hundred seventy-seven consecutive patients were included (402 OPT-TRI, 375 OPT-CON). The OPT-CON therapy achieved significantly higher eradication rates in the per-protocol [82.3% (95% CI = 78-86%) vs. 93.8% (91-96%), P < 0.001] and intention-to-treat analysis [81.3% (78-86%) vs. 90.4% (87-93%), P < 0.001]. Adverse events (97% mild/moderate) were significantly more common with OPT-CON therapy (39% vs. 47%, P = 0.016), but full compliance with therapy was similar between groups (94% vs. 92%, P = 0.4). OPT-CON therapy was the only significant predictor of successful eradication (odds ratio, 2.24; 95% CI: 1.48-3.51, P < 0.001). The rate of participating centres achieving cure rates ≥ 90% favoured OPT-CON therapy (OPT-TRI 25% vs. OPT-CON 62%). CONCLUSIONS Empiric OPT-CON therapy achieved significantly higher cure rates (>90%) compared to OPT-TRI therapy. Addition of metronidazole to OPT-TRI therapy increased eradication rates by 10%, resulting in more mild adverse effects, but without impairing compliance with therapy.

Abstract
BACKGROUND & AIMS Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe. METHODS The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up. RESULTS In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population. CONCLUSION Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

Abstract
BACKGROUND AND AIMS The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). METHODS A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. RESULTS Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p<0.05), the main source was the Internet (92% vs. 88% p=0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p<0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p<0.05). CONCLUSION Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management.

Abstract
BACKGROUND AND AIMS The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients. METHODS The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors. RESULTS A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01). CONCLUSIONS In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

Abstract
INTRODUCTION Helicobacter pylori eradication rates using conventional triple therapies are falling, making viable second-line and rescue regimens necessary. Levofloxacin, tetracycline and rifabutin are three efficacious antibiotics for rescue therapy. AIM We aimed to assess the resistance rates for H. pylori against these antibiotics in an Irish cohort. METHODS Gastric biopsies were collected from 85 patients infected with H. pylori (mean age 46 years) in the Adelaide and Meath Hospital, Dublin in 2008 and 2009. Susceptibility to antibiotics was tested using the Etest. Clinical information was obtained from endoscopy reports and chart review. RESULTS 50.6 % of patients were females. Mean age was 47 years. Ten had prior attempts at eradication therapy with amoxicillin-clarithromycin-PPI, two had levofloxacin-based second-line therapy. 11.7 % [95 % CI (6.5-20.3 %)] (N = 10) had strains resistant to levofloxacin. There were no strains resistant to rifabutin or tetracycline. Levofloxacin resistance in the under 45 age group was 2.6 % (1/38) compared to 19.1 % (9/47) of above 45 age group (p = 0.02). DISCUSSION The levofloxacin rates illustrated in this study are relatively low by European standards and in line with other studies from the United Kingdom and Germany, with younger patients having very low levels of resistance. Levofloxacin, tetracycline and rifabutin are all valid options for H. pylori eradication in Irish patients but the importance of compliance cannot be underestimated.

Abstract
BACKGROUND AND STUDY AIMS The Capsule Endoscopy Crohn's Disease Activity Index (CECDAI or Niv score) was devised to measure mucosal disease activity using video capsule endoscopy (VCE). The aim of the current study was to prospectively validate the use of the scoring system in daily practice. METHODS This was a multicenter, double-blind, prospective, controlled study of VCE videos from 62 consecutive patients with isolated small-bowel Crohn's disease. The CECDAI was designed to evaluate three main parameters of Crohn's disease: inflammation (A), extent of disease (B), and stricture (C), in both the proximal and distal segments of the small bowel. The final score was calculated by adding the two segmental scores: CECDAI = ([A1 × B1] + C1) + ([A2 × B2] + C2). Each examiner in every site interpreted 6 - 10 videos and calculated the CECDAI. The de-identified CD-ROMs were then coded and sent to the principal investigator for CECDAI calculation. RESULTS The cecum was reached in 72 % and 86 % of examinations, and proximal small-bowel involvement was found in 56 % and 62 % of the patients, according to the site investigators and principal investigator, respectively. Significant correlation was demonstrated between the calculation of the CECDAI by the individual site investigators and that performed by the principal investigator. Overall correlation between endoscopists from the different study centers was good, with r = 0.767 (range 0.717 - 0.985; Kappa 0.66; P < 0.001). There was no correlation between the CECDAI and the Crohn's Disease Activity Index or the Inflammatory Bowel Disease Quality of Life Questionnaire or any of their components. CONCLUSION A new scoring system of mucosal injury in Crohn's disease of the small intestine, the CECDAI, was validated. Its use in controlled trials and/or regular follow-up of these patients is advocated.

Abstract
Atrophic gastritis, intestinal metaplasia, and epithelial dysplasia of the stomach are common and are associated with an increased risk for gastric cancer. In the absence of guidelines, there is wide disparity in the management of patients with these premalignant conditions. The European Society of Gastrointestinal Endoscopy (ESGE), the European Helicobacter Study Group (EHSG), the European Society of Pathology (ESP) and the Sociedade Portuguesa de Endoscopia Digestiva (SPED) have therefore combined efforts to develop evidence-based guidelines on the management of patients with precancerous conditions and lesions of the stomach (termed MAPS). A multidisciplinary group of 63 experts from 24 countries developed these recommendations by means of repeat online voting and a meeting in June 2011 in Porto, Portugal. The recommendations emphasize the increased cancer risk in patients with gastric atrophy and metaplasia, and the need for adequate staging in the case of high grade dysplasia, and they focus on treatment and surveillance indications and methods.

Abstract
AIM Ornithine decarboxylase (ODC) is a modifier of adenomatous polyposis coli-dependent tumourigenesis. The G316 > A polymorphism in intron 1 of the ODC gene lies between two myc-binding domains and alters the expression of the gene to affect polyamine metabolism. This variant may be associated with recurrence of colorectal adenoma. We examined whether this variant also modified the susceptibility to sporadic colorectal cancer (CRC). METHOD The G316 > A variant was analysed in a large (n = 754) CRC case-controlled series of hospital patient volunteers (n = 627) in the Czech Republic, and the relationship with cancer risk was estimated by conditional logistic regression. RESULTS After adjusting for age and sex, G316 > A was associated with no decrease in CRC risk for either heterozygotes [odds ratio 0.98, 95% confidence interval (CI) 0.77-1.23] or rare allele homozygotes (odds ratio 0.92, 95% CI 0.61-1.37). CONCLUSION The G316 > A functional variant in the ODC gene is unlikely to make much impact on reducing CRC risk regardless of the reduction in risk found for the recurrence of colorectal adenoma.

Abstract
Gastric adenocarcinoma occurs via a sequence of molecular events known as the Correa’s Cascade which often progresses over many years. Gastritis, typically caused by infection with the bacterium H. pylori, is the first step of the cascade that results in gastric cancer; however, not all cases of gastritis progress along this carcinogenic route. Despite recent antibiotic intervention of H. pylori infections, gastric adenocarcinoma remains the second most common cause of cancer deaths worldwide. Intestinal metaplasia is the next step along the carcinogenic sequence after gastritis and is considered to be a precursor lesion for gastric cancer; however, not all patients with intestinal metaplasia develop adenocarcinoma and little is known about the molecular and genetic events that trigger the progression of intestinal metaplasia into adenocarcinoma. This review aims to highlight the progress to date in the genetic events involved in intestinal-type gastric adenocarcinoma and its precursor lesion, intestinal metaplasia. The use of technologies such as whole genome microarray analysis, immunohistochemical analysis and DNA methylation analysis has allowed an insight into some of the events which occur in intestinal metaplasia and may be involved in carcinogenesis. There is still much that is yet to be discovered surrounding the development of this lesion and how, in many cases, it develops into a state of malignancy.

Abstract
BACKGROUND There is no international agreement on scoring systems used to measure disease activity in ulcerative colitis, nor is there a validated definition for disease remission. AIM To review the principles and components for defining remission in ulcerative colitis and propose a definition that will help improve patient outcomes. METHODS A review of current standards of remission from the perspective of clinical trials, guidelines, clinical practice and patients was conducted by the authors. Selected literature focused on the components of a definition of remission, the utility of a definition and treatment strategies, based on current definitions. RESULTS Different definitions of remission affect the assessment of outcome and make it difficult to compare trials. In the clinic, endoscopy is rarely used to confirm remission, because mucosal healing has only recently begun to be related to the duration of subsequent remission in a way that will affect clinical practice. Histopathology may be the ultimate arbiter of mucosal healing. There is no agreement on the definition of remission in current guidelines. Patient-defined remission may predict endoscopic remission, but has yet to be shown to predict duration of remission. CONCLUSIONS A standard based on clinical symptoms and endoscopy is proposed. Histopathology is a third dimension of remission that may have prognostic value. The definition of remission should help predict long-term outcome. The expectations of patients and their physicians need to be raised, as the goal of treatment of active ulcerative colitis should be to induce remission.

Abstract
Colonoscopic surveillance of hyperplastic polyps alone is controversial and may be inappropriate. The colonoscopy surveillance register at a university teaching hospital was audited to determine the extent of such hyperplastic polyp surveillance. The surveillance endoscopy records were reviewed, those patients with hyperplastic polyps were identified, their clinical records were examined and contact was made with each patient. Of the 483 patients undergoing surveillance for colonic polyps 113 (23%) had hyperplastic polyps alone on last colonoscopy. 104 patients remained after exclusion of those under appropriate surveillance. 87 of the 104 patients (84%) were successfully contacted. 37 patients (8%) were under appropriate colonoscopic surveillance for a significant family history of colorectal carcinoma. 50 (10%) patients with hyperplastic polyps alone and no other clinical indication for colonoscopic surveillance were booked for follow up colonoscopy. This represents not only a budgetary but more importantly a clinical opportunity cost the removal of which could liberate valuable colonoscopy time for more appropriate indications.

Abstract
BACKGROUND In Ireland, colorectal cancer (CRC) is the second most frequently diagnosed cancer in men, after prostate cancer, and the second most frequently diagnosed cancer in women, after breast cancer. By 2020, the number of new cases diagnosed annually in Ireland is projected to have increased by 79% in men and 56% in women. Organised screening for CRC is already underway or is in the process of being rolled out in several European countries, either at a regional or national level. The Adelaide and Meath Hospital/ Trinity College Dublin Colorectal Cancer Screening Programme (TTC-CRC-SP) is Ireland's first pilot population based bowel screening programme. METHOD Based on a biennial test model the pilot aimed to assess the accuracy of FIT and to evaluate the whole programme based on established international key performance indices. RESULTS To date 9,993 individuals aged 50-74 years have been invited to participate in the TTC-CRC-SP with over 5,000 FIT's analysed. Overall uptake was 51% and FIT positivity was 10%. The programme has undertaken over 400 screening colonoscopies and detected 154 precancerous adenomas and 38 cancerous lesions. CONCLUSIONS The first round of The Adelaide and Meath Hospital Tallaght/Trinity College Dublin Colorectal Cancer Screening Programme has been highly successful and confirmed that there is an advantage for FIT based two stage bowel cancer screening programmes.

Abstract
BACKGROUND Forecasting clinical and economic outcomes in ulcerative colitis (UC) and Crohn's disease (CD) patients is complex, but necessary. AIMS To determine: the frequency of treatment-classified clinical states; the probability of transition between states; and the economic outcomes. METHODS Newly diagnosed UC and CD patients, allocated into seven clinical states by medical and surgical treatments recorded in serial 3-month cycles, underwent Markov analysis. RESULTS Over 10 years, 630 UC and 318 CD patients had 22,823 and 11,871 cycles. The most frequent clinical outcomes were medical/surgical remission (medication-free) and mild disease (on 5-aminosalicylates, antibiotics, topical corticosteroids), comprising 28% and 62% of UC cycles and 24% and 51% of CD cycles respectively. The probability of drug-response in patients receiving systemic corticosteroids/immunomodulators was 0.74 in UC, 0.66 in CD. Both diseases had similar likelihood of persistent drug-dependency or drug-refractoriness. Surgery was more probable in CD, 0.20, than UC, 0.08. In terms of economic outcomes, surgery was costlier in UC per cycle, but the outlay over 10 years was greater in CD. Drug-refractory UC and CD cases engendered high costs in the cohort. CONCLUSIONS Most patients on 5-aminosalicylates, corticosteroids and immunomodulators had favourable clinical and economic outcomes over 10 years. Drug-refractory and surgical patients exhibited greater long-term expenses.

Abstract
BACKGROUND Helicobacter pylori infection is eradicated with antimicrobial agents and drug-resistant strains make successful treatment difficult. Geographical variations in virulence-factor genotype also exist. AIM To evaluate prevalence of drug resistance and virulence-factor genotype in Irish H. pylori strains and to investigate if there is any relationship between drug resistance and genotype. METHODS Helicobacter pylori strains isolated from 103 patients were examined. Antimicrobial susceptibilities were tested by Etest. The virulence-factor genotypes were determined using PCR. Frequencies of spontaneous metronidazole-resistance were measured in vitro. RESULTS Metronidazole resistance was present in 37.9% of strains examined. 16.5% of strains were clarithromycin-resistant and resistance to both agents observed was found in 12.6% of strains. 68% of strains were cagA(+). The dominant vacA type was s1/m2, followed by s1/m1 and s2/m2. The metronidazole resistance rate in cagA(-) group was significantly higher than in cagA(+) (P = 0.0089). Spontaneous resistance to metronidazole in cagA(-) occurred in higher frequency when compared with cagA(+). CONCLUSIONS cagA(+) and vacAs1/m2 type was the dominant genotype in Irish H. pylori strains. Significant rates of metronidazole resistance were observed in cagA(-) group. cagA(-) strains tend to acquire metronidazole resistance in vitro. Absence of cagA might be a risk factor in development of metronidazole resistance.

Abstract
BACKGROUND AND AIMS Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. METHODS We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. RESULTS The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. CONCLUSIONS In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

Abstract
BACKGROUND One of the most frequently asked questions during consultation with those affected by inflammatory bowel disease is what are its effects on pregnancy, and how the treatment will impact on conception and pregnancy outcomes. AIM To review available data regarding the safety of biological therapies during pregnancy, primarily in woman with inflammatory bowel disease. METHODS A Medline search was performed and available original research and review articles relating to the use of biological (antitumour necrosis factor-alpha) therapies in inflammatory bowel disease were reviewed. Where information regarding the use of a drug in inflammatory bowel disease during pregnancy was limited, articles referring to its use for other indications, such as rheumatoid arthritis, were reviewed. CONCLUSIONS Based on available data, biological therapies appear to be safe in pregnancy. Most studies looking at the effects of any one medication on pregnancy in inflammatory bowel disease are confounded by the fact that most patients are on multiple medications and have varying levels of disease activity. Stopping therapy in the third trimester should be considered. Large registries with longer follow-up periods will be necessary before firm conclusions about the safety of antitumour necrosis factor-alpha therapies during conception and pregnancy can be drawn.

Abstract
BACKGROUND Contact allergy to a steroid enema leading to worsening of inflammatory bowel disease (IBD) has recently been reported. This study was designed to look for evidence of steroid allergy in patients with IBD. OBJECTIVES To look for the presence of steroid allergy in general, and steroid enema allergy in particular, in a cohort of IBD patients prepared to attend for patch testing. METHODS Patients with IBD in two gastroenterology units at Dublin and Cork were asked to take part in the study. Those who agreed to take part were tested to the British Contact Dermatitis Society standard and steroid batteries. Patients with positive tests to steroids were subsequently asked to attend for intradermal testing with prednisolone, and patch testing to the two commercially available steroid enemas in Ireland and an extended battery of steroids. Reactions were read at days 2 and 4. RESULTS In total, 44 patients from the two units were patch tested. Four patients had positive patch tests to one or more steroids in these batteries: budesonide (n = 2), triamcinolone acetonide (n = 1), tixocortol pivalate (n = 1) and prednisolone (n = 1). Of these, three underwent further testing. All three had positive reactions to intradermal prednisolone and one had a positive test to steroid enema. CONCLUSIONS Four (9%) of our patients were found to have steroid allergy. This has important implications for the local and systemic treatment of their IBD.

Abstract
Colonoscopy is a difficult technique to learn. There are international standards regarding its completion rates. An audit of colonoscopy completion rates was carried out using computerized data in which the compliance with international standards was assessed. Of 909 patients overall crude and adjusted (excluding incompletion due to poor preparation and disease) caecal intubation rates were 88% and 94.1% respectively. Of those who were considered eligible for terminal ileal intubation, the crude and terminal ileal intubation rates were 47.3% and 50.3% respectively. The results indicated completion rated as per recommendations and were adequate for any colon screening programme to be successful.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) affects mainly the young population. The effect of IBD and its treatment on fertility and pregnancy is therefore an important clinical consideration. AIM To review the best management of IBD in the reproductive and pregnant population. METHODS A MEDLINE and an EMBASE search were performed using mainly the search phrases 'pregnancy AND IBD,''sulphasalazine AND male fertility,''abdominal surgery AND female fertility,''AZA AND placenta' and 'infliximab AND pregnancy.' No language or date restrictions were placed. References of review articles were examined. RESULTS Overall male and female fertility are not affected by IBD. Sulphasalzine reduces male fertility. No other drugs used in IBD affect significantly fertility in humans. The risk of pregnancy-related complications and the disease behaviour during pregnancy depends mainly on disease activity at time of conception. Proactive treatment for maintenance of disease remission during gestation is recommended. Except for methotrexate, drugs used in IBD appear safe in pregnancy. Breast feeding should be encouraged. CONCLUSION The management of IBD in the young and pregnant population remains controversial because the literature comes mostly from retrospective studies. Further studies particularly large prospective trials are needed to guide clinicians in decision making.

Abstract
BACKGROUND Guidelines on the management of Helicobacter pylori, which cover indications for management and treatment strategies, were produced in 2000. AIMS To update the guidelines at the European Helicobacter Study Group (EHSG) Third Maastricht Consensus Conference, with emphasis on the potential of H pylori eradication for the prevention of gastric cancer. RESULTS Eradication of H pylori infection is recommended in (a) patients with gastroduodenal diseases such as peptic ulcer disease and low grade gastric, mucosa associated lymphoid tissue (MALT) lymphoma; (b) patients with atrophic gastritis; (c) first degree relatives of patients with gastric cancer; (d) patients with unexplained iron deficiency anaemia; and (e) patients with chronic idiopathic thrombocytopenic purpura. Recurrent abdominal pain in children is not an indication for a "test and treat" strategy if other causes are excluded. Eradication of H pylori infection (a) does not cause gastro-oesophageal reflux disease (GORD) or exacerbate GORD, and (b) may prevent peptic ulcer in patients who are naïve users of non-steroidal anti-inflammatory drugs (NSAIDs). H pylori eradication is less effective than proton pump inhibitor (PPI) treatment in preventing ulcer recurrence in long term NSAID users. In primary care a test and treat strategy using a non-invasive test is recommended in adult patients with persistent dyspepsia under the age of 45. The urea breath test, stool antigen tests, and serological kits with a high accuracy are non-invasive tests which should be used for the diagnosis of H pylori infection. Triple therapy using a PPI with clarithromycin and amoxicillin or metronidazole given twice daily remains the recommended first choice treatment. Bismuth-containing quadruple therapy, if available, is also a first choice treatment option. Rescue treatment should be based on antimicrobial susceptibility. CONCLUSION The global burden of gastric cancer is considerable but varies geographically. Eradication of H pylori infection has the potential to reduce the risk of gastric cancer development.

Abstract
BACKGROUND No previous correlation between phenotype at diagnosis of Crohn's disease (CD) and mortality has been performed. We assessed the predictive value of phenotype at diagnosis on overall and disease related mortality in a European cohort of CD patients. METHODS Overall and disease related mortality were recorded 10 years after diagnosis in a prospectively assembled, uniformly diagnosed European population based inception cohort of 380 CD patients diagnosed between 1991 and 1993. Standardised mortality ratios (SMRs) were calculated for geographic and phenotypic subgroups at diagnosis. RESULTS Thirty seven deaths were observed in the entire cohort whereas 21.5 deaths were expected (SMR 1.85 (95% CI 1.30-2.55)). Mortality risk was significantly increased in both females (SMR 1.93 (95% CI 1.10-3.14)) and males (SMR 1.79 (95% CI 1.11-2.73)). Patients from northern European centres had a significant overall increased mortality risk (SMR 2.04 (95% CI 1.32-3.01)) whereas a tendency towards increased overall mortality risk was also observed in the south (SMR 1.55 (95% CI 0.80-2.70)). Mortality risk was increased in patients with colonic disease location and with inflammatory disease behaviour at diagnosis. Mortality risk was also increased in the age group above 40 years at diagnosis for both total and CD related causes. Excess mortality was mainly due to gastrointestinal causes that were related to CD. CONCLUSIONS This European multinational population based study revealed an increased overall mortality risk in CD patients 10 years after diagnosis, and age above 40 years at diagnosis was found to be the sole factor associated with increased mortality risk.

Abstract
This study determined the relative cost effectiveness of proton pump inhibitor (PPI) based triple therapy regimens for Helicobacter pylori eradication in the primary care setting. Using decision tree analysis the expected cost for each H. pylori eradication strategy was determined from the cost of each treatment option multiplied by the probability of that option occurring. Probabilities were obtained using the GMS prescribing database where all patients who received amoxycillin, clarithromycin and a PPI in the ERHA region in 2002 were followed for one year. Depending on the regimen adopted, 40.8% to 46.1% of patients did not require any further medication in the year following H. pylori eradication treatment. The strategy of rabeprazole, amoxycillin and clarithromycin was the most cost effective option with a cost of Euro466 per asymptomatic patient. Two-way sensitivity analysis indicated that the cost of rabeprazole triple therapy and the duration of rabeprazole maintenance therapy would each have to increase by 30% before this strategy ceased to be the most cost effective and hence best practice option for eradicating Helicobacter pylori in the primary care setting in Ireland.

Abstract
More than 15 years after the launch of omeprazole in 1988, proton-pump inhibitors remain central to the management of acid-suppression disorders and are unchallenged with regard to their efficacy and popularity among doctors and patients. They are considered safe despite early concerns about the possibility of an association with cancer and gastric atrophy; current concerns about long-term proton-pump inhibitor therapy are centred mainly on a possible association with fundic gland polyps and between Helicobacter pylori and gastric atrophic changes. Long-term proton-pump inhibitor usage accounts for the majority of the total proton-pump inhibitor usage. Long-term usage is difficult to define and most patients take proton-pump inhibitors non-continuously. Data indicate that a substantial proportion of long-term users do not have a clear indication for their therapy and there is thus room for reduction or rationalization of treatment. Overall, on-demand therapy is more cost-effective than continuous therapy and should be considered wherever possible.

Abstract
Genetic predisposition to coeliac disease (CD) is determined primarily by alleles at the HLA-DQB locus, and evidence exists implicating other major histocompatibility complex-linked genes (6p21) and the CTLA4 locus on chromosome 2q33. In addition, extensive family studies have provided strong, reproducible evidence for a susceptibility locus on chromosome 5q (CELIAC2). However, the gene responsible has not been identified. We have assayed genetic variation at the IL4, IL5, IL9, IL13, IL17B and NR3C1 (GR) loci, all of which are present on chromosome 5q and have potential or demonstrated involvement in autoimmune and/or inflammatory disease, in a sample of 409 CD cases and 355 controls. Thirteen single nucleotide polymorphisms were chosen on the basis of functional relevance, prior disease association and, where possible, prior knowledge of the haplotype variation present in European populations. There were no statistically significant allele or haplotype frequency differences between cases and controls. Therefore, these results provide no evidence that these loci are associated with CD in this sample population.

Abstract
In addition to the well-established association of coeliac disease (CD) with HLA-DQ (6p21) and possibly CTLA4 (2q33), there is considerable evidence for a susceptibility locus on chromosome 5q, which contains many potential candidates for inflammatory disease, including a cluster of cytokine genes in 5q31. CD cases and controls were genotyped for four single-nucleotide polymorphism (SNP) markers that together characterize >90% of the haplotype variation at the IBD5 locus encoding, among others, the SLC22A4 gene. IBD5 and SLC22A4 map to 5q31 and have recently been associated with Crohn's disease and rheumatoid arthritis. Haplotype frequencies do not differ significantly between CD cases and controls in the Irish population, and therefore the chromosome 5 CD susceptibility locus most likely lies elsewhere on 5q.

Abstract
Colorectal cancer (CRC) is the commonest site for malignancy in Europe. The Commissioner for Health wishes to promote screening for colorectal, breast and cervical cancer in Europe. The aim of this study was to assess public knowledge of CRC in Europe and likely take up of free screening. To this end 20710 members of the public from 21 European countries were interviewed by means of a regular survey amongst consumers (Omnibus survey) using 13 stem questions. Forty-eight per cent thought the population were at equal risk of CRC, only 57% were aware of age and 54% of family history as risk factors. Although 70% were aware of dietary factors, only 30% knew that lack of exercise might be a risk factor. Only 51% had knowledge of CRC screening but 75% were 'very', or 'quite interested, in taking up faecal occult blood (FOB) screening if offered free. Barriers to screening were lack of awareness of risk (31%), youth (22%) and an un-anaesthetic test (19%). There was a big cultural difference in willingness of the public to discuss bowel symptoms: there was a major barrier in Finland (91%), Britain (84%), Luxembourg (82%), Poland (81%) and Portugal (80%); less of a barrier in Spain (49%), Italy (44%) and Iceland (39%). In conclusion, the challenge of achieving high compliance for CRC screening must be a major objective amongst EU member states and non-aligned countries of Europe in the next decade, because it is known that the non-compliant group are those at greatest risk of death from CRC. This study has shown that awareness of CRC is low in Europe and that an educational programme will be essential to achieve high compliance for CRC screening as a means of reducing deaths from bowel cancer.

Abstract
BACKGROUND Heparin has anti-inflammatory and immunomodulatory activity which may be of therapeutic benefit in the treatment of ulcerative colitis. AIM To test whether low molecular weight heparin, given subcutaneously, would provide a significant therapeutic response compared with placebo in the treatment of mild to moderate ulcerative colitis. STUDY DESIGN A prospective, double-blind, randomized, placebo-controlled, multi-centre trial comparing tinzaparin 175 anti-Xa IU/kg/day (innohep, LEO Pharma) subcutaneously for 14 days followed by tinzaparin 4500 anti-Xa IU/day subcutaneously for 28 days with placebo, administered subcutaneously once daily for up to 42 days. The primary outcome measure was the mean change in colitis activity from baseline to the end of study treatment assessed by the sum of scores of stool frequency, rectal bleeding, sigmoidoscopic appearance and histology. Secondary outcome measures included changes in individual activity indices and laboratory parameters. Patients were assessed at weekly intervals for 6 weeks and within 1 week of completing treatment. RESULTS One hundred patients with active ulcerative colitis (up to six bloody stools per day, no fever, no tachycardia or systemic disturbances) were randomized. Forty-eight received tinzaparin and 52 received placebo. The difference in the mean percentage change in colitis activity from baseline to end of treatment (tinzaparin-placebo) was not statistically significant (P = 0.84). There was no difference between tinzaparin and placebo in any secondary outcome measure. One major bleed (rectal), occurred in a patient receiving placebo. CONCLUSION This is the largest trial to date of heparin in ulcerative colitis. The results show no benefit of low molecular weight heparin over placebo in mild to moderately active ulcerative colitis.

Abstract
PURPOSE The identification of groups with a high risk of colorectal adenoma recurrence remains a controversial issue for clinicians. This study was designed to assess the predictive value of initial patient and adenoma characteristics of the three-year recurrence. METHODS The study population was composed of 552 patients with resected colorectal adenomas who completed the European Fiber-Calcium Intervention trial. At both baseline and three-year examinations, the characteristics of adenomas were recorded according to a standardized protocol. The main outcomes measured were the three-year overall recurrence, recurrence of multiple adenomas, recurrence of advanced adenomas (size > or = 1 cm or tubulovillous/villous architecture or moderate/severe dysplasia), and proximal and distal recurrence. RESULTS A three-year recurrence was observed in 122 patients (22.1 percent), and more than one-half of them had recurrent adenomas on the proximal colon. After adjustment for patient characteristics and treatment allocation, the number of adenomas and their proximal location at baseline were the main predictors of recurrence. In comparison with patients who had one or two adenomas on the distal colon, patients with three or more adenomas with at least one of them located on the proximal colon had a much higher risk of overall recurrence (5.3; 95 percent confidence interval, 2.7-10.3), proximal recurrence (8.5; 95 percent confidence interval, 4.1-18), and advanced adenoma recurrence (5.5; 95 percent confidence interval, 2.4-12.6). CONCLUSIONS Follow-up colonoscopies in patients with adenomas should include careful examination of the proximal colon. The time interval between follow-up examinations could probably be extended beyond three years in patients who have only one or two distal adenomas.

Abstract
BACKGROUND The high prevalence of Helicobacter pylori resistance to metronidazole demands treatments more effective than standard bismuth-based triple therapy against these strains. AIM To evaluate the H. pylori eradication rate in both metronidazole-sensitive and -resistant strains following quadruple therapy using single-triple capsules of bismuth biskalcitrate, metronidazole and tetracycline, given with omeprazole. METHODS One hundred and seventy valid patients with duodenal ulcer, gastric ulcer or non-ulcer dyspepsia were treated in eight centres located in five countries. H. pylori was confirmed at baseline using 13C-urea breath test, histology and/or culture. Patients received three single-triple capsules q.i.d. and omeprazole, 20 mg b.d., for 10 days. Each capsule contained bismuth biskalcitrate, 140 mg (as 40 mg Bi2O3 equivalent), metronidazole, 125 mg, and tetracycline, 125 mg. 13C-Urea breath test was repeated at least 4 and 8 weeks post-treatment. RESULTS Overall eradication rates were 93% (158/170) by modified intention-to-treat analysis and 97% (142/146) by per protocol analysis. Eradication rates were 93% (40/43) and 95% (38/40) for strains resistant to metronidazole and 95% (82/86) and 99% (75/76) for strains sensitive to metronidazole by modified intention-to-treat and per protocol analysis, respectively. CONCLUSION This omeprazole-bismuth biskalcitrate-metronidazole-tetracycline 10-day regimen is a very effective and well-tolerated treatment, which overcomes metronidazole resistance.

Abstract
BACKGROUND AND AIMS Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are complex genetic disorders. CARD15/NOD2, a member of the Ced4 superfamily which includes Apaf-1 and CARD4/NOD1, has recently been associated with genetic predisposition to CD but additional genetic factors remain to be identified. Because CARD4/NOD1 shares many structural and functional similarities with CARD15, we tested its putative role in IBD. PATIENTS AND METHODS The 11 exons of CARD4 were screened for the presence of variants in 63 unrelated IBD patients. The only non-private genetic variation encoding for a substitution in the peptidic chain was genotyped in 381 IBD families (235 CD, 58 UC, 81 mixed, and seven indeterminate colitis families) using a polymerase chain reaction-restriction fragment length polymorphism procedure. Genotyping data were analysed by the transmission disequilibrium test. RESULTS Five of nine sequence variations identified in the coding sequence of the gene encoded for non-conservative changes (E266K, D372N, R705Q, T787M, and T787K). Four were present in only one family. The remaining variant (E266K), which exhibited an allele frequency of 0.28, was not associated with CD, UC, or IBD. Furthermore, IBD patients carrying sequence variations in their CARD4 gene had a similar phenotype to those with a normal sequence. CONCLUSION Our results suggest that CARD4 does not play a major role in genetic susceptibility to IBD.
