Abstract
Background and study aims COVID-19 has dramatically impacted endoscopy practice because upper endoscopy procedures can be aerosol-generating. Most elective procedures have been rescheduled. Endoscopic retrograde cholangiopancreatography (ERCP) is frequently performed in emergency or urgent settings in which rescheduling is not possible. We evaluated the impact of the COVID-19 pandemic on ERCP in Italy during the SARS-CoV-2 lockdown, in areas with high incidence of COVID-19. Patients and methods We performed a retrospective survey of centers performing ERCP in high COVID-19 prevalence areas in Italy to collect information regarding clinical data from patients undergoing ERCP, staff, case-volume and organization of endoscopy units from March 8, 2020 to April 30, 2020. Results We collected data from 31 centers and 804 patients. All centers adopted a triage and/or screening protocol for SARS-CoV-2 and performed follow-up of patients 2 weeks after the procedure. ERCP case-volume was reduced by 44.1 % compared to the respective 2019 timeframe. Of the 804 patients undergoing ERCP, 22 (2.7 %) were positive for COVID-19. Adverse events occurred at a similar rate to previously published data. Of the patients, endoscopists, and nurses, 1.6 %, 11.7 %, and 4.9 %, respectively, tested positive for SARS-CoV-2 at follow up. Only 38.7 % of centers had access to a negative-pressure room for ERCP. Conclusion The case-volume reduction for ERCP during lockdown was lower than for other gastrointestinal endoscopy procedures. No definitive conclusions can be drawn about the percentage of SARS-CoV-2-positive patients and healthcare workers observed after ERCP. Appropriate triage and screening of patients and adherence to society recommendations are paramount.

Abstract
AIM: To investigate the level of mucosal expression and the involvement of the receptor for the advanced glycation end products (RAGE) in delayed apoptosis and tumor necrosis factor (TNF)-α production in Crohn’s disease (CD).
METHODS: Surgical and endoscopic specimens from both inflamed and non-inflamed areas of the ileum and/or colon were collected from 20 and 14 adult CD patients, respectively, and used for the assessment of RAGE expression by means of immunohistochemistry and western blotting analysis. Normal tissues from 21 control subjects were used for comparison. The same polyclonal anti-human RAGE antibody (R and D System) was used in all experimental conditions. RAGE staining was quantized by a score including both the amount of positive cells and intensity of immunoreactivity; cellular pattern was also described. The effects of RAGE blocking on apoptotic rate and TNF-α production were investigated on immune cells freshly isolated from CD mucosa and incubated both with and without the muramyl dipeptide used as antigenic stimulus. Statistical analysis was performed via the test for trend, with regression models to account for intra-patient correlations. A 2-sided P < 0.05 was considered significant.
RESULTS: In inflamed areas, RAGE expression in both the epithelial and lamina propria compartments was higher than control tissues (P = 0.001 and 0.021, respectively), and a cluster of positive cells were usually found in proximity of ulcerative lesions. Similar results were obtained in the lamina propria compartment of non-inflamed areas (P = 0.025). The pattern of staining was membranous and granular cytosolic at the epithelial level, while in the lamina propria it was diffuse cytosolic. When evaluating the amount of protein expression by immunoblotting, a significant increase of both surface area and band intensity (P < 0.0001 for both) was observed in CD inflamed areas compared to control tissue, while in non-inflamed areas a significant increase was found only for band intensity (P < 0.005). Moreover, a significantly lower expression in non-inflamed areas in comparison with inflamed areas was found for both surface area and band intensity (P < 0.0006 for both). Finally, RAGE blocking largely affects both the apoptotic rate of mucosal cells (towards an increase in both non-inflamed and inflamed areas of P < 0.001 and < 0.0001, respectively) and TNF-α secretion (towards a decrease in both non-inflamed and inflamed areas of P < 0.05 and < 0.01, respectively), mainly in the presence of antigenic stimulation.
CONCLUSION: RAGE is up-regulated in CD, especially in inflamed areas, and it appears to play a role in the mechanisms involved in chronic inflammation.

Abstract
BACKGROUND Health-related quality of life is an important measure of treatment outcome; its evaluation requires the use of internationally validated ad hoc questionnaires. The McMaster Inflammatory Bowel Disease Questionnaire (IBDQ) is the most used specific instrument. AIM To assess the validity and reliability of the Italian translation of the IBDQ. METHODS The IBDQ underwent forward and backward translation; 13 patients were enrolled for cognitive testing of the Italian version to increase clarity. For field testing, 113 patients (65 with Crohn's disease and 48 with ulcerative colitis) completed both the IBDQ and the generic instrument 36-item Short Form Health Survey scale (SF-36). RESULTS Data quality was optimal with high completeness and low floor and ceiling effect. Item internal consistency was satisfied for 100% of patients, while discriminant validity showed a few items with higher correlations with other scales. Cronbach's alpha coefficient was 0.96. Test-retest correlations indicated good reliability (Pearson R 0.81). Exploratory factor analysis indicated that the original grouping of the item was suboptimal. The score proved sensitive to disease activity, gender and quality of life as measured by the SF-36. CONCLUSIONS The Italian translation of the McMaster Inflammatory Bowel Disease Questionnaire sounds natural and is easy to understand. A field test gave results comparable to other international validations, supporting its use in cross-national surveys.

Abstract
INTRODUCTION Colonoscopy is a necessary tool in the management of Crohn's disease, but the benefit achieved by the procedure is a matter of debate. In the present study we evaluate the clinical impact of performing colonoscopy in Crohn's disease patients. METHODS Consecutive patients with Crohn's disease undergoing colonoscopy were considered. The following issues were considered: appropriateness of indications; relevant findings able to change the management of the patients; the endoscopist's management decisions based on patient's clinical picture, i.e. increased, maintained or decreased treatment, compared with those selected after performing endoscopy. RESULTS 204 patients (116 male/88 female, mean age 41 years) were included. Colonoscopy was judged indicated in 52.9% cases, according to current guidelines. In 54% of patients, endoscopy revealed a significant lesion, and this rate was significantly lower for non-indicated procedures (25.9%, p<0.0001). The endoscopic findings were in disagreement with symptoms in about 25% of cases, but the impact of the endoscopic findings on the endoscopist's decision was likely to be very small without any differences between appropriate and inappropriate procedures. CONCLUSIONS Endoscopy is a potent tool in the management of Crohn's disease, if correctly used, but in the majority of cases a correct therapeutic decision may be established simply on the basis of clinical picture and non-invasive markers, whilst relevant endoscopic findings have a relatively low impact on the medical treatment.

Abstract
BACKGROUND AND STUDY AIMS Capsule endoscopy is considered the diagnostic procedure of choice in patients with obscure gastrointestinal bleeding (OGIB). Double-balloon endoscopy (DBE) offers both diagnostic and therapeutic potential, but is invasive, complex, and time-consuming. The aim was to evaluate diagnostic agreement between capsule endoscopy and DBE in patients with OGIB, and secondarily the diagnostic gain of DBE when capsule endoscopy detected only blood or clots in the small-bowel lumen. METHODS Multicenter prospective study carried out at six institutions in Italy. RESULTS 193 patients (119 men, mean age 61.6 +/- 16.2) first underwent capsule endoscopy and then DBE. The most frequent positive findings at capsule endoscopy were vascular lesions (74 patients, 38.3 %), blood or clot in the lumen (34, 17.6 %), and tumor mass (20, 10.4 %). The most frequent findings at DBE were vascular lesions (72 patients, 37.3 %), neoplasia (30, 15.5 %) and ulcers/inflammatory lesions (12, 6.2 %). Overall kappa coefficient was 0.46 (95 %CI 0.38 - 0.54), with maximum concordance for vascular (0.72 [95 %CI 0.59 - 0.84]) and inflammatory (0.78 [0.58 - 0.99]) lesions and minimum for polyps (0.46 [0.16 - 0.80]). Blood in the lumen was the only positive finding at capsule endoscopy in 34 cases; of these, 12 had negative DBE findings whereas 10 had vascular lesions, 6 neoplasia, 1 ulcer, and 5 diverticula. CONCLUSION Capsule endoscopy and DBE have good agreement for vascular and inflammatory lesions but not for polyps or neoplasia. DBE provides valuable adjunctive information, particularly in patients with neoplasia or polyp at capsule endoscopy. DBE clarified the origin of bleeding in two-thirds of patients with capsule endoscopy showing only blood in the lumen.

Abstract
BACKGROUND Double-balloon enteroscopy (DBE) is theoretically useful in Crohn's disease (CD) since it is potentially able to investigate the whole small intestine, but sparse data are available. AIM To assess the feasibility, safety, and diagnostic yield of DBE in CD. METHODS The study was conducted in a tertiary care centre for inflammatory bowel disease. Thirty-seven patients with CD (18/19 male/female, mean age 42 years, range 13-77 years) were considered. Thirty-two DBEs from the oral approach and 18 from the anal (in 6 patients from both ways with a complete exploration in 4, 10.8%) were performed. Indications were: first diagnosis/staging in 16 cases, diagnosis of stenosis in 7, obscure bleeding in 10, suspected neoplasia in 2, and postsurgical evaluation in 2. One hundred and thirty-three other procedures (3.7 per patient) were performed with the same indication. RESULTS Insertion depth from the oral route was 266.5 ± 100 cm and from the anal route 72.5 ± 60 cm. Ileocecal valve was passed in 8/13 patients, but in 4 DBE explored less than 50 cm of ileum. Diagnostic yield was 59.4% but changed according to indication (40% in obscure bleeding, 100% in case of strictures) and was higher when DBE was conducted on the basis of previous investigations (77.8% versus 40%, p = 0.037). CONCLUSION DBE is a feasible, useful, but technically demanding method in CD. Definition of the proper introduction route by means of previous investigations is associated with a higher efficacy of DBE.

Abstract
BACKGROUND Colonoscopy is frequently performed in ulcerative colitis (UC), but its benefit in the management of the disease is a matter of debate. The objective was to determine the clinical impact of colonoscopy in UC. METHODS Consecutive patients with UC undergoing colonoscopy were studied. The design and main outcome measurement was appropriateness of indications, evaluated according to guidelines. Endoscopic findings altering the management of the patients were registered. The endoscopist's management decisions based on patient's clinical picture were compared with those selected after endoscopy. Need for further investigations was recorded. Endpoints for colonoscopy-improving management were prospectively defined: change in medical therapy, need for adjunctive procedures, identification or exclusion of cancer, adenomatous polyps, or other conditions with clinical impact. The setting was an open access endoscopy service in a tertiary care center. RESULTS In all, 507 patients (268 male, 239 female, mean age 42 years) were included. Colonoscopy was indicated in 60.8% of cases. In 46% of patients endoscopy revealed a significant lesion; this rate was higher for indicated (67.2) than for not indicated procedures (13.5%, P < 0.0001). The endoscopist's decision was altered by the endoscopic finding in 7.6% of cases and was not different between appropriate and inappropriate procedures. CONCLUSIONS Endoscopy is a potent tool in the management of UC if correctly used. However, in the majority of cases a correct therapeutic decision may be established simply on the basis of the clinical picture. Relevant endoscopic findings have a relatively low impact on the medical treatment, but may have a very important value in the prognostic assessment of the disease.

Abstract
BACKGROUND AND AIMS There are limited evidence based data concerning the use of azathioprine in ulcerative colitis. We aimed to compare the efficacy of azathioprine and oral 5-aminosalicylic acid in inducing remission of steroid dependent ulcerative colitis. METHODS Seventy two patients with steroid dependent ulcerative colitis were admitted to this investigator-blind study. Steroid dependence was defined as a requirement for steroid therapy > or =10 mg/day during the preceding six months, with at least two attempts to discontinue the medication. The disease had to be clinically and endoscopically active at study entry, and all patients were taking systemic prednisolone (40 mg/day). Patients were randomised to receive azathioprine 2 mg/kg/day or oral 5-aminosalicylic acid 3.2 g/day, for a six month follow up period. The outcome of the treatment was defined as (1) success, indicating induction of clinical and endoscopic remission and steroid discontinuation, or (2) failure, indicating the absence of clinical and endoscopic remission and therefore the need for at least one further cycle of systemic steroids to control symptoms, apart from the initial one, or colectomy. RESULTS Significantly more patients in the azathioprine than in the 5-aminosalicylic acid group had clinical and endoscopic remission, and discontinued steroid therapy, both in the intention to treat (azathioprine v 5-aminosalicylic acid: 19/36 patients (53%) v 7/36 (21%); odds ratio (OR) 4.78 (95% confidence interval (CI) 1.57-14.5)) and per protocol (azathioprine v 5-aminosalicylic acid: 19/33 patients (58%) v 7/34 (21%); OR 5.26 (95% CI 1.59-18.1)) analysis. CONCLUSIONS Azathioprine is significantly more effective than 5-aminosalicylic acid in inducing clinical and endoscopic remission and avoiding steroid requirement in the treatment of steroid dependent ulcerative colitis.

They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered. RESULTS Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience. Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8+/-0.6 vs 3.0+/-1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy. On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy. CONCLUSION Endoscopist's experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis.

Abstract
BACKGROUND & AIMS Because the reoperation rate for Crohn's disease is high after resective surgery, use of conservative surgery has increased. Mesalamine was investigated for the prevention of postoperative relapse, with disappointing results. The role of azathioprine in the postoperative setting is unknown. We aimed to compare the efficacy and safety of azathioprine and mesalamine in the prevention of clinical and surgical relapse in patients who have undergone conservative surgery for Crohn's disease. METHODS In a prospective, open-label, randomized study, 142 patients received azathioprine (2 mg. kg -1. day -1 ) or mesalamine (3 g/day) for 24 months. Clinical relapse was defined as the presence of symptoms with a Crohn's Disease Activity Index score >200 and surgical relapse as the presence of symptoms refractory to medical treatment or complications requiring surgery. RESULTS After 24 months, the risk of clinical relapse was comparable in the azathioprine and mesalamine groups, both on intention-to-treat (odds ratio [OR], 2.04; 95% confidence interval [CI], 0.89-4.67) and per-protocol analyses (OR, 1.79; 95% CI, 0.80-3.97). No difference was observed with respect to surgical relapse at 24 months between the 2 groups. In a subgroup analysis, azathioprine was more effective than mesalamine in preventing clinical relapse in patients with previous intestinal resections (OR, 4.83; 95% CI, 1.47-15.8). More patients receiving azathioprine withdrew from treatment due to adverse events than those receiving mesalamine (22% vs. 8%; P = 0.04). CONCLUSIONS While no difference was observed in the efficacy of azathioprine and mesalamine in preventing clinical and surgical relapses after conservative surgery, azathioprine is more effective in those patients who have undergone previous intestinal resection.

Abstract
Crohns Disease (CD) is a chronic intestinal inflammatory disease of unknown origins that cannot be definitely resolved with surgical intervention. Therefore, pharmacologic therapies are of great importance both in preventing relapses and by determining remissions. In this paper the authors analyse the different drugs available for the treatment of Crohns disease, and focus on their efficacy and tollerability.

Abstract
BACKGROUND AND AIMS The efficacy of azathioprine in the treatment of chronic active Crohn's disease is well established. However, this drug has a long onset of action. Methotrexate has also been shown to be effective in chronic active Crohn's disease. The aim of this study was to evaluate the efficacy and safety of methotrexate in comparison with azathioprine, and to establish whether methotrexate has a shorter onset of action in this setting. METHODS Patients with chronic active Crohn's disease were admitted to this investigator-blind study. Chronicity was defined as the need for steroid therapy of > or = 10 mg/day for at least 4 months during the preceding 12 months, with at least one attempt to discontinue treatment. The disease had to be clinically active at entry, with a Crohn's Disease Activity Index of > or = 200. Six patients treated with azathioprine and methotrexate, respectively, were found to have enterocutaneous and perianal fistulas. At entry, all patients received prednisolone (40 mg once a day) which was tapered over a period of 12 weeks unless their clinical condition deteriorated. All patients were randomised to receive i.v. methotrexate 25 mg/week, or oral azathioprine 2 mg/kg per day, for a 6-month follow-up period. After the first 3 months, methotrexate was switched to oral administration maintaining the same dose. The primary efficacy outcome considered was the proportion of patients entering first remission after 3 and 6 months of therapy. Clinical remission was defined as the lack of need for steroid treatment and a Crohn's Disease Activity Index score of < or = 150 points at each scheduled visit. RESULTS In the 54 patients (26 F, 28 M, mean age 34 years, range 18-60) randomly assigned to methotrexate (n=27) or azathioprine (n=27), no statistically significant difference was found between the two treatment regimens with respect to remission rate after 3 (methotrexate 44%, azathioprine 33%, p=0.28, (95% CI, 0.369-0.147), and 6 months (methotrexate 56%, azathioprine 63%, p=0.39, 95% CI, 0.187-0.335), respectively. Six patients withdrew from therapy due to adverse events: 3/27 (11%) in methotrexate and 3/27 (11%) in azathioprine. Drug-related adverse events (asthenia, nausea and vomiting) that did not require withdrawal from therapy were more frequent in the methotrexate group (azathioprine: 2/27 (7%); methotrexate: 12/27 (44%), p=0.00009). The frequency of these adverse events was comparable during the intravenous or oral administration of the drug. CONCLUSIONS This study confirms that methotrexate is effective in inducing remission in patients with chronic active Crohn's disease, therapeutic efficacy being comparable, but not faster, than that of azathioprine.

Abstract
BACKGROUND Proton pump inhibitors may interfere with the accuracy of the (13)C-urea breath test, but little information is available on the effect of standard doses of various proton pump inhibitors on this test. AIM To evaluate the effect of short-term standard doses of omeprazole, lansoprazole and pantoprazole on the accuracy of the standardized (13)C-urea breath test. METHODS A total of 124 patients with Helicobacter pylori infection, diagnosed on the basis of gastric histology, rapid urease test and (13)C-urea breath test, were studied. These patients received omeprazole, 20 mg/day, lansoprazole, 30 mg/day, or pantoprazole, 40 mg/day, for 2 weeks according to a randomized protocol. (13)C-Urea breath test was repeated on days 4, 7 and 14 while on therapy and 7 days after proton pump inhibitor withdrawal. RESULTS Of the patients receiving omeprazole and lansoprazole, 30% (12/40) and 20% (8/41), respectively, became (13)C-urea breath test negative during therapy, compared with none of the 42 patients treated with pantoprazole (P < 0.05). All the false negative (13)C-urea breath test results returned to positive within 1 week of drug withdrawal, with a mean recovery to 84.7 +/- 15.6% of baseline delta(13)CO(2). CONCLUSIONS Short-term omeprazole and lansoprazole interfere with the 13C-urea breath test, although a return to positive test results invariably occurs within 1 week of proton pump inhibitor withdrawal. In contrast, the accuracy of the (13)C-urea breath test does not appear to be significantly impaired by short-term pantoprazole, which therefore may not necessarily be withdrawn before this test.

Abstract
BACKGROUND Although the association between Helicobacter pylori infection and gastric autoimmunity is now well established, to date little is known about the significance of anticanalicular autoantibodies in patients with duodenal ulcer (DU). We therefore investigated the prevalence of serum antiparietal cell autoreactivity in DU patients as well as the relationship between these autoantibodies, gastric histopathology and gastric secretory function in this setting. METHODS Forty-one consecutive patients with H. pylori-positive DU were initially recruited. In all patients, basal (BAO) and pentagastrin stimulated acid output (PAO), fasting and meal-induced serum gastrin levels, as well as serum pepsinogen I concentrations, were measured. Antral and body gastritis was evaluated according to the Sydney system. Serum anticanalicular autoreactivity was determined by the indirect immunoperoxidase technique. RESULTS Serum anticanalicular autoantibodies were found in 7 out of 34 patients (20%). The presence of these antibodies was associated with a significantly higher grade of body gastritis (activity: 1.9 versus 0.9) as well as with significantly higher fasting and meal stimulated gastrin levels (mean fasting gastrin, 76.4 (15.2) microg/ml versus 59.3 (20.5) microg/ml). In addition, PAO values were significantly lower in patients with gastric autoantibodies than in those without this autoreactivity (mean 0.35 (0.16) mmol kg(-1)h(-1) versus 0.49 (0.16)mmol kg(-1)h(-1)). In contrast, no significant differences were found between patients with and without anticanalicular autoantibodies as regards fasting serum pepsinogen I concentrations. CONCLUSIONS Serum anticanalicular autoantibodies can be detected in 20% of patients with DU and are associated with a more severe pattern of body gastritis, higher gastrin levels and decreased peak acid secretion values. Their presence could account for the normal or reduced acid output which can be seen in a subset of DU patients.

Abstract
OBJECTIVES Seven-day proton pump inhibitor (PPI)-based triple therapies are the first-line anti-Helicobacter pylori regimens; to date, however, there is still no agreement concerning all the predictors of H. pylori cure under these regimens. The aim of this prospective study was to evaluate whether patients with certain pretreatment characteristics may benefit from an extension from 1 to 2 wk of treatment with lansoprazole, amoxycillin, and clarithromycin. METHODS A total of 142 patients with H. pylori infection ascertained by means of gastric histopathology and 13C urea breath test (UBT) participated in this study. In all patients H. pylori density was determined at histology both on antral and corpus biopsies, and H. pylori culture with antibiotic susceptibility testing; IgG anti-H. pylori titers were also determined before therapy. Patients were randomized to receive 1-wk versus 2-wk of treatment with lansoprazole (30 mg b.i.d.), clarithromycin (500 mg b.i.d.), and amoxycillin (1 g b.i.d.). The association between eradication and potential predictors was analyzed by means of unconditional logistic regression models and stratified according to the duration of treatment. A stepwise regression analysis was performed to identify variables discriminated between subjects, using eradication status as the dependent variable. RESULTS The overall eradication rates for 1- and 2-wk treatments were 74.6% and 85.9% (intention-to-treat analysis) and 81.5% and 89.1% (per-protocol analysis), respectively (p = NS). Multivariate discriminant analysis selected as the variables independently related to eradication cigarette smoking (OR = 3.98), delta of 13C-UBT higher than 35 (OR = 9.21) and IgG anti-H. pylori titer > or = 93 (OR = 0.24) for the whole series of subjects. Stratified analysis according to the duration of therapy selected H. pylori density as the only predictor of eradication in the group treated for 1 wk (OR = 8.11). In contrast, no significant predictors were found in the group treated for 2 wk. CONCLUSIONS Patients with a high intragastric bacterial load, as detected by histology (grade 3) or 13C-UBT (delta > 35) may benefit from an extension to 2 wk of triple therapy with lansoprazole, amoxycillin, and clarithromycin.

Abstract
AIMS To compare the efficacy of one-week versus two-week treatment with lansoprazole, amoxycillin and clarithromycin in inducing healing of Helicobacter pylori-positive duodenal ulcers as well as to investigate the role of several factors, determinant in the ulcer healing process. PATIENTS AND METHODS Seventy-one active duodenal ulcer patients were randomised to receive one- or two-week treatment with lansoprazole (30 mg bid), clarithromycin (500 mg bid) and amoxycillin (1 g bid), not followed by any additional acid suppressive therapy. Ulcer healing and Helicobacter pylori infection were assessed by endoscopy and urea breath test 4 weeks after the end of treatment. Before entering the trial and four weeks after the end of treatment, dyspeptic symptoms were recorded and scored by a validated questionnaire. The potential effects of a number of clinical variables on the ulcer healing process were evaluated by means of univariate and multivariate analyses. RESULTS Duodenal ulcer was healed in 80.5% patients treated for one week and in 91.4% patients treated for 2 weeks according to intention-to-treat analysis (p=NS). Ulcer healing was more frequent in the Helicobacter pylori cured patients compared to those with persisting infection (90.9% vs 68.5%; p=0.04). Multivariate analysis did not reveal any significant predictor of duodenal ulcer healing. CONCLUSIONS Two-week treatment with lansoprazole, amoxycillin and clarithromycin, without continuation of antisecretive therapy, is better, although the difference is not statistically significant, than one-week treatment in healing Helicobacter pylori-positive duodenal ulcer disease. The eradication of Helicobacter pylori is the most important factor related to ulcer healing.

Abstract
AIM To evaluate the efficacy of pantoprazole in preventing gastrointestinal lesions in patients with rheumatic diseases receiving continuous, long-term treatment with non-steroidal anti-inflammatory drugs. MATERIAL This was a prospective, randomised, double-blind, unbalanced, placebo-controlled, parallel group study. Outpatients (n= 104, age range 22-80 years, mean age 59.5) with rheumatoid arthritis or osteoarthritis, requiring chronic intake of NSAIDs (at least 8 weeks prior to the start of the study), were randomised and enrolled to receive either 40 mg pantoprazole (n=70) or placebo (n=34) once daily, for 12 weeks. Patients had endoscopically confirmed gastric and duodenal lesions grade 0, 1 or 2 (Lanza classification grade 0: normal to hyperaemic mucosa; grade 1: 1 to 3 erosions, submucosal haemorrhage or petechiae, grade 2: 4 to 10 erosions, submucosal haemorrhages or petechiae). Clinical and endoscopic evaluations were performed at baseline, after 4, and 12 weeks. The primary end-point of the study was the incidence of gastric or duodenal ulcers after 4 and 12 weeks of treatment. RESULTS Patients (n=95) were evaluated: 65 in the pantoprazole group and 30 in the placebo group. When considering all patients (those with Lanza score grade 0, 1, 2 at baseline), the overall proportion of patients in remission was 82% and 77% after 4 weeks, and 72% and 59% after 12 weeks in pantoprazole and placebo groups, respectively (cumulative survival analysis according to Kaplan-Meier). The difference between the treatment groups was even more marked when only those patients with normal mucosa at baseline (grade 0) were considered. After 12 weeks, the proportion of patients in remission was 82% (95% confidence limits 70% - 94% in the pantoprazole and 55% (95% confidence limits 33% - 77%) in the placebo treatment group, p=O.036. Adverse events were reported in 4% and 6% of patients in pantoprazole and placebo treatment groups, respectively CONCLUSIONS Pantoprazole 40 mg once daily was well tolerated and is more effective than placebo in the prevention of peptic ulcers in patients with rheumatic diseases who require continuous, long-term, treatment with NSAIDs.

Abstract
OBJECTIVES To date, few studies have evaluated gastric histology in patients with inflammatory bowel disease (IBD). The aim of this prospective controlled study was to establish the frequency of focal gastritis in Crohn's disease (CD) and ulcerative colitis (UC) patients, as well as to evaluate its immunohistochemical characteristics and clinicoanatomical determinants. METHODS We evaluated 141 consecutive patients with known CD of the large and/or small bowel, 79 patients with UC, and 141 CD- and UC-free controls; all underwent upper gastrointestinal (GI) endoscopy and 13C urea-breath test. Biopsy specimens taken from the antrum, angulus, and gastric body were evaluated by histology and immunohistochemistry. A series of variables, including CD activity index, duration, extent and location of disease, intestinal resection, number of recurrences, and previous and current medical therapy, as well as the presence of dyspeptic symptoms and mucosal lesions at endoscopy, were determined in all CD patients and correlated with the presence or absence of focal gastritis. RESULTS Helicobacter pylori-associated gastritis was found in 47 patients with CD (33%), in 37 patients with UC (47%), and in 60% of CD-/UC-free controls (p < 0.01). In H. pylori-negative CD patients focal gastritis was found in 43% of cases (40/94), compared with 12% (5/42) of UC patients and 19% (11/57) of controls (p < 0.05). Specificity and positive predictive value of focal gastritis in CD were 84% and 71%, respectively. It was characterized by a focal perifoveolar or periglandular lymphomonocytic infiltrate, with CD8+/CD4+ cells predominant both in CD and UC patients. There were no significant correlations between the occurrence of focal gastritis and any clinicoanatomical CD features. CONCLUSIONS Focal gastritis is relatively common in CD patients although it is not exclusive to this condition. Its recognition could be useful in the diagnostic workup of any patient with suspected or indeterminate inflammatory bowel disease, as it makes a diagnosis of CD more likely.

Abstract
BACKGROUND H. pylori CagA seropositivity has been recently associated with ischaemic heart disease. OBJECTIVE To evaluate whether H. pylori virulence has any effect on certain circulating coagulation factors and on markers of systemic inflammation in healthy individuals. DESIGN Prospective cohort study. SETTING Haematology and gastroenterology unit at a university teaching hospital. SUBJECTS A total of 494 consecutive asymptomatic blood donors attending a blood bank. MEASUREMENTS Blood analysis for haemostatic factors, lipids concentrations, inflammatory parameters as well as determination of anti H. pylori IgG and CagA reactivity by ELISA assayes. RESULTS The overall prevalence of H. pylori infection was 53%; 56% of H. pylori positive sera expressed CagA reactivity. CagA seropositive subjects did not differ significantly from CagA negative or H. pylori negative subjects in values for lipids, haemostatic factors, or inflammatory parameters. CONCLUSIONS CagA seropositivity is not associated with increased systemic inflammation or with raised concentrations of haemostatic factors - predictors of ischaemic heart disease - in healthy individuals.

Abstract
AIM To compare the diagnostic accuracy of routine histology for Helicobacter pylori infection, with histology by an expert pathologist, and to compare histology with the rapid urease test (RUT), 13C-urea breath test, IgG serology and culture of antrum and corpus specimens, in a consecutive series of untreated patients presenting for upper oesophago-gastro-duodenoscopy. MATERIALS AND METHODS One-hundred and fifteen consecutive patients underwent multiple tests for H. pylori infection: rapid urease test, 13C-urea breath test, IgG serology and histology and culture on antrum and corpus biopsy specimens. Histology was first evaluated by the pathologists in a routine examination, and then blindly reviewed by an expert pathologist with a special interest in gastrointestinal pathology. The patients were considered to be H. pylori-positive if two or more tests were positive. RESULTS Eighty-one patients (70.4%) were found to be H. pylori positive. 13C-urea breath test and IgG serology showed the best sensitivity and specificity (100%). Both the antral and body cultures, and the rapid urease test had the highest specificity (100%). Histological diagnosis after re-evaluation by an expert pathologist showed a high sensitivity (98. 8%) and specificity (100%), and was better than routine histology (sensitivity 92.6%; specificity 90.3%). The accuracy of the rapid urease test was greater than that of routine histology, and the combination of these two tests improved the sensitivity of H. pylori detection to up to 100%. CONCLUSION All diagnostic tests usually utilised in clinical practice have a sensitivity higher than 90%. In patients who were not pre-treated with antisecretory agents or antibiotics, the sensitivity of histological diagnosis, however, seems to be influenced by the accuracy of the histological examination. The sensitivity of routine histology, but not of revised histological diagnosis, is improved by an additional rapid urease test.

Abstract
BACKGROUND The efficacy of sulphasalazine and mesalazine in preventing relapse in patients with ulcerative colitis is well known. It is less clear how long such maintenance should be continued, and if the duration of disease remission is a factor that affects the risk of recurrence. AIM To determine whether the duration of disease remission affects the relapse rate, by comparing the efficacy of a delayed-release mesalazine (Asacol, Bracco S.p.A., Milan, Italy) against placebo in patients with ulcerative colitis with short- and long-duration of disease remission. METHODS 112 patients (66 male, 46 female, mean age 35 years), with intermittent chronic ulcerative colitis in clinical, endoscopic and histological remission with sulphasalazine or mesalazine for at least 1 year, were included in the study. Assuming that a lower duration of remission might be associated with a higher relapse rate, the patients were stratified according to the length of their disease remission, prior to randomization into Group A (Asacol 26, placebo 35) in remission from 1 to 2 years, or Group B (Asacol 28, placebo 23) in remission for over 2 years, median 4 years. Patients were treated daily with oral Asacol 1.2 g vs. placebo, for a follow-up period of 1 year. RESULTS We employed an intention-to-treat analysis. In Group A, whilst no difference was found between the two treatments after 6 months, mesalazine was significantly more effective than placebo in preventing relapse at 12 months [Asacol 6/26 (23%), placebo 17/35 (49%), P = 0.035, 95% Cl: 48-2.3%]. In contrast, in Group B no statistically significant difference was observed between the two treatments, either at 6 or 12 months [Asacol 5/28 (18%), placebo 6/23 (26%), P = 0.35, 95% Cl: 31-14%] of follow-up. Patients in group B were older, and had the disease and remission duration for longer, than those in Group A. CONCLUSIONS Mesalazine prophylaxis is necessary for the prevention of relapse by patients with ulcerative colitis in remission for less than 2 years, but this study casts doubt over whether continuous maintenance treatment is necessary in patients with prolonged clinical, endoscopic and histological remission, who are at very low risk of relapse.

Abstract
BACKGROUND Current knowledge on splanchnic haemodynamics in Crohn's disease is limited. AIMS To investigate which features of Crohn's disease affect splanchnic haemodynamics, and to establish whether portal vein (PV) and superior mesenteric artery (SMA) blood supply reflects clinical or biochemical activity of Crohn's disease. METHODS Seventy nine patients with Crohn's disease and 40 controls were evaluated by Doppler ultrasound (US). The mean velocity of PV and SMA flow, the volume of blood flow of the PV and SMA, and the resistance index of SMA were studied. A series of clinical, biochemical, and US variables including Crohn's disease activity index, serum C reactive protein concentrations, disease duration and its anatomical location, smoking habits, abdominal complications, and current medical therapy, as well as the maximum bowel wall thickness as measured by US, were determined. The relation between PV and SMA blood flow and these variables was assessed by univariate and multivariate analysis. RESULTS Patients with Crohn's disease had significantly higher PV and SMA flow and a lower SMA resistance index than controls. Stepwise multiple regression analysis identified bowel wall thickness and location of the disease as the main predictive variables of both PV and SMA blood flow variation, accounting for 36% and 45% of their variability, respectively. No relation was found between splanchnic haemodynamics and disease activity. CONCLUSION A hyperdynamic mesenteric circulation does exist in Crohn's disease; however splanchnic blood flow does not reflect the clinical or biochemical activity of the disease, but seems to be linked more to other Crohn's disease characteristics, such as maximum bowel thickness and anatomical location.

Abstract
OBJECTIVE To date, little is known about a possible relationship between H. pylori-related disturbances of gastric function and the bacterial virulence. The aim of this study was to assess whether certain gastric function indices as well as the pattern of symptoms in nonulcer dyspepsia (NUD) are related to CagA status. METHODS A total of 56 consecutive patients with NUD (38 H. pylori-positive and 18 H. pylori-negative) were studied. Dyspeptic symptoms were categorized according to the predominant complaints and scored for severity and frequency. In all subjects, basal and pentagastrin-stimulated acid secretion, fasting and meal-induced gastrin release, fasting serum pepsinogen I (PG I) levels, and gastric emptying of solids were determined. CagA status was determined by assaying serum CagA IgG antibodies by western blotting. RESULTS Eighteen of 38 (47%) H. pylori-positive dyspeptics were CagA seropositive. Type and severity of dyspeptic symptoms did not significantly differ between CagA-positive and CagA-negative dyspeptics nor between H. pylori-positive and negative patients. Among the gastric function indices studied, only meal-stimulated gastrin was significantly influenced by CagA status (peak gastrin 129.9 [44.1] vs 99.1 [48.6] pg/ml in CagA-positive and negative NUD, respectively), but this was not accompanied by any significant modification of basal or stimulated acid secretion or gastric emptying of solids. The activities of both antral and corpus gastritis in NUD harboring CagA-positive strains were significantly higher than those of CagA-negative NUD. Accordingly, serum PG I levels were significantly higher in CagA-positive than CagA-negative or H. pylori-negative dyspeptics. CONCLUSIONS These findings support a role for CagA status in influencing the activity and perhaps the distribution of gastritis in NUD, as well as the degree of gastrin response to a meal; however, this is not accompanied by disturbances of acid secretion or gastric emptying or by differences in the type and severity of symptoms.

Abstract
BACKGROUND To date, it is unclear whether Helicobacter pylori infection is associated with disturbances of gastric emptying or acid secretion in patients with functional dyspepsia (FD). Our aim was to investigate whether, in the long run, cure of H. pylori infection significantly influences gastric emptying of solids, acid secretion, and gastrin and pepsinogen I (PGI) release in patients with FD. METHODS Thirty-eight consecutive H. pylori-positive patients with FD, whose complaints were scored for severity and frequency on the basis of a validated symptom questionnaire, were initially enrolled in the study. They were randomized to receive an eradicating regimen consisting of omeprazole plus clarithromycin and tinidazole for 1 week or full-dose ranitidine for 3 weeks. In 33 patients (18 H. pylori-cured and 15 with persistent infection) basal and pentagastrin-stimulated acid secretion, fasting and meal-induced gastrin concentrations, fasting serum PGI levels, and gastric emptying of solids were determined before and 6 months after therapy. RESULTS In the 18 H. pylori-cured patients meal-induced gastrin and fasting PGI levels were significantly reduced after 6 months as compared with pretreatment values (peak serum gastrin, 76.0 +/- 23.4 versus 111.9+/-37.4 pg/ml; PGI, 57.1+/-23.4 versus 72.9+/-29.1 ng/ml), whereas they remained virtually unchanged in the 15 patients with persistent infection. In contrast, both basal and stimulated acid secretion and gastric emptying time of solids remained unmodified over time in both groups of patients. CONCLUSIONS We confirm that also in patients with functional dyspepsia H. pylori eradication in the long run significantly reduces gastrin and PGI release as a result of improvement in the underlying antral gastritis, but this is not accompanied by modifications of gastric emptying of solids or acid secretion.

Abstract
We evaluated, retrospectively, the outcome of 56 patients (39 male, 17 female; mean age, 34 years; age range, 14-65 years) who received azathioprine for either steroid-resistant (group A, n = 10) or steroid-dependent (group B, n = 46) ulcerative colitis. The patients were followed for a mean of 29 +/- 17 months (median, 27 months). Twenty-four had left-sided colitis, 5 had subtotal colitis, and 27 had total colitis. The mean duration of the disease was 51 months (range, 2-192 months). At the beginning of azathioprine treatment (time 0), all patients had clinically severe disease and were taking 40 mg prednisolone per day. Azathioprine was used in addition to steroid therapy at a dosage of 2 mg/kg. The need for steroids, expressed as the median cumulative steroid dose (mg/year), and the number of clinical relapses (requiring steroid therapy) in the 2 years before azathioprine treatment, were compared with those of the 3-year follow-up with azathioprine treatment. A positive response to azathioprine was defined as (a) avoidance of colectomy, (b) a significant decrease in the median cumulative steroid dose, and (c) a significant decrease in the number of clinical relapses (expressed as number/patient/year). One patient in group A withdrew due to painful dyspepsia, and two patients in group B were lost to follow-up. Remission with complete elimination of steroids was achieved in 36 of 53 (64%), 23 of 35 (66%), and 18 of 26 (69%) patients in the first, second, and third years, respectively, of azathioprine treatment. Compared with the 2 years before azathioprine treatment, a significant decrease was observed of about 75% both in steroid consumption and in the number of clinical relapses during the 3 years of azathioprine therapy. Two of nine patients in group A and 2 of 44 patients in group B had colectomy after mean periods of 15 months and 24 months, respectively. Azathioprine is effective and safe in avoiding colectomy in patients with steroid-resistant and steroid-dependent ulcerative colitis; its use decreases both steroid requirements and clinical relapses.

Abstract
BACKGROUND The relation between Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID)-associated peptic ulcers remains unclear; in particular, it is not known whether H pylori plays a part in the healing and recurrence of these ulcers. AIMS To evaluate prospectively in a consecutive series of arthritis patients receiving longterm NSAID treatment the prevalence of peptic ulcer as well as the effect of H pylori eradication on the healing and recurrence of gastric and duodenal ulcer found. PATIENTS Some 278 consecutive patients underwent gastroscopy with multiple biopsies of the gastric antrum and corpus for histological examination and rapid urease test. One hundred peptic ulcers (59 gastric ulcers, 39 duodenal ulcers, and two gastric ulcers concomitant with a duodenal ulcer) were found. Seventy per cent of these ulcers were H pylori positive. METHODS According to their H pylori status, ulcer patients were randomised to one of the following treatments: H pylori negative ulcers received omeprazole 20 mg twice daily for four to eight weeks, whereas H pylori positive lesions were treated with omeprazole 20 mg twice daily plus amoxycillin 1 g twice daily (the second of these for the first two weeks) or omeprazole alone for four to eight weeks while continuing NSAID therapy. Patients with healed ulcers were endoscopically followed up for six months after stopping antiulcer therapy while continuing NSAIDs. RESULTS Endoscopic healing rates for gastric and duodenal ulcers in the three different groups were similar both at four and eight weeks. H pylori eradication did not influence healing, which occurred in 14 of 20 (70%) of patients in whom H pylori was eradicated, compared with 14 of 17 (82%) of patients with persistent infection. Cumulative recurrence rates at six months did not statistically differ among the three different groups (27% in H pylori negative, 46% in H pylori positive, and 31% in those where H pylori was eradicated during the healing phase), although a numerical trend in favour of a higher recurrence rate in infected patients was evident. CONCLUSIONS H pylori eradication does not confer any significant advantage on the healing of gastric and duodenal ulcers associated with longterm NSAID use. It remains to be established with certainty whether eradication may be helpful in the reduction of recurrence in a specific subset of NSAID associated ulcer.

Abstract
BACKGROUND Our aim was to assess the role of Doppler ultrasound (US) in detecting changes in the splanchnic hemodynamic variables measured in patients with active or quiescent inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS) and healthy subjects. METHODS Sixty-five patients, 31 with Crohn's disease (CD), 24 with ulcerative colitis (UC), 10 with IBS, and 10 matched normal subjects were evaluated by means of Doppler US. The mean velocity of portal and mesenteric venous flow, the blood flow volume of portal and mesenteric veins, and the resistance index (RI) of the superior mesenteric artery (SMA) were studied in all patients. RESULTS Patients with active IBD had a splanchnic venous flow that was significantly higher, and an RI of the SMA significantly lower, than the IBS patients and healthy controls; however, a higher portal and mesenteric blood flow and lower RI of the SMA was documented in patients with active UC but not in those in whom the disease was quiescent. Patients with quiescent CD had significantly higher portal and mesenteric blood flow and lower RI of the SMA than IBS and healthy controls. No significant differences were found between IBS patients, quiescent UC patients, and healthy controls. CONCLUSION This study shows that Doppler US can demonstrate splanchnic hemodynamic changes in active IBD patients and, in particular, can be used to differentiate between active and quiescent UC. However, the assessment of CD activity by means of Doppler US requires further investigation.

Abstract
OBJECTIVE The objective of this endoscopic, double-blind study was to evaluate the gastric tolerability of nabumetone, a novel nonsteroidal anti-inflammatory drug, compared with naproxen in patients with rheumatoid arthritis. METHODS Patients with definite or classic rheumatoid arthritis as defined by ACR criteria were eligible for entry into the study if an initial endoscopy was normal or showed the presence of only one erosion or one or two submucosal hemorrhages. After a 7-day washout period, the patients were randomized to receive either nabumetone, 1 g, or naproxen, 500 mg, b.i.d. Blinding was achieved by the use of double dummies. Endoscopy was repeated after 4 wk of treatment. The primary efficacy parameters were Ritchie articular index, duration of morning stiffness, and global assessments. RESULTS Gastric mucosal lesions of different degrees were observed in 9% (2/22) of nabumetone-treated patients and in 40% (12/30) of those who received naproxen (p = 0.01). One duodenal ulcer was found in a patient treated with nabumetone, and this patient had a history of duodenal ulcer. In the naproxen group, six patients were found to have an ulcer. Clinical evaluation of rheumatological symptomatology showed no statistical difference in relieving symptoms between the two drugs in the primary efficacy assessments. However, six nabumetone-treated patients dropped out because of lack of efficacy, compared with one in the naproxen group. Side effects were noted in three patients treated with nabumetone and in 14 treated with naproxen (p = 0.004). CONCLUSION This study showed that nabumetone, 1 g daily, results in significantly less deterioration of gastric mucosa than naproxen, 500 mg daily, but the efficacy of naproxen, 1 g, appears to be more than that achieved with nabumetone, 1 g.

Abstract
OBJECTIVES To compare a low dosage (1 g/day) rectal preparation of 5-aminosalicylic acid in slightly acidic, buffered suspension (Pentasa) with a hydrocortisone 100 mg/day enema (Cortenema). METHODS Fifty-two patients with mild to moderate distal ulcerative colitis were randomized under double-blind conditions to receive a rectal preparation of either Pentasa (1 g/day) or Cortenema (100 mg/day) for 3 wk. RESULTS After 3 wk, both types of treatment resulted in statistically significant improvements in clinical and endoscopic activity. No significant difference was observed between the two drugs in any of the parameters considered, although a statistical trend in favor of Pentasa was evident when analysis was limited to clinical activity (p = 0.07). No side effects were reported in either group. CONCLUSIONS Our experience confirms that short term topical treatment with a low dosage 5-aminosalicylic acid is at least as effective as 100-mg hydrocortisone enemas in treating mild to moderate distal ulcerative colitis and is generally well tolerated.
