Abstract
BACKGROUND Invasive Meningococcal Disease is a severe disease mainly affecting infants and young children. Most infections are caused by serogroups A, B, C, W, X, and Y. In the last 10 years, serogroup B has been the main cause of Invasive Meningococcal Disease in Europe. Recent data resulting from an observational study conducted in Italy show a significant reduction in the number of Invasive Meningococcal Disease cases due to Neisseria meningitidis B after the introduction of vaccine 4CMenB. Thus, the Naples Team of Federation of Italian Primary Care Pediatricians and the Public Health Department started an active collaboration focused on vaccination process management (named "Progetto Via") with the aim of increasing Meningococcal B vaccination coverage. STUDY DESIGN Source of data is the regional platform "GE.VA.". Every Primary care Pediatrician uses daily to record vaccination activity. This platform is integrated with data entered by operators of the District/Vaccination Center. METHODS Time: January 2019 - December 2019. The Federation of Italian Primary Care Pediatricians/Naples organized a meeting to identify six coordinators. The pediatricians could choose to counsel in their own offices and send children to the vaccination center or to counsel and vaccinate directly in their own clinics. RESULTS A total of 78 pediatricians took part in the project: 46 did only counseling and 32 did both counseling and vaccination in their medical clinic. Data obtained show an overall average vaccination coverage growth of about 13% in the first 4 months of the survey, and a further growth of about 11% in the following seven months, with a total growth in the entire period of 24%. The pediatricians' counseling is essential to recover non-compliant subjects, considering both the relationship of trust with the families and the visits already scheduled as an ideal moment for vaccinations' status check. CONCLUSIONS The project highlights how an effective collaboration between family pediatricians and the Local Health Authority becomes valuable in getting closer to reach the Ministerial goal of 95%. Vaccination coverage increased significantly when family pediatricians supported the activity of vaccine centers in distress in many regional situations. The trust relationship, the hourly availability and the capillary network of family pediatricians' clinics were key elements for the success of this project and were also recognized by parents.

Abstract
PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings have not yet been standardized. The aim of this evidence-based and consensus-based guideline, commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to furnish healthcare providers with a comprehensive framework for potential implementation of this technique in a clinical setting.

Abstract
These recommendations on video capsule endoscopy, an emerging technology with an impact on the practice of endoscopy, were developed by the European Society of Gastrointestinal Endoscopy (ESGE) Guidelines Committee. The first draft of each section was prepared by one or two members of the writing team, who were selected as experts on the content of that section on the basis of their published work. They used evidence-based methodology, performing MEDLINE and PubMed literature searches to identify relevant clinical studies. Abstracts from scientific meetings were included only if there was no published full paper on a particular topic. If there was disagreement, the first author of the Guideline made the final decision. Recommendations were graded according to the strength of the supporting evidence. The draft guideline was critically reviewed by all authors and submitted to the ESGE councillors for their critical review before approval of the final document. The ESGE Guidelines Committee acknowledges that this document is based on a critical review of the data available at the time of preparation and that further studies may be needed to clarify some aspects. Moreover, this Guideline may be revised as necessary to account for changes in technology, new data, or other aspects of clinical practice. This document should be regarded as supplying recommendations only to gastroenterologists in providing care to their patients. It is not a set of rules and should not be construed as establishing a legal standard of care, or as encouraging, advocating, requiring, or discouraging any particular treatment. These recommendations must be interpreted according to the clinician's knowledge, expertise, and clinical judgment in the management of individual patients and, if necessary, a course of action that varies from recommendations must be undertaken.

Abstract
BACKGROUND AND AIM Variceal bleeding carries a high-mortality rate in patients with liver cirrhosis. Since coagulation and fibrinolysis are abnormal in these patients we evaluated whether or not abnormalities of these haemostasis systems were independently related to mortality. METHODS Global coagulation, coagulation activation and fibrinolysis measurements were performed in 43 cirrhotics bleeding from esophageal varices at baseline and during follow-up and in 43 non-bleeding cirrhotic patients at baseline only. RESULTS Baseline measurements of coagulation activation and fibrinolysis were more impaired in bleeders. In bleeders, prothrombin time, tissue type plasminogen activator antigen and D-dimer plasma levels were persistently more abnormal in patients who died. High-D-dimer, infection, Child-Pugh C class and MELD score >or=17 were the significant predictors of death at univariate analysis. Two different multivariate analyses to assess the independent prognostic value of these variables, one including the Child-Pugh class, the other including MELD, were performed. Independent predictors of death were high-D-dimer and infection, but not Child-Pugh class, in the former; MELD and infection, but not D-dimer, in the latter. CONCLUSIONS Beside infection, high-D-dimer is a stronger predictor of death as compared to Child-Pugh C class, but not to a MELD score >or=17.

Abstract
BACKGROUND Thiopurines are the most commonly used immunomodulatory drugs in inflammatory bowel diseases. AIM To evaluate the use, the therapeutic and safety profiles of thiopurines in a large sample of IBD patients. METHODS We reviewed 3641 case histories of IBD patients. Thiopurines were prescribed in 582 patients (16.0%); the analysis was performed on the 553 (267 ulcerative colitis, 286 Crohn's disease) with exhaustive clinical data. RESULTS The main indications for treatment were steroid-dependence (328/553, 59.3%) and steroid-resistance (113/553, 20.7%). Thiopurines were started when CD were younger than UC patients (p<0.001) but earlier from diagnosis in UC than in CD patients (p=0.003). Efficacy was defined as optimal (258/553, 46.6%), partial (108/553, 19.5%), absent (85/553, 15.4%) and not assessable (102/553, 18.4%). Efficacy was independent of disease type, location/extension or duration and age at starting. Side effects were observed in 151/553 (27.3%) patients, leading to drug discontinuation in 101 (18.3%). 15 out of the 130 (11.5%) patients who took thiopurines for more than 4 years relapsed, more frequently in CD than in UC (OR=3.67 95% C.I. 0.98-13.69; p=0.053). CONCLUSIONS Thiopurines confirm their clinical usefulness and acceptable safety profile in managing complicated IBD patients. The majority of patients treated for longer than 4 years maintain response. No clinical and demographic predictive factors for efficacy and side effects were identified.

Abstract
BACKGROUND Efficacy of heparin and low-molecular-weight heparins (LMWHs) in inflammatory bowel disease (IBD) treatment has been suggested. The multimatrix oral formulation MMX releases active drugs in the colon, avoiding systemic absorption. Parnaparin sodium is the LMWH chosen to be carried in the MMX formulation. AIM To assess the safety of three different oral dosages (70, 140 and 210 mg once daily) of Parnaparin-MMX (CB-01-05) in left-sided ulcerative colitis (UC). METHODS Left-sided UC patients, with a mild-to-moderate relapse were enrolled. All patients received Parnaparin-MMX for 8 weeks. Clinical Activity Index (CAI), Disease Activity Index (DAI), Endoscopic Activity Index and IBD-QoL were assessed throughout the study. A strict clinical and laboratory follow-up, including assessment of anti-factor Xa activity, was performed. Clinical remission was defined as CAI <4. RESULTS Ten UC patients were enrolled. One patient retired for clinical deterioration. No relevant side effects, including either interference with haemostasis parameters or increased bleeding, were observed. At the end of the treatment, seven patients (70%) were in clinical remission, only one achieving endoscopic healing. Mean final CAI, DAI and IBD-QoL scores were significantly improved from baseline. CONCLUSIONS Parnaparin-MMX appears to be a safe treatment option in mild-to-moderate UC. Controlled studies are warranted.

Abstract
BACKGROUND AND STUDY AIM Small-bowel tumors account for 1% - 3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tumors in a large population of patients undergoing VCE. PATIENTS AND METHODS Identification by a questionnaire of patients with VCE findings suggesting small-bowel tumors and histological confirmation of the neoplasm seen in 29 centers of 10 European Countries. RESULTS Of 5129 patients undergoing VCE, 124 (2.4%) had small-bowel tumors (112 primary, 12 metastatic). Among these patients, indications for VCE were: obscure gastrointestinal bleeding (108 patients), abdominal pain (9), search for primary neoplasm (6), diarrhea with malabsorption (1). The main primary small-bowel tumor type was gastrointestinal stromal tumor (GIST) (32%) followed by adenocarcinoma (20%) and carcinoid (15%); 66% of secondary small-bowel tumors were melanomas. Of the tumors, 80.6% were identified solely on the basis of VCE findings. 55 patients underwent VCE as the third procedure after negative bidirectional endoscopy. The lesions were single in 89.5% of cases, and multiple in 10.5%. Retention of the capsule occurred in 9.8% of patients with small-bowel tumors. After VCE, 54/124 patients underwent 57 other examinations before treatment; in these patients enteroscopy, when performed, showed a high diagnostic yield. Treatment was surgery in 95% of cases. CONCLUSIONS Our data suggest that VCE detects small-bowel tumors in a small proportion of patients undergoing this examination, but the early use of this tool can shorten the diagnostic work-up and influence the subsequent management of these patients.

Abstract
Currently, oesophago-gastroduodenoscopy is the standard method to diagnose the presence of oesophago-gastric varices and to estimate the risk of bleeding. It is recommended that all patients undergo endoscopic screening for varices at the time when cirrhosis is diagnosed. After screening endoscopy, patients with medium or large varices should be treated to prevent bleeding, while all other patients should undergo periodic surveillance endoscopy. However, at a given point in time a variable proportion of patients will not have varices, since the prevalence of varices is variable. Thus, screening all cirrhotic patients with endoscopy to detect the presence of varices implies a number of unnecessary endoscopies. In recent years a wealth of new methods have been proposed as alternatives to conventional oesophago-gastroduodenoscopy for the non-invasive or minimally invasive diagnosis of oesophageal varices. Three of these methods (the platelet count/spleen diameter ratio, Fibrotest and Fibroscan) are truly non-invasive. Of these, the former is promising and needs a proper validation, Fibrotest appears to be insufficiently precise, while Fibroscan needs further evaluation. Multidetector CT oesophagography and capsule endoscopy are not entirely "non-invasive", since the first requires air insufflation into the oesophagus via an orally passed tube, and the latter requires swallowing the capsule. Multidetector CT oesophagography is promising, but needs further evaluation; capsule endoscopy is safe and reliable and might be proposed as an alternative to oesophago-gastroduodenoscopy in patients unable or unwilling to undergo oesophago-gastroduodenoscopy.

Abstract
Variceal bleeding is one of the most severe complications of portal hypertension related to liver cirrhosis. Primary prophylaxis is considered mandatory in patients with cirrhosis and high-risk oesophageal varices, and once varices have bled, every effort should be made to arrest the haemorrhage and prevent further bleeding episodes. In acute variceal bleeding, vasoactive drugs that lower portal pressure should be started even before endoscopy, and should be maintained for up to 5 days. The choice of vasoactive drug should be made according to local resources. Terlipressin, somatostatin and octreotide can be used; vasopressin plus transdermal nitroglycerin may be used if no other drug is available. In variceal bleeding, antibiotic therapy is also mandatory. In primary and secondary prophylaxis, beta-blockers are the mainstay of therapy.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) have an increased prevalence of thromboembolic events. The pathogenetic mechanisms of these events include reduced fibrinolysis, which may be caused by antibodies to tissue-type plasminogen activator (t-PA). OBJECTIVES To evaluate anti-t-PA antibodies in patients with IBD, considering clinical, biochemical and functional characteristics. PATIENTS AND METHODS We immunoenzymatically measured anti-t-PA antibodies in plasma from 97 consecutive IBD patients and 97 age- and sex-matched healthy controls. We also assessed the antibody interactions with different epitopes of t-PA, the antibody inhibition on t-PA activity and the correlations with clinical features and other serum antibodies. RESULTS IBD patients had higher median anti-t-PA antibody levels (5.4 U mL(-1) vs. 4.0 U mL(-1); P < 0.0001): 18 patients were above the 95th percentile of the controls (OR 5.3; 95% CI 1.7-16.3; P < 0.003), and the six with a history of thrombosis tended to have high levels (6.9 U mL(-1)). Anti-t-PA antibody levels did not correlate with IBD type, activity, location or treatment, or with age, sex, acute-phase reactants or other antibodies. The anti-t-PA antibodies were frequently IgG1 and bound t-PA in fluid phase; they recognized the catalytic domain in 10 patients and the kringle-2 domain in six. The IgG fraction from the three patients with the highest anti-t-PA levels slightly reduced t-PA activity in vitro. CONCLUSIONS The prevalence of anti-t-PA antibodies is high in IBD patients. By binding the catalytic or kringle-2 domains of t-PA, these antibodies could lead to hypofibrinolysis and contribute to the prothrombotic state of IBD.

Abstract
BACKGROUND Capsule enteroscopy is a non-invasive diagnostic tool for the study of the small bowel. Due to the risk of capsule retention, capsule enteroscopy is contraindicated in patients with suspected small bowel strictures. The Given Patency Capsule is a disintegration time-controlled capsule developed to identify patients with strictures that may cause capsule enteroscopy retention. The presence of the patency capsule within the patient's body can be detected by a radio-frequency scanner. AIM OF THE STUDY To evaluate safety and usefulness of the patency capsule in preventing capsule retention in patients at high risk. PATIENTS AND METHODS Thirty-two patients were studied. Indications for patency capsule were: (A) Crohn's disease (18), (B) previous intestinal surgery (7), (C) previous obstruction (1), A+B (3), A+C (1), B+C (2). Patients were evaluated with the scanner at 72 h from ingestion. RESULTS At 72 h, 24 patients had already excreted the intact capsule in the stool. Of these, two experienced abdominal pain during capsule passage. In the other eight patients, the scanner detected the presence of the patency capsule. Four of them excreted the capsule intact in the stool after 72-96 h, the remaining four never found the capsule in the stool. The 26 patients who excreted the patency capsule intact without experiencing abdominal pain were deemed eligible for the capsule enteroscopy procedure, which was performed uneventfully in the 25 who agreed to undergo the examination. CONCLUSIONS The patency capsule is useful to identify, among patients at high risk, those who can be submitted to capsule enteroscopy without risks of capsule retention.

Abstract
BACKGROUND AND STUDY AIMS Capsule enteroscopy has become a standard tool for the evaluation of obscure gastrointestinal bleeding. Reviewing the video recordings of capsule examinations is time-consuming and requires prolonged attention. Recently, software that can recognize the frames containing "red spots", the Suspected Blood Identification system (SBIS), has been developed with the aim of assisting in the analysis of video recordings. We assessed the sensitivity and specificity of the SBIS in patients undergoing capsule enteroscopy. PATIENTS AND METHODS 100 consecutive patients underwent capsule enteroscopy at our tertiary referral center, for the following indications: obscure gastrointestinal bleeding (75 patients), metastatic carcinoid (7 patients) known or suspected Crohn's disease (5 patients), miscellaneous (13 patients). Capsule endoscopy was carried out by the standard method. Four gastroenterologists, experienced in capsule endoscopy, reviewed the recordings. RESULTS Small-bowel visualization was obtained in 95 cases. The physicians identified 209 "red spots", 54 of which (25.8%) were also identified by the SBIS. The overall sensitivity, specificity, and positive and negative predictive values of the SBIS, calculated on the number of true-positive, true-negative, false-positive and false-negative results, were 40.9%, 70.7%, 69.2% and 42.6%, respectively. Sensitivity was higher for the identification of red blood (60.9%) than for nonbleeding "red" lesions such as arteriovenous malformations (25.8%). CONCLUSIONS The SBIS has low sensitivity and specificity. It can be used as a complementary and rapid screening tool, but complete review of the recordings is still necessary.

Abstract
BACKGROUND AND STUDY AIMS Capsule endoscopy (CE) is an effective means of investigating the small bowel in patients with gastrointestinal diseases. Computerized reports are frequently used in endoscopy, and the Minimal Standard Terminology (MST) has been promoted by endoscopy societies as the official vocabulary for endoscopy. The aims of this study were to design a lexicon for CE reports based on the principles of the MST and to validate lists of terms for describing findings and reasons for performing a CE by cross-matching them with the results of CE procedures collected during ongoing clinical studies. MATERIALS AND METHODS A consensus-based Capsule Endoscopy Structured Terminology (CEST) was developed by experts involved in CE studies. Lists of terms suitable for CE were designed for the various sections of an endoscopic report. They were then correlated with the corresponding MST lists for duodenal and intestinal endoscopy. The results of 766 CE procedures, collected in an electronic case record form (eCRF), were analyzed to provide lists of reasons for performing the procedures and of the findings. The eCRF provided only a limited number of items for each data field, along with free-text facilities. Only descriptions pertaining to the small bowel were analyzed. Lists of terms were then reviewed by two experts to group obvious synonyms. The accuracy of the CEST was defined beforehand as the capability to describe 90 % of entries. RESULTS A total of 766 CE procedures were analyzed. The eCRF included 824 entries as reasons for the examination in 655 CEs (1.3 per procedure). These represented 122 different expressions. After grouping of synonyms, 28 expressions remained. Among them, 10 were matched with terms from the list of reasons for performing CE offered in the CEST. These were the most frequently used, accounting for 768 entries in this field (93.2 %). All eCRFs contained at least one description of findings. A total of 109 CE procedures were classified as normal (14.3 %). A total of 2624 entries for abnormal findings were recorded for 657 procedures (4.0 per procedure). In all, 213 different expressions were used to describe abnormal findings. After grouping of synonyms, 52 expressions remained. Among these, 27 were matched with terms from the list of findings in the CEST, covering 2403 entries (91.6 %). CONCLUSIONS In this study, CEST terms were capable of describing more than 90 % of the reasons for performance and of the findings in an unselected set of CE procedures. CEST is therefore suitable for use as the standard lexicon for CE reports. Adopted as a standard, it could significantly improve the quality of the data collected and reported in CE studies.

Abstract
Prevention of the first variceal haemorrhage should start when the patients have developed medium-sized to large varices. Non-selective beta-blockers and band ligation are equally effective in preventing the first bleeding episode. Rubber band ligation is the first choice for patients with contraindications or intolerance to beta-blockers. Treatment of acute bleeding should aim at controlling bleeding and preventing early rebleeding and complications, especially infections. Combined endoscopic (band ligation or sclerotherapy) and pharmacological treatment with vasoactive drugs can control bleeding in up to 90% of patients. Antibiotic prophylaxis is an integral part of the treatment of acute variceal haemorrhage, and must be started as soon as possible. Emergency transjugular intrahepatic portosystemic stent shunt (TIPS) is the standard rescue therapy for patients failing combined endoscopic and pharmacological treatment. All patients who survive a variceal bleed should be treated with beta-blockers or band ligation to prevent rebleeding. All patients in whom bleeding cannot be controlled or who continue to rebleed can be treated with salvage TIPS or, in selected cases, with surgical shunts. Liver transplantation should be considered for patients with severe liver insufficiency in which first-line treatments fail.

Abstract
OBJECTIVES Hypofibrinolysis has been proposed as a possible mechanism underlying the known risk of thrombosis observed in patients with inflammatory bowel diseases (IBD). Thrombin-activatable fibrinolysis inhibitor (TAFI) is a recently described inhibitor of fibrinolysis. Increased TAFI plasma levels are associated with a risk for venous thrombosis. The objective was to evaluate TAFI plasma levels and their possible correlations with clinical features and acute-phase reactants in IBD patients. METHODS Eighty-one IBD patients (47 Crohn's disease and 34 ulcerative colitis) and 81 sex- and age-matched healthy controls were enrolled in the study; moreover, we studied 30 inflammatory controls (13 Reiter's syndrome, 4 Behçet's syndrome, and 13 patients with newly diagnosed celiac disease). TAFI plasma levels were assessed by means of a commercially available ELISA kit. Erythrocytes sedimentation rate, C-reactive protein, and alpha1-acid glycoprotein were measured as acute-phase reactants. Statistical analysis was performed by means of nonparametric tests and Fisher's exact test and chi(2) test for independence. RESULTS Median TAFI plasma levels were significantly higher in IBD patients (116.0%, range: 39.0-232.0%) and in inflammatory controls (176.0%, 50.0-435.0%) than in healthy controls (99.0%, 40.0-170.0%) (p< or = 0.05 and p< or = 0.001, respectively). TAFI plasma levels higher than the 95th percentile of control values were significantly more frequent in IBD patients (19.7%) and in inflammatory controls (53.3%) than in healthy controls (4.9%) (p< or = 0.008 and p< or = 0.0001, respectively) and more frequent in clinically active IBD than in clinically quiescent IBD (31.4%vs 10.9%, p< or = 0.03). Finally, in IBD, significant correlations were observed between TAFI plasma levels and erythrocytes sedimentation rate (p< or = 0.02), C-reactive protein (p< or = 0.001), and alpha1-acid glycoprotein (p< or = 0.05). CONCLUSIONS TAFI plasma levels are increased in IBD patients and correlate with acute-phase reactants. Increased TAFI plasma levels might contribute to the prothrombotic state observed in IBD through the induction of hypofibrinolysis.

Abstract
The goals of the Baveno workshops were to develop consensus definitions of key events related to portal hypertension and variceal bleeding, and to produce guidelines to facilitate the conduct and reporting of clinical trials. The consensus definitions concern the diagnosis of active bleeding, failure to control bleeding, the criteria to distinguish continuing bleeding from rebleeding, and the means of assessing failure to prevent rebleeding. The guidelines concern the timing of diagnostic endoscopy, the policy for blood volume restitution, the measures to prevent infection and encephalopathy, and the treatment options for acute bleeding, as well as primary and secondary prophylaxis. The intention of the experts who developed the guidelines was that, as feedback from their practical application develops, they should be adapted to better fit the practical needs. The applicability of the Baveno definitions has been evaluated in a study where the definitions of clinically significant bleeding, failure to control bleeding, the time frame for the acute bleeding episode and the definition of rebleeding were tested. The main criticism raised in this study was that tachycardia, one of the criteria that define failure to control bleeding, was misleading in 15% of patients who had the symptom but were not bleeding.

Abstract
Somatostatin and its analogues have been compared with a variety of other treatments for the treatment of variceal bleeding in cirrhotic patients. Meta-analyses of studies comparing somatostatin or octreotide with vasopressin or terlipressin have shown that somatostatin is somewhat superior to vasopressin and equivalent to terlipressin in controlling bleeding and has significantly fewer side effects; no difference in mortality was observed. Octreotide was somewhat better than vasopressin and terlipressin in controlling bleeding, with similar mortality. Meta-analysis of trials comparing somatostatin or octreotide with endoscopic sclerotherapy shows that both drugs are equivalent to sclerotherapy for bleeding control, early rebleeding and survival. Complications are much less frequent with drug treatment. Nine trials have compared endoscopic therapy with therapeutic regimens combining endoscopic treatment with somatostatin, octreotide or vapreotide. Meta-analysis show that the combined regimens increase the 5 days bleeding control rate of endoscopic treatments by over 20%, although there is no difference in mortality. Comparisons of somatostatin and octreotide with combined regimens of sclerotherapy + somatostatin and sclerotherapy + octreotide have shown that the combined regimens were better than drug treatments alone in controlling bleeding and preventing early rebleeding, while complications were significantly less frequent with drug therapy.

Abstract
BACKGROUND Anti-Saccharomyces cerevisiae antibodies (ASCA) and perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) are serological markers associated, respectively, with Crohn's disease and ulcerative colitis, whose clinical significance and possible diagnostic role are still poorly defined. AIMS (a) To evaluate the sensitivity, specificity and predictive values of isolated and combined ASCA and p-ANCA assays in a large cohort of Italian patients with inflammatory bowel disease (IBD) and (b) to assess whether their presence is associated with particular clinical features of the disease. PATIENTS AND METHODS Hundred and forty-six IBD patients (93 with Crohn's disease and 53 with ulcerative colitis) and 54 control patients were enrolled in the study. ASCA (IgA and IgG) and p-ANCA were determined by means of enzyme-linked immunosorbent assay and indirect immunofluorescence, respectively. RESULTS The specificities were excellent for both tests (ASCA in Crohn's disease, 98.1% both for IgA and IgG, and p-ANCA in ulcerative colitis, 92.5%); however, the sensitivities of both tests were low (59.1% for ASCA IgA, 44.1% for ASCA IgG, 39.6% for p-ANCA). ASCA specificity and positive predictive value reached 100% when positivity for both IgA and IgG was present. No significant association was found between the presence of a specific serological marker and patients' clinical features. CONCLUSIONS This study confirms the low prevalence of p-ANCA observed in ulcerative colitis patients from the Mediterranean area. The low sensitivity of ASCA and p-ANCA, despite their rather high specificity, renders them of little value in the screening of the general population, where the prevalence of IBD is low. However, in our series, a double positivity for ASCA IgA and IgG identifies with certainty the presence of Crohn's disease.

Abstract
BACKGROUND Enteroscopy plays a key role in the post-operative monitoring of patients with small bowel transplantation for the early detection of post-transplant complications and for the assessment of the graft's integrity. Routine surveillance enteroscopies (trans-stomal terminal ileoscopy or jejunoscopy) are invasive, may be unsafe in frail patients, and only allow incomplete exploration of the transplanted graft, which may be unsatisfactory. since the distribution of the lesions is often patchy or segmental. AIMS. To evaluate the potential of capsule enteroscopy, a new, minimally invasive technique which allows complete exploration of the small bowel. in small bowel transplant recipients. METHODS Five small bowel transplanted patients underwent capsule enteroscopy with the GIVEN endoscopy system. The results of capsule enteroscopy were compared with those of trans-stomal ileoscopy. RESULTS Capsule enteroscopy was better tolerated than ileoscopy and good quality images of the small bowel were obtained in four patients. The terminal ileum was normal both on ileoscopy and capsule enteroscopy. Mucosal changes in segments not reached by ileoscopy were detected by capsule enteroscopy in three of four patients. CONCLUSIONS Capsule enteroscopy is better tolerated than ileoscopy, allows complete exploration of the transplanted graft and can detect mucosal changes in segments not reached by ileoscopy.

Abstract
Peri-anastomotic ulcerations may occur in patients with previous abdominal surgery. They may present only with obscure GI bleeding. We report two cases in whom capsule endoscopy identified postsurgical stenoses with ulcers as the cause of obscure GI bleeding. Case 1. A 57-year-old male operated on in 1970 for a post-traumatic diaphragm hernia followed by displacement of the caecum in the upper left abdominal quadrant. Case 2. A 32-year-old female with a salpingectomy for tuberculosis (1978) followed by segmental ileal resection for intestinal obstruction. Both patients had undergone extensive work-up including bidirectional endoscopies and enteroclysis with negative results. Capsule endoscopy with the GIVEN diagnostic system was done. Ileal stenoses with mucosal ulcers in dilated prestenotic loops were observed in both cases. The capsule was retained at the stenosis site, requiring ileal resection and anastomosis. Pathology reports showed mucosal ulcers. In case 2, tuberculosis was ruled out by tissue and faecal polymerase chain reaction and culture. Ileal stenoses with prestenotic ulcerations causing GI bleeding may occur in patients with previous abdominal surgery. Capsule endoscopy may clarify the diagnosis and shorten the diagnostic work-up. However, these patients should be warned that capsule retention requiring surgery might occur.

Abstract
BACKGROUND Coagulation Factor XIII is implicated in fibrin stabilization and wound healing. Plasma levels of Factor XIII are reduced in inflammatory bowel disease patients; recently, a valine 34 to leucine polymorphism of the Factor XIII-A subunit gene with a defined protective effect against thrombosis and as yet undetermined effect on wound healing has been described. AIM To evaluate Val34Leu Factor XIII polymorphism distribution and to find possible correlations with clinical features in Italian inflammatory bowel disease patients. STUDY POPULATION A total of 152 inflammatory bowel disease patients, 90 with ulcerative colitis and 62 with Crohn's disease and 130 healthy volunteers were studied. METHODS Val34Leu polymorphism was detected by RFLP with BsaH I. Statistical analysis was performed by means of Fisher exact test. RESULTS In inflammatory bowel disease, 57.2% of patients showed the wild type status, 37.5% were heterozygous and 5.3% were homozygous for the 34Leu allele; the frequency of the mutated allele was 24.0%. In controls, 66.1% of subjects showed the wild type status, 28.5% were heterozygous and 5.4% were homozygous for the 34Leu allele; the frequency of the mutated allele was 19.7%. There was no difference in genotype distribution and prevalence of the mutated allele between inflammatory bowel disease patients and controls. CONCLUSIONS The present data do not show any differences in Val34Leu Factor XIII polymorphism distribution between inflammatory bowel disease patients and controls. The prothrombotic state described in inflammatory bowel disease patients does not depend on an altered distribution of Val34Leu Factor XIII polymorphism.

Abstract
BACKGROUND Since the recognition of tissue transglutaminase (tTG) as the target antigen of anti-endomysium antibodies, several ELISA assays using either guinea pig or human recombinant tTG have been developed. The aim of the study was to compare the behaviour of anti-tTG and anti-endomysium antibodies assays in coeliacs and in patients with chronic liver disease. METHODS 34 patients (24 women, 34.9 +/- 12.5 years) with coeliac disease and 41 with chronic liver disease (14 women, 57 +/- 11.2 years), including 19 cirrhotics, were evaluated for anti-endomysium antibodies by indirect immunofluorescence and for anti-tTG IgA antibodies by ELISA, using guinea pig liver or human recombinant transglutaminase. RESULTS The prevalences of anti-tTG and anti-endomysium antibodies were 100% in patients with coeliac disease at diagnosis, 75% and 64.3% in patients on a gluten-free diet. All liver disease patients were negative for anti-endomysium antibodies, while 11 (26.8%) were positive for anti-tTG. All these patients had liver cirrhosis and represented 57.9% of all cirrhotics. The presence of anti-tTG was associated with higher Child-Pugh scores. The use of human transglutaminase determined a reduction in the rate of positive results; however, the rate of positive anti-tTG was still 17.1% in all liver disease patients and 31.6% in cirrhotics. CONCLUSIONS Our data confirm that anti-tTG have a similar sensitivity compared with anti-endomysium antibodies assay in coeliacs. However, a high prevalence of positive anti-tTG results is observed in cirrhotic patients, even when human recombinant tTG is used. The high prevalence of positive results among cirrhotic patients is associated with more advanced liver disease.

Abstract
A 36-year-old female, presenting with jaundice, developed acute liver failure requiring orthotopic liver transplantation. On admission, none of the known causative factors for acute hepatitis, including use of drugs, were found to be present. Several days after hospitalization, the patient admitted taking therapy prescribed by a "non-traditional" physician, that she had been using for several years due to overweight and which had recently been modified with the introduction of pemoline. A considerable body of evidence exists in the medical literature showing that pemoline, which is a central nervous system stimulant, has variable hepatotoxic effects, ranging from a mild transient increase of serum transaminases to liver failure, including some lethal cases.

Abstract
Portal hypertensive gastropathy (PHG) is characterized by changes in the endoscopic appearance of the gastric mucosa, specific for portal hypertension. The identification of the elementary lesions of PHG allowed the development of a reproducible classification, defining mild and severe pictures, and the execution of a natural history study. This study showed a 80% overall prevalence of PHG in patient with cirrhosis of the liver and a correlation between duration of the disease and development of PHG. PHG has often been shown to be a fluctuating condition, thus suggesting that its pathophysiology is not only related to portal hypertension, but also to other, yet unknown, factors. Bleeding from PHG did not occur in patients with a recent diagnosis of liver cirrhosis. Acute and chronic bleeding occurred in 2.5% and 12% of patients, respectively. The death rate from acute PHG bleeding was lower (12.5%) than the death rate of variceal bleeding (39.1%). Vasoactive drugs can be used in the treatment of acute PHG bleeding. For chronic bleeding, non selective 13-blockers and, if needed, iron, are the treatment of choice. TIPS or surgical portosystemic shunt may be considered for acute or chronic PHG bleeding, if medical treatment fails. Clinical controlled trials are needed to evaluate the efficacy of these or other treatments.

Abstract
All patients with cirrhosis will eventually develop portal hypertension and esophagogastric varices. Bleeding from ruptured esophagogastric varices is the most severe complication of cirrhosis and is the cause of death in about one third of patients. The rate of development and growth of esophageal varices is poorly defined but in general seem to be related to the degree of liver dysfunction. Once varices have formed, they tend to increase in size and eventually to bleed. In unselected patients, the incidence of variceal bleeding is about 20% to 30% at 2 years. Variceal size is the single most important predictor of a first variceal bleeding episode. Several prognostic indexes based on endoscopic and clinical parameters have been developed to predict the risk of bleeding; however, their degree of accuracy is unsatisfactory. Death caused by uncontrolled bleeding occurs in about 6% to 8% of patients; the 6-week mortality rate after a variceal hemorrhage is 25% to 30%. There are no good prognostic indicators of death caused by uncontrolled bleeding or death within 6 weeks. Untreated patients surviving a variceal hemorrhage have a 1- to 2-year risk of rebleeding of about 60% and a risk of death of about 40% to 50%. The risk of bleeding is greatest in the first days after a bleeding episode and slowly declines thereafter. All patients surviving a variceal hemorrhage must be treated to prevent rebleeding. Varices can also be found in the stomach of cirrhotic patients, alone or in association with esophageal varices. Gastric varices bleed less frequently but more severely than esophageal varices. Portal hypertensive gastropathy is a common feature of cirrhosis, and its prevalence parallels the severity of portal hypertension and liver dysfunction. Portal hypertensive gastropathy can progress from mild to severe and vice-versa or even disappear completely. Acute bleeding from portal hypertensive gastropathy seems to be relatively uncommon, and less severe than bleeding from varices.

Abstract
We evaluated free plasma levels of protein S, a natural anticoagulant factor, the prevalence of anti-protein S antibodies, a possible cause of protein S deficiency, and their correlation with anti-phospholipid antibodies in 53 patients with inflammatory bowel disease (IBD) and 53 age- and sex-matched controls. Mean free plasma protein S levels (+/- SD) were significantly lower in IBD patients (0.98+/-0.32 IU/ml) than in controls (1.06+/-0.28 IU/ml) (P < 0.05); only one patient showed protein S deficiency. Specific antibodies to protein S were found in four IBD patients (7.5%) and in one control (1.9%) (P = NS). Five IBD patients (9.4%) and none of the controls showed anti-phospholipid antibodies (P < 0.06). No correlation was found between free protein S levels and anti-protein S antibodies or between anti-protein S and anti-phospholipid antibodies. In conclusion, free plasma protein S levels are slightly but significantly decreased in IBD patients. The prevalence of anti-protein S and antiphospholipid antibodies is increased in IBD patients. Anti-protein S antibodies do not appear to determine low protein S levels or to overlap with or belong to anti-phospholipid antibodies.

Abstract
Periconceptional folate supplementation reduces the recurrence and occurrence risk of neural tube defects (NTD) by as much as 70%, yet the protective mechanism remains unknown. Inborn errors of folate and homocysteine metabolism may be involved in the aetiology of NTDs. Previous studies have demonstrated that both homozygosity for the C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene, and combined heterozygosity for the C677T and for another mutation in the same gene, the A1298C polymorphism, represent genetic risk factors for NTDs. In an attempt to identify additional folate related genes that contribute to NTD pathogenesis, we performed molecular genetic analysis of folate receptors (FRs). We identified 4 unrelated patients out of 50 with de novo insertions of pseudogene (PS)-specific mutations in exon 7 and 3'UTR of the FRalpha gene, arising by microconversion events. All of the substitutions affect the carboxy-terminal amino acid membrane tail, or the GPI anchor region of the nascent protein. Furthermore, among 150 control individuals, we also identified one infant with a gene conversion event within the FRalpha coding region. This study, though preliminary, provides the first genetic association between molecular variations of the FRalpha gene and NTDs and suggests that this gene can act as a risk factor for human NTD.

Abstract
The frequency of the heterozygous 844ins68 mutation of the cystathionine beta-synthase (CBS) gene and of its association with the homozygous C677T transition of the methylenetetrahydrofolate reductase (MTHFR) gene, plasma fasting tHcy, folate and vitamin B12 levels were evaluated in 309 consecutive patients with objectively diagnosed early-onset venous (n = 200) or arterial thromboembolic disease (n = 109) recruited over 25 months in Milan (North Italy) and Naples (South Italy). The above gene polymorphisms were also evaluated in a population of 787 unmatched controls, 204 of whom--similar to patients for age- and sex-distribution--had fasting tHcy, vitamins and activated protein C resistance measured in their plasma. Moderate fasting hyperhomocysteinemia was detected in 15.5% of patients and in 5.9% of 204 controls (Mantel-Haenszel OR after stratification for type of occlusive disease and gender: 2.88; 1.48-5.32). The frequencies of the 677TT mutation of the MTHFR gene and of the heterozygous 844ins68 insertion of the CBS gene were not significantly different in the patient (19.4% and 6.9%) and the control population (16.5% and 7.8%), but the association of the two gene polymorphisms found in 3.9% of patients and in 1.1% of controls - was significantly associated with an increased risk of venous or arterial occlusive diseases (RR = 3.63; 1.48-8.91). The MTHFR 677TT mutation (RR: 6.92; 3.86-12.4) and its association with the 844ins68 insertion (RR: 21.9; 8.35-57.4), but not the isolated insertion (RR: 0.71), were more frequent in patients and controls with fasting hyperhomocysteinemia than in normohomocysteinemic subjects, irrespective of the type of occlusive disease (venous or arterial). When adjusted for determinants of hyperhomocysteinemia in the patient and the control populations (generalized linear model), fasting tHcy levels were significantly higher in subjects with association of the two gene abnormalities (24.2+/-3.8 micromol/L) than in subjects with the MTHFR 677TT mutation only (14.0+/-5.8 micromol/L, p = 0.004). Activated protein C resistance was significantly more prevalent in venous patients (9.9%) than in controls (3.9%, OR = 2.69; 1.08-6.88). Six of 21 venous patients with APC-resistance also had hyperhomocysteinemia (RR = 5.04; 0.68-37.6), but isolated fasting hyperhomocysteinemia retained statistical significance for the association with venous occlusive disease (RR = 2.84; 1.34-6.01). Heterozygosity for the 844ins68 mutation of the CBS gene is not per se a risk factor for premature arterial and/or venous occlusive diseases. However, when detected in combination with thermolabile MTHFR, it increases by almost 4-fold the risk of occlusive diseases (arterial and/or venous), by increasing the risk and the degree of fasting hyperhomocysteinemia.

Abstract
Peptic ulcer disease (PUD) has been described in the absence of Helicobacter pylori (Hp) infection, suggesting that different factors are involved in its etiopathogenesis. We investigated prevalence and characteristics of Hp-negative (Hp-) PUD in an area of Northern Italy and calculated the rate of Hp-positive (Hp+) patients with PUD in whom Hp might be coincidental and not causal. Four hundred nine consecutive patients with endoscopically diagnosed PUD were enrolled in seven hospitals. Hp infection was assessed by rapid urease test and histologic examination. The attributable risk percentages in different age groups were calculated by appropriate formulas. Of 409 patients, 31 (7.6%) were Hp- (gastric, 8.3%; duodenal, 7.6%). Age, nonsteroidal antiinflammatory drug (NSAID) consumption, and complication rates were significantly higher in Hp-than Hp+ patients with duodenal ulcers (DUs). Of the Hp-patients with DU, 58% did not use NSAIDs. In patients with Hp+ DU, the attributable risk percentage for Hp infection in patients aged <40 years, 40-60 years, or >60 years was 98%, 88%, and 66%, respectively. The prevalence of Hp- PUD was about 8%, mainly unrelated to any known etiologic factor. In about one-third of Hp+ patients with PUD aged over 60 years, Hp infection might be coincidental and not causal.

Abstract
The major cause of homocystinuria is mutation of the gene encoding the enzyme cystathionine beta-synthase (CBS). Deficiency of CBS activity results in elevated levels of homocysteine as well as methionine in plasma and urine and decreased levels of cystathionine and cysteine. Ninety-two different disease-associated mutations have been identified in the CBS gene in 310 examined homocystinuric alleles in more than a dozen laboratories around the world. Most of these mutations are missense, and the vast majority of these are private mutations. The two most frequently encountered of these mutations are the pyridoxine-responsive I278T and the pyridoxine-nonresponsive G307S. Mutations due to deaminations of methylcytosines represent 53% of all point substitutions in the coding region of the CBS gene.

Abstract
Homocystinuria due to cystathionine beta-synthase (CBS) deficiency is frequently caused by missense mutations. In this article, we report four novel missense mutations in the CBS gene: 172C-->T (R58W) linked in cis with A114V; 376A-->G (M126V); 904G-->A (E302K); and 1006C-->T (R336C). The CBS activity of the corresponding mutant enzymes expressed in Escherichia coli was greatly diminished, confirming the pathogenicity of these mutations. Western analysis showed that the R58W+A114V and M126V mutant enzymes were unstable in E. coli, while the E302K subunits were partially degraded to shorter products. Using site-directed mutagenesis we found that CBS containing either the R58W or A114V as the only mutations demonstrated 18% and 46% of normal activity, respectively. Both mutant forms of CBS were stable in E. coli. When these two mutations were expressed in cis, the resultant mutant protein exhibited activity 1.3% that of a control. All these in vitro results were in good agreement with the clinical manifestation in these patients. The Italian patient 2241, an A114V+R58W/M126V compound heterozygote, exhibited severe pyridoxine nonresponsive homocystinuria, while another Italian patient 2242, with an A114V/E302K genotype, responded to pyridoxine treatment and had a much milder phenotype. The third patient 3064, an English compound heterozygote for two severe mutations R336C and G307S, was B6 nonresponsive. This report of a ninth homocystinuric allele carrying two mutations in cis raises the possibility that double mutant alleles may be underestimated in homocystinuric patients. In this context, a search for additional mutations in cis may sometimes be necessary to establish a good genotype-phenotype relationship.

Abstract
No data are available about the amount of hepatitis B virus (HBV) genomes in liver of patients with chronic HBV infection. The aim of this study was to quantify the intrahepatic HBV DNA in hepatitis B surface antigen (HBsAg)-positive patients with either active or suppressed viral replication and in HBsAg-negative subjects with occult HBV infection. We optimized the Roche "Amplicor HBV Monitor" kit for quantifying liver HBV DNA and analyzed hepatic DNA extracts and serum samples from 19 HBs-Ag-positive and 43 HBsAg-negative individuals. Eight of the HBsAg carriers had active HBV replication, and for 3 of them we analyzed samples obtained before and at the end of 1 year of lamivudine treatment. Five hepatitis Delta virus (HDV) coinfected patients and 6 healthy HBsAg carriers had inhibited HBV activity. Among the HBsAg-negative subjects 21 had occult HBV infection and 22 had no evidence of HBV infection. The median of HBV genomes per microgram of liver DNA milliliter of serum was 34,500 to 2,620,000 in patients with active viral replication, 20,000 to 3,900, 000 before and 10,000 to 2,800 at the end of therapy in lamivudine-treated individuals, 9,800 to 600 in HDV-infected individuals, and 7,450 to 17,400 in healthy HBsAg carriers. These data indicate that cases with suppressed HBV activity, despite the very low levels of viremia, maintain a relatively high amount of intrahepatic viral genomes. This virus reservoir is likely involved in HBV reactivation, which is usually observed after stopping lamivudine treatment. Finally, the analysis of cases with occult HBV infection showed that the assay we used was able to specifically detect and quantify as few as 100 copies of viral genomes per microgram of liver DNA.

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical features and the long term evolution of patients with a well defined initial diagnosis of ulcerative proctitis. METHODS Patients with an original diagnosis of ulcerative proctitis who had been seen at any of 13 institutions from 1989 to 1994 were identified. Data on disease onset and subsequent evolution were recorded. In addition, 575 patients with more extensive disease, treated in the same centers, were used as controls. RESULTS A total of 341 patients satisfied the inclusion criteria. The percentage of smokers in these patients was slightly lower than in controls; no differences were found in the other clinical/demographic variables evaluated. A total of 273 patients entered long term follow-up (mean, 52 months). Proximal extension of the disease occurred in 74 of them (27.1%). The cumulative rate of proximal extension and of extension beyond the splenic flexure was 20% and 4% at 5 yr and 54% and 10% at 10 yr, respectively. The risk of proximal extension was higher in nonsmokers, in patients with >3 relapses/yr, and in patients needing systemic steroid or immunosuppressive treatment. Refractory disease was confirmed as an independent prognostic factor at multivariate analysis. CONCLUSIONS Proximal extension of ulcerative proctitis is frequent and may occur even late after the original diagnosis. However, the risk of extension beyond the splenic flexure appears to be quite low. Smoking seems to be a protective factor against proximal extension, whereas refractoriness is a risk factor for proximal extension of the disease.

Abstract
Endoscopic treatments for bleeding gastroesophageal varices include injection sclerotherapy, variceal obturation with tissue adhesives, and variceal rubber band ligation. Acute injection sclerotherapy remains a quick and simple technique for the control of active bleeding from esophageal varices. Although few trials have been published so far, some evidence suggests that the early administration of vasoactive drugs (somatostatin, octreotide, or terlipressin) is safe and may increase the efficacy of endoscopic treatments. Banding ligation is the optimal endoscopic treatment for the prevention of rebleeding from esophageal varices. The use of tissue adhesives and thrombin as injectates to treat bleeding fundal gastric varices and esophageal varices not responding to vasoactive drugs or sclerotherapy is promising but needs further assessment by means of randomized controlled trials. As of today, endoscopic treatments are not recommended for the primary prophylaxis of variceal bleeding.
