RESUMO
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.

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.

BACKGROUND & AIMS: The definition of failure to control bleeding agreed upon at the Baveno IV consensus meeting, included the Adjusted Blood Requirement Index [ABRI: number of blood units/(final-initial hematocrit+0.01)]. ABRI ≥0.75 denotes failure. However, timing for hematocrit measurements was not defined. The aims of this study were: (1) to assess the Baveno IV criteria performance to classify treatment success or failure to control bleeding at 5 days, (2) to determine the appropriate timing for hematocrit. METHODS: Two hundred and forty-two cirrhotic patients with gastrointestinal bleeding were independently classified by three clinical experts according to the Baveno IV criteria, by analysis of the database of a randomized trial. ABRI was calculated by using the closest hematocrit to the 5 day time point from the first trial product administration (ABRI-1) or after the latest transfusion within the 5-day period (ABRI-2). The gold standard for success/failure for 5-day control of bleeding was the clinical judgment of the three independent observers based on all the clinical and follow-up data. RESULTS: Inter-observer agreement for the final outcome assessment was 0.82 and a final consensus was obtained in 236/242 patients. Inter-observer agreement on patient classification with Baveno IV criteria was 0.70 with ABRI-1 and 0.84 with ABRI-2. c-statistics for correct patients classification were 0.86 for ABRI-1, 0.84 for ABRI-2, and 0.88 for Baveno IV criteria without ABRI. ABRI-1 caused misclassification of 27 patients and ABRI-2 of 39. CONCLUSIONS: Baveno IV criteria are accurate to assess outcome of patients with variceal bleeding. There is a substantial observer variability linked to timing of hematocrits for ABRI calculation. With the current definition ABRI does not add to the performance of the other criteria.

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.

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.

BACKGROUND: Current guidelines recommend beta-blockers for primary prevention of variceal haemorrhage in cirrhotic patients, and band ligation for patients with contraindications or intolerance to beta-blockers. However, it has been suggested that these patients may respond poorly to band ligation. AIM: We evaluated the usefulness of a strategy in which band ligation was used to treat patients with contraindications or intolerance and patients not responding to beta-blockers identified by hepatic vein pressure gradient measurement. Haemodynamic responders and patients refusing hepatic vein pressure gradient measurement were given long-term beta-blockers. METHODS: One hundred and thirty-five consecutive patients with high-risk oesophageal varices and no prior bleeding were enrolled. Twenty-five patients with contraindications (group A), 26 with intolerance to beta-blockers (group B) and 25 showing a poor haemodynamic response (Group C) underwent band ligation. Twenty-two haemodynamic responders (Group D) and 37 refusing hepatic vein pressure gradient measurement (Group E) were treated with beta-blockers. RESULTS: Median follow-up was 32 months. 12/135 patients (8.9%) bled: 3/25 (12%) in group A, 1/26 (3.8%) in group B, 0/25 (0%) in group C, 0/22 (0%) in group D and 8/37 (22.2%) in group E. Mortality was 8/135 (5.9%). CONCLUSIONS: Patients with contraindications, intolerance or not responding to beta-blockers treated with band ligation achieve protection from variceal bleeding comparable to that of good responders to beta-blockers.

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.

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.

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. In secondary prophylaxis (but not in primary prophylaxis) these drugs can be combined with organic nitrates.

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.

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.

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.

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.

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.

BACKGROUND: It is controversial whether CARD15 variants are truly associated with a more severe form of Crohn's disease. The relative role of CARD15 genotype and smoking in Crohn's disease progression is also debated. AIM: To investigate the association between CARD15 variants and history of resective surgery in patients with Crohn's ileal disease, taking into account smoking as a possible confounding factor. METHODS: We originally assessed CARD15 genotype in 239 north Italian Crohn's disease patients (mean follow-up: 10.1 +/- 8.1 years). We then focused on 193 patients with proven ileal involvement, 70 of whom (36.3%) carried CARD15-mutated alleles (G908R, R702W, L1007fs). RESULTS: Carriage of CARD15 variants was positively associated with family history and ileal-only disease and negatively associated with uncomplicated behaviour at maximal follow-up (P < 0.05). Ileal resection was the only variable independently associated with CARD15 variants at multivariate analysis (OR 3.8; 95% CI 1.6-9.2; P = 0.003). Kaplan-Meier analysis showed that ileal resection was favoured both by CARD15 variant-carriage (P = 0.01) and by smoking (P = 0.05), but smoking did not affect progression to surgery in variant carriers (P = 0.31). Thirteen of 14 (93%) patients being resection-free at 15-year follow-up, had CARD15 wild-type genotype (P = 0.01), whereas only seven (50%) had never smoked (P = 1.0). CONCLUSIONS: In summary, CARD15 variant-associated Crohn's ileitis is virtually committed to stricturing and/or penetrating disease and, eventually, to resective surgery. Smoking accelerates progression to surgery in patients with wild-type CARD15 genotype, but it seems to exert no additional effect in CARD15-variant carriers.

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.
