ABSTRACT
BACKGROUND: In Crohn's disease natural history, about 80% of the patients require surgery, which is not curative: unfortunately, the disease recurs in many patients. OBJECTIVE: To investigate the role of intestinal ultrasound to predict the risk of post-operative surgical recurrence in Crohn's disease. MATERIAL AND METHODS: A total of 196 patients, with ileal or ileocolonic Crohn's disease, undergoing intestinal resection, were retrospectively enrolled. All patients underwent bowel ultrasonography 6-15 months after resection. Wall thickness at the anastomosis level was measured, and thickening >3 mm was evaluated as risk factor of long-term need for reoperation. RESULTS: Patients who have a bowel wall thickness >3 mm have an risk ratio (RR) of surgical recurrence = 2.1 [95% confidence interval (CI) = 1.12-3.74] higher than those with a thickness of ≤3 mm. The absolute incidence of new surgical intervention is 13% in patients with thickness of 3 mm, 28% in patients with thickness >3 mm, 29,1% with thickness >4 mm, 34% with thickness >5 mm, and 40% with thickness >6 mm. CONCLUSIONS: Bowel wall thickness >3 mm at ultrasound may be a non-invasive predictor of early surgical recurrence after ileo-colonic resection.

BACKGROUND: Adalimumab is used to treat ulcerative colitis, but additional effectiveness and safety data are needed. PATIENTS AND METHODS: This retrospective study considered adults with ulcerative colitis treated with adalimumab at 19 hospitals. Clinical data were collected from the start of treatment, after 2, 6 and 12 months, and at the last visit. Outcome measures of effectiveness were treatment duration, reasons for discontinuation and colectomy. RESULTS: We studied 381 patients treated with adalimumab for a median of 12.1 months. Disease activity at the start of treatment was moderate to severe in 262 cases (68.8%) and endoscopic activity was moderate to severe in 339 cases (89.0%). At week 8, clinical responses were observed in 177 cases (46.5%) and clinical remission in 136 cases (35.7%). At 12 months, remission was observed in 128 cases (33.6%). Overall, 44 patients required colectomy, and 170 patients (44.6%) were still taking adalimumab when data were collected. Variables associated with adalimumab discontinuation were concomitant steroid treatment, severe clinical-endoscopic activity at baseline, need for adalimumab intensification and drug-related adverse events. Variables associated with colectomy were concomitant steroid treatment and high baseline C-reactive protein. CONCLUSION: Adalimumab is safe and effective for the treatment of ulcerative colitis.

BACKGROUND: The objective of the study was to evaluate the diagnostic accuracy of recently developed antiglycan serological tests in clinical practice for the diagnosis of Crohn's disease. METHODS: This study was a cohort analysis of both clinical and biochemical parameters of patients with diagnosed inflammatory bowel disease compared with those in a control population. Antiglycan antibodies were determined using commercially available enzyme immunoassays. The setting was the outpatient unit of the gastroenterology department of a large, tertiary-care referral academic hospital. Participants were 214 consecutive patients, enrolled over a 5-month period, including 116 with Crohn's disease and 53 with ulcerative colitis, as well as 45 with other gastrointestinal diseases and 51 healthy controls. RESULTS: Anti-Saccharomyces cerevisiae antibodies showed the best performance (54% sensitivity and 88%-95% specificity for Crohn's disease). Among patients with negative anti-Saccharomyces antibodies, 19 (34%) had high titers of at least another tested antiglycan antibody. Anti-Saccharomyces and anti-laminaribioside antibodies were associated with disease involving the small bowel and with penetrating or stricturing phenotype. Anti-laminaribioside was significantly higher in patients with a familial history of inflammatory bowel disease. CONCLUSIONS: The new proposed serological markers are significantly associated with Crohn's disease, with low sensitivity but good specificity. About one third of anti-Saccharomyces-negative patients may be positive for at least 1 of those markers. Antiglycan antibodies appear to be associated with characteristic localization and phenotype of the disease.

Helicobacter pylori (H. pylori) is a Gram-negative bacterium, usually acquired during childhood, whose natural habitat is the gastric lumen. H. pylori is accepted as the most important cause of gastritis and peptic ulcer in humans. Nevertheless, its important role in the pathogenesis of gastric cancer as well as in several extra-gastroduodenal diseases has been confirmed. The aim of this work is to discuss, for the first time in a single article, all publications concerning H. pylori infection arising from Piedmont region, Italy, where in 1893 Giulio Bizzozero was the first who observed and described spiral organisms in the stomach of animal models. A systematic review of all publications on the management of H. pylori in adults in Piedmont, based on a PubMed and a Scopus research from 1965 to 2017 was performed. The discussed aspects are the epidemiology, the study on gastric and extragastric diseases related to H. pylori, the diagnostic methods, the treatment of H. pylori infection, and the possibility of reinfection. In conclusions, with almost 70 publications, Piedmont has proudly maintained the tradition of the father of the H. pylori.

BACKGROUND AND OBJECTIVE: Helicobacter pylori (H. pylori) infection influences duodenal inflammation. Consequently, in celiac disease and in duodenal intraepithelial lymphocytosis, the bacterium could affect the clinical-histological manifestations. The aim of this work was to evaluate the prevalence and the potential role of H. pylori infection in celiac disease and duodenal intraepithelial lymphocytosis. METHODS: H. pylori status was reviewed in 154 patients with celiac disease or duodenal intraepithelial lymphocytosis and in a control population. This retrospective study was performed at Molinette hospital, university of Torino, Italy. RESULTS: H. pylori prevalence was 36% in celiac disease patients, 19% in case of duodenal intraepithelial lymphocytosis and 41% in controls (P<0.05 vs. duodenal intraepithelial lymphocytosis). H. pylori prevalence was not significantly different between celiac disease patients with or without iron deficiency anemia (22% vs. 39%) and it was higher in patients with milder duodenal lesions: 50% in Marsh-Oberhuber classification type 1-2 vs. 33% in type 3. Celiac disease patients had a mean intraepithelial lymphocytes count greater than that of duodenal intraepithelial lymphocytosis patients (52 vs. 44 intraepithelial lymphocytes per 100 epithelial cells). Both in celiac disease and in duodenal intraepithelial lymphocytosis patients, H. pylori infection was associated with an increase in intraepithelial lymphocytes count, but this difference was not significant. CONCLUSION: H. pylori prevalence was similar in celiac disease patients and in controls and higher in patients with milder duodenal lesions. There was no association between H. pylori infection and duodenal intraepithelial lymphocytosis.

OBJECTIVES: To evaluate whether, in chronic hepatitis C-positive naive patients recruited in the routine clinical setting and treated with pegylated-interferon-α2b (Peg-IFN) and ribavirin (RBV), the sustained virologic response (SVR) is durable over the long term and whether it is associated with a decrease in liver complications and incidence of glucose abnormalities. PATIENTS AND METHODS: This was a prospective long-term follow-up study of 182 naive patients enrolled in 2001-2002 and treated with Peg-IFN and RBV and followed up to December 2010, with clinical, biochemical, and virological evaluations every 6-12 months. RESULTS: None of the 115 (63.2%) sustained responders showed late viremic relapse during the follow-up. SVR was better defined at 24 weeks (16/16 relapsers, 100%) than at 12 weeks after the end of therapy (14/16 relapsers, 87.5%). On multivariable analysis, viral genotype (odds ratio 0.16, 95% confidence interval 0.07-0.36, P=0.0001) and a greater than 20% RBV reduction (odds ratio 5.21, 95% confidence interval 1.54-17.67, P=0.008) predicted long-term response (LTR) independently. The incidence of cirrhosis was significantly higher among nonresponders (21.3%) compared with long-term responders (0.9%, P≤0.0001), but the risk of developing glucose abnormalities was not significantly reduced in long-term responders (hazard ratio 1.36, P=0.363). Hepatocellular carcinoma occurred only in three cases. CONCLUSION: SVR achieved in patients treated in the routine clinical setting with Peg-IFN and RBV is durable over the long term and LTR significantly reduces the risk of progression to cirrhosis; however, in a population with mild liver fibrosis, the clinical impact of LTR on the risk of glucose abnormalities seems negligible.

BACKGROUND: The internet has been increasingly used as a resource for accessing health-related information. A recent US survey found that approximately half of inflammatory bowel disease (IBD) patients in an IBD clinic use the internet to gather IBD-specific information. AIM: The aim of this study was to evaluate the use of the internet among Italian IBD patients. METHODS: The study was performed in seven Italian IBD referral centers by using a 28-item anonymous questionnaire. RESULTS: In all, 495 questionnaires were returned for analysis, in which 305 of 495 patients (61.6%) indicated that they are able to access the internet. A large proportion used the internet to gather health-related information (180 of 305, 59.1%) and IBD-related information (226 of 305, 74.2%). The use of the internet increased significantly with level of education (P<0.0001) and household income (P<0.0001). In addition, the use of the internet to gather IBD-related information increased significantly with the increase of disease activity and severity. CONCLUSION: Approximately half of the patients in Italian IBD referral centers used the internet to gather IBD-related information. This use positively correlated with disease activity and severity. The great majority of patients indicated that it was very important for IBD referral centers to have their own IBD-dedicated website.
