Bacteria-specific T-cell clones are selective in their reactivity towards different enterobacteria or H. pylori and increased in inflammatory bowel d…
1996
In the present study the authors investigated the T-cell response to different enterobacteria or Helicobacter pylori and tested the hypothesis that the frequency of bacteria-specific T cells is increased in the intestine of patients with active inflammatory bowel disease (IBD), i.e. Crohn's disease (CD) and ulcerative colitis (UC). The analysis of a large panel of T-cell clones (Tc) (n = 888) from peripheral blood, non-inflamed and inflamed intestine from IBD patients and control individuals shows that both peripheral blood and intestinal T-cell clones were selectively stimulated by either Salmonella typhimurium, Yersinia enterocolitica 03, Escherichia coli or Helicobacter pylori sonicates,…
Telemonitoring of Crohn's Disease and Ulcerative Colitis (TECCU): Cost-Effectiveness Analysis.
2019
Background Although electronic health interventions are considered safe and efficient, evidence regarding the cost-effectiveness of telemonitoring in inflammatory bowel disease is lacking. Objective We aimed to evaluate the cost-effectiveness and cost-utility of the Telemonitorización de la Enfermedad de Crohn y Colitis Ulcerosa (Telemonitoring of Crohn’s Disease and Ulcerative Colitis [TECCU]) Web platform (G_TECCU intervention group) for telemonitoring complex inflammatory bowel disease, compared with standard care (G_control) and nurse-assisted telephone care (G_NT intervention group). Methods We analyzed cost-effectiveness from a societal perspective by comparing the 3 follow-up method…
Inflammatory Bowel Disease as a Precondition for Stroke or TIA: A Matter of Crohn's Disease Rather than Ulcerative Colitis.
2020
Abstract Background As a chronic systemic inflammation may be associated with an increased risk of vascular events, the aim of the present study was to assess the incidence of stroke and transient ischemic attack (TIA) in patients with inflammatory bowel disease over a period of 15 years. Methods This cohort study included patients for whom the initial diagnosis of an inflammatory bowel disease (IBD) (Crohn's disease: CD and ulcerative colitis: UC) was documented anonymously between 2000 and 2015 in 1,262 general practices in Germany. IBD patients were matched to patients without IBD using propensity scores based on age, sex, physician, co-diagnoses and co-therapies. Cox regression models w…
Management of ulcerative colitis in a real-life setting: An Italian multicenter, prospective, observational AIGO study
2019
Abstract Background No data are available on the variability in the clinical management of ulcerative colitis (UC) patients by Italian gastroenterologists. Therefore, improving the standards of UC care as provided by the National Welfare Clinical Path (PDTA), in accordance with the European Crohn’s and Colitis Organization (ECCO) guidelines for UC, is not easy. Aims To assess the management of UC by Italian gastroenterologists in a real-life setting taking into account its variability. Methods This prospective, cross-sectional, observational study included IBD-specialized gastroenterologists (GSIBDs) and general gastroenterologists (GGs) working in Italian public hospital units. Consecutive…
Infliximab three-dose induction regimen in severe corticosteroid-refractory ulcerative colitis: Early and late outcome and predictors of colectomy
2014
Abstract Background Infliximab is effective as rescue therapy in severe corticosteroid-refractory ulcerative colitis. The optimal dose regimen and the long term benefits are not well defined. The aim of the present study was to evaluate short- and long-term colectomy rate in a cohort of patients with severe corticosteroid-refractory ulcerative colitis who received a three-dose infliximab induction regimen. Methods One hundred and thirteen patients admitted to 11 Italian IBD referral centres and treated with infliximab according to an intention to treat three-dose regimen were included. The co-primary endpoints were 3- and 12-month colectomy rate. The secondary end-points were the overall co…
Two-year effectiveness and safety of golimumab in ulcerative colitis: An IG-IBD study
2020
Abstract Background Few data exist regarding the long‐term effectiveness of golimumab in ulcerative colitis. No data have been reported on real‐world continuous clinical response. Objective This study aimed to describe the long‐term outcomes in a large cohort of patients on golimumab who had ulcerative colitis. Methods Consecutive patients with active ulcerative colitis, started on golimumab, were enrolled and prospectively followed up. The primary end point was to evaluate the long‐term persistence on golimumab therapy. Results A total of 173 patients with ulcerative colitis were studied. Of these, 79.2% were steroid dependent, and 46.3% were naïve to anti‐tumour necrosis factor alpha agen…
Risk factors for locally advanced cancer associated with ulcerative colitis: Results of a retrospective multicentric study in the era of biologics
2020
Abstract Background Patients affected by ulcerative colitis (UC) are more likely to develop colorectal cancer, and are often diagnosed with lymph node involvement (N+) at surgery. Aim To identify the risk factors for N+ cancer in UC patients. Methods Patients undergoing surgery from 2001 to 2018 in six European tertiary centres were included. N+ patients were compared to the control group (N−) for clinical variables. The evaluation of risk factors for N+ was assessed using univariate and multivariable logistic regression analyses. Results A total of 130 patients were included. Median duration of disease was 21 years (1–52). Forty patients (30.8%) were N+ at surgery. Eighteen (13.8%) develop…
Prospective study of morphologic and functional changes with time in the mucosa of the ileoanal pouch: functional appraisal using transmucosal potent…
1998
PURPOSE: This study was undertaken to investigate the morphologic and functional changes with time in the mucosa of the ileoanal pouch. METHODS: A morphologic study by histopathologic analysis, mucosal morphometry, and mucin histochemistry and a functional study by analysis of transmucosal potential difference were performed in 27 patients with an ileoanal J-pouch after restorative proctocolectomy for ulcerative colitis. In 19 patients with a normal ileoanal pouch, two prospective follow-up analyses were performed after median functional pouch times of 14 and 39 months. We also evaluated eight patients with the diagnosis of pouchitis (median follow-up, 52.5 months). RESULTS: In the normal i…
Mycophenolate mofetil is a valid option in patients with inflammatory bowel disease resistant to TNF-α inhibitors and conventional immunosuppressants.
2017
Abstract Background Few studies investigated the role of mycophenolate mofetil in inflammatory bowel disease, and none of them had specifically focused on patients with previous multiple intolerances and/or nonresponses to conventional immunosuppressants and biologics. Aims To evaluate clinical benefit and tolerability profile of mycophenolate mofetil in patients with inflammatory bowel disease and limited treatment options. Methods All consecutive patients with previous multiple intolerances and/or nonresponses to immunosuppressants and biologics who started an off-label treatment with mycophenolate mofetil from January 2014 to February 2016 were entered in a prospectively maintained datab…
A Web-Based Telemanagement System for Improving Disease Activity and Quality of Life in Patients With Complex Inflammatory Bowel Disease: Pilot Rando…
2018
Background: The reported efficacy of telemedicine in patients with inflammatory bowel disease (IBD) is inconsistent among studies, and data for complex IBD are lacking. Objective: We aimed to evaluate the impact of remote monitoring using a Web system—Telemonitorizacion de la Enfermedad de Crohn y Colitis Ulcerosa or Telemonitoring of Crohn’s Disease and Ulcerative Colitis (TECCU)—as compared to standard care and telephone care on health outcomes and health care in patients with complex IBD. Methods: We performed a 3-arm randomized controlled trial. Adult patients with IBD who received immunosuppressants and biological agents were recruited from the IBD Unit of a tertiary university hospita…
