Contrast-enhanced ultrasonography: usefulness in the assessment of postoperative recurrence of Crohn's disease.
2013
Abstract Aim The aim of this study was to assess whether the contrast-enhanced ultrasonography (CEUS) can increase the value of the ultrasonography in the study of postoperative recurrence of Crohn's disease (CD). Materials and methods 60 patients with CD who had previously undergone ileocolic resection underwent prospectively both CEUS and colonoscopy within a 3-day period. The sonographic examination included evaluation of bowel wall thickness, transmural complications, colour Doppler grade and contrast-enhanced US. In addition a sonographic score was established. The capacity of CEUS to diagnose endoscopic recurrence, as well as its severity, was assessed by calculating the sensitivity, …
Accuracy of magnetic resonance enterography in the preoperative assessment of patients with Crohn's disease of the small bowel
2016
Aim to assess the accuracy of magnetic resonance-enterography in predicting the extension, location and characteristics of the small bowel segments affected by Crohn's disease. Method This is a prospective study including a consecutive series of 38 patients with small bowel Crohn's disease who underwent surgery at a specialized colorectal unit of a tertiary hospital. Preoperative magnetic resonance enterography was performed in all patients, following a homogeneous protocol, within the three months prior to surgery. A thorough exploration of the small bowel was performed during the surgical procedure, using calibration spheres, according to the discretion of the surgeon. The accuracy of mag…
Oral 5-aminosalicylic acid (Asacol) in the maintenance treatment of Crohn's disease
1992
A randomized, placebo-controlled multicenter trial was conducted to evaluate the efficacy and safety of a delayed-release formulation of 5-aminosalicylic acid (5-ASA) (Asacol; GiulianiBracco, Milan, Italy) for prevention of clinical relapse in 125 patients with inactive Crohn's disease. Patients in remission [Crohn's Disease Activity Index (CDAI) less than 150] between 3 months and 2 years were randomly allocated to receive either 800 mg 5-ASA three times daily (n = 64) or placebo (n = 61) for up to 12 months or until relapse of symptoms. Relapse was defined by a CDAI greater than 150, with a minimum increase of 100 points over the baseline value. The cumulative relapse rates were 12% in th…
Bowel perforation in Crohn's Disease: correlation between CDAI and Clavien-Dindo scores
2018
Background Many studies have elaborated different kind of activity indices for Crohn's Disesase (CD) with the endpoint of univocally measure and evaluate the gravity of its lesions and symptoms. Aim Purpose of this work is to study and define the correlation that runs between the preoperative score obtained at the Crohn's Disease Activity Index, the occurrence of postoperative complications that will require re-intervention and the severity of the postoperative lesions evaluated using the Clavien-Dindo score. Patients and methods We have collected and analyzed data from 23 patients (12 males, 11 females) that in a period that spans from 2010 to 2016 had been recovered in our Operative Unit …
Anti–Interleukin-12 Antibody for Active Crohn's Disease
2004
Crohn's disease is associated with excess cytokine activity mediated by type 1 helper T (Th1) cells. Interleukin-12 is a key cytokine that initiates Th1-mediated inflammatory responses.This double-blind trial evaluated the safety and efficacy of a human monoclonal antibody against interleukin-12 (anti-interleukin-12) in 79 patients with active Crohn's disease. Patients were randomly assigned to receive seven weekly subcutaneous injections of 1 mg or 3 mg of anti-interleukin-12 per kilogram of body weight or placebo, with either a four-week interval between the first and second injection (Cohort 1) or no interruption between the two injections (Cohort 2). Safety was the primary end point, an…
Incidence, Presentation, and Prognosis of Small Bowel Adenocarcinoma in Patients with Small Bowel Crohn's Disease: A Prospective Observational Study.
2013
International audience; BACKGROUND:: Patients with Crohn's disease (CD) of the colon are at risk for colorectal cancer and should be screened for dysplasia and cancer of the colon. Small bowel adenocarcinoma (SBA) is a complication of small bowel CD and carries a poor prognosis. However, there is no screening test for SBA in patients with small bowel CD. The aim of this study was to assess the risk and incidence of SBA in a large prospective cohort of patients with small bowel CD and to compare it with the risk of colorectal cancer in patients with CD involving the colon, recruited in the same cohort. METHODS:: In a nationwide French cohort, 11,759 patients with CD were enrolled by 680 gast…
Controlled trial comparing two types of enteral nutrition in treatment of active Crohn's disease: elemental versus polymeric diet.
1991
International audience; To determine whether an elemental diet or a polymeric defined formula diet would be more effective for treating active Crohn's disease, we conducted a prospective randomised clinical trial in 30 patients with active Crohn's disease unresponsive to steroids and/or complicated by malnutrition. They received a four to six week enteral nutrition course with either an elemental diet or a polymeric diet. Clinical remission occurred in 10 of the 15 patients on elemental diet compared with 11 of the 15 patients assigned to polymeric diet. Both groups showed similar improvements in nutritional status, biological inflammation, alpha 1 antitrypsin clearance, and colonoscopic le…
Wireless Capsule Endoscopy in a Patient with Obscure Occult Bleeding
2002
A case of obscure/occult bleeding in a 39-year old man with a 7-year history of chronic fatigue and iron-deficiency anemia is presented here. Esophagogastroduodenoscopy, push enteroscopy, ileocolonoscopies, and a magnetic resonance imaging small-bowel follow-through did not reveal any abnormalities. Multiple inflammatory lesions with fibrin-covered ulcers and petechial bleeding in the area of the lower jejunum and ileum were diagnosed only with capsule endoscopy. One ulcer located near the ileocecal valve was then biopsied during a repeat ileocolonoscopy, and the histology showed signs of Crohn's enteritis. The further treatment approach was changed, with medical treatment being initiated a…
Perianal Fistula-Associated Carcinoma in Crohn's Disease: A Multicentre Retrospective Case Control Study.
2021
Abstract Background and Aims Carcinoma associated with perianal fistula in Crohn’s disease is a pending threat for patients. This study aimed to improve understanding and facilitate development of diagnostic and therapeutic strategies. Methods A retrospective case-control study was conducted at four German hospitals. The analysis included 40 patients with proven malignancy associated with perianal Crohn’s fistulas and 40 randomly selected controls with fistulizing perianal Crohn’s disease. Differences between groups were analysed and multivariate calculations were performed to describe risk factors for oncological outcomes. Results Histology revealed adenocarcinoma in 33/40 patients and squ…
Infliximab in the treatment of Crohn's disease: Predictors of response in an Italian multicentric open study
2005
Abstract Background. Almost 20% of patients with active Crohn's disease are refractory to conventional therapy. Infliximab is a treatment of proven efficacy in this group of patients and it is not clear which variables predict a good response. Aims. To evaluate the role of infliximab looking at the predictors of response in a large series of patients with Crohn's disease. Patients and methods. Five hundred and seventy-three patients with luminal refractory Crohn's disease (Crohn's Disease Activity Index (CDAI) > 220–400) (312 patients) or with fistulising disease (190 patients) or both of them (71 patients) were treated with a dose of 5 mg/kg in 12 Italian referral centres. The primary endp…
