Active clinical trials for "Crohn Disease"

Patients with Crohn's disease (CD) have an increased risk of small bowel adenocarcinoma (SBA). Long duration of CD is the main risk factor. SB dysplasia has been associated with SBA in 20% of cases, always described in diseased sites. The progression to neoplasia and natural history remains unknown but progression of inflammation to dysplasia and then to adenocarcinoma is suspected. As for surveillance recommendations for colorectal carcinoma in long standing inflammatory colonic disease, endoscopic screening of SB could be proposed in CD patients with risk factors of SBA. No study can be found in literature. The investigators propose a multicenter exploratory open study on prospective cohort of CD patients with high risk of dysplasia or cancer. The goal is evaluate the rate of dysplasia and adenocarcinoma detected by enteroscopy with biopsies in a high risk CD population

Patients with inflammatory bowel disease (IBD) will be assessed for immunologic response to pneumococcal vaccination. Patients with IBD meet criteria as outlined by the Centers for Disease Control (CDC) for pneumococcal vaccination, yet the investigators have found that pneumococcal vaccination in this population is under-utilized. It is unknown whether or not IBD or IBD-related medications impact the immune response to this recommended vaccine. Three groups of 25 patients each will be recruited. The first group will consist of outpatients with IBD who are receiving infliximab (Remicade TM) while on concommitant immunosuppressive therapy (with either 6MP, azathioprine, or methotrexate). This group is intended to represent a common 'heavily immunosuppressed' patient group with IBD. The second group will consist of patients with IBD seen in our outpatient clinic who are not on any immune-suppressive medications. These patients meet CDC criteria for vaccination by virtue of having a chronic medical illness. The third group will consist of healthy age-matched (to the first group) controls. After obtaining informed consent, patients will be screened with baseline lab tests including testing for antibodies against pneumococcus. At the baseline visit, patients will also undergo a brief medical history, physical examination, and assessment of their IBD disease activity. Included patients will then undergo a one-time intramuscular vaccination with 23-valent polysaccharide pneumococcal vaccine (Pneumovax TM). One month later, subjects will return for a blood draw to assess for response to pneumococcal vaccination.

A randomized, placebo-controlled pilot study to determine endoscopic recurrence of Crohn's disease 12 months after curative, resective ileal or ileocolonic surgery in patients receiving post-operative infliximab or placebo

Prospective study to compare in a blinded fashion four different diagnostic modalities to detect active small bowel Crohn's disease: a) colonoscopy with ileoscopy; b) small bowel follow through; c) capsule endoscopy; and d) computed tomography enterography.

The purpose of this study is to determine whether Non-invasive endoscopic procedures (pillcam colon capsule endoscopy, PCCE) and non-ionizing radiological modalities (MR enterocolonography, MREC and ultrasound, US) - offer a sufficiently high diagnostic validity in patients with suspected CD compared to the traditional invasive approach using ileocolonoscopy with biopsies as first line diagnostic modality

Diagnostic validity of [18F]FSPG for assessing disease activity will be assessed in subjects with inflammatory bowel disease.

Single centre prospective pilot study on surgery for Crohn's disease (CD). CD universally recurs after surgery and no technique so far has been proven to reduce recurrence. The investigators speculate that a different surgical technique, based on pathophysiology of the disease may prove successful in reducing rates of recurrence. Consecutive CD patients with a surgical indication for ileocolic disease will receive an extended procedure including a lymphadenectomy (Pathophysiologic excision for Crohn's disease). Primary outcome will be endoscopic recurrence rates at 6 and 12 months from surgery.

To validate an updated version of CapsoCam® SV-3 Endoscopy System brand name CapsoCam Plus™) with respect to the reproducibility of the system to capture and download small bowel images in a manner consistent with the predicate CapsoCam® SV-2 and SV-3 capsule endoscopy systems.

This study is a randomised open label study, comparing the FIT diet with standard diet in patients with Crohn's disease treated with biologic therapy.

This randomised, controlled study aims to evaluate the impact of endoscopic assessment, and adjustment of therapy, after surgery in patients with Crohn's disease. The primary endpoint is the severity of endoscopic recurrence. In addition, tissue will be collected for microbiological and immunological analysis.
