Active clinical trials for "Crohn Disease"

The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).

The investigators intend to establish a prospective registry of patients diagnosed with inflammatory bowel disease at Parirenyatwa hospital in Harare, Zimbabwe. The study will periodically collect data on disease phenotype, disease course, and clinical management, and will biobank stool specimens and germline DNA. One relative, and an individual from the same neighbourhood will be also be recruited for a nested case-control study into risk factors of inflammatory bowel disease in this population.

Patients with chronic inflammatory diseases (CID) followed in gastroenterology, dermatology and rheumatology have physiopathological, epidemiological and therapeutic focal points. The pathologies concerned are inflammatory bowel diseases (IBD - Crohn's disease [MC] and ulcerative colitis [RCH]), chronic inflammatory skin diseases (psoriasis or Verneuil's disease) and chronic inflammatory rheumatic diseases (rheumatoid arthritis [RA] and spondyloarthritis [SpA] including psoriatic arthritis [PsA]). Presenting one of these diseases is associated with a higher risk of having a second inflammatory pathology, whether the latter is ophthalmological, dermatological, rheumatological or gastroenterological. An association of extra-articular manifestations is observed in 10 to 30% of patients with SpA, and an association of extra-intestinal manifestations is observed in approximately 30% of patients with IBD. No common database for chronic systemic inflammatory diseases currently exists in France.

As a consequence of chronic relapsing inflammation in Crohn's disease (CD), progressive bowel damage and scarring occurs in affected regions of intestine. This damage often leads to narrowing, or stricturing of the bowel lumen, and even complete bowel obstruction. Stricturing CD is thought to be a major contributor to penetrating complications including abscesses and fistulae. Depending on the severity and clinical significance of fixed strictures, treatment options include either endoscopic balloon dilatation (EBD), or surgery with either resection or stricturoplasty recommended on a case-by-case basis. EBD has been shown to be a safe alternative to surgery in management of CD strictures. While the short- and medium-term clinical outcomes of EBD have been well described, less well studied is the impact of relieving Crohn's strictures on the inflammatory load proximal to the stricture. The restricted flow of fecal contents through a stricture creates a region of relative stasis in the bowel loops immediately proximal to the stricture, appreciated at times by pre-stenotic dilatation on cross-sectional imaging. This stasis fosters localized bacterial overgrowth and worsening dysbiosis in these bowel loops. The investigators hypothesize that improvement of fecal flow by way of successful balloon dilatation of a CD stricture, could independently reduce the inflammatory burden, not only in the stenotic segment but also in the proximal loop of bowel.

Patients with Inflammatory Bowel Disease (IBD) have higher rates of sexual dysfunction than the general population. We offer an educational program on IBD including a specific discussion on intimacy and sexuality for IBD patients. Our objective is to investigate the benefit of this intervention on sexual function in patients with IBD.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD). Like other chronic diseases, patients with CD may be affected by other diseases called comorbidities. The prevalence of comorbidities in IBD patients ranges from 30 to 70 %. Unlike other chronic diseases, there is currently no CD-specific tool to assess the impact of comorbidities on patients' lives in order to take appropriate medical measures. Several clinical indexes have been developed for the study of comorbidities, including the Charlson index and the Groll index, which are widely used. The disadvantage of these indexes is that they are not adapted to patients with CD. The primary objective of this study is to develop and validate a clinical index to evaluate the impact of comorbidities on disability in patients with CD.

The aim of the study is to generate novel minimally-invasive serum protein signatures and biomarkers in children and adolescents with Crohn's Disease (CD) that correlate with and can predict and monitor patients who will have a prolonged response to Infliximab so that personalized medicine can be applied to patients with CD.

This is a prospective, non-interventional registry and biorepository for patients with IBD. Longitudinal follow-up data is collected from both patients and their treating gastroenterologist during routine clinical encounters. The biorepository will consist of prospective collection of blood samples, tissue samples, and fecal samples for research purposes, while the participants are undergoing a clinically-indicated procedure (i.e. venipuncture for routine tests, IV catheter placement, and/or endoscopy). Participants may choose to provide any or all of the aforementioned information and/or samples.

In this study, participants with complex fistulizing conditions will be treated with surgical interventions according to their clinic's standard practice. The aim of the study is to generate real-world evidence on standard of care for surgical interventions and related outcomes when treating complex fistulizing conditions. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.

Rates of inflammatory bowel disease (IBD) are increasing rapidly in children and young people, and targets for management are becoming more demanding, with better control of disease to prevent complications, cancers and surgeries. This project "Non-Invasive Monitoring Through Bowel Ultrasound in Paediatric Inflammatory Bowel Disease" or NIMBUS study will aim to explore the possibility of using ultrasound to examine inflammation in this group. Monitoring inflammation in this population currently is done with regular endoscopy (camera tests) and/ or MRI enterography scans which are invasive, can be uncomfortable, expensive and may have long waiting lists. These studies also require bowel prep, in the form of laxative medicines which can be distressing and cause time off from school. Direct visualisation through ultrasound could allow better monitoring of disease, and is quick, accurate, non-invasive and relatively low-cost. This could also allow for more appropriate medication use and a decrease in over/under use of medicines. This study will aim to recruit 50 children and young people with inflammatory bowel disease. Each child will have an ultrasound scan after enrolment and the investigators will use the information from these scans, as well as routine blood tests (already taken in normal care) and follow up medical information to explore the use of ultrasound in this group. The investigating team will aim to contribute to the global discussion around this topic and if results are positive will aim to improve monitoring for this population managed at the Noah's Ark Children's Hospital for Wales.
