Filter by:Small bowel ultrasound (SBUS) is emerging as a well tolerated, non-invasive, radiation free, low cost measure to assess inflammatory bowel disease (IBD), and is being used as first-line imaging in Europe. SBUS findings have been shown to correlate with endoscopic findings, and a small number of recent studies have looked at change in bowel wall thickness (BWT) in response to anti-tumor necrosis factor (anti-TNF) therapy. However, the use of SBUS to detect response to anti-TNF therapy has not been tested in pediatric patients. The purpose of this study is to apply the use of SBUS to pediatric patients with Crohn's disease and to assess response to treatment with infliximab. The investigators will also measure C-reactive protein and fecal calprotectin at baseline, and additionally measuring IFX levels and anti-infliximab antibodies (ATI) at week 14 to assess change in biochemical response to infliximab treatment, as well as correlation between these markers with changes in patient reported outcomes via a weighted pediatric Crohn's disease activity questionnaire (wPCDAI) and changes in BWT. This study is novel in that it will be the first study in pediatric patients to use SBUS to assess response to IFX therapy, and will also be the first study to correlate SBUS findings with therapeutic drug monitoring (TDM). This study has the potential to propagate the use of SBUS in the pediatric population, as the use of TDM in concert with small bowel imaging post-induction will allow the investigators to tailor therapy early in the treatment course.
The primary objective of this study is to determine whether pediatric Crohn Disease (CD) patients in long-standing remission remain in remission longer after stopping medications if they follow the Crohn's Disease Exclusion Diet (CDED). The hypothesis is that subjects on the CDED will have longer time-to-relapse as opposed to those on an unrestricted diet.
The family of inflammatory/autoimmune systemic diseases (IAD) form a continuum from pure inflammatory diseases to pure autoimmune diseases, encompassing a large panel of inflammatory diseases with some autoimmune components, and vice versa. Cross phenotyping of patients with IAD should be heuristic and help revise the nosography and the understanding of these diseases.
For public health purposes disability is becoming increasingly important as an outcome measure. Despite this, there are few data on the effectiveness of adalimumab on disability outcomes in patients with immune-mediated inflammatory diseases (IMIDs), particularly in the Phase IV setting. There are even less data available in New Zealand, which did not have the opportunity to participate to a major extent in large, multinational, Phase III pivotal studies of adalimumab in IMIDs. The World Health Organisation Disability Assessment Schedule (WHODAS) 2.0 is a simple, validated, free and easy-to-use generic assessment instrument for health and disability. It is applicable across cultures, in all adult populations. It is a responsive measure that can show what difference a treatment makes. Results from study of effect of adalimumab on WHODAS scores and other patient-reported outcomes (PROs) of work activity and well-being will be of interest to a variety of stakeholders in the healthcare system including patients, healthcare practitioners and payers.
Stem cell transplantation has emerged as a relatively popular treatment that can help to regulate immunity, repair injury, and control inflammation. Several studies have used autologous stem cells or adipose-derived stem cells to treat Crohn's disease and its associated complications, and have achieved good efficacy. Thus far, the use of umbilical cord mesenchymal stem cells (UC-MSCs) to treat Crohn's disease has rarely been reported. In this study, UC-MSCs were used to treat patients with hormone-controlled Crohn's disease. We observed the disease control conditions, corticosteroid dosage changes, and treatment-related adverse reactions.
Current evidence suggests that the gut microbiota and dietary influences are as important as genetics in the aetiology of Crohn's disease (CD). We have recently shown that disease improvement, following treatment with Exclusive Enteral Nutrition (EEN), coincided with changes in the gut microbiota. The main purposes of this study are: a) to explore whether the gut microbiota changes we observed in this previous study in children with CD during EEN are disease specific or not, and b) to develop a novel food-based diet (Crohn's Disease TReatment-with-EATing/CD-TREAT diet) which will induce changes to the metabolic activity and bacterial composition of the gut microbiota of healthy people, similar to those seen on EEN, the first-line treatment for active paediatric CD. This study will produce high quality scientific evidence to move the CD-TREAT diet towards a preliminary clinical trial in patients with CD which is currently inappropriate and unethical to carry out in people with active CD undertaking contemporary medical treatment.
The purpose of this study is to evaluate endoscopic remission at Week 26 as assessed by ileocolonoscopy.
Vedolizumab is a new medication being used for the treatment of Crohn's disease and Ulcerative colitis. It works by blocking specific white blood cells (alpha 4-beta7 lymphocytes) from migrating to areas of inflammation in the gastrointestinal tract. Previous studies have shown that patients who have previous exposure to another type of medication for Crohn's disease and Ulcerative colitis (anti-TNF medications) do not respond to vedolizumab as well as those who have never been exposed. This study will investigate biologic markers in the blood and tissue the help identify possible reasons for this difference.
The daily requirement of threonine, an essential amino acid, will be evaluated in healthy adult males and in adult males with Crohn's Disease or ulcerative colitis using the indicator amino acid oxidation (IAAO) method. Participants will consume specially formulated diets with varying levels of threonine.
