An Audit of Patients With Crohn's Disease Treated With Infliximab (P06066)

Crohn's Disease

The aim of this study is to quantify how infliximab therapy is being used in the UK and the consequent impact on health care resources, which will help to inform budget holders and payers on the costs associated with the treatment of Crohn's Disease.

Endocytoscopy for in Vivo Determination of Mucosal Inflammatory Cells and Intestinal Disease Activity...

Crohn´s DiseaseUlcerative Colitis

Precise activity assessment of inflammatory bowel disease (IBD) is essential to determine the extent and severity of the disease for further specific therapy. Nevertheless, despite ongoing developments in the field of gastrointestinal endoscopy, the final diagnosis still relies on the interpretation of histopathological features of intestinal biopsies taken during the endoscopic examination. Recently, endocytoscopy (EC) was introduced as a new endoscopic imaging modality, enabling microscopic imaging within the mucosal layer of the gut at a magnification level of up to 1400-fold.

Significance of Ficolin 2 in the Determination of Serological Activity in Chronic Inflammatory Bowel...

Crohn Disease

Background Determining disease activity in IBD is sometimes difficult and, to be accurate, requires endoscopy. The serum marker CRP has not proven sufficiently valuable as a marker for IBD specific inflammation. As an alternative, so far fecal calprotectin appears to be more reliable and has shown a certain value as predictive marker. Our preliminary data now show, that the serum concentrations of ficolin-2 are significantly higher in CD patients with a HBI >3. Ficolin-2 is a lectin and acute phase protein produced in the liver and, like MBL, can activate the lectin pathway of complement. Unlike MBL, deficiency for ficolin-2 was not detected in our patient cohort, nor could we find functional deficiencies for ficolin-2 (paper submitted). Study Aims The study is aimed to substantiate the data from our pilot study which shows that ficolin-2 is significantly increased in CD patients during inflammation. Therefore, the study will measure ficolin-2 concentrations in a sufficiently large patient group to obtain enough statistical power and to compare these results with the endoscopic disease score (SES-CD) and CRP and calprotectin values. Statistical analysis of the data will show us if ficolin-2 is a reliable and easy to obtain new marker for active inflammation in CD. Study Design Based on a power analysis 112 CD patients and 112 UC patients need to be analyzed. They will be recruited from Bern, Basel and Lausanne. Only patients with routine endoscopy will be included in the study and will be scored by SES-CD. Blood samples will be collected at the day of endoscopy. Stool sample will be collected within the same week of endoscopy. Calprotectin and CRP concentrations will be determined by routine diagnostics, ficolin-2 concentrations will be determined by ELISA in our laboratory. Finally, all data will be statistically analyzed.

Plasma Citrulline Concentration in Tropical Enteropathy

Malabsorption SyndromesGranulomatous Enteritis3 more

Citrulline is an amino acid produced in the intestine and in the liver, but the liver does not contribute significantly to circulating citrulline concentrations. The intestine is thus the only organ that normally releases significant amounts of citrulline into the blood stream. The investigators have designed a study looking at the value of measuring plasma citrulline concentration in patients with tropical enteropathy of mixed HIV status. The focus will be on the ability of the intestine to sustain the individual concerned from a nutritional standpoint. The investigators hypothesise that plasma citrulline concentration is a marker of small bowel absorptive integrity and an appropriate surrogate for HIV related enteropathy.

Monroe County Inflammatory Bowel Disease (IBD) Registry

Inflammatory Bowel DiseaseCrohn's Disease1 more

This phase is to register all subjects in Monroe County, New York with Inflammatory Bowel Disease (IBD) not already included to update the database for years 1990-2003. This will give us a truly population based study which will add to our knowledge of IBD epidemiology, allowing us to compare our rates with the rest of the world. We will be able to provide accurate incidence data from 1980 to 2000, and point prevalence from 12/31/2000. It will have special significance because of the relatively stable Monroe County population prior to 2000 (population in 1970=711,917; population in 2000 = 735,343).

Epidemiology of IBD in Hong Kong: An Inception Cohort and Follow up Study

Inflammatory Bowel DiseasesCrohn Disease1 more

Crohn's disease and ulcerative colitis are inflammatory disorders of the gut which cause major life-long disability. They affect males and females, with the commonest age of onset in childhood, teens and early adult life. Previously restricted almost exclusively to the West, these conditions are becoming much more common in Asian countries, including Hong Kong - the cause of this dramatic change is unknown. The cause of IBD is widely accepted as relating to the mucosal immune response to stimulation from the gut bacteria, on a background of genetic susceptibility. The bacteria and other organisms in the gut play a central role in the development of IBD in the West. However it is unknown if the gut bacteria differ between Chinese patients with IBD and non-IBD (healthy subjects) in Hong Kong, and whether it is affected by diet or changes in diet. A family history is the largest risk factor for the disease. More than 50 different genes associated with IBD have recently been identified in the West and preliminary data showed that Chinese patients have a different genetic profile to Western populations. This project aims to explore the true incidence of IBD in Hong Kong and factors that may be contributing to, or causing, the increase of IBD in Hong Kong. Investigators aim to investigate the number of new cases of IBD within a five year period and factors that may account for the cases. Investigators will also study the choice of medical therapy, quality of life and quality of health care in patients with IBD.

Self-Management Assistance for Recommended Treatment (SMART) Portal

Crohn's DiseaseUlcerative Colitis2 more

The purpose of the study is to develop, evaluate, and optimize an interactive website (the SMART portal). The SMART portal will use IBD-specific and general assessments and interventions to reduce the burden of common barriers to treatment adherence and enhance self-management skills. This study aims to build and revise the SMART portal according to feedback and testing from participants.

Home basEd faecaL calProtectin Measurements Predicting Adalimumab Induction Destiny

Crohn DiseaseColitis1 more

Recently a smartphone application IBDoc® was developed to enable patients to measure faecal calprotectin at home in an easy way. In this HELP-AID trial we want to evaluate the value of these home based IBDoc® faecal calprotectin measurements in predicting short- and mid-term outcome to ADA induction therapy in patients with moderate-to-severe IBD. Patients known with moderate-to-severe CD and ulcerative colitis starting ADA therapy will be asked to participate in this study. They will be asked to collect a stool sample at 3 different time points (week 0, 4 and 8). This faecal sample needs to be loaded on a test cassette with an extraction device. In a second step, the patient can turn his smartphone into an easy to use test cassette reader by taking a picture and using the CalApp® which is based on an immunochromatographic test. Finally, the CalApp® will transmit the test results securely to the health care professional. In this study we want to evaluate the predictive value of absolute and relative faecal calprotectin values measured by IBDoc® on clinical, biological and endoscopic outcome at week 12. Furthermore, we want to evaluate the correlation between IBDoc® and classical ELISA measurements of faecal calprotectin, and the convenience of this system to the patient and the health care professional.
