Primary Investigator:
Mark Silverberg, MD
Enrolment: Ongoing

Sponsor:
This initiative is funded by the National Institutes of Health in the United States and has allowed us to form an IBD Genetic Research Centre in order to build upon our previous efforts in this area.

Objective:
Objective is to identify new genes and other biomarkers that may be responsible for causing Inflammatory Bowel Disease (IBD) and understand the role of previously identified biomarkers in IBD.

Expectation: This research will lead to a better understanding of why the disease occurs, easier diagnostic tools that may avoid the need for colonoscopies, better therapies or even a cure.

Eligibility: Anyone who has a confirmed diagnosis of IBD (either Crohn's Disease or Ulcerative Colitis). Also, if you do not have IBD (i.e. Crohn's Disease or ulcerative colitis) and do not have a family history of IBD and are willing to provide a blood sample as a healthy control, your help would be greatly appreciated.

Participation:

  • Participation is very brief and involves providing us with:
    • Information regarding your family history and disease specifics
    • A small blood sample for genetic testing
    • Permission to review your medical information regarding IBD
  • You will not have to see any physicians at Mount Sinai Hospital


Notes:

  • Those with a family history of IBD may be asked for permission to contact affected individuals to participate as well.
  • Those without a family history may also be asked for permission to contact parents or other unaffected relatives (even if they do NOT have IBD) to provide a blood sample.

Status Update:

Updated as of Fall 2012 by Joanne Stempak

Participant Tally:
6000 - this includes Crohn’s Disease and Ulcerative colitis patients, parents, siblings, other relatives, and non-IBD (healthy) controls.

Genetic Analysis / Results:
We are working with the samples that we have collected. This process takes a while and is ongoing. New findings are published in scientific research articles that are publicly available (link below). Below are the titles of some the research articles we have contributed to in this area.

We would like to sincerely thank all of our study participants. This research couldn't be possible without your cooperation.
Please contact Joanne Stempak (phone: 416-586-4800 x 8399) if any of the following applies to you:

Healthy Controls:
If you do not have IBD (i.e. Crohn's Disease or ulcerative colitis) and do not have a family history of IBD and are willing to provide a blood sample for this research, your help would be greatly appreciated.

You have a scheduled colonoscopy:
If you have an upcoming colonoscopy and you are willing to fill in a food diary for 4 days prior to your colonoscopy and are willing to provide a blood sample and/or tissue biopsies obtained during your procedure, please contact us. This research is being done to help understand the role of diet in IBD by studying its effect on the gut microbiome.

You are about to start Infliximab or Humira, for the first time:
If you are about to start medical treatment with Infliximab or Humira for the first time (and have not had previous surgeries or resections for IBD) and if you're willing to participate in a research study, please contact us. This study aims to identify the factors that may affect why some patients respond or don't respond to these medical therapies. The study follows you for a period of 28-30 weeks as your are seen by your doctor for your routine medical care. This study may involve extra biopsy collections during your regularly scheduled colonoscopies, with your permission.

Sub-studies:
a. Genetic Analysis of Infliximab-treated Inflammatory Bowel Disease Patients
Tumour necrosis factor-alpha blocking agents encompass some of the available therapies for Inflammatory Bowel Disease patients. Infliximab is one of the most popular and effective amongst them and is used in both Crohn’s Disease and Ulcerative colitis. Studies show that the majority of Inflammatory Bowel Disease patients undergoing Infliximab therapy experience beneficial effects from the drug. Nevertheless, a small number of patients experience moderate to severe adverse effects to Infliximab infusions. The potential risk for patients and the high cost of Infliximab therapy demand further research into the factors pertaining to therapy response. To date, there are no reliable predictors of Infliximab therapy outcome. With this study, we aim to identify differentially expressed genes between responders and non-responders to Infliximab therapy and to examine if significant gene expression differences exist between Infliximab-treated Ulcerative colitis and Crohn’s Disease patients.

We are looking for individuals who have Crohn’s Disease or Ulcerative colitis who will be starting Infliximab treatment in the near future. For this study, please contact Joanne Stempak (phone: 416-586-4800 x 8399).

b. Mechanisms of Intestinal Inflammation Following Ileal Resection for Crohn's Disease
For many Crohn's Disease patients with small portions of severely affected terminal ileum, surgical removal of the diseased bowel and reconnection of the two ends is considered a reasonable treatment option. However, patients may experience recurrence of their disease in the future following surgery. Similar to hypotheses regarding the development of Crohn’s Disease, those relating to the recurrence of inflammation following surgery suggest that inflammation is the result of altered immunity in genetically predisposed individuals due to a combination of changes in gene expression and the microbial milieu. The aim of this study is to evaluate microbial and gene expression factors which are associated with the recurrence of small bowel inflammation following surgery for CD. This will have practical implications for evaluating which patients are more likely to rapidly recur as well as provide insight into the pathogenesis of Crohn’s Disease.

We are looking for individuals who have Crohn’s Disease and are planning to undergo Ileal Resection. For this study, please contact Joanne Stempak (phone: 416-586-4800 x 8399).
