This study is being done to determine whether the rates of birth defects, miscarriages, premature births and other outcomes in women with inflammatory bowel disease (IBD) taking azathioprine/6MP or biologic therapy or small molecules are different from those among IBD-affected women not taking these medications. Participants will be asked to give blood samples to assess drug levels during pregnancy and after birth. They will also be asked to answer questionnaires about their and their baby's health.

The goal of the DDRCC Biorepository is to collect human samples and health information to store for future research. Samples to be collected are blood, tissue (gastrointestinal, liver, pancreas and/or lymph nodes), stool, and cheek swabs. Participants may be eligible to enroll if scheduled for a clinical visit or surgical procedure during which these samples could be collected.

This research study is being conducted to gather information about patients with inflammatory bowel disease (IBD) to better understand their knowledge and preferences about self-help resources and learn how to help patients better manage their disease. Participation in this study will involve signing a research consent form, completing questionnaires, and the opportunity to participate in self-help resources. Some participants may be offered the opportunity to participate in a virtual focus group, as well. Participation in the study will last approximately 3 months.

The goal of this study is to collect health information from adults with IBD to better understand the disease and ultimately improve care for participants and other adults living with IBD. Participation in this study is voluntary. If a subject agrees to be in this study, we will collect information electronically (through a web-based platform called IBD Qorus) from the subject and the subject's IBD health care provider about their IBD health information.

Approximately 50 sites across the U.S. are currently participated in this study. The study is sponsored by the non-profit Crohn's and Colitis Foundation.

With the collected medical data, the study will focus on the strategy of identifying goals (or targets) of IBD care, developing a strategy to reach these goals, and then continuously evaluating progress of achieving these targets and modifying the treatment plan.
