• Map and compare the neoplasia-associated epigenetic field in IBD-CRN, sporadic CRN and controls.  
• Measure sensitivity of DNA methylation for the detection of synchronous IBD-CRN as a complement or alternative to histologic diagnosis of dysplasia on random biopsies. 
• Measure the density and types of lymphocytes infiltrating IBD-CRN tumors, sporadic tumors and the epigenetic field. 

This will be a prospective study of patients with IBD at Mayo Clinic initially in Jacksonville with possible subsequent extension to other Mayo sites.  We will evaluate the immunogenicity of commercially available COVID-19 vaccines and compare vaccine response among the groups based on their immunosuppressive regimens.  We will divide the immunosuppressive regimens into presumed high vaccine responders Group A and presumed low vaccine responders Group B. We will also assess for adverse reactions to the vaccine and compare with the reported rates in the clinical trials that led to approval of these vaccines.

Understanding of how best to treat inflammatory bowel disease (IBD) has evolved over the last ten years. Evidence now suggests that the most effective therapy early in the course of Crohn's disease (CD) and ulcerative colitis (UC) involves the use of immune suppressing medications such as the anti-Tumor Necrosis Factor (anti-TNF) agents infliximab, adalimumab, and certolizumab. However, many CD and UC patients still ultimately require surgery despite the use of these medications. Side effects of the anti-TNF agents include increased risk of infections due to their effect on the immune system. Little is known about how use of these medications ...

Primary Aim

            We aim to evaluate: 1) the correlation between patient-reported rectal bleeding and stool frequency and health-related quality of life focused on fatigue, depression and anxiety, and work productivity; and 2) the correlation between the severity of endoscopic inflammation and health-related quality of life focused on fatigue, depression and anxiety, and work productivity.

Secondary Aims

We also aim to evaluate the correlation between the combination of clinical/PRO and the severity of endoscopic inflammation and health-related quality of life focused on fatigue, depression and anxiety, and work productivity.

The purpose of this study is to see if whole blood-based blood biomarker (i.e., cytokine) predicts status and severity of diseases such as asthma, Juvenile Idiopathic Arthritis (JIA), Rheumatoid Arthritis (RA), or Inflammatory Bowel Disease (IBD).
