Official title

Predictors of Response After Induction Therapy With TNF-alpha Inhibitor in Inflammatory Bowel Disease, Comparison to Normal

Overview

A study of clinical characteristics and potential prognostic factors in inflammatory bowel disease

Detailed description

Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory disease composed of two types: Crohn's disease (CD) and ulcerative colitis (UC). It is difficult to cure the IBD completely and patients with clinical or endoscopic remission can worsen again. Therefore, predicting the prognosis of patients with IBD is still challenging.

Endoscopic biopsied samples and blood samples from IBD patients and non-IBD controls have been collected and the expression levels of multiple markers which are associated with disease activity and severity will be assessed. The correlation between expression levels of multiple markers and prognosis will be evaluated.

Interventions

  • Other Endoscopic biopsy
    When patients have colonoscopy or sigmoidoscopy for evaluation of their disease course, biopsied samples are collected. In the IBD group, samples are obtained at endoscopically active and/or inactive lesions. In the control group, samples are obtained at endoscopically normal lesions.

Primary outcome measures

  • The expression level of multiple markers associated with IBD activity or prognosis [Time frame: baseline (at the time of enrollment)]
Secondary outcome measures (1)
  • The change of expression level of multiple markers associated with IBD activity or prognosis [Time frame: Every 2 years. The examination will be suspended when treatment was ended.]

Eligibility criteria

Inclusion criteria

  • control group: Patients who do not have colitis, cancer, and advanced polyp (the number of polyps ≥ 3, the size of polyps ≥ 1cm, high-grade adenoma, villous adenoma)
  • TNF-α inhibitor-naive IBD group: IBD patients who do not have a history of TNF-α inhibitor treatment
  • TNF-α inhibitor-treated IBD group: IBD patients who are treated with TNF-α inhibitor

Exclusion criteria

  • Age under 18 years
  • Patients who were treated with antibiotics or probiotics within the last 3 months

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
