The Comparison Between the Biomarkers in Inflammatory Bowel Disease Patients and General Control Group

Conditions
Inflammatory Bowel Diseases
Irritable Bowel Syndrome
Interventions
Other: inflammatory bowel disease
Other: IBS or Normal Control
Registration Number
NCT03778918
Lead Sponsor
Bo-In Lee
Brief Summary

The aims of this study is to investigate a blood-based biomarker that can replace endoscopy in patients with inflammatory bowel disease. For this purpose, blood sample of patients wiht inflammatory bowel disease (ulcerative colitis, Crohn 's disease) was collected at the same time the endoscopy is performed, stored after centrifugation, and analyzed accordingly. Selected biomarkers from the blood sample were investigated to compare those of patients with inflammatory bowel disease and those of general controls. Males and females over the age of 19 participated in the study and are excluded if they have chronic kidney disease or blood clotting disease. The outcome is a find of a blood-based biomarker that best reflects a disease activity.

Detailed Description

Inflammatory bowel disease refers to chronic inflammation of the unknown origin that occurs in the intestine. It usually refers to ulcerative colitis and Crohn's disease, which are idiopathic inflammatory bowel diseases. While it had been known to be a common disease in the western world, in recent decades the incidence of ulcerative colitis and Crohn's disease has rapidly increased in Korea as well. Endoscopic examination is a gold standard in order to determine the activity of inflammatory bowel disease, but it is hardly performed due to the cost and time of a test. Therefore, it is necessary to find a blood-based biomarker that replaces endoscopy. The objective of the study is to identify a new inflammatory marker that replaces endoscopy by comparing blood samples of patients with inflammatory bowel disease with those of general controls.
