Brief Summary:
The researchers will investigate gut microbiome in Korean patients with ulcerative colitis and normal control subjects using metagenomic analysis to elucidate the significant difference between two groups This study will help to understand the association between gut microbiome and inflammatory bowel disease.

Group/Cohort Intervention/treatment
UC group
clinically and microscopically confirmed UC patients between the age of 19 and 75 years
 Procedure: colonoscopy biopsy
colonoscopy biopsy will be conducted in rectum, ascending and descending colon from participants 2 times during study - at active phase and inactive phase

Other: stool collection
stool will be collected from participants 2 times during study - at active phase and inactive phase
Control group
normal healthy controls
 Procedure: Colonoscopy biopsy
Colonoscopy biopsy will be performed in rectum, ascending and descending colon at study entry

Other: stool collection
Stool will be collected from participants at study entry


Outcome Measures
Go to

Primary Outcome Measures :
  1. characterize the difference in gut microbiomes through metagenomic analysis between UC patients and normal control subjects [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. characterize the difference in gut microbiomes through metagenomic analysis between stool specimens and biopsy specimens in participants with UC and normal subjects [ Time Frame: 1 year ]
  2. characterize the difference in gut microbiomes among colonoscopy biopsy locations (rectum, ascending and descending colon) [ Time Frame: 1 year ]
  3. characterize the difference in gut microbiomes between active and inactive UC patients [ Time Frame: 1 year ]

Biospecimen Retention:   Samples With DNA
Participants will need to give stool samples and colorectal biopsy specimens on 1 or 2 separate occasions
