Purpose

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.

Further study details as provided by Seoul National University Hospital:

Primary Outcome Measures:

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

Secondary Outcome Measures:

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 ]
characterize the difference in gut microbiomes among colonoscopy biopsy locations (rectum, ascending and descending colon) [ Time Frame: 1 year ]
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
