The purpose of this study is to describe clinical course of newly diagnosed moderate to severe ulcerative colitis (chronic inflammatory disease of the colon) in tertiary referral hospitals in Korea for 5-year follow-up under usual care.
This is a multicenter (when medical research study takes place in more than one country), prospective (study following participants forward in time), disease-oriented and hospital-based 5-year follow-up longitudinal study in Korean participants with newly diagnosed moderate to severe ulcerative colitis who visit tertiary referral hospital. As the study is observational in nature, no intervention will be received by participants. Efficacy will primarily be assessed by number of relapses and percentage of participants achieving sustained remission (clinical, endoscopic and combined remission).

Total Number of Relapses in Year 1
Relapse is defined as increase in Mayo or partial Mayo score of more than or equal to (\>=) 3 points from clinical response or remission. Mayo score is a discrete ordinal scale with total score ranging from 0 (normal or inactive disease) to 12 (severe disease) and partial Mayo score ranges from 0 (normal or inactive disease) to 9 (severe disease). Relapses will be categorized as: infrequent (less than or equal to \[\<=\] 1 relapse per year), frequent pattern (\>=2 relapses per year) and continuous (persistent symptoms of active ulcerative colitis without a period of remission).
Time frame: Year 1
Total Number of Relapses in Year 3
Relapse is defined as increase in Mayo or partial Mayo score of \>=3 points from clinical response or remission. Mayo score is a discrete ordinal scale with total score ranging from 0 (normal or inactive disease) to 12 (severe disease) and partial Mayo score ranges from 0 (normal or inactive disease) to 9 (severe disease). Relapses will be categorized as: infrequent (\<=1 relapse per year), frequent pattern (\>=2 relapses per year) and continuous (persistent symptoms of active ulcerative colitis without a period of remission).
Time frame: Year 3
Total Number of Relapses in Year 5
Relapse is defined as increase in Mayo or partial Mayo score of \>=3 points from clinical response or remission. Mayo score is a discrete ordinal scale with total score ranging from 0 (normal or inactive disease) to 12 (severe disease) and partial Mayo score ranges from 0 (normal or inactive disease) to 9 (severe disease). Relapses will be categorized as: infrequent (\<=1 relapse per year), frequent pattern (\>=2 relapses per year) and continuous (persistent symptoms of active ulcerative colitis without a period of remission).
Time frame: Year 5
Percentage of Participants With Sustained Remission in Year 1
Clinical remission is \<=2 points with no individual sub-score \>1 point using total or partial Mayo Score. Mayo score is a discrete ordinal scale with total score ranging from 0 (normal or inactive disease) to 12 (severe disease) and partial Mayo Score score ranges from 0 (normal or inactive disease) to 9 (severe disease).

Mean Time to Relapse
Relapse is defined as increase in mayo or partial Mayo score of more than or equal to (\>=) 3 points from clinical response or remission. Mayo score is a discrete ordinal scale with total score ranging from 0 (normal or inactive disease) to 12 (severe disease) and partial Mayo score ranges from 0 (normal or inactive disease) to 9 (severe disease). Average time taken to occurrence of first relapse will be observed.
Time frame: Year 1, 3 and 5
Percentage of Participants With Sustained Clinical Response
Response is defined as decrease in Mayo or partial Mayo score of \>=3 points from Baseline and decrease in Mayo score of \>=30 percent (%) from Baseline and decrease in the rectal bleeding score \>=1 or an absolute rectal bleeding score of 0 or 1.

Mean Change From Baseline in Short Form Survey (SF 12) Score at Year 1, 3 and 5
The SF12 is a generic measure physical and mental health, it is is weighted and summed to provide easily interpretable scales. Physical and Mental Health Composite Scores (PCS \& MCS) are computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.
Time frame: Baseline, Year 1, 3 and 5
