- Brief Summary
Anti-TNF (tumor necrosing factor) treatment with infliximab (IFX) and adalimumab (ADA) are established first-line biological therapies used in treatment of patients with ulcerative colitis (UC). There are no head-to-head comparative studies between these two drug but meta-analysis of randomized controlled trials states that IFX might be more effective than ADA for the induction of clinical remission. However, several observational studies conclude that ADA seem to have similar effect as IFX in treating patients with UC but these studies have limitations.
The overall aim of this retrospective multicenter observational cohort study is to evaluate if there is a difference in efficacy between infliximab (IFX) and adalimumab (ADA) in treating bio-naive patients with UC in the short and long term during the modern era when therapeutic drug monitoring have been used to optimize anti-TNF treatment.

- Primary Outcome Measures
Name Time Method Percentage of patients achieving steroid-free clinical remission One year after start of anti-TNF therapy Partial Mayo score ≤2 with no subscore \>1 and no use of steroids between 6 and 12 months after start of anti-TNF therapy (Partial Mayoscore, range 0-9, with higher value indicating more severe disease activity).
- Secondary Outcome Measures
Name Time Method Percentage of patients achieving biochemical remission One year after start of anti-TNF therapy Fecal Calprotectin \<250 mg/kg
Percentage of patients achieving clinical response Three months after start of anti-TNF therapy A decrease in the partial Mayo score from baseline of 2 or more points, along with either a rectal bleeding subscore of 0 or 1 or a decrease in the rectal bleeding subscore of 1 point or more (Partial Mayoscore, range 0-9, with higher value indicating more severe disease activity).
Percentage of patients achieving endoscopic response 3-12 months after start of anti-TNF therapy A decrease in endoscopic Mayo score of 1 or more points (Endoscopic Mayoscore, range 0-3, with higher value indicating more severe disease activity).
Percentage of patients achieving clinical remission One year after start of anti-TNF therapy Partial Mayo score ≤2 with no subscore \>1 (Partial Mayoscore, range 0-9, with higher value indicating more severe disease activity).
Percentage of patients achieving endoscopic remission 3-12 months after start of anti-TNF therapy Endoscopic Mayo score 0-1 (Endoscopic Mayoscore, range 0-3, with higher value indicating more severe disease activity).
