Brief summary
Inflammatory bowel diseases (IBD) represent a group of immune-mediated disorders, in which currently unidentified trigger factors drive the manifestation of chronic relapsing- remitting destructive inflammatory episodes in the gut. IBD comprise two main disease entities, ulcerati\\ie colitis (UC) and Crohn s disease (CD). The diseases differ in anatomical distribution, with continuous, uniform inflammation restricted to the colon in UC, and multifocal inflammation extended throughout the entire gastrointestinal tract from mouth to anus in CD. Clinical symptoms of IBD may include bloody stools, abdominal pain, fatigue, diarrhoea, fever and weight loss. Extra-intestinal symptoms occurring in up to 40% of patients, e.g. anaemia, skin lesions (e.g. erythema nodosum, pyoderma), arthritis and uveitis, and other complications directly related to the disease organ, such as fistula in CD are considered to reflect an overwhelming systemic inflammatory state. Disease onset typically manifests at age 15-35 years, men and women are almost equally affected. In addition, paediatric forms of IBD that often represent complex, se\\/ere monogenic forms of the disease, are seen. The incidence rates of IBD in Europe are about 6.3 (CD) and 11.8 (UC) per 100.000 persons. With growing incidence rates and overall reduced mortality the lifetime prevalence of IBD is expected to rise. The estimated lifetime prevalence of 0.3%-0.5% of the European population corresponds to estimates of 1.5-2 million patients with IBD. Appropriate selection of therapies and their timing of introduction (decision support) in the course of IBD will be essential to reach a higher degree of disease control (across patients and within individual patients) than it is achie\\led today. In many instances, comparati\\ie data is missing and combinations or sequential therapies are not developed. In summary, despite some treatment successes, major challenges remain. The investigators have decided to include patients with inflammatory bowel disease (IBD) in which targeted therapies are administered as part of standard helathcare and which aims at identifiyng solid biomarker signatures as well as molecular pathways and mechanisms linked to response and non-response to therapy. Choice od medications (which are all approved for first line use) is by treating physicians. All follow-up procedures are according to standards of care.
Interventions
OTHERSamples

| To identify solid biomarkers signatures as well as molecular pathways and mechanisms linked to response and non-response to therapy in Crohn's disease patient. | week 14 | -For Crohn's Disease (CD) patient : Crohn's disease activity index (CDAI) and simple endoscopic response (SES-CD) wil be measured. CDAI is the sum of 8 components: number of liquid or soft stools, daily abdominal pain, patient well-being, complications, use of diphenoxylate or opiates as anti-diarreheal, abdominal mass, hematocrit and body weight. Level of disease activity: Non-active disease: CDAI \< 150 Mild disease activity: CDAI \>= 150 and \<220 Moderate disease activity: CDAI \>= 220 and \<450 Severe disease activity: CDAI \> 450 SES-CD assesses the size of mucosal ulcers, the ulcerated surface, the endoscopic extension and the presence of stenosis. SES-CD score: 0 - 2 remission 3 - 6 mild endoscopic activity 7 - 15 moderate endoscopic activity \> 15 severe endoscopic activity |

Mayo score composed by 4 items: stool frequency; rectal bleeding, mucosal appearance at endoscopy and physician rating of disease activity. Mayo score: Score \<2 : no activity Score between 3 and 5: mild activity Score between 6 and 10 :moderate activity Score \>11 : severe activity |

| Measure | Time frame | Description |
|---|---|---|
| General Health Survey assessment | Baseline visit (time -4 weeks to 0), visit 1 (time 0), visit 2 (time 0+2 weeks), visit 3 (time 0+14 weeks), visit 4 (time 0+26 weeks) and visit 5 (time 0+52 weeks) | Evaluated by the The Short Form (36) Health Survey (SF36). SF36 is a patient-reported survey of patient health that covers physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. Score range from 0 to 100. 100= more favorable health state. 0= worst health state. |
| Health status assessment | Baseline visit (time -4 weeks to 0), visit 1 (time 0), visit 2 (time 0+2 weeks), visit 3 (time 0+14 weeks), visit 4 (time 0+26 weeks) and visit 5 (time 0+52 weeks) | Evaluated by the 5-level EQ-5D version (EQ-5D-5L). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Score between 5 and 25. 5=best health state 25= worst health state The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. 100= best health state 0= worst health state. |
| Medical complications | Until week 104 | Long-term outcome (complications until week 104). Complication like stenosis, fistula, development of PSC, infections, flares, hospitalizations, treatment intensification including introduction of toxic long-term therapies (i.e. systemic glucocorticoids) or intestinal surgery will be documented during the entire observational period. |
| Emotional distress-depression assessment | Baseline visit (time -4 weeks to 0), visit 1 (time 0), visit 2 (time 0+2 weeks), visit 3 (time 0+14 weeks), visit 4 (time 0+26 weeks) and visit 5 (time 0+52 weeks) | Evaluated by Patient-Reported Outcomes Measurement Information System® (PROMIS®) Depression scale. PROMIS-Depression is a 8-items scale. Score between 8 and 40. 8= best health statein the past 7 days. 40= worst health state in the past 7 days. |
| Fatigue assessment | Baseline visit (time -4 weeks to 0), visit 1 (time 0), visit 2 (time 0+2 weeks), visit 3 (time 0+14 weeks), visit 4 (time 0+26 weeks) and visit 5 (time 0+52 weeks) | Evaluated by Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). FACIT-F is a 40-items measure that assesses self-reported fatigue and its impact upon daily activites and function. 5 point Likert-type scale. Subscale domains: Physical Well-Being, Social/Family Well-Being, Emotional Well-Being, Functional Well-Being, Fatigue Minimum value: 0 = better outcome Maximum value: 160= worst outcome |
