self-questionnaires: Patients will fill in these self-questionnaires on a tablet or on paper, depending on the availability of tablets in the centres, before and after consulting the doctor. These questionnaires assess the severity of the disease and quality of life.
unique collection of saddles: Stool samples will be taken at each visit, i.e. approximately every 6 months for patients

The first part contains questions known as the 'EQ-5D descriptive system', supplemented by a visual analogue scale known as the 'EQ-5D VAS'. It consists of a 20 cm, graduated from 0 to 100, on which the patient is asked to indicate how they rate their current state of health, with 0 being the worst possible state and 100 being the best. and 100 being the best.).
Clinical prognostic factors for the disease (medical interview) — Visit V0 (inclusion) Assessment of sexual or physical aggression (medical interview), post-infectious nature (medical interview)

Evaluation of validated questionnaires (VSI Score) — Visit V0 (inclusion), Visits at 6 , 12, 18, 24, 30 and 36 months A standardized psychological questionnaire that assesses coping strategies, that is, how a person deals with stress. 15 items describe a possible reaction to stress. For each of the 15 items, the person indicates to what extent the described reaction corresponds to them when they are stressed (in the face of pain, constipation, bloating, or an urgent need to go to the toilet). Six rating scales are used, ranging from: 1 strongly agree, 2 somewhat agree, 3 slightly agree, 4 slightly disagree, 5 somewhat disagree, and 6 strongly disagree

Evaluation of validated questionnaires (CISS) — Visit V0 (inclusion), Visits at 6 , 12, 18, 24, 30 and 36 months This assessment evaluates an individual's cognitive and behavioral efforts to manage a situation perceived as stressful. Seven items, each worth 5 points, assess a single coping style (minimum score of 7 and maximum of 28).
