Primary | Changes in delta indomethacin challenged permeability at end of intervention period | In vivo multi-sugar permeability test | 6 weeks | |
Secondary | Changes in faecal microbiota composition at end of intervention period | 16S rRNA-based sequencing | 6 weeks | |
Secondary | Changes in cytokine levels at end of intervention period | Multiplex assay for IL-1ß, IL-6, IL-8, IL-10, IL-2, IL-12p70, IFN-? and TNF-a | 6 weeks | |
Secondary | Changes in reactive oxygen species levels at end of intervention period | FORT test for hydrogen peroxide | 6 weeks | |
Secondary | Changes in gastrointestinal symptom questionnaire scores at end of intervention period | The Gastrointestinal Symptoms Rating Scale (GSRS) evaluates gastrointestinal (GI) symptoms based on the 5 domains diarrhoea, constipation, reflux, indigestion and abdominal pain. The symptoms are assessed with 15 items, ranging in scores 1 to 7 depending on their severity. A score of 1 represents "no problems" and score 7 represents "severe problems". The severity of symptoms may be defined as no problems (1 point), mild (1-2 points), moderate (2-4 points), and severe (4-7 points). The scores for each domain was calculated as the mean score of each corresponding item while the mean total GSRS score reflects the general severity of GI symptoms. | 6 weeks | |
Secondary | Changes in hospital and anxiety depression scores at end of intervention period | The Hospital Anxiety and Depression Scale (HADS) was used to evaluate the psychological distress of study participants.This questionnaire consists of 14 items subdivided in two subscales for the assessment of anxiety or depression. The total score is used as a measure of general psychological distress. The minimum score is 0 and the maximum score is 21. A score > 8 on respective subscales indicates a significant level of anxiety or depression. | 6 weeks | |
Secondary | Changes in perceived stress scale scores at end of intervention period | The perceived stress scale (PSS) consists of 10 items, including a number of direct questions about current levels of experienced stress. The respondent answers how often a certain emotion has been present during the past month. PSS scores are obtained by reversing responses (e.g., 0 = 4, 1 = 3, 2 = 2, 3 = 1 & 4 = 0) to the four positively stated items (items 4, 5, 7, & 8) and then summing across all scale items. Each item is rated on a 5-point scale ranging from never (0) to almost always (4). The questions in this scale ask about the responders feelings and thoughts during the last month. In each case the questionnaire requires the respondent to indicate by circling how often they felt or thought a certain way. | 6 weeks | |
Secondary | Changes in quality of life questionnaire scores at end of intervention period | The EuroQol 5D-5L (EQ-5D-5L) tool consists of two parts; 5Q-5D, which includes 5 items related to wellbeing and function (mobility, self-care, usual activities, pain/discomfort and anxiety/ depression) and the visual analogue scale, 5Q-5D-VAS, ranging from 0 to 100. | 6 weeks |
