Official title
Visceral Sensitivity in IBD and IBS: Role of Inflammation, Immune Activity and Genetic Factors
Overview
Aim: More insight in pathogenesis of IBS and IBD. Samples are collected in context of an European research project.
Detailed description
Methods:
Sample collection in healthy subjects, IBD and IBS patients:
* biopsy of rectum and colon descendens * blood sample collection * collection of sample of nasal mucosa * feces collection * questionnaires * rectal barostat sensitivity measurement * transit measurement of colon * MR scan of brain
Interventions
- Other Sample collection
Collection of blood, feces samples, sample of nasal mucosa and biopsies (rectum and colon descendens), questionnaires and performance of rectal sensitivity measurement (barostat), MR scan of brain and transit measurement of colon
Primary outcome measures
- differences in visceral sensitivity in different study groups (Visceral sensitivity will me measured by performing a rectal barostat test) [Time frame: at time of investigation (rectal barostat test), Day 1]
Secondary outcome measures (1)
- immune activity (measuring release of mest cell mediators in rectal biopsies, measuring parameters of immune activity in blood) [Time frame: at time of investigation (rectal biopsy), Day 1]
