Uitkomstmaten
Primaire uitkomstmaten
- Gut microbiome changes over the course of pregnancy (before pregnancy, T1, T2 and T3 after delivery and and at least 3 months after delivery) in terms of diversity, taxonomic changes and richness
- Gut microbiome changes in children from IBD mothers in terms of diversity, taxonomic changes and richness compared to a historical cohort
- Disease activity during pregnancy as measured by clinical activity scores (Harvey Bradshaw Index for CD and Simplified Clinical Colitis Activity Index), laboratory findings and/or endoscopy findings.
Achtergrond van het onderzoek
Prospective follow up of the natural history of pregnant IBD patients. In order to provide patients with appropriate pre-conceptional counseling regarding their disease in combination with pregnancy, more research needs to be done on this subject. We therefore aim to describe the natural history of IBD during and after pregnancy, investigate the gut microbiome at several time points during and after pregnancy and eventually assess the health and microbiome of the children born to IBD mothers in comparison to children of healthy mothers.
Doel van het onderzoek
Studies have described an altered bacterial diversity in the gut of women with IBD as compared to healthy controls. Infants born to mothers with IBD have shown to have lower diversity and altered gut microbiome at least until age 3 months. This might be important since prenatal and early life microbiome is thought to influence the development of the immune system. Whether this altered gut microbiome remains in women after pregnancy and in infants beyond age 3 months is unclear. We will perform follow up on the gut microbiome of women who previously in the study participated and their children beyond 3 months of age.
