Safety of in utero exposure to maternal IBD pharmacotherapies

Although available clinical outcome data are reassuring, the consequences of in utero exposure to inflammatory bowel disease (IBD) pharmacotherapies on the development of the neonatal immune system remain ill-defined. So too does the converse effect on immunological maturation of fetal exposure to maternal inflammatory activity. Both warrant elucidation to appropriately stratify antenatal IBD care.
