- Active disease on IUS during pregnancy was associated with 4-fold increased risk of prematurity and 2-fold increased risk of low birth weight, even after adjusting for clinical activity and fecal calprotectin. A bowel wall thickness over 6mm in the second trimester was the strongest predictor of adverse outcomes.
- Agreement between clinical scores and objective markers was minimal to weak throughout pregnancy.
- IUS and FCP are complementary. Using both tools together provides the most accurate disease activity assessment during pregnancy.
- Women in objective remission in the first trimester had an 85.5% chance of maintaining remission in the second trimester. Those with active disease on IUS or elevated FCP in early pregnancy had 4-fold increased risk of disease activity later in pregnancy.
- Active disease on IUS was associated with adverse outcomes including gestational diabetes and preeclampsia, independent of clinical and biochemical markers.
