Inflammatory bowel diseases (IBD) are commonly diagnosed in women of childbearing age. As such, pregnancy is often encountered in this subset of patients. Disease flare throughout gestation are not uncommon and can substantially affect pregnancy outcomes. We aimed at the effect of prior pregnancy outcome on the risk of disease flare at subsequent pregnancy in women with IBD.
Women with IBD attending a multidisciplinary clinic for the preconception, antenatal and postnatal treatment were prospectively recruited during 2011–2018.
Overall, 476 IBD women were followed during the study period. Of them, 69 (14.5%) had two pregnancies throughout the follow-up period and constituted the study cohort. Among these 69 women, 48 (69.6%) had Crohn’s disease and 21 (30.4%) ulcerative colitis. The median interpregnancy interval was 20 [11–32] months. Overall, 34 (49.3%) women experienced disease flare at the subsequent pregnancy. In multivariate analysis, active disease at conception (odds ratio [95% CI]: 25.65 (3.05, 215.52),
History of disease relapse at previous gestation and periconception disease activity were found as an important predictor of disease flare among IBD women. These data would facilitate adequate counselling and informed management decisions among reproductive-aged IBD women and their treating physicians.
