scores, duration, site and concomitant medications were recorded. Pregnancy outcomes including mode of delivery, miscarriage, ante/postnatal complications, age at conception and need for escalation of IBD treatment during pregnancy were also assessed. Neonatal outcomes including low birth weight, pre-term delivery, NICU stays or perinatal infection and timing of vaccines were also recorded. Data were analysed using t testing, contingency and logistic regression analyses. Results: From an IBD population of over 2,500 patients, 31 individual females who underwent anti-TNF treatment during pregnancy from 2008 2013 were identified with a total of 36 pregnancies. Median disease duration at time of pregnancy was 12 years (IQR 3 17). 85% had Crohn’s Disease, 15% Ulcerative Colitis. Median Harvey Bradshaw Index pre-pregnancy was 4.5 (IQR 2 13). Median Mayo score was 1 (IQR 0 3). 57.3% received infliximab, 38% adalimumab, 4.7% certolizimab. 53.8% were on concomitant immunemodulators. The majority of patients stopped biologic treatment at the start of the third trimester. 67% had treatment reinstated in the postpartum period. Median age at conception was 30.5 (IQR 25 35). 19% had previous miscarriages. 92% had successful term pregnancies. 22% required escalation of treatment during pregnancy. 19.3% had a pregnancy complication including emergency section. 16% neonates had a low birth weight with 2 preterm deliveries and one case of NICU stay for meconium ileus. No perinatal infections were reported. 20% mothers breastfed. The majority of mothers delayed live vaccination of their children. Interestingly, there was a significant independent association between disease activity at time of conception and low birthweight (p < 0.01). There was no association between adverse outcomes or neonatal infections and anti-TNF use noted in this cohort. Conclusions: Disease control at time of conception and through pregnancy should be the main goal of treatment in this patient cohort and the use of TNF alpha antagonists to achieve this appears to warranted to improve pregnancy outcomes though definitive safety has yet to be proven. |
