Background & aims Pregnancy can be a complex and risk filled event for women with inflammatory bowel disease (IBD). High-quality studies in this population are lacking, with limited data on medications approved to treat IBD during pregnancy. For patients, limited knowledge surrounding pregnancy impacts pregnancy rates, medication adherence, and outcomes. Limited provider knowledge leads to highly varied practices in care affected by local dogma, available resources, individual interpretation of the literature, and fear of harming the fetus. The variations in guidelines by different societies and countries reflect this and lead to confusion for physicians and patients alike. The Global Consensus Consortium is a group of 39 IBD and content experts and 7 patient advocates from 6 continents who convened to review and assess current data and come to an agreement on best practices based on these data. Methods The GRADE process was used when sufficient published data were available and the RAND process in those instances where expert opinion was needed to guide consistent practice. Recommendations were informed by the guiding principle that maternal health best supports infant health. Results The topics were divided into ten categories with 34 GRADE recommendations and 35 Consensus statements. Conclusions Overall, the goal of the group was to provide data-driven and practical guidance to improve the care of women with IBD around the globe based on the best available research.

AbstractBackgroundPYRAMID was an international post‐marketing registry that aimed to collect data on the long‐term safety and effectiveness of adalimumab treatment per local standard of care in patients with moderately to severely active Crohn's disease (CD). Here, we present post hoc analyses of observational data from patients who became pregnant while participating in this registry and receiving adalimumab.MethodsFrom the subpopulation of patients receiving adalimumab who became pregnant while taking part in PYRAMID, data on patient characteristics, pregnancy outcomes, and complications of pregnancy were analysed retrospectively.ResultsAcross the PYRAMID registry, 293 pregnancies occurred in patients who had gestational adalimumab exposure (average disease duration at last menstrual period: 8.6 years), resulting in 300 pregnancy outcomes. A total of 197 pregnancies (67.2%) were exposed to adalimumab in all trimesters per physician's decision. Of the known reported outcomes (96.3%), 81.7% (236/289) were live births, 10.4% (30/289) were spontaneous abortions, 4.8% (14/289) elective terminations, 2.8% (8/289) ectopic pregnancies, and 0.3% (1/289) was a stillbirth. Congenital malformations (pulmonary valve stenosis and tricuspid valve incompetence) were reported in one infant. In addition to the pregnancy outcomes described above, 23 complications of pregnancy were reported in 20 patients.ConclusionsThis analysis showed that adalimumab treatment in patients with CD, who became pregnant whilst participating in the PYRAMID registry, contributed no additional adverse effects during the pregnancy course or on pregnancy outcomes.

Abstract Background & Aims Crohn’s disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. Methods We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a group of specialists. Results The consensus includes 41 statements focused on 6 main drug classes: antibiotics, 5-aminosalicylate, corticosteroids, immunosuppressants, biologic therapies, and other therapies. The group suggested against the use of antibiotics or 5-aminosalicylate as induction or maintenance therapies. Corticosteroid therapies (including budesonide) can be used as induction, but not maintenance therapies. Among immunosuppressants, thiopurines should not be used for induction, but can be used for maintenance therapy for selected low-risk patients. Parenteral methotrexate was proposed for induction and maintenance therapy in patients with corticosteroid-dependent CD. Biologic agents, including tumor necrosis factor antagonists, vedolizumab, and ustekinumab, were recommended for patients failed by conventional induction therapies and as maintenance therapy. The consensus group was unable to clearly define the role of concomitant immunosuppressant therapies in initiation of treatment with a biologic agent. Conclusions Optimal management of CD requires careful patient assessment, acknowledgement of patient preferences, evidence-based use of existing therapies, and thorough assessment to define treatment success.
