Abstract 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 (Grading of Recommendations Assessment, Development, and Evaluation) process was used when sufficient published data were available and the RAND (Research and Development) 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.

Abstract During the 20th century, inflammatory bowel disease (IBD) was considered a disease of early-industrialized regions in North America, Europe, and Oceania. At the turn of the 21st century, incidence of IBD increased in newly-industrialized and emerging regions in Africa, Asia, and Latin America, while prevalence in early-industrialized regions started to grow steadily. Changes in incidence and prevalence denote evolution of IBD across four epidemiologic stages: Stage 1 (Emergence), characterized by low incidence and prevalence; stage 2 (Acceleration in Incidence), characterized by rapidly rising incidence and low prevalence; and stage 3 (Compounding Prevalence), characterized by decelerating, plateauing, or declining incidence and steadily rising prevalence. A fourth stage (Prevalence Equilibrium) has been proposed where the slope of prevalence plateaus due to shifting demographics of an aging IBD population, but it has not yet been evidenced. To date, these stages have been theoretical without specific incidence/prevalence indicators defining transition points. Using real-world data from 490 population-based studies comprising 80 global regions and spanning over a century (1920–2023), we show spatiotemporal transitions across stages 1–3 and model transition towards stage 4. Understanding the evolution of IBD across epidemiologic stages allows healthcare systems to better prepare for the future worldwide burden of IBD.

Abstract Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety of tofacitinib were demonstrated in patients with moderate to severe UC in 3 Phase 3 studies.1 Here, we present data from an ongoing, open-label, long-term extension (OLE) study.2 Methods We present updated safety and efficacy data from the OLE study (OCTAVE Open, NCT01470612; as of May 2019, database not locked). Eligible patients included non-responders (Week 8 data) in OCTAVE Induction 1 and 2 (NCT01465763; NCT01458951) and completers (Week 52 data) or treatment failures (early-termination data) in OCTAVE Sustain (NCT01458574). Patients in remission (total Mayo score ≤2, no individual subscore >1, rectal bleeding [RB] subscore 0) at Week 52 of OCTAVE Sustain (central read) received tofacitinib 5 mg twice daily (BID); all others received 10 mg BID. Induction non-responders without clinical response (≥3-point and ≥30% decrease from induction study baseline total Mayo score, plus ≥1-point RB subscore decrease or absolute RB subscore ≤1) at Month 2 of the OLE study were withdrawn. Incidence rates (IRs) for adverse events (AEs) of special interest were calculated (no. of unique patients with events per 100 patient-years). Efficacy endpoints were derived from Mayo score (local read) with non-responder and last observation carried forward imputation (NRI-LOCF) [a]. Results Of 944 patients who received ≥1 dose of tofacitinib, 769 (81.5%) received 10 mg BID (median duration [range]: 5 mg BID 1170 [36–2066]; 10 mg BID 668 [1–2159] days). In total, 338 (35.8%) and 93 (9.9%) patients discontinued due to insufficient clinical response and AEs (excl. worsening UC), respectively. IRs (95% confidence interval) in the Tofacitinib. All group were: deaths 0.18 (0.05, 0.47); serious infections 1.57 (1.08, 2.19); herpes zoster (non-serious and serious) 3.27 (2.54, 4.14); major adverse cardiovascular events 0.14 (0.03, 0.40); malignancies excl. non-melanoma skin cancer (NMSC) 0.92 (0.56, 1.42); NMSC 0.74 (0.43, 1.21); deep vein thrombosis 0.05 (0.00, 0.25); pulmonary embolism 0.18 (0.05, 0.47) (Table). At Month 36 (NRI-LOCF), 58.9% (n = 103) and 33.5% (n = 257) were in remission, 64.6% (n = 113) and 37.0% (n = 284) had mucosal healing (Mayo endoscopic subscore of 0 or 1) [b] and 66.9% (n = 117) and 40.2% (n = 309) showed clinical response, in the 5 and 10 mg BID groups, respectively. Conclusion Incidence of AEs remained generally consistent in patients with moderate to severe UC in the OLE study compared with a previous analysis.2 Data continue to support long-term efficacy with tofacitinib up to 36 months beyond Week 52 of OCTAVE Sustain.
