Background/AimsFor decades, thiopurines have been the mainstay of inflammatory bowel disease (IBD) treatment and will play an important role in the future. However, complex metabolism and various side effects limit the use of these potent drugs in clinical practice. The Korean Association for the Study of Intestinal Diseases developed a set of consensus statements with the aim of guiding clinicians on the appropriate use of thiopurines in the management of IBD.MethodsSixteen statements were initially drafted by five committee members. The quality of evidence and classification of recommendation were assessed according to the Grading of Recommendations Assessment, Development and Evaluation system. The statements were then circulated to IBD experts in Korea for review, feedback, and then finalized and accepted by voting at the consensus meeting.ResultsThe consensus statements comprised four parts: (1) pre-treatment evaluation and management strategy, including value of thiopurine S-methyltransferase screening, dosing schedule, and novel biomarkers for predicting thiopurine-induced leukopenia; (2) treatment with thiopurines with regards to optimal duration of thiopurine treatment and long-term outcomes of combination therapy with anti-tumor necrosis factors; (3) safety of thiopurines, especially during pregnancy and lactation; and (4) monitoring side effects or efficacy of therapy using biomarkers.ConclusionsThiopurines are an effective treatment option for patients with IBD. Management decisions should be individualized according to the risk of relapse and adverse events.
Infliximab was a well-tolerated and effective therapy for patients with moderate-to-severe intestinal BD. Moreover, we found 5 predictive factors associated with sustained response, which might assist in optimal patient selection for infliximab treatment.

Background: Data relating to the association between inflammatory bowel disease (IBD) and pregnancy outcomes are lacking in Korea.
Aims:To determine the incidence rates of pregnancy outcomes in women with IBD.Methods: A nationwide population study was performed using the Korean National Health Insurance claims database. A total of 2058 women with IBD consisting of ulcerative colitis (UC, n = 1469) and Crohn's disease (CD, n = 589) were pregnant between 2007 and 2016. We compared their incidence of pregnancy outcomes with 20 580 age-matched controls without IBD. We also stratified the patients into those with quiescent to mild and moderate to severe IBD and compared the outcomes between them.
Results:The pregnancy rate of women with IBD was lower than that of women without (25.7% vs 32.3%, P < 0.001). Caesarean section (46.5% vs 38.8%, odds ratio [OR]1.43, 95% confidence interval [CI]: 1.17-1.75), and intrauterine growth retardation (IUGR) (3.0% vs 1.0%, OR 2.89, 95% CI: 1.59-5.26) were increased in CD patients than the controls. In regards to disease severity, there were no significant differences in pregnancy outcomes between patients with quiescent to mild IBD and the controls. However, the live birth rate of patients with moderate to severe IBD was lower than that of the controls (65.0% vs 69.9%, OR 0.79, 95%CI: 0.66-0.94). In addition, moderate to severe IBD was significantly associated with spontaneous abortion (14.9% vs 11.9%, OR 1.33, 95% CI: 1.04-1.68), caesarean section (46.4% vs 38.8%, OR 1.41, 95% CI: 1.14-1.74) and IUGR (3.4% vs 1.0%, OR 3.20, 95% CI: 1.75-5.84).
Conclusions:With the exception of moderate to severe disease, the incidences of adverse pregnancy outcomes in women with IBD are similar to that of the general population.
In Korean patients with CD, stricturing, penetrating disease behavior, and smoking habits at the time of diagnosis are independent predictors for CD-related surgery. It was also identified that younger age (< 40 years), ileal involvement, and perianal disease at diagnosis are predictive of a need for immunosuppressive or biological agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
