Summary: In patients with ulcerative colitis, the study found that 200 mg of filgotinib can reduce the use of corticosteroids and maintain corticosteroid-free clinical remission. Moreover, compared to other medications, filgotinib demonstrated better outcomes in patients who had not previously used biologic agents.

Summary: Analyzing and classifying ulcerative colitis (UC) clinically is beneficial for the study of pathogenesis, disease monitoring, and precise treatment. The differential clinical indicators associated with the extent of colon lesions can serve as potential markers for predicting disease progression and prognosis, and have significant implications for UC mechanism research and drug development. Biomarkers can be selected based on the site of the lesion.

Summary: This study examined the association between fecal microbial composition and response to systemic corticosteroids in patients with active ulcerative colitis. It found that baseline microbial diversity and composition could not predict response to corticosteroids, but responders had significant changes in microbial diversity and composition after 4 weeks of treatment.

Summary: This multicenter study found low agreement among pediatric endoscopists in evaluating endoscopic scores in children with IBD, particularly in UC. By using disease activity categorization, agreement slightly increased, mainly for CD. All readers showed low-grade concordance with the expert evaluations, suggesting the need for future training programs to improve IOA in using IBD endoscopic activity scores.

Summary: This study compared total abdominal colectomy (TAC) with ileostomy and partial colectomy (PC) with colostomy as treatment options for severe ulcerative colitis (UC). The results showed that PC had similar 30-day outcomes to TAC and may be an acceptable alternative in selected patients.

Summary: The effectiveness of corticosteroids in ulcerative colitis patients needs to be reevaluated. This study found that 73% of patients achieved clinical response after 4 weeks, and 68% achieved combined response. Disease activity did not affect short-term treatment response but increased the risk of steroid dependence. Biologic-naive patients responded better than biologic-experienced patients.

Summary: In this randomized controlled trial, the combination of mesalamine with corticosteroids did not show superior efficacy compared to corticosteroids alone in hospitalized patients with acute severe ulcerative colitis (ASUC). However, there was a potential indication that the need for biologics was reduced in the mesalamine group within 90 days.

Summary: By surveying experts and conducting systematic reviews, key predictors for pediatric UC outcomes, including colectomy, acute severe colitis, and cancer, were identified. These predictions can be used for personalized treatment approaches, improving outcomes for pediatric UC patients.

Summary: The incidence of pediatric-onset inflammatory bowel disease (IBD) is increasing worldwide, with the highest rates in Northern Europe and North America and the lowest rates in Southern Europe, Asia, and the Middle East. Most studies reported significant increases in incidence, while there is limited data on very early onset IBD.

Summary: Central reading is advocated for clinical trials in ulcerative colitis, but it is uncertain whether the local/site reader should be included. This study found that using locally- and centrally-determined endoscopic Mayo subscores can provide a reliable final assessment, and the reading paradigm used has an impact on effect size.

Summary: This study evaluated the effectiveness of corticosteroids in immunosuppressed patients with inflammatory bowel disease (IBD) and found that 23% of patients needed at least one course of steroids, with CD patients more likely to escalate to biologics or surgery. Patients with CD displaying fibrostenotic (B2) and fistulizing (B3) behaviors were at a higher risk for requiring steroids after immunosuppressive treatment.

Summary: Advances in diagnostics and treatment strategies for inflammatory bowel diseases have led to the establishment of new therapeutic goals. Achieving endoscopic remission is desired, but a significant proportion of patients in remission still show microscopic disease activity. Histological evaluation has shown better predictive value for clinical complications, but validated scoring indices are currently lacking.

Summary: This study aims to validate the correlation between red dichromatic imaging (RDI) scores and the activity index of ulcerative colitis (UC). The results showed positive correlations between RDI scores and UCEIS, MES, and Nancy index. RDI scores had a higher correlation to histology compared to white-light imaging (WLI) scores.

Summary: The incidence of very early onset inflammatory bowel disease (VEOIBD) is increasing, with predominantly colonic involvement and infrequent stricturing/penetrating disease. The risk of bowel surgery in Crohn's disease patients was approximately 15% by 5 years, while in ulcerative colitis patients it was 14%.

Summary: This study identified an ileal gene program for macrophage and fibroblast activation linked to stricturing complications in treatment of naïve pediatric CD. The research may inform novel small molecule therapeutic approaches targeting macrophage and fibroblast activation and angiogenesis to reverse the stricturing gene signature.

Summary: This study developed a model for predicting the risk of colectomy in children newly diagnosed with ulcerative colitis. The findings suggest that a small group of children with severe UC still require colectomy despite current therapies. The gene signature observations provide additional targets for managing patients who do not respond to current medical treatments.

Summary: Research demonstrates that gene expression profiling can accurately predict the risk of colectomy in ulcerative colitis (UC) patients. Single-cell analysis reveals the activity of genes in diverse cell types. Furthermore, summarizing the effects of transcriptome-wide association studies can also accurately predict the risk of colectomy in UC patients.

Summary: Food additives, especially emulsifiers, are considered important components of the diet that may potentially harm the intestine. However, there is insufficient objective information about the specific nature and extent of this problem. The FDA has recognized certain substances as generally safe and approved numerous food additives, but the criteria for these selections lack transparency. Once designated as food additives or included on the GRAS list, there is no regulatory mechanism for ongoing safety monitoring. The aim of this introduction to emulsifiers is to raise awareness about the current state of food additives in the USA and promote careful study of all additives in our diets, with the ultimate goal of ensuring food safety.

Summary: This article describes the utilization and durability of anti-TNF therapy in children with very early onset inflammatory bowel disease (VEOIBD). The study found that the utilization and durability of anti-TNF therapy in VEOIBD children is relatively high and comparable with older children. Having Crohn disease is associated with greater durability compared to UC/IBD-U.

Summary: This study aimed to predict clinical outcomes in pediatric ulcerative colitis (UC) through assessing gene expression and investigate the potential pathogenic roles of predictive genes. IL13RA2 was associated with corticosteroid-free remission, while RORC was associated with a lower likelihood of colectomy. RNA sequencing and immunostaining supported these findings.
