Chronic inflammation can induce leukemogenic mutations in hematopoietic stem cells (HSCs). We report a case of acute promyelocytic leukemia (APL) in a patient with chronic continuous type of Crohn's disease. The patient had been diagnosed with Crohn's disease at the age of 28 years and had received conventional treatments with biologics, but not azathioprine. At the age of 51, he was diagnosed with APL with ider(17). Long-term exposure to chronic continuous inflammation from Crohn's disease might be a factor inducing genomic instability in HSCs, which lead to the subsequent development of APL. APL is a rare hematological manifestation that required attention in Crohn's disease patients.

Background/objectives: Janus kinase inhibitors open new horizons for small-molecule drugs in treating inflammatory bowel disease, with ritlecitinib demonstrating significant efficacy in clinical trials for ulcerative colitis and Crohn's disease. Ritlecitinib, a second-generation JAK3 inhibitor, is a novel therapeutic agent for alopecia areata and other autoimmune conditions.
Methods: A new stability-indicating UHPLC-DAD-MS/MS method was developed, validated, and applied for a forced degradation study of ritlecitinib under ICH guidelines.

The introduction of anti-tumor necrosis factor-α (anti-TNF-α) agents, particularly infliximab (IFX) and adalimumab (ADA), has significantly expanded the therapeutic arsenal for inflammatory bowel disease (IBD). While these biologics have demonstrated substantial efficacy, they are associated with a spectrum of potential adverse events (AEs). This study aims to evaluate and document these AEs to facilitate optimal patient selection and monitoring strategies of patients undergoing these therapies.

Inflammatory bowel diseases (IBD) including Crohn's disease (CD) and ulcerative colitis (UC) are chronic, relapsing conditions characterized by dysregulated immune responses and persistent intestinal inflammation. This review aims to examine new potential therapeutic targets in IBD starting from the STRIDE-II statements. Key targets now include clinical remission, endoscopic remission, and biomarker normalization (such as C-reactive protein and fecal calprotectin).

Unlabelled: Crohn's disease (CD) is a multifactorial inflammatory bowel disease whose pathogenetic mechanisms are a field of ongoing study. Changes in the intestinal microbiome in CD may influence metabolite production and reflect the disease's severity. We investigate the relationship between trimethylamine N-oxide (TMAO) and lipopolysaccharide-binding protein (LPS) levels and changes in the gut microbiome in patients with CD of various degrees of activity.

Despite the increasing number of available medications, a significant proportion of IBD patients fail to achieve the current therapeutic targets. Uncontrolled IBD has a significant impact on patients' quality of life and on overall costs for the healthcare system. Given the complex pathophysiology of IBD, Combined Advanced Targeted Therapy (CATT), involving the combination of biologics/small molecules, appears to have biological plausibility and is gaining increasing interest.
