Injectable DAT-ALG Hydrogel Mitigates Senescence of Loaded DPMSCs and Boosts Healing of Perianal Fistulas in Crohn's Disease.
ACS Biomater Sci Eng

Perianal fistulas (PAFs) are a severe complication of Crohn's disease that significantly impact patient prognosis and quality of life. While stem-cell-based strategies have been widely applied for PAF treatment, their efficacy remains limited. Our study introduces an injectable, temperature-controlled decellularized adipose tissue-alginate hydrogel loaded with dental pulp mesenchymal stem cells (DPMSCs) for in vivo fistula treatment.

Background And Aims: Nationwide, population-based studies of chronic non-bacterial osteomyelitis (CNO) in patients with childhood-onset inflammatory bowel disease (IBD) are lacking.
Methods: We used nationwide registers to identify all children in Sweden diagnosed with IBD during 2002-2022 and the occurrence of CNO in this IBD cohort and general population non-IBD comparators. To estimate the temporal associations between IBD and CNO we used Cox regression.
Improvement in Serum Eosinophilia is Observed in Clinical Responders to Ustekinumab but not Adalimumab in Inflammatory Bowel Disease.

Introduction: In inflammatory bowel disease (IBD), the number of eosinophils increases in the lamina propria of the intestinal tract, but their specific patho-mechanistic role remains unclear. Elevated blood eosinophil counts in active IBD suggest their potential as biomarkers for predicting response to biologic therapies. This study evaluates blood eosinophil count trends and their predictive value for clinical response and endoscopic improvement in patients with IBD receiving ustekinumab or adalimumab induction therapy.

Inflammatory bowel disease (IBD) is a protracted, persistent gastrointestinal disease that is distinguished by recurring, persistent inflammation of the digestive tract. IBD, including Crohn's disease and ulcerative colitis, is characterized by persistent inflammation due to immune dysregulation. Interleukin -17 (IL-17) contributes significantly to the pathophysiology of IBD, as highlighted in the context of the provided research.

We use a TNF-overexpressing Crohn's disease (CD) model (Tnf ), which typically presents in the terminal ileum (TI), to investigate how environmental factors interact with the host's immune susceptibility to drive region-specific disease. We identified , an intracellular bacterium and murine counterpart to the human sexually transmitted , as necessary and sufficient to trigger disease manifestation in the ascending colon (AC), another common site of human CD.
