Investigation of the Correlation Between Polyamine Levels and Their Key Enzymatic Activities in Association With Inflammatory Bowel Disease Progression

Inflammatory Bowel Disease (IBD), encompassing Ulcerative Colitis (UC) and Crohn's Disease (CD), significantly impairs patients' quality of life. Current monitoring of disease activity primarily relies on endoscopy combined with histological examination, which is associated with high costs, invasiveness, poor patient tolerance, and risks of complications. Additionally, disease activity indices and laboratory-based IBD staging metrics demonstrate limited utility and accuracy in clinical practice. This study aims to investigate the correlation between polyamine levels and their key enzymes in the polyamine metabolism pathway with IBD activity, thereby establishing a predictive model for IBD progression through polyamine and metabolite measurements; to estimate the efficacy of biologics via polyamine detection, providing a scientific basis for therapeutic selection; and to screen gut microbiota associated with polyamine metabolic alterations, offering evidence-based guidance for probiotic selection in IBD patients.
