Background:
The clinical course of inflammatory bowel disease (IBD) varies widely, and identifying factors associated with severe disease is essential for risk stratification. Diabetes has been proposed as a potential determinant of adverse outcomes, yet its independent role in disease progression remains unclear.
Methods:
We retrospectively analyzed clinical data from patients with mild and severe IBD. Demographic, inflammatory, hepatic, and metabolic parameters were compared between groups. Logistic regression was used to identify independent predictors of severe IBD. Model performance was assessed using receiver operating characteristic curves, calibration analysis, and cross-validation. An inflammation-metabolism-liver coupling index (IMLCI) was constructed to integrate key predictors.
Results:
Patients with severe IBD exhibited significantly higher levels of inflammatory markers (WBC, neutrophil percentage, CRP), impaired hepatic function indices (ALT, AST, bilirubin), and adverse metabolic profiles (elevated TG and LDL, reduced HDL and vitamin B12). Diabetes was strongly associated with severe IBD (odds ratio = 3.81, P < 0.001), confirming its independent effect beyond traditional risk factors. The inflammation-metabolism-liver coupling index (IMLCI) demonstrated excellent discrimination (AUC = 0.900 in the training cohort and 0.891 in the testing cohort), good calibration (Hosmer-Lemeshow P = 0.83), and robust internal validation, outperforming single laboratory or metabolic biomarkers.
Conclusion:
Diabetes represents a strong independent risk factor for severe IBD. The proposed IMLCI framework, integrating inflammation, metabolism, and liver function, demonstrates high predictive accuracy and may provide a practical tool for early identification and risk management of patients with severe IBD.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
