Introduction:
Clostridioides difficile infection (CDI) is a major complication in patients with inflammatory bowel disease (IBD), contributing to increased morbidity, mortality, and health care burden. This study aimed to evaluate national trends and clinical outcomes associated with CDI in hospitalized IBD patients in the United States.
Methods:
We conducted a retrospective cohort study using the National Inpatient Sample (NIS) from 2012 to 2021. Adult patients hospitalized with a primary or secondary diagnosis of IBD (Crohn's disease or ulcerative colitis) were stratified into 2 groups by the status of CDI diagnosis (either primary or secondary diagnosis). Demographic characteristics, hospital outcomes, and complications were compared between CDI and non-CDI cohorts. Multivariable logistic regression was used to identify independent predictors of in-hospital mortality, septic shock, and venous thromboembolism (VTE).
Results:
Among 4,193,564 hospitalized IBD patients, 534,190 (12.7%) had CDI. CDI patients were older (mean: 68.8 vs 53.3 y, P < 0.001), with higher in-hospital mortality (3.6% vs 2.0%, P < 0.001), VTE (23.7% vs 6.2%, P < 0.001), septic shock (5.4% vs 4.0%, P < 0.001), and mechanical ventilation use (4.2% vs 2.8%, P < 0.001). Ulcerative colitis was more frequently associated with CDI than Crohn's disease (30.3% vs 25.0%, P < 0.001) and independently predicted septic shock (OR: 1.09) and VTE (OR: 1.06) but was associated with lower mortality (OR: 0.81).
Conclusion:
The presence of CDI in hospitalized patients with IBD led to significantly worse outcomes. Ulcerative colitis is more commonly associated with CDI and increased risk of complications. These findings highlight the need for early detection, preventive strategies, and tailored management of CDI in the IBD population.

01:30Inflammatory Bowel Disease II: Crohn's Disease
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 is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

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...

Diagnostic studies
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...
