Background:
Clostridioides difficile infections (CDIs) are common among patients with inflammatory bowel disease (IBD) and can mimic and exacerbate IBD flares, thus warranting appropriate testing during flares.
Aims:
To examine recent trends in rates of CDI and associated risk factors in hospitalized IBD patients, which may better inform targeted interventions to mitigate the risk of infection.
Methods:
This is a retrospective analysis using the Nationwide Readmissions Database from 2010 to 2020 of hospitalized individuals with Crohn's disease (CD) or ulcerative colitis (UC). Longitudinal changes in rates of CDI were evaluated using International Classification of Diseases codes. Multivariable logistic regression evaluated the association between patient- and hospital-related factors and CDI.
Results:
There were 2,521,935 individuals with IBD who were hospitalized at least once during the study period. Rates of CDI in IBD-related hospitalizations increased from 2010 to 2015 (CD: 1.64%-3.32%, p < 0.001; UC: 4.15%-5.81%, p < 0.001), followed by a steady decline from 2016 to 2020 (CD: 3.15%-2.27%, p < 0.001; UC: 5.04%-4.27%, p < 0.001). In multivariable models, CDI was associated with the Charlson-Deyo comorbidity index, public insurance, and hospital size. CDI was associated with increased mortality.
Conclusions:
Rates of CDI among hospitalized patients with IBD had initially increased, but have declined since 2015. Increased comorbidity, large hospital size, public insurance, and urban teaching hospitals were associated with higher rates of CDI. CDI was associated with increased mortality in hospitalized patients with IBD. Continued vigilance, infection control, and treatment of CDI can help continue the trend of declining infection rates.

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
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
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...

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...

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
