Objectives:
Clostridium difficile infection (CDI) is a common complication in inflammatory bowel disease (IBD) and has been associated with poor IBD outcome. The aims of our study were to look for predictive factors of CDI in patients hospitalized for IBD flare and to evaluate a rapid testing strategy in this population.
Methods:
Consecutive patients hospitalized for IBD flare in Saint-Antoine Hospital (Paris, France) were prospectively tested for CDI with a defined strategy involving rapid testing and reference methods. Risk factors for CDI were investigated and performances of diagnostic tests were evaluated.
Results:
C. difficile testing was performed at admission in 461 hospitalizations for IBD flare. CDI was diagnosed in 35 cases (7.6%) and non-toxigenic C. difficile was identified in 10 cases (2.2%). In multivariate analysis, UC phenotype was associated with CDI (OR 2.2, 95% CI 1.03-4.6, p=0.047). Glutamate dehydrogenase (GDH) test had a 97.1% sensitivity and a 100% negative predictive value for CDI diagnosis but a positive predictive value of 79.1%. Enzyme immunoassay (EIA)-based toxin detection (C. Diff Quik Chek complete®, Alere) had a poor sensitivity and diagnosis was rescued by toxin PCR in 100% of cases.
Conclusion:
CDI is frequent in patients hospitalized for IBD flare. Clinical parameters do not help for the diagnosis and rapid testing should be performed in all patients. Currently, a negative result of an EIA-based toxin search associated with a positive GDH test cannot rule out a CDI and should not delay initiation of specific treatment in case of severe symptoms or high presumption.

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...
