[Inflammatory bowel disease and Clostridium difficile: be prepared].

In this report we describe 3 female patients, aged 38, 29 and 91, with inflammatory bowel disease (IBD) and suffering from an episode of abdominal symptoms and diarrhoea. This raised suspicion of a flare-up of IBD, but all three proved to have Clostridium difficile-associated disease (CDAD). This diagnosis led to a change in management, medication being changed from ciprofloxacin into metronidazole in 2 patients. Patients known to have IBD often present with abdominal pain and diarrhoea. In such a situation an exacerbation of the IBD usually seems most likely. However, an infection with C. difficile always has to be considered, since this infection can mimic a flare-up of IBD. There is a rising incidence of C. difficile in patients with IBD. C. difficile infections in IBD-patients tend to run a more severe course. Therefore, early diagnosis of CDAD in IBD patients is important and has distinct therapeutic implications.
