[Life-threatening complications of Crohn's disease and ulcerative colitis: a systematic analysis of admissions to an ICU during 18 years]

BACKGROUND AND OBJECTIVE: Despite numerous publications on the epidemiology of inflammatory bowel diseases (IBD) there is a lack of systematic investigations on live-threatening complications of IBD and their causes. This study evaluates risk factors, course and outcome in intensive-care patients which were related to complications of IBD. PATIENTS AND METHODS: Among 6071 admissions to the intensive-care unit (ICU) of a gastroenterological department (university hospital with IBD-outpatient unit) between 1.1.1991 and 31.1.2008 36 ICU admissions of 28 patients with IBD were documented and prospectively analysed from 1996 onwards, using a structured questionnaire on causes for ICU admission as well as risk factors regarding death, organ failure and length of ICU stay. RESULTS: ICU admissions of IBD patients mainly resulted from three causes: complications specific to IBD (44 %), including acute flare-up, perforation and electrolyte imbalance, septic complications (22 %) and thromboembolic complications (17 %). Five patients died, all from septic complications related to immunosuppression including candida sepsis, varicella pneumonia during treatment with infliximab, and pneumocystis pneumonia related to treatment with azathioprine. The most important risk factors according to uni- and multivariate analyses were old age on ICU-admission and first diagnosis of IBD, previous surgery related to IBD and Crohn's disease. CONCLUSIONS: Complications of both IBD and immunosuppressive therapy may be live-threatening in patients with IBD. Better characterization of patients with a high probability of improved outcome by immunosuppressive and/or antibody-therapy seems to be preferable to noncritical early use of these drugs.     «
