Rezidivierende pseudomembranöse kolitis als ursache einer rezidivierenden schweren sepsis

Clostridium difficile (C difficile) colitis accounts for nearly 15-20% of antibiotic-associated diarrhea. Manifestations include asymptomatic carriage, self-limited diarrhea, and pseudomembranous colitis, which is sometimes life-threatening. Despite effective therapy with metronidazole and vancomycin relapse rates are 15-33%. Although colitis is seen in critically ill patients treated with combinations of broad-spectrum antibiotics, reports describing severe sepsis as a result of C difficile infection are limited. We describe the case of recurrent severe sepsis due to recurrent local intestinal C. difficile infection as the only identifiable etiology. The mechanism of severe sepsis may be a derangement of the gastrointestinal barrier function. This could result in absorption of microbes or endotoxin or activation of inflammatory cascades in the submucosa of the intestine or liver. In general, for successful treatment of C difficile infections other than anticlostridial antibiotics should be discontinuated. However, in the present case bacterial translocation from the intestine is an attractive explanation for severe sepsis and therefore additional antibiotics had been administered.
