title: Clostridium difficile-associated colitis in uremic patients.
abstract: Five uremic patients managed in a renal unit developed Clostridium difficile-associated colitis. Four cases occurred in a cluster at about the same time. All patients had previously received or were on antibiotic therapy at the onset of diarrhea and one patient was also on oral steroid therapy. Cefotaxime, a third generation cephalosporin was involved in all five cases. All patients had severe diseases with explosive diarrhea and systemic toxicity. The diagnosis was confirmed in all cases by culture of C. difficile and demonstration of high titers of C. difficile cytotoxin in the stool. Histology from rectal biopsy in one patient showed classical pseudomembranous colitis. Response to treatment with vancomycin was generally good though one patient had two relapses. Uremic patients have impaired immune response and intestinal motility and are predisposed to C. difficile infection. Cross-infection can occur and the isolation of affected patients seems prudent.
