title: Serum markers for severe Clostridium difficile infection in immunosuppressed hospitalized patients.
abstract: Clostridium difficile infection (CDI) has emerged as the leading cause of nosocomial diarrhea in the developed world. The prompt recognition of severe CDI is essential in providing early aggressive therapy. Though previous studies have identified leukocytosis, azotemia, and hypoalbuminemia as markers to differentiate severe from non-severe CDI in the general patient population, there is little data in immunosuppressed patients. We conducted a retrospective chart review of immunosuppressed patients with CDI to identify serum markers associated with severe CDI. Twenty-nine immunosuppressed patients with CDI (nine with severe disease) were identified. Those with severe disease were older and had evidence of renal dysfunction. The white blood cell count, platelet, and albumin levels were the same in the severe and non-severe immunosuppressed CDI patients. Therefore, recognized serum markers of severe CDI are not universally useful in immunosuppressed patients. Moreover, the clinician must be aware that immunosuppressed patients can develop severe CDI while remaining leukopenic.
