Which laboratory finding is often seen in patients with fulminant Clostridium difficile infection?

• A. WBC count below 10k
• B. WBC count of 15k
• C. WBC count around 32k
• D. WBC count exceeding 50k

Answer: (C)

In the context of fulminant Clostridium difficile infection, a white blood cell (WBC) count around 32k is commonly observed. This significant elevation in WBC count reflects the severe inflammatory response that occurs in the body due to the infection. Fulminant C. difficile infection is characterized by the rapid onset of severe diarrhea, abdominal pain, and potentially life-threatening complications such as toxic megacolon or colonic perforation.

The elevated WBC count is indicative of the body's attempt to combat the infection, as neutrophils and other immune cells are mobilized. It is important to note that values markedly above the normal range, such as counts exceeding 15k, are often associated with more severe disease courses. WBC counts greater than 30k to 50k can signal critical illness, necessitating immediate medical intervention.

In summary, a WBC count around 32k is a key laboratory finding in fulminant C. difficile infection, reflecting the severity of the illness and the body’s inflammatory response to the pathogenic bacteria.
