Which statement best defines fulminant Clostridioides difficile disease?

• A. Fulminant disease with hypotension/shock and ileus requiring aggressive treatment
• B. Outpatient management with oral metronidazole
• C. Recovery within 48 hours with oral vancomycin
• D. No antibiotics, supportive care only

Answer: (A)

Fulminant Clostridioides difficile infection is a rapidly worsening, life-threatening form of CDI. It features hemodynamic instability (hypotension or shock) and ileus or toxic megacolon, so it demands immediate, aggressive management in a hospital setting. The statement that best defines fulminant disease captures both the severe physiological compromise (hypotension/shock) and the presence of ileus, signaling the need for intensive therapy—such as high-dose vancomycin given orally (and via other routes if ileus prevents oral intake), plus consideration of IV metronidazole, aggressive fluid and electrolyte management, vasopressor support as needed, and early surgical consultation for potential colectomy if the patient fails to improve. In contrast, managing as an outpatient, expecting rapid recovery, or withholding antibiotics would be inappropriate for this severe presentation.
