Clostridium difficile colitis — Clinical Guidelines

Overview

Clostridium difficile colitis is a severe form of antibiotic-associated colitis characterized by inflammation of the colon, often leading to fulminant disease requiring surgical intervention in refractory cases. 1 6

Diagnosis

Clinical symptoms include severe diarrhea, abdominal pain, fever, and leukocytosis.

Elevated white blood cell count and hypoalbuminemia are common laboratory findings. 3

Imaging may reveal signs of toxic megacolon or ascites. 3

Stool cultures and toxin assays confirm C. difficile infection.

Management

First-line treatments: Oral metronidazole or vancomycin for mild to moderate cases. 5

Adjunctive treatments: Fecal microbial therapy (FMT) shows promise, particularly for recurrent or refractory disease. 2

Surgical intervention: Urgent colectomy may be necessary for fulminant colitis unresponsive to medical therapy, with total abdominal colectomy or loop ileostomy with colonic lavage as options. Early surgery before organ failure is associated with improved survival. 1 4

Special Populations

Elderly: Higher risk of mortality; colectomy before organ failure is particularly beneficial in patients over 65 years. 4

Comorbidities: Preoperative multisystem organ failure is a significant predictor of mortality. 3

Key Recommendations

Consider early colectomy in patients with fulminant Clostridium difficile colitis before the onset of organ failure to improve survival rates, especially in elderly patients. (Evidence: Moderate 4)

Utilize fecal microbial therapy (FMT) as an emerging adjunctive treatment for recurrent or refractory C. difficile colitis, acknowledging ongoing research and regulatory considerations. (Evidence: Expert opinion 2)

Monitor closely for signs of multisystem organ failure preoperatively, as this is a critical predictor of postoperative mortality in patients requiring surgical intervention. (Evidence: Moderate 3)
