From the Guidelines

Yes, Clostridioides difficile (C. diff) colitis can cause sepsis.

Sepsis in C. diff Colitis

  • C. diff colitis can lead to severe complications, including toxic megacolon, peritonitis, and septic shock 1.
  • The development of sepsis in C. diff colitis is often associated with systemic symptoms, such as fever, leukocytosis, and hypoalbuminemia 1.
  • Fulminant colitis is a severe form of C. diff colitis that can progress to multiple organ failure and increased mortality 1.

Risk Factors for Sepsis

  • Leukocytosis (WBC > 15 × 10^9/L) and renal failure are useful predictors of severe C. diff colitis and sepsis 1.
  • Hypoalbuminemia (albumin < 2.5 g/dL) is also a predictor of severe C. diff colitis and sepsis, as human serum albumin can bind C. difficile toxin A and B, impairing their internalization into host cells 1.

Management of Sepsis in C. diff Colitis

  • Early diagnosis and treatment are crucial in reducing mortality associated with fulminant colitis and sepsis 1.
  • Surgical management may be necessary in cases of fulminant colitis with systemic toxicity, and resection of the entire colon should be considered in these cases 1.
  • Diverting loop ileostomy with colonic antibiotic lavage is an effective alternative to subtotal colectomy in some cases 1.

From the Research

C. diff Colitis and Sepsis

  • C. diff colitis can cause sepsis, as reported in several studies 2, 3, 4
  • The mechanism of sepsis may be related to the derangement of the gastrointestinal barrier function, leading to absorption of microbes or endotoxin, or activation of inflammatory cascades 2
  • Severe C. diff infection can result in death, and treatment includes management of severe sepsis and shock, pathogen-directed antibiotic therapy, and surgical intervention in selected cases 3

Clinical Presentations

  • C. diff infection can present with a range of symptoms, from self-limiting diarrhea to fulminant disease, including toxic megacolon or pseudo-membranous colitis 5, 6
  • Septic shock from C. diff colitis can occur even in healthy individuals without traditional risk factors 4
  • Accurate diagnosis of C. diff infection depends on selecting patients with high pre-test probability, collecting an acceptable stool specimen, and understanding current test methods 5

Diagnosis and Treatment

  • Diagnosis of C. diff infection is based on laboratory tests, including enzyme immunoassays, molecular assays, and toxin tests 5, 6
  • Treatment of C. diff infection includes antimicrobial therapy, and prevention is key to limiting the devastating effects of the disease 3, 6
