Clostridioides difficile infection [5] (CDI or C-diff), also known as Clostridium difficile infection, is a symptomatic infection due to the spore-forming bacterium Clostridioides difficile. [6] Symptoms include watery diarrhea, fever, nausea, and abdominal pain. [1] It makes up about 20% of cases of antibiotic-associated diarrhea. [1]
Clostridioides difficile (syn. Clostridium difficile) is a bacterium known for causing serious diarrheal infections, and may also cause colon cancer. [ 4 ] [ 5 ] It is known also as C. difficile , or C. diff ( / s iː d ɪ f / ), and is a Gram-positive species of spore -forming bacteria. [ 6 ]
Clostridioides difficile, also known more commonly as C. diff, accounts for 10 to 20% of antibiotic-associated diarrhea cases, because the antibiotics administered for the treatment of certain disease processes such as inflammatory colitis also inadvertently kill a large portion of the gut flora, the normal flora that is usually present within the bowel.
Infection should be ruled out with stool studies, including Clostridioides difficile, bacterial culture, ova and parasites. Symptoms of upper abdominal pain, nausea or vomiting warrant evaluation with upper endoscopy. Treatment of immune checkpoint inhibitor colitis is based on severity, as defined by the grade of diarrhea and colitis.
FMT is an effective treatment for Clostridioides difficile infection (CDI). [3] [4] [5] For recurrent CDI, FMT is more effective than vancomycin alone, and may improve the outcome after the first index infection. [3] [5] [6] Side effects may include a risk of infections, therefore the donor should be screened for pathogens. [7]
Alternative causes of colitis should be considered, such as ischemic colitis (inadequate blood flow to the colon), radiation colitis (if prior exposure to radiation therapy), or chemical colitis. Pseudomembranous colitis may occur due to Clostridioides difficile infection following administration of antibiotics.
Bezlotoxumab is indicated to reduce recurrence of Clostridioides difficile infection in people who are receiving antibacterial drug treatment for Clostridioides difficile infection and are at a high risk for Clostridioides difficile infection recurrence. [3]
Generalised inflammation of the large intestine is referred to as colitis, which when caused by the bacteria Clostridioides difficile is referred to as pseudomembranous colitis. Diverticulitis is a common cause of abdominal pain resulting from outpouchings that particularly affect the colon.
