A Rare Case of Clostridium difficile Enteritis: A Common Bug in an Uncommon Place

Clostridium difficile (CD), a bacterium responsible for causing 15%-25% of all cases of infectious diarrhea, is most commonly associated with infection of the colon. Rarely, though with increasing frequency, it has been noted to infect the small intestine in what is referred to as CD enteritis. We present the case of a patient who was diagnosed and treated for CD enteritis, review the pathophysiology behind the infection, and discuss the diagnostic and treatment options available to healthcare professionals.

Atypical Presentation of C. Difficile Infection: Report of a Case with Literature Review

Clostridium difficile (C. difficile) is a gram-positive, obligate, anaerobic spore-forming bacillus first reported by Hall and O'Toole in 1935. It occurs mostly after antibiotic use and invariably presents with watery diarrhea. We describe an atypical presentation of C. difficile in a 64-year-old Caucasian female who presented to the our emergency department with abdominal pain, nausea, and vomiting for one day. A complete blood count revealed leukocytosis 30 x 10⁹/L and a subsequent computed tomography (CT) scan of the abdomen and the pelvis, showed fluid filled small bowel loops consistent with enteritis. Her presentation was unusual for lack of diarrhea, the hallmark of C. difficile infection. She was admitted and treated with oral vancomycin. The polymerase chain reaction (PCR) value in the stool for C. difficile was positive. The patient responded very well: her abdominal pain resolved and leukocyte count normalized after a few doses of vancomycin (125 mg po qid). The patient's progress was followed in our clinic for the last three months.
