Fatal Community-Acquired Clostridioides difficile Infection as a Cause of Listeria Meningitis: A Case Report.

A 77-year-old woman with a history of total gastrectomy was transferred to our hospital with complaints of fever and consciousness disturbance for five days. She had fever and consciousness disturbance with positive meningeal signs. Laboratory findings indicated an elevated inflammatory response and hypoalbuminemia, and computed tomography (CT) of the body indicated intestinal gas retention and mild ascites. Cerebrospinal fluid analysis revealed pleocytosis with elevated protein levels and a diagnosis of Listeria meningitis was made. Treatment with ampicillin/sulbactam was started, and her fever and consciousness disturbance resolved on day 2. However, on day 3, her fever and conscious disturbance deteriorated, and she went into shock subsequently. Laboratory findings revealed deteriorated inflammatory response and hypoalbuminemia. Body CT showed an obvious distended bowel loop and intestinal edema. A stool culture revealed positive Clostridioides difficile toxin B, and we diagnosed her with Clostridioides difficile infection (CDI). Although intravenous metronidazole was initiated, she died due to prolonged hypovolemic shock. We considered she had community-acquired CDI because her CDI emerged immediately after the initiation of antibiotics, symptom deterioration within 48 hours of admission, and abnormal abdominal CT findings at admission. Listeria meningitis can develop based on community-acquired CDI. Because CDI can have a very rapid and fatal course and is sometimes complicated by other infectious diseases, clinicians should pay attention to this complication.
