Community-acquired fulminant Clostridioides (Clostridium) difficile infection by ribotype 027 isolate in Japan: a case report

Abstract

BACKGROUND Clostridioides (Clostridium) difficile infection (CDI) has become an increasingly significant disease not only as healthcare-associated infection, but also as community-acquired (CA) infection worldwide. CDI caused by the NAP1/BI/027 strain is reported to be more severe, difficult to cure, and frequently associated with recurrences in North America and Europe. CASE PRESENTATION A 68-year-old woman was referred to our hospital for continuous lower abdominal pain 4 weeks after eradication therapy against Helicobacter pylori. While she was treated with fasting on the suspicion of ischemic colitis, she experienced septic shock. Emergent subtotal proctocolectomy revealed fulminant pseudomembranous C. difficile colitis. The C. difficile isolate recovered from the patient was identified as ribotype 027, which has been reported to be uncommon in Japan. CONCLUSION We report a rare case of CA fulminant pseudomembranous colitis caused by ribotype 027 C. difficile after H. pylori eradication therapy.
