The first Danish case of severe Clostridium difficile-associated diarrhoea (CDAD) caused by the virulent PCR ribotype 027 (CD027) strain was reported. The patient recovered fully after treatment with metronidazole.
Area of Science:
- Infectious Diseases
- Microbiology
- Gastroenterology
Background:
- Clostridium difficile-associated diarrhoea (CDAD) rates have increased globally since 2003.
- A hypervirulent strain, PCR ribotype 027 (CD027), is linked to severe CDAD cases.
- The emergence of CD027 poses a significant public health challenge.
Observation:
- The first documented case of CDAD caused by CD027 in Denmark is presented.
- An 85-year-old female patient admitted for pneumonia developed severe, bloody diarrhoea.
- Antibiotic treatment with penicillin and moxifloxacin preceded the onset of diarrhoea.
Findings:
- Stool sample analysis confirmed the presence of the CD027 strain.
- The patient received a ten-day course of metronidazole.
- Complete recovery from CDAD symptoms was achieved.
Implications:
- This case highlights the geographical spread of the CD027 strain.
- Early diagnosis and appropriate treatment are crucial for managing severe CDAD.
- Surveillance for CD027 is important for public health in Denmark and beyond.
