Brief Summary
In this randomized controlled trial the investigators want to compare the effect of one-time rectal instillation of fecal microbiota transplantation, compared to a ten-day antibiotic course for the treatment of primary Clostridium difficile infection (CDI). The investigators hypothetsize that the instillation of feces from a healthy donor will be non-inferior to vancomycin in inducing a durable cure.

Study Arms (2)
Fecal microbiota transplantation
EXPERIMENTALFecal microbiota from healthy, screened stool donors at the University Hospital of North Norway. Patients will receive one FMT enema immediately after enrolment.
Antibiotic treatment
ACTIVE COMPARATORPatients randomized to the control group will receive a ten-day course of oral vancomycin four times a day. This is according to international guidelines for primary C. difficile treatment.
Interventions
50 g donor feces suspended in saline with added glycerol, administered by a enema kit.
Eligibility Criteria
You may qualify if:
- Patients, ≥18 years with primary C. difficile infection, defined by the following three criteria:
- Diarrhea as defined by the WHO (≥3 loose stools per day), and
- Positive stool test for toxin producing C. difficile, and
- No evidence of previous C. difficile infection during 365 days before enrolment.
- Written informed consent
You may not qualify if:
- Known presence of other stool pathogens known to cause diarrhea.
- Ongoing antibiotic treatment for other infections that cannot be stopped before study treatment administration.
- Inflammatory bowel disease or microscopic colitis.
- \< 3 months life expectancy.
- Serious immunodeficiency, defined as one of the following:
- Ongoing or recent chemotherapy and current or expected neutropenia with neutrophil count of \< 500/μL.
- Active severe immunocompromising disease.
- Inability to comply with protocol requirements.
- Need of intensive care.
- Known irritable bowel syndrome, diarrheal type.
- Pregnancy or nursing.
- Known or suspected toxic megacolon or ileus.
- Total or subtotal colectomy, ileostomy or colonostomy.
- Contraindications for rectal catheter insertion
- Known hypersensitivity or other contraindications to vancomycin
