Faecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection (CDI). Now, a multicentre study aimed to investigate whether FMT could be used as treatment in severe and/or complicated cases of CDI. The researchers found that FMT was safe and effective in this patient population (n = 17 total; mean follow-up 11.4 months). Primary and secondary cure rates were 88.2% and 94.1%, respectively, and no adverse effects directly related to FMT were observed.
