Background: Clostridium difficile infection (CDI) carries a large burden on the national public health with its high morbidity and mortality rates. Patients with inflammatory bowel disease (IBD) are generally at higher risk of infection, recurrence and complications. Therefore, the need for more reliable and safe therapy is necessary. Our study aims to evaluate long-term fecal microbiota transplant (FMT) outcomes in the general population compared to patients with IBD.

Methods: A single center long-term follow-up study was conducted to evaluate the outcomes of FMT in patients with and without IBD. Prior to FMT data including demographics, prior treatment of CDI and severity of symptoms were gathered via chart review. Post FMT, all patients were surveyed after 2 days, 30 days and > 1 year to assess clinical and laboratory response. Our study outcomes included primary cure rate (negative CDI testing > 1 year after single FMT), and secondary cure rate (negative CDI testing > 1 year after repeat FMT or after an additional course of antibiotic with or without repeat FMT).

Results: Seventy-eight patients with recurrent or refractory CDI and subsequent FMT treatment were included. Mean age was 57 years, and 69% were females and twenty-one (27%) had IBD. Primary cure rate was achieved in 77% of the cases while secondary cure rate reached 100% at the end of the study. IBD patients were younger with an average age of 47 years, and had more complains of abdominal pain (71%), and required escalation of therapy in 50% of patients.

Conclusions: FMT was effective in the eradication of CDI in patients with and without IBD, but with no significant symptoms improvement in patients with IBD. Future randomized control studies are needed to examine the long-term progression of IBD and quality of life in patients treated with FMT compared to standard therapy of antibiotics for recurrent CDI.
