Introduction: Fecal microbiota transplantation (FMT) is established as an effective treatment for recurrent Clostridioides (formerly Clostridium) difficile infection (CDI). Incidence and mortality from CDI are significantly higher in the elderly population (CDI is 10 times more common and 92% of CDI-related deaths occur in the elderly). Risk of cardiopulmonary complications from sedation prior to colonoscopy is increased in the elderly. Efficacy and safety of FMT via colonoscopy in the elderly are unknown

Methods: A retrospective study comparing patients ≥75 years, and patients < 75 years who had FMT at Sanford Medical Center, Sioux Falls, SD, between 2013-2018. All patients underwent FMT via colonoscopy. Antibiotics prior to FMT, donor screening, preparation and delivery of FMT, and post-procedural follow up were based on a standardized protocol in our institution. Data on baseline characteristics, co-morbidities, antibiotics-associated with CDI, safety, and success rate of treatment (defined by resolution of symptoms and absence of CDI recurrence at 8 and 52 weeks) were collected

Results: Of 59 patients, 17 (28.8%) were ≥75 years with a mean age of 84.4 years, and 42 (71.2%) were < 75 years and a mean age of 46.4 years. Baseline characteristics of both groups are described in Table1. Number of CDI before FMT, history of severe CDI, nosocomial CDI were similar. No fulminant CDI was reported in our study. In ≥75 years vs. < 75 years, serum albumin was lower (3.4 vs 4 g/dl, P< 0.002) and hypertension was more common (52.9 vs 23.8%, P=0.03). 80% of our study population had a history of antibiotics exposure prior to CDI, but there was no statistically significant difference between groups. Of antibiotics-associated with CDI, penicillins were more likely to be reported in ≥75 vs. < 75 years (38.1 vs 5.9 %, P=0.014). Cephalosporins, macrolides, fluoroquinolones, and clindamycin were similar in both groups. Prior to FMT, both groups were treated similarly with vancomycin with or without taper, oral or intravenous metronidazole, or fidaxomicin. No major complications related to anesthesia or FMT via colonoscopy or deaths attributed to FMT were reported in our study. The success rates at 8 and 52 weeks in both groups were similar (76.5 vs. 83.3%, and 76.5 vs. 71.4%, respectively)

Discussion: Despite the increased risk of CDI and colonoscopy in the elderly population, success rate and safety of FMT appears to be equivalent between elderly and non-elderly. Prospective studies with larger sample size are needed
