详细描述
This is a pilot feasibility study to determine whether fecal microbiota transplantation (FMT) can suppress or reverse gastrointestinal carriage of MDROs in hospitalized solid organ transplant recipients with a history of one or more MDRO infections.
Study participants who meet inclusion/exclusion criteria and provide written, informed consent will provide a pre-FMT stool sample. Participants will be followed from the time of enrollment up to 3 months post FMT.
Specific organisms of interest that will be tested for by the stool cultures include vancomycin resistant enterococcus, carbapenem resistant Enterobacteriaceae and carbapenem resistant Pseudomonas. Eligible patients who demonstrate colonization with a positive culture for a specific organism of interest will be given FMT.
One FMT dose of a retention rectal enema (OpenBiome) will be administered by a nurse and supervised by our principal investigator and/or sub-investigators trained in performance of FMT.
Stool samples of study participants will be collected and analyzed as follows:

- •Transplant recipient at least >30 days post solid organ-transplant
- •Transplant recipient must be available locally for follow up to 6-months post FMT transplant
- •Inpatient status at time of FMT
- •History of at least one or more treated infections in the last 90 days (bacteremia, UTI, pneumonia or abdominal collection with a positive culture with MDRO) due to an MDRO and the MDRO is likely of enteric origin (carbapenem resistant enterobacteriaceae (CRE), vancomycin resistant enterococci (VRE) or carbapenem resistant Pseudomonas (CRP).
- •Be without active infection for >15 days: bacteremia, UTI, pneumonia or abdominal collection.

- •Patients are not receiving antimicrobials (therapeutic or suppressive) within 48 hours of FMT
- •Solid organ prophylactic antimicrobials as per protocol will be held 24 hours before and 14 days post FMT e.g. trimethoprim/sulfamethoxazole 3x/week or dapsone 100 mg PO daily or weekly for PJP prophylaxis
- •Ganciclovir or valgancyclovir for CMV prophylaxis if required as per protocol can be continued.
- •Patients have a positive surveillance rectal culture for evidence of colonization.

- •Pregnancy or inability/unwillingness to use contraceptives.
- •Autoimmune hepatitis
- •Patients that received a new solid organ transplant within the last 30 days at the time of enrollment
- •Patients on antibiotics treating an active infection or less than 2 weeks at the time of enrollment
- •Any circulatory failure on vasopressors
- •Respiratory failure (on mechanical ventilation) at the time of enrollment
- •Renal failure (GFR <30 or dialysis) at the time of enrollment

- •Patients undergoing treatment for liver or any other organ transplant rejection
- •Patients with graft vs. host disease
- •Patients with any active infection (bacteremia, pneumonia, urinary tract infection or abscess)
- •Life expectancy <1-year post transplant
- •Any clinical significant bleeding from a lower GI source (as defined as requiring blood transfusion, endoscopy or surgical or radiologic intervention) in the last 30 days.
- •Any condition that the physician investigators deems unsafe, feel the risks of outweigh potential benefit, including other conditions or medications that the investigator determines puts the subject at greater risk from FMT
