Oral Vancomycin Versus Probiotics Versus Placebo for Prevention of Clostridium Difficile Infection in Colonized Patients (Decency-RCT)
September 20, 2023 updated by: Hamilton Health Sciences Corporation
Oral Vancomycin Versus Probiotics Versus Placebo for Prevention of Clostridium Difficile Infection in Colonized Patients (Decency-RCT): A Randomized Controlled Pilot Trial
The goal of this pilot study is to assess the feasibility of randomizing hospitalized patients that are colonized with C. difficile and started on systemic antibiotics to either a probiotic, oral vancomycin, or placebo in a parallel-group 1:1:1 design.
The ultimate goal is to conduct an appropriately-powered RCT to determine the optimal method for reducing C difficile infection in colonized patients.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Adult patients of 18 years of age or older identified as asymptomatic carriers of C. difficile (i.e. not meeting case definition of C. difficile infection, see below)
- Started on systemic (oral or intravenous) antibiotics for any (presumed) bacterial infection
- Patient must have vitals (heart rate, blood pressure, temperature), estimated creatinine clearance (using the Chronic Kidney Disease Epidemiology equation (CKD-Epi)) and a complete blood count available within 24 hours of enrolment
Exclusion Criteria:
- On a course of systemic antibiotics that had been started more than 72 hours ago (as current evidence suggests that the earlier probiotics are started, the more efficacious they are)
- Patient with C. difficile, i.e. presence of diarrhea (three or more loose or watery stools within 24 hours), or fevers or hypotension from C. difficile infection
Any patients with contra-indications to probiotics or vancomycin:
- Immunosuppressed (primary or acquired immunodeficiency, including AIDS (defined as AIDS defining condition or cluster of differentiation 4 (CD4) nadir of <200/ul), hematologic malignancies, long-term systemic corticosteroid treatment, active treatment with chemotherapeutic agents or biologicals, autoimmune diseases, nephrotic syndrome)
- Structural heart disease (e.g. atrial septal defect, ventricular septal defect)
- Gastroesophageal or compromised gut integrity (e.g. short gut syndrome, intestinal injury or dysfunction, inflammatory bowel diseases including current or past history of Crohn's disease and ulcerative colitis)
- Patients on systemic aminoglycosides, ethacrynic acid, polymixin B, or colistin.
- Prior or current hearing loss
- Female patients with known pregnancy or who are planning to get pregnant, or who are breastfeeding
- Patients with end-stage renal diseases defined as an estimated glomerular filtration rate of <15ml/min, or absence of a current estimated creatinine clearance
- History of an allergic reaction to one of the study drugs, or sensitivity to milk
- Patients started on probiotics or oral vancomycin while in hospital
