Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Drug: Vancomycin
  • Dietary Supplement: Culturelle
  • Drug: Vancomycin Placebo
  • Drug: Probiotic Placebo
Early Phase 1

Detailed Description

In this study, patients will be screened for C. difficile colonization

  • Outcome Measures

    Primary Outcome Measures

    1. Number of patients identified and randomized to a treatment arm within 72 hour of beginning a systematic antibiotic. [1 year]

      Feasibility will be assessed using the following parameters: Proportion of eligible participants screened that are randomized within 72 hours of antibiotic exposure (goal ≥ 90%) Proportion of participants receiving all doses of study medication (goal ≥ 90%) Proportion of participants with complete follow up at 14 days (goal ≥ 95%)

    2. Development of C difficile associated diarrhea within 14 days of randomization [1 year]

      Development of C difficile associated diarrhea within 14 days of randomization to one of the treatment arms as defined by the Provincial Infectious Diseases Advisory Committee (PIDAC)

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    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
