Clinical Trial Summary

The goal of this study is to evaluate whether using vancomycin orally can prevent CDI in patients who are colonized with C. diff who are admitted to the hospital and need antibiotics for another infection.

Description:

Screening to Prophylax against CDI (SToP CDI) is a prospective, single-center, double-blinded, randomized, placebo-controlled study of the effectiveness of vancomycin vs. placebo for preventing CDI in patients colonized with toxigenic C. difficile and receiving high-risk antibiotics. The investigators plan to screen 2500 patients to randomize 200. Consented patients will have a stool sample collected and tested for presence of toxigenic C. difficile by PCR. Patients who test negative will simply be followed for development, severity and outcome of CDI. Patients who test positive (are colonized with C. difficile) will be randomized to one of two arms: Arm 1: Patients receive 125 mg vancomycin PO q6 hours as prophylaxis against C. difficile for the duration of their antibiotic treatment +3 days. Arm 2: Patients receive placebo PO q6 hours for the duration of their antibiotic treatment +3 days.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The incidence of CDI in inpatients receiving vancomycin prophylaxis vs. placebo who are on high-risk antibiotics and are colonized with toxigenic C. difficile.	Number of participants with CDI in this subgroup of patients as assessed by clinical presentation, PCR testing of stool, and EIA test for production of toxins. Patients are considered to have CDI if they have a positive PCR test, a positive toxin EIA, and clinical symptoms compatible with CDI.	12 weeks after treatment
Secondary	The severity of CDI in patients receiving vancomycin prophylaxis vs. placebo.	Number of participants with mild, moderate, severe or fulminant disease after treatment	12 weeks after treatment
Secondary	The outcome of CDI in patients receiving vancomycin prophylaxis vs. placebo.	Number of participants who developed C difficile infection after treatment.	12 weeks after treatment
Secondary	The prevalence of toxigenic C. difficile colonization among the inpatient population treated with high-risk antibiotics based on C. difficile PCR.	Number of participants who remained colonized with C. difficile after treatment	12 weeks after treatment
Secondary	The incidence of CDI in patients initiated on high risk antibiotics who are not colonized with toxigenic C. difficile.	Number of participants who developed CDI in this subgroup of patients as assessed by clinical presentation and PCR testing of stool. Patients are considered to have CDI if they have a positive PCR test and clinical symptoms compatible with CDI.	12 weeks after antibiotics
