ACTIVE_NOT_RECRUITING
Effect of Expanding (Gloving) Barrier Precautions for Reducing Clostridium Difficile Acquisition (and Infection) in VA
Description

Clostridium difficile (C. difficile) is a major pathogen causing serious healthcare-associated diarrheal illness in patients. Prevention of healthcare facility-onset C. difficile infection (CDI) is essential. Many CDI cases are caused by the transmission of the pathogen from patients who carry the bacteria, but do not have symptoms. However, there are limited data on how to prevent the transmission of C. difficile from patients who do not have symptoms. Universal gloving practices - the use of gloves by all healthcare workers for all patient contacts - may reduce CDI cases. In this study, the investigators will examine the effectiveness of universal gloving practices as compared to standard of care (use of gloving for contact only in patients with known CDI or other infections). The investigators will compare the effects of these practices on the transmission of C. difficile within participating hospital units to determine if universal gloving is an effective practice to prevent healthcare-associated CDI.

TERMINATED
Oral Vancomycin for Secondary Prophylaxis of Clostridium Difficile Infection (CDI)

After consenting to participate in the study, participants will be randomized to receive either misoprostol (200 mcg po BID) or matching placebo for 14 days. Participants will be monitored for a total time-period of approximately 9 weeks with the goal of monitoring for recurrence of CDI during an 8-week follow-up period from the time that the course of antibiotic treatment is completed. Patients will have blood and stool samples (or rectal swabs if participants are unable to provide a stool sample) collected throughout the study to assess adherence, biomarkers, and to confirm recurrence of CDI (if necessary).

COMPLETED
Comparison of Ridinilazole Versus Vancomycin Treatment for Clostridium Difficile Infection
Description

Summit is developing ridinilazole as a novel antimicrobial for Clostridioides difficile Infection (CDI), formerly known as Clostridium difficile Infection, with the goal of demonstrating an improved Sustained Clinical Response rate in subjects treated with ridinilazole as compared to subjects treated with vancomycin. A phase 2 proof of concept study, with vancomycin as comparator, demonstrated these attributes with a comparable safety profile. A high fecal concentration of ridinilazole and little systemic exposure were noted. The rationale for this phase 3 study is to confirm the improvement in sustained clinical response of CDI over vancomycin and to compare the safety and tolerability of ridinilazole to that of vancomycin. Ridinilazole plasma concentration will be assessed in a subset of patients.

WITHDRAWN
Use of Bismuth Subsalicylate in Clostridium Difficile Colitis
Description

Clostridium difficle infection is the leading cause of hospital acquired infection and infectious diarrhea in hospitalized patients. Eradication treatment for this infection is the challenging tasks for clinicians due to treatment resistance developed from new hypervirulent strains. The recurrence rate of this infection is around 20% and there is high likelihood(60-70%) of another episode after index recurrence. Given constant challenge new treatment options are under study. Aim of the study is to evaluate if use of bismuth subsalicylate (BSS) can decrease the length of stay in patients admitted with Clostridium difficile infection. Secondarily investigators will also see if there is any impact of BSS in decrease the recurrence.

COMPLETED
TOX NEG Trial: Clostridium Difficile Diagnosis and Treatment
Description

The purpose of this study is to determine the risks and benefits of antibiotic treatment for Clostridium difficile infection (CDI) among patients whose stool samples are nucleic acid amplification test (NAAT) positive and enzyme immunoassay (EIA) negative for C. difficile. Currently, healthcare facilities use a wide variety of tests and strategies for identifying patients with CDI; both EIA and NAAT are widely used. There is no clear gold standard for identifying CDI. At WUSM and BJH, patients are only treated for CDI if they have a positive EIA. However, at many other healthcare facilities, the standard of care is to treat for CDI if the patient is NAAT positive. Some patients who are NAAT-positive may not have true CDI; while this treatment is standard of care at many facilities, the risk and benefits of treating these patients for CDI is unknown. We propose to perform a double blinded, randomized controlled non-inferiority trial of antimicrobial of patients who are EIA negative, NAAT positive to determine the risks and benefits of CDI treatment in this population.
