Scientific titleA double blind, randomised, placebo controlled trial investigating the efficacy and role of Synbiotic Cocktail 2000 in the treatment of Clostridium difficile diarrhoea and colitis
Study objectives1. To assess the role of Synbiotic Cocktail 2000 on symptom duration and relapse rates in patients with one or more episodes of C. difficile diarrhoea
2. To confirm the safety, tolerance and efficacy of Synbiotic Cocktail 2000 used with metronidazole for treatment of C. difficile diarrhoea and colitis compared with metronidazole and placebo
3. To assess the rate of C. difficile toxin and C. difficile elimination with Synbiotic Cocktail 2000 when compared to placebo
4. To investigate the ability of Synbiotic Cocktail 2000 to inhibit C. difficile and Toxin A production in vitro
5. To investigate the efficacy and duration of human gut colonisation by Synbiotic Cocktail 2000 during and after treatment
6. To investigate and characterise mucosa-associated bacteria in patients with antibiotic associated colitis before and after treatment with Synbiotic Cocktail 2000

Health condition(s) or problem(s) studiedClostridium difficile diarrhoea and colitis
InterventionTreatment will be initiated at the time of acute relapse and patients will commence on oral metronidazole with either probiotic or placebo. Antibiotic therapy will be continued for seven days while probiotic or placebo will continue for three weeks. Any relapse in symptoms will require oral vancomycin. Stool samples will be obtained daily during initial metronidazole therapy until two stool samples are negative for C. difficile toxin. Daily stool diaries will be kept by all patients. At the end of the three week period of probiotic therapy, patients will undergo a rigid sigmoidoscopy examination and one rectosigmoid biopsy obtained for culture.
Intervention typeOther
Primary outcome measureDisease relapse over one month
Secondary outcome measures1. Disease relapse over three months
2. Rate of loss of C. difficile and toxin from the stool
