  Purpose

Main research Question: The investigators would like to find out if both the Bio-K (lactobacillus acidophilus and lactobacillus casei) drink and capsule are equally effective in the prevention of diarrhea associated with antibiotic use.

Why is this research project important? About 25% of patients who use antibiotics may develop diarrhea as a side effect. Symptoms are mild and consist of watery diarrhea and abdominal pain. Some patients may develop a more severe form of diarrhea, called clostridium difficile-associated diarrhea. Clostridium difficile-associated diarrhea may lead to more serious consequences like inflammation of the large bowel and in some cases, death. There are some studies that suggest Bio-K drink, a probiotic preparation containing lactobacillus acidophilus and lactobacillus casei, decreases the risk of diarrhea from antibiotic use. As a result, St. Joseph's Healthcare has recently to use Bio-K routinely to try to reduce risk of patients developing diarrhea. No other Hamilton hospitals use Bio-K routinely as there is not strong evidence about the effectiveness of Bio-K for the prevention of diarrhea. This study will provide more information about Bio-K's effectiveness in the prevention of diarrhea associated with antibiotic use as both a capsule and a drink.

Primary Outcome Measures:
  • Antibiotic-associated diarrhea [ Time Frame: 30 days after termination of antibiotic ] [ Designated as safety issue: No ]

Estimated Enrollment: 90
Study Start Date: February 2009
Estimated Study Completion Date: May 2009
Estimated Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bio-K capsule
1 capsule of lactobacillus acidophilus and lactobacillus casei (50 billion live bacteria) daily for duration of antibiotic therapy and 7 days after or until discharge, whichever comes first
 Dietary Supplement: Bio-K capsule formulation
Bio-K 1 capsule formulation daily for the duration of antibiotic treatment and for 7 days after termination of antibiotics or until hospital discharge, whichever occurs first
Active Comparator: Bio-K liquid
98 g of lactobacillus acidophilus and lactobacillus casei (50 billion live bacteria) daily for the duration of antibiotic treatment and for 7 days after termination of antibiotics or until hospital discharge, whichever comes first
 Dietary Supplement: Bio-K drink
Bio-K 98 g of diary-free soy beverage formulation for the duration of antibiotic treatment and for 7 days after termination of antibiotics or until hospital discharge, whichever occurs first
No Intervention: no Bio-K
No lactobacillus product - standard infection control procedures (i.e. handwashing, etc.)
