To determine the safety and effectiveness of the probiotic VSL#3 in adults with irritable bowel syndrome (IBS).
The subjects will be randomized into either a 4 week or 8 week treatment period with the probiotic. The treatment will be open label. They will take 2 packets once daily.
Other Name: VSL#3
Recent studies performed outside the U.S. and/or prior to recent FDA requirements suggest that the probiotics in VSL#3 may be effective in IBS in adults. Because there is a significant unmet need for improved IBS therapies to prevent frequent exacerbations that lead to unscheduled health care, we will conduct a safety study of the probiotic VSL#3. Preliminary studies suggest that probiotics such as VSL#3 are effective in the treatment of adults with IBS but safety studies have not been carried out. A safety study of VSL#3 has been carried out in adult asthmatics that demonstrated no significant adverse effects. Before a trial of VSL#3 can be performed in children with IBS, the FDA has requested that a safety trial be conducted in adults with IBS.
Consent will be obtained from the subject.
Adults who meet the criteria for irritable bowel syndrome will be recruited and studied. They will have been diagnosed by an adult gastroenterologist.
During a baseline one week period, the subjects will keep a diary of pain episodes, pain severity, pain-induced interference with activity, and stooling pattern (i.e., pain/activity/stool diary).
Following the baseline period, the subjects will be randomized into either a 4 week or 8 week treatment period with the probiotic. The treatment will be open label. During the treatment period, subjects will keep the diary for pain and stooling habits and a daily record of symptoms (i.e., daily temperature monitoring).
At the end of the treatment period the pain/stool/activity diary will be repeated. Four weeks after the treatment period ends a follow-up phone call will be made to participants to check on their pain and stooling patterns.
