The primary hypothesis for the study is that pre-operative prophylactic probiotic Lactobacilli tablets will reduce the severity and incidence of endotoxin rise in post cardiopulmonary bypass in cardiac surgery patients.
Endotoxins are large heat stable lipopolysaccharides, which are found in the cell wall of gram negative bacteria. It has been assumed that the intestinal bacteria are the primary source of the plasma endotoxin in cardiac surgery patients.Lactobacilli have been reported as effective in counteracting gram negative bacteria in the gut.Thus Lactobacilli may be effective in reducing the endotoxin rise associated with cardiopulmonary bypass, which may potentially reduce the incidence of the syndrome of generalised inflammation and low systemic vascular resistance post cardiopulmonary bypass.

Preoperative Cardiac Surgery Patients |
Drug: Lactobacillus Probiotic |
Study Type: | Interventional |
Study Design: | Prevention, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study |
Official Title: | The Effect of Prophylactic Pre Operative Probiotic Therapy on Peri Operative Endotoxin Levels in Cardiac Surgery Patients. |
Estimated Enrollment: | 40 |
Study Start Date: | July 2007 |
Estimated Study Completion Date: | December 2007 |
The study compare endotoxin levels of post operative cardiac surgery patients who have received pre operative prophylactic probiotic Lactobacillus tablets. Compared to patients who have received a placebo.
Two different lactobacillus strains will be assessed in the study: Lactobacillus Acidophilus and Lactobacillus Fermentum. There are 4 treatment groups in this study. Lactobacillus Acidophilus,Lactobacillus Fermentum, Lactobacillus Fermentum and Lactobacillus Acidophilus and Placebo.
The probiotic/placebo will be given to the patient 2 a dy for between 2-7 days preoperatively. Participation in this study requires 6 separate blood tests commencing at the start of surgery and continuing for 24 hours immediately post operatively.A total of 30 mls of blood is required.
Ages Eligible for Study: | 18 Years and older |
Genders Eligible for Study: | Both |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Exclusion Criteria:
The Lactobacillus acidophilus preparation to be used in this study contains a very small amount of MSG (total dose 20mg/day, equivalent to 10% of the total dose used to test MSG sensitivity) and as a precaution patients with asthma or recurrent urticaria will be excluded. As the Lactobacillus preparation contains live micro organisms, immunosuppressed and pregnant patients will be excluded.
