Gastroenterol. 105 (7): % reduction in AAD duration (with 2 capsules) Reduction of GI symptoms (commonly associated to IBS) (%) Placebo (n=84) 1 capsule (n=85) 2 capsules (n=86) Abdominal pain Bloating Liquid stools I leus P < 0.05 : All Clinical studies with Bio-K+ ® AAD duration (days) Dose response efficacy of Bio-K+ ® on AAD duration and GI symptoms Placebo 1 capsule 50B 2 capsules 50B

10 Pierre-Le Gardeur Hospital experience 10 Maziade et al Submitted to Infect. Control Hosp. Epidemiol. 7 years of Clostridium difficile infection prevention in a community hospital – Role of a proprietary probiotic formula of Lactobacillus acidophilus CL1285 and Lactobacillus casei LBC80R Maziade PJ, Andriessen A, Gagné D, Murray G, Jacob C, Pereira P and Méthot L. Protocol: Hospitalization + Antibiotics Bio-K+ ®  CDI cases =  73%  Severe CDI cases =  94%  Mortality rate =  91%  Recurrent CDI =  39%

11 Evolution of CDI incidence 11 Maziade et al Submitted to Infect. Control Hosp. Epidemiol. CDI/10,000 patient-days Pierre-Le Gardeur Hospital

12 Enhancing pharmacology of ARVs using evidence- based probiotics HIV mediated loss of Th17 cells from GALT during acute infection 4  Impairs mucosal integrity and innate defense mechanisms  Microbial translocation correlates with chronic immune hyperactivation  Maintaining a healthy GALT may be key to reducing pathogenic potential of HIV due to compromised flora and subsequent barrier disruption resulting in elevation in inflammation 12

13 13 Conclusion Intervention with therapeutic probiotics HIV\AIDS  of drug absorption and  drug resistance  compliance to HAART  diarrhea and GI side-effects and other SAEs

14 Protocol synopsis 14 X HIV-infected patients X on ART + Imodium + Placebo X on ART + Imodium + Bio-K+ ® Outcomes  diarrhea and SAEs  OIs Stabilization of CD4 Suppression of viral load Improvements of micronutrients level  adherence and persistence to HAART DEXA + BIA Inclusion Confirmed HIV infection HIV-related anemia PCP, thrush, vaginosis, vaginitis Anal dysplasia Hairy leucopenia
