Brief Summary
Osteoporosis has a devastating impact on quality of life of postmenopausal women, and is a significant cause of disability and morbidity. Many drugs are approved for the prevention and treatment of osteoporosis, but are associated with high costs and side effects. Some data from animal studies suggests that supplementation with probiotics can safely treat and prevent osteoporosis. The probiotic VSL#3 is commercially available, is safe for human consumption, and has been widely used in human clinical trials, and has known health-promoting effects in both children and adults. The double-blind, randomized, placebo-controlled trial of VSL#3 will be conducted for 12 months in 40 postmenopausal women to determine if VSL#3 improves bone mineral density and related bone markers. Study visits will include all or some of the following procedures: a medical exam, urine collection, height and weight measurement, a blood draw to assess bone biomarkers, a DEXA (dual energy X-ray absorptiometry) scan to measure bone density, and health questionnaires. This is one of the first clinical trials proposed to investigate the effects of probiotics in bone in humans. If successful, this proposal will provide the first evidence that nutritional supplementation with the probiotic VSL#3 is a safe and effective strategy for preventing postmenopausal bone loss.

Outcome Measures
Primary Outcomes (1)
Change in Bone Mineral Density (BMD) of the Lumbar Spine (L1-L4 Segment) as Measured by Dual Energy X-ray Absorptiometry (DEXA)
All DEXA scans will be performed on the same device using a GE Lunar iDEXA machine. Participants will be asked to lie still on a scanning table with their arms at their sides for approximately 10 minutes.
Baseline and 12-month visit.
Secondary Outcomes (10)
Change in Bone Density of the Non-dominant Hip (Femoral Neck and Total Hip Area) as Measured by DEXA (Dual Energy X-ray Absorptiometry).
Baseline and 12-month visit.
Change in Serum Collagen Type 1 Cross-linked C-telopeptide (CTX) Concentrations (a Marker of Bone Resorption).
Baseline, 6-month, 12-month visits
Change in Serum Procollagen Type I N Propeptide (PINP) - a Marker of Bone Formation - Concentrations.
Baseline, 6-month, 12-month visits
Change in Serum Free Receptor Activator of Nuclear Factor Kappa-B Ligand (RANKL) Concentrations.
Baseline, 6-month, 12-month visits
Change in Serum Osteoprotegrin (OPG) Concentrations.
Baseline, 6-month, 12-month visits
- +5 more secondary outcomes

- Masking Details
- Only the Emory Investigational Drug Service (IDS) pharmacy will know which dose of probiotic was given to the subject. The study team, parents, subjects, individuals entering the data, statistician, individuals performing laboratory tests and DEXA scans, research center nurses and investigators will remain blinded as to which treatment the subjects received. Each subject will be assigned a unique identifier, which will be used in the database. In addition, all lab specimens will only include the patient's unique identifier. Permuted block sizes will not be disclosed to the blinded study personnel to minimize the likelihood of their being able to predict the next randomization assignment in the series. Investigators and all study personnel will remain blinded until the final subject has completed her final visit and primary and secondary endpoints have been analyzed.
