The Effect of Lactobacillus Reuteri ATCC PTA 6475 on Volumetric Bone

Status Completed

Clinical Trial Summary

Lactobacillus reuteri (L. reuteri) has been widely studied in clinical trials and has probiotic, health-promoting effects in both adults and children, and is safe for human consumption. Animal models indicate that treatment with L. reuteri has positive effects on bone metabolism and bone density. In other animal models of diabetes and the metabolic syndrome, positive effects on blood glucose and weight have been reported. The present double-blind, placebo-controlled, randomized study is designed to investigate if dietary supplementation with L. reuteri twice daily for 12 months has any effect on bone density, body composition, inflammation, or metabolic and endocrine markers in elderly women with osteopenia.

Clinical Trial Description

The role of the gut microbes for human health has gained considerable interest in recent years. Lactobacillus reuteri (L.reuteri) is a naturally occurring bacterial species in the human gut. L. reuteri has been widely studied in clinical trials of adults and children and treatment with L. reuteri is safe and is associated with health-promoting effects in humans. In animal models, L. reuteri has anti-inflammatory effects and in ovariectomized mice supplementation with L. reuteri partly prevented the bone loss induced by estrogen deficiency. Furthermore, both bone density and bone formation increased in male mice in another mice model. In mice with medically induced diabetes mellitus, L. reuteri reduced blood glucose and in a mouse model mimicking the metabolic syndrome, L. reuteri prevented diet-induced obesity. The present study is a double-blind, placebo-controlled, randomized, study in 90 elderly women with osteopenia recruited from the population. These women will be treated with L. reuteri or placebo orally twice daily for 12 months. The effects on bone will be investigated with dual energy x-ray absorptiometry, high-resolution peripheral quantitative computed tomography, and bone turnover markers. Hormones and markers of inflammation and metabolism will be followed as well as changes in the gut microbiota composition. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
