The human microbiome has been shown to influence a number of chronic conditions
associated with impaired bone mass and bone quality, including obesity, diabetes,
and inflammatory bowel disease. The connection between the microbiome and bone
health, however, has not been well studied. The few studies available demonstrate
that the microbiome can have a large effect on bone remodeling and bone mass. The
gut microbiome is the largest reservoir of microbial organisms in the body and
consists of more than a thousand different species interacting with one another
in a stable, dynamic equilibrium. How the microbiome can affect organs distant
from the gut is not well understood but is believed to occur through regulation
of nutrition, regulation of the immune system, and/or translocation of bacterial
products across the gut endothelial barrier. Here we review each of these
mechanisms and discuss their potential effect on bone remodeling and bone mass.
We discuss how preclinical studies of bone-microbiome interactions are
challenging because the microbiome is sensitive to genetic background, housing
environment, and vendor source. Additionally, although the microbiome exhibits a
robust response to external stimuli, it rapidly returns to its original steady
state after a disturbance, making it difficult to sustain controlled changes in
the microbiome over time periods required to detect alterations in bone
remodeling, mass, or structure. Despite these challenges, an understanding of the
mechanisms by which the gut microbiome affects bone has the potential to provide
insights into the dissociation between fracture risk and bone mineral density in
patients including those with obesity, diabetes, or inflammatory bowel disease.
In addition, alteration of the gut microbiome has the potential to serve as a
biomarker of bone metabolic activity as well as a target for therapies to improve
bone structure and quality using pharmaceutical agents or pre- or probiotics. ©
