lthough inflammation can arise from infection or injury, chronic inflammation can occur in older age due to ageing processes in the immune system. Higher levels of inflammation in older age has been linked to lower bone density, according to a new study carried out at the University of Southampton.
Scientists from the University’s Medical Research Council Lifecourse Epidemiology Unit (MRC LEU) examined the relationship between levels of inflammation in early old age and bone density at the spine and the hip. The relationship between levels of inflammation and change in bone density over the next 5 years was also explored.
The study, published in Osteoporosis International, showed that higher levels of adiponectin was related to lower bone density at the spine and hip, and lower levels of interleukin-10 (IL-10) was associated with faster decline in bone density at the spine. Adiponectin and IL-10 each modify the pro- and anti-inflammatory balance.
Lead author, Nicholas Fuggle, researcher at the University of Southampton, said “Low bone density increases the risk of osteoporosis which affects so many older people and is extremely debilitating. This study highlights the importance of inflammatory markers in the development of osteoporosis. We hope that this study will help us develop potential ways of combatting the condition which will lead to improvements in quality of life.”
