Short-term after spinal cord injury there is a marked increase in bone turnover and bone loss, the latter associated with an increase in Dkk-1 serum levels. The persistence of increased levels of this Wnt antagonist throughout the study and their relationship with the magnitude of bone loss suggests a contributory role of this mediator in this process.

In conclusion, administration of oral and intravenous bisphosphonates was associated with increased bone mineral density at the lumbar spine and total hip over two years in HIV-positive patients. However, none of the included trials were long enough to detect the impact of bisphosphonates on a clinically important outcome such as fracture risk.

An inverse correlation between IGF-1 levels and asymmetric dimethylarginine (ADMA), an endogenous endothelial nitric oxide synthase inhibitor that impairs nitric oxide production and secretion promoting endothelial dysfunction, was found. No significant association was found between IGF-1 and IGFBP-3 levels with angiopoietin-2, osteopontin, disease activity, systemic inflammation, metabolic syndrome features, or adipokines.
