Long-Term Effects of Severe Burn Injury on Bone Turnover and Microarchitecture.
Severe burn injury triggers massive alterations in stress hormone levels with a dose-dependent hypermetabolic status including increased bone resorption. This study evaluated bone microarchitecture measured by noninvasive high-resolution peripheral quantitative computed tomography (HR-pQCT). Changes of serum bone turnover markers (BTM) as well as regulators of bone signaling pathways involved in skeletal health were assessed. ⋯ In adult male patients, early and sustained changes of markers of bone resorption, formation and regulators of bone signaling pathways, prolonged inflammatory cytokine activities in conjunction with muscle catabolism, and vitamin D insufficiency were observed. These alterations are directly linked to a prolonged deterioration of bone microstructure. The probably increased risk of fragility fractures should be of clinical concern and subject to future interventional studies with bone-protective agents. © 2017 American Society for Bone and Mineral Research.
