Severe burn injury causes a massive and prolonged stress response.
This study investigated early and prolonged changes of serum bone turnover markers (BTM) and regulators of bone metabolism. Thirty two male patients with a median age of 40.5 years and a median burned total body surface area (TBSA) of 40% were included.

During the early phase pronounced increases were observed for CTX, P1NP, sclerostin, DKK-1, BALP, FGF23 and iPTH levels, whereas 25-OH vitamin D, albumin, serum and ionized calcium levels decreased.

In the prolonged phase (day 21 – 56), changes of P1NP were most pronounced, followed by elevated sclerostin, OCN, BALP, and lesser changes for albumin levels. In contrast levels of iPTH, FGF23, CRP and to a lesser extent CTX and phosphate levels, declined significantly during this phase of investigation.

Ongoing changes of BTM and regulators of bone metabolism suggest alterations in bone metabolism with a likely adverse influence on bone quality and structure in male patients with severe burn injuries.
