Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the possible role of serum sodium concentration and its changes on bone markers in hospitalized, hyponatremic patients is determined. Therefore, it is investigated whether in hospitalized, hyponatremic patients the level of carboxy-terminal collagen crosslinks (CTX) is modified by changes in plasma sodium concentration, independently from the aetiology of hyponatremia.
