Influence of Serum Sodium Levels on Bone Metabolism and Turnover in Hospitalized Patients (BONA)
March 1, 2024 updated by: University Hospital, Basel, Switzerland
Influence of Serum Sodium Levels on Bone Metabolism and Turnover in Hospitalized Patients - A Prospective Study (BONA-Trial)
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.
