    This study evaluates bone metabolism in patients with arginine vasopressin deficiency (AVP-D) compared to primary polydipsia (PP) and healthy controls (HC).

  • 2

    Patients with AVP-D exhibited lower levels of bone resorption marker CTX compared to healthy controls, indicating potential differences in bone metabolism.

  • 3

    The bone formation index was higher in AVP-D patients than in healthy controls, suggesting altered bone turnover despite lower CTX levels.

  • 4

    Serum 25OH-vitamin D concentrations were significantly lower in AVP-D patients compared to healthy controls, highlighting a potential deficiency.

  • 5

    Overall findings suggest that AVP-D does not lead to major detrimental alterations in bone metabolism compared to healthy individuals.
