Synthetic V2 receptor agonist (dDAVP) reduced significantly calcium fractional excretion from 1.71% to 0.58% (PÂ <Â 0.05) in patients with central diabetes insipidus. We analyzed calcium, potassium, and sodium fractional excretion in eight patients affected by insipidus diabetes (nephrogenic or central) under acute vasopressin receptor agonist action and in 10 patients undergoing oral water load test affected or not by inappropriate antidiuretic hormone secretion (SIADH). The objective of this study was to assess whether AVP modulates renal calcium excretion in humans. Three decades ago, experimental models have shown that AVP may increase calcium reabsorption in rat kidney.
