Copeptin and the Diagnosis of Diabetes Insipidus This study compared the indirect water-deprivation test with direct detection of plasma copeptin, a precursor of arginine vasopressin, in patients A Copeptin-Based Approach in the Diagnosis of Diabetes Insipidus. The direct measurement of hypertonic saline-stimulated plasma copeptin had greater diagnostic accuracy than the water-deprivation test in patients with hypotonic polyuria.

Methods: We recruited a development cohort (cohort 1, N =52) and a validation cohort (cohort 2, N =44) including patients with central diabetes insipidus (total N =38) and with primary polydipsia (total N =58). In patients undergoing pituitary surgery, copeptin levels represent a novel marker for postoperative diabetes insipidus, according to data published in the Journal of Clinical Endocrinology & Metabolism. “Central diabetes insipidus is observed in 16% to 34% of … 2018-06-04 The test protocols of the two tests are provided and a new copeptin-based diagnostic algorithm is proposed to reliably differentiate between the different entities. Furthermore, the role of copeptin as a predictive marker for the development of diabetes insipidus following surgical procedures in the sellar region is described.

2,6 - 20 pmol/l: further Investigation needed (further information fig 3.) > 20 pmol/l: Nephrogenic diabetes insipidus Bettina Winzeler, Christian Zweifel, Nicole Nigro, Birsen Arici, Martina Bally, Philipp Schuetz, Claudine Angela Blum, Christopher Kelly, Sven Berkmann, Andreas Huber, Fred Gentili, Gelareh Zadeh, Hans Landolt, Luigi Mariani, Beat Müller, Mirjam Christ-Crain, Postoperative Copeptin Concentration Predicts Diabetes Insipidus After Pituitary Surgery, The Journal of Clinical Endocrinology Copeptin levels of less than 2.5 pmol/L reliably identified diabetes insipidus after pituitary surgery, while levels of more than 30 pmol/L ruled out the condition, investigators reported online in the Journal of Clinical Endocrinology and Metabolism.

Copeptin is secreted in an equimolar amount to arginine vasopressin (AVP) but can easily be measured in plasma or serum with a sandwich immunoassay. Copeptin and the Diagnosis of Diabetes Insipidus This study compared the indirect water-deprivation test with direct detection of plasma copeptin, a precursor of arginine vasopressin, in patients Interpretation: Arginine-stimulated copeptin measurements are an innovative test for diabetes insipidus with high diagnostic accuracy, and could be a simplified, novel, and safe diagnostic approach to diabetes insipidus in clinical practice.

A nonwater deprived baseline copeptin concentration of 21.4 pmol/L or greater was found to be consistent with the presence of nephrogenic diabetes insipidus (DI). A first proof‐of‐concept study in 2007 used the classical insulin tolerance test and showed that copeptin measured during hypoglycaemia is a useful measure to identify patients with complete central diabetes insipidus at 3 months after transsphenoidal pituitary surgery. 56 In this study, copeptin levels of patients with intact posterior pituitary showed a maximal increase to 11.1 ± 4.6 pmol/L, while copeptin levels in patients with central diabetes insipidus remained low upon Background: The differential diagnosis of diabetes insipidus is challenging. The most reliable diagnostic approach is hypertonic saline-stimulated copeptin measurements. However, as this test is based on the induction of hypernatremia, it is associated with adverse effects and needs close sodium monitoring.
