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

21 Dec 2015 Diabetes insipidus (DI) is a hereditary or acquired condition which disrupts NPII, and glycopeptides copeptin and is released as AVP from neurons in the desmopressin challenge test in the diagnosis of diabetes insi

Arginine-stimulated copeptin measurements in the differential diagnosis of diabetes insipidus: a prospective diagnostic study. Lancet 2019;394:587-95. A single Copeptin measurement can immediately distinguish central diabetes insipidus from nephrogenic diabetes insipidus. As a consequence, Copeptin measurement reduces the burden of the water deprivation test for the majority of patients and improves patient management within the clinic. Ref-1. Smart Copeptin testing. Reliable results Plasma Copeptin More Accurate for Diabetes Insipidus Diagnosis Aug 6, 2018 MONDAY, Aug. 6, 2018 (HealthDay News) — In patients with hypotonic polyuria, the direct measurement of hypertonic saline-stimulated plasma copeptin has better diagnostic accuracy than the water-deprivation test, according to a study published in the Aug. 2 issue of the New England Journal of Medicine .

Authors of this article are: Winzeler B, Cesana-Nigro N, Refardt J, Vogt DR, Imber C, Morin B, Popovic M, Steinmetz M Copeptin is a stable glycoprotein product of preprovasopressin which, in contrast to AVP, is measured readily and robustly. When measured during a WDT, copeptin levels have diagnostic accuracy in 94% of patients. This novel test for better differentiation of PPS requires prospective evaluation. 2018-11-01 · 1.

Baseline copeptin levels, without prior thirsting, unequivocally identify patients with nephrogenic diabetes insipidus. 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. Background: The differential diagnosis of diabetes insipidus is challenging.

This study shows that arginine is a potent stimulus of the posterior pituitary gland and that arginine-stimulated copeptin measurements are an accurate test for diabetes insipidus. We found that a copeptin cutoff of 3·8 pM/L at 60 min after arginine infusion had an accuracy of 93% to diagnose diabetes insipidus in a dataset of patients with diabetes insipidus and primary polydipsia.

Using the measured lab value, we will access the optimal cut point value of copeptin which predicts development of central diabetes insipidus postoperatively with highest accuracy.

Bakgrund Copeptin eller CT-proAVP är en glykopeptid på 39 aa som kommer från samma precursor som vasopressin A baseline Copeptin level >21.4 pmol/L is 100% sensitive and specific for nephrogenic diabetes insipidus A baseline Copeptin level < 2.6 pmol/L with prior fluid deprivation (> 8hrs) will indicate complete central DI likely Although the water deprivation test determined the correct diagnosis with 76.6% accuracy, the copeptin test had a 97% rate of correct diagnoses.

We hypothesized that arginine-stimulated copeptin measurements provide an alternative, simple and safe diagnostic test for diabetes insipidus. 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).

Furthermore, the role of copeptin as a predictive marker for the development of diabetes insipidus following surgical procedures in the sellar region is described. Copeptin measurement has led to a “revival” of the direct test in the differential diagnosis of diabetes insipidus.
