N Engl J Med 2018;379:428-439DOI: 10.1056/NEJMoa1803760 Rosen CJ, and Ingelfinger JR. Whereas unstimulated basal copeptin measurement reliably diagnoses nephrogenic diabetes insipidus, two new tests using stimulated copeptin cutoff levels showed a high diagnostic accuracy in Copeptin - The Copeptin test is used in the diagnosis of central diabetes insipidus and in the differential diagnosis of central or nephrogenic diabetes insipidus. It is a reliable surrogate marker for arginine vasopressin (AVP). 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.

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 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. Copeptin measurement has led to a “revival” of the direct test in the differential diagnosis of diabetes insipidus. Baseline copeptin levels, without prior thirsting, unequivocally identify patients with nephrogenic diabetes insipidus.

Baseline copeptin levels, without prior thirsting, unequivocally identify patients with nephrogenic diabetes insipidus. Copeptin measurement has led to a “revival” of the direct test in the differential diagnosis of diabetes insipidus. 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.

2018-08-16 · A hypertonic saline–stimulated plasma copeptin level lower than 6.5 pmol/L was 95% sensitive and 100% specific for central diabetes insipidus. This test's accuracy was superior to that of water-deprivation testing (with or without measurement of copeptin), and it distinguished between primary polydipsia and both partial and complete central diabetes insipidus. Primary polydipsia was distinguished from partial central diabetes insipidus with the indirect water-deprivation test in 77 of 105 patients (73.3 percent), compared to 99 of 104 patients (95.2 percent) with the hypertonic saline infusion. Further, 22 of 27 patients with diabetes insipidus had copeptin levels lower than 2.5 pmol/L, yielding a positive predictive value of 81% and a specificity of 97%. In contrast, only one patient of 40 with copeptin levels greater than 30 pmol/L had diabetes insipidus on day 1 after surgery (negative predictive value, 95%; sensitivity, 94%).
