The copeptin cutoff level of 4.9 pmol per liter (prespecified) is indicated in red, and the cutoff of 6.5 pmol per liter (derived post hoc) is indicated in blue. The copeptin and NT-proBNP levels for all CHF patients were 14.22 ± 6.38 pmol/L and 1026.55 ± 311.38 ng/L, respectively (Fig. (Fig.1A, 1 A, B). The copeptin and NT-proBNP levels for the healthy candidates in the control group were 5.29 ± 1.05 pmol/L and 345.15 ± 92.35 ng/L, respectively (Fig. (Fig.1A, 1 A, B). Both the copeptin and NT-proBNP values were significantly higher in the patients with CHF than in the healthy candidates. In multivariate logistic regression analysis, plasma copeptin level emerged as an independent predictor of progressive hemorrhagic injury and acute traumatic coagulopathy. Using receiver operating characteristic curves, we calculated areas under the curve for progressive hemorrhagic injury and acute traumatic coagulopathy. Copeptin plasma levels in healthy adults range from 1 to 13 pmol/L and are very sensitive to osmotic and hemodynamic stimuli similarly to AVP [48, 63, 67].

Elevated plasma copeptin levels are associated with higher risk of insulin resistance-related disorders, such as type 2 diabetes (T2DM), metabolic syndrome (MS), and cardiovascular disease, and experimental reduction of circulating VP copeptin levels, as validated surrogate for plasma vasopressin levels, are associated with ADPKD disease severity12 and progression13–15 in single-center studies that were often of Correspondence: Ron T. Gansevoort, Department of Nephrology, University Medical Center Groningen, P.O. Box 30.001, 9700 RB Groningen, Netherlands. 2016-03-08 · Copeptin levels were significantly higher after the first day of Percutaneous transluminal coronary angioplasty and stent treatment. After the third and fifth days of the treatment, copeptin was still high in the treated group compared to the control group, although these levels did decrease [ 15 ]. The copeptin levels of the control group were 0.34 (0.25–0.42) ng/mL and were significantly lower than those of the patient group (P < 0.000). According to our results, 0.345 ng/mL for plasma copeptin level as the best cut-off level may be used with sensitivity 2010-05-26 · Copeptin levels have also been found to be elevated in ischemic stroke patients; in this group of patients, high copeptin levels were highly predictive for poor functional outcome and mortality. We tested the hypothesis that high copeptin levels in acute hemorrhagic stroke patients are also associated with mortality and poor functional outcome.

Copeptin, a marker of vasopressin, in abdominal obesity

It is a reliable surrogate marker for arginine vasopressin (AVP). In contrast, for the difficult differentiation between central diabetes insipidus and primary polydipsia, a stimulated copeptin level of 4.9 pmol/L upon hypertonic saline infusion differentiates these two entities with a high diagnostic accuracy and is clearly superior to the classical water deprivation test. § In a secondary analysis, a copeptin level of more than 6.5 pmol per liter indicated primary polydipsia, and a level of 6.5 pmol or less per liter indicated complete or partial central diabetes Elevated plasma copeptin levels identify the presence and severity of non-alcoholic fatty liver disease in obesity. Forskningsoutput: Tidskriftsbidrag › Artikel i vetenskaplig tidskrift 7.7.5.3.2 Copeptin levels Copeptin has been investigated as a surrogate marker of AVP, the C-terminal end of the AVP prohormone called copeptin, as it may be more stable than ADH and may give better separation of the diagnostic groups. Copeptin levels increased with increasing severity of CAP, as classified by the pneumonia severity index (PSI) (P < 0·001). In patients who died, copeptin levels on admission were significantly higher as compared to levels in survivors [70·0 (28·8–149·0) vs. 24·3 (10·8–43·8) pmol L −1, P < 0·001].
