Copeptin levels were significantly higher in the OSAS group compared to the control group (146 [93-739] pg/ml vs. 111 [33-253] pg/ml, respectively, p < 0.001).

Unlike AVP, copeptin is stable in plasma. Both copeptin and AVP are responsive to osmotic stimuli and increase in response to water deprivation. In healthy subjects, water deprivation causes the plasma osmolality to rise above approximately 280-290 mOsmol/kg, leading to the release of AVP and copeptin into the circulation. Baseline characteristics of the 1280 ADPKD patients included in this study are shown in Table 1, stratified according to sex-adjusted quartiles of baseline plasma copeptin level.

It is characterized by increased blood pressure, proteinuria, increased peripheral vascular resistance and reduced organ perfusion. 1 Incidence of Copeptin is a stable by-product of arginine-vasopressin synthesis and reflects its secretion. The objective of the study was to evaluate the predictive value of copeptine on functional outcome at 90-day follow-up from stroke onset. We conducted a prospective, observational cohort study in the emergency department of two hospitals and enrolled 125 patients with acute ischemic stroke.

The aim of this study was to investigate the plasma copeptin level for childhood migraine headache. 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 RESEARCH ARTICLE Open Access Serum Copeptin levels in the emergency department predict major clinical outcomes in adult trauma patients Fulvio Salvo1,2*, Francesco Luppi1, Davide M.

Conclusions: Plasma copeptin levels predict mortality in outpatients with chronic heart failure independently from clinical variables, plasma sodium, and loop

2019-04-30 · Introduction. Copeptin is the stable surrogate marker of vasopressin (VP), which is released in response to elevated plasma osmolality or low blood pressure. 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, Copeptin levels were significantly different between tolvaptan- and placebo-treated subjects during treatment (all time points P < 0.0001). After withdrawal of both treatments, copeptin in previously tolvaptan-treated subjects decreased to 6.3 pmol/l, whereas in placebo-treated subjects it remained stable (7.0 pmol/l, difference with previously tolvaptan-treated subjects P = 0.07).

In the present study, the median copeptin level was 8.6-9.1 pmol/l in non-diabetic individuals, which is comparable to levels described in other population-based studies (ranging from 5.0 pmol/l to 8.2 pmol/l [4,6,7,41]), but 2-10-fold lower than reported in studies investigating severe disorders, such as stroke, myocardial infarction or end stage kidney disease [9,14,42]. In a described algorithm(1), patients with a copeptin concentrations of under 21.4 pmol/L and a copeptin cut-off of 4.9 pmol/L after fluid deprivation, was used to distinguish between complete or partial DI (<4.9 pmol/L) and primary polydipsia (> or =4.9 pmol/L). We measured copeptin levels of 86 patients on days 1, 3, 5, 7, 9, 11, and 13 using ELISA. The primary outcome was the association between consecutive copeptin levels and DCI development.

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).
