High serum copeptin may be a marker of an increased carotid intima-media thickness in asymptomatic patients with type 1 diabetes.

Abstract Copeptin is a stable peptide derived from cleavage of the precursor of arginine-vasopressin (AVP), [1,2] that can be easily measured by using a simple rapid assay. Copeptin has been related with an increased incidence of stroke and cardiovascular mortality in individuals with diabetes, mainly type 2 [3,4]. It is also a risk predictor for end-stage renal disease, coronary heart disease, and all-cause mortality in people with type 1 diabetes (T1DM) [5]. However, we have recently reported that copeptin does not appear to be a reliable marker for the screening of asymptomatic peripheral arterial disease in a population of patients with T1DM [6]. We here explore the putative relationships between serum copeptin level and carotid intima-media thickness (cIMT) in asymptomatic T1DM-patients comprehensively investigated for subclinical carotid atherosclerosis.
