dc.description.abstractAimThis study aimed to compare plasma copeptin levels, the c-terminal of provasopressin, between individuals with bipolar disorder (BD) and healthy controls and to assess the relation between copeptin and metabolic parameters. MethodsWe measured plasma levels of copeptin in individuals with BD (n=55) and healthy controls (n=21). Information related to psychiatric/medical history, as well as to metabolic comorbidities and laboratorial parameters was also captured. Insulin resistance and -cell function in basal state were calculated from fasting plasma glucose and C-peptide using the HOMA2 calculator. Impaired glucose metabolism was defined as pre-diabetes or type 2 diabetes mellitus. Copeptin, adiponectin, and leptin plasma levels were determined by enzyme-linked immunosorbent assay. ResultsPlasma copeptin levels were lower in individuals with BD, relative to healthy controls (P<0.001). There were significant interactions between BD and plasma copeptin on -cell function (rate ratio [RR]=1.048en
dc.description.abstractP=0.030) and on leptin levels (RR=1.087en
dc.description.abstractP=0.012), indicating that there was a positive correlation between these markers in the BD group, but a negative one in healthy controls. Finally, in individuals with BD only, the association between -cell function, body mass index (RR=1.007en
dc.description.abstractP<0.001), and insulin resistance (RR=1.001en
dc.description.abstractP=0.037) was moderated by copeptin levels. ConclusionCopeptin levels were lower in individuals with BD than in healthy controls. There were differential associations between copeptin and metabolic parameters within the BD and healthy control subgroups, suggesting an association between abnormal copeptin and metabolic dysregulation only in the BD population.en
