- Abstract
Background. The new polypeptide hormones adropin and irisin have a broad impact on human metabolism and energy homeostasis. They could be potential biomarkers of cardiac injury. In end-stage renal disease (ESRD), the clinical importance of adropin and irisin is yet to be investigated. Objectives. The aim of this study was to determine the relationship between these peptides and cardiac status in ESRD patients. Material and methods. Seventy-nine ESRD patients on hemodialysis (HD), peritoneal dialysis (PD) or after renal transplantation (Tx), and 40 healthy, age- and sex-matched controls (CON) were included in this study. Serum concentrations of adropin and irisin were measured with enzyme-linked immunosorbent assay (ELISA). Cardiac status was estimated by transthoracic echocardiography and the plasma concentration of N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin T (cTnT). Results. The levels of irisin were significantly lower in HD patients as compared to CON. During HD sessions, the concentrations of adropin did not change significantly, whereas the concentrations of irisin increased with borderline significance. Positive correlations were evident between adropin concentration and cTnT as well as NT-proBNP. Adropin was also correlated with left ventricular systolic internal diameter (LVIDs) (r = 0.375, p = 0.045) and relative wall thickness (RWT) (r = -0.382, p = 0.034). Irisin was correlated with right ventricular diameter (RVd) (r = -0.363, p = 0.045). No correlations were found between irisin and adropin, and blood pressure (BP) measurements. Conclusions. Adropin could be a new candidate marker of cardiac dysfunction in HD patients. The cause of low levels of irisin found in HD patients is still unclear. These 2 myokines should be further investigated as potential prognostic markers of cardiac status in HD patients.
