AIM: To assess the correlation between the serum hepcidin-25 level and left ventricular mass index. METHODS: This study was a cross-sectional study conducted between March 2009 and April 2010. Demographic and biochemical data, including the serum hepcidin-25 level, were collected for chronic kidney disease (CKD) patients. Two-dimensional echocardiography was performed to determine the left ventricle mass (LVM), left ventricular mass index (LVMI), interventricular septum thickness (IVSd), left ventricle posterior wall thickness (LVPW), right ventricular dimension (RVD), left atrium (LA) and ejection fraction (EF). RESULTS: A total of 146 patients with stage 1 to 5 CKD were enrolled. Serum hepcidin-25 levels were 16.51 ± 5.2, 17.59 ± 5.32, 17.38 ± 6.47, 19.98 ± 4.98 and 22.03 ± 4.8 ng/mL for stage 1 to 5 CKD patients, respectively. Hepcidin-25 level was independently predicted by the serum ferritin level (β = 0.6, P = 0.002) and the estimated glomerular filtration rate (β = -0.48, P = 0.04). There were negative correlations between the serum hepcidin level and the LVM and LVMI (P = 0.04 and P = 0.005, respectively). Systolic blood pressure (BP) was positively correlated with the LVMI (P = 0.005). In the multivariate analysis, a decreased serum hepcidin-25 level was independently associated with a higher LVMI (β = -0.28, 95%CI: -0.48 - -0.02, P = 0.006) after adjusting for body mass index, age and systolic BP. CONCLUSION: A lower serum hepcidin level is associated with a higher LVMI in CKD patients. Low hepcidin levels may be independently correlated with unfavorable cardiovascular outcomes in this population.
