Abstract:
:Hepcidin is a small defensin-like peptide whose production by hepatocytes is modulated in response to anemia, hypoxia, or inflammation. Hepcidin could also act as an indicator of functional iron deficiency in these patients. Cross-sectional study was performed to assess hepcidin correlations with renal function, iron status, and hsCRP in patients with chronic renal failure on conservative treatment, on hemodialyses, and in kidney transplant recipients. Iron status, complete blood count, creatinine, albumin, lipids were assessed using standard laboratory methods. GFR was estimated using MDRD formula. Hepcidin and high sensitivity CRP were measured using commercially available kits. Ferritin and hepcidin were higher in hemodialyzed patients, kidney transplant recipients, and patients with chronic renal failure over controls. In patients with chronic renal failure, hepcidin correlated significantly with total protein, albumin, creatinine, and eGRF. In kidney transplant recipients, hepcidin correlated significantly in univariate analysis, with total protein, ferritin, time after transplantation, creatinine, eGRF and tended to correlate with cholesterol. In hemodialyzed patients hepcidin, correlated significantly with triglycerides, albumin, creatinine, urea, residual renal function, and hsCRP. In healthy volunteers, hepcidin was related to triglycerides and ferritin. Multiple regression analysis in hemodialyzed patients showed that hepcidin was independently related to creatinine, triglycerides, and residual renal function. Multiple regression analysis in kidney transplant recipients showed that hepcidin was independently related only to GFR and ferritin. Elevated hepcidin in all groups of patients studied may be due to low grade inflammation, frequently encountered in this population and mainly to impaired renal function.
