Associations of Common Variants in HFE and TMPRSS6 Genes with Hepcidin-25 and Iron Status Parameters in Patients with End-Stage Renal Disease
BACKGROUND: Influence of TMPRSS6 A736V and HFE (C282Y and H63D) polymorphisms on serum hepcidin-25 levels and iron status parameters in end-stage renal disease (ESRD) patients stratified according to gender has not been previously investigated. In addition, we aimed to evaluate the diagnostic accura...

Sumario: | BACKGROUND: Influence of TMPRSS6 A736V and HFE (C282Y and H63D) polymorphisms on serum hepcidin-25 levels and iron status parameters in end-stage renal disease (ESRD) patients stratified according to gender has not been previously investigated. In addition, we aimed to evaluate the diagnostic accuracy of the parameters to separate iron-deficiency anemia (IDA) from anemia of chronic disease. MATERIALS AND METHODS: Iron status parameters and genetic analysis were performed in 126 ESRD patients and in 31 IDA patients as the control group. RESULTS: ESRD patients had significantly higher ferritin and hepcidin-25 (<0.001) relative to IDA patients. Cut-off values with the best diagnostic accuracy were found for hepcidin ≥9.32 ng/mL, ferritin ≥48.2 μg/L, transferrin saturation ≥16.8%, and MCV ≥81 fL. Interaction between gender and HFE haplotypes for the hepcidin-25 and ferritin levels in ESRD patients (p = 0.005, partial eta squared = 0.09; p = 0.027, partial eta squared = 0.06, respectively) was found. Serum transferrin was influenced by the combined effect of gender and TMPRSS6 A736V polymorphism in ESRD patients (p = 0.002, partial eta squared = 0.07). CONCLUSION: Our findings could contribute to the further investigation of mechanisms involved in the pathophysiology and important gender-related involvement of the TMPRSS6 and HFE polymorphisms on anemia in ESRD patients. |
