Abstract

This study aimed to explore the relationship between recombinant human erythropoietin (EPO) responsiveness, insulin resistance, and malnutrition-inflammation-atherosclerosis (MIA) syndrome in hemodialysis patients. This was an observational cohort study in hemodialysis patients. Adipokines, inflammatory cytokines, and required EPO dosage were measured in diabetes (DM; n=58) and non-diabetes (non-DM; n=58) groups over 48 weeks. Furthermore, the EPO responsiveness index (required EPO dosage divided by hemoglobin) was evaluated with or without MIA syndrome in both groups. The DM group had significantly higher plasma leptin, interleukin-6 (IL-6), and high sensitivity C-reactive protein (hs-CRP) levels but lower plasma high molecular weight (HMW) adiponectin levels compared to the non-DM group. Although hemoglobin levels were not significantly different, required EPO dosage was significantly higher in the DM group than in the non-DM group, particularly in the presence of MIA syndrome. The DM group with MIA syndrome had significantly higher plasma leptin, IL-6, and hs-CRP levels but lower plasma HMW adiponectin levels compared to the non-DM group with MIA syndrome. There was also a significant association between EPO dosage and homeostasis model assessment for insulin resistance (HOMA-IR), hs-CRP, IL-6, tumor necrosis factor a, leptin, and HMW adiponectin levels in DM patients with MIA syndrome. Diabetic hemodialysis patients with MIA syndrome have a lower response to EPO and a higher resistance to insulin. This fact may explain the poor outcome of these patients and demonstrate the importance of diagnosis and therapeutic management.
