| Outline of Final Research Achievements |
Renal anemia in chronic kidney disease (CKD) is caused by deficiency of erythropoietin (EPO) accompanied by renal fibrosis and refractory disease state to EPO. In this study, we used a cohort study and metabolomic analysis to identify patients patients requiring active intervention for renal anemia. Using CKD cohort, it revealed that anemia less than Hb 10 g / dL leads to end-stage renal failure or cerebrovascular disease and all-cause of deaths in each CKD stage. We also found that malnutrition is associated with anemia especially in wasting patients such as elderly over 75 years and in patients with serum albumin levels <4 g / dl. In addition, it was suggested that nutritional index and anemia are related in patients with induction renal failure. Among the protein-bound uremic substances in the serum of patients with renal failure, we found associations between sarcopenia and glycation end products (AGEs) formation process, and could be resistant to EPO.
