Abstract

Anemia is one of the most common problems in chronic kidney disease (CKD). In several cases, despite comprehensive investigations, definite causes of anemia frequently remain unknown. We aimed to analyze the factors that possibly affect anemia in CKD patients who were referred for hematology consultation. A total of 87 patients were retrospectively included in the cohort. Forty-four cases were excluded, 30 cases with unavailable intact parathyroid hormone (iPTH) data, 11 cases with bone marrow diseases (8 Pure red cell aplasia, 3 Myelodysplastic syndrome) and 3 cases with thalassemia. Totally, 43 patients were analyzed. Patients with high iPTH had significantly lower Hemoglobin (Hb) level and required higher dose of erythropoietin stimulating agents (ESAs) compared with normal iPTH group (Hb 8.29 vs. 9.24 mg/dL, p = 0.032 and ESAs dose of 16,352.94 vs. 12,444.44 U/ week, p = 0.024). In univariate followed by stepwise multivariate analysis, serum phosphate (PO4) was significantly associated with lower Hb level (p = 0.01 and p = 0.013, respectively). Hb level was inversely correlated with iPTH and PO4 level (r = −0.54, p < 0.001 and r = −0.47, p = 0.05; respectively). Mineral disequilibrium is an important factor associated with anemia in ESA hyporesponsive CKD. Hyperphosphatemia and secondary hyperparathyroidism are significantly correlated with low Hb. Therefore, we strongly suggest correction of these mineral disequilibrium factors prior to performing bone marrow study.
