Abstract

Background: Anemia is a factor that affects the outcome of patients with chronic kidney disease (CKD); however, there are only a few reports on the management of anemia in Japanese patients with CKD who are not on dialysis. Methods: We investigated the prevalence, related factors and management of anemia in CKD stage 3-5 patients in Japan based on the baseline data obtained from a prospective cohort study (Chronic Kidney Disease Japan Cohort). Anemia was defined as having a hemoglobin (Hb) level of <11 g/dL or receiving erythropoiesis stimulating agent (ESA) therapy. Results: The result indicated that 946 out of 2,930 patients had anemia. Of these 946 patients, 385 were receiving ESA treatment for anemia and had an Hb level of 10.28 ± 1.19 g/dL (mean ± SD). The percentage of these patients with an Hb level above the target of 11 g/dL proposed for treatment by the Japanese guidelines, and above the maintenance level of 10 g/dL approved for ESA therapy in Japan, was only 30.1 and 61.6%, respectively. In contrast, the percentage of patients receiving no ESA therapy was 67.6 and 55.7%, respectively, among those with an Hb level of <11 and <10 g/dL. Conclusions: These data suggested that prevalence of anemia was high in Japanese patients with CKD stage 3-5, that the percentage of patients receiving ESA was low among those who required ESA, and that a large number of patients receiving ESA failed to maintain the recommended level of Hb.
