Anaemia is an important issue in patients undergoing haemodialysis. We aimed to identify a better dosing schedule of a fixed monthly dose of continuous erythropoietin receptor activator (CERA) in patients with chronic kidney disease (CKD) on haemodialysis. The CERA dosing schedule included 100 μg once monthly for 2 months, 50 μg twice monthly for 2 months and then 100 μg once monthly for two months. The effectiveness was determined by comparing haematocrit, nutritional status (serum protein and albumin) and inflammatory markers (tumour necrosis factor (TNF)-α, interleukin (IL)-1, IL-6 and Hepcidin) at the beginning of the study with those at the end of the study. Forty-seven out of 67 patients completed the trial. At the end, haematocrit was significantly higher (34.51 vs 33.22%, P=.004), levels of inflammatory markers were significantly lower (TNF-α (30.71 vs 35.67 ng/mL, P=.007), IL-6 (5.12 vs 7.95 ng/mL, P=.033), hepcidin (60.39 vs 74.39 ng/mL, P=.002)), blood glucose levels were significantly lower (112.40 vs 139.02 mg/dL, P=.003) and albumin was significantly higher (4.11 vs 3.98, P=.001). Patients with a better than average response had a lower initial number of red blood cells (3.3 vs 3.6 × 106/mm3, P=.025) and a lower IL-1 (3.8 vs 12.9 ng/mL, P=.01). They also had significantly lower blood glucose levels at the end. (91.3 vs 124.0 mg/dL, P=.03). We demonstrate that a fixed monthly dose of CERA at a twice monthly dosing schedule improves nutrition, reduces the inflammation and corrects anaemia in patients on haemodialysis. This finding may provide a new strategy for treating CKD-related anaemia.
