This retrospective observational study will assess the incidence of hemoglobin cycling in chronic kidney disease (stage 3, 4, and 5) patients with renal anemia treated with Mircera (methoxy polyethylene glycol-epoetin beta). Data will be collected from each patient from a 9-month treatment period.


Study Type: Observational
Study Design: Observational Model: Cohort

Primary Outcome Measures:
  • Proportion of patients with hemoglobin cycling (oscillation in hemoglobin of >/= 1.5 g/dL over 8 weeks) [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Within patient frequency of full hemoglobin cycles (oscillation in hemoglobin of >/= 1.5 g/dL over 8 weeks) [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Incidence of hemoglobin cycling according to baseline demographic and clinical characteristics (age, gender, cause of renal disease, diabetes, dialysis or predialysis status) [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Proportion of patients with diabetes type II who experienced hemoglobin cycling within the 9 months observation period [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Incidence of hemoglobin cycling according to baseline demographic and clinical characteristics (age, gender, cause of renal disease, diabetes, dialysis or predialysis status) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
