LATINO Study: A Study of Mircera for the Maintenance Treatment of Dialysis Patients With Chronic Renal Anemia.

The Hb levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The mean change in the Hb concentration between the Stability Verification Period (SVP) and the EEP is reported.

The Hb levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The percentage of participants maintaining their mean Hb concentration within the target range 10.5 and 12.5 g/dL throughout the EEP are reported.

The Hb levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The mean time (days) spent by the participants in the Hb target range 10.5 to 12.5 is reported.

The Hb levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The mean C.E.R.A dose required to maintain the Hb level within the range 10.5-12.5 g/dL throughout the EEP is presented.

Dose adjustments were necessary when Hb increased or decreased by a clinically significant amount. The dose of C.E.R.A. was adjusted to maintain the individual participant's Hb within a range of +/-1.0 g/dL of the reference Hb concentration and between 10.5 and 12.5 g/dL throughout the DTP (Week 0 to Week 16) and the EEP (Weeks 16 to 24). The reference Hb value was taken as the mean of all Hb assessments during the stability verification period (Weeks -4, -3, -2, -1). The percentage of participants requiring C.E.R.A dose adjustments during the DTP and EEP are presented.

The initial dose of C.E.R.A. was 120, 200, or 360 mcg IV or SC every 4 weeks for 48 weeks, which was based on the last dose of the previous ESA. Dose adjustments were necessary when Hb increased or decreased by a clinically significant amount. The dose of C.E.R.A. was adjusted to maintain the individual participant's Hb within a range of +/-1.0 g/dL of the reference Hb concentration and between 10.5 and 12.5 g/dL throughout the DTP and the EEP. The reference Hb value was taken as the mean of all Hb assessments during the stability verification period. The mean monthly doses of C.E.R.A during the DTP and EEP are presented.

Red blood cell (RBC) transfusions were permitted during the treatment period in case of medical need. The pre-transfusion Hb level was measured before any transfusion was administered.

The white blood cells (WBC) and thrombocyte levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for WBC are as follows: Female/Male: min-max for lower limit= 3.5 - 5*10^9 cells/L and min-max of upper limit= 9 -13.5*10^9 cells/L. The standard reference ranges for thrombocyte are as follows: Female/Male: min-max for lower limit= 130 - 150*10^9 cells/L and min-max of upper limit= 300 - 450*10^9 cells/L.

The phosphate and potassium levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for phosphate are as follows: Female/Male: min-max for lower limit= 0.48435 - 0.9687 mmol/L and min-max for upper limit=1.45305 - 2.2603 mmol/L. The standard reference ranges for potassium are as follows: Female/Male: min-max for lower limit=3.1 - 3.7 mmol/L and min-max for upper limit=5 - 5.5 mmol/L.

The creatinine, iron, and total iron binding capacity (TIBC) levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for creatinine are as follows: Female: min-max for lower limit=0 - 70.72 mmol/L and min-max for upper limit=79.56 - 123.76 mmol/L; Male: min-max for lower limit=0 - 70.72 mmol/L and min-max for upper limit=97.24 - 123.76 mmol/L. The standard reference ranges for iron are as follows: Female: min-max for lower limit=6.265 - 10.74 mmol/L and min-max for upper limit=25.06 - 32.22 mmol/L and Male: min-max for lower limit=6.265 - 11.635 mmol/L and min-max for upper limit=25.06 - 32.22 mmol/L. The standard reference ranges for TIBC are as follows: Female: min-max for lower limit=19.69 - 49.046 mmol/L and min-max for upper limit=62.65 - 88.963 mmol/L and Male: min-max for lower limit=19.69 - 52.089 mmol/L and min-max for upper limit=62.65 - 80.55 mmol/L.

Transferrin saturation (TSAT) is the ratio of serum iron and total iron-binding capacity. Transferrin is a blood protein that picks up iron absorbed by the intestines and transports it from one location to another. When iron absorption is abnormally high, transferrin proteins become more saturated with iron. An elevated TS value therefore reflects an increase in iron absorption. The TSAT levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. TSAT was calculated automatically in the electronic case report form (eCRF) according to the following formulae: TSAT= (Serum Iron*100)/(Transferrin*1.41) or TSAT=(Serum Iron*100)/TIBC. Calculated data was not provided by laboratory; therefore no reference range is available.

The albumin and transferrin levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for albumin are as follows: Female/Male: min-max for lower limit=30 - 35 g/L and min-max for upper limit=48 - 55 g/L. The standard reference ranges for transferrin are as follows: Female/Male: min-max for lower limit=1.5 - 2.3 g/L and min-max for upper limit=2.87 - 4.3 g/L.

C-reactive protein (CRP) is produced by the liver. The level of CRP rises when there is inflammation throughout the body. The CRP test is a general test to check for inflammation in the body.The CRP levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for CRP are as follows: Female/Male: min-max for lower limit=0 - 10 mg/L and min-max for upper limit=0.5 - 30 mg/L.

Ferritin is a protein found inside cells that stores iron so that the body can use it later. A ferritin test indirectly measures the amount of iron in your blood. The Ferritin levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The standard reference ranges for ferritin are as follows: Female: min-max for lower limit=6 - 50 mcg/L and min-max for upper limit=120 - 400 mcg/L; Male: min-max for lower limit=10 - 50 mcg/L and min-max for upper limit=200 - 400 mcg/L.
