Effect of Aliskiren on Albuminuria as Measured by Urinary Albumin Excretion Rate (UAER)
Časové okno: 26 weeks
|
Two 24-hour collections of urine were to be made at each study visit.
The arithmetic mean of the two collections were planned to be used in the calculation of summary statistics and the statistical analyses.

Mean Sitting Systolic Blood Pressure (msSBP)
Časové okno: 26 weeks
|
At study entry, blood pressure (BP) was measured in both arms.
If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used.
If there was no clinically significant difference between arms, the non-dominant arm was used through out study.
Systolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes.
For each sitting assessment, blood pressure was assessed at least 3 times.
From these assessments, msSBP was calculated.
All BP measurements were to be performed on the same arm.

Mean Sitting Diastolic Blood Pressure (msDBP)
Časové okno: 26 weeks

At study entry, blood pressure (BP) was measured in both arms.
If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used.
If there was no clinically significant difference between arms, the non-dominant arm was used through out study.
Diastolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes.
For each sitting assessment, blood pressure was assessed at least 3 times.
From these assessments, msDBP was calculated.
All BP measurements were to be performed on the same arm.

Mean Glomerular Filtration Rate (GFR) as Measurement of Renal Function
Časové okno: 26 weeks
|
All patients had to visit the main center for renal function measurements.
The measurements were performed using the constant infusion method with I-iothalamate (IOT) and I-hippuran.
GFR was calculated as the urinary clearance of IOT.

Plasma Rennin Activity (PRA)
Časové okno: Baseline to week 26
|
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26.
Plasma PRA is a direct measure of the formation of Ang I in the plasma.

Plasma Rennin Concentration (PRC)
Časové okno: Baseline to week 26
|
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26.
PRC measures the concentration of immunoactive renin in the plasma.
