Effects of Aliskiren in Elderly Hypertensive Chronic Kidney Disease (CKD) Patients
Effects of Aliskiren on Blood Pressure, Heart and Kidney in Elderly Hypertensive Chronic Kidney Disease Patients
調査の概要
詳細な説明
Chronic kidney disease (CKD) was reported to be affecting 11% of the all population. This number is much higher in the elderly population and may be as high as 30%. CKD is an independent risk factor of cardiovascular disease (CVD). This is called "Cardio-renal Continuum". The renin-angiotensin-aldosterone system (RAS) plays pivotal roles in both cardiovascular and renal functions.
The increased oxidative stress by activated RAS on vascular endothelium is one of important factor to development of Cardio-renal Continuum. The blockade of RAS by angiotensin I converting enzyme inhibitors (ACEIs) and/or angiotensin receptor blockers (ARBs) has been reported to ameliorate the renal disease and CVD; however,they do not completely suppress RAS, leading to a reactive rise in plasma renin activity (PRA). Aliskiren, an oral direct renin inhibitor, is effective against essential hypertension by reducing PRA, resulting in more complete suppression of RAS; however, little is known about the effects of aliskiren on heart and kidney functions in elderly hypertensive CKD patients. In this study, we assessed the efficacy of aliskiren on heart and kidney functions in elderly hypertensive CKD patients.

The Change of eGFR
時間枠:baseline and 6 month
|
eGFR was calculated at baseline and at 6 month using a modified version of the Modification of Diet in Renal Disease (MDRD) formula of the Japanese Society of Nephrology as follows: eGFR (ml/min/1.73
m2) = 194 × age-0.287
× serum creatinine-1.094
(multiplied by 0.739 for females).
