Effect of olmesartan on diurnal blood pressure profile, vascular function, oxidative stress, and renal renin-angiotensin system in hypertensives with chronic kidney disease

Basic Information

Recruitment status Complete: follow-up complete
Health condition(s) or Problem(s) studiedHypertension with chronic kidney disease
Date of first enrollment2007/11/01
Target sample size200
Countries of recruitmentJapan
Study typeInterventional
Intervention(s)Olmesartan group: To achieve blood pressure control below 130/80 mmHg, start with once-daily dosing of olmesartan 5-10 mg, and increase up to 10-40 mg if effect of olmesartan on the clinical parameters is insufficient. If necessary, a combination therapy by several anti-hypertensives will be performed to achive casual blood pressure control below 130/80 mmHg. Control group: To achieve blood pressure control below 130/80 mmHg, start with anti-hypertensives including ACE inhibitor but other than ARBs, and increase dosage of respective anti-hypertensives if effect of first-line anti-hypertensives on the clinical parameters is insufficient. If necessary, a combination therapy by several anti-hypertensives will be performed to achive casual blood pressure control below 130/80 mmHg.

Outcome(s)

Primary Outcome1) Abdominal circumference 2) Casual blood pressure, home blood pressure. 3) Diurnal blood pressure profile by ambulatory blood pressure monitoring. 4) Glucose metabolism: FPG, IRI, HbA1c. 5) Renal function: Urinary protein excretion, BUN, urinary creatinine excretion, urinary albumin excretion, eGFR, urinary type IV collagen excretion. 6) Lipid metabolism: total cholesterol, LDL cholesterol, tryglyceride, HDL-choresterol. 7) Cardiac function: BNP. 8) Vascular function: ABI/PWV, FMD. 9) Inflamation and oxidative stress marker: hs-CRP, adiponectin, plasma apelin, urinary 8-OHdG. 10) Markers of intra-renal renin-angiotensin system: plasma and urinary angiotensinogen. 11) Genotype of renin-angiotensin system: angiotensinogen, renin, AT1 receptor, ATRAP, Nedd4L. 12) Examination of renal biopsy specimen (glomerular sclerosis, fibrosis, and expression of ATRAP and AT1 receptor mRNA and protein).
