Aims/hypothesisThe renal and cardiovascular protective effects of angiotensin receptor blocker (ARB) remain controversial in type 2 diabetic patients treated with a contemporary regimen including an angiotensin converting enzyme inhibitor (ACEI).MethodsWe examined the effects of olmesartan, an ARB, on primary composite outcome of doubling of serum creatinine, endstage renal disease and death in type 2 diabetic patients with overt nephropathy. Secondary outcome included composite cardiovascular outcomes, changes in renal function and proteinuria. Randomisation and allocation to trial group were carried out by a central computer system. Participants, caregivers, the people carrying out examinations and people assessing the outcomes were blinded to group assignment.ResultsFive hundred and seventy-seven (377 Japanese, 200 Chinese) patients treated with antihypertensive therapy (73.5% [n = 424] received concomitant ACEI), were given either once-daily olmesartan (10–40 mg) (n = 288) or placebo (n = 289) over 3.2 ± 0.6 years (mean±SD). In the olmesartan group, 116 developed the primary outcome (41.1%) compared with 129 (45.4%) in the placebo group (HR 0.97, 95% CI 0.75, 1.24; p = 0.791). Olmesartan significantly decreased blood pressure, proteinuria and rate of change of reciprocal serum creatinine. Cardiovascular death was higher in the olmesartan group than the placebo group (ten vs three cases), whereas major adverse cardiovascular events (cardiovascular death plus non-fatal stroke and myocardial infarction) and all-cause death were similar between the two groups (major adverse cardiovascular events 18 vs 21 cases, all-cause deaths; 19 vs 20 cases). Hyperkalaemia was more frequent in the olmesartan group than the placebo group (9.2% vs 5.3%).Conclusions/interpretationOlmesartan was well tolerated but did not improve renal outcome on top of ACEI.Trial registration: ClinicalTrials.gov NCT00141453Funding: The ORIENT study was supported by a research grant from Daiichi Sankyo.Electronic supplementary materialThe online version of this article (doi:10.1007/s00125-011-2325-z) contains peer-reviewed but unedited supplementary material, including a list of the ORIENT study investigators, which is available to authorised users.
Background: There is strong biologic plausibility to support change in albuminuria as a surrogate endpoint for progression of chronic kidney disease (CKD), but empirical evidence to supports its validity in epidemiologic studies is lacking. Methods: We analyzed 28 cohorts including 693,816 individuals (80% with diabetes) and 7,461 end-stage kidney disease (ESKD) events, defined as initiation of kidney replacement therapy. Percent change in albuminuria was quantified during a baseline period of 1, 2 and 3 years using linear regression. Associations with subsequent ESKD were quantified using Cox regression in Coresh et al.
Exposure levels in healthy adults receiving esaxerenone were generally dose-proportional. Dose-dependent changes in plasma pharmacodynamic biomarkers for the mineralocorticoid receptor were identified during multiple-dose treatment and support the pharmacological activity of esaxerenone. No important safety concerns were identified.
Cardiovascular events tend to occur in the morning, along with a peak in ambulatory BP, 6 and of clinic, 24-hour, awake, sleep, evening, preawake, and morning BP, morning systolic BP (SBP) is the strongest independent predictor for stroke. Therefore, antihypertensive treatment for morning hypertension is likely to offer greater benefit in preventing cardiovascular events.Abstract-This study aimed to investigate the relationship between on-treatment morning home blood pressure (HBP) and incidence of cardiovascular events using data from the
