Pediatrics: Blood pressure target for renoprotection in children

Mak RH, Flynn J, Bakris G.   Nat Rev Nephrol.   2010 Feb;6(2):67-8

This review summarizes results of the landmark ESCAPE trial, which has shown that lowering the blood pressure target to below the 50th percentile slows pediatric chronic kidney disease progression.

Prehypertension: epidemiology, consequences and treatment

Pimenta E, Oparil S, Medscape.   Nat Rev Nephrol.   2010 Jan;6(1):21-30

This review of prehypertension emphasizes the importance of diagnosing this entity early as a view to preventing cardiovascular outcomes in the population as a whole and not just those patients at high-risk.

Usual versus tight control of systolic blood pressure in non-diabetic patients with hypertension (Cardio-Sis): an open-label randomised trial.

Verdecchia P, Staessen JA, Angeli F, de Simone G, Achilli A, Ganau A, Mureddu G, Pede S, Maggioni AP, Lucci D, Reboldi G, Cardio-Sis investigators.   Lancet.   2009 Aug 15;374(9689):525-33

It has long been recognized from epidemiologic studies that cardiovascular risk increases at blood pressures far below the current hypertension treatment target of 140/90. This open-label, blinded endpoint study randomized patients with uncontrolled hypertension to a systolic BP target of <130 mm Hg or <140 mm Hg. They showed a reduction in both the primary [...]

Treatment blood pressure targets for hypertension.

Arguedas JA, Perez MI, Wright JM.   Cochrane Database Syst Rev.   2009 Jul 8;(3):CD004349

In the meta-analysis, no reduction in morbidity or mortality benefit was found when hypertensive patients are targeted to a lower target of ≤ 135/85 mmHg as compared to a BP targets of ≤ 140-160/ 90-100 mmHg. Of note, no trials comparing different systolic BP targets were included in the analysis. Nephrology Now readers will likely be [...]

Effects of valsartan on morbidity and mortality in uncontrolled hypertensive patients with high cardiovascular risks: KYOTO HEART Study

Sawada T, Yamada H, Dahlöf B, Matsubara H, KYOTO HEART Study Group.   Eur Heart J.   2009 Oct;30(20):2461-9

This trial using a PROBE design compared add-on therapy with an ARB as compared to alternative antihypertensive agents in Japanese patients with uncontrolled hypertension. A reduction in hard clinical endpoints was observed in the Valsartan add-on group.

Antihypertensives for Kidney Transplant Recipients: Systematic Review and Meta-Analysis of Randomized Controlled Trials

Cross NB, Webster AC, Masson P, O'connell PJ, Craig JC.   Transplantation.   2009 Jul 15;88(1):7-18

Hypertension is common post-renal transplant and is associated with an
increased risk of graft loss and death. This meta-analysis found the
strongest evidence for calcium-channel blockers in reducing graft loss and
improving GFR. ACE-inhibitors did not reduce the incidence of graft loss and
were associated with a lower GFR, but did reduce proteinuria.

Effect of Telmisartan on Renal Outcomes: A Randomized Trial.

Bilous R, Chaturvedi N, Sjølie AK, Fuller J, Klein R, Orchard T, Porta M, Parving HH.   Ann Intern Med.   2009 Jul 7;151(1):11-20, W3-4

This pre-specified subgroup analysis of the TRANSCEND study failed to show any significant benefit on renal outcomes between the intervention arm (using telmisartan) and placebo arm. This was not a study of chronic kidney disease patients, but rather examined patients with cardiovascular disease or diabetes, but without macroalbuminuria or heart failure.
