Key Player Identified In Cascade That Leads To Hypertension-Related Kidney Damage
Source: Hypertension News From Medical News Today [2009.11.06]
A key player in a cascade that likely begins with stress and leads to high blood pressure and kidney damage has been identified by researchers who say the finding may lead to better ways to control both. Medical College of Georgia researchers have found endothelin, a powerful blood vessel constrictor and inflammatory peptide, increases the number of T cells in the kidneys, which helps recruit other immune cells, causing inflammation and destruction.

A diet high in fructose increases the risk of developing high blood pressure (hypertension), according to a paper presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, California. The findings suggest that cutting back on processed foods and beverages that contain high fructose corn syrup (HFCS) may help prevent hypertension.

A Task Force of the European Society of Hypertension have released the official European guidelines on the management and treatment of hypertension. The guidelines are an update of those published in 2007, and will be published in the November issue of the Journal of Hypertension.
Published Studies Related to Atenolol and Chlorthalidone (Atenolol / Chlorthalidone)
Antihypertensive therapy with verapamil SR plus trandolapril versus atenolol plus chlorthalidone on glycemic control. [2003.05]
BACKGROUND: There is evidence that diuretics and beta blockers impair glucose tolerance, whereas calcium channel blockers and angiotensin converting enzyme blockers lack this metabolic effect. We compared the effect of a combination therapy with a nondihydropyridine calcium channel blocker plus an angiotensin converting enzyme inhibitor and a beta blocker plus a diuretic on hemoglobin A(1c) (Hb A(1c)) in patients with type 2 diabetes and mild-to- moderate hypertension... CONCLUSIONS: HbA(1c) and other parameters of short- and long-term glycemic control were in a more favorable range after antihypertensive treatment with verapamil SR plus trandolapril as compared with atenolol plus chlorthalidone.
Effect of atenolol and reserpine on selected events in the systolic hypertension in the elderly program (SHEP). [1995.12]
The effect of atenolol and reserpine on incidence of strokes, coronary heart disease (CHD), cardiovascular disease (CVD), and mortality was assessed in 4736 persons aged 60 years and older with isolated systolic hypertension. Participants were randomized to either chlorthalidone (2371), with step-up to atenolol, or reserpine if needed, or placebo (2365)...
Randomised double-blind comparative study of efficacy and safety of hydroflumethiazide and reserpine and chlortalidone and atenolol in the treatment of mild to moderate hypertension in black patients. [1993.10]
This randomised, double-blind study compared the efficacy and safety of a fixed combination of hydroflumethiazide 50 mg and reserpine 0.125 mg (H-R) and chlortalidone 12.5 mg and atenolol 50 mg (C-A) in adult black patients with mild to moderate hypertension (a resting supine diastolic blood pressure (DBP) between 95 and 115 mmHg after a two week placebo washout period)...
Comparative effects of enalapril, atenolol and chlorthalidone on blood pressure and kidney function of diabetic patients affected by arterial hypertension and persistent proteinuria. [1991]
Arterial hypertension and proteinuric nephropathy are common features in diabetic patients. In streptozotocin-diabetic rats, it has been possible to reduce the blood pressure and proteinuria by converting enzyme inhibitors, and so slowing the decline of kidney function... According to these results we can hypothesize that the inhibition of tissue angiotensin formation and its related change on the glomerular permeability, rather than renal and systemic hemodynamic features, seem to be the common mechanisms by which both enalapril as well as atenolol decrease the albuminuria in our patients.
[A comparative study of atenolol (Tenormin) and the combined preparation atenolol/chlorthalidone (Tenoretic Mite) in essential hypertension. A randomized double-blind study from general practice] [1990.04.09]
Two hundred and ninety-two hypertensive patients from general practice who had previously been treated with a diuretic with insufficient effect participated in a randomised trial for a period of three months. A total of 115 patients completed treatment with 50 mg atenolol (Tanormin) and 121 were treated with the combined preparation consisting of 50 mg atenolol and 12.5 mg chlothalidone (Tenoretic Mite) while 56 patients defected from the trial.
Clinical Trials Related to Atenolol and Chlorthalidone (Atenolol / Chlorthalidone)
VALENCE: Valsartan Versus Atenolol on Exercise Capacity in Hypertensive Overweight Postmenopausal Women [Completed]
The purpose of the study is to show that valsartan compared to atenolol has favorable effects
on exercise capacity, quality of life, diastolic function and elevated blood pressure in
hypertensive postmenopausal overweight women with impaired exercise tolerance despite normal
left ventricular ejection fraction (LVEF).
A Pilot Study Comparing Nebivolol and Atenolol and Its Effects With Exercise in Patients With Mild to Moderate Hypertension [Completed]
Perioperative Effect of Atenolol on Cytokine Profiles [Active, not recruiting]
Studies have shown that beta-blockers such as atenolol when given in the perioperative period
reduce morbidity and mortality. One study showed that atenolol given just during the surgery
period, seemed to improve outcomes up to 2 years later. This is hard to explain since
beta-blockers act on the body by blocking the effects of adrenalin and thereby lowering heart
rate and blood pressure.
This study is designed to find out if perioperative atenolol might exert its long term
effects through an anti-inflammatory mechanism rather than by lowering heart rate and blood
pressure. It is known that inflammation increases after surgery as part of the healing
process. However, it is also becoming clear that low-grade chronic inflammation can also lead
to long term adverse effects.
A Comparison of the Effect of Olmesartan Medoxomil, Losartan Potassium, and Atenolol on the Ability of Overweight Patients With High Blood Pressure to Respond to Insulin [Completed]
To examine the effect of three different blood pressure medications on the insulin
sensitivity in overweight patients with high blood pressure.
Effects of Losartan Versus Atenolol on Aortic and Cardiac Muscle Stiffness in Adults With Marfan Syndrome [Recruiting]
Marfan syndrome is an inherited connective tissue disorder with morbidity and mortality from
aortic dilation and dissection. The degree of aortic dilation and response to beta-blockade
(standard of care) vary in adults with Marfan syndrome. However, aortic stiffness is often
present, and can be a predictor of aortic dilation and cardiovascular complications. In
addition, adults with Marfan syndrome develop left ventricular diastolic dysfunction, which
can progress to heart failure. Aortic stiffness and diastolic dysfunction are important and
logical therapeutic targets in adults with Marfan syndrome.
TGF-beta mediates disease pathogenesis in Marfan syndrome and contributes to aortic
stiffness. The angiotensin receptor blocker, losartan, inhibits TGF-beta activity and
reverses aortic wall pathology in a Marfan mouse model. Losartan also decreases aortic
stiffness and improves diastolic function in hypertension, renal disease and hypertrophic
cardiomyopathy.
This trial is a randomized, double-blind trial of 50 adults with Marfan syndrome, treated
with 6 months of atenolol vs. losartan. Arterial tonometry for aortic stiffness and
echocardiography for diastolic function will be performed at the beginning and end of
treatment. A blood draw for serum markers of extracellular matrix turnover and inflammation
will also be performed at 0 and 6 months. We plan to determine whether losartan decreases
aortic stiffness and left ventricular diastolic dysfunction significantly more than
atenolol.
