Dihydropyridine calcium channel blockers may possess antioxidant properties, and might improve micro and macrovascular structure and function. Combination treatment with an ACE inhibitor may have additional advantages, compared with a thiazide diuretic. The aim of the present study is to investigate the effects of a short-term treatment with lercanidipine, and to compare two combination treatments: lercanidipine + enalapril vs. lercanidipine + hydrochlorothiazide on structural alterations in retinal arterioles, on skin capillary density and on large artery distensibility...

Retreat in psychiatric drug development results in innovative medication decline that might be at least partially overcome by adjunct therapy. New evidence from clinical studies has shown a possible role for brain Renin-Angiotensin System (RAS) in both affective and psychotic disorders. Simultaneously, rapidly accumulating data from basic studies indicate effectiveness of central RAS blockade in much broader range of neuropsychiatric disease. Recent findings implicate brain RAS, especially Angiotensin II (Ang II), in neural pathophysiology of mental disorders through neuroendocrine modulation and effects on neurotransmitter release, mostly noradrenaline, acetylcholine and dopamine...

The renin-angiotensin system (RAS) is a key regulator of blood pressure and blood volume homeostasis. The RAS is primarily comprised of the precursor protein angiotensinogen and the two proteases, renin and angiotensin-converting enzyme (ACE). Angiotensin I (Ang I) is derived from angiotensinogen by renin, but appears to have no biological activity. In contrast, angiotensin II (Ang II) that has a variety of biological functions in the cells is converted from Ang I through removal of two-C-terminal residues by ACE...

A novel strategy was developed for dual-target screening of bioactive components from traditional Chinese medicines (TCMs). This strategy was based on the use of low-cost microporous hollow fibers filled with target enzymes as baits to "fish out" the ligands in TCM extracts, followed by identification of the ligands dissociated from the target-ligand complexes by liquid chromatography-mass spectrometry. Ganjiang Huangqin Huanglian Renshen Decoction (GHHRD), a classical TCM prescription for diabetes treatment, was chosen as a model sample to evaluate the feasibility of the proposed strategy...

OBJECTIVE: Cardiovascular conditions are the second cause of death in Puerto Rico. The individual use of angiotensin-converting enzyme inhibitors (ACE-Is) or angiotensin receptor blockers (ARBs) is considered the first-line therapy for the treatment of several cardiovascular-related medical conditions. However, the concurrent use of these 2 therapeutic classes of drugs is not supported by treatment guidelines. Studies have shown that their concurrent use represents a potential health risk...

We report a 14-year-old boy with recurrent episodes of headache caused by uncontrolled hypertension. The diagnosis of renovascular hypertension due to Takaysu arteritis (TA) was made based on an increase in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and computed tomography (CT) image of bilateral renal artery stenosis was taken. Renal scintigraphy revealed normal perfusion and function of the right kidney and severe reduction of the perfusion and function of the left kidney. Careful drug adjustments significantly improved but did not fully control the blood pressure (BP); further, angioplasty, which showed almost occlusion of the left renal artery opening and the minor narrowing of the right renal artery, failed to regain sufficient BP control...

BACKGROUND: It is generally believed that essential hypertension is influenced by both genetic and environmental factors, as well as their interactions. Tissue kallikrein encoded by the tissue kallikrein gene (KLK1) is a key serine proteinase of kallikrein-kinin system, which is capable of generating potent vasactive peptides, kinins, by selective cleavage of the kininogen substrate. It was reported that the A2233 → C polymorphism in KLK1 gene is associated with essential hypertension...

The renin-angiotensin system (RAS) is undisputedly one of the most prominent endocrine (tissue-to-tissue), paracrine (cell-to-cell) and intracrine (intracellular/nuclear) vasoactive systems in the physiological regulation of neural, cardiovascular, blood pressure, and kidney function. The importance of the RAS in the development and pathogenesis of cardiovascular, hypertensive and kidney diseases has now been firmly established in clinical trials and practice using renin inhibitors, angiotensin-converting enzyme (ACE) inhibitors, type 1 (AT1) angiotensin II (ANG II) receptor blockers (ARBs), or aldosterone receptor antagonists as major therapeutic drugs...

BACKGROUND/AIMS: Arterial hypertension is characterized by vascular remodelling, atherosclerosis and cardiovascular complications. Matrix metalloproteases (MPPs) are endopeptidases produced by all the cells present in the vascular wall and are involved in the regulation of the extracellular matrix protein turnover. MMPs contribute to blood vessel formation, remodelling, angiogenesis; whereas an altered expression or activity of MMPs or their tissue inhibitors (TIMPs) results correlated with the development and progression of cardiovascular complications...

OBJECTIVES: Angiotensin-converting enzyme inhibitors (ACE-I) and AT1 blockers (ARB) are commonly used antihypertensive drugs, but several factors may affect their effectiveness. We evaluated the associations between ambulatory blood pressure (BP) monitoring (ABPM) parameters and plasma renin activity (PRA)-to-plasma aldosterone concentration (PAC) ratio (RAR) to test renin-angiotensin-aldosterone system inhibition in essential hypertensive patients treated with ACE-I or ARB for at least 12 months...

The onset of microalbuminuria (MA) heralds the onset of glomerulopathy in patients with glycogen storage disease (GSD) type I. Unlike tubulopathy, which responds to improved metabolic control, glomerulopathy in GSD I is considered refractory to medical intervention, and it is thought to inexorably progress to overt proteinuria and renal failure. Recent reports of reduced microalbuminuria following strict adherence to therapy counter this view. In contrast to type Ia, little is known regarding the prevalence of kidney disease in GSD Ib, 0, III, VI, and IX...

BACKGROUND: Endothelial dysfunction (ED) has emerged as a critical process in cardiorenal syndrome (CRS). The concept that ED is closely linked with cardiac and renal dysfunction has become an important target for CRS-related research and clinical practice. SUMMARY: The sequence of events leading to ED is initiated by type I endothelial activation (almost immediately) and type II endothelial activation (over hours, days, and even months), followed by endothelial apoptosis and endothelial necrosis...

The therapeutic targeting of prostanoid subtype receptors may slow the development of chronic kidney disease (CKD) through mechanisms that are distinct from those of upstream COX inhibition. Here, employing multiple experimental models of CKD, we studied the effects of inhibition of the EP4 receptor, one of four receptor subtypes for the prostanoid prostaglandin E2. In streptozotocin-diabetic endothelial nitric oxide synthase knockout mice, EP4 inhibition attenuated the development of albuminuria, whereas the COX inhibitor indomethacin did not...

High-end analytical methods provide excellent data but may lack the robustness required in large analytical studies. In particular complex chemical matrices may cause difficulties and increase the need for extensive sample preparation. For screening of patients we thus developed a low-tech assay to monitor bradykinin degradation by serum proteases. The bradykinin concentration mirrors the activity of angiotensin-converting enzyme (ACE). Dabsylated bradykinin (DBK) and its labeled fragments DBK1-8 and DBK1-5 were visualized by thin-layer chromatography using only 3μL of serum...

The renin-angiotensin-aldosterone system (RAAS) plays a key role in the pathophysiology of arterial hypertension as well as in more complex mechanisms of cardiovascular and renal diseases. RAAS-blocking agents like angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers, have long been key components in the treatment of essential hypertension, heart failure, diabetic nephropathy, and chronic kidney disease, showing benefits well beyond blood pressure reduction. Renin blockade as the first step of the RAAS cascade finally became possible in 2007 with the approval of aliskiren, the first orally active direct renin inhibitor available for clinical use and the newest antihypertensive agent on the market...
