Angiotensin II receptor antagonists (ARBs), originally developed for antihypertensive properties, have pleiotropic effects including direct vascular actions. We tested the hypothesis that the ARB irbesartan would be effective against micro- and macrovascular complications of the prediabetic metabolic syndrome using the obese, insulin-resistant JCR : LA-cp rat that exhibits micro- and macrovascular disease with ischaemic myocardial lesions and renal disease.
Both treatment regimens enhanced serum IL-10 levels (IRB p < 0.001, ENAL p < 0.03) and reduced serum MMP-9 protein (IRB p < 0.001, ENAL p < 0.05) and MMP-9 activity (IRB p < 0.005, ENAL p < 0.05). Only IRB reduced serum IL-6 and hsCRP levels significantly compared with baseline (p < 0.01), whereas ENAL did not (hsCRP p < 0.02 IRB vs. ENAL, p < 0.01 IRB vs. ENAL). Platelet aggregation was only reduced by IRB (p < 0.001, ENAL p < 0.06, IRB vs. ENAL p < 0.001) while urine PGE(2) levels remained unchanged.

This study was designed to assess whether angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) could prevent the recurrence of atrial fibrillation (AF).
Hypercholesterolemia is an important risk factor for atherosclerotic vascular disease including stroke. Low-density lipoprotein-cholesterol may induce upregulation of angiotensin II type 1 (AT1)-receptors and their activation plays a pathogenetic role in atherosclerosis, possibly via enhanced breakdown of nitric oxide. We tested whether AT1-receptor blockade improved endothelial function of the retinal vasculature in normocholesterolemic and hypercholesterolemic subjects.

During the development of ISH, drug treatment appears more beneficial when started early. Indeed, the three agents prevented PP elevation, aortic calcification and C/E increase in the aorta, and hypertrophy in small arteries. In contrast, once the disease is established, endothelin appears crucial in the maintenance of aortic calcification, while angiotensin II sustains small artery hypertrophy.
Microalbuminuria and hypertension are risk factors for diabetic nephropathy. Blockade of the renin-angiotensin system slows the progression to diabetic nephropathy in patients with type 1 diabetes, but similar data are lacking for hypertensive patients with type 2 diabetes. We evaluated the renoprotective effect of the angiotensin-II-receptor antagonist irbesartan in hypertensive patients with type 2 diabetes and microalbuminuria.

Acute myocardial infarction resulted in a significant increase of LVEDP (P < 0.05), LVDd (P < 0.01), and VW/BW (P < 0.01), and total collagen (at 2 weeks 6.1 +/- 0.7 vs 3.6 +/- 0.5 and at 6 weeks 5.1 +/- 0.8 vs 3.6 +/- 0.4, P < 0.01) in noninfarcted region. Treatment with fosinopril, irbesartan and combination of these two drugs improved them. At the sixth week, irbesartan and combination therapy decreased more significantly total collagen compared with fosinopril (3.4 +/- 0.7 and 3.3 +/- 0.7 vs 4.2 +/- 0.6, P < 0.05). The level of eNOS mRNA expression increased more significantly in combination therapy group than in fosinopril or irbesartan group alone (at 2 weeks 1.55 +/- 0.17, at 6 weeks 1.61 +/- 0.16, P < 0.01). eNOS protein increased.
avapro vs generic
Four weeks of high-salt diet in wild-type mice, which rapidly caused glomerular eNOS activation and subsequent increase in nitric oxide, did not at all induce renal injury, indicating that wild-type mice are salt-resistant. On the contrary, high-salt diet in eNOS-/- mice, which little increased nitric oxide, rapidly increased urinary albumin excretion, followed by glomerular macrophage infiltration and glomerular sclerosis. Thus, eNOS deficiency caused salt-sensitive glomerular injury. Salt-induced glomerular injury in eNOS-/- mice was preceded by rapid enhancement of glomerular superoxide followed by enhancement of glomerular endothelial angiotensinogen and angiotensin II. Irbesartan and tempol, independently of blood pressure, markedly prevented salt-induced glomerular injury in eNOS-/- mice, and these protective effects were attributed to the attenuation of glomerular oxidative stress and glomerular angiotensinogen-derived angiotensin II.

We determined the preproendothelin-1 genotype using minisequencing in 102 patients with essential hypertension and LV hypertrophy verified by echocardiography, randomized in a double-blind fashion to treatment with either the AT1-receptor antagonist irbesartan or the beta1-adrenoceptor antagonist atenolol.
Molecular modeling has proven valuable to generate testable hypotheses concerning receptor/ligand binding and is an important tool in drug design. ARBs were designed to act as antagonists for AT2R1, and it was not surprising to discover their affinity for the structurally similar CCR2b. However, this study also found evidence that ARBs modulate the activation of two key nuclear receptors-VDR and PPARgamma. If our simulations are confirmed by experiment, it is possible that ARBs may become useful as potent anti-inflammatory agents, in addition to their current indication as cardiovascular drugs.
Ang II surprisingly ameliorates glomerular monocyte infiltration, proliferation and matrix expansion in ATS nephritis. Ang II-mediated induction of cyclin kinase inhibitors and TGF-beta may contribute to the protection of the glomerulus from inflammatory injury by inducing cell cycle arrest and attenuating activation of local and recruited cells. Alternatively, Ang II might protect the kidney at least in part by less inflow of disease activators due to reduction of renal blood flow. Therefore, activation of the renin-angiotensin system may have protective effects in certain pathophysiological situations.

A total of 238 patients were randomized to treatment, 115 to irbesartan and 123 to enalapril. The study population was approximately 52.0% female and 48.0% male, with a mean ( +/- SD) age of 52.7 +/- 10.6 years. The study was completed by 111 patients in the irbesartan group (dose titrated to 300 mg/d in 72.0% of patients) and 115 patients in the enalapril group (dose titrated to 20 mg/d in 76.5% of patients). BP reductions were similar in the 2 groups, both as measured in the clinic (DBP, 12.7 +/- 8.8 mm Hg irbesartan vs 12.4 +/- 7.4 mm Hg enalapril; SBP, 19.0 +/- 14.1 mm Hg vs 17.5 +/- 14.0 mm Hg) and by 24-hour ABPM (DBP, 9.4 +/- 8.5 mm Hg vs 8.8 +/- 8.5 mm Hg: SBP, 14.7 +/- 14.7 mm Hg vs 12.6 +/- 13.1 mm Hg). As assessed by ABPM, rates of BP control were 40.5% (45/111) for irbesartan and 33.9% (39/115) for enalapril, and the response rates were a respective 71.2% (79/111) and 71.3% (82/115). The overall incidence of adverse events (40.0% irbesartan, 51.2% enalapril) was not statistically different between groups, although the incidence of adverse events considered probably related to antihypertensive treatment was significantly higher with enalapril than with irbesartan (24.6% vs 9.2%, respectively; P = 0.026), essentially because of the higher incidence of cough (8.1% vs 0.9%).
3T3-L1 cells induced with isobutylmethylxanthine, insulin and dexamethasone to differentiate into adipocytes were stimulated by LPS with or without irbesartan pretreatment. The expression levels of TLR4, angiotensinogen (AGT) and angiotensin II receptor type 1 (ATlR) mRNA in 3T3-L1 cells was determined by RT-PCR, and their protein expressions were detected with Western-blotting. Immunofluorescence double staining was used to observe the translocation of NF-κB p65 subunit in the cells.

Circulating microparticles are increased in cardiovascular disease and may themselves promote oxidative stress and inflammation. Molecular mechanisms underlying their formation and signaling are unclear. We investigated the role of reactive oxygen species (ROS), Rho kinase, and lipid rafts in microparticle formation and examined their functional significance in endothelial cells (ECs).
Abelmoschus manihot (L.) medic (AM) is a natural medicinal plant used for the treatment of chronic kidney disease (CKD) in China. Huangkui capsule (HKC), an extract from AM, has been proved clinically effective in improving renal inflammation and glomerular injury in CKD. However, the mechanisms of HKC are still not fully understood.

Nineteen women (mean age, 54.7 years; range, 43-72 years; 7 normotensive subjects [mean age, 53.4 years; range, 47-61 years] and 12 hypertensive subjects [mean age, 55.4 years; range, 43-72 years]) were included in the study. When the data for all 19 subjects were pooled, ABP was significantly lower with irbesartan than placebo both during the day (120 /79  vs 127 /85  mm Hg; both, P < 0.01) and at night (systolic BP, 107  vs 111  mm Hg [P < 0.01] and diastolic BP, 71  vs 75  mm Hg [P < 0.05]). Compared with placebo, irbesartan was not associated with a significant change in GFR in either the normotensive or the hypertensive women. When the data for all 19 subjects were pooled, irbesartan was associated with a significant increase in ERPF compared with placebo (372  vs324  mL/min · 1.73 m(2); P < 0.05). When the hypertensive and normotensive women were considered separately, the effect was more pronounced in the hypertensive women than in the normotensive women, but the changes did not reach statistical significance. When the data for all subjects were pooled, irbesartan was associated with a significant increase in daytime urinary sodium excretion compared with placebo (135  vs 106  μmol/min; P < 0.05) and a significant decrease at night (109  vs 136  μmol/min; P < 0.05). Fractional excretion of lithium (FELi), an inverse marker of proximal sodium reabsorption, increased significantly during the daytime with irbesartan compared with placebo (47% [6.5%] vs 35% [4.7%]; P < 0.05). At nighttime, FELi was significantly higher in the hypertensive subjects receiving irbesartan compared with placebo (43% [7.2%] vs 29% [6.5%]; P < 0.05). The fractional distal reabsorption of sodium did not change significantly with irbesartan compared with placebo.
Irbesartan, an AT1 antagonist, prevents fibrosis and inflammation and inhibits nitric oxide production in HOCl-induced models of systemic fibrosis. Our findings extend the indication of an AT1 antagonist to SSc patients with diffuse fibrosis, especially those with lung involvement.

To compare diverse effects of angiotensin II type 1 receptor antagonists (irbesartan) and angiotensin converting enzyme inhibitors (imidapril) on left ventricular remodeling in spontaneously hypertensive rats (SHR). Thirty male SHR were randomly divided into three groups: SHR-IR (treated with irbesartan, 50 mg/kg), SHR-IM (imidapril, 3 mg/kg), SHR-C (placebo). Ten male Wistar Kyoto rats (WKY) treated with placebo acted as the control. All treatments were administered once daily from 14 to 27 weeks of age. Imidapril and irbesartan have the similar inhibitor effects on blood pressure and left ventricular mass indexes in SHR. Despite both drugs suppressed ERK-1 protein expression, decreased cardiomyocytes apoptosis index, blocked collagen type I deposition, reduced TGF-beta(1) gene expression in SHR, imidapril elicits a stronger inhibitory effect. Irbesartan had little effect on MKP-1 protein expression, but imidapril decreased it significantly. As a result, the ERK-1/MKP-1 ratio in SHR-IR was significantly greater than that in SHR-IM (P < 0.05). These results suggest that the balance between MKP-1 and ERKs in myocardial tissue is important for cardiac cell proliferation and growth. They also indicate that the similar efficacy of antihypertensive treatment in reducing blood pressure does not predict the similar capacity to control the individual facet of left ventricular remodeling. Irbesartan is more effective in regressing the homeostasis between ERK-1 and MKP-1, however imidapril is superior in suppressing apoptosis and collagen synthesis in cardiac tissue.
