Hyperuricemia and renal function

Abstract: Increased serum urate concentration is commonly seen in clinical practice. It does not represent a specific disease, nor is it an indication for therapy. Hyperuricemia can be the consequence of increased uric acid production and/or decreased renal capacity to excrete uric acid. In essential hypertension, it has been described in up to one third of patients and is directly related to an increase in renal vascular resistance and inversely correlated with renal plasma flow. In other words, abnormal renal hemodynamics, commonly seen in the initial stages of the disease, account for the increased serum urate concentration. This can be maintained if a decrease in glomerular filtration rate takes place. The increase in uric acid has been shown to be a potent predictor of the development of cardiovascular events and death. In addition, uric acid, particularly when elevated, could represent an independent risk factor. On the other hand, an altered renal function predicts in an independent manner a higher cardiovascular risk. For this reason, the predictive capacity of uric acid could be partly dependent on the fact that hyperuricemia runs in parallel with a deranged renal function.

Losartan Reduces Phenylephrine Constrictor Response in Aortic Rings From Spontaneously Hypertensive Rats: Role of Nitric Oxide and Angiotensin II Type 2 Receptors

Abstract: Nitric oxide seems to be involved in the mechanisms underlying the antihypertensive and renal responses of losartan in spontaneously hypertensive rats (SHR). We investigated the contribution of nitric oxide to the effect of this angiotensin II (Ang II) type 1 (AT1) receptor antagonist on the constrictor response of phenylephrine in aortic rings from SHR. Furthermore, since it has been suggested that Ang II could bind to unblocked AT2 receptors, during administration of an AT1 receptor antagonist, we also studied the effect of the AT2 receptor antagonist PD 123319 on the contractile response to phenylephrine in aortic rings from SHR. To this end, we studied dose-response curves of phenylephrine (10(-9) to 10(-5) mol/L) in the presence and absence of losartan (10(-9), 10(-7), and 10(-5) mol/L) in SHR aortic rings. Preincubation with losartan reduced the constrictor response to phenylephrine but not to KCl (10 to 120 mmol/L) in a dose-dependent manner. On the other hand, the presence of captopril (10(-5) mol/L) in the incubation medium did not alter the response to phenylephrine, even at the dose of 10(-3) mol/L. The reduced response to phenylephrine in the presence of losartan was abolished in both endothelium-denuded rings and rings treated with a nitric oxide synthesis inhibitor. A similar situation was observed in PD 123319-pretreated rings, in which the effect of losartan on the contractile response to phenylephrine was reversed. Losartan was not able to stimulate the production of aortic cGMP compared with the control group. Likewise, losartan did not modify the relaxing responses to either acetylcholine or sodium nitroprusside in phenylephrine-preconstricted aortic rings. Furthermore, losartan did not alter isometric tension in aortic rings in either basal or phenylephrine-preconstricted conditions. These data demonstrate that Ang II potentiates the vasoconstriction induced by phenylephrine through the stimulation of AT1 receptors. Moreover, AT2 receptors and nitric oxide appear to be involved in this effect.

Diuretics in the treatment of hypertension. Part 1: thiazide and thiazide-like diuretics

Abstract: Introduction: Thiazides and thiazide-like diuretics inhibit the electroneutral Na+–Cl– cotransporter located on the apical membrane of the early segment of the distal convoluted tubule. They have been widely prescribed over 60 years in the treatment of hypertension and various edematous states. Areas covered: Thiazide diuretics reduce blood pressure (BP), although the mechanisms by which they chronically lower BP remain unknown. These drugs present a flat dose–response curve that explains why when prescribed at high doses their use was associated with a wide range of adverse effects, particularly electrolyte changes and metabolic abnormalities that can be minimized at the low doses actually prescribed. This article reviews the clinical pharmacology of thiazide diuretics to provide an insight into the mechanisms involved in their antihypertensive and adverse effects, the determinants of drug response and the possible differences in their pharmacodynamic and pharmacokinetic properties in an attempt to impro...

Nitric Oxide and Prostaglandins in the Prolonged Effects of Losartan and Ramipril in Hypertension

Abstract: We investigated the role of endogenous nitric oxide, kinins, and prostaglandins in the vasodepressor and renal excretory effects of the angiotensin II receptor antagonist losartan and the angiotensin-converting enzyme inhibitor ramipril administered for 1 week to spontaneously hypertensive rats. To this end, either losartan (10 mg/kg per day) or ramipril (2.5 mg/kg per day) was administered in drinking water with or without simultaneous administration of (1) the nitric oxide synthesis inhibitor N G -nitro-l-arginine methyl ester (L-NAME, 6 mg/kg per day), (2) the cyclooxygenase inhibitor indomethacin (5 mg/kg per day), (3) the bradykinin B 2 receptor antagonist Hoe 140 (0.5 mg/kg per day SC), or (4) L-NAME plus indomethacin. Both losartan and ramipril significantly reduced blood pressure as measured by the tail-cuff method. L-NAME increased blood pressure when administered solely or in combination with losartan. However, L-NAME attenuated the hypotensive effect of ramipril. Indomethacin did not affect blood pressure but it reduced the antihypertensive action of losartan and ramipril. Indomethacin administration did not potentiate the increase in blood pressure induced by L-NAME. However, the concurrent administration of both inhibitors almost totally blunted the vasodepressor action of ramipril. By contrast, losartan administration in the presence of L-NAME and indomethacin increased blood pressure to a level similar to that after losartan plus L-NAME. Hoe 140 did not modify either blood pressure or the hypotensive effects of losartan or ramipril. Increases in diuresis and water intake were observed during ramipril administration. Both effects were blunted only with the concurrent administration of L-NAME and indomethacin. None of the cotreatments were able to modify renal excretory function by themselves. These data suggest a contribution of endogenous nitric oxide and prostaglandins but not of kinins in the prolonged antihypertensive effect of both losartan and ramipril in the spontaneously hypertensive rat.

Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure

Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

Chronic kidney disease and the risks of death, cardiovascular events, and hospitalization

Abstract: Background End-stage renal disease substantially increases the risks of death, cardiovascular disease, and use of specialized health care, but the effects of less severe kidney dysfunction on these outcomes are less well defined. Methods We estimated the longitudinal glomerular filtration rate (GFR) among 1,120,295 adults within a large, integrated system of health care delivery in whom serum creatinine had been measured between 1996 and 2000 and who had not undergone dialysis or kidney transplantation. We examined the multivariable association between the estimated GFR and the risks of death, cardiovascular events, and hospitalization. Results The median follow-up was 2.84 years, the mean age was 52 years, and 55 percent of the group were women. After adjustment, the risk of death increased as the GFR decreased below 60 ml per minute per 1.73 m2 of body-surface area: the adjusted hazard ratio for death was 1.2 with an estimated GFR of 45 to 59 ml per minute per 1.73 m2 (95 percent confidence interval, 1....
