The additional lowering of systolic and diastolic blood pressure by approximately 4-12 2-5 mmHg. The maximal antihypertensive effect was attained 4 weeks after the initiation of therapy, the first time point at which blood pressure was measured in these trials. In long-term follow-up studies without placebo control ; the effect of the combination of valsartan and hydrochlorothiazide appeared to be maintained for up to two years. The antihypertensive effect is independent of age or gender. The overall response to the combination was similar for black and non-black patients. There was essentially no change in heart rate in patients treated with the combination of valsartan and hydrochlorothiazide in controlled trials. Valsartan Valsartan inhibits the pressor effect of angiotensin II infusions. An oral dose of 80 mg inhibits the pressor effect by about 80% at peak with approximately 30% inhibition persisting for 24 hours. No information on the effect of larger doses is available. Removal of the negative feedback of angiotensin II causes a 2- to 3-fold rise in plasma renin and consequent rise in angiotensin II plasma concentration in hypertensive patients. Minimal decreases in plasma aldosterone were observed after administration of valsartan; very little effect on serum potassium was observed. In multiple-dose studies in hypertensive patients with stable renal insufficiency and patients with renovascular hypertension, valsartan had no clinically significant effects on glomerular filtration rate, filtration fraction, creatinine clearance, or renal plasma flow. In multiple-dose studies in hypertensive patients, valsartan had no notable effects on total cholesterol, fasting triglycerides, fasting serum glucose, or uric acid. The antihypertensive effects of valsartan were demonstrated principally in 7 placebo-controlled, 4- to 12-week trials one in patients over 65 ; of dosages from 10 to 320 mg day in patients with baseline diastolic blood pressures of 95-115. The studies allowed comparison of once-daily and twice-daily regimens of 160 mg day; comparison of peak and trough effects; comparison in pooled data ; of response by gender, age, and race; and evaluation of incremental effects of hydrochlorothiazide. Administration of valsartan to patients with essential hypertension results in a significant reduction of sitting, supine, and standing systolic and diastolic blood pressure, usually with little or no orthostatic change. In most patients, after administration of a single oral dose, onset of antihypertensive activity occurs at approximately 2 hours, and maximum reduction of blood pressure is achieved within 6 hours. The antihypertensive effect persists for 24 hours after dosing, but there is a decrease from peak effect at lower doses 40 mg ; presumably reflecting loss of inhibition of angiotensin II. At higher doses, however 160 mg ; , there is little difference in peak and trough effect. During repeated dosing, the reduction in blood pressure with any dose is substantially present within 2 weeks, and maximal reduction is generally attained after 4 weeks. In long-term follow-up studies without placebo control ; the effect of valsartan appeared to be maintained for up to two years. The antihypertensive effect is independent of. Co-amilozide.

Lithium: Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with angiotensin converting enzyme inhibitors. Very rare cases have also been reported with angiotensin II receptor antagonists. In addition, renal clearance of lithium is reduced by thiazides as a consequence the risk of lithium toxicity may be increased with PritorPlus. Co-administration of lithium and PritorPlus should only be allowed under strict medical supervision and should not be recommended. If this combination proves essential, serum lithium level monitoring is recommended during concomitant use. Medicinal products associated with potassium loss and hypokalaemia e.g. other kaliuretic diuretics, laxatives, corticosteroids, ACTH, amphotericin, carbenoxolone, penicillin G sodium, salicylic acid and derivatives ; : If these drugs are to be prescribed with the hydrochlorothiazide-telmisartan combination, monitoring of potassium plasma levels is advised. These medicinal products may potentiate the effect of hydrochlorothiazide on serum potassium see section 4.4 Special warnings and special precautions for use ; . Medicinal products that may increase potassium levels or induce hyperkalaemia e.g. ACE inhibitors, potassium-sparing diuretics, potassium supplements, salt substitutes containing potassium, cyclosporin or other medicinal products such as heparin sodium ; : If these medicinal products are to be prescribed with the hydrochlorothiazide-telmisartan combination, monitoring of potassium plasma levels is advised. Based on the experience with the use of other medicinal products that blunt the reninangiotensin system, concomitant use of the above medicinal products may lead to increases in serum potassium see section 4.4 Special warnings and special precautions for use ; . Medicinal products affected by serum potassium disturbances: Periodic monitoring of serum potassium and ECG is recommended when PritorPlus is administered with drugs affected by serum potassium disturbances e.g. digitalis glycosides, antiarrhythmics ; and the following torsades de pointes inducing drugs which include some antiarrhythmics ; , hypokalaemia being a predisposing factor to torsades de pointes. class Ia antiarrythmics e.g. quinidine, hydroquinidine, disopyramide ; class III antiarrythmics e.g. amiodarone, sotalol, dofetilide, ibutilide ; some antipsychotics : e.g. thioridazine, chlorpromazine, levomepromazine, trifluoperazine, cyamemazine, sulpiride, sultopride, amisulpride, tiapride, pimozide, haloperidol, droperidol ; others: e.g. bepridil, cisapride, diphemanil, erythromycin IV, halofantrin, mizolastin, pentamidine, sparfloxacine, terfenadine, vincamine IV. ; Digitalis glycosides: Thiazide-induced hypokalaemia or hypomagnesaemia favours the onset of digitalis-induced cardiac arrhythmias see 4.4 Special warnings and special precautions for use ; . Other antihypertensive agents: Telmisartan may increase the hypotensive effect of other antihypertensive agents.

Treated group to 162% and 132% in the indapamide and hydrochlorothiazide groups, respectively P: .001 ; . Discussion The results of the present study demonstrate that phenotypes of smooth muscle cells in both the aorta and coronary arteries of hypertensive SHRSP differ from those in WKY rats. The difference in phenotype is not identical in elastic and muscular vessels. However, in both types of vessels these changes are always indicative of a less mature phenotype, ie, the only expression of NM-myosin in the aorta and of both EIIIA fibronectin and NM-myosin in the coronary arteries. To our knowledge this is the first demonstration of a smooth muscle phenotypic shift in SHRSP. The two diuretic treatments, indapamide and hydrochlorothiazide, partially prevent the phenotypic shift independently of their effect on the hypertrophy of the media and despite the absence of a consistent lowering in blood pressure. The increase in vascular wall mass secondary to arterial hypertension results from two different mechanisms, hyperplasia and hypertrophy of smooth muscle cells. Cellular hyperplasia occurs in various resistance arteries and arterioles early during the development of hypertension, whereas cellular hypertrophy is observed at a later stage and is more prominent in the large elastic arteries eg, aorta ; . In the present study we show that the changes in gene expression clearly differ in the aorta and coronary vessels. In the aorta, NM-myosin is expressed by smooth muscle cells at the early stage of ontogeny or during the development of atherosclerosis.6'3-24 In the adult WKY rat, there remains a cell subpopulation with an immature phenotype within the aortic wall. Moreover, smooth muscle cells expressing either NM-myosin or EIIIA fibronectin seem to belong to two different cell populations, except in the inner part of the media. In the SHRSP, the.

Pharmacotherapeutic group: Angiotensin II antagonists and diuretics, ATC code: C09DA07 PritorPlus is a combination of an angiotensin II receptor antagonist, telmisartan, and a thiazide diuretic, hydrochlorothiazide. The combination of these ingredients has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone. PritorPlus once daily produces effective and smooth reductions in blood pressure across the therapeutic dose range. Telmisartan is an orally effective and specific angiotensin II receptor subtype 1 AT1 ; antagonist. Telmisartan displaces angiotensin II with very high affinity from its binding site at the AT1 receptor subtype, which is responsible for the known actions of angiotensin II. Telmisartan does not exhibit any partial agonist activity at the AT1 receptor. Telmisartan selectively binds the AT1 receptor. The binding is long-lasting. Telmisartan does not show affinity for other receptors, including AT2 and other less characterised AT receptors. The functional role of these receptors is not known, nor is the effect of their possible overstimulation by angiotensin II, whose levels are increased by telmisartan. Plasma aldosterone levels are decreased by telmisartan. Telmisartan does not inhibit human plasma renin or block ion channels. Telmisartan does not inhibit angiotensin converting enzyme kininase II ; , the enzyme which also degrades bradykinin. Therefore, it is not expected to potentiate bradykininmediated adverse effects. An 80 mg dose of telmisartan administered to healthy volunteers almost completely inhibits the angiotensin II evoked blood pressure increase. The inhibitory effect is maintained over 24 hours and still measurable up to 48 hours. After the first dose of telmisartan, the antihypertensive activity gradually becomes evident within 3 hours. The maximum reduction in blood pressure is generally attained 4-8 weeks after the start of treatment and is sustained during long-term therapy. The antihypertensive effect persists constantly over 24 hours after dosing and includes the last 4 hours before the next dose as shown by ambulatory blood pressure measurements. This is confirmed by measurements made at the point of maximum effect and immediately prior to the next dose through to peak ratios consistently above 80 % after doses of 40 and 80 mg of telmisartan in placebo controlled clinical studies ; . In patients with hypertension telmisartan reduces both systolic and diastolic blood pressure without affecting pulse rate. The antihypertensive efficacy of telmisartan is comparable to that of agents representative of other classes of antihypertensive medicinal products demonstrated in clinical trials comparing telmisartan to amlodipine, atenolol, enalapril, hydrochlorothiazide, and lisinopril ; . Upon abrupt cessation of treatment with telmisartan, blood pressure gradually returns to pre-treatment values over a period of several days without evidence of rebound hypertension. The incidence of dry cough was significantly lower in patients treated with telmisartan than in those given angiotensin converting enzyme inhibitors in clinical trials directly comparing the two antihypertensive treatments. The effects of telmisartan on mortality and cardiovascular morbidity are currently unknown. Hydrochlorothiazkde is a thiazide diuretic. The mechanism of the antihypertensive effect of thiazide diuretics is not fully known. Thiazides have an effect on the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium and chloride in approximately equivalent amounts. The diuretic action of hydrochlorothiazide reduces plasma volume, increases plasma renin activity, increases aldosterone secretion, with consequent increases in urinary potassium and bicarbonate loss, and decreases in serum potassium. Presumably through blockade of the reninangiotensin-aldosterone system, co-administration of telmisartan tends to reverse the potassium loss associated with these diuretics. With hydrochlorothiazide, onset of diuresis occurs in 2 hours, and peak effect occurs at about 4 hours, while the action persists for approximately 6-12 hours. Losartan potassium and hydrochlorothiazide administration had no effect on the reproductive performance or fertility in male rats at dosage levels of up to 135 mg kg day losartan in combination with 33.75 mg kg day hydrochlorothiazide. These dosage levels provided respective plasma concentrations AUC ; for losartan, the active metabolite and hydrochlorothiazide that were approximately 260-, 120-, and 50-fold greater than those achieved in man with 50 mg losartan potassium in combination with 12.5 mg hydrochlorothiazide. In female rats, however, the coadministration of losartan potassium and hydrochlorothiazide 10 2.5 mg kg day ; induced a slight but statistically significant decrease in fecundity and fertility indices. Compared to plasma concentrations in man see above ; these dosage levels provided respective increases in plasma concentration AUC ; for losartan, the active metabolite, and hydrochlorothiazide of approximately 15-, 4-, and 5-fold. There was no evidence of teratogenicity in rats or rabbits treated with losartan potassium and hydrochlorothiazide combination. Foetal toxicity in rats, as evidenced by a slight increase in supernumerary ribs in the F1 generation, was observed when females were treated prior to and throughout gestation. As observed in studies with losartan alone, adverse foetal and neonatal effects, including decreased bodyweight, mortality and or renal toxicity, also occurred when pregnant rats were treated with losartan potassium and hydrochlorothiazide combination during late gestation and or lactation. 6 6.1 PHARMACEUTICAL PARTICULARS List of excipients Tablet core: Microcrystalline cellulose Calcium hydrogen phosphate dihydrate Colloidal anhydrous silica Croscarmellose sodium Talc Magnesium stearate Tablet coating: Opadry 32K28708 white Hypromellose Lactose monohydrate Titanium dioxide E171 ; Glycerol triacetate 6.2 Incompatibilities Not applicable Shelf life 2 years.

It is clear that militarized tribes headed towards oligarchy over a conquered population ; , monarchy, or with growing trade to nationhood; those without weapons could survive only as guilds or castes. Both local and invading tribes like the later Rajputs ; were thus being absorbed into society, at different levels, some giving their name to an entire province. We attempted, by adding other drugs, to get similar blood pressure reductions among the groups, " said Dr Cushman, chief of preventive medicine at the Veterans Administration Medical Center, Memphis, Tennessee, and professor of preventive medicine and medicine, University of Tennessee. The calcium channel blocker was the next most effective agent at reducing SBP, and the ACE inhibitor was least effective in this regard; all 3 classes were similar at lowering DBP. In ALLHAT, few patients with systolic hypertension could be controlled on 1 drug, emphasized Dr Cushman. At 5 years, only about one fourth of patients had their SBP controlled 140 mm Hg ; on drug, and only about half could achieve the target SBP on 2 drugs. "With our current armamentarium, up to half of our patients [with elevated SBP] will need 3 or more drugs, as unfortunate as that may be, " he said. With the use of full doses of diuretics eg, 50 mg of hydrochlorothiazide ; , combinations of drugs that include a diuretic perform better at controlling both SBP and DBP, he said. In one study, combinations that included 50 mg of hydrochlorothiazide achieved SBP 140 mm Hg 77% of the time, compared with only 46% of the time when the combination did not include hydrochlorothiazide Figure 1 ; .4 The same principle applies to reducing pulse pressure, he added. "The first consideration, in my opinion, in the selection of antihypertensive drugs should almost always be which drugs or drug classes have most effectively reduced cardiovascular events, " he said. In the Systolic Hypertension in the Elderly Program SHEP ; 5 and the Systolic Hypertension in Europe Syst-Eur ; 6 trials, consistent benefits in patients with isolated systolic hypertension were obtained with treatment with a diuretic or calcium channel blocker compared with placebo. The treated groups, relative to placebo, had reductions in stroke of about 40% and in coronary heart disease of about 30%. There was a 50% reduction in heart failure with the diuretic-based therapy used in SHEP. Although neither trial was designed with mortality as an end point, both studies showed a reduction in mortality in the treated groups, as well as a reduction in overall cardiovascular disease events and metformin.

NDA 20-838 S-024 Page 6 Drug Interactions See PRECAUTIONS, Drug Interactions. Pharmacodynamics Candesartan inhibits the pressor effects of angiotensin II infusion in a dose-dependent manner. After 1 week of once daily dosing with 8 mg of candesartan cilexetil, the pressor effect was inhibited by approximately 90% at peak with approximately 50% inhibition persisting for 24 hours. Plasma concentrations of angiotensin I and angiotensin II, and plasma renin activity PRA ; , increased in a dose-dependent manner after single and repeated administration of candesartan cilexetil to healthy subjects, hypertensive, and heart failure patients. ACE activity was not altered in healthy subjects after repeated candesartan cilexetil administration. The once-daily administration of up to mg of candesartan cilexetil to healthy subjects did not influence plasma aldosterone concentrations, but a decrease in the plasma concentration of aldosterone was observed when 32 mg of candesartan cilexetil was administered to hypertensive patients. In spite of the effect of candesartan cilexetil on aldosterone secretion, very little effect on serum potassium was observed. Hypertension In multiple-dose studies with hypertensive patients, there were no clinically significant changes in metabolic function, including serum levels of total cholesterol, triglycerides, glucose, or uric acid. In a 12-week study of 161 patients with non-insulin-dependent type 2 ; diabetes mellitus and hypertension, there was no change in the level of HbA1c. Clinical Trials Hypertension The antihypertensive effects of ATACAND were examined in 14 placebo-controlled trials of 4- to 12weeks duration, primarily at daily doses of 2 to mg per day in patients with baseline diastolic blood pressures of 95 to 114 mm Hg. Most of the trials were of candesartan cilexetil as a single agent, but it was also studied as add-on to hydrochlorothiazide and amlodipine. These studies included a total of 2350 patients randomized to one of several doses of candesartan cilexetil and 1027 to placebo. Except for a study in diabetics, all studies showed significant effects, generally dose related, of 2 to 32 mg on trough 24 hour ; systolic and diastolic pressures compared to placebo, with doses of 8 to mg giving effects of about 8-12 4-8 mm Hg. There were no exaggerated first-dose effects in these patients. Most of the antihypertensive effect was seen within 2 weeks of initial dosing and the full effect in 4 weeks. With once-daily dosing, blood pressure effect was maintained over 24 hours, with trough to peak ratios of blood pressure effect generally over 80%. Candesartan cilexetil had an additional blood pressure lowering effect when added to hydrochlorothiazide. The antihypertensive effects of candesartan cilexetil and losartan potassium at their highest recommended doses administered once- daily were compared in two randomized, double-blind trials. In a total of 1268 patients with mild to moderate hypertension who were not receiving other antihypertensive therapy, candesartan cilexetil 32 mg lowered systolic and diastolic blood pressure by 2 to average more than losartan potassium 100 mg, when measured at the time of either peak or trough effect. The antihypertensive effects of twice daily dosing of either candesartan cilexetil or losartan potassium were not studied.

Whom obesity and related health problems are increasing at nearly double the rate in ethnic minorities compared with whites.232, 233 The rapid increase in the population of ethnic minorities in the United States is another factor that will lead to a rise in the prevalence of obesity and its complications unless effective, culturally diverse, population-based health promotion strategies are promoted. Prevention and Lifestyle Modifications for Overweight and Obesity The major goal of management of both the metabolic syndrome and overweight and obesity is to reduce the age-related rate of weight gain. This challenging task will require a complex combination of healthy behaviors, including decrease in sedentary activities, increase in physical activity, and reduction in calorie intake Table 16 ; . Simple yet practical suggestions include reducing time spent watching television or being online and increasing time spent walking or in activities that raise heart rate. The emphasis for weight management should be on avoidance of excess total energy intake and a regular pattern of physical activity. Reducing food portion sizes and limiting fat intake can assist in reducing overall calorie intake. High-sodium diets may be especially deleterious in obese subjects.234 Specific nutrient intakes for individuals should be based on lipoprotein levels, BP, and the presence of coexisting heart disease, diabetes, and other risk factors. For example, adoption of the well-studied low-sodium DASH eating plan94 provides heart-healthy foods that can be used to promote weight loss, reduce BP in both hypertensive and prehypertensive individuals, and reduce LDL. The benefits of modest lifestyle changes on cardiovascular risk factors are well documented. In the Framingham Heart Study, weight loss of 5 pounds or greater was associated with reductions in cardiovascular risk of about 40%.235 A 10% reduction in body weight can reduce disease risk factors.227 Physical activity is a key feature of treatment. Increased physical activity, when combined with a reduction in calories, is essential to weight loss success. Based on the available evidence, the recommendation is to engage in regular physical activity at least 30 minutes per day, most days of the week see Table 9 ; . In addition, physical activity is critical to the maintenance of weight loss and is important for overall reduction in cardiovascular risk; 60 to 90 minutes per week of walking can reduce CHD mortality by about 50%.236 The CVD benefits of slow walking appear to be comparable to those of walking more quickly, suggesting that the most and zestoretic.

Of the efforts. For example, our runner above would have a history of 20 mile years over ten years. Another runner who more recently took up the avocation and averaged five miles per day for the past three years would have a history of 15 mile years over three years. Such a notation may be of significance since it cannot escape notice that both of the marathon runners in the report who died of coronary artery disease had relatively recently converted to the sport.1 Certainly, no measuring stick can be perfect and this one is not. For example, if the data mile years over years ; were collected inappropriately, then errors would ensue. When gathered during a cocktail party, the history would undoubtedly be tainted with one mile year histories frequently turning into three or four mile year histories. On the other hand, if collected from runners just before a competitive run in the company of the other contestants, then a 300 mile year history may be reported as a 50 mile year history. No doubt one must be careful. Certainly, when questioning about cigarette smoking history for clinical information similar difficulties are ever-present, but they have not impaired the and prazosin.

Harmless. An antigen is defined as a substance capable of stimulating an immune response. ; So how do we get the body mind spirit to produce this immune response? Or moreover, how do we get it to produce a strong immune response to foreign substances, such as strep, flu, herpes, and others? The key, from a physiological point of view is to use very strong immunotherapy. Immunotherapy is defined as a treatment or prevention of disease by attempting to induce immunity. Thus, we can strengthen the immune system by inducing immunity through the use of substances which will prevent disease in the first place and lanoxin and Buy hydrochlorothiazide online.

MODURETIC provides diuretic and antihypertensive activity principally due to the hydrochlorothiazide component ; , while acting through the amiloride component to prevent the excessive potassium loss that may occur in patients receiving a thiazide diuretic. Due to its amiloride component, the urinary excretion of magnesium is less with MODURETIC than with a thiazide or loop diuretic used alone see PRECAUTIONS ; . The onset of the diuretic action of MODURETIC is within 1 to 2 hours and this action appears to be sustained for approximately 24 hours. Amiloride HCl: Amiloride HCl is a potassium-conserving antikaliuretic ; drug that possesses weak compared to the thiazide diuretics ; natriuretic, diuretic and antihypertensive activity. These effects have been partially additive to the effects of thiazide diuretics in some clinical studies. Amiloride HCl has potassium-conserving activity in patients receiving kaliuretic-diuretic agents. Amiloride HCl is not an aldosterone antagonist and the effects are seen even in the absence of aldosterone. Amiloride HCl exerts its potassium sparing effect through the inhibition of sodium reabsorption at the distal convoluted tubule, cortical collecting tubule and collecting duct; this decreases the net negative potential of the tubular lumen and reduces both potassium and hydrogen secretion and their subsequent excretion. This mechanism accounts in large part for the potassium sparing action of amiloride. Amiloride HCl usually begins to act within two hours after an oral dose. Its effect on electrolyte excretion reaches a peak between 6 and 10 hours and lasts about 24 hours. Peak plasma levels are obtained in 3 to hours and the plasma half-life varies from 6 to 9 hours. Effects on electrolytes increase with single doses of amiloride HCl up to approximately 15 mg. Amiloride HCl is not metabolised by the liver but is excreted unchanged by the kidneys. About 50 percent of a 20 mg dose of amiloride HCl is excreted in the urine and 40 percent in the stool within 72 hours. Amiloride HCl has little effect on glomerular filtration rate or renal blood flow. Because amiloride HCl is not metabolised by the liver, drug accumulation is not anticipated in patients with hepatic dysfunction, but accumulation can occur if the hepatorenal syndrome develops. Hydrochlorothiazide: The mechanism of the antihypertensive effect of thiazides is unknown. Hydrochlorothiazied does not usually affect normal blood pressure.
African television and radio stations are planning an on-air campaign to build hope in the face of the AIDS pandemic, in a bid to raise spirits on the worst-hit continent where millions have died from the disease. The aim is to restore confidence in young people who have developed a defeatist attitude toward a disease that kills 2 million people annually in sub-Saharan Africa, organizers said on Friday. "People in Africa are rather worn out by continuous negative ; AIDS messaging, " said Solly Mokoetle, chief operating officer of the South African and triamterene!

AGES OF PEAK BONE MASS IN DIFFERENT SKELETAL SITES IN THE NORMAL ADULT IRANIAN POPULATION.138 SERUM VITAMIN D AND RELATED PARAMETERS IN MASHHAD .139. The progression of left ventricular LV ; dysfunction towards overt chronic heart failure CHF ; after myocardial infarction MI ; is associated with progressive cardiac remodeling. Activation of the renin angiotensin aldosterone system RAAS ; plays a central role in this process, and blocking the RAAS with angiotensin-converting enzyme inhibitors ACE-I ; effectively reduces remodeling and prolongs survival after MI. Diuretics are often chronically added to ACE-I treatment to prevent fluid retention, although clinical trials to show their effect on mortality are lacking. On one hand, a diuretic-induced negative sodium balance generally elicits an optimal therapeutic effect of ACE inhibition1-3. On the other hand, diuretics may have adverse effects, i.e. electrolyte disturbances and renal function loss. We previously reported improved survival and cardiac function by add-on diuretic therapy with hydrochlorothiazide in rats with MI in the early chronic phase4. However, this survival benefit was not maintained during prolonged long-term follow-up 14 months ; . Addition of diuretic treatment to ACE inhibition may have adverse renal structural and functional effects, which may in turn affect long-term survival after MI, as poor renal function is strongly and independently associated with worsened long-term prognosis after MI5. Addition of a diuretic to ACE inhibition however may decrease renal function6. In the present study we investigated the long-term effects of adding a diuretic to ACE inhibition on renal morphology and function in relation to prognosis. We hypothesized that hydrochlorothiazide added to ACE inhibition in rats with myocardial infarction causes a sustained decrease in renal function and alterations in renal morphology, which is associated with worsened long-term survival.
