A legújabb sokszeletes spirál-CT-kkel a képalkotás másodpercek alatt elvégezhető, ami a jelentős sugárterheléssel járó vizsgálatok számának drámai növekedéséhez vezetett, gyermekkorban is. Ugyanakkor nem feledkezhetünk meg arról, hogy az elmúlt években jelentős fejlődés történt az ultrahang-technológiában, a képminőség egyre jobb. A gyermekek ideális alanyai a vizsgálatnak, miután az esetek nagy részében testtömegük kisebb, kevesebb zsírt tartalmaz, így könnyen vizsgálhatók magas frekvenciájú transzducerrel, aminek következtében sokkal részletgazdagabb, jobb felbontású képek nyerhetők, mint általában felnőtteknél. Megfelelő készülék és gyakorlott, gyermekradiológiában tapasztalt vizsgáló esetében csaknem valamennyi testtájék vizsgálható, mindenképpen első választandó módszer, amely legtöbbször elegendő esetleg röntgenvizsgálattal kiegészítve a megfelelő diagnózis felállítására. A közlemény azokkal a lehetőségekkel foglalkozik, ahol a modern ultrahangkészülékek birtokában az ultrahangvizsgálat elegendő a pontos diagnózishoz.

Ennek haemodynamicai magyarázata főképp az, hogy az egyes nephronokban a vas efferens mérsékelt szűkülete, a vas afferens tágulata jön létre, ezáltal megnő az intraglomerularis nyomás és az ultrafiltratum mennyisége. A fokozott filtratio és glomerulus permeabilitás következtében megnövekszik a filtrált és ürített albumin mennyisége is. Mindez a glomerulus basalmembrán és endothel között elhelyezkedő mesangialis matrix kóros felhalmozódásához vezet, aminek végeredménye a glomerulosclerosis, a következményes, lassú glomerulus pusztulás. E fokozott ultrafiltratum, albuminexcretio, mesangialis matrix képződésében biztosan jelentős szerepet játszik a renalis renin-angiotensin RAS rendszer aktiválódása is. Nyilvánvaló az is, hogy az esetleg jelenlévő systemás vérnyomásemelkedéssel együtt járó intraglomerularis nyomásfokozódás tovább ronthatja a fenti állapotot.

ACE inhibition also reduced the risk of clinical events such as death, need for dialysis, or transplant by half as compared with placebo.

Furthermore, ACE inhibition protected against deterioration in type 1 diabetic nephropathy to a greater degree than would be expected from blood pressure reduction alone. This slide and the next 2 slides focus on the positive effects of ACE inhibition in patients with type 1 and 2 diabetes.

This is a risk reduction of AER increased at annual rate of Following five years of therapy with an ACE inhibitor, normotensive patients with type 2 diabetes experienced significantly less progression of microalbuminuria to clinical albuminuria and reduced AER when compared to placebo.

ACE inhibition was found to offer long-term protection against the development of nephropathy in normotensive type 2 diabetic patients with microalbuminuria. It was also found to stabilize renal function in previously untreated patients with impaired renal function.

All patients with type 1 diabetes for longer than 5 years and all patients with type 2 diabetes within 6 months of diagnosis, should be examined by an ophthalmologist. While several studies have evaluated the effects of ACE inhibitors on diabetic nephropathy, less focus has been placed on their effects on retinopathy.

The EUCLID study is a 2 year, multicentre, randomized, controlled clinical trial of lisinopril versus placebo in patients with type stages of diabetic nephropathy diabetes, with normo or microalbuminuria, aged years.

The risk of progression was therefore, 0. ACE inhibitors appear to have beneficial effects on diabetic retinopathy, even in patients with little or no renal disease and minimal retinopathy that cannot be fully accounted for by effects on blood pressure. The effect of lisinopril on retinopathy in people with insulin dependent diabetes mellitus IDDM. Diabetologia ;40 suppl 1 :A The Euclid Study Group. Diabetologia ;40 suppl 1 : A Two important secondary endpoints in IRMA 2 include change in overnight urinary albumin excretion rate AER and change in creatinine clearance.

Creatinine clearance remained in the múmia a diabetes kezelésében 2 range in all three groups throughout the study. Lancet ; Patients with microalbuminuria are negative for protein on usual dipstick testing and often have normal amounts of protein excreted on the hour urine collections done for protein.

Many patients with microalbuminuria go on to develop overt nephropathy, However, once a patient has overt proteinuria there is no reason to measure urinary albumin excretion, as a test for proteinuria is already positive.

The goal is to identify nephropathy and MAU in the early stages, and to institute treatment before it is too late. J Hypertens ;14 suppl 4 :SS Parving H-H. Microalbuminuria is associated with numerous complications, cardiovascular disease risk factors and also factors such as hyperinsulinemia, insulin resistance and dyslipoproteinemia.

As well, patients with microalbuminuria also show an increased incidence of left ventricular hypertrophy LVH and retinal microvascular lesions. While the connection between microalbuminuria and death from cardiovascular disease is not yet clear, several theories have been postulated. One such theory is that as microalbuminuria is a marker of widespread endothelial dysfunction, the link may be the opportunity for increased penetration of atherogenic lipoprotein particles in the arterial wall, which is a marker of established cardiovascular disease.

Microalbuminuria in essential hypertension and diabetes mellitus. I, in a multivariate analysis. Microalbuminuria was followed by smoking, diastolic blood pressure and serum cholesterol as primary predictors of CHD mortality. Microalbuminuria is a potent, independent risk factor for total and cardiovascular mortality. It also interacts stages of diabetic nephropathy other risk factors such as, arterial blood pressure, dyslipidemia, smoking habits and is a hallmark of vascular endothelial stages of diabetic nephropathy.

It is thought that perhaps the increase in vascular vulnerability leads to increased permeability to atherogenic lipoprotein particles in the arterial wall in diabetic patients, and may account for the increased rate of cardiovascular disease in this population. The impact of cardiovascular disease on people with diabetes: the potential for prevention. Lancet ; suppl 1 In fact, ACE inhibitors were associated with reductions in proteinuria and albuminuria and improvements in glomerular filtration rates which were independent of blood pressure changes.

Összefoglalás Az elmúlt években a fejlett országokhoz hasonlóan hazánkban is rohamosan nőtt a dializált betegek között a diabeteszes betegek száma, ezen belül is a 2-es típusú diabeteszeseké. A 2-es típusú diabetesben azonban a vesekárosodást a cukorbetegségen kívül vagy mellett a hypertonia, az atherosclerosis, a gyakori húgyúti infekciók is létrehozhatják, de nem ritka az egyidejű glomerulonephritisek előfordulása sem. Sokszor nehezen eldönthető, hogy a beteg proteinuriájának, beszűkült vesefunkcióinak hátterében milyen patológiai elváltozás ok áll nak ; a proteinuria kimutatása 2-es típusú diabetesben nem jelenti szükségszerűen a diabeteszes nephropathia diagnózisát. A cikkben a szerzők összefoglalják a 2-es típusú diabetesben előforduló veseelváltozások differenciáldiagnosztikáját, a kivizsgálás legfőbb szempontjait, a vesebiopszia indikációját.

Circulation ;94 8 suppl A strict randomization procedure was used to allocate patients to different treatment regimens. Should blood pressure not be controlled, the other study drug was added to either regimen. The PROBE design is gaining popularity as it effectively creates a clinical experience and is currently regarded as equal to double-blind randomized trials in regard to randomization.

The primary end point was to assess treatment related differences in serum lipids and diabetes control.

Predefined cardiovascular disease events, blood pressure control, and renal function were also stages of diabetic nephropathy as secondary outcomes. Tatti et al, Diabetes Care April, Tatti P, et al. Diabetes Care April, Prespecified cardiovascular events included fatal and nonfatal myocardial infarction, fatal and nonfatal stroke, and hospitalised angina. The beneficial effect of fosinopril over amlodipine became apparent within 1.

It is suggested that a benefit could be attributed to fosinopril rather than a risk induced by amlodipine. These results demonstrate the benefits of an ACE I, such as fosinopril, as optimal antihypertensive treatment in diabetic primary prevention of cardiovascular events.
