Type 2 diabetes (non-insulin-dependent diabetes mellitus, NIDDM) currently accounts for approximately 90% of all cases of diabetes. This figure is expected to more than double to nearly 300 million by the year 2025, with developing countries expected to experience the brunt of the increase with an expected 200% rise. Developed countries can expect to see a rise of 45% in rates of the disease. By the year 2004, it is estimated that up to 1 in 4 adults over age 45 will be diagnosed with diabetes. 1.

6 Diabeteses nephropathia (DNP)
Mind I. , mind II. tipusú diabetesben előfordul, lényegében ugyanaz a betegség, hasonló klinikummal és epidemiológiával Korábban a DNP „life-time” kockázata 30-45% volt, ez az utóbbi időben csökken, 15-25% A diabetes betegek 30%-ában a veseelégtelenség, ill proteinuria hátterében nem, vagy nem csak DNP áll Magyarországon a DM-ben szenvedők száma kb 1 millió

7 A diabeteses nephropathia epidemiológiája
I. tipusú diabetesben év alatt a DNP kockázata 5-10% II. tipusú diabetesben évente kb 2% vált diagnosztikus csoportot (microalbuminuria, macroalbuminuria, veseelégtelenség) II. tipusú diabetesben 150 mikromól körüli se kreat esetén a dialízisig átlagosan 2-3 év telik el

Functional changes • GFR GFR Structural changes Incipient nephropathy Proteinuria Rising serum creatinine Slide 9: Natural history of type 2 diabetic nephropathy: functional changes In contrast to type 1 diabetes, the time of onset of type 2 diabetes is often difficult to determine. Functional changes, exemplified by altered renal hemodynamics (renal vasodilatation, reduced renovascular resistance) and increased glomerular filtration rate (GFR), are present in the majority of patients at the time of onset of type 2 diabetes. Microalbuminuria may already be present at the time of diagnosis. 1. Nelson RG, Knowler WC, Mc Camnce DR, et al.

The JNC-V guidelines found that while as many as 90% of diabetic patients meet the criteria for hypertension, only 41% are currently on an antihypertensive therapy.1,2 Persistent microalbuminuria (> 300 µg/24 h or 200 mg/min) is the hallmark of diabetic nephropathy and its prevalence in diabetes is 25%. However, coexisting hypertension is associated with a doubling of the presence of microalbuminuria, left ventricular hypertrophy, electrocardiographic signs of myocardial ischemia and a prior history of overt cardiovascular events. MAU also advances the atherosclerotic process by 26 years.3-5 The prevalence of dyslipidemia in people with diabetes is as high as 40%. Its role in the development of atherosclerosis and macrovascular disease is well established. With its high prevalence in diabetic patients, 40%, and the increased risk of cardiovascular disease in this population, its importance in diabetes must be considered.6,7 1. Parving H-H, et al.

The beneficial impact from achieved control of systolic blood pressure (SBP) is demonstrated in this slide, which shows a meta-analysis of the 9 major clinical trials in diabetic and non-diabetic renal diseases. The GISEN Group, Klahr, and Moschio studies are those in non-diabetic subjects. The higher the SBP, the faster the GFR declines; the better the control of SBP, the slower the GFR declines.

Progression to nephropathy was defined as a doubling of serum creatinine concentrations in this study. The use of ACE inhibition reduced the overall risk for doubling serum creatinine by 48%. 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. 1. Lewis EJ, Hunsicker LG, Bain RP, et al.

Patients enrolled in this prospective, randomized, single-blind, placebo-controlled study had persistent albumin excretion rates (AER) of µg/min and normal renal function. The use of ACE inhibition decreased AER from 55 ± 33 to 20 ± 59 µg/min while those in the placebo group AER increased from 53 ± 31 to 85 ± 90 µg/min (geometric mean ± SD) at year five of the study. Within five years, 7.7% of the ACE inhibitor group and 23.5% of placebo-treated patients progressed to clinical albuminuria as defined by an AER of > 200 µg/min (p < 0.001). This is a risk reduction of 66.7% (p < 0.001) for ACE inhibitor-treated patients. AER increased at annual rate of 12.3% in the placebo group and declined at an annual rate of 16.7% for those treated by ACE inhibition (p < 0.001). 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. 1.

It examined the long-term renoprotective effects of ACE inhibition in type 2 diabetes. 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. When ACE inhibition treatment was discontinued, renewed progression of nephropathy occurred. The results of this study indicate the antiproteinuric and renoprotective effects of ACE inhibition in type 2 diabetic patients with early and moderately advanced diabetic nephropathy. 1.

30% 25% 20% 15% 10% 5% 0% 54%* % progressors Slide 23: Effect of ACE inhibition on other diabetic complications: diabetic retinopathy Diabetes is the leading cause of new blindness in adults years of age. Every year, up to 24,000 new cases of blindness due to diabetic retinopathy are diagnosed. 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 aimed to fill this gap by examining the effect of an ACE inhibitor on the progression of retinopathy. The EUCLID study is a 2 year, multicentre, randomized, controlled clinical trial of lisinopril versus placebo in patients with type 1 diabetes, with normo or microalbuminuria, aged years. In the placebo group, 26% were progressors while only 12% of those in the ACE I-treated group were progressors (p = 0.002). The risk of progression was therefore, 0.41 (95% CI, , p = 0.003) in the ACE I versus placebo group. 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. 1.

Two important secondary endpoints in IRMA 2 include change in overnight urinary albumin excretion rate (AER) and change in creatinine clearance. AER was reduced in the two irbesartan groups throughout the study (-24% and -38% at 24 months, compared with baseline, in the irbesartan 150 mg and 300 mg groups, respectively). AER remained unchanged in the control group (-2% at 24 months compared with baseline), p<0.001 for the comparison between the control group and the two irbesartan groups combined. Creatinine clearance remained in the normal range in all three groups throughout the study. 1 Parving et al, 2001a. Control (n=201) 150 mg (n=195) 300 mg (n=194) Irbesartan Parving H-H, et al.

Patients with microalbuminuria are negative for protein on usual dipstick testing and often have normal amounts of protein excreted on the 24-hour urine collections done for protein. However, these patients have abnormally elevated urinary albumin excretion at µg/min or mg/24 hours. 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. 1. Parving H-H, et al.

34 Diabetes + MAU MAU as a predictor of morbidity and mortality
Retinopathy Neuropathy Diabetes + MAU Left ventricular dysfunction Nephropathy Non-fatal cardiovascular disease Slide 11: MAU as a predictor of morbidity and mortality Microalbuminuria has been found to independently predict cardiovascular morbidity and all-cause mortality in essential hypertension and diabetes mellitus. 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. 1. Parving H-H. Microalbuminuria in essential hypertension and diabetes mellitus. J Hypertens 1996;14(suppl 2):S89-S94. All-cause mortality Peripheral/autonomic neuropathy Parving H-H.

10 8 6 4 2 10.02 6.52 Odds Ratio 3.20 2.32 Slide 12: MAU as a predictor of morbidity and mortality Microalbuminuria was found to be the leading independent predictor of coronary heart disease mortality (odds ratio of 10.02, 95% C.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 with other risk factors such as, arterial blood pressure, dyslipidemia, smoking habits and is a hallmark of vascular endothelial vulnerability. 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. 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. Of note is the superiority of ACE inhibitors over calcium channel blockers as to their respective effects on albuminuria (42% greater decrease). 1. Kasiske et al.

Due to their positive effects on microalbuminuria, recommendations suggest the use of ACE inhibitors as treatment for hypertensive and normotensive patients with microalbuminuria. 1.

The CARE patient population had a large group of patients with overt diabetes or impaired GTT in whom the effects of lipid lowering using pravastatin could be examined. The patient group contained 976 diabetics, 492 of whom received pravastatin (40 mg o.d.) and 484 of whom received placebo. The risk reduction for coronary events (CHD death, nonfatal MI, CABG or PTCA) in diabetic patients taking pravastatin as compared to placebo was 27% (p = 0.001; 7.0% to 42.9%). This is comparable to the risk reduction of 22% seen in non-diabetic patients (n = 3,183), indicating that diabetic patients with CHD and ‘normal’ cholesterol as well as those without diabetes can benefit from the cardioprotective effects of statins. 1.

39 Cardiovascular outcomes in primary prevention: Fosinopril Amlodipine Cardiovascular Event Trial (FACET) PROBE design with 380 type 2 diabetic patients with hypertension Follow-up time: 3.5 years Primary objectives: Serum lipids and diabetes control Secondary: Cardiovascular events: stroke, AMI, or hospitalised angina Blood pressure Renal function Slide 29: Cardiovascular outcomes in primary prevention: Fosinopril Amlodipine Cardiovascular Event Trial (FACET) FACET, the first of its kind, was a one-year trial compared fosinopril and amlodipine in 380 hypertensive diabetic patients. The study followed the PROBE design: prospective, randomized, open-label with blinded end points. A strict randomization procedure was used to allocate patients to different treatment regimens. Patients were randomized to receive fosinopril 20 mg/day (n = 189) or amlodipine 10 mg/day (n = 191). 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 monitored as secondary outcomes. The results were confirmed/validated by a blinded ad hoc committee using strict definitions of clinical outcomes to allow for an unbiased comparison of therapies and evaluation of the study results. 1.

Amlo n = 191 51%* % Probability Fos n = 189 Slide 31: FACET: probability of stroke, AMI, or hospitalised angina Despite similar blood pressure control, in FACET, fosinopril reduced the risk of having a cardiovascular event by 51% as compared with amlodipine (p = 0.03). 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 1.5 to 2 years and continued through the entire 3-5 year follow-up period. At the final visit, patients receiving fosinopril were 51% less likely to have experienced cardiovascular events compared with patients receiving amlodipine (p = 0.03). It is suggested that a benefit could be attributed to fosinopril rather than a risk induced by amlodipine. These findings have also been replicated in a similar trial, the ABCD trial, that compared an ACE I to a CCB. These results demonstrate the benefits of an ACE I, such as fosinopril, as optimal antihypertensive treatment in diabetic primary prevention of cardiovascular events. 1.
