To investigate whether a low dose of the angiotensin converting enzyme (ACE) inhibitor ramipril lowers cardiovascular and renal events in patients with type 2 diabetes who have microalbuminuria or proteinuria.
Randomised, double blind, parallel group trial comparing ramipril (1.25 mg/day) with placebo (on top of usual treatment) for cardiovascular and renal outcomes for at least three years.
Multicentre, primary care study conducted mostly by general practitioners in 16 European and north African countries.
4912 patients with type 2 diabetes aged >50 years who use oral antidiabetic drugs and have persistent microalbuminuria or proteinuria (urinary albumin excretion > or = 20 mg/l in two consecutive samples), and serum creatinine < or = 150 micromol/l.
The primary outcome measure was the combined incidence of cardiovascular death, non-fatal myocardial infarction, stroke, heart failure leading to hospital admission, and end stage renal failure.
Participants were followed for 3 to 6 (median 4) years. There were 362 primary events among the 2443 participants taking ramipril (37.8 per 1000 patient years) and 377 events among the 2469 participants taking placebo (38.8 per 1000 patient years; hazard ratio 1.03 (95% confidence interval 0.89 to 1.20, P = 0.65)). None of the components of the primary outcome was reduced. Ramipril lowered systolic and diastolic blood pressures (by 2.43 and 1.06 mm Hg respectively after two years) and favoured regression from microalbuminuria (20-200 mg/l) or proteinuria (> 200mg/l) to normal level (< 20 mg/l) or microalbuminuria (P < 0.07) in 1868 participants who completed the study.
Low dose (1.25 mg) ramipril once daily has no effect on cardiovascular and renal outcomes of patients with type 2 diabetes and albuminuria, despite a slight decrease in blood pressure and urinary albumin. The cardiovascular benefits of a daily higher dose (10 mg) ramipril observed elsewhere are not found with an eightfold lower daily dose.

    • "The trial was a four-year, double-blind, parallel study. This trial showed no effect of low dose ramipril on the incidence of renal events [27]. The French Caucasian participants (3137 of the 4912 subjects) gave written informed consent for enrollment in the genetic sub-study. "

    ABSTRACT: Sterols, bile acids and their receptors have been involved in diabetic nephropathy. The ATP-binding cassette transporters G5 and G8 (ABCG5 and ABCG8) play an important role in intestinal sterol absorption and bile acid secretion. The aim of our study was to assess the associations between two ABCG8 coding polymorphisms, T400K and D19H, and the incidence of renal events in type 2 diabetic subjects. Participants were the 3137 French type 2 diabetic subjects with micro- or macro-albuminuria from the genetic substudy of the DIABHYCAR trial. The mean duration of follow-up was 4years. Renal events were defined as a doubling of serum creatinine concentration or end-stage renal disease at follow-up. We then used a second population (DIAB2NEPHROGENE) of 2140 type 2 diabetic patients for the purpose of validation. In DIABHYCAR, the 400K allele was significantly associated with a higher risk of incident renal events in a multiple adjusted model (HR: 1.75 [95% CI 1.20-2.56], P=0.003). This association was still significant after further adjustments for baseline values of estimated glomerular filtration rate and urinary albumin excretion. In the validation population, the 400K allele was associated with the prevalence of end-stage renal disease (OR=2.01 [95% CI 1.15-3.54], P=0.015). No significant association was found between the D19H polymorphism and the risk of diabetic nephropathy. A polymorphism of the sterol transporter ABCG8 has been associated with the prevalence of end-stage renal disease and with the incidence of new renal events in type 2 diabetic patients.

    • "Increased levels of urinary albumin excretion (UAE) do not only provide an indication of early renal dysfunction, but functions also as a marker of endothelial dysfunction [3]. Many trials have reported on a high prevalence of elevated UAE not only in high risk subjects suffering from diabetes [4] [5], renal failure [6], or heart failure [7] [8], but also in subjects from the general population [9]. An increased UAE was in every cohort associated with worse outcome. "

    ABSTRACT: Background The PREVEND IT trial reported on a high cardiovascular (CV) event rate in subjects with a baseline urinary albumin excretion (UAE) rate of ≥ 50 mg/24 h. Here, we report on the observed 10-year CV outcome of this population and compare this with the predicted Framingham Risk Score (FRS). In addition, we evaluated the effect of four years of fosinopril treatment on this relation. Methods and results From the PREVEND IT cohort, 833 subjects without history of CV disease, randomized to fosinopril (N = 412) or placebo (N = 421), were studied. The primary endpoint included CV mortality and adjudicated hospitalization for CV disease during a 10-year follow-up period. Mean age was 51 ± 12 years and 65% were males, while prevalence of diabetes (2.6%) and use of CV drugs (3.5%) was low. Subjects were categorized to high UAE (≥ 50 mg/24 h) or low UAE (< 50 mg/24 h). After 10 years of follow-up, the event rate in the high UAE group was almost twice as high as predicted by the FRS (29.5% vs. 17.2%). Treatment for four years with fosinopril reduced the event rate to comparable levels of that predicted by FRS. The addition of UAE ≥ 50 mg/24 h to the FRS improved the Integrated Discrimination Improvement (P = 0.033) and increased the area under the curve by 0.54% (P = 0.024). Conclusions The 10-year CV risk of subjects with an elevated UAE (≥ 50 mg/24 h) is substantially underestimated by the FRS. Treatment with fosinopril successfully reduced this increased event rate to FRS-predicted CV risk.

    ABSTRACT: Stroke is the leading cause of serious long-term disability and the third leading cause of death in the Western world. In patients with chronic kidney disease (CKD), stroke and vascular dementia are significantly more prevalent than in the general population. However, the optimal stroke prevention strategy in these patients is unclear, because controlled studies are scarce. In this paper, the results of the major antihypertensive trials and meta-analyses for stroke prevention in the general high cardiovascular (CV) risk population and in the CKD population are reviewed. The risk of stroke is much more blood pressure (BP)-dependent than the risk of other CV events, and, consistently, risk reduction is also strongly dependent on BP reduction. The magnitude of BP lowering is crucial in both populations. In renal patients, diuretics alone or in combination with angiotensin-converting enzyme (ACE) inhibitors, compared with placebo, are powerful BP-lowering and stroke-protective agents. Calcium channel blockers and ACE inhibitors also seem to be superior to placebo, but with more modest BP-decreasing effects and statistically nonsignificant reductions in stroke risk. In active versus active drug studies, independently of the BP-lowering effect, there are no significant advantages of any class over the others, although the results point to a slight superiority of diuretics and calcium channel blockers. Antihypertensive regimens in CKD patients should always include a diuretic, because, in the pathogenesis of CKD-associated hypertension, volume overload plays a crucial role. Diuretics are also inexpensive and well tolerated. We suggest that further studies of CV outcomes in CKD patients should compare various combinations of diuretics plus other drugs, such as calcium channel blockers, ACE inhibitors and angiotensin II receptor blockers.
