The overall relative risk for the development of proteinuria

for the three trials was 0.28 (95% CI: 0.15–0.53) with no significant heterogeneity between studies. No study provided information to allow assessment of regression to normoalbuminuria. The overall risk reduction was 4.5% giving a NNT of 22 patients per year to prevent one case of clinical proteinuria. The differences in BP between treatment and placebo were small and as such consider that a 72% drop in clinical proteinuria was unlikely to be caused by such a small difference and more likely that ACEi have a specific renoprotective effect.4 No appropriate trials were identified comparing antihypertensive agents and intensive versus moderate BP control other than the later analysis of the ABCD

Staurosporine ic50 trial. Intensive therapy with either enalapril or nisoldipine resulted in a lower percentage of people who progressed from normoalbuminuria and microalbuminuria to clinical proteinuria with no difference between the ACEi and CCB.73 Only one available placebo controlled study was identified for hypertensive people with type 2 diabetes with microalbuminuria.71 The treatment involved two dose levels of the ARB Roxadustat antagonist irbesartan for 2 years. A combined relative risk for clinical proteinuria for the ARB treatments was 0.50 (95% CI: 0.0.31–0.81). This reduction in the rate of progression to clinical proteinuria was independent of BP. Only the ABCD trial was identified as being relevant for comparing intensive versus moderate BP control in hypertensive people with type 2 diabetes with microalbuminuria.73 Individuals were randomized to either ACEi enalapril or the CCB antagonist nisoldipine. The percentage of people who progressed from Sclareol microalbuminuria to clinical proteinuria was not significantly different between the treatment groups. Newman et al.4 noted that the results supported the observations from the UKPDS of progression to clinical proteinuria among microalbuminuric and normoalbuminuric

people with type 2 diabetes was not affected by the level of BP control, however, separation of the two groups is not possible. Four trials were identified comparing different hypertensive agents in hypertensive people with type 2 diabetes with microalbuminuria.12,74–76 The trials all included an ACEi treatment compared with either a CCB antagonist or b blocker. The overall relative risk of development of clinical proteinuria for ACEi versus other hypertensive therapy was 0.74 (95% CI: 0.44–1.24) with no significant heterogeneity. Thus the ACEi reduced progression to clinical proteinuria as effectively as the other therapies. These findings were considered to be comparable with the UKPDS findings which could not separate normoalbuminuria from microalbuminuria. The two systematic reviews addressed the use of antihypertensive agents in people with diabetes with respect to renal outcomes.16,17 The objectives of the review by Strippoli et al.
