Brief Summary:
To examine the independent association of serum total homocysteine and C-reactive protein with arteriosclerotic cardiovascular disease morbidity and mortality
Detailed Description:
BACKGROUND
Patients with diabetic nephropathy experience markedly increased rates of morbidity and mortality due to arteriosclerotic cardiovascular disease CVD Established arteriosclerotic risk factors such as age sex cigarette smoking hypertension and dyslipidemia do not account adequately for this excess CVD risk Prospective data from general populations and much more limited findings from both diabetic cohorts and cohorts with chronic renal disease have linked elevated levels of total homocysteine tHcy and C-reactive protein CRP to arteriosclerotic CVD morbidity and mortality Determination of baseline serum total homocysteine and C-reactive protein concentrations in the Irbesartan Type 2 Diabetic Nephropathy Trial IDNT cohort affords a truly unique opportunity to evaluate the potential independent relationship between these putative CVD risk factors and subsequent CVD morbidity and mortality in this patient population The IDNT is a multicenter randomized double-blind placebo-controlled trial of 1715 hypertensive Type 2 diabetic patients aged 30 to 70 who have overt nephropathy 24 hour urinary protein excretion greater than 900 mg and a serum creatinine of 90 to 265 micromolsL The IDNT compares the effect of the angiotensin II receptor antagonist irbesartan with placebo and amlodipine on the progression of renal disease and mortality The IDNT is supported by Bristol-Myers Squibb Company in Princeton New Jersey and Sanofi-Synthelabo in Paris France
The study is in response to an initiative Ancillary Studies in Heart Lung and Blood Disease Trials released by the National Heart Lung and Blood Institute in June 2000
DESIGN NARRATIVE
The first specific aim is to conduct longitudinal analyses of the potential Independent relationship between baseline concentrations of serum total homocysteine and C-reactive protein in the full IDNT cohort and subsequentpooled cardiovascular disease morbidity and mortality primary analysis total mortality after multivariable -adjustment for the established predictors of cardiovascular disease morbidity mortality and total mortality The second specific aim is to conduct cross-sectional analyses to assess baseline serum total homocysteine and C-reactive protein concentrations in the full IDNT cohort in relation to potential baseline determinants of these analytes including B-vitamin status age and gender renal function indices ie both creatinine-based glomerular filtration rate estimates and proteinuria indices of glycemia prevalent cardiovascular disease CVD traditional CVD risk factors ie in particular smoking blood pressure and total cholesterolHDL cholesterol ratio
