Screening Tools: egfr Considered the best overall index of kidney function. Moderately Normal GFR varies according to age, sex, and body size, and declines with age. reduced egfr=58ml/mi CKD-EPI Creatinine Equation (2009) to estimate GFR. kidney Other useful calculators related to kidney disease include MDRD and Cockroft Gault. n/1.73m function 2 GFR calculators are available online at www.kidney.org/gfr.
Screening Tools: ACR Urinary albumin-to-creatinine ratio (ACR) is calculated by dividing albumin concentration in milligrams by creatinine concentration in grams. Creatinine assists in adjusting albumin levels for varying urine concentrations, which allows for more accurate results versus albumin alone. 365mg/dL Spot urine albumin-to-creatinine ratio for quantification of proteinuria First morning void preferable 24hr urine test rarely necessary

Diabetic nephropathy A microvascular complication of diabetes marked by albuminuria and a deteriorating course from normal renal function to ESRD.
Diabetic Nephropathy Over 40% of new cases of endstage renal disease (ESRD) are attributed to diabetes. Incidence of ESRD Resulting from Primary Diseases (1998) 19% In 2001, 41,312 people with diabetes began treatment for endstage renal disease. In 2001, it cost $22.8 billion in public and private funds to treat patients with kidney failure. Minorities experience higher than average rates of nephropathy and kidney disease 3% 12% 23% 43% Diabetes Hypertension Glomerulonephritis Cystic Kidney Other Causes
Microalbuminuria Early indicator of diabetic nephropathy (diabetic damage to kidneys). This is the presence of small particles of protein in the urine. Passage of protein through the glomeruli (or filtering units of the kidney, damages the kidney.) -Detected in urinalysis (UA) -Presence of microalbuminuria indicates 16.5X increased risk of cardiovascular mortality over 3.6 years (Bell, 2009).
Epidemiology About 20-30% of patients with type I DM develop microalbuminuria, less than half progress to overt nephropathy Incidence of ESRD is 16% at 30 years. 5-60% of type II DM patients develop DN, depending on ethnicity
When diabetic retinopathy coexists with albuminuria, the likelihood of diabetic nephropathy is very high Suggests the presence of the specific pattern of nodular glomerulosclerosis, the so called Kimmelstiel-Wilson lesion
Pathophysiology Hyperglycaemia Glycation endproducts (AGE) Vasoactive systems Hemodynamic changes Proteinuria activation of signal transduction PKC, MAP kinase, NF-κB Growth factors Tubulointerstitial fibrosis Cell cycle changes Reactive oxygen radicals Renal failure Glomerulosclerosis
Pathogenesis Genetic predisposition to or protection from diabetic nephropathy Differences in prevalence of microalbuminuria, ESRD in different patient populations Only half of patients with poor glycemic control will develop diabetic nephropathy Multiple genes may be involved

Angiography and PCI: two in one? Although performing diagnostic and interventional procedures separately reduces the total volume exposure to contrast media, the risk of renal atheroembolic disease increases with multiple catheterizations. In CKD patients with diffuse atherosclerosis, a single invasive approach (diagnostic angiography followed by ad hoc PCI) may be considered, but only if the contrast volume can be maintained, 4 ml/kg. The risk of CIN increases significantly when the ratio of total contrast volume to GFR exceeds 3.7:1
