  • Hyperlipidemia is common among kidney transplant recipients. 1 This includes increased levels of the particularly atherogenic lipoprotein (a) and small, dense, low-density lipoprotein cholesterol (LDL-C). 2 Serum cholesterol levels have been shown to be an independent risk factor for graft failure and patient mortality as well as CVD. The National Kidney Foundation Task Force on Cardiovascular Disease recommends that kidney transplant recipients should be considered to be in the highest category of CVD risk, when applying the National Cholesterol Education Program guidelines for the treatment of dyslipidemias. 1.

    4. 4. What are CHD Risk Equivalents Diabetes Chronic Kidney Disease Other clinical forms of atherosclerotic disease: – Peripheral arterial disease (PAD) – Abdominal aortic aneurysm (AAA) – Carotid artery disease Multiple ( single or total) risk factors that confer a 10-year risk for CHD > 20% NCEP ATP III RECOMMENDATIONS JAMA 2001; 285
    5. 5. ATP III Recommendations• Treatment should be started if LDL: – >100 mg/dL for CHD or CHD equivalent (10-year risk > 20%) – >130 mg/dL for 2+ risk factors (10-year risk 10-20%) – >160 mg/dL for 0-1 risk factor (10-year risk < 10%) NCEP ATP III RECOMMENDATIONS JAMA 2001; 285
    6. 6. WHY?• LEFT VENTRICULAR HYPERTROPHY: – Eccentric: fluid retention,anemia,AVF – Concentric: HTN,Aortic valvular disease• ATHEROSCLEROSIS: – Occlussive vascular, Ischemic Heart Disease and Increased Calcium deposition• ARTERIOSCLEROSIS: – Loss of elasticity of the Aorta and large vessels

    10. 10. Dyslipidemia and CKD facts Chronic Kidney Disease patients have 10-100 increased incidence of death due to cardiovascular complications compared with the general population. Foley et al., Am. Journal Kidney Diseases 1998; 32
    11. 11. Chronic Kidney Disease in the US STAGE GFR Prevalence Prevalence (ml/min/1.732) (%) 1 ~ 90 5,900,000 3.3 2 60-89 5,300,000 3.0 3 30-59 7,600,000 4.3 4 15-29 400,000 0.2 5 <15 or 300,000 0.1 dialysis CKD Guidelines. Am J Kidney Diseases 2002; 39 Suppl. 1
    12. 12. GENERAL CONCEPTS• Chronic Kidney Disease in the US: – 20 MILLION patients with CKD – Defined as a sustained GFR < 60 ml/min/1.73 m2 or patients with microalbuminuria of > 30 mg/dayCardiovascular disease is a modifiable risk factor• In CKD : – low cholesterol is associated with increased mortality – Statins can decrease –Δ GFR and decrease the CRP
    13. 13. GENERAL CONCEPTS II• Chronic Kidney Disease patients (CKD) lipid panel is characterized: – Decrease level of Apo A I + II leading to LOW levels of HDL – Increased level of Apo B leading to HIGH levels of LDL and VLDL WHY DECREASED LIPOLYTIC ENZYMES, POOR APOPROTEIN BINDING CAPACITY AND DECREASED UPTAKE OF LIPOPROTEINS
    14. 14. CKD and Cardiovascular Disease • Traditional risk • Non Traditional risk factors: factors: – Diabetes mellitus – Inflammation – Dyslipidemia – Oxidative stress – Hypertension – Malnutrition – Proteinuria – Anemia – Volume excess Framingham – Abnormal Ca/P – HyperhomocysteinemiaSarnak M J, et al. Cardiovascular disease and chronic renal disease:a new paradigm. Am J Kidney Dis. 2000;35 (4 suppl 1)
    15. 15. Lipids characteristics on CKD• General population- increased LDL• CKD patients: No correlation with LDL• Increased Lipoprotein a Lp (a) in CKD• Hemodialysis patients have a decreased catabolic rate for Lp (a)• Lp(a) and Apoprotein a are not well treated by statins.

    19. 19. REACTIVE OXIDATIVE SPECIES (ROS) • Increased production of ROS at the endothelium- Increased LDL oxidation • Oxidized LDL molecule is taken by macrophages leading to foam cells and calcification of the vessels • ROS inactivate nitric oxide: – Promoting pro-atherogenic events: • Increased WBC adherence • Platelet aggregation • Increasing CRPNiwa et al.

    25. 25. Therapy for Dyslipidemia• Are the STATINS effective and safe to treat Dyslipidemia among CKD patients?• Can we impact CARDIOVASCULAR mortality among CKD patients?• Other benefits of STATINS beyond Cholesterol control?
    26. 26. Potential Renoprotective Effects of Statins • Have been shown to provide pleiotropic effects independent of their proven beneficial effect on lowering cholesterol levels1 • Anti-inflammatory effects may be useful for the management of glomerulonephritis and diabetes mellitus • May have a potential immunomodulatory role in organ transplant recipients2 • Have been shown to enhance endothelial function2 • Have antioxidant effects21.

    29. 29. TREATMENT OVERVIEW cont.• FIBRATES: – Used to treat TG reducing by 30-50% – Fibrates are renal excreted – Increased risk of Rhabdomyolysis with statins – Increase serum creatinine• NICOTINIC ACID: – Most efficacious increasing HDL-C – No studies in CKD patients• BILE ACID SEQUESTRANTS: – Block intestinal reabsorption of bile acid and LDL-C
    30. 30. PHARMACOLOGY & SAFETY
    31. 31. PHARMACOLOGY & SAFETY cont• Most statins are metabolized by the liver.• Get a baseline CPK• Myalgias: check CPK and hold the statin • Restart at 50% of the dose or use another • Consider use CoQ 10 • Do not use in patients with acute or chronic liver disease • Be careful with Calcineurin Inhibitors, warfarin, grapefruit juice
