Older System: LDL-based goals New statin guidelines in 2013 LDL (mg/dL) Non-HDL (mg/dL) LDL to Consider • AHA/ACC guidelines Nov. 2013: Risk Category Primary target Secondary target Drug Therapy – assess risk of “hard” CV events Very High < 70 < 100 > 100 – used a new “global risk prediction score” High – recommend statins when 10-year risk is >7.5 % ³ 100 CHD or CHD Risk Equiv. < 100 < 130 (10-year risk > 20%) – consider statins when 10-year risk is 5 - 7.5% • Controversies: Moderately High ³ 130 < 130 < 160 ³ 2 Risk Factors < 100: optional < 130: optional 100–129: optional – do new guidelines mean there are many patients on (10-year risk 10-20%) statins who do not need to be? Moderate – do new guidelines mean many low risk patients not on ³ 2 Risk Factors ³ 160 < 130 < 160 statins should be initiated?

New Cholesterol Guidelines: Overview of New 2018 Guidelines Primary Prevention Consider many factors simultaneously • Focus on ASCVD risk, as well as certain numeric LDL targets • Differentiate who needs statin for ASCVD (secondary prevention) vs. who needs it for primary prevention • Differentiate high-intensity statin from moderate intensity statin •Screen for LDL>190 and diabetes •Calculate patient 10-year risk: is it >7.5%? •Consider several “risk enhancers” •Consider coronary artery calcium score Also include in discussion •Smoking cessation • Diet • HTN control • Exercise Grundy SM et al., 2018 JACC: 2018 AHA/ACC Grundy SM et al., 2018 JACC: 2018 AHA/ACC Guideline on the Management of Blood Cholesterol Guideline on the Management of Blood Cholesterol New Cholesterol Guidelines: Strength of Recommendations Secondary Prevention • Colors correspond to strength of recommendations Grundy SM et al., 2018 JACC: 2018 AHA/ACC Guideline on the Management of Blood Cholesterol

Statin Choices: a review Outline When using PI’s: ß PI’s NNRTI’s INSTI • Who should be on statins? Recent guidance can use, just reduce Most statins are Atorvastatin to 10-20mg metabolized by CYP3A4 system; • Practical use of statins in patients with HIV Lovastatin Pravastatin, – specific drug interactions with ARV’s pitavastatinarenot less potent • What can statins achieve? Protease inhibitors EFV: raises CYP3A4 cobicistat: Pravastatin use at lower doses inhibit/ activity reduces (use lowest dose with DRV, downregulate CYP3A4 – Lipid lowering , CV risk mitigation, malignancy reduction or just give atorvastatin) CYP3A4 to different Simvastatin degrees • What downside risks do statins pose? Ritonavir and – Myopathy, diabetes?, cognitive changes? cobicistat: most Fluvastatin PI’s à thus can EFV à can reduce statin • If statins don’t achieve their goals, or can’t be used, boost some statins levels to dangerous levels Rosuvastatin can us at 5-10mg, what can ARV switching do to improve lipids? and trigger Etravirine reduces fewer data in HIV+ rhabdomyolysis atorvastatin, • New drug class: PCSK9 inhibitors increases fluvastatin, no Pitavastatin change on pravastatin can us at 4mg dose Grundy: Update to NCEP ATPIII Guidelines Circulation, 2004 Statin potency in HIV+ patients Pitavastatin vs. Pravastatin • Retrospective study: 700 HIV+ patients, 2 large US clinics initiating statin • INTREPID Study: First double blind RCT of 2 statins in • Both atorvastatin and rosuvastatin did better than pravastatin in HIV+ population; first trial of pitavastatin reducing total cholesterol, LDL, TGs and non-HDL cholesterol • Randomized trial: 4mg daily pitavastatin vs. pravastatin 40mg daily • Less accumulated data with rosuvastatin limits its use • Inclusions: Age 18-70, on ART≥6mo., CD4>200, VL<200, • 4-week diet stabilization lead in; then advised lipid restricted diet throughout study • After this period: dyslipidemia: LDL 130-220 mg/dL and triglycerides ≤400 mg/dL • Exclusions: darunavir (due to pravastatin interaction), homozygous familial hypercholesterolemia, other secondary cause for hyperlipidemia, statin intolerance, diabetes, high fasting glucose, coronary artery disease Singh et al., Clin.
