62 Year Old Male with High Cholesterol and Statin Intolerance Case Category:Familial Combined Hyperlipidemia; Primary Prevention History of present illness: 62 year old male with high cholesterol, prior statin intolerance and family history of diabetes.
Questions to Consider • Question 1: Very abnormal lipids and several secondary causes. New hypothyroidism and diabetes. What is his willingness to accept pharmacologic therapy? Address any barriers to treatment. • Question 2: Diet, salt, alcohol, carb, sugar intake? • Question 3: Previous statin trials? Which statin and what dose? • Has vitamin D deficiency been ruled out as cause of myalgias and previous statin intolerance?
Labs On no medications currently, oversynthesizing cholesterol in liver and candidate for statin, no evidence of hyperabsorption, previous intolerance to lipophilic statins (Simvastatin, Atorvastatin).

Initial Treatment & Management • Start Crestor 20 mg/day • Start Lovaza 1 g 1-4/day • Advise home blood pressure meter • Start Synthroid 50 mcg/day • Start Metformin ER 500 mg 2-3 tablets daily with slow titration as tolerated over the next few weeks • Start once daily injectable Liraglutide (Victoza) 6 mg/ml soln daily with gradual titration to 1.8 mg/ml • Advised low salt, low carb diet and daily exercise • Start Vitamin D3 5000 IU daily • Preventive care reminders with new diabetes diagnosis, ophthalmology, foot care, immunizations etc.
Follow Up • Familial Combined Hyperlipidemia – Improved; Started Crestor 20 mg, Metformin 2000 mg/day, Victoza 1.2 and Lovaza 4/day; LDL-P dropped from 2732 to 1433; Apo B normalized from 152 to 59; Total cholesterol dropped from 248 to 110, LDL-C from 157 to 53, triglycerides from 170 to 84 and non-HDL from 207 to 80. HDL is still low. • Diabetes – Improved; HbA1c lowered to 7.5 from 9.0; weight loss of 16 lbs; Continue therapy. • Hypothyroidism – Improved; Increase Synthroid to 75 mg/day. • Vitamin D Deficiency – Improved; Vitamin D level has increased from 26 to 52; Consider increasing if low energy.
Clinical Pearls Untreated diabetes will significantly impact LDL–P, Apo B and other lipids. Most diabetes therapies with the exception of Pioglitazone do not have published data on effect on lowering LDL-P/Apo B. Triglyceride reductions have been seen with Metformin, Pioglitazone, Cycloset, Exenatide, Liraglutide. In our clinical experience above therapies also improve small dense LDL-P.
