How to manage a patient with hypertriglyceridemia, impaired renal function, vitamin D deficiency, and hyperglycemia, who is on multiple medications and refuses statin therapy due to muscle soreness?

Management of Hypertriglyceridemia in a Patient with CKD, Vitamin D Deficiency, and Statin Intolerance

For this patient with hypertriglyceridemia, CKD stage 3b, and statin intolerance, fenofibrate therapy should be initiated at a reduced dose of 54 mg daily due to impaired renal function, alongside continued metformin for glycemic control and lifestyle modifications.

Patient Assessment

• The patient presents with multiple cardiovascular risk factors including:
  • Hypertriglyceridemia (236 mg/dL) 1
  • Type 2 diabetes (HbA1c 6.5%, glucose 115 mg/dL) 1
  • Stage 3b CKD (eGFR 34 mL/min/1.73m²) 1
  • Vitamin D deficiency 2
  • Coronary artery disease with angina 1
  • Statin intolerance due to muscle soreness 1

Management Strategy for Hypertriglyceridemia

Pharmacological Approach

• Fenofibrate therapy is indicated for this patient with triglycerides ≥200 mg/dL 1

  • Start with reduced dose of 54 mg daily due to moderate renal impairment 3
  • Monitor renal function and lipid levels before increasing dose 3
  • Avoid fenofibrate in severe renal impairment, but it can be used cautiously in moderate impairment 3

• Continue metformin for glycemic control, which will also help reduce triglycerides 1, 4

  • Current dose of 500 mg is appropriate given the patient's renal function
  • Improved glycemic control is a first-line approach for triglyceride management 1

Addressing Statin Intolerance

• Evaluate vitamin D status and correct deficiency 1, 5

  • Vitamin D deficiency can contribute to statin-associated muscle symptoms 5
  • Continue ergocalciferol supplementation as prescribed

• Consider statin rechallenge after vitamin D repletion 1, 5

  • Try a different statin at low dose (e.g., rosuvastatin 5 mg or atorvastatin 10 mg)
  • Consider alternate-day or once/twice weekly dosing regimen 1
  • If still not tolerated, continue with ezetimibe alone (already prescribed) 1

Non-Pharmacological Interventions

• Dietary modifications 1

  • Reduce saturated fat intake to <7% of total calories 1
  • Limit trans fatty acids to <1% of total calories 1
  • Restrict cholesterol to <200 mg/day 1
  • Moderate alcohol consumption 1

• Physical activity 1

  • Encourage 30-60 minutes of moderate-intensity activity at least 5 days per week 1
  • Incorporate resistance training at least 2 days per week 1

• Weight management 1

  • Set target BMI of 18.5-24.9 kg/m² 1
  • Target waist circumference <35 inches for women or <40 inches for men 1

Monitoring Plan

• Lipid profile 1

  • Check 8 (±4) weeks after starting fenofibrate 1
  • After adjustment, recheck until target levels achieved 1
  • Once at target, monitor annually 1

• Renal function 3, 6

  • Monitor creatinine and eGFR every 3 months due to CKD and fenofibrate therapy 3
  • CKD patients with hypertriglyceridemia have increased cardiovascular risk 6, 7

• Muscle symptoms 1

  • Assess for muscle pain, tenderness, or weakness at each visit 1
  • If symptoms develop, check CK levels 1
  • If CK >10x ULN or severe symptoms occur, discontinue fenofibrate 1

• Glycemic control 1, 4

  • Monitor HbA1c every 3 months 1
  • Adjust metformin as needed based on renal function and glycemic control 1

• Vitamin D levels 5, 2

  • Recheck after 3 months of supplementation 2
  • Vitamin D deficiency is associated with increased metabolic syndrome risk in CKD patients 2

Special Considerations for This Patient

• Renal impairment requires caution with fenofibrate dosing 3, 6

  • CKD alters lipid metabolism, leading to hypertriglyceridemia primarily through decreased catabolism 6, 7
  • Monitor for worsening renal function with fenofibrate therapy 3

• Diabetes and CKD create complex dyslipidemia 8, 4

  • Combination leads to more severe lipid abnormalities 8, 4
  • Focus on both glycemic control and direct lipid management 1, 4

• Vitamin D deficiency may contribute to metabolic syndrome 2

  • Correction may improve lipid parameters and muscle symptoms 5, 2
  • Continue prescribed ergocalciferol supplementation 2
