From the Guidelines
For a CKD stage 4 patient with triglyceride levels above 330 mg/dL who is already on atorvastatin 80 mg, I recommend adding fenofibric acid (Trilipix) at a dose of 45-135 mg daily, with the lower dose preferred initially due to kidney impairment. Fenofibric acid is preferred over fenofibrate in CKD because it doesn't require renal activation and has less nephrotoxicity 1. Omega-3 fatty acids (icosapent ethyl 2-4 g daily or omega-3 ethyl esters 2-4 g daily) are also good options with minimal renal concerns, as suggested by the 2007 chronic angina focused update of the ACC/AHA guidelines 1. Some key points to consider when managing triglyceride levels in CKD patients include:
- Lifestyle modifications remain essential, including limiting simple carbohydrates, alcohol, and saturated fats while increasing physical activity as tolerated.
- Regular monitoring of kidney function, liver enzymes, and muscle symptoms is crucial when combining a statin with fibrate therapy due to increased risk of myopathy.
- If the patient develops muscle pain, weakness, or significant CK elevation, the fibrate should be discontinued immediately.
- Prescription-strength omega-3s are generally better tolerated than fibrates in CKD patients and may be considered as first-line add-on therapy if cardiovascular risk reduction is a primary goal. It's also important to note that the goal is to achieve non-HDL-C less than 130 mg per dL, and further reduction of non-HDL-C to less than 100 mg per dL is reasonable if triglycerides are 200 to 499 mg per dL, as stated in the 2007 focused update of the ACC/AHA/SCAI guidelines 1.
From the Research
Treatment Options for High Triglyceride Levels in CKD 4 Patients
- For a CKD 4 patient with triglyceride (TG) levels above 330 who is already on atorvastatin 80, additional treatment options may be considered to reduce TG levels and minimize cardiovascular risk 2, 3, 4, 5, 6.
- Fenofibrate, a fibrate, has been shown to lower TG levels and may be beneficial in patients with CKD, as it can delay the need for dialysis and reduce cardiovascular risk 4.
- Omega-3 fatty acids have also been found to reduce TG levels, and their combination with fenofibrate may result in a greater reduction in TG levels than fenofibrate alone 3.
- Ezetimibe, a non-statin lipid-lowering agent, can be prescribed in patients with CKD and may be used in combination with a statin to reduce cardiovascular outcomes 2, 6.
- The use of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, cholesterol-reducing nutraceuticals, bempedoic acid, and apabetalone in CKD patients with high TG levels requires further investigation 2, 6.
Considerations for CKD 4 Patients
- Patients with CKD 4 are at high risk of cardiovascular events, and lipid-lowering therapy should be initiated early and intensively to minimize this risk 2, 5.
- The choice of lipid-lowering agent should take into account the patient's renal function and the potential for drug interactions 2, 5.
- Regular monitoring of lipid profiles, renal function, and cardiovascular risk factors is essential in CKD 4 patients receiving lipid-lowering therapy 5.
