From the Guidelines
Treatment for severe hypertriglyceridemia should prioritize lifestyle modifications, including dietary changes and weight loss, alongside medications such as fibrates and omega-3 fatty acids to reduce triglyceride levels and minimize the risk of pancreatitis and cardiovascular disease. When managing severe hypertriglyceridemia, it's crucial to consider the patient's overall cardiovascular risk profile, including factors such as diabetes, obesity, and liver dysfunction, as highlighted in the guidelines by the Endocrine Society 1. The primary goal is to reduce triglyceride levels below 500 mg/dL to decrease the risk of acute pancreatitis, a potentially life-threatening condition associated with severe hypertriglyceridemia 1. Key lifestyle modifications include:
- Restricting fat intake, with recommendations varying from 10% to 25% of total calories depending on the severity of hypertriglyceridemia 1
- Avoiding alcohol and limiting simple carbohydrates
- Achieving and maintaining a healthy weight through a combination of diet and exercise Medications play a critical role in managing severe hypertriglyceridemia, with fibrates (such as fenofibrate or gemfibrozil) being the first-line pharmacological treatment due to their efficacy in reducing triglyceride levels by 30-50% 1. Omega-3 fatty acids are also effective and can be used alone or in combination with fibrates 1. For patients with extremely high triglyceride levels (>1000 mg/dL), hospitalization may be necessary to implement complete fat restriction and intravenous insulin therapy to rapidly reduce triglyceride levels and prevent pancreatitis 1. Regular monitoring of lipid panels is essential to assess treatment efficacy and adjust the therapeutic plan as needed to achieve and maintain triglyceride levels below 500 mg/dL. Addressing underlying causes of hypertriglyceridemia, such as diabetes or hypothyroidism, and managing other cardiovascular risk factors are also critical components of comprehensive care 1.
From the FDA Drug Label
Fenofibrate tablets are also indicated as adjunctive therapy to diet for treatment of adult patients with severe hypertriglyceridemia. Niacin is also indicated as adjunctive therapy for treatment of adult patients with severe hypertriglyceridemia who present a risk of pancreatitis and who do not respond adequately to a determined dietary effort to control them
The treatment options for severe hypertriglyceridemia include:
- Fenofibrate as adjunctive therapy to diet 2
- Niacin as adjunctive therapy for patients who present a risk of pancreatitis and do not respond adequately to dietary efforts 3 Key considerations:
- Improving glycemic control in diabetic patients may obviate the need for pharmacologic intervention 2
- Markedly elevated triglyceride levels may increase the risk of developing pancreatitis 2
From the Research
Treatment Options for Severe Hypertriglyceridemia
The treatment of severe hypertriglyceridemia involves a combination of lifestyle changes and pharmacotherapy. The primary goal of treatment is to reduce the risk of pancreatitis and cardiovascular disease.
- Lifestyle Changes: Therapeutic lifestyle changes, such as a healthy diet and regular exercise, are essential for managing hypertriglyceridemia 4, 5, 6.
- Pharmacotherapy: Several classes of lipid-lowering agents are available for the treatment of hypertriglyceridemia, including:
- Fibrates: considered the first-line treatment for severe hypertriglyceridemia 7, 5.
- Omega-3 fatty acids: useful for reducing triglyceride levels 7, 5.
- Niacin: effective in combination with statins for reducing triglyceride levels 7, 5, 8.
- Statins: exhibit significant hypotriglyceridemic activity, especially in high doses 7, 4, 5.
- Orlistat: useful for reducing chylomicron production 7.
- Drug Combinations: In most patients with severe hypertriglyceridemia, drug combinations are needed to maintain an acceptable triglyceride concentration 7, 5.
- Hospitalization and Emergency Treatment: Patients with severe hypertriglyceridemia and abdominal pain or pancreatitis should be hospitalized and treated with hypolipidemic drugs, insulin/dextrose infusion, or therapeutic apheresis 7.
- Novel Therapies: Gene therapy is under development for patients with known genetic abnormalities of triglyceride metabolism 7, and anti-sense oligonucleotides and inhibitors of microsomal triglyceride transfer protein have shown significant TG lowering efficacy 5.
