From the Guidelines

The lipid panel should be repeated after a 12-hour fast to confirm the accuracy of the initial results and to establish a baseline for potential treatment. The patient's triglyceride level is markedly elevated at 14.03 mmol/L, which suggests severe hypertriglyceridemia, and this extreme elevation could be due to non-fasting status, medication effects, alcohol consumption, or underlying metabolic disorders 1. Before initiating treatment, confirmation with a fasting lipid panel is essential to establish accurate baseline values. The patient should be advised to avoid alcohol and high-fat meals for at least 24 hours before the repeat test. If the severe hypertriglyceridemia is confirmed, prompt treatment would be necessary to reduce the risk of acute pancreatitis, which becomes significant when triglycerides exceed 10 mmol/L. Initial management may include dietary modifications (low-fat diet), alcohol abstinence, and medications such as fibrates (e.g., fenofibrate 145 mg daily) or omega-3 fatty acids (2-4 g daily) 1. The elevated total cholesterol (6.62 mmol/L) and low HDL (0.71 mmol/L) also suggest dyslipidemia requiring comprehensive management once accurate values are established. According to the most recent guidelines, in adults with diabetes, it is reasonable to obtain a lipid profile at the time of diagnosis, at the initial medical evaluation, and at least every 5 years thereafter in patients under the age of 40 years 1. However, given the patient's age and lipid profile, more frequent monitoring may be necessary to assess the effectiveness of treatment and to adjust the management plan as needed. It is also important to note that lifestyle modification, including a Mediterranean-style diet, increased physical activity, and weight loss (if indicated), should be emphasized to improve the lipid profile and reduce the risk of developing atherosclerotic cardiovascular disease 1.

From the Research

Lipid Panel Results

The patient's lipid panel results are as follows:

  • Cholesterol: 6.62 mmol/L
  • HDL: 0.71 mmol/L
  • Triglycerides: 14.03 mmol/L

Should the Lipid Panel be Repeated?

According to the study 2, it is acceptable to screen with nonfasting lipids. However, when LDL-C or TG screening results are abnormal, the clinician should consider obtaining fasting lipids. In this case, the patient's triglyceride level is significantly elevated (14.03 mmol/L), which may indicate hypertriglyceridemia.

Hypertriglyceridemia

The study 2 recommends reporting potentially actionable abnormal lipid test results, including fasting triglycerides (TG) ≥500 mg/dL, as hypertriglyceridemia. Although the patient's triglyceride level is not in mg/dL, converting it to mg/dL (1 mmol/L = 88.57 mg/dL) yields a value of approximately 1245.41 mg/dL, which is above the threshold for hypertriglyceridemia.

Repeat Testing

Given the significantly elevated triglyceride level, it may be necessary to repeat the lipid panel to confirm the results and rule out any potential errors or laboratory variations. Additionally, the study 2 recommends lipid measurements 4-12 weeks after a change in lipid treatment, which may not be applicable in this case since there is no mention of the patient undergoing lipid treatment.

Advanced Lipid Testing

The study 3 suggests that advanced lipid tests, such as measurement of low-density lipoprotein particle number, can assist the clinician when assessing a patient's cardiovascular disease risk. However, this may not be necessary in this case, as the patient's significantly elevated triglyceride level is already a clear indicator of potential cardiovascular risk.

Management of Hypertriglyceridemia

The studies 4, 5, and 6 discuss the management of hypertriglyceridemia using various treatments, including omega-3 fatty acids, fibrates, and niacin. However, these studies do not provide direct guidance on whether to repeat the lipid panel in this specific case.

Decision to Repeat Lipid Panel

Based on the significantly elevated triglyceride level and the potential for hypertriglyceridemia, it may be reasonable to repeat the lipid panel to confirm the results and guide further management. However, this decision should be made in consultation with a healthcare professional, taking into account the patient's overall clinical profile and medical history.
