Summary

Newer antipsychotics like olanzapine and quetiapine can cause severe hypertriglyceridemia, a serious lipid disorder. Monitoring serum lipids is crucial for patients on these medications.

Area of Science:

  • Pharmacology
  • Metabolic Disorders
  • Psychiatry

Background:

  • Atypical antipsychotics offer improved efficacy and reduced extrapyramidal side effects compared to older typical antipsychotics.
  • However, newer agents are linked to metabolic issues including obesity and new-onset diabetes.
  • Previous reports noted modest hypertriglyceridemia with certain antipsychotics, including olanzapine.

Purpose of the Study:

  • To summarize cases of severe hypertriglyceridemia associated with olanzapine and quetiapine.
  • To highlight the incidence and severity of these lipid abnormalities in an inpatient psychiatric setting.

Main Methods:

  • Retrospective summary of 14 inpatient cases with severe hypertriglyceridemia (>600 mg/dL).
  • Analysis of patients treated with olanzapine or quetiapine at Oregon State Hospital.

  • Review of serum triglyceride levels, onset of symptoms, and development of diabetes.

    • Main Results:

    • 14 cases of severe hypertriglyceridemia (>600 mg/dL) were identified, with 7 exceeding 1,000 mg/dL.
    • Four patients developed new-onset diabetes concurrently.
    • Most cases (9/14) occurred within the first 8 months of treatment, with 3 within 3 months.

    Conclusions:

    • Olanzapine and quetiapine are associated with severe hypertriglyceridemia, even with modest weight gain.
    • The biochemical mechanisms remain unclear.
    • Clinical monitoring of serum lipids is essential for patients receiving these novel antipsychotics.
