Recent-onset medication-free bipolar disorder is associated with higher triglyceride levels, according to a recent study. These findings are suggestive of early metabolic dysregulation prior to long-term psychotropic medication exposure. Therefore, lower omega-3 polyunsaturated fatty acid (PUFA) levels in individuals with bipolar I disorder represent a potential therapeutic target for additional investigation. Cardiometabolic risk assessments were compared in individuals with bipolar I disorder experiencing a first manic or mixed episode or an early depressive episode (n=117) and healthy subjects (n=56). Patients were medication-free at assessment and had no or limited exposure to mood-stabilizer or antipsychotic medications prior to the current admission. Researchers found:
- Following adjustment for demographic variables (ie, age, gender, and parental education), significantly higher fasting triglyceride levels were observed in the bipolar group compared to the healthy group (121.7 mg/dL vs 87.0 mg/dL).
- There were no clear trends for other metabolic indicators, including blood pressure, body mass index, and fasting glucose.
- 19% of the bipolar group and 6% of the healthy group met the criteria for metabolic syndrome.
- The omega-3 index was lower in the bipolar group (3.4% vs 3.9%).
