Levels of triglycerides, cholesterol, LDL, HDL and glucose in patients with schizophrenia, unipolar depression and bipolar disorder

AimsThe aim of this study is to investigate differences in triglycerides (TGA), cholesterol (TC), HDL, LDL and glucose (FPG) levels in patients with acute schizophrenia, unipolar depression, bipolar depression and bipolar mania.ResultsResults for 2305 Caucasian patients were included in the study (1377 women, 59.7%; mean age 45.6). Mean TGA level was: schizophrenia: 139.9 ± 90.6 mg/dL, unipolar depression: 125.4 ± 70.8 mg/dL, bipolar disorder: 141.1 ± 81.9 mg/dL, bipolar depression: 147.7 ± 82.8 mg/dL mg/dL, bipolar mania: 120.2 ± 76.1 mg/dL, inter-group differences were significant (p < 0.001). Mean TC level was: schizophrenia: 188.5 ± 40.4 mg/dL, unipolar depression: 198.8 ± 50.7 mg/dL, bipolar disorder: 194.4 ± 48.3 mg/dL, bipolar depression: 198.9 ± 48.8 mg/dL, bipolar mania: 180.1 ± 43.8 mg/dL, inter-group differences were significant (p < 0.001). Mean HDL level was: schizophrenia: 45.3 ± 13.9 mg/dL, unipolar depression: 48.1 ± 14.8 mg/dL, bipolar disorder: 45.4 ± 15.3 mg/dL, bipolar depression: 45.1 ± 15.4 mg/dL, bipolar mania: 46.4 ± 15.1 mg/dL, inter-group differences were significant (p < 0.001). Mean LDL level was: schizophrenia: 115.4 ± 34.7 mg/dL, unipolar depression: 125.7 ± 44.1 mg/dL, bipolar disorder: 120.9 ± 42.1 mg/dL, bipolar depression: 124.5 ± 43.1 mg/dL, bipolar mania: 109.3 ± 36.9 mg/dL, inter-group differences were significant (p < 0.001). Mean FPG level was: schizophrenia: 95.9 ± 24.9 mg/dL, unipolar depression: 94.8 ± 22.9 mg/dL, bipolar disorder: 97.2 ± 24.4 mg/dL, bipolar depression: 98.3 ± 25.3 mg/dL, bipolar mania: 93.9 ± 21.1 mg/dL, inter-group differences were not significant (p = 0.08). Odds ratios for glucose and lipids abnormalities, correlations with age, sex distribution in diagnostic groups for normal ranges of glucose and lipids, differences in glucose and lipids levels between the age groups were also calculated.ConclusionsOur results confirm that there is a high prevalence of lipid and glucose abnormalities in patients with schizophrenia and mood disorders (both unipolar and bipolar). However, we have demonstrated that these diagnostic groups differ in terms of types and frequency of these metabolic dysfunctions. Women and patients aged 40+ are at particularly high risk.
