Improvements in metabolic abnormalities among overweight schizophrenia and bipolar disorder patients

Purpose: As weight-gain and metabolic abnormalities during treatment with psychotropic drugs are of great concern, we evaluated effects of psycho-education and medical monitoring on metabolic changes among severely mentally ill patients. Materials and methods: During repeated, systematic psycho-education about general health among 66 consecutive patients diagnosed with DSM-IV-TR schizophrenia (n = 33) or type-I bipolar disorder (n = 33), we evaluated (at intake 1, 2, 3, and 6 months) clinical psychiatric status, treatments and doses, recorded physiological parameters, and assessed attitudes about medication. Results: At intake, patients with schizophrenia vs bipolar disorder were receiving 3-7 times more psychotropic medication, with 14% higher initial body-mass index (BMI: 29.1 vs 25.6 kg/m(2)), 12 times more obesity, and significantly higher serum lipid concentrations. During 6-months follow-up, among bipolar disorder patients, polytherapy and serum lipid concentrations declined more than among schizophrenia patients (e. g., total cholesterol + triglycerides, by 3.21 vs 1.75%/month). BMI remained stable. Declining lipid levels were associated with older age, bipolar disorder, being unemployed, higher antipsychotic doses, and lower initial BPRS scores (all P <= 0.001). Conclusions: Psychotropic treatments were more complex, and metabolic measures more abnormal among bipolar disorder than schizophrenia patients. Intensive psycho-education, clinical monitoring, and encouragement of weight-control for six months were associated with improvements in metabolic measures (but not to BMI), and more realistic attitudes about medication.
