Plasma lipids, lipoproteins and hormones levels during olanzapine treatment in psychosis and depression.
Weight gain is common adverse effect associated with the use of most typical and atypical antipsychotic. Aim of this study was to investigate plasma lipids, lipoproteins and some hormones levels during olanzapine treatment in patients with psychosis. The study population comprised twenty nine patients (29) diagnosed with psychosis and eleven patients (11) with endogenous depression. Plasma cholesterol, triglicerides, phospholipids, high-density lipoprotein cholesterol (HDL-C), very-low-density lipoprotein cholesterol (VLDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A-I (ApoA-I) and apolipoprotein B (Apo B), and hormones - prolactin, cortisol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estradiol were measured by auto-analyzer and by classic photometric methods. All measurements were performed before and during one-year treatment with olanzapine and antidepressant. Treatment of the schizophrenic patients with olanzapine caused a great metabolic impact that is primarily expressed in body mass, cholesterol increase and statistically significant rise of BMI, respectively. Body mass increase could be explained by the fact that olanzapine blocked not only dopaminergic, serotonergic, cholinergic, alpha-adrenergic but histaminergic receptors as well.
