The existing evidences show that serum PRL is elevated in schizophrenic patients treated with olanzapine. However, little is known about the long-term effects of olanzapine on PRL levels and weight gain in female patients with schizophrenia. Materials and methods: This study addressed this issue by investigating the relationship between serum PRL level and body mass index (BMI). Seventy-nine female patients with first-episode schizophrenia were recruited and received olanzapine monotherapy for 12 weeks. Serum PRL level and BMI were measured at baseline and at 4, 8, 12 weeks. Thirty-five age-matched healthy female individuals were recruited as controls. The severity of psychiatric symptoms was evaluated using the Positive and Negative Syndrome Scale. Results: The olanzapine treatment for 12 weeks significantly increased serum PRL (P<0.01) level and BMI (P<0.01). A positive correlation between the pre- and posttreatment changes in serum PRL level and BMI was observed (r=0.247, P=0.028). Conclusion: Our findings suggest that PRL might conceivably modulate weight gain in female patients with schizophrenia receiving olanzapine treatment; however, the exact mechanism remains unclear.Keywords: schizophrenia, prolactin, BMI, olanzapineYang FChen LFang XZheng KZhu CXu CZhang CTang WDove Medical PressarticleSchizophreniaProlactinBMIOlanzapineNeurosciences.
