Changes of Serum Insulin-like Growth Factor-2 Response to Negative Symptom Improvements in Schizophrenia Patients Treated with Atypical Antipsychotics. Curr Med Sci 2020; 40:563-569.

Abstract
Accumulating evidence suggests that a disruption of early brain development, in which insulin-like growth factor-2 (IGF-2) has a crucial role, may underlie the pathophysiology of schizophrenia. Our previous study has shown that decreased serum IGF-2 was correlated with the severity of psychopathology in patients with schizophrenia. Here we conducted a prospective observation trial to investigate the effects of atypical antipsychotics on serum IGF-2 level and its relationship with clinical improvements in schizophrenia patients. Thirty-one schizophrenia patients with acute exacerbation and 30 healthy individuals were recruited in this study. Psychiatric symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS) and serum IGF-2 levels were determined using ELISA. We found that schizophrenia patients with acute exacerbation had lower serum IGF-2 levels than control individuals at baseline (P<0.05). After 2 months of atypical antipsychotic treatment, a significant improvement in each PANSS subscore and total score was observed in patients (all P<0.01), and the serum IGF-2 levels of patients were significantly increased compared with those at baseline (203.13±64.62 vs. 426.99±124.26 ng/mL; t =-5.044, P<0.001). Correlation analysis revealed that the changes of serum IGF-2 levels in patients were significantly correlated with the improvements of negative symptoms (r=-0.522, P=0.006). Collectively, our findings demonstrated changes of serum IGF-2 response to improvements of negative symptoms in schizophrenia patients treated with atypical antipsychotics, suggesting that serum IGF-2 might be a treatment biomarker for schizophrenia.

Abstract
Adjuvant therapy is a common therapeutic strategy used for schizophrenia management. Oxytocin has shown promising results as antipsychotic adjuvant in patients with schizophrenia. Although short-term clinical studies have indicated tolerability and no major side-effect manifestation, long-term studies remain needed. In this study, we investigated whether oxytocin chronic administration in rats may lead to brain DNA damage by comet assay. Our results suggest that 21 and 56-day treatment with once daily intraperitoneal oxytocin (0.1, 1.0 and 10.0 mg/kg) may cause substantial DNA damage in hippocampus. We have not found differences on body weight gain. Our findings also point that further clinical and preclinical studies evaluating oxytocin safety after chronic exposure are necessary.
