Effects of PM2.5 pollution and single nucleotide polymorphisms of neurotrophin signaling pathway genes acting together on schizophrenia relapse

Purpose The objective of this study was to investigate the co-effect of long-term exposure to atmospheric particulate matter PM 2.5 and single nucleotide polymorphisms on schizophrenia relapse. Methods A total of 332 patients with schizophrenia were recruited. Genotyping of eight SNPs for five genes...

Description
Summary:Purpose The objective of this study was to investigate the co-effect of long-term exposure to atmospheric particulate matter PM 2.5 and single nucleotide polymorphisms on schizophrenia relapse. Methods A total of 332 patients with schizophrenia were recruited. Genotyping of eight SNPs for five genes along the neurotrophin signaling pathway was performed by the Sequenom Massarray technology platform. Based on the data from the monitoring stations, the PM 2.5  level of each patient's residence was assessed by the inverse distance weighting method using Arc GIS software. Cox regression analysis was used to determine independent risk factors. The relationship between PM 2.5  levels and the risk of schizophrenia relapse was evaluated using the restricted cubic spline (RCS) method. Results In this study, a total of 191 of 332 patients with schizophrenia relapsed with hospitalization. The risk of schizophrenia relapse was 13.62 (95% CI 8.29 to 22.37) in areas with PM 2.5 concentrations of 48.43 to 75.35 µg/m 3 . The risk of schizophrenia relapse was 5.81 (95% CI 3.58–9.42, p
