| Sumario: | Daniel Neider, Leif H Lindström, Robert Bodén Department of Neuroscience, Psychiatry, Uppsala University, Uppsala University Hospital, Uppsala, Sweden Background: The objective of this study was to investigate the association between 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) in cerebrospinal fluid (CSF), bullying, and later suicide among patients with schizophrenia. Methods: Ninety-nine patients with schizophrenia were included. Correlations of clinical factors, 5-HIAA and HVA, and later suicide were investigated. Results: Twelve patients committed suicide (12%) during a 28-year follow-up period. Later suicide was correlated to bullying in childhood (P=0.02) and a lower quotient of HVA/5-HIAA in CSF (P<0.05). Conclusion: Suicide in schizophrenia is related to childhood exposedness and CSF neurotransmitter levels. Keywords: psychosis, risk factors, bullying, HVA, 5-HIAA, CSF |
