Abstract [en]

INTRODUCTION: Patients with schizophrenia have higher rates of mortality than the general population. Lower concentrations of the cerebrospinal fluid (CSF) monoamine metabolites homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) have been associated with suicidal, aggressive and impulsive behavior. Mortality has been suggested as a measure of impulsivity and a relationship between early death and lower concentrations of CSF monoamine metabolites has been reported but the studies are few with short periods of follow-up and small numbers.

AIM: The objective of this study was to investigate a relationship between early death and concentrations of CSF 5-HIAA and HVA.

METHODS: Three hundred and eighty-five inpatients with schizophrenia spectrum psychosis were lumbar punctured in a standardized manner and followed for a median of 26 years. Patients were searched to identify those who had died. Causes of death were obtained from the Causes of Death Register.

RESULTS: During the time of follow-up, 97 patients died. Schizophrenia spectrum psychosis patients died at an earlier age from both natural and unnatural causes of death. No significant associations were found between CSF 5-HIAA and HVA concentrations and non-suicidal death. Attempted suicide was not a risk factor for non-suicidal death at younger age.

CONCLUSION: Patients with schizophrenia spectrum psychosis die at an earlier age from both natural and unnatural causes of death. Attempted suicide is not a risk factor for non-suicidal death at younger age. Low concentrations of CSF HVA and 5-HIAA were not a risk factor for non-suicidal death at younger age in schizophrenia spectrum psychosis.
