- There is a lack of biomarkers in schizophrenia and the mechanisms underlying the observed deficits in social functioning are poorly understood. This cohort study aimed to explore whether neurotransmitter neuropeptide Y (NPY) in cerebrospinal fluid (CSF) from patients with schizophrenia is correlated to social function and clinical variables. A further aim was to determine whether baseline levels of NPY were associated with subsequent 3-year outcome. Fifty-six consecutively admitted patients with schizophrenia were included and underwent lumbar puncture and symptom ratings before antipsychotic treatment. NPY levels in CSF were determined by radioimmunoassay. Social function (Social Competence and Social Interest) was assessed by Nurses' Observation Scale for Inpatient Evaluation while psychiatric symptoms were rated using the Comprehensive Psychopathological Rating Scale. Three-year outcome was assessed with the Strauss–Carpenter Outcome Scale. Cross-sectional analysis showed a correlation between level of NPY and Social Competence at index admission (rs = 0.37, p < 0.05). The longitudinal analysis (i.e. at the 3-year follow-up) indicated that, for each standard deviation increase in baseline NPY, there was an increased risk of being unemployed (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.07–3.82), having moderate or severe symptoms (OR 3.09, CI 1.30–7.32) or being hospitalized at least 6 months the previous year (OR 3.24, CI 1.09–9.64). However, NPY was not correlated to Social Interest or clinical variables at index admission. In conclusion, NPY levels in CSF are correlated to Social Competence and seem to predict some aspects of longitudinal outcome in schizophrenia.
