摘要: Lindqvist D, Janelidze S, Erhardt Traskman-Bendz L, Engstrom G, Brundin L. CSF biomarkers in suicide attempters - a principal component analysis. Objective: The objective of the present study was to identify biological patterns (factors) among 20 cerebrospinal fluid (CSF) and subsequently analyse their association with suicidal behaviour. Method: We measured kynurenic acid, orexin, homovanillic acid (HVA), 5-hydroxyindoleacetic (5-HIAA), 3-methoxy-4-hydroxyphenylglycol, chemokines, matrix metalloproteases cytokines 124 drug-free attempters. Patients were evaluated for suicidality psychiatric symptoms using well-defined rating scales followed-up regarding future suicide. used analysis factors substances. Results: Four extracted from biomarkers, explaining 52.4% total variance. Factors 1 2 characterized by high loadings chemokines respectively. They both associated severe depressive symptoms. Factor also intent. 4 strong monoamine metabolites 5-HIAA HVA, as well orexin interleukin-6. High scores on this factor found patients who performed violent attempt completed Conclusion: Our results suggest that specific combinations may discriminate between types behaviour indicate increased risk (Less)
