Research Abstract

The aim of the study was to explore biological markers in peripheral plasmasamples from non-medicated subjects with high-functioning ASD.(Experiment 1) A multiplex assay for cytokines and chemokines was applied to plasma samples frommale subjects with high-functioning ASD (n = 28) and matched controls (n = 28). Among a total of 48 analytes examined, theplasma concentrations of IL-1β, IL-1RA, IL-5, IL-8, IL-12(p70), IL-13, IL-17 and GRO-αwere significantly higher in subjects withASD compared with the corresponding values of matched controls after correction for multiple comparisons.(Experiment 2) Plasma levels of 25 amino acids in male children (n= 23) with ASDand matchedcontrols (n= 22) were determined using high-performance liquid chromatography. Compared with controls, subjects with ASD showed higher levels of plasmaglutamate and lower levels of plasma glutamine. Using discriminantanalysis with logistic regression, the two values of plasma glutamate and glutamine were shown to differentiate theASDgroup from the control group; the rate of correct classification was 91%.Theseresults suggest that abnormal immune responses as assessed by multiplex analysis and plasma glutamate and glutamine levelsmay serve as the biological markers for ASD.
