Due to the steady increase in the number of children with autism and the high heterogeneity of clinical groups, the diagnosis of these disorders and their severity is an urgent problem in modern medicine. In the course of the work, 126 children from 3 to 13 years old with typical neurodevelopment and with severe and mild autism spectrum disorders (ASD) were examined. Disease severity was determined according to the Childhood Autism Rating Scale (CARS). The levels of pro-/anti-inflammatory cytokines and neurotrophic factors (nerve growth factor beta and brain-derived neurotrophic factor) in blood plasma were assessed by enzyme immunoassay. Associations between indicators in each group of patients were assessed using the Spearman test and visualized as a heatmap of correlations. Statistical data processing was carried out in the R software. Significantly high levels of IL-4 in blood plasma and a decrease in the number of significant correlations within/between systems were revealed in children with mild autism compared with children with typical neurodevelopment. Such data can probably reflect the theory that some children with ASD are characterized by slow brain development, as a variant of the evolutionary norm. On the contrary, in children with severe ASD, high systemic levels of IL-6 and IFNg are shown against the background of low values of IL-10, IL-1β, TNFα and NGFβ, supported by the almost complete absence of intra/ and intersystem interactions. This may act as an indicator of maladaptation of the immune and nervous systems in severe autism, which contributes to the pathogenesis of the disease. Thus, a set of indicators: high levels of key pro-inflammatory cytokines - IL-6 and IFNg, low levels of IL-10, NGFβ and disintegration of the cytokine and nervous systems in the periphery can be proposed as an approach to indicate the severity of the condition in children with ASD.
