Enteroviral meningitis reduces CSF concentration of A β42, but does not affect markers of parenchymal damage

AbstractBiomarkers classically studied in Alzheimer ’s disease have been analyzed in numerous central nervous system infections in adults, but there are scarce data on these biomarkers in children. Enteroviruses appear to be the most common cause of aseptic meningitis throughout the world. The aim of the study was to investigate neuroinflammatory p roperties of non-polio enteroviruses by measuring CSF concentrations of biomarkers that are involved in neuropathological pathways of neurodegenerative disorders. We measured Aβ42, t-tau, and S100B concentrations in 42 children with enteroviral meningitis (EM) compared to control group without cent ral nervous system infection. We found enteroviral meningitis (EM) to reduce CSF concentration of Aβ42 (median, 1051.1 pg/mL; interquartile range (IQR), 737.6–1559.5 vs. median, 459.4 pg/mL; IQR, 312.0–662.0,p <  0.001). In contrast, CSF concentrations of t-tau and S100B were not affected by EM. There was a correlation between total neutrophil count in CSF and Aβ42 (R = − 0.59,p <  0.001). Absolute number of mononuclear cells in the CSF correlated with CSF t-tau (R = 0.41,p <  0.05). Both correlations remained significant after adjustment for age, blood leukocytes, serum CRP, CSF leukocytes, and CSF protein concentration.
