Abstract:
Bacterial meningitis has a poor prognosis and neurologic complications. The present study aimed to investigate the cytokine/chemokine network in cerebrospinal fluid (CSF) from children with bacterial meningitis and aseptic meningitis. Interleukin (IL)-1beta, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, interferon-gamma, tumor necrosis factor-alpha, granulocyte colony-stimulating factor, granulocyte monocyte colony-stimulating factor, monocyte chemoattractant protein-1 and macrophage inflammatory protein-1beta, were measured simultaneously in CSF supernatants. We found that, IL-17 was significantly elevated in CSF with bacterial meningitis. We believe that IL-17 plays a key role in neutrophil infiltration into CSF and neuronal protection in bacterial meningitis.
