Interferon in the Cerebrospinal Fluid of Children with Central Nervous System Disorders

摘要

Interferon was detected in the cerebrospinal fluid (CSF) of 26 of 51 children with aseptic meningitis, two of 44 with bacterial meningitis, and four of 118 with miscellaneous conditions including encephalitis, convulsive disorders and leukemia with neurological involvement. The geometric mean titre of interferon in mumps meningitis was seven to eight times higher than that in enteroviral meningitis; however, levels of interferon were not related to the concentration of leukocytes in CSF from these patients. Interferon titres were relatively greater at the height of the febrile response in children with mumps meningitis or enteroviral meningitis. There was no association between the presence of interferon in the CSF and the isolation of mumps virus or an enterovirus from the same specimen. Patients frequently developed homologous antibody one to three days after signs of aseptic meningitis, obscuring the relationship of interferon production to clinical improvement.
