[Tetanus antitoxin in serum and cerebral spinal fluid in viral meningitis in children (author's transl)].

Tetanus antitoxins were measured in serum and cerebro spinal fluid from 58 children--35 boys and 23 girls--with viral meningitis. The concentrations of IgG, IgA and IgM were also determined. The appearance of tetanus antitoxins in cerebral spinal fluid depends on absolute antitoxin levels in serum as well as on the antitoxin/IgG ratio. Antitoxin/IgG ratios in serum and cerebro spinal fluid were in the same order of magnitude. Detection of tetanus antitoxins in the cerebral spinal fluid of children with viral meningitis shows clearly that antibody found in cerebral spinal fluid is not an absolute proof of a certain disease. The results further indicate that local production of IgG antibody cannot be postulated by detecting certain antibodies in the CSF. It is also necessary to prove that antibody/globulin ratios are of significantly different magnitude in serum and CFS.
