Concentrations of interferon gamma (IFN-gamma) in the lumbar cerebrospinal fluid (CSF) of 30 children (mean age, 27 months) being treated for stage III (16 children) and stage II (14 children) tuberculosis meningitis (TBM) were determined by ELISA. Nine children with stage III TBM and six with stage II TBM received prednisone (4 mg/kg). Concentrations of IFN-gamma in 73 CSF specimens (18 from the first week of therapy, 20 from the second, 19 from the third, and 16 from the fourth) were determined. The mean concentrations were 780 pg/mL in the first week of therapy and 554 pg/mL, 529 pg/mL, and 269 pg/mL in the second, third, and fourth weeks, respectively. Tumor necrosis factor alpha (TNF-alpha) and interleukin-1beta (IL-1beta) concentrations in 56 specimens from 23 of these same children were determined by ELISA. The mean CSF TNF-alpha concentration in 12 specimens obtained during the first week of therapy was 17 pg/mL, and the mean was 11 pg/mL during each of the subsequent weeks (14 specimens were evaluated in the second week and 15 specimens in the third and fourth weeks of therapy). Mean IL-1beta concentrations in these same groups of specimens were 52 pg/mL, 43 pg/mL, 42 pg/mL, and 18 pg/mL. No correlation could be shown between cytokine concentration and stage of disease, and no differences existed between those who did and those who did not receive prednisone. A significant decline in IL-1beta concentrations was shown during the 4-week period, but none in TNF-alpha or IFN-gamma concentrations was noted. Persistently high CSF INF-gamma concentrations in cases of TBM (as in cases of aseptic meningitis but not bacterial meningitis) at the time of diagnosis suggest an immune response fundamentally different from that in bacterial meningitis.

A 37 year old male was admitted with the diagnosis of bacterial meningitis. Pneumococci were seen in the Gram stain of the cerebrospinal fluid. The clinical condition did not suggest severely raised intracranial pressure, there were no localizing signs and symptoms. CSF was turpid, with 20.100/3/mm(3) , mainly polymorphonuclear cells. Tumor necrosis factor alpha in CSp was greatly increased with 813 pg/ml. Parallel to the application of intravenous Penicillin G a CSF filtration was carried out. Within 214 h 225 ml CSF were filtrated through a Pall-filter, using a bidirectional pump. Cell count dropped to 720/3 cells/mm(3) , TNF-alpha to 39 pg/ml. The clinical course was uneventful, on day 12 the patient could be discharged without sequelae. CSF filtration may be a highly effective method to reduce from the CSF pathogenetically important cytokines, such as TNF-alpha, being responsible for intrathecal/meningeal inflammatory processes and triggered by cell-wall components of bacteria, e.g. pneumococci.
