[Serological analysis of blood and cerebrospinal fluid in patients with meningeal tuberculosis]. / Serologicheskie issledovaniia krovi i spinnomozgovoi zhidkosti u bol'nykh tuberkulezom mozgovykh obolochek.

The results of ++clinico-serological examination of 81 subjects with meningeal diseases are given; among them 53 had tuberculous meningitis. The authors applied complement fixation (CFT) and indirect hemagglutination tests (IHT) with tuberculin. The high diagnostic significance of CFT and low efficiency of IHT were established in tuberculous meningitis detection. It is expedient to determine simultaneously the antituberculous antibodies in the blood serum and cerebrospinal fluid of the examined patients. Simultaneous performance of CFT during the follow-up increases its diagnostic potentialities to 88.6%. Detection of complement-binding antibodies only in CFT is, in most cases, a sign of isolated tuberculous meningitis. Detection of specific antibodies only in the blood serum of tuberculous meningitis patients is an indirect evidence of generalized process.
