[The characteristics of the present-day clinical course of tuberculous meningitis].

Clinical patterns of tuberculous meningitis have been analyzed for 32 admissions to the bacterial meningitis department of the 2nd Moscow Infection Hospital in 1983-1991. Early diagnosis of tuberculous meningitis caused great difficulties because of rare cases of tuberculous history, atypical symptoms (an acute onset, in particular), an obscure meningeal syndrome, rare neurological symptoms, atypical liquor characteristics (frequent neutrophil pleocytosis, a small protein rise, normal glucose). Secondary bacterial meningitides presented most serious difficulties for differential diagnosis. So did cerebral abscesses and viral meningitis. Antituberculous therapy should be started at first sings of tuberculous nature of meningitis as the disease outcomes are determined to a large extent by early administration of proper treatment.

[The Fc-dependent binding of gram-negative bacterial endotoxins by human blood polymorphonuclear leukocytes].

The treatment of thin blood smears with antibodies to glycolipid of chemotype Re, conjugated with horseradish peroxidase, revealed that under physiological conditions about 3.5% of leukocytes bound endotoxin of gram-negative bacteria by means of the Fc-dependent mechanism. In addition, about 4.9% of leukocytes may bind endotoxin as the result of the treatment of blood smears with the preparation of glycolipid of chemotype Re. At the acute period of bacterial cerebrospinal meningitis leukocytes capable of binding endotoxin in the body or during the treatment of blood smears are practically absent. The conclusion was made that the binding of endotoxins by leukocytes had a protective character.

[Antibody titers to glycolipid chemotype Re and endotoxin binding by leukocytes in suppurative meningitis].

The state of immunity to endotoxin of gram-negative bacteria in 45 patients with purulent meningitis caused by meningococci and Escherichia was studied. For comparison, similar characteristics in 35 practically healthy persons were studied. The state of immunity was evaluated by antibody titers in the passive hemagglutination inhibition test with chemotype Re glycolipid and by the content of polymorphonuclear leukocytes, capable of binding endotoxin in the blood of the examinee (in vivo determination), and leukocytes, capable of binding endotoxin during the treatment of thin blood smears (in vitro determination). Leukocytes bound with endotoxin were detected in blood smears in the enzyme immunoassay with the use of the conjugate of horse-radish peroxidase with antibodies to chemotype Re glycolipid. The study revealed that the acute period of bacterial meningitis was characterized by considerable suppression of antiendotoxin immunity. Leukocytes, binding endotoxin in vivo, as well as leukocytes, capable of binding endotoxin in vitro, were practically absent in the patients at the time of their admittance to the hospital. After treatment the characteristics of antiendotoxin immunity restored practically to normal values.
