[The phenomenon of HLA antigen modification in meningococcal infection].

212 patients with the generalized forms of meningococcal infection have been examined. The intensity and quality of lymphocytotoxic reaction in the acute phase and the convalescence period of the disease have been analyzed and the blank calculation has been made at different clinical forms of meningococcal infection. The formation of modified tissue antigens at the acute stage of the disease in the presence of intoxication is shown and the probable role of the intensity of bacteremia in this formation is discussed.

[Distribution of HLA antigens in patients with meningococcal infection at different times of year].

The character of the distribution of the antigens of the HLA system at different seasons has been studied in 160 patients with generalized forms of meningococcal infection. The occurrence of HLA-Bw16 (the marker of the population gene of susceptibility to meningococcal infection) has proved to be inversely correlated with the seasonal morbidity level.
