[Immunologic methods in the diagnostics and treatment of nosocomial cases of pneumonia].

The publications on the etiology, bacteriological and immunochemical diagnostics of pneumonia, as well as on the role of immunotherapy and prophylaxis in the treatment of this disease, are analyzed. The importance of immunological methods in the diagnostics of pneumonia is pointed out. Approaches to the immunotherapy and immunoprophylaxis of pneumonia are updated.

[Detection rate and distribution pattern of HIV infected patients in the emergency room of a hospital].

HIV positive patients needing urgent treatment have become reality in the clinical practice of the multiprofile hospital of the Sklifosovsky Research Institute of Emergency Aid. 243,030 patients and 55,163 donors were examined at the Laboratory of Clinical Immunology and AIDS Diagnostics during the period of 1989-2001, and among the examinees 814 patients and 13 donors were found to be HIV-infected. The highest detection rate of HIV-infected patients was registered in the poisoning center, the somatic-psychiatric and endotoxicosis departments.

[Inhibition effect of merthiolate used as vaccines preservative on the oxygen-dependent metabolism of neutrophil granulocytes].

The influence of the newly developed complex vaccine Pyopol, containing the antigens of opportunistic microorganisms and polyoxydonium used as immunomodulator, on the oxygen-dependent metabolism of neutrophils was studied. The study revealed that the main components of the vaccine, both individually and in association, did not change cellular activity in the range of concentrations used in this study. The inhibition of the oxygen-dependent metabolism of neutrophil granulocytes in the presence of native or weakly diluted vaccine occurred due to the cytotoxic effect of thimerosal used as preservative.

[Bacteriological monitoring of infective agents of purulent septic diseases in an emergency hospital].

During the period of 1995-2001 bacteriological examination of 13,842 patients with purulent septic diseases (PSD) was carried out. The statistical processing of data revealed that equalization of the dynamic rows of intensive and extensive values characterizing the number of patients with PSD caused by etiologically important infective agents made it possible to evaluate the reliability of information. A trend to increased etiological importance of the genera Pseudomonas, Escherichia and Klebsiella was established.

[Comparative population study of the etiological role of causative agents of purulent inflammatory diseases and serum antibodies to antigens of opportunistic microorganisms].

The comparative study of the relationship between the levels of serum antibodies to the antigens of opportunistic microorganisms of 5 genera (Pseudomonas, Proteus, Staphylococcus, Klebsiella, Escherichia) and the microbial status was carried out. A total of 854 patients from 10 profile departments of a surgical hospital were examined. Population analysis and statistical methods of processing the results of the examination of 353 practically healthy subjects and 268 blood and plasma donors permitted the norms for the levels of specific antimicrobial antibodies (decreased, normal, elevated levels) were established.
