[The role of mononuclear phagocytes in the immunopathogenesis of HIV infection]. / Rol' mononuklearnykh fagotsitov v immunopatogeneze VICh-infektsii.

The functional state of HIV-infected monocytes in 153 persons aged 20-59 years was studied. It was characterized by an increase in the production of monokines (TNF-alpha, IL1 beta) at stages IIB-IIIA, pronounced activation of the synthesis of DNA at stages IIB-IIC of the disease due to mass intracellular production of viral proteins. At the same stages an increase in the activity of lactate dehydrogenase and a decrease in the activity of succinate dehydrogenase were noted, which was indicative of an increase in the intensity of the process of anaerobic oxygenation at early of infection with the simultaneous decrease of the intensity of the tricarbon acid cycle and the subsequent suppression of the immunoregulating properties of monocytes.

In the course of 5 years 121 foreign and 13 Soviet military servicemen showed HIV infection; seven of them (officers and warrant officers) are still in service. As distinct from WHO requirements symptomless virus carriers are also registered. Infected servicemen constitute 1.5% from the total number of infected in the country.

PIP: During 1988-89 the medical department of the S. M. Kirov hospital diagnosed 50 HIV-infected military personnel who had contracted the disease in Africa. Among 270,000 prisoners from 17 countries the rate of HIV infection ranged from 11% to 26%. Among US Army recruits the rate of HIV seropositivity was found to be 1.5%. Among Navy soldiers the rate was 0.24%. During 1985-87, in the navies of different countries, 2051 men had contracted HIV infection, most of whom had no idea about transmission and prevention. At the Kirov military hospital during 1988-89 a comparison of HIV infection rate was made involving 545 people. Among foreigners the rate was 17.2 times higher than among citizens. In a massive screening experiment involving 47,447 people in Kalmykia a rate of 2.9% was found among local citizens compared to 1.9% among foreigners. Diagnosis relies on various antibody tests, of which the Welcozyme test system has yielded only a 2.3% rate of false positive results. In 1989 the immunological status of 73 false positive results from 20 HIV-infected people was examined. These investigations revealed that the absolute amount of T-4 cells, the index of differentiation of T-4/T-8, and the functional activity of lymphocytes diminished in the infected people, while a slight increase of T-8 count did occur. The study of the blood lymphocytes showed that in the infected people the activity of lactate dehydrogenase and mitochondrial isoforms of malate dehydrogenase decreased somewhat, while the activity of succinate dehydrogenase and especially of glucose-6-phosphate dehydrogenase increased. In persons infected with HIV, the T- suppressor cell count increased and T-helper cell count decreased, which leads to the decrease of the functional indices of the immune system. Military health services are obliged to inform the servicemen about AIDs for health protection and the spouses of those infected with HIV should also be notified.^ieng
