[Amplification of the activity of HIV-1 isolates purified from seropositive children after cryopreservation of persistently-infected cells]. / Usilenie aktivnosti izoliatov VICh-1, vydelennykh ot seropozitivnykh detei, posle kriokonservatsii persistentno infitsirovannykh kletok.

HIV-1 strains MC-1974 and MC-1978 were isolated from children infected in hospital. Both children presented with symptoms of HIV infection by the moment the blood samples for virus isolation were collected. In vitro the isolated strains showed weak infective activity and caused no cytopathic effect in sensitive cells. It may be explained by azidothymidine antiviral therapy or by initial immunodeficient status of both children not caused by HIV infection. Virus activity was enhanced in both cultures after reactivation of Jurkat-tat cells persistently infected with MC-1974 and MC-1978 strains after cryopreservation. Viruses isolated from culture fluid effectively infected Jurkat-tat cells. The infection was associated with formation of syncytia, accumulation of viral particles detected by electron microscopy and of intracellular antigens detected by fluorescent antibody technique and by immunoblotting. The results suggest the presence in the body of infected children and in Jurkat-tat-1974 and Jurkat-tat-1978 persistent lines of a viral genome containing all virusspecific genes necessary for productive expression of HIV-1.

[Clinical manifestations and the problems of classification of HIV infection]. / KLinicheskie proiavleniia i voprosy klassifikatsii VICh-infektsii.

The clinical manifestations and some immunological parameters (CD4 lymphocytes, CD4/CD8 ratio, IgM, IgA, IgG levels, skin test) were examined in 226 adult patients (148 males and 78 females) infected with HIV. These included 58 (26%) asymptomatic patients with seropositive test, 109 (48%) with the only clinical manifestation generalized lymphadenopathy; 54 (24%) with AIDS-related infections, 5 (2%) with AIDS. A subsequent follow-up of 3 months to 3 years demonstrated that AIDS developed in 7 patients, 9 died. The period of infection with HIV and death ranged from 1.5 to 9 years. The signs of cell immunodeficiency were found in 70% of the examinees. Recommendations are given on the classification of HIV infection.

[HIV infection: the venereological aspects of the problem]. / VICh-infektsiia: venerologicheskie aspekty problemy.

The paper is concerned with the diagnosis, clinical picture and the treatment policy of 7 patients suffering from associated syphilis and HIV infection. Some peculiarities were marked in the course and clinical picture of the syphilitic infection: the reduction of the time of the development of secondary syphilis, odd clinical manifestations, and early damage to the nervous system. Recommendations are given for CSF examination and treatment of all the patients with associated syphilis and HIV infection. Attention is paid to the necessity of examining all the patients with HIV infection for diseases transmitted sexually and vice versa.
