Host immune profiles and genotyping analysis of HIV-1 among Japanese hemophiliac patients

Host immune profiles and genotyping analysis of HIV-1 among Japanese hemophiliac patients

Fukushima Journal of Medical Science 45(1): 53-62

We studied the immune profiles of 21 Japanese hemophiliac patients who had been infected with human immunodeficiency virus type 1 (HIV-1) by the blood preparations during the 1982-84 period, and carried out the genotyping of HIV-1 V3 region for uncultivated peripheral blood mononuclear cells (PBMC) from 8 patients. Ten years after infection, asymptomatic carrier (AC, 14 cases) yet outnumbered those in AIDS related complex (ARC, 4 cases) and AIDS (3 cases), and the CD4+ and CD8+ T-cell numbers were not correlated with clinical stages. Macrophage tropic sequences, as identified according to the known tropism determinants, appeared to be more frequent as the CD4+ T-cell numbers were higher. There was no correlation of the cell tropism with the disease stages, however. It might be due to HIV-1 of CD4+ T-cells being more productive. The mutation in the V3 region appears to differentially influence the escape from antibody attack and clinical stages, and the cell tropism may not be related to the cell immunity of the host.
